Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic panel maintenance device for photovoltaic power generation. Background Art

[0002] During the long-term use of solar street lights, the surface of the photovoltaic panels will inevitably be affected by some stains, mainly including bird droppings, shellac, etc. Since the photovoltaic panels are high above the ground, it is more troublesome to clean and maintain them. If not cleaned in time, these stains will gradually accumulate and affect the light transmittance of the photovoltaic panels, reducing the photoelectric conversion efficiency. In severe cases, this impact will lead to a hot spot effect, affecting the normal operation of the entire solar street light.

[0003] The Chinese invention patent with publication number CN117691936A discloses a photovoltaic panel maintenance device for photovoltaic power generation, including a fixed platform; a cylinder seat is installed on the upper end surface of the fixed platform; the telescopic end of the cylinder seat is fixedly connected to a support plate, and a counterweight block is arranged inside the fixed platform; a connecting beam is fixedly connected to the front end surface of the support plate; the ends of the two connecting beams away from the support plate are fixedly connected to a mounting frame; an electric telescopic rod 1 is fixedly connected to the inside of the mounting frame; an annular jacket on both sides is placed on the outside of the electric pole; then the telescopic end of the cylinder seat is controlled to drive the support plate to move upward, and when the protective mechanism moves to the side close to the photovoltaic panel, the cylinder seat is stopped, and the telescopic end of the electric telescopic rod 1 is controlled to move, so that the telescopic end drives the annular jacket to move toward the end of the electric pole. Under the clamping of the annular jacket on both sides, the stability of the protective mechanism during operation is improved, which is beneficial to the maintenance of the photovoltaic panel.

[0004] However, the above patent still has the following shortcomings in actual use: the patent uses the electric telescopic rod to drive the cleaning bag to move on the surface of the photovoltaic panel, and at the same time cooperates with the water in the water pump to moisten the cleaning bag, so as to achieve the removal of stains on the surface of the photovoltaic panel. However, after the bird droppings adhere to the surface of the photovoltaic panel, the hardness of the bird droppings will gradually increase with the increase of time. It is difficult to break the hard bird droppings by relying solely on the sponge cleaning bag. Although water can reduce the hardware of the bird droppings, the water will also mix with all the bird droppings powder, which will cause the water to become sewage. Using sewage to wipe the surface of the photovoltaic panel will make it dirtier. Only by using the continuously flowing water to dilute the sewage can the surface of the photovoltaic panel be cleaned. This causes the surface of the photovoltaic panel to take a long time to clean, which greatly reduces the cleaning efficiency of the surface of the photovoltaic panel. Summary of the invention

The placement angle of the two cantilevers 3 can be changed by the rotating mechanism 2, so that the clamping mechanism 4 also changes the placement angle synchronously, so that stains can be cleaned on the surface of the photovoltaic panels at different placement angles.

[0037] The rotating mechanism 2 includes two first rotating seats 21, a rotating motor 22, a synchronous shaft 23, a first sprocket 24 and a second sprocket 25. The two first rotating seats 21 are symmetrically arranged on the back of the vertical plate 141, the rotating motor 22 is fixedly connected to the back of the vertical plate 141, the synchronous shaft 23 is rotatably arranged on the two first rotating seats 21, the first sprocket 24 is fixedly connected to the output end of the rotating motor 22, the second sprocket 25 is fixedly connected to the synchronous shaft 23, the first sprocket 24 and the second sprocket 25 are connected by chain transmission, and the two cantilevers 3 are respectively connected to the two sides of the synchronous shaft 23.

[0039] The clamping mechanism 4 includes two clamping components, which are respectively arranged on the two cantilevers 3.

[0040] The two clamping electric push rods 41 work synchronously to drive the corresponding L-shaped clamping frames 42 to move relative to each other, and the telescopic pressing frame 422 can gradually abut against the side wall of the photovoltaic panel. The telescopic pressing frame 422 presses the spring 423, and the spring 423 is compressed. The two L-shaped clamping frames 42 clamp the photovoltaic panel.

After the photovoltaic panel is clamped and fixed, it is also convenient for the staff to replace the photovoltaic panel.

[0041] The switching component 54 is driven to move by the moving electric cylinder 51 , and the scraping component 52 and the cleaning component 53 move synchronously with the switching component 54 .

The sponge ring 532 is sleeved on the connecting pipe 531. The scraping roller 521 and the connecting pipe 531 are connected to the switching assembly 54.

[0043] The switching assembly 54 includes a switching electric push rod 541, a sliding seat 542 and a second rotating seat 543. A connecting plate 5411 is installed on the output end of the switching electric push rod 541, and a connecting rod 5412 is provided on the connecting plate 5411. A slider 5421 is slidably provided on the sliding seat 542. A connecting seat 5422 is provided on the top of the slider 5421. A rack 5423 is provided on the side wall of the connecting seat 5422. A rotating shaft 5431 is rotatably provided on the second rotating seat 543. A sector gear 5432 is installed at one end of the rotating shaft 5431. A V-shaped plate 5433 is provided at the other end of the rotating shaft 5431. A water passage cavity 5434 is provided at one end of the V-shaped plate 5433. A water inlet 5435 communicating with the water passage chamber 5434 is provided on the outer wall of 5433, a water outlet 5436 communicating with the water passage chamber 5434 is provided on the side wall of the V-shaped plate 5433, the switching electric push rod 541, the slide seat 542 and the second rotating seat 543 are arranged on the slide, the rack 5423 is meshed with the fan gear 5432, the connecting rod 5412 is fixedly connected to the slider 5421, the connecting pipe 531 is detachably connected to the water outlet 5436, the water inlet 5435 is communicated with the water pump 16 through a pipeline, the scraping roller 521 is connected to the end of the V-shaped plate 5433 away from the connecting pipe 531, and the scraping roller 521 and the connecting pipe 531 are parallel.

[0044] The electric push rod 541 is switched to drive the connecting plate 5411 to move, the connecting plate 5411 drives the connecting rod 5412 to move, the connecting rod 5412 drives the slider 5421 to slide on the slide seat 542, the slider 5421 drives the connecting seat 5422 and the rack 5423 to move synchronously, the rack 5423 drives the fan gear 5432 to rotate, the fan gear 5432 drives the rotating shaft 5431 to rotate synchronously, and the V-shaped plate 5433 rotates synchronously with the rotating shaft 5431. Then, one of the two The end of the protrusion 522 contacts the surface of the photovoltaic panel, and then the mobile electric cylinder 51 drives its slide to move, and the slide drives the switching electric push rod 541, the slide seat 542, the second rotating seat 543, and the V-shaped plate 5433 to move synchronously, and the V-shaped plate 5433 drives the scraping roller 521 and the connecting pipe 531 to move synchronously, and the scraping roller 521 moves synchronously with the V-shaped plate 5433, and the protrusion 522 can shovel hard bird droppings, and the bird droppings can be shoveled and moved synchronously with the protrusion 522 after being shoveled. Then, the bird droppings can fall onto the guide plate 74, and then the electric push rod 541 is switched to drive the slider 5421 to move in the opposite direction, and the protrusion 522 can be away from the surface of the photovoltaic panel. Then, the moving electric cylinder 51 drives the V-shaped plate 5433 to return to the initial position, and then the electric push rod 541 is switched to drive the slider 5421 to continue to move in the opposite direction, and the sponge ring 532 contacts the surface of the photovoltaic panel. Then, the water pump 16 works to transport the water in the water tank 15 to the water cavity, and the water can enter the connecting pipe 531, and then the water penetrates into the sponge ring 532 through the water permeable hole 533. Then, the moving electric cylinder 51 drives the V-shaped plate 5433 to move again, and the water can seep out from the sponge ring 532 and flow on the surface of the photovoltaic panel, and the surface of the photovoltaic panel is wetted. Then, the moving sponge ring 532 can wipe the surface of the photovoltaic panel, and the sewage after wiping can flow to the guide plate 74, so that the surface stains of the photovoltaic panel can be completely removed.

[0045] Preferably, the ends of the scraping roller 521 and the connecting tube 531 of one stain cleaning mechanism 5 are provided with an embedded positioning groove 523, and the ends of the scraping roller 521 and the connecting tube 531 of the other stain cleaning mechanism 5 are provided with a positioning plug 524 that cooperates with the embedded positioning groove 523. The cooperation between the positioning plug 524 and the embedded positioning groove 523 can enable the scraping roller 521 and the connecting tube 531 of the stain cleaning mechanism 5 to complete simple docking, and the two stain cleaning mechanisms 5 can work stably and synchronously.

[0046] Since a large amount of water stains will remain on the surface of the photovoltaic panel after being wetted by water, if these water stains are not cleaned in time, external dust can adhere to the water stains to form stains again. Therefore, an air-drying component 6 is provided to clean the water stains. The air-drying component 6 includes a fan 61, a blow hood 62 and two third rotating seats 63. Connecting shafts are provided on both sides of the blow hood 62, one of the connecting shafts is provided with a third sprocket 621, and a fourth sprocket 231 is provided on the synchronization shaft 23.

[0047] Wind is generated by the fan 61, and then transmitted to the blow hood 62 through the pipeline. The blow hood 62 guides the wind to the surface of the photovoltaic panel, and then the water stains can be dried by the wind. The third sprocket 621, the fourth sprocket 231 and the chain cooperate to make the blow hood 62 rotate synchronously with the cantilever 3, so that the blowing port of the blow hood 62 can always face the surface of the photovoltaic panel.

[0048] After the sewage and the crushed bird droppings fall onto the guide plate 74, the sewage can guide the water to the sewage collection area 72 through the water holes, and the water holes can filter out impurities in the sewage.

The contact ball 752 abuts against the bottom of the head end of the guide plate 74, and a buffer inclined plate 742 is provided at the top of the guide plate 74 near the tail end.

[0050] The shaking motor 75 drives the rotating rod 751 to rotate, and the rotating rod 751 drives the abutting ball 752 to gradually approach the bottom of the head end of the guide plate 74, and then the abutting ball 752 abuts against the bottom of the head end of the guide plate 74, and the abutting ball 752 drives the guide plate 74 to rotate around the axis of the shaking shaft 741, and the abutting ball 752 gradually separates from the guide plate 74, and the guide plate 74 returns to its original position by using its own gravity, and the guide plate 74 can shake in this cycle, which can prevent the water through hole from being blocked. However, this will invisibly speed up the flow speed of the sewage, and a large amount of sewage is also collected in the impurity collection area 73, which makes it impossible to achieve the purpose of collecting sewage and impurities separately. Therefore, the buffer inclined plate 742 is provided to hinder the flow of sewage and prolong the time that the sewage stays on the guide plate 74. The screened impurities can be accumulated on the buffer inclined plate 742, and the impurities can be shaken once when the guide plate 74 shakes once, and the impurities can gradually separate from the buffer inclined plate 742 and fall into the impurity collection area 73.

[0051] A drain port 721 is provided at the bottom of the sewage collection area 72 , and a detachable cover 722 is provided on the drain port 721 . A discharge port 731 is provided at the bottom of the impurity collection area 73 , and a detachable material box 732 is provided on the discharge port 731 .

[0052] Sewage can be collected in the sewage collection area 72. By removing the cover 722, the sewage can be discharged from the drain port 721. The screened sewage can be recycled to reduce the waste of water resources. Impurities can pass through the impurity collection area 73 and enter the material box 732. By removing the material box 732, the impurities collected in it can be discharged in a centralized manner. If there are a lot of bird droppings in the impurities, these bird droppings can be poured onto vegetables and other plants to become fertilizer.

[0053] The positioning mechanism 8 includes two horizontal plates 81 , on which a horizontally arranged positioning electric push rod 82 is provided, and a positioning clamp frame 83 is installed on the output end of the positioning electric push rod 82 . The two horizontal plates 81 are symmetrically arranged on the front part of the vertical plate 141 .

[0054] The two positioning electric push rods 82 work synchronously to drive the corresponding positioning clamping frames 83 to move. The two positioning clamping frames 83 can be clamped on the pole, thus improving the working stability of the entire device.
