Description

Technical Field

[0001] This invention relates to the field of deep earth resource exploration and development technology, and in particular to a multifunctional integrated underground mine borehole sighting instrument. Background Technology

[0002] As mining depths continue to increase, underground geological conditions become increasingly complex, with fractured rock masses, developed fissures, and prominent potential geological hazards. Borehole inspection instruments have become important equipment for underground borehole exploration, rock mass quality testing, and geological hazard investigation in mines. They are used to directly obtain information about the rock mass structure, borehole wall morphology, and fissure development characteristics inside the borehole, providing key technical support for the safe and efficient mining of deep resources.

[0003] Existing downhole borehole sights suffer from numerous technical defects in practical applications, severely impacting detection efficiency, imaging quality, and operational safety. Regarding imaging assurance, when the probe advances within the borehole, debris such as coal dust, rock dust, and mud easily adheres to the lens surface, causing blurred or completely obstructed images. This necessitates frequent manual cleaning by removing the probe from the borehole, reducing the continuity of detection operations. Simultaneously, the significant temperature difference between the downhole borehole and the surface environment causes lens fogging and condensation after the probe enters the borehole, requiring prolonged periods of temperature adjustment or removal for cleaning, further extending the operation cycle and reducing efficiency. In terms of passage and propulsion performance, downhole borehole walls often contain obstacles such as local protrusions, rock accumulations, step-like steep slopes, and collapsed materials. Traditional probes lack obstacle-crossing structures, making them prone to jamming and obstruction during advancement. Often, drilling rigs are needed to re-penetrate the borehole to continue detection, making it difficult to ensure the continuity and integrity of the detection process. During deep hole detection, propulsion resistance increases significantly with depth, requiring substantial thrust, which can easily lead to deformation and breakage of the push rod, further impacting detection efficiency. In terms of safety protection, during the borehole exploration process, unstable rock blocks on the borehole wall are prone to falling due to the exploration disturbance. Falling rocks can directly rush down the borehole to the workers below, posing a serious safety hazard and making it difficult to guarantee the personal safety of the testing personnel down the well.

[0004] Therefore, there is an urgent need to design a multifunctional borehole inspection instrument that integrates self-cleaning, temperature control, obstacle-crossing, stable propulsion, and rockfall prevention functions to address the pain points of existing technologies and improve the comprehensive operational capabilities and safety level of borehole exploration in downholes. Summary of the Invention

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This invention discloses a multifunctional integrated underground borehole sighting device for mines.

[0028] Example 1: Reference Figures 1 to 4 A multi-functional integrated mine borehole sighting device mainly consists of a main unit, a multi-functional probe 1, a push rod 2, an integrated wire, an arc-shaped guide tube 3, and a rockfall prevention device 4. Each component is precisely assembled according to the working conditions of the borehole detection in the mine, realizing integrated operation of panoramic imaging, self-cleaning, temperature adjustment, obstacle crossing, stable propulsion, and rockfall prevention.

[0029] The arc-shaped guide tube 3 is made of arc-shaped steel pipe. One end of it is sealed and fixedly connected to the borehole opening pipe at the coal seam roof through a flange. The other end extends along the underground mine roadway towards the test platform 5. The curvature of the guide tube is matched and set according to the roadway height, borehole elevation angle, and test platform 5 height, providing a smooth guide channel for the push rod 2, multi-functional probe 1, and integrated wire, improving the situation where the push rod 2 may bend sharply, get stuck, experience uneven stress, or deform and break during the pushing process. The push rod 2 passes through the arc-shaped guide tube 3, and its top end is connected to the multi-functional probe 1. By pushing the push rod 2, the operator can smoothly push the multi-functional probe 1 along the arc-shaped guide tube 3 to the target detection position inside the borehole.

[0030] The multi-functional probe 1, as the core detection and execution component, includes a probe body 11, an axial lens 12, lateral lenses 13, a glass cover 14, a nozzle 15, a resistance wire 16, and a telescopic rod 17. The axial lens 12 is fixedly mounted at the center of the front end of the probe body 11, used to acquire images of the rock mass structure axially ahead of the borehole. Four lateral lenses 13 are fixedly mounted on the circumferential surface of the probe body 11 and evenly distributed circumferentially, forming a 360° panoramic image acquisition structure in conjunction with the axial lenses 12, completely acquiring image information of the entire borehole wall. The glass cover 14 is a transparent, integrated protective cover, enclosing the axial lenses 12 and lateral lenses 13, providing dust, scratch, and mud contamination protection while ensuring light transmission for image clarity. The nozzle 15 is fixedly mounted on the glass cover 14, with the water outlet facing the outer surface of the glass cover 14, used to spray cleaning fluid to remove coal dust, rock dust, mud, and other adhering substances from the surface of the glass cover 14. The resistance wire 16 is embedded inside the surface of the probe body 11, fitting tightly against it. When energized, it raises the overall temperature of the probe, eliminating fogging of the glass cover 14 caused by the temperature difference between the probe and the borehole. The telescopic rod 17 is installed inside the probe body 11 with a hidden embedded structure, evenly distributed around the circumference of the probe body 11. In the non-working state, it is completely retracted inside the probe body 11, without protruding from the probe's outer contour. In the working state, it can extend in multiple progressive stages, providing radial support, guidance, and attitude adjustment for the probe to overcome obstacles and advance stably within the borehole.

[0031] The main unit is placed on the test platform 5, located at the end of the arc-shaped guide tube 3 furthest from the borehole. The multi-functional probe 1 transmits signals and controls power to the main unit via integrated wires. The integrated wires run inside the arc-shaped guide tube 3 and contain independent pipelines, namely the camera power supply wire, heating wire, water spray pipeline, and telescopic rod 17 control wire. The axial lens 12 and the lateral lens 13 are electrically connected to the main unit via the camera power supply wire for image acquisition and transmission; the resistance wire 16 is electrically connected to the main unit via the heating wire for temperature control; the telescopic rod 17 is electrically connected to the main unit via the telescopic rod 17 control wire for telescopic drive; and the nozzle 15 is connected to the external water supply assembly via the water spray pipeline for a stable supply of cleaning fluid. The main unit has a built-in data processing module that can display real-time borehole temperature data and real-time images of the well wall, and automatically stitch together a panoramic cross-sectional view of the borehole wall.

[0032] A stone discharge port 31 is provided on the outer periphery of the bending inflection point in the middle of the arc-shaped conduit 3. The stone discharge port 31 is connected to the interior of the arc-shaped conduit 3, and its opening faces the area opposite to the test personnel. The anti-falling stone device 4 is detachably installed inside the arc-shaped conduit 3, at the bottom side of the stone discharge port 31, to intercept solid debris such as gravel and coal falling into the borehole and guide it to the stone discharge port 31 for discharge. The anti-falling stone device 4 consists of a semi-circular baffle I 41 and a baffle II. After the baffle I 41 and the baffle II are connected, their outer contours are adapted to the inner cross-section of the arc-shaped conduit 3, realizing full-section interception inside the conduit. A slot 43 is provided on the side wall of the baffle I 41 near the baffle II. A plug 44 adapted to the slot 43 is fixed on the side wall of the baffle II near the baffle I 41. Coaxial screw holes 45 are provided on the baffle I 41 and the plug 44. After the plug 44 is inserted into the slot 43 to complete the connection, it is rigidly fixed by screwing a screw into the screw hole 45. A retaining ring 46 and a bearing block 47 are fixedly installed on the inner wall of the arc-shaped conduit 3. Baffle I 41 is supported on the retaining ring 46, and baffle II is supported on the bearing block 47. The retaining ring 46 and the bearing block 47 provide stable support for the rockfall prevention device 4, ensuring structural stability during interception operations. A central hole 48 is provided in the middle of the side of baffle I 41 and baffle II that is close to each other, allowing only the push rod 2 and the integrated wire to pass through, thus blocking solid debris from passing through.

[0033] The push rod 2 is made of lightweight, high-strength fiberglass and is composed of multiple short rods spliced ​​together. The two short rods connected together form an angle, so that the multi-segment short rods are arranged in an arc shape to match the arc-shaped guide tube 3. Then the push rod 2 can be smoothly pushed into the interior along the inner wall of the arc-shaped guide rod, improving the smoothness of the push.

[0034] The method of using Embodiment 1 of this invention is as follows: One end of the arc-shaped guide tube 3 is sealed and fixed to the borehole opening pipe, and the other end extends to the test platform 5. A multi-segment short rod is spliced ​​to form an arc-shaped push rod 2, which is pushed forward from the bottom inlet of the arc-shaped guide tube 3. The multi-functional probe 1 is set at the front end of the push rod 2, and the probe is connected to the main unit through an integrated wire. Under the abutment and guidance of the arc-shaped guide tube 3, the push rod 2 undergoes elastic deformation and gradually moves towards the borehole. After the push rod 2 passes the installation position of the rockfall prevention device 4, the rockfall prevention device 4 is assembled with screws, and the push rod 2 and the integrated wire pass through the central hole 48 of the rockfall prevention device 4. After the equipment is assembled, it is powered on and debugged to confirm that the imaging, defogging, cleaning, and obstacle crossing functions are normal. During operation, the push rod 2 is pushed to send the probe into the borehole. The main unit collects and generates a panoramic image of the borehole wall in real time. When the lens is contaminated or fogged, the nozzle 15 and the resistance wire 16 are activated respectively to deal with it. When an obstacle is encountered, the telescopic rod 17 is controlled to overcome the obstacle. Rocks falling into the borehole are intercepted by the rockfall prevention device 4 and discharged through the rock discharge port 31, ensuring operational safety.

[0035] Example 2: Reference Figures 5 to 9 The difference between this embodiment and embodiment 1 is that the push rod 2 in this embodiment includes an arc-shaped rod segment 33 and a telescopic rod segment 17. A limiting conduit 32 is fixed to the inner wall of the arc-shaped conduit 3 near the center. The limiting conduit 32 and the arc-shaped conduit 3 are concentric arc structures. The inner diameter of the limiting conduit 32 is the same as the outer diameter of the arc-shaped rod segment 33. The arc-shaped rod segment 33 is slidably inserted into the arc-shaped conduit 3 along the limiting conduit 32. The limiting conduit 32 realizes the limiting guidance of the arc-shaped rod segment 33, avoiding the push rod 2 from deviating or shaking during the pushing process, making the push rod 2 push more smoothly and stably. The limiting conduit 32 extends from the bottom end of the arc-shaped conduit 3 to the anti-falling rock device 4, so that the subsequent multi-functional probe 1 and the telescopic rod segment 17 can be installed at the front end of the arc-shaped rod segment 33 to prevent interference. The outer wall of the arc-shaped rod segment 33 near the center has a recessed wire groove 331. The integrated wire is embedded in the wire groove 331, realizing the concealed layout of the integrated wire and further eliminating the problems of pipe entanglement and jamming. A side through hole 49 is opened on the side of the baffle I 41 away from the baffle II. The inner diameter of the side through hole 49 is adapted to the outer diameter of the arc-shaped rod segment 33. The arc-shaped rod segment 33 extends into the arc-shaped conduit 3 through the side through hole 49, optimizing the guiding path of the push rod 2 and making it less susceptible to impact from falling rocks.

[0036] The telescopic rod 17 segments are detachably connected to the top of the arc-shaped rod segment 33 via threads. The multi-functional probe 1 is installed at the end of the telescopic rod 17 segments away from the arc-shaped rod segment 33. The telescopic rod 17 segments include a fixed tube 351, a telescopic tube 352, and a corrugated airbag 353. The bottom end of the fixed tube 351 is threadedly connected to the bearing plate 354. The bottom end of the telescopic tube 352 is slidably inserted into the fixed tube 351. A movable cavity is formed between the fixed tube 351 and the telescopic tube 352. The corrugated airbag 353 is installed in the movable cavity, and the top end of the corrugated airbag 353 is bonded and fixed to the inner wall of the top of the telescopic tube 352. An air passage 34 is formed inside the arc-shaped rod segment 33 along its own arc length. One end of the air passage 34 is sealed and connected to the corrugated airbag 353 through a pipe, and the other end is connected to an external air supply device. The external air supply device supplies air into the air passage 34, driving the corrugated airbag 353 to expand, which in turn pushes the telescopic tube 352 to extend axially along the fixed tube 351, realizing adaptive adjustment of the length of the push rod 2. Compared with embodiment 1, it is more suitable for the detection needs of shallower drilling depths and improves the flexibility and stability of probe advancement. The top end of the telescopic tube 352 is fixedly connected to the support plate 354 by means of buckles or bolts. The multi-functional probe 1 is installed in the middle of the support plate 354, ensuring that the pushing direction of the multi-functional probe 1 is consistent with the drilling axis, and the problem of jamming is not likely to occur during the pushing process.

[0037] The method of use in Embodiment 2 of this invention is as follows: One end of the arc-shaped guide tube 3 is sealed and fixed to the borehole opening pipe, and the other end extends to the test platform 5. The arc-shaped rod segment 33 is pushed forward along the inner limiting guide tube 32 of the arc-shaped guide tube 3. After the arc-shaped rod segment 33 passes the installation position of the anti-falling rock device 4, the telescopic rod segment 17 and the multi-functional probe 1 are installed at the front end of the arc-shaped rod segment 33 through the rock discharge port 31. Then, the anti-falling rock device 4 is assembled with screws. After the equipment is assembled, it is powered on and debugged to confirm that the imaging, defogging, cleaning, and obstacle crossing functions are normal. During operation, the arc-shaped rod segment 33 is pushed to send the probe into the borehole opening position. The telescopic rod segment 17 is driven by the corrugated airbag 353 and the external air supply equipment to push the arc-shaped rod segment 33 forward in a directional manner. The length of the telescopic rod segment 17 is adjusted by the air supply to adapt to shallow hole detection. After the detection is completed, the pressure is released to reset the telescopic rod segment 17.
