Description

Technical Field

[0001] This utility model relates to the field of gas-insulated switchgear technology, specifically a sealing structure for a gas-insulated switchgear. Background Technology

[0002] The insulation performance of gas-insulated switchgear relies entirely on the insulating gas medium and insulation pressure sealed in the gas chamber. Once a leak occurs, the pressure inside the gas chamber decreases, and the insulation performance will drop significantly, potentially causing insulation accidents, resulting in large-scale power outages and equipment malfunctions, and even endangering personnel safety. Every year, accidents such as switch explosions and burnouts caused by decreased insulation performance result in huge economic losses. When using gas-insulated switchgear, the external pipe connections also need to maintain a sealing effect to improve the safety of switchgear use. Therefore, a sealing structure for gas-insulated switchgear is required.

[0003] The existing sealing structure of a gas-insulated switchgear cannot effectively seal the pipe connections during operation, nor can it clamp and fix the connected pipes at the sealing points of the switchgear to prevent them from falling off. Therefore, there is an urgent need for a new sealing structure for gas-insulated switchgear. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a sealing structure for a gas-insulated switchgear, so as to solve the problem that the existing sealing structure of the gas-insulated switchgear cannot effectively seal the pipe connection position of the switchgear during use, and cannot clamp and fix the connected pipe at the sealing position of the pipe of the theater electrical switchgear to prevent it from falling off.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for a gas-insulated switchgear, comprising a collar and a retaining ring. A retaining ring is installed at the upper end of the collar, and a groove is formed at the upper end of the retaining ring. A sealing rubber ring is installed at the lower end of the retaining ring. An upper limiting frame is installed at the upper end of the retaining ring. A left adjusting rod is installed at one end of the upper limiting frame, and a left clamping frame is installed at one end of the left adjusting rod. A right adjusting rod is installed at the other end of the upper limiting frame, and a right clamping frame is installed at one end of the right adjusting rod. A lower limiting frame is installed at the lower end of the collar.

[0006] Preferably, the collar is threadedly connected to the retaining ring, and the retaining ring is tightly fitted to the sealing rubber ring.

[0007] Preferably, the upper limiting frame is connected to the stabilizing ring by a slot, and the upper limiting frame and the lower limiting frame are the same size.

[0008] Preferably, the left clamping frame forms a telescopic structure with the upper limiting frame via the left adjusting rod, and the left clamping frame is engaged with the left adjusting rod.

[0009] Preferably, the right-end clamping frame forms a telescopic structure with the upper-end limiting frame via the right-end adjusting rod, and the right-end clamping frame and the right-end adjusting rod are engaged and connected. Preferably, the right clamping frame is the same size as the left clamping frame, and the right clamping frame is made of rubber material.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a collar, a retaining ring, a groove, and a sealing rubber ring, can seal the connection position through the sealing rubber ring installed at the lower end of the retaining ring in the device. By twisting and fixing the collar and the retaining ring, the connection position of the collar and the retaining ring compresses the sealing rubber ring. After fixing, it can keep the position of the connecting pipe at the connection position of the insulated switch cabinet blocked and sealed.

[0011] 2. This utility model, through the setting of an upper limiting frame, a left adjusting rod, a left clamping frame, a right adjusting rod, a right clamping frame, and a lower limiting frame, allows for the adjustment of the left and right distances of the clamping frames by means of the adjusting rods in the device. After adjustment, the pipe passing through the inside of the collar can be clamped from both the upper and lower ends, maintaining the connection stability of the pipe during connection and preventing it from falling off.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0015] The embodiments of this utility model will be described below based on its overall structure.

[0016] Please see Figures 1-4 A sealing structure for a gas-insulated switchgear includes a collar 1 and a retaining ring 2. The retaining ring 2 is installed on the upper end of the collar 1, and a groove 3 is provided on the upper end of the retaining ring 2. The collar 1 and the retaining ring 2 are threaded together, and the retaining ring 2 is tightly fitted with a sealing rubber ring 4. The collar 1 in the device can be screwed to connect and abut against the retaining ring 2. When abutting, it can compress the sealing rubber ring 4 to maintain the sealing effect at the connection position. The sealing rubber ring 4 is installed on the lower end of the retaining ring 2, and an upper limit frame 5 is installed on the upper end of the retaining ring 2. A left adjusting rod 6 is installed on one end of the upper limit frame 5. The upper limit frame 5 is engaged with the retaining ring 2 through the groove 3, and the upper end... The limiting frame 5 and the lower limiting frame 10 are the same size. The right clamping frame 9 forms a telescopic structure with the upper limiting frame 5 through the right adjusting rod 8. The right clamping frame 9 and the right adjusting rod 8 are engaged and connected. The clamping frames inside the upper limiting frame 5 and the lower limiting frame 10 installed at the upper and lower ends of the device move back and forth through the adjusting rod to squeeze and fix the pipe connection position to prevent the pipe from falling off. The left clamping frame 7 is installed at one end of the left adjusting rod 6, the right adjusting rod 8 is installed at the other end of the upper limiting frame 5, the right clamping frame 9 is installed at one end of the right adjusting rod 8, and the lower limiting frame 10 is installed at the lower end of the collar 1.

[0017] Working principle: In use, firstly, the upper limiting frame 5 is installed and connected through the slot 3 at the upper end of the stabilizing ring 2 in the device. Then, the lower limiting frame 10 is connected and installed at the lower end of the collar 1. After installation, the collar 1 is turned to make contact with the stabilizing ring 2. After contact, the sealing rubber ring 4 at the lower end of the stabilizing ring 2 is squeezed, thus maintaining a seal after connection. After connection is completed, the pipe for the insulating electrical cabinet is passed through the entire mechanism, and the device is fitted onto the pipe. After fitting, depending on the pipe diameter, the left and right adjusting rods 6 and 8 in the device can be used to move the left and right clamping frames 7 and 9 respectively, thus preventing the connection of the pipe from falling off.
