Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel cleaning, and more specifically, to a photovoltaic panel cleaning device. Background Technology

[0002] Photovoltaic panels, as a type of green energy device that directly converts solar energy into electricity, occupy an important position in the energy sector due to their high efficiency, environmental friendliness, and renewable characteristics. They are typically composed of multiple high-efficiency photovoltaic cells encapsulated together, with their surfaces covered by high-transmittance glass or special films to maximize sunlight capture and conversion into electricity. However, to ensure that photovoltaic panels are in optimal performance condition upon leaving the factory, surface cleaning is an indispensable and crucial step. This process removes dust and other impurities that may remain from the production process, ensuring a clean and flawless surface, thereby improving light transmittance, reducing energy loss, and ensuring that each photovoltaic panel is put into optimal use, laying a solid foundation for the efficient utilization of clean energy.

[0003] An existing example, such as the photovoltaic panel processing surface treatment structure disclosed in application number CN202421915638.3, includes a roller conveyor, a reserved groove, and a cleaning seat. It also includes dust inlet holes, a sponge brush strip, and an electric lifting rod. The roller conveyor has a reserved groove between the rollers at the feeding end. The cleaning seat is located in the reserved groove. The top surface of the cleaning seat has dust inlet holes at equal intervals. A crossbar is provided on the top of the cleaning seat. The top of the sponge brush strip is glued and fixed to the bottom of the crossbar.

[0004] However, the sponge brush strips will wear out after a period of use, which will affect the cleaning effect. Therefore, it is necessary to stop the machine, remove the crossbar and other structures, and then remove and replace the sponge brush strips. The replacement efficiency is low and affects the processing efficiency. Summary of the Invention

[0005] Therefore, in order to solve the problem of low efficiency in replacing cleaning parts, which affects processing efficiency, this invention provides a photovoltaic panel cleaning device, the specific technical solution of which is as follows:

[0006] A photovoltaic panel cleaning device includes a placement frame, a gantry frame, a cleaning roller, a support, a disassembly / assembly assembly, and a roller delivery assembly. The gantry frame is movably installed on both sides of the placement frame along its length and is driven by a drive assembly. Rotating shafts are rotatably installed at opposite ends within the gantry frame. The cleaning roller is coaxially arranged with the rotating shafts, and both ends of the cleaning roller are detachably connected to the rotating shafts. The gantry frame is equipped with a first drive member for driving the rotating shafts to rotate. The support is located at one end of the placement frame in the direction of movement of the gantry frame. The disassembly / assembly assembly and the roller delivery assembly are both installed on the support. The disassembly / assembly assembly is used to remove the cleaning roller from the rotating shaft and place it into the roller delivery assembly. The roller delivery assembly is used to send the removed cleaning roller away and deliver a new cleaning roller to the disassembly / assembly assembly.

[0007] By adopting the above technical solution, during cleaning, the photovoltaic panels to be cleaned are first laid on the placement rack, then the drive component is started to move the gantry frame, and at the same time the first drive component is started to drive the cleaning roller to rotate, thereby cleaning the surface of each photovoltaic panel. When the cleaning roller needs to be replaced after a period of use, during the gap when the photovoltaic panels are laid on the placement rack, the gantry frame is moved to a position directly below the support. Then, the cleaning roller is disassembled by the disassembly and assembly component and placed into the roller feeding component. Next, the replaced cleaning roller is sent away by the roller feeding component and the new cleaning roller is sent to the disassembly and assembly component. Finally, the disassembly and assembly component completes the assembly. This process does not require stopping the machine, and the replacement of the cleaning roller can be completed directly during the material loading process, which greatly improves the replacement efficiency of cleaning parts and thus improves the overall processing efficiency.

[0008] Furthermore, each of the two rotating shafts is equipped with a mounting plate at one end close to the other. The mounting plate has a mounting groove on the side away from the rotating shaft, and the mounting groove extends downward outward from the mounting plate. The end of the cleaning roller is engaged in the mounting groove from bottom to top, and the cleaning roller is detachably installed in the mounting groove by fasteners.

[0009] Furthermore, the bracket is equipped with the disassembly and assembly components at both ends. The disassembly and assembly components include a mounting bracket, a screwdriver, an arc-shaped bracket, and a second driving component. The fasteners include fastening bolts, which pass through the cleaning roller and the mounting plate simultaneously from bottom to top, and are threaded onto both the cleaning roller and the mounting plate. The mounting bracket is slidably mounted on the bracket in a vertical direction, and the second driving component is used to drive the mounting bracket to slide. The screwdriver and the arc-shaped bracket are horizontally spaced on the mounting bracket, with the working end of the screwdriver facing vertically upward and directly opposite the head of the fastening bolt, and the inner arc surface of the arc-shaped bracket facing directly below the end of the cleaning roller.

[0010] Furthermore, the roller feeding assembly is positioned between the two disassembly and assembly assemblies. The roller feeding assembly includes a steering shaft, a plurality of dividing plates, and a third driving member. The steering shaft extends along the length direction of the cleaning roller and is rotatably mounted on the bracket. The third driving member is used to drive the steering shaft to rotate. The plurality of dividing plates are arranged circumferentially along the steering shaft, and each dividing plate divides into multiple first placement spaces, wherein one of the first placement spaces faces vertically upward.

[0011] Furthermore, the steering shaft is equipped with a plurality of plug-in rods corresponding to the positions in each of the first placement spaces, and the cleaning roller is provided with a plug-in groove at the position corresponding to each of the plug-in rods, and the plug-in rod is inserted into the plug-in groove.

[0012] Furthermore, an auxiliary rail is installed in the middle of the placement rack, and the placement rack is divided into two rows of second placement spaces for placing photovoltaic panels by the auxiliary rail. A conveying mechanism is provided directly below each of the second placement spaces on the placement rack. The photovoltaic panel cleaning device also includes an unloading component for unloading the photovoltaic panels that have been cleaned in the second placement spaces onto the conveying mechanism.

[0013] Furthermore, the unloading assembly includes a support frame and a fourth driving member. The support frame is provided on both sides of the two second placement spaces. The two support frames in the same second placement space slide towards each other or away from each other. The fourth driving member is used to drive the support frame to slide.

[0014] Furthermore, the conveying mechanism includes a frame and a pair of belt conveyors, the frame extending along the length of the second placement space, and the two belt conveyors being spaced apart on both sides of the frame.

[0015] Furthermore, the unloading assembly includes several pallets and a fifth drive component. The pallets are positioned between the two belt conveyors, and the several pallets are spaced apart along the length of the frame. The pallets are movably mounted on the frame in a vertical direction, and the fifth drive component is used to drive the pallets to move.

[0016] Furthermore, a dust suction hood is fixedly installed inside the gantry frame and directly above the sweeping roller. The opening of the dust suction hood faces downward, and a dust suction pipe is connected to the top of the dust suction hood. The end of the dust suction pipe away from the dust suction hood is used to connect to a vacuum cleaner. Attached Figure Description

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] In this invention, the terms "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0024] like Figure 1 and Figure 2 As shown, a photovoltaic panel cleaning device according to one embodiment of the present invention includes a placement frame 1, a gantry frame 2, a cleaning roller 3, a support 4, a disassembly and assembly assembly 5, and a roller feeding assembly 6. The gantry frame 2 is movably installed on both sides of the placement frame 1 along the length direction of the placement frame 1, and the gantry frame 2 is driven to move by a drive assembly 7. Rotating shafts 21 are rotatably installed at opposite ends inside the gantry frame 2, and the rotating shafts 21 extend horizontally perpendicular to the length direction of the placement frame 1. The cleaning roller 3 is a brush roller (bristles not shown in the figure), and the cleaning roller 3 is coaxially arranged with the rotating shaft 21. The ends are detachably connected to two rotating shafts 21 respectively; the gantry frame 2 is equipped with a first driving component 22 for driving the rotating shafts 21 to rotate. The first driving component 22 is a belt drive motor module, which is existing technology and will not be described in detail here; the bracket 4 is set at one end of the placement frame 1 in the moving direction of the gantry frame 2. The disassembly and assembly component 5 and the roller feeding component 6 are both installed on the bracket 4. The disassembly and assembly component 5 is used to remove the cleaning roller 3 from the rotating shaft 21 and put it into the roller feeding component 6. The roller feeding component 6 is used to send the replaced cleaning roller 3 away and send the new cleaning roller 3 to the disassembly and assembly component 5.

[0025] During cleaning, the photovoltaic panels to be cleaned are first laid on the placement rack 1. Then, the first drive component 7 is activated to move the gantry 2. At the same time, the first drive component 22 is activated to rotate the cleaning roller 3, thereby cleaning the surface of each photovoltaic panel. When the cleaning roller 3 needs to be replaced after a period of use, the gantry 2 is moved to the position directly below the support 4 during the gap when the photovoltaic panels are laid on the placement rack 1. Then, the cleaning roller 3 is disassembled through the disassembly and assembly component 5 and placed into the roller feeding component 6. Next, the replaced cleaning roller 3 is sent away through the roller feeding component 6 and the new cleaning roller 3 is sent to the disassembly and assembly component 5. Finally, the disassembly and assembly component 5 completes the assembly. This process does not require stopping the machine. The replacement of the cleaning roller 3 can be completed directly during the material feeding process, which greatly improves the replacement efficiency of cleaning parts and thus improves the overall processing efficiency.

[0026] Specifically, such as Figure 2 and Figure 3As shown, mounting discs 23 are coaxially fixed at the ends of the two rotating shafts 21 that are close to each other. A mounting groove 231 is provided on the side of the mounting disc 23 away from the rotating shaft 21. The mounting groove 231 extends downward outward from the mounting disc 23. The end of the sweeping roller 3 is engaged in the mounting groove 231 from bottom to top. The sweeping roller 3 is installed in the mounting groove 231 in a detachable manner by fasteners. The sweeping roller 3 can be removed from the mounting groove 231 by loosening the fasteners. The sweeping roller 3 is easy to remove from the mounting groove 231.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, both ends of the bracket 4 are equipped with disassembly and assembly components 5. The disassembly and assembly components 5 include a mounting bracket 51, a screwdriver 52, an arc-shaped bracket 53, and a second driving component 54. Fasteners include fastening bolts 31, which pass through the cleaning roller 3 and the mounting plate 23 from bottom to top, and are threaded onto both the cleaning roller 3 and the mounting plate 23. The mounting bracket 51 is slidably mounted on the bracket 4 in a vertical direction. The second driving component 54 is used to drive the mounting bracket 51 to slide. In this embodiment, the second driving component 54 is a cylinder, and the piston rod of the second driving component 54 is fixedly mounted on the mounting bracket 51. The screwdriver 52 and the arc-shaped bracket 53 are horizontally spaced on the mounting bracket 51, and the screwdriver 52 and the arc-shaped bracket 53 are also mounted on the mounting bracket 51. The screwdriver 52 is arranged along the length of the sweeping roller 3, with its working end facing vertically upwards and directly opposite the head of the fastening bolt 31. The inner arc surface of the arc bracket 53 faces directly below the end of the sweeping roller 3, and the inner arc surface of the arc bracket 53 is provided with a rubber layer. When the gantry 2 moves to the position directly below the bracket 4, the second drive component 54 is activated, causing the mounting bracket 51 to slide vertically upwards until the arc bracket 53 supports the sweeping roller 3, and the working end of the screwdriver 52 is engaged with the head of the fastening bolt 31. The screwdriver 52 is then activated to unscrew the fastening bolt 31 from the mounting plate 23. Then, the second drive component 54 is activated again, causing the mounting bracket 51 to slide vertically downwards, and the sweeping roller 3 can be detached from the mounting plate 23, completing the removal.

[0028] Specifically, such as Figure 2 , Figure 4 and Figure 5As shown, the roller feeding assembly 6 is positioned between the two disassembly / assembly assemblies 5. The roller feeding assembly 6 includes a steering shaft 61, several dividing plates 62, and a third drive component 63. The steering shaft 61 extends along the length of the cleaning roller 3 and is rotatably mounted on the bracket 4. The third drive component 63 is used to drive the steering shaft 61 to rotate. The third drive component 63 is a belt-driven motor module, which is prior art and will not be described in detail here. Several dividing plates 62 are arranged at intervals along the circumference of the steering shaft 61. Each dividing plate 62 divides into multiple first placement spaces 64, one of which is vertically upward. The first placement spaces 64 located on both sides in the horizontal direction are divided into... Not for loading and unloading; when the disassembly and assembly assembly 5 removes the sweeping roller 3 from the gantry 2 and moves it downward, the first vertically upward placement space 64 is empty until the sweeping roller 3 is inserted into the first placement space 64, and at the same time, a new sweeping roller 3 is placed in the first placement space 64 on one side; then the third drive unit 63 is activated to drive the steering shaft 61 to rotate, so that the first placement space 64 containing the replaced sweeping roller 3 rotates to the other side, and the new sweeping roller 3 rotates to be vertically upward; then the second drive unit 54 is activated to drive the mounting frame 51 to move upward, so that the new sweeping roller 3 can be transported into the gantry 2 to complete the assembly.

[0029] Furthermore, several plug-in rods 65 are installed at positions corresponding to each first placement space 64 on the steering shaft 61. Each plug-in rod 65 is spaced apart along the length of the steering shaft 61 and extends radially toward the steering shaft 61. Each position of the sweeping roller 3 corresponding to each plug-in rod 65 is provided with a plug-in groove 32, and the plug-in rod 65 is inserted into the plug-in groove 32. This ensures that the sweeping roller 3 is stable within the first placement space 64 and remains stable within the first placement space 64 as it rotates with the steering shaft 61.

[0030] Specifically, such as Figure 2 , Figure 3 and Figure 6 As shown, an auxiliary rail 11 is installed in the middle of the placement rack 1, and a support wheel 24 is provided in the middle of the gantry 2. The support wheel 24 is rolled on the auxiliary rail 11 to provide support and improve the stability of the gantry 2. The placement rack 1 is divided into two rows of second placement spaces 12 for placing photovoltaic panels by the auxiliary rail 11. A conveying mechanism 8 is provided directly below the second placement space 12 of the placement rack 1. The photovoltaic panel cleaning device also includes an unloading component 9 for unloading the photovoltaic panels that have been cleaned in the second placement space 12 onto the conveying mechanism 8.

[0031] The unloading assembly 9 includes a support frame 91 and a fourth drive component 92. Support frames 91 are provided on opposite sides of the two second placement spaces 12. The support frames 91 are angle iron shaped. The two support frames 91 in the same second placement space 12 slide towards each other or away from each other. The fourth drive component 92 is used to drive the support frames 91 to slide. The fourth drive component 92 includes a double-headed cylinder and a single-headed cylinder. The double-headed cylinder is installed on the auxiliary rail 11, and the two piston rods of the double-headed cylinder are respectively fixedly installed on the two support frames 91 located on both sides of the auxiliary rail 11. The single-headed cylinder is installed on both sides of the placement frame 1, and the piston rod of the single-headed cylinder is fixedly installed on the support frames 91 located on both sides of the placement frame 1. Thus, when cleaning is completed, the fourth drive component 92 can be activated to drive the two support frames 91 located in the same second placement space 12 to move away from each other, so that the support frames 91 leave the photovoltaic panel.

[0032] Furthermore, such as Figure 2 As shown, the conveying mechanism 8 includes a frame 81 and a pair of belt conveyors 82. The frame 81 extends along the length of the second placement space 12. The two belt conveyors 82 are spaced apart on both sides of the frame 81. The belt conveyors 82 are existing technology and will not be described in detail here. The unloading assembly 9 includes several pallets 93 and a fifth drive member 94. The pallets 93 are positioned between the two belt conveyors 82. The several pallets 93 are spaced apart along the length of the frame 81. The pallets 93 are vertically movable on the frame 81. The fifth drive member 94 is used to drive the pallets 93 to move. Each pallet 93... A fifth drive unit 94 is installed directly below each of the photovoltaic panels. The fifth drive unit 94 is a cylinder and is fixedly installed on the frame 81. The piston rod of the fifth drive unit 94 is fixedly installed on the bottom of the tray 93. Thus, the fifth drive unit 94 can be activated before the fourth drive unit 92 is activated, driving the tray 93 to move vertically upward to directly below the photovoltaic panel. Then, when the support frame 91 leaves the photovoltaic panel, the photovoltaic panel can fall onto the tray 93. As the tray 93 moves vertically downward, the photovoltaic panel falls onto the conveyor belt 82. The conveyor belt 82 transports the photovoltaic panel to the next process, such as packaging.

[0033] Specifically, such as Figure 2 and Figure 7 As shown, drive components 7 are installed at both ends of the gantry frame 2. The drive components 7 include a gear 71, a rack 72 and a drive motor 73. The rack 72 is fixedly installed on the placement frame 1, and the gear 71 is rotatably installed on the gantry frame 2. The gear 71 meshes with the rack 72. The output shaft of the drive motor 73 is connected to the rotating shaft of the gear 71 through a belt drive. Thus, the gantry frame 2 can be driven to move stably on the placement frame 1.

[0034] Specifically, such as Figure 2As shown, a dust suction hood 25 is fixedly installed inside the gantry frame 2 and directly above the sweeping roller 3. The opening of the dust suction hood 25 faces downward, and a dust suction pipe is connected to the top of the dust suction hood 25. The end of the dust suction pipe away from the dust suction hood 25 is used to connect to a vacuum cleaner; thus, dust can be extracted during cleaning, improving the cleaning effect.

[0035] The implementation principle of a photovoltaic panel cleaning device according to an embodiment of this application is as follows: The gantry 2 first moves to one side of the placement rack 1, and then the photovoltaic panel is placed on the placement rack 1 by means of a robotic arm or the like; then the drive motor 73 is started to drive the gantry 2 to move along the placement rack 1, and at the same time the first drive component 22 is started to drive the cleaning roller 3 to rotate, thereby cleaning the surface of each photovoltaic panel; then the fifth drive component 94 drives the tray 93 to move vertically upward to directly below the photovoltaic panel, and then the fourth drive component 92 is started to drive the support frame 91 to leave the photovoltaic panel, so that the photovoltaic panel can fall on the tray 93, and move vertically downward with the tray 93 until the photovoltaic panel falls on the belt conveyor 82, and the belt conveyor 82 transports the photovoltaic panel to the next process; when the cleaning roller 3 needs to be replaced after a period of use, the gantry 2 is driven to move to the position directly below the support 4 during the time interval of laying the photovoltaic panel on the placement rack 1.

[0036] Then, the second drive unit 54 is activated, causing the mounting bracket 51 to slide vertically upwards until the arc-shaped bracket 53 supports the sweeping roller 3, and the working end of the screwdriver 52 engages with the head of the fastening bolt 31. The screwdriver 52 is then activated to loosen the fastening bolt 31 from the mounting plate 23. Next, the second drive unit 54 is activated again, causing the mounting bracket 51 to slide vertically downwards until the sweeping roller 3 is engaged in the first placement space 64. At the same time, a new sweeping roller 3 is placed in the first placement space 64 located on one side. Then, the third drive unit 63 is activated, causing the steering shaft 61 to rotate, so that the first placement space 64 containing the replaced sweeping roller 3 rotates to the other side, and the new sweeping roller 3 rotates to face vertically upwards. Next, the second drive unit 54 is activated, causing the mounting bracket 51 to move upwards, so that the new sweeping roller 3 can be transported into the gantry 2. Finally, the assembly is completed by using the screwdriver 52.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
