Description

Technical Field

[0001] The utility model relates to the relevant field of leakage monitoring, in particular to a distributed monitoring device for underground pipeline defects and damages. Background Art

[0002] As an important part of urban infrastructure, underground pipelines are responsible for transporting media such as water, gas, and oil, and are vital to ensuring the normal operation of cities and the lives of residents. However, since underground pipelines are in complex geological environments for a long time, they are easily affected by factors such as corrosion, wear, and external force damage, leading to safety accidents such as pipeline leakage and rupture. These accidents will not only cause waste of resources, but may also cause secondary disasters such as environmental pollution, fire, and explosion, posing a serious threat to people’s lives and property safety and social stability. Therefore, it is necessary to monitor underground pipelines for leakage, defects, and damage.

[0003] Existing monitoring devices, such as the Chinese utility model patent with patent number: CN202321786224.0, discloses "A pipeline leakage detection device". In this device, a sleeve is fixedly connected to the top of the upper fixed block, a baffle is slidably connected to the inner wall of the sleeve, a pull rod is fixedly connected to the inner wall of the baffle, a spring is provided on the outer wall of the pull rod, the top of the spring is fixedly connected to the bottom end of the baffle, the bottom end of the spring is fixedly connected to the bottom of the inner wall of the sleeve, the bottom end of the pull rod is fixedly connected to a connecting block, a lower fixed block is provided below the connecting block, and a fixing groove is provided at the bottom end of the lower fixed block; the position of the connecting block is adjusted by the pull rod, so that the connecting block is detached from the lower fixed block, thereby facilitating the installation and disassembly of the detection device, and the upper arc plate is provided with a gas collecting device to collect the gas, and then the gas pushes the piston to move and contact the device switch to trigger the alarm device, thereby reminding the staff that the pipeline is leaking.

[0004] Although the above device has certain advantages, it still has certain defects:

However, after being installed on the pipeline, the device may cause errors in the installation and sealing of the pipeline due to various factors, thereby reducing the working reliability of the detection device.

[0006] 2. The detection device of the device can sound an alarm after detecting a gas leak, and can filter the leaked gas to a certain extent to prevent a large amount of harmful gas from leaking to the outside. Although the device can filter the leaked gas to a certain extent in the above process, it does not perform emergency temporary sealing of the leaking pipeline, thereby fundamentally and temporarily preventing the gas from continuing to leak, reducing the property losses caused by the gas leak, and giving personnel more time to prepare for repairs and fault tolerance.
