Description

Technical Field

[0001] This invention relates to the field of pipeline detector technology, specifically an auxiliary device for underground pipeline detection. Background Technology

[0002] Pipeline detectors can quickly and accurately detect the location, direction, and depth of underground water pipes, metal pipes, cables, etc., without damaging the ground cover, as well as the location and size of damage points in the anti-corrosion layer of steel pipes. They are essential instruments for water companies, gas companies, railway communications, municipal construction, industrial and mining enterprises, and infrastructure units for the renovation, maintenance, and general survey of underground pipelines.

[0003] Typically, pipeline detectors require operators to hold and operate them, keeping the bottom of the instrument a certain distance from the ground and constantly moving it to detect pipelines via the display screen. However, holding the device for extended periods can cause hand pain and prevent prolonged use. Furthermore, the handle cannot be retracted when the instrument is not in use, taking up space. While the display screen shows the direction of underground pipelines, its limited size makes it difficult to display the pipeline routes clearly. Therefore, an auxiliary device for underground pipeline detection is needed to address these shortcomings. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an auxiliary device for underground pipeline detection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an underground pipeline detection auxiliary device, comprising a base, a support seat fixedly connected to the top of the base, and a display screen fixedly connected to the top of the support seat; a detector module fixedly connected to the bottom of the base; brackets movably connected to both sides of the base via rotating shafts, and a set of symmetrical rollers fixedly connected to the other end of each bracket; a limiting mechanism provided inside the base; a connecting mechanism provided inside the base; one end of the connecting mechanism movably connected to the limiting mechanism, and the other end of the connecting mechanism movably connected to the bracket; and auxiliary moving mechanisms provided on both sides of the support seat.

[0006] Furthermore, the limiting mechanism includes a long rod, an extension plate, a limiting rod, and an operating frame. The long rod, extension plate, and limiting rod are all symmetrically arranged. The long rod passes through the extension plate and is fixedly connected to the extension plate. The top ends of the limiting rods are fixedly connected to the bottom ends of the extension plates, and the top ends of the long rods are fixedly connected to the bottom ends of the operating frame.

[0007] Furthermore, the long rod, extension plate, limiting rod, and operating frame are all movably connected to the inside of the base. Both ends of the operating frame extend to the outside of the base, and the bottom end of the limiting rod extends to the outside of the base. A compression spring is sleeved on the outside of the long rod. The top end of the compression spring is fixedly connected to the bottom end of the extension plate, and the bottom end of the compression spring is fixedly connected to the inside of the base. A limiting hole is opened at the end of the bracket near the roller, and the limiting rod is adapted to the limiting hole.

[0008] Furthermore, the connecting mechanism includes a first synchronous pulley, a second synchronous pulley, a synchronous belt, and a rotating rod. A set of symmetrical first synchronous pulleys is fixedly connected to the end of the bracket away from the roller. A set of symmetrical rotating rods is movably connected inside the base through a rotating shaft. A set of symmetrical second synchronous pulleys is fixedly connected to the outer side of the rotating rods. A synchronous belt is sleeved on the outer side of the first and second synchronous pulleys, and the first synchronous pulley, the second synchronous pulley, and the synchronous belt constitute a belt drive structure.

[0009] Furthermore, an incomplete gear is fixedly connected to the middle section of the rotating rod, and a toothed block is fixedly connected to the bottom end of the long rod, with the toothed block meshing with the incomplete gear.

[0010] Furthermore, the auxiliary moving mechanism includes a movable block, a connecting rod, a cross block, and a control block. One end of the connecting rod is fixedly connected to the cross block, and the other end of the connecting rod is fixedly connected to the control block. The connecting rod passes through the movable block and is movably connected to the movable block. The control block is cross-shaped, and all movable blocks are movably connected to the side of the support base via a rotating shaft.

[0011] Furthermore, a return spring is sleeved on the outer side of the connecting rod, one end of the return spring is fixedly connected to the movable block, and the other end of the return spring is fixedly connected to the control block.

[0012] Furthermore, both sides of the support base are provided with cross holes, and the cross blocks are respectively adapted to the cross holes.

[0013] Furthermore, the detector module includes a detector body and a marker. The detector body is symmetrically arranged, and the marker is located on the opposite side of the detector body. The top of the detector body and the top of the marker are both fixedly connected to the bottom of the base.

[0014] Compared with existing technologies, this underground pipeline detection auxiliary device has the following advantages:

[0015] (1) The present invention uses a limiting mechanism to lift the operating frame upward, which drives the long rod to move upward inside the base. Under the action of the extension plate, the limiting rod moves upward, thereby separating the bottom end of the limiting rod from the limiting hole. Then the bracket is rotated outward until the roller contacts the ground, thereby removing the restriction on the bracket and making it convenient to store the bracket.

[0016] (2) The present invention uses a connecting mechanism to release the operating frame. Under the action of the compression spring, the long rod moves downward until the tooth block meshes with the incomplete gear, thereby keeping the bracket in a horizontal state and preventing the bracket from rotating during the movement of the base. This facilitates the storage and unfolding of the bracket, enabling staff to move the equipment for a long time, improving work efficiency and avoiding long-term equipment retrieval.

[0017] (3) The present invention uses an auxiliary moving mechanism to pull the control block outward, so that the connecting rod moves along the movable block. At the same time, the control block is rotated until the cross block is aligned with the cross hole. Then, under the action of the return spring, the cross block is inserted into the cross hole, thereby keeping the control block in a horizontal state. Then, the control block is used to push the entire device to move, which facilitates the control of the overall movement direction of the device and improves the controllability of the device.

[0018] (4) The present invention uses a detector module to detect the location of underground pipelines and uses a marker to scatter white marking lines on the ground, making it easier for staff to see the direction of underground pipelines more intuitively. Attached Figure Description

[0030] like Figure 1-7The underground pipeline detection auxiliary device shown includes a base 1, a support base 2 fixedly connected to the top of the base 1, and a display screen 3 fixedly connected to the top of the support base 2. A detector module 4 is fixedly connected to the bottom of the base 1. Both sides of the base 1 are movably connected to brackets 5 via rotating shafts, and a set of symmetrical rollers 6 are fixedly connected to the other end of each bracket 5. A limiting mechanism 7 is provided inside the base 1, and a connecting mechanism 8 is provided inside the base 1. One end of the connecting mechanism 8 is movably connected to the limiting mechanism 7, and the other end of the connecting mechanism 8 is movably connected to the brackets 5. Auxiliary moving mechanisms 9 are provided on both sides of the support base 2.

[0031] First, the limiting mechanism 7 is used to release the restriction on the bracket 5, causing it to flip outward until the bracket 5 is horizontal and the roller 6 contacts the ground. Then, the limiting mechanism 7 is used to keep the bracket 5 horizontal, which facilitates the storage and unfolding of the bracket 5, making it easier for staff to move the equipment for a long time, improving work efficiency and avoiding long-term equipment retrieval. In addition, the auxiliary moving mechanism 9 is used to facilitate the control of the overall movement direction of the equipment and improve the controllability of the equipment. Then, the entire equipment is pushed to move, and the detector module 4 at the bottom of the base 1 is used to detect the underground pipeline and display it on the display screen 3.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, the limiting mechanism 7 includes a long rod 701, an extension plate 702, a limiting rod 703, and an operating frame 704. The long rod 701, extension plate 702, and limiting rod 703 are symmetrically arranged. The long rod 701 passes through the extension plate 702 and is fixedly connected to it. The top ends of the limiting rods 703 are fixedly connected to the bottom ends of the extension plate 702. The top ends of the long rods 701 are all fixedly connected to the bottom ends of the operating frame 704. Both rod 703 and operating frame 704 are movably connected to the inside of base 1. Both ends of operating frame 704 extend to the outside of base 1. The bottom end of limiting rod 703 extends to the outside of base 1. Compression springs 10 are sleeved on the outside of long rod 701. The top end of compression spring 10 is fixedly connected to the bottom end of extension plate 702, and the bottom end of compression spring 10 is fixedly connected to the inside of base 1. Limiting hole 11 is opened at one end of bracket 5 near roller 6, and limiting rod 703 is adapted to limiting hole 11.

[0033] Lift the operating frame 704 upwards, causing the long rod 701 to move upwards inside the base 1. Under the action of the extension plate 702, the limiting rod 703 moves upwards, thereby separating the bottom end of the limiting rod 703 from the limiting hole 11. Then rotate the bracket 5 outwards until the roller 6 contacts the ground, thereby releasing the restriction on the bracket 5 and making it convenient to store the bracket 5.

[0034] like Figure 1 and Figure 3 As shown, the connecting mechanism 8 includes a first synchronous pulley 801, a second synchronous pulley 802, a synchronous belt 803, and a rotating rod 804. A set of symmetrical first synchronous pulleys 801 are fixedly connected to the end of the bracket 5 away from the roller 6. A set of symmetrical rotating rods 804 are movably connected inside the base 1 through a rotating shaft. A set of symmetrical second synchronous pulleys 802 are fixedly connected to the outer side of the rotating rod 804. The synchronous belt 803 is sleeved on the outer side of the first synchronous pulley 801 and the second synchronous pulley 802. The first synchronous pulley 801, the second synchronous pulley 802, and the synchronous belt 803 constitute a belt drive structure. An incomplete gear 12 is fixedly connected to the middle section of the rotating rod 804. A toothed block 13 is fixedly connected to the bottom end of the long rod 701, and the toothed block 13 meshes with the incomplete gear 12.

[0035] During the rotation of the bracket 5, the first synchronous wheel 801 rotates synchronously, and under the action of the synchronous belt 803, the second synchronous wheel 802 rotates synchronously, thereby causing the toothed part of the incomplete gear 12 to rotate directly below the tooth block 13. Then, the operating frame 704 is released, and under the action of the compression spring 10, the long rod 701 moves downward until the tooth block 13 meshes with the incomplete gear 12, thereby keeping the bracket 5 in a horizontal state and preventing the bracket 5 from rotating during the movement of the base 1. This facilitates the storage and unfolding of the bracket 5, making it easier for workers to move the equipment for a long time, improving work efficiency, and avoiding long-term equipment retrieval.

[0036] like Figure 1 , Figure 4 and Figure 6 As shown, the auxiliary moving mechanism 9 includes a movable block 901, a connecting rod 902, a cross block 903, and a control block 904. One end of the connecting rod 902 is fixedly connected to the cross block 903, and the other end of the connecting rod 902 is fixedly connected to the control block 904. The connecting rod 902 passes through the movable block 901 and is movably connected to the movable block 901. The control block 904 is cross-shaped. All movable blocks 901 are movably connected to the side of the support base 2 via a rotating shaft. A return spring 14 is sleeved on the outside of the connecting rod 902. One end of the return spring 14 is fixedly connected to the movable block 901, and the other end of the return spring 14 is fixedly connected to the control block 904. Cross holes 15 are opened on both sides of the support base 2, and the cross blocks 903 are respectively adapted to the cross holes 15.

[0037] Pull the control block 904 outward to move the connecting rod 902 along the movable block 901, and rotate the control block 904 until the cross block 903 is aligned with the cross hole 15. Then, under the action of the return spring 14, the cross block 903 is inserted into the cross hole 15, thereby keeping the control block 904 in a horizontal state. Then, use the control block 904 to push the entire device to move, which facilitates the control of the overall movement direction of the device and improves the controllability of the device.

[0038] like Figure 7 The detector module shown includes a detector body and a marker. The detector bodies are symmetrically arranged, and the markers are located on opposite sides of the detector bodies. The tops of both the detector bodies and the markers are fixedly connected to the bottom of the base. The detector body is electrically connected to the display screen.

[0039] The detector body is used to detect the location of underground pipelines, and markers are used to scatter white marking lines on the ground, thus making the route of the underground pipelines more intuitive.

[0040] Working principle: In use, firstly, lift the operating frame 704 upwards, causing the long rod 701 to move upwards inside the base 1. Under the action of the extension plate 702, the limiting rod 703 moves upwards, thus separating the bottom end of the limiting rod 703 from the limiting hole 11. Then, rotate the bracket 5 outwards until the roller 6 contacts the ground. During the rotation of the support, the first synchronous wheel 801 rotates synchronously. Under the action of the synchronous belt 803, the second synchronous wheel 802 rotates synchronously, thus rotating the toothed part of the incomplete gear 12 directly below the tooth block 13. Then, release the operating frame 704. Under the action of the compression spring 10, the long rod 701 moves downwards until the tooth block 13 meshes with the incomplete gear 12, thereby... Keep the support 5 horizontal to prevent the base 1 from rotating during movement. Then, pull the control block 904 outward to move the connecting rod 902 along the movable block 901. At the same time, rotate the control block 904 until the cross block 903 is aligned with the cross hole 15. Then, under the action of the return spring 14, the cross block 903 is inserted into the cross hole 15 to keep the control block 904 horizontal. Then, use the control block 904 to push the entire device to move. Use the detector module 4 at the bottom of the base 1 to detect the underground pipeline. Use the detector body to detect the location of the underground pipeline and use the marker to scatter white marking lines on the ground to more intuitively show the direction of the underground pipeline.
