Using the renewable ocean tide to generate power, the tide power generation device is clean, stable and reliable, emits less carbon and can not affect the ecological balance.

Description

[0001] professional field [0002] The present invention relates to a power generation device, more specifically, to a tidal power generation device which utilizes ocean tidal energy to generate power. Background technique [0003] With the development of science and technology, human beings have an increasing demand for energy, and the exploitation and use of fossil energy such as oil, natural gas, and coal will bring huge damage and pollution to the environment. In addition, this type of fossil energy belongs to Non-renewable energy, due to continuous consumption, is increasingly facing exhaustion, so it is imminent to find clean, pollution-free and renewable alternative energy. [0004] The tidal phenomenon is caused by the change of the moon's gravitational force, and the tide causes the sea level to rise and fall periodically. The energy generated by the fluctuation of seawater and the flow of tidal water becomes tidal energy. Power generation has the advantages of being...

AI Technical Summary

Problems solved by technology

[0006] 1. The tidal power station is built in the mouth of the harbor, usually the water depth is long, the construction, foundation treatment and silting prevention are difficult, and the civil engineering and electromechanical investment are large and the cost is high;

[0007] 2. The generating units of tidal power stations usually use hydraulic turbine units. Since tidal power stations are low-head and large-flow power generation methods, the turbines are huge in size, consume a lot of steel, and the structures of the buildings entering and leaving the water are complex, resulting in high costs for the power station; and Because most of the structure of the hydraulic turbine unit needs to be immersed in seawater, seawater and marine organisms have a corrosive effect on metal structures and marine structures. Due to the complex structure of the generator set and marine structures, it is difficult to clean and maintain, and special treatment is required , further driving up the cost of
