Description

Technical Field

[0001] The invention relates to the technical field of curtain wall cleaning, in particular to a photovoltaic glass curtain wall cleaning device. Background Art

[0002] With the increasing depletion of fossil fuels and the deteriorating human living environment, countries around the world are increasingly supporting clean energy sources such as solar power, wind power, and other renewable energy sources. Building-integrated photovoltaic (BIPV) buildings are the photovoltaic application most closely aligned with human life, perfectly embodying the concept of green energy conservation and environmental protection. BIPV is a technology that integrates or incorporates solar power generation (PV) products into buildings. The PV system integrated into a building can function as a standalone power source or be connected to the grid. With the national goal of achieving carbon peak and carbon neutrality, the development of green buildings that promote energy conservation and emission reduction will become a general trend.

[0003] Photovoltaic curtain walls fully embody the intelligent and user-friendly features of architecture. Essentially, they are curtain walls that convert solar energy into electricity. When photovoltaics are integrated into architecture, buildings become capable of generating their own electricity. Photovoltaic glass curtain walls are designed, constructed, and installed simultaneously with the building, providing electricity while also creating a modern aesthetic and a sense of technology. However, dust accumulation on photovoltaic glass curtain walls during use can be difficult to clean, and this accumulation reduces the efficiency of the photovoltaic power station. Manual cleaning is time-consuming and involves working at height, which can be dangerous.

[0004] However, the existing equipment for cleaning photovoltaic glass curtain walls has the following problems when cleaning photovoltaic glass curtain walls: 1. Existing equipment for cleaning photovoltaic glass curtain walls mostly uses soft rags or sponges to wipe the surface of photovoltaic glass curtain walls, and the stains and moisture on the soft rags or sponges will gradually increase during use. After a certain degree of use, they cannot self-clean, and the cleaning effect gradually deteriorates in the later period; 2. After the existing equipment for cleaning photovoltaic glass curtain walls uses cleaning fluid to clean the photovoltaic glass curtain wall, the surface of the photovoltaic glass curtain wall cannot be dried in time, and the wet glass surface is more likely to absorb and stick to dust in the air, thereby reducing the cleaning effect.

DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] See Figure 1 As shown, a photovoltaic glass curtain wall cleaning device includes a lifting and traveling mechanism 1, a shell 2, a pressing mechanism 3, a wiping mechanism 4, a cleaning mechanism 5 and a spraying mechanism 6, characterized in that: the lifting and traveling mechanism 1 is connected to both sides of the shell 2 by a safety rope, the shell 2 is a box-shaped structure with one end open, the pressing mechanism 3 is arranged on the upper side of the shell 2, the wiping mechanism 4 is arranged in the middle of the shell 2, the cleaning mechanism 5 is arranged on the shell 2 below the wiping mechanism 4, and the spraying mechanism 6 is arranged on the shell 2 below the cleaning mechanism 5;

[0033] During specific operation, the lifting and traveling mechanism 1 is at a suitable position on the top of the building where the photovoltaic glass curtain wall is installed. The outer shell 2 is suspended on the outside of the building by a safety rope, and the open side of the outer shell 2 faces the photovoltaic glass curtain wall. The lifting by the safety rope greatly reduces the safety risk.

[0034] See Figure 1 As shown, the lifting and traveling mechanism 1 includes a traveling trolley 11, a dual-axis motor 12, a winding disk 13, a first electric push rod 14, and a guide wheel 15. The dual-axis motor 12 is mounted on the upper end of the traveling trolley 11 through a motor mounting seat. Winding disks 13 are mounted on the output shafts on both sides of the dual-axis motor 12. A safety rope is wound inside the winding disk 13. The first electric push rod 14 is symmetrically arranged on a vertical surface on one side of the traveling trolley 11. The telescopic end of the first electric push rod 14 is provided with a guide wheel 15. The outer circumference of the guide wheel 15 is provided with a groove. The end of the safety rope passes through the groove of the guide wheel 15 and is fixed to both sides of the housing 2. The two strands of safety rope can provide a stabilizing force to the housing 2, which also helps to maintain the stability of the housing 2.

[0035] During specific operation, the horizontal position of the shell 2 is adjusted by the lateral movement of the walking trolley 11, and the telescopic rod of the No. 1 electric push rod 14 is extended and retracted to drive the guide wheel 15 to move, so that the guide wheel 15 pushes the safety rope and drives the shell 2 close to the glass surface, and the dual-axis motor 12 works. The output shaft of the dual-axis motor 12 rotates to drive the winding disk 13 to rotate, and the winding disk 13 lowers the safety rope to make the shell gradually move downward. At the same time, the clamping mechanism 3, wiping mechanism 4, cleaning mechanism 5 and spraying mechanism 6 on the shell work to clean the photovoltaic glass curtain wall.

[0036] See Figure 1 and Figure 2As shown, the pressing mechanism 3 includes a ventilation slot 31, a mounting bracket 32, a brushless motor 33 and a fan blade 34. The ventilation slot 31 is opened at the end of the housing 2 away from the opening, and there are four ventilation slots 31 and they are evenly arranged. The mounting bracket 32 ​​is symmetrically arranged on the housing 2 corresponding to the ventilation slots 31. The brushless motor 33 is arranged on the mounting bracket 32 ​​and corresponds one-to-one with the ventilation slots 31. The fan blade 34 is installed on the output shaft of the brushless motor 33.

[0037] The housing 2 has an air inlet 21 at a fixed portion, a filter 22 is provided in the air inlet 21, and a plurality of heating plates 23 are obliquely provided in the housing below the filter 22. Spring rods 24 are provided at the four corners of the outer wall of the housing 2, and travel wheels 25 are provided at the ends of the spring rods 24.

[0038] During specific operation, the brushless motor 33 works, and the output shaft of the brushless motor 33 drives the fan blades 34 to rotate at high speed to inhale air into the outer shell 2. Since the open end of the outer shell 2 is close to the photovoltaic glass curtain wall and the air intake volume is small, the outer shell 2 is in a certain negative pressure state, so the open end of the outer shell 2 is pressed against the photovoltaic glass curtain wall, and the walking wheel 25 is against the photovoltaic glass curtain wall. Under the action of the elastic supporting force of the spring rod 24, the contact and friction between the outer shell 2 and the photovoltaic glass curtain wall are prevented. At this time, the wiping mechanism 4 and the cleaning mechanism 5 in the outer shell 2 are close to the surface of the photovoltaic glass curtain wall, so that the wiping mechanism 4 and the cleaning mechanism 5 can clean the surface of the photovoltaic glass curtain wall efficiently, and the pressing force between the wiping mechanism 4 and the cleaning mechanism 5 and the surface of the photovoltaic glass curtain wall can be controlled by controlling the rotation speed of the output shaft of the brushless motor 33, which has the advantages of wide range of use and stable operation.

[0039] See Figure 2 As shown, the spray mechanism 6 includes a connecting box 61, an atomizing nozzle 62, a water tank 63 and a water pump 64. The connecting box 61 is a hollow structure. The atomizing nozzle 62 is evenly and linearly arranged on one side of the connecting box 61 close to the opening of the shell 2. The atomizing nozzle 62 is connected to the inside of the connecting box 61. The water tank 63 is installed in the shell 2 and close to the connecting box 61. The water tank 63 stores cleaning liquid. A water pump 64 is provided between the water tank 63 and the connecting box 61. The water outlet of the water pump 64 is connected to the inside of the connecting box 61, and the water inlet of the water pump 64 is connected to the inside of the water tank 63.

[0040] During specific operation, the shell 2 moves downward along the photovoltaic glass curtain wall under the cooperation of the lifting and traveling mechanism 1 and the clamping mechanism 3. During the downward movement, the water pump 64 draws the cleaning liquid in the water tank 63 into the connecting box 61, so that the pressure in the connecting box 61 increases, and the cleaning liquid is sprayed out in a mist form to the surface of the photovoltaic glass curtain wall through the atomizing nozzle 62. This mechanism can evenly spray the cleaning liquid to the surface of the photovoltaic glass curtain wall, preventing a certain part of the surface of the photovoltaic glass curtain wall from having a poor cleaning effect due to lack of cleaning liquid.

[0041] See Figure 1 and Figure 2 As shown, the cleaning mechanism 5 includes a No. 2 mounting box 51, a rotating shaft 52, a rotating motor 53, a driving bevel gear 54, a rotating rod 55, a driven bevel gear 56 and a cleaning brush 57. The No. 2 mounting box 51 is installed between the inner walls of the housing 2 on the lower side of the wiping mechanism 4, and the rotating shaft 52 is rotatably connected to the No. 2 mounting box 51. A rotating motor 53 is provided on the outer side of the housing 2 corresponding to the No. 2 mounting box 51. The output shaft of the rotating motor 53 passes through the side wall of the housing 2 and is connected to the rotating shaft 52. The driving bevel gear 54 is evenly arranged in a straight line on the rotating shaft 52. A rotating rod 55 is evenly arranged on one side of the No. 2 mounting box 51 close to the opening of the housing 2. One end of the rotating rod 55 in the No. 2 mounting box 51 is fixedly connected to the driven bevel gear 56, and the driven bevel gear 56 is meshed with the driving bevel gear 54 in a one-to-one correspondence. A cleaning brush 57 is fixedly connected to one end of the rotating rod 55 outside the No. 2 mounting box 51.

[0042] During specific operation, after the spraying mechanism 6 sprays the cleaning liquid onto the surface of the photovoltaic glass curtain wall, the cleaning mechanism 5 continues to move downward with the outer shell. During the movement, the rotating motor 53 works, and the output shaft of the rotating motor 53 rotates to drive the rotating shaft 52 to rotate. The rotation of the rotating shaft 52 drives the driving bevel gear 54 to rotate, and the rotation of the driving bevel gear 54 drives the driven bevel gear 56 to rotate, so that the driven bevel gear 56 drives the cleaning brush 57 to rotate through the rotating rod 55. The cleaning brush 57 brushes the surface of the photovoltaic glass curtain wall, thereby brushing away the stains and dust on the surface of the photovoltaic glass curtain wall, with high cleaning efficiency.

[0043] See Figure 1 and Figure 2 As shown, the wiping mechanism 4 includes a No. 1 drive branch chain 41, a wiping roller 42, a guide plate 43, an arc plate 44, a sealing branch chain 45, a No. 2 drive branch chain 46 and a switching branch chain 47. The No. 1 drive branch chain 41 is arranged on both sides of the shell 2 and is installed symmetrically. The two ends of the wiping roller 42 are connected between the No. 1 drive branch chain 41. The guide plate 43 is obliquely arranged between the inner walls of the shell 2 on the lower side of the wiping roller 42. The lower end of the guide plate 43 is connected to the arc plate 44, and a plurality of water leakage holes are opened at the bottom of the arc plate 44. A sealing branch chain 45 is arranged on the side wall of the shell 2 near the arc plate 44. The No. 2 drive branch chain 46 is arranged on the shell 2 at both ends of the arc plate 44. The switching branch chain 47 is arranged on the shell 2 on the upper side of the sealing branch chain 45.

[0044] See Figure 2As shown, the wiping roller 42 includes a rotating shaft 421, absorbent cotton 422, wiping cotton 423 and a conical groove 424. The outer wall of the rotating shaft 421 is wrapped with cylindrical absorbent cotton 422, and the outer wall of the absorbent cotton 422 is evenly provided with wiping cotton 423. The conical groove 424 is opened at both ends of the rotating shaft 421. When working, the No. 1 drive branch chain 41 drives the rotating shaft 421, the absorbent cotton 422 and the wiping cotton 423 to rotate, and the surface of the photovoltaic glass curtain wall is wiped by the wiping cotton 423. The absorbent cotton 422 and the wiping cotton 423 have a certain softness, which makes it difficult to scratch the photovoltaic glass curtain wall. At the same time, it can increase the contact area and improve the wiping and cleaning effect. Moreover, the absorbent cotton 422 and the wiping cotton 423 have good water absorption, which can greatly increase the service life of the wiping roller 42.

[0045] During specific operation, the wiping roller 42 is driven to rotate by the No. 1 driving branch chain 41, and the wiping roller 42 wipes the surface of the photovoltaic glass curtain wall, and absorbs and wipes away the stains and dust cleaned by the cleaning mechanism 5 and the residual cleaning liquid. When the wiping roller 42 is used to a certain extent, the wiping and cleaning effect of the wiping roller 42 is greatly reduced due to its absorption of too much stains, dust and cleaning liquid. At this time, the wiping roller 42 is removed from the No. 1 driving branch chain 41 and clamped between the No. 2 driving branch chain 46 by switching the branch chain 47. The sealing branch chain 45 works and forms a sealing structure between the guide plate 43 and the arc plate 44. Then the No. 2 driving branch chain 46 drives the wiping roller 42 to rotate at high speed, so that the wiping roller 42 The adsorbed cleaning liquid is thrown out, and at the same time, the cleaning liquid can also take away most of the stains and dust. The thrown cleaning liquid leaks out from the leaking hole. After the water on the wiping roller 42 is dried, the No. 1 drive branch chain 41 stops working, and the sealing branch chain 45 returns to the initial state. Then, the wiping roller 42 is removed from between the No. 2 drive branch chain 46 and clamped between the No. 1 drive branch chain 41 by switching the branch chain 47. The No. 1 drive branch chain 41 continues to drive the wiping roller 42 to rotate and wipe the surface of the photovoltaic glass curtain wall. This mechanism avoids the need to retract the equipment to the roof to replace the wiping roller 42, thereby realizing self-cleaning of the wiping roller 42, saving working time, and ensuring that the wiping roller 42 has a good cleaning effect from the start to the end of the working period. When the pressing mechanism 3 is working, a certain amount of air enters the outer shell 2 from the air inlet 21. The filter 22 can prevent larger particles from entering the outer shell. The air is heated to a suitable temperature when passing through the heating plate 23. The heating plate 23 is tilted and has a guiding effect, so that the heated air passes through the surface of the photovoltaic glass curtain wall after being wiped by the wiping roller 42, thereby drying the residual moisture on the surface of the photovoltaic glass curtain wall, preventing moisture from remaining, causing the surface of the photovoltaic glass curtain wall that has not been dried in time to re-absorb dust, thereby further improving the cleaning effect.

[0046] See Figure 3As shown, the No. 1 driving branch chain 41 includes a driving motor 411, a sliding groove 412, a top pressure block 413, a telescopic groove 414, a limiting groove 415, an anti-rotation block 416 and a spring 417. The driving motor 411 is arranged on both sides of the shell 2 and is symmetrically installed, and the output shaft of the driving motor 411 passes through the shell 2. A sliding groove 412 is provided on the inner wall of the shell 2 at a position corresponding to the driving motor 411. One end of the top pressure block 413 is conical, and the other end of the top pressure block 413 slides with the sliding groove 412. A telescopic groove 414 is provided at one end of the top pressure block 413 in the sliding groove 412, and a limiting groove 415 is provided. The output shaft of the drive motor 411 is provided in the telescopic slot 414, and the output shaft of the drive motor 411 is slidably matched with the telescopic slot 414. An anti-rotation block 416 that slidably matches the limit slot 415 is provided on the output shaft of the drive motor 411. The end of the output shaft of the drive motor 411 is connected to the telescopic slot 414 through a spring 417. A protrusion is provided on the outer wall of one conical end of the top pressure block 413, and a groove that cooperates with the protrusion is provided on the inner wall of the conical slot 424. It can prevent relative rotation between the wiping roller 42 and the top pressure block 413, thereby increasing the working stability. The structural principle of the No. 2 drive branch chain 46 is the same as that of the No. 1 drive branch chain 41.

[0047] See Figure 2 As shown, the switching branch chain 47 includes a No. 2 electric push rod 471, a No. 3 electric push rod 472, a mounting rod 473 and a U-shaped clamping sleeve 474. The end of the No. 2 electric push rod 471 away from the telescopic rod is hinged on the inner wall of the shell 2. A through slot is opened in the middle of the shell 2. The No. 3 electric push rod 472 is hinged between the through slots, and the telescopic rod end of the No. 3 electric push rod 472 is hinged to the end of the No. 2 electric push rod 471 body close to the telescopic rod. The telescopic rod end of the No. 2 electric push rod 471 is provided with a mounting rod 473, and U-shaped clamping sleeves 474 are provided at both ends of the mounting rod 473.

[0048] During specific operation, the driving motor 411 works, and the output shaft of the driving motor 411 rotates to drive the top pressure block 413 to rotate. The rotation of the top pressure block 413 drives the wiping roller 42 to rotate to wipe the surface of the photovoltaic glass curtain wall. In the process of switching the branch chain 47 to remove the wiping roller 42, the telescopic rod of the No. 2 electric push rod 471 extends to drive the No. 3 electric push rod 472 to deflect toward the wiping roller 42 between the No. 1 driving branch chain 41. The telescopic rod of the No. 3 electric push rod 472 extends and drives a U-shaped sleeve 474 to press against the wiping roller 42 through the mounting rod 473. The U-shaped sleeve 474 is sleeved on the wiping roller 42. At this time, the telescopic rod of the No. 3 electric push rod 472 stops extending, and the telescopic rod of the No. 2 electric push rod 471 retracts The return causes the No. 3 electric push rod 472 to deflect and reset, and at the same time, the U-shaped sleeve 474 pulls the wiping roller 42, and the conical groove 424 on the wiping roller 42 squeezes the conical end of the top pressure block 413, causing the top pressure block 413 to shrink into the sliding groove 412, and the spring 417 is compressed, so that the two opposite top pressure blocks 413 move away from each other, causing the wiping roller 42 to disengage from between the top pressure blocks 413, and the telescopic rod of the No. 2 electric push rod 471 continues to retract. At the same time, the telescopic rod of the No. 3 electric push rod 472 is extended to drive the wiping roller 42 along the guide plate 43 to move toward the No. 2 drive branch chain 46. The wiping roller 42 is squeezed between the top pressure blocks 413 on the No. 2 drive branch chain 46, and the telescopic rod of the No. 3 electric push rod 472 is retracted.

The No. 1 installation box 451 is arranged on the outer wall of the housing 2 near the guide plate 43, the winding motor 452 is arranged at one end of the No. 1 installation box 451, the winding shaft 453 is rotatably connected to the No. 1 installation box 451, and the output shaft of the winding motor 452 is connected to the winding shaft 453, the sealing soft plate 454 is wound on the winding shaft 453, and the guide frame 455 is provided with a plurality of guide grooves 456. The frame 455 is arc-shaped and its two ends are interconnected. The guide frame 455 is connected to the inner part of the No. 1 installation box 451. One end of the guide frame 455 is connected to the outer shell 2 and an arc-shaped matching groove is provided at a position corresponding to the outer shell 2. Arc-shaped guide grooves 456 are provided on both sides of the inner wall of the outer shell 2. An integral arc is formed between the guide frame 455, the guide groove 456 and the matching groove. The free end of the sealing soft board 454 slides with the guide frame 455, the guide groove 456 and the matching groove, and one end of the guide groove 456 is close to the guide plate 43.

[0050] During specific operation, the winding motor 452 works, and the output shaft of the winding motor 452 rotates to drive the winding shaft 453 to rotate, so that the free end of the sealing soft plate 454 extends along the direction of the guide frame 455, the guide groove 456 and the matching groove, until the free end of the sealing soft plate 454 presses against the guide plate 43, so that the wiping roller 42 is in a sealed state, preventing the cleaning liquid adsorbed in the wiping roller 42 from splashing when it is thrown out, and also facilitating the recovery of the cleaning liquid. After the wiping roller 42 is dried, the sealing branch chain 45 returns to its initial state, and by switching the No. 2 electric push rod 471 and the No. 3 electric push rod 472 in the branch chain 47 to work in the opposite direction of the above, the wiping roller 42 is re-clamped between the No. 1 drive branch chain 41.
