Linkage component 51 includes a motor 511, and the motor 511 is installed inside the inner slot 2. The output end of the motor 511 is connected to a transmission screw 512, and a screw sleeve 513 is screwed around one side of the transmission screw 512. An assembly guide 514 is fixed inside the screw sleeve 513, and a guide sleeve 515 is connected below the assembly guide 514. A guide sleeve 515 is provided below the transmission screw 512 in the cleaning area 3 for guiding the guide sleeve 515. A brush holder 52 is installed at the front end of the guide rod 516 and the assembly guide 514, and a processing component 53 is installed at the rear end of the assembly guide 514. The processing component 53 includes a connecting frame 531, which is fixed to the rear end of the assembly guide 514. The other end of the connecting frame 531 is connected to a fixing frame 532, and a fan component 533 is installed in the middle of the fixing frame 532. When there is dust and impurities left on the filter frame 4 of the photovoltaic module junction box body 1 due to daily heat dissipation, personnel can periodically start the motor 511 to rotate the transmission screw 512. When the screw is activated, the lead screw sleeve 513, which interacts with the lead screw, can carry the assembly guide frame 514 and the brush frame 52 installed at its front end to move laterally along the inner edge of the filter screen frame 4 along the guide sleeve 515 and the guide rod 516. Thus, the brush frame 52 can brush away the dust accumulated on the surface of the filter screen frame 4 from the inside to the outside. During this process, the personnel can simultaneously start the fan component 533. The airflow of the fan component 533 also moves synchronously from the inside to the outside along with the brush frame 52, thereby reducing the amount of dust that falls into the box after being brushed off and improving the cleanliness of the box.

[0027] The portable assembly / disassembly mechanism 6 includes a hinge 61, which is mounted on the upper side of the junction box body 1. A cover plate 62 is connected to one side of the hinge 61.

It is portable and practical.

[0028] Working Principle: When dust and impurities accumulate on the filter frame 4 of the photovoltaic module junction box body 1 due to daily heat dissipation, personnel can periodically start the motor 511 to rotate the transmission screw 512. At this time, the screw sleeve 513, which interacts with the screw, can carry the assembly guide 514 and the brush frame 52 installed at its front end to move laterally along the inner edge of the filter frame 4, guided by the guide sleeve 515 and the guide rod 516. Thus, the brush frame 52 can brush away the dust accumulated on the surface of the filter frame 4 from the inside out. During this process, personnel can simultaneously start the fan 533. The airflow of the fan 533 also moves synchronously from the inside out with the brush frame 52, thereby reducing the amount of dust that falls into the box after being brushed off, improving the cleanliness of the box. Secondly, when the brush frame 52 wears out after long-term use... When wear and tear affect the subsequent cleaning effect, the brush holder 52 can be moved to the inside of the front cleaning area 3 of the junction box body 1 by using the transmission of the linkage component 51. The brush holder 52 can then be exposed by using the pre-set hinge 61 at the top of the junction box body 1 to flip the cover plate 62. The brush holder 52 can then be squeezed by the upper outer part of the two guides 634 on the top of the mounting block 632 above the brush holder 52 with two fingers. Under the pull of the return spring 635, the inner limit rods 636 of the two guides 634 can be disengaged from the two pre-set limit grooves 637 of the assembly guide 514. The brush holder 52 can then be removed by the guide of the limit guide groove 631. The brush holder 52 can then be replaced with a new one. It is portable and practical.
