Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel dust removal, and particularly to a photovoltaic cleaning robot and a control method for photovoltaic panel dust removal. Background Technique

[0002] Photovoltaic power generation is an important way to obtain sustainable energy. When various pollutants such as dust, stains, and bird droppings adhere to the surface of photovoltaic panels, it will seriously hinder the effective irradiation of light, thereby reducing the photoelectric conversion efficiency of the photovoltaic panels. Therefore, it is necessary to clean the pollutants on the surface of the photovoltaic panels through a photovoltaic cleaning robot.

[0003] When performing dust removal operations on large photovoltaic panels, guide rails are usually installed on the photovoltaic panels, so that the photovoltaic cleaning robot moves under the guidance of the guide rails and removes dust from the surface of the photovoltaic panels. Since the overall length of the existing photovoltaic cleaning robot is fixed, the overall length of the photovoltaic cleaning robot cannot be adjusted according to the width of the photovoltaic panel. This phenomenon results in that the cleaning robot can only adapt to a certain specific specification of photovoltaic panel and is difficult to meet the diverse application requirements.

[0004] For the problems in the related technology, no effective solution has been proposed yet. Summary of the Invention

The cleaning components and the dust suction components are arranged alternately front and back. Socket frames are fixedly installed on both sides of the adjustable outer shell assembly. Moving components are arranged inside the two socket frames. Linkage components are arranged between the two moving components and the corresponding cleaning components;

[0010] When adjusting the overall length of the adjustable housing assembly, the two cleaning components and the two dust suction components arranged staggeredly move horizontally. The socket frame is used for the adjustable housing assembly to be sleeved on the photovoltaic panel. While the moving component drives the adjustable housing assembly to move on the photovoltaic panel through the socket frame, it drives the two cleaning components to rotate inside the adjustable housing assembly through the linkage component.

[0011] Preferably, the cleaning component includes a rotating shaft, and the rotating shaft is arranged on the inner walls of both the adjusting housing and the supporting housing. Fixedly connected to the opposite ends of the two rotating shafts are brush rollers. Fixedly installed on the top inner walls of both the adjusting housing and the supporting housing are cleaning support frames. The outer surfaces of the two cleaning support frames are movably connected with mounting plates, and the opposite ends of the two brush rollers are rotatably connected to the corresponding mounting plates.

[0012] Preferably, the dust suction component includes a dust suction frame, and the dust suction frame is arranged on the inner walls of both the adjusting housing and the supporting housing. Fixedly connected to the bottoms of the two dust suction frames are dust suction covers, and a plurality of dust suction covers are arranged in an array at the bottoms corresponding to the dust suction frames. A suction pipe is arranged at the top of the dust suction frame, and a number of branch pipes are fixedly connected to the outer surface of the suction pipe corresponding to the dust suction covers. The bottom ends of the number of branch pipes extend into the corresponding dust suction covers. Fixedly installed on the top inner walls of both the adjusting housing and the supporting housing are dust suction support frames, and the opposite sides of the dust suction frames are movably connected to the corresponding dust suction support frames.

[0013] Preferably, adsorption boxes are fixedly installed on the tops of both the adjusting housing and the supporting housing. Fixedly installed on the opposite sides of the two adsorption boxes are exhaust fans, and the two suction pipes are connected to the corresponding adsorption boxes. A through groove is formed in the front of the adsorption box, and a placement frame is fixedly connected to the inner wall of the adsorption box corresponding to the through groove. A collection box is movably connected inside the placement frame and the through groove, and filters are arranged on both sides and the bottom of the collection box.

[0014] Preferably, the moving component includes rotating rollers, the shaft heads of the rotating rollers are rotatably connected to the socket frame, and a number of rotating rollers are arranged in an array inside the socket frame. Fixedly connected to the outer surfaces of the shaft heads of the number of rotating rollers are sprockets, and chains are engaged with the outer surfaces of the sprockets. A motor is fixedly installed on the outside of the socket frame, and the motor is fixedly connected to the shaft head of the rotating roller.

[0015] Preferably, the linkage component includes a driving gear, the driving gear is fixedly connected to the shaft head of one of the rotating rollers, a driven gear is engaged with the outer surface of the driving gear, and the corresponding rotating shaft is fixedly connected to the driven gear.

[0016] Preferably, sleeves are fixedly installed on the outer sides of the adjustment housing and the support housing. The two rotating rollers are rotatably connected to the corresponding sleeves. One end of the sleeve is fixedly connected to a protective box. The driving gear and the driven gear are both located inside the protective box. A protective frame is fixedly installed on the outer side of the socket frame corresponding to the sprocket and the chain.

[0017] A control method for dust removal of a photovoltaic panel based on the photovoltaic cleaning robot:

[0018] By rotating the adjustment screw, the adjustment screw continuously moves out of the adjustment cylinder, so that the adjustment housing and the support housing can drive the corresponding brush rollers and dust suction frames to move synchronously.

[0019] When the adjustment housing and the support housing are adjusted according to the length of the photovoltaic panel, the two socket frames are sleeved on the guide rails erected on both sides of the photovoltaic panel. At this time, several rotating rollers arranged inside the socket frame are in contact with the top and bottom of the guide rail.

[0020] By driving the motor, the motor drives all the rotating rollers to rotate through the sprocket and the chain. Under the rotation of the rotating rollers, the adjustment housing and the support housing can move on the photovoltaic panel.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a photovoltaic cleaning robot and a control method for dust removal of a photovoltaic panel, which have the following beneficial effects:

[0024] 1. The present invention enables the cleaning robot to be adjusted according to the width of the photovoltaic panel through the adjustable housing assembly. At the same time, when the adjustable housing assembly is adjusted, it can drive the two cleaning assemblies and the dust suction assembly to move in opposite directions, so that the two cleaning assemblies and the dust suction assembly can fully cover the path of the movement of the adjustable housing assembly. The above settings enable the cleaning robot to adapt to different specifications of photovoltaic panels, and the cleaning effect of the cleaning robot will not be affected when cleaning the photovoltaic panel.

[0025] 2. By rotating the adjusting screw rod, the length between the adjusting housing, the connecting housing and the supporting housing can be adjusted. At the same time, the adjusting housing and the supporting housing can drive the corresponding brush rollers and dust suction frames to be adjusted together. When cleaning the photovoltaic panel, the two staggeredly arranged brush rollers can clean the pollutants adhered to the surface of the photovoltaic panel. As the adjusting housing and the supporting housing move continuously, several dust suction covers arranged at the bottoms of the two dust suction frames can suck the cleaned pollutants. The above settings ensure that no matter how the adjusting housing and the supporting housing are adjusted, the cleaning effect of the brush rollers and the dust suction covers on the pollutants on the surface of the photovoltaic panel can be guaranteed.

[0026] 3. By erecting guide rails on both sides of the photovoltaic panel, when cleaning the photovoltaic panel, directly sleeved the two socket frames on the outer surface of the guide rails, and then driven by the motor, sprockets, chains and rotating rollers, the lower socket frame can move on the guide rails, and the adjusting housing and the supporting housing can move on the photovoltaic panel driven by the two socket frames. Since the socket frame can be directly sleeved on the outer surface of the guide rail, it is more convenient to install the cleaning robot on the photovoltaic panel.

[0027] 4. Through the driving gear and the driven gear, the rotating shaft can drive the brush roller to rotate, so that the brush roller can rotate while moving. This setting improves the cleaning effect when cleaning the photovoltaic panel. At the same time, when cleaning photovoltaic panels with different pollution degrees, only need to adjust the moving speed of the cleaning robot, and the rotating speed of the brush roller can be adjusted together, and the overall operation is more convenient.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a photovoltaic cleaning robot and a control method for dust removal of photovoltaic panels.

[0039] Please refer to Figures 1-8 , a photovoltaic cleaning robot, including an adjustable housing assembly 1. Both sides of the inner wall of the adjustable housing assembly 1 are provided with a cleaning component 2 and a dust suction component 3. The cleaning component 2 and the dust suction component 3 are arranged in a staggered manner front and back. Socket frames 4 are fixedly installed on both sides of the adjustable housing assembly 1. Mobile components 5 are arranged inside both of the socket frames 4. A linkage component 6 is arranged between the two mobile components 5 and the corresponding cleaning components 2;

[0040] When the overall length of the adjustable housing assembly 1 is adjusted, the two cleaning components 2 and the two dust suction components 3 arranged in a staggered manner move horizontally. The socket frames 4 are used for the adjustable housing assembly 1 to be sleeved on the photovoltaic panel. While the mobile component 5 drives the adjustable housing assembly 1 to move on the photovoltaic panel through the socket frame 4, it drives the two cleaning components 2 to rotate inside the adjustable housing assembly 1 through the linkage component 6.

[0041] When cleaning the surface of a photovoltaic panel with a cleaning robot, the overall length of the adjustable outer shell assembly 1 is adjusted according to the length of the photovoltaic panel. When the length of the adjustable outer shell assembly 1 is adjusted, it can drive the corresponding cleaning assembly 2 and dust suction assembly 3 to move. After the length adjustment of the adjustable outer shell assembly 1 is completed, the socket frames 4 provided on both sides of the adjustable outer shell assembly 1 are sleeved on the guide rails installed on both sides of the photovoltaic panel. At this time, the cleaning ends of the two cleaning assemblies 2 can be in contact with the surface of the photovoltaic panel. Then, the moving assembly 5 is driven, so that the moving assembly 5 drives the socket frame 4 to move on the guide rail, and the two socket frames 4 drive the cleaning assembly 2 and the dust suction assembly 3 to move on the photovoltaic panel through the adjustable outer shell assembly 1. At the same time, the moving assembly 5 can drive the two cleaning assemblies 2 to rotate through the linkage assembly 6, so that the two cleaning assemblies 2 can clean the pollutants on the photovoltaic panel, and the dust suction assembly 3 sucks the cleaned pollutants.

[0042] The adjustable outer shell assembly 1 enables the cleaning robot to be adjusted according to the width of the photovoltaic panel. At the same time, when the adjustable outer shell assembly 1 is adjusted, it can drive the two cleaning assemblies 2 and the dust suction assembly 3 to move in opposite directions, so that the two cleaning assemblies 2 and the dust suction assembly 3 can fully cover the path of the movement of the adjustable outer shell assembly 1. The above settings enable the cleaning robot to adapt to photovoltaic panels of different specifications, and the cleaning effect of the cleaning robot will not be affected when cleaning the photovoltaic panel.

[0043] Further, for the above-mentioned adjustable outer shell assembly 1, the adjustable outer shell assembly 1 includes an adjustment outer shell 101. A storage groove 102 is formed inside the adjustment outer shell 101. A connection shell 103 is movably connected inside the storage groove 102. A support outer shell 104 is fixedly connected to one side of the connection shell 103. An adjustment screw 105 is rotatably connected to the back of the support outer shell 104. An adjustment cylinder 106 is fixedly connected to the back of the adjustment outer shell 101. The adjustment screw 105 is threadedly connected to the adjustment cylinder 106.

[0044] By rotating the adjusting screw 105, the adjusting screw 105 can continuously move out from the inside of the adjusting cylinder 106. At this time, driven by the adjusting cylinder 106, the length between the adjusting housing 101 and the supporting housing 104 can be adjusted. Meanwhile, the connecting shell 103 continuously moves out from the inside of the receiving groove 102 driven by the supporting housing 104, so that the length between the adjusting housing 101, the connecting shell 103 and the supporting housing 104 can be adjusted according to the width of the photovoltaic panel. In the above setting, the receiving groove 102 and the connecting shell 103 ensure the stability of the overall movement when the adjusting housing 101 and the supporting housing 104 are adjusted. At the same time, the connecting shell 103 enables the adjusting housing 101 and the supporting housing 104 to still cover the cleaning component 2 and the dust suction component 3 after the adjustment, so that there will be no dust raising phenomenon when the cleaning component 2 cleans the pollutants on the photovoltaic panel, and the effect of the dust suction component 3 adsorbing the cleaned pollutants can also be ensured.

[0045] Further, for the above-mentioned cleaning component 2, the cleaning component 2 includes a rotating shaft 201. The rotating shaft 201 is provided on the inner walls of both the adjusting housing 101 and the supporting housing 104. Fixedly connected to the opposite ends of the two rotating shafts 201 are brush rollers 202. Fixedly installed on the top of the inner walls of both the adjusting housing 101 and the supporting housing 104 are cleaning support frames 203. The outer surfaces of the two cleaning support frames 203 are movably connected with mounting plates 204. The opposite ends of the two brush rollers 202 are rotatably connected to the corresponding mounting plates 204.

[0046] When the lengths of the adjusting housing 101 and the supporting housing 104 are adjusted, the adjusting housing 101 and the supporting housing 104 drive the two brush rollers 202 to move through the corresponding rotating shafts 201. This setting enables the overall length of the two staggered brush rollers 202 to be adjusted together after the length between the adjusting housing 101 and the supporting housing 104 is adjusted. When the lengths of the two brush rollers 202 are adjusted, the two brush rollers 202 can drive the mounting plates 204 at their respective ends to move on the corresponding cleaning support frames 203. This setting ensures the overall stability of the two brush rollers 202 after the adjustment. When the socket frame 4 is sleeved on the guide rails erected on both sides of the photovoltaic panel, the two brush rollers 202 can be in contact with the surface of the photovoltaic panel. When the adjusting housing 101 and the supporting housing 104 move on the photovoltaic panel, the two brush rollers 202 can rotate driven by the corresponding rotating shafts 201, so that the two brush rollers 202 can clean the pollutants adhering to the photovoltaic panel.

[0047] Further, for the above-mentioned dust suction assembly 3, the dust suction assembly 3 includes a dust suction frame 301, and the dust suction frame 301 is provided on the inner walls of both the adjustment housing 101 and the support housing 104. A dust suction hood 302 is fixedly connected to the bottom of the two dust suction frames 301. A plurality of the dust suction hoods 302 are arranged in an array corresponding to the bottom of the dust suction frame 301. An extraction pipe 303 is provided at the top of the dust suction frame 301. A number of branch pipes 304 are fixedly connected to the outer surface of the extraction pipe 303 corresponding to the dust suction hood 302. The bottom ends of the number of branch pipes 304 extend into the corresponding dust suction hood 302. Dust suction support frames 305 are fixedly installed at the top of the inner walls of both the adjustment housing 101 and the support housing 104. The opposite sides of the dust suction frame 301 are movably connected to the corresponding dust suction support frames 305.

[0048] When the adjustment housing 101 and the support housing 104 are adjusted in length, the adjustment housing 101 and the support housing 104 can drive the corresponding dust suction frame 301 to move. At the same time, the two dust suction frames 301 can slide on the outer surface of the corresponding dust suction support frames 305. This setting enables the overall length of the two staggered dust suction frames 301 to always be consistent with the two staggered brush rollers 202. When cleaning the photovoltaic panel, after the two rotating brush rollers 202 clean the pollutants adhering to the photovoltaic panel, a number of dust suction hoods 302 provided at the bottom of the two dust suction frames 301 can suck the cleaned pollutants. Since a plurality of dust suction hoods 302 are arranged in an array at the bottom of the dust suction frame 301, the force distribution during the suction of the cleaned pollutants is more uniform. This setting ensures the effect of sucking the pollutants cleaned from the photovoltaic panel.

[0049] Further, for the above-mentioned adjustment housing 101, adsorption boxes 306 are fixedly installed at the tops of both the adjustment housing 101 and the support housing 104. Exhaust fans 307 are fixedly installed on the opposite sides of the two adsorption boxes 306. The two extraction pipes 303 are connected to the corresponding adsorption boxes 306. A through groove 308 is formed in the front of the adsorption box 306. A placement frame 309 is fixedly connected to the inner wall of the adsorption box 306 corresponding to the through groove 308. A collection box 310 is movably connected inside the placement frame 309 and the through groove 308. Filter screens 311 are provided on both sides and the bottom of the collection box 310.

[0050] The air inside the adsorption box 306 is adsorbed by the exhaust fan 307, so that the inside of the adsorption box 306 is in a negative pressure state. At this time, the suction pipe 303 connected to the adsorption box 306 generates suction force, so that the suction pipe 303 extracts the pollutants and dust cleaned through a plurality of branch pipes 304 and the dust suction hood 302. The extracted pollutants and dust can directly fall into the inside of the collection box 310 under the guidance of the suction pipe 303; through the through groove 308 and the placement frame 309, the collection box 310 can be moved into the inside of the adsorption box 306. Under the support of the placement frame 309, there is no obstruction on both sides and the bottom of the collection box 310. This setting enables the exhaust fan 307 to better extract the air inside the collection box 310 through the filter screen 311.

[0051] Further, for the above-mentioned moving assembly 5, the moving assembly 5 includes a rotating roller 501. The shaft head of the rotating roller 501 is rotatably connected to the socket frame 4. A plurality of rotating rollers 501 are arranged in an array inside the socket frame 4. Fixedly connected to the outer surface of the shaft heads of several rotating rollers 501 are sprockets 502. Engaged with the outer surface of the sprocket 502 is a chain 503. Fixedly installed on the outside of the socket frame 4 is a motor 504, and the motor 504 is fixedly connected to the shaft head of the rotating roller 501.

[0052] By erecting guide rails on both sides of the photovoltaic panel, when cleaning the photovoltaic panel, the two socket frames 4 are directly moved to the outer surface of the guide rail through one end of the guide rail. At this time, the two layers of rotating rollers 501 arranged up and down inside the socket frame 4 are respectively in contact with the top and bottom of the wire guide rail. Then the motor 504 is driven. The motor 504 can drive one of the rotating rollers 501 to rotate. The rotating roller 501 drives all the rotating rollers 501 in the upper layer to rotate through the sprocket 502 and the chain 503. Driven by the rotating roller 501, the socket frame 4 can move on the guide rail. At the same time, the adjustment housing 101 and the support housing 104 can move on the photovoltaic panel driven by the two socket frames 4. Since the socket frame 4 can be directly sleeved on the outer surface of the guide rail, it is more convenient to install the cleaning robot on the photovoltaic panel; at the same time, when the guide rail is erected, both ends of the guide rail are outside the photovoltaic panel. This setting enables the cleaning robot to better cover the photovoltaic panel when moving under the guidance of the guide rail.

[0053] Further, for the above-mentioned linkage assembly 6, the linkage assembly 6 includes a driving gear 601. The driving gear 601 is fixedly connected to the shaft head of one of the rotating rollers 501. Engaged with the outer surface of the driving gear 601 is a driven gear 602, and the corresponding rotating shaft 201 is fixedly connected to the driven gear 602.

[0054] When the rotating roller 501 rotates, the rotating roller 501 can drive the driven gear 602 to rotate through the driving gear 601. The rotating driven gear 602 can drive the brush roller 202 to rotate through the rotating shaft 201, so that the brush roller 202 can rotate while moving. This setting improves the cleaning effect on the photovoltaic panel. At the same time, with the assistance of the driving gear 601 and the driven gear 602, the rotation speed of the brush roller 202 can be adjusted according to the moving speed of the cleaning robot. This setting enables when cleaning photovoltaic panels with different pollution degrees, only by adjusting the moving speed of the cleaning robot, the rotation speed of the brush roller 202 can be adjusted together, and the overall operation is relatively convenient.

[0055] Furthermore, for the above-mentioned adjustment housing 101, sleeves 7 are fixedly installed on the outer sides of both the adjustment housing 101 and the support housing 104. The two rotating rollers 501 are rotatably connected to the corresponding sleeves 7. One end of the sleeve 7 is fixedly connected to a protective box 8. The driving gear 601 and the driven gear 602 are both located inside the protective box 8. A protective frame 9 is fixedly installed on the outer side of the socket frame 4 corresponding to the sprocket 502 and the chain 503.

[0056] The sleeve 7 can support the rotating roller 501, so that the overall stability can be ensured when the driving gear 601 and the driven gear 602 drive the rotating roller 501 to rotate. At the same time, the protective box 8 can protect the driving gear 601 and the driven gear 602, and the protective frame 9 can protect the sprocket 502 and the chain 503. This setting enables that when the cleaning robot is in use, the driving gear 601, the driven gear 602, the sprocket 502 and the chain 503 will not get stuck due to dust accumulation.

[0057] Through the above technical solutions: 1. The adjustable outer shell assembly 1 enables the cleaning robot to be adjusted according to the width of the photovoltaic panel. When the adjustable outer shell assembly 1 is adjusted, it can drive the two cleaning assemblies 2 and the dust suction assembly 3 to move in opposite directions, so that the two cleaning assemblies 2 and the dust suction assembly 3 can fully cover the path of the movement of the adjustable outer shell assembly 1. The above settings enable the cleaning robot to adapt to different specifications of photovoltaic panels, and the cleaning effect of the cleaning robot on the photovoltaic panel will not be affected; 2. By rotating the adjusting screw 105, the length between the adjusting outer shell 101, the connecting shell 103 and the supporting outer shell 104 can be adjusted. At the same time, the adjusting outer shell 101 and the supporting outer shell 104 can drive the corresponding brush rollers 202 and the dust suction frames 301 to be adjusted together. When cleaning the photovoltaic panel, the two staggered brush rollers 202 can clean the pollutants adhered to the surface of the photovoltaic panel. As the adjusting outer shell 101 and the supporting outer shell 104 keep moving, several dust suction covers 302 arranged at the bottom of the two dust suction frames 301 can suck the cleaned pollutants. The above settings ensure that no matter how the adjusting outer shell 101 and the supporting outer shell 104 are adjusted, the cleaning effect of the brush rollers 202 and the dust suction covers 302 on the surface pollutants of the photovoltaic panel can be guaranteed; 3. By installing guide rails on both sides of the photovoltaic panel, when cleaning the photovoltaic panel, directly sleeved the two socket frames 4 on the outer surface of the guide rails, and then driven by the motor 504, the sprocket 502, the chain 503 and the rotating roller 501, the lower socket frame 4 can move on the guide rails, and the adjusting outer shell 101 and the supporting outer shell 104 can move on the photovoltaic panel driven by the two socket frames 4. Since the socket frame 4 can be directly sleeved on the outer surface of the guide rails, it is more convenient to install the cleaning robot on the photovoltaic panel; 4. The driving gear 601 and the driven gear 602 enable the rotating shaft 201 to drive the brush roller 202 to rotate, so that the brush roller 202 can rotate while moving. This setting improves the cleaning effect on the photovoltaic panel. At the same time, when cleaning photovoltaic panels with different pollution degrees, only by adjusting the moving speed of the cleaning robot, the rotating speed of the brush roller 202 can be adjusted together, and the overall operation is more convenient.

[0058] A control method for dust removal of a photovoltaic panel based on the above-mentioned photovoltaic cleaning robot:

[0059] By rotating the adjusting screw 105, at this time the adjusting screw 105 continuously moves out of the inside of the adjusting cylinder 106, so that the adjusting outer shell 101 and the supporting outer shell 104 can drive the corresponding brush rollers 202 and the dust suction frames 301 to move synchronously;

[0060] After the adjustment housing 101 and the support housing 104 are adjusted according to the length of the photovoltaic panel, the two socket frames 4 are sleeved on the guide rails installed on both sides of the photovoltaic panel. At this time, a plurality of rotating rollers 501 arranged inside the socket frame 4 are in contact with the top and bottom of the guide rail.

[0061] By driving the motor 504, the motor 504 drives all the rotating rollers 501 to rotate through the sprockets 502 and the chain 503. Under the rotation of the rotating rollers 501, the adjustment housing 101 and the support housing 104 can move on the photovoltaic panel. At the same time, under the linkage of the driving gear 601, the driven gear 602 and the rotating shaft 201, the rotating rollers 501 can drive the brush roller 202 to rotate while the photovoltaic panel is moving.

[0062] The exhaust fan 307 can extract the air inside the adsorption box 306, so that the adsorption box 306 extracts the impurities and dust cleaned by the brush roller 202 through the extraction pipe 303, the branch pipe 304 and the dust suction hood 302. The extracted dust accumulates inside the collection box 310.

[0063] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
