Abstract

PROBLEM TO BE SOLVED: To stably supply electric power at a low cost and in a simple structure without giving bad influence to the environment, by grabbing energy of pressure of speed force of a fluid which moves in a sealed space using a rotating fin and by extracting it as electric energy by rotating a generator using the energy of a fluid pressure of speed. SOLUTION: A fluid tube 1 consists of large diameter parts 2a, 2b with the same diameter as other fluid tubes connecting back or forth of the fluid tube 1, taper parts 3a, 3b, whose tube diameter gradually decreases from the large diameter parts 2a, 2b toward the intermediate part of the fluid tube 1, and a small diameter throttling part 4 which is placed at the intermediate part of the fluid tube 1. The taper parts 3a, 3b are formed only on the bottom and the side of the fluid tube 1, the top of the fluid tube 1 is on the same plane. A rotating fin 5 is placed on the top of the throttling part 4. Because the throttling part 4 throttles the cross section of a flowing passage, the speed of the fluid passing through the throttling 4 increases, and the fluid pressure increases. Therefore, the rotating fin 5 can be efficiently rotated.

FIG. 1 is a front view of an embodiment of a fluid power generation device according to the present invention. FIG. 2 is a plan view showing an embodiment of the fluid power generation device of the present invention together with a control panel and a storage battery.

The fluid pipe 1 has large diameter portions 2a, 2b having substantially the same diameter as other fluid pipes connected before and after the fluid pipe 1.
And tapered portions 3a, 3b whose diameters gradually decrease from the large-diameter portions 2a, 2b toward the middle portion of the fluid pipe 1, and a small-diameter throttle portion 4 located at the middle portion of the fluid pipe 1. Have been. At both ends of the fluid pipe 1, flanges 1a, which are used to connect the fluid pipe 1 to front and rear connection pipes,
1b is formed.

The tapered portions 3a and 3b are formed only on the lower surface and side surfaces of the fluid pipe 1, and the upper face of the fluid pipe 1 is flush. The fluid pipe 1 is disposed in a pipe for transporting a fluid such as a liquid or a gas disposed in an office or a factory, for example, in the course of a water distribution pipe or a gas pipe, in place of a normal pipe. .

A plurality of throttle portions 4 may be provided in one fluid pipe 1. Further, a plurality of fluid pipes 1 may be provided in the course of the water distribution pipe or the gas pipe.

An opening for rotatably disposing the rotary fin 5 is formed on the upper surface of the throttle 4 of the fluid pipe 1. The rotary fin 5 includes an annular mounting member 8 mounted on a rotating shaft 7 of a generator 6 and a plurality of blades 9 radially mounted around the mounting member 8.

The rotating shaft 6 of the rotating fin 5 is connected to the fluid pipe 1.
The rotatable fins 5 are rotatably supported at substantially the same height as the upper surface of the rotating fins 5, and the upper half of the rotating fins 5 is covered by a semicircular cover 10. The cover 10 is fixed to the upper surface of the fluid pipe 1 in a liquid-tight manner by screws, rivets, welding, or the like.

The generator 6 with the rotating fins 5 attached to the rotating shaft 7 is fixed to the pedestal 11 by bolts or the like. The output voltage of, for example, three-phase alternating current from the generator 6 is
It is supplied to the control panel 12 and converted into a DC voltage.
The DC output voltage is stabilized as required. Control panel 12

In the fluid power generation apparatus shown in FIGS. 1 and 2, a fluid pipe 1 is usually provided in a pipe for transporting a fluid, such as a water pipe or a gas pipe, which is disposed in an office or a factory. It is arranged in place of the piping. In the figure, the fluid flowing from the right side of the fluid pipe 1 first passes through the large-diameter portion 2a, and then the cross-sectional area of the flow path is narrowed at the tapered portion 3a to reach the small-diameter throttle portion 4, where the rotary fin is rotated. The rotating fins 5 are rotated while hitting the lower half blades 9 of the rotating blades 5. At this time, since the cross-sectional area of the flow path is narrowed, the speed of the fluid passing through the throttle unit 4 increases, and the fluid pressure increases. Thereby, the rotating fin 5 can be efficiently rotated.

Since it is desirable that the velocity of the fluid flowing through the fluid pipe 1 be substantially constant, the fluid pipe 1 is arranged in a flow path in which the consumption of water or gas per unit time is substantially constant. It is desirable, but not limited to this. For example, the fluid pipe 1 may be arranged in the middle of a water pipe or a gas pipe for general consumers. In this case, the amount of power generation changes because the fluid in the fluid pipe 1 flows at an undefined pressure or speed. However, a stabilizing device is used, or power from a plurality of generators is appropriately combined. Thus, power can be supplied stably.

According to an experiment, the diameter of the fluid pipe 1 is 600 m.
