A wave energy generating device floating and fixed on the coast

Abstract

The invention discloses a wave power generation device fixed by the coast in a floating manner. The wave power generation device comprises a floating structure and a hydraulic system, wherein the floating structure floats on the sea; the hydraulic system is connected with the floating structure and used for energy conversion; the floating structure comprises a floating body, a supporting frame and two connecting rods used for connecting the floating body with the supporting frame; the floating body adopts a hollow sealed structure which is formed by steel welding, and hinged with the supporting frame which can be fixed on the coast or a large-scale floating body, so that the floating body can swing around the supporting point along with waves; and one of the connecting rods is connected with the hydraulic system, so that mechanical energy generated from the swinging of the floating body can be converted into hydraulic energy, and the hydraulic energy can be transferred to the hydraulic system for power generation. The wave power generation device provided by the invention is high in wave energy absorption efficiency, highly adaptable to tidal level changes within a certain range, and lower in environmental pollution; and the possibility that the wave power generation device is damaged is reduced.

Description

technical field [0001] The present invention designs a wave energy generating device, and more particularly relates to a wave energy generating device floating and fixed on the coast. Background technique [0002] The wave energy generation devices used for wave energy development can be divided into shore wave energy generation devices, nearshore wave energy generation devices and offshore wave energy generation devices according to their deployment locations. In comparison, shore wave energy generation devices can be more easily connected to the grid and easier to maintain. However, the working condition of the wave energy generating device on the shore is easily affected by the tide level of seawater. Existing shore wave power generation devices cannot achieve optimal working conditions when the tide level is higher or lower than the design water level. [0003] On the other hand, many of the existing shore wave power generation devices do not consider the influence of ...

However, the working condition of the wave energy generation device on the shore is easily affected by the sea tide level

Existing shore wave power generation devices cannot achieve optimal working conditions when the tide level is higher or lower than the design water level

[0003] On the other hand, many of the existing shore wave power generation devices do not consider the influence of the shape of the floating body on the wave absorption efficiency, and often use the simplest shapes such as cylinders and cubes.

Even if the shore wave energy generation device with the shape of the wave-absorbing floating body is optimally designed, it does not have the function of changing the posture with the change of the tide level, and the advantages of the optimized wave-absorbing shape cannot be maximized
