Technical Field

[0001] The utility model relates to the field of pipeline safety detection equipment, in particular to an integrated pipeline optical acoustic vibration detector. Background Art

[0002] Installing cylindrical sensors or rectangular sensors on cylindrical pipes has the problem of a single contact surface, which means a large signal loss.

[0003] Traditionally, a sandwich structure of sensor unit + mounting base + pipe is used, but due to the different media in the propagation path, it will also cause large interface losses. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide an integrated pipeline optical acoustic vibration detector.

[0005] An integrated pipeline optical acoustic vibration detector comprises a detector housing, an optical vibration sensing unit and a restraining belt, wherein the detector housing is in an arc shape close to the outer wall of the pipeline and conforms to the curvature of the pipeline, the optical vibration sensing unit and the detector housing are designed as an integrated structure, the sensing surface of the detector housing is consistent with the shape of the outer wall of the pipeline, and the restraining belt is used to bind the integrated detector housing and optical vibration sensing unit to the pipeline.

[0006] Furthermore, the restraint belt is also provided with an optical tension sensor unit.

[0007] Furthermore, the restraining belt adopts a steel belt with self-binding.

[0008] The beneficial effects of the utility model compared with the prior art are:

[0009] 1. The optical vibration sensing unit of the utility model is installed on the outer wall of the pipeline and can effectively detect the vibration signal generated by pipeline leakage;

[0010] 2. The optical vibration sensor unit is integrated with the detector housing, and no additional mounting base or other auxiliary equipment is required. This can reduce the interface loss of different media in the signal propagation path and enhance the signal detection sensitivity. The shape of the optical vibration sensor unit is customized, and the shape of its sensing surface is consistent with the shape of the outer wall of the pipeline. After the integrated process is used, the sensor unit is in full contact with the pipeline, which greatly reduces the signal loss;

[0011] 3. The detector housing is connected with a self-binding steel belt, which can be conveniently and safely installed on the steel pipe and replaced during later maintenance;

[0012] 4. Make full use of the advantages of optical detection in long-distance detection, add optical tension sensor, not only detect the pipeline, but also monitor the connection reliability between the detector and the pipeline in real time, and enhance the effectiveness and reliability of the detector itself;

[0013] The utility model has reasonable structural design, is easy to install, enhances detection sensitivity, reduces signal loss, is convenient for installation and construction, and is easy for later maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
