The monitoring component 94 comprises a sliding ring 941, a supporting elastic block 942, a connecting pipe 943, a detection column 944, a resistance strip 945 and a conductor block 946. The supporting elastic block 942 is fixedly installed at the bottom end of the extrusion groove 911. The top end of the supporting elastic block 942 is fixedly connected with the sliding ring 941. The sliding ring 941 is slidingly and sealingly installed in the extrusion groove 911, and the top end of the sliding ring 941 penetrates and extends out of the support ring 91.

[0042] The working principle of the second embodiment of the present application is as follows:

[0044] In the process of fixing the sealing cover 8, the sealing ring 82 and the screen frame 3 by the fixing bolt 92 and the fixing nut 93, the edge of the bottom end of the sealing cover 8 extrudes the sliding ring 941 on the support ring 91, the sliding ring 941 extruded as a whole slides into the extrusion groove 911 of the support ring 91, the sliding ring 941 pushes the insulating transmission liquid in the extrusion groove 911, the insulating transmission liquid in the extrusion groove 911 enters the bottom end of the detection column 944 through the connecting pipe 943, the insulating transmission liquid entering the detection column 944 pushes the conductor block 946 to move upwards, changes the contact position of the conductor block 946 and the resistance strip 945, in the process of use, the current of the circuit in the resistance strip 945 is monitored by the control system, if the fixing bolt 92 and the fixing nut 93 are loosened due to vibration in the process of long-term use, the extrusion amount of the sealing cover 8 to the sliding ring 941 is reduced, in the process of vibration, the elastic support spring block 942 pushes the sliding ring 941 to move upwards, the insulating transmission liquid in the detection column 944 flows back to the extrusion groove 911 through the connecting pipe 943, at this time, the contact position of the conductor block 946 and the resistance strip 945 changes, the control system monitors that the current in the resistance strip 945 changes, if the change amount is within the error range, it shows that the fixing bolt 92 and the fixing nut 93 are loosened to a certain extent, but it does not affect the sealing of the sealing ring 82 to the sealing cover 8 and the screen frame 3, if the change amount is not within the error range, it shows that the fixing bolt 92 and the fixing nut 93 are loosened, the sealing of the sealing cover 8 and the screen frame 3 needs to be maintained, at this time, the control system issues an alarm to remind the staff to maintain, to prevent the sealing of the sealing cover 8 and the screen frame 3 from being loosened to cause the leakage of volatile gas.

[0045] In the process of fixing, the fixing nut 93 is clamped into the nut groove 33 of the screen frame 3, when the sealing cover 8, the sealing ring 82 and the screen frame 3 are fixed by the fixing bolt 92 and the fixing nut 93, the sealing cover 8 extrudes the sliding ring 941, the sliding ring 941 moves downwards to push the insulating transmission liquid in the extrusion groove 911, the insulating transmission liquid enters the detection column 944 through the connecting pipe 943, and when the conductor block 946 moves upwards, the conductor block 946 moves upwards to drive the display column 947 and the connecting rod 95 to move synchronously, until the connecting rod 95 clamped into the fixing groove 931, the connecting rod 95 further fixes the fixing nut 93, to prevent the fixing nut 93 from rotating to cause the loosening of the fixing bolt 92 and the fixing nut 93.
