[0002] In the solar photovoltaic power generation system, the photovoltaic support beam is an important component. Its main function is to serve as a supporting structure for fixing and supporting solar photovoltaic panels. These beams are usually made of metal materials such as aluminum alloy or stainless steel to ensure sufficient strength and weather resistance. The design and installation of photovoltaic support beams are crucial to the stability and efficiency of the entire photovoltaic system.

[0003] In the current solar power generation industry, the diversification of photovoltaic panel sizes is a common phenomenon. Although this diversity meets different occasions and needs, it also brings certain complexity to the installation work. Specifically, when installing photovoltaic panels, operators must carefully consider the specifications and sizes of each photovoltaic panel in order to select the photovoltaic bracket beams that match it. This process requires precise measurement and selection to ensure that the photovoltaic panels can be safely and stably installed on the bracket. This practice undoubtedly increases production costs;

[0004] In addition, keeping the photovoltaic support beams clean is also a key step in the installation process. Before and after assembling the photovoltaic panels, the supporting beams must be thoroughly cleaned to ensure that the performance of the photovoltaic panels is not affected.

[0005] Therefore, in order to solve the above problems, the present application provides a photovoltaic support beam.

The limiting parts 2 are connected by a transmission through an adjusting part 3. A driving part 4 for driving the adjusting part 3 to move is fixedly installed on the outer side of the groove at the top of the base 1, and a dust removal part 5 for removing dust from the limiting part 2 is fixedly installed at the end of the driving part 4. The adjusting part 3 includes a movable rod 301, a first rotating shaft 302, a second rotating shaft 303 and a moving block 304, wherein the movable rod 301 is staggered and cross-distributed by moving up and down through the first rotating shaft 302, and a moving block 304 is movably provided at the end of the movable rod 301 through the second rotating shaft 303.

[0021] The limiting portion 2 includes a bottom plate 201, a support block 202, a surrounding plate 203, a protruding rod 204 and a sliding groove 205, wherein the bottom plate 201 is movably arranged between the left and right grooves at the top of the base 1 through the support block 202, and the protruding rod 204 is fixedly installed at the top corner of the bottom plate 201, the surrounding plate 203 is enclosed on the outer side of the bottom plate 201, and the sliding groove 205 is fixedly installed on one side of the bottom plate 201 close to the adjustment portion 3.

[0022] The moving block 304 is movably engaged in the sliding groove 205 .

[0023] The driving part 4 includes a fixed tube 401, a piston rod 402, a spring 403, a mounting block 404 and a push plate 405, wherein the fixed tube 401 is fixedly mounted on the top of the base 1 through the mounting block 404, the piston rod 402 is arranged in the fixed tube 401 through the spring 403, and a push plate 405 is fixedly mounted on one end of the piston rod 402 close to the adjusting part 3.

[0024] The dust removal section 5 includes an air pump 501, a pressure relief valve 502 and an exhaust pipe 503, wherein the air pump 501 is fixedly installed at the end of the fixed pipe 401, and the air inlet end of the air pump 501 is connected to the interior of the fixed pipe 401, the pressure relief valve 502 is fixedly installed at the top of the fixed pipe 401, and the exhaust pipe 503 is connected to the interior of the fixed pipe 401 through the pressure relief valve 502.

[0025] The implementation principle of a photovoltaic support beam in the embodiment of the present application is:

[0026] When it is necessary to place a photovoltaic panel on the bottom plate 201, the air pump 501 is controlled to extract external air and continuously inject it into the fixed tube 401, so that a high-pressure airflow is formed in the inner cavity of the fixed tube 401. The high-pressure airflow pushes the piston rod 402 and the push plate 405 to move toward one side of the adjustment part 3 and compresses the spring 403 in the inner cavity of the fixed tube 401. Under the push of the push plates 405 on the left and right sides, the moving block 304 moves inward along the slide groove 205, so that the misaligned and cross-distributed movable rods 301 converge inward with the first rotating shaft 302 as the center, so that the front and rear bottom plates 201 move back to back until the loading area of ​​the bottom plate 201 is adapted to the photovoltaic panel to be placed, and the pressure supply to the inner cavity of the fixed tube 401 is stopped, so that the loading area of ​​the front and rear bottom plates 201 is constant;

[0027] After removing the photovoltaic panel from the protruding rod 204, the equipment needs to be reset and self-cleaned. At this time, the pressure relief valve 502 is controlled to release the pressure in the inner cavity of the fixed tube 401, and the high-pressure airflow cleans the surface of the bottom plate 201 through the exhaust pipe 503. At the same time, the piston rod 402 is gradually reset by the elastic traction of the spring 403. With the retraction of the piston rod 402 and the push plate 405, the first rotating shaft 302 is expanded again and the loading area of ​​the front and rear bottom plates 201 is reduced.
