Description:
FLUID-DRIVEN GENERATOR

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to fluid-driven generators and more particularly to an electric generator driven by fluid such as wind, water or tides, the electric generator having improved guide device, deflection device, turbine and electric generation devices.

2. Description of Related Art

Tidal power is a form of hydropower that converts the energy obtained from tides into electricity. Tidal stream generators make use of the kinetic energy of moving water to power turbines, in a similar way to wind turbines that use wind to power turbines. However, there are a number of disadvantages associated with tidal power as below. Tidal Energy has an expensive initial cost. Low efficiency. Large land for installing tidal stream generators is required.

Thus, the need for improvement still exists.

Referring to FIGS. 1 to 7A, a fluid-driven generator 100 in accordance with a first preferred embodiment of the invention comprises a guide device 10, a deflection device 20, a turbine 30 and a plurality of electric generation devices 40 as discussed in detail below. It is noted that the fluid can be wind, water or tides and the fluid is wind in the first preferred embodiment.

The guide device 10 includes a guide member 11 having a plurality of joined rectangular guide plates 114, a first inlet 111 , an outlet 113, and a second inlet 112 between the first inlet and the outlet 113; a net 12 provided at the outlet 113 for preventing large particles or articles from passing through; and a flow accelerator 13 having an inlet 131 provided at the net 12 and a narrow outlet 132 distal the net 12. Thus, fluid may flow at an increased speed after leaving the outlet 132.

The deflection device 20 includes a parallelepiped housing 21 having an inlet 211 secured to the outlet 132 of the flow accelerator 13, and two opposite circular holes 213 through two sides 212 respectively; and a cylindrical deflection member 22 disposed in the housing 21 and having a plurality of equally spaced apart, inclined plates 221 on a periphery in which the deflection member 22 and the holes 213 are co-axial relative to an axis 214. The only exits of the deflection device 20 are the holes 213.

The turbine 30 includes two spaced rims 31 each having a plurality of drive gear 311 around, and an axle 312; and a plurality of equally spaced, curved blades 32 arranged between the rims 31 and adjacent to the drive gear 311.

The electric generation device 40 includes two opposite ring members 41 each having an annular member 412 secured to the side 212 and having an outer edge 411 , an annular flange 413 extending outward from an inner edge of the annular member 412, and a sleeve 414 disposed on an center and rotatably put on the axle 312; and three equally spaced electric generation units 42 provided on an outer surface of the annular member 412, each electric generation units 42 having a driven gear 421 on an inner surface of the annular member 412, the driven gear 421 meshing with the drive gear 311. As shown in FIG. 4, fluid 222 enters the deflection device 20 by way of a path from the first inlet 111 , the second inlet 112, the outlet 113, the net 12, the inlet 131 and the outlet 132. The flow rate of the fluid 222 is increased greatly by the flow accelerator 13. In the deflection device 20, the fluid 22 is divided into a plurality of fluid elements 223 by the inclined plates 221. The fluid elements 223 impinge the curved blades 32 in a predetermined angle to rotate the turbine 30. And in turn, the rotating turbine 30 in turn rotates the drive gear 311. Further, the driven gears 421 rotate to activate the electric generation units 42 which convert mechanical energy into electrical power.

In other embodiments, the guide plates 114 are arc-shaped or disc-shaped.

In other embodiments, the housing 21 are cylindrical.

In other embodiments, the net 12 is located at the outlet 132 of the flow accelerator 13.

In other embodiments, a sliding door (not shown) is provided in the inlet 211 for adjusting the flow rate and other purposes.

Referring to FIG. 8, a fluid-driven generator 100A in accordance with a second preferred embodiment of the invention is shown. The characteristics of the second preferred embodiment are substantially the same as that of the first preferred embodiment except the following: the housing 21 A of the deflection device 20A is provided with a plurality of holes each having an electric generation device 40 disposed therein.

Referring to FIG. 9, a fluid-driven generator 100B in accordance with a third preferred embodiment of the invention is shown. The characteristics of the third preferred embodiment are substantially the same as that of the first and second preferred embodiments except the following: the guide member 11 and the net 12 are not eliminated due to strong fluid flow.

Referring to FIG. 10, a fluid-driven generator 100C in accordance with a fourth preferred embodiment of the invention is shown. The characteristics of the fourth preferred embodiment are substantially the same as that of the first, second and third preferred embodiments except the following: the fluid is tides. Fluid 20 is guided from tides no more than 20 meters under sea level to the deflection device 20C above sea level. That is, the electric generation units are protected against sea water. A plurality of support posts 51 are mounted on the sea bed 50 with the deflection device 20 mounted thereon. A plurality of anchors 52 are mounted on the sea bed 50. A plurality of ropes 53 have one ends secured to the anchors 52 and the other ends secured to the inlet 131 C of the flow accelerator 13C. A frame 14 is mounted in the inlet 131 C for increasing structural strength of inlet 131 C.

While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
