Abstract
Description
[Technical Field]
[0001] By generating electricity using natural water flows and wastewater from businesses, etc., and using the electricity generated appropriately, we can help save energy. [Background technology]
[0002] We wondered if it would be possible to generate electricity using small hydroelectric generators that utilize natural water flows such as rivers and streams in mountainous areas, or wastewater from factories and businesses, and use the electricity generated as a power source for various locations.
[0003] The system diagram below (Figure 1) shows how small-scale hydroelectric power generation utilizes water, a resource that is usually overlooked. [Brief explanation of the drawings]
[0004] [Figure 1] When water is pumped from the water supply (1) to the water tank (2), it flows out of the drain outlet at the bottom of the tank and falls, turning the power-generating water turbine installed in the drain pipe.
[0005] The rotation of the generating water turbine turns generator A, generating 12V of electricity.
[0006] 12V electricity is stored in a battery and then sent to a transformer, where it is converted from 12V to 100V.
[0007] A 0.5 HP motor C is powered by a 100V power supply and turns a 20 kg flywheel D.
[0008] The rotational force of the flywheel D drives a generator E, which drives a 1 HP motor F.
[0009] The 1HP motor rotates a 200kg flywheel G.
[0010] The rotational force of the 200 kg flywheel drives generator H.
[0011] The electricity generated by generator H is sent to capacitor I.
[0012] The electricity stored in the capacitor I is distributed to the intended use.
Claims
[Claim] Water from rivers with a difference in water flow, spring water, or wastewater from factories and businesses is used to turn a water wheel, and the torque is transmitted to generator A to generate 12V electricity. The 12V power supply is converted to 100V using transformer B. A 100V power supply is used to rotate a 0.5HP motor C, which turns a flywheel D weighing 20kg. The rotational force of this motor C turns a generator E, and the resulting electrical power rotates a 1HP motor F. The torque of the motor rotates a flywheel G weighing 200 kg to operate a generator H, and the obtained electricity is stored in a capacitor I and distributed to the intended use.
