[0048] Embodiment 1

[0049] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a solar panel cleaning device comprises a main support 1, a moving wheel 2 and a cleaning part 3. The moving wheel 2 is arranged on the first side of the main support 1 and protrudes from the main support 1. The axis of the moving wheel 2 is perpendicular to the plane on which the main support 1 is located. The cleaning part 3 is installed on the main support 1. The moving wheel 2 can be clamped on the side wall of the frame 4 of the solar panel 5 and moved along the extension direction of the side wall of the frame 4.

[0050] The main support 1 refers to the main frame 4 structure that supports and connects various components of the solar panel 5 cleaning device. Its role is to ensure the stability of the entire device during movement and provide sufficient strength to withstand the influence of external environment (such as wind force) and the pressure of its own weight and additional components. Specifically, the shape of the main support 1 can vary according to specific application requirements. For example, the main support 1 can be linear, suitable for shorter solar panel 5 arrays, simple in structure and easy to manufacture. The main support 1 can also be a frame 4 type, forming a closed or polygonal frame 4, such as a rectangular frame 4, which is in contact with the top and bottom of the solar panel 5 at both ends, providing better stability for the device, suitable for large-scale or complex terrain applications. The main support 1 is made of aluminum alloy, stainless steel and other materials, which have good corrosion resistance, light weight and high strength. The main support 1 can be connected by welding, bolt fixing and other methods to ensure the firmness and detachability of the structure. For longer or larger supports, cross beams or other forms of support may be needed to enhance the overall rigidity.

[0051] Specifically, the main support 1 can be an adjustable main support 1, with adjustable height or angle, to adapt to different specifications of solar panels 5 or special terrain conditions. For example, the rod in the length direction of the main support 1 can be a telescopic rod or a mechanical lead screw to adapt to solar panels 5 of different widths or heights in inclined state.

[0052] The mobile wheel 2 is a rotating component installed at the bottom of a mechanical device or apparatus, which is used to enable the entire apparatus to move smoothly along a predetermined path or ground. In the solar cell panel 5 cleaning apparatus, the main function of the mobile wheel 2 is to enable the apparatus to move along the side wall of the solar cell panel 5 frame 4, ensuring that the cleaning part 3 can cover the entire surface of the solar cell panel 5, while maintaining the stability and accuracy of the apparatus. The wheel body of the mobile wheel 2 can be made of wear-resistant and corrosion-resistant materials such as polyurethane, nylon, or rubber. The shape of the mobile wheel 2 is circular, and the diameter and width are designed according to the size of the solar cell panel 5 frame 4. The wheel shaft of the mobile wheel 2 is installed vertically on the plane where the main support 1 is located, ensuring that the wheel can move smoothly along the side wall of the frame 4. The bearing of the mobile wheel 2 is used to support the wheel 6 shaft, reduce friction, and improve rotation efficiency, and the bearing type can be a ball bearing or a needle bearing. The wheel carrier of the mobile wheel 2 is connected to the wheel shaft for installation and fixation of the wheel body, and the wheel carrier is made of metal materials such as aluminum alloy and stainless steel, ensuring the strength and stability of the structure.

[0053] The mobile wheel 2 can also be provided with a height adjustment mechanism, such as a threaded rod, a spring, or other adjustment devices, which can adjust the height of the wheel to ensure that the wheel can closely fit the side wall of the frame 4. The mobile wheel 2 can also be provided with a tension adjustment mechanism, such as the use of the elastic deformation of a spring to adjust the pressure between the wheel and the track, or the use of a hydraulic system to adjust the pressure between the wheel and the track, thereby adjusting the pressure between the wheel and the side wall of the frame 4, ensuring the stability of the apparatus during movement.

[0054] The mobile wheel 2 can be connected to the main support 1 by a fixed method, which does not allow the position of the wheel relative to the main support 1 to change. Its structure is simple, easy to install, and stable, and it is not easy to loosen. Specifically, a connecting rod 7 perpendicular to the main support 1 can be fixedly connected to the main support 1, and the wheel carrier can be fixed to one end of the connecting rod 7 using bolts and nuts or welded together with the connecting rod, and the wheel shaft is perpendicular to the main support 1. Alternatively, the wheel carrier can not be provided, only the bearing is provided, and the wheel shaft is directly connected to the main support 1. A motor can also be provided, which is fixed to the main support 1, and the output end of the motor is connected to the wheel shaft.

[0055] The mobile wheel 2 can also be connected to the main support 1 in an adjustable manner, allowing the position and angle of the wheel to be adjusted, which has strong adaptability and can adjust the position and pressure of the wheel to adapt to solar cell panel frames 4 of different sizes and shapes. Specifically, the position of the wheel carrier can be adjusted by rotating a threaded rod, thereby changing the pressure between the wheel and the track; the elastic deformation of a spring can also be used to adjust the pressure between the wheel and the track; a manual knob can also be used to adjust the position of the wheel carrier, thereby changing the pressure between the wheel and the track; and a hydraulic system can also be used to adjust the pressure between the wheel and the track.

[0056] By the above technical solution, the solar panel cleaning device provided by the present disclosure is characterized in that the moving wheel 2 protruding from the main support 1 is arranged on the first side of the main support 1, and the axis of the moving wheel 2 is perpendicular to the plane on which the main support 1 is located, so that the moving wheel 2 can be clamped on the side wall of the frame 4 of the solar panel 5, thereby suspending the device on the top of the solar panel 5 in an inclined state, and moving along the extension direction of the side wall of the frame 4, and the cleaning device arranged on the main support 1 can clean the inclined solar panel 5 used outdoors comprehensively without changing the structure of the solar panel 5.

[0057] As shown in Figure 2 some embodiments, the solar panel 5 cleaning device further comprises a support wheel 6 arranged on the first side of the main support 1, and the axis of the support wheel 6 is parallel to the plane on which the main support 1 is located, so that the support wheel 6 can contact the frame 4 of the solar panel 5 and move along the extension direction of the side wall of the frame 4.

[0058] The support wheel 6 is a rotating component installed on the main support 1 of the solar panel 5 cleaning device, and its main function is to provide additional support and stability to ensure that the device does not shake or deviate from the track during movement. The support wheel 6 is arranged on the other side adjacent to the side wall of the main support 1, and can contact the side of the other side of the frame 4 of the solar panel 5, i.e., the plane on which the solar panel 5 is located, thereby providing support for the main support 1. Specifically, the structure of the support wheel 6 can be the same as that of the moving wheel 2. The support wheel 6 can be connected to a rod or plate extending from the first side of the main support 1, and the rotating shaft of the support wheel 6 is fixedly connected or adjustably connected to the extending plate or rod, and the axis of the rotating shaft, i.e., the axis of the support wheel 6, is parallel to the plane on which the main support 1 is located, so that the bottom end of the support wheel 6 can contact the side of the frame 4 of the solar panel 5 to provide support, and can also move along the extension direction of the side wall of the frame 4, thereby improving the stability during movement.

[0059] As shown in Figure 2 some embodiments, the solar panel 5 cleaning device further comprises a connecting rod 7, which is perpendicular to the plane on which the main support 1 is located, and the first end of the connecting rod 7 is connected to the main support 1, the second end of the connecting rod 7 is provided with the moving wheel 2, and the support wheel 6 is arranged on the side wall of the connecting rod 7. Specifically, the connecting rod 7 is made of a metal material (such as aluminum alloy, stainless steel) to ensure the strength and stability of the structure. It can be a straight rod or have a bending shape as needed to better adapt to the structure of the frame 4 of the solar panel 5. By integrating the moving wheel 2 and the support wheel 6 on the same connecting rod 7, the cost can be saved, the space can be optimized, and the stability of the solar panel cleaning device can be significantly improved, thereby ensuring the smoothness and accuracy of the device during movement.

[0060] As Figure 2 And Figure 3 As shown in FIG. 1, in some embodiments, the connecting rods 7, the supporting wheels 6 and the moving wheels 2 are all provided with at least two, two connecting rods 7 are respectively arranged at the two ends of the main support 1, two moving wheels 2 are respectively arranged at the second ends of the two connecting rods 7, and two supporting wheels 6 are respectively arranged at the sides of the two connecting rods 7 close to each other. Two supporting wheels 6 are respectively arranged at the sides of the two connecting rods 7 close to each other, that is, the first supporting wheel 6 is arranged at the side of the first connecting rod 7 close to the second connecting rod 7, and the second supporting wheel 6 is arranged at the side of the second connecting rod 7 close to the first connecting rod 7. In this way, on the one hand, the two moving wheels 2 can be clamped on both sides of the frame 4, that is, the top and bottom thereof, thereby further improving the stability of the cleaning device. On the other hand, the two supporting wheels 6 are respectively arranged at the sides of the connecting rods 7 close to each other, which ensures that the device is uniformly stressed during movement and reduces the risk of damage caused by excessive local pressure.

[0061] In some embodiments, the device further comprises a walking motor 8, which is arranged at the first end of the connecting rod 7. The connecting rod 7 is hollow inside, and the driving end of the walking motor 8 passes through the connecting rod 7 to be connected with the moving wheel 2, so that the walking motor 8 can drive the moving wheel 2 to rotate. Specifically, the side wall of the first end of the connecting rod 7 can be connected with the main support 1, and the walking motor 8 can be fixed outside the first end of the connecting rod 7, with its driving end passing through the connecting rod 7 to be connected with the moving wheel 2, thereby driving the moving wheel 2 to rotate. Alternatively, the top of the first end of the connecting rod 7 can be connected with the main support 1, and the walking motor 8 can be fixed inside the first end of the connecting rod 7, with its driving end passing through the connecting rod 7 to be connected with the moving wheel 2, thereby driving the moving wheel 2 to rotate.

[0062] Specifically, the walking motor 8 can be a direct current motor, a stepping motor or a servo motor, and the appropriate motor type can be selected according to specific requirements. By passing through the connecting rod 7 to be connected with the moving wheel 2, the walking motor 8 can drive the moving wheel 2 to rotate, thereby realizing automatic movement of the device. More specifically, the walking motor 8 can be connected with a controller, and the speed and direction of the motor can be controlled through the controller or programming, thereby realizing precise movement control.

[0063] As Figure 3 shown in FIG. 1, in some embodiments, the cleaning part 3 comprises a cleaning assembly 31 and a driving assembly, the cleaning assembly 31 is slidingly connected on the slide rail 11 of the main support 1, and the driving assembly is connected with the cleaning assembly 31 for driving the cleaning assembly 31 to slide along the slide rail 11. The cleaning assembly 31 is arranged on the second side of the main support 1, and the slide rail 11 extends perpendicular to the moving direction of the moving wheel 2. This design can realize automatic movement of the cleaning assembly 31, thereby improving cleaning efficiency and operation convenience.

[0064] The cleaning assembly 31 is used for actual cleaning work, which can include a brush, a water spraying system, a scraper, etc. The cleaning assembly 31 is slidably connected to the main support 1 through the slide rail 11 or the guide rail, and can reciprocate on the main support 1. The cleaning assembly 31 is arranged on the second side of the main support 1, opposite to the positions of the moving wheels 2 and the supporting wheels 6. The driving assembly is used to drive the cleaning assembly 31 to slide along the main support 1. The driving assembly includes a driving member and a connecting member. The driving member can be selected from an electric motor, a pneumatic motor or a hydraulic motor, and a suitable driving mode is selected according to specific requirements. The connecting member includes a transmission belt, a gear, a lead screw or other transmission mechanisms. The driving member is connected to the cleaning assembly 31 through the transmission belt, the gear, the lead screw or other transmission mechanisms, so as to ensure that the driving assembly can drive the cleaning assembly 31 to slide along the main support 1.

[0065] In particular, the driving member can be connected to the transmission belt, the transmission belt is connected to the cleaning assembly 31, the cleaning assembly 31 is slidably connected to the slide rail 11 of the main support 1, and the transmission belt is driven to rotate by the motor, so as to drive the cleaning assembly 31 to move along the slide rail 11. Walking wheels can also be arranged on the cleaning assembly 31 to cooperate with the slide rail 11, so as to improve the stability of movement.

[0066] As shown in Figure 3 In some embodiments, the cleaning assembly 31 includes a support frame 311, a cleaning roller 313 and a cleaning motor 312. The support frame 311 is slidably connected to the main support 1. The cleaning roller 313 is mounted on the support frame 311, and the extension direction of the cleaning roller 313 is perpendicular to the sliding direction of the support frame 311. The cleaning motor 312 is arranged on the support frame 311 and connected to the cleaning roller 313. The cleaning motor 312 can drive the cleaning roller 313 to rotate.

[0067] The support frame 311 can be made of high-strength materials such as aluminum alloy and stainless steel, to ensure the stability and durability of the structure. The support frame 311 can be slidably connected to the main support 1 through the slide rail 11 or the guide rail. The cleaning roller 313 can generally be made of materials with high wear resistance and strong water absorption, such as sponge, brush or cloth, etc., for cleaning dust and dirt on the surface of the solar cell panel 5. The cleaning motor 312 can be selected from a direct current motor, a stepping motor or a servo motor, and a suitable motor type is selected according to specific requirements. The cleaning motor 312 drives the cleaning roller 313 to rotate, so as to realize efficient cleaning of the surface of the solar cell panel 5.

[0068] Specifically, the cleaning motor 312 can transmit power of the cleaning motor 312 to the cleaning roller 313 through a transmission shaft, or connect the cleaning motor 312 and the cleaning roller 313 through a shaft coupling to ensure the stability of power transmission. More specifically, four protrusions symmetrically arranged on the support frame 311 can be provided, and the rotating shafts of the two cleaning rollers 313 are respectively installed on the four protrusions. The cleaning motor 312 is connected to the rotating shafts of the two cleaning rollers 313 through a chain, so as to drive the two rollers to rotate simultaneously.

[0069] As shown in Figure 5 some embodiments, the cleaning assembly 31 further comprises a water pipe 9 and a plurality of spray heads connected to the water pipe 9. The water pipe 9 is connected to the support frame 311, and the extension direction of the water pipe 9 is the same as that of the cleaning roller 313. The water pipe 9 is made of corrosion-resistant and flexible materials, such as plastic pipe or rubber pipe, etc. The water pipe 9 is used to transport cleaning water to ensure that the spray heads can uniformly spray water. Specifically, the water pipe 9 can be connected to a water tank or other water source. More specifically, the water pipe 9 can be connected to a water pump placed in the water source to supply water to the water pipe 9. More specifically, the water pipe 9 can be fixed on the support frame 311 by using a fixing clamp to ensure the position of the water pipe 9.

[0070] The water pipe 9 can be connected to a water distributor, and the water outlet of the water distributor is connected to the spray head to spray cleaning water. More specifically, the spray head is connected to the water pipe 9 by using a quick connector or a pipe clamp to ensure the stability and detachability of the spray head.

[0073] The water pipe 9 and the air pipe 10 are respectively arranged on both sides of the cleaning roller 313. Specifically, the cleaning roller 313 and the water pipe 9 can be arranged along the movement direction of the support frame 311, so that the water pipe 9 sprays the solar assembly first, then the cleaning roller 313 is cleaned, then the blow head blows the rod after the cleaning roller 313 is cleaned, thereby further improving the cleaning effect.
