Sea tidal power generation device

Abstract

The invention discloses a sea tidal power generation device comprising a reservoir and a generator unit; the water level of the reservoir is higher than the sea plane; the reservoir is provided with a water supplying device utilizing tiding to convey sea water to the reservoir; the water supplying device comprises uprights, a pump body lower cylinder, a float assembly and a water pipeline; the pump body lower cylinder is positioned among the uprights; the float assembly is positioned above the pump body lower cylinder; during ebb tide, the lower part of the float assembly and the upper part of the pump body lower cylinder form piston sealing match; one end of the water pipeline is communicated with the lower part of a fixing water pipeline; and the other end of the water pipeline extends to the reservoir. The sea tidal power generation device adopting such a structure can utilize tidal energy to store the sea water in the reservoir higher than the sea level, and can continuously generate power.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to an ocean tidal power generation device. Background technique [0002] Changes in the moon's gravitational force will cause tidal phenomena, and the tides will cause the sea level to rise and fall periodically. The energy generated by the ebb and flow of seawater and seawater flow is called tidal energy. At present, there are two operating modes for tidal power generation. The first one is a single-reservoir single-pass tidal power station, which allows seawater to enter the reservoir during high tide, and uses the tidal difference between the reservoir and the sea to drive the hydroelectric generator set during ebb tide. It cannot generate electricity continuously. Send electricity once when the tide is low. The second type is a single-reservoir dual-stage tidal power station, which uses the special design of the reservoir and the function of the sluice to generate elec...

AI Technical Summary

Problems solved by technology

The second type is a single-reservoir dual-stage tidal power station, which uses the special design of the reservoir and the function of the sluice to generate electricity at high tide and run at ebb tide, but cannot generate electricity when the water levels inside and outside the reservoir are the same and the tide is flat. Generating electricity twice when the tide rises and falls. Compared with the former, it can greatly improve the utilization rate of tidal energy. Because it cannot generate electricity continuously, it also has limitations.
