[0033] Figure 4 is the front view of the concrete slab 18 of the flywheel electricity generation device along with the side view of the basement. With reference to Figure 4, the front view of the concrete slab 18 is disclosed along with the basement 29 of the flywheel power generation system. The said side view of the flywheel system is installed on the top surface of the concrete slab 18 and side view of the generator system is installed in the basement 29.

[0034] Figure 5 is the perspective view of the busbar and friction connector of the flywheel electricity generation device. With reference to Figure 5, the perspective view discloses the cables 19 that supply electricity to the motor, electric busbar 20, busbar insulator 21, friction connector insulator 22, spring 23, friction connector 24. The AC or DC drive supplies electricity to the motor 7 via cable 26, bus bar 20, friction connector 24 and cable 19. The electric busbar 20 is installed on the foundation plate or on the surface of concrete slab 18 under the flywheel 1. And the friction connector 24 attached to the said flywheel 1, the said friction connector 24 continue rotate with the flywheel 1 by touching to busbar 20, thereby supplying power to the motor. More than one additional busbar system will be used for power and control wiring.

[0035] Figure 6 is the perspective view of the tire wheel path 8, standby wheel path 27, concrete slab 18 and basement 29 of the flywheel electricity generation device. With reference to Figure 6, the perspective view discloses the assembly in which the concrete slab 18 of sufficient size and capacity is installed on the basement 29 wherein the slab hole 28 and foundation bolts are located at the center of the concrete slab 18 and the tire wheel 8 and standby wheel path 27.

And the tire wheel 2, taking complete load of the said flywheel 1, will be rotated circularly from the drive assembly on tire wheel path 8. The standby wheel 9 is installed parallel to the tire wheel 2, with the flywheel 1 in the direction below, the keeping a sufficient distance from the standby wheel path 27. The said standby wheel 9 contains more than one limit switches fixed on the standby wheel path 27. If the air in the all tire wheel 2 is reduced, the standby wheel 9 will touch the standby wheel path 27 and take the load of flywheel 1 and press the limit switch thereby cutting off the complete power supply. The standby wheel 9 protects the further malfunction of the flywheel power generation equipment. Air filled tires or solid rubber tires will be used for standby wheel 9 and tire wheel 2 and the surface of Path 8 will be roughened for tire grip.

[0036] According to the present invention, overload relay is installed on each motor, wherein the said overload relay helps in protecting the said flywheel power generation system. The overload relay are installed on the motor wherein when any motor relay trips due to any reason, then the entire power supply will be cut off. Additionally, no-load current relay is installed on each motor due to which if the amount of air in the tire wheel 2 is low, the said tire wheel 2 does not touch the path 8, due to which the motor will consume less current and no-load current relay will tripped, and the entire power supply is cut off. Also, brakes can be applied to tire wheel 2 or motor 7, but the tension of the said brakes should be low enough to avoid jerking of the flywheel 1.

[0037] Figure 7 is the exploded view of the flywheel 1. With reference to Figure 7, Figures 7A, 7B, 7C and 7D of the flywheel 1 are more than one separate parts and the central assembly 46 is disclosed. The four parts of the flywheel are numbered 30 to 31, 32 to 33, 34 to 35 to 36 to 37 where enough nuts and bolts are used to connect them. In this way the joints 38 and 39; 40 and 41; 42 and 43; and 44 and 45 will be connected with nuts and bolts. Also, the joints 38 to 45 will be attached to the central assembly 46. The complete weight of the flywheel 1 with central assembly will be on the tire wheel 2 adjoining the circumference of the said flywheel 1. The weight of Flywheel 1 will be increased or decreased as per the requirement.

[0038] Figure 8 is an exploded view of the vertical shaft, central flywheel assembly and steel metal base assembly. In reference to Figure 8, the central assembly 46 and the steel metal foundation assembly 10 are exposed, with the outer part of the vertical shaft 11 splined onto the 47 and the inner part of the center assembly hole 67 splined up, so that the flywheel 1 slides smoothly up and down. The base plate 25 is attached to the steel metal foundation assembly 10 by welding, the base plate 25 will be attached to the slab with foundation bolts. Steel metal base assembly 10 is made in a circular shape and a hole are made in the base plate. Multiple bearing housings 48 and 49 are made in the metal base assembly, in which bearings 50 and 51 will be fixed. There is more than one bearing sizes on the outer side of the vertical shaft assembly, on top of which bearing 50 and bearing 51 will be fixed. Bearing 50 and bearing 51 are spaced sufficiently so that the flywheel assembly does not tilt and there is sufficient gap between the bearing housing and bearing so that the flywheel assembly can slide up and down smoothly. More than one bearing, housing and bearing size is used.

[0039] According to the present invention more than one step is made in the housing at a sufficient distance to prevent the bearing. The central assembly 46 is fixed into the metal base assembly 10, and one end of the vertical shaft 11 will be fixed to the hole and spline 67 of the central assembly 46, and the other end of the vertical shaft 11 will pass through the metal base assembly hole 68 and slab hole 28 and connects to the incoming shaft of a right angel gearbox installed in the basement. When all tire wheel 2 is short of air, the bearing housing and shaft 11 in the spline 67 slide up and down smoothly, and one tire Wheel 2 loses air or, if the tire is punctured, the flywheel 1 does not bend to one side because the bearing is fixed at a sufficient distance. Flywheel l's balance load is applied to more than one bearing and the flywheel is prevented from bending.

[0040] Figure 9 is the exploded view of the freewheel 4. With reference to Figure 9, the freewheel 4 assembly includes oil seal 54, spring housing 55, spring 56, spline 57, outgoing side gear 58, incoming side gear 59, incoming gear spline 60, housing 61, oil seal 62. When the incoming side gear 59 is rotated, it locks the outgoing side gear 58 which will rotate the outgoing side gear 58 and by rotating the tire wheel 2, the flywheel 1 will continue to rotate. If for some reason the incoming side gear 59 does not rotate, the outgoing gear 58 will continue to rotate due to the flywheel 1 being in motion. But the outgoing side gear 58 will slip from the incoming side gear 59 so that the speed impact of the flywheel 1 will not fall on the gear box 5. There will be a bearing in the housing of the outgoing direction of freewheel but the housing of the incoming direction of freewheel will be fixed with a knob. The above mentioned freewheel is worked same as cycle freewheel.

[0041] According to the present invention, the freewheel assembly 4 will be attached to the lock key on the step provided on both the shafts, the head clip and both the housing 55 and 61 will be attached through the nuts and bolts with both oil seals 54 and 62. Wherever oil seals, oil, grease, bearings are required, the said things will be used. Alternatively, clutch can be installed in place of freewheel 4.

[0042] Figure 10 is the exploded view of the central flywheel assembly and the vertical shaft of the flywheel 1. With reference to Figure 10, the vertical shaft 11 has a splined section 47 which passes through the hole splined 67 of the central assembly 46. There is sufficient gap between both splines for sliding it.

[0043] Figure 11 is the side view of the underground assembly of the flywheel disclosing the vertical flywheel. The assembly of Figure 11 discloses the additional freewheel 63, first vertical flywheel 64, coupling 65 and second vertical flywheel 66. By installing additional two vertical flywheels 64 and 66, the storage of energy will increase, so that more power can be generated by adding a higher capacity alternator. If for any reason the power supply to the flywheel 1 is cut off or disconnected, the vertical flywheel 64 and 66 will continue to rotate due to speed imparted in them. Therefore, the horizontal flywheel 1 will continue to be in motion due to speed of vertical flywheel 64 and 66. To avoid the malfunctioning in flywheel electricity generation device, an additional freewheel 63 is installed. This freewheel working same as cycle freewheel. And clutch can be used instead of freewheel.

[0044] The length, width, height, thickness and capacity of all parts and tools involved in the present invention will be adjusted by either reducing or increasing according to the requirement.

Detail description of the invention

[0045] According to the present invention, the technical solution adapted herein includes more than one part (7 A, 7B, 7C, 7D and 46) of the flywheel. The more than one circumferential direction part end of the flywheel are connected to each other by nut bolts and the other ends of the flywheel parts are connected to the central assembly. Flywheel 1 is designed to be installed horizontally and multiple drive assemblies equidistant on the top surface of the flywheel in a circumferential direction. The shaft of tire wheel 2 passes through more than one bearing which is connected by freewheel 4 to the outgoing shaft 5 of the step-down gear box and the incoming shaft of the step-down gear box 5 is connected to the motor shaft by coupling, hole 28 is made in the top surface of slab 18 and hole 68 is made in metal base plate 25 and the steel metal base assembly is installed on the slab by foundation bolts. The metal foundation 10 is made in a circular shape, with the smaller bearing housing 48 and the larger bearing housing 49 and the housing having enough steps to stop both bearings. The small bearing 50 and the large bearing 51 are fixed to the outer part of the central assembly 46 to the bearing sizes 52 and 53. If the air in all the tires wheel 2 is reduced, bearing can easily slide up and down in the housing, and the standby wheel 9 will touch the path 27 and take the load of flywheel 1, and due to press the limit switch by standby wheel the entire power supply will be cut off. If one tire is short of air or the tire is punctured, the flywheel does not tilt to one side, because there is sufficient distance between the more than one bearings. The weight of the flywheel being balanced on both bearings will prevent the flywheel from bending. In such cases more than one bearing shall be used. The electric busbar is installed on the foundation plate or on the concrete slab surface under flywheel 1 and the friction connector attached to the said flywheel 1 continues to rotate with flywheel 1 by touching the busbar, which supplies power to the motor. The number of busbars and friction connectors will be increased as per the requirement.

[0046] Tire wheel 2 is installed vertically and at right angles to the circumference of flywheel 1 so that tire wheel 2 can move freely along with path 8. And the standby wheel 9 is installed below the flywheel 1 and parallel to the tire 2, and the standby wheel 9 is installed at a sufficient distance from the surface of the path 27. Meaning standby wheel 9 does not touch path 27. If air in the all tire 2 is reduced, Flywheel l's load will be transferred to Standby Wheel 9, and Standby Wheel 9 will press the limit switch on Path 27, thereby turning off the entire power supply. In addition, the said standby wheel 9 will prevent further damage to power generation equipment. If the power supply is disconnected for any reason, flywheel 1 will continue to rotate from being in motion and will rotate the drive assembly, so freewheel 4 is installed to avoid this. Concrete slab 18 and basement is made of cement concrete. On the top surface of the said concrete slab 18 which is circular in shape, two paths of sufficient height and width are adjacent to each other in which one path is tire wheel path 8 and the other path is standby wheel path 27. More than one limit switch is installed at sufficient distance on standby wheel path 27. Which is used to cut off the entire power supply. [0047] The flywheel assembly described in the present invention is installed horizontally over a concrete slab 18 with a steel metal foundation assembly and the generator assembly is installed in the basement. The motor is AC or DC, and one end of the cable is connected to the AC or DC drive, the other end of the cable is connected to the busbar. The top surface of the busbar is in relation to the friction connector. The end of the other cable is connected to the friction connector and the other end to the motor. Power will be supplied to the motor from AC or DC VFD through cables, busbars and friction connectors. When the power supply is charged, it will rotate the drive assembly tire, which rotates the flywheel by the circumference of the flywheel, where the flywheel central assembly rotates the generator assembly by a vertical shaft.

[0048] According to the present invention, the technical solution adapted here achieves higher torque and generates more power by rotating the flywheel from the periphery of the flywheel by the drive assembly and the generator assembly by the central assembly of the flywheel.

[0049] According to the present invention, additional friction connectors shall be installed in parallel to avoid supply disconnection.

There are several advantages of the present invention

[0050] The primary advantage of the present invention is that the flywheel electricity generation device enables to achieve high power output.

[0051] Another advantage of the present invention is that, as the flywheel is constructed using multiple parts, it makes it easier to dismantle, transfer, load and unload the flywheel.

[0052] Yet another advantage of the present invention is that, the flywheel electricity generation device is achieve high torque from less force by rotating the flywheel from the extreme end of the flywheel, which also uses the flywheel storage energy to rotate the flywheel. [0053] Yet another advantage of the present invention is that, the electricity it is generated at low cost.

[0054] Yet another advantage of the present invention is that, the diameter of the flywheel is adjusted accordingly where it is reduced or increased as per requirements.

[0055] Yet another advantage of the present invention is that, the flywheel electricity generation device does not require heavy structural components and it is easily assembled and disassembled, making it easy for transportation.

[0056] Example for working calculations: Alternator RPM = 1500

Each Motor RPM = 1500

Step Up Gear Box Ratio = 1 : 100

Each step-down Gear Box Ratio = 5.26: 1

Each tire wheel perimeter (meter) = 1

Flywheel Perimeter (meter) = 19

If the ratio of step-up gear box is 1 : 100, then for 1500 RPM, the gear box has to be rotated 15 times in the incoming direction.

If the gear box is to be rotated 15 times, the flywheel has to be rotated 15 times. The perimeter of the flywheel is 19 meters.

Therefore, 15*19 = 285 meters/min.

Step Down Gear Box Ratio = 1500/285 = 5.26 RPM

If the circumference of the tire wheel is 1 meter, the tire wheel has to be rotated 285 times in 1 minute, then accordingly, rotating a motor 5.26/1 gear box of 1500 RPM will rotate the output squad of the gear box 285 times in a minute.

Therefore, the tire wheel of 1 meter circumference will rotate 285 times in a minute.

If the flywheel rotates the input shaft of the step-up gear box 15 times, the output of the gear box will rotate 1500 times. If the output squad of the gear box rotates 1500 times, the alternator/generator will rotate 1500 times in a minute.

*Note: Reducing or increasing the perimeter of the flywheel may vary the assessment.
