Description

Technical Field

[0001] The present invention relates to the field of photovoltaic glass, and in particular to a self-cleaning solar photovoltaic glass and a method thereof. Background Art

[0002] The main function of photovoltaic glass is to serve as the outermost light-transmitting encapsulation panel of a photovoltaic module, and it has high requirements in terms of light transmittance, high temperature resistance, oxidation resistance, corrosion resistance, etc., which directly affect the power generation efficiency and service life of the module;

[0003] After long-term outdoor use of photovoltaic glass, some dust or impurities will accumulate on the surface of the photovoltaic glass. The accumulation of dust or impurities will affect the absorption effect of the photovoltaic glass on sunlight, and thus affect the use of the photovoltaic glass. Traditional cleaning methods are all carried out manually, which has low cleaning efficiency. Moreover, in snowy weather, snow will accumulate on the surface of the main body of the photovoltaic glass and it takes many days to be removed by sunlight irradiation, which reduces the use efficiency of the photovoltaic glass.

The rolling shutter storage frame is installed with the photovoltaic glass installation frame through a support rod. A rolling shutter motor is fixedly installed on the outer wall of the rolling shutter storage frame. The output end of the rolling shutter motor is installed with a winding roller in the rolling shutter storage frame. The rolling shutter is wound on the winding roller. A slider is arranged at the front end of the bottom of the rolling shutter and moves in a corresponding guide groove opened on the top of the guide strip. The guide strip is installed on the top of the photovoltaic glass installation frame.

[0010] Preferably, the lifting mechanism includes a first servo motor fixedly installed on the top of a support column. The output end of the first servo motor is connected with one end of a first lead screw. The other end of the first lead screw is installed with a bearing seat installed at the inner bottom of a groove wall through a bearing.

[0014] A method for self-cleaning solar photovoltaic glass includes the following steps:

[0015] S1. The second servo motor on the first fixing block works to drive the second lead screw to rotate. While the second lead screw rotates, the sleeve block will move accordingly, thereby driving the support bar to move outwards from the storage box. Water in the water supply pipe will be sprayed out from the spray heads at the bottom of the spray pipe to wash the surface of the photovoltaic glass main body. At the same time, the cleaning sponge block wipes the surface of the photovoltaic glass main body back and forth to enhance the cleaning effect of the photovoltaic glass main body. When it is necessary to replace the cleaning sponge block at the bottom of the support bar, multiple stacked cleaning sponge blocks are stored in the storage box. The support bar will be stored in the storage box under the rotation of the second lead screw and be adapted to the position of the support plate stored in the storage box. At this time, the output end of the electric cylinder on the clamping block retracts, and the cleaning sponge block will fall off. Then the first cylinder works to drive the fixed bar to move, and the push block on the fixed bar will slowly push out the cleaning sponge block located on the support plate and place it between the two clamping blocks at the bottom of the support bar. And the electric cylinder works again to clamp the cleaning sponge block, completing the replacement of the cleaning sponge block;

[0016] S2. When protection work needs to be carried out on the main body of the photovoltaic glass, the rolling gate motor on one side of the rolling gate plate storage frame in the protection mechanism operates, driving the winding roller in the rolling gate plate storage frame to rotate in the reverse direction. As a result, the rolling gate plate slowly moves forward on the guide strip, and the rolling gate plate will cover the upper position of the main body of the photovoltaic glass to carry out protection work on the main body of the photovoltaic glass;

[0017] S3. When adjusting the height position of the main body of the photovoltaic glass, the first servo motor on the support column 2 in the lifting mechanism operates, driving the mounting seat to move upward. At the same time, the tooth seat moves upward in the guide seat. After the main body of the photovoltaic glass is adjusted to a suitable position, the third cylinder operates, driving the clamping tooth block on one side of the clamping block to insert into the corresponding tooth groove on the tooth seat to limit and fix the tooth seat.

[0018] In summary, the present invention includes the following beneficial technical effects:

[0019] In the cleaning mechanism of the present invention, a storage box is provided, and an automatic replacement component is provided in the storage box. When it is necessary to replace the cleaning sponge block at the bottom of the support bar in the cleaning mechanism, the support bar will be stored in the storage box, and the cleaning sponge block at the bottom of the support bar is adapted to the position of the support plate in the storage box. Then the electric cylinder will loosen, and the cleaning sponge block at the bottom of the support bar will fall off. At this time, the first cylinder operates, driving the push block to move, moving the cleaning sponge block stacked on the support plate in the storage box forward and placing it at the clamping block at the bottom of the support bar. The electric cylinder operates again, and the output end of the electric cylinder will insert into the corresponding through hole on the cleaning sponge block to fix the cleaning sponge block, making the replacement more convenient and improving the cleaning efficiency and quality of the photovoltaic glass;

[0020] The present invention is provided with a protection mechanism. In the protection mechanism, a rolling gate plate storage frame is provided.

Detailed implementation manners

[0032] The following further elaborates on the present invention in conjunction with the attached Figures 1 - 9 drawings.

[0033] An embodiment of the present invention discloses a self-cleaning solar photovoltaic glass, which includes a support base 1. L-shaped bottom blocks 5 are arranged on both sides of the support base 1. Support columns 2 are fixedly installed at the four corners on the top of the support base 1. A lifting mechanism is fixedly installed on the support columns 2, and the lifting mechanism drives the mounting seat 6 to move up and down. A support mechanism is fixedly installed on the top of the support base 1, and the support mechanism supports the mounting seat 6. An angle adjustment mechanism is fixedly installed on the top of the mounting seat 6, and the angle adjustment mechanism is fixedly installed with the photovoltaic glass installation frame 7. The photovoltaic glass installation frame 7 installs the photovoltaic glass main body 8. One end of the photovoltaic glass installation frame 7 is installed with a protection mechanism through a support rod, and the other end of the photovoltaic glass installation frame 7 is installed with a cleaning mechanism through a support rod. An automatic replacement component for replacing the cleaning sponge block 23 at the bottom of the support bar 16 is arranged in the cleaning mechanism;

[0034] The cleaning mechanism includes two first fixing blocks 18 installed on one side wall of the photovoltaic glass installation frame 7. A second servo motor 19 is installed on one of the first fixing blocks 18. The output end of the second servo motor 19 is installed with one end of a second lead screw 20, and the other end of the second lead screw 20 is installed with a bearing seat installed on the other first fixing block 18 through a bearing. The second lead screw 20 is also adaptively installed with a lead screw sleeve block 21. Two convex blocks are fixedly installed on the other side wall of the photovoltaic glass installation frame 7. A guide rod 32 is fixedly installed between the two convex blocks. A guide block 33 for moving is arranged on the guide rod 32. The tops of the guide block 33 and the lead screw sleeve block 21 are installed with a support bar 16 through a support rod. Two clamping blocks 17 are arranged at the bottom of the support bar 16. An electric cylinder 34 is fixedly installed on the two clamping blocks 17. The output end of the electric cylinder 34 is inserted into a through hole opened on the end wall of the cleaning sponge block 23. One side of the support bar 16 is fixedly installed with a water spray pipe 22 through a support rod. A plurality of water spray heads 28 are arranged at the bottom of the water spray pipe 22. The water inlet of the water spray pipe 22 is installed with a tap water pipe through a hose. The second servo motor 19 on the first fixing block 18 works to drive the second lead screw 20 to rotate. While the second lead screw 20 rotates, the lead screw sleeve block 21 will move accordingly, thereby driving the support bar 16 to move outwards from the storage box 14. Water in the tap water pipe will be sprayed out from the water spray heads 28 at the bottom of the water spray pipe 22 to wash the surface of the photovoltaic glass main body 8. At the same time, the cleaning sponge block 23 scrubs the surface of the photovoltaic glass main body 8 back and forth to increase the cleaning effect on the photovoltaic glass main body 8.

[0035] The automatic replacement component includes a storage box 14. On the inner side wall of the storage box 14, there are limiting bars 27. Between the two limiting bars 27, a limiting groove 30 is formed. Multiple cleaning sponge blocks 23 are stacked in the limiting groove 30. On the outer wall of the storage box 14, a first cylinder 24 is fixedly installed. The output end of the first cylinder 24 is installed with a fixed bar 25. One side of the fixed bar 25 is connected to a push block 26 through a support rod. An opening slot 15 is formed on the side wall of the storage box 14. When it is necessary to replace the cleaning sponge block 23 at the bottom of the support bar 16, there are multiple stacked cleaning sponge blocks 23 stored in the storage box 14. The support bar 16 will be stored in the storage box 14 under the rotation of the second lead screw 20, adapting to the position of the support plate 31 stored in the storage box 14. At this time, the output end of the electric cylinder 34 on the clamping block 17 retracts, and the cleaning sponge block 23 will fall off. Then the first cylinder 24 works, driving the fixed bar 25 to move. The push block 26 on the fixed bar 25 will slowly push out the cleaning sponge block 23 located on the support plate 31 and place it between the two clamping blocks 17 at the bottom of the support bar 16. And the electric cylinder 34 works again to clamp the cleaning sponge block 23, completing the replacement of the cleaning sponge block 23.

[0036] Refer to Figure 1 , Figure 3 and Figure 4 , the protection mechanism includes a rolling shutter box 9. The rolling shutter box 9 is installed with the photovoltaic glass installation frame 7 through a support rod. On the outer wall of the rolling shutter box 9, a rolling shutter motor 11 is fixedly installed. The output end of the rolling shutter motor 11 is installed with a winding roller in the rolling shutter box 9. The rolling shutter plate 12 is wound on the winding roller. At the front end of the bottom of the rolling shutter plate 12, there is a slider, and the slider moves in the corresponding guide groove 13 opened on the top of the guide bar 10. The guide bar 10 is installed on the top of the photovoltaic glass installation frame 7. When it is necessary to protect the photovoltaic glass main body 8, the rolling shutter motor 11 located on one side of the rolling shutter box 9 in the protection mechanism works, driving the winding roller in the rolling shutter box 9 to rotate in the reverse direction. Thus, the rolling shutter plate 12 slowly moves forward on the guide bar 10, and the rolling shutter plate 12 will cover the upper position of the photovoltaic glass main body 8 to protect the photovoltaic glass main body 8.

[0037] Refer to Figure 1 , Figure 2 and Figure 6, the lifting mechanism includes a first servo motor 3 fixedly installed at the top of the support column 2. The output end of the first servo motor 3 is connected to one end of a first lead screw 4. The other end of the first lead screw 4 is installed through a bearing on a bearing seat installed at the inner bottom of the groove wall. The first lead screw 4 is also adaptively installed with a second lead screw sleeve seat, and the second lead screw sleeve seat is fixedly installed on the mounting seat 6. When adjusting the height position of the main body 8 of the photovoltaic glass, the first servo motor 3 on the support column 2 in the lifting mechanism works to drive the mounting seat 6 to move upward. At the same time, the tooth seat 46 moves upward in the guide seat 45. After the main body 8 of the photovoltaic glass is adjusted to a suitable position, the third cylinder 48 works to drive the clamping tooth block 50 on one side of the clamping block 49 to insert into the corresponding tooth groove on the tooth seat 46 to limit and fix the tooth seat 46.

[0038] Refer to Figure 1 , Figure 2 , Figure 5 and Figure 7 , the angle adjustment mechanism includes a fixed seat 35 and a driving motor 36 fixedly installed at the top of the mounting seat 6. The output end of the driving motor 36 is fixedly installed with a driving gear 37. The driving gear 37 is meshingly installed with a driven gear 38. A shaft rod is fixedly connected to the driven gear 38, and one end of the shaft rod passes through the fixed seat 35 and is fixedly installed with a limit gear 44. A connecting seat 39 is fixedly installed on the shaft rod. The top of the connecting seat 39 is fixedly installed with the photovoltaic glass installation frame 7. A limit component for limiting and fixing the limit gear 44 is fixedly installed on the outer wall of the mounting seat 6. The limit component includes a connecting block 40 fixedly installed on the fixed seat 35. A second cylinder 41 is fixedly installed on the connecting block 40. The output end of the second cylinder 41 is installed with a limit block 42. A limit tooth block 43 is provided on the limit block 42, and the limit tooth block 43 is inserted into the corresponding tooth groove on the limit gear 44. When it is necessary to adjust the angle of the photovoltaic glass installation frame 7, the driving motor 36 at the fixed seat 35 works to drive the driving gear 37 to rotate. While the driving gear 37 rotates, the connecting seat 39 will rotate accordingly. After the photovoltaic glass installation frame 7 is adjusted to a suitable angle, the driving motor 36 stops working. The second cylinder 41 on the fixed seat 35 works to drive the limit block 42 to move, so that the limit tooth block 43 on the limit block 42 is inserted into the corresponding tooth groove on the limit gear 44 to play a role in limiting and fixing the limit gear 44.

[0039] Refer to Figure 1, the support mechanism includes a guide seat 45 fixedly installed on the top of the support base 1. A moving tooth seat 46 is arranged in the inner cavity of the guide seat 45. The top of the tooth seat 46 is installed with the mounting seat 6. An L-shaped seat 47 is fixedly installed on one side wall of the guide seat 45. A third cylinder 48 is fixedly installed on the L-shaped seat 47. The output end of the third cylinder 48 is fixedly installed with a clamping block 49. A clamping tooth block 50 is arranged on one side of the clamping block 49. The clamping tooth block 50 is inserted into the corresponding tooth groove on the tooth seat 46.

[0040] A method for self-cleaning solar photovoltaic glass includes the following steps:

[0041] S1. The second servo motor 19 on the first fixed block 18 works to drive the second lead screw 20 to rotate. While the second lead screw 20 rotates, the sleeve block 21 will move accordingly, thereby driving the support bar 16 to move outwards from the storage box 14. Water in the water supply pipe will be sprayed out from the spray head 28 at the bottom of the spray pipe 22 to wash the surface of the photovoltaic glass main body 8. At the same time, the cleaning sponge block 23 scrubs the surface of the photovoltaic glass main body 8 back and forth to enhance the cleaning effect on the photovoltaic glass main body 8. When it is necessary to replace the cleaning sponge block 23 at the bottom of the support bar 16, multiple stacked cleaning sponge blocks 23 are stored in the storage box 14. The support bar 16 will be stored in the storage box 14 under the rotation of the second lead screw 20, adapting to the position of the support plate 31 stored in the storage box 14. At this time, the output end of the electric cylinder 34 on the clamping block 17 retracts, and the cleaning sponge block 23 will fall off. Then, the first cylinder 24 works to drive the fixed bar 25 to move. The push block 26 on the fixed bar 25 will slowly push out the cleaning sponge block 23 located on the support plate 31 and place it between the two clamping blocks 17 at the bottom of the support bar 16. And the electric cylinder 34 works again to clamp the cleaning sponge block 23 to complete the replacement of the cleaning sponge block 23;

[0042] S2. When it is necessary to protect the photovoltaic glass main body 8, the rolling gate motor 11 located on one side of the rolling gate plate storage frame 9 in the protection mechanism works to drive the winding roller in the rolling gate plate storage frame 9 to rotate in the reverse direction. As a result, the rolling gate plate 12 will slowly move forward on the guide bar 10, and the rolling gate plate 12 will cover the upper position of the photovoltaic glass main body 8 to protect the photovoltaic glass main body 8;

[0043] S3. When adjusting the height position of the photovoltaic glass main body 8, the first servo motor 3 on the support column 2 in the lifting mechanism works to drive the mounting seat 6 to move upward. At the same time, the tooth seat 46 moves upward in the guide seat 45. After the photovoltaic glass main body 8 is adjusted to the appropriate position, the third cylinder 48 works to drive the clamping tooth block 50 on one side of the clamping block 49 to be inserted into the corresponding tooth groove on the tooth seat 46 to limit and fix the tooth seat 46.

[0044] In the embodiment of the present invention, the implementation principle of a self-cleaning solar photovoltaic glass and its method is as follows: When cleaning the top surface of the photovoltaic glass main body 8, the second servo motor 19 on the first fixed block 18 operates to drive the second lead screw 20 to rotate. While the second lead screw 20 rotates, the wire sleeve block 21 will move accordingly, thereby driving the support bar 16 to move outward from the storage box 14. Water in the water supply pipe will be ejected from the water spray head 28 at the bottom of the water spray pipe 22 to wash the surface of the photovoltaic glass main body 8. At the same time, the cleaning sponge block 23 scrubs the surface of the photovoltaic glass main body 8 back and forth to enhance the cleaning effect of the photovoltaic glass main body 8. When it is necessary to replace the cleaning sponge block 23 at the bottom of the support bar 16, multiple stacked cleaning sponge blocks 23 are stored in the storage box 14. The support bar 16 will be retracted into the storage box 14 under the rotation of the second lead screw 20, adapting to the position of the support plate 31 stored in the storage box 14. At this time, the output end of the electric cylinder 34 on the clamping block 17 retracts, and the cleaning sponge block 23 will fall off. Then, the first cylinder 24 operates to drive the fixed bar 25 to move, and the push block 26 on the fixed bar 25 will slowly push out the cleaning sponge block 23 located on the support plate 31 and place it between the two clamping blocks 17 at the bottom of the support bar 16. Moreover, the electric cylinder 34 operates again to clamp the cleaning sponge block 23, completing the replacement of the cleaning sponge block 23. In snowy weather, the rolling gate motor 11 located on one side of the rolling gate storage frame 9 in the protection mechanism operates to drive the winding roller in the rolling gate storage frame 9 to rotate in the reverse direction, so that the rolling gate 12 slowly moves forward on the guide bar 10, and the rolling gate 12 will cover the upper position of the photovoltaic glass main body 8, preventing snow from accumulating on the surface of the photovoltaic glass main body 8 and not affecting the use efficiency of the photovoltaic glass main body 8. When adjusting the height position of the photovoltaic glass main body 8, the first servo motor 3 on the support column 2 in the lifting mechanism operates to drive the mounting seat 6 to move upward. At the same time, the tooth seat 46 moves upward in the guide seat 45. After the photovoltaic glass main body 8 is adjusted to the appropriate position, the third cylinder 48 on the L-shaped seat 47 operates to drive the clamping tooth block 50 on one side of the clamping block 49 to insert into the corresponding tooth groove on the tooth seat 46 to limit and fix the tooth seat 46;

[0045] When it is necessary to adjust the angle of the photovoltaic glass installation frame 7, the drive motor 36 at the fixed seat 35 operates to drive the driving gear 37 to rotate. While the driving gear 37 rotates, the connecting seat 39 will rotate accordingly. After the photovoltaic glass installation frame 7 is adjusted to the appropriate angle, the drive motor 36 stops operating, and the second cylinder 41 on the fixed seat 35 operates to drive the limit block 42 to move, so that the limit tooth block 43 on the limit block 42 inserts into the corresponding tooth groove on the limit gear 44 to limit and fix the limit gear 44.

[0046] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.

A method for self-cleaning solar photovoltaic glass, according to any one of claims 1 to 6, characterized in that: The following steps are involved: S1, the second servo motor (19) on the first fixed block (18) operates to drive the second screw rod (20) to rotate. When the second screw rod (20) rotates, the thread sleeve block (21) moves accordingly, thereby driving the support bar (16) to move outward from the storage box (14). Water in the tap water pipe is sprayed out from the water spray head (28) at the bottom of the water spray pipe (22) to rinse the surface of the photovoltaic glass body (8). At the same time, the cleaning sponge block (23) scrubs the surface of the photovoltaic glass body (8) back and forth to increase the cleaning effect of the photovoltaic glass body (8). When it is necessary to replace the cleaning sponge block (23) at the bottom of the support bar (16), a plurality of stacked cleaning sponge blocks (23) are stored in the storage box (14). The sponge block (23) and the support bar (16) are stored in the storage box (14) under the rotation of the second screw rod (20), and are adapted to the position of the support plate (31) stored in the storage box (14). At this time, the output end of the electric cylinder (34) on the clamping block (17) retracts, and the cleaning sponge block (23) falls off. Then the first cylinder (24) works to drive the fixed bar (25) to move, and the push block (26) on the fixed bar (25) slowly pushes out the cleaning sponge block (23) on the support plate (31) and places it between the two clamping blocks (17) at the bottom of the support bar (16).

When it is necessary to protect the photovoltaic glass body (8), the shutter motor (11) located on one side of the shutter plate storage frame (9) in the protection mechanism is operated, driving the winding roller in the shutter plate storage frame (9) to rotate in the opposite direction, thereby causing the shutter plate (12) to slowly move forward on the guide strip (10), and the shutter plate (12) will cover the upper part of the photovoltaic glass body (8), thereby protecting the photovoltaic glass body (8); S3. When adjusting the height position of the photovoltaic glass body (8), the first servo motor (3) on the support column 2 in the lifting mechanism operates to drive the mounting seat (6) to move upward. At the same time, the tooth seat (46) moves upward in the guide seat (45). After the photovoltaic glass body (8) is adjusted to a suitable position, the third cylinder (48) operates to drive the clamping tooth block (50) on one side of the clamping block (49) to be inserted into the corresponding tooth groove on the tooth seat (45), thereby limiting and fixing the tooth seat (46).
