Description

Technical Field

[0001] This application relates to the field of well detection technology, specifically a device for detecting the orientation of well nodes in underground pipeline networks. Background Technology

[0002] Detecting the orientation of manhole nodes in underground pipe networks (such as drainage, cable, and communication systems) is a crucial step in pipe network operation and maintenance and fault location. Existing technologies have developed various non-intrusive detection devices, one typical approach of which uses an insertable detection rod structure: the operator inserts the detection rod vertically into the manhole through a pre-drilled opening in the manhole cover, and a camera is integrated at the bottom of the rod to observe the distribution of pipe openings and node orientations on the manhole wall through image acquisition.

[0003] However, in the above-mentioned solutions, the opening of the manhole cover is usually located on the outer edge of the manhole cover, causing the insertion trajectory of the probe rod to deviate from the central axis of the manhole and descend close to the manhole wall. Some manhole inner walls have irregular obstacles such as cement repair protrusions, pipe flanges, or residual steel bars, which are very likely to collide with the probe rod. Since the camera is inserted close to the manhole wall, the protrusions on the inner wall directly block the lens's lateral field of view, making it difficult to fully capture the position and direction information of the opposite pipe opening, reducing the image clarity and reliability of the detection, and resulting in poor detection effect. Utility Model Content

[0004] In view of the problem of poor detection effect in the existing technology, this utility model provides a device for detecting the orientation of underground pipeline well nodes.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides a device for detecting the orientation of underground pipeline well nodes, characterized in that it includes:

[0007] A fixed rod is provided, with an adjusting rod rotatably mounted at the bottom of the fixed rod, a detection rod rotatably mounted at the bottom of the adjusting rod, and a camera fixedly mounted at the bottom of the detection rod;

[0008] The fixed rod has a sliding groove, and a folding plate is slidably arranged in the sliding groove. A rack is fixedly arranged at the bottom of the folding plate. A gear rod that meshes with the rack is fixedly arranged at the top of the adjusting rod. A screw is rotatably arranged in the sliding groove. The folding plate is fitted onto the screw. The fixed rod has a mounting cavity, and a motor is fixedly arranged in the mounting cavity. The output shaft of the motor is connected to one end of the screw.

[0009] Preferably, the fixing rod has a through hole above the mounting cavity, and a limiting rod is horizontally inserted into the through hole. When the fixing rod, adjusting rod and detection rod are inserted into the well through the opening hole of the well cover, the limiting rod horizontally set in the through hole can abut against the top of the well cover, thereby limiting the fixing rod, adjusting rod and detection rod, avoiding the need for the operator to continuously hold the fixing rod during detection, and making the operation convenient.

[0010] Preferably, a second screw is provided in the through hole, and the second screw is rotatably connected to the fixed rod. A limiting rod is fitted onto the second screw. An end cap is rotatably provided on the top of the fixed rod, and one end of the end cap is fixedly connected to one end of the second screw. When adjusting the height of the limiting rod, the operator rotates the end cap on the top of the fixed rod. The end cap drives the second screw in the through hole to rotate. Through the threaded engagement between the second screw and the limiting rod, the limiting rod is driven to rise and fall vertically along the through hole, thereby adjusting the insertion depth of the fixed rod and improving its applicability.

[0011] Preferably, it also includes a base, which is located below the limiting rod. The top of the base abuts against the bottom of the limiting rod. When the limiting rod in the through hole abuts against the top of the manhole cover, the base is placed on the manhole cover, and then the bottom of the limiting rod abuts against the top of the base, which facilitates the rotation and adjustment of the limiting rod.

[0012] Preferably, the base is provided with an annular groove, and sliders that fit into the annular groove are fixedly provided at both ends of the limiting rod. The sliders at both ends of the limiting rod are embedded in the annular groove of the base. The limiting rod is limited by the sliders and the annular groove to ensure the stability of the limiting rod abutting against the base.

[0013] Preferably, the top outer edge of the base is provided with scale lines along the circumference. When rotating the fixed rod to avoid the protrusions of the well wall, the fixed rod drives the two ends of the limiting rod to slide along the annular groove on the base. After the fixed rod is rotated horizontally to a suitable angle according to the scale lines, the adjustment rod is rotated. This facilitates the camera to take pictures of different points in the well when taking pictures, avoids some obstacles in the well from blocking the shooting point, and ensures the integrity of the shooting.

[0014] Preferably, the base has multiple sets of support rods spaced circumferentially at its bottom, with the top of the support rods threaded into the base. When the ground around the manhole cover is uneven, the height of the corresponding support rod can be adjusted by rotating the corresponding support rod at the bottom of the base, thereby adjusting the base to a horizontal state, which facilitates the insertion of the fixing rod and the detection rod.

[0015] The advantages of adopting the above technical solution are:

[0016] This invention includes a fixed rod, with an adjusting rod rotatably mounted at its bottom. A detection rod is rotatably mounted at the bottom of the adjusting rod, and a camera is fixedly mounted at the bottom of the detection rod. The fixed rod has a sliding groove, within which a folding plate slides. A rack is fixedly mounted at the bottom of the folding plate, and a gear rod meshing with the rack is fixedly mounted at the top of the adjusting rod. A screw is rotatably mounted within the sliding groove, and the folding plate is fitted onto the screw. The fixed rod has a mounting cavity, within which a motor is fixedly mounted. The motor's output shaft is connected to one end of the screw. During detection, if a protrusion exists on the inner wall of the wellbore, rotating the adjusting rod causes it to move the detection rod away from the protrusion, thus effectively detecting the inside of the wellbore and improving the detection effect.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] like Figure 1-5 As shown in the figure, this utility model embodiment discloses an underground pipeline well node orientation detection device, including a fixed rod 1, an adjusting rod 2 rotatably disposed at the bottom of the fixed rod 1, a detection rod 3 rotatably disposed at the bottom of the adjusting rod 2, and a camera 4 fixedly disposed at the bottom of the detection rod 3;

[0026] The fixed rod 1 is provided with a sliding groove 101, and a folding plate 6 is slidably arranged in the sliding groove 101. A rack 601 is fixedly arranged at the bottom of the folding plate 6. A gear rod 201 that meshes with the rack 601 is fixedly arranged at the top of the adjusting rod 2. A screw 701 is rotatably arranged in the sliding groove 101. The folding plate 6 is fitted onto the screw 701. The fixed rod 1 is provided with a mounting cavity, and a motor 7 is fixedly arranged in the mounting cavity. The output shaft of the motor 7 is connected to one end of the screw 701 for transmission.

[0027] In at least one embodiment, the fixing rod 1 has a through hole 102 above the mounting cavity, and a limiting rod 5 is horizontally inserted into the through hole 102. When the fixing rod 1, adjusting rod 2 and detection rod 3 are inserted into the well through the opening of the well cover, the limiting rod 5 horizontally set in the through hole 102 can abut against the top of the well cover, thereby limiting the fixing rod 1, adjusting rod 2 and detection rod 3, avoiding the need for the operator to continuously hold the fixing rod 1 during detection, making the operation convenient.

[0028] In at least one embodiment, a second screw 8 is provided in the through hole 102, and the second screw 8 is rotatably connected to the fixed rod 1. The limiting rod 5 is fitted onto the second screw 8. An end cap 801 is rotatably provided on the top of the fixed rod 1. One end of the end cap 801 is fixedly connected to one end of the second screw 8. When adjusting the height of the limiting rod 5, the operator rotates the end cap 801 on the top of the fixed rod 1. The end cap 801 drives the second screw 8 in the through hole 102 to rotate. Through the threaded engagement between the second screw 8 and the limiting rod 5, the limiting rod 5 is driven to rise and fall vertically along the through hole 102, thereby adjusting the insertion depth of the fixed rod 1 and improving its applicability.

[0029] In at least one embodiment, a base 9 is also included. The base 9 is located below the limiting rod 5, and the top of the base 9 abuts against the bottom of the limiting rod 5. When the limiting rod 5 in the through hole 102 abuts against the top of the manhole cover, the base 9 is placed on the manhole cover, and then the bottom of the limiting rod 5 abuts against the top of the base 9, so as to facilitate the rotation and adjustment of the limiting rod 5.

[0030] In at least one embodiment, the base 9 is provided with an annular groove 901, and sliders that are fitted to the annular groove 901 are fixedly provided at both ends of the limiting rod 5. The sliders at both ends of the limiting rod 5 are embedded in the annular groove 901 of the base 9. The limiting rod 5 is limited by the sliders and the annular groove 901 to ensure the stability of the limiting rod 5 abutting against the base 9.

[0031] In at least one embodiment, the top outer edge of the base 9 is provided with scale lines along the circumference. When rotating the fixed rod 1 to avoid the protrusions of the well wall, the fixed rod 1 drives the two ends of the limiting rod 5 to slide along the annular groove 901 on the base 9. After rotating the fixed rod 1 horizontally to a suitable angle according to the scale lines, the adjustment rod 2 is rotated. This facilitates the camera 4 to take pictures of different points in the well when taking pictures, avoids some obstacles in the well from blocking the shooting point, and ensures the integrity of the shooting.

[0032] In at least one embodiment, multiple sets of support rods 902 are arranged circumferentially at the bottom of the base 9. The top of the support rods 902 is threaded into the base 9. When the ground around the manhole cover is uneven, the height of the corresponding support rod 902 at the bottom of the base 9 is adjusted by rotating the corresponding support rod 902, thereby adjusting the base 9 to a horizontal state, which facilitates the insertion of the fixing rod 1 and the detection rod 3.

[0033] In at least one embodiment, a battery pack and a switch module are provided on the fixed rod 1. The motor 7 is electrically connected to the battery pack and the switch module through wires. The operator adjusts the working state of the motor 7 through the switch module. The camera 4 is a wireless camera and is wirelessly connected to an external image display device.

[0034] When conducting surveying operations on the alignment of underground pipeline shaft nodes, workers insert the adjusting rod 2 and the detection rod 3 at the bottom of the fixed rod 1 into the shaft through the opening of the manhole cover. The camera 4 at the bottom of the detection rod 3 captures images of the shaft below. The camera 4 integrates lighting equipment to ensure clear imaging of the shaft. The camera 4 is connected to an external image display device, allowing workers to observe and record the alignment of nodes within the shaft. When the detection rod 3 and adjusting rod 2 are inserted below the manhole cover, and a protrusion in the shaft wall below the camera 4 affects image acquisition, workers rotate the fixed rod 1, causing the adjusting rod 2 to rotate along the side away from the shaft wall as the fixed rod 1 rotates. Then, the motor 7 inside the installation cavity is activated. The motor 7 drives the screw 701 inside the slide groove 101 to rotate. The screw 701 and the folding plate 6 are threaded together, causing the folding plate 6 to move vertically up and down along the slide groove 101. When the folding plate 6 descends, the gear 601 at the bottom engages with the gear rod 201 on the adjusting rod 2, causing the gear rod 201 to drive the adjusting rod 2 to rotate. As the adjusting rod 2 moves the detection rod 3 away from the protrusion on the well wall, the detection rod 3, which is rotated at the bottom of the adjusting rod 2, remains vertical under its own weight. When the detection rod 3 moves away from the protrusion to a suitable position, the camera 4 at the bottom of the detection rod 3 can effectively capture images of the well below, facilitating the observation and recording of nodes within the well by the staff. This convenient operation improves the detection effect. After the detection is completed, the adjusting rod 2 and the detection rod 3 are restored to a vertical position and then removed through the opening of the well cover.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
