Description

Technical Field

[0001] The utility model provides a locator, belonging to the technical field of underground pipeline detection equipment, and particularly relates to an underground pipeline detection and locator. Background Art

[0002] An underground pipeline detection and locator is a high-precision instrument specifically designed to detect and locate various pipelines, cables, and pipes buried underground. It determines the depth, position, and direction of underground pipelines by emitting signals at specific frequencies and receiving the reflected signals. It is usually equipped with multiple detection modes to adapt to different detection environments and targets, such as charged or uncharged pipelines, metal or non-metal pipelines, and precise positioning in complex urban environments. These devices are crucial for urban planning, construction, pipeline maintenance, and repair, as they can effectively avoid damaging underground pipelines during excavation or construction, ensuring construction safety and the integrity of pipelines.

[0003] In existing underground pipeline detection practices, the detection equipment is usually manually carried by operators and moved on the site to locate and map underground pipelines. However, this operation method is easily affected by the slight movement and unstable movement of the operator's hand, thereby introducing additional errors and reducing the accuracy and reliability of the detection operation. In addition, due to the frequent movement of the detection equipment during manual operation, its physical structure is more vulnerable to accidental collisions and drops, increasing the risk of equipment damage. This not only affects the service life of the equipment but may also lead to inaccurate detection data, thereby affecting subsequent geographical information mapping and pipeline management decisions. Summary of the Utility Model

[0004] Embodiments of this application are to make up for the deficiencies of the prior art. By providing an underground pipeline detection and locator, the problems of jitter interference and accuracy loss caused by manual operation by operators are solved, the stability and durability of the equipment are enhanced, and the accuracy and operation efficiency of detection are improved.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: An underground pipeline detection and locator includes a detector body. A fixing structure is sleeved below the detector body. The fixing structure includes an outer frame sleeved outside the detector body. A locking member closely attached to the outside of the detector body is movably connected inside the outer frame. Both sides of the outer frame are connected by connecting rods to rollers disposed below itself.

[0006] Preferably: Symmetrically distributed T-shaped first limiting grooves are provided on the outer frame. Second limiting grooves corresponding to the outer frame and having the same shape as the first limiting grooves are provided inside the connecting rods.

[0007] Preferably, limiting rods corresponding to the first limiting groove and the second limiting groove are respectively provided on both sides of the locking member and on both sides of the outer frame.

[0008] Preferably, a fixing member connected to the locking member is fixedly connected to one end of the limiting rod away from the outer frame, and a bolt structure penetrating through itself is provided on the fixing member.

[0009] Preferably, both the outer frame and the locking member are a pair of symmetrically distributed workpieces.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] In the present utility model, by providing a fixing structure sleeved outside the detector body, the fixing structure plays a protective role for the detector body by means of the outer frame. At the same time, the outer frame and the locking member that are movably connected to each other allow the detector body to freely rotate in both horizontal and vertical directions. The direction of the detector body can be easily adjusted through the handle on the detector body, and then it can be pushed forward by means of the rollers. In this process, the detector body can maintain a stable relative movement with the detection area to ensure the detection accuracy; in the normal state, the detector body will drive the locking member to rotate relative to the outer frame under the action of its own gravity, and the outer frame rotates relative to the connecting rod, so as to maintain a vertically hanging state.

[0012] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs; the terms used in the description of the present invention in this specification are only for the purpose of describing specific implementation manners and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] As Figure 1 and Figure 2 shown, an underground pipeline detection and positioning instrument includes a detector body 1, and a fixed structure 2 is sleeved below the detector body 1. The fixed structure 2 includes a pair of symmetrically distributed outer frames 21 sleeved outside the detector body 1. Symmetrically distributed T-shaped first limiting grooves 23 are provided on the outer frame 21. A second limiting groove corresponding to the outer frame 21 and having the same shape as the first limiting groove 23 is provided inside the connecting rod 11. A pair of corresponding locking members 22 closely attached to the outside of the detector body 1 are movably connected inside the outer frame 21. Both sides of the outer frame 21 are connected by a connecting rod 11 to a roller 12 placed below itself

[0026] In this implementation scheme, in the design of the detection device, an integrated fixing mechanism is adopted. This mechanism realizes physical protection of the main body by configuring a protective fixing structure 2 around the main body 1 of the detection device. The fixing structure 2 is supported by its attached external frame 21 to ensure the stability of the device during operation. In addition, an active connection method is adopted between the external frame 21 and the locking member 22, enabling the main body 1 of the detection device to rotate freely in multiple axes on the horizontal and vertical planes, thus adapting to different detection angle requirements. For ease of operation, the main body 1 of the detection device is equipped with an operation handle, allowing the user to easily adjust the direction of the device through the handle. During the advancement process, the main body 1 of the device moves smoothly through the rollers 12 at its bottom, which helps to maintain a constant contact between the device and the detection area, thus ensuring the accuracy of detection. In the normal operation state, the self-weight of the main body 1 of the detection device will cause the locking member 22 to rotate relative to the external frame 21, and then drive the external frame 21 to rotate correspondingly relative to the connecting rod 11 to maintain the drooping posture of the device in the vertical direction, which helps to ensure the stability and operational convenience of the device in different detection environments.

[0027] As Figure 3 and Figure 4 shown, on both sides of the locking member 22 and on both sides of the external frame 21, there are limiting rods 24 corresponding to the first limiting groove 23 and the second limiting groove respectively. One end of the limiting rod 24 fixedly connected to the locking member 22, which is far from the external frame 21, is fixedly connected to a fixing member 25 connected to the locking member 22. The fixing member 25 is provided with a bolt structure 26 passing through itself.

[0028] In this implementation scheme, the locking member 22 rotates inside the first limiting groove 23 by means of the limiting rod 24, driving the detector body 1 to rotate. The external frame 21 rotates inside the second limiting groove by means of the limiting rod 24. The spatial positions of the first limiting groove 23 and the second limiting groove are perpendicular.

[0029] In use, first, take out the underground pipeline detector and locator from the packaging and check whether all components are complete, including the detector body 1, the fixing structure 2, the outer frame 21, the locking part 22, the connecting rod 11, the roller 12, as well as the limiting rod 24 and the fixing part 25; ensure that the detector body 1 has been correctly installed in the fixing structure 2, confirm that the outer frame 21 is symmetrically sleeved outside the detector body 1, and the T-shaped first limiting groove 23 is in place, connect the locking part 22 movably to the inner side of the outer frame 21 to ensure that they can rotate freely, check whether the connecting rod 11 is correctly connected to both sides of the outer frame 21, and ensure that the roller 12 has been installed below the connecting rod 11; place the device in the area to be detected, ensure that the detector body 1 is in good contact with the ground, adjust the direction of the device through the operating handle to align it with the detection starting point; turn on the power of the device, and if the device needs preheating or calibration, operate it according to the device instruction manual; push the device with the operating handle to make the roller 12 contact the ground and start moving forward, and adjust the angle and direction of the device through the movable connection between the locking part 22 and the outer frame 21, as well as the rotation of the limiting rod 24 in the first limiting groove 23 and the second limiting groove to adapt to different detection paths and angle requirements; during the detection process, record the position, depth and other relevant information of the pipeline, and these data can be recorded through the built-in recording system of the device or manually; during the detection process, if it is necessary to change the detection direction or adjust the detection depth, it can be achieved by rotating the locking part 22 and the outer frame 21. After the detection is completed, stop the movement of the device and turn off the power, sort out and analyze the detected data to determine the accurate position and layout of the underground pipeline. After the detection is completed, carry out necessary cleaning and maintenance on the device to ensure that the device can work normally during the next use.
