Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning robots, specifically an intelligent cleaning robot for outdoor photovoltaic panels. Background Technology

[0002] The photovoltaic panel intelligent cleaning robot is an intelligent robot used to clean the surface of solar photovoltaic panels. It has autonomous navigation, intelligent sensing and cleaning functions, which can improve the power generation efficiency and maintenance effect of photovoltaic panels. The photovoltaic panel intelligent cleaning robot can not only reduce the workload of manual cleaning, but also improve the cleaning effect and safety. It can work in different weather conditions, adapt to various complex environments, and can be monitored and managed in real time through remote control and monitoring systems.

[0003] Most traditional photovoltaic panel cleaning robots are pre-set to a specific size, making them unsuitable for use on both large and small photovoltaic panels. This limits their application to panels of the same size, resulting in limited applicability. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an intelligent cleaning robot for outdoor photovoltaic panels. This solves the technical problem that most current photovoltaic panel cleaning robots are pre-set in size and cannot be used on photovoltaic panels of different sizes. As a result, they can only be used on photovoltaic panels of the same size, leading to low applicability of the device.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: An intelligent cleaning robot for outdoor photovoltaic panels is designed, comprising a main body, an adjustment groove at the bottom center of the main body, two adjustment plates slidably connected within the adjustment groove, a dual-axis motor installed at the top center of the inner cavity of the adjustment groove, two drive ends of the dual-axis motor connected to lead screws, two adjustment plates threaded onto the outer sides of the two lead screws, mounting plates installed on both sides of the bottom of the two adjustment plates, a secondary brush roller rotatably connected between the two mounting plates on the same adjustment plate via a rotating shaft, an inverted L-shaped plate installed at one outer end of each of the two adjustment plates, a walking wheel rotatably connected to the inner side of each of the two inverted L-shaped plates, a first drive motor installed at one outer end of each of the two inverted L-shaped plates, the drive end of the first drive motor connected to the walking wheel, and a limit wheel rotatably connected to the bottom of each of the two inverted L-shaped plates.

[0006] Two connecting plates are installed on both sides of the bottom of the main body, and the main brush roller is rotatably connected between the two connecting plates on the same side via a rotating shaft.

[0007] Preferably, a gear post is rotatably connected between two connecting plates on one side of the main brush roller. A first gear is mounted on the outer side of the gear post, and a second gear is rotatably connected to the connecting plate on one side of the first gear. A third gear is mounted on the outer side of the rotating shaft on the main brush roller. The second gear meshes with the first and third gears. A fourth gear is mounted on the outer side of the rotating shaft on the auxiliary brush roller. A fifth gear is rotatably connected to the mounting plate on one side of the fourth gear. The fifth gear meshes with the gear post and the fourth gear. One end of the rotating shaft on the main brush roller rotatably passes through the connecting plate and is connected to a driven sprocket. A frame is mounted at the bottom of the adjusting plate, and a support sprocket is rotatably connected to the frame. A second drive motor is mounted on one side of the top of the main body. A drive sprocket is mounted on the drive end of the second drive motor. A chain connects the drive sprocket, the driven sprocket, and the support sprocket.

[0008] Preferably, guide grooves are provided on both sides of the adjusting plate, and guide blocks are slidably connected in the guide grooves, and the guide blocks are fixedly connected to the inner wall of the adjusting grooves.

[0009] Preferably, a dust sensor is installed at the bottom center of the motherboard, and the dust sensor is connected to the second drive motor through the processor.

[0010] Preferably, a solar panel is installed in the center of the surface of the main body, and a storage battery is installed on the inner side of the inverted L-shaped plate.

[0011] Preferably, a protective cover is fitted on the outside of the second drive motor, and the protective cover is connected to the main board body, with one end of the protective cover being open.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a dual-axis motor, lead screws, adjusting grooves, adjusting plates, limiting wheels, inverted L-shaped plates, mounting plates, connecting plates, main brush rollers, and auxiliary brush rollers. By starting the dual-axis motor, both lead screws rotate simultaneously. Since the adjusting block is slidably connected within the adjusting groove, the distance between the two limiting wheels can be adjusted synchronously. This allows the cleaning robot to be positioned outside the photovoltaic panel's mounting frame according to the panel's size, ensuring the walking wheels contact the surface of the mounting frame. Then, starting the first drive motor rotates the drive wheels, moving the cleaning robot across the photovoltaic panel. Because the main and auxiliary brush rollers are staggered, they can be used to clean photovoltaic panels of different sizes, enabling the cleaning of photovoltaic panels of varying dimensions.

[0014] 2. This utility model combines a second drive motor, a first gear, a second gear, a third gear, a fourth gear, a fifth gear, a gear post, a driving sprocket, a driven sprocket, a support sprocket, and a chain. When the cleaning robot moves, starting the second drive motor can simultaneously drive the main brush roller and the auxiliary brush roller to rotate, thereby improving the cleaning effect of the photovoltaic panel. When the adjustment plate is adjusted, the fifth gear is always engaged with the gear post, so that when cleaning photovoltaic panels of different sizes, the second drive motor can also simultaneously drive the main brush roller and the auxiliary brush roller to rotate and clean the photovoltaic panels.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: An intelligent cleaning robot for outdoor photovoltaic panels, see [link to example]. Figures 1 to 5The system includes a main body 1. An adjustment groove 25 is formed at the bottom center of the main body 1. Two adjustment plates 2 are slidably connected within the adjustment groove 25. A dual-axis motor 26 is installed at the top center of the inner cavity of the adjustment groove 25. Both drive ends of the dual-axis motor 26 are connected to lead screws 27. The two adjustment plates 2 are threaded onto the outer sides of the two lead screws 27. Mounting plates 21 are installed on both sides of the bottom of the two adjustment plates 2. A secondary brush roller 22 is rotatably connected between the two mounting plates 21 on the same adjustment plate 2 via a rotating shaft. An inverted L-shaped plate 3 is installed at one outer end of each of the two adjustment plates 2. A traveling wheel 32 is rotatably connected to the inner side of each of the two inverted L-shaped plates 3. A first drive motor 31 is installed at one outer end of each of the two inverted L-shaped plates 3. The drive end of the first drive motor 31 is connected to the traveling wheel 32. A limit wheel 33 is rotatably connected to the bottom of each of the two inverted L-shaped plates 3. Two connecting plates 11 are installed on both sides of the bottom. The two connecting plates 11 on the same side are rotatably connected to the main brush roller 12 via a rotating shaft. During operation, the dual-axis motor 26 is started to drive the two lead screws 27 to rotate simultaneously. Since the adjusting block is slidably connected in the adjusting groove 25, the distance between the two limiting wheels 33 can be adjusted synchronously. Thus, the cleaning robot can be limited to the outside of the photovoltaic panel mounting frame by the limiting wheels 33 according to the size of the photovoltaic panel, and the walking wheel 32 is made to contact the surface of the photovoltaic panel mounting frame. Then, the first drive motor 31 is started to drive the drive wheel to rotate, thereby driving the cleaning robot to move on the photovoltaic panel. Since the main brush roller 12 and the auxiliary brush roller 22 are staggered, the main brush roller 12 and the auxiliary brush roller 22 can be used to clean photovoltaic panels of different sizes, and can further clean photovoltaic panels of different sizes.

[0023] For details, see Figure 2 — Figure 5A gear post 79 is rotatably connected between two connecting plates 11 on one side of the main brush roller 12. A first gear 78 is mounted on the outside of the gear post 79. A second gear 77 is rotatably connected to the connecting plate 11 on one side of the first gear 78. A third gear 76 is mounted on the outside of the rotating shaft on the main brush roller 12. The second gear 77 meshes with the first gear 78 and the third gear 76. A fourth gear 711 is mounted on the outside of the rotating shaft on the auxiliary brush roller 22. A fifth gear 710 is rotatably connected to the mounting plate 21 on one side of the fourth gear 711. The fifth gear 710 meshes with the gear post 79 and the fourth gear 711. One end of the rotating shaft on the main brush roller 12 rotatably passes through the connecting plate 11 and is connected to a driven sprocket 75. A frame 73 is mounted at the bottom of the adjusting plate 2. A support sprocket 74 is rotatably connected to the frame 73. A second drive motor 7 is mounted on one side of the top of the main body 1. A drive sprocket 71 is mounted on the drive end of the second drive motor 7. The drive sprocket 71, the driven sprocket 75, and... A chain 72 connects the support sprockets 74. When the cleaning robot moves, the second drive motor 7 is activated to drive the active sprocket 71 to rotate. This, in conjunction with the driven sprocket 75 and the support sprockets 74, drives the two main brush rollers 12 to rotate. When the main brush rollers 12 rotate, they drive the third gear 76 to rotate. The third gear 76 drives the second gear 77 to rotate. The second gear 77 drives the first gear 78 to rotate, which in turn drives the gear post 79 to rotate. Since the fifth gear 710 meshes with the gear post 79 and the fourth gear 711, it drives the two auxiliary brush rollers 22 to rotate. Thus, the second drive motor 7 can simultaneously drive the main brush rollers 12 and the auxiliary brush rollers 22 to rotate, thereby improving the cleaning effect of the photovoltaic panels. When the adjustment plate 2 is adjusted, the fifth gear 710 always meshes with the gear post 79. Therefore, when cleaning photovoltaic panels of different sizes, the second drive motor 7 can also simultaneously drive the main brush rollers 12 and the auxiliary brush rollers 22 to rotate and clean the photovoltaic panels.

[0024] Further, see Figure 1 Guide grooves 23 are provided on both sides of the adjustment plate 2. Guide blocks 24 are slidably connected in the guide grooves 23 and are fixedly connected to the inner wall of the adjustment groove 25. The adjustment is guided and limited by the guide grooves 23 and the guide blocks 24, thereby improving the stability of the connection between the adjustment plate 2 and the main body 1 and further improving the overall stability of the cleaning robot operation.

[0025] It is worth noting that, see Figure 2 A dust sensor 6 is installed at the bottom center of the main body 1. The dust sensor 6 is connected to the second drive motor 7 through the processor. The dust sensor 6 can detect the dust concentration on the surface of the photovoltaic panel. When the dust concentration on the surface of the photovoltaic panel is greater than the threshold set by the dust sensor 6, the second drive motor 7 is started to drive the main brush roller 12 and the auxiliary brush roller 22 to rotate and automatically clean the photovoltaic panel.

[0026] It is worth noting that, see Figure 1 and Figure 3 A solar panel 41 is installed in the middle of the surface of the main body 1, and a battery 4 is installed on the inner side of the inverted L-shaped plate 3. A solar controller is connected between the solar panel 41 and the battery 4. An inverter is connected between the battery 4 and the first drive motor 31, the second drive motor 7 and the dual-axis motor 26. The solar panel 41 facilitates the charging of the battery 4, and the battery 4 stores electrical energy and works with the inverter to provide power to the first drive motor 31, the second drive motor 7 and the dual-axis motor 26 for operation.

[0027] It is worth mentioning that, see Figure 3 The second drive motor 7 is fitted with a protective cover 5 on its outer side, and the protective cover 5 is connected to the main board 1. One end of the protective cover 5 is open. The protective cover 5 can protect the chain 72, thereby preventing the chain 72 from rusting, increasing friction and energy consumption. The fact that one end of the protective cover 5 is open does not affect the heat dissipation of the second drive motor 7 during operation.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
