Problems solved by technology

This solution requires a special induction coil, which can only be applied to the power supply of marine hydrometeorological data telemetry buoys or similar devices, which is not practical and has a narrow application range
[0008] 5. The mechanical type of double ratchet, the wave energy absorbing device is too complicated, which affects the efficiency of its absorption. In addition, the movement and power in the transmission process will be reversed, which will cause a large energy loss during the transmission process and low conversion efficiency of wave energy. Therefore, there is no widely used

Abstract

The mechanical switching equipment for wave energy generator includes one floating ball, one first shaft connected to the floating ball and provided with one first unidirectional clutch and one second unidirectional clutch of opposite rotation directions, one second shaft with one chain wheel and one reversing gear, and one power output shaft with one third unidirectional clutch and one gear type unidirectional clutch. The first unidirectional clutch and the third unidirectional clutch are connected through one chain, the second unidirectional clutch is connected to one chain wheel through the chain, and three shafts are fixed by means of bearings and supported in shore side. When the floating ball is driven by waves to move up and down, the first shaft is rotated, the power output shaft rotates always in one direction owing to the reversing of the clutches and gear, the clutches on the power output shaft prevent the feedback of the power, and the power is output to the generator via one coupling.

Description

technical field [0001] The invention relates to the technology of utilizing ocean wave energy to generate electricity, in particular to a mechanical wave energy generation conversion device. Background technique [0002] Starting from the oil crisis in the 1970s, countries began to shift their attention to using local resources and finding the most suitable cheap energy. The 21st century is the century of the ocean. It is an inevitable trend for human beings to seek resources from the sea. Coastal areas place their hopes on the surging waves. Therefore, using wave energy to generate electricity has profound significance for solving energy crisis and environmental problems. [0003] At present, there are mainly the following methods for absorbing energy from ocean waves at home and abroad: [0004] 1. Use the vertical fluctuation of the waves to push the water turbine or the air turbine with the air as the medium to generate electricity. The energy conversion process is wa...
