DETAILED DESCRIPTION

[0025] It should be noted that the photovoltaic junction box body 1 is a mature and public technology in the prior art, so the specific internal structure and working principle thereof will not be described in detail in this article.

[0026] See also Figure 1-4 The fixing mechanism includes a pull plate 501 fixed to the top surface of the disassembly plate 3, two fixing blocks 502 are fixed on the left and right sides of the disassembly plate 3, two fixing grooves 503 are provided in the top wall of the photovoltaic junction box body 1 and on the left and right sides of the rectangular hole 2, and the fixing blocks 502 are slidably connected in the fixing grooves 503. The top surface of the photovoltaic junction box body 1 is provided with four disassembly grooves 504 respectively connected with the four fixing grooves 503. The disassembly grooves 504 are close to the front side of the fixing grooves 503, and the two are connected in an L shape. When maintenance is required, the pull plate 501 is pushed forward to drive the disassembly plate 3 to slide forward inside the rectangular hole 2, and then drive the fixing blocks 502 to slide forward inside the fixing grooves 503. When the fixing blocks 502 slide to the disassembly grooves 5 04, the pull plate 501 can be pulled upward, and the pull plate 501 drives the disassembly plate 3 to move upward, so that the fixed block 502 can be separated from the fixed groove 503 through the disassembly groove 504 for disassembly, and a receiving groove 505 is provided in the top wall of the photovoltaic junction box body 1 and in front of the rectangular hole 2, and an abutment plate 506 is slidably connected in the receiving groove 505, and two springs 507 are fixed on the front side of the abutment plate 506, and the front end of the spring 507 is fixed to the inner wall of the front side of the receiving groove 505. When the disassembly plate 3 moves forward, the abutment plate 506 will be pushed to slide forward inside the receiving groove 505 to compress the spring 507. When installing the disassembly plate 3, the above operation is reversed, and the elastic force of the spring 507 is released to cooperate with the abutment plate 506 to hold the disassembly plate 3 backward.

[0027] See also Figure 4 In the present embodiment, two guide grooves 508 are provided on the front of the abutment plate 506, and a guide block 509 is slidably connected in the guide groove 508. A guide rod 510 whose front end is fixed to the inner wall of the receiving groove 505 is fixed on the front of the guide block 509. The guide groove 508 is a T-shaped groove, and the guide block 509 and the guide rod 510 are connected in a T shape. Two springs 507 are respectively mounted on the outer peripheral walls of the two guide rods 510. When the abutment plate 506 slides back and forth, the guide groove 508 provided cooperates with the guide block 509 and the guide rod 510 to play a role of sliding guide, thereby improving the stability of the abutment plate 506 sliding back and forth, and at the same time avoiding the inconvenience caused by the abutment plate 506 sliding out of the receiving groove 505 excessively.

[0028] See also Figure 2 and Figure 5 In this embodiment, the limiting mechanism includes two limiting rods 601, and a mounting groove 602 for mounting the dustproof screen plate 4 is provided on the bottom surface of the disassembly plate 3. Flip grooves 603 are provided in the disassembly plate 3 and on the left and right sides of the mounting groove 602. The two limiting rods 601 are respectively hinged on the front inner walls of the two flip grooves 603. The bottom surface of the dustproof screen plate 4 is provided with two limiting grooves 604. An elastic rope 605 with one end fixed to the front inner wall of the flip groove 603 is fixed on the outer peripheral wall of the limiting rod 601. When the dustproof screen plate 4 needs to be disassembled, the limiting rod 601 is moved to make it flip inside the flip groove 603 and stretch the elastic rope 605, so that the end of the limiting rod 601 away from the hinge axis is separated from the limiting groove 604, and the dustproof screen plate 4 can be removed from the inside of the mounting groove 602 for cleaning. After cleaning, the above operation can be reversed to fix the dustproof screen plate 4.

[0029] The disassembly plate 3 is a rectangular ring plate, the mounting groove 602 is connected to the inner wall of the disassembly plate 3 in a T-shaped step, the mounting groove 602 is adapted to the dustproof mesh plate 4, the two flip grooves 603 are symmetrical on the left and right and are connected to the mounting groove 602, the flip groove 603 is opposite to the limit groove 604 on the left and right, and the limit groove 604 is connected to the side wall of the dustproof mesh plate 4.

[0030] The working principle of the above embodiment is:

[0031] (1) When maintenance is required, the pull plate 501 is pushed forward, so that it drives the disassembly plate 3 to slide forward inside the rectangular hole 2, and then drives the fixed block 502 to slide forward inside the fixed groove 503. When the fixed block 502 slides to the bottom of the disassembly groove 504, the pull plate 501 can be pulled upward, and the pull plate 501 drives the disassembly plate 3 to move upward, so that the fixed block 502 can be disassembled from the fixed groove 503 through the disassembly groove 504. When the disassembly plate 3 moves forward, it will push the abutment plate 506 to slide forward inside the accommodating groove 505 to compress the spring 507. When installing the disassembly plate 3, the above operation is reversed, and the spring 507 releases the elastic force to cooperate with the abutment plate 506 to push the disassembly plate 3 backward.

[0032] (2) When it is necessary to remove the dust screen 4, move the limit rod 601 to make it flip inside the flip groove 603 and stretch the elastic rope 605 so that the end of the limit rod 601 away from the hinge axis is disengaged from the limit groove 604. Then, the dust screen 4 can be removed from the installation groove 602 for cleaning. After cleaning, the above operation can be reversed to fix the dust screen 4.
