Sea tidal fall water pumping device

Abstract

The invention discloses a sea tidal fall water pumping device comprising a fixing water cylinder, a float assembly capable of vertically moving and a water pipe; the float assembly is positioned above the fixing water cylinder, and is provided with a hollow floatation box; during ebb tide, the hollow cavity of the floatation box has sea water for increasing the weight of the floatation box; during ebb tide, the lower part of the float assembly is sealed with the upper part of the fixing water cylinder; one end of the water pipe is communicated with the lower part of the fixing water cylinder; and the other end of the water pipe extends out of sea level. The sea tidal fall water pumping device adopting such a structure can convey sea water to the position higher than the sea level without adopting external power, can overcome the multiple defects of the tidal power generation in the prior art, can change the low-water head large-flow power generation mode in the prior art, and can improve the environment of construction and foundation processing of the existing power generation station and the slit-prevention engineering project, thus reducing power generation investment, reducing power generation operation cost and achieving cleanliness and environment friendliness.

Description

technical field [0001] The invention relates to an ocean tide drop pumping 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 electricity at high tide and run at ebb tide, but cannot generate e...

Problems solved by technology

There are also limitations due to the inability to generate electricity continuously

As a clean energy source, tidal power generation has been researched on how to use it. The current tidal power generation has a large flow rate and low water head. The reason is that high water head cannot be achieved without power.

There is no such ocean tidal drop pumping device that can transport seawater to a storage tank above sea level without external power
