Problems solved by technology

However, for the detection of the internal pressure of oil and gas pipelines, ordinary pressure sensors are mostly used in the prior art, and the reliability is poor. Oil and gas are in a closed oil and gas pipeline, and the accuracy is easily reduced due to the interference of oil pollution, thereby affecting the detection effect.

Embodiment 1

[0044] like Figure 1 to Figure 6 As shown, the optical fiber detection device for oil and gas pipeline leakage with high sensitivity in this embodiment includes a detection module 1000. The detection module 1000 is installed on the installation ring 2000 and penetrates into the installation ring 2000. Flanges 2100 are provided on both sides; it also includes a transceiver module 3000, which is connected to the detection module 1000 through an optical fiber; the detection module 1000 includes a mounting seat 1100, and the mounting seat 1100 is provided with a The installation ring 2000 and the detection chamber 1101 of the detection module 1000 are slidably connected with a pressure rod 1200 in the detection cavity 1101 perpendicular to the inner wall of the installation ring 2000 , and the bottom of the pressure rod 1200 is elastically connected to the detection chamber through a spring 1250 At the bottom of the cavity 1101, the side opening of the detection cavity 1101 facin...

Embodiment 2

[0064] like Figure 7 and Figure 8 As shown, the optical fiber detection device for oil and gas pipeline leakage with high sensitivity in this embodiment is different from the technical solution in the above-mentioned embodiment in that the waist-shaped through holes 1211 on the position feature plate 1210 are vertically arranged with several Each of the waist-shaped through holes 1211 is provided with electronically controlled glass 1213, and the electronically controlled glass 1213 is electrically connected to the pulse generator (not shown in the figure) of the transceiver module 3000. The device sends different pulse signals to the different electric control glass 1213, so that the electric control glass 1213 can be turned on and off at different frequencies.

[0065] Since the transparency of the electronically controlled glass 1213 decreases after power-on, the opposite optical fiber 1231 cannot transmit the optical signal through the electronically controlled glass 12...

Description

technical field [0001] The invention relates to the field of detection, and more particularly, to an optical fiber detection device for oil and gas pipeline leakage with high sensitivity. Background technique [0002] With the development of the city, the normal operation of the city is inseparable from the continuous supply of oil and natural gas, and the oil and gas pipeline is the most important thing in the transportation of oil and gas. [0003] Because the oil and gas pipelines are usually far away and the environment of the laying site is complex, in order to ensure the normal operation of the oil and gas pipelines, it is necessary to monitor the transportation conditions of the oil and gas pipelines in real time, so as to detect the leakage of the oil and gas pipelines as soon as possible and carry out emergency treatment as soon as possible, so as to ensure the normal operation of the oil and gas pipelines. To ensure the normal supply of oil and gas, the leakage mon...
