[0002] A self-propelled solar photovoltaic panel cleaning machine is an automated device specifically designed for cleaning the surface of solar photovoltaic panels. These machines achieve precise cleaning by autonomously moving and identifying the position and angle of the photovoltaic panels, combined with sensors and machine vision technology. During the cleaning process, the robot is equipped with cleaning tools such as soft brushes and water spray devices to dry-clean or wet-wash the photovoltaic panel surface to remove dirt and impurities. Simultaneously, the robot possesses intelligent sensing and autonomous navigation capabilities, enabling it to automatically follow a preset cleaning route, avoiding repeated cleaning and omissions, thereby improving cleaning efficiency.

[0003] Conventional self-propelled solar photovoltaic panel cleaning machines can move and clean photovoltaic panels with a certain degree of slope. When the spacing between photovoltaic panels is small, the device can pass through easily. However, during the installation of photovoltaic panels, a maintenance passage with larger spacing needs to be reserved. At this time, when the device moves between photovoltaic panels, it may need to be carried manually, which increases the labor intensity of the workers. Also, due to the large amplitude during the movement, the device may collide and damage the photovoltaic panels, which reduces the scope of use of the device. Therefore, there is an urgent need for a self-propelled solar photovoltaic panel cleaning machine to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-9 This utility model provides a self-propelled solar photovoltaic panel cleaning machine, including a moving main body 3 and a protective shell 4. The bottom surface of the moving main body 3 has an adjustment and storage groove 8. The front and back of the moving main body 3 are respectively fixed with connecting brackets 10, and the connecting brackets 10 are axially symmetrical about the moving main body 3. The top surface of the connecting brackets 10 has a rotating groove 14, which passes through the connecting brackets 10. The connecting brackets 10 have connecting bolts 15, which are threadedly connected to the connecting brackets 10. Positioning sensors 17 are fixed in an array on the front and back of the moving main body 3. It also includes a transition component 1, which is set in the adjustment and storage groove 8 to connect the distance between the photovoltaic panels; and a lifting component 2, which is set between the moving main body 3 and the protective shell 4 to adjust the height of the protective shell 4.

[0027] It should be noted here that the positioning sensor 17 is used to detect the gap between photovoltaic panels. As a conventional sensing component, the positioning sensor 17 is considered prior art in this application, and its working principle and operation method will not be described in detail here.

[0028] It should be noted here that the moving body 3 is composed of components such as rollers and a rolling motor. As this is prior art in this application, its working principle and operation method will not be described in detail here.

[0029] Specifically, when the device needs to move between photovoltaic panels for cleaning, the transition component 1 will build a supporting bridge between the photovoltaic panels, allowing the moving body 3 to pass quickly and smoothly. The lifting component 2 can adjust the vertical angle of the protective shell 4, avoiding collisions between the device and the photovoltaic panels during the transition movement. These designs enable the device to automatically walk on photovoltaic panels with a large gap, which not only expands the applicability of the device, but also reduces the labor intensity of the workers and improves the practicality of the device. The spacing between the positioning sensors 17 on the same surface is greater than the width of the transition plate 106, avoiding the influence of the transition plate 106 on the positioning sensors 17. The connecting bracket 10 has an axisymmetric structure about the moving body 3, so that cleaning components can be installed at both ends of the moving body 3.

[0030] The transition component 1 includes a guide frame 103, and the guide frame 103 is movably connected to the adjustment storage slot 8. The adjustment storage slot 8 is provided with a guide rod 101 and an adjustment screw 102, and the guide rod 101 and the adjustment screw 102 pass through the guide frame 103 respectively. One end of the adjustment screw 102 is fixed with an adjustment motor 104.

[0031] Specifically, driven by the adjusting motor 104, the moving screw moves the guide frame 103 left and right in the adjusting storage slot 8, while the guide rod 101 makes the guide frame 103 more stable during the movement.

[0032] The bottom surface of the guide frame 103 is provided with a transition plate 106, and the transition plate 106 is movably connected to the guide frame 103 and the transition plate 106 is movably connected to the adjustment and storage groove 8. A lifting motor 105 is fixed in the guide frame 103, and a lifting screw 107 is fixed at the output end of the lifting motor 105, and the lifting screw 107 is threadedly connected to the transition plate 106.

[0033] Specifically, when the positioning sensor 17 detects the gap between the photovoltaic panels, the transition plate 106 will move out from the adjustment and storage slot 8 to build a bridge on the top surface of the two adjacent photovoltaic panels. Then, driven by the lifting motor 105, the transition plate 106 moves downward along the guide frame 103 so that the top surface of the transition plate 106 and the bottom surface of the moving track of the moving body 3 are in the same horizontal plane. Then, supported by the transition plate 106, the moving body 3 moves while the adjustment motor 104 rotates the moving screw, realizing the transition movement of the device between the photovoltaic panels.

[0034] The lifting assembly 2 includes a support frame 201, which is fixedly connected to the protective shell 4. The surface of the support frame 201 is provided with a fixing sleeve 202, which is movably connected to the connecting bracket 10.

[0035] Specifically, after the fixing sleeve 202 on the surface of the support frame 201 is connected to the connecting bracket 10, the fixing sleeve 202 is limited by the connecting bolt 15;

[0036] A support plate 204 is fixed to the bottom surface of the support frame 201. A hydraulic rod 203 is provided on the top of the support plate 204. The hydraulic rod 203 is rotatably connected to the rotating groove 14. A universal ball 205 is fixed to the output end of the hydraulic rod 203. The universal ball 205 is movably connected to the support plate 204.

[0037] Specifically, when the protective shell 4 needs to be lifted, the universal ball 205 rotates the support frame 201 around the fixed sleeve 202 as the axis under the drive of the hydraulic rod 203. At the same time as the support frame 201 rotates, the hydraulic rod 203 rotates together in the rotating groove 14. When the device needs to clean the dust and foreign objects on the photovoltaic panel, the protective shell 4 can be adjusted to rotate downwards, and the friction force of the device during cleaning is increased by the weight of the protective shell 4 itself.

[0038] The protective shell 4 is provided with a rotating shaft 6, and the rotating shaft 6 is rotatably connected to the protective shell 4. The surface of the rotating shaft 6 is evenly provided with brushes 16. The side of the support frame 201 is fixed with a cleaning motor 11, and the output end of the cleaning motor 11 is fixedly connected to one end of the rotating shaft 6.

[0039] Specifically, when the brush 16 on the surface of the rotating shaft 6 comes into contact with the surface of the photovoltaic panel under gravity, the rotating shaft 6 drives the brush 16 to clean the surface of the photovoltaic panel under the drive of the cleaning motor 11.

[0040] An infusion tube 5 is fixed inside the protective shell 4. A nozzle 12 is fixed in an array on the bottom surface of the infusion tube 5. A scraper 13 is fixed on the bottom surface of the protective shell 4. A battery compartment 7 is opened on the top surface of the moving body 3. A cover plate 9 is provided on the top surface of the battery compartment 7, and the cover plate 9 is rotatably connected to the moving body 3.

[0041] Specifically, the device's infusion tube 5 is connected to an external high-pressure pump via a pipeline to provide cleaning fluid to the device, while the protective shell 4 and the scraper 13 on its bottom surface not only prevent the cleaning fluid from splashing but also facilitate the scraping of water stains.

[0042] Working principle: Driven by the adjusting motor 104, the moving screw carries the guide frame 103 to move left and right in the adjusting storage slot 8. The guide rod 101 makes the guide frame 103 more stable during the movement. When the positioning sensor 17 senses the gap between the photovoltaic panels, the transition plate 106 will move out from the adjusting storage slot 8 to build a bridge on the top surface of the two adjacent photovoltaic panels. Then, driven by the lifting motor 105, the transition plate 106 moves downward along the guide frame 103 so that the top surface of the transition plate 106 is on the same horizontal plane as the bottom surface of the moving track of the moving body 3. Then, supported by the transition plate 106, the moving body 3 moves while the adjusting motor 104 rotates the moving screw, realizing the transition movement of the device between the photovoltaic panels.

[0043] After the fixed sleeve 202 on the surface of the support frame 201 is connected to the connecting bracket 10, the fixed sleeve 202 is limited by the connecting bolt 15. When the protective shell 4 needs to be lifted, the universal ball 205 rotates the support frame 201 around the fixed sleeve 202 as the axis under the drive of the hydraulic rod 203. At the same time as the support frame 201 rotates, the hydraulic rod 203 rotates together in the rotating groove 14. When the device needs to clean the dust and foreign objects on the photovoltaic panel, the protective shell 4 can be adjusted to rotate downwards. The friction of the device during cleaning is increased by the gravity of the protective shell 4 itself. When the brush 16 on the surface of the rotating shaft 6 contacts the surface of the photovoltaic panel under gravity, the rotating shaft 6 drives the brush 16 to clean the surface of the photovoltaic panel under the drive of the cleaning motor 11. The device's infusion pipe 5 is connected to an external high-pressure pump through a pipeline to provide cleaning fluid to the device. The protective shell 4 and the scraper 13 on its bottom surface can not only prevent the cleaning fluid from splashing, but also facilitate the scraping of water stains.

[0044] When the device needs to move between photovoltaic panels for cleaning, the transition component 1 will build a supporting bridge between the photovoltaic panels, allowing the moving body 3 to pass quickly and smoothly. The lifting component 2 can adjust the vertical angle of the protective shell 4 to prevent the device from bumping into the photovoltaic panels during the transition. These designs allow the device to automatically walk on photovoltaic panels with a large gap, which not only expands the applicability of the device, but also reduces the labor intensity of the workers and improves the practicality of the device. The spacing between the positioning sensors 17 on the same surface is greater than the width of the transition plate 106, which prevents the transition plate 106 from affecting the positioning sensors 17. The connecting bracket 10 has an axisymmetric structure about the moving body 3, so that cleaning components can be installed at both ends of the moving body 3.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
