Municipal water supply and drainage pipeline laying explosion-proof device and protection method

Abstract

The invention discloses a municipal water supply and drainage pipeline laying explosion-proof device and a protection method. The municipal water supply and drainage pipeline laying explosion-proof device comprises two explosion-proof pipelines of which the end parts are fixedly connected with each other, the explosion-proof pipelines are welded and sleeved with fixing sleeves, and the two fixing sleeves are provided with the same group of protection mechanisms; and the protection mechanism comprises an inner sleeve which is movably arranged on the two fixing sleeves in a sealed and sleeving mode, a plurality of L-shaped fixing blocks are annularly welded and fixed to the two sides of the inner sleeve, the L-shaped fixing blocks are fixed to the outer sides of the corresponding fixing sleeves in a threaded mode, and the inner sleeve is sleeved with an outer protection pipe. The municipal water supply and drainage pipeline laying explosion-proof device is reasonable in design, facilitates multi-directional buffer protection of the joint of the two anti-explosion pipelines, relieves and reduces collision force generated by mistaken collision, improves the protection effect of the joint, reduces the risk of burst leakage caused by mistaken collision of the joint, facilitates automatic sound-light alarm reminding and temporary plugging when leakage occurs at the joint, meets the use requirements, and facilitates application.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage pipelines, in particular to an explosion-proof device and protection method for laying municipal water supply and drainage pipelines. Background technique [0002] At present, the water supply and drainage pipeline project is a pipeline system project that transports and distributes industrial water supply and domestic drinking water, and collects, transports and discharges industrial wastewater, domestic sewage and rainwater. Long-distance water supply and drainage pipelines are mostly formed by welding multiple explosion-proof pipes. This kind of jointless pipe formed by butt welding is also called continuous pipe; [0003] Most of the long-distance water supply and drainage pipes will be fixed in the soil on the ground, but some of them will be in an overhead state due to environmental geological factors; The connection of the explosion-proof pipe is prone to cracking and lea...

AI Technical Summary

Problems solved by technology

[0003] Most of the long-distance water supply and drainage pipes will be fixed in the soil on the ground, but some of them will be in an overhead state due to environmental geological factors; The connection of the explosion-proof pipe is prone to cracking and leakage due to long-term use, oxidation or accidental contact. Therefore, the explosion-proof protection of the exposed part of the connection is an important prerequisite for long-term stable use.

[0004] Most of the joints of existing water supply and drainage pipes do not have explosion-proof buffer protection and the function of automatically alarming and reminding personnel in case of leakage, so that the risk of bursting and leaking at the joints due to collisions at overhead exposed parts is high. To meet the needs of use, we propose a kind of explosion-proof device and protection method for laying municipal water supply and drainage pipelines
