[0020] Please see Figures 1-4The present invention provides the following technical solution: a power distribution box for power engineering management, including a power distribution box body 1 and a cooling fan 11. An outer edge connecting frame 2 is fixedly connected to one side of the power distribution box body 1. An insertion hole 21 is opened at the top of the outer edge connecting frame 2. An extension connecting frame 3 is inserted into the outer edge connecting frame 2. A permanent filter cotton 31 is fixedly connected to one side of the extension connecting frame 3. A permanent interception net 32 ​​is fixedly connected to the outer wall of the permanent filter cotton 31. A temporary filter frame 4 is detachably connected to the outer edge connecting frame 2. A temporary interception frame 41 is fixedly connected to one side of the temporary filter frame 4.

[0021] In this implementation plan: During normal use, the extension connecting frame 3 is engaged in the outer edge connecting frame 2. At this time, the extension connecting frame 3 blocks and seals the insertion hole 21. External air passes through the double-layer filtration of the constant solid interception net 32 ​​and the constant solid filter cotton 31 into the outer edge connecting frame 2, and is then drawn into the distribution box body 1 by the cooling fan 11 and discharged from the exhaust port on the other side. When it is necessary to disassemble and clean the constant solid filter cotton 31 and the constant solid interception net 32, the staff inserts the temporary filter frame 4 and the temporary interception frame 41 downwards through the insertion hole 21 for temporary filtration. The bottom ends of frame 4 and temporary intercept frame 41 abut against the outer sealing ring 33, sealing the insertion hole 21. Then, the extension connecting frame 3 is pulled outwards, and the temporary filter frame 4 and temporary intercept frame 41 are fully inserted downwards. At this point, the insertion hole 21 is sealed, and the side opening of the outer edge connecting frame 2 is sealed by the extension connecting frame 3 and the outer sealing ring 33. During the installation of the temporary filter frame 4 and temporary intercept frame 41, external dust will not enter the outer edge connecting frame 2. Then, the extension connecting frame 3 is completely removed from the outer edge connecting frame 2. At this point, the temporary filter... Frame 4 and temporary interception frame 41 replace the permanent filter cotton 31 and permanent interception net 32 ​​to filter the air entering the distribution box body 1. With the lateral extension of the outer edge connecting frame 2, the detachable connection of the outer edge connecting frame 2 and the extension connecting frame 3, and the integrated structure of the extension connecting frame 3, the permanent filter cotton 31 and the permanent interception net 32, the staff can quickly disassemble and wash the permanent filter cotton 31 and the permanent interception net 32 ​​without opening the cabinet door. The temporary filter frame 4 and temporary interception frame 41 are inserted through the plug hole 21. The installation method, combined with the sealing of the insertion hole 21 by the extension connecting frame 3, can prevent dust falling from the constant solid filter cotton 31 and constant solid interception net 32 ​​from entering the distribution box body 1 when the constant solid filter cotton 31 and constant solid interception net 32 ​​are disassembled and cleaned. This maintains effective filtration of the gas entering the distribution box body 1 and solves the problem that dust in the outside air and dust shaken off from the constant solid filter cotton 31 and constant solid interception net 32 ​​can enter the distribution box body 1 through the ventilation port 12 or the cabinet door of the distribution box body 1 during the disassembly and cleaning of the filter structure.

[0022] The side wall of the distribution box body 1 is provided with a ventilation opening 12, which corresponds to the position of the outer edge connecting frame 2; the ventilation opening 12 can make way for space.

[0023] A current-gathering cavity plate 13 is fixedly connected to the inner wall of the distribution box body 1, and a cooling fan 11 is fixedly connected to one side of the current-gathering cavity plate 13. The openings on both sides of the current-gathering cavity plate 13 are respectively matched with the size of the cooling fan 11 and the ventilation port 12. The current-gathering cavity plate 13 can play a guiding role. The outer edge connecting frame 2 and the ventilation port 12 have a larger area, which provides a larger ventilation volume through the larger area.

[0024] The bottom inner wall of the outer edge connecting frame 2 is provided with a bottom positioning groove 22, which corresponds to the position of the insertion hole 21. By setting the bottom positioning groove 22, the bottom of the temporary filter frame 4 and the temporary interception frame 41 can be positioned, so that the temporary filter frame 4 and the temporary interception frame 41 can be stably installed in the outer edge connecting frame 2.

[0025] The inner walls of the insertion hole 21 and the bottom positioning groove 22 are both fixedly connected with inner sealing gaskets 23, and the inner walls of the outer edge connecting frame 2 are fixedly connected with side sealing gaskets 24. The side sealing gaskets 24 correspond to the positions of the temporary filter frame 4 and the temporary interception frame 41. By setting the inner sealing gaskets 23 and the side sealing gaskets 24 together, a sealing effect can be achieved when the temporary filter frame 4 and the temporary interception frame 41 are inserted into the outer edge connecting frame 2, so as to prevent dust from entering the distribution box body 1 through the gaps.

[0026] An outer sealing ring 33 is fixedly connected to the outer wall of the extension connecting frame 3, and a magnetic positioning ring 34 is fixedly connected to one side of the extension connecting frame 3. By setting the outer sealing ring 33, the gap between the outer edge connecting frame 2 and the extension connecting frame 3 can be sealed. The magnetic positioning ring 34 can be magnetically connected to the outer edge connecting frame 2 to prevent the extension connecting frame 3 from falling off the outer edge connecting frame 2.

[0027] The top of both the temporary filter frame 4 and the temporary interception frame 41 is fixedly connected to a top positioning plate 42; the top positioning plate 42 can play a positioning role. After the temporary filter frame 4 and the temporary interception frame 41 are inserted into the outer edge connecting frame 2, the top positioning plate 42 is attached to the top of the outer edge connecting frame 2.

[0028] The working principle and usage process of this utility model: The extension connecting frame 3 is engaged in the outer edge connecting frame 2. At this time, the extension connecting frame 3 blocks and seals the insertion hole 21. External air passes through the double-layer filtration of the constant solid interception net 32 ​​and the constant solid filter cotton 31 and enters the outer edge connecting frame 2. It is then drawn into the distribution box body 1 by the cooling fan 11 and discharged from the exhaust port on the other side. When it is necessary to disassemble and clean the constant solid filter cotton 31 and the constant solid interception net 32, the staff inserts the temporary filter frame 4 and the temporary interception frame 41 downwards through the insertion hole 21. The bottom ends of the temporary filter frame 4 and the temporary interception frame 41 abut against the outer sealing ring 33. The insertion hole 21 is sealed, and then the extension connecting frame 3 is pulled outwards. The temporary filter frame 4 and the temporary intercepting frame 41 are then fully inserted downwards. At this time, the insertion hole 21 is sealed, and the side opening of the outer edge connecting frame 2 is sealed by the extension connecting frame 3 and the outer sealing ring 33. During the installation of the temporary filter frame 4 and the temporary intercepting frame 41, external dust will not enter the outer edge connecting frame 2. Then the extension connecting frame 3 is completely removed from the outer edge connecting frame 2. At this time, the temporary filter frame 4 and the temporary intercepting frame 41 replace the permanent filter cotton 31 and the permanent intercepting net 32 ​​to filter the air entering the distribution box body 1.
