Automatic water pumping device using tidal energy

Abstract

The invention discloses an automatic water pumping device using tidal energy, comprising a fixed water tank, a floating body assembly capable of moving up and down and a water pipe, wherein the floating body assembly is located on the upper part of the fixed water tank, and comprises a floating water tank, a top cover and a hollow floating box; the top cover is connected with the upper end of the floating water tank into a whole; the floating box is fixedly connected to the periphery of the top cover; sea water capable of increasing the weight of the floating box is added in the cavity of the floating box during falling tide; a flexible water inner container is arranged in a cavity formed by the fixed water tank and the floating water tank; one end of the water pipe is fixedly connected with the lower part of the fixed water tank and extends into the water inner container; the other end of the water pipe extends out of the sea level. According to the automatic water pumping device using tidal energy with such a structure, the sea water can be conveyed to a position higher than the sea level without external power, various disadvantages of using the tidal energy for power generation in the prior art can be overcome, the existing power generation mode with low water head and high flow is changed, the power generation operation cost is reduced, and the device is environment-friendly and clean.

Description

technical field [0001] The invention relates to an automatic water pumping device of tidal energy. 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 c...

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.

At present, there is no such automatic pumping device for ocean tidal energy, which can transport seawater to a storage tank above sea level without external power
