Description

Technical Field

[0001] This utility model belongs to the field of geological exploration technology, and in particular relates to a mineralization anomaly detection device. Background Technology

[0002] Geological exploration is an investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters.

[0003] In traditional electrical resistivity tomography (EDT) detection devices, poor contact between the electrode patch and the borehole wall leads to unstable measurement signals and poor data accuracy. In addition, detection devices with imaging functions share a power system with the imaging structure and the power supply structure, which generates electromagnetic interference between them during operation, seriously affecting the imaging quality and the reliability of the detection results.

[0004] In view of this, we propose a mineralization anomaly detection device. Utility Model Content

[0005] The purpose of this invention is to provide a mineralization anomaly detection device to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a mineralization anomaly detection device, including an inner protective tube, a battery compartment fixedly connected to the inner surface of the inner protective tube, an anti-collision shell fixedly connected to the lower end of the inner protective tube, a shooting structure installed on the inner surface of the anti-collision shell, and a heat insulation pad fixedly connected to the inner surface of the inner protective tube.

[0007] A linkage block is slidably connected to the inner surface of the heat insulation pad, a reset structure is installed on the inner surface of the heat insulation pad, an external push block is fixedly connected to the upper surface of the linkage block, and an electrode patch is fixedly connected to the outer arc surface of the external push block.

[0008] A limiting ring is fixedly connected to the inner surface of the inner protective tube. An extension frame is fixedly connected to the outer arc surface of the limiting ring. A rock nail is slidably connected to the inner surface of the extension frame. An electric telescopic rod is fixedly installed on the inner surface of the limiting ring. A soft push pile is fixedly connected to the lower end of the electric telescopic rod.

[0009] In this technical solution, the battery compartment is used to power the shooting structure separately. The outer surface of the battery compartment is fixedly connected by a rubber pad. The heat insulation pad is used to guide and limit the movement direction and distance of the linkage block. The main structure of the electrode patch is made of aluminum bronze. The outer arc surface of the electrode patch is provided with beryllium copper contacts. The electric telescopic rod has a built-in DC worm gear motor. The diameter of the extension rod inside the electric telescopic rod is smaller than the inner diameter of the limit ring. The lower edge of the soft push post is rounded.

[0010] In the above technical solution, the inner protective tube is further described as a circular tube, and the inner wall of the inner protective tube is provided with two rectangular grooves that extend to the outer arc surface of the inner protective tube. Electrode patches are slidably connected to the inner surface of the rectangular grooves.

[0011] In this technical solution, the main structure of the inner protective tube is made of stainless steel. The outer side of the inner protective tube has two slots. The upper slot is used to supply power to the electric telescopic rod and electrode patches, and the lower slot is used to charge the battery compartment.

[0012] In the above technical solution, a circular groove is provided at the center of the end of the anti-collision shell away from the inner protective tube, and ten cylindrical grooves are evenly distributed at the end of the anti-collision shell away from the inner protective tube.

[0013] In this technical solution, a thermally conductive silicone pad is provided inside the anti-collision shell, and a heating wire is provided on the inner surface of the anti-collision shell.

[0014] In the above technical solution, the shooting structure further includes a spherical camera and a fill light, with a shockproof shell fixedly connected to the outer surface of the spherical camera and a shockproof shell fixedly connected to the outer surface of the fill light.

[0015] In this technical solution, both the spherical camera and the fill light are connected to the anti-collision shell through shock-absorbing rubber, and the fill light is arranged around the spherical camera.

[0016] In the above technical solution, the reset structure further includes a reset spring and a guide rod. One end of the guide rod is fixedly connected to a heat insulation pad, and the end of the guide rod away from the heat insulation pad is fixedly connected to an inner protective tube. A linkage block is slidably connected to the outer circumferential surface of the guide rod, and a reset spring is fixedly connected to the outer surface of the linkage block. The end of the reset spring away from the linkage block is fixedly connected to an inner protective tube.

[0017] In this technical solution, the outer surface of the guide rod is polished after quenching, the diameter of the guide rod is slightly smaller than the inner diameter of the linkage block, and the return spring is a compression spring made of piano wire.

[0018] In the above technical solution, the push block is further defined as a trapezoidal block, with the outer surface of the push block near the electrode patch being an arc surface, the curvature of which is consistent with the curvature of the outer arc surface of the inner protective tube, and the outer surface of the push block away from the electrode patch being a slope.

[0021] In this technical solution, the limiting ring indirectly fixes the electric telescopic rod through the internal shock-absorbing pad, and the limiting ring is equipped with an LED strip.

[0022] The beneficial effects of this utility model are:

[0023] 1. This mineralization anomaly detection device uses an electric telescopic rod to drive a soft push pile downwards, which in turn pushes the inclined surfaces of the outer push blocks on both sides. This causes the outer push blocks to slide the electrode patch out of the inner protective tube and make the electrode patch fit against the inner wall of the borehole. This achieves the goal of making the electrode patch fit against the inner wall of the borehole as closely as possible, thus solving the problem of unstable measurement signals and poor data accuracy caused by poor contact between the electrode and the borehole.

[0024] 2. This mineralization anomaly detection device descends into the borehole through an inner protective tube. The spherical camera at its bottom, powered by a supplementary light and independently supplied by a battery compartment, records the scene inside the borehole. This achieves the goal of using two separate power systems for the imaging and power supply structures, solving the problem of electromagnetic interference between the imaging and power supply structures, which seriously affects the imaging quality and the reliability of the detection results.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0032] Example 1: This example provides a mineralization anomaly detection device, including an inner protective tube 1, a battery compartment 2 fixedly connected to the inner surface of the inner protective tube 1, an anti-collision shell 3 fixedly connected to the lower end of the inner protective tube 1, a shooting structure installed on the inner surface of the anti-collision shell 3, and a heat insulation pad 6 fixedly connected to the inner surface of the inner protective tube 1.

[0033] A linkage block 7 is slidably connected to the inner surface of the heat insulation pad 6, a reset structure is installed on the inner surface of the heat insulation pad 6, an outer push block 10 is fixedly connected to the upper surface of the linkage block 7, and an electrode patch 11 is fixedly connected to the outer arc surface of the outer push block 10.

[0034] A limiting ring 12 is fixedly connected to the inner surface of the inner protective tube 1. An extension frame 13 is fixedly connected to the outer arc surface of the limiting ring 12. A rock nail 14 is slidably connected to the inner surface of the extension frame 13. An electric telescopic rod 15 is fixedly installed on the inner surface of the limiting ring 12. A soft push pile 16 is fixedly connected to the lower end of the electric telescopic rod 15.

[0035] Among them, the battery compartment 2 is used to power the shooting structure separately. A rubber pad is fixedly connected to the outer surface of the battery compartment 2. The heat insulation pad 6 is used to guide and limit the movement direction and movement distance of the linkage block 7. The main structure of the electrode patch 11 is made of aluminum bronze. The outer arc surface of the electrode patch 11 is provided with beryllium copper contacts. The electric telescopic rod 15 has a built-in DC worm gear motor. The diameter of the extension rod inside the electric telescopic rod 15 is smaller than the inner diameter of the limiting ring 12. The lower edge of the soft push pile 16 is rounded.

[0036] The presence of the battery compartment 2 avoids the shooting structure and the electric telescopic rod 15 sharing the same power supply structure, thus avoiding the impact of voltage changes. The rubber pad on the outside of the battery compartment 2 is used for shock absorption, and the heat insulation pad 6 is also used to support the outer push block 10. The electrode patch 11 is used to fit against the inner wall of the slot, thereby better transmitting current. The electric telescopic rod 15 is used to drive the soft push pile 16 down at a constant speed. The rounded corners at the bottom of the soft push pile 16 prevent excessive scratching of the outer push block 10.

[0037] Example 2: This example provides a mineralization anomaly detection device. In addition to the technical solutions of the above examples, it also has the following technical features: the inner protective tube 1 is a circular tube, and the inner wall of the inner protective tube 1 is provided with two rectangular grooves that extend to the outer arc surface of the inner protective tube 1. Electrode patches 11 are slidably connected to the inner surface of the rectangular grooves.

[0038] The inner protective tube 1 is made of stainless steel. The inner protective tube 1 has two slots on its outside. The upper slot is used to supply power to the electric telescopic rod 15 and electrode patch 11, and the lower slot is used to charge the battery compartment 2.

[0039] The inner protective tube 1 is used to protect the internal structure and at the same time provide the necessary working environment for some parts of the structure.

[0040] Example 3: This example provides a mineralization anomaly detection device. In addition to the technical solutions of the above examples, it also has the following technical features: a circular groove is provided at the center of the end of the anti-collision shell 3 away from the inner protective tube 1, and ten cylindrical grooves are evenly distributed at the end of the anti-collision shell 3 away from the inner protective tube 1.

[0041] The anti-collision shell 3 has a thermally conductive silicone pad inside and a heating wire on its inner surface.

[0042] The thermally conductive silicone pad inside the anti-collision shell 3 is used to dissipate heat for the spherical camera 5 and the fill light 4. At the same time, the heating wire prevents the shell of the spherical camera 5 from fogging up due to excessive temperature difference between the structure and the groove under extreme conditions.

[0043] Example 4: This example provides a mineralization anomaly detection device. In addition to the technical solutions of the above examples, it also has the following technical features: the shooting structure includes a spherical camera 5 and a supplementary light 4. A shockproof shell 3 is fixedly connected to the outer surface of the spherical camera 5, and a shockproof shell 3 is fixedly connected to the outer surface of the supplementary light 4.

[0044] Among them, the spherical camera 5 and the fill light 4 are both connected to the anti-collision shell 3 through shock-absorbing rubber, and the fill light 4 is arranged around the spherical camera 5.

[0045] The spherical camera 5 and the fill light 4 are used to photograph and record the interior of the slot.

[0046] Example 5: This example provides a mineralization anomaly detection device. In addition to the technical solutions of the above examples, it also has the following technical features: the reset structure includes a reset spring 8 and a guide rod 9. One end of the guide rod 9 is fixedly connected to a heat insulation pad 6, and the end of the guide rod 9 away from the heat insulation pad 6 is fixedly connected to an inner protective tube 1. A linkage block 7 is slidably connected to the outer circumferential surface of the guide rod 9. The outer surface of the linkage block 7 is fixedly connected to a reset spring 8, and the end of the reset spring 8 away from the linkage block 7 is fixedly connected to an inner protective tube 1.

[0047] Among them, the outer surface of the guide rod 9 is polished after quenching, the diameter of the guide rod 9 is slightly smaller than the inner diameter of the linkage block 7, and the return spring 8 is a compression spring made of piano wire.

[0048] The guide rod 9 has a longer service life after being quenched and polished, and the return spring 8 also extends its own service life as much as possible.

[0049] Example 6: This example provides a mineralization anomaly detection device. In addition to the technical solutions of the above examples, it also has the following technical features: the push block 10 is a trapezoidal block, the outer surface of the push block 10 near the electrode patch 11 is an arc surface, the curvature of the arc surface is consistent with the curvature of the outer arc surface of the inner protective tube 1, and the outer surface of the push block 10 away from the electrode patch 11 is a slope.

[0050] The main structure of the push block 10 is surface-hardened medium carbon steel, and the inclined surface of the push block 10 is coated with polytetrafluoroethylene.

[0051] While ensuring its own strength, the coating on its inclined surface reduces friction with the soft push pile 16.

[0052] Example 7: This example provides a mineralization anomaly detection device. In addition to the technical solutions of the above examples, it also has the following technical features: the limiting ring 12 is an annular block, the outer diameter of the limiting ring 12 is the same as the inner diameter of the inner protective tube 1, the inner arc surface of the limiting ring 12 is provided with an annular groove, the inner surface of the annular groove is rotatably connected with a shock-absorbing pad, and the inner surface of the shock-absorbing pad is fixedly installed with an electric telescopic rod 15.

[0053] The limiting ring 12 indirectly fixes the electric telescopic rod 15 through the internal shock-absorbing pad, and the limiting ring 12 is equipped with a light strip on the outside.

[0054] The shock-absorbing pad of the limiting ring 12 reduces the friction between the electric telescopic rod 15 and the limiting ring 12 during operation, while the light strip is used to indicate the position of the structure.

[0055] Working principle: Multiple holes are drilled at the abnormal location, and then measuring electrodes are inserted near the holes. Then, multiple sets of inner protective tubes 1 are placed into the holes. When the inner protective tubes 1 are deeply inserted into the holes, the spherical camera 5 at the bottom of the inner protective tubes 5 records the scene inside the holes under the action of the supplementary light 4. When the insertion depth is sufficient, the outer extension frame 13 is stretched and the structure is fixed by the rock nail 14. Then, the electric telescopic rod 15 is activated, which drives the soft push pile 16 to descend, so that the soft push pile 16 pushes the inclined surfaces of the outer push blocks 10 on both sides, thereby causing the outer push blocks 10 to drive the electrode patch 11 to slide out of the inner protective tube 1 and make the electrode patch 11 fit with the inner wall of the hole, so that the rock layer is energized through the electrode patch 11. Then, the rock layer structure is preliminarily analyzed according to the measurement electrode readings.
