[0002] With the rapid development of photovoltaic power generation technology, the scale and number of photovoltaic power plants are constantly increasing. As the core component of a photovoltaic power plant, the surface cleanliness of photovoltaic panels directly affects power generation efficiency. However, photovoltaic panels, exposed to the outdoor environment for extended periods, easily accumulate dust, bird droppings, and other contaminants, leading to a decrease in photoelectric conversion efficiency. Therefore, regular cleaning of photovoltaic panels is a crucial aspect of the operation and maintenance of photovoltaic power plants.

[0003] Existing photovoltaic panel cleaning equipment is mostly fixed or semi-automated, which has the following problems: First, the equipment is complex to install, making it difficult to quickly disassemble and adapt to photovoltaic panel frames of different specifications; second, the movement and positioning accuracy of the cleaning device is low, making it difficult to ensure effective contact between the cleaning brush and the photovoltaic panel; third, the adjustment mechanism is complex, inconvenient to operate, and increases the labor intensity of maintenance personnel. Therefore, a simple, easy-to-install, and flexible detachable cleaning tool is needed to improve the operation of photovoltaic power plants. Utility Model Content

[0004] The purpose of this invention is to provide a detachable cleaning tool for the operation and maintenance of photovoltaic power plants, which can effectively solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The device includes a mounting frame and a cleaning structure mounted on the mounting frame. The mounting frame is provided with a moving wheel and a limiting wheel at its lower end. The moving wheel has a vertical axis and rolls on the upper surface of the photovoltaic panel frame. The limiting wheel has a horizontal axis and rolls on the front and rear end faces of the photovoltaic panel frame. The mounting frame is also provided with an adjustment device to control the limiting wheel to press against the front and rear end faces of the photovoltaic panel frame.

[0007] Furthermore: the number of limiting wheels is four, distributed in pairs on the front and rear ends of the photovoltaic panel frame; the mounting frame has two mounting strips on one side and two mounting frames on the other side, one of the mounting strips and the other mounting frame is located near the rear end of the photovoltaic panel frame, and the other mounting strip and the other mounting frame is located near the front end of the photovoltaic panel frame; each mounting strip and the mounting frame has a limiting wheel rotatably mounted at its lower end via a pivot; the adjustment device is located on the mounting strip and the mounting frame at the front end of the photovoltaic panel frame.

[0008] Furthermore: the adjustment device includes an adjustment groove disposed on the mounting strip and the mounting frame, the adjustment groove passing through the upper and lower end faces of the mounting strip and the mounting frame; an adjustment block is slidably disposed in the adjustment groove, the lower end of the adjustment block is fixedly connected to the rotating shaft, a limit plate is disposed at the upper end of the adjustment block, and an adjustment bolt is disposed in the adjustment groove, the adjustment block and the adjustment bolt being threadedly connected.

[0009] Furthermore, an operating ring is also provided at the end of the adjusting bolt.

[0010] Furthermore: the cleaning structure 2 includes a first horizontal plate 15, a second horizontal plate 16, and a third horizontal plate 17 disposed on the mounting frame. The first horizontal plate 15 is hollow inside and is provided with an air guide pipe 18, and air jets 19 are evenly arranged at the lower end of the air guide pipe 18. The second horizontal plate 16 is hollow inside and is provided with a water guide pipe 20, and water spray heads 21 are evenly arranged at the lower end of the water guide pipe 20. A cleaning wipe 22 is disposed at the lower end of the third horizontal plate 17.

[0035] See Figure 1-9 This invention relates to an embodiment of a detachable cleaning tool for photovoltaic power plant operation and maintenance, aiming to provide a simple, easy-to-install, precise-positioning, and highly automated solution for cleaning photovoltaic panels. The structure and working principle of the invention are described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 , Figure 4As shown, the cleaning tool in this embodiment includes a mounting frame 1 and a cleaning structure 2 fixedly disposed below the mounting frame 1. The mounting frame 1 is the main frame of the cleaning structure 2 and is made of lightweight, high-strength aluminum alloy. The cleaning structure 2 is used to clean the surface of photovoltaic panels.

[0037] The lower end of the mounting frame 1 is equipped with moving wheels 4 and limiting wheels 5 for supporting and positioning the cleaning structure 2. The moving wheels 4 are vertically oriented and roll on the upper surface of the photovoltaic panel frame 6 to achieve smooth movement of the cleaning structure 2. The limiting wheels 5 are horizontally oriented and roll in contact with the front and rear end faces of the photovoltaic panel frame 6 to prevent the cleaning structure 2 from shifting forward or backward during movement. The mounting frame 1 is also equipped with an adjustment device 7 to adjust the contact pressure between the limiting wheels 5 and the front and rear end faces of the photovoltaic panel frame 6 to accommodate photovoltaic panel frames of different thicknesses and specifications, and also to facilitate the removal of the entire cleaning device from the photovoltaic panel frame 6.

[0038] Limit wheel 5 and adjustment device:

[0039] There are four limiting wheels 5, divided into two groups of two, distributed at the front and rear ends of the photovoltaic panel frame 6 to ensure the stable positioning of the cleaning structure 2 in the front-rear direction. Different mounting structures are provided on both sides of the mounting frame 1: two mounting strips 8 are fixed on one side, and two mounting frames 9 are fixed on the other side. The mounting strips 8 and mounting frames 9 near the rear end of the photovoltaic panel frame 6 are each rotatably connected to a limiting wheel 5 via a pivot 10, and the mounting strips 8 and mounting frames 9 near the front end are also connected to a limiting wheel 5 via a pivot 10. The mounting strips 8 are elongated structures providing stable support; the mounting frames 9 are frame-like structures that serve both to support and accommodate other components.

[0040] like Figure 2 , Figure 3As shown, the main function of the adjustment device 7 is to achieve stable positioning of the mounting frame 1 on the photovoltaic panel frame 6 by precisely controlling the clamping force between the limiting wheel 5 and the front and rear end faces of the photovoltaic panel frame 6, while also facilitating the quick installation and disassembly of the mounting frame 1. Specifically, the adjustment device 7 includes an adjustment groove 71 located on the mounting strip 8 and mounting frame 9 at the front end of the photovoltaic panel frame 6, an adjustment block 72 slidably disposed in the adjustment groove 71, a limiting plate 73 fixed to the upper end of the adjustment block 72, and an adjustment bolt 74 threadedly connected to the adjustment block 72. By rotating the adjustment bolt 74 (which has an operating ring 75 at its end for easy manual operation), the adjustment block 72 can be driven to slide along the adjustment groove 71, thereby adjusting the position of the limiting wheel 5 connected to the lower end of the adjustment block 72 via the rotating shaft 10, so that the contact force between the limiting wheel 5 and the front end face of the photovoltaic panel frame 6 is moderate. This adjustment mechanism ensures that the limit wheel 5 fits tightly against the front face of the frame during the cleaning process, preventing the mounting bracket 1 from shifting back and forth. At the same time, it allows maintenance personnel to quickly release the clamping force by loosening the adjusting bolt 74 after cleaning, thereby easily removing the mounting bracket 1 from the photovoltaic panel frame 6, facilitating the transfer and storage of tools.

[0041] Drive unit:

[0042] like Figure 5 As shown, the mounting frame 1 is also equipped with a drive device for driving the moving wheel 4 to move along the upper surface of the photovoltaic panel frame 6, thereby automating the operation of the cleaning structure 2. The drive device includes a drive motor 11, a first pulley transmission mechanism 12, and a transmission rod 13. The drive motor 11 is fixed on the mounting frame 1 and is a DC motor. The output shaft of the drive motor 11 transmits power to the transmission rod 13 through the first pulley transmission mechanism 12. The transmission rod 13 is a long strip of metal rod that extends along the length of the mounting frame 1, with both ends connected to the shafts of the moving wheel 4, driving the moving wheel 4 to roll through rotation.

[0043] The movable wheels 4 are divided into two types: driving wheels 41 and driven wheels 42. There are four driving wheels 41, arranged in pairs in the two mounting frames 9, directly receiving power from the drive rod 13. There are two driven wheels 42, each mounted on one of the two mounting strips 8, serving only a supporting and rolling function, without direct connection to the drive device. Both driving wheels 41 and driven wheels 42 are made of wear-resistant rubber or polyurethane material to increase friction with the upper surface of the photovoltaic panel frame 6 and prevent slippage.

[0044] To ensure the synchronization of the two drive wheels 41, a second pulley transmission mechanism 14 is provided between two adjacent drive wheels 41. The second pulley transmission mechanism 14 includes a pulley and a transmission belt, which transmits the rotation of one drive wheel 41 to the other drive wheel 41 through belt transmission, ensuring that the cleaning structure 2 remains stable during movement and avoiding tilting or shaking caused by inconsistent wheel speeds.

[0045] Cleaning structure 2:

[0046] It is a core component for achieving surface cleaning of photovoltaic panels. For example... Figure 6 As shown, the cleaning structure 2 includes a first horizontal plate 15, a second horizontal plate 16, and a third horizontal plate 17, which are arranged sequentially along the moving direction of the mounting frame 1 to form a multi-level cleaning system. The cleaning effect is ensured through the synergistic effect of air jet, water jet, and physical scrubbing.

[0047] See Figure 7 The first horizontal plate 15 is fixed on the mounting frame 1 and located at the front end of the cleaning structure 2. Its interior is hollow, forming a cavity to accommodate the air guide pipe 18. The air guide pipe 18 extends along the length of the first horizontal plate 15, with multiple jet nozzles 19 evenly arranged at its lower end. The jet nozzles 19 are connected to the air guide pipe 18, which is connected to an external air pump via an air supply pipe to supply high-pressure airflow. The jet nozzles 19 direct the airflow, performing a preliminary cleaning of the photovoltaic panel surface, removing loose dust and particles, thus reducing the burden on subsequent cleaning steps.

[0048] See Figure 8 , Figure 9 The second horizontal plate 16 is located behind the first horizontal plate 15 and is also fixed to the mounting bracket 1. It is hollow inside and contains a built-in water guide pipe 20. The water guide pipe 20 is arranged along the length of the second horizontal plate 16, with multiple spray nozzles 21 evenly distributed at its lower end. The water guide pipe 20 is connected to an external water pump via a water supply pipe to supply cleaning water or cleaning solution. The spray nozzles 21 spray water downwards to wet and rinse the photovoltaic panel surface, softening and removing stubborn stains. In addition, a brush 23 is also provided at the lower end of the second horizontal plate 16. The brush 23 is installed away from the spray nozzles 21 to ensure that the water spraying function is not interfered with. The brush 23 is made of a flexible and wear-resistant material (such as nylon) and gently brushes the photovoltaic panel surface while spraying water, further improving the cleaning effect.

[0049] The third horizontal plate 17 is located behind the second horizontal plate 16 and serves as the end component of the cleaning structure 2, fixed to the mounting bracket 1. A cleaning wipe 22 is provided at its lower end. The cleaning wipe 22 is made of a highly absorbent and wear-resistant material (such as microfiber cloth or sponge) to remove residual water stains and fine dirt through physical wiping, ensuring the photovoltaic panel surface is dry and clean, and preventing watermarks from affecting photovoltaic efficiency.

[0050] Working principle: As the cleaning tool moves along the photovoltaic panel frame 6, the cleaning structure 2 operates in the following sequence: First, the jet nozzles 19 of the first horizontal plate 15 spray high-pressure airflow to blow away loose dust from the photovoltaic panel surface; then, the water spray nozzles 21 of the second horizontal plate 16 spray water to wet the surface, while the brushes 23 simultaneously brush gently to remove stubborn stains; finally, the cleaning wipes 22 of the third horizontal plate 17 wipe the surface and absorb the water, completing the cleaning process. This three-stage cleaning system works in tandem, significantly improving cleaning efficiency and quality.

[0051] Advantages: The cleaning structure 2 uses a comprehensive cleaning method of air, water, and wiping, which has higher cleaning power and adaptability than a single brushing method, and can deal with different types of dirt.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
