[0022] Reference Figure 1-4This utility model discloses a precise positioning device for buried gas pipelines, comprising: a gas pipe 1 and a signal transmitting component. An mounting plate 8 is provided on the upper surface of the gas pipe 1. The mounting plate 8 provides a mounting base for other components and serves as an important carrier connecting the gas pipe 1 to various functional components. Sleeves 9 are fixedly connected to the four corners of the upper surface of the mounting plate 8. The sleeves 9 act as support and guide structures, providing a stable spatial frame for the movement of subsequent components such as the sliding plate 13. Slide grooves 10 are provided on both the front and rear sides of the outer surface of the sleeves 9. The slide grooves 10 provide a track for the sliding of the connecting block 15, allowing the connecting block to move smoothly. Block 15 can move along a specified path. A connecting groove 14 is provided on the lower surface of the slide 10. The connecting groove 14 cooperates with the connecting block 15 to ensure that the connecting block 15 can smoothly pass through the groove when moving vertically, achieving linkage with other components. A first positioning post 11 is fixedly connected to the inner surface of the sleeve 9. The first positioning post 11 provides guidance and positioning for the sliding plate 13, ensuring that the sliding plate 13 slides smoothly along a straight line. The sliding plate 13 is slidably connected to the outer surface of the first positioning post 11. The sliding plate 13 drives the connecting block 15 and other components to move by sliding on the first positioning post 11, thereby achieving the relevant functions. The upper surface of the sliding plate 13 is in contact with a spring 12, which provides a restoring force to the sliding plate 13, allowing it to return to its initial position when no external force is applied, thus ensuring the stability of the device. The spring 12 is of moderate size and is not easily shaken, making it less likely to lose its performance. Connecting blocks 15 are fixedly connected to both the front and rear sides of the sliding plate 13. The connecting blocks 15 connect the sliding plate 13 to components such as the second positioning post 16, transmitting the movement of the sliding plate 13. A second positioning post 16 is fixedly connected between the two connecting blocks 15. The second positioning post 16 provides a support structure for the installation and rotation of the roller 17. The outer surface of the second positioning post 16 rotates... The device is connected to a roller 17, which makes contact with the ground by rolling, reducing friction when the device moves and assisting in positioning and movement. A locking block 6 is fixedly connected to the upper surface of the mounting plate 8. The locking block 6 is used to fix and install the remote receiving device 5, enabling it to work stably and receive relevant signals. The remote receiving device 5 is locked to the inner surface of the locking block 6. The remote receiving device 5 is used to receive signals from the pulse signal generator 3 to achieve precise positioning of the gas pipeline. A protective cover 7 is fixedly connected to the lower surface of the mounting plate 8. The protective cover 7 is used to protect the gas pipe 1 and related internal components from damage caused by external factors.

[0023] The protective cover 7 is located between the two sleeves 9. This positioning allows the protective cover 7 to effectively cover critical areas, enhancing the protective effect. Two connecting slots 14 are symmetrically arranged on the front sides of the sleeves 9. This symmetrical arrangement ensures even force distribution on the connecting blocks 15, making the sliding plate 13 move more smoothly. The number of connecting blocks 15 corresponds to the number of connecting slots 14, ensuring that the connecting blocks 15 can slide smoothly within the connecting slots 14, achieving normal device function. Rollers 17 are located below the sliding plate 13. Driven by the sliding plate 13, the rollers 17 can contact the ground, moving the device through rolling. A locking block 6 is located above the protective cover 7. The locking block 6 and the protective cover 7 are distributed vertically, protecting and fixing different components respectively, improving the overall safety and stability of the device. The interior of the locking block 6 is connected to the interior of the protective cover 7. This connection design facilitates the layout of internal wiring and signal transmission, making the internal structure of the device more rational. A signal transmitting component is installed at one end of the gas pipe 1. The transmitting component is used to generate and transmit signals, providing a signal source for gas pipeline positioning. The signal transmitting component includes valve 2, pulse signal generator 3, and connecting line 4. Valve 2, pulse signal generator 3, and connecting line 4 cooperate with each other to form a complete signal transmitting system. One end of gas pipe 1 is fixedly connected to valve 2. Valve 2 is not only used to control the flow of gas, but also provides an installation position for pulse signal generator 3. Pulse signal generator 3 is installed on the side wall of valve 2. Pulse signal generator 3 generates pulse signals, which are transmitted through connecting line 4. It is the core component for achieving precise positioning of gas pipeline. The output of pulse signal generator 3 is fixedly connected to connecting line 4, and connecting line 4 is movably connected to valve 2. Connecting line 4 is used to transmit the signals generated by pulse signal generator 3. The movable connection method facilitates installation and maintenance. Mounting plate 8 is located above gas pipe 1. This positional relationship allows mounting plate 8 to effectively support and install other components without affecting the normal operation of gas pipe 1.

[0024] Working principle: First, the ground inspection personnel start the inspection equipment and send a inspection command to the pulse signal generator 3 to generate a detection pulse signal. The signal is transmitted through the connecting line 4, and the remote receiving device 5 receives the signal and feeds it back to the ground inspection equipment. If the signal transmission is abnormal, check whether the moving connection between the connecting line 4 and the valve 2 is loose, or whether the pulse signal generator 3 is malfunctioning due to the underground environment. Repair or replace it in time. Apply external force to the sliding plate 13 through the ground inspection equipment and observe its sliding along the first positioning column 11. If the sliding is not smooth, check whether the spring 12 has lost its elasticity due to underground pressure or corrosion, whether there is any jamming between the connecting block 15 and the sliding groove 10 and connecting groove 14 of the sleeve 9, and whether the roller 17 rotates flexibly on the second positioning column 16. Replace worn or damaged parts, such as the spring 12 and roller 17, to ensure that the device can move normally in subsequent positioning operations. Open the protective cover 7 to check the internal gas pipe 1 and related components, and check whether the protective cover 7 is damaged by underground soil. Damage caused by compression or groundwater erosion should be repaired or replaced promptly if cracks or corrosion are found. Simultaneously, check the secure connection between the locking block 6 and the remote receiving device 5, and ensure the wiring connecting the locking block 6 and the protective cover 7 is undamaged. This ensures the safety of internal components and stable signal transmission. After completing the above component inspections, restart the pulse signal generator 3 to generate a positioning pulse signal. The ground detection equipment receives the signal from the remote receiving device 5 and, combined with the movement of the roller 17 auxiliary device, recalibrates the position of the buried underground gas pipe 1. If the positioning deviation exceeds the allowable range, adjust the device position or check the accuracy of each component connection until the positioning accuracy meets the requirements. Thoroughly inspect the installation and connection of each component to ensure there is no looseness or damage. Start the entire device and perform multiple simulated positioning operations, observing the coordinated operation of the pulse signal generator 3, the remote receiving device 5, the sliding plate 13, and the roller 17 to confirm that the maintained device can accurately position the buried gas pipe 1.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
