[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] 1. In this invention, the mounting frames of two adjacent photovoltaic modules are connected by inserts and slots, and the positions of the connecting frame and inserts are fixed by locking bolts. At the same time, the bidirectional screws in the same row of photovoltaic modules are connected by inserts and holes to realize the connection of the bidirectional screws in the row. As the bidirectional screws rotate, the screw blocks and the bidirectional screws are threaded together, and the sweeping plate is driven to slide along the slide bar through the connecting rod to clean the surface of the photovoltaic panel. The dirt accumulated on the photovoltaic panel is discharged from the sewage trough of the mounting frame. Distributed control maintains the efficient power generation of the photovoltaic modules.

[0018] 2. The protruding strip at the extended end of the electric push rod of the present invention can pass through the interior of the first gear and the second gear through telescopic extension. Through the engagement of the slot and the protruding strip, the first motor can drive the first gear to rotate and mesh with the first gear ring. The first insert plate drives the switch to move, realizing the opening and closing of the mains power transmission device. At this time, the protruding strip is only engaged with the slot of the first gear. When the protruding strip is engaged with the slot of the second gear, the first motor can drive the second gear to rotate and mesh with the second gear ring, so that the second insert plate inside the collar drives the switch on one side of the energy storage device to open or close. When the mains power transmission device is on, the switch of the energy storage device can be opened at the same time to realize the coordinated replenishment of electrical energy. The protruding strip can also be engaged in the slots of the first gear and the second gear at the same time, so that the first gear and the second gear can be rotated at the same time, thereby switching the two sets of switches, one open and one closed.

[0019] 3. In this invention, the bidirectional screws of three rows of photovoltaic modules are connected by a first transmission belt, and the connecting shaft passes into the control box and is connected to the third gear by a second transmission belt. When the second gear ring rotates and meshes with the third gear, it drives the bidirectional screws to rotate, thereby cleaning the photovoltaic panels by the sweeping plate on the top of the mounting frame.

[0020] 4. This invention uses a cooling fan inside the heat dissipation box to cool the inside of the control box. Each time the output end of the first motor is connected to the second gear through the switching component, that is, when the monitoring and identification lens detects that the voltage and current values ​​on the display screen of the mains power transmission device are insufficient, the extension end of the electric push rod retracts, driving the horizontal plate and the insertion rod to move outward of the control box. At the same time, the vertical frame and the toothed plate move, and the toothed plate moves along the limit frame to engage with the fourth gear, so that the monitoring and identification lens rotates to the display screen position of the energy storage device to monitor the output of the energy storage battery and monitor the remaining power value. At the same time, as the vertical frame moves, the pull rod pulls the horizontal frame to move, so that the scraper moves along the outer wall of the control box to clean the filter screen and prevent the vents from being blocked, thus affecting heat dissipation.

A transmission assembly 5 is provided at the bottom of the monitoring and identification lens 17. A display screen 15 is fixed on the side of the energy storage device 11 and the mains power transmission device 12 facing the monitoring and identification lens 17. The switching assembly 4 includes a rotating disk 41, which is rotatably installed on the inner wall of the control box 1. A collar 42 is rotatably fitted onto the surface of the rotating disk 41. Both the rotating disk 41 and the collar 42 have internal grooves 413. A first insert plate 415 is slidably inserted into the groove 413 of the rotating disk 41, and a second insert plate 418 is slidably inserted into the groove 413 of the collar 42. The first insert plate 415 and the second insert plate 418 correspond to two blades 112 respectively, and are staggered. A shaft 113 is rotatably mounted on the first insert plate 415 and the second insert plate 418 at the positions corresponding to the blades 112, and the shaft 113 is fixedly connected to the handle of the blades 112. A first spring 414 is fixedly installed inside the groove 413, and the first spring 414 is fixedly connected to the insert plate. The transmission assembly... The fourth gear 51 is rotatably mounted on the top of the control box 1 at the bottom of the monitoring and identification lens 17. A toothed plate 52 is meshed with one side of the fourth gear 51. When using the device, the photovoltaic modules 2 are spliced ​​and installed in a distributed arrangement. The control device 18 in the control box 1 is connected to the energy storage device 11 and the mains power transmission device 12, and is also connected to the electrical equipment connection terminal. The output voltage and current of the mains power transmission device 12 are monitored through the monitoring and identification lens 17. When needed, the energy storage device 11 is switched to supply power simultaneously through the switching component 4. The control device 18 in this solution can be used for power supply in AC transmission above 750 kV, large-scale power grid security and defense systems, and intelligent dispatching systems.

[0042] Distributed generation: such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the photovoltaic module 2 further includes: a post 23, a movable slot 24, a connecting frame 25, and a slot 211. The mounting frame 21 is a triangular bracket, and the posts 23 are slidably inserted into the three corners on one side of the mounting frame 21. A slot 211 is provided on the other side of the mounting frame 21. The movable slots 24 are provided on the mounting frame 21 corresponding to the positions of the three posts 23. The connecting frame 25 is slidably installed in the three movable slots 24. A drainage trough is provided on the bottom of the mounting frame 21 corresponding to the bottom of the photovoltaic panel 22. A locking bolt 26 is threaded into the bottom of the mounting frame 21 at one end corresponding to the post 23. 6. The mounting bracket 21 is locked to the connecting frame 25. A bidirectional screw 27 is rotatably mounted on the top of the photovoltaic panel 22. A screw block 213 is symmetrically threaded on the surface of the bidirectional screw 27. A sweeping plate 29 is slidably mounted on the top surface of the photovoltaic panel 22. A connecting rod 214 is rotatably connected to the surface of the screw block 213 through a rotating shaft. The other end of the connecting rod 214 is rotatably connected to the middle position of the sweeping plate 29. One end of the bidirectional screw 27 is fixed with an insertion block 28, and the other end of the bidirectional screw 27 is provided with an insertion hole 212. The bidirectional screws 27 of the two sets of photovoltaic modules 2 are inserted into the insertion hole 212 through the insertion block 28.

[0043] It is understandable that the mounting brackets 21 of two adjacent photovoltaic modules 2 are connected to the slots 211 by the inserts 23, and the positions of the connecting brackets 25 and the inserts 23 are fixed by the locking bolts 26. At the same time, the bidirectional screws 27 in the same row of photovoltaic modules 2 are connected by the inserts 28 and the sockets 212, realizing the connection of the bidirectional screws 27 in a row. As the bidirectional screws 27 rotate, the screw block 213 is threadedly engaged with the bidirectional screws 27, and the sweeping plate 29 is driven to slide along the slide bar 210 through the connecting rod 214 to clean the surface of the photovoltaic panel 22 and discharge the dirt accumulated on the photovoltaic panel 22 from the drain trough of the mounting bracket 21. Distributed control maintains the efficient power generation of the photovoltaic modules 2.

[0044] like Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, in some embodiments, the switching assembly 4 further includes: a first gear ring 43, a second gear ring 44, a shaft bracket 45, a first gear 46, and a second gear 47. The first gear ring 43 is fixed to the front end of the rotating disk 41, and the second gear 47 is fixed to the outer surface of the collar 42. The control box 1 is located at the bottom of the rotating disk 41 and a shaft bracket 45 is fixed thereon. The first gear 46 is rotatably mounted inside the shaft bracket 45 corresponding to the bottom of the first gear ring 43. The first gear 46 meshes with the first gear ring 43, and the second gear ring is located inside the shaft bracket 45. A second gear ring 44 is rotatably mounted on the bottom of 44, and the second gear 47 meshes with the second gear ring 44; wherein, a drive motor 48 is fixed on the outside of the control box 1 at the position corresponding to the first gear 46 and the second gear 47, an electric push rod 49 is fixed at the output end of the drive motor 48, and a protrusion 410 is symmetrically fixed at the extended end of the electric push rod 49. The first gear 46 and the second gear 47 are provided with a slot 412 at the position corresponding to the extended end of the electric push rod 49 and the protrusion 410, and the protrusion 410 is slidably engaged in the slot 412.

[0045] The power supply or distribution circuit device: It is understood that the protrusion 410 at the extended end of the electric push rod 49 can telescopically pass through the interior of the first gear 46 and the second gear 47. Through the engagement of the slot 412 and the protrusion 410, the first motor can independently drive the first gear 46 to rotate and mesh with the first gear ring 43. This, in turn, drives the switch 112 to move via the first insert plate 415, thus opening and closing the mains power transmission device 12. At this time, the protrusion 410 only engages with the slot 412 of the first gear 46. When the protrusion 410 engages with the slot 412 of the second gear 47... The first motor can drive the second gear 47 to rotate and mesh with the second gear ring 44, so that the second insert plate 418 inside the collar 42 can drive the switch 112 on one side of the energy storage device 11 to open or close. When the mains power transmission device 12 is on, the switch 112 of the energy storage device 11 can be opened at the same time to achieve coordinated power replenishment. The protrusion 410 can also be simultaneously engaged in the slot 412 of the first gear 46 and the second gear 47, so that the first gear 46 and the second gear 47 can be rotated at the same time, thereby switching the two sets of switches 112, one open and one closed.

[0046] like Figure 2 , Figure 7 and Figure 12As shown, in some embodiments, two sets of first transmission belts 31 are installed on the side of the fixing frame 3 facing the photovoltaic module 2. The pulleys of the two sets of first transmission belts 31 are fixedly connected to three rows of bidirectional screws 27 closest to the photovoltaic module 2. The two sets of first transmission belts 31 are staggered. A third gear 416 is meshed with one side of the second toothed ring 44. A connecting shaft 32 is rotatably installed on the fixing frame 3 corresponding to the position of the pulley at the outer end of the first transmission belt 31. One end of the connecting shaft 32 is fixedly connected to the pulley of the first transmission belt 31, and the other end of the connecting shaft 32 passes into the control box 1. A second transmission belt 417 is installed at the axis of the connecting shaft 32 and the third gear 416.

[0047] It should be noted that the bidirectional screws 27 of the three rows of photovoltaic modules 2 are connected by the first transmission belt 31, and the connecting shaft 32 passes into the control box 1 and is connected to the third gear 416 by the second transmission belt 417. When the second gear ring 44 rotates and meshes with the third gear 416, it drives the bidirectional screws 27 to rotate, thereby cleaning the photovoltaic panels 22 by the sweeping plate 29 on the top of the mounting bracket 21.

[0048] like Figure 7 , Figure 8 and Figure 11 As shown, in some embodiments, the transmission assembly 5 further includes: a vertical frame 54 and a plug rod 59. The vertical frame 54 is fixed to one end of the toothed plate 52 located on the back of the control box 1, and the plug rod 59 is fixed to the bottom of the vertical frame 54. The plug rod 59 slides into the interior of the control box 1. A horizontal plate 411 is fixed to the outermost end of the extended end of the electric push rod 49, and the plug rod 59 is fixedly connected to the horizontal plate 411. A limit frame 53 is provided on the top of the control box 1 corresponding to the moving path of the toothed plate 52, and the toothed plate 52 is slidably engaged inside the limit frame 53. A rotating seat 16 is fixed to the bottom of the monitoring and recognition lens 17, and the bottom of the rotating seat 16 is fixed to the fourth gear. At the top of the control box 1, heat dissipation boxes 111 are fixed on both sides of the bottom. Air vents are provided on the back of the control box 1 corresponding to the position of the heat dissipation boxes 111. A filter screen 110 is installed on the outer end of the air vents of the control box 1. A crossbeam 56 is provided on the outside of the control box 1. Scrapers 57 are fixed at the bottom of both ends of the crossbeam 56. The scrapers 57 slide along the outer surface of the filter screen 110. A pull rod 55 is rotatably connected to the inner surface of the vertical frame 54 through a pivot. The other end of the pull rod 55 is rotatably connected to the crossbeam 56 through a pivot. A second spring 58 is fixed to the top of the scraper 57. The top of the second spring 58 is fixedly connected to the back of the control box 1.

[0049] It should be noted that the cooling fan inside the heat sink 111 dissipates heat from the inside of the control box 1. Each time the output of the first motor is connected to the second gear 47 via the switching component 4, that is, when the monitoring and identification lens 17 detects that the voltage and current values ​​on the display screen 15 of the mains power transmission device 12 are insufficient, the extended end of the electric push rod 49 retracts, driving the horizontal plate 411 and the insertion rod 59 to move outward from the control box 1. At the same time, the vertical frame 54 and the toothed plate 52 move, and the toothed plate 52 moves along the limit frame 53 to engage with the fourth gear, so that the monitoring and identification lens 17 rotates to the position of the display screen 15 of the energy storage device to monitor the output of the energy storage battery and monitor the remaining power value. At the same time, as the vertical frame 54 moves, the pull rod 55 pulls the horizontal frame 56 to move, so that the scraper 57 moves along the outer wall of the control box 1 to clean the filter 110 and prevent the vents from being blocked, thus affecting heat dissipation.

[0050] Working principle:

[0051] In use, the mounting brackets 21 of two adjacent photovoltaic modules 2 are inserted into the slots 211 via the inserts 23. The positions of the connecting brackets 25 and the inserts 23 are fixed by the locking bolts 26. At the same time, the bidirectional screws 27 inside the photovoltaic modules 2 in the same row are inserted into the holes 212 via the inserts 28, realizing the connection of the bidirectional screws 27 in one row. As the bidirectional screws 27 rotate, the screw blocks 213 are threaded into the bidirectional screws 27. The connecting rod 214 drives the sweeping plate 29 to slide along the slide bar 210 to clean the surface of the photovoltaic panel 22. The dirt accumulated on the photovoltaic panel 22 is discharged from the drain trough of the mounting bracket 21. The protrusion 410 at the extended end of the electric push rod 49 can pass through the inside of the first gear 46 and the second gear 47 through the slot 4. The engagement of the 12 and the protrusion 410 allows the first motor to independently drive the first gear 46 to rotate and mesh with the first gear ring 43. This, via the first insert plate 415, moves the switch 112, enabling the mains power transmission device 12 to open and close. At this time, the protrusion 410 only engages with the slot 412 of the first gear 46. When the protrusion 410 engages with the slot 412 of the second gear 47, the first motor can drive the second gear 47 to rotate and mesh with the second gear ring 44. This causes the second insert plate 418 inside the collar 42 to open or close the switch 112 on one side of the energy storage device 11. This allows the switch 112 of the energy storage device 11 to be opened simultaneously while the mains power transmission device 12 is on, achieving coordinated energy replenishment. The protrusion 410 also... It can simultaneously engage with the slots 412 of the first gear 46 and the second gear 47, allowing simultaneous rotation of the first gear 46 and the second gear 47, thereby switching the two sets of switches 112, one open and one closed. Distributed control maintains the efficient power generation of the photovoltaic module 2. The cooling fan inside the heat sink 111 dissipates heat from the inside of the control box 1. Each time the output end of the first motor is connected to the second gear 47 via the switching component 4, i.e., when the monitoring and identification lens 17 detects that the voltage and current values ​​on the display screen 15 of the mains power transmission device 12 are insufficient, the extended end of the electric push rod 49 retracts, driving the horizontal plate 411 and the insertion rod 59 to move outwards from the control box 1. At the same time, the vertical frame 54 and the toothed plate 52 move, and the toothed plate 52 moves along the limit. The frame 53 moves and engages with the fourth engagement, causing the monitoring and identification lens 17 to rotate to the position of the display screen 15 of the energy storage device, monitoring the output of the energy storage battery and monitoring the remaining power value. At the same time, as the vertical frame 54 moves, the pull rod 55 pulls the horizontal frame 56 to move, causing the scraper 57 to move along the outer wall of the control box 1 to clean the filter screen 110 and prevent clogging of the vents from affecting heat dissipation. The first transmission belt 31 connects the bidirectional screw 27 of the three rows of photovoltaic modules 2, and the connecting shaft 32 passes into the inside of the control box 1 and is connected to the third gear 416 through the second transmission belt 417. When the second gear ring 44 rotates and engages with the third gear 416, it drives the bidirectional screw 27 to rotate, thereby cleaning the photovoltaic panel 22 by the sweeping plate 29 on the top of the mounting frame 21.
