[0025] Hereinafter, a kind of intelligent cleaning device for a photovoltaic power station according to an embodiment of the present specification will be described in detail with reference to the drawings. Figure 1The structural schematic diagram of an intelligent cleaning device for a photovoltaic power station according to an embodiment of this specification is shown. The intelligent cleaning device for a photovoltaic power station according to an embodiment of this specification includes a housing, and a cleaning device, a cleaning driving device, a traveling driving device and traveling devices on both sides of the housing are provided on the housing. The cleaning device includes two brush arms 11 and two brushes 12. The two brush arms 11 are respectively fixed on two opposite outer sides of the housing through connecting shafts 111. Both ends of the brush 12 are respectively connected to the two brush arms 11. The two brushes 12 are respectively located on the other two outer sides of the housing and are connected to the cleaning driving device. The brush arms 11 and the brushes 12 surround the four outer sides of the housing, reducing the interference to the housing and at the same time balancing the center of gravity of the entire device. The brush 12 is not directly connected to the housing and is connected to the housing through the brush arm 11. One brush arm 11 connects one end of the two brushes 12, ensuring the consistency of the cleaning process of the two brushes 12 and making the connection of the whole device more stable.
[0026] In order to enhance the stability of the connection relationship between the brush arm 11 and the housing, both ends of the connecting shaft 111 are respectively located at the centers of the outer sides of the brush arm 11 and the housing to stabilize the center of gravity of the entire device. Support rods 112 are symmetrically provided on both sides of the connecting shaft 111. Both ends of the support rods 112 are respectively connected to the outer sides of the brush arm 11 and the housing, increasing the fixing stability of the brush arm 11. The brush arm 11 is not easy to shake, ensuring the cleaning process of the brush 12. The number of the support rods 112 is determined based on the length of the side of the housing, and is preferably 2-4.
[0027] Specifically, both ends of the brush arm 11 connected to the brush 12 are inclined towards the bottom surface of the housing, reducing the center of gravity of the brush arm 11 and making it closer to the bottom photovoltaic panel to ensure the cleaning process of the photovoltaic panel. The brush arm 11 includes a main arm and short arms connected to both ends of the main arm. The main arm connects the connecting shaft 111 and the support rods 112. The two short arms respectively connect one end of the two brushes 12. The main arm and the short arms are connected in an up-and-down movable manner. The main arm is fixed on the housing, and the short arms connect the brush 12. The main arm and the short arms are connected in an up-and-down movable manner. When the short arms move up and down along the main arm, the height of the brush 12 is adjusted. The position of the short arms after moving can be fixed by fixing parts such as bolts.
[0028] The walking device includes a plurality of walking wheels 21. The walking wheels 21 pass through the machine housing through bearings 22 and are connected to the walking drive device inside the machine housing. The walking wheels 21 are located within the area enclosed by the brush arms 11 and the brush 12. Each of the walking wheels 21 is individually controlled and installed, making the steering and disassembly more convenient compared to a caterpillar-type walking device, having a smaller contact area with the photovoltaic panel, and a lower possibility of causing wear to the photovoltaic panel. The brush arms 11 and the brush 12 surround the walking wheels 21 to protect the walking wheels 21 from being easily interfered by bumps and the like. Preferably, the walking wheels 21 are located outside the machine housing where the brush arms 11 are provided to avoid interference between the movement of the walking wheels 21 and the cleaning process of the brush arms 11. The drive device can be connected to several of the plurality of walking wheels 21. When the walking wheels 21 are located on two opposite outer sides of the machine housing, the number of the walking wheels 21 connected to the drive device on the two outer sides is the same. The number of the walking wheels 21 is not limited to Figure 1 as shown. The drive device is a brushless motor. The cleaning drive device includes two brush motors 42, which are respectively provided on the brush arms 11 at one end of the two brushes 12. The brush motors 42 are brushed motors, having a larger starting torque and simpler speed regulation compared to brushless motors.
[0029] As Figure 2 shown, the middle of the bottom plate of the machine housing is recessed upward, and the walking wheels 21 are installed outside two opposite machine housing side plates 32 of the machine housing. The bottom plate of the machine housing near the walking wheels 21 is concave, reducing the volume of the device while shifting the center of gravity of the device to both sides of the device, increasing the stability during the movement of the device. Moreover, the middle of the bottom plate of the machine housing is raised, reducing the collision between the bottom plate of the machine housing and the photovoltaic panel or obstacles on the photovoltaic panel to a certain extent and protecting the machine housing. The walking drive device includes two walking motors 41, which are respectively located inside the two machine housing side plates 32 where the walking wheels 21 are installed, in the concave part of the bottom plate of the machine housing, reducing the space occupation. The walking motors 41 are connected to the walking wheels 21 near the center position of the machine housing side plates 32. Specifically, the two walking motors 41 are respectively connected to the walking wheels 21 in the middle of the two machine housing side plates 32, and the remaining walking wheels 21 are driven to move.
[0030] In addition, one side of the upper plate 31 of the machine housing is connected to the machine housing side plate 32 through a flip device 5. One end of the movable rod is movably connected to the inner side of the machine housing side plate 32, enabling the movable rod to rotate along this end. The other end of the movable rod is connected to the upper plate 31 of the machine housing. When rotating, the upper plate 31 of the machine housing rotates along the machine housing side plate 32, realizing the opening and closing of the upper plate 31 of the machine housing, facilitating the maintenance and replacement of the internal structure of the machine housing. Figure 3Schematic diagram when the upper plate 31 of the housing is closed. Among them, as Figure 4 shown, the movable rod has a certain angle, reserving a length for the opening and closing of the upper plate 31 of the housing. The angle and number of the movable rods are not limited to those shown in the figure.
[0031] A camera device for monitoring the operating state of the device and the surrounding environment is also provided above the housing, and the camera device is remotely connected to the server. As Figure 3 shown, the camera device includes a first camera 51 and two second cameras 52. The two second cameras 52 are respectively arranged on the front and rear sides in the forward direction of the device, for real-time monitoring of the walking and cleaning processes of the device, so as to make timely adjustments to the walking and cleaning of the device, ensure the cleaning effect and avoid the device deviating from the preset walking route. The first camera 51 is mainly used to observe the surrounding environment of the device, identify the positions of obstacles, charging devices, etc., and is also convenient for adjusting the walking and cleaning processes of the device based on various requirements; the orientations of the first camera 51 and the second camera 52 are adjustable, and the number and installation positions of the first camera 51 and the second camera 52 are not limited to those shown in the figure.
