[0029] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0030] like Figures 1 to 5 As shown, a dustproof shed for unit maintenance with a smoke and dust purification function includes a cubic main frame 1, the main frame 1 includes a plurality of unit frames 11, and the plurality of unit frames 11 are spliced ​​with each other. A dust removal unit 2 is provided on one side of the main frame 1, and a main through-pipe 6 is connected to the interface of the dust removal unit 2. One end of the main through-pipe 6 extends to the interior of the main frame 1 and is connected to a first branch pipe 7 and a plurality of second branch pipes 8.

[0031] The end of the first branch pipe 7 is connected to the movable suction pipe 3, and the end of each second branch pipe 8 is connected to the flexible extension pipe 4. One end of the movable suction pipe 3 is limited to the top of the main frame 1, and the other end is free to move inside the main frame 1, which is used to realize movable dust collection inside the main frame 1; the flexible extension pipes 4 are evenly arranged inside the main frame 1, which is used to realize fixed-point dust collection inside the main frame 1.

[0032] Several monitoring modules are also provided within the main frame 1, and a monitoring display is provided on the outside of the main frame 1. The monitoring display is electrically connected to the several monitoring modules and the dust removal unit 2 to control the opening and closing of the dust removal unit 2. The dustproof shed for maintenance in this application uses a movable suction pipe 3 and several flexible extension pipes 4 to achieve fixed-point and precise dust collection within the main frame 1. In conjunction with the monitoring modules, smoke and dust can be detected immediately and the operation of the dust removal unit 2 can be controlled to achieve smoke and dust purification operation. The monitoring module uses a dust sensor, which is a common technical means in the prior art.

[0033] A cross connector 12 is provided between multiple unit frames 11 in the same plane, and a side connector 13 is provided between two unit frames 11 perpendicular to each other. Specifically, the unit frames 11 at the upper and lower ends are fixedly connected to the side unit frames 11 through the side connectors 13. The side connectors 13 can specifically be L-shaped angle irons, and the adjacent unit frames 11 on the side are connected by locking members, so that the main frame 1 can be quickly disassembled and assembled, which is convenient for temporarily building the dustproof shed of this application at the maintenance point.

[0034] A crossbeam 5 is detachably mounted in the main frame 1. A plurality of connecting hangers 53 are fixed to the crossbeam 5 at intervals. The crossbeam 5 and the top unit frame 11 are mounted via the connecting hangers 53. A receiving groove 51 is provided in the crossbeam 5, and the receiving groove 51 passes through the bottom wall of the crossbeam 5. The first branch pipe 7 is placed in the receiving groove 51. The first branch pipe 7 is a foldable telescopic tube, specifically a bellows that can be extended or retracted. The groove diameter of the receiving groove 51 near the bottom wall of the crossbeam 5 is smaller than the diameter of the first branch pipe 7, while the groove diameter in the middle area of ​​the receiving groove 51 is larger than the diameter of the first branch pipe 7, thereby enabling the first branch pipe 7 to slide and retract within the receiving groove 51.

[0035] Furthermore, an interface structure 9 is slidably mounted on the crossbeam 5. This interface structure 9 comprises a sliding frame 91 and a joint pipe 92. One end of the joint pipe 92 extends into the receiving groove 51 and communicates with the first branch pipe 7, while the other end extends out of the crossbeam 5 and communicates with the movable suction pipe 3. An enlarged portion 93 is provided around the sliding frame 91. The enlarged portion 93 is located within the receiving groove 51 and is in sliding contact with the bottom wall of the receiving groove 51.

[0036] At the same time, multiple slide bars 52 are formed on both sides of the crossbeam 5. The sliding frame 91 includes a frame body 911 located on both sides of the crossbeam 5 and multiple rollers 912 rotatably mounted on the frame body 911. Some rollers 912 are clamped between two adjacent slide bars 52, while some rollers 912 are located above the slide bars 52. The frame body 911 clamps the crossbeam 5, allowing the sliding frame 91 to slide stably along the crossbeam 5. The design of the rollers 912 makes the sliding frame 91 slide smoothly relative to the crossbeam 5.

[0037] The movable suction pipe 3 includes a flexible suction arm 31 and an suction hood 32 connected to the tail end of the flexible suction arm 31. When it is necessary to move the movable suction pipe 3 to realize fixed-point dust collection by the suction hood 32, the movable suction pipe 3 can be pulled, and the movable suction pipe 3 drives the frame 911 to move along the beam 5. Several rollers 912 on the frame 911 are limitedly set on the upper and lower sides of the slide bar 52 and slide until it moves to the work station position to perform dust collection operations.

[0038] By setting up an interface structure 9 and a retractable first branch pipe 7, and at the same time the length of the movable suction pipe 3 is not less than the height of the main frame 1, when the movable suction pipe 3 is used for dust removal, the staff can hold the movable suction pipe 3 and move it to various areas within the main frame 1 to achieve precise dust removal.

[0039] At the same time, multiple second branch pipes 8 are evenly distributed in the main frame 1. In the embodiment of the present application, four flexible extension pipes 4 are distributed around the inside of the main frame 1. In actual use, they can be set according to the size of the main frame 1 to ensure the smoke and dust purification effect inside the main frame 1. The lower end of each flexible extension pipe 4 is fixedly connected to the air suction port, and the fixed-point dust collection in the main frame 1 is achieved by setting the flexible extension pipe 4.

[0040] The flexible extension tube 4 of the present application is arranged at the four corners of the main frame 1, which reduces the impact on the use of the internal space and realizes the fixed-point dust collection effect within the main frame 1; in addition, in conjunction with the flexible extension tube 4, the flexible extension tube 4 can be flexibly moved to increase the dust collection efficiency in the maintenance area, and then the dust in the area with higher dust density can be quickly removed; through the coordinated use of the flexible extension tube 4 and the movable suction tube 3, the dust collection effect and efficiency are improved.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
