Novel prefabricated heat preservation pipe and seepage detection alarm system used for same

Abstract

The invention provides a novel prefabricated heat preservation pipe and a seepage detection alarm system used for the same. The seepage detection alarm system is arranged in a heat preservation layer adjacent to the heat preservation pipe and comprises multiple sensor line pipelines, multiple feedback line pipelines and a control center, wherein the multiple sensor line pipelines are distributed at multiple positions of the steel pipe, an inner sleeve corresponding to each feedback line pipeline is located in one sensor line pipeline, the sensor line pipelines are connected with the feedback line pipelines in a one-to-one corresponding mode, and each feedback line pipeline is in communication with the control center. The seepage detection alarm system can acquire heat support data of all positions of the steel pipe, feed the data back to the control center, provide the data to an administrator for checking, analysis and positioning of the steel pipe position where seepage occurs, hidden dangers are prevented before dangers emerge, and safety reliability is improved.

Description

technical field [0001] The invention relates to the technical field of heat pipes, in particular to a novel prefabricated heat preservation pipe and a leak detection and alarm system for it. Background technique [0002] The prefabricated insulation pipe is made of polyurethane foam as the insulation material, and high-density polyethylene is used as the shell of the insulation pipe. Because this kind of insulation pipe has good water resistance, it can be used in areas with high groundwater level and moist soil. Existing two kinds of novel prefabricated insulation pipes: one is the prefabricated insulation pipe in the form of polyethylene for the insulation structure, and the other is the prefabricated insulation pipe in the form of a pipe in a pipe. At present, these two forms of prefabricated insulation pipes have been mass-produced and widely used in urban heating pipe networks and industrial and mining enterprises. In recent years, direct-buried thermal pipelines with...

AI Technical Summary

Problems solved by technology

[0004] First, once the water leaks after the backfill of the pipeline is laid, it is difficult to find the leak point, and the degree of maintenance is quite difficult;

[0005] Second, the service life is short, generally 30 years

[0006] After the direct-buried polyurethane insulation pipe is put into use, due to its structural characteristics and high cost, any small damage (such as the inside of the steel pipe and the outside of the HDPE outer casing) will lead to expensive maintenance costs, thereby reducing revenue and pipe life
