[0002] With the continuous development of urban construction, the number of underground pipelines is increasing, and underground pipelines bear the task of transmitting resources such as water and gas in the city.

[0039] The fixing mechanism includes a fixing frame 101, fixing rods 102 and fixing rings 103. Fixing rods 102 are fixedly installed at the four corners of the fixing frame 101, and fixing rings 103 are fixedly installed on each fixing rod 102. The fixing rings 103 are connected to the program control box. Detection frame one 201 and detection frame two 301 are both fixedly installed on the fixing frame 101.

[0040] The working principle of this invention is as follows:

[0041] The fixing frame 101 is fixedly installed in the soil by multiple fixing rods 102. The multiple fixing rods 102 are respectively fixed in the ground by corresponding fixing rings 103. The program control box is installed on the multiple fixing rings 103. The pipeline assembly includes pipe one 801 and pipe two 803. Pipe one 801 and pipe two 803 are connected by flange connection assembly 802. The detection plate 703 is in contact with the flange connection assembly 802. The two detection half rings 601 on both sides of pipe one 801 or pipe two 803 form a circle that matches pipe one 801 or pipe two 803. Multiple pressure heads 604 are in contact with pipe one 801 or pipe two 803.

[0042] In this embodiment: Figure 2The horizontal direction along pipe 801 is the front-back direction, the vertical direction along fixed rod 102 is the up-down direction, and the direction perpendicular to both the horizontal direction of pipe 801 and the vertical direction of fixed rod 102 is the left-right direction (i.e., Figure 2 (The direction perpendicular to the paper).

[0043] Initially, springs 4 (503) and 5 (505) are compressed. Under the elastic force of spring 4 (503), the fixing block 3 (504) tends to move towards pipe 1 (801) or pipe 2 (803). Under the elastic force of spring 5 (505), the torque sensor 506 tends to move towards pipe 1 (801) or pipe 2 (803). Thus, under the action of fixing block 3 (504) and torque sensor 506, the friction wheel 507 is pressed tightly against pipe 1 (801) or pipe 2 (803). Since multiple anti-slip strips are provided on the friction wheel 507, there is a frictional force between pipe 1 (801) or pipe 2 (803) and the friction wheel 507, which can drive the friction wheel 507 to rotate when pipe 1 (801) or pipe 2 (803) moves.

[0044] When pipe 1 801 or pipe 2 803 moves in the front-to-back direction: When pipe 1 801 or pipe 2 803 moves, the friction wheel 507 rotates under the action of friction. When the friction wheel 507 rotates, the torque sensor 506 provides real-time feedback on the torque. At the same time, the friction wheel 507 drives the pointer 509 to rotate. The pointer 509 and the dial 508 work together to provide real-time feedback on the angle value of the pointer 509's rotation. When the torque value on the torque sensor 506 or the angle value on the pointer 509 reaches the alarm value (the alarm value is set in advance), the program control system sends an alarm signal to the server, which facilitates timely troubleshooting.

[0045] Simultaneously, pipe 1 801 or pipe 2 803 drives flange connection assembly 802 to move. When flange connection assembly 802 moves, it drives detection plate 703 to move. When detection plate 703 moves, it squeezes pressure sensor 5 705 through spring 704. Pressure sensor 5 705 provides real-time feedback of pressure value. When the pressure value reaches the alarm value (pre-set alarm value), the program control system sends an alarm signal to the server, which facilitates timely troubleshooting.

[0046] Furthermore, the fourth and sixth detection units can detect and provide feedback on multiple parameters in real time when pipeline 1 (801) or pipeline 2 (803) is displaced in the front-to-back direction. This facilitates timely, stable, and accurate detection of whether the displacement value of pipeline 1 (801) or pipeline 2 (803) exceeds the standard, enabling timely handling and maintenance of the pipeline and improving the safety of the pipeline during use.

[0047] When pipe 1 (801) or pipe 2 (803) shifts in the left or right direction: pipe 1 (801) or pipe 2 (803) compresses spring 6 (607) through pressure head 604, and spring 6 (607) compresses pressure sensor 4 (603), thus the pressure value is fed back in real time through pressure sensor 4 (603). When the pressure value reaches the alarm value (pre-set alarm value), the program control system sends an alarm signal to the server; at the same time, the detection semi-ring 601 drives the fixed block 1 (402) to move through support block 2 (605), and the fixed block 1 (402) drives the sliding frame 401 to move through detection shaft 403. The sliding frame 401 is driven by spring... Pressure sensor 302 is pressed by pressure block 303, which provides real-time feedback of the pressure value. When the pressure value reaches the alarm value (pre-set alarm value), the program control system sends an alarm signal to the server. At the same time, support block 605 and support shaft 606 drive slider 204 to move via connecting rod 205. Slider 204 causes pressure sensor 202 to generate a pressure value via spring 203, which provides real-time feedback of the pressure value. When the pressure value reaches the alarm value (pre-set alarm value), the program control system sends an alarm signal to the server.

[0048] Furthermore, the second, third, and fifth detection units can detect and provide feedback on multiple parameters in real time when pipe 1 801 or pipe 2 803 is displaced in the left and right directions. The feedback of multiple parameters can accurately and effectively indicate whether the displacement of pipe 1 801 or pipe 2 803 in the left and right directions exceeds the standard, which greatly ensures the accuracy of the detection results.

[0049] When pipe 1 801 or pipe 2 803 moves vertically: pipe 1 801 or pipe 2 803 compresses spring 607 via pressure head 604, and spring 607 compresses pressure sensor 4 603, thereby providing real-time feedback of the pressure value through pressure sensor 4 603. When the pressure value reaches the alarm value (pre-set alarm value), the program control system sends an alarm signal to the server; simultaneously, detection semi-ring 601 drives fixed block 1 402 to move via support block 2 605, and fixed block 1 402 drives spring 3 405 to compress the pressure sensor via detection shaft 403. Sensor 3 404 provides real-time feedback of the pressure value. When the pressure value reaches the alarm value (pre-set alarm value), the program control system sends an alarm signal to the server. Simultaneously, support block 2 605 and support shaft 606 move slider 1 204 via connecting rod 205. Slider 1 204, through spring 203, causes pressure sensor 1 202 to generate a pressure value, which is then fed back in real-time by pressure sensor 202. When the pressure value reaches the alarm value (pre-set alarm value), the program control system sends an alarm signal to the server.

[0050] Furthermore, the first, third, and fifth detection units can detect and provide feedback on multiple parameters in real time when pipe 1 801 or pipe 2 803 is displaced in the vertical direction. The feedback of multiple parameters can accurately and effectively indicate whether the displacement of pipe 1 801 or pipe 2 803 in the horizontal direction exceeds the standard, which greatly ensures the accuracy of the detection results.

[0051] In addition, if pipe 1 801 or pipe 2 803 simultaneously displaces in the left-right or up-down direction, and the displacement causes slider 1 204 to move in one direction (the movement principle of slider 1 204 is explained above), pressure sensor 1 202 will also trigger an alarm when it reaches the alarm value. Therefore, it is possible to detect the positional changes of pipe 1 801 or pipe 2 803 simultaneously displacing in the left-right or up-down direction, and the displacement causes slider 1 204 to move in one direction. Multiple parameters can be used to measure whether the underground pipeline displacement exceeds the standard, further ensuring the accuracy of pipeline displacement detection.

[0052] It should be noted that the feedback of the above-mentioned parameter values ​​and the overall working process of this invention are controlled by an external server and a program control system.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
