[0002] Solar energy is an inexhaustible, clean, pollution-free and renewable green energy. The use of solar energy to generate electricity has the advantages of cleanliness, high safety, widespread and sufficient energy, long life and maintenance-free. Photovoltaic energy is considered to be the most important new energy in the 21st century and plays a key role. Photovoltaic panel components are a kind of power generation device that will generate direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials. Due to long-term exposure to the outdoors, there will be a large amount of dust, bird droppings and other attachments on the photovoltaic panels that provide electricity. The more attachments there are, the more light will be blocked, affecting the absorption of light by the photovoltaic panels, thereby affecting the efficiency of photovoltaic power generation. Therefore, the photovoltaic panels need to be cleaned.

[0003] In order to better absorb light, most existing photovoltaic panels are installed on higher brackets at an angle, which makes cleaning more complicated. Usually, the surface of the photovoltaic panels is manually rinsed with a water pipe. However, a single rinse cannot clean bird droppings and scabby powder blocks. Therefore, workers are required to climb above the photovoltaic panels to cooperate in cleaning the bird droppings and scabby powder blocks. This not only requires a large amount of manual labor, but also easily creates safety hazards. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a photovoltaic panel cleaning device for a photovoltaic power station, comprising a mounting plate 1, the back of the mounting plate 1 is fixedly connected with supporting legs 2 distributed in a rectangular array, the front of the mounting plate 1 is fixedly installed with photovoltaic panel bodies 3 distributed in a rectangular array, the front of the mounting plate 1 is fixedly connected with mounting blocks 4 distributed symmetrically, a mounting groove 5 is opened on one side surface of the mounting block 4, a reciprocating screw 6 is installed on the inner bottom wall of the mounting groove 5 through a bearing, and one end of the reciprocating screw 6 penetrates and extends to the upper surface of the mounting block 4;

[0021] The outer surface of the reciprocating screw rod 6 is provided with an automatic cleaning device, and the automatic cleaning device comprises a synchronous wheel 7 , and the inner wall of the synchronous wheel 7 is fixedly sleeved with the outer surface of the reciprocating screw rod 6 .

[0022] Furthermore, the outer surfaces of the two synchronous wheels 7 are both transmission-connected with a synchronous belt 71, the front side of one of the mounting blocks 4 is fixedly connected with a rack 72, and the front side of the mounting plate 1 is fixedly mounted with a servo motor 73. The synchronous wheels 7 and the synchronous belt 71 are used in conjunction with each other to achieve synchronous rotation of the two reciprocating screws 6.

[0023] Furthermore, the output shaft of the servo motor 73 is fixedly connected to one end of one of the reciprocating screw rods 6 through a coupling, and a threaded block 74 is threadedly sleeved on the outer surface of the reciprocating screw rod 6, and the outer surface of the threaded block 74 is movably sleeved on the inner wall of the mounting groove 5. The servo motor 73 drives the reciprocating screw rod 6 to rotate clockwise and counterclockwise, and the rotation of the reciprocating screw rod 6 drives the threaded block 74 to move.

[0024] Furthermore, the opposing surfaces of the two threaded blocks 74 are fixedly connected with a movable plate 75, and the front side of the movable plate 75 is provided with mounting holes 76 distributed in a linear array, and the inner wall of the mounting hole 76 is installed with a pressure sleeve 77 through a bearing. The movement of the threaded block 74 drives the pressure sleeve 77 to move through the movable plate 75, and the pressure sleeve 77 cooperates with the bearing through the mounting hole 76 to play a role of positioning and rotation.

[0025] Furthermore, a transmission gear 78 is fixedly sleeved on the outer surface of the pressure sleeve 77, and the tooth surfaces of two adjacent transmission gears 78 mesh with each other. The tooth surface of one of the transmission gears 78 meshes with the tooth surface of the rack 72. The inner wall of the pressure sleeve 77 is provided with symmetrically distributed limiting grooves 79. The movement of the pressure sleeve 77 causes one of the transmission gears 78 to rotate through the cooperation of the rack 72, and the mutual meshing of the transmission gears 78 causes multiple pressure sleeves 77 to rotate.

[0026] Furthermore, the inner wall of the limiting groove 79 is slidably connected to the limiting slider 710, and the opposing surfaces of the two limiting sliders 710 are fixedly connected with a pressure rod 711. The outer surface of the pressure rod 711 is movably socketed with the inner wall of the pressure sleeve 77, and one end of the pressure rod 711 is fixedly connected with a cleaning disk 712. The limiting groove 79 and the limiting slider 710 are used in conjunction to enable the pressure rod 711 to rotate synchronously when the pressure sleeve 77 rotates while moving up and down.

[0027] Furthermore, the back side of the cleaning plate 712 contacts the front side of the photovoltaic panel body 3, the other end of the pressure rod 711 is fixedly connected to a pressure spring 713, one end of the pressure spring 713 is fixedly connected to the inner top wall of the pressure sleeve 77, and the cleaning plate 712 cooperates with the elastic force of the pressure spring 713 to increase the cleaning force on the photovoltaic panel body 3. The back side of the cleaning plate 712 is provided with elastic bristles distributed in a circular array, so as to facilitate the cleaning of crusted powder and bird droppings.

[0028] Through the automatic cleaning device, the scabby powder and bird droppings on the photovoltaic panel body 3 can be cleaned, thereby avoiding manual climbing and cleaning. This not only reduces manual labor and eliminates safety hazards during climbing, but also improves the cleaning efficiency of the photovoltaic panel body 3.

[0029] Working principle: Step 1, when washing the photovoltaic panel body 3, start the servo motor 73 to drive the reciprocating screw 6 to rotate clockwise, and the two reciprocating screws 6 are rotated synchronously through the cooperation of the synchronous belt 71 and the synchronous wheel 7. The rotation of the reciprocating screw 6 drives the threaded block 74 to move through the limit of the installation groove 5, and the movement of the threaded block 74 drives the moving plate 75 to move. The movement of the moving plate 75 causes one of the transmission gears 78 meshing with the rack 72 to rotate, and the transmission gears 78 mesh with each other to rotate multiple pressure sleeves 77;

[0030] In step two, the rotation of the pressure sleeve 77 drives the pressure rod 711 to rotate through the cooperation of the limit slide groove 79 and the limit slider 710. The rotation of the pressure rod 711 cleans the surface of the photovoltaic panel body 3 through the cleaning disk 712. The extrusion elastic force generated by the pressure spring 713 on the pressure rod 711 makes it easier to clean the crusted powder and bird droppings when the cleaning disk 712 rotates, and the water flow sprayed from the water pipe rinses the cleaned debris. When the servo motor 73 drives the reciprocating screw 6 to rotate clockwise for a specified number of turns, it continues to drive the reciprocating screw 6 to rotate counterclockwise for a specified number of turns, thereby driving the cleaning disk 712 to reciprocate and clean the surface of the photovoltaic panel body 3.
