Description

Technical Field

[0001] This utility model belongs to the field of geological exploration technology, specifically a borehole depth measuring device for geological exploration. Background Technology

[0002] In the field of geological exploration, borehole depth measurement is a crucial step in obtaining geological information. The accuracy of the measurement data directly affects the reliability of subsequent geological analysis, resource assessment, and engineering design. Whether it is mineral resource exploration, geological disaster early warning, or geological surveys in the early stages of engineering construction, drilling and precise measurement of borehole depth are essential to understand important information such as the distribution of underground rock strata and geological structural characteristics, providing a scientific basis for various decisions. Currently, most commercially available borehole depth measuring devices for geological exploration rely on a combination of a probe and a measuring rope to measure borehole depth. The basic working principle involves slowly lowering a probe with a detection function into the borehole via a measuring rope. When the probe contacts the bottom of the borehole or a specific geological interface, the depth is determined by reading the length of the measuring rope as it descends. However, in actual operation, these traditional measuring devices have significant technical flaws, the most prominent being the tendency for the measuring rope to accumulate after the probe has penetrated deep into the borehole. Specifically, when the probe moves into the hole under the action of gravity, the measuring rope needs to be lowered synchronously. After the probe falls to the bottom, some of the rope may fold, entangle, or accumulate inside the hole. This accumulation phenomenon will directly cause the actual length of the measuring rope to fall to be inconsistent with the actual distance the probe falls, thus causing deviations in the measurement data.

[0003] Therefore, a borehole depth measuring device for geological exploration is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a borehole depth measuring device for geological exploration. This device can straighten the measuring rope, preventing it from folding or piling up inside the borehole, which would cause the actual length of the measuring rope at the bottom to differ from the borehole depth, resulting in measurement data deviation. This improves the accuracy of borehole depth measurement and enhances the efficiency and reliability of geological exploration work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hole depth measuring device for geological exploration, comprising a support frame, a wire laying mechanism mounted on the surface of the support frame, and a probe mounted on one end of the wire laying mechanism; The surface of the support frame is equipped with a precision reading component, which includes a guide roller symmetrically rotatably connected to the surface of the support frame, an abutment plate symmetrically engaged in a through groove on the surface of the probe, and a threaded rod, a drive disc, a hinge seat, a push-pull plate, and a limit plate for driving. An auxiliary stabilizing component is installed on the surface of the abutment plate. The auxiliary stabilizing component includes a connecting plate symmetrically installed on the surface of the abutment plate, a guide rod installed on one side of the connecting plate, and a limiting disc and a guide cavity for limiting movement.

[0006] Preferably, the threaded rod is rotatably connected in a cavity inside the probe, the drive disc is threadedly connected to the surface of the threaded rod, the hinge seat is mounted on one side surface of the abutment plate, the two ends of the push-pull plate are respectively hinged to the drive disc and the hinge seat, the two limiting plates are symmetrically mounted on the surface of the drive disc, and the probe has a limiting groove inside that matches the limiting plate, and the limiting plate is slidably connected in this limiting groove.

[0007] Preferably, a limiting rod is slidably connected in the through hole on the surface of the limiting plate, and both ends of the limiting rod penetrate the limiting plate and are installed in the limiting groove inside the probe.

[0008] Preferably, a drive motor is installed inside the top of the probe, and the output end of the drive motor passes through the probe and is connected to one end of the threaded rod.

[0009] Preferably, the outer surface of the abutment plate is evenly provided with a plurality of friction protrusions.

[0010] Preferably, the two guide cavities are symmetrically formed inside the probe, the limiting disk is slidably connected inside the guide cavity, and one end of the guide rod passes through the guide cavity and is connected to the limiting disk.

[0011] Preferably, the surface of the probe is provided with a relief groove that is adapted to the connecting plate, and the connecting plate is slidably connected in this relief groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model incorporates a precision reading component. The guide roller provides real-time limiting and guiding for the measuring rope released by the wire feeding mechanism, preventing the measuring rope from shifting at the orifice. Simultaneously, the abutment plate, through the linkage of components such as the threaded rod and drive disc, abuts against the inner wall of the borehole, fixing the position of the probe and providing a stable foundation for subsequent straightening of the measuring rope. This solves the problem of reading deviation caused by the accumulation of measuring rope in traditional devices.

[0013] 2. This utility model, by setting up an auxiliary stabilizing component, provides precise guidance for the unfolding and resetting of the abutment plate through the cooperation of the connecting plate, guide rod and guide cavity, ensuring that the probe remains stable in the hole and can work normally even under complex geological conditions.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a hole depth measuring device for geological exploration, including a support frame 1, a wire laying mechanism 12 mounted on the surface of the support frame 1, and a probe 13 mounted on one end of the wire laying mechanism 12. The surface of the support frame 1 is equipped with a precision reading component 2. The precision reading component 2 includes a guide roller 21 that is symmetrically rotated and connected to the surface of the support frame 1, an abutment plate 22 that is symmetrically engaged with a through groove on the surface of the detector 13, a threaded rod 23 for driving, a drive disc 24, a hinge seat 25, a push-pull plate 26, and a limit plate 27. The threaded rod 23 is rotatably connected to the cavity inside the probe 13. The drive disk 24 is threadedly connected to the surface of the threaded rod 23. The hinge seat 25 is installed on one side surface of the abutment plate 22. The two ends of the push-pull plate 26 are respectively hinged to the drive disk 24 and the hinge seat 25. Two limiting plates 27 are symmetrically installed on the surface of the drive disk 24. The probe 13 has a limiting groove that matches the limiting plate 27. The limiting plate 27 is slidably connected in this limiting groove. The guide roller 21 can limit and guide the measuring rope released by the wire feeding mechanism 12 in real time, preventing the measuring rope from deviating at the orifice. At the same time, the abutment plate 22 can abut against the inner wall of the borehole through the linkage of the threaded rod 23, the drive disk 24 and other components, fixing the position of the probe 13 and providing a stable foundation for the subsequent straightening of the measuring rope, thus solving the problem of reading deviation caused by the accumulation of measuring rope in traditional devices.

[0018] A limiting rod 28 is slidably connected in the through hole opened on the surface of the limiting plate 27. Both ends of the limiting rod 28 pass through the limiting plate 27 and are installed in the limiting groove opened inside the probe 13. The limiting rod 28 passes through the limiting plate 27 and is fixed in the limiting groove of the probe 13, forming a limiting structure with the limiting plate 27. This prevents the drive disk 24 from shifting position during movement and improves the reliability of the measurement data.

[0019] A drive motor 29 is installed inside the top of the probe 13. The output end of the drive motor 29 passes through the probe 13 and is connected to one end of the threaded rod 23. The drive motor 29 can be remotely controlled (such as by connecting to a controller) to unfold and retract the abutment plate 22, thereby improving the efficiency and safety of deep hole measurement.

[0020] Multiple friction protrusions are evenly distributed on the outer side of the abutment plate 22. The friction protrusions can significantly increase the friction between the abutment plate 22 and the inner wall of the borehole. The friction protrusions can ensure that the position of the probe 13 is always fixed, and avoid the probe 13 from shifting due to the tension of the measuring rope.

[0021] An auxiliary stabilizing component 3 is installed on the surface of the abutment plate 22. The auxiliary stabilizing component 3 includes a connecting plate 31 symmetrically installed on the surface of the abutment plate 22, a guide rod 32 installed on one side of the connecting plate 31, a limiting disc 33 for limiting, and a guide cavity 34. Two guide cavities 34 are symmetrically opened inside the probe 13. The limiting disk 33 is slidably connected inside the guide cavity 34. One end of the guide rod 32 passes through the guide cavity 34 and is connected to the limiting disk 33. Through the cooperation of the connecting plate 31, the guide rod 32 and the guide cavity 34, precise guidance is provided for the unfolding and resetting of the abutment plate 22, ensuring that the probe 13 always maintains a stable state in the hole and can work normally even under complex geological conditions.

[0022] The surface of the probe 13 is provided with a relief groove that is adapted to the connecting plate 31. The connecting plate 31 is slidably connected in this relief groove. The relief groove provides sufficient space for the sliding of the connecting plate 31, ensuring that the connecting plate 31 unfolds and retracts with the abutment plate 22.

[0023] Among them, the support frame 1, the wire feeding mechanism 12, the detector 13 and the drive motor 29 are existing technologies, and their working principles are well-known technologies. The appropriate model is selected according to the actual use.

[0024] Working principle and process: The wire-laying mechanism 12 is activated, and the probe 13 is slowly lowered into the borehole via the measuring rope through the uniform wire-laying action of the wire-laying mechanism 12. During this process, the measuring rope is released from the wire-laying mechanism 12 and moves along the guide rollers 21 symmetrically arranged on the surface of the support frame 1. The guide rollers 21 limit and guide the measuring rope, initially preventing the measuring rope from deviating or accumulating at the borehole opening. During the lowering process, the position status of the probe 13 in the borehole is fed back in real time through the monitoring module (such as a pressure sensor or displacement sensor) built into the probe 13. If it encounters a borehole wall protrusion or rock cuttings, the wire-laying speed is adjusted in time to ensure that the probe 13 descends smoothly. When the probe 13 descends to near the bottom of the hole, the lowering action of the wire feeding mechanism 12 is stopped; the drive motor 29 inside the top of the probe 13 is started, and the output end of the drive motor 29 drives the threaded rod 23 to rotate in the cavity inside the probe 13. Since the drive disk 24 is threadedly connected to the surface of the threaded rod 23, and the drive disk 24 is slidably connected to the limiting groove inside the probe 13 through the limiting plate 27 (the limiting rod 28 further enhances the limiting stability), the rotation of the threaded rod 23 will drive the drive disk 24 to move along the axial direction of the threaded rod 23; during the movement of the drive disk 24, the push-pull plate 26 with hinged ends pushes the hinge seat 25, thereby driving the abutment plate 22 to unfold to the outside of the probe 13 until the friction protrusions on the surface of the abutment plate 22 are tightly attached to the inner wall of the borehole, thereby fixing the probe 13 in the hole; When the abutment plate 22 unfolds, the connecting plate 31 mounted on its surface will slide synchronously in the clearance groove on the surface of the probe 13; the guide rod 32 on one side of the connecting plate 31 drives the limiting plate 33 to slide in the guide cavity 34 inside the probe 13. The cooperation between the guide cavity 34 and the limiting plate 33 provides stable support for the unfolding of the abutment plate 22, preventing the abutment plate 22 from shifting due to uneven force, and further ensuring the stability of the probe 13 after it is fixed. After the probe 13 is completely fixed, the wire retraction function of the wire feeding mechanism 12 is activated to slowly and gradually retract the measuring rope. Since the probe 13 is fixed in position, the retraction process gradually straightens the measuring rope, which may have been folded or piled up inside the hole, until the rope is taut. At this point, the length of the lowered measuring rope is exactly the same as the actual distance the probe 13 descends. After the measuring rope is taut, the total length of the lowered measuring rope is accurately read using the length measuring module (such as an encoder) built into the wire feeding mechanism 12. This length is the actual drilling depth. If multiple measurements are required, the above steps can be repeated to ensure data consistency. After completing the hole depth measurement, the drive motor 29 is started in reverse to drive the threaded rod 23 to rotate in the opposite direction, so that the drive disc 24 is reset. Then, the push-pull plate 26 pulls the abutment plate 22 back into the through groove on the surface of the probe 13. Then, the wire release mechanism 12 is started to slowly retract the probe 13 and the measuring rope to the ground. Finally, all equipment is turned off, the device is cleaned and maintained, and the hole depth measurement work is completed.
