Abstract

PURPOSE:To save a series of public work, which necessitates an enormous building cost, remarkably and permit to build the miniature hydraulic power plant of low power generating cost by a method wherein the pipeline, newly built or already built for other purposes, is utilized to generate electric power by intaking water through bypass pipe connected to the pipeline at any desired place. CONSTITUTION:The electric power is generated by driving water turbine generator 3, such as a tubular generator, an integral type generator or the like, installed so as to be accompanied by the principal pipeline 1 provided with a natural head from the dam of city-water, water for generating electric power, a river or the like through the bypass pipe 2 connected to the pipeline 1 at any desired place. One part of the principal pipeline 1 is formed by a smaller diameter pipe 5 in order to branch the bypass pipe 2 at any place and introduce the amount of water necessary for the water turbine generator 3 into the bypass pipe 2. According to this method, the miniature hydraulic power plant of low power generating cost may be built without necessitating enormous amount of building cost.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for generating electricity by installing bypass pipes at various locations in a pipeline having a water head and taking in water.

Conventional hydroelectric power plants require a series of civil engineering facilities that require huge construction costs, such as dedicated water intake dams, water intake equipment, settling basins, headrace channels, water tanks, and penstocks.
The development of mini-hydroelectric power generation in the class of less than KW has become extremely expensive due to the above-mentioned pressure on civil engineering equipment costs, making practical development impossible.

On the other hand, in order to develop oil-alternative energy, it is necessary to make full use of the precious hydropower resources endowed 4 and develop mini-hydroelectric power generation as mentioned above.

This invention utilizes existing or newly constructed pipelines for other purposes and connects bypass pipes at various locations to extract water and generate electricity, thereby significantly reducing the above-mentioned series of civil engineering facilities that require huge construction costs. In short, the purpose is to construct a mini-hydroelectric power plant with low power generation costs.

This invention will be explained as follows based on the drawings.

As shown in Figure 1, a tubular generator or a
Hydrogen generators 3 such as body type generators are installed at various locations using bypass pipes 2 to generate electricity from water. Furthermore, when main power generation is to be performed at the end of the main pipeline 1, secondary power generation is performed at various locations along the pipeline 1, and the number of electric wires from the main power plant 4 to the nearest power load equipment is reduced.

As shown in Fig. 2, the bypass pipe 2 is branched at various points on the main pipeline 1, and in order to introduce the amount of water required by the water turbine generator 3 into the bypass pipe 2, a part of the main pipeline 1 is connected to a medium-thin pipe. 5.

[Brief explanation of drawings]

Figure 1 shows the main pipeline, which takes water from a dam or river headwork and transmits it via natural pressure to its destination over a short distance.Bypass pipes are installed at various points near the points where electricity is needed for power generation. It is a drawing showing a device that divides the amount of water and partially operates a water turbine generator. FIG. 2 is a drawing showing an apparatus for introducing the amount of water required for power generation into a bypass pipe using a medium-sized pipe in a main pipeline. 1... Main pipeline, 2...
