Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic modules, and particularly relates to an adjusting bracket for a floating photovoltaic module on water surface. Background Technique

[0002] Solar energy is a renewable energy source that is inexhaustible for mankind, with advantages such as full cleanliness, absolute safety, relative extensiveness, definite long lifespan and maintenance-free, adequacy of resources, and potential economy; a photovoltaic module is a power generation device that converts solar energy into electrical energy, and using photovoltaic modules for power generation is one of the more widely used power generation methods currently. Since solar power generation requires the use of a large amount of space, vast water areas are excellent spaces that can be developed and utilized; compared with traditional photovoltaic power stations, floating photovoltaic on water installs photovoltaic power generation modules on the water surface, which has the advantages of not occupying land resources, and floating photovoltaic power stations can reduce water evaporation, improve water quality, and inhibit the growth of algae.

[0003] Currently, traditional floating photovoltaic modules on water surface directly fix and install the photovoltaic panel on the floating body, and the elevation angle is basically fixed during the initial installation; moreover, due to the large number of photovoltaic panels, a relatively large force is required to adjust the elevation angle when adjusting the elevation angle.

[0004] In view of the above-mentioned problems that the elevation angle of the floating photovoltaic module on water surface is inconvenient to adjust and a relatively large force is required when adjusting, the present invention designs an adjusting bracket for a floating photovoltaic module on water surface. Summary of the Invention

[0005] The purpose of the present invention is to provide an adjusting bracket for a floating photovoltaic module on water surface. Through the action of the floating component and the elevation angle adjusting bracket, by slowly releasing the air pressure inside the air cylinder part, the elevation angle of the photovoltaic panel is adjusted, so as to better maintain the orientation towards the sun and ensure the power generation efficiency of the photovoltaic panel; the problems of inconvenient elevation angle adjustment and relatively large force required when adjusting are solved.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0008] As a preferred technical solution of the present invention, the one-way exhaust valve adopts an electromagnetic one-way valve, the electromagnetic one-way valve is electrically connected with a microprocessor, the microprocessor controls whether the one-way exhaust valve is in the exhaust state, and the microprocessor adjusts the gas pressure stored inside the pressure bottle by stopping or exhausting through the one-way exhaust valve, and then adjusts the sliding position of the piston part inside the cylinder part.

[0009] As a preferred technical solution of the present invention, the two elevation angle control cylinders at one end of the fixed bracket are communicated with each other through an air pipe, and an inflation pipe A is fixedly installed on the pressure bottle of one of the elevation angle control cylinders.

[0010] As a preferred technical solution of the present invention, two elevation angle control cylinders are also assembled on both sides of the other end of the fixed bracket; the two elevation angle control cylinders at the other end of the fixed bracket are also communicated with each other through an air pipe, and an inflation pipe B is fixedly installed on the pressure bottle of one of the elevation angle control cylinders.

[0011] As a preferred technical solution of the present invention, the inflation pipe A and the inflation pipe B are respectively fixedly communicated with an air pump; the air pump supplements the gas pressure of the corresponding pressure bottle through the inflation pipe A and the inflation pipe B respectively.

[0012] As a preferred technical solution of the present invention, the sliding connection seat includes a limit sliding groove and a limit connection seat.

A limit sliding block is fixedly arranged at the bottom of the limit connection seat, and the limit sliding block is in sliding fit with the inner wall of the limit sliding groove. The function of the sliding connection seat is to provide the required movable displacement range for the hinge at the back of the photovoltaic panel when adjusting the elevation angle of the photovoltaic panel.

[0013] As a preferred technical solution of the present invention, the length of the internal sliding path of the limit sliding groove is higher than the length of the limit sliding block, and the difference range is 1 cm - 5 cm; the optimal difference range is 1 cm - 2 cm.

[0014] As a preferred technical solution of the present invention, a number of elevation control cylinders are evenly arranged in the middle of one end of the fixed support, and they are interconnected through an air pipe; a number of elevation control cylinders are evenly arranged in the middle of the other end of the fixed support, and they are also interconnected through an air pipe.

[0016] 1. Through the action of the floating component and the elevation adjustment bracket, the present invention provides sufficient buoyancy for the overall equipment such as the photovoltaic panel to achieve the floating function, and adjusts the elevation angle of the photovoltaic panel by slowly releasing the pressure of the air cylinder part, which has the advantage of better maintaining the orientation towards the sun and improving the power generation efficiency.

[0017] 2. Through the action of the elevation control cylinder and the one-way exhaust valve, during the day, the speed of releasing the pressure of the air cylinder part by using the on-off state of the one-way exhaust valve is used to adjust the elevation change of the photovoltaic panel to better face the sun; at the same time, compared with the traditional power telescopic and other methods, this method also does not need to resist the problem of large gravity and other acting forces caused by the large number of photovoltaic panels; it has the advantages of convenient elevation adjustment and stable adjustment speed.
