Description

Description Pipe power generator Technical field

The present invention relates to a hydroelectric power generation device that can be attached to water and sewage pipes and various fluid pipes indoors and outdoors, and a structure that enables efficient power generation by utilizing the water pressure and water flow in the pipe, and a structure that is easy to replace with a structure that is easy to attach. The present invention relates to a pipe power generation apparatus having a plurality of pipe power generation apparatuses in series and in parallel depending on water pressure levels in water pipes and various fluid pipes. Background art

Conventional hydroelectric generators that can be attached to indoor and outdoor water and sewage pipes and various fluid pipes have been developed for a long time.For example, a generator is installed at the intake of water and sewage in homes and offices, Japanese Patent Application Laid-Open No. 57-8367, which is an idea to save city electric power by driving a generator using hydraulic power, was known as a power generation method using tap water. It was pointed out that the conditions for installing generators were difficult to construct and difficult to install multiple generators.

Furthermore, the idea of conserving electricity by driving the evening bin generator using the water pressure and water flow of the water supply and sewerage system is the idea of saving electricity by the water supply system published in Japanese Patent Publication No. 57-288776. Japanese Patent Laid-Open No. 59-21 is an idea to economically generate electricity by saving electricity and installing a small hydroelectric generator in the water pipe to drive the generator using the flow of high pressure water. The small hydroelectric generator disclosed in Japanese Patent No. 59698 has a problem that the power generation efficiency is never high. In addition, by installing a small generator at the nozzle of the fire hose or at the faucet of a general water supply system, Japan is an idea that can be used for water-proofing and discharge of small-scale power generation, which was not used before. It has been pointed out that the generator of Japanese Patent Application Laid-Open No. 63-151,7979 seems to have good workability, but there is a problem with the efficiency and economy of the generator.

In addition, Japanese Patent Application Laid-Open Publication No. 2004-115,1972 discloses an idea of connecting a plurality of hydroelectric generators along a water supply pipe and providing a bypass pipe in each of the hydroelectric generators so that the hydraulic power generator can be repaired without interrupting the water supply pipe. In the power generation equipment published in the public announcement of No. 1986-1986, it seems to be an advantageous idea for repair, inspection and replacement. However, installing bypass pipes in each hydroelectric power generation equipment is a costly production of the power generation equipment. It has been pointed out that the rise is inevitable, and that this is the reason why the spread of this power plant has been delayed.

Due to the above-mentioned problems, the present invention provides a power generation device with excellent workability at the site, which has a structure capable of efficiently generating electricity and has a structure that can be easily replaced, and a water pressure in water and sewage pipes and various fluid pipes. It is an object of the present invention to provide a pipe power generator characterized in that it can handle a plurality of connections depending on the level. Disclosure of the invention

The pipe power generation device of the present invention is a hydraulic power generation device attached to water and sewage pipes and various fluid pipes indoors and outdoors. The water flow conforms to the shape of the rotating fan provided, and the water guide section is provided so that the water pressure is equal to that of the rotating fan. The cross section of the water flow and water pressure in the pipe becomes the shape of the rotating fan by passing through the water guiding section, which has become the shape of the rotating fan, so that the water pressure in the pipe uniformly hits the surface area of the rotating fan Power can be generated efficiently.

Further, the present invention provides the pipe power generator, wherein installation work for water and sewage pipes and various fluid pipes indoors and outdoors is troublesome, and the pipe power generator is, for example, a failure of a rotating shaft, a breakage of a rotating fan, and In order to maintain a smooth replacement structure for maintenance, installation parts were provided for the headrace section and the drainage section, respectively.

Further, the present invention provides the pipe power generator, wherein a plurality of connections are made possible by providing a mounting portion for each of the water introduction section and the drainage section, thereby enabling water pressure and water flow levels in the water and sewage pipes and various fluid pipes. Power generation can be performed efficiently and economically by using water in the water supply and sewage and various fluid pipes. BRIEF DESCRIPTION OF THE FIGURES

FIG. 2 is a partially cutaway sectional view showing one embodiment of the pipe power generator according to the present invention.

FIG. 3 is a partially cutaway sectional view showing one embodiment of the pipe power generator according to the present invention. BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be described in more detail with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the pipe power generator of the present invention is composed of a pipe power generator 10, a rotary fan 20, a mounting part 30, a pipe joint PJ, and a generator 40. I have.

This pipe generator 10 is composed of an oil seal 11 and a ball bearing. It is composed of a bolt hole 13 and a water guide section CW and a drain section D that match the shape of the rotating fan.If the body is made of plastic, for example, plastic is used. The fan 20 is provided with a generator shaft, and if the main body is made of plastic, for example, plastic is used. Injection molding is mainly performed using a mold. If water and sewage pipes used inside and outside are plastic pipes, for example, consider compatibility with commercially available plastic pipe joints PJ. It is mainly injection-molded using a mold.

After assembling the commercially available ball bearings 12 and oil seals 11 into the pipe power generator 10 molded as described above, the rotary fan 20 is set, and the pipe power generator 10 is completed. .
