Abstract

A to-and-fro water pump type transformation tidal power generation device is provided, which comprises a foundation column, a water cylinder, a piston, a circular floating box, a high pressure water tank, a normal pressure water tank, a hydraulic generator, a connecting water pipe and working water. At high tide, the circular floating box rises along with the piston and the water cylinder sucks working water from the normal pressure water tank; at low tide, the circular floating box falls along with the piston and the working water is pressed into the high pressure water tank. Then, the working water in the high pressure water tank flows through the hydraulic generator and returns to the normal pressure water tank, and; the hydraulic generator generates electricity under the drive of water flow.

Description

Technical field [0001] The invention relates to a device for generating electricity using tidal power, and belongs to the technical field of power machinery. It is a reciprocating water pump type variable pressure tidal power generation device. Background technique [0002] At present, people attach importance to energy conservation and emission reduction, and yearn for renewable green energy. Tides in the ocean are a huge source of green energy. However, due to the low tidal head difference and serious metal corrosion in seawater, it is not suitable for the operation of hydroelectric generators, thus limiting the acquisition and application of tidal energy. The society is in urgent need of a new type of tidal power generation device that can not only convert the low-level difference water energy of the tide into a high-level water energy source, but also ensure that the hydroelectric generator is not corroded and operates safely, so as to obtain a large amount of tidal en...
