Wave energy power generating device

Abstract

The invention relates to a wave energy power generating device and belongs to the field of power generating devices. The wave energy power generating device comprises a water-turbine generator set and one or more wave energy water pumping assemblies; each wave energy water pumping assembly comprises a high pressure air buffering water storing chamber and a plurality of water pumps, wherein the water pumps are used for injecting seawater into the high pressure air buffering water storing chamber in one direction after the seawater is pressurized; the high pressure air buffering water storing chamber comprises a water storing chamber body, and the water storing chamber body is installed in the sea, a cavity is formed in the water storing chamber body, the cavity communicates with the water-turbine generator set through a pipeline; and all the water pumps communicate with the cavity through the pipelines provided with one-way valves. According to the wave energy power generating device, unstable wave energy can be transformed into electric energy, by adoption of the mode that water is pumped dispersedly and then centralized to push the water-turbine generator set for power generation, the wave energy water pumping assemblies become main investment parts of the power generating device, the wave energy water pumping assemblies do not include electric appliance equipment, and manufacturing cost is low, so that the ratio of output to input of the power generating device is high, and the wave energy power generating device is economically practical.

Description

technical field [0001] The invention relates to a power generation device, in particular to a wave energy power generation device which uses wave energy to extract seawater and then use it to generate electricity. Background technique [0002] The vast sea contains abundant energy, such as tidal energy, ocean current energy, wave energy, temperature difference energy, salinity difference energy, etc. In today's world where conventional energy is increasingly scarce and the contradiction between environmental protection and economic development is becoming increasingly acute, renewable energy The utilization of energy increasingly reflects its value. Among the above-mentioned various ocean energies, wave energy has been valued by people because of its extensive existence. In the past hundred years, inventors around the world have conducted extensive research and exploration on wave power generation, and some achievements have been commercially applied in special environments ...

Problems solved by technology

However, due to the large investment-output ratio, harsh marine environment, and high equipment maintenance costs, many ideas and even various patents are still in the stage of laboratory or exploratory trial operation. They are really economically feasible and can be used in ordinary marine environments. The solution to achieve large-scale application has not yet appeared
