[0024] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] like Figure 1-8As shown, an intelligent photovoltaic module cleaning machine is shown, wherein the photovoltaic modules are divided into several rows, and each row of photovoltaic modules is composed of several interconnected photovoltaic modules 1 arranged in sequence. The cleaning machine includes a transfer track 2 and a cleaning vehicle 3. The transfer track 2 is provided with a transfer frame 4, and the transfer frame 4 is driven by a transfer motor to move on the transfer track 2. The transfer frame 4 is equipped with a first battery 5, and the first battery 5 supplies power to the transfer motor. The head end of each row of photovoltaic modules is close to one side of the transfer track 2. The transfer frame 4 is equipped with a transition plate 6, and the transition plate 6 has a The cleaning vehicle 3 includes a rotating shaft 7 and a rotating motor that drives the rotating shaft 7. The rotating shaft 7 is rotatably mounted on a frame 8, with pulleys 9 mounted at each end. The upper and lower ends of the photovoltaic module 1 respectively form tracks for the pulleys 9. The upper and lower ends of the transition plate 6 respectively form transition tracks for the pulleys. Some of the pulleys 9 are driven by the mobile motor. A second battery is installed within the frame 8, powering both the rotating and transition motors. Several brushes 10 are mounted on the circumference of the rotating shaft 7. The transfer frame 4 moves along the transfer track 2 to a row of photovoltaic modules, then stops. The transition plate 6 then docks with the leading ends of the row. The cleaning vehicle 3 is activated and transferred to the photovoltaic modules via the transition plate 6. The rotating shaft 7 then rotates, and as the cleaning vehicle 3 moves, the brushes 10 on the rotating shaft 7 clean the photovoltaic modules. After sweeper 3 reaches the end of a row of PV panels, the motor reverses, and sweeper 3 returns, with brush 10 performing a second pass over the panels. Sweeper 3 then returns to transition plate 6. Transfer rack 4 moves to the next row of PV panels. Repeat these steps to clean multiple rows of PV panels.

[0026] Furthermore, a first photovoltaic panel 11 is mounted on the transfer rack 4 to charge the first battery 5, and a second photovoltaic panel 12 is mounted on the sweeper 3 to charge the second battery. The first photovoltaic panel 11 and the second photovoltaic panel 12 provide automatic supplemental power to the transfer rack 4 and the sweeper 3, respectively.

[0027] Furthermore, the brushes 10 are arranged in a spiral pattern on the circumference of the rotating shaft 7. This allows dust and other debris to be swept downwards during the rotation of the rotating shaft 7 using the principle of screw conveyance, preventing dust from being swept into other areas of the photovoltaic module and improving cleaning efficiency. The rotating shaft 7 has spirally arranged threaded holes 13, and the ends of the brushes 10 are fixedly connected to threaded rods 14 that mate with the threaded holes 13. This allows for easy, individual replacement of the brushes 10, reducing maintenance costs. The frame 8 is provided with a cover plate 15 that covers the rotating shaft 7. Several comb teeth 16 are fixed to the surface of the cover plate 15 near the rotating shaft 7. During the rotation of the rotating shaft 7, the comb teeth 16 act on the brush 10, combing the feathers and other debris that the brush 10 removes from the photovoltaic module 1 and preventing them from becoming entangled in the debris comb of the brush 10. This ensures the cleaning efficiency of the brush 10, prevents excessive entanglement of feathers and other debris from affecting the cleaning effect, and prevents hard objects such as the rachis and quills of feathers from damaging the surface of the photovoltaic module. The lower ends of the comb teeth 16 are bent upward to form hooks 17, with the hooks 17 of adjacent comb teeth 16 facing in different directions. This improves the comb teeth 16's ability to collect feathers and other debris. One side of the cover 15 is hinged to the vehicle frame 8 via a hinge 18, and the second photovoltaic panel 12 is secured to the outside of the cover 15. By flipping open the cover 15, debris collected on the comb teeth 16 can be easily cleaned.

[0028] Furthermore, a water storage box 19 is located below each row of photovoltaic panels 1. The lower ends of the photovoltaic panels 1 are positioned above the water storage boxes 19. A water nozzle 20 is located at the upper end of the vehicle frame 8. The nozzle 20 is connected to a micro-water pump 26, which is mounted within the vehicle frame 8. The water inlet of the micro-water pump 26 is connected to a hose 21, which naturally droops from the lower end of the vehicle frame 8 and extends into the water storage box 19. After the cleaning vehicle 3 moves over the photovoltaic panels 1, the hose 21 naturally droops into the water storage box 19. The micro-water pump 26 draws water from the water storage box 19 and sprays it onto the photovoltaic panels 1 using the nozzle 20, improving cleaning efficiency. The water storage box 19 contains a certain amount of water. Water from natural rainfall and cleaning uses flows down the photovoltaic panels 1 and is collected in the water storage box 19, reducing the frequency of refilling the water storage box 19.

[0029] Furthermore, the water storage box 19 is provided with an inclined cover plate 22, and an opening 23 is formed between the lower edge of the inclined cover plate 22 and the inner wall of the water storage box 19. A shielding plate 24 is provided above the opening 23, and the shielding plate 24 is fixed to the water storage box 19. The design of the inclined cover plate 22 and the shielding plate 24 can reduce the evaporation of water and also reduce the amount of debris that falls into the water storage box 19. This prevents animals from drinking water from the water storage box 19. The lower end of the hose 21 is connected to a spherical counterweight 25. The counterweight 25 rolls on the inclined inclined cover plate 22, which can facilitate the end of the hose 21 to pass through the opening 23 and extend into the water storage box 19. The frame 8 is equipped with an electric push rod 27, powered by a second battery. It is connected to a push plate 28, which is provided with a movable hole 29. The hose 21 is divided into a fixed portion 30 and a movable portion 31. The fixed portion 30 is fixed to the upper and lower ends of the frame 9, respectively, while the movable portion 31 passes through the movable hole 29. When the sweeper 3 moves to the head end of the photovoltaic array 1, the electric push rod 27 retracts, causing the lower end of the hose 21 to descend and gradually extend into the water storage box 19. When the sweeper 3 completes cleaning and returns to the head end of the photovoltaic array 1, the electric push rod 27 extends, causing the lower end of the hose 21 to rise and disengage from the water storage box 19, without hindering the movement of the sweeper 3. The water storage box 9 is equipped with a heater 32, each of which is connected to a third battery, which is charged by the corresponding photovoltaic array 1. This prevents the water in the water storage box 9 from freezing. The water nozzle 20 is mounted on a water outlet box 33, which is fixed to the upper end of the frame 8. The upper end of the fixed portion 30 is connected to the water outlet box 33. An electric heater 34 is installed in the water outlet box 33, which is powered by a second battery. This allows the water temperature to be controlled. When ice forms on the photovoltaic modules 1, warm water and a brush 10 can be used to remove the ice, ensuring the photovoltaic modules' power generation efficiency. A shielding film is connected to the shielding plate 24, which further reduces water evaporation. A filter plate 35 is mounted on the lower end of the frame 8, with a deflector 36 located above the filter plate 35. The deflector 36 guides the water sprayed from the water nozzle 20 during the cleaning process, improving the collection efficiency of the water storage box 19 and reducing water waste. The filter plate 35 intercepts debris in the cleaned wastewater. A cleaning brush 37 is located at the end of each row of photovoltaic modules 1. After the sweeper 3 reaches the end of each row of photovoltaic modules 1 , the filter plate 35 passes through the cleaning brush 37 , and the cleaning brush 37 sweeps off the debris trapped on the filter plate 35 .

[0030] Furthermore, the frame 8 is equipped with an identification device for identifying foreign objects on the photovoltaic modules. The identification device includes a CCD industrial identification camera 38 and an MCU module. The CCD industrial identification camera 38 is connected to the MCU module, which is then powered by a second battery. The mobile motor, rotary motor, and micro water pump 26 are each connected to the MCU module. The CCD industrial identification camera 38 identifies whether there is bird droppings or ice flakes on the photovoltaic modules. The MCU module controls the forward and reverse rotation of the mobile motor, thereby controlling the sweeper 3 to sweep back and forth several times, effectively removing bird droppings and other items from the photovoltaic modules and ensuring that the photovoltaic modules can generate electricity normally.

[0031] Furthermore, the MCU module is connected to a GPS positioning module and a wireless communication module, and the CCD industrial recognition camera 38 is installed on the vehicle frame 8 through a camera mounting bracket 39. The camera mounting bracket 39 includes a mounting seat 40 and a rotating arm 41. The mounting seat 40 is fixed to the middle of the vehicle frame 8. A circular groove 42 is provided on the mounting seat 40. A rotating plate 43 is rotatably installed in the circular groove 42. A connecting shaft 44 is fixedly connected to the rotating plate 43. The connecting shaft 44 is fixedly connected to one end of the rotating arm 41. The CCD industrial recognition camera 38 is installed at the other end of the rotating arm 41. Two arc-shaped notches 45 are arranged opposite to each other on the rotating plate 43. The mounting seat 40 is provided with two telescopic notches 45 arranged opposite to each other. Channel 46 and telescopic channel 46 each have a retaining spring 47 movably inserted therein. One end of the retaining spring 47 is located in the circular groove 42 and connected to a retaining head 48 that matches the arc-shaped notch 45. The other end of the retaining spring 47 is fixed to the mounting base 40. A first inclined guide surface 51 is provided on the end of the rotating arm 41 near the CCD industrial identification camera 38. A first reversing plate 52 is mounted at the end of each row of photovoltaic modules 1. The first reversing plate 52 is provided with a second inclined guide surface 53 corresponding to the first inclined guide surface 51. A second reversing plate 54 is mounted on the transition plate 6. The second reversing plate 54 is provided with a third inclined guide surface 55 corresponding to the first inclined guide surface 51. When the sweeper 3 moves to the end of each row of photovoltaic modules 1, the rotating arm 41 collides with the first reversing plate 52. Under the action of the collision force, the rotating arm 41 rotates through the cooperation between the first inclined guide surface 51 and the second inclined guide surface 53. The locking spring 47 twists and deforms, and the retaining head 48 leaves the arc-shaped notch 45, causing the locking spring 47 to compress and deform. The rotating arm 41 rotates under the action of inertia. After rotating 180°, the next arc-shaped notch 45 aligns with the locking spring 47. The locking spring 47 recovers, and the retaining head 48 snaps into the arc-shaped notch 45, completing the reversal of the rotating arm 41. This allows the CCD industrial recognition camera 38 to always detect the photovoltaic modules 1 that need to be cleaned in the direction of the sweeper 3's advance. This design effectively reduces the usage of the CCD industrial recognition camera 38 and improves its utilization rate. It also reduces the use of electrical equipment used by the motor to rotate the rotating arm 41.

[0032] Furthermore, the rotating plate 43 is connected to an inertia flywheel 57 via a gear 56. A smooth transition is formed between the two sides of the arc-shaped notch 45 and the circumferential surface of the rotating plate 43. The inertia flywheel 57 is driven to rotate by the collision force generated by the rotating arm 41 and the second reversing plate 54. After the inertia flywheel 57 rotates, its inertia ensures that the rotating arm 41 can rotate 180 degrees.

[0033] Furthermore, the sweeper 3 is equipped with a communication system comprising a wireless communication module connected to the MCU module. The wireless communication module is connected to the internet. The MCU module receives instructions via the wireless communication module and uploads the sweeper's operating data via the wireless communication module. The wireless communication module allows for remote access to sweeper 3 operating data and the cleanliness of the photovoltaic panel surface. This allows for adjustment of the sweeper 3's operating frequency and optimal selection of cleaning times.

[0034] Furthermore, a monitoring camera 59 is installed on the sweeper 3, and the monitoring camera 59 is connected to the MCU module.

[0035] It is worth mentioning that the technical features such as the CCD industrial identification camera 38 and the surveillance camera 59 involved in the patent application of the present invention should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional means in the field and should not be regarded as the inventive point of the patent of the present invention. The patent of the present invention will not be further elaborated.

[0036] The above describes in detail the preferred specific embodiments of the present invention. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of existing technologies should be within the scope of protection determined by the claims.
