The principle of power generation is that the turbine can rotate in seawater, whether in parallel flow or in countercurrent flow. The turbine drives the chain through the transmission shaft, then drives the gearbox through the chain, and then drives the generator to generate electricity through the gearbox, so that kinetic energy is converted into electric energy, and grid-connected power transmission is performed through the voltage stabilizing and transforming device. The number of blades of the turbine can be 2 to 10, and the number of blades can be selected according to different water flow speeds of different regions. The straight-face forward flow or reverse flow of the turbine blades is 25-39 degrees, and the turbine naturally rotates when water flows.
The equipment is fixed on the seabed, the turbine is arranged in flowing seawater, and the front surface of the turbine is vertical to the flowing water direction, so that the flowing seawater can drive the blades to drive the generator to generate electricity. The rotating speed of the turbine is determined according to the speed of the ocean water flow, the power is generated through the speed changing box from 1 r/min, and the power is generated more at the faster rotating speed.
The above patent has a good effect, however, the ocean tide has the rise and the fall, rise and fall promptly, fall and rise promptly, the biggest difficult problem of tidal power generation is that the flow rate is from slow to fast, from fast to slow, once a day, once a night, the rotational speed of the hydraulic turbine is also from slow to fast from fast to slow, when turning fast greatly, the power is very little again, therefore, the power-generating incoming voltage is very unstable, and the distribution ball of the water turbine is also very difficult to be distributed, when the rotational speed of the hydraulic turbine is very big at the flow rate and the rotational speed of the hydraulic turbine is little if the power is distributed to the ball, the ball does not use its energy, will cause partial energy waste, if the power is distributed to a little, the hydraulic turbine does not drag the power ball again when the flow rate is slow, drag not the power ball to generate electricity and also waste partial energy
