Technical Field

[0002] Most urban gas pipelines are buried underground. According to accident statistics, the main causes of pipeline leakage are third-party damage and corrosion. Third-party damage is often manifested as municipal construction digging or breaking the pipeline, which leaks quickly and in large quantities. Corrosion is manifested as the pipe wall being eroded and gradually thinning, with leakage points.

Through the setting of the warning device, it is possible to give an early warning before a serious leak occurs in the gas pipeline, thereby preventing a serious leakage disaster.
[0004] The existing gas pipeline monitoring and early warning devices are generally installed at the pipeline welding points to monitor the air pressure at the pipeline welds. This method requires the hose to be inserted and installed on the outside of the pipeline weld to wrap the pipeline weld, which is very inconvenient to install. In addition, the existing gas pipeline monitoring and early warning devices only monitor whether the pipeline is leaking by air pressure, and the reliability is not high. Utility Model Content

[0027] The limiting tube 1 is a half-tubular structure, and the limiting tube 1 is connected in a mirror-symmetrical manner with the axis of the gas pipeline as the reference. The front and rear sides of the limiting tube 1 are provided with conical structures in a mirror-symmetrical manner with the center of the limiting tube 1 as the reference. The protective shell 11 is movably connected to the limiting tube 1 through the fixing bolts 12.
[0028] The connecting block 13 is installed on the upper and lower sides of the limiting tube 1 in a mirror-symmetrical manner with the center of the limiting tube 1 as the reference, and the limiting block 14 is installed on the upper and lower ends of the front and rear sides of the limiting tube 1 in a front-back and top-bottom symmetrical manner with the center of the limiting tube 1 as the reference.
[0029] The fastening bolt 15 penetrates the connecting block 13 and the limiting block 14 outside the left limiting tube 1 from left to right and is connected with the connecting block 13 and the limiting block 14 outside the right limiting tube 1 .
[0030] The vibration sensor 16 is fixedly connected to the limiting tube 1 . The vibration sensor 16 is symmetrically installed on the front and rear sides of the limiting tube 1 with the center of the limiting tube 1 as the reference. The inner wall of the connecting ring 17 is consistent in size with the inner walls of the front and rear ends of the rubber tube 18 .
[0031] The air pressure monitor 19 passes through the limit tube 1 and the rubber tube 18 and is connected to the inner cavity of the rubber tube 18 . The air pressure monitor 19 and the logic controller 110 are electrically connected.
[0032] The antenna 112 extends from the inside of the protective shell 11 through the protective shell 11 to the front side of the protective shell 11 .
[0033] Specifically, the limit tube 1 can apply pressure to the rubber tube 18 so that the rubber tube 18 can be close to the gas pipeline, the protective shell 11 can protect the logic controller 110, the fixing bolt 12 can limit the position of the protective shell 11, the connecting block 13 and the limit block 14 can facilitate the installation of the fastening bolt 15, and the fastening bolt 15 can increase the relative pressure between the limit tube 1, the vibration sensor 16 model is TX9W233, the vibration sensor 16 can monitor the pipeline vibration, and the connecting ring 17 can facilitate the vibration sensor 16 and the pipeline. The rubber tube 18 can improve the air tightness of the device. The model of the air pressure monitor 19 is JC-1000D-HSM. The air pressure monitor 19 can monitor the internal air pressure of the rubber tube 18. The model of the logic controller 110 is TM200C24R. The model of the signal transceiver 111 is NAX3012. The logic controller 110 can perform logical operations on the detection data of the air pressure monitor 19 and the vibration sensor 16 and control the signal transceiver 111 to send an alarm signal according to the operation results. The antenna 112 can facilitate signal transmission and reception.
[0034] When in use, the limit tube 1 is a half-tubular structure, and the limit tube 1 is connected symmetrically on the left and right sides with the axis of the gas pipeline as the reference. The limit tubes 1 are connected by connecting blocks 13, limit blocks 14, and fastening bolts 15. When installing, the welding point of the gas pipeline can be wrapped from the left and right sides of the gas pipeline. Then, the relative pressure between the limit tubes 1 is adjusted by rotating the fastening bolts 15, so that the limit tube 1 applies pressure to the rubber tube 18, and the rubber tube 18 is squeezed through the gas pipeline and the limit tube 1, so that the rubber tube 18 wraps the gas pipeline. This method can facilitate the installation of the device, reduce the installation steps, and shorten the installation process. After the installation is completed, a cavity is formed between the rubber tube 18 and the gas pipeline, and the air pressure monitor 19 can monitor the air pressure in the cavity. When there is no leakage at the welding point of the gas pipeline, the air pressure inside the cavity is stable. When there is a leakage at the welding point of the gas pipeline, the gas enters the cavity between the rubber tube 18 and the gas pipeline, causing the air pressure inside the cavity to rise. The monitoring data of the air pressure monitor 19 increases. Since the logic controller 110 performs logic operations on the monitoring data of the air pressure monitor 19, when the monitoring data of the air pressure monitor 19 exceeds the threshold value, the logic controller 110 controls the signal transceiver 111 to send an alarm signal through the antenna 112. The end of the vibration sensor 16 contacts the gas pipeline through the connecting ring 17. When the gas pipeline leaks, the gas will produce friction with the cracks in the pipeline, causing the pipeline to vibrate. The vibration can be transmitted to the vibration sensor 16 through the gas pipeline and the connecting ring 17. The vibration sensor 16 can monitor the vibration of the pipeline and transmit the monitoring data to the logic controller 110. The logic controller 110 can perform logic operations on the monitoring data and control the signal transceiver 111 to send an alarm signal through the antenna 112 according to the operation results. This method can monitor the vibration state of the pipeline while monitoring the air pressure, and can improve the reliability of the device alarm.
