[0037] Referring to Figures 1 to 5The operation robot comprises a vehicle body 100, swing arm walking assemblies 200 and a rolling brush assembly 300. The two swing arm walking assemblies 200 are respectively arranged on the left and right sides of the vehicle body 100. The swing arm walking assembly 200 comprises a swing arm 210, a connecting rod 220 and a walking wheel 230. The connecting rod 220 is fixedly arranged on the vehicle body 100. The swing arm 210 is arranged in a V-shaped structure. The intersection of the V-shaped structure is hingedly connected to one end of the connecting rod 220. The other end of the connecting rod 220 is provided with one walking wheel 230. The two free ends of the V-shaped structure are respectively provided with one walking wheel 230. The three walking wheels 230 are arranged in a straight line. The rolling brush assembly 300 comprises a rolling brush 310 and a connecting structure 320. The connecting structure 320 is hingedly connected to the vehicle body 100. The rolling brush 310 is arranged on the end of the connecting structure 320 away from the vehicle body 100.

[0038] When the operation robot walks, the swing arm 210 is usually located at the front end. When an obstacle is encountered, the swing arm 210 swings. The two walking wheels 230 arranged on the free ends of the swing arm 210 can be self-adapted, thereby enhancing the obstacle-crossing ability of the operation robot and improving the walking stability. The rolling brush 310 is hingedly connected to the vehicle body 100 through the connecting structure 320. When an obstacle is encountered, the obstacle can lift the rolling brush, thereby ensuring that the operation robot can smoothly cross the obstacle. The operation robot has a simple structure and is convenient to install and debug, thereby being beneficial to the productization and large-scale production of the operation robot.

[0039] Preferably, the walking wheel 230 is provided with a guide groove 231 matched with the steel strand. The distance between the two swing arm walking assemblies 200 is the same as the distance between the two steel strands used for laying the photovoltaic module. In actual application, the photovoltaic module is usually supported by two mutually parallel steel strands. The distance between the two swing arm walking assemblies 200 is the same as the distance between the two steel strands used for laying and fixing the photovoltaic module. In this way, the operation robot can smoothly drive into the two steel strands from the photovoltaic module, thereby maintaining the continuity of the walking path and realizing continuous operation.

[0040] Optionally, the connecting structure 320 comprises a rotary connecting rod 321 and an elastic telescopic member 322. The rotary connecting rod 321 is hingedly connected to the vehicle body 100. One end of the rotary connecting rod 321 is connected to the rolling brush 310. The other end of the rotary connecting rod 321 is connected to the first end of the elastic telescopic member 322. The second end of the elastic telescopic member 322 is fixedly connected to the vehicle body 100. When an obstacle is encountered, the obstacle can lift the rolling brush. The elastic telescopic member 322 is retracted. The operation robot can smoothly cross the obstacle. In this embodiment, the elastic telescopic member 322 is a gas spring. The gas spring can play the roles of support, buffering, braking and height adjustment. The speed of the gas spring is relatively slow during operation, thereby being easy to control.

[0041] Specifically, referring to Figure 3The rotary connecting rod 321 is connected with the roller brush 310 through a cover plate 330. The cover plate 330 is in a strip shape, and the cover plate 330 is provided with a receiving groove for receiving part of the roller brush 310. The two ends of the roller brush 310 are respectively rotatably connected to the two side walls of the receiving groove. The cover plate 330 can protect the roller brush 310. In addition, the two ends of the roller brush 310 are rotatably connected to the receiving groove, which facilitates disassembly and assembly.

[0042] In this embodiment, the roller brush 310 includes a roller and a plurality of bristles. The plurality of bristles are uniformly distributed or spirally distributed along the circumference of the roller. The two ends of the roller are rotatably connected to the two side walls of the receiving groove. When the roller rotates, the bristles rotate with the roller. The bristles contact the surface of the photovoltaic module to clean the photovoltaic module. The number and density of the bristles can be set as required.

[0043] As a preferred embodiment, the roller brush assembly 300 is provided with two groups. The two groups of roller brush assemblies 300 are respectively installed on the front and rear sides of the vehicle body 100. This arrangement can effectively improve the cleaning efficiency of the roller brush assembly 300.

[0044] Optionally, referring to Figure 4 The vehicle body 100 includes a vehicle main body 110 and a support plate 120 installed on the vehicle main body 110. The support plate 120 includes a first guide plate 121 and a second guide plate 122 arranged at right angles. The first guide plate 121 is connected with the vehicle main body 110. The rotary connecting rod 321 is hingedly connected to one end of the second guide plate 122 away from the first guide plate 121. The elastic extension member 322 is connected with the second guide plate 122. The support plate 120 facilitates the connection between the connecting structure 320 and the vehicle main body 110. The first guide plate 121 provides sufficient space between the rotary connecting rod 321 and the vehicle main body 110. When the roller brush cylinder is lifted, the rotary connecting rod 321 can move fully.

[0045] Optionally, a control box is arranged in the vehicle main body 110. The control box is provided with a control mechanism for controlling the rotation of the walking wheel 230. The control mechanism includes an electric power source and a control unit electrically connected. The electric power source provides electric energy for the control unit. The control unit is used to control the rotation of the walking wheel 230.

[0046] The operation and maintenance robot further includes a support frame 400 arranged above the vehicle body 100. The two ends of the support frame 400 are respectively provided with a rotating wheel 500 for rectification. When the operation and maintenance robot walks on the photovoltaic module, the rotating wheels 500 on both sides rotate along the side surface of the corresponding photovoltaic module, which corrects the walking direction and prevents the robot from tilting, thereby ensuring that the operation and maintenance robot walks along the photovoltaic module.
