Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and specifically 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 panel will inevitably be affected by some stains, mainly including bird droppings, insect glue, etc. Since the photovoltaic panel is relatively high from the ground, it is rather troublesome to clean and maintain. If not cleaned in time, these stains will gradually accumulate, affect the light transmittance of the photovoltaic panel, and reduce the photoelectric conversion efficiency. In severe cases, this effect will cause the hot spot effect and affect the normal operation of the entire solar street light.

[0003] Chinese invention patent with the publication number of 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 with a support disk, and a counterweight is arranged inside the fixed platform; a connecting beam is fixedly connected to the front end surface of the support disk; mounting frames are fixedly connected to the ends of the two connecting beams away from the support disk; an electric telescopic rod I is fixedly connected inside the mounting frame; the annular jackets on both sides are placed outside the utility pole; then, control the telescopic end of the cylinder seat to drive the support disk to move upward. When the protection mechanism moves to the side close to the photovoltaic panel, stop the operation of the cylinder seat, and control the telescopic end of the electric telescopic rod I to move, so that its telescopic end drives the annular jacket to move towards the end of the utility pole. Under the clamping of the annular jackets on both sides, the stability of the protection mechanism during operation is improved, which is beneficial to the maintenance of the photovoltaic panel.

[0004] However, the above patent still has the following deficiencies in actual use: The patent drives the cleaning package to move on the surface of the photovoltaic panel through the electric telescopic rod III, and at the same time, cooperates with the water quality in the water suction pipe to moisten the cleaning package, so as to remove the stains on the surface of the photovoltaic panel. However, after the bird droppings adhere to the surface of the photovoltaic panel, with the passage of time, the hardness of the bird droppings will gradually increase. It is difficult to break the hard bird droppings only relying on the cleaning package made of sponge material. Although water can reduce the hardness of the bird droppings, the water will also be mixed with all the bird droppings powder, resulting in the water becoming sewage. Wiping the surface of the photovoltaic panel with the sewage 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 leads to a longer cleaning time for the surface of the photovoltaic panel, greatly reducing the cleaning efficiency of the surface of the photovoltaic panel. Summary of the Invention

The scraping component 52 and the cleaning component 53 are both connected to the switching component 54. The cleaning component 53 is communicated with the water pump 16 through a pipeline. An air drying component 6 is provided on the top of the vertical plate 141. The air drying component 6 is in transmission connection with the rotating mechanism 2. A collection box 7 is provided in the front of the vertical plate 141. A partition plate 71 is provided in the collection box 7. The partition plate 71 divides the interior of the collection box 7 into a sewage collection area 72 and an impurity collection area 73. A guiding plate 74 is provided above the partition plate 71. A plurality of water passing holes are provided on the guiding plate 74. A positioning mechanism 8 is provided directly below the collection box 7.

[0036] The present invention can move the bottom plate 1 to change the position of the entire device. The height of the stain cleaning mechanism 5 can be changed through the lifting ladder 11 until the height of the stain cleaning mechanism 5 is the same as that of the photovoltaic panel. The placement angle of the two cantilevers 3 can be changed through the rotating mechanism 2, that is, the clamping mechanism 4 also synchronously changes the placement angle, so that the surface of the photovoltaic panel at different placement angles can be cleaned of stains.

[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 a chain drive. The two cantilevers 3 are respectively connected to both sides of the synchronous shaft 23.

[0038] The first sprocket 24 is driven to rotate by rotating the motor 22. The first sprocket 24 drives the second sprocket 25 to rotate through a chain. The second sprocket 25 drives the synchronous shaft 23 to rotate synchronously. The synchronous shaft 23 drives the two cantilevers 3 and the clamping mechanism 4 to rotate synchronously, that is, the placement angle of the clamping mechanism 4 is changed. Then, the two sides of the photovoltaic panel are clamped by the clamping mechanism 4.

[0039] The clamping mechanism 4 includes two clamping assemblies. The two clamping assemblies are respectively arranged on the two cantilevers 3. Each clamping assembly includes a clamping electric push rod 41 and an L-shaped clamping frame 42. A telescopic groove 421 is formed on the side wall of the L-shaped clamping frame 42. A telescopic pressing frame 422 is slidably arranged in the telescopic groove 421. A plurality of springs 423 are arranged in the telescopic pressing frame 422. The clamping electric push rod 41 is horizontally connected to the side wall of the cantilever 3. The back of the L-shaped clamping frame 42 is fixedly connected to the output end of the clamping electric push rod 41. A suspension plate is arranged at the top of the L-shaped clamping frame 42. The moving electric cylinder 51 is arranged on the suspension plate.

[0040] The two clamping electric push rods 41 work synchronously to drive the corresponding L-shaped clamping frames 42 to move relatively. The telescopic pressing frame 422 can gradually abut against the side wall of the photovoltaic panel. The telescopic pressing frame 422 presses against the springs 423, and the springs 423 are compressed. The two L-shaped clamping frames 42 clamp the photovoltaic panel. The elastic force of the springs 423 enables the telescopic pressing frame 422 to tightly press against the side wall of the photovoltaic panel, improving the clamping and fixing stability of 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.

[0042] The scraping component 52 includes a scraping roller 521. A plurality of protrusions 522 are arranged on the scraping roller 521 at equal angles. The end of the protrusion 522 is provided with an arc surface. The cleaning component 53 includes a connecting pipe 531 and a sponge ring 532. A plurality of water permeable holes 533 are arranged on the connecting pipe 531. 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 component 54.

[0043] The switching component 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. A connecting rod 5412 is provided on the connecting plate 5411. A slider 5421 is slidably arranged 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 arranged 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 passing cavity 5434 is provided at one end of the V-shaped plate 5433. An inlet 5435 communicating with the water passing cavity 5434 is provided on the outer wall of the V-shaped plate 5433. An outlet 5436 communicating with the water passing cavity 5434 is provided on the side wall of the V-shaped plate 5433. The switching electric push rod 541, the sliding seat 542 and the second rotating seat 543 are arranged on the sliding table. The rack 5423 is engaged with the sector gear 5432. The connecting rod 5412 is fixedly connected with the slider 5421. The connecting pipe 531 is detachably connected to the outlet 5436. The inlet 5435 is communicated with the water pump 16 through a pipeline. The scraping roller 521 is connected to one end of the V-shaped plate 5433 far away from the connecting pipe 531. The scraping roller 521 and the connecting pipe 531 are parallel to each other.

[0044] By switching on the electric push rod 541 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 base 542, the slider 5421 drives the connecting seat 5422 and the rack 5423 to move synchronously, the rack 5423 drives the sector gear 5432 to rotate, the sector gear 5432 drives the rotating shaft 5431 to rotate synchronously, and the V-shaped plate 5433 rotates synchronously with the rotating shaft 5431. After that, the end of one of the protrusions 522 abuts against the surface of the photovoltaic panel. Then, the moving cylinder 51 drives its slide to move, and the slide drives the electric push rod 541, the slide base 542, the second rotating seat 543, and the V-shaped plate 5433 to move synchronously. The V-shaped plate 5433 drives the scraping roller 521 and the connecting pipe 531 to move synchronously. The scraping roller 521 moves synchronously with the V-shaped plate 5433. The protrusion 522 can crush the hard bird droppings. After the bird droppings are crushed, they can move synchronously with the protrusion 522. Then, the bird droppings can fall onto the guide plate 74. Then, the electric push rod 541 drives the slider 5421 to move in the reverse direction, and the protrusion 522 can move away from the surface of the photovoltaic panel. Immediately afterwards, the moving cylinder 51 drives the V-shaped plate 5433 to return to the initial position. Then, the electric push rod 541 drives the slider 5421 to continue moving in the reverse direction, and the sponge ring 532 abuts against the surface of the photovoltaic panel. Subsequently, the water pump 16 works to transport the water in the water tank 15 into the water cavity, and the water can enter the connecting pipe 531. Then, the water seeps into the sponge ring 532 through the water permeable holes 533. Immediately afterwards, the moving 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. 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 onto the guide plate 74, so that the stains on the surface of the photovoltaic panel can be completely removed.

[0045] Preferably, the ends of the scraping roller 521 and the connecting pipe 531 of one of the stain cleaning mechanisms 5 are both provided with an embedded positioning groove 523, and the ends of the scraping roller 521 and the connecting pipe 531 of the other stain cleaning mechanism 5 are both 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 enables the scraping roller 521 and the connecting pipe 531 of the stain cleaning mechanism 5 to complete a 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 it is 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, a drying component 6 is provided to clean the water stains. The drying component 6 includes a blower 61, a blowing hood 62 and two third rotating seats 63. Connecting shafts are provided on both sides of the blowing hood 62. A third sprocket 621 is provided on one of the connecting shafts, and a fourth sprocket 231 is provided on the synchronous shaft 23. The blower 61 is arranged on the top of the top plate 14. The two third rotating seats 63 are symmetrically arranged on the top of the vertical plate 141. The blowing hood 62 is rotatably arranged on the two third rotating seats 63 through the connecting shafts. The blowing hood 62 is communicated with the blower 61 through a pipeline. The third sprocket 621 and the fourth sprocket 231 are connected by a chain drive.

[0047] The blower 61 generates wind power, and then the wind power is conveyed into the blowing hood 62 through the pipeline. The blowing hood 62 guides the wind power onto the surface of the photovoltaic panel. Then the water stains can be dried by the wind. Through the cooperation of the third sprocket 621, the fourth sprocket 231 and the chain, the blowing hood 62 can rotate synchronously with the cantilever 3, so that the air outlet of the blowing hood 62 can always face the surface of the photovoltaic panel.

[0048] After the sewage and the crushed bird droppings fall onto the guiding plate 74, the sewage can guide the water into the sewage collection area 72 through the water passing holes. The water passing holes can screen out the impurities in the sewage. The crushed bird droppings can flow along the guiding plate 74 into the impurity collection area 73, so as to realize the automatic collection of sewage and impurities and avoid the sewage and impurities falling to the ground to cause pollution.

[0049] Furthermore, shaking shafts 741 are provided on both sides of the tail end of the guiding plate 74. A shaking motor 75 is installed on one side side wall of the collecting box 7. A rotating rod 751 is installed on the shaking motor 75. A resisting ball 752 is installed at the end of the rotating rod 751. The resisting ball 752 abuts against the bottom of the head end of the guiding plate 74. A buffer inclined plate 742 is provided at the top of the guiding 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 .
