As shown in fig. 6, when the two moving units move close to each other, the two third arc-shaped electric sliding rails 301 are also contacted with each other to form an annular sliding rail, the rear third arc-shaped electric sliding rail 301 drives the second arc-shaped electric sliding block 302, the third mounting plate 303, the second spring telescopic rod 304, the mounting block 305 and the second cleaning plate 306 to move until the second cleaning plate 306 is contacted with the diversion pipeline of the petrochemical pipeline 6, then the second arc-shaped electric sliding block 302 is controlled to be started to perform circular motion on the arc-shaped sliding rails, the second arc-shaped electric sliding block 302 drives the third mounting plate 303, the second spring telescopic rod 304, the mounting block 305 and the second cleaning plate 306 to move, and when the second cleaning plate 306 rotates, the dirt on the outer surface of the diversion pipeline 6 is cleaned, so that the dirt on the surface of the pipeline is prevented from being blown to the joint; the lower part of the second cleaning plate 306 is in contact with the outer surface of the main pipeline of the petrochemical pipeline 6, the main pipeline can be forced to compress the second spring telescopic rod 304 when the second cleaning plate 306 rotates, so that the second cleaning plate 306 moves along the outer surface of the shunt pipeline of the petrochemical pipeline 6, the moving track of the second cleaning plate 306 is the same as the shape of the joint of the main pipeline of the petrochemical pipeline 6 and the shunt pipeline, and the second cleaning plate 306 can clean the joint of the main pipeline of the petrochemical pipeline 6 and the shunt pipeline; as shown in fig. 8, one end of a monitoring optical cable is inserted into the left interface of the monitor 501 and then wound on a winding roller 505, after dirt on the outer surface of the main pipeline of the petrochemical pipeline 6, the outer surface of the shunt pipeline and the joint of the main pipeline and the shunt pipeline is cleaned, an operator sequentially winds the optical cable around a U-shaped block 507 and a pressing block 406, and then places the end of the optical cable between a clamping plate 401 and an installation block 305, as shown in fig. 6-7, due to the action of a torsion spring rotating shaft, the clamping plate 401 and the installation block 305 clamp the end of the optical cable, then the second arc-shaped electric slider 302 is continuously controlled to move for a circle, the installation block 305 follows to move to wind the optical cable on the shunt pipeline of the petrochemical pipeline 6, the optical cable is divided into a flat shape and a column shape, when a flat optical cable is used, the optical cable can be twisted, so that the monitoring part of the optical cable can not be fully contacted with the petrochemical pipeline 6, thereby affecting monitoring, and in order to prevent the flat optical cable from being twisted after being wound on the shunt pipeline, therefore, the optical cable passes through the U-shaped block 507, the shape of the optical cable is limited and fixed after the optical cable passes through the U-shaped block 507, the optical cable wound on the petrochemical pipeline 6 is the same in shape, and distortion is avoided, meanwhile, the optical cable is closer to the diversion pipeline of the petrochemical pipeline 6 due to the action of the pressing block 406, the clamping block 404 can be clamped by a tool by an operator, then the screw 403 is rotated through the clamping block 404, the screw 403 rotates to drive the fifth mounting plate 405 and the pressing block 406 to move forwards or backwards, the distance between the optical cable and the diversion pipeline of the petrochemical pipeline 6 is enabled to be more closely attached, the optical cable is further prevented from being distorted, and after the optical cable is wound by a circle, the end part of the optical cable is taken down from the clamping plate 401 and the mounting block 305 and is connected to another interface of the monitor 501 by the operator; the two moving units also drive the two fixed protection units to be close to each other when moving, so that the two fixed blocks 605 are in contact with each other, opposite sides of the two fixed blocks 605 are magnetic and are adsorbed together to form a fixed ring after being in contact with each other, after the optical cable is wound on the outer surface of the diversion pipeline of the petrochemical pipeline 6, the two fixed protection units are controlled to put down the fixed ring to press the optical cable at the joint of the main pipeline 6 and the diversion pipeline, and due to the arrangement of the arc-shaped grooves of the fixed blocks 605, the bending trend of the optical cable is attached to the arc trend at the joint of the main pipeline and the diversion pipeline, in order to enable the optical cable to be closely attached to the joint, a limiting strip 606 is arranged, and the limiting strip 606 has elasticity and can extrude the optical cable to be attached to the joint; thus, the monitor 501 can monitor the condition of the joint of the petrochemical pipeline 6 through the optical cable, detect the temperature and vibration of the joint and further determine whether the pipeline leaks; as shown in fig. 9, when the rear fixed protection unit works, the electric push rod 602 is controlled to start to drive the ninth mounting plate 603 and the two convex rods 604 to move backward, so that the two convex rods 604 are separated from the fixed block 605, and the fixed block 605 slides downward on the two polished rods 608 due to the gravity of the fixed block 605, thereby preventing the fixed block 605 from rotating when descending; when the monitoring position needs to be changed, the worker lifts the two fixing blocks 605 to reset, then pulls out the two ends of the optical cable from the interface on the monitor 501, screens the left part of the optical cable into the optical cable ring on the outer surface of the winding roller 505 to be fixed, controls the motor 502 to start to drive the transmission shaft 504 to drive the winding roller 505 to rotate to wind the optical cable, and then pulls the moving unit to separate by the worker.
