[0025] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings of the specification.

[0026] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an individual or selectively mutually exclusive embodiment with other embodiments.

[0028] Embodiment 1

[0029] Refer to Figures 1 to 3, which is the first embodiment of the present utility model. This embodiment provides a mechanism for facilitating the replacement of the dust-proof net of the box body, including a box body unit 100, which includes a box body 101. An installation plate 102 is arranged at the rear side inside the box body 101, and an opening and closing door 103 is connected to the front end of the box body 101;

[0030] A dust-proof unit 200, including dust-proof nets 201 arranged on both sides inside the box body 101, the front ends of which are flush with the front panel of the box body 101.

[0031] Furthermore, heat dissipation holes 101a are opened on both sides of the box body 101, and a plurality of them are evenly opened along the horizontal and vertical directions. A dust-blocking cover plate 101b is also arranged outside the heat dissipation holes 101a. The dust-blocking cover plate 101b is attached to the edge of the heat dissipation holes 101a, and its opening faces downward, which can prevent coal ash from naturally falling into the box body 101.

[0032] Furthermore, dust-proof net placement holes 101c are vertically opened on both sides of the front panel of the box body 101. The opening height ranges from the highest heat dissipation hole 101a to the lowest heat dissipation hole 101a. A dust-proof net sliding groove 101d is arranged at the lower end position of the dust-proof net placement hole 101c on the inner side of the box body 101, and it connects the front end to the rear end of the box body 101.

[0033] Furthermore, the dust-proof net 201 is matched with the dust-proof net sliding groove 101d and can completely cover the range of the heat dissipation holes 101a. Its front end is a sealing plate 201a, which is matched with the dust-proof net placement hole 101c and is five to ten millimeters lower than the dust-proof net placement hole 101c. The dust-proof net 201 is vertically and horizontally spaced with mesh holes 201b, which can block and collect coal ash. A clamping groove 201c is opened at the upper end of the connection position between it and the sealing plate 201a.

[0034] During use, after connecting the wires and closing the box body 101, the dust-proof net 201 is slid into the box body 101 from the dust-proof net placement hole 101c along the dust-proof net sliding groove 101d until the sealing plate 201a coincides with the dust-proof net placement hole 101c. At this time, the dust-proof net 201 completely covers the range of the heat dissipation holes 101a, and can block and collect the coal ash entering the inside of the box body 101.

[0035] In summary, by setting the dust-proof net 201, while meeting the heat dissipation requirements, it can effectively prevent dust in the environment and ensure the safe operation of the equipment.

[0036] Embodiment 2

[0037] Refer to Figures 1 to 3, which is the second embodiment of the present utility model. Based on the previous embodiment, this embodiment further provides a mechanism for facilitating the replacement of the dust-proof net of the box body, including a quick-installation unit 300, which includes a release component 301 arranged inside the box body 101 and cooperating with the dust-proof net 201, and a baffle component 302 arranged at the front end inside the box body 101.

[0038] Furthermore, the release component 301 includes a release push plate 301a and a push plate spring 301b connected thereto. The rear end of the push plate spring 301b is fixedly arranged on the rear panel of the box body 101, and the front end is fixedly connected to the upper end of the release push plate 301a. The push plate spring 301b always provides an elastic force to the release push plate 301a, which is used for clamping the dust-proof net 201 and closing the dust-proof net placement hole 101c after the dust-proof net 201 is taken out.

[0039] Furthermore, two telescopic rods 301a-1 are symmetrically arranged up and down on the front side of the release push plate 301a. The front end of the telescopic rod 301a-1 is provided with a connecting plate 301a-2. An end plate 101e is also arranged on the inner side of the box body 101, and a telescopic hole 101e-1 is opened thereon. The telescopic rod 301a-1 cooperates with the telescopic hole 101e-1. The end plate 101e can limit the forward pushing distance of the release push plate 301a. At the same time, the connecting plate 301a-2 can limit the backward pushing distance of the release push plate 301a. When the sealing plate 201a coincides with the dust-proof net placement hole 101c, the connecting plate 301a-2 just touches the end plate 101e to limit it.

[0040] Furthermore, the baffle component 302 includes a baffle 302a cooperating with the dust-proof net 201, which is vertically slidably arranged at the front end inside the box body 101. Its width and height are the same as those of the dust-proof net placement hole 101c. When the baffle 302a is in the closed state, it can completely cover the dust-proof net placement hole 101c. The upper end of the baffle 302a is also connected with a baffle spring 302b. The upper end of the baffle spring 302b is fixedly connected to the box body 101, and it always provides a downward elastic force to the baffle 302a.

[0041] Furthermore, an opening and closing plate 302a-1 extends out at a position three to five millimeters away from the lower side of the front end of the baffle 302a, and it extends out of the dust-proof net placement hole 101c. The lower end of the baffle 302a cooperates with the clamping groove 201c to limit the placement of the dust-proof net 201.

[0042] Furthermore, the baffle component 302 also includes a clamping block 302c cooperating with the baffle 302a. The clamping block 302c is rotatably arranged inside the box body 101. A clamping block torsion spring 302d is arranged between it and the box body 101. The clamping block 302c can limit the lower end of the baffle 302a, and the clamping block torsion spring 302d provides a torsional force for it to stick to the baffle 302a.

[0043] Further, the lower end of the clamping block 302c is a triangular inclined plane block 302c-1, which cooperates with the lower end of the baffle 302a. In the state where the clamping block 302c clamps the baffle 302a, by placing the dust-proof net 201, the triangular inclined plane block 302c-1 can be pushed to disengage the limit on the clamping block 302c.

[0044] During use, when it is necessary to place the dust-proof net 201, the opening and closing plate 302a-1 is pulled up to open the dust-proof net placement hole 101c. When it is pulled up to its top, the clamping block 302c will limit the lower end of the baffle 302a. At this time, the dust-proof net 201 can be placed. During the placement process, the rear end of the dust-proof net 201 will squeeze and release the push plate 301a. When the connecting plate 301a-2 touches the limiting plate 101e, the sealing plate 201a completely coincides with the dust-proof net placement hole 101c. At this time, the lower end of the baffle 302a just engages with the engaging groove 201c to limit it, and the installation is completed; when the dust-proof net 201 needs to be replaced, the opening and closing plate 302a-1 is pulled up to release the limit on the dust-proof net 201. Under the action of the push plate spring 301b, it is pushed to pop out a section to facilitate its removal. After it is completely removed, the baffle 302a will close and protect the dust-proof net placement hole 101c under the action of the baffle spring 302b.

[0045] In summary, the release component 301 can make the dust-proof net 201 easy to pop out. Cooperating with the baffle component 302, the dust-proof net 201 can be conveniently replaced without shutting down the machine, which can meet the requirement of frequent replacement of the dust-proof net in the junction box in some dusty environments.
