Description

Technical Field

[0001] The invention relates to the technical field of cleaning manipulators, in particular to a rotary cleaning manipulator for desert photovoltaics. Background Art

[0002] As the photovoltaic industry continues to grow, the photovoltaic panel cleaning industry is also developing. In the early days, the photovoltaic panel cleaning industry mainly used manual cleaning methods, which had low cleaning efficiency and were very expensive, greatly increasing the operation and maintenance costs of photovoltaic power stations. Now, the photovoltaic panel cleaning market has developed photovoltaic panel cleaning vehicles and intelligent photovoltaic panel cleaning robots. Intelligent photovoltaic panel cleaning robots are usually fixed on one or several rows of photovoltaic panels, and they travel back and forth between photovoltaic panels via tracks. However, they have high requirements for the basic construction environment of photovoltaic power stations, cannot be widely promoted, and have high operation and maintenance costs and high maintenance frequency.

[0003] During the cleaning process of the photovoltaic panels, if the equipment encounters wind, uneven photovoltaic panel surface, or vibration caused by its own movement, it may slide on the photovoltaic panels or be blown off the predetermined cleaning path. This position deviation will result in an incomplete cleaning area, and some areas may be cleaned repeatedly or other areas may be missed. Some photovoltaic panel areas cannot be effectively cleaned, reducing cleaning efficiency. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A rotary cleaning manipulator for desert photovoltaics, comprising a cart, the top of the cart is fixedly connected to a base, and the top of the base is fixedly connected to a mechanical arm;

[0005] A frame body, the frame body is fixedly connected to an end of the mechanical arm away from the base, and the inner wall of the frame body is rotatably connected with a connecting piece;

[0006] A limit assembly is fixedly mounted on the bottom of the frame. There are two limit assemblies, which are symmetrically arranged at both ends of the frame.

[0007] A cleaning assembly, the cleaning assembly is rotatably connected to the inner side of the frame, the cleaning assembly is located in the middle of the frame, and the cleaning assembly is rotatably connected to the connecting piece;

[0008] A protection component is fixedly mounted on the side of the frame, and the protection component is symmetrically arranged with the cleaning component as the center;

[0009] Among them, the limiting component includes a fixed block. A limiting groove is formed at the top of the fixed block. The fixed block is slidably connected to the frame through the limiting groove. A return spring is fixedly connected inside the limiting groove. One end of the return spring away from the limiting groove is fixedly connected to the bottom of the frame. An intermediate plate is fixedly connected to the side of the fixed block. Place the frame above the photovoltaic panel. The fixed block contacts and presses against the frame of the photovoltaic panel. The fixed block slides on the frame along the direction of the limiting groove under the force, so that the fixed block drives the roller away from the frame of the photovoltaic panel. The frame continues to move downward. Under the elastic force of the return spring, the fixed block resets, so that the roller is located inside the frame of the photovoltaic panel. At this time, the roller is slidably connected to the inner wall of the frame of the photovoltaic panel. By clamping with the frame of the photovoltaic panel through the limiting component, it can be easily combined with the frame of the photovoltaic panel without complex tools or cumbersome installation steps, which can greatly shorten the installation time and improve the efficiency of the cleaning work. At the same time, the return spring will automatically adjust the fitting degree according to the shape and size of the frame, effectively preventing scratches on the surface and frame of the photovoltaic panel. Rollers are rotatably connected to both ends of the intermediate plate. An inclined block is fixedly connected to the side of the fixed block close to the intermediate plate. The trolley drives the frame to move, so that the frame drives the cleaning component and the limiting component to move on the photovoltaic panel. The inclined block moves inside the frame of the photovoltaic panel to clean the sand grains inside the photovoltaic panel, avoiding the situation where the roller gets stuck during the cleaning process. The cleaned sand grains move along the hypotenuse of the inclined block and then leave the inclined block from the arc plate to prevent accumulation. An arc plate is fixedly connected to the hypotenuse of the inclined block. A brush is fixedly connected to the side of the inclined block close to the roller.

[0010] Preferably, extension plates are fixedly connected to the side of the fixed block close to the limiting groove. The number of extension plates is two. The two extension plates are symmetrically arranged with the fixed block as the center. Extension rods are fixedly connected to the ends of the extension plates away from the fixed block. By setting the extension rods and extension plates, a guiding and limiting function is achieved to prevent the fixed block from moving away from the frame. The two ends of the extension rod are fixedly connected to the two extension plates. The side of the arc plate away from the inclined block is fixedly connected to the fixed block.

[0011] Preferably, the frame body includes a housing, the top of the housing is fixedly connected to the robotic arm, the housing is configured as a gantry, a chute is opened at the bottom side of the housing, the extension rod is located inside the through hole, and the extension rod is slidably connected to the through hole. The fixed block and the housing are slidably adapted through the chute and the limiting groove. An annular groove is opened inside the housing, and the annular groove is slidably connected to the protection assembly. A rotating rod is rotatably connected inside the housing. A runner is fixedly connected to the outer side of the rotating rod close to the housing. By providing runners at both ends of the cleaning assembly, the frame body can move linearly on the photovoltaic panel, preventing the cleaning assembly from tilting or shifting on the photovoltaic panel. And in a windy environment, the cleaning assembly can still move smoothly on the photovoltaic panel and perform cleaning work without losing balance due to the influence of wind. The rotating rod is rotatably connected to the connecting piece, and the rotating rod is rotatably connected to the cleaning assembly through the connecting piece. A convex strip is fixedly connected to the middle of the outer side of the rotating rod. A through hole is opened on the outer side of the housing close to the chute, the through hole penetrates the housing with the chute, a through groove is opened at the edge of the through hole, and a round rod is fixedly connected to the inner wall of the housing close to the protection assembly.

[0012] Preferably, the cleaning assembly includes a rotating shaft, the rotating shaft is rotatably connected to the middle of the inside of the housing, the rotating shaft is rotatably connected to the connecting piece, a rotating cylinder is fixedly connected to the middle of the outer side of the rotating shaft. The trolley moves along the photovoltaic panel, driving the runner to roll on the photovoltaic panel. The runner drives the rotating shaft to rotate through the connecting piece, and the rotating shaft drives the rotating cylinder and the cleaning brush to rotate. The cleaning brush cleans the surface of the photovoltaic panel. By arranging the cleaning brushes symmetrically in a spiral shape, during the rotation or movement of the spiral cleaning brushes, sand grains and other stains can be swept up from the surface of the photovoltaic panel. At this time, the diversion groove and the spiral plate can timely collect the sand grains swept up by the cleaning brush, so that the sand grains will not spread again on the surface of the photovoltaic panel, thereby shortening the cleaning time and improving the cleaning efficiency. This can prevent a thick accumulation layer of sand grains from forming on the surface of the photovoltaic panel, because the accumulated sand grains will affect the light transmittance of the photovoltaic panel, thereby reducing the photovoltaic power generation efficiency. A rotating plate is fixedly connected to the middle of the outer side of the rotating cylinder. The number of rotating plates is multiple, and the multiple rotating plates are evenly distributed around the rotating cylinder. Cleaning brushes are fixedly connected to the outer side of the rotating cylinder. A diversion groove is opened on the outer side of the rotating cylinder, a spiral plate is fixedly connected to the inside of the diversion groove, the spiral plate is provided with a protective edge, the spiral plate and the cleaning brush are alternately arranged on the outer side of the rotating cylinder. The number of spiral plates is two, and the two spiral plates are symmetrically arranged with the rotating plate as the center.

[0013] Preferably, the protection component includes a square plate. A sliding rod is fixedly connected to the side of the square plate. The sliding rod is slidably connected to the annular groove, and both ends of the sliding rod are located inside the annular groove. One end of the square plate away from the sliding rod is fixedly connected to a connecting plate. A square groove is formed at the bottom of the connecting plate. The rotating wheel drives the rotating rod to rotate, so that the rotating rod drives the outer convex strip to rotate. At this time, extrusion occurs between the convex strip and the outer convex block, causing the convex strip to drive the convex block to move downward. At this time, the convex block drives the square plate and the sliding rod to move through the inclined plate. At this time, the sliding rod moves downward inside the annular groove, further compressing the spring and deforming it. The round rod slides inside the square groove at the bottom of the connecting plate, so that the positioning groove on the side of the connecting plate approaches the cleaning component and contacts the outer bristles of the cleaning brush. After the bristles contact the positioning groove, they disperse, thereby achieving the cleaning of the bristles, preventing sand grains from getting stuck between the bristles. The sand grains fall along the connecting plate to the middle of the square plate and the connecting plate, which is convenient for cleaning. The round rod is located inside the square groove. A positioning groove is formed at one end of the connecting plate away from the square plate. The positioning groove contacts the outside of the cleaning brush. A compression spring is fixedly connected to the end of the sliding rod. The end of the compression spring away from the sliding rod is fixedly connected to the inside of the annular groove. An inclined plate is fixedly connected to the outside of the square plate. A convex block is fixedly connected to the side of the inclined plate close to the square plate. The convex block is rotationally adapted to the outside of the convex strip.

[0014] The present invention provides a rotating cleaning type manipulator for desert photovoltaic power generation. It has the following beneficial effects:

[0015] First, for this rotating cleaning type manipulator for desert photovoltaic power generation, by clamping with the photovoltaic panel frame through the limiting component, it can be easily combined with the photovoltaic panel frame without complex tools or cumbersome installation steps, which can greatly shorten the installation time and improve the efficiency of the cleaning work. At the same time, the reset spring will automatically adjust the fitting degree according to the shape and size of the frame, effectively preventing scratches on the surface and frame of the photovoltaic panel.

[0016] Second, for this rotating cleaning type manipulator for desert photovoltaic power generation, by moving the inclined block inside the photovoltaic panel frame, the sand grains inside the photovoltaic panel are cleaned, avoiding the situation where the rollers get stuck during the cleaning process. The cleaned sand grains move along the hypotenuse of the inclined block and then leave the inclined block from the arc plate, preventing accumulation.

[0017] Third, for this rotating cleaning type manipulator for desert photovoltaic power generation, by setting rotating wheels at both ends of the cleaning component, the frame can move linearly on the photovoltaic panel, preventing the cleaning component from tilting or shifting on the photovoltaic panel. And in a windy environment, the cleaning component can still move smoothly on the photovoltaic panel and perform the cleaning work without losing balance due to the influence of wind.

[0018] IV. For the rotating and sweeping manipulator for desert photovoltaic applications, when the spiral cleaning brush rotates or moves, it can sweep sand and other stains from the surface of the photovoltaic panel. At this time, the diversion groove and the spiral plate can timely collect the sand swept by the cleaning brush, preventing the sand from spreading again on the surface of the photovoltaic panel, thus shortening the cleaning time and improving the cleaning efficiency.

[0019] V. For the rotating and sweeping manipulator for desert photovoltaic applications, it approaches the cleaning component through the positioning groove on the side of the connecting plate and contacts the outer bristles of the cleaning brush. After the bristles contact the positioning groove, they disperse, thereby achieving the cleaning of the bristles, preventing sand from getting stuck between the bristles, and the sand falls along the connecting plate into the middle of the square plate and the connecting plate, facilitating cleaning.

[0035] Among them, the limit component 5 includes a fixed block 51. A limit groove 52 is formed at the top of the fixed block 51. The fixed block 51 is slidably connected to the frame body 4 through the limit groove 52. A return spring 55 is fixedly connected inside the limit groove 52. One end of the return spring 55 away from the limit groove 52 is fixedly connected to the bottom of the frame body 4. An intermediate plate 56 is fixedly connected to the side of the fixed block 51. When the frame body 4 is placed above the photovoltaic panel, the fixed block 51 contacts and presses against the frame of the photovoltaic panel. The fixed block 51 slides on the frame body 4 along the direction of the limit groove 52 under the force, so that the fixed block 51 drives the roller 57 away from the frame of the photovoltaic panel. When the frame body 4 continues to move downward, under the elastic force of the return spring 55, the fixed block 51 resets, so that the roller 57 is located inside the frame of the photovoltaic panel. At this time, the roller 57 is slidably connected to the inner wall of the frame of the photovoltaic panel. By clamping with the frame of the photovoltaic panel through the limit component 5, it can be easily combined with the frame of the photovoltaic panel without complex tools or cumbersome installation steps, which can greatly shorten the installation time and improve the efficiency of the cleaning work. At the same time, the return spring 55 will automatically adjust the fitting degree according to the shape and size of the frame, effectively preventing scratches on the surface and frame of the photovoltaic panel. Roller 57 is rotatably connected to both ends of the intermediate plate 56. A slant block 58 is fixedly connected to the side of the fixed block 51 close to the intermediate plate 56.

The slant block 58 moves inside the frame of the photovoltaic panel to clean the sand grains inside the photovoltaic panel, avoiding the situation that the roller 57 gets stuck during the cleaning process. The cleaned sand grains move along the hypotenuse of the slant block 58 and then leave the slant block 58 from the arc plate 510 to prevent accumulation. The hypotenuse of the slant block 58 is fixedly connected to the arc plate 510. A brush 59 is fixedly connected to the side of the slant block 58 close to the roller 57.

[0036] An extension plate 53 is fixedly connected to the side of the fixed block 51 close to the limit groove 52. The number of the extension plates 53 is two. The two extension plates 53 are symmetrically arranged with the fixed block 51 as the center. An extension rod 54 is fixedly connected to the end of the extension plate 53 away from the fixed block 51. By providing the extension rod 54 and the extension plate 53, a guiding and limiting function is achieved to prevent the fixed block 51 from moving away from the frame body 4. Both ends of the extension rod 54 are fixedly connected to the two extension plates 53. The side of the arc plate 510 away from the slant block 58 is fixedly connected to the fixed block 51.

[0037] Second embodiment. On the basis of the first embodiment, please refer to Figures 5 to 7As shown in the figure, the frame body 4 includes a housing 41. The top of the housing 41 is fixedly connected to the robotic arm 3. The housing 41 is configured as a gantry. An inclined groove 42 is formed in the bottom side of the housing 41.

An annular groove 43 is formed inside the housing 41, and the annular groove 43 is slidably connected to the protection assembly 6. A rotating rod 45 is rotatably connected inside the housing 41. A runner 44 is fixedly connected to the rotating rod 45 near the outer side of the housing 41. By arranging the runners 44 at both ends of the cleaning assembly 7, the frame body 4 can move linearly on the photovoltaic panel, preventing the cleaning assembly 7 from tilting or shifting on the photovoltaic panel. And in a windy environment, the cleaning assembly can still move smoothly on the photovoltaic panel and perform the cleaning work without losing balance due to the influence of the wind. The rotating rod 45 is rotatably connected to the connecting member 8, and the rotating rod 45 is rotatably connected to the cleaning assembly 7 through the connecting member 8. A convex strip 46 is fixedly connected to the middle of the outer side of the rotating rod 45. A through hole 48 is formed in the outer side of the housing 41 near the inclined groove 42. The through hole 48 penetrates the housing 41 with the inclined groove 42. A through groove 49 is formed at the edge of the through hole 48. A round rod 47 is fixedly connected to the inner wall of the housing 41 near the protection assembly 6.

[0038] The cleaning assembly 7 includes a rotating shaft 71. The rotating shaft 71 is rotatably connected to the middle of the inside of the housing 41. The rotating shaft 71 is rotatably connected to the connecting member 8. A rotating cylinder 72 is fixedly connected to the middle of the outer side of the rotating shaft 71. The cart moves along the photovoltaic panel, driving the runner 44 to roll on the photovoltaic panel. The runner 44 drives the rotating shaft 71 to rotate through the connecting member 8. The rotating shaft 71 drives the rotating cylinder 72 and the cleaning brush 74 to rotate. The cleaning brush 74 cleans the surface of the photovoltaic panel. By arranging the cleaning brushes 74 symmetrically in a spiral shape, the spiral cleaning brushes 74 can sweep up stains such as sand grains from the surface of the photovoltaic panel during rotation or movement. At this time, the diversion groove 75 and the spiral plate 76 can timely collect the sand grains swept up by the cleaning brush 74, so that the sand grains will not spread again on the surface of the photovoltaic panel, thereby shortening the cleaning time and improving the cleaning efficiency. This can avoid the formation of a thick accumulation layer of sand grains on the surface of the photovoltaic panel, because the accumulated sand grains will affect the light transmittance of the photovoltaic panel and thus reduce the photovoltaic power generation efficiency. A rotating plate 73 is fixedly connected to the middle of the outer side of the rotating cylinder 72. The number of the rotating plates 73 is multiple, and the multiple rotating plates 73 are evenly distributed around the rotating cylinder 72. A cleaning brush 74 is fixedly connected to the outer side of the rotating cylinder 72. A diversion groove 75 is formed in the outer side of the rotating cylinder 72. A spiral plate 76 is fixedly connected to the inside of the diversion groove 75. The spiral plate 76 is provided with a protection edge. The spiral plate 76 and the cleaning brush 74 are alternately arranged on the outer side of the rotating cylinder 72. The number of the spiral plates 76 is two, and the two spiral plates 76 are symmetrically arranged with the rotating plate 73 as the center.

[0039] For the third embodiment, on the basis of the first and second embodiments, please refer to Figure 8As shown, the protection component 6 includes a square plate 61. A sliding rod 62 is fixedly connected to the side of the square plate 61. The sliding rod 62 is slidably connected to the annular groove 43. Both ends of the sliding rod 62 are located inside the annular groove 43. One end of the square plate 61 away from the sliding rod 62 is fixedly connected to a connecting plate 63. A square groove 65 is opened at the bottom of the connecting plate 63. The rotating wheel 44 drives the rotating rod 45 to rotate, so that the rotating rod 45 drives the outer convex strip 46 to rotate. At this time, an extrusion is generated between the convex strip 46 and the outer convex block 68, so that the convex strip 46 drives the convex block 68 to move downward. At this time, the convex block 68 drives the square plate 61 and the sliding rod 62 to move through the inclined plate 67. At this time, the sliding rod 62 moves downward inside the annular groove 43, and then the compression spring 66 is deformed under force, so that the round rod 47 slides inside the square groove 65 at the bottom of the connecting plate 63. Thus, the positioning groove 64 on the side of the connecting plate 63 approaches the cleaning component 7 and contacts the outer bristles of the cleaning brush 74. After the bristles contact the positioning groove 64, they are dispersed, so as to clean the bristles, prevent sand grains from getting stuck between the bristles, and the sand grains fall along the connecting plate 63 to the middle of the square plate 61 and the connecting plate 63, which is convenient for cleaning. The round rod 47 is located inside the square groove 65. A positioning groove 64 is opened at one end of the connecting plate 63 away from the square plate 61. The positioning groove 64 contacts the outside of the cleaning brush 74. The end of the sliding rod 62 is fixedly connected to a compression spring 66. The end of the compression spring 66 away from the sliding rod 62 is fixedly connected to the inside of the annular groove 43. An inclined plate 67 is fixedly connected to the outside of the square plate 61. A convex block 68 is fixedly connected to the side of the inclined plate 67 close to the square plate 61. The convex block 68 is rotationally adapted to the outside of the convex strip 46.

[0040] During use, place the frame body 4 above the photovoltaic panel. The fixing block 51 contacts and is extruded by the frame of the photovoltaic panel. The fixing block 51 slides on the frame body 4 along the direction of the limiting groove 52 under force, so that the fixing block 51 drives the roller 57 away from the frame of the photovoltaic panel. The frame body 4 continues to move downward. Under the elastic force of the reset spring 55, the fixing block 51 resets, so that the roller 57 is located inside the frame of the photovoltaic panel. At this time, the roller 57 is slidably connected to the inner wall of the frame of the photovoltaic panel.

[0041] The cart moves along the photovoltaic panel, driving the rotating wheel 44 to roll on the photovoltaic panel. The rotating wheel 44 drives the rotating shaft 71 to rotate through the connecting member 8. The rotating shaft 71 drives the rotating cylinder 72 and the cleaning brush 74 to rotate. The cleaning brush 74 cleans the surface of the photovoltaic panel. Due to the symmetric spiral arrangement of the cleaning brush 74, during the rotation or movement of the spiral cleaning brush 74, stains such as sand grains can be swept up from the surface of the photovoltaic panel. At this time, the diversion groove 75 and the spiral plate 76 can timely collect the sand grains swept up by the cleaning brush 74.

[0042] The runner 44 drives the rotating rod 45 to rotate, causing the rotating rod 45 to drive the outer rib 46 to rotate. At this time, extrusion occurs between the rib 46 and the outer convex block 68, causing the rib 46 to drive the convex block 68 to move downward. At this time, the convex block 68 drives the square plate 61 and the sliding rod 62 to move through the inclined plate 67. At this time, the sliding rod 62 moves downward inside the annular groove 43, further compressing the spring 66 to deform under force, causing the round rod 47 to slide inside the square groove 65 at the bottom of the connecting plate 63. Thus, the positioning groove 64 on the side of the connecting plate 63 approaches the cleaning assembly 7 and contacts the outer bristles of the cleaning brush 74. After the bristles contact the positioning groove 64, they disperse, thereby achieving the cleaning of the bristles and preventing sand grains from getting stuck between the bristles.
