SF6 gas has excellent arc extinguishing performance, insulation performance, and good chemical stability. Therefore, SF6 gas can be used as the arc extinguishing medium of high-voltage circuit breakers. During the transportation of SF6 gas, it is necessary to ensure the safety of the transportation process, monitor the gas leakage situation, prevent gas leakage from causing danger, and at the same time help reduce waste.

[0026] The following will further illustrate the present utility model in conjunction with the attached Figures 1-5 drawings.

[0027] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a quickly installable on-line SF6 gas leakage monitoring device.

[0028] In a specific technical solution, it includes two symmetrically installed gas pipelines 1 and a detachable sealing assembly 2;

[0029] As Figures 1-5 shown, the detachable sealing assembly 2 is installed outside the two gas pipelines 1. The detachable sealing assembly 2 is used to wrap the gas at the connection part of the two gas pipelines 1. The detachable sealing assembly 2 includes a first sealing cylinder 201 and a second sealing cylinder 202 sleeved outside the two gas pipelines 1. The first sealing cylinder 201 and the second sealing cylinder 202 can wrap the connection part of the two gas pipelines 1. The second sealing cylinder 202 is rotatably connected to the first sealing cylinder 201. Gaskets 203 and 204 which are sleeved outside the gas pipeline 1 and are opposite are respectively fixedly installed at the ports of the first sealing cylinder 201 and the second sealing cylinder 202. The gaskets 203 and 204 can increase the sealing performance of the connection between the first sealing cylinder 201 and the second sealing cylinder 202. A connecting rod 205 is fixedly installed on the outer wall of the first sealing cylinder 201. The connecting rod 205 can facilitate the connection with a snap ring 206. A snap ring 206 which is rotatably installed on the outer wall of the second sealing cylinder 202 and is clamped with the connecting rod 205 is connected to the connecting rod 205, which can make the fixation between the second sealing cylinder 202 and the first sealing cylinder 201 more reliable.

[0030] The first sealing cylinder 201 and the second sealing cylinder 202 are sleeved at the connection of the two gas pipelines 1. The first sealing cylinder 201 and the second sealing cylinder 202 can wrap the connection of the two gas pipelines 1. The gaskets 203 and 204 surround the outside of the two gas pipelines 1, making the opening of the snap ring 206 face the connecting rod 205. By rotating the snap ring 206, the opening of the snap ring 206 is clamped with the outside of the connecting rod 205. The snap ring 206 squeezes the connecting rod 205. The snap ring 206 gives a pulling force to the second sealing cylinder 202. The second sealing cylinder 202 gives a squeezing force to the gasket 204. The gasket 204 squeezes the gasket 203 and the outer wall of the gas pipeline 1. The outer wall of the gas pipeline 1 squeezes the gasket 203. The gasket 203 squeezes the first sealing cylinder 201, which can increase the sealing performance between the gaskets 203 and 204 and the gas pipeline 1, prevent the gas leaking from the connection of the two gas pipelines 1 from leaking through the gap between the gaskets 203 and 204 and the gas pipeline 1, and can facilitate the monitoring of the gas condition at the connection of the two gas pipelines 1.

[0031] As Figures 1-5As shown, a detection component 3 is installed on one side of the detachable sealing component 2. The detection component 3 is used to monitor gas. The detection component 3 includes a connecting pipe 301 fixedly connected to the first sealing cylinder 201 and a detector 302. The connecting pipe 301 can receive the gas in the first sealing cylinder 201, and the detector 302 can monitor the gas. A connector 303 penetrating the side wall of the detector 302 is fixedly installed at the end of the connecting pipe 301 away from the first sealing cylinder 201. The connector 303 can connect the connecting pipe 301 and the detector 302. A third gasket 304 is installed between the connector 303 and the detector 302, and the third gasket 304 can increase the sealing performance between the connector 303 and the detector 302.

[0032] There is a cavity between the first sealing cylinder 201 and the second sealing cylinder 202. The cavity between the first sealing cylinder 201 and the second sealing cylinder 202 can communicate with the connecting pipe 301. The gas between the first sealing cylinder 201 and the second sealing cylinder 202 can enter the connecting pipe 301, and the gas in the connecting pipe 301 can enter the detector 302 through the connector 303. After the detector 302 is started, it can monitor the gas. When an alarm is issued on the detector 302, it means that there is SF6 gas leakage at the connection between the two gas transmission pipes 1. When the detector 302 does not issue an alarm, it is necessary to promptly handle the gas transmission pipe 1 with leaked SF6 gas, indicating that there is no SF6 gas leakage at the connection of the two gas transmission pipes 1.

[0033] As Figures 1-3 As shown, a box body 4 is installed outside the detection component 3. The box body 4 can store the detachable sealing component 2 and the detection component 3. A groove 5 is opened in the box body 4. The groove 5 can fix the first sealing cylinder 201, the second sealing cylinder 202, the connecting pipe 301, the detector 302 and the connector 303. The first sealing cylinder 201, the second sealing cylinder 202, the connecting pipe 301, the detector 302 and the connector 303 are all clamped in the groove 5. After use, by rotating the first sealing cylinder 201, the second sealing cylinder 202, the connecting pipe 301 and the connector 303, the first sealing cylinder 201, the second sealing cylinder 202 and the connecting pipe 301 can be clamped in the groove 5. Closing the box body 4 can store the detachable sealing component 2 and the detection component 3, which is convenient for carrying the monitoring device.

[0034] As Figures 1-3 As shown, a lock 6 is fixedly installed outside the box body 4. The lock 6 can lock the box body 4 and improve the security of the box body 4.

[0035] As Figures 1-3 As shown, a handle 7 is fixedly installed on the outer side wall of the box body 4. By lifting the handle 7, the handle 7 can drive the box body 4 to be lifted, which is convenient for carrying the monitoring device.

[0036] As Figure 5As shown, a sealing ring 8 is inserted between the first gasket 203 and the second gasket 204. When monitoring the port of a gas pipeline 1, the gas pipeline 1 is inserted into one end of the first sealing cylinder 201 and the second sealing cylinder 202, and the sealing ring 8 is inserted into the other end of the first sealing cylinder 201 and the second sealing cylinder 202, which can conveniently seal the first sealing cylinder 201 and the second sealing cylinder 202 and prevent gas from leaking from the openings of the first sealing cylinder 201 and the second sealing cylinder 202.

[0037] The standard parts used in the present utility model can all be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
