A tidal level adaptive floating pendulum wave power generation system

Abstract

The invention discloses a floating swing type wave power generation system self-adaptive to the tide level. The floating swing type wave power generation system comprises a floating body structure floating on the sea surface and a hydraulic system connected with the floating body structure and used for energy conversion. The floating body structure comprises a floating body, a support, a pair of synchronous belt wheels synchronously connected through a synchronous belt, and a connection rod connected between the two synchronous belt wheels. The floating body is of a sealed structure formed by welding hollow steel. The floating body is hinged to the support fixed to the coast or a large floating body so that the floating body can swing around a fulcrum along with fluctuation of waves. The connection rod is connected with the hydraulic system, converts the mechanical energy of swinging of the floating body into hydraulic energy, and transmits the hydraulic energy to the hydraulic system for power generation. By means of the floating swing type wave power generation system, the high wave energy absorption efficiency can be achieved, the adaptive capacity for the tide level changes within a certain range is high, pollution to the environment is reduced, and the probability that the floating swing type wave power generation system itself is damaged is lowered.

Description

technical field [0001] The invention designs a wave energy generating device, and more specifically relates to a floating pendulum type wave energy generating system with self-adaptive tide level. 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 ...

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
