Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cleaning robots, in particular to a quick-detachable cleaning structure and a photovoltaic robot. Background Art

[0002] At present, the sustainable development and environmental protection of solar power generation make it one of the most ideal renewable energy technologies, among which photovoltaic power generation is the main one. Photovoltaic power generation, as an environmentally friendly, green and pollution-free renewable energy, uses sunlight to convert into electrical energy. It has the advantages of full cleanliness, absolute safety, relative extensiveness, real long life and maintenance-free, sufficient resources and potential economy, and plays an important role in the long-term energy strategy. In recent years, the photovoltaic industry has developed vigorously, and a large number of photovoltaic power stations have sprung up.

[0003] During the cleaning process of the photovoltaic cleaning robot, its cleaning components will inevitably encounter problems such as wear and aging after long-term use. Currently, it takes a lot of time to replace the cleaning components on the robot, and it is inconvenient for staff to disassemble it, resulting in low overall replacement efficiency of the cleaning components.

[0004] Therefore, it is necessary to provide a quick-detachable cleaning structure and a photovoltaic robot to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the utility model and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the utility model. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a quick-detachable cleaning structure and a photovoltaic robot, which are convenient for workers to quickly disassemble, maintain or replace cleaning components, reduce time costs and improve disassembly efficiency.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is: a quick-detachable cleaning structure, including a cleaning component, a connecting piece and a moving component; the connecting piece is provided with a fixed end and a disassembly end, the fixed end is connected to the cleaning component, and the disassembly end is detachably connected to the moving component. When the cleaning component is not working, the disassembly end on the connecting piece can enable the cleaning component to be quickly separated from the moving component, which can facilitate the rapid maintenance of the cleaning component on the one hand, and can facilitate the staff to carry the cleaning component and the moving component separately on the other hand. When cleaning is needed, the cleaning component and the moving component can also be quickly assembled without affecting subsequent use.

[0008] Furthermore, the cleaning assembly includes a cleaning roller brush and a connecting bracket supporting the cleaning roller brush, the moving assembly includes a frame shell, and the connecting piece connects the connecting bracket and the frame shell. Both ends of the cleaning roller brush in the length direction are rotatably connected to the connecting bracket, so that the cleaning roller brush can roll to clean the photovoltaic panel surface, and the setting of the connecting bracket facilitates the assembly connection between the cleaning roller brush and the frame shell.

[0009] Furthermore, a support member 2 is respectively arranged on both sides of the frame shell in the length direction, and the disassembly end is detachably connected to the support member 2. The support member 2 is specifically arranged on one end of the frame shell close to the cleaning component, so as to facilitate the connection of the cleaning component with the moving component.

[0010] Furthermore, the disassembly end is provided with a half-open arc groove along its edge, and the second support member is horizontally inserted into the arc groove. The arc groove is provided along the thickness direction of the connecting member, and the arc structure of the arc groove not only adapts to the shape of the second support member, but also enables the connecting member to rotate around the second support member.

[0011] Furthermore, the fixed end is provided with a buckle groove opening toward the direction of the cleaning assembly, and the side of the connecting bracket away from the cleaning roller brush is connected to the buckle groove. The buckle groove is provided to meet the connection and installation of the cleaning assembly and the connecting piece.

[0012] Furthermore, a support member 1 is also arranged on the side of the frame shell, and a guide groove for inserting the support member 1 is arranged on the connecting member, and the guide groove is arranged along the edge of the connecting member and is semi-open.

[0013] The setting position of the support member 1 on the frame shell is higher than the setting position of the support member 2 on the frame shell. The setting of the support member 1 can further support the connecting member, ensure the stability of the connecting bracket during the movement of the moving component, and further ensure the cleaning efficiency of the cleaning roller brush.

[0014] Furthermore, the support member 1 and the support member 2 have the same structure, and the support member 1 includes a fixed shaft threadedly connected to the side of the frame shell, and a fixing screw is locked on the end of the fixed shaft away from the frame shell, and a rotating bearing is sleeved on the outside of the fixed shaft. The fixing screw can provide a limit for the position movement of the rotating sleeve, effectively preventing the rotating sleeve from separating from the fixed shaft. The rotating sleeves are arranged on the support member 1 and the support member 2 so that the connecting member will not generate interference or resistance during the rotation process.

[0015] The setting of the limiting bolt and the limiting nut limits the pressing force of the buffer spring, so that when the buffer spring is in a relaxed state, the surface of the cleaning roller brush fits the flat surface of the photovoltaic panel, thereby cleaning the flat surface.

[0016] While being able to clean the concave parts of the photovoltaic panel surface, it will not affect the quick disassembly of the connector and the moving component. During disassembly, it is only necessary to unscrew the limit nut to separate the connecting plate and the supporting part.

[0017] A photovoltaic robot comprises any quick-detachable cleaning structure described in the above schemes.

[0018] Beneficial effects of the utility model:

[0019] In the utility model, the disassembly end on the connecting piece can make the cleaning component quickly separated from the moving component. On the one hand, it can facilitate the rapid maintenance and care of the cleaning component. On the other hand, it can be convenient for the staff to carry the cleaning component and the moving component separately. When cleaning is needed, the cleaning component and the moving component can also be quickly assembled without affecting the subsequent use, effectively reducing the time cost and improving the disassembly efficiency.

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0026] See attached Figures 1 to 4As shown, a quick-detachable cleaning structure in this embodiment includes a cleaning component 1, a connecting member 2 and a moving component 3; the connecting member 2 is provided with a fixed end 21 and a disassembly end 24, the fixed end 21 is connected to the cleaning component 1, and the disassembly end 24 is detachably connected to the moving component 3. When the cleaning component 1 is not working, the disassembly end 24 on the connecting member 2 can enable the cleaning component 1 to be quickly separated from the moving component 3, which can facilitate the rapid maintenance of the cleaning component 1 on the one hand, and can facilitate the staff to carry the cleaning component 1 and the moving component 3 separately on the other hand. When cleaning is needed, the cleaning component 1 and the moving component 3 can also be quickly assembled without affecting subsequent use.

[0027] The cleaning assembly 1 includes a cleaning roller brush 11 and a connecting bracket 12 supporting the cleaning roller brush 11, the moving assembly 3 includes a frame housing 31, and the connecting member 2 connects the connecting bracket 12 and the frame housing 31. Both ends of the cleaning roller brush 11 in the length direction are rotatably connected to the connecting bracket 12, so that the cleaning roller brush 11 can roll to clean the photovoltaic panel surface, and the connection bracket 12 is provided to facilitate the assembly connection between the cleaning roller brush 11 and the frame housing 31.

[0028] A support member 2 6 is respectively disposed on both sides of the frame housing 31 in the length direction, and the disassembly end 24 is detachably connected to the support member 2 6. The support member 2 6 is specifically disposed on one end of the frame housing 31 close to the cleaning component 1, so as to facilitate the connection between the cleaning component 1 and the moving component 3.

[0029] On the one hand, the support member 6 can support the connecting member 2 connecting the cleaning component 1 and the moving component 3, and on the other hand, it can also realize the detachability of the connecting member 2 and the moving component 3, so that the cleaning component 1 as a whole can be quickly separated from the moving component 3, which not only facilitates the disassembly and maintenance of the cleaning roller brush 11, but also facilitates the handling and transportation of the photovoltaic robot as a whole. The overall structure of the photovoltaic robot is large and heavy. The quick-disassembly structure can effectively reduce transportation costs and labor of staff and improve transportation efficiency.

[0030] The disassembly end 24 is provided with a half-open arc groove 25 along its edge, and the support member 2 6 is horizontally inserted into the arc groove 25. The arc groove 25 is provided along the thickness direction of the connecting member 2, and the arc structure of the arc groove 25 not only adapts to the shape of the support member 2 6, but also enables the connecting member 2 to rotate around the support member 2 6.

[0031] It should be noted that, since the connecting member 2 can rotate around the supporting member 2 6, the cleaning component 1 as a whole can swing up and down around the supporting member 2 6 within the arc range of the arc groove 25, so that the photovoltaic panel surface that can be cleaned is not limited to a horizontal plane. When a depression appears on the photovoltaic panel surface, the cleaning component 1 swings downward around the moving component 3 so that the cleaning roller brush 11 thereon is located in the depression, thereby cleaning the depressed surface.

[0032] In some embodiments, two connecting members 2 are vertically arranged, and the disassembly ends 24 thereon are detachably connected to the two side edges of the frame shell 31 in the length direction. By providing two connecting members 2, the stability of the cleaning component 1 when cleaning the photovoltaic panel surface can be ensured, and the cleaning roller brush 11 will not be tilted, thereby ensuring the cleaning efficiency of the photovoltaic panel surface.

[0033] The fixed end 21 is provided with a buckle slot 211 opening toward the cleaning component 1, and the side of the connecting bracket 12 away from the cleaning roller brush 11 is connected to the buckle slot 211. The buckle slot 211 is provided to meet the connection and installation of the cleaning component 1 and the connecting member 2.

[0034] In some embodiments, the snap groove 211 includes a horizontal inner wall and a vertical inner wall. The snap groove 211 can semi-cover the connecting bracket 12, and the connecting bracket 12 is completely located in the snap groove 211. The upper and lower ends of the snap groove 211 are respectively bent to form a hook 212, and the two hooks 212 respectively hook the upper and lower ends of the connecting bracket 12. At this time, the vertical inner wall on the snap groove 211 is completely fitted with the side of the connecting bracket 12 away from the cleaning roller brush 11, ensuring that the cleaning component 1 and the connecting member 2 are installed in place, and ensuring the stability of the subsequent cleaning roller brush 11 during the cleaning process.

[0035] In other embodiments, the snap groove 211 includes a horizontal inner wall and a vertical inner wall. The upper and lower horizontal inner walls of the snap groove 211 are connected to the connecting bracket 12 by screw locking. A threaded groove 213 is provided on the two horizontal inner walls. As long as it can be ensured that during the cleaning process of the cleaning roller brush 11, there will be no relative movement between the connecting bracket 12 and the connecting end, thereby ensuring the cleaning stability of the cleaning roller brush 11, and preventing the position of the cleaning roller brush 11 from being offset, or the cleaning component 1 and the moving component 3 from falling off, thereby avoiding affecting the cleaning effect.

[0036] A support member 5 is also provided on the side of the frame shell 31, and a guide groove 23 for inserting the support member 5 is provided on the connecting member 2. The guide groove 23 is provided along the edge of the connecting member 2 and is semi-open.

[0037] The setting position of the support member 1 5 on the frame shell 31 is higher than the setting position of the support member 2 6 on the frame shell 31. The setting of the support member 1 5 can further support the connecting member 2, ensure the stability of the connecting bracket 12 during the movement of the moving component 3, and further ensure the cleaning efficiency of the cleaning roller brush 11.

[0038] The guide groove 23 is tilted toward the direction close to the moving component 3, so that it will not interfere with the upward tilting and lifting of the end of the cleaning component 1, and can also meet the cleaning of the concave part of the photovoltaic panel surface, that is, its tilting direction is adapted to the swinging direction of the cleaning component 1. Among them, the end of the guide groove 23 close to the cleaning component 1 extends out of the connecting member 2, and when the cleaning component 1 is lifted, the connecting member 2 can be driven to lift up as a whole and separate from the support member 1 5 and the support member 2 6 on the moving component 3, so as to realize the quick release between the cleaning component 1 and the moving component 3.

[0039] The connecting member 2 is provided with a plurality of weight-avoiding grooves 22 to reduce the weight when the moving component 3 drives the cleaning component 1 to move.

[0040] The support member 1 5 has the same structure as the support member 2 6. The support member 1 5 includes a fixed shaft 51 threadedly connected to the side of the frame shell 31. A fixing screw 52 is locked on the end of the fixed shaft 51 away from the frame shell 31, and a rotating bearing is sleeved on the outside of the fixed shaft 51. The fixing screw 52 can provide a limit for the position movement of the rotating shaft sleeve 53, effectively preventing the rotating shaft sleeve 53 from separating from the fixed shaft 51. The rotating shaft sleeve 53 is arranged on the support member 1 5 and the support member 2 6 so that the connecting member 2 will not generate interference or resistance during the rotation process.

[0041] In some embodiments, the connector 2 is further provided with a buffer assembly 4, which includes an adjustment shaft 42, one end of which passes through the connector 2 and is connected to the support member 1 5 located in the guide groove 23, and the other end extends out of the connector 2. The portion of the adjustment shaft 42 located in the guide groove 23 and the connector 2 is sleeved with a buffer spring 41, and the connector 2 is provided with a limit groove 45 for the adjustment shaft 42 to be inserted. The end of the adjustment shaft 42 away from the support member 1 5 is sleeved with a limit bolt 43, the base end of the limit bolt 43 is located in the limit groove 45, and the screw end thereof is connected with a limit nut 44. When the concave surface on the photovoltaic panel is to be cleaned, the cleaning assembly 1 swings downward with the support member 2 6 as the fulcrum, and the buffer spring 41 is in a compressed state at the same time, and can buffer the downward swing of the cleaning assembly 1 when entering the concave surface, thereby increasing the service life of the cleaning roller brush 11. When the cleaning of the concave surface is completed, the elastic force of the buffer spring 41 itself can assist the cleaning assembly 1 to return to the plane. The roller brush is adaptively adjusted.

[0042] The setting of the limiting bolt 43 and the limiting nut 44 limits the pressing force of the buffer spring 41, so that when the buffer spring 41 is in a relaxed state, the surface of the cleaning roller brush 11 fits with the flat surface of the photovoltaic panel to achieve cleaning of the flat surface.

[0043] While being able to clean the concave part of the photovoltaic panel surface, it will not affect the quick disassembly of the connecting member 2 and the moving component 3. During disassembly, it is only necessary to unscrew the limiting nut 44 to separate the connecting plate and the supporting member 5.

[0044] A photovoltaic robot comprises any quick-detachable cleaning structure described in the above schemes.

[0045] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
