Description

Technical Field

[0001] The utility model relates to a pipeline positioning system, in particular to an underground communication pipeline positioning system. Background Art

[0002] Communication lines are the pathways that ensure information transmission. The earliest lines were overhead lines. Due to some defects of overhead lines, later existing technologies usually adopted underground pipelines.

[0003] There are various types of underground pipelines. One type is that during urban construction, trenches are reserved underground for wiring. In this way, the cross-sectional area of ​​the trench is larger, with sufficient space for subsequent upgrades and renovations, and there will also be detailed drawings recording the location of the trench.

[0004] However, there are some cases where there may not be reserved trenches. In this case, if the construction of the communication trunk line is not involved, the trenches of standard specifications will not be opened, but the communication lines will be protected and buried using wire tubes made of corrosion-resistant polymer materials. In this case, due to the small overall specifications of the wire tubes, unknown drift may occur on the one hand, and there may not be detailed drawings to record the distribution position on the other hand, so it is difficult to achieve accurate positioning later.

[0028] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0029] An underground communication pipeline positioning system, such as Figure 1 As shown, including:

[0030] A plurality of metal positioning blocks 2 are arranged along the line tube 1, wherein a communication line is passed through the line tube 1;

[0031] The metal detection device includes a metal detection host 6, a transmitting coil 3 and a receiving coil 4. Figure 2 As shown, the detection host 6 includes a driving circuit 61 and a receiving conditioning circuit 62, the output end of the driving circuit 61 is connected to the transmitting coil 3, the input end of the receiving conditioning circuit 62 is connected to the receiving coil 4, and the transmitting coil 3 and the receiving coil 4 are coaxially arranged.

[0032] By providing the metal positioning blocks 2 arranged along the pipeline 1, a more obvious metal reaction signal can be provided to the metal detection device, so that the underground communication pipeline can be located in the absence of relevant drawings.

[0033] On the whole, the metal detection device constitutes a small metal detector. After the transmitting coil 3 emits a magnetic field, the receiving coil 4 receives the signal reflected by the metal positioning block 2 and other external objects. Since the metal positioning block 2 is a large conductor, the presence or absence of the metal positioning block 2 will cause a huge difference in the signal received by the receiving coil 4. Therefore, it can be known whether the transmitting coil 3 and the receiving coil 4 are aligned with the metal positioning block 2. When the reflected signal is most obvious, the metal positioning block 2 is directly below the coil, which is the position of the wire tube 1. Then, multiple metal positioning blocks 2 are found in turn, and a scatter plot of the wire tube 1 can be obtained.

[0034] Generally, since the direction of the wire tube 1 is mostly straight, after finding two metal positioning blocks 2, starting from the third metal positioning block 2, a more accurate range can be obtained, which can improve efficiency.

[0035] In some embodiments, the metal positioning blocks 2 are arranged at equal intervals along the line tube 1 , so that the efficiency can be further improved starting from the third metal positioning block 2 .

[0036] Generally, in some embodiments, the metal positioning block 2 is placed in a plastic box, which has a better anti-corrosion effect, but the processing cost of this method is high, and the metal positioning block 2 needs to be loaded into the plastic box. Therefore, in other embodiments, the surface of the metal positioning block 2 is coated with a corrosion-resistant paint layer, so as to have a certain anti-corrosion effect while reducing costs. This paint layer can be a multi-layer paint, including an electrophoretic layer, etc.

[0037] In a certain embodiment, the distance between adjacent metal positioning blocks 2 is 1 meter. Of course, in some other embodiments, it can also be other values, such as 2 meters.

[0038] Furthermore, in most embodiments, Figure 1 As shown, the metal detection device also includes an operating rod 5. Based on this operating rod 5, the convenience can be further improved. The operating rod 5 can be held to operate. The transmitting coil 3 and the receiving coil 4 are fixed to one end of the operating rod 5, and the transmitting coil 3 is located above the receiving coil 4. The receiving coil 4 is closer to the metal positioning block 2 and is more sensitive in the metal area. In addition, in other embodiments, two receiving coils 4 can also be provided, and the two receiving coils 4 are respectively located on both sides of the transmitting coil 3 and are symmetrically arranged.

[0039] Generally, in most embodiments, the detection host 6 also includes a plane of the transmitting coil 3 and an angle between the operating rod 5 of 70° to 85°, so that the operation is more coordinated.

[0040] In addition, in some embodiments, the detection host 6 also includes a shell and a shoulder strap disposed on the shell, and the drive circuit 61 and the receiving conditioning circuit 62 are both placed in the shell, which can be carried on the shoulder, making the operation more convenient, and the positioning can be completed by a single person. Generally, the metal positioning block 2 is in the shape of a regular polyhedron, for example, the metal positioning block 2 is in the shape of a cube.
