[0002] The main function of photovoltaic glass is to serve as the outermost light-transmitting packaging panel of photovoltaic modules.

When the height position of the photovoltaic glass body 8 is adjusted, 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 body 8 is adjusted to a suitable position, the third cylinder 48 on the L-shaped seat 47 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, so as to limit and fix the tooth seat 46. When the angle of the photovoltaic glass mounting frame 7 needs to be adjusted, the driving motor 36 at the fixing seat 35 starts working, driving the active gear 37 to rotate.

7. 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). The electric cylinder (34) works again to clamp the cleaning sponge block (23), thereby completing the replacement of the cleaning sponge block (23). S2. 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).
