Description

Technical Field

[0001] This utility model relates to the technical field of metal pipeline detectors, and in particular to a high-power metal pipeline detector. Background Technology

[0002] A metal pipeline detector is a specialized device that uses the principle of electromagnetic induction to detect the location and direction of underground metal pipelines. It mainly consists of a transmitter and a receiver. The transmitter generates an alternating magnetic field, which induces a current within the underground metal pipeline, thus generating a secondary magnetic field. The receiver receives this secondary magnetic field to determine the pipeline's location. It has wide applications in many fields, including urban construction, infrastructure maintenance, the oil and gas industry, and archaeological excavation. However, in some complex situations, such as detecting deeply buried large municipal or industrial pipelines, detecting long-distance pipelines over large areas, or in environments with abundant mineral deposits or groundwater interference, ordinary power detectors cannot meet the requirements. In these cases, high-power metal pipeline detectors are needed. Their high power output allows for deeper detection depths and wider detection ranges, effectively penetrating complex geological interference to accurately detect deeply buried metal pipelines, improving work efficiency and detection accuracy.

[0003] When using a traditional high-power metal pipeline detector, the transmitter is first set up in the target area. Parameters such as power and frequency are adjusted (generally, a lower frequency is chosen for deep detection based on the detection depth and geological conditions). The transmitting coil is then connected and placed in a suitable location to generate an alternating magnetic field. The receiver is then turned on, and the receiver is held hand-held and moved around the detection area using its receiving antenna. The receiver amplifies and filters the secondary magnetic field signal induced by the metal pipeline detected by the antenna. The location and direction of the underground metal pipeline are determined by observing the graphics and numbers on the receiver's display screen or listening to changes in the audio output (a stronger signal results in a louder sound). During operation, it is important to keep the equipment stable and adjust parameters as needed based on environmental conditions.

[0004] When using traditional metal pipeline detectors, the transmitting coil and receiving antenna are usually designed with fixed dimensions. At the same time, high-power detectors are heavy due to their high-power transmitters, large transmitting coils, and robust housings. Prolonged operation can lead to worker fatigue, reduce work efficiency, and increase the difficulty and labor intensity of operation. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-power metal pipeline detector, which aims to improve the traditional metal pipeline detector. Due to its heavy weight, prolonged operation can lead to worker fatigue, reduced work efficiency, and increased operational difficulty and labor intensity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-power metal pipeline detector, comprising a handle, a display screen fixedly connected to one end of the handle, a fixed column fixedly connected to the outer wall of the display screen, an extension column slidably connected inside the fixed column, a large coil detector fixedly mounted at one end of the extension column, a power supply fixedly connected to one side of the outer wall of the extension column, an auxiliary wheel provided on the other side of the outer wall of the extension column, a locking block slidably connected inside the extension column, a driving component provided inside the extension column for driving the locking block to move, and a limiting component provided on the outer wall of the locking block for limiting the movement of the locking block;

[0009] Furthermore, a positioning component is provided on one side of the outer wall of the large coil detector. The positioning component is used to position the large coil detector. A snap-fit ​​screw is slidably connected inside the extension column. A slide rod is fixedly connected to one side of the outer wall of the snap-fit ​​screw. A spring is sleeved on the outer wall of the slide rod. A threaded sleeve is threadedly connected to the outer wall of the snap-fit ​​screw. A limit ring is fixedly connected to the outer wall of the snap-fit ​​screw.

[0010] Furthermore, the positioning component includes a connecting block, one side of the outer wall of the connecting block is fixedly connected to the outer wall of the large coil detector, the other side of the outer wall of the connecting block is slidably connected to the outer wall of the extension column, and a limit hole is formed inside the connecting block.

[0011] Furthermore, the outer wall of the snap-fit ​​block is slidably connected to the inside of the slide groove, and the snap-fit ​​block is used to fix the extended column after it has been moved.

[0012] Furthermore, the outer wall of the slide rod is slidably connected to the interior of the extension column, and the slide rod is used to guide the extension and retraction of the spring.

[0013] Furthermore, one end of the spring is fixedly connected to the inside of the extension post, and the other end of the spring is fixedly connected to the outer wall of the snap-fit ​​screw.

[0014] Furthermore, the outer wall of the limiting ring is slidably connected to the inside of the extension post, and the limiting ring is used to limit the movement of the locking screw.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the bidirectional screw is first driven to slide the locking block inside the extension column and the fixed column in conjunction with the bearing and the limiting block, thereby realizing the fixing and release of the extension column. Finally, the extension column is extended in conjunction with the sliding groove so that the auxiliary wheel can be set on the ground. Finally, the detection is carried out by the large coil detector in conjunction with the power supply and the display screen. At the same time, the large coil detector and the specially set power supply realize high-power detection, which solves the problem that the detector itself is heavy and long-term operation will cause fatigue of the staff, reduce work efficiency, and increase the difficulty of operation and labor intensity. When the staff operates standing up, they can adjust the length of the detector according to their height and operating habits, reduce the discomfort of bending over or stretching their body for a long time, reduce labor intensity, and improve work comfort.

Then, the sliding rod, the limiting ring and the spring are used to push the locking screw into the limiting hole. Finally, the threaded sleeve is used for further fixation to achieve the fixation and release of the connecting block and the large coil detector. This allows the coil to be removed for more intuitive inspection and repair when the coil part of the detector malfunctions. Attached Figure Description

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a high-power metal pipeline detector, including a handle 1, a display screen 19 fixedly connected to one end of the handle 1, a fixed column 2 fixedly connected to the outer wall of the display screen 19, an extension column 3 slidably connected inside the fixed column 2, the large coil detector 4 is extended by the fixed column 2 and the extension column 3, so as to facilitate the operation of workers of different heights. The large coil detector 4 is fixedly installed at one end of the extension column 3, and a power supply 5 is fixedly connected to one side of the outer wall of the extension column 3. The large coil detector 4 is used in conjunction with the specially designed power supply 5 to achieve the effect of high-power detection. An auxiliary wheel 6 is provided on the other side of the outer wall of the extension column 3. A locking block 9 is slidably connected inside the extension column 3. A driving component is provided inside the extension column 3 to drive the locking block 9 to move. A limit component is provided on the outer wall of the locking block 9 to limit the movement of the locking block 9.

[0027] The drive assembly includes a bearing 7, the outer wall of which is fixedly connected to the inside of the extension column 3. A bidirectional screw 8 is fixedly connected to the inner wall of the bearing 7. The outer wall of the bidirectional screw 8 is threadedly connected to the inside of the snap-fit ​​block 9. The drive bidirectional screw 8 is engaged with the threaded relationship between the bidirectional screw 8 and the snap-fit ​​block 9, so that the snap-fit ​​blocks 9 on both sides slide inside the fixed column 2 and the extension column 3 as the bidirectional screw 8 rotates. During this process, the limiting block 10 limits the movement. In addition, the bearing 7 stabilizes the rotation of the bidirectional screw 8. The limiting assembly includes a limiting block 10, the outer wall of which is fixedly connected to the outer wall of the snap-fit ​​block 9. The outer wall of the limiting block 10 is slidably connected to the outer wall of the extension column 3. A groove 11 is provided inside the fixed column 2. The movement of the snap-fit ​​block 9 is limited by the limiting block 10 to prevent the snap-fit ​​block 9 from leaving the inside of the extension column 3. The movement of the extension column 3 and the snap-fit ​​block 9 is limited by the groove 11. The snap-fit ​​block 9 can also be fixed by the groove 11.

[0028] Reference Figure 1 , Figure 4 and Figure 5A positioning component is provided on one side of the outer wall of the large coil detector 4. The positioning component is used to position the large coil detector 4. A snap-fit ​​screw 15 is slidably connected inside the extension column 3. A slide rod 13 is fixedly connected to one side of the outer wall of the snap-fit ​​screw 15. A spring 14 is sleeved on the outer wall of the slide rod 13. A threaded sleeve 17 is threadedly connected to the outer wall of the snap-fit ​​screw 15. The spring 14 pushes the snap-fit ​​screw 15 inside the extension column 3 and the connecting block 12. When the snap-fit ​​screw 15 has completely moved into the interior of the connecting block 12, the threaded sleeve 17 fixes the snap-fit ​​screw 15 to prevent the connecting block 12 from falling off. During disassembly, simply remove the threaded sleeve 17 and press the snap-fit ​​screw 15 back into the interior of the extension column 3. Then the connecting block 12 can be removed, realizing the disassembly and assembly of the connecting block 12 and the large coil detector 4. A limit ring 16 is fixedly connected to the outer wall of the snap-fit ​​screw 15. The positioning component includes the connecting block 12. One side of the outer wall of the connecting block 12 is fixedly connected to the outer wall of the large coil detector 4, and the other side of the outer wall of the connecting block 12 is slidably connected to the outer wall of the extension column 3. The connecting block 12 has a limiting hole 18 inside, which allows the locking screw 15 to slide into the connecting block 12. At the same time, the protrusion on the outer wall of the connecting block 12 can be used to position the connecting block 12 and the large coil detector 4. The outer wall of the locking block 9 is slidably connected to the inside of the slide groove 11. The locking block 9 is used to fix the extension column 3 after it has moved. The outer wall of the slide rod 13 is slidably connected to the inside of the extension column 3. The slide rod 13 is used to guide the extension and retraction of the spring 14. One end of the spring 14 is fixedly connected to the inside of the extension column 3, and the other end of the spring 14 is fixedly connected to the outer wall of the locking screw 15. The outer wall of the limiting ring 16 is slidably connected to the inside of the extension column 3. The limiting ring 16 is used to limit the movement of the locking screw 15.

[0029] Working principle: When a high-power metal pipeline detector is needed, the bearing 7 first drives the bidirectional screw 8 to rotate inside the extension column 3, thereby causing the locking blocks 9 on both sides to slide inside the fixed column 2 and the extension column 3. When the locking blocks 9 are completely moved inside the extension column 3, the extension column 3 can be pulled to slide inside the fixed column 2, thereby driving the large coil detector 4 to move and adjust the length. Finally, the auxiliary wheel 6 is used to facilitate the use of the detector.

[0030] Furthermore, the threaded sleeve 17 is rotated on the outer wall of the locking screw 15, thereby removing the threaded sleeve 17. Then, the locking screw 15 is pressed and slids inside the connecting block 12 and the extension post 3, while the spring 14 retracts. When the locking screw 15 has completely moved into the interior of the extension post 3, the connecting block 12 and the large coil detector 4 can be removed for inspection or replacement. During installation, simply reinsert the connecting block 12 into the outer wall of the extension post 3. At this time, the spring 14 pushes the locking screw 15 to move into the interior of the limiting hole 18, and finally it is fixed by the threaded sleeve 17, thus achieving the effect of convenient disassembly and assembly of the large coil detector 4.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
