Description

Technical Field

[0001] This utility model relates to a sealing device for an inflatable cabinet, belonging to the technical field of inflatable cabinets. Background Technology

[0002] The sealing device of a gas-insulated switchgear is a key technology to ensure the long-term stable and airtight sealing of insulating gas. To ensure the reliability of the seal, the sealing surface of the sealing plate must be polished without scratches, and the sealing groove must be dust-free. Most gas-insulated switchgear seals on the market use aluminum profiles because of their low density and ease of processing. The flatness, material strength, and smoothness can also better meet the sealing requirements. However, the cost of using aluminum profile seals is high, and they are easily scratched during handling and assembly, affecting the appearance of the product. Therefore, a sealing device that can meet functional requirements and is easy to assemble is needed for gas-insulated switchgear. Utility Model Content

[0003] The purpose of this invention is to provide a sealing device for an inflatable cabinet to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sealing device for an inflatable cabinet, comprising an inflatable cabinet body and a sealing plate. The side wall of the inflatable cabinet body has an installation port. The inner side of the sealing plate is provided with a sealing groove that matches the installation port. The sealing groove is used to install a sealing ring, and multiple reinforcing ribs are integrally formed in the sealing groove. The sealing plate is fixed to the side wall of the inflatable cabinet body and seals the installation port through the cooperation of the sealing groove and the sealing ring. At least one support plate is provided on the outer side of the sealing plate in the horizontal direction, and the edge of the sealing plate is integrally formed with an outwardly facing flange structure.

[0005] Preferably, the sealing plate has multiple mounting holes, which are evenly spaced along the outer periphery of the sealing groove. Each mounting hole is fitted with a stud, and the sealing plate is fixed to the gas cabinet body by the stud.

[0006] Preferably, the sealing plate is made of stainless steel, and the inner side of the sealing plate is a stainless steel mirror surface.

[0007] Preferably, the thickness of the sealing plate is 3mm.

[0008] Preferably, the sealing groove, reinforcing ribs, and flange structure on the sealing plate are all integrally formed by die casting.

[0009] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0010] 1. This utility model abandons the traditional aluminum profile sealing structure and adopts a stainless steel sealing plate, which reduces the thickness and weight of the sealing plate, makes assembly more convenient, and saves material costs. By setting reinforcing ribs, support plates and flange structures on the stainless steel sealing plate, the structural strength of the sealing plate is greatly enhanced, effectively avoiding the air leakage problem caused by the deformation of the sealing plate under pressure, and providing a guarantee for the stable operation of the gas cabinet.

[0011] 2. The sealing plate is formed by die casting, which can reduce some processing costs, improve product consistency, and avoid air leakage caused by insufficient smoothness of the sealing groove or the presence of air bubbles, thus further improving the sealing effect.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] As attached Figure 1-4 As shown, the sealing device of the gas cabinet of this utility model includes a gas cabinet body 1 and a sealing plate 2. The side wall of the gas cabinet body 1 has an installation port 3, which is used for workers to install internal parts of the gas cabinet body 1 and for subsequent maintenance.

[0020] The inner side of the sealing plate 2 is provided with a sealing groove 4 that matches the mounting port 3. The sealing groove 4 is used to install the sealing ring 5. The width and depth of the sealing groove 4 match the sealing ring 5 to ensure that the sealing ring 5 can fit tightly against the groove wall after being embedded. Multiple reinforcing ribs 6 are integrally formed in the sealing groove 4. In this embodiment, there are two reinforcing ribs 6, which are symmetrically arranged in the sealing groove 4 on both sides of the sealing plate 2 to enhance the structural rigidity of the sealing groove 4 area and avoid deformation of the sealing groove 4 due to changes in the internal air pressure of the gas cabinet body 1 during long-term use, which would affect the sealing effect. In actual use, the number of reinforcing ribs 6 can be adjusted according to the length of the sealing groove 4.

[0021] The sealing plate 2 is fixed to the side wall of the gas cabinet body 1 and seals the installation port 3 through the cooperation of the sealing groove 4 and the sealing ring 5. Specifically, the sealing plate 2 has multiple installation holes 9, which are evenly spaced along the outer periphery of the sealing groove 4. Each installation hole 9 is fitted with a stud 10. The sealing plate 2 is fixed to the gas cabinet body 1 by the studs 10 to form a seal on the installation port 3 of the gas cabinet body 1. The evenly spaced studs 10 ensure that the sealing plate 2 is subjected to uniform force, avoids excessive local pressure that could cause deformation of the sealing plate 2, and facilitates individual tightening by operators, reducing assembly difficulty.

[0022] In this embodiment, the sealing plate 2 is made of stainless steel with a thickness of 3mm. By replacing the traditional aluminum profile sealing structure with stainless steel sheet, the thickness of the sealing plate 2 can be reduced by half, thereby reducing material costs. At the same time, due to the high structural strength of stainless steel sheet, deformation during assembly or handling can be avoided, thus ensuring the appearance of the product. In addition, the inner side of the sealing plate 2 is stainless steel mirror surface, and the surface scratches are eliminated through polishing to reduce the gap when the sealing plate 2 contacts the outer wall of the gas chamber body 1, thereby improving the sealing accuracy.

[0023] Furthermore, at least one support plate 7 is provided on the outer side of the sealing plate 2 in the horizontal direction. In this embodiment, there is one support plate 7, which is fixed to the outer side of the sealing plate 2 by welding, thereby further improving the rigidity of the sealing plate 2 and preventing deformation.

[0024] Furthermore, the edge of the sealing plate 2 is integrally formed with an outward-facing flange structure 8. On the one hand, this can prevent the sharp edges of the sealing plate 2 from scratching the operators and improve assembly safety. On the other hand, it can enhance the deformation resistance of the edge of the sealing plate 2 and ensure the fit between the sealing plate 2 and the side wall of the cabinet.

[0025] Among them, the sealing groove 4, reinforcing rib 6 and flange structure 8 on the sealing plate 2 are all integrally formed by die casting to ensure the consistency of the sealing plate 2 and prevent problems such as insufficient smoothness of the sealing groove 4 or the presence of air bubbles that cause air leakage.

[0026] In summary, this application abandons the traditional aluminum profile sealing structure and adopts a stainless steel sealing plate 2, which reduces the thickness and weight of the sealing plate 2, making assembly more convenient and saving material costs. By setting reinforcing ribs 6, support plates 7 and flange structures 8 on the stainless steel sealing plate 2, the structural strength of the sealing plate 2 is greatly enhanced, effectively avoiding air leakage caused by the deformation of the sealing plate 2 under pressure, and providing a guarantee for the stable operation of the gas-filled cabinet.

[0027] Meanwhile, the sealing plate 2 is formed by die casting, which can reduce some processing costs and has better product consistency. It can also avoid the problem of air leakage caused by insufficient smoothness or air bubbles in the sealing groove 4, thus further improving the sealing effect.

[0028] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
