Problems solved by technology

[0006] (2) Lack of accident warning function, the alarm signal can be sent only after the accident occurs and the tube bursts and leaks
[0007] (3) Complex system, high cost and low reliability
The above technology involves a large number of switching devices for industrial production, the detection and auxiliary systems are complex, and there are many wirings. For buried pipelines, the complexity of the system not only increases the overall cost, but also reduces the reliability of the system.

Embodiment 1

[0028] Such as figure 1 , 2 The shown safety monitoring device for a plastic pipeline includes a support ring 4, a plurality of spring sheets 3 placed in the support ring 4, a switch device 5 placed on the spring sheet 3, the support ring 4, the spring sheet 3, and the switch The device 5 is installed in the protective shell, and the spring sheet is squeezed and deformed to cause the switching device to be turned on, and a logical OR relationship is formed among multiple switching devices. Specifically, such as Figure 4 As shown, multiple switching devices are connected in parallel, and when one switching device is turned on, the entire monitoring device is triggered. The monitoring device is installed as figure 1 As shown, when in use, it is buried and underground together with the pipeline, the support ring 4 is sleeved outside the pipeline 1, the spring sheet 3 is placed between the support ring 4 and the pipeline 1, and the switch device 5 is fixed on the spring sheet. Whe...

Embodiment 2

[0032] Based on the structure of the above embodiment, this embodiment discloses a preferred implementation. The monitoring device of this scheme realizes the monitoring of local deformation of the pipeline. The protective shell mainly isolates the soil. In order to avoid the influence of the protective shell on the reliability of monitoring, such as figure 2 As shown, the protective shell includes an annular shell 6 and elastic corrugated plates 7 placed on both sides of the shell. Similarly, in order to facilitate installation, the shell 6, the elastic corrugated plates and the support ring 4 have the same structure, and all adopt a spliced ​​annular structure. . The elastic corrugated board and shells can be connected by existing methods such as bonding. During installation, the shell 6 is sleeved outside the pipe and the support ring 4, which is concentric with the support ring 4 and the pipe. The shell adopts a rigid structure to effectively isolate the soil. The elastic ...

Embodiment 3

[0034] Based on the above-mentioned plastic pipeline safety monitoring device, this embodiment discloses a plastic pipeline safety monitoring system. Specifically, the system includes a plurality of monitoring devices in Embodiment 1, a first-level node that realizes the signal collection of the switching device of the monitoring device, and a pair of multiple A second-level node that collects signals from a first-level node; the first-level node and the second-level node have unique addresses respectively. Multiple monitoring devices monitor the pipeline within a certain range. They communicate with a first-level node, and multiple first-level nodes communicate with a second-level node. The second-level nodes realize remote transmission of monitoring signals. The system adopts two-level transmission mode, which can simplify wiring and reduce costs. Each first-level node and second-level node has a unique address. When the switching device of a monitoring device is triggered, t...

Abstract

The invention discloses a monitoring device and system for the security of a plastic pipeline. The monitoring device comprises a supporting ring, a plurality of spring pieces arranged in the supporting ring, switching devices which are arranged on the spring pieces and can achieve switching conduction when the spring pieces are deformed, and a protection casing coating the supporting ring, whereinthe switching devices constitute a relation of "logic or". According to the monitoring device and system, the supporting ring is adopted for protecting and fixing the switching devices, when the interior of the pipeline cracks, there is enough strength to restrict cracking of the plastic pipeline, and the effect of inhibiting cracking is achieved. The switching devices are distributed around thepipeline, and constitute a relation of "logic or", when accidents such as third-party damage, geological sedimentation damage or expansion and deformation take place, at least one switching device istriggered, then it is judged that an accident takes place, and early warning is achieved before the pipeline gets damaged.

Description

Technical field [0001] The invention relates to the field of pipeline monitoring devices, and more specifically to a plastic pipeline safety monitoring device and system. Background technique [0002] Pipes are the most economical and environmentally friendly fluid transportation equipment. With the development of polymer material technology and processing industry, plastic pipes are used in the process industry, urban infrastructure and construction fields due to their advantages of easy processing and molding, corrosion resistance, good impact resistance, environmental protection, convenient construction, and good comprehensive energy-saving performance. It has gradually replaced metal pipes, and has been widely used in the transportation of medium and low pressure fluids such as gas, domestic water, sewage, and corrosive chemical media. [0003] At present, the total mileage of plastic pipelines in my country has exceeded 1 million kilometers, most of which are buried undergrou...
