A telescopic pipeline flow generator

Abstract

The invention relates to a telescopic pipeline flow generator, which belongs to the technical field of new energy and pipeline monitoring. The inner wall of the pipeline is equipped with a shell through the radial plate, and the end of the side wall of the shell is equipped with an end cover; the left and right sides of the vertical plate of the support are provided with left and right pins, and the right sides of the upper and lower ends are provided with horizontal plates with inclined mounting surfaces; The left pin protrudes through the bottom wall of the shell, and a blunt body is installed at the end of the left pin; a support spring and a buffer spring are respectively set between the bottom wall of the upper shell of the left pin, the blunt body and the vertical plate of the bracket; From left to right, there are left spring, exciter, frequency modulation block and right spring in turn. The exciter is connected to the frequency modulation block. The right end of the right spring is against the stopper at the end of the right pin; A moving cam composed of a bottom surface, a slope and a top surface is provided in the axial direction; one end of the piezoelectric vibrator is installed on the mounting surface of the bracket, and the flange of the piezoelectric vibrator substrate is in contact with the midpoint of the cam slope when it is not working, and the assembly is pre-bent and deformed The amount is half of its allowable value, and the allowable deformation of the piezoelectric vibrator is greater than the cam lift.

Description

technical field [0001] The invention belongs to the technical field of new energy and oil and gas pipeline monitoring systems, and in particular relates to a telescopic pipeline flow generator. Background technique [0002] During the operation of oil and gas pipelines, oil and gas pipeline leakage incidents occur frequently due to natural corrosion, force majeure of nature, especially man-made theft, which not only caused huge economic losses, but also caused serious pollution to the surrounding natural environment. In the past, it was maintained by manual inspection methods, but because the pipeline laying distance is long, and it is often in an inaccessible or inconvenient place, it is difficult to detect leakage in time and repair it in time, so people have proposed various types of pipeline leakage monitoring or anti-theft systems. , some technologies are relatively mature; but the power supply problem of the oil and gas pipeline monitoring system has not been well reso...

Problems solved by technology

[0002] During the operation of oil and gas pipelines, due to natural corrosion, natural force majeure, especially man-made theft, oil and gas pipeline leakage incidents occur from time to time, which not only caused huge economic losses, but also caused serious pollution to the surrounding natural environment.

In the past, it was maintained by manual inspection methods, but because the pipeline laying distance is long, and it is often in an inaccessible or inconvenient place, it is difficult to detect leakage in time and repair it in time, so people have proposed various types of pipeline leakage monitoring or anti-theft systems. , some technologies are relatively mature; but the power supply problem of the oil and gas pipeline monitoring system has not been well resolved: the cost of laying cables is high and it is easy to be cut off by criminals, which will affect the normal operation of the monitoring system. Frequent replacement, once the battery is low and not replaced in time, the remote transmission of monitoring information cannot be completed
