[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1 to 4 As shown, the photovoltaic cleaning robot structure described in the present invention includes a frame 1, a roller brush 3 and two parallel rotating shafts 2; a plurality of wheels 4 are fixed to the rotating shaft 2; both ends of the roller brush 3 and both ends of the rotating shaft 2 are rotatably connected to the frame 1; a reduction box 7 with three output ports is provided on the frame 1; one end of the two rotating shafts and one end of the roller brush 3 are respectively connected to the three output ports of the reduction box 7; the input port of the reduction box 7 is connected to a motor 8; side limit members 5 are provided on both sides of the frame 1;

[0026] The motor 8 is fixed on the frame 1, and the motor 8 drives the reduction gearbox 7. The three output ports move synchronously, so that the rotating shaft 2 and the roller brush 3 move synchronously. The wheels 4 move on the frame of the photovoltaic panel. The side limiters 5 position the robot left and right on the photovoltaic panel. Together with the rotating roller brush 3, the surface of the photovoltaic panel is cleaned.

[0027] A bottom stopper 6 is fixed to the frame 1; the bottom stopper 6 includes a fixing seat 605 fixed to the frame 1 and a positioning seat 608 fixed to the fixing seat 605; a slot 60802 is provided on the surface of the positioning seat 608; a roller 607 is rotatably connected to the slot 60802; one end of the positioning seat 608 with the roller 607 extends below the wheel 4;

[0028] The frame 1 is inserted into the photovoltaic panel laterally, the wheel 4 is placed on the upper surface of the photovoltaic panel, and then the roller 607 on the upper surface of the positioning seat 608 is attached to the lower surface of the photovoltaic panel frame. The roller 607 and the wheel 4 are positioned up and down, so that the robot can move in a directional manner, so that the distance between the roller brush 3 and the surface of the photovoltaic panel is not easy to change, thereby ensuring the cleaning quality.

[0029] As a preferred embodiment of the present invention, chamfered surfaces 60801 are provided on the top surface of the positioning seat 608 and on both side surfaces of the positioning seat 608; a guide sleeve 604 is fixed on the fixed seat 605; a screw 601 is slidably connected in the guide sleeve 604; a movable seat 609 is fixed to the bottom end of the screw 601; the positioning seat 608 is fixed on the movable seat 609; an upper limit block 602 and a lower limit block 606 are provided on the screw 601; a spring 603 is sleeved on the rod of the screw 601; the two ends of the spring 603 are respectively pressed on the guide sleeve 604 and the upper limit block 602; the lower limit block 606 is pressed on the bottom surface of the fixed seat 605;

[0030] The spring 603 pushes the upper limit block 602, causing the screw 601 to generate an upward pulling force. The lower limit block 606 is used to limit the highest point of the positioning seat 608, ensuring that the chamfered surface 60801 is directly opposite the bottom surface of the photovoltaic panel before the robot is inserted into the photovoltaic panel. When the robot is inserted into the photovoltaic panel, the chamfered surface 60801 of the positioning seat 608 cooperates with the bottom edge of the photovoltaic panel frame to push the positioning seat 608 downward, so that when the roller 607 is attached to the lower surface of the photovoltaic panel frame, it forms an elastic pressure, ensuring that the roller 607 is always pressed against the photovoltaic panel frame. This provides the robot with a clamping force, making the distance between the roller brush 3 and the photovoltaic panel more stable.

[0031] As a preferred embodiment of the present invention, the upper limit block 602 is a first nut threadedly connected to the screw 601; rotating the first nut can adjust the compression amount of the spring 603, and adjust the pressure of the roller 607 pressed on the photovoltaic panel frame to ensure that the roller 607 and the wheel 4 can firmly clamp the photovoltaic panel frame.

[0032] As a preferred embodiment of the present invention, the lower limit block 606 is a second nut threadedly connected to the screw 601; by rotating the second nut, the relative position of the positioning seat 608 and the fixing seat 605 can be adjusted to ensure that before the robot is put on the photovoltaic panel, the chamfered surface 60801 can be accurately aligned with the bottom edge of the photovoltaic panel frame.

[0033] As a preferred embodiment of the present invention, a guide groove 60101 is provided on the screw 601; the guide groove 60101 extends along the length direction of the screw 601; a guide block 60401 matching the guide groove 60101 is provided on the inner surface of the guide sleeve 604; the guide block 60401 is embedded in the guide groove 60101; the guide block 60401 cooperates with the guide groove 60101, so that the screw 601 will not rotate in the guide sleeve 604, and the screw 601 can only move along the length direction of the guide groove 60101.

[0034] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
