Hydraulic wave energy generator

Abstract

A hydraulic wave energy generating device includes an absorbing device, a converting device and a generating device. The absorption device is composed of a float and a connecting rod, and the float is immersed in seawater. The conversion device and the power generation device are arranged in the buoy body. The conversion device is composed of a hydraulic cylinder, a supercharger, a reversing valve, a speed regulating valve, an accumulator, and a hydraulic motor. The float moves up and down under the action of waves, and the hydraulic cylinder piston moves up and down through the connecting rod. The hydraulic oil drives the hydraulic motor to rotate through the supercharger, reversing valve, and speed control valve. The accumulator plays the role of energy storage and voltage stabilization. The power generation device is composed of a generator, and the hydraulic motor is connected with the generator with a coupling to drive the generator to generate electricity. The invention mainly uses the hydraulic system to transfer energy, and realizes the conversion from ocean wave energy to buoy mechanical energy, then to hydraulic energy, then to motor mechanical energy, and finally to electric energy. The hydraulic wave energy generating device has a simple structure and is easy to install, and can be well applied to small ocean buoys.

Description

technical field [0001] The invention relates to the technical field of marine energy utilization, in particular to a marine wave energy power generation device. The device is a hydraulic transmission device, which uses the movement of ocean wave energy to drive hydraulic transmission and generate electricity. Background technique [0002] Ocean wave energy is a renewable energy with wide distribution and high energy flow density in the ocean. Using wave energy to supply power to marine equipment and island residents is of great significance in ocean exploration, fishery development, and marine military affairs. The hydraulic wave energy generation method is a kind of offshore wave energy development method. Since the hydraulic system has the same power, the hydraulic actuators are small in size, light in weight, and compact in structure, and various components of the hydraulic transmission can be arranged conveniently and flexibly according to needs, so it is important to us...
