Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mine measurement, more particularly, it relates to a real-time depth feedback multi-aperture borehole peeping fixing device. BACKGROUND

[0002] The borehole peeping instrument is the core equipment for engineering exploration and safety monitoring in coal mine, and undertakes the important task of borehole quality evaluation and geological information collection. Through high-resolution imaging technology, it can obtain real-time internal structure of the borehole, fracture development characteristics of the hole wall, distribution of rock layer interface and gas enrichment area and other key information, and provide visual data basis for optimization of roadway support parameters, early warning of disaster hidden dangers (such as coal and gas outburst and water inrush accident) and identification of concealed geological conditions. The application of the technology significantly improves the transparency and safety of underground operation in coal mine, and is an indispensable detection means in intelligent mine construction.

[0003] At present, the mainstream borehole peeping instrument mainly depends on the structure design of rigid or semi-rigid camera, which can realize basic imaging function under ideal working conditions with complete hole wall and small deformation. However, the underground environment of coal mine is complex, and the borehole is affected by many factors such as geological structure movement, superimposed mining stress and mechanical construction disturbance, so the hole wall often presents dynamic non-uniform deformation characteristics, such as local collapse, radial extrusion shrinkage or rock layer dislocation. Such deformation directly leads to unbalanced stress on the contact surface between the peeping instrument probe and the hole wall, causing the probe to vibrate violently, deviate in posture and even be stuck, which seriously interferes with the stability of imaging. At the same time, it is difficult to maintain the focusing accuracy and the direction of the probe in the process of dynamic deformation of the hole wall, causing image blur, data fault and failure to take pictures, which greatly limits the applicability and reliability of the equipment under complex geological conditions. SUMMARY

[0004] The present application discloses a real-time depth feedback multi-aperture borehole peeping fixing device, which solves the technical problem of difficult to take pictures caused by the dynamic non-uniform deformation characteristics of the hole wall in the background technology.

[0005] The present application discloses a real-time depth feedback multi-aperture borehole peeping fixing device, which includes a circular plate, the surface of the circular plate is provided with an extension line, the end of the extension line is provided with a peeping instrument probe, a synchronous mechanism, the synchronous mechanism includes a carrier arranged on the surface of the peeping instrument probe, the carrier is internally provided with a hollow tooth, a plurality of synchronous pieces are arranged, which are circumferentially distributed around the carrier and assembled in the carrier, a plurality of co-sites are arranged, which are axially arranged in the carrier based on the carrier, the execution distance of the synchronous piece is corrected in real time, a pushing mechanism is arranged on the surface of the carrier, the effective matching length of which is matched with the working length of the carrier, and the pushing mechanism provides continuous forward thrust when the carrier moves.

[0006] As a preferred scheme of the real-time depth feedback multi-aperture drilling peeping fixing device, the synchronizer comprises an extension leg arranged inside the carrier, a straight block is fixedly connected to the end of the extension leg, and a roller is rotatably connected through the straight block.

[0007] As a preferred scheme of the real-time depth feedback multi-aperture drilling peeping fixing device, the synchronizer comprises a synchronizing plate arranged inside the carrier, an active notch is arranged inside the synchronizing plate, a rack is arranged inside the active notch, and an adapter block is arranged on the surface of the synchronizing plate.

[0008] As a preferred scheme of the real-time depth feedback multi-aperture drilling peeping fixing device, a plurality of the adapter blocks and a plurality of the extension legs are in one-to-one correspondence and are fixedly connected.

[0009] As a preferred scheme of the real-time depth feedback multi-aperture drilling peeping fixing device, a telescopic rod is arranged on the inner wall of the carrier, a spring I is sleeved on the surface of the telescopic rod, and a plurality of groups of light supplement lamps are arranged on the surface of the carrier, close to the peeping instrument probe.

[0010] As a preferred scheme of the real-time depth feedback multi-aperture drilling peeping fixing device, the end of the telescopic rod is fixedly connected to one of the synchronizing plates.

[0011] As a preferred scheme of the real-time depth feedback multi-aperture drilling peeping fixing device, a plurality of the synchronizing plates are arranged in a stepped manner on the surface of the hollow teeth, and the rack is engaged with the hollow teeth.

[0014] As a preferred scheme of the real-time depth feedback multi-aperture drilling peeping fixing device, a plurality of the extension legs and the rollers are always in the same horizontal line in the working state.

[0015] The beneficial effects of the present invention are: through the setting of the propulsion mechanism, for the complex working conditions of the dynamically deformed hole wall, when the peephole probe is inside the dynamically deformed hole wall, the circular plate limit is coordinated with the rotation of the spring wire to generate a forward force, and at the same time, the multi-degree-of-freedom flexible structure is used to adapt to the deformation of the hole wall, thereby realizing the adaptive propulsion and stable imaging of the peephole probe. When the peephole probe is stuck, the operation can be reversed to make the peephole probe actively retreat.

[0016] The beneficial effect of the present invention is that: through the setting of the synchronization mechanism, when one of the isotropic plates is forced to retract inward, the other isotropic plates are synchronously moved to the same stroke through the hollow teeth, so that the peephole probe can perform dynamic self-aligning function in the irregular hole wall when moving forward to take phase, making its phase taking more stable.

At the same time, the isotropic plates move concentrically closer or farther away to adapt to the inside of the hole wall. When there is a small angle inside the hole wall, when one of the isotropic plates loses its supporting force, the remaining isotropic plates can still drive the peephole probe to be relatively centered, forming stable imaging.

DETAILED DESCRIPTION

[0020] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described in some examples may be combined in other examples.

[0021] The embodiment of the present invention discloses a real-time depth feedback multi-aperture drilling peek fixing device, such as Figures 1 to 7 As shown, it includes a circular plate 100, an extension line 101 is provided on the surface of the circular plate 100, and a peephole probe 102 is provided at the end of the extension line 101, a synchronization mechanism 200, and the synchronization mechanism 200 includes a carrier 201 provided on the surface of the peephole probe 102, a hollow tooth 202 is provided inside the carrier 201, a plurality of synchronization parts are provided, which are distributed in a circle with the carrier 201 as the axis and assembled inside the carrier 201, a plurality of isoposition parts are provided, which are axially arranged inside the carrier 201 with the carrier 201 as the axis, and real-time correction is made for the synchronization parts based on their execution distance, and a propulsion mechanism 300 is provided on the surface of the carrier 201, and its effective matching length matches the working length of the carrier 201, so as to provide continuous forward thrust when the carrier 201 moves.

[0022] During use, the other end of the extension line 101 is connected to the control and display unit. The display unit is a screen, which transmits the data of the peephole probe 102 to the screen through the extension line 101 in real time, thereby performing real-time drilling display. It is mostly an LCD / OLED screen. The peephole probe 102 is an optical lens, mostly a CCD / CMOS sensor with wide-angle or zoom function. The extension line 101 is an armored tensile cable with built-in power cord, video signal cable and data cable.

[0023] The synchronizer includes an extension leg 211 disposed inside the carrier 201 . The end of the extension leg 211 is fixedly connected to a straight block, and is rotatably connected to a roller 212 via the straight block.

[0024] During use, the extended legs 211 move inside the carrier 201. Under the basic setting, there are three groups, which are equally divided inside the carrier 201 and spaced one hundred and twenty degrees apart in the middle to ensure that each point can be evenly stressed. The three points are equally divided to form geometric symmetry. The contact force between the wheel and the hole wall is naturally balanced, so that the disc is always automatically centered to avoid deflection or jamming. Even if there is local deformation or foreign matter on the hole wall, the three groups of rollers 212 maintain stability through elastic pressure compensation.

[0025] like Figures 2 to 7As shown, the isotope includes an isotope plate 221 disposed inside the carrier 201 , a movable slot is provided inside the isotope plate 221 , a rack is provided inside the movable slot, and an adapter block 222 is provided on the surface of the isotope plate 221 .

[0026] The multiple adapter blocks 222 correspond to the multiple extension legs 211 one by one and are fixedly connected.

[0027] During use, the adapter block 222 drives the extension leg 211 to move inside the carrier 201 through the movement of the isotropic plate 221. When the isotropic plate 221 is squeezed by the internal wall of the hole and works, the hollow tooth 202 is driven to rotate through the rack, and the hollow tooth 202 drives the remaining isotropic plates 221 to work synchronously, compensating for the internal distance of the hole wall, so that the peephole probe 102 is always in a relatively centered position inside the hole wall.

[0028] A telescopic rod 203 is provided on the inner wall of the carrier 201 , a spring 204 is sleeved on the surface of the telescopic rod 203 , and a plurality of groups of fill lights are provided on the side of the carrier 201 close to the peephole probe 102 .

[0029] The end of the telescopic rod 203 is fixedly connected to one of the alignment plates 221 .

[0030] During use, the spring 1 204 on the telescopic rod 203 will drive one of the peer plates 221 to work. The peer plate 221 will be pushed by the thrust to push the roller 212 on the extension leg 211 toward the inside of the hole wall, so that the axis of the carrier 201 is aligned with the axis inside the hole wall, making the peephole probe 102 more accurate and stable in taking photos. When subjected to squeezing force, the peer plate 221 moves into the carrier 201. At the same time, due to the rotation of the rack, the distance between each peer plate 221 is the same. At the same time, the spring 1 204 will also push the peer plate 221 to move outward for distance compensation.

[0031] A plurality of alignment plates 221 are distributed in a stepped manner on the surface of the hollow teeth 202 and mesh with the hollow teeth 202 via racks.

[0032] like Figure 2 As shown, the propulsion mechanism 300 includes an assembly ring 301 arranged on the surface of the carrier 201, a bearing 302 is provided at the end of the assembly ring 301, a spring wire 303 is fixedly connected to the inner ring of the bearing 302, and a handle is provided at the end of the spring wire 303.

[0033] The surface of the assembly ring 301 is connected to the carrier 201 through threads.

[0034] It should be noted that the assembly ring 301 and the carrier 201 are detachable, the length of the extension line 101 is shorter than the length of the spring wire 303, and the bearing 302 is used to prevent the spring wire 303 from rotating and driving the carrier 201 to rotate. Under special circumstances, the spring wire 303 can change the surface into a segmented cone, but still retains a straight length to increase the friction inside the hole wall.

[0035] During use, the spring wire 303 is restricted by the circular plate 100, so that the spring wire 303 can be stably advanced.

[0036] The plurality of extension legs 211 and the rollers 212 are always on the same horizontal line in the working state.

[0037] Working principle: First, buckle the circular plate 100 to the edge of the hole wall. Before buckling, ensure that the synchronization mechanism 200, the propulsion mechanism 300 and the peephole probe 102 are lowered into the hole. Then turn the spring line 303 of the propulsion mechanism 300. At the same time, ensure that the fill light is turned on inside the hole, the peephole probe 102 starts working, and the display unit starts to show the image. The spring line 303 generates a forward thrust as the person turns the handle, extending the synchronization mechanism 200 and the peephole probe 102 into the hole. The extension line 101 is pushed into the circular plate as the spring line 303 is pushed toward the inside of the hole. 100 is synchronously slid out, and the roller 212 slides inside the hole. The spring 204 on the surface of the telescopic rod 203 makes it always roll in contact with the inside of the hole. When the hole is bent due to drilling or geological reasons, the spring line 303 provides forward thrust, and the extended leg 211 is squeezed and retracted toward the inside of the carrier 201. The roller 212 still adheres to the inside of the hole wall and makes a small turn. Or when the peephole probe 102 reaches the deepest part of the hole, the peephole probe 102 starts to work, and as the peephole probe 102 is pulled out, the hole wall is imaged in real time.

[0038] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make more forms of equivalent embodiments based on the inspiration of this embodiment, all of which are protected by this embodiment.
