A power generator system FIELD OF INVENTION

This invention relates to a power generator system. The system in a water body is employed for generation of rotational energy to produce electricity.

BACKGROUND AND PRIOR ART

Presently, hydro power generation system makes utilization of falling water to rotate turbines for rotational energy. The rotational energy is used to produce electricity. However it is only about 10 to 15% efficient. Further, huge infrastructure like large dams are required to be built to obtain power from this kind of system.

Hence, there is a requirement to develop a system for generation of rotational energy to produce electricity, which can function efficiently without relying on the kinetic energy of water and also without requiring huge construction. Therefore, the present invention introduces a power generator system which involves buoyancy. The buoyancy or upthrust is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus, the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. This pressure difference results in a net upwards force on the object. The magnitude of that force exerted is proportional to that pressure difference, and an explained by Archimedes’ principle is equivalent to the weight of the fluid that would otherwise occupy the volume of the object, i.e. the displaced fluid.

For this reason, an object whose density is greater than that of the fluid in which it is submerged tends to sink. If the object is either less dense than the liquid or is shaped appropriately (as in a boat), the force can keep the object afloat. In a situation of fluid statics, the net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body.

The center of buoyancy of an object is the centroid of the displaced volume of fluid.

Archimades’ principle states that-

Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. In simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g.

OBJECTS OF THE INVENTION

Primary object of the present invention is to provide a power generator system which obviates drawbacks associated with the prior art.

Another object of the present invention is to provide a power generator system which is pollution free and easy to operate.

Yet another object of the present invention is to provide a power generator system which is efficient. Still another object of the present invention is to provide a power generator system which is compact.

SUMMARY OF INVENTION

According to this invention there is provided a power generator system comprising of atleast two containers connected by a connecting means resting on pulley, wherein said container of cylindrical assembly includes outer cylinder accommodating movable and stationary cylinder.

TO THE ACCOMPANYING DRAWINGS

The present invention is pertinent to a technology relating to a power generator system to generate rotational energy for production of electricity using the rotational movement.

The power generator system comprising of two containers connected by a connecting means such as rope/belt/chain resting on a pulley such that one container on one side is below another container on other side of said pulley during operation of the system.

The containers constitute hollow containers for filling liquid /vacuum thereinside. Once the liquid filled container is immersed in liquid due to gravity, the liquid in the container is replaced by means of vacuum with the help of motor to render the container lighter causing upward movement of the container inside water.

Thereafter, another container filled with liquid gets immersed down in the liquid occupying a lower position so as to balance with the other container. Subsequently the liquid inside is substituted by vacuum to make it lighter, so that it will also move up. The container can be provided with a pump/valve. The system can be operated in open well/lake/sea. The whole operation can be automated. Thus, the up/down movement of the containers leads to rotation of pulleys thereby generating rotational energy, which can be utilized to produce electricity for various purposes by establishing connectivity of the pulley system with an alternator.

The above can be detailed out hereinunder, wherein both the containers have same configuration, hence one is described hereinbelow.

Now, reference may be made to fig. 1 and 2, wherein said power generator system comprises a plurality of cylinders including outer cylinder (1) accommodating movable (2) and stationary cylinder (3). The outer cylinder constituting a hollow cylinder covered from top is connected to a water inlet/outlet (4) at top and an annular member (5) at base thereof. Said annular member is having multitude of holes (6A) therealong as shown.

The movable cylinder (2) forming a hollow cylinder, top of which is fixedly secured to a plate (7) holding a piston (8) at center thereof.

Said stationary cylinder (3) constituting a hollow cylinder, base of which is fixedly secured to a plate (9) having multiple openings (O) allowing passage/exit of water therethrough. Said openings are surrounded by multitude of holes (6B).

Further, there is provision of an oil inlet (I) at the center of the base plate (9) in flow communication with a hydraulic cylinder (10) placed thereabove within the stationary cylinder (3) as illustrated in the figure 2. An electric motor (Not shown) is connected to the inlet (I) for supplying oil to the hydraulic cylinder.

The stationary cylinder (3) is partially housed inside the movable cylinder (2) in the intermediate position of piston thereby creating a gap between outer surface of stationary cylinder and inner surface of outer cylinder. Water (W) is contained in the space(S) between the top plate (T) and middle plate (7) and also in the gap between the two cylinders. The annular ring (5) and base plate (9) are fastened to each other through the plurality of holes (6A and 6B).

Now, reference may be made to figure. 2A, 2B and 2C reflecting three positions of the piston, namely initial position, intermediate position and final position.

In the initial position, the piston rests on the base plate (9) and in the intermediate position, said piston is positioned between the base plate (9) and top plate (T). In the final position, the middle plate (7) establishes contact with the top plate (T) by expelling water (W) completely through the outlet (4).

As can be seen in figure 3, top ends of both the containers are connected to each other by means of chain (Ci) and bottom ends of which are connected with the help of chain and electric cable (C ₂ ). Both the electric motors are actuated by a switch available with the system of invention.

When one container of cylindrical assembly is immersed in water, water flows through the openings (O) so as to fill the space between outer surface of the stationery cylinder (3) and inner surface of the outer cylinder (1). This water in the gap exerts pressure on the wall of said movable cylinder (2). Further, the assembly of the middle plate, movable cylinder and piston moves together by hydraulic pressure caused due to hydraulic cylinder provided with the supply of oil through oil inlet/outlet(I).

Here, movement of the piston inside the hydraulic cylinder and in the space having water results in movement of the assembly of the middle plate, movable cylinder and piston causing discharge of water through the water outlet (4). Material of the system is such that density of the same is greater than that of water. The material includes Iron, Aluminium, wherein same or different materials can be used for different parts of the container.

Eventually, water will be displaced so as to fill the space (S') by vacuum. This leads to reduction in weight of the container causing it to go up. In order to maintain balance, the connected container on the other side is brought down by gravity causing rotational movement of the pulleys (P) supporting the containers. This rotational movement finally leads to production of electricity with the help of alternator (A)/turbine as illustrated in fig. 3.

Here, electricity production is directly proportional to depth of water.

The rotational movement generated by the system of present invention can be put to use for various purposes in industry. Thus, the invention has wider industrial application.
