Description

Technical Field

[0001] This utility model relates to the field of cleaning robot technology, and in particular to an intelligent automatic photovoltaic panel cleaning robot. Background Technology

[0002] Smart photovoltaic panels integrate advanced semiconductor materials, high-efficiency battery manufacturing processes, and intelligent control systems. They can automatically adjust their angle and monitor power generation status in real time, significantly improving photoelectric conversion efficiency. However, during use, surface dirt can block sunlight, reduce power generation efficiency, lead to energy loss, increase maintenance costs, shorten equipment lifespan, and exacerbate environmental impact. Therefore, cleaning is crucial.

[0003] For example, CN207339779U discloses a large-scale intelligent cleaning robot for solar photovoltaic panels, including a rectangular frame, a control box, and a rectangular frame comprising a high arm and a low arm. A roller brush is located between the high and low arms, and a roller brush motor is mounted on the high arm. Both ends of the high and low arms have wheels, and a wheel motor is installed on the low arm's wheels. Hanging wheels are also installed under the high arm. Each hanging wheel comprises a cylinder and a frustum, and an axle passing through the axes of the cylinder and the frustum. The small plane of the frustum is in close contact with the plane of the cylinder. The cylinder is made of an elastic material. The height of the cylinder is equal to or slightly greater than the side height of the photovoltaic panel. A hanging wheel motor is installed on each hanging wheel. Two auxiliary wheels are installed under the low arm. Each auxiliary wheel comprises a cylinder and an axle, and the cylinder rotates freely around the axle.

[0004] However, in existing technologies, when installing and using smart photovoltaic panels, on the one hand, in order to make them as perpendicular to the sunlight as possible to reduce shading and improve power generation efficiency and solar energy utilization; on the other hand, to facilitate drainage and self-cleaning, reduce the impact of snow and water accumulation, facilitate heat dissipation to reduce safety hazards, and adapt to complex terrain and space requirements, smart photovoltaic panels are often installed at an angle according to the environmental conditions of the area. Due to the tilt of the photovoltaic panels, the pressure distribution of the cleaning robot on the surface of the photovoltaic panel changes under the action of gravity. On the slope, the robot's center of gravity will shift, resulting in uneven pressure between the cleaning cloth and the photovoltaic panel, leading to insufficient cleaning. At the same time, the tilted photovoltaic panels increase the difficulty of the cleaning robot's movement and affect its stability. The robot needs to overcome the effects of gravity and slope friction to maintain balance and walk stably. If the robot's walking mechanism is not designed reasonably or lacks effective anti-slip and anti-tipping measures, it is easy to slip, sway, or even fall when walking on the slope. This will not only affect the cleaning effect but may also damage the robot or the photovoltaic panel. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-4 As shown, this utility model provides an intelligent photovoltaic panel automatic cleaning robot, including a walking mechanism 1. A first fixed frame 2 is fixedly connected to the upper part of the walking mechanism 1. A first electric push rod 3 is fixedly connected to the upper part of the first fixed frame 2. A first connecting plate 5 is fixedly connected to the upper part of the first electric push rod 3. A second fixed frame 6 is fixedly connected to the upper part of the first connecting plate 5. A moving mechanism 7 is fixedly connected to the bottom of the second fixed frame 6. An angle adjustment mechanism 8 is fixedly connected to the bottom of the moving mechanism 7. The angle adjustment mechanism 8 includes a second connecting plate 81 and a connecting shaft 88. A mounting frame 82 is fixedly connected to the bottom of the second connecting plate 81. A second electric push rod 83 is fixedly connected to the side of the mounting frame 82. A third connecting plate 84 is fixedly connected to the output end of the second electric push rod 83. A rack 85 is fixedly connected to the side of the third connecting plate 84. The connecting shaft 88 is rotatably connected to the bottom of the second connecting plate 81. A gear 87 is fixedly connected to the end of the connecting shaft 88, and the gear 87 meshes with the rack 85. A cleaning mechanism 9 is installed on the surface of the connecting shaft 88. A limit frame 86 is fixedly connected to the bottom of the second connecting plate 81. The upper part of the rack 85 is located inside the limit frame 86, and the rack 85 is slidably connected to the limit frame 86. A limit rod 4 is fixedly connected to the upper surface of the first fixed frame 2, and the limit rod 4 is slidably inserted into the first connecting plate 5. The moving mechanism 7 includes a servo motor 71, which is fixedly connected to the second fixed frame 6. A lead screw 72 is fixedly connected to the output end of the servo motor 71. A lead block 73 is threadedly connected to the surface of the lead screw 72. The lead block 73 is fixedly connected to the second connecting plate 81 and rotatably connected to the surface of the second fixed frame 6. A slide rail 74 is fixedly connected to the bottom of the second fixed frame 6. A slider 75 is slidably connected to the surface of the slide rail 74 and is fixedly connected to the second connecting plate 81.

[0025] The specific settings and functions of this embodiment are described below. The walking mechanism 1 drives the entire unit to move, moving the cleaning mechanism 9 to the upper part of the smart photovoltaic panel to be cleaned. Then, according to the tilt angle of the smart photovoltaic panel, the telescopic second electric push rod 83 drives the third connecting plate 84 to move, thereby driving the rack 85 to slide along the limit frame 86, which in turn drives the gear 87 to rotate. Finally, the angle of the connecting shaft 88 and the cleaning mechanism 9 mounted on its surface is adjusted so that the angle of the cleaning mechanism 9 matches the cutting angle of the smart photovoltaic panel. Then, the height of the cleaning mechanism 9 is adjusted by the telescopic first electric push rod 3 so that the cleaning mechanism 9 fits against the surface of the smart photovoltaic panel to clean the surface of the smart photovoltaic panel.

[0026] The telescopic electric push rod 83 drives the connecting plate 84, rack 85, gear 87 and connecting shaft 88 to adjust the angle of the cleaning mechanism 9 so that it matches the tilt angle of the photovoltaic panel. This solves the problem of uneven pressure between the cleaning cloth and the photovoltaic panel caused by the tilt of the photovoltaic panel, and enables more thorough cleaning of the photovoltaic panel surface.

[0027] Simultaneously, the servo motor 71 drives the lead screw 72 to rotate, thereby moving the lead block 73 and the angle adjustment mechanism 8 installed below it, which in turn moves the cleaning mechanism 9 along the surface of the smart photovoltaic panel to perform a comprehensive and thorough cleaning of the smart photovoltaic panel surface. During the process of the lead block 73 moving the angle adjustment mechanism 8, the slider 75 slides along the slide rail 74 to limit the movement of the angle adjustment mechanism 8, thereby improving the stability of the angle adjustment mechanism 8 during movement, and thus improving the stability of the cleaning mechanism 9 when cleaning the surface of the smart photovoltaic panel.

[0028] Example 2: Figures 1-4 As shown, a water supply mechanism 10 is fixedly connected to the upper part of the second fixed frame 6. A connecting pipe 11 is installed on the upper part of the water supply mechanism 10. A nozzle 12 is fixedly connected to the end of the connecting pipe 11. The nozzle 12 is installed on the side of the cleaning mechanism 9.

[0029] The overall effect of this embodiment is that, during the cleaning process of the smart photovoltaic panel using the cleaning mechanism 9, the surface of the smart photovoltaic panel can be rinsed through the water supply mechanism 10, the connecting pipe 11 and the nozzle 12, which, in conjunction with the cleaning operation of the cleaning mechanism 9, further improves the cleanliness of the smart photovoltaic panel surface after cleaning.

[0030] The device is used and works as follows: The walking mechanism 1 moves the entire unit to move the cleaning mechanism 9 to the upper part of the smart photovoltaic panel to be cleaned. Then, according to the tilt angle of the smart photovoltaic panel, the telescopic electric push rod 83 moves the connecting plate 84, which in turn moves the rack 85 along the limit frame 86, thereby driving the gear 87 to rotate. Finally, the angle of the connecting shaft 88 and the cleaning mechanism 9 mounted on its surface is adjusted so that the angle of the cleaning mechanism 9 matches the tilt angle of the smart photovoltaic panel. Then, the height of the cleaning mechanism 9 is adjusted by the telescopic electric push rod 3 so that the cleaning mechanism 9 fits against the surface of the smart photovoltaic panel to clean the surface of the smart photovoltaic panel.

[0031] At the same time, the servo motor 71 drives the lead screw 72 to rotate, thereby driving the lead block 73 and the angle adjustment mechanism 8 installed below it to move, which in turn drives the cleaning mechanism 9 to move along the surface of the smart photovoltaic panel.

[0032] During the cleaning process of the smart photovoltaic panel using the cleaning mechanism 9, the surface of the smart photovoltaic panel can be rinsed through the water supply mechanism 10, the connecting pipe 11 and the nozzle 12. In conjunction with the cleaning operation of the cleaning mechanism 9, the cleanliness of the smart photovoltaic panel surface after cleaning is further improved.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way.
