[0001] The present invention relates to the technical field of photovoltaic microgrids, and in particular to a switch cabinet for photovoltaic microgrids with a heat dissipation function. Background Art

[0002] The photovoltaic microgrid switchgear with heat dissipation function integrates the electrical protection and heat dissipation management of the photovoltaic system. It is an important component of the photovoltaic microgrid system, which can effectively protect electrical equipment and optimize system performance.

[0003] The patent announcement number CN207603027U involves a switch cabinet for photovoltaic microgrids with heat dissipation function, including a cabinet body and a base. The top of the cabinet body is fixedly connected to a top plate. The top of the cabinet body is connected to a through pipe. The top of the through pipe passes through and extends to the top of the top plate. The top of the through pipe is fixedly connected to an exhaust device located at the top of the top plate. The exhaust device includes a fixed plate. The outer side of the fixed plate is fixedly connected to a blade. The bottom of the blade is fixedly connected to a bearing. Through the setting of the exhaust device, the patent uses the natural wind speed in nature to drive the turbine to rotate, and uses centrifugal force and negative pressure effect to make the air inside and outside the cabinet convect, which can quickly discharge the heat inside the cabinet and achieve the effect of heat dissipation. In addition, the exhaust device does not require electricity, is noiseless, can operate for a long time, and achieves the effect of energy saving and environmental protection.

[0004] In the above patent, by setting up an exhaust device, the natural wind speed in nature is used to drive the turbine to rotate, and the centrifugal force and negative pressure effect are used to make the air convection inside and outside the cabinet, which can quickly discharge the hot air inside the cabinet and achieve the heat dissipation effect. In addition, the exhaust device does not require electricity, is noiseless, and can operate for a long time, achieving the effect of energy saving and environmental protection. However, the heat dissipation of the photovoltaic microgrid switch cabinet in the above patent is unstable. At the same time, during long-term use, the surface of the heat dissipation device is prone to accumulate too much dust or foreign matter, resulting in further reduction of the heat dissipation effect. For this reason, a photovoltaic microgrid switch cabinet with a heat dissipation function and better heat dissipation effect is designed. Summary of the Invention

[0007] According to the above technical solution, the moving block is fixedly connected to the U-shaped plate, and the vibration plate is fixedly connected to the end of the U-shaped plate away from the fan. The movement of the moving block drives the movement of the U-shaped plate, and the movement of the U-shaped plate drives the movement of the exhaust port, thereby realizing the exhaust function, and the movement of the U-shaped plate drives the movement of the vibration plate.

[0008] The U-shaped plate is moved upward to drive the movable plate to move, the movable plate moves to drive the U-shaped plate to move, and the U-shaped plate moves to drive the filter plate to move.

[0009] According to the above technical solution, the water tank is provided with a second fixed groove, and a telescopic elastic rod is fixedly connected inside the second fixed groove. The free end of the telescopic elastic rod is fixedly connected to the receiving plate. The movement of the fixed block drives the convex plate to move. The movement of the convex plate contacts and squeezes the convex block to move to the side away from the convex plate. The movement of the convex block drives the receiving plate to move. The movement of the receiving plate drives the telescopic end of the telescopic elastic rod to extend and retract. Then the telescopic elastic rod is reset to drive the convex block to squeeze the convex plate.

[0010] According to the above technical solution, the side of the convex plate close to the limiting groove is set as an arc surface, and the side of the protrusion close to the convex plate is set as an arc surface. The convex plate moves to contact and squeeze the protrusion to move away from the convex plate.

[0014] The present invention provides a switch cabinet for photovoltaic microgrids with heat dissipation function. It has the following beneficial effects: (1) The photovoltaic microgrid switch cabinet with heat dissipation function operates through the cooperation of the frame, fixed frame, fan, screw, moving block, U-shaped plate, vibration plate and filter plate. The vibration plate moves and collides with the filter plate to generate vibration. The surface of the filter plate is vibrated to clean some dust and dirt, thereby protecting the equipment. If it is not cleaned for a long time, dust and dirt will accumulate, which may cause damage to the equipment and reduce the service life of the equipment. When closed, the interior of the equipment is protected to prevent dust from entering the interior to damage items and increase subsequent maintenance costs.

[0015] (2) The photovoltaic microgrid switch cabinet with heat dissipation function realizes the movement of the filter plate 2 and filters the water in the water tank through the coordinated operation among the water tank, the movable plate, the U-shaped rod, the filter plate 2, the fixed block, the convex plate, the convex block, the receiving plate, and the telescopic elastic rod, thereby preventing the water from containing impurities during subsequent cleaning. The fixed block is intermittently opened, which reduces the use of drainage volume, allowing the water to flow out in multiple times to improve the heat dissipation effect. The water flow from the inside of the water tank is intermittently discharged to cool the outer wall of the equipment, preventing the outer wall temperature of the equipment from being too high, causing damage to the equipment and reducing the service life of the equipment.

[0016] (3) The photovoltaic microgrid switch cabinet with heat dissipation function can clean the surface of the filter plate 2 through the coordinated operation of the moving rod, scraper, rotating rod and baffle, so as to prevent excessive impurities on the surface of the filter plate 2, which will affect the filtering effect of the filter plate 2 and prevent equipment damage. When too much impurities accumulate, the baffle will be squeezed, causing the baffle to open and the impurities and garbage to be discharged. Regular cleaning of impurities can prevent excessive accumulation of impurities and dirt on the filter plate 2, which will reduce the filtering effect of the filter plate 2 and cause equipment damage, thereby reducing the service life of the equipment.

The moving rod 19 moves upward and moves along with the inside of the chute 3 105. At the same time, the scraper 20 moves to scrape the surface of the filter plate 2 13, thereby cleaning the surface of the filter plate 2 13 and preventing excessive impurities on the surface of the filter plate 2 13 from affecting the filtering effect of the filter plate 2 13, preventing equipment damage and increasing subsequent maintenance costs.
