[0033] Working principle: When monitoring the oil and gas pipeline after production, first press the two sealing covers 1 on the flange of the oil and gas pipeline 14, pull the pull frame 7, and when the pull frame 7 rotates toward the oil and gas pipeline 14, it can drive the sliding sleeve 5 to move along the outside of the mounting column 3 toward the oil and gas pipeline 14, so as to stretch the spring 6. At the same time, when the sliding sleeve 5 moves toward the oil and gas pipeline 14, it can drive the clamping frame 9 to move toward the oil and gas pipeline 14, and move the clamping frame 9 away from the oil and gas pipeline 14. When the clamping frame 9 moves to the flange, the clamping frame 9 is rotated in the direction close to the oil and gas pipeline 14, and the clamping frame 9 is clamped at the flange. At this time, the pulling frame 7 is released. After the pulling frame 7 is released, the spring 6 begins to contract, thereby giving the fixing block 4 a force away from the oil and gas pipeline 14, thereby giving the clamping frame 9 a force away from the oil and gas pipeline 14, and then the clamping frame 9 can be tightly pulled to the flange. When the four clamping frames 9 are pulling the flange, they can be The sealing cover 1 is tightly mounted on the oil and gas pipeline 14, so no bolts are needed during installation, and the bolts will not be stripped due to continuous disassembly of the bolts, which will then lead to difficulties in disassembly and installation. At this time, the connecting pipe 10 on one of the sealing covers 1 is threadedly connected to the ventilation pipe 11, and the other connecting pipe 10 is tightened with a sealing bolt, so that a sealed space can be formed, and the air pump 12 is started. After the air pump 12 is started, it can inflate the interior of the sealing cover 1, and then the interior of the oil and gas pipeline 14 can be filled with gas. After a period of time, when the index of the barometer 15 is stable, it can be monitored that there is no leakage in the oil and gas pipeline 14. If the index of the barometer 15 is still not stable after a long period of time, it means that the oil and gas pipeline 14 is leaking, and the double-headed motor 1303 can be started at the same time. The rotation of the two output ends of the double-headed motor 1303 can drive the power wheel 1304 to rotate, thereby driving the air pump 12 to move, and then there is no need to manually pull the monitoring device for monitoring, thereby saving time and effort and reducing the workload of users.
