Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and specifically to a self-cleaning device for a photovoltaic new energy power station. Background Art

[0002] A photovoltaic new energy power station is a facility that uses solar energy for power generation. It uses special materials such as crystalline silicon panels and other electronic components to form a power generation system, which is connected to the power grid and transmits electricity to the power grid. Therefore, the cleaning and maintenance of a photovoltaic new energy power station are crucial for ensuring its power generation efficiency.

[0003] In the prior art, many photovoltaic power stations adopt the method of equipping each photovoltaic panel group with a separate cleaning device. Although it can perform targeted automated cleaning for a single photovoltaic panel group to a certain extent, due to the large number of cleaning devices, the equipment maintenance cost is high, and when facing a large area of photovoltaic panel groups, the overall cleaning efficiency is low.

[0004] In addition, although the existing self-cleaning device can perform integral cleaning on the entire photovoltaic panel group, the sewage generated during a single cleaning process is not effectively managed and guided. The untreated sewage may flow to the area that has been cleaned, causing secondary pollution and reducing the cleaning effect.

[0005] Therefore, it is necessary to provide a self-cleaning device for a photovoltaic new energy power station to solve the technical problems raised in the above background art. Summary of the Invention

Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0038] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features; in the description of the present invention, unless otherwise stated, "a plurality of" means two or more.

[0039] Please refer to Figures 1-9 , an embodiment of the present invention provides a self-cleaning device for a photovoltaic new energy power station, which includes:

[0040] The chassis 1 is fixedly arranged on the ground, and a water storage system is arranged on the ground;

[0041] The photovoltaic panel group 2 is uniformly and fixedly arranged on the chassis 1; and

[0042] The cleaning device 3 is arranged on the upper and lower sides of the photovoltaic panel group 2 so as to be horizontally and laterally movable, and the cleaning device 3 is communicated with the water storage system through a pump body.

[0043] Based on the above technical solution, at the beginning, the cleaning device 3 is first placed on the photovoltaic panel group 2, and then the cleaning device 3 and the pump body are started to longitudinally clean the surface of the photovoltaic panel group 2. The cleaned area is the cleaned area, and the area to be cleaned is the uncleaned area. And the cleaning device 3 performs at least two reciprocating cleanings on the cleaned area, and then controls the cleaning device 3 to move along the upper and lower edges of the photovoltaic panel group 2 to clean the uncleaned area, and repeats the above steps to perform an overall cleaning on the surface of the photovoltaic panel group 2.

[0044] On the basis of the above technical solution, the cleaning device 3 arranged can longitudinally clean the surface of the photovoltaic panel group 2. At the same time, the cleaning device 3 can horizontally and laterally move along the upper and lower ends of the photovoltaic panel group 2 to ensure covering the surface of the photovoltaic panel group 2, and the cleaning work of large-area photovoltaic panels can be quickly completed through unified control, reducing the maintenance time and labor cost, and greatly reducing the cleaning cycle and time.

[0045] In a possible implementation manner, the cleaning device 3 includes:

[0046] The frame 311 is arranged in a rectangular structure. A stop buffer area 314 is fixedly arranged at the upper end of the frame 311. A power storage system is fixedly arranged at the lower end of the stop buffer area 314. And lateral wheels 315 are rotatably arranged at positions on the frame 311 corresponding to the uppermost and lowermost edges of the photovoltaic panel group 2. A driving motor for driving the lateral wheels 315 to rotate is arranged on the frame 311. Longitudinal wheels 316 are rotatably arranged at positions on the frame 311 corresponding to the upper and lower ends of the upper surface of the photovoltaic panel group 2;

[0047] Two side frames 312 are configured and symmetrically fixed on the lateral sides of the frame 311. Blocking units 313 are arranged in the side frames 312; and

[0048] Two rotating wheels 317 are configured and are rotatably arranged on the frame 311 between the two side frames 312. A rotating belt 318 is rotatably arranged on the rotating wheels 317. A cleaning unit 319 is fixedly arranged on one side of the rotating belt 318. The other side of the rotating belt 318 passes through the cleaning unit 319.

[0049] Through the above technical solution, by means of the provided cleaning device 3, the transverse wheels 315 are configured to horizontally move horizontally along the upper and lower ends of the photovoltaic panel group 2. The longitudinal wheels 316 can support and assist in the movement of the frame 311 during the operation of the cleaning device 3. Meanwhile, during the movement of the cleaning unit 319, the conveyor belt 318 is driven to rotate along the rotating wheel 317.

[0050] In a possible implementation manner, a driving mechanism is fixedly arranged inside the cleaning unit 319, and the driving mechanism is electrically connected to the power storage system. A plurality of nozzles are fixedly arranged inside the cleaning unit 319. The nozzles are all communicated with the output end of the pump body. A roller brush is rotatably arranged inside the driving mechanism, and the output end of the driving mechanism is in transmission connection with the roller brush.

[0051] Adopting the above technical solution, after the driving mechanism is started, the roller brush rotates, enabling the cleaning unit 319 to generate a driving force. Under the action of the conveyor belt 318, the cleaning unit 319 can longitudinally move along the surface of the photovoltaic panel group 2.

[0052] In a possible implementation manner, rollers 3191 are rotatably arranged on both lateral sides of the cleaning unit 319, which can reduce the movement resistance of the cleaning unit 319.

[0053] In a possible implementation manner, the side frame 312 includes a base frame 3121 fixedly arranged at the upper end of the frame 311. Upper grooves 3122 and lower grooves 3123 are respectively opened on the base frame 3121 from top to bottom. The groove width of the upper groove 3122 is greater than that of the lower groove 3123. Through grooves 3124 are penetrated through both lateral sides of the side frame 312.

[0054] In a possible implementation manner, the rollers 3191 are movably arranged in the upper grooves 3122, and the projection of the rollers 3191 along the traveling direction of the base frame 3121 covers the lower grooves 3123, so that the rollers 3191 can always press down the blocking unit 313 during the movement.

[0055] In a possible implementation, the blocking unit 313 includes a first hinge plate 3131 rotatably disposed on one side of the base frame 3121 between the lower troughs 3123. The other side of the first hinge plate 3131 is hinged with a second hinge plate 3132. Hinge shafts 3133 are hinged at the central positions of the first hinge plate 3131 and the second hinge plate 3132. The lower ends of the hinge shafts 3133 are hinged with blocking bars 3134, and the blocking bars 3134 are vertically liftably disposed inside the lower troughs 3123. That is, when the first hinge plate 3131 and the second hinge plate 3132 are pressed down, the hinge shafts 3133 drive the upper ends of the blocking bars 3134 to descend along the lower troughs 3123; when the first hinge plate 3131 and the second hinge plate 3132 rise, the hinge shafts 3133 drive the upper ends of the blocking bars 3134 to rise along the lower troughs 3123.

[0056] In a possible implementation, both sides of the end of the second hinge plate 3132 away from the first hinge plate 3131 are rotatably disposed on sliding blocks 3135. The sliding blocks 3135 are both limitedly movable in the through grooves 3124, and the ends of the sliding blocks 3135 away from the first hinge plate 3131 are fixedly disposed with the through grooves 3124 through support springs 3136.

[0057] Through the above technical solution, after the cleaning unit 319 is placed on the photovoltaic panel group 2, the driving mechanism and the pump body are started. During the rotation of the roller brush, the cleaning unit 319 moves downward along the surface of the photovoltaic panel group 2, and at the same time the nozzle sprays water. During the movement of the roller 3191, the second hinge plate 3132 and the first hinge plate 3131 are pressed down, the sliding block 3135 moves upward, the support spring 3136 is compressed, and the blocking bar 3134 descends along the lower trough 3123 and contacts the surface of the photovoltaic panel group 2. When the cleaning unit 319 moves to the lowermost end, the support spring 3136 restores its deformation, the sliding block 3135 moves downward, and the second hinge plate 3132 and the first hinge plate 3131 return to the angular hinge state; then the driving mechanism is started in reverse, the roller brush rotates in reverse, the cleaning unit 319 moves upward along the surface of the photovoltaic panel group 2, and at the same time the nozzle sprays water. During the movement of the roller 3191, the first hinge plate 3131 and the second hinge plate 3132 are pressed down, the sliding block 3135 moves upward, the support spring 3136 is compressed, and the blocking bar 3134 descends along the lower trough 3123 and contacts the surface of the photovoltaic panel group 2. When the cleaning unit 319 moves to the uppermost end, the support spring 3136 restores its deformation, the sliding block 3135 moves downward, and the second hinge plate 3132 and the first hinge plate 3131 return to the angular hinge state.

[0058] On the basis of the above technical solution, during the process of the cleaning unit 319 moving along the side frame 312, the first hinge plate 3131 and the second hinge plate 3132 drive the baffle strip 3134 to descend and fit onto the surface of the photovoltaic panel group 2. The nozzle of the cleaning unit 319 sprays water while the roller brush rotates to clean the surface of the photovoltaic panel group 2. The baffle strip 3134 can effectively divert the sewage and prevent the sewage from flowing to the cleaned area, ensuring that each area can maintain the best cleaning state and avoiding re-pollution caused by the backflow of sewage.

[0059] In a possible implementation manner, the baffle strip 3134 includes a clamping seat 31341 whose upper end is hinged to the hinge shaft 3133, and a baffle 31342 is fixedly arranged at the lower end of the clamping seat 31341.

[0060] In a possible implementation manner, the baffle 31342 is made of a plastic soft waterproof material to prevent extrusion damage to the surface of the photovoltaic panel group 2.

[0061] During specific implementation, in the initial state, the cleaning unit 319 is located at the shutdown buffer area 314. After the cleaning unit 319 is placed on the photovoltaic panel group 2, the driving mechanism and the pump body are started. During the rotation of the roller brush, the cleaning unit 319 moves downward along the surface of the photovoltaic panel group 2, and simultaneously the nozzle sprays water. During the movement of the roller 3191, the second hinge plate 3132 and the first hinge plate 3131 are pressed down, the sliding block 3135 moves upward, the support spring 3136 is compressed, and the baffle strip 3134 descends along the lower groove body 3123 and contacts the surface of the photovoltaic panel group 2. When the cleaning unit 319 moves to the lowermost end, the support spring 3136 resumes its deformation, the sliding block 3135 moves downward, and the second hinge plate 3132 and the first hinge plate 3131 resume their angular hinge states; then the driving mechanism is started in reverse, the roller brush rotates in reverse, the cleaning unit 319 moves upward along the surface of the photovoltaic panel group 2, and simultaneously the nozzle sprays water. During the movement of the roller 3191, the first hinge plate 3131 and the second hinge plate 3132 are pressed down, the sliding block 3135 moves upward, the support spring 3136 is compressed, and the baffle strip 3134 descends along the lower groove body 3123 and contacts the surface of the photovoltaic panel group 2. When the cleaning unit 319 moves to the uppermost end, the support spring 3136 resumes its deformation, the sliding block 3135 moves downward, and the second hinge plate 3132 and the first hinge plate 3131 resume their angular hinge states. The cleaning unit 319 then moves downward along the surface of the photovoltaic panel group 2 to the bottom end at least once and repeats the above steps. When the cleaning unit 319 moves to the lowermost end for the last time, the pump body is turned off, the driving mechanism is started in reverse, the roller brush rotates in reverse, and the cleaning unit 319 moves upward along the surface of the photovoltaic panel group 2 until it reaches the highest position;

[0062] Then start the drive motor, and the entire cleaning device 3 moves horizontally along the photovoltaic panel group 2, and the frame 311 located at the rear side of the traveling direction is always located within the cleaning area, and repeat the above steps until the entire surface of the photovoltaic panel group 2 is cleaned.

[0063] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
