[0002] Photovoltaic modules are generally installed in the wild where there are few people, and have the characteristics of a large number and a large floor area. After long-term use, the surface of photovoltaic modules is likely to accumulate dust, which affects the power generation efficiency. Therefore, it is necessary to regularly clean the surface of photovoltaic modules. The method of manual cleaning not only has low efficiency, but also has a large workload, and the long-term presence of cleaning workers also increases a large amount of costs. Using a cleaning vehicle controlled by intelligence to automatically clean the photovoltaic modules can improve the cleaning efficiency and save labor costs. However, the existing cleaning vehicles can only clean the surface of photovoltaic modules according to a set program. When there are difficult-to-clean dirt such as bird droppings on the surface of photovoltaic modules, it is difficult to effectively remove these dirt at the normal cleaning speed and frequency. Therefore, it is necessary to identify and separately control the difficult-to-treat dirt on the surface of photovoltaic modules. Summary of the Invention

[0015] Such as Figures 1-3As shown in the figure, an intelligent recognition device for a photovoltaic array cleaning vehicle. The cleaning vehicle includes a vehicle frame, in which a rotating shaft and a rotating motor for driving the rotation of the rotating shaft are installed. A plurality of brushes are installed on the circumferential surface of the rotating shaft. The recognition device includes a CCD industrial recognition camera and an MCU module. The CCD industrial recognition camera is connected to the MCU module. A second battery is installed in the vehicle frame. The MCU module is connected to the second battery for power supply, and the second battery power supply is connected to the rotating motor. The CCD industrial recognition camera is installed on the vehicle frame through a camera mounting bracket. The camera mounting bracket includes a mounting base 40 and a rotating arm 41. The mounting base 40 is fixed in the middle of the vehicle frame. A circular groove 42 is provided on the mounting base 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. One end of the connecting shaft 44 is fixedly connected to the rotating arm 41. The CCD industrial recognition camera is installed at the other end of the rotating arm 41. Two oppositely arranged arc-shaped notches 45 are provided on the rotating plate 43. Two oppositely arranged telescopic channels 46 are provided on the mounting base 40. Positioning spring 47 is respectively inserted into the telescopic channels 46. One end of the positioning spring 47 is located in the circular groove 42 and is connected with a clamping head 48 that matches the arc-shaped notch 45. The other end of the positioning spring 47 is fixed on the mounting base 40. One end of the rotating arm 41 close to the CCD industrial recognition camera is provided with a first inclined guiding surface 51. A first reversing plate 52 is installed at the end of the photovoltaic array 1. A second inclined guiding surface 53 corresponding to the first inclined guiding surface 51 is provided on the first reversing plate 52. A second reversing plate 54 is installed at the head end of the photovoltaic array 1. A third inclined guiding surface 55 corresponding to the first inclined guiding surface 51 is provided on the second reversing plate 54. When the cleaning vehicle 3 moves to the end of the photovoltaic array 1, the rotating arm 41 touches the first reversing plate 52. Under the action of the collision force, through the cooperation of the first inclined guiding surface 51 and the second inclined guiding surface 53, the rotating arm 41 rotates. The positioning spring 47 is distorted and deformed, the clamping head 48 leaves the arc-shaped notch 45, and the positioning spring 47 is compressed and deformed. The rotating arm 41 rotates under the action of inertia. After rotating 180°, the next arc-shaped notch 45 corresponds to the positioning spring 47, the positioning spring 47 recovers, and the clamping head 48 is clamped into the arc-shaped notch 45 to complete the reversing of the rotating arm 41. Thus, the CCD industrial recognition camera can always detect the photovoltaic array 1 to be cleaned in the advancing direction of the cleaning vehicle 3. This design effectively reduces the usage amount of the CCD industrial recognition camera and improves the utilization rate of the CCD industrial recognition camera. At the same time, it reduces the use of electrical equipment for the motor to rotate the rotating arm 41.

[0016] Further, the rotating plate 43 is connected with an inertia flywheel 57 through a gear 56. The two sides of the arc-shaped notch 45 are smoothly transitioned with the circumferential surface of the rotating plate 43. The collision force generated by the collision between the rotating arm 41 and the second reversing plate 54 is used to drive the inertia flywheel 57 to rotate. After the inertia flywheel 57 rotates, the inertia is used to ensure that the rotating arm 41 can rotate 180°.

[0017] Furthermore, a communication system is installed on the sweeper 3. The communication system includes a wireless communication module connected to the MCU module. The wireless communication module is connected to the Internet. The MCU module receives instructions through the wireless communication module and uploads the operation data of the sweeper through the wireless communication module. The operation data of the sweeper 3 and the cleanliness of the photovoltaic array surface can be remotely obtained through the wireless communication module. Thus, the operation frequency of the sweeper 3 can be adjusted and the cleaning time can be reasonably selected.

[0018] Furthermore, a monitoring camera 59 is installed on the sweeper 3, and the monitoring camera 59 is connected to the MCU module.

[0019] Furthermore, the first reversing plate 52 and the second reversing plate 54 are respectively installed at both ends of the photovoltaic array through springs 60, and the length direction of the springs 60 is consistent with the moving direction of the sweeper 3. The springs 60 rebound the impact force to the swing arm 41, further promoting the rotation of the swing arm 41.
