DETAILED DESCRIPTION

[0018] Reference Figures 1 to 4 As shown, the utility model provides a dust-proof low-voltage control cabinet, comprising: a cabinet body 1 and a dust removal box 4, the upper surface of the cabinet body 1 is fixedly connected to an exhaust plate 11, a sealing plate 12 is slidably connected to the exhaust plate 11 through a spring, and the lower end of the cabinet body 1 is fixedly connected to a partition plate 2, and the partition plate 2 is fixedly connected to a filter plate 3, and at the same time, an air inlet 6 is opened at the lower end of the side of the cabinet body 1, the air inlet 6 is fixedly connected to an air pump 5, and the bottom of the cabinet body 1 is fixedly connected to a dust removal box 4, the air inlet 6 is connected to the inside of the dust removal box 4, the inner side surfaces of the dust removal box 4 are respectively fixedly connected to a main partition plate 8 and a secondary partition plate 9, and the main partition plate 8 is movably connected to a mounting plate 7 through a positioning plate 14, and a filter screen 10 is fixedly connected to a mounting groove of the mounting plate 7, and at the same time, the inner side surface of the dust removal box 4 is fixedly connected to a retention layer 15, and the upper surface of the dust removal box 4 away from the air pump 5 is connected to the inner cavity of the partition plate 2 through a through hole.

[0019] In this embodiment, when the cabinet 1 of the low-voltage control cabinet needs to dissipate heat, the switch of the air pump 5 is started, and the air pump 5 can inject the external airflow into the dust removal box 4. When the airflow flows into the dust removal box 4, it will first contact the retention layer 15 set on the surface of the main partition plate 8, and then it can partially intercept and filter the dust carried in the airflow. When the airflow moves along the path formed by the inner cavity of the dust removal box 4, the airflow will first pass through the double filtration of the filter screen 10 set in the mounting plate 7 at the turning point on one side of the dust removal box 4, and at the turning point on the other side of the dust removal box 4, it will impact the retention layer 15, so that part of the dust in the airflow can be retained in the loose and porous structure on the surface of the retention layer 15, so that the airflow passes through the passage. When the air flows into the inner cavity of the partition plate 2 through the hole, it can be subjected to multiple filtering treatments, thereby effectively improving the cleanliness of the airflow, and the filter plate 3 arranged in the partition plate 2 can perform the final auxiliary filtration on the airflow, and then the airflow can flow into the interior of the cabinet 1 through the air outlet holes on the surface of the partition plate 2. When the air pressure inside the cabinet 1 is high, the airflow will push the sealing plate 12 to move up and squeeze the spring, and the air outlet holes closed by the sealing plate 12 will be connected to the interior of the cabinet 1, so that the gas inside the cabinet 1 can flow out through the air outlet holes opened by the exhaust plate 11, thereby achieving the dust-proof and heat-dissipating effect of the low-pressure control cabinet. At the same time, when the dust box 4 needs to be cleaned, the hinged door of the cabinet 1 can be opened to quickly take out the dust box 4.

[0020] As a preferred embodiment, the dust removal box 4 is a rectangular structure, and the two sides of the inner side of the dust removal box 4 are respectively and evenly fixedly connected with the main partition plate 8 and the auxiliary partition plate 9 in parallel, and the main partition plate 8 and the auxiliary partition plate 9 are staggered. At the same time, the inner cavity of the dust removal box 4, the main partition plate 8 and the auxiliary partition plate 9 are combined together to form a bow-shaped structure.

[0021] In this embodiment, if Figure 1 and Figure 3 The cooperation between the main partition plate 8 and the auxiliary partition plate 9 enables the inner cavity of the dust removal box 4 to be set as a specific flow path, thereby improving the filtering effect of the dust removal box 4 on dust in the airflow and facilitating the installation of the dust removal structure.

[0022] As a preferred embodiment, the position of the side of the dust removal box 4 relative to the auxiliary partition plate 9 corresponds to the retention layer 15, and the retention layer 15 is a rectangular structure, and the retention layer 15 fixedly connected to the side of the main partition plate 8 relative to the air pump 5 is an L-shaped structure.

[0023] In this embodiment, if Figure 1 and Figure 3 The interception layer 15 is made of a loose and porous material, and can accordingly intercept part of the dust carried in the airflow when the airflow impacts, thereby helping to improve the dust removal effect of the dust removal box 4 on the external airflow.

[0024] As a preferred embodiment, the main partition plate 8 and the secondary partition plate 9 are both rectangular structures, and the two groups of positioning plates 14 fixedly connected to one end of the main partition plate 8 are both long strip structures. At the same time, the horizontal cross-section formed by the main partition plate 8 and the positioning plate 14 combined together is a T-shaped structure.

[0025] In this embodiment, if Figure 3 and Figure 4 The setting of the positioning plate 14 allows the mounting plate 7 to be conveniently loaded and unloaded at one end of the main partition plate 8, and can enhance the anti-impact effect of the mounting plate 7 and the filter 10 against airflow, thereby preventing the mounting plate 7 from being separated from the main partition plate 8 by the impact of airflow, and ensuring that the airflow can be fully filtered by the filter 10 when it is flowing.

[0026] As a preferred embodiment, the mounting plate 7 is of a rectangular structure, the mounting grooves opened at both ends of the mounting plate 7 are of a square structure, and the mounting plate 7 and the mounting grooves are combined together to form a Japanese-shaped structure. At the same time, a positioning groove is opened in the middle of the surface of the mounting plate 7 corresponding to the position of the positioning plate 14, and the cross-section of the positioning groove is of a convex structure.

[0027] In this embodiment, if Figure 1 and Figure 3 The size of the assembly formed by the positioning plate 14 and the main partition plate 8 is compatible with the size of the positioning groove, which can help enhance the stability of the connection between the mounting plate 7 and the main partition plate 8. At the same time, the multiple groups of mounting plates 7 in the dust removal box 4 start from the side close to the air pump 5. The farther the mounting plate 7 is from the air pump 5, the smaller the mesh of the filter screen 10 arranged inside it, thereby enhancing the dust filtering effect of the dust removal box 4.

[0028] As a preferred embodiment, the partition plate 2 has a rectangular structure, the cross-section of the partition plate 2 is a U-shaped structure, and the filter plate 3 fixedly connected to the inner cavity of the fixed plate by buckles has a square structure, and the cross-section formed by the combination of the partition plate 2 and the filter plate 3 is a U-shaped structure. At the same time, a plurality of groups of air outlets are evenly arranged on the upper surface of the partition plate 2, and the positions of the upper surface of the partition plate 2 relative to the air outlets are fixedly connected to the shielding component 13 by buckles.

[0029] In this embodiment, if Figure 1 and Figure 2 The setting of the partition plate 2 can not only make the external airflow blow into the interior of the control cabinet evenly, but also provide corresponding isolation and protection for the dust removal box 4, thereby reducing the probability of the dust removal box 4 being squeezed by the outside world. At the same time, the lower surface of the shielding component 13 facing the air outlet is a hemispherical structure, which can then help reduce the impact effect of the airflow on the shielding component 13. In addition, the setting of the shielding component 13 can also reduce the probability of dust in the cabinet 1 falling into the partition plate 2.

[0030] As a preferred embodiment, the exhaust plate 11 has a cylindrical structure, and a plurality of air outlet holes are arranged at equal intervals around the arc surface of the exhaust plate 11, and the sealing plate 12 slidingly connected inside the exhaust plate 11 has a circular structure, and the sealing layer fixed on the arc surface of the sealing plate 12 is opposite to the air outlet holes, and the sealing plate 12 has a hollow structure.

[0031] In this embodiment, if Figure 1 and Figure 2 The sealing plate 12 with a hollow structure can effectively reduce its own weight, which makes it easier for the airflow to push the sealing plate 12 upward, so that the airflow in the cabinet 1 can easily flow out from the air outlet opened in the exhaust plate 11 when the air pump 5 is working, thereby realizing the heat dissipation inside the cabinet 1. At the same time, when the cabinet 1 does not need to dissipate heat, the sealing plate 12 will be reset under the action of the spring and gravity, and the sealing plate 12 will block the air outlet opened on the surface of the exhaust plate 11 through the sealing layer, thereby preventing external dust from flowing into the cabinet 1 from the air outlet opened in the exhaust plate 11, thereby ensuring the cleanliness of the inside of the cabinet 1.

[0032] The dustproof low-voltage control cabinet of the utility model can effectively enhance the dust removal effect of the air flowing into the outside when the control cabinet dissipates heat through the cooperation of the dust removal box 4, the main partition plate 8, the auxiliary partition plate 9, the mounting plate 7, the filter screen 10, the retention layer 15 and the filter plate 3, thereby enhancing the cleanliness effect inside the control cabinet, reducing the probability of dust accumulation, and ensuring that the low-voltage control cabinet has a good heat dissipation effect.
