Description

Technical Field

[0001] This utility model belongs to the technical field of metal pipeline detection equipment, specifically a metal pipeline detection device that is easy to assemble. Background Technology

[0002] Metal pipeline detection devices are core equipment in municipal construction, pipeline maintenance and other fields. They are used to detect the location, direction, burial depth and fault points of underground metal pipelines without excavation. The core is based on the principle of electromagnetic induction, supplemented by electromagnetic wave technology. It consists of a transmitter and a receiver. The transmitter applies a specific frequency signal to the pipeline through direct connection, induction and other methods. The receiver captures the magnetic field generated by the pipeline through an induction coil, thereby calculating the direction and path of the pipeline.

[0003] Existing metal pipeline detection devices have the following shortcomings: The receivers of existing metal pipeline detection devices need to be handheld during use. Prolonged handheld operation can easily cause arm pain and fatigue for operators, reducing detection efficiency. At the same time, it is difficult to maintain a stable height above the ground for a long time, which can easily lead to height deviation and directly affect the stability of signal reception.

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figures 1-8 As shown, this utility model provides a technical solution: A metal pipeline detection device that is easy to assemble includes a receiver body 1. A connecting plate 2 is fixedly connected to one side of the receiver body 1, and a pair of connecting pins 3 are fixedly connected to the bottom of the connecting plate 2. A housing 5 is provided on the side of the receiver body 1 near the connecting plate 2. A handle 20 is fixedly connected to one side of the housing 5 for easy removal and placement. A connecting groove 18 is provided on the top of the housing 5, which is adapted to the connecting plate 2. A pair of connecting holes 19 are provided at the bottom of the connecting groove 18, and each connecting hole 19 is adapted to a corresponding connecting pin 3. In use, the receiver body 1 rests against one side of the housing 5, the connecting plate 2 on one side of the receiver body 1 rests in the connecting groove 18 on the top of the housing 5, and the connecting pins 3 fall into the corresponding connecting holes 19.

[0016] The receiver body 1 has fixed rings 4 on both sides, and a pair of fixing components are provided on one side of the housing 5. The fixed rings 4 on both sides of the receiver body 1 are fixed by the fixing components, allowing the receiver body 1 and housing 5 to be quickly and securely assembled. The fixing components include a connecting block 8, which is fixedly connected to one side of the housing 5. A threaded rod 9 is threadedly connected to the connecting block 8. A second knob 10 is coaxially fixedly connected to one end of the threaded rod 9, and a fixing pin 11 is rotatably connected to the other end of the threaded rod 9. The fixing pin 11 is adapted to the fixing ring 4. The fixing pin 11 falls into the fixing ring 4. When the second knob 10 is rotated, the second knob 10 drives the threaded rod 9 to rotate, causing the fixing pin 11 to be pulled out from the fixing ring 4.

[0017] A worm gear 6 is rotatably connected to the housing 5. A first knob 7 is coaxially fixedly connected to the top of the worm gear 6. A pair of support components are provided inside the housing 5. The receiver body 1 contacts the ground and moves through the support components on the housing 5, avoiding height fluctuations when manually held and ensuring detection accuracy. The support components include a first rotating rod 12 and a second rotating rod 13. One end of the first rotating rod 12 and the second rotating rod 13 are rotatably connected to the housing 5. The first rotating rod 12 has a mounting groove, in which a worm wheel 14 is fixedly connected. The worm wheel 14 meshes with the worm gear 6. The other end of the first rotating rod 12 is rotatably connected to a mounting bracket 15. One end of the second rotating rod 13 is rotatably connected to the mounting bracket 15. A support wheel 16 is rotatably connected to one side of the mounting bracket 15. A pair of limiting grooves 17 are provided on the housing 5. The first rotating rod 12 and the second rotating rod 13 pass through the limiting grooves 17 and can move within the corresponding limiting grooves 17.

[0018] Specifically, the support wheel 16 contacts the ground, and the detection device moves via the support wheel 16. The worm gear 6 drives the worm wheel 14 to rotate, and the worm wheel 14 drives the first rotating rod 12 to rotate. The first rotating rod 12, the second rotating rod 13, and the mounting frame 15 form a parallelogram structure. A pair of rotating shafts are designed to pass through the first rotating rod 12 and the second rotating rod 13 respectively and be fixedly connected to them. Both ends of the pair of rotating shafts are rotatably connected to the housing 5. The worm wheel 14 is fixedly connected to the rotating shaft in the mounting groove of the first rotating rod 12. When the first rotating rod 12 rotates, it will move synchronously with the second rotating rod 13, driving the mounting frame 15 and the support wheel 16 on one side to move. The first rotating rod 12 and the second rotating rod 13 can move within the corresponding limiting grooves 17. The second rotating rod 13 has a receiving groove 21. When the first rotating rod 12 and the second rotating rod 13 rotate and are stored, part of the worm wheel 14 falls into the receiving groove 21 to prevent the worm wheel 14 from interfering with the second rotating rod 13.

[0019] Rotating the first knob 7 will drive the worm gear 6 to rotate, and the worm gear 6 will drive the support component to be flexibly adjusted. This not only adjusts the height of the receiver body 1 off the ground, but also allows the support component to be stored away when not in use, reducing the size of the device and making it easy to carry. When not in use, the fixing component can be pulled out from the fixing ring 4, and the connecting plate 2 on one side of the receiver body 1 can be separated from the connecting groove 18 on the top of the housing 5, allowing the receiver body 1 and the housing 5 to be quickly separated for easy storage or carrying. The working principle of this utility model is as follows: When in use, the receiver body 1 rests against one side of the housing 5, the connecting plate 2 on one side of the receiver body 1 rests in the connecting groove 18 on the top of the housing 5, the connecting pin 3 falls into the corresponding connecting hole 19, and the fixing pin 11 falls into the fixing ring 4, so that the receiver body 1 and the housing 5 are quickly and securely assembled. The support wheel 16 contacts the ground, and the detection device moves through the support wheel 16. Rotating the first knob 7 causes the worm gear 6 to rotate, which in turn drives the worm wheel 14 to rotate. The worm wheel 14 then drives the first rotating rod 12 to rotate. The first rotating rod 12, the second rotating rod 13, and the mounting bracket 15 form a parallelogram structure. Both the first rotating rod 12 and the second rotating rod 13 are rotatably connected to the housing 5. When the first rotating rod 12 rotates, it will move in sync with the second rotating rod 13, causing the mounting bracket 15 and the support wheel 16 on one side to move. This not only adjusts the height of the receiver body 1 off the ground, but also allows the support wheel 16 to be stored away when not in use. When not in use, turn the second knob 10. The second knob 10 drives the threaded rod 9 to rotate, so that the fixing pin 11 is pulled out from the fixing ring 4. The connecting plate 2 on one side of the receiver body 1 can be separated from the connecting groove 18 on the top of the housing 5, so that the receiver body 1 and the housing 5 can be quickly separated for easy storage or carrying.

[0020] The preferred embodiments of this patent have been described in detail above. However, this patent 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 this patent.
