Ocean tidal high and low level pump water energy storage power generation system

Abstract

The invention discloses an energy accumulation and power generation system by pumping water through oceanic tide high-low positions. The energy accumulation and power generation system comprises a seaborne reservoir, a hydroelectric generator, a plurality of supporting columns which are higher than the sea level, and a plurality of oceanic tide water pumping units for filling water into the seaborne reservoir, wherein the seaborne reservoir is located at the tops of the plurality of supporting columns; each oceanic tide water pumping unit comprises a fixed water cylinder, a floating body assembly which can move up and down, and a water pipe; the floating body assemblys are located above the fixed water cylinders; each floating body assembly is provided with a hollow floating box; a cavity of each floating box is provided with seawater for increasing the weight of the floating box at a falling tide. The energy accumulation and power generation system by the water of the oceanic tide high-low-pump disclosed by the invention adopts the structure that the seaborne reservoir is higher than the sea level, and the plurality of oceanic tide water pumping units for filling the water into the seaborne reservoir; when the position of the seaborne reservoir is higher, the potential energy is greater; and the oceanic tide water pumping units utilize a tide fall to fill the seawater into the seaborne reservoir which is higher than the sea level to continuously and stably generate power.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to an ocean tidal high and low pump water storage power generation system. 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 functio...
