[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides Figures 1 to 8 The corner guard assembly shown includes multiple sets of protective corner guards 1, which are clamped at the four corners of the photovoltaic panel 18. A winding drum 2 is installed on the top of the photovoltaic panel 18. The inner cavity of the winding drum 2 is rotatably connected to the winding shaft 3 through a bearing. Multiple sets of traction ropes 4 are wound around the outside of the winding shaft 3. The other end of the traction rope 4 passes through the winding drum 2 and extends outward and is connected to the protective corner guard 1. A ratchet 5 is fixedly connected to the outside of the winding shaft 3. A fixing ring 6 is fixed to the top of the inner cavity of the winding drum 2. The inner cavity of the fixing ring 6 is rotatably connected to a pawl 7 that engages with the ratchet 5. A support spring 8 is fixed to the inner cavity of the fixing ring 6. The other end of the support spring 8 is fixed to the outer side of the pawl 7.

[0030] The traction rope 4 is tightened by rotating the reel 3, and the traction protection corner guard 1 is put on the four corners of the photovoltaic panel 18. Then, during the transportation and installation process, the corners of the photovoltaic panel 18 are protected. At the same time, when installing the photovoltaic panel 18, the installation angle code 20 is clamped between the two sets of glass plywood 181, and then the installation angle code 20 is connected to the installation frame 19 through the locking assembly, so as to effectively protect and quickly install the photovoltaic panel 18 when it has no frame.

[0031] A suction cup 9 is fixed to the bottom of the winding drum 2, and the suction cup 9 is adsorbed on the top of the photovoltaic panel 18. The top of the winding shaft 3 passes through the outside of the winding drum 2 and is fixed with a handle 10. Through the setting of the suction cup 9, it is convenient to limit and fix the winding drum 2, and then support the winding drum 2, ensuring that the traction ropes 4 around it have sufficient traction to pull the protective corner guard 1, and at the same time prevent the winding drum 2 from contacting the photovoltaic panel 18, causing damage to the photovoltaic panel 18.

[0032] A threaded hole 11 is provided at the top of the protective corner guard 1, and the inner cavity of the threaded hole 11 is threadedly connected to a threaded connecting column 12. The end of the traction rope 4 away from the winding shaft 3 is sleeved on the outside of the threaded connecting column 12. The threaded connecting column 12 can be installed through the threaded hole 11 and then connected to the traction rope 4, which is convenient for disassembly and assembly of the traction rope 4, leaving the protective corner guard 1 independently sleeved at the corner of the photovoltaic panel 18.

[0033] A movable ring 13 is provided on the outer side of the winding shaft 3, and multiple groups of sliding grooves 14 are provided at the bottom of the movable ring 13. The inner cavity of the sliding groove 14 is slidably connected to a connecting rod 15. A guide groove 16 is provided on the top of the winding drum 2. The end of the connecting rod 15 away from the movable ring 13 passes through the guide groove 16 and is fixedly connected to the pawl 7. Through the setting of the movable ring 13, the connecting rod 15 can be moved, which facilitates the movement of the pawl 7 and the separation of the ratchet 5, and facilitates the tightness adjustment of the traction rope 4.

[0034] A protective pad 17 is bonded to the inner side of the protective corner guard 1, and the protective pad 17 is attached to the outer side of the photovoltaic panel 18. The setting of the protective pad 17 facilitates the protection of the photovoltaic panel 18 and prevents the traction rope 4 from pulling the protective corner guard 1 and getting stuck on the photovoltaic panel 18. The protective corner guard 1 is stuck at the corner of the photovoltaic panel 18, which may easily cause the photovoltaic panel 18 to break. The protective pad 17 plays the role of isolation and protection.

[0035] Based on a corner protection assembly, a frameless double-glass photovoltaic device is also provided, including a photovoltaic panel 18, the photovoltaic panel 18 includes two groups of glass clamps 181, a battery cell 182 is sandwiched between the glass clamps 181, a mounting frame 19 is provided at the bottom of the photovoltaic panel 18, mounting angle codes 20 are clamped on both sides of the photovoltaic panel 18, and a locking assembly for fastening the mounting angle codes 20 is provided in the inner cavity of the mounting frame 19; the photovoltaic panel 18 includes two groups of glass clamps 181, a battery cell 182 is sandwiched between the glass clamps 181, a mounting frame 19 is provided at the bottom of the photovoltaic panel 18, mounting angle codes 20 are clamped on both sides of the photovoltaic panel 18, and a locking assembly for fastening the mounting angle codes 20 is provided in the inner cavity of the mounting frame 19;

[0037] The locking assembly includes a connecting block 21 that is slidably set in the inner cavity of the mounting frame 19, two groups of through holes are opened at the bottom of the mounting angle code 20, and the inner cavity of the through hole is provided with mounting screws 22, and two groups of mounting holes 23 that are threadedly connected to the mounting screws 22 are opened at the top of the connecting block 21. The mounting angle code 20 and the connecting block 21 are connected and tightened by the mounting screws 22, and then the photovoltaic panel 18 is fixed using the mounting angle code 20.

[0038] A first tooth groove 24 is provided at the front and rear ends of the top of the connecting block 21, and a second tooth groove 25 is provided at the top of the inner cavity of the mounting frame 19 to engage with the first tooth groove 24. The mutual engagement of the first tooth groove 24 and the second tooth groove 25 facilitates the limiting of the connecting block 21 to prevent the connecting block 21 from sliding in the mounting frame 19 and making it impossible to limit the position of the photovoltaic panel 18.

[0039] A gasket 26 is clamped on the top of the mounting frame 19, and the top of the gasket 26 is attached to the bottom of the photovoltaic panel 18. The setting of the gasket 26 facilitates the protection of the photovoltaic panel 18 to prevent the photovoltaic panel 18 from directly contacting the mounting frame 19 and causing damage to the glass splint 181.

[0040] The two sets of glass panels 181 are connected by means of sealant. The thickness of the mounting angle code 20 is smaller than the distance between the two sets of glass panels 181. By filling the glass panels 181 with sealant, not only the battery cells 182 can be encapsulated, but also the two sets of glass panels 181 can be bonded.

[0041] During specific use, the protective corner guard 1 is put on the corner of the photovoltaic panel 18, and then the suction cup 9 is used to adsorb the winding drum 2 on the photovoltaic panel 18, and then the winding shaft 3 is rotated, and the traction rope 4 is used to pull the protective corner guard 1. At the same time, the winding shaft 3 remains stable with the cooperation of the ratchet 5 and the pawl 7, so that the photovoltaic panel 18 can be conveniently carried through the handle 10. When the frameless double-glass photovoltaic panel 18 needs to be installed, the installation angle code 20 is first clamped on both sides of the photovoltaic panel 18, and then the photovoltaic panel 18 is placed on the installation frame 19, and the installation screws 22 are used to connect it to the connecting block 21 in the installation frame 19. The connecting block 21 is moved upward in the installation frame 19 by installing the screws 22, so that the first tooth groove 24 is engaged with the second tooth groove 25, and the connection block 21 is restricted from sliding in the installation frame 19. At the same time, there is a gasket 26 between the photovoltaic panel 18 and the installation frame 19 to protect the photovoltaic panel 18.
