Optical fiber sensor mounting structure of natural gas pipeline leakage optical fiber monitoring system

Abstract

The invention discloses an optical fiber sensor mounting structure of a natural gas pipeline leakage optical fiber monitoring system. The structure comprises supporting frames which are arranged on the two sides of the optical fiber sensor, the two supporting frames are connected on the side face of the lower portion of the optical fiber sensor in a clamped mode, the two ends of the supporting frames are correspondingly provided with first rack rods, first inserting grooves are formed in the two ends of the supporting frames, and the first inserting grooves are located on one sides of the first rack rods; gears are rotationally connected in the first inserting grooves, one ends of the gear are connected with rotating rods, and rotating openings communicating with the first inserting grooves are formed in the upper portion of the supporting frames; and one ends of the rotating rods penetrate through the rotating openings, and one end, away from one of the supporting frames, of the firstrack rod is inserted into the first inserting groove of the other supporting frame. According to the structure, triple locking and clamping-connecting effects are achieved, one layer is connected toanother layer in a clamped mode, so that the optical fiber sensor mounting structure of the natural gas pipeline leakage optical fiber monitoring system can be more stable, and the invention providesthe optical fiber sensor mounting structure of the natural gas pipeline leakage optical fiber monitoring system.

Description

technical field [0001] The invention relates to the technical field of an optical fiber sensor installation structure, in particular to an optical fiber sensor installation structure of a natural gas pipeline leakage optical fiber monitoring system. Background technique [0002] At present, the total length of pipelines built in the world has reached 2.5 million kilometers, which has surpassed the total mileage of railways and has become the main mode of energy transportation in the world. Oil transportation in developed countries and oil-producing regions in the Middle East has all realized pipelines. Throughout the various pipeline leakage monitoring technologies at home and abroad, the current commonly used negative pressure wave method, flow balance method, pressure slope and other oil pipeline leakage detection technologies cannot effectively solve the problem of gas pipeline leakage detection, especially for Identification and positioning of tiny leaks; and the current...

Problems solved by technology

Throughout the various pipeline leakage monitoring technologies at home and abroad, the current commonly used negative pressure wave method, flow balance method, pressure slope and other oil pipeline leakage detection technologies cannot effectively solve the problem of gas pipeline leakage detection, especially for Identification and positioning of tiny leaks; and the current installation structure of optical fiber sensors cannot have multiple snap-in locking effects, resulting in unstable installation and connection of optical fiber sensors, which in turn affects the user's use effect

[0003] Therefore, it is urgent to design an optical fiber sensor installation structure for a natural gas pipeline leakage optical fiber monitoring system to solve the problem of insufficient stability of the installation connection and single snap-in locking in the prior art
