[0001] The invention relates to the technical field of control cabinets, in particular to a control cabinet for photovoltaic power generation. Background Art

[0002] Photovoltaic power generation, as a clean and renewable form of energy, has been widely used in recent years. Its main components include solar panels, controllers and inverters. Among these components, the control cabinet, as a key device, undertakes multiple functions such as protection, monitoring and control. In the photovoltaic power generation system, the photovoltaic effect of semiconductor materials is used to directly convert solar energy into electrical energy. With the rapid growth of global photovoltaic installed capacity, the application scenarios of control cabinets have extended from temperature-controlled plants to complex outdoor environments such as deserts, coastal areas, and high humidity. Long-term exposure to dust, rain, snow, salt spray and extreme temperature differences has faced severe challenges in its reliability. At the same time, the continuous innovation and development of photovoltaic control cabinet technology has also promoted the improvement of the overall performance of photovoltaic power generation systems. At the same time, with the continuous advancement of intelligent and automated technologies, photovoltaic control cabinets are also developing in a more intelligent and efficient direction to meet the needs of future energy transformation and sustainable development.

[0003] Patent announcement number CN117879479B is a working method of a solar control cabinet, which relates to a photovoltaic energy-saving electrical control cabinet; it includes a control cabinet body and a photovoltaic assembly slidably arranged on the surface of the control cabinet body; the photovoltaic assembly includes: a sliding frame, a deicing member and a driving member, the sliding frame includes a V-shaped mounting frame; two opposite sides of the V-shaped mounting frame are provided with sliding grooves; the deicing member includes a U-shaped seat slidably arranged between the two sliding grooves; an insulation pipe is fixed between the inner walls of the U-shaped seat; a mounting groove is provided on the side of the insulation pipe; and an elastic rubber sleeve adapted thereto is arranged in the mounting groove. The device controls the elastic rubber sleeve to be squeezed by water to expand toward the direction of the solar panel, gradually pressing against the surface of the solar panel, and the heated water in the insulation pipe heats and melts the ice layer on the surface of the solar panel to achieve deicing, replacing the traditional deicing method of scraping, effectively preventing the surface of the solar panel from being scratched, and improving the efficiency of deicing.

[0004] The above photovoltaic energy-saving electrical control cabinet device, when in use, although a de-icing mechanism is provided to remove ice on the surface of the photovoltaic panel, does not have a good effect in removing dirt blocked on the solar panel. In the face of sandstorm weather, a large amount of sand and dust will adhere to the surface of the photovoltaic panel, thereby affecting the power generation efficiency of the solar panel and making the device unable to work well in various extreme climates. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a control cabinet for photovoltaic power generation, which solves the problems raised in the above background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a control cabinet for photovoltaic power generation, including a main body, the upper end of the main body is fixedly connected to the lower end of the platform, the upper end of the platform is fixedly connected to the lower end of the photovoltaic panel, the inner wall of the main body is fixedly connected to the electronic component, the main body is provided with a heat dissipation hole, the main body is provided with a cleaning device for cleaning the light-receiving surface of the photovoltaic panel, the main body is provided with a compressed jet device to prevent the heat dissipation hole from blocking, and the main body is provided with a closed waterproof device to prevent water from seeping from the top of the main body;

[0007] Among them, the cleaning device includes a motor, a first gear, a second gear, a rotating shaft, a rotating rod, a short rod, a connecting rod, a cleaning rod, a cleaning scraper, a square groove, a reset spring, a fixed block, a large blocking block, a small blocking block and an L-shaped striking rod. The side end of the main body is fixedly connected to the motor, and the output end of the motor is fixedly connected to the first gear, and a fan is fixed to the output end of the motor. When the motor is started, the first gear is driven to rotate through the output end of the motor, and the fan can be driven to rotate to perform heat dissipation operations back and forth inside the main body.

[0008] According to the above technical solution, the first gear is meshed with the second gear, the second gear is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the inner wall of the main body. When the first gear rotates, it drives the second gear meshed with it to rotate, and when the second gear rotates, it drives the rotating shaft to rotate on the inner wall of the main body.

[0009] According to the above technical solution, the outer end of the rotating shaft is fixedly connected to the lower end of the rotating rod, the upper end of the rotating rod is fixedly connected to the lower end of the short rod, the upper end of the short rod is slidably connected to the inner wall of the connecting rod, the inner end of the connecting rod is fixedly connected to the outer end of the cleaning rod, the upper end of the cleaning rod is fixedly connected to the lower end of the pressure spring, and the upper end of the pressure spring is fixedly connected to the inner wall of the connecting rod. When the rotating shaft rotates, the rotating rod rotates with the rotating shaft as the center. At this time, the short rod slides on the inner wall of the connecting rod and drives the connecting rod to move laterally. When the connecting rod moves laterally, it drives the cleaning rod to move laterally synchronously. When the cleaning rod moves laterally, the cleaning scraper slides on the photovoltaic panel to clean the photovoltaic panel.

[0010] According to the above technical solution, a square groove is opened at the hinge between the cleaning rod and the connecting rod, the inner end of the square groove is fixedly connected to one end of the reset spring, the other end of the reset spring is fixedly connected to the large blocking block, the large blocking block is fixedly connected to the small blocking block, and the small blocking block is slidably connected to the inner wall of the square groove, the fixing block is fixedly connected to the platform, and the L-shaped striking rod is fixedly connected to the platform.

[0011] According to the above technical scheme, the compressed jet device includes a connecting pipe, a large pressurized cover, a large pressurized box, an air guide pipe, a pressurized nozzle, a rotating shaft, an air vent, a notched disk, a small rotating column, a connecting block, a sliding groove, a push-pull rod and a guide rod. The outer wall of the extrusion frame is fixedly connected to one end of the connecting pipe, and the other end of the connecting pipe is fixedly connected to the large pressurized cover, and the connecting pipe penetrates and slides to connect the inner wall of the main body. When the connecting rod moves laterally, it drives the extrusion cover to move laterally. When the extrusion cover moves laterally, it drives the extrusion frame to move laterally. When the extrusion frame moves laterally, the connecting pipe moves laterally synchronously, so that the connecting pipe slides in the main body. When the connecting pipe moves laterally, it pushes the large pressurized cover to move laterally on the inner wall of the large pressurized box, so that the gas in the large pressurized box guides the pressurized gas to between the heat dissipation holes through the air guide pipe, and the pressurized gas impacts the inner wall of the heat dissipation hole through the pressurized nozzle with a smaller opening, so that the pressurized gas cleans the heat dissipation hole.

[0012] According to the above technical scheme, the swivel is fixed on the top of the large pressurized box, and an air vent is provided at the upper end of the large pressurized box. The upper end of the swivel is rotatably connected to the notched disk, and the upper end of the notched disk is fixedly connected to the small rotating column. The upper end of the small rotating column is rotatably connected to the connecting block, and the connecting block is rotatably connected to the inner wall of the sliding groove, and the inner wall of the sliding groove is fitted with the push-pull rod, and the push-pull rod is rotatably connected to the guide rod. When the connecting pipe moves, it pushes the guide rod to move synchronously. When the guide rod moves, it pushes the push-pull rod to slide on the inner wall of the sliding groove. When the push-pull rod is pushed to slide to the end of the inner wall of the sliding groove, it squeezes the sliding groove, so that the connecting block rotates with the small rotating column as the center of the circle. When the connecting block rotates to the farthest point away from the guide rod, the small connecting block pushes the small rotating column to rotate the notched disk to expose the air vent, so that the compressed gas in the large pressurized box is intermittently reduced in pressure.

[0013] According to the above technical solution, the closed waterproof device includes a connecting roller, a tension spring, a U-shaped groove block, a tension column, a small pressurized cover, a small pressurized box and an airbag. The inner side of the connecting rod is fixedly connected to the connecting roller. When the connecting rod moves, it drives the connecting roller to move synchronously. The upper end of the main body is fixedly connected to the bottom end of the tension spring. The upper end of the tension spring is fixedly connected to the U-shaped groove block. When the connecting roller moves, the U-shaped groove block is squeezed so that the U-shaped groove block pulls the tension spring to lift. The bottom end of the U-shaped groove block is fixedly connected to the upper end of the tension column, and the tension column runs through the main body. When the U-shaped groove block is lifted, the tension column is pulled to slide upward.

[0014] According to the above technical solution, the lower end of the stretching column is fixedly connected to the upper end of the small pressurized cover, and the outer wall of the small pressurized cover is slidably connected to the inner wall of the small pressurized box. When the stretching column moves upward, the small pressurized cover moves synchronously and slides in the small pressurized box. The small pressurized box is fixedly connected to the airbag, and the small pressurized box and the cavity of the airbag are connected. When the small pressurized cover moves synchronously and slides in the small pressurized box, the gas in the small pressurized box is squeezed and flows to the airbag, causing the airbag to bulge.

[0015] The present invention provides a control cabinet for photovoltaic power generation. It has the following beneficial effects:

[0016] (1) The present invention sets a cleaning device. When the motor is started, the first gear is driven to rotate through the motor output end, so that the connecting rod moves laterally. When the connecting rod moves laterally, it drives the cleaning rod to move laterally synchronously. When the cleaning rod moves laterally, it drives the cleaning blade to move synchronously, so that the cleaning blade is in full contact with the photovoltaic panel, and the dirt accumulated on the photovoltaic panel in bad weather is removed, so as to prevent the power generation efficiency of the photovoltaic panel from being reduced due to the influence of the dirt. When the cleaning blade moves to the far end of the cabinet door, it is stuck and lifted by the large blocking block, and it will not be released until it moves to the close end of the cabinet door, so that the restriction is reset, so that the cleaning blade works and performs a one-way cleaning operation, so as not to bring the dirt back to the photovoltaic panel, resulting in unclean cleaning and affecting the working efficiency of the photovoltaic panel, and to prevent the dirt from being dragged to the opening of the main cabinet door and causing pollution to the cabinet door.

[0017] (2) The present invention sets a compressed jet device. When the connecting rod moves laterally, it drives the extrusion cover to move laterally. When the extrusion cover moves laterally, it drives the extrusion frame to move laterally. When the extrusion frame moves laterally, the connecting tube moves laterally synchronously, so that the connecting tube slides in the main body. When the connecting tube moves laterally, it pushes the large pressurized cover to move laterally on the inner wall of the large pressurized box, so that the gas in the large pressurized box is guided to between the heat dissipation holes through the air guide pipe, and the pressurized gas is impacted on the inner wall of the heat dissipation hole through the pressurized nozzle with a smaller opening, so that the pressurized gas cleans the heat dissipation hole, thereby preventing larger impurities from falling from the side wall of the photovoltaic panel when the photovoltaic panel is cleaned. When the guide rod moves, the push-pull rod is pushed to slide on the inner wall of the sliding groove. When the push-pull rod is pushed to slide to the end of the inner wall of the sliding groove, the sliding groove is squeezed to make the connecting block rotate with the small rotating column as the center. When the connecting block rotates to the farthest point away from the guide rod, the small connecting block pushes the small rotating column to rotate the notched disk to expose the vent, so that the compressed gas in the large pressurized box can reduce the pressure intermittently, so that the gas ejected from the pressurized nozzle will not continue to be like a wind wall, thereby blocking the gas exchange inside and outside the main body and preventing the cooling effect from being weakened.

[0018] (3) The present invention provides a closed waterproof device. When the connecting rod moves, it drives the connecting roller to move synchronously. When the connecting roller moves, it squeezes the U-shaped groove block, so that the U-shaped groove block pulls the stretching spring to lift. When the U-shaped groove block is lifted, it pulls the stretching column to slide upward. When the stretching column moves upward, the small pressurized cover moves synchronously and slides in the small pressurized box. At this time, the gas in the small pressurized box is squeezed and flows to the airbag, causing the airbag to swell and block the gap between the upper end of the main body and the cabinet door, preventing the water stirred up by the cleaning scraper from flowing along the gap to the inside of the main body and affecting the operation of the device.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 13 One embodiment of the present invention is: a control cabinet for photovoltaic power generation, including a main body 1, the upper end of the main body 1 is fixedly connected to the lower end of a platform 2, the upper end of the platform 2 is fixedly connected to the lower end of a photovoltaic panel 3, the inner wall of the main body 1 is fixedly connected to an electronic component 4, a heat dissipation hole 5 is provided on the main body 1, and a cleaning device 6 for cleaning the light-receiving surface of the photovoltaic panel 3 is provided on the outer wall of the main body 1.

[0035] Wherein, the cleaning device 6 includes a motor 601, a first gear 602, a second gear 603, a rotating shaft 604, a rotating rod 605, a short rod 606, a connecting rod 607, a cleaning rod 608, a cleaning blade 609, a square groove 610, a reset spring 611, a fixed block 612, a large blocking block 613, a small blocking block 614 and an L-shaped striking rod 615. The side wall of the main body 1 is fixedly connected to the motor 601, and the output end of the motor 601 is fixedly connected to the first gear 602. A fan is fixed to the output end of the motor 601. When the motor 601 is started, the fan can be driven to rotate to perform heat dissipation in the main body 1. The first gear 602 is driven to rotate by the output end of the motor 601, and the first gear 602 is meshed with the second gear 603. When the first gear 602 rotates, it drives the second gear 603 meshed therewith to rotate. The second gear 603 is fixedly connected to the rotating shaft 604, and the rotating shaft 604 is connected to the main body 1. The body 1 is rotatably connected. When the second gear 603 rotates, it drives the rotating shaft 604 to rotate. The outer end of the rotating shaft 604 is fixedly connected to the lower end of the rotating rod 605. The upper end of the rotating rod 605 is fixedly connected to the lower end of the short rod 606. The upper end of the short rod 606 is slidably connected to the inner wall of the connecting rod 607. When the rotating shaft 604 rotates, the rotating rod 605 rotates with the rotating shaft 604 as the center. At this time, the short rod 606 slides on the inner wall of the connecting rod 607 and drives the connecting rod 607 to move laterally. The inner end of the connecting rod 607 is fixedly connected to the outer end of the cleaning rod 608. When the connecting rod 607 moves laterally, it drives the cleaning rod 608 to move laterally synchronously. When the cleaning rod 608 moves laterally, it drives the cleaning blade 609 to move synchronously, so that the cleaning blade 609 is fully in contact with the photovoltaic panel 3, and the dirt accumulated on the photovoltaic panel 3 in bad weather is removed, so as to prevent the power generation efficiency of the photovoltaic panel 3 from being reduced due to the influence of dirt.

[0036] A square groove 610 is provided at the hinge of the cleaning rod 608 and the connecting rod 607, the inner end of the square groove 610 is fixedly connected to one end of a return spring 611, the other end of the return spring 611 is fixedly connected to a large blocking block 613, the large blocking block 613 is fixedly connected to a small blocking block 614, and the small blocking block 614 is slidably connected to the inner wall of the square groove 610, and a fixed block 612 is fixedly connected to the platform 2. When the cleaning rod 608 moves, the cleaning blade 609 hits the fixed block 612 to rotate and squeeze the large blocking block 613, so that the large blocking compresses the return spring 611, and the large return spring 611 retreats into the square groove 610. When the cleaning blade 609 rotates 90° to the upper end of the fixed block 612, the large blocking block 613 loses the squeezing of the cleaning blade 609 and pops out from the lower end of the cleaning blade 609, jamming the cleaning blade 609, so that the cleaning blade 609 9 is separated from the photovoltaic panel 3, so that when the cleaning blade 609 returns, the dirt is not dragged on the photovoltaic panel 3 to cause friction loss of the photovoltaic panel 3. An L-shaped striking rod 615 is fixedly connected to the platform 2. When the cleaning rod 608 drives the cleaning blade 609 to move horizontally back to the opening direction of the main body 1, the L-shaped striking rod 615 hits the small blocking block 614, causing the small blocking block 614 to slide to the depth of the square groove 610. When the small blocking block 614 slides to the depth, the large blocking block 613 fixedly connected to the small blocking block 614 moves synchronously to the depth of the square groove 610 and slides out from under the cleaning blade 609. At this time, the squeezing force of the large blocking block 613 is lost, and the cleaning blade 609 is reset to continue working, so that the dirt is not driven to move on the photovoltaic panel 3, which affects the working efficiency of the photovoltaic panel 3 due to unclean cleaning, and the dirt is prevented from being dragged to the opening of the main body 1 to affect the cleaning effect and working environment.

[0037] When the present embodiment is working, when the motor 601 is started, the output end of the motor 601 drives the first gear 602 to rotate, and when the first gear 602 rotates, the second gear 603 meshing therewith is driven to rotate, and when the second gear 603 rotates, the shaft 604 is driven to rotate, and when the shaft 604 rotates, the rotating rod 605 rotates with the shaft 604 as the center of the circle, and at this time, the short rod 606 slides on the inner wall of the connecting rod 607, and the short rod 606 squeezes the inner side of the connecting rod 607, so that The connecting rod 607 moves on the side wall of the main body 1. When the connecting rod 607 moves horizontally, it drives the cleaning rod 608 to move horizontally synchronously. When the cleaning rod 608 moves horizontally, it drives the cleaning scraper 609 to move synchronously, so that the cleaning scraper 609 fits the top surface of the photovoltaic panel 3 and moves back and forth to scrape off the impurities attached to the top of the photovoltaic panel 3. When the cleaning rod 608 moves horizontally away from the open end of the main body 1, the cleaning scraper 609 hits the fixed block 612 to rotate and squeeze the large blocking block 612. 13, the large blocking block compresses the return spring 611, and the large return spring 611 returns to the square groove 610. When the cleaning blade 609 rotates 90 degrees to the upper end of the fixed block 612, the large blocking block 613 loses the squeezing of the cleaning blade 609 and pops out from the lower end of the cleaning blade 609, blocking the cleaning blade 609. When the cleaning rod 608 drives the cleaning blade 609 to move horizontally back to the opening direction of the main body 1, the L-shaped striking rod 615 hits the small blocking block 614, causing the small blocking block 614 to move to the square groove. 610 slides deep, when the small blocking block 614 slides deep, the large blocking block 613 fixedly connected to the small blocking block 614 moves synchronously to the deep of the square groove 610 and slides out from under the cleaning blade 609. At this time, the squeezing force of the large blocking block 613 is lost, and the cleaning blade 609 is reset. The cleaning blade 609 is in a working state when it is far away from the opening and is lifted up when it is close to the opening to prevent dirt from being brought to the opening and affecting the working environment. The one-way dragging can avoid dragging the dirt back and forth on the photovoltaic panel 3.

[0038] See also Figure 1-Figure 13On the basis of the above embodiment, in another embodiment of the present invention, the side wall of the main body 1 is provided with a compression jet device 7 to prevent the heat dissipation hole 5 from being blocked, and the main body 1 is provided with a closed waterproof device 8 to prevent water seepage from the top of the main body 1.

When the connecting rod 607 moves laterally, it drives the connecting pipe 701 to move synchronously, so that the connecting pipe 701 slides in the main body 1, and the connecting pipe 70 The other end of the large pressurized cover 702 is fixedly connected, and the connecting pipe 701 penetrates and slidably connects to the inner wall of the main body 1, and the outer wall of the large pressurized cover 702 is slidably connected to the inner wall of the large pressurized box 703. When the connecting pipe 701 moves laterally, the large pressurized cover 702 is pushed to move laterally on the inner wall of the large pressurized box 703. The outer end of the large pressurized box 703 is fixedly connected to the air guide pipe 704, and the outer end of the air guide pipe 704 is fixedly connected to the pressurized nozzle 705. The internal cavity of the large pressurized box 703 and the air guide pipe 704 and the pressurized nozzle 705 is connected, so that the gas in the large pressurized box 703 is guided to the heat dissipation holes 5 through the air guide pipe 704, and the pressurized gas is passed through the opening The smaller pressurized nozzle 705 impacts the inner wall of the heat dissipation hole 5, so that the pressurized gas cleans the heat dissipation hole 5, and prevents larger impurities from falling from the side wall of the photovoltaic panel 3 to the heat dissipation hole 5 when the photovoltaic panel 3 is cleaned, blocking the heat dissipation hole 5 and affecting the heat dissipation effect; the swivel 706 is fixed on the top of the large pressurized box 703, and the upper end of the large pressurized box 703 is provided with a venting port 707. The upper end of the swivel 706 is rotatably connected to the notched disk 708, and the upper end of the notched disk 708 is fixedly connected to a small rotating column 709. When the notched disk 708 rotates, the small rotating column 709 is driven to move synchronously. The upper end of the small rotating column 709 is rotatably connected to the connecting block 710. When the small connecting block 710 moves, it drives the small rotating column 709 to move synchronously. The small rotating column 709 is moved, and the connecting block 710 is rotatably connected with the inner wall of the sliding groove 711. When the sliding groove 711 moves, the connecting block 710 rotates around the small rotating column 709, and the inner wall of the sliding groove 711 fits with the push-pull rod 712. When the push-pull rod 712 is pushed to the bottom, the sliding groove 711 is squeezed and moves synchronously, and the push-pull rod 712 is rotatably connected with the guide rod 713, so that the notched disk 708 rotates to expose the air vent 707, so that the compressed gas in the large pressurized box 703 is intermittently reduced in pressure, so that the gas ejected from the pressurized nozzle 705 will not continuously eject the wind wall formed, thereby blocking the gas exchange inside and outside the main body 1 and preventing the cooling effect from being weakened.

[0039] In addition, the closed waterproof device 8 includes a connecting roller 801, a tension spring 802, a U-shaped groove block 803, a tension column 804, a small pressurized cover 805, a small pressurized box 806 and an air bag 807. When the connecting rod 607 moves, the connecting roller 801 is driven to move synchronously, the upper end of the main body 1 is fixedly connected to the bottom end of the tension spring 802, and the upper end of the tension spring 802 is fixedly connected to the U-shaped groove block 803. When the connecting roller 801 moves, the U-shaped groove block 803 is squeezed, so that the U-shaped groove block 803 pulls the tension spring 802 to rise, the bottom end of the U-shaped groove block 803 is fixedly connected to the upper end of the tension column 804, and the tension column 804 runs through the main body 1.

When the stretching column 804 moves upward, the small pressurized cover 805 moves synchronously and slides in the small pressurized box 806. The small pressurized box 806 is fixedly connected to the airbag 807, and the cavities of the small pressurized box 806 and the airbag 807 are connected. When the small pressurized cover 805 moves synchronously and slides in the small pressurized box 806, the gas in the small pressurized box 806 is squeezed and flows to the airbag 807, causing the airbag 807 to swell, thereby blocking the gap at the connection between the upper end of the main body 1 and the cabinet door, preventing the water stirred up by the cleaning scraper 609 that moves at this time from flowing along the gap to the inside of the main body 1 and affecting the operation of the device.

[0040] When the present embodiment is working, when the connecting rod 607 moves laterally, the connecting tube 701 slides in the main body 1. When the connecting tube 701 moves laterally, the large pressurized cover 702 is pushed to move laterally on the inner wall of the large pressurized box 703, so that the gas in the large pressurized box 703 is guided to the heat dissipation holes 5 through the air guide pipe 704, and the pressurized gas is impacted on the inner wall of the heat dissipation holes 5 through the smaller opening pressurized nozzle 705, so that the pressurized gas cleans the heat dissipation holes 5. When the connecting tube 701 moves, it pushes The guide rod 713 moves synchronously. When the guide rod 713 moves, it pushes the push-pull rod 712 to slide on the inner wall of the sliding groove 711. When the push-pull rod 712 is pushed to slide to the end of the inner wall of the sliding groove, it squeezes the sliding groove, causing the connecting block 710 to rotate with the small rotating column 709 as the center. When the connecting block 710 rotates to the farthest point away from the guide rod 713, the small connecting block 710 pushes the small rotating column 709 to rotate the notched disk 708, exposing the air vent 707, thereby reducing the pressure of the compressed gas in the large pressurized box 703.

[0041] When the connecting rod 607 moves, it drives the connecting roller 801 to move synchronously. When the connecting roller 801 moves, it squeezes the inner inclined surface of the U-shaped groove block 803, so that the U-shaped groove block 803 moves upward due to the squeezing force, and pulls the stretching spring 802 to stretch and deform. When the U-shaped groove block 803 is lifted, the stretching column 804 is pulled to slide upward. When the stretching column 804 moves upward, the small pressurized cover 805 moves synchronously and slides in the small pressurized box 806. At this time, the gas in the small pressurized box 806 is squeezed and flows to the airbag 807, causing the airbag 807 to swell, blocking the gap at the connection between the upper end of the main body 1 and the cabinet door.
