[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] Example: Figure 1 , 2 As shown in Figure 3, the device for measuring pipeline accompanying optical cables of this embodiment includes two semicircular magnetic cores 1 and cables 2. The two magnetic cores 1 are respectively wrapped with semicircular insulating shells 3, and the two end portions of the magnetic cores 1 are respectively exposed to the two ends of the insulating shells 3. The two ends of the two magnetic cores 1 are adsorbed one by one. The cable 2 is connected to one of the insulating shells 3, and the two wires inside it are respectively connected to the two ends of one of the magnetic cores 1. The two insulating shells 3 form an optical cable throughhole.

[0026] During the manufacturing process of the device for measuring the pipeline accompanying optical cable of this embodiment, a completely closed magnetic ring is cut into two halves to form two semi-circular magnetic cores 1. At the same time, in order to ensure that the two halves of the magnetic core are aligned and matched for easy installation, two semi-circular insulating shells 3 (usually a hard plastic shell) are made, and the two halves of the magnetic core 1 are respectively fixed in the two insulating shells 3. At the same time, the N and S levels at both ends of one of the magnetic cores 1 are respectively led out with a 1.5-square cable 2 for connecting the measuring instrument; an induction coil is formed, which is buried underground when in use, and each insulating shell 3 of the chain is enclosed outside the accompanying optical cable and fixed. In actual applications, when it is not possible to directly connect to the accompanying optical cable of the pipeline to be measured, a coupling clamp can be used for coupling detection. The device for measuring the pipeline accompanying optical cable of this embodiment is a clamp induction coil that plays a coupling role in the detection of the pipeline accompanying optical cable. An external transmitter is used to transmit a fixed frequency signal to the clamp induction coil, and the induction current is used to strengthen the core construction current signal of the pipeline accompanying optical cable, thereby locating the position and buried depth of the pipeline accompanying optical cable. The overall design is relatively simple and reasonable. By making a buried measuring device, the cost of measuring the pipeline accompanying optical cable is reduced, the measurement and positioning efficiency is improved, and the safety of the pipeline accompanying optical cable is effectively protected.

[0027] As a preferred real-time manner, one end of the two insulating shells 3 is hinged.

[0028] In the above embodiment, one end of the two insulating shells 3 is hinged, so that the two insulating shells 3 can be opened and closed, which is convenient for use.

[0029] In this embodiment, one end of the two insulating shells 3 is generally hinged by a hinge.

[0030] As a preferred embodiment, the other ends of the two insulating shells 3 are separated after being locked or unlocked by a locking structure 4 .

[0031] In the above embodiment, after the two insulating shells 3 are docked and the two ends of the internal magnetic core 1 are adsorbed, the other ends of the two insulating shells 3 are locked and fixed by the locking structure 4, so that the two halves of the magnetic core 1 are better stabilized and will not be easily separated.

[0032] As a preferred embodiment, a connecting portion 31 is respectively provided on the outer side of the other end of the two insulating shells 3, and the locking structure 4 includes a bolt. The two connecting portions 31 are fitted together and connected by a bolt passing through the two.

[0033] In the above embodiment, after the two insulating shells 3 are flipped over to butt against each other at both ends, the connecting parts 31 at the other ends of the two insulating shells 3 fit together, and then the two connecting parts 31 are locked and fixed by bolts passing through the two connecting parts 31 and nuts matching the bolts, thereby fixing the insulating shells 3, that is, achieving a stable adsorption connection between the two magnetic cores 1.

[0034] As a preferred embodiment, an annular sealing gasket 32 ​​is sandwiched between the two ends of the two insulating shells 3 , and the two end portions of any one or both of the insulating shells 3 are respectively provided with sealing ring grooves adapted to the sealing gasket 32 ​​.

[0035] In the above embodiment, after the two ends of the two insulating shells 3 are butted against each other, the sealing gasket 32 ​​is mounted on the two ends of the insulating shell 3 and is arranged outside the end of the magnetic core 1 to seal the two ends of the insulating shell 3. The waterproof performance is good, ensuring the effective overlap of the two magnetic cores 1 to achieve the optimal magnetic circuit.

[0036] As a preferred embodiment, the gap between the magnetic core 1 and the insulating shell 3 is filled with colloid, and one side of the two insulating shells 3 is respectively provided with a concave packaging groove 33, and the packaging groove 33 is provided with a filling hole connected to the gap.

[0037] In the above embodiment, during the production process, the gap is alternately poured through the packaging groove 33, so that the magnetic core 1 and the insulating shell 3 are firmly connected, and at the same time, the gap is sealed and waterproofed.

[0038] As a preferred embodiment, a positioning assembly 5 for positioning the optical cable is provided on the other side of the two insulating housings 3 .

[0039] In the above embodiment, during use, after the accompanying optical cable passes through the optical cable hole, the optical cable is positioned and maintained in the optical cable hole by the positioning component 5, thereby playing a role in stable detection of the optical cable.

[0040] As a preferred embodiment, the positioning assembly 5 includes at least four groups of positioning bolts 51, and the other ends of the two insulating shells 3 are respectively provided with at least two mounting seats 52 spaced apart in the circumferential direction. The four groups of positioning bolts 51 extend radially of the insulating shells 3, and pass through the plurality of mounting seats 52 one by one, and are threadedly connected with the corresponding mounting seats 52. One ends of the positioning bolts 51 extend into the optical cable through-holes, and are connected with positioning blocks 53.

[0041] In the above-mentioned implementation scheme, the radial displacement of the positioning block 53 is adjusted by screwing the positioning bolt 51, and the adjustment of multiple positioning bolts 51 allows multiple positioning blocks 53 to clamp and position the accompanying optical cable from all sides. The design is simple, and the accompanying optical cable can be stably positioned. Moreover, the positioning bolts 51 can be adjusted to adapt to the positioning of accompanying optical cables of different sizes.

[0042] In this embodiment, the positioning block 53 is a rubber block. Its texture is relatively soft, which can avoid damage when clamping and positioning the accompanying optical cable.

[0043] As a preferred embodiment, the two ends of one of the magnetic cores 1 protrude from the two ends of the corresponding insulating shell 3, and the two ends of the other magnetic core 1 are respectively located in the two end ends of the corresponding insulating shell 3, and the two ends of one of the magnetic cores 1 are respectively embedded in the two end ends of the other insulating shell 3.

[0044] In the above embodiment, two ends of one magnetic core 1 are embedded in two end heads of another insulating shell 3 , so that the two will not deviate after docking, ensuring good adsorption and docking of the magnetic core 1 .
