[0031] It also includes a fixing structure, which is disposed between the outer pipe 12 and the mounting frame 15 and is used to fix the outer pipe 12 and the mounting frame 15;

[0032] The positioning structure is arranged at the upper end of the mounting frame 15 and is used for installing the mounting block 24 and the pressing block 32 .

[0033] In this embodiment, the outer pipe 12 is first fixed to the mounting frame 15 by a fixing structure, and then the mounting block 24 and the pressing block 32 are installed by a positioning structure. The pipeline pressure data collected by the pipeline leakage monitor 33 arranged at the lower end of the pressing block 32 is transmitted to the external device through the wireless module 34, thereby achieving the effect of monitoring the petrochemical pipeline.

[0034] In one embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the fixing structure includes a screw 19 and a fixed arc block 20. A group of threaded holes are opened at the upper end of the mounting frame 15. The screw 19 is threadedly installed on the threaded holes opened in the mounting frame 15. The fixed arc block 20 is located at the upper end of the outer pipe 12. The bottom end of the screw 19 is rotatably connected to the fixed arc block 20. A buffer assembly is provided at the connection between the screw 19 and the fixed arc block 20.

[0035] By rotating the screw 19, the screw 19 and the mounting frame 15 move relative to each other, and the screw 19 drives the fixed arc block 20 to move, so that the fixed arc block 20 is close to the outer pipe 12, so that the fixed arc block 20 abuts against the outer wall of the outer pipe 12, and then the outer pipe 12 and the mounting frame 15 are fixed.

[0036] In one embodiment, Figure 5As shown, the buffer assembly includes a rotating block 23 and a spring groove 21. The fixed arc block 20 is provided with a spring groove 21. One end of the screw 19 located inside the spring groove 21 is rotatably connected to the rotating block 23. The outer wall of the rotating block 23 is slidably connected to the inner wall of the spring groove 21. A damping spring 22 is installed inside the spring groove 21.

[0037] When the fixed arc block 20 abuts against the outer wall of the outer pipe 12, the screw 19 is rotated, and the rotating block 23 compresses the damping spring 22. The damping spring 22 makes the fixed arc block 20 not easily squeeze and damage the fire protection pipe while firmly fixing the petrochemical pipe.

[0038] In one embodiment, Figure 2 , Figure 4 and Figure 6 As shown, the positioning structure includes a positioning groove 17, a positioning groove 17 is provided at the upper end of the mounting frame 15, the positioning groove 17 is slidably connected to the mounting block 24, disassembly openings 31 are symmetrically provided on both sides of the mounting block 24, and a locking assembly is provided on the top of the positioning groove 17 and one side of the mounting block 24.

[0039] The mounting block 24 is slidably installed inside the positioning groove 17, and the staff fixes the mounting block 24 and the mounting frame 15 through the locking assembly, so that the pipeline leak prevention monitor 33 at the lower end of the pressing block 32 can monitor the petrochemical pipeline. When the mounting block 24 needs to be disassembled, the staff disassembles the mounting block 24 and the mounting frame 15 through the disassembly opening 31.

[0040] In one embodiment, Figure 4 and Figure 7 As shown, the locking assembly includes a lock hole 18, a rebound groove 25 and a movable groove 26, the lock hole 18 is opened at the inner end of the positioning groove 17, the rebound groove 25 and the movable groove 26 are opened at the top inside the mounting block 24, the inside of the rebound groove 25 is connected with the inside of the movable groove 26, and a pull rod 27 is slidably installed inside the rebound groove 25 and the movable groove 26, the outer wall of the pull rod 27 is fixedly connected to a limit block 28, the limit block 28 is slidably connected to the rebound groove 25, a spring 30 is sleeved on the outside of the pull rod 27, one end of the spring 30 is fixedly connected to the limit block 28, and the end of the pull rod 27 close to the movable groove 26 is fixedly connected to a lock block 29 matching the lock hole 18.

[0041] By pulling the pull rod 27, the limit block 28 compresses the spring 30, and the locking block 29 enters the movable groove 26. The mounting block 24 is slidably installed in the positioning groove 17. Then the pull rod 27 is released, and the pull rod 27 and the locking block 29 are reset under the rebound action of the spring 30. The locking block 29 enters the locking hole 18, thereby fixing the mounting block 24 and the positioning groove 17.

[0042] In one embodiment, Figure 7 As shown, the other end of the pull rod 27 extends to the rebound groove 25 to be fixedly connected to the pull ring.

[0043] By extending the pull ring at the other end of the pull rod 27 to the rebound groove 25 for fixing and connecting, it is convenient for the staff to pull the pull rod 27 through the pull ring, thereby facilitating the locking assembly to fix the mounting block 24 and the positioning groove 17.

[0044] Example 2

[0045] In one embodiment, Figure 4 As shown, a silicone cushion is fixedly mounted on the upper end of the positioning ring frame 16 .

[0046] The silicone cushion can avoid direct contact between the positioning ring frame and the outer pipe 12, reduce surface damage caused by friction or collision, and protect the surfaces of both sides.

[0047] In one embodiment, Figure 4 As shown, the surface of the silicone pad is provided with anti-slip patterns.

[0048] By providing anti-slip grooves on the surface of the silicone pad, the friction coefficient of the silicone pad surface is increased, thereby increasing the friction between the silicone pad and the outer pipe 12, thereby avoiding the deviation of the mounting frame 15 and the outer pipe 12, thereby ensuring the accuracy of the monitoring results.

[0049] The above embodiment discloses a petrochemical pipeline with a leak-proof monitoring function, wherein, first, the staff installs the mounting frame 15 on the outside of the outer pipe 12, and by rotating the screw 19, the screw 19 and the mounting frame 15 move relative to each other, and the screw 19 drives the fixed arc block 20 to move, so that the fixed arc block 20 is close to the outer pipe 12, so that the fixed arc block 20 abuts against the outer wall of the outer pipe 12, and then the outer pipe 12 is fixed to the mounting frame 15, and by pulling the pull rod 27, the limit block 28 makes The spring 30 is compressed, the locking block 29 enters the movable groove 26, the mounting block 24 is slidably installed in the positioning groove 17, and then the pull rod 27 is released. Under the rebound action of the spring 30, the pull rod 27 and the locking block 29 are reset, and the locking block 29 enters the lock hole 18, thereby fixing the mounting block 24 and the positioning groove 17. The pipeline pressure data collected by the pipeline leakage monitor 33 set at the lower end of the pressure block 32 is transmitted to the external device through the wireless module 34, thereby achieving the effect of monitoring the petrochemical pipeline.
