Description

Technical Field

[0001] This utility model relates to the field of distributed optical fiber technology, and in particular to a mounting base for a distributed optical fiber sensor. Background Technology

[0002] Distributed fiber optic sensors employ unique distributed fiber optic sensing technology to measure or monitor the spatial distribution and time-varying information along the fiber optic transmission path. By arranging sensing fibers along the field, they can simultaneously acquire information on the spatial distribution and time-varying changes of the measured field, making them attractive for many industrial applications.

[0003] The principle of a distributed optical fiber sensing system is to simultaneously utilize optical fiber as both the sensing element and the signal transmission medium. By employing OTDR and OFDR technologies, it can detect changes in temperature and strain at different locations along the optical fiber, thus achieving truly distributed measurement.

[0004] Since the main body of the distributed fiber optic sensor is an optical cable structure, the optical cable is fixed by a wire-clamp structure mounting base. This type of mounting base is usually a fixed structure, and the optical cable can only go in and out in a straight line. When encountering special installation angles, it is difficult to adjust and use, which is not conducive to fixing the main body of the optical cable. In addition, different sizes of optical cables require different mounting bases, which increases the cost of optical cable laying.

[0005] To address the aforementioned issues, a mounting base for a distributed optical fiber sensor is proposed. Utility Model Content

[0006] The main purpose of this invention is to provide a mounting base for a distributed optical fiber sensor, which solves the problems mentioned in the background section.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] The mounting base includes a support plate;

[0010] The rotating mechanism includes a bearing that is rotatably mounted to the bearing plate, and a rotating support column is fixedly embedded in the inner ring of the bearing.

[0011] The threading mechanism includes a thread holder that is detachably mounted to the rotating support column, and the thread holder has a first thread holder hole and a second thread holder hole formed thereon.

[0012] Furthermore, the four corners of the support plate are provided with fixing screws for reinforcement.

[0013] Furthermore, a reserved hole with female thread is provided on the top inner wall of the rotating support column.

[0014] Furthermore, the wire clip holder is integrally formed from a bottom hexagonal base plate and a top set of six vertical plates, with the first wire clip hole penetrating through the six sets of vertical plates and the second wire clip hole penetrating through the hexagonal base plate.

[0015] Furthermore, a mounting screw is detachably located at the center of the hexagonal base plate, and the mounting screw is threadedly connected to the reserved hole.

[0016] Furthermore, the top of the first wire clip hole has an open structure, and the vertical plate is made of elastic plastic material.

[0017] The beneficial technical effects of this utility model are as follows:

[0018] This utility model designs an optical cable mounting base consisting of a mounting seat and a cable threading mechanism. It can be flexibly installed in the first and second line clamps according to the diameter of the distributed optical fiber sensor cable, achieving the purpose of multiple uses in one unit and reducing the laying cost of optical cable. At the same time, it can be used in combination at special bends by using adjacent first and second line clamps to fix the optical cable and ensure its stability, further improving the practicality of the mounting base.

[0025] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0026] like Figures 1-4 As shown, this embodiment provides a mounting base for a distributed optical fiber sensor, including a mounting base 1. The mounting base 1 has a rotating mechanism 3 inside, and a wire threading mechanism 2 is provided on the top of the rotating mechanism 3. The mounting base 1 includes a support plate 101. The rotating mechanism 3 includes a bearing 302 that is rotatably mounted to the support plate 101 and a rotating support column 301 is fixedly embedded in the inner ring of the bearing 302. The wire threading mechanism 2 includes a wire clip seat 201 that is detachably mounted to the rotating support column 301. The wire clip seat 201 has a first wire clip hole 202 and a second wire clip hole 203 formed on it.

[0027] In the above structure, the bearing 302 can support the top threading mechanism 2 to rotate flexibly, so as to realize the routing of wires at different angles and directions.

[0028] The four corners of the bearing plate 101 are provided with fixing screws 102 for reinforcement. The bearing plate 101 is made of metal and can serve as a grounding device to prevent the optical cable from being affected by the ground.

[0029] The top inner wall of the rotating support column 301 is provided with a reserved hole 301a with female thread. The structure of the reserved hole 301a and the mounting screw 204 allows the wire threading mechanism 2 to be flexibly separated from the mounting base 1, which is convenient for timely replacement and maintenance when damaged, and saves the work of disassembling the mounting base 1.

[0030] The cable holder 201 is integrally formed from a hexagonal base plate at the bottom and six sets of vertical plates at the top. The first cable holder hole 202 passes through the six sets of vertical plates, and the second cable holder hole 203 passes through the hexagonal base plate. The diameter of the first cable holder hole 202 is 10-20mm, and the diameter of the second cable holder hole 203 is 5-10mm. Both are hexagonally distributed, allowing for straight or bent cable threading. Since optical cables cannot be bent or stretched excessively during installation, the first cable holder hole 202 and the second cable holder hole 203 need to be bent at a set angle when installing the optical cable of the distributed optical fiber sensor to avoid affecting the signal transmission quality of the optical fiber inside the cable.

[0031] A mounting screw 204 is detachable at the center of the hexagonal base plate, and the mounting screw 204 is threaded into the reserved hole 301a.

[0032] The top of the first wire clip 202 has an open structure, and the vertical plate is made of elastic plastic. This design is to facilitate the direct insertion of thicker optical cables into the first wire clip 202 through the open structure, making operation easier.

[0033] The working principle of this device is as follows: During use, the device selects either the first wire clamp 202 or the second wire clamp 203 for fixing, depending on the diameter of the optical cable on the distributed fiber optic sensor. The first wire clamp 202 allows the optical cable to be directly pressed into the hole from the top for locking, which is convenient and quick. The second wire clamp 203 allows the cable to be inserted from one end and exited from the other end via a threading method for limiting its movement.

[0034] When installed in a straight line, the optical cable can enter and exit directly from the corresponding first line clip 202 or second line clip 203. When installed at a bend, the optical cable can enter from the first line clip 202 or second line clip 203 and exit from the adjacent first line clip 202 or second line clip to achieve bend fixation.

[0035] The above structure greatly improves the flexibility of the mounting base 1, which is conducive to the on-site installation and laying of distributed optical fiber sensors of different diameters, reduces the number of mounting bases 1 used, and thus reduces the installation cost of distributed optical fiber sensors.

[0036] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0037] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
