Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a cleaning device for photovoltaic panels. Background Technology

[0002] Photovoltaic panels, also known as solar panels or solar panels, are devices that can directly convert sunlight into electrical energy. They typically consist of multiple photovoltaic cells made of semiconductor materials (usually silicon). When sunlight shines on a photovoltaic cell, electrons in the semiconductor material are excited, generating an electric current.

[0003] After a period of use, photovoltaic panels accumulate a large amount of dust and other impurities on their surface. The presence of these impurities can affect the absorption and utilization of light energy by the photovoltaic panels, thus requiring a cleaning device for cleaning. For example, Chinese Patent Announcement No. "CN218925604U" discloses a photovoltaic panel cleaning vehicle, which includes a water truck, a support frame, and brush rollers. A rotating disk is installed at the top front end of the water tank of the water truck. The top of the rotating disk is movably connected to the end of the support frame via a rotating shaft. A hydraulic cylinder is installed on the outer edge of the rotating disk and the lower end of the support frame. The support frame is equipped with a left-right angle adjustment mechanism, which is connected to a tilt angle adjustment mechanism. The left-right angle adjustment mechanism and the tilt angle adjustment mechanism can control the angle of the brush rollers.

[0004] Most existing photovoltaic panel cleaning devices use roller brushes in conjunction with water spraying for cleaning. The roller brushes will wear out after prolonged use and need to be replaced. Existing devices use an integral roller brush, which is inconvenient to replace. In addition, the nozzles are prone to clogging when the cleaning device is used in the external environment for a long time. Utility Model Content

[0005] The purpose of this invention is to solve the problems of inconvenient replacement of the roller brush and easy clogging of the nozzle in the existing cleaning devices, and to propose a cleaning device for photovoltaic panels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a cleaning device for photovoltaic panels, including a connecting plate connected to a water truck, characterized in that: two mounting brackets are fixedly connected to the lower end of the connecting plate, a rotating shaft is rotatably connected to each of the two mounting brackets, a roller is fixedly connected between the two rotating shafts, a cleaning mechanism is provided on the roller, and a driving component for driving the rotating shaft is provided on the side of one of the mounting brackets;

[0008] A bracket is fixedly connected to both sides of the mounting bracket, and a spraying component is provided on each of the two brackets. The spraying component is provided with a unclogging device for cleaning the spraying component.

[0009] Furthermore, the cleaning mechanism includes several mounting holes formed on the surface of the roller. The mounting holes are circular openings that extend through both ends of the roller. A connecting rod is movably inserted into the mounting hole, and a brush is fixedly connected to the connecting rod. Limiting members for restricting the movement of the connecting rod are provided at both ends of the roller.

[0010] Furthermore, the limiting component includes a limiting plate disposed on the rotating shaft. The limiting plate is rotatably connected to the rotating shaft and abuts against one side of the roller. An avoidance hole matching the mounting hole is provided on the limiting plate. A fixing component for fixing the limiting plate is provided on one side of the roller.

[0011] Furthermore, the fixing component includes a positioning glass bead embedded in one end of the roller, and a positioning hole is provided on the limiting plate, wherein the positioning glass bead and the positioning hole are engaged with each other.

[0012] Furthermore, the spraying assembly includes a fixed pipe, which is fixedly connected to a bracket. Several nozzles are fixedly connected to the lower end of the fixed pipe, and the nozzles are in communication with the fixed pipe. The unblocking component is located inside the fixed pipe and is used to unblock the nozzles.

[0013] Furthermore, the unblocking component includes a sealing plate disposed inside the fixed pipe, the sealing plate being slidably connected to the fixed pipe, a plurality of unblocking guide rods being fixedly connected to the lower end of the sealing plate, a pressing block being fixedly connected to the upper end of the sealing plate, the pressing block passing through the fixed pipe, and a return spring being fixedly connected to the lower end of the sealing plate.

[0014] The present invention provides a cleaning device for photovoltaic panels, which has the following advantages: When the brush wears out after working for a long time and needs to be replaced, the limiting component releases the restriction on the connecting rod, allowing the brush to be removed and a new brush to be installed on the connecting rod. The connecting rod is then reinserted into the mounting hole, and the limiting component is reset.

[0015] Secondly, in this invention, when the nozzle needs to be cleared, the sealing plate is pushed down by the pressing block, and the clearing guide rod moves to the position of the nozzle to perform the clearing operation. After the clearing is completed, the pressing block is released, and the reset spring pushes the sealing plate back to the initial position. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A cleaning device for photovoltaic panels includes a connecting plate 1 connected to a water truck. The device is characterized by: two mounting brackets 11 fixedly connected to the lower end of the connecting plate 1; rotating shafts 12 rotatably connected to each of the two mounting brackets 11; a roller 13 fixedly connected between the two rotating shafts 12; a cleaning mechanism 2 mounted on the roller 13; and a driving component 14 (a motor) for driving the rotating shafts 12 to rotate, located on the side of one of the mounting brackets 11. In this embodiment, the cleaning device is mounted on a water truck, connected to the water truck via the connecting plate 1. The water truck supplies water to the cleaning device, and the driving component 14 drives the rotating shafts 12 to rotate, which in turn drives the rollers 13 to rotate, and the cleaning mechanism 2 to rotate. The photovoltaic panels are then cleaned by the movement of the water truck.

[0025] A bracket 15 is fixedly connected to both sides of the mounting bracket 11. A spraying component 3 is provided on each of the two brackets 15. A unclogging component 4 for cleaning the spraying component 3 is provided on the spraying component 3. In this utility model, water is sprayed onto the surface of the photovoltaic panel by the spraying component 3, and then cleaned by the cleaning mechanism 2. When the spraying component 3 is blocked, it can be unclogged by the unclogging component 4 to ensure that the water spraying function is normal.

[0026] Furthermore, the cleaning mechanism 2 includes several mounting holes 21 formed on the surface of the roller 13. The mounting holes 21 are circular openings that extend through both ends of the roller 13. A connecting rod 22 is movably inserted into the mounting hole 21, and a brush 23 is fixedly connected to the connecting rod 22. In this embodiment, the diameter of the connecting rod 22 is smaller than the opening of the mounting hole 21. Limiting members 24 for restricting the movement of the connecting rod 22 are provided at both ends of the roller 13. In this utility model, when the brush 23 wears out after long-term operation and needs to be replaced, the limitation on the connecting rod 22 is released by the limiting member 24, and then the brush 23 is taken out and a new brush 23 is installed on the connecting rod 22. The connecting rod 22 is then reinserted into the mounting hole 21, and the limiting member 24 is reset.

[0027] Furthermore, the limiting member 24 includes a limiting plate 241 disposed on the rotating shaft 12. The limiting plate 241 is rotatably connected to the rotating shaft 12 and abuts against one side of the roller 13. An avoidance hole 242 matching the mounting hole 21 is provided on the limiting plate 241. A fixing member 25 for fixing the limiting plate 241 is provided on one side of the roller 13. In this utility model, when it is necessary to replace the brush 23, the limiting plate 241 can be released by fixing member 25. By rotating the limiting plate 241, the avoidance hole 242 is made to coincide with the mounting hole 21. Then, the connecting rod 22 is taken out, the new brush 23 is installed on the connecting rod 22, the connecting rod 22 with the new brush 23 is reinserted into the mounting hole 21, the limiting plate 241 is rotated to return to its original position, that is, the avoidance hole 242 no longer coincides with the mounting hole 21. Then, the limiting plate 241 is fixed again by fixing member 25, so that it restricts the movement of the connecting rod 22 again.

[0028] The fixing member 25 includes a positioning glass bead 251 embedded in one end of the roller 13, and a positioning hole 252 is provided on the limiting plate 241. The positioning glass bead 251 and the positioning hole 252 are engaged with each other. In this utility model, when it is necessary to fix the limiting plate 241, the positioning hole 252 is aligned with the positioning glass bead 251 so that it is engaged in the positioning hole, thereby fixing the limiting plate 241. When it is necessary to release the limiting plate 241, the positioning glass bead 251 is pressed to disengage it from the positioning hole 252.

[0029] In addition, the spraying assembly 3 includes a fixed pipe 31, which is fixedly connected to the bracket 15. In this embodiment, one end of the fixed pipe 31 is connected to the water pump of the water truck through a water pipe. A plurality of nozzles 32 are fixedly connected to the lower end of the fixed pipe 31. The nozzles 32 are connected to the fixed pipe 31. The unblocking component 4 is located inside the fixed pipe 31 and is used to unblock the nozzles 32. In this utility model, the liquid can be evenly sprayed onto the photovoltaic panel through the nozzles 32. When the nozzles 32 are blocked, they are unblocked by the unblocking component 4.

[0030] Furthermore, the unblocking component 4 includes a sealing plate 41 disposed inside the fixed pipe. The sealing plate 41 is slidably connected to the fixed pipe 31. Several unblocking guide rods 42 are fixedly connected to the lower end of the sealing plate 41, and a pressing block 43 is fixedly connected to the upper end of the sealing plate 41. The pressing block 43 passes through the fixed pipe 31, and a return spring 44 is fixedly connected to the lower end of the sealing plate 41. In this utility model, when the nozzle 32 needs to be unblocked, the sealing plate 41 is pushed downward by the pressing block 43, and the unblocking guide rods 42 move to the position of the nozzle 32 to perform the unblocking operation. After the unblocking is completed, the pressing block 43 is released, and the return spring 44 pushes the sealing plate 41 back to the initial position.

[0031] Working principle: During operation, the drive component 14 drives the rotating shaft 12 to rotate, which in turn drives the roller 13 to rotate, and the cleaning mechanism 2 to rotate. Water is sprayed onto the photovoltaic panel surface by the spraying component 3, and the photovoltaic panel is cleaned by the movement of the water truck. When the brush 23 needs to be replaced, the positioning glass bead 251 is pressed to disengage it from the positioning hole 252. By rotating the limiting plate 241, the clearance hole 242 is aligned with the mounting hole 21. Then, the connecting rod 22 is removed, and the new brush 23 is installed on the connecting rod 22. The connecting rod 22 with the new brush 23 is then repositioned. Insert the new mounting hole 21, rotate the limiting plate 241 to return it to its original position, that is, the avoidance hole 242 no longer coincides with the mounting hole 21. Then, align the positioning hole 252 with the positioning glass bead 251 and let it snap into it. Re-fix the limiting plate 241 so that it restricts the movement of the connecting rod 22 again. When the nozzle 32 needs to be cleared, push the sealing plate 41 down by pressing the block 43. The clearing guide rod 42 moves to the position of the nozzle 32 to perform the clearing operation. After the clearing is completed, release the block 43 and the reset spring 44 pushes the sealing plate 41 back to the initial position.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
