Description

Technical Field

[0001] This invention relates to the field of underground pipeline leak detection equipment, and more specifically, to a ground-mounted underground pipeline network leak monitoring device. Background Technology

[0002] Underground pipelines are pipes laid underground to transport liquids, gases, or loose solids. These pipelines intertwine to form a network. Modern underground pipelines come in a wide variety of cross-sectional shapes, including circular, elliptical, semi-elliptical, multi-centered, oval, rectangular, and horseshoe shapes. They are constructed using materials such as steel, cast iron, concrete, reinforced concrete, prestressed concrete, brick, stone, asbestos cement, clay, plastic, and fiberglass. Over time, underground pipelines can leak due to aging, corrosion, and erosion. Because they are buried underground, workers cannot visually inspect for leaks and require leak detection devices to locate them. The underground pipeline leak monitoring device consists of an earpiece, a monitoring host, and a monitoring head. When in use, the staff wears the monitoring host around their neck, the earpiece connected to the monitoring host on their ears, and then holds the detection head and places it on the ground above the pipeline for monitoring. The detection head then collects sound and transmits it to the monitoring host. The monitoring host processes the sound and transmits it back to the staff through the earpiece for analysis. If the sound increases significantly, it indicates a leak, and the staff marks the location on the ground. If the sound does not increase, it indicates no leak. The staff then moves the detection head forward a certain distance along the direction of the pipeline until the monitoring work is completed.

[0003] However, existing underground pipeline leak monitoring devices require personnel to wear them and operate them at close range. This puts a heavy burden on the personnel, leading to fatigue and frequent breaks, which slows down the detection speed. Moreover, in the hot summer, personnel have to work under the scorching sun, which directly exposes them to the sun and causes significant harm to their health. In addition, the distance the detection head moves is related to the pipe material. Different pipe materials require different distances for the detection head to move. Manually moving the detection head cannot accurately control the distance. If the distance is too short for a specific pipe material, it will increase the number of detection points and monitoring data, increasing the detection burden and slowing down the detection speed. If the distance is too long, it will easily lead to missed detections. Therefore, there is an urgent need to design a ground-mounted underground pipeline leak monitoring device. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] Existing underground pipeline leak monitoring devices require personnel to wear them and operate them at close range, resulting in heavy loads, fatigue, frequent breaks, and slowed detection speed. Furthermore, in hot summers, workers are exposed to direct sunlight, causing significant health risks. Additionally, the distance the detection head moves is dependent on the pipe material; different materials require different distances. Manual movement of the detection head cannot accurately control the distance. Too short a distance increases the number of detection points and monitoring data, increasing the workload and slowing down detection, while too long a distance can lead to missed detections. The purpose of this invention is to provide a ground-mounted underground pipeline leak monitoring device that effectively solves the problems mentioned in the background art.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of this invention are:

[0017] 1. By using a ground-mounted detector, the underground pipeline leak detection device can move forward along the pipeline's direction without requiring personnel to carry it. This significantly reduces the load on workers, minimizing fatigue and reducing the frequency of rest, thus accelerating the detection speed. Furthermore, workers can remotely control the combined drive through the ground-mounted detector.

The moving ground-mounted component moves the detection head downwards, allowing it to touch the ground for detection. Workers can control the device from a distance in the shade, avoiding exposure to direct sunlight and reducing the risk of injury. This makes the device more worker-friendly and improves the practicality of the underground pipeline leak detection device.

[0018] 2. The distance recorder can monitor the distance traveled by the ground-mounted underground pipeline leak detection device in real time each time, eliminating the need for manual movement of the detection head. The distance traveled is precise and controllable, avoiding problems caused by the detection head moving too short or too long. This ensures that the ground-mounted underground pipeline leak detection device can complete the detection work efficiently, with high quality and quantity. Through the point adjustment mechanism, the staff can adjust the distance traveled by the ground-mounted underground pipeline leak detection device each time according to different pipe materials, improving its applicability. Through the reset component, the distance recorder can remeasure the distance after each detection by the ground-mounted underground pipeline leak detection device, ensuring the continuous progress of the detection work, helping to increase the detection speed, and improving the practicality of the ground-mounted underground pipeline leak detection device.

[0039] Working principle:

[0040] First, the adjusting screw 64 is rotated by adjusting the disc 68. Then, the dot-matrix slide 62 moves under the action of the threaded engagement between it and the adjusting screw 64. Next, the dot-matrix slide 62 moves along with the dot-matrix push-button switch 63 and the shuttle-shaped pointer 66. Then, the position of the shuttle-shaped pointer 66 relative to the scale mark 67 is observed. The distance marked by the position of the shuttle-shaped pointer 66 relative to the scale mark 67 is the distance traveled by the ground-mounted underground pipeline leak detection device in one go. Then, the position of the shuttle-shaped pointer 66 relative to the scale mark 67 is adjusted according to the material of the pipeline until the position of the shuttle-shaped pointer 66 relative to the scale mark 67 is adapted to the material of the pipeline. Then, the ground-mounted underground pipeline leak detection device is placed on the ground above the pipeline, and then the pipeline is connected through the terminal. The trajectory information is sent to the wireless transmitter 107, which then transmits the pipeline trajectory information to the intelligent controller 108. A terminal then controls the intelligent controller 108 via the wireless transmitter 107, causing the intelligent controller 108 to initiate a detection program. The intelligent controller 108 then controls the monitoring host 103 to operate. Next, the intelligent controller 108 controls the linkage drive motor 34 to run forward. The linkage drive motor 34 then rotates the combined drive gear 35. The combined drive gear 35, through its meshing with the combined drive ring gear 32, rotates the combined drive ring gear 32. The combined drive ring gear 32, through its meshing with the changeover gear 25, rotates the changeover gear 25. Finally, the changeover gear... 25 rotates relative to the conversion screw 26, and then the conversion screw 26 moves upward under the action of its threaded engagement with the conversion gear 25. Next, the conversion screw 26 moves upward with the annular piston 27. Afterward, the air pressure above the annular piston 27 gradually increases. Since the ground-contact air chamber 42 is connected to the conversion annular chamber 20 through the constant pressure bend 43, the air pressure above the lifting piston 45 increases. Then, the lifting piston 45 moves downward under the push of the air pressure and squeezes the lifting spring 44. The lifting spring 44 is elastically compressed, and its elastic potential energy increases. Then, the lifting piston 45 moves downward with the lifting support rod 46. Afterward, the lifting support rod 46 moves downward with the lifting cross plate 47. Then, the lifting cross plate 47 moves downward with the detection head 105. Then, the detection head 105 moves downward. The detector head 105 moves vertically downwards until its bottom surface touches the ground. The air pressure inside the annular cavity 20 continues to increase. The pressure sensor 28 monitors the pressure value in real time and sends it to the intelligent controller 108. When the pressure inside the annular cavity 20 reaches the preset maximum value within the intelligent controller 108, the intelligent controller 108 controls the linkage drive motor 34 to stop. At this point, the intelligent controller 108 starts timing. The monitoring host 103 then collects detection information through the detection line 104 and the detector head 105. The monitoring host 103 then transmits the collected information to the terminal via the wireless transmitter 107. The staff listens to the information and analyzes it. When the staff determines that a leak has occurred in the pipeline at the detection point based on the information...After the staff moves to the location of the ground-mounted underground pipeline leak detection device, marks it, and returns, the device continues its detection work. Once the staff determines that there is no leak in the pipeline at the detection point based on the information, no further action is required; the device continues its detection work until the detection time reaches the preset value inside the intelligent controller 108. Then, the intelligent controller 108 controls the linkage drive motor 34 to run in reverse, causing the annular piston 27 to move downwards. The air pressure above the annular piston 27 and the lifting piston 45 decreases. Then, under the elastic force of the lifting spring 44, the lifting piston 45 moves upwards via the lifting support rod 46 and the lifting crossbar 47, carrying the detection head 105 until the detection head is reached. The top surface of the probe 105 rests against the bottom surface of the limiting transverse plate 48. At this time, the bottom end of the probe 105 is far from the ground, and the air pressure above the annular piston 27 reaches the minimum value preset inside the intelligent controller 108. Then, the intelligent controller 108 controls the linkage drive motor 34 to stop running. Then, the intelligent controller 108 controls the electric steering wheel 110 and the electric walking wheel 111 to run, so that the ground-level underground pipeline leakage monitoring device moves forward along the pipeline trajectory. During this process, the distance recording plate 501 moves downward through the distance recording tube 504 with the U-shaped recording element 505 under the elastic tension of the compression spring 72. Then, the U-shaped recording element 505 moves downward through the distance recording transverse axis 506 with the distance recording wheel 507. After that, the distance recording... Wheel 507 presses against the ground, and then the ground-hugging carriage 101, through the connection of guide rail 503 and guide groove 502, moves the distance recording horizontal axis 506 forward via distance recording plate 501, distance recording tube 504, and U-shaped recording component 505. Next, distance recording wheel 507 rolls under the friction between itself and the ground. Then, distance recording wheel 507 rotates the distance recording horizontal axis 506, which in turn rotates the recording line wheel 508. Next, the recording lead 509 winds around the outside of the recording line wheel 508, pulling the recording slide plate 512 to the right. Then, the recording slide plate 512 compresses the return spring 514, causing the return spring 514 to compress elastically, increasing its elastic potential energy. Finally, the recording slide plate 512 moves the recording line wheel 506 forward. The pressure bar 513 moves to the right, then contacts the point-press switch 63 and applies pressure. The point-press switch 63 is then triggered and sends a signal to the intelligent controller 108. The intelligent controller 108 then stops the electric steering wheel 110 and electric travel wheel 111. Next, the intelligent controller 108 controls the linkage drive motor 34 to run forward, causing the detection head 105 to rest against the ground at the second measuring point and complete the detection. Then, the intelligent controller 108 controls the linkage drive motor 34 to run in reverse, causing the detection head 105 to reset upwards. Finally, the intelligent controller 108 controls the electromagnetic telescopic rod 73 to shorten, and then the electromagnetic telescopic rod 73 moves upwards along with the U-shaped lifting fastener 74.Then, the U-shaped lifting fastener 74 moves the U-shaped recording component 505 upwards. Next, the U-shaped recording component 505, via the distance recording axis 506, lifts the distance recording wheel 507 off the ground. Then, under the force of the return spring 514, the recording slide plate 512 moves the recording pressure bar 513 to the left and pulls the recording lead 509. The recording lead 509 is then released from the outside of the recording line wheel 508 until the recording slide plate 512 moves to its extreme left position. Finally, the intelligent controller 108 controls the electromagnetic telescopic rod 73 to extend. Then, the electromagnetic telescopic rod 73 moves downwards along with the U-shaped lifting fastener 74. Next, under the force of the compression spring 72, the distance recording plate 501 moves downwards along with the distance recording wheel 507 via the distance recording tube 504, the U-shaped recording component 505, and the distance recording horizontal axis 506, until the distance recording wheel 507 is pressed back onto the ground, causing the distance recorder 5 to re-measure. Then, the intelligent controller 108 controls the electric steering wheel 110 and the electric walking wheel 111 to operate. This process is repeated until the detection is complete.
