[0022] See also Figure 1 , Figure 2 , Figure 4 The connecting mechanism 8 includes an insert block 81, the inner side of the connecting frame 4 is slidably sleeved with the insert block 81, the outer side of the insert block 81 is fixedly connected with a slide seat 82, the slide seat 82 contacts the connecting frame 4, the slide seat 82 is slidably connected to the fixed seat 2, the outer side of the slide seat 82 is fixedly connected with a pull rod 83, the inner side of the slide seat 82 is fixedly connected with a magnetic block 84, the outer side of the magnetic block 84 is fixedly connected with a connecting rod 85, the magnetic block 84 and the connecting rod 85 are both slidably connected to the fixed seat 2, and a spring 86 is arranged on the outer side of the connecting rod 85, one end of the spring 86 is fixedly connected to the magnetic block 84, and the other end of the spring 86 is fixedly connected to the fixed seat 2. By designing the spring 86, the force of the spring 86 can act on the magnetic block 84. By designing the connecting mechanism 8, the installation of the monitoring box 5 is convenient.

[0023] See also Figure 1 , Figure 4 , Figure 5The pressure relief mechanism 9 includes a motor 91, which is fixedly connected to the inside of the monitoring box 5, and a screw 92 is fixedly connected to the lower end of the output end of the motor 91. The bottom of the screw 92 is rotatably connected to a fixed block 93 through a bearing, and the top of the fixed block 93 is fixedly connected to a guide rod 94. A plug 95 is slidably sleeved on the outside of the guide rod 94, and a sealing ring 96 is slidably sleeved on the outside of the guide rod 94.

The sealing ring 98 is fixedly connected to the pipeline 1. By designing the sealing ring 98, the connection between the connecting pipe 97 and the pipeline 1 can be sealed. A filter screen 99 is arranged inside the monitoring box 5. By designing the pressure relief mechanism 9, the pressure inside the pipeline 1 can be relieved.

[0024] Working principle: during use, when the monitoring box 5 needs to be installed, first pull the pull rod 83 horizontally, the pull rod 83 drives the slide 82 and the magnetic block 84 to move, the magnetic block 84 drives the connecting rod 85 to move, the magnetic block 84 squeezes the spring 86, and then slides the slider 3 into the fixed seat 2, so that the monitoring box 5 moves down and contacts the pipeline 1. At the same time, the monitoring head 6 and the connecting pipe 97 will be inserted into the pipeline 1. Then release the pull rod 83, and the elastic action of the spring 86 will give a reaction force to the magnetic block 84, and the magnetic block 84 will drive the slide 82 and the plug block 81 to reset, so that the plug block 81 is inserted into the connecting frame 4. Through the sliding connection between the slider 3 and the fixed seat 2, the horizontal direction of the monitoring box 5 can be limited. At the same time, the vertical direction of the connecting frame 4 can be limited by plugging the plug block 81 with the connecting frame 4, so that the monitoring box 5 can be installed and fixed. The installation process does not require the help of other work, and the installation is convenient and quick.

[0025] When the monitoring box 5 detects that the internal pressure of the pipeline 1 is relatively high, the motor 91 is controlled and started. The motor 91 drives the screw 92 to rotate to realize the threaded movement of the plug 95. The plug 95 moves down along the guide rod 94. The plug 95 moves and separates from the connecting pipe 97. At this time, the internal gas of the pipeline 1 can enter the monitoring box 5 through the connecting pipe 97, and the gas is finally discharged through the filter 99, which can prevent the internal gas pressure of the pipeline 1 from being too high and causing danger.
