The present invention relates to a hydroelectric power generation device, particularly a hydroelectric power generation device for operating a power generation device using the water flow of a water supply to obtain electric power.

Conventionally, various hydroelectric power generation devices for obtaining electric power by rotating a power generation device, particularly a water turbine, by using the water flow of the water supply described above and performing a power generation action by the rotation have been exhibited. However, it is less popular than solar power generation and some wind power generation, and the devices that have been exhibited in the past have poor practicability.

In addition, when power is generated using the water flow of the water supply, rotational movement is basic, but in the case of a water turbine, sufficient rotational force is rarely obtained due to the relationship with the water flow pressure, and the amount of power generation is poor. It ends up.

Furthermore, the obtained electric power is stored in a battery (storage battery) and used, but if this battery is also in a fixed position, the situation in which it can be used is specified, and its versatility is limited. It ends up.

The applicant searched the preceding technical literature for the invention of the present application, but could not find any literature that seems to be particularly related to or similar to the invention of the present application.

The problem to be solved by the present invention is that it is difficult to drastically change the structure of a conventional power generation device using tap water because it complies with various regulations. An impeller) is used, but that does not provide a sufficiently strong rotational force, and the amount of electricity that can be obtained must be reduced accordingly.

The rotation causes the brim-shaped protruding ring portion formed on the inner tubular tube to rotate in the ring-shaped hollow protruding portion formed on the outer tubular tube, and this rotation causes a power generation action. The electric power obtained by this is stored in the battery, but the electric power obtained by the powerful power that the inner cylinder itself rotates can be made larger than the conventional one.

In addition, since this hydroelectric power generation device is installed in the part of the water supply pipe that has passed through the meter, the relationship between the amount of water used and the obtained power can be clearly grasped, and the battery can be attached and detached. In the event of an unforeseen situation, the battery can be effectively used as various power sources.
