[0002] During the long-term use of solar street lights, the surface of the photovoltaic panels will inevitably be affected by some stains, mainly including the adhesion of dust in the air. If these stains are not cleaned in time, they will gradually accumulate and affect the light transmittance of the photovoltaic panels, reducing the photoelectric conversion efficiency. In severe cases, this impact will lead to a hot spot effect, affecting the normal operation of the entire solar street light.

The aluminum alloy profile 101 is hinged at the end of the arm 300, and the bearing seat 102 is fixedly mounted on the aluminum alloy profile. At the middle position of the bottom of 101, the mounting plate 103 is hinged to the bottom of the bearing seat 102, the wool cylinder 104 is arranged parallel to the bottom of the mounting plate 103, the connecting plate 105 is fixedly installed at both ends of the aluminum alloy profile 101, the slide rod 106 is respectively slidably arranged on the two connecting plates 105 away from one side, the sheet metal wheel frame 107 is fixedly set at the bottom of the slide rod 106, the chain 1011 is fixedly set between the two sheet metal wheel frames 107, the bearing seat 2 109 is fixedly installed at both ends of the bottom of the aluminum alloy profile 101, and is located between the two connecting plates 105, and the sprocket 2 1010 rotates The chain 1011 is connected to the outer periphery of the top of the sprocket 1010, and the sprocket 1012 is rotatably mounted on the inside of the bearing seat 102. The chain 1011 is connected to the outer periphery of the top of the sprocket 1012. The shaft 1014 is fixedly mounted on the inner wall of the sprocket 1012 and is rotatably mounted on the inside of the bearing seat 102 and passes through the bearing seat 102. The fixing blocks 1015 are fixedly mounted on both ends of the outer wall of the shaft 1014. The mounting blocks 1016 are respectively fixedly mounted on the bottom of the two fixing blocks 1015, and the two mounting blocks 101 The bottom of the sheet metal wheel frame 107 and the top of the mounting plate 103 are fixedly connected by a plurality of connecting rods. The spring 108 is sleeved on the periphery of the slide bar 106. The linear bearings 1013 are respectively fixedly mounted on the side away from the two connecting plates 105, and two parallel connecting plates 105 are fixedly mounted on each connecting plate 105. The spring 108 is fixedly mounted between the bottom of the sheet metal wheel frame 107 and the linear bearing 1013. The positioning shaft pin 1017 is fixedly mounted on the side away from the two sheet metal wheel frames 107. The rubber wheel 1018 is rotatably mounted on the outer wall of the two positioning shaft pins 1017.

[0057] Specifically, the cleaning assembly 100 is driven by the crawler 200 to move to the photovoltaic panel area that needs to be cleaned, and the output end of the crawler 200 drives the arm 300 to rotate up and down to adjust the overall height of the cleaning assembly 100, and then the angle of the cleaning assembly 100 is adjusted according to the installation inclination angle of the photovoltaic panel. Specifically, the crawler 200 controls the oil cylinder 400 to extend or retract its output rod, thereby driving the lifting ear 1019 to rotate along the hinge with the arm 300 to achieve the overall angle adjustment of the cleaning assembly 100, so that the bottom of the wool tube 104 can be in full contact with the top of the photovoltaic panel, thereby Adapting to the cleaning needs of photovoltaic panels with different inclination settings, due to the factors of photovoltaic panel installation and processing errors, it is difficult to ensure that each photovoltaic panel is completely parallel after splicing and installation. In other words, there is actually a certain amount of deviation in the inclination of each photovoltaic panel. Therefore, it is difficult to ensure that the bottom of the wool cylinder 104 is in full contact with each photovoltaic panel by only adjusting the overall angle of the cleaning component 100 through the output rod of the oil cylinder 400. This can easily lead to omissions in the cleaning of the photovoltaic panel, resulting in incomplete cleaning. Therefore, in this device, when the bottoms of the two wool cylinders 104 are in contact with the photovoltaic panel, When the top contacts, the bottoms of the two rubber wheels 1018 just contact the tops of the edges at both ends of the photovoltaic panel, and roll along the edges of the top of the photovoltaic panel as the cleaning component 100 moves. When the spring 108 rolls to another photovoltaic panel, if the inclination angle of the photovoltaic panel deviates, the side of the photovoltaic panel that deviates upward will squeeze the rubber wheel 1018 upward, and the rubber wheel 1018 and the corresponding set of sheet metal wheel frames 107 and slide rods 106 slide upward along the inner wall of the linear bearing 1013, compressing the spring 108 located outside the slide rod 106 to continue to store force, while the remaining rebound force of the other spring 108 is released. Push another sheet metal wheel frame 107 and another rubber wheel 1018 downward until the bottoms of the two rubber wheels 1018 are in contact with the top of the photovoltaic panel. During this period, chain one 1011 drives sprocket two 1012 to rotate under the rolling support of the two sprocket two 1010, and the rotation of sprocket two 1012 drives the two fixed blocks 1015 to rotate together through the shaft 1014. At the same time, the rotation of the fixed block 1015 drives the mounting plate 103 together with the wool tube 104 through the connection of the mounting block 1016 and the connecting rod, so that the bottom of the wool tube 104 is in full contact with the top of the photovoltaic panel.

[0058] For further details, please refer to Figure 6 、 Figure 7 and Figure 8 As shown:

[0059] A power assembly is fixedly installed on the top of the mounting plate 103;

[0060] The power assembly includes a reduction motor 501, a transmission shaft 502, a sprocket three 503, a cleaning shaft 504, a sprocket four 505 and a chain two 509. The reduction motor 501 is fixedly mounted on the top of the mounting plate 103. The transmission shaft 502 is fixedly mounted on the end of the output shaft of the reduction motor 501 through a coupling. The sprocket three 503 is fixedly mounted on the outer wall of the transmission shaft 502 away from the end of the reduction motor 501. The cleaning shaft 504 is fixedly mounted inside the two wool cylinders 104 respectively. The sprocket four 505 is fixedly mounted on the outer wall of the two cleaning shafts 504 near the sprocket three 503. At one end, chain two 509 is wrapped around the periphery of sprocket three 503 and two sprocket fours 505, and two bearing seats three 5010 are fixedly installed at both ends of the bottom of the mounting plate 103. The positions of the two bearing seats three 5010 correspond one-to-one to the positions of the two cleaning shafts 504. The cleaning shaft 504 is rotatably installed inside the corresponding bearing seat three 5010 through bearings. A bearing seat four 5011 is fixedly installed on the top of the mounting plate 103. The position of the bearing seat four 5011 corresponds to the position of the transmission shaft 502, and the transmission shaft 502 is rotatably installed inside the bearing seat four 5011 through bearings.

[0061] Specifically, the output shaft of the reduction motor 501 drives the transmission shaft 502 and the sprocket three 503 to rotate, and further, under the connection of the chain two 509, drives the two sprocket four 505 and the two cleaning shafts 504 to rotate together. The rotation of the two cleaning shafts 504 drives the two wool cylinders 104 to rotate together, and the dust on the top of the photovoltaic panel is cleaned by the two rotating wool cylinders 104.

[0062] For further details, please refer to Figure 8 As shown:

[0063] A mounting groove 1003 is provided at the top of the mounting plate 103 near one end of the chain 2 509, and a tensioning plate 506 is fixedly installed inside the mounting groove 1003 by bolts. Two waist grooves for tensioning and adjusting the chain 2 509 are provided on the surface of the tensioning plate 506, and the tensioning plate 506 is fixedly connected between the waist groove and the mounting groove 1003 by bolts passing through the waist groove. A tensioning shaft 507 is rotatably installed inside the tensioning plate 506 through a bearing, and a tensioning sprocket 508 is fixedly installed on the outer wall of the tensioning shaft 507 near one end of the chain 2 509, and the chain 2 509 is wrapped around the periphery of the tensioning sprocket 508.

[0064] Specifically, a tensioning plate 506, a tensioning shaft 507 and a tensioning sprocket 508 are provided to support chain 2 509 to prevent contact interference between chain 2 509 and chain 1 1011. At the same time, since a waist groove is provided on the surface of the tensioning plate 506, the position of the tensioning plate 506 can be adjusted up and down through the waist groove, thereby driving the tensioning shaft 507 and the tensioning sprocket 508 to be adjusted together to achieve the tensioning effect of chain 2 509, so as to ensure that chain 2 509 has good transmission efficiency.

[0065] For further details, please refer to Figure 1 、 Figure 2 As shown:

[0066] The boom 300 is fixedly connected to the output end of the crawler vehicle 200, and a lifting ear 1019 is fixedly installed in the middle of the side of the aluminum alloy profile 101 away from the mounting plate 103. The end of the boom 300 away from the crawler vehicle 200 is hinged to the lifting ear 1019, and the top of the boom 300 is hinged with a cylinder 400, and the output rod end of the cylinder 400 is hinged to the lifting ear 1019. Protective covers 600 are fixedly installed on both sides of the bottom of the mounting plate 103.

[0067] Specifically, the cleaning assembly 100 is driven by the crawler vehicle 200 to move to the photovoltaic panel area that needs to be cleaned, and the output end of the crawler vehicle 200 drives the arm 300 to rotate up and down to adjust the overall height of the cleaning assembly 100, and then the angle of the cleaning assembly 100 is adjusted according to the installation inclination angle of the photovoltaic panel. Specifically, the crawler vehicle 200 controls the cylinder 400 to extend or retract its output rod, thereby driving the lifting ear 1019 to rotate along the hinge with the arm 300 to achieve the overall angle adjustment of the cleaning assembly 100, so that the bottom of the wool tube 104 can be fully in contact with the top of the photovoltaic panel, thereby adapting to the cleaning needs of photovoltaic panels with different inclination settings. Then, people drive the crawler vehicle 200 to move, driving the cleaning assembly 100 to move along the top of the photovoltaic panel for cleaning.

[0068] In this scheme, an adjustable cleaning device for photovoltaic panels is used. When the cleaning assembly 100 is in operation, the crawler 200 drives the cleaning assembly 100 to move to the photovoltaic panel area that needs to be cleaned, and the output end of the crawler 200 drives the arm 300 to rotate up and down to adjust the overall height of the cleaning assembly 100. Then, the angle of the cleaning assembly 100 is adjusted according to the installation inclination angle of the photovoltaic panel. Specifically, the crawler 200 controls the oil cylinder 400 to extend or retract its output rod, thereby driving the lifting lug 1019 to rotate along the hinge with the arm 300 to achieve the overall angle adjustment of the cleaning assembly 100, so that the wool tube 1 The bottom of 04 can be in full contact with the top of the photovoltaic panel, so as to adapt to the cleaning needs of photovoltaic panels with different inclination settings. Then, people drive the crawler 200 to move, driving the cleaning component 100 to move along the top of the photovoltaic panel. At the same time, the output shaft of the reduction motor 501 drives the transmission shaft 502 and the sprocket three 503 to rotate, and further drives the two sprocket four 505 and the two cleaning shafts 504 to rotate together under the connection of the chain two 509. The rotation of the two cleaning shafts 504 drives the two wool cylinders 104 to rotate together, and the dust on the top of the photovoltaic panel is cleaned by the two rotating wool cylinders 104;

[0069] Due to the factors of photovoltaic panel installation and processing errors, it is difficult to ensure that each photovoltaic panel is completely parallel after splicing and installation. In other words, there is actually a certain deviation in the inclination angle of each photovoltaic panel. Therefore, it is difficult to ensure that the bottom of the wool cylinder 104 is in complete contact with each photovoltaic panel by only adjusting the overall angle of the cleaning component 100 through the output rod of the oil cylinder 400. This can easily lead to omissions in the cleaning of the photovoltaic panels, resulting in incomplete cleaning. Therefore, in this device, when the bottoms of the two wool cylinders 104 are in contact with the top of the photovoltaic panel, the bottoms of the two rubber wheels 1018 just contact the top of the edges at both ends of the photovoltaic panel, and roll along the edges on both sides of the top of the photovoltaic panel as the cleaning component 100 moves. When the spring 108 rolls to another photovoltaic panel, if the inclination angle of the photovoltaic panel deviates, the side of the photovoltaic panel that deviates upward will push the rubber wheel 1018 When squeezed upward, the rubber wheel 1018 and the corresponding set of sheet metal wheel frames 107 and slide rod 106 slide upward along the inner wall of the linear bearing 1013, compressing the spring 108 located on the periphery of the slide rod 106 to continue to store force, and the remaining rebound force of the other spring 108 is released to push the other sheet metal wheel frame 107 and the other rubber wheel 1018 to move downward until the bottoms of the two rubber wheels 1018 are in contact with the top of the photovoltaic panel. During this period, the chain 1011 drives the sprocket 2 1012 to rotate under the rolling support of the two sprockets 1010, and the rotation of the sprocket 2 1012 drives the two fixed blocks 1015 to rotate together through the shaft 1014. At the same time, the rotation of the fixed block 1015 drives the mounting plate 103 together with the wool tube 104 through the connection of the mounting block 1016 and the connecting rod, so that the bottom of the wool tube 104 is in full contact with the top of the photovoltaic panel.

[0070] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
