System and method for generating power by ocean water electricity clean new energy through gravity drop

Abstract

The invention provides a system for generating power by ocean water electricity clean new energy through gravity drop, and further provides a floating body and a power generation method using the power generation system to generate electricity. The system comprises a seawater filtering subsystem, a water inlet subsystem, a cavity acceleration subsystem and a hydroelectric power generation subsystem. The seawater filtering subsystem comprises at least one filtering device. The water inlet subsystem comprises a flow control device and a flow rate control device. The cavity acceleration subsystemis of a telescopic cylinder shape. In the transportation state, the cavity acceleration subsystem contracts; and in a power generation state, the cavity acceleration subsystem is unfolded and is vertically arranged in seawater. The hydroelectric power generation subsystem comprises a hydraulic turbine, and the hydraulic turbine is arranged at the bottom of the cavity acceleration subsystem. A seawater power generation system is stable in energy source, long in power generation time, high in energy conversion efficiency, wide in application range and capable of moving, can realize global all-weather general adaptation, and overcomes the defects of other marine new energy technologies.

Description

[0003] No matter whether the above-mentioned different clean new energy technologies are mature or not, no matter what stage of research and development they are in, they all have five things in common: A. Unstable energy sources; B. Short power generation time; C. Low energy conversion efficiency; D. Scope of application limited; E, immovable

[0004] Marine wind energy, tidal energy, wave energy, and tidal current energy are all technologies that depend on the sky for power generation. The wind direction, wind speed, flow speed, and sunlight intensity are complex and changeable, and are extremely unstable, resulting in short power generation time and long idle time, making it impossible to achieve 7 Continuous power generation 24 hours a day, unable to achieve stable output, difficult to grid-connected power generation, low energy conversion efficiency, coupled with unstable energy sources, so that the above technologies can only achieve hundreds of kilowatts or megawatts on a global scale, which is different from traditional The single-unit power of onshore hydropower varies greatly from one million kilowatts, only one-thousandth to one-hundredth of the single-unit power, which is difficult to commercialize and industrialize
