[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figures 1-5The low-voltage distribution cabinet shown includes a cabinet body 1 and a cooling fan 2. The cooling fan 2 is fixedly installed on the side of the cabinet body 1. A filter structure 3 is installed on the side of the cabinet body 1 and below the cooling fan 2. The filter structure 3 includes a first filter plate 301 and a second filter plate 302. The first filter plate 301 is fixedly installed on the side of the cabinet body 1, and its outer wall has a plurality of first filter holes 303 evenly spaced. The second filter plate 302 is fixedly installed inside the cabinet body 1 and located on one side of the first filter plate 301. Its outer wall has a plurality of second filter holes 304 with a diameter larger than the first filter holes 303. The positioning of the first filter plate 301 and the second filter plate 302 allows the internal temperature of the cabinet body 1 to be cooled by the cooling fan 2. As the cold air descends, it can circulate through the second filter holes 304 on the second filter plate 302. The air inside the cabinet body 1 passes through the first filter plate 301 and the second filter plate 302. 02. While airflow occurs, the difference in diameter between the first filter hole 303 and the second filter hole 304 ensures that the space for air to flow outward in the main body of the distribution cabinet 1 is greater than the space for air to flow inward from the outside. This ensures that while air flows outward from the main body of the distribution cabinet 1, the dust particles carried by the outside air flowing inward are blocked by the first filter hole 303. Particles larger than the first filter hole 303 are directly blocked outside the first filter plate 301. Some dust particles that pass through the first filter hole 303 can also fall between the first filter plate 301 and the second filter plate 302 due to the distance between them. This greatly improves the cleanliness of airflow and prevents excessive external dust from entering the main body of the distribution cabinet 1 and damaging the electrical structure. This improves the quality of the internal environment of the main body of the distribution cabinet 1 and also enhances the filtration effect of external dust particles.

[0028] Furthermore, the filter structure 3 also includes a connecting plate 305, which is fixedly disposed between the first filter plate 301 and the second filter plate 302. The top end of the connecting plate 305 is arc-shaped. The connecting plate 305 is used to limit the installation position between the first filter plate 301 and the second filter plate 302. The connecting plate 305 is fixedly disposed between the first filter plate 301 and the second filter plate 302 through the fixing structure 4, so that the dust between the first filter plate 301 and the second filter plate 302 can fall to the top end of the connecting plate 305. The connecting plate 305 can fix the position of the first filter plate 301 and the second filter plate 302, while also serving as a container for dust particles. The arc shape at the top end of the connecting plate 305 allows dust particles to accumulate at the top end of the connecting plate 305, thus providing convenience for subsequent unified cleaning and enhancing the integrity and practicality of the filtration of the first filter plate 301 and the second filter plate 302.

[0029] Furthermore, a fixing structure 4 is provided between the connecting plate 305 and the first filter plate 301. The fixing structure 4 includes a fixing groove 402 and a fixing rod 401. The fixing rod 401 has an I-shaped cross-section and is movably inserted into the outer wall of the first filter plate 301. The fixing groove 402 is formed on the outer wall of the connecting plate 305. The diameter of the bottom end of the inner cavity of the fixing groove 402 is larger than the diameter of the middle and top ends of the inner cavity. One end of the fixing rod 401 passes through the first filter plate 301 and is inserted into the inner cavity of the fixing groove 402. A positioning component is provided on the outer wall of the fixing rod 401, and the cross-section of the fixing groove 402 is matched. Figure 4 neutralization Figure 5 As shown in the diagram, the diameter of the deep cavity of the fixing groove 402 is larger than the diameter of the middle and inlet of the cavity, and the cross-sectional shape of the fixing groove 402 is a U-shape to match the end of the fixing rod 401, as shown. Figure 5 The filter plate 301, consisting of a circle and two rectangular sections, is connected to the inner cavity of the fixing groove 402 by a fixing rod 401 that passes through the first filter plate 301. After the fixing rod 401 is inserted deep into the inner cavity of the fixing groove 402, rotating the fixing rod 401 ensures a stable connection between the fixing rod 401 and the fixing groove 402 due to their shape difference, preventing the fixing rod 401 from being pulled out directly from the inner cavity of the fixing groove 402. Thus, while fixing the fixing rod 401 and the fixing groove 402, it also fixes the first filter plate 301 and the connecting plate 305. Similarly, the second filter plate 302 and the connecting plate 305 can also be fixed. This provides support for the installation of the first filter plate 301 and the second filter plate 302, creating space for dust particles to fall and be collected between the first filter plate 301 and the second filter plate 302, and enhancing the effectiveness of the installation of the first filter plate 301 and the second filter plate 302.

[0030] Finally, the positioning assembly includes a positioning groove 404 and a positioning block 403. The positioning groove 404 is located inside the main body 1 of the distribution cabinet and is connected to the interior of the first filter plate 301. The positioning block 403 is movably mounted on the outer wall of the fixing rod 401. The end of the positioning block 403 away from the fixing rod 401 is inserted into the inner cavity of the positioning groove 404. A spring 405 is fixedly mounted on the end of the positioning block 403 away from the positioning groove 404. The end of the spring 405 away from the positioning block 403 is fixedly mounted on the inner wall of the fixing rod 401. The positioning block 403 moves laterally as the fixing rod 401 is inserted into the fixing groove 402. When the fixing rod 401 is fixedly connected to the inner cavity of the fixing groove 402 by rotation, the positioning block 403 will rotate circumferentially with the rotation of the fixing rod 401 until it moves above the inner cavity of the positioning groove 404. Supported by the fixed rod, it will pop out downwards and intersect with the inner cavity of the positioning groove 404, thereby fixing the fixed rod 401 at the position where it intersects with the positioning groove 402. At the same time, it can fix the positions of the first filter plate 301 and the connecting plate 305. Conversely, when it is necessary to clean the dust particles on the connecting plate 305, the fixed rod 401 can be rotated in the opposite direction, causing the positioning block 403 to rotate. The positioning block 403 will then separate from the inner cavity of the positioning groove 404 by the compression property of the spring 405, thereby releasing the fixation between the fixed rod 401 and the positioning groove 402. This allows the fixed rod 401 to separate from the positioning groove 402, thus enabling the first filter plate 301 and the connecting plate 305 to be removed from the main body of the distribution cabinet 1 for cleaning. This effectively improves the flexibility of the first filter plate 301 and the connecting plate 305 in disassembly and assembly, and also enhances the practicality of the filter structure 3.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
