Description

Technical Field

[0001] The invention relates to the field of photovoltaic maintenance, and in particular to a rooftop photovoltaic operation and maintenance cleaning device. Background Art

[0002] Photovoltaic panels are exposed to the natural environment, and dust, bird droppings, leaves and other debris are very likely to adhere to their surfaces. The accumulation of dust will significantly reduce the light transmittance of photovoltaic panels. According to relevant studies, even a thin layer of dust may cause the power generation efficiency of photovoltaic panels to decrease by 10%-30%. Obstructions such as bird droppings and leaves not only affect light absorption, but may also form shadows in some areas, causing hot spot effects, making the temperature of photovoltaic panels too high, accelerating the aging of the cells, shortening the service life of photovoltaic panels, and in severe cases even causing photovoltaic panels to burn out, resulting in economic losses.

[0003] The roof environment is complex and has a certain slope. Cleaners are at high risk when working on the roof, and are prone to slips, falls, and other accidents. On the other hand, manual cleaning efficiency is extremely low, and it is difficult to meet the cleaning needs of large-scale rooftop photovoltaic systems. In addition, some traditional simple cleaning tools, such as mops and brooms, are not easy to clean photovoltaic panels that are far away from the ridge and below the roof slope during the cleaning process. At the same time, the cleaning effect on photovoltaic panels is not good, which leads to a decrease in the photovoltaic panels' ability to receive sunlight, resulting in a lower power generation efficiency of photovoltaic panels.

A fixed frame is fixedly connected between one side of the two connecting rods, and the fixed frame is sleeved on the rotating sleeve. A pull rod is slidably connected to the lower part of the fixed frame, and two round rods are fixedly connected to the upper surface of the pull rod. Eight groups of sliding grooves are opened on the annular tube, and each group of sliding grooves has two. The eight groups of sliding grooves of the annular tube are slidably connected to arc seats, and each arc seat is respectively connected to the sliding groove on the annular tube with a reset spring, and each arc seat is fixedly connected to a mounting frame on the side away from the center of the annular tube, and a cleaning sponge is fixedly connected to each mounting frame.

During the process of multiple reciprocating movements, the cleaning sponge continuously uses the friction force to gradually clean all kinds of dust and stains on the surface of the photovoltaic panel, so that the surface of the photovoltaic panel is restored to a clean state, ensuring that it can efficiently absorb solar energy and maintain good power generation performance.

The water flow forms a uniform water flow impact on both sides of the cleaning sponge. On the one hand, it can wet the cleaning sponge, so that it can better absorb dust and stains and enhance the cleaning effect; on the other hand, the water flow can also directly wash away the loose impurities on the surface of the photovoltaic panel, and cooperate with the wiping effect of the cleaning sponge to complete the cleaning task of the photovoltaic panel surface, ensuring the cleanliness of the photovoltaic panel surface and the photoelectric conversion performance.

[0014] 3. The toothless bevel gear drives the annular tube to rotate intermittently. As the annular tube rotates, the cleaning sponge that was originally in contact with the surface of the photovoltaic panel will be gradually replaced, and a new cleaning sponge will be able to contact the surface of the photovoltaic panel, ensuring that the cleaning sponge always maintains good cleaning ability and cleaning effect, thereby continuously and efficiently cleaning the surface of the photovoltaic panel in the future.

[0015] 4. Due to the relative movement between the wiping roller and the cleaning sponge and the friction generated by the extrusion, stains, dust and other impurities on the surface of the cleaning sponge are easier to remove, thereby effectively enhancing the wiping effect of the cleaning sponge and allowing the cleaning sponge to better maintain a clean state, so that it can achieve a better cleaning effect when the surface of the photovoltaic panel is cleaned later.

[0032] The flushing component includes a three-way pipe 601, which is fixedly connected to the inside of the rotating sleeve shaft 4051. The side of the three-way pipe 601 away from the rotating sleeve shaft 4051 is fixedly connected to a water supply ring 602, and eight opening and closing valves 603 are fixedly connected to the water supply ring 602.

The photovoltaic panel 101 on the roof is in an inclined setting. When the photovoltaic panel 101 on the roof needs to be cleaned, the staff first passes the traction rope through the two perforations on the pull ring strip 2, moves the device to the center of the roof, and then puts the device above the photovoltaic panel 101. The two sides of the photovoltaic panel 101 squeeze the two clamping wheels 304 and the two moving seats 302 respectively, and the two squeezing springs 303 are squeezed. The deformation force of the squeezing springs 303 pushes the two moving seats 302 and the two clamping wheels 304 to clamp and limit the two sides of the photovoltaic panel 101 respectively, so that the bracket 1 can move stably on the photovoltaic panel 101, thereby making it possible to better clean the surface of the photovoltaic panel 101 later. The staff will The water pipe is connected to the three-way pipe 601 and the external water pump is started. Under the limiting action of the lower convex part of the fixed baffle 606, the opening and closing head 604 at the bottom is inconsistent with the other seven opening heads, so that the water spraying pipe 605 and the opening and closing valve 603 at the bottom are in a connected state.

The water flow forms a uniform water flow impact on both sides of the cleaning sponge 4014. On the one hand, it can wet the cleaning sponge 4014, so that it can better absorb dust and stains and enhance the cleaning effect; on the other hand, the water flow can also directly wash away the loose impurities on the surface of the photovoltaic panel 101, and cooperate with the wiping effect of the cleaning sponge 4014 to jointly complete the cleaning task of the surface of the photovoltaic panel 101, and ensure the cleanliness and photoelectric conversion performance of the surface of the photovoltaic panel 101. Then, the servo motor 403 is started and the traction rope is unwound. Under the action of gravity, the bracket 1 moves along the tilting direction of the photovoltaic panel 101. The output shaft of the servo motor 403 rotates forward to drive the power shaft 405, the rotating shaft 407 and the two cams 408 to rotate together. The two cams 408 rotate forward to intermittently squeeze the two round rods 4011 to move, and the two round rods 4011 drive the pull rod 4010 to move intermittently along the guide of the fixed frame 409.The two ends of the pull rod 4010 push the two arc seats 4012 at the bottom to move intermittently, and the two arc seats 4012 intermittently squeeze the two return springs 40121 respectively, and the two arc seats 4012 at the bottom drive the installation frame 4013 at the bottom and the cleaning sponge 4014 on the installation frame 4013 to move together. In the process of multiple reciprocating movements, the cleaning sponge 4014 continuously uses the friction force to gradually clean all kinds of dust and stains on the surface of the photovoltaic panel 101, so that the surface of the photovoltaic panel 101 is restored to a clean state, ensuring that it can efficiently absorb solar energy and maintain good power generation performance. The reciprocating movement of the pull rod 4010 drives the fixed rack 504 to move reciprocatingly together, and the return spring 4012 1, the pull rod 4010 pushes the fixed rack 504 to move, and under the action of the overrunning clutch 502, the fixed rack 504 drives the fixed gear 503 to reverse, and the rotating shaft 501 and the toothless bevel gear 505 do not rotate. Under the action of the reset spring 40121, the pull rod 4010 drives the fixed rack 504 to reset, and the fixed rack 504 resets and drives the fixed gear 503 to rotate forward, and the forward rotation of the fixed gear 503 drives the rotating shaft 501, the overrunning clutch 502 and the toothless bevel gear 505 to rotate forward by a quarter of a circle, and the pull rod 4010 and the fixed rack 504 move back and forth many times, so that the toothless bevel gear 505 meshes with the ring gear 506, and the toothless bevel gear 505 drives the ring gear 506, the tripod 404, the rotating shaft 407 sleeve, and the annular tube 4 06 rotates one eighth of a circle together, the annular tube 406 rotates one eighth of a circle, driving the two arc-shaped seats 4012 at the bottom to rotate one eighth of a circle as well, the two arc-shaped seats 4012 at the bottom are disengaged from the two ends of the pull rod 4010, the annular tube 406 rotates one eighth of a circle, and also drives the three-way pipe 601, the water delivery ring 602, the opening and closing valve 603, the opening and closing head 604 and the water spray pipe 605 to rotate, the opening and closing head 604 at the bottom contacts the upper convex part of the fixed blocking rod 606 during the one eighth rotation, the upper convex part of the fixed blocking rod 606 squeezes the opening and closing head 604 in the rotating process to reset, the opening and closing head 604 resets so that the opening and closing valve 603 and the water spray pipe 605 are closed, and the opening and closing head 604 at the side is The lower convex part is squeezed, and the opening and closing valve 603 on the side is connected with the water spray pipe 605. The two arc seats 4012 on the side are located at the bottom of the annular tube 406 after rotating one-eighth of a circle. The two ends of the pull rod 4010 are re-engaged with the two arc seats 4012 at the bottom after replacement, and the annular tube 406 is driven to rotate intermittently through the toothless bevel gear 505. As the annular tube 406 rotates, the cleaning sponge 4014 that was originally in contact with the surface of the photovoltaic panel 101 will be gradually replaced, and the new cleaning sponge 4014 can be in contact with the surface of the photovoltaic panel 101, ensuring that the cleaning sponge 4014 always maintains a good cleaning ability and cleaning effect, so as to continuously and efficiently clean the surface of the photovoltaic panel 101 in the future. After the surface of the photovoltaic panel 101 is cleaned,The staff turns off the servo motor 403 and the external water pump and pulls the bracket 1 back through the traction rope. The servo motor 403 no longer drives the power shaft 405 and the rotating shaft 407 to rotate together.

[0033] Embodiment 2 is based on embodiment 1, as Figure 8 and Fig.10 As shown, an erasing member is also included, and the erasing member includes a rotating rod 701. Two rotating rods 701 are rotatably connected between the brackets 1. Erasing rollers 702 are fixedly connected to the two rotating rods 701, and the same side of the two rotating rods 701 is fixed.

[0034] The forward rotation of the annular tube 406 drives the toothless gear ring 704 to rotate forwardly, and the teeth of the toothless gear ring 704 gradually mesh with the pinion 703. The forward rotation of the toothless gear ring 704 drives the pinion 703 and the rotating rod 701 to reverse, and the reverse rotation of the rotating rod 701 drives the erasing roller 702 to reverse. The forward rotation of the annular tube 406 drives the arc seat 4012, the mounting frame 4013 and the cleaning sponge 4014 to rotate forward, and the erasing roller 702 squeezes the cleaning sponge 4014. The cleaning sponge 4014 is squeezed, and the cleaning sponge 4014 still keeps rotating in the squeezed state. Due to the relative movement between the erasing roller 702 and the cleaning sponge 4014 and the friction generated by the squeezing, the stains, dust and other impurities on the surface of the cleaning sponge 4014 are more easily removed, thereby effectively enhancing the erasing effect of the cleaning sponge 4014, allowing the cleaning sponge 4014 to better maintain a clean state, so that it can play a better cleaning effect when the surface of the photovoltaic panel 101 is cleaned later. The annular tube 406 does not rotate and no longer drives the toothless gear ring 704 to rotate, and the toothless gear ring 704 no longer drives the pinion 703 to rotate.
