Description

Technical Field

[0001] This invention belongs to the field of operation and maintenance cleaning technology, specifically a photovoltaic panel operation and maintenance cleaning device. Background Technology

[0002] With the rapid development of the photovoltaic industry, photovoltaic power generation has become one of the important renewable energy sources. As the core component of a photovoltaic power generation system, photovoltaic panels are prone to accumulating dust, bird droppings, leaves, and other contaminants on their surface, affecting their light absorption efficiency and thus reducing power generation efficiency. To maintain the efficient operation of the photovoltaic system, regular cleaning of the photovoltaic panel surface is crucial.

[0003] Existing photovoltaic (PV) cleaning devices perform well in removing dust and light stains from PV panel surfaces, but they fall short when dealing with more stubborn stains. These sticky stains, such as bird droppings and tree sap, adhere strongly and are difficult to remove completely by conventional cleaning methods, resulting in unsatisfactory cleaning results. Furthermore, existing cleaning devices often leave the PV panel surface relatively wet after cleaning. This moisture easily attracts dust and pollutants from the air. Once dust adheres to the damp PV panel surface, it is difficult to detach naturally, causing the PV panel to quickly become contaminated again, thus affecting its power generation efficiency.

[0004] Therefore, a photovoltaic panel maintenance and cleaning device is proposed to solve the above problems. Summary of the Invention

[0011] Preferably, a storage bin is connected to the upper part of the wheel frame, one side of the storage bin extends to the lower part of the wheel frame, and both sides of the storage bin are connected to a bent pipe located below the wheel frame. The other end of the bent pipe faces the circular perforated plate and is connected to a solenoid valve.

[0012] Preferably, a discharge box is installed on the inner side of the movable frame above the cleaning wheel. Several round tubes are connected above the discharge box. The top of the round tubes passes through the wheel frame and extends into the interior of the storage box and is connected to a feeding head. Several feeding ports are opened around the outside of the feeding head. A round sleeve that can close the feeding ports is movably sleeved on the outside of the feeding head.

[0013] Preferably, it further includes a blocking mechanism disposed below the wheel frame. The blocking mechanism includes a connecting block installed below the wheel frame. A movable block is slidably installed inside the connecting block and connected to a movable frame. A fixed rod is connected to the bottom end of the movable block.

A second spring located inside the stop plate is connected to the bottom end of the fixed rod, and the other end of the second spring is connected to the stop plate.

[0014] Preferably, it further includes a dust collection mechanism and a drying mechanism.

[0016] Preferably, a collection box is movably fitted inside the collection box, and an air filter is installed inside the collection box.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention, by setting up a scraper and cleaning wheel, allows water stains on the photovoltaic panel surface to be scraped downwards by the scraper as the wheel frame moves downwards along the inclined surface of the photovoltaic panel. When stubborn stains are not removed by the brush, the scraper comes into contact with the stain as the wheel frame moves, restricting its movement. At this time, the scraper, connecting rod, and connecting plate move backwards relative to the wheel frame, stretching the tension spring. Due to the movement of the connecting plate, the first round shaft drives the movable arm to rotate, simultaneously squeezing and pushing the second round shaft, the movable frame, and the cleaning wheel downwards. At this time, the first spring is compressed, ultimately causing... When the cleaning wheel comes into contact with the stain, the rotation of the second transmission wheel can drive the first transmission wheel and the movable sleeve to rotate via the first belt. The rotation of the movable sleeve can drive the hexagonal rod to rotate, and the rotation of the first transmission wheel can mesh and drive the first bevel gear to rotate, which in turn drives the cleaning wheel to rotate. Due to the rotation of the cleaning wheel, it can perform targeted cleaning on areas with more viscous stains. This design can identify stains and perform targeted cleaning on highly viscous stains, improving the cleaning intensity of the cleaning device and thus improving the cleaning effect on the surface of the photovoltaic panel.

[0019] 2. This invention, by setting up a discharge box and a stop plate, allows the discharge box to move downwards due to the descent of the moving frame. Simultaneously, the circular pipe, inlet, and feed head move downwards inside the circular sleeve. When the cleaning wheel abuts against the photovoltaic panel, the feed inlet on the feed head moves to the outside of the circular sleeve, releasing the inlet seal. At this time, the cleaning liquid inside the storage tank flows into the discharge box through the inlet, feed head, and circular pipe, and then flows onto the cleaning wheel. As the cleaning wheel rotates, it mixes the cleaning liquid with the highly viscous dirt... The cleaning solution fully contacts the stains, allowing it to react and break down even the most stubborn stains, thus achieving a replenishing effect and accelerating the cleaning of these stains. As the moving frame descends, it lowers the moving block, the fixed rod, and the abutment, causing the abutment to contact the surface of the photovoltaic panel. Simultaneously, the spring is compressed, and the contact of the abutment prevents the cleaning solution from flowing out of the discharge box from down the slope of the photovoltaic panel, reducing the rapid loss of the cleaning solution and increasing the reaction time between the cleaning solution and the stains.

[0020] 3. By setting up a heat-conducting plate and a convex lens, during the movement of the wheel frame, the operation of the fan can draw in the dust adhering to the surface of the photovoltaic panel through the exhaust pipe, collection box, and exhaust port. The dust is drawn into the collection box through the exhaust port and blocked by the air filter and collected inside the collection box. Due to the effect of sunlight, the convex lens focuses the light and shines it onto the heat-conducting plate, thereby increasing the temperature of the heat-conducting plate. At the same time, the air drawn in by the fan can be discharged into the exhaust box through the exhaust pipe. The airflow carries away the heat on the heat-conducting plate and blows hot air onto the photovoltaic panel, thereby accelerating the drying of the photovoltaic panel surface and preventing the photovoltaic panel surface from re-adsorbing dust and pollutants from the air.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 9 As shown, the present invention provides a photovoltaic panel maintenance and cleaning device, including a wheel frame 1, a connecting frame 2, and a high-intensity cleaning mechanism 5;

[0033] The connecting frame 2 is mounted on the wheel frame 1, and the forced cleaning mechanism 5 is mounted below the wheel frame 1;

[0034] The forced cleaning mechanism 5 includes a mounting block 51, which is mounted on a wheel frame 1. A connecting rod 52 is movably sleeved inside the mounting block 51. One end of the connecting rod 52 is connected to a scraper 53, and the other end is connected to a connecting plate 54. A tension spring 55 located outside the connecting rod 52 connects the mounting block 51 and the connecting plate 54. Limiting rods 56 are connected inside both sides of the mounting block 51. A movable frame 57 located inside the mounting block 51 is movably sleeved outside the limiting rods 56. A cleaning wheel 58 is movably mounted inside the movable frame 57. A movable arm 514 is movably mounted outside the mounting block 51. A round shaft 516 located inside the movable arm 514 is connected to the outside of the movable frame 57. A connecting plate 54 is connected to a... The movable arm 514 has a circular shaft 515 inside. The outer side of the movable frame 57 is connected to a fixed block 519. The fixed block 519 has a bevel gear 520 that is coaxially connected to the cleaning wheel 58. The outer side of the wheel frame 1 has a movable sleeve 517. The movable sleeve 517 has a matching hexagonal rod 518 inside. The bottom end of the hexagonal rod 518 extends into the fixed block 519 and is connected to 523. 523 meshes with the bevel gear 520. The movable sleeve 517 has a transmission wheel 521 above the wheel frame 1 on its outer side. The limit rod 56 has a spring 524 on its outer side. One end of the spring 524 is connected to the movable frame 57, and the other end of the spring 524 is connected to the mounting block 51.

[0035] Using the above scheme: When the wheel frame 1 moves downward along the slope of the photovoltaic panel, the water stains on the surface of the photovoltaic panel can be scraped off by the scraper 53. When the sticky stains are not cleaned off by the brush 83, as the wheel frame 1 moves, the scraper 53 can come into contact with the stains, thus restricting the movement of the scraper 53. At this time, the scraper 53, the connecting rod 52, and the connecting plate 54 move backward relative to the wheel frame 1, causing the tension spring 55 to be stretched. Due to the movement of the connecting plate 54, the first round shaft 515 can drive the movable arm 514 to rotate, while simultaneously squeezing and pushing the second round shaft 516 and the movable frame 57. As the cleaning wheel 58 moves downward, the spring 524 is compressed, eventually bringing the cleaning wheel 58 into contact with the stain. Due to the rotation of the transmission wheel 62, the transmission wheel 521 and the movable sleeve 517 are driven to rotate via the belt 522. The rotation of the movable sleeve 517 drives the hexagonal rods 518 and 523 to rotate. The rotation of 523 engages and drives the bevel gear 520 to rotate, which in turn drives the cleaning wheel 58 to rotate. The rotation of the cleaning wheel 58 allows it to perform targeted cleaning of areas with sticky stains.

[0036] like Figure 6 , Figure 7 and Figure 8As shown, it also includes a drive mechanism 6, which is mounted on the wheel frame 1. The drive mechanism 6 includes a power motor 61, a transmission wheel 62 fixedly sleeved on the output shaft of the power motor 61, and a transmission wheel 63 located above the transmission wheel 62 fixedly sleeved on the output shaft of the power motor 61. A belt 522 is used to drive the transmission wheel 62 and the transmission wheel 62.

[0037] The above scheme is adopted: As the power motor 61 runs, it can drive the transmission wheel 62 and the transmission wheel 63 to rotate. As the transmission wheel 63 rotates, it can drive the transmission wheel 87 and the shaft 81 to rotate through the belt 64. As the transmission wheel 62 rotates, it can drive the transmission wheel 521 and the movable sleeve 517 to rotate through the belt 522, thereby achieving the driving effect.

[0038] like Figure 8 As shown, it also includes a cleaning mechanism 8, which is mounted on the wheel frame 1. The cleaning mechanism 8 includes two rotating shafts 81, which are movably mounted on the wheel frame 1. The bottom end of the rotating shaft 81 is connected to a perforated plate 82, and a brush 83 is connected below the perforated plate 82. A transmission wheel 88 located above the wheel frame 1 is fixedly sleeved on the outside of the rotating shaft 81. There are two transmission wheels 88, and a belt 89 is used to drive between the two transmission wheels 88. A transmission wheel 87 below the transmission wheel 88 is fixedly sleeved on the outside of one rotating shaft 81. The transmission wheel 87 is driven by the transmission wheel 63 through a belt 64.

[0039] The above scheme is adopted: under the transmission action of belt 3 89, the two transmission wheels 5 88 are driven to rotate. Due to the rotation of shaft 81, the perforated plate 82 and brush 83 can be driven to rotate and clean the dust on the photovoltaic panel, thereby achieving the cleaning of stains on the surface of the photovoltaic panel.

[0040] like Figure 8 As shown, a storage box 84 is connected to the upper part of the wheel frame 1. One side of the storage box 84 extends to the lower part of the wheel frame 1. Both sides of the storage box 84 are connected to bent pipes 85 located below the wheel frame 1. The other end of the bent pipe 85 faces the circular hole plate 82 and is connected to a solenoid valve 86.

[0041] Using the above solution: As the solenoid valve 86 is opened, the cleaning fluid inside the storage tank 84 flows into the perforated plate 82 through the bent pipe 85. The fluid is then applied to the brush 83 through the perforated holes on the perforated plate 82. The brush 83, in conjunction with the cleaning fluid, cleans the surface of the photovoltaic panel, thereby removing most of the non-adhesive stains from the surface of the photovoltaic panel.

[0042] like Figure 2 and Figure 6As shown, a discharge box 59 is installed on the inner side of the movable frame 57, located above the cleaning wheel 58. Several round tubes 510 are connected above the discharge box 59. The top of the round tubes 510 passes through the wheel frame 1 and extends into the interior of the storage box 84 and is connected to the feed head 511. Several feed ports 512 are opened around the outside of the feed head 511. A round sleeve 513 that can close the feed port 512 is movably sleeved on the outside of the feed head 511. The top of the round sleeve 513 is connected to the storage box 84.

[0043] Using the above scheme: As the moving frame 57 descends, it can drive the discharge box 59 to move downwards. At the same time, the circular pipe 510, the inlet 512, and the feed head 511 move downwards inside the circular sleeve 513. When the cleaning wheel 58 comes into contact with the photovoltaic panel, the inlet 512 on the feed head 511 will move to the outside of the circular sleeve 513, releasing the closure of the inlet 512. At this time, the cleaning liquid inside the storage box 84 will flow into the discharge box 59 through the inlet 512, the feed head 511, and the circular pipe 510, and then flow to the cleaning wheel 58 through the discharge box 59. As the cleaning wheel 58 rotates, the cleaning liquid will come into full contact with the sticky stains. The cleaning liquid reacts fully with the sticky stains to decompose the stains, thereby achieving the effect of replenishing the liquid.

[0044] like Figure 2 As shown, it also includes a blocking mechanism 7, which is located below the wheel frame 1. The blocking mechanism 7 includes a connecting block 71, which is installed below the wheel frame 1. A movable block 72 is slidably installed inside the connecting block 71. The movable block 72 is connected to the movable frame 57. A fixed rod 73 is connected to the bottom end of the movable block 72. A stop plate 74 located inside the connecting block 71 is movably sleeved on the outside of the fixed rod 73. A second spring 75 located inside the stop plate 74 is connected to the bottom end of the fixed rod 73. The other end of the second spring 75 is connected to the stop plate 74.

[0045] Using the above scheme: As the moving frame 57 descends, it can drive the moving block 72, the fixed rod 73 and the abutment plate 74 to descend, so that the abutment plate 74 abuts against the surface of the photovoltaic panel. At the same time, the spring 75 is compressed. Due to the abutment plate 74, the cleaning liquid flowing out of the discharge box 59 can be blocked from flowing down the slope of the photovoltaic panel, so as to reduce the rapid loss of cleaning liquid and increase the reaction time between the cleaning liquid and the stains.

[0046] like Figure 2As shown, it also includes a dust collection mechanism 3 and a drying mechanism 4. The dust collection mechanism 3 is installed on the storage box 84, and the drying mechanism 4 is installed inside the wheel frame 1. The dust collection mechanism 3 includes a fan 31, which is installed on the storage box 84. One side of the fan 31 is connected to an exhaust pipe 33, and the other end of the exhaust pipe 33 is connected to a collection box 34. The collection box 34 is installed on the wheel frame 1, and the other side of the collection box 34 is connected to an exhaust port 37. The other end of the exhaust port 37 extends to the bottom of the wheel frame 1, and the other end of the fan 31 is connected to an exhaust pipe 32.

[0047] Using the above solution: Due to the operation of the fan 31, the dust attached to the surface of the photovoltaic panel can be sucked out through the exhaust pipe 33, the collection box 34 and the exhaust port 37, and the dust is sucked into the inside of the collection box 35 through the exhaust port 37.

[0048] like Figure 2 and Figure 9 As shown, the drying mechanism 4 includes an air outlet box 41, which is installed inside the wheel frame 1. Several convex lenses 43 are installed on the upper part of the air outlet box 41. A heat-conducting plate 42 is installed inside the air outlet box 41. The air outlet pipe 32 is connected to the air outlet box 41.

[0049] The above solution works as follows: due to the effect of sunlight, the convex lens 43 focuses the light to form a focal point and shines on the heat-conducting plate 42, thereby increasing the temperature of the heat-conducting plate 42. At the same time, the gas drawn in by the fan 31 can be discharged into the air outlet box 41 through the air outlet pipe 32. Meanwhile, the airflow carries away the heat from the heat-conducting plate 42 and blows hot air onto the photovoltaic panel, thereby accelerating the drying of the photovoltaic panel surface and preventing the photovoltaic panel surface from re-adsorbing dust and pollutants from the air.

[0050] like Figure 2 As shown, a collection box 35 is movably connected inside the collection box 34, and an air filter 36 is installed inside the collection box 35.

[0051] Using the above method: Dust is drawn into the collection box 35 through the exhaust port 37 and blocked by the air filter 36 and collected inside the collection box 35. The collection box 35 can be removed from the collection box 34 to clean the dust inside the collection box 35.

[0052] Working principle and usage process of this invention:

[0053] The operator drives the sweeper and drives the robotic arm to place the device on the photovoltaic panel, so that the wheel frame 1 contacts the photovoltaic panel. The device moves downward on the photovoltaic panel under the movement of the drive arm. During the movement of the wheel frame 1, due to the operation of the fan 31, the dust attached to the surface of the photovoltaic panel can be sucked in through the exhaust pipe 33, the collection box 34 and the exhaust port 37. The dust is sucked into the collection box 35 through the exhaust port 37 and is blocked by the air filter 36 and collected inside the collection box 35.

[0054] As the power motor 61 operates, it drives the transmission wheel 62 and the transmission wheel 63 to rotate. The rotation of the transmission wheel 63 drives the transmission wheel 87 and the shaft 81 to rotate via the belt 64. Simultaneously, under the transmission action of the belt 89, the two transmission wheels 88 rotate. The rotation of the shaft 81 drives the perforated plate 82 and the brush 83 to rotate and clean the dust on the photovoltaic panel. At the same time, the solenoid valve 86 opens, and the cleaning liquid inside the storage tank 84 flows into the perforated plate 82 through the bent pipe 85. The liquid wets the brush 83 through the perforated holes on the perforated plate 82. The cleaning of the photovoltaic panel is achieved by the brush 83 and the cleaning liquid, thus cleaning most of the non-sticky stains on the surface of the photovoltaic panel.

[0055] As the wheel frame 1 moves downwards along the slope of the photovoltaic panel, the scraper 53 can scrape the water stains on the surface of the photovoltaic panel downwards. When the sticky stains are not cleaned by the brush 83, as the wheel frame 1 moves, the scraper 53 can come into contact with the stains, thus restricting the movement of the scraper 53. At this time, the scraper 53, connecting rod 52, and connecting plate 54 move backwards relative to the wheel frame 1, causing the tension spring 55 to be stretched. Due to the movement of the connecting plate 54, the first round shaft 515 can drive the movable arm 514 to rotate, while simultaneously squeezing and pushing the second round shaft 516, the movable frame 57, and the cleaning wheel 58 downwards. At this time, spring 524 is compressed, which eventually causes cleaning wheel 58 to come into contact with the stain. Due to the rotation of transmission wheel 62, transmission wheel 521 and movable sleeve 517 can be rotated through belt 522. Due to the rotation of movable sleeve 517, hexagonal rods 518 and 523 can be rotated. Due to the rotation of 523, bevel gear 520 can be engaged and rotated, which in turn drives cleaning wheel 58 to rotate. Due to the rotation of cleaning wheel 58, cleaning wheel 58 can perform targeted rotation cleaning on areas with more viscous stains under the action of rotation. The control end will stop the wheel frame 1 from moving further.

[0056] As the moving frame 57 descends, it causes the discharge box 59 to move downwards. Simultaneously, the circular pipe 510, the inlet 512, and the feed head 511 move downwards inside the circular sleeve 513. When the cleaning wheel 58 contacts the photovoltaic panel, the inlet 512 on the feed head 511 moves to the outside of the circular sleeve 513, releasing the seal on the inlet 512. At this time, the cleaning fluid inside the storage tank 84 will flow into the discharge box 59 through the inlet 512, feed head 511, and circular pipe 510, and then flow through the discharge box 59 onto the cleaning wheel 58. As the cleaning wheel 58 rotates... The cleaning solution comes into full contact with the sticky stains, and the cleaning solution reacts fully with the sticky stains to decompose them, thereby achieving the effect of replenishing the solution and accelerating the cleaning of sticky stains. As the moving frame 57 descends, it can drive the moving block 72, the fixed rod 73 and the abutment plate 74 to descend, so that the abutment plate 74 abuts against the surface of the photovoltaic panel. At the same time, the spring 75 is compressed. Due to the abutment plate 74, the cleaning solution flowing out of the discharge box 59 can be blocked from flowing down the slope of the photovoltaic panel, so as to reduce the rapid loss of the cleaning solution and increase the reaction time between the cleaning solution and the stains.

[0057] When the stain can be cleaned, the stain loses its blocking force on the scraper 53. Under the restoring force of the tension spring 55 and spring 524, the scraper 53 and cleaning wheel 58 are reset. At the same time, the feed inlet 512 continues to be closed by the sleeve 513, and the discharge box 59 stops the flow.

[0058] Although the scraper 53 can remove a lot of water stains, the surface of the photovoltaic panel is still relatively wet. Due to the effect of sunlight, the sunlight is focused by the convex lens 43 and shines on the heat-conducting plate 42, which can increase the temperature of the heat-conducting plate 42. At the same time, the gas drawn by the fan 31 can be discharged into the air outlet box 41 through the air outlet pipe 32. Meanwhile, the airflow carries away the heat on the heat-conducting plate 42 and blows hot air onto the photovoltaic panel, thereby accelerating the drying of the photovoltaic panel surface.
