No. 7 is proposed. Both of the above-mentioned two inventions generate rainwater by rotating rain turbines by dropping rainwater, but they have the following problems and are not suitable for practical use.

右され、常時一定の発電量を得ることはできない。The invention of Japanese Patent Application Laid-Open No. 60-62351 has a main purpose of discharging rainwater in a building, and intends to utilize the discharged rainwater for power generation. Therefore, the rainwater that flows down from the roof and is once used to rotate the water turbine is directly discharged by the discharge pump. Therefore, power cannot be generated when there is no rainfall, and the amount of power generation decreases when the amount of rainfall is small. For example, the amount of power generation depends on the amount of rainfall, and it is not possible to always obtain a constant amount of power generation.

左右され、常時一定の発電量を得ることはできない。The invention of Japanese Patent Application Laid-Open No. 8-237997 is to rotate rainwater by causing rainwater to be stored in a storage tank and then flow down. By storing rainwater in the storage tank, it is possible to control the amount of rainwater that flows down, but the rainwater that has once flowed down is discharged as it is, as in the above-described invention. Therefore, also in this invention, the amount of power generation depends on the amount of rainfall, and a constant amount of power generation cannot always be obtained.

念図であり、建物１の屋根SUMMARY OF THE INVENTION A rainwater power generator according to the present invention comprises a rainwater storage tank, a generator in which a water turbine is rotated by potential energy of rainwater, an electric pump for pumping rainwater, and an electric pump for driving the electric pump. The above problem is solved by a rainwater storage tank, a generator, and an electric pump that are connected by pipes so that rainwater can circulate. The rain water storage tank, the generator, and the electric pump may be connected in various orders. It is preferable that the rainwater storage tank is installed on a horizontal plane so that rainwater is pumped up to the roof of a building and dropped (claim 2). FIG. 1 is a conceptual diagram of the present invention, which is a roof of a building 1.

けるエネルギー損失は考慮する必要がない。In the present invention, when the rainwater flows down, the water wheel of the generator rotates to obtain electric power. Then, the rainwater that has rotated the water turbine is pumped by the electric pump and flows down again to rotate the water wheel. That is, since rainwater is circulated and used, a constant amount of electric power can always be obtained even if there is no rainfall. Since the electric pump is driven by the electric power obtained by the solar generator, it is not necessary to consider the energy loss in pumping rainwater.
