Description

Technical Field

[0001] This utility model relates to the field of electrical control box technology, and in particular to an electrical separation type electrical control box. Background Technology

[0002] Traditional electrical control boxes suffer from drawbacks due to the mixed installation of electrical and pneumatic components: valve leaks can lead to electrical short circuits; maintenance of pneumatic components requires complete power disconnection, impacting production efficiency; insufficient sealing performance allows dust / liquid to enter the electrical cavity; and the fixed valve height makes leak detection difficult. Current technologies using fixed partitions struggle to achieve dynamic sealing and lack effective leak guidance mechanisms. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problem that leakage of air valves may cause electrical short circuits and that the pneumatic components need to be completely de-energized during maintenance, thus affecting production efficiency, an electrical separation type control box is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an electrical separation type electrical control box, including a box body and a partition component. The box body has a cavity, and the partition component divides the cavity inside the box body into an electrical installation cavity and a valve installation cavity. The partition component includes a partition plate and a mounting plate arranged around the partition plate. The mounting plate and the partition plate are fixedly connected. A receiving groove is opened on the side of the mounting plate near the inner wall of the box body. A sealing strip that can be elastically deformed is arranged in the receiving groove. The sealing strip protrudes from the surface of the mounting plate. The end of the partition plate near the valve installation cavity has a guide surface that is recessed towards the electrical installation cavity. Through double isolation (physical separation + elastic sealing), an IP54 or higher protection level is achieved. The guide surface design causes leaked gas to converge in a directional manner, avoiding impact on the connection between the mounting plate and the box body, and reducing the risk of electrical component failure.

[0005] To address the issue of unstable partition installation and susceptibility to vibration, the installation plate is further designed to have a lateral width greater than that of the partition plate.

[0006] To address the issue of single sealing strips being prone to aging and failure, a further improvement is made by creating two sealing groove groups on the side of the mounting plate near the inner wall of the housing, with the sealing strip located between the two sealing groove groups.

[0007] To address the corrosion problem caused by residual water vapor carried in the gas, the bottom of the valve mounting cavity is further lower than the bottom of the electrical appliance mounting cavity.

[0008] Further, the sealing strip is made of one of silicone rubber, fluororubber, or EPDM rubber, and the cross-section of the sealing strip is one of trapezoidal, rectangular, or semi-circular.

[0009] To address the issue of repeated disassembly and reassembly required for valve testing, and the fact that adjacent valves at the same height can easily interfere with each other and cause misjudgments, a further solution is proposed: a valve adjustment assembly is arranged within the valve mounting cavity. This assembly controls the height of the valve and includes a slide rail, a matching slide base, and two clamping blocks. The slide rail extends vertically, and the slide rail and slide base are slidably connected. The clamping blocks are slidably arranged on the slide base, and the two clamping blocks can move closer or further apart to clamp the valve.

[0010] To address the issue of low positioning accuracy of the clamping block, the design further includes a slide rail on the slide block, on which the clamping block is slidably arranged.

[0011] To address the issue of easy loosening of mechanical clamps, a further improvement is made by arranging magnets on the clamping blocks, with the magnetic poles of the magnets on the two clamping blocks arranged in opposite directions.

[0012] The beneficial effects of this utility model are: the electrical separation type control box provided by this utility model achieves an IP54 or higher protection level through double isolation (physical separation + elastic sealing); the guide surface design makes the leaked gas converge in a directional manner, avoiding impact on the connection between the mounting plate and the box body, and reducing the risk of electrical component failure.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] like Figure 1 This is a schematic diagram of the structure of this utility model, an electrical separation type electrical control box, including a box body 1 and a partition component 2. The box body 1 has a cavity, and the partition component 2 divides the cavity inside the box body 1 into an electrical installation cavity 11 and a valve installation cavity 12, as shown below. Figure 3 As shown, the partition assembly 2 includes a partition plate 21 and a mounting plate 22 arranged around the partition plate 21. The mounting plate 22 and the partition plate 21 are fixedly connected. The mounting plate 22 has a receiving groove 221 on the side near the inner wall of the housing 1. A sealing strip 23 that can be elastically deformed is arranged in the receiving groove 221. The sealing strip 23 protrudes from the surface of the mounting plate 22. The partition plate 21 has a guide surface 211 that is recessed towards the electrical installation cavity 11 at the end near the gas valve installation cavity 12. The double isolation (physical separation + elastic sealing) achieves an IP54 or higher protection level. The guide surface 211 is designed to direct the leakage gas to converge, avoid impacting the connection between the mounting plate 22 and the housing 1, and reduce the risk of electrical component failure.

[0021] For example Figure 1 As shown, the lateral width of the mounting plate 22 is greater than the lateral width of the partition plate 21. The wider mounting plate enhances the structural rigidity and improves the vibration resistance.

[0022] Two sealing groove groups 222 are provided on the side of the mounting plate 22 near the inner wall of the housing 1. The sealing strip 23 is located between the two sealing groove groups 222. The double sealing grooves form a pressure compensation cavity to extend the sealing life. The sealing groove group 222 consists of several sealing grooves. The cross-section of the sealing groove is one of V-shaped, trapezoidal, rectangular or semi-circular.

[0023] like Figure 3 As shown, the bottom of the valve mounting cavity 12 is lower than the bottom of the electrical mounting cavity 11. The height difference between the cavity bottoms creates a differential control, causing liquid to accumulate at the connection between the mounting plate 22 and the housing 1, resulting in sealing failure.

[0024] The sealing strip 23 is made of one of silicone rubber, fluororubber or EPDM rubber, and the cross-section of the sealing strip 23 is one of trapezoidal, rectangular or semi-circular.

[0025] like Figure 4As shown, an air valve adjusting assembly 3 is arranged in the air valve mounting cavity 12. The air valve adjusting assembly 3 is used to control the height of the air valve. The air valve adjusting assembly 3 includes a slide rail 31, a slide seat 32 that matches the slide rail 31, and two clamping blocks 33. The slide rail 31 extends vertically, and the slide rail 31 and the slide seat 32 are slidably connected. The clamping blocks 33 are slidably arranged on the slide seat 32. The two clamping blocks 33 can move closer or further apart. The two clamping blocks 33 can clamp the air valve, realizing tool-free height adjustment and shortening the detection time.

[0026] The slide block 32 has a slide rail 34, and the clamping block 33 is slidably arranged on the slide rail 34. The slide rail 34 guides and improves the clamping positioning accuracy. Magnets 35 are arranged on the clamping block 33. The magnetic poles of the magnets 35 on the two clamping blocks 33 are arranged oppositely. The magnetic clamping structure keeps the air valve stable under vibration conditions.

[0027] Operating principle: During installation, first press the mounting plate 22 with sealing strip 23 into the receiving groove 221, then install the partition component 2 into the housing 1. The mounting plate 22 is fixedly connected to the housing 1 with bolts. Adjust the height of the gas valve and fix it magnetically. During operation, the leaking liquid on the gas valve side releases gas pressure along the guide surface, normalizing the gas and preventing high-pressure gas from impacting the connection between the mounting plate 22 and the housing 1 and intruding into the electrical installation cavity 11. The elastic sealing strip 23 compensates for the gap caused by thermal deformation. During maintenance, the gas valve can be disassembled separately without affecting the operation of the electrical components.

[0028] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
