[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0027] Combine the following Figure 1-Figure 5 The present invention describes a borehole peep instrument pushing device according to an embodiment of the present utility model.
[0028] The utility model embodiment provides a drilling peep instrument pushing device, such as Figure 1-Figure 5 The pushing device of the drilling peep instrument mainly includes three parts: a pushing rod 1, a limit plate 3 and a peep probe 4. Figure 1 As shown, the push rod 1 is a hollow columnar structure, and a plurality of limit adjustment holes 2 are formed on its circumferential side wall (limited by the angle, Figure 1 (not drawn in the figure), the limit plate 3 is movably connected to the push rod 1 through the limit adjustment hole 2, and extends or retracts relative to the outer peripheral side wall of the push rod 1 through the limit adjustment hole 2, wherein the number of limit plates 3 is the same as the number of limit adjustment holes 2 and is installed one-to-one; the peep probe 4 is located at one end of the push rod 1 in the axial direction, and the cable 45 electrically connected to the peep probe 4 extends from the other end of the push rod 1 through the hollow structure of the push rod 1.
[0029] The above-mentioned limit adjustment hole 2 and the limit plate 3 matched therewith can extend relative to the outer wall of the push rod 1 so that the peephole inserted into the corresponding borehole can be limited between the borehole by contacting the inner wall of the borehole, thereby reducing the amplitude of the peephole shaking relative to the borehole during the observation stage as much as possible, which helps the operator to obtain a clearer picture; and when the limit plate 3 is retracted relative to the outer wall of the push rod 1 through the limit adjustment hole 2, the limit between the peephole and the borehole is released, and the peephole can be conveniently further inserted or retracted relative to the borehole, which helps the operator to push the device deeper or withdrawn relative to the borehole, and facilitates observation of different positions of the borehole. The limit structure formed by the cooperation of the limit adjustment hole 2 and the limit plate 3 can also effectively avoid the possibility of excessive friction between the outer wall of the peephole and the borehole while ensuring better cooperation between the borehole and the peephole, which helps to extend the service life of the peephole.
[0030] When the borehole peephole pushing device is inserted into the borehole, when the limit piece extends out relative to the limit adjustment hole 2 and contacts the inner wall of the borehole or even squeezes each other, the push rod 1 can be fixed at the corresponding position relative to the borehole under the action of the relevant force. At this time, the peep probe 4 located on the push rod 1 can also remain stable relative to the borehole, which helps to improve the clarity of the captured image.
[0031] In some embodiments, the peep probe 4 includes a housing 41, a reflective bowl 42, a light source group 43 and a lens 44. Figure 2 As shown, the housing 41 is detachably connected to the push rod 1, the reflector 42 is fixedly installed in the housing 41, the light source group 43 is fixedly connected to the reflector 42, and the lens 44 is installed outside the reflector 42 and connected to the housing 41. The lens 44 is a camera device that can shoot pictures.
[0032] The reflective bowl 42 can help expand the illumination range of the light source, and helps to cooperate with the light source group 43 to obtain a larger illumination range, making the observation process more convenient and efficient.
[0033] In order to achieve a firm connection between the peep probe 4 and the push rod 1, in some embodiments, the shell 41 is snap-fitted to the push rod 1; of course, the shell 41 and at least part of the push rod 1 may also be arranged as an integrated structure.
[0034] Specifically, the cable 45 is electrically connected to the light source group 43 and the lens 44 in the peep probe 4. The cable 45 includes a power supply line and a data transmission line, wherein the power supply line is used to supply power to the light source group 43 and the lens 44, and the data transmission line is used to control the switch and working mode of the lens 44 and the light source group 43, and can also transmit the video and / or picture data taken by the lens 44 in the form of data to the relevant data receiving device connected to the other end of the cable 45. The data receiving device is a prior art and will not be described in detail here.
[0035] The structure of the light source group 43 is described in detail below:
[0036] like Figure 3 As shown, the light source group 43 includes a mounting seat and a light source, wherein the mounting seat is an annular structure and is fixedly installed in the reflective bowl 42, and the number of light sources is multiple and all the light sources are arranged in an annular array on the mounting seat.
[0037] In some embodiments, the light source includes at least two of visible light, ultraviolet light, infrared light, X-ray and fluorescence; when powered on, different light sources can emit light simultaneously or separately, and different crystal materials will emit light of different colors under the stimulation of different light. In combination with a lens 44 that can accept a special spectrum (such as a hyperspectral lens 44, etc.), accurate identification of the distribution of different crystals and cracks can be achieved, thereby providing a better peeping effect.
[0038] The structures and connection methods of the lens 44 and the light source group 43 are prior art and will not be described in detail here.
[0039] It should be noted that, in order to ensure the illumination effect of the light source, in some embodiments, different light sources are arranged at intervals on the mounting base, and light sources of the same type are evenly arranged in a ring shape on the mounting base.
[0040] The matching structure of the above-mentioned limit plate 3 and the limit adjustment hole 2 is specifically described below:
[0041] like Figure 4 and Figure 5 As shown, the above-mentioned limit plate 3 and the limit adjustment hole 2 are slidably matched through the sliding member 5, thereby realizing the movement of the limit plate 3 extending or retracting relative to the outer side wall of the push rod 1.
[0042] Specifically, the sliding member 5 includes a sliding seat 51 and a guide rail 52 that are slidably matched, wherein the sliding seat 51 is formed on the side wall of the limit adjustment hole 2, the number of the sliding seats 51 is at least two and the two sliding seats 51 are symmetrically arranged; the guide rail 52 is formed on the limit plate 3, and the limit plate 3 is slidably matched with the limit adjustment hole 2 through the guide rail 52 and extends or retracts relative to the push rod 1 along the radial direction of the push rod 1; the guide rails 52 are the same as the number of the sliding seats 51 and are arranged one-to-one.
[0043] In some embodiments, Figure 5 As shown, the slide 51 is a T-shaped slide 51, and the corresponding position of the guide rail 52 is recessed to form a recessed guide rail structure for accommodating the T-shaped slide 51, and the guide rail 52 is connected to the slide 51 by sliding fit. At this time, the limit plate 3 fixedly connected to the guide rail 52 can slide relative to the slide 51 under the action of external force.
[0044] In order to better control the movement of the limit plate 3, in some embodiments, a sealing plate 521 is formed at one end of the guide slide rail 52 pointing to the axis of the push rod 1, and a spring 6 is installed between the sealing plate 521 and the corresponding slide seat 51, and the spring 6 is always in a non-stretched state; a pull wire 31 is also installed on the side of the limit plate 3 facing the inside of the push rod 1, and the pull wire 31 extends outward through the hollow structure inside the push rod 1 and the end of the push rod 1 away from the peep probe 4.
[0045] The spring 6 can apply a driving force to the limit plate 3 through the guide rail 52 fixedly connected to the limit plate 3 and drive the limit plate 3 to extend outward relative to the outer wall of the push rod 1, and the pull wire 31 can apply a pulling force in the opposite direction to the limit plate 3. By adjusting the pulling force applied by the operator to the pull wire 31, the push rod 1 can be conveniently switched between the limit state and the release state.
[0046] Taking into account that the lengths of the drilled holes may be different, in order to facilitate operation, in some embodiments, the push rod 1 may be configured as a telescopic structure (the telescopic rod structure is prior art and will not be described in detail here), or a detachable structure with adjustable length.
[0047] Specifically, the push rod 1 includes a first rod body 11 and a second rod body 12 that are detachably connected, wherein the first rod body 11 is used to install the above-mentioned peep probe 4, and the second rod body 12 is connected to the end of the first rod body 11 away from the peep probe 4, and the number of the above-mentioned second rod bodies 12 is several.
[0048] It should be noted that both the first rod body 11 and the second rod body 12 are hollow structures, and the space in the middle is used to accommodate the cable 45 and the pull wire 31 .
[0049] In order to ensure the stability of the peep probe 4 as much as possible, the above-mentioned limit adjustment hole 2 is formed on the peripheral side wall of the first rod body 11, that is, the limit plate 3 is movably installed on the first rod body 11.
[0050] The detachably connected first rod body 11 and second rod body 12 can be connected by means of a matching structure of a protrusion and an L-shaped slot; of course, they can also be connected by means of a threaded connection.
[0051] Specifically, Figure 4 As shown, the inner wall of one end of the first rod body 11 used for connecting with the second rod body 12 is formed with a stepped hole structure, and an internal thread is formed on the inner side wall of the stepped hole structure. One end of the second rod body 12 is protruded outward to form an external stepped hole, and an external thread is formed on the external stepped hole, and the other end is recessed inward to form an internal stepped hole and an internal thread located on the internal stepped hole; the external thread and the internal thread cooperate with each other, thereby realizing the threaded connection between the first rod body 11 and the second rod body 12, and the detachable connection between two adjacent second rod bodies 12.
[0052] The step structure can ensure that the external thread structure is always located inside the first rod body 11 or the second rod body 12 connected thereto, thereby preventing debris in the drilled hole from entering the threaded connection and contaminating the threads, ensuring that the various rod bodies of the push rod 1 can be smoothly disassembled and assembled without being damaged by contamination from debris.
[0053] In some embodiments, a waterproof layer is coated on the outer wall of the first rod body 11 .
[0054] Since water may seep into the borehole, in order to prevent the peep probe 4 installed on the first rod body 11 from being damaged, a waterproof layer is coated on the outer wall of the first rod body 11; of course, a waterproof layer can also be coated on the inner wall of the first rod body 11, especially on the side adjacent to the peep probe 4, to ensure that water vapor and the like will not corrode the peep probe 4 through the first rod body 11. Of course, the peep probe 4 itself also has good moisture-proof and dust-proof treatment.
[0055] It can be understood that the borehole peep device push device provided in this embodiment can better overcome the problem of blurred images and poor peep detection effect of traditional peep equipment. The above structures can effectively protect the peep probe, so that the peep probe can more clearly observe the internal structure exposed by the drilling part of the surrounding rock, thereby better providing a reference basis for the design of roof management, tunnel support and other solutions.
