Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of offshore power generation, and in particular to an integrated system of a floating offshore photovoltaic and valve-type wave energy device. Background Art
[0002] The world is currently facing energy shortages and environmental pollution caused by fossil fuels. To solve these problems, people have developed new energy to a certain extent, especially the use of offshore energy, including wind energy, solar energy, wave energy, etc. Making full use of offshore energy is an important measure to get rid of fossil energy dependence and realize renewable energy supply. In order to make full use of solar energy resources, many photovoltaic power generation devices have been installed on land. However, photovoltaic panels on land often have too high a temperature due to direct sunlight, which seriously affects the power generation efficiency of photovoltaic panels. For floating offshore photovoltaics, the problem of too high temperature can be effectively solved by cooling with seawater. At the same time, in order to make more full use of offshore energy, a valve-type wave energy device is proposed, which can convert wave energy and effectively improve the utilization efficiency of offshore energy.
[0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Summary of the invention
[0004] The purpose of the present invention is to provide an integrated system of floating offshore photovoltaic and valve-type wave energy devices, which improves the utilization efficiency of offshore energy, reduces the impact of waves, and improves stability and safety.
[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] Floating offshore photovoltaic, including:
[0008] The support system includes several steel frames,
[0009] A photovoltaic power generation system, comprising a photovoltaic power generation panel supported by the support system;
[0010] A floating system, which includes a buoy floating on the water surface and arranged at the bottom of the support system to provide buoyancy;

[0013] The left valve body and the right valve body are connected to each other through a hinge axis and can rotate around the hinge axis.
[0014] A hydraulic cylinder is provided on the right valve body,
[0015] a piston rod, which is disposed on the left valve body and is slidably connected to the hydraulic cylinder,
[0016] A hydraulic control cabinet is connected to the hydraulic cylinder to convert hydraulic energy into electrical energy. When waves come, the left valve body and the right valve body are relatively displaced in the vertical direction, driving the piston rod and the hydraulic rod to perform piston movement. The hydraulic energy generated by the piston movement is converted into electrical energy through the hydraulic control cabinet.
[0017] In the integrated system of a floating offshore photovoltaic and valve-type wave energy device, the hydraulic control cabinet includes a hydraulic control device, a hydraulic motor and a generator, wherein the hydraulic motor is connected to the hydraulic cylinder to convert hydraulic energy into rotational energy, the generator is connected to the hydraulic motor to convert rotational energy into electrical energy, and the hydraulic control device is connected to the hydraulic motor for hydraulic adjustment.
[0018] In the integrated floating offshore photovoltaic and valve-type wave energy device system, the steel frame includes a bottom surface formed by horizontal support rods and an oblique support structure obliquely connected to the horizontal support rods.
[0019] In the integrated floating offshore photovoltaic and valve-type wave energy device system, the oblique support structure is a triangular sun-facing support.
[0020] In the integrated floating offshore photovoltaic and valve-type wave energy device system, three triangular sun-facing brackets are directly connected to every two buoys, and the three triangular sun-facing brackets fix two photovoltaic panels.

[0025] In the integrated system of floating offshore photovoltaic and valve-type wave energy device, the integrated system of floating offshore photovoltaic and valve-type wave energy device is a centrally symmetrical structure.
[0026] In the above technical scheme, the present invention provides a floating offshore photovoltaic and valve-type wave energy device integrated system, which has the following beneficial effects: the floating offshore photovoltaic and valve-type wave energy device integrated system realizes offshore floating photovoltaic power generation, and utilizes the energy generated by the waves on the sea. A circle of valve-type structures is surrounded by the floating offshore photovoltaic, and each valve-type structure is composed of two valve bodies. When the waves come, the two valve bodies will have relative displacement in the vertical direction. This relative displacement will cause the piston rod and piston cylinder above the valve body to have piston movement, and the piston movement will be converted into the rotation required by the generator through the hydraulic control cabinet, completing the conversion of wave energy. At the same time, the circle of valve-type structures around the floating offshore photovoltaic can also play a certain protective role for the floating offshore photovoltaic to a certain extent.
