Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic panel cleaning, in particular to a photovoltaic panel cleaning and maintenance device on a factory roof. Background Art

[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It consists of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon).

[0003] In the prior art, for example, Chinese patent publication number: CN219812125U discloses a cleaning and maintenance device for photovoltaic panels on the roof of a factory building, which relates to the technical field of cleaning equipment. The utility model includes a grip rod, and a convenient cleaning mechanism is provided at one end of the grip rod, and the convenient cleaning mechanism includes a shell, a power unit, a rotating unit, a transmission unit, a rotating unit, a fixed unit and a cleaning unit. One end of the grip rod is fixedly connected to the shell, and a power unit is provided at one end of the shell. A rotating unit is provided at one end of the power unit inserted in the shell, and transmission units are provided at both ends of the rotating unit. A rotating unit is provided at the lower end of the transmission unit, and a fixed unit is provided at the end of the rotating unit away from the shell.

[0004] However, the above patents have the following deficiencies: A complete photovoltaic panel assembly is mainly composed of an inner lining board, a battery body, a metal outer frame and a glass mask. When used in a factory, multiple photovoltaic panel assemblies can be combined and formed in pairs and then laid flat on a well-lit roof. The subsequent cleaning and maintenance phase is mainly carried out from the outside of the battery to clean the retained matter on the surface of the glass mask to ensure its light transmittance, so that the built-in battery body always has a strong energy conversion efficiency. The equipment involved in the above patent improves the traditional structural layout, simplifies the cleaning components, improves ease of use, effectively saves labor and physical expenditure, and improves cleaning efficiency. However, there are still some shortcomings, such as: When photovoltaic panels are placed outside for a long time, dirt, pollutants, oil smoke, insect corpses, bird droppings, resin and other substances will cause an oil film to form on the surface of the glass mask. When rainwater falls on the surface of the glass mask, a large amount of water will hang on the wall. After the water droplets dry up, the sand and soil inside will be tightly attached to the surface of the glass mask. However, this equipment can only perform relatively simple dirt cleaning, but cannot change the easy-to-get-dirty nature of the glass mask and cannot extend the cleaning cycle.

[0005] The equipment is limited by its own structure and has a low level of automation, requiring manual assistance. During the cleaning process, problems such as excessive external force and human trampling may occur, leading to damage to the structure of the photovoltaic panel assembly.

[0006] Therefore, we proposed a cleaning and maintenance equipment for photovoltaic panels on the roof of a factory building to solve the problems raised above. Summary of the Invention

[0007] The purpose of the present invention is to provide a cleaning and maintenance equipment for photovoltaic panels on the roof of a factory building. Through the provided tiered cleaning mechanism, when the equipment body is transferred to the top of the pre-cleaned photovoltaic panel assembly, the flexible wool cover can fully contact the glass mask, and physical friction and water softening are used to complete the cleaning of dirt on the glass mask. Further, according to the dirt cleaning path, the spraying liquid is replaced, and the oil film remover is sprayed onto the high-speed rotating flexible wool cover, and the surface of the glass mask after dirt treatment is continued to be physically wiped. During the process, the oil film agent can be fully kneaded into the oil layer to promote chemical dissolution of the oil film, and complete the cleaning of the oil film on the surface of the glass mask, so as to solve the problems raised by the above-mentioned background technology.

A first hydraulic push rod 305 is fixedly installed inside the first locking frame 304, and retraction holes 306 are opened on both sides of the outer wall of the center box 303. By presetting the above components, the two first hydraulic push rods 305 are of equal specifications, and their inner shafts are extended in opposite directions. When the equipment is working, the auxiliary components can be used to cooperate to flexibly drive the sub-plate body 2 and its connected components to move horizontally left and right.

[0027] according to Figure 7 、 Figure 8 and Figure 9As shown, two first brackets 309 are fixedly installed on the bottom of the sub-plate body 2, and a group of L-shaped clamping sleeves 310 are welded on the opposite sides of the two first brackets 309, and the number of each group of L-shaped clamping sleeves 310 is two. A horizontal plate 311 is movably provided inside each first bracket 309, and a limiting block 312 is fixedly installed on both sides of the outer wall of each horizontal plate 311.

On the one hand, it provides the necessary conditions for the lateral movement of the auxiliary plate 2 and its connected components, and on the other hand, it ensures the stability of the cleaning component during operation.

[0029] according to Figure 8 and Figure 9 As shown, a first grafting plate 316 is welded to the opposite side of the two first brackets 309, and an electric push rod 317 is fixedly inserted inside each first grafting plate 316.

[0031] according to Figure 10 As shown, a first positioning sleeve 324 is fixedly installed inside each third bracket 323, a first cross bar 325 is movably inserted into the inner wall of each first positioning sleeve 324, a wheel body 326 is fixedly sleeved on the outer wall of each first cross bar 325, a first flange 327 is fixedly installed on the outer wall of the two third brackets 323, a driving motor 328 is fixedly inserted into the inner wall of each first flange 327, and the output end of each driving motor 328 is respectively connected to one end of the outer wall of a corresponding first cross bar 325. By presetting the above components, the mechanism is provided with a power component, so that the equipment can move back and forth on a photovoltaic panel assembly.

[0032] according to Figure 10 As shown, a group of limiting sleeves 329 are fixedly installed inside each second bracket 319, and a support rod 330 is fixedly inserted inside each limiting sleeve 329. One end of the outer wall of each group of support rods 330 is fixedly inserted inside a corresponding linkage plate 322.

[0033] according to Figure 7As shown, the bottom of the water tank 417 and the liquid storage tank 418 are fixedly installed with a third bracket 419, and the outer wall of each third bracket 419 is fixedly installed with a group of bases 420. The outer wall of each group of bases 420 is respectively fixedly installed with a first booster pump 421 and a stop valve 422. The output end of each first booster pump 421 is respectively connected to the liquid inlet end of a corresponding stop valve 422, and the output end of each first booster pump 421 is fixedly connected to a first pipe 423. The liquid inlet end of each first pipe 423 passes through the water tank 417 and the liquid storage tank 418 respectively. The bottom is connected with the interior of the water tank 417 and the liquid tank 418 respectively. The liquid outlet end of each stop valve 422 is fixedly connected with the second pipe 424. The liquid outlet end of each second pipe 424 passes through the outer wall of the first connector 414 and the second connector 415 respectively, and is connected with the interior of the first connector 414 and the second connector 415 respectively. Through the preset upper component, the clean water and oil film remover in the water tank 417 and the liquid tank 418 are respectively introduced into the corresponding two low-pressure spray guns 411 according to the cleaning process, and both act on the flexible wool sleeve 406.

[0034] according to Figure 4 and Figure 6 As shown, a fourth flange 432 is fixedly installed on the front surface of the water tank 417, and a second booster pump 433 is fixedly inserted into the inner wall of the fourth flange 432. The input end of the second booster pump 433 is connected to the interior of the water tank 417, and the output end of the second booster pump 433 is fixedly connected to a water hose 434, and the discharge end of the water hose 434 is connected to the liquid inlet end of the high-pressure spray gun 429. By presetting the above components, after the oil film on the glass mask is removed, the second booster pump 433 continuously introduces clean water into the high-pressure spray gun 429 and sprays it onto the glass mask at high speed to rinse off the oil film agent remaining on the glass mask.

[0035] The effect achieved by the entire mechanism is as follows: during the equipment preparation stage, the interior of the water tank 417 and the liquid tank 418 are filled with an appropriate amount of clean water and oil film agent in turn. When the equipment is placed in front of and behind a corresponding photovoltaic panel assembly, each second hydraulic push rod 321 is synchronously turned on to make its inner shaft extend outward at the same speed, pushing the third bracket 323 on each linkage plate 322 to expand outward until each wheel body 326 is aligned with the metal frame on the outside of the photovoltaic panel assembly. The drive motor 328 is turned on to enable the wheel body 326 connected thereto to obtain power. When the equipment is driven on the photovoltaic panel assembly, the flexible fleece 406 can be in full contact with the glass mask.

[0036] In the dirt cleaning stage, a first booster pump 421 is turned on, and the internal channel of the corresponding stop valve 422 is opened to start extracting the clean water stored in the water tank 417. The clean water is continuously transferred to the two connected low-pressure spray guns 411 through the first series pipe 412, the first pipe 423 and the second pipe 424, and sprayed onto the flexible wool cover 406. At the same time, the servo motor 408 is turned on and acts on the second cross bar 404 to make the roller 405 rotate at high speed inside the first U-shaped outer frame 401, continuously wiping the glass mask. The dirt gradually separates from the surface of the glass mask under the softening of the clean water. The equipment can complete the cleaning of part of the glass mask surface dirt from front to back under the workmanship of the driving components.

[0037] During the position adjustment stage, when the position of the flexible fleece 406 needs to be adjusted left or right, if it is adjusted to the left first, the electric push rod 317 at the corresponding position is turned on, and its shaft end extends outward to apply an upward thrust to the second grafting plate 318 connected thereto. By utilizing the movable connection between the L-shaped sleeve 310 and the limit block 312, the height of the electromagnetic plate 315 is slowly raised until it is aligned with the corresponding solid metal plate 308. The first hydraulic push rod 305 connected to the left is turned on, and its inner shaft extends outward to gradually make the solid metal plate 308 contact with the electromagnetic plate 315. Then, the electromagnetic plate 315 is adjusted. When power is supplied, the magnetic force generated on its surface can firmly adsorb the solid metal plate 308, completing the docking of the main plate 1 and the auxiliary plate 2. The position of the right electromagnetic plate 315 remains unchanged, and the inner axis of the left first hydraulic push rod 305 is continuously extended, driving the flexible fleece 406 to move it to the left. The dirt on this part of the glass mask is cleaned by the above method. Subsequently, the flexible fleece 406 is reset, and the left electromagnetic plate 315 is removed to complete the docking of the right solid metal plate 308 and the electromagnetic plate 315, and the dirt cleaning of the right part of the glass mask is continued.

[0038] In the oil film cleaning stage, when the dirt cleaning is completed, the flexible wool sleeve 406 is first reset, and the corresponding two low-pressure spray guns 411 continue to release clean water to clean the high-speed rotating flexible wool sleeve 406. After the time is up, the clean water release is turned off, and a first booster pump 421 and a stop valve 422 on the liquid storage tank 418 are opened to start extracting the oil film agent stored in the liquid storage tank 418. The oil film agent is then continuously introduced into the corresponding two low-pressure spray guns 411 through the connected second series pipe 413, the first pipe 423 and the second pipe 424, and sprayed onto the flexible wool sleeve 406. Through the above-mentioned dirt cleaning method, the position of the flexible wool sleeve 406 can be freely changed until the oil film on the surface of the entire glass mask is cleaned.

[0039] During the mechanism flushing stage, after the equipment is placed on the photovoltaic panel assembly, the steering motor 431 is turned on, and the movable connection between the external connecting frame 427 and the third cross bar 428 is used to drive the high-pressure spray gun 429 to perform an angular offset until the nozzle of the high-pressure spray gun 429 is aimed at the glass mask. When the dirt and oil film are cleaned, after part of the glass mask on a single path is processed, the equipment is reset and the second booster pump 433 is turned on, and clean water in the water tank 417 is extracted. The clean water is continuously transferred to the high-pressure spray gun 429 by the water hose 434. After being compressed by the nozzle, it is sprayed onto the glass mask at high speed, which can promptly flush away the dirt or oil film residue on the reset path.
