Marine wave-energy power generating device

Abstract

The invention discloses a marine wave-energy power generating device. In the invention, a hydraulic cylinder serves as an input end of a hydraulic transmission system, a piston rod of the hydraulic cylinder is linked with a pendulum-bob water baffle through a gear transmission mechanism, and the body of the hydraulic cylinder is linked with a fixed base; an oil inlet / outlet port of an oil cavity of the hydraulic cylinder is forked into two paths, one path is linked with a high-pressure energy accumulator through an oil outlet one-way valve and a high-pressure pipeline, and the other path is linked with a medium-pressure energy accumulator through an oil-return one-way valve and an oil-return pipeline; a rodless cavity of the hydraulic cylinder is linked with a low-pressure air chamber through an air outlet and an air pipe of the rodless cavity; an extending side of a piston rod of the hydraulic cylinder is consolidated and tightly fit with a hydraulic cylinder cover to form a cylinderexternal cavity which is hermetically isolated from seawater, and the cylinder external cavity is linked with the low-pressure air chamber through an air outlet and an air pipe of the cylinder external cavity so as to assist the realization of the free reciprocating motion of the piston rod; and the high-pressure energy accumulator and the medium-pressure energy accumulator are respectively connected with a hydraulic motor, and the hydraulic motor drives a generator to work. According to the marine wave-energy power generating device disclosed by the invention, the purposes of energy saving, emission reduction, low carbon and environment friendliness can be achieved.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of marine renewable energy, and in particular relates to a marine wave energy generating device. Background technique [0002] With the development of the global economy, the increasing shortage of fossil raw materials and industrial pollution, the energy problem has gradually become a worldwide problem. Renewable energy and clean energy are widely valued all over the world, and the development and utilization of ocean energy has gradually become the focus of energy research and application in the future. The ocean, which accounts for 71% of the earth's surface area, contains huge renewable energy, mainly including ocean wind energy, tidal energy, wave energy, ocean current energy, temperature difference energy and salinity difference energy, etc. my country has a long coastline and abundant ocean energy resources. Therefore, vigorously developing and utilizing ocean energy has become a s...
