Description

Technical Field

[0001] This utility model specifically relates to an underground pipeline detection and positioning instrument, belonging to the field of pipeline detection technology. Background Technology

[0002] With the rapid development of urban construction, underground pipeline systems are becoming increasingly complex, encompassing various types such as water supply and drainage, gas, heating, and electricity. They serve as the "lifeline" of the city, and underground pipeline detection and positioning technology has become crucial for ensuring the normal operation of the city and for pipeline network maintenance and planning. It can quickly and accurately determine whether underground pipelines are damaged. By obtaining this key information, staff can prevent potential safety hazards such as pipeline leaks and ruptures in advance.

[0003] However, current underground pipeline detection and locating instruments are difficult to adapt flexibly to various pipe diameters due to the differences in the inner diameter of different pipes. When facing pipes with larger inner diameters, due to the limited size of the locating instrument, it is difficult for the instrument to fit tightly against the pipe wall, and it is prone to shaking or displacement, making it difficult to maintain a centered position. This situation affects the detection effect. During the shaking process, the direction and intensity of the detection signal emitted by the locating instrument will change, resulting in unstable and inaccurate signals obtained by the receiving end, causing deviations in the pipeline position and direction data, and even misjudgments, so that the detection results cannot truly reflect the actual situation of the pipeline.

[0004] In view of this, this application proposes an underground pipeline detection and locating instrument to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an underground pipeline detection and positioning instrument. Through the design of an adaptive detection mechanism, two sets of active gears synchronously drive three sets of driven gears, which in turn rotate the screw, causing the extension rod to slide linearly within the hollow rod. This adaptively adjusts the extension length, and the pipeline pulley presses against the inner wall to form a three-point support, ensuring that the connecting cylinder is centered and movable for detection. This allows the ultrasonic probe to scan the pipe wall at the optimal distance, thus solving the problems mentioned in the background technology.

[0006] An underground pipeline detection and locating device includes: an adapter detection mechanism comprising an outer cylinder, wherein multiple sets of ultrasonic probes for pipeline detection are provided on one side of the outer cylinder, and an insertion rod for extending the outer cylinder into the pipeline is provided on one side of the outer cylinder; two sets of adapter components are provided inside the outer cylinder, each adapter component comprising three sets of extension square rods that can be synchronously extended and retracted to adapt to the inner diameter of the pipeline; a pipeline pulley is installed at the front end of each extension square rod, and a driven gear is provided at the rear of each extension square rod; every three sets of driven gears are meshed and driven by a driving gear, and two sets of driving gears are connected by a transmission rod to achieve synchronous rotation; and an auxiliary sludge removal mechanism comprising a rotatable conical sludge removal head for clearing sludge blockage in the pipeline, wherein multiple sets of sludge removal teeth for breaking and dispersing sludge are installed on the outer side of the conical sludge removal head.

[0007] In a preferred embodiment, the outer side of the extension rod is provided with multiple sets of scale lines at equal intervals, the rear side of the outer cylinder is equipped with a screw head, the front end of the extension rod is threadedly connected to the screw head, and the extension rod and the screw head are locked together by bolts.

[0008] In a preferred embodiment, each set of driven gears is provided with a set of hollow square rods in front of it, and an extension square rod is slidably disposed inside the hollow square rod. The hollow square rod is fixedly connected to the outer cylinder. The extension square rod is internally threaded with a rotating screw, and the rear end of the rotating screw is fixedly connected to the driven gear. The rotating screw is rotatably connected to the hollow square rod.

[0009] In a preferred embodiment, both the driving gear and the driven gear are bevel gears, and a drive motor is installed at the rear of the outer cylinder, with the output shaft of the drive motor connected to the transmission rod.

[0010] In a preferred embodiment, a connecting cylinder is installed at the front end of the outer cylinder, and multiple sets of ultrasonic probes are installed around the outside of the connecting cylinder.

[0011] In a preferred embodiment, a wireless module is installed inside the connecting cylinder, and the ultrasonic probe is electrically connected to the wireless module.

[0012] In a preferred embodiment, a motor cylinder is connected to the front of the connecting cylinder, and a conical sludge-clearing head is disposed in front of the motor cylinder. A rotary motor is mounted on the motor cylinder, and the output shaft of the rotary motor is fixedly connected to the conical sludge-clearing head.

[0013] Beneficial effects:

[0014] 1. By designing an adaptive detection mechanism, when the detection operation is started, the rotational power of the two sets of driving gears is synchronously transmitted to the three sets of driven gears. Each set of driven gears is coaxially fixed with a rotating screw. As the rotating screw rotates, the extension rod will slide smoothly in a straight line inside the hollow rod, thereby adjusting the extension length of the extension rod according to the inner diameter of the pipe. When the extension rod extends to the appropriate length, the pipe pulley fits tightly against the inner wall of the pipe. Through the three-point support principle, the connecting cylinder is stably held in the center position of the pipe and can also move inside the pipe through the pipe pulley. At this time, the ultrasonic probe installed on the periphery of the connecting cylinder can detect the inner wall of the pipe at the optimal distance. This adaptive detection mechanism realizes rapid adaptive adjustment to pipes with different inner diameters, improving the efficiency of underground pipeline detection.

[0015] 2. By designing an auxiliary sludge removal mechanism, after the adaptive detection mechanism completes adaptive adjustment according to the inner diameter of the pipe, the design of the conical sludge removal head can reduce the resistance of spiraling into the sludge. During operation, the rotary motor drives the conical sludge removal head to rotate and quickly spiral into the sludge blockage position to play a role in unblocking. At the same time, the sludge removal teeth rotate with the sludge removal head, and break and disperse the sludge by cutting through the sludge removal teeth, decomposing large pieces of sludge into small particles, and quickly unblocking the blocked pipe.

Two sets of adapter components 17 are provided inside the outer cylinder 11. The adapter components 17 include three sets of extension square rods 173 that can be synchronously extended and retracted to adapt to the inner diameter of the pipeline. A pipeline pulley 172 is installed at the front end of the extension square rod 173, and a driven gear 175 is provided at the rear of the extension square rod 173. Every three sets of driven gears 175 are meshed and driven by a driving gear 174. Two sets of driving gears 174 are connected by a transmission rod 176 to achieve synchronous rotation. An auxiliary sludge removal mechanism 2 includes a conical sludge removal head 22 that can rotate to clear sludge blockage in the pipeline. Multiple sets of sludge removal teeth 23 for breaking and dispersing sludge are installed on the outside of the conical sludge removal head 22.

[0025] Please see Figures 1-3 As shown, the outer side of the extension rod 14 is provided with multiple sets of scale lines at equal intervals. A screw head 15 is installed on the rear side of the outer cylinder 11. The front end of the extension rod 14 is threadedly connected to the screw head 15, and the extension rod (14) and the screw head 15 are locked together by a bolt 16. The threaded connection between the screw head 15 and the extension rod 14 and the locking by the bolt 16 ensure a stable connection between the extension rod 14 and the outer cylinder 11.

[0026] Please see Figures 1-6As shown, each driven gear 175 is provided with a hollow square rod 171 in front of it, and an extension square rod 173 is slidably disposed in the hollow square rod 171. The hollow square rod 171 is fixedly connected to the outer cylinder 11. The extension square rod 173 is internally threaded with a rotating screw 177, and the rear end of the rotating screw 177 is fixedly connected to the driven gear 175. The rotating screw 177 is rotatably connected to the hollow square rod 171.

[0027] Please see Figure 3 , Figure 4 as well as Figure 6 As shown, both the driving gear 174 and the driven gear 175 are bevel gears. A drive motor 18 is installed at the rear of the outer cylinder 11, and the output shaft of the drive motor 18 is connected to the transmission rod 176.

[0028] Please see Figures 1-3 As shown, a connecting cylinder 12 is installed at the front end of the outer cylinder 11, and multiple sets of ultrasonic probes 13 are installed around the outside of the connecting cylinder 12.

[0029] Please see Figures 1-3 As shown, a wireless module is installed inside the connecting cylinder 12, and the ultrasonic probe 13 is electrically connected to the wireless module. The wireless module can stably transmit the detection data of the ultrasonic probe 13 to the ultrasonic detector through a pre-established wireless connection.

[0030] Please see Figures 1-3 As shown, a motor cylinder 21 is connected to the front of the connecting cylinder 12, and a conical sludge-clearing head 22 is set in front of the motor cylinder 21. A rotary motor 24 is installed on the motor cylinder 21. The output shaft of the rotary motor 24 is fixedly connected to the conical sludge-clearing head 22. The rotary motor 24 drives the conical sludge-clearing head 22 to rotate, which can be screwed into the sludge in the pipe for dredging.

[0031] In practical use, the working principle of this utility model is as follows:

[0032] Before the equipment is put into use, the wireless module must be paired with the ultrasonic detector to establish a wireless connection and enable data transmission. In operation, the operator holds the insertion rod 14 and slowly inserts the outer cylinder 11 into the underground pipe. The scale lines on the outside of the insertion rod 14, marked at 2cm intervals, help determine the depth of the outer cylinder 11 and connecting cylinder 12 into the pipe. This allows for accurate location of any detected anomalies based on the insertion length of the insertion rod 14. Once the outer cylinder 11 is inside the pipe, the drive motor 18 is activated, and its output shaft drives the transmission rod 176 to rotate, causing the two sets of drive gears 174 to rotate synchronously. The drive gears 174 and driven gears 175 are connected via bevel gears. The structure uses meshing transmission to transmit rotational power to three sets of driven gears 175. Since each set of driven gears 175 is coaxially fixed with the rotating screw 177, the rotation of the driven gears 175 drives the rotating screw 177 to rotate synchronously. As the rotating screw 177 rotates, the extension square rod 173 slides smoothly in a straight line inside the hollow square rod 171. Through this transmission process, the extension length of the extension square rod 173 can be adjusted according to the actual inner diameter of the pipe. When the extension square rod 173 extends to the appropriate position, the pipe pulley 172 at the front end fits tightly against the inner wall of the pipe. Using the three-point support principle, the outer cylinder 11 is stably kept in the center position of the pipe, effectively avoiding equipment shaking or displacement during the detection process.

[0033] Subsequently, the connecting cylinder 12 is gradually pushed into the pipeline for inspection using the extension rod 14. The ultrasonic probe 13 emits ultrasonic pulses to the inner wall of the pipeline at a set frequency and receives the reflected echoes. The detection data, including information such as the pipeline wall thickness and internal defects, is transmitted in real time to the wireless module inside the connecting cylinder 12. The wireless module then transmits the data stably to the ultrasonic detector through a pre-established wireless connection for the operator to analyze and process, thereby completing the accurate detection of the underground pipeline.

[0034] When there is blockage and silt in the pipeline, after the inner diameter of the pipeline is adapted by the matching detection mechanism 1, the conical silt-clearing head 22 is rotated by starting the rotary motor 24 during the insertion into the pipeline. The conical silt-clearing head 22 is screwed into the silt to clear it, and the silt-clearing teeth 23 on its outer side break and disperse the silt, so as to achieve efficient silt removal and complete the detection and dredging operation of the underground pipeline.
