[0018] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0019] This embodiment provides a technical solution: a new pipeline deformation monitoring device during foundation pit excavation, such as Figure 1 As shown, it includes an electromagnetic adsorption moving rod 1, which is connected to two symmetrically arranged main trunks 12 through the original magnetic force. The electromagnetic adsorption moving rod 1 and the two main trunks 12 are fixed by magnetic attraction, so that the two main trunks 12 can be conveniently connected and fixed to facilitate later maintenance. The main trunk 12 is a hollow structure, and the two ends of the electromagnetic adsorption moving rod 1 are respectively inserted into the interior of the two main trunks 12. A total of three conical covers 3 are fixed on the two main trunks 12, wherein two conical covers 3 are respectively fixed to the outer ends of the two main trunks 2 (i.e., the first conical covers), and the other conical cover 3 is fixed to the inner end of one of the main trunks 2 (i.e., the second conical cover).

[0020] A plurality of annularly distributed turning support rods 4 are installed on the outer sides of the three conical covers 3, and one end of the turning support rod 4 is connected to the conical cover 3 by a hinge, a spring 5 is connected between the other end of the turning support rod 4 (i.e. the first turning support rod) on the conical covers 3 on both sides and the conical cover 3, and a first telescopic rod 6 is connected between the turning support rod 4 (i.e. the second turning support rod) on the middle conical cover 3 and the conical cover 3; the first telescopic rod 6 or the spring 5 is extended and retracted to fit the size of the pipeline, and can be adapted to the clamping and fixing of pipelines with different inner diameters, thereby improving the applicability of the device.

[0021] A mounting seat 7 is installed on both trunks 2. The mounting seat 7 is a ring structure, and steel brushes 8 are evenly distributed on the outer surface of the mounting seat 7. The steel brushes 8 are used to clean the gaps at the deformed parts of the pipeline, which improves the overall function and is less affected by the environment. The steel brushes 8 can adaptively deform according to the size of the pipeline. The second telescopic rod 11, the conical cover 3 and the mounting seat 7 are all connected and fixed to the trunk 2 through multiple ladder columns 10.

[0022] The end with a smaller diameter of the conical cover 3 is the front end, and the end with a larger diameter is the rear end. The rear trunk 2 is hollow inside and contains a battery 9. A circular ring is welded to the outer surface of the two trunks 2, and the circular ring contains a laser detector 13. The model containing the laser detector 13 is the Keyence ultra-high-speed contour measuring instrument LJ-V7000 series.

[0023] The lasers of the two laser detectors 13 are emitted along the axial direction of the pipeline, and can detect the axial deformation of the pipeline, with high sensitivity and accuracy. However, in some special cases, such as when the deformation of the pipeline is very small or the deformation speed is very fast, the monitoring accuracy may be affected, but the impact will be smaller. In this implementation, regular maintenance is convenient, the pipeline deformation monitoring device is easy to disassemble, and regular maintenance and calibration are convenient, ensuring its normal operation and extending its service life.

[0024] A button switch (not shown in the figure) is installed in the middle of the electromagnetic adsorption moving rod 1. A layer of glass is contained outside the button switch to effectively protect the button switch from damage. The button switch is electrically connected to the laser detector 13. The function of the button switch is to turn on the laser detector 13.

[0025] Furthermore, the conical cover 3 has a groove, and the ladder column 10 is embedded and fixed with the conical cover 3.

[0026] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
