[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] This embodiment provides a closed switchgear, mainly used to solve the problem that when the fan is not turned on, external dust and foreign objects can enter the equipment box through the fan and fixed pipe, causing a large amount of dust to accumulate inside the equipment box, thus affecting the performance and lifespan of the equipment inside. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0025] A closed switchgear includes: an equipment compartment 1 with a ventilation slot 3 on its inner wall (the interior of the equipment compartment 1 is used for installing equipment); a fan 2 fixedly installed on the inner wall of the ventilation slot 3; and a rotating pipe 4 rotatably installed on the inner wall of the ventilation slot 3. The surface of the rotating pipe 4 has several slots 5 (two slots 5 are located on one side of the rotating pipe 4, and the other is located on the other side). In use, the user can turn on the fan 2 to allow the heat inside the equipment compartment 1 to pass sequentially through two slots 5, the rotating pipe 4, the other slot 5, the ventilation slot 3, and the fan. After the heat inside the equipment compartment 1 is exhausted, the user needs to control the rotating pipe 4 to rotate on the inner wall of the ventilation slot 3 through the drive unit 6, so that dust cannot enter the interior of the equipment compartment 1 through the rotating pipe 4. The main components of the drive unit 6 are: a fixed rod 61 fixedly installed at one end of the rotating pipe 4. In use, the user can rotate the rotating plate 62 fixedly installed at one end of the fixed rod 61, which drives the rotating pipe 4 to rotate. The first limiting unit 63 limits the rotating plate 62, thereby limiting the rotating pipe 4 on the inner wall of the ventilation slot 3.

[0026] like Figure 4 As shown, in some embodiments, the main components of the first limiting unit 63 are: two limiting holes 631, each opened on the surface of the rotating plate 62; a limiting rod 632 is slidably inserted into the inner wall of one of the limiting holes 631; under the action of the force application unit 633, the limiting rod 632 is held in place by a force within the inner wall of the limiting hole 631; the user can adjust the position of both ends of the rotating plate 62 by pulling the limiting rod 632 out of the limiting hole 631 and then rotating the rotating plate 62, so that the limiting rod 632 is inserted into the inner wall of the other limiting hole 631. The main components of the force application unit 633 are: a mounting plate 6331 fixedly installed on the surface of the equipment compartment 1, and a limiting rod 632 slidably inserted into the surface of the mounting plate 6331. A spring 6332 is slidably sleeved on the surface of the limiting rod 632. The two ends of the spring 6332 are fixedly installed on the surfaces of the mounting plate 6331 and the limiting rod 632, respectively. Therefore, in subsequent use, the user can pull the limiting rod 632 to stretch the spring 6332, so that the limiting rod 632 leaves the limiting hole 631 and releases the limitation on the rotating plate 62.

[0027] like Figure 2 As shown, in some embodiments, two perforated plates 7 are fixedly installed on the inner wall of the ventilation slot 3. When in use, the user can slide the two sponge columns 8 into the inner wall of the two slots 5 set on one side and then insert them into the inner wall of the ventilation slot 3, so that the two sponge columns 8 are both set on the surface of the two mesh plates, preventing dust from entering the interior of the equipment compartment 1 through the rotating pipe 4.

[0028] like Figures 1 to 5As shown, in some embodiments, two retrieval slots 9 are formed on the inner wall of the ventilation slot 3, and each of the two retrieval slots 9 is provided with a limiting ring 10. In use, the user can use the second limiting unit 11 to restrict the two limiting rings 10 to the inner walls of the two retrieval slots 9 respectively. Then, after the rotating tube 4 is rotated by the driving unit 6, the two slots 5 set on one side are aligned with the two retrieval slots 9. After removing the two limiting rings 10 by the second limiting unit 11, the two sponge columns 8 can be cleaned and replaced. The main components of the second limiting unit 11 are: several notches 11. 2. Limiting edges 111 are provided on the inner walls of the two retrieval slots 9. In use, the user slides the two limiting rings 10 into the inner walls of the two retrieval slots 9 respectively and they abut against the surfaces of the two limiting edges 111 respectively. Then, several notches 112 are slidably sleeved onto the surfaces of several sliders 113 that are fixedly installed on the surface of the equipment compartment 1. Finally, upper limit sleeves 115 are threaded onto the surfaces of several straight rods 114 that are fixedly installed on the surfaces of several sliders 113 respectively. This can achieve the limitation of the two limiting rings 10 on the inner walls of the two retrieval slots 9 by several notches 112.

[0029] The working process of this utility model is as follows: First, when the user needs to dissipate heat inside the equipment compartment 1, the fan 2 is turned on (there are multiple ways to control the fan 2; the fan 2 can be electrically connected to the electronic components of the equipment compartment 1 to control the fan 2). The heat inside the equipment compartment 1 is then discharged to the outside through two slots 5, rotating pipe 4, another slot 5, ventilation slot 3, and fan 2. When heat dissipation is not needed, the user can pull the limiting rod 632 out of the inner wall of one of the limiting holes 631, and then rotate the rotating plate 62 to insert the limiting rod 632 into the inner wall of the other limiting hole 631. This allows the rotating pipe 4 to rotate 180 degrees. At this time, dust cannot enter the interior of the rotating pipe 4 from the fan 2, and therefore cannot enter the interior of the equipment compartment 1, thus achieving the purpose of dust prevention.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
