[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0020] like Figure 1 As shown, in one embodiment, an intelligent inspection robot for photovoltaic power generation is proposed, including a control box 1, mobile crawlers 2 are arranged on both sides of the control box 1, inspection cameras 3 and obstacle avoidance radars 4 are respectively arranged on the top of the control box 1, the inner wall of the control box 1 is rotatably connected to the second rotating rod 101 and the third rotating rod 102, both sides of the inner wall of the control box 1 are fixedly connected to fixed rods 24, the second rotating rod 101 is fixedly connected to a connecting cylinder 21 on the side away from the control box 1, the outer wall of the fixing rod 24 is fixedly sleeved with conical teeth 25, the outer wall of the connecting cylinder 21 is fixedly connected to a plurality of connecting plates 22, and the connecting plate 22 is fixed on the side away from the connecting cylinder 21. A box body 23 is connected, and a plurality of suction cups 32 are connected to the outer wall of the box body 23. The end of the fixing rod 24 away from the control box 1 is rotatably sleeved on the inner wall of the connecting tube 21. A plurality of arc-shaped sheets 31 are fixedly connected to the outer wall of the box body 23. An active component for sucking and exhausting the suction cup 32 is provided inside the box body 23. A power component for driving the second rotating rod 101 and the third rotating rod 102 is provided on the control box 1. A slider 29 is slidably connected to the inner wall of the box body 23. A bidirectional threaded rod 27 is threadedly connected to the inner wall of the box body 23. A toothed disc 26 is fixedly connected to the end of the bidirectional threaded rod 27 away from the box body 23. The outer wall of the toothed disc 26 is meshed with the outer wall of the conical tooth 25.

[0021] In this embodiment, when the device is inspecting the photovoltaic panel, the device is placed on the surface of the photovoltaic panel. As the mobile crawler 2 moves, the control box 1 also moves, and the inspection camera 3 and the obstacle avoidance radar 4 start to operate. At this time, the power component is used to rotate the second rotating rod 101 and the third rotating rod 102 respectively, and the connecting cylinder 21 is driven to rotate during the rotation, and the connecting cylinder 21 drives the connecting plate 22 to rotate, and the connecting plate 22 drives the box body 23 to rotate. Since the fixed rod 24 is fixed to the inner wall of the control box 1, the connecting cylinder 21 will rotate along the fixed rod 24. Since the conical teeth 25 are fixedly sleeved on the fixed rod 24, the box body 23 drives the bidirectional threaded rod 27 to revolve along the fixed rod 24, and the bidirectional threaded rod 27 drives the toothed disc 26 to rotate. Since the conical teeth 25 of the toothed disc 26 are meshed, the bidirectional threaded rod 27 will rotate by itself, and at the same time, the box body 2 3, the slider 29 will slide along the inner wall of the box body 23, and at the same time, the air in the cavity 28 will be discharged or the air in the suction cup 32 will be sucked in. When the suction cup 32 contacts the ground, as the slider 29 slides upward, the air in the suction cup 32 will be sucked into the cavity 28, and the pressure in the suction cup 32 will be reduced, so that it is tightly attached to the surface of the photovoltaic panel, so that the whole device remains stable on the photovoltaic panel. When the two-way threaded rod 27 rotates to a certain position, the two-way threaded rod 27 rotates in the opposite direction, driving the slider 29 to push the air in the cavity 28 into the suction cup 32. At this time, the pressure in the suction cup 32 is balanced, and the suction cup 32 loses contact with the surface of the photovoltaic panel, and then the device can continue to move, avoiding the need for the robot to patrol along the four sides of the photovoltaic panel during inspection, which requires frequent movement of positions, is very laborious, and will also affect the accuracy of the detection.

[0022] A cavity 28 is provided inside the box body 23 , and an active cavity 30 is provided on the inner wall of the slider 29 . The length of the active cavity 30 is greater than the length of the bidirectional threaded rod 27 .

[0023] In this embodiment, when the slider 29 moves up and down along the inner wall of the box body 23, the length of the active cavity 30 is greater than the length of the bidirectional threaded rod 27, and the bidirectional threaded rod 27 will not pass through the slider 29, thereby preventing the gas in the cavity 28 from being discharged from the slider 29 due to the gap in the outer wall of the bidirectional threaded rod 27, thereby affecting the air tightness of the suction cup 32 and the stability of the entire device.

[0024] The power assembly includes a motor 8 fixedly connected to the inner wall of the control box 1, the output end of the motor 8 is fixedly connected to the first rotating rod 9, the second rotating rod 101 and the first rotating rod 9 are directly sleeved with a first conveyor belt 10, and the second conveyor belt 11 is sleeved between the second rotating rod 101 and the third rotating rod 102.

[0025] In this embodiment, when inspection is required, the motor 8 is started. The motor 8 drives the first rotating rod 9 to rotate, the first rotating rod 9 drives the second rotating rod 101 to rotate through the first conveyor belt 10, and the second rotating rod 101 drives the third rotating rod 102 to rotate through the second conveyor belt 11, thereby enabling the device to move stably on the photovoltaic panel.

[0026] A water tank 5 is provided on the inner wall of the control box 1, a water pipe 6 is provided at the bottom of the water tank 5, a one-way valve 7 is provided on the water pipe 6, limit blocks 15 are fixedly connected on both sides of the bottom of the control box 1, a fourth rotating rod 14 is sleeved on the end of the limit block 15 away from the control box 1, and a rotating drum 141 is fixedly connected at both ends of the fourth rotating rod 14, the rotating drum 141 is sleeved on the inner wall of the water pipe 6, and a third conveyor belt 12 is sleeved between the outer wall of the fourth rotating rod 14 and the outer wall of the third rotating rod 102.

[0027] In this embodiment, when the device is inspecting the photovoltaic panel, the device is placed on the surface of the photovoltaic panel, and water is first injected into the water tank 5. As the device moves, the one-way valve 7 is opened, and the water in the water tank 5 is discharged from the water pipe 6. At this time, the third rotating rod 102 drives the fourth rotating rod 14 to rotate through the third conveyor belt 12, and the fourth rotating rod 14 drives the rotating drum 141 to rotate.

[0028] A sealing assembly for sealing the water pipe 6 is provided on the inner wall of the rotating drum 141, a rag 13 for cleaning the surface of the photovoltaic panel is provided on the outer wall of the water pipe 6, a clamping assembly for fixing the rag 13 is provided on the control box 1, and the sealing assembly includes a fixed cylinder 17 fixedly connected to the inner wall of the rotating drum 141, a sliding column 19 slidably connected to the inner wall of the fixed cylinder 17, a spring 20 fixedly connected between the sliding column 19 and the control box 1, and water outlets 18 respectively opened on the fixed cylinder 17 and the sliding column 19, and the sliding column 19 is provided with a drainage hole matching the water outlet hole 18 and connected to the outside.

[0029] In this embodiment, when the device moves and inspects the photovoltaic panel, the fourth rotating rod 14 is driven to rotate by the third conveyor belt 12, and the fourth rotating rod 14 drives the rotating drum 141 to rotate. At this time, the one-way valve 7 is opened, and then the water in the water pipe 6 will enter the rotating drum 141. As the rotating drum 141 rotates, the sliding column 19 on the inner wall of the rotating drum 141 slides downward along the inner wall of the fixed cylinder 17 under the action of centrifugal force and compresses the spring 20. When the motor 8 on the fixed cylinder 17 and the sliding column 19 are at the same level, the water in the rotating drum 141 will be discharged from the water outlet 18 and discharged into the wiping cloth 13 from the drainage hole. The wiping cloth 13 contacts the surface of the photovoltaic panel to wipe and clean the dust on the surface of the photovoltaic panel, thereby improving the cleaning effect of the photovoltaic panel and avoiding that when the suction cup 32 contacts the surface of the photovoltaic panel, the slider 29 sucks the dust on the surface of the photovoltaic panel into the box body 23 and blocks the box body 23, thereby affecting the stability of the device when it moves on the photovoltaic panel.

[0030] The clamping assembly includes a threaded rod 16 threadedly connected to the inner wall of the control box 1, an arc-shaped clamping plate 162 rotatably connected to the bottom of the threaded rod 16, and a moving rod 161 slidably connected to the inner wall of the control box 1, and the end of the moving rod 161 away from the control box 1 is fixedly connected to the outer wall of the arc-shaped clamping plate 162.

[0031] In this embodiment, after the inspection of the photovoltaic panels is completed, when the rag 13 needs to be replaced, the threaded rod 16 is rotated. Under the limit of the moving rod 161, the threaded rod 16 drives the arc-shaped clamping plate 162 to move upward, and the arc-shaped clamping plate 162 will release the clamping of the rag 13. At this time, the rag 13 can be taken out from the water pipe 6 to complete the replacement of the rag 13.

[0032] How it works When the device is inspecting the photovoltaic panel, the device is placed on the surface of the photovoltaic panel. As the mobile crawler 2 moves, the control box 1 also moves, and the inspection camera 3 and the obstacle avoidance radar 4 start to operate. At this time, the power assembly is used to rotate the second rotating rod 101 and the third rotating rod 102 respectively, and the connecting cylinder 21 is driven to rotate during the rotation, and the connecting cylinder 21 drives the connecting plate 22 to rotate, and the connecting plate 22 drives the box body 23 to rotate. Since the fixed rod 24 is fixed to the inner wall of the control box 1, the connecting cylinder 21 will rotate along the fixed rod 24. Since the conical teeth 25 are fixedly sleeved on the fixed rod 24, the box body 23 drives the two-way The threaded rod 27 revolves along the fixed rod 24, and the two-way threaded rod 27 drives the toothed disc 26 to rotate. Since the conical teeth 25 of the toothed disc 26 are meshed, the two-way threaded rod 27 will rotate. At the same time, under the limit of the box body 23, the slider 29 will slide along the inner wall of the box body 23, and at the same time, the air in the cavity 28 will be discharged or the air in the suction cup 32 will be sucked in. When the suction cup 32 contacts the ground, as the slider 29 slides upward, the air in the suction cup 32 will be sucked into the cavity 28, and the pressure in the suction cup 32 will be reduced, so that it is closely attached to the surface of the photovoltaic panel, so that the whole device remains stable on the photovoltaic panel. When the device moves to a certain position, the bidirectional threaded rod 27 rotates in the opposite direction, driving the slider 29 to push the air in the cavity 28 into the suction cup 32. At this time, the pressure in the suction cup 32 is balanced, and the suction cup 32 loses contact with the surface of the photovoltaic panel, and then the device can continue to move. When the device moves and inspects the photovoltaic panel, the fourth rotating rod 14 is driven to rotate by the third conveyor belt 12, and the fourth rotating rod 14 drives the rotating drum 141 to rotate. At this time, the one-way valve 7 is opened, and then the water in the water pipe 6 will enter the rotating drum 141. As the rotating drum 141 rotates, the sliding column 19 on the inner wall of the rotating drum 141 moves along the fixed drum 141 under the action of centrifugal force. 7, the inner wall slides downward and compresses the spring 20. When the fixed cylinder 17 and the motor 8 on the sliding column 19 are at the same level, the water in the rotating cylinder 141 will be discharged from the water outlet 18 and discharged into the wiping cloth 13 from the drainage hole. The wiping cloth 13 contacts the surface of the photovoltaic panel to wipe and clean the dust on the surface of the photovoltaic panel, thereby improving the cleaning effect of the photovoltaic panel. The threaded rod 16 is rotated. Under the limit of the moving rod 161, the threaded rod 16 drives the arc clamping plate 162 to move upward. The arc clamping plate 162 will loosen the clamping of the wiping cloth 13. At this time, the wiping cloth 13 can be taken out from the water pipe 6 to complete the replacement of the wiping cloth 13.
