Description

Technical Field

[0001] The invention relates to the technical field of pipeline ground penetrating radar positioning and early warning, and in particular to a ground penetrating radar positioning and early warning device for underground pipelines. Background Art

[0002] In the complex environment of underground pipeline management and maintenance, it is crucial to accurately and timely locate the status of underground pipelines and warn of potential risks. Traditional pipeline monitoring methods mostly rely on vibration sensors, which assess the safety status of underground pipelines by detecting tiny vibrations on the ground. However, this single monitoring method has obvious limitations.

[0003] Although vibration sensors can capture vibration signals on the ground, it is often difficult to accurately determine the source of the vibration, that is, it is impossible to distinguish whether the vibration is caused by pipeline problems (such as leakage, damage) or external environmental factors (such as traffic, construction, etc.). This uncertainty may lead to false alarms or missed alarms, affecting the accuracy and reliability of the early warning system. Summary of the invention

[0004] 1. Purpose of the invention

[0005] In view of this, the purpose of the present invention is to provide a ground penetrating radar positioning and early warning device for underground pipelines, which solves the problems raised in the above background.

The setting of the display screen 913 and multiple groups of operation buttons 912 enables the operator to intuitively view the device status, parameter settings and receive warning information, while facilitating manual control and adjustment, thereby improving user experience and operational convenience.

[0036] Furthermore, the fixing seat 915 is fixedly connected to the second motor 916 , and the fixed connection ensures the stable operation of the second motor 916 .

[0037] Furthermore, a limiting plate 914 is fixedly installed on one side of the two sets of fixed seats 915, and a sliding groove is provided on the outer surface of the limiting plate 914, and a slide plate 919 is movably engaged with the inner wall of the sliding groove. The design of the limiting plate 914 and its sliding groove further limits the movement range of the slide plate 919, prevents mechanical failure or damage caused by excessive movement, and ensures the stable operation of the device.

[0038] Working principle: First, the ground penetrating radar positioning and early warning device for underground pipelines is firmly installed on the surface through the screw groove 114 on the outer surface of the support plate 211, ensuring that the fixed pipe 411 can be close to and approach the position of the target underground pipeline. During the installation process, multiple groups of soil pressure sensors 214 are synchronously installed at appropriate locations on the surface or underground, and connected to the circuit control board inside the fixed shell 3 through the connecting data line 213. These soil pressure sensors 214 constitute a preliminary monitoring network for underground environmental changes. When the soil pressure changes due to underground pipeline leakage, damage or other external factors such as geological changes, construction activities, etc., the soil pressure sensors 214 can capture these subtle changes in real time and transmit the signals to the circuit control board for processing. The circuit control board analyzes these signals through a built-in algorithm, and once an abnormal pressure change is identified, the early warning mechanism is immediately triggered.

[0039] At the same time, in order to more accurately locate and evaluate the status of the underground pipeline, the CPU control module inside the device will start the automatic adjustment function of the vibration sensor 923 according to the feedback of the soil pressure sensor 214. After receiving the control signal, the second motor 916 drives the screw rod 917 to rotate. This rotational motion is converted into the up and down linear motion of the sliding seat 918 through the threaded cooperation between the screw rod 917 and the sliding seat 918. The up and down movement of the sliding seat 918 drives the slide plate 919 and its connected connecting pipe 920 and the detection rod 922, so that the vibration sensor 923 can adjust its position up and down within a certain range underground to meet the monitoring needs of different depths.

[0040] As the position of the vibration sensor 923 is adjusted, it can more accurately capture vibration signals from underground pipelines. These vibration signals may be caused by pipeline leakage, damage, water flow impact, etc., or may be interference caused by external construction, vehicle driving, etc. The vibration sensor 923 transmits the captured vibration signals to the line control board for further processing and analysis.

[0041] The CPU control module combines the location information provided by the GPS positioning module, as well as the real-time data of the vibration sensor 923 and the soil pressure sensor 214, to comprehensively evaluate the safety status of the underground pipeline. Once it is determined that there is a potential risk or abnormal situation, the device will immediately send an early warning signal to the monitoring center through the wireless communication module, and trigger the sound alarm 7 and the light alarm 8 to provide an emergency prompt on site in the form of sound and light. When the device detects an abnormal situation, it not only sends an early warning signal to the monitoring center through the wireless communication module, but also triggers the sound alarm and the light alarm on site to provide an emergency prompt in the form of sound and light. This dual early warning method can quickly attract the attention of on-site personnel and improve the speed of emergency response.

[0042] In addition, the display screen 913 and multiple groups of operation buttons 912 provided on the outer surface of the fixed shell 3 provide the operator with an intuitive monitoring interface and convenient operation mode, which is convenient for parameter setting, status viewing and manual control, etc. The entire device is powered by a solar panel 911 to ensure stable operation even when unattended for a long time, and uses batteries for energy storage to cope with insufficient sunlight or continuous rainy weather.
