wave power generator

Abstract

The invention discloses a wave power generator, which comprises a power generation device, a driving device for driving the power generation device to generate power, and a fluctuation device for controlling the driving device to act. The wave power generator is characterized in that the fluctuation device comprises a counterweight base, at least one sliding way and a wave acquisition plate, wherein the sliding way is parallel to the counterweight base; the wave acquisition plate is coaxially and movably connected to each sliding way, and can reciprocally slide along a direction parallel to the sliding way; at least two elastic inhaul cables are connected to the wave acquisition plate; the two ends of the elastic inhaul cables are fixedly connected with the two ends of the sliding way respectively; the driving device comprises a hydraulic motor, a hydraulic cylinder and a piston rod; the hydraulic cylinder is connected with the hydraulic motor through a hydraulic pipeline; one end of the piston rod is connected with the fluctuation device, and the other end of the piston rod is inserted into the hydraulic cylinder, and can be reciprocally twitched along the direction parallel to the sliding way under the driving of the fluctuation device. The wave power generator is convenient to maintain; the wave power generator is provided with a resetting device, so that the wave power generator can be prevented from being damaged by great waves, and the influence of small waves on the power generation efficiency can be prevented.

Description

technical field [0001] The invention relates to a power generation device, in particular to a wave power generator. Background technique [0002] Three-quarters of the earth's surface is ocean, which has a vast area and has the characteristics of "three feet of waves without wind". The energy contained in seawater is not only endless, but also clean and environmentally friendly. Modern ocean energy development mainly refers to the use of ocean energy to generate electricity. There are many ways to use ocean energy to generate electricity, including wave power generation, tidal power generation, tidal current power generation, seawater temperature difference power generation, and seawater salt concentration difference power generation. [0003] At present, the main form of ocean energy power generation that has been developed and utilized at home and abroad is tidal power generation, which is to build a water retaining dam in the bay to form a reservoir, and use the rise and...

Problems solved by technology

In recent years, there is a marine power generation device that uses the thrust of ocean waves to convert ocean wave energy into high-speed flowing gas, and then the gas drives the blades of the air turbine to rotate to generate electricity. The interaction time between gas and blades is short, the energy absorption is small, and the energy conversion rate low, and its equipment structure is complex and maintenance costs are high

There is also a power generation device that uses the float to fluctuate with the waves to drive power generation. The movement of the float with this structure is easily controlled by the size of the wave. When the wave is too large or too small, it is easy to affect the power generation efficiency
