Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to an environmental protection device for a gas delivery control cabinet. Background Technology

[0002] In industrial production, the gas delivery control cabinet is the core control unit of the gas delivery system. Its internal electrical components, valve controllers and other precision parts have extremely high requirements for the operating environment. Explosive gases, moisture, dust, flames and sealing leaks at cable penetrations in the external environment can all cause control cabinet failure, damage and even safety accidents.

[0003] The existing gas delivery control cabinets have a simple structure. Most of them are installed and fixed with bolts and are tightly assembled with the heat dissipation structure. Personnel can only open the cabinet door to inspect the electrical components from one side, and the space for maintenance of electrical components and heat dissipation structure is limited.

[0004] An existing patent (publication number: CN222515412U) discloses a protective device for a PLC control cabinet. By setting up an adjustment isolation unit, a U-shaped support frame can be used with several electrical component mounting plates to assemble electrical components. By holding a turntable, the horizontal lead screw can be controlled to rotate forward and backward on the control cabinet body. One of the support blocks, which is threaded to the horizontal lead screw, can drive the U-shaped support frame to move and adjust under force. The other support block can slide and move on the horizontal guide rod to cooperate with the adjustment of the support frame and provide initial auxiliary support. The rectangular through groove on the surface of the control cabinet body away from the door can be used to move the support frame to the outside of the control cabinet body. Personnel can inspect and maintain the electrical components on opposite sides of the support frame. After opening the door, it is also convenient to maintain and operate the heat dissipation components in the open control cabinet body. The equipment has flexible and convenient operation for maintenance of electrical components and heat dissipation structure.

[0005] Existing patents offer solutions to the aforementioned problems, but their safety is inadequate. In actual use, due to the lack of a buffer protection structure, external impacts can easily be directly transmitted to internal electrical components and gas control valves, causing component solder joints to fall off, valve interfaces to loosen, expanding safety hazards, seriously affecting the normal operation of the device, and reducing its practicality.

[0006] Therefore, an environmental protection device for a gas delivery control cabinet is proposed. Utility Model Content

[0027] 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.

[0028] Please see Figure 1-5 The present invention provides the following technical solution:

[0029] An environmental protection device for a gas delivery control cabinet includes a cabinet 1. A movable component 2 is fixedly connected inside the cabinet 1, and a buffer mounting component 3 is fixedly connected inside the movable component 2. The buffer mounting component 3 includes a support block 301. A support plate 302 is fixedly connected to the top inside the support block 301, and a plurality of buffers 303 are fixedly connected to the bottom of the support plate 302. A mounting plate 304 is fixedly connected to the top of the support plate 302, and a plurality of wire holes 305 are provided on both sides of the mounting plate 304. H-shaped plates 306 are fixedly connected to both sides of the rear side of the mounting plate 304, and wire harness clips 307 are fixedly connected to both sides of the H-shaped plates 306.

[0030] In this embodiment: the positioning plate 201 and the latching block 203 work together to form a latching structure. Rotating the latching block 203 releases the lock on the square tube 204, allowing the U-shaped plate 205 and the square tube 204 to move smoothly under the constraint of the connecting block 202, thus smoothly moving them out of the cabinet 1 to expand the maintenance space and facilitate equipment maintenance. After the U-shaped plate 205 is reset, rotating the latching block 203 again locks it in place, achieving a tight connection between the U-shaped plate 205 and the cabinet 1, improving the ease of use of the device. Then, the device connects to the cabinet 1 through the wire hole 305. The use of wire harness clips 307 together forms a wire harness organization structure, which allows the wire harness to pass smoothly through the wire hole 305 and be fixed in the wire harness clip 307, completing the organization and fixation of the wire harness, ensuring the cleanliness of the inside of the cabinet 1, facilitating subsequent maintenance and heat dissipation. At the same time, the buffer structure formed by the buffer 303 allows the buffer 303 to deform when it encounters an impact, which can effectively buffer and disperse the external impact force, prevent component solder joints from falling off and valve interfaces from loosening, ensure the stable operation of the equipment, reduce safety hazards, and improve the practicality of the device.

[0031] Specifically, such as Figure 4 As shown, the moving component 2 includes a positioning plate 201. Connecting blocks 202 are fixedly connected to the right side of the front and rear sides of the positioning plate 201. A buckle block 203 is rotatably connected to the right side of the positioning plate 201. A square tube 204 is slidably connected to the surface of the positioning plate 201. A U-shaped plate 205 is fixedly connected to the top of the square tube 204. A support block 301 is fixedly connected inside the U-shaped plate 205. A temperature detector 206 is fixedly connected to the front side of the left side of the inner wall of the U-shaped plate 205.

[0032] Specifically, such as Figure 3 As shown, the bottom of the inner wall of the cabinet 1 is provided with a connecting groove 4 for use with the square tube 204, and the side of the positioning plate 201 away from the buckle block 203 is fixedly connected to the left side of the inner wall of the connecting groove 4.

[0033] Specifically, such as Figure 4 As shown, the front and rear sides of the inner wall of the square tube 204 are provided with movable grooves 5 for use with the connecting block 202, and the surface of the connecting block 202 is in contact with the inner wall of the movable groove 5.

[0034] Specifically, such as Figure 2 , Figure 4 As shown, a rubber sealing strip 6 is fixedly connected to the right side of the surface of the U-shaped plate 205.

[0035] In this embodiment: the square tube 204 moves smoothly under the constraint of the connecting block 202 by the cooperation of the connecting block 202 and the moving groove 5. Combined with the connecting groove 4 to form a bidirectional guiding structure, the U-shaped plate 205 can move smoothly, avoiding deviation or jamming. This greatly expands the maintenance and operation space and facilitates equipment maintenance. At the same time, the sealing structure formed by the rubber sealing strip 6 can fill the gap between the U-shaped plate 205 and the cabinet 1, forming an efficient sealing environment to prevent external moisture and dust from entering the cabinet 1, ensuring the stable operation of the equipment and improving the ease of use of the moving component 2.

[0036] Specifically, such as Figure 5 As shown, several heat sinks 7 are fixedly connected to the rear side of the mounting plate 304.

[0037] Specifically, such as Figure 2 , Figure 3 As shown, the top of the front and rear sides of the cabinet 1 are provided with connection holes 8, and a perforated plate 9 is fixedly connected inside the connection holes 8.

[0038] In this embodiment: the connection hole 8 and the perforated plate 9 are used together to form a heat dissipation structure, which allows the air in the cabinet 1 to dissipate heat steadily. Combined with the heat conduction structure of the heat sink 7, the temperature of the electronic components can be quickly dissipated. The two work together to achieve efficient heat dissipation of the equipment, ensure the stable operation of the equipment, and improve the stability of the device.

[0039] Specifically, such as Figure 3 As shown, the top of the cabinet 1 is fixedly connected to the box 10, and several ventilation holes 11 are provided at the four corners of the top surface of the box 10. The bottom of the box 10 is provided with four mounting holes 12, and a cooling fan 13 is fixedly connected inside the mounting holes 12. The top of both sides inside the box 10 is movably connected to the sliders 14, and a filter box 15 is fixedly connected between the opposite sides of the two sliders 14. The top of the filter box 15 is movably connected to the filter frame 16, and a desiccant is provided inside the filter box 15.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a controller 17 is fixedly connected to the front side of the cabinet 1, and the controller 17 is electrically connected to the cooling fan 13 and the temperature detector 206.

[0041] Specifically, such as Figure 1 , Figure 2 As shown, a fixed bracket 18 is fixedly connected to the bottom of the cabinet 1, and triangular reinforcing plates 19 are fixedly connected to the four corners of the cabinet 1.

[0042] In this embodiment: the fixed bracket 18 ensures the device remains stable on most common surfaces. Combined with the rigid reinforcement structure formed by the triangular reinforcing plate 19, it effectively blocks external impacts, ensuring stable operation. Simultaneously, the controller 17 allows for setting the device's operation according to actual conditions. Based on the temperature detector 206, the operating parameters of the cooling fan 13 are adjusted, allowing outside air to flow sequentially through the ventilation holes 11, filter frame 16, and filter box 15 into the cabinet 1, achieving efficient heat dissipation and improving the device's practicality. Furthermore, the slider 14, working in conjunction with the filter box 15, not only blocks impurities in the air in real time, ensuring clean air entering the cabinet 1, but also allows the filter box 15 to move smoothly under the constraint of the slider 14, cleaning impurities and enhancing the device's ease of use.

[0043] Working Principle: When controlling gas delivery, the device first uses the support structure of the fixed bracket 18 to maintain stability on most common surfaces. Combined with the rigid reinforcement structure formed by the triangular reinforcing plate 19, it effectively blocks external impacts, ensuring stable operation. Next, rotating the latch block 203 releases the lock on the square tube 204, allowing it to move smoothly under the constraint of the connecting block 202. Simultaneously, this makes the U-shaped plate 205 move more smoothly, allowing it to smoothly move out of the cabinet 1, expanding the maintenance space and facilitating equipment maintenance and inspection. Together with the wire hole 305 and the wire harness clip 307, a wire harness organization structure is formed, achieving cable neatness and fixation. After maintenance, the U-shaped plate 205 is reset, and the latch block 203 is rotated to lock the U-shaped plate 205 and the square tube 204, realizing the U-shaped plate 205's secure movement. The board 205 is tightly connected to the cabinet 1 to prevent electronic components from shaking and ensure stable operation of the equipment. During operation, the operator sets the operating parameters of the device through the controller 17. The temperature detector 206 can detect the temperature change inside the cabinet 1 in real time and transmit the data to the controller 17. The operating parameters of the cooling fan 13 are then set so that outside air flows into the cabinet 1 through the ventilation hole 11, filter frame 16, and filter box 15 in sequence, and then evaporates through the perforated plate 9 to achieve efficient heat dissipation. At the same time, the desiccant inside the filter box 15 ensures that the inside of the cabinet 1 is dry. When subjected to external impact, the buffer 303 deforms and disperses the impact force, which can effectively weaken the impact force transmitted to the electrical components, prevent component solder joints from falling off and valve interfaces from loosening, and reduce safety hazards.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
