[0003] At present, peephole equipment is increasingly used in the mining field, but there are still the following shortcomings: the existing peephole equipment cannot meet the requirements of multi-diameter boreholes. Specifically, due to the different uses of underground drilling holes, their diameters are different, and the existing peephole equipment cannot be effectively applied to boreholes of various aperture sizes, resulting in the need to frequently replace peephole equipment of different specifications during the peephole process, and the disassembly and assembly steps are cumbersome, which greatly reduces work efficiency. Utility Model Content

When in use, after the borehole instrument is sent into a borehole, the volume of the air bag is changed by inflating the air bag through the inflation tube, so that the roller on the air bag moves away from the sleeve, so as to adapt to the peeping of boreholes of different diameters. The borehole instrument is suitable for boreholes of various aperture sizes, has strong versatility, and does not require frequent replacement of the peeping device during the peeping process, thereby greatly improving work efficiency.
[0007] Furthermore, one end of the inflation tube passes through the sleeve and is connected to the airbag, and the other end extends into the support rod, extends from one end of the support rod where the propulsion device is arranged, and is connected to an external air source.
[0008] In order to improve the stability of the peephole instrument, at least four airbags are evenly distributed around the outer circle of the sleeve, and at least two rollers on the airbags are arranged along the propulsion direction.
[0009] Furthermore, there is a gap between the support rod and the sleeve, and a plurality of connecting rods are arranged in the gap and connected by the connecting rods. This structural design improves the stability of the equipment.
[0010] For ease of use, a camera is set at one end of the support rod, and a number of light balls are arranged around the camera. The light balls are LED light balls with adjustable brightness, which can change the brightness according to different environments, thereby improving the imaging quality.
[0011] As an implementation method, the propulsion device includes multiple propulsion rods that are detachably connected in sequence, and the propulsion rods are provided with a number of pipeline clips along their length directions, which are used to fix the inflation tube and the camera cable to prevent entanglement, thereby improving the convenience and safety of the equipment.
[0012] In the inflatable variable-diameter peephole instrument as described above, the specifications of the several airbags are the same, and the material of the outer side of the airbag is a material that can prevent debris from piercing the internal inflation layer, such as canvas.
[0013] To ensure the smoothness of peephole imaging, the roller is made of flexible rubber, and a number of shock-absorbing protrusions are provided on the outer surface of the roller, and the inside of the protrusions is hollow. When advancing in a rough drilled hole, when the roller presses over the protruding particles, the protrusions can act as a shock-absorbing effect, ensuring the smoothness of peephole imaging.
[0014] The beneficial effect of the inflatable variable-diameter peephole instrument of the utility model is that, through the unique design of arranging a plurality of air bags on the outer ring of the sleeve and arranging rollers on the outside of the air bags, adaptability to drilling holes of different diameters is achieved, and there is no need to frequently replace the peephole device during the peephole process of drilling holes of different diameters, which greatly improves the work efficiency.

[0025] Combination Figure 1 The present embodiment provides an inflatable variable-diameter peephole instrument, including a peephole instrument body and a propulsion device connected thereto, the propulsion device being used to send the peephole instrument body into a borehole, the peephole instrument body comprising a sleeve 1 and a camera device 2 arranged inside the sleeve and a walking device 3 arranged outside the sleeve, the camera device 2 being used to record rock crushing conditions at different depths in the borehole, the walking device 3 being used to support the camera device 2 and realize the operation of the camera device 2 in the borehole.
[0026] Regarding the specific structure of the camera device 2, Figure 1 and Figure 3 Specifically, the camera device 2 includes a support rod 21 disposed inside the sleeve 1 and a camera 22 disposed at one end of the support rod 21 .
[0027] For the specific structure of the propulsion device, combined with Figure 1 and Figure 5 Specifically, the propulsion device is connected to the other end of the support rod 21, and the walking device 3 includes a plurality of airbags 31 arranged circumferentially around the outer circle of the sleeve 1. The inner side of the airbag 31 is connected to the sleeve 1, and a roller 34 is provided on the outer side. The airbag 31 is connected to the external air source through an inflation tube 32, wherein the connection between the airbag 31 and the sleeve 1 includes but is not limited to connection by means of strong adhesive or mechanical structure connecting bolts.
[0028] There is a gap between the support rod 21 and the sleeve 1, and a plurality of connecting rods 6 are arranged in the gap and connected by the connecting rods 6. This structural design improves the stability of the device.
[0029] The specifications of the plurality of airbags 31 are the same, and the material of the outer side of the airbag 31 is a material that can prevent debris from puncturing the inner inflation layer, such as canvas.
[0030] Preferably, there are at least four airbags 31 evenly distributed around the outer circle of the sleeve 1 .
[0031] The four airbags 31 are all inflatable and independent airbags 31 , which are arranged on the outer wall of the sleeve 1 at 90° in a circumferential direction. The airbags 31 are inflated and deflated by connecting to the air pipe, and the diameter of the variable-diameter sleeve 1 is changed by changing the volume of the airbags 31 .
[0032] Combination Figure 2 and Figure 4 One end of the inflation tube 32 passes through the sleeve 1 and is connected to the airbag 31, and the other end extends into the support rod 21, and extends from one end of the support rod 21 where the propulsion device is set, and is connected to an external air source.
[0033] Specifically, the inflation tube 32 includes a delivery tube section and four inflation tube 32 sections connected thereto. The delivery tube end extends from one end of the support rod 21 close to the propulsion device and is connected to an external air source. The inner ends of the four inflation tube 32 sections are connected to the delivery tube section, and the outer ends extend from the support rod 21, pass through the sleeve 1 respectively, and are connected to the four airbags 31 respectively, thereby inflating and deflation the four airbags 31.
[0034] Combination Figure 7 The rollers 34 on each airbag 31 are arranged along the propulsion direction of the airbag 31, and at least two rollers 34 are arranged respectively near the two ends of the propulsion direction of the airbag 31 to improve the stability of the peephole instrument.
[0035] The roller 34 is rotatably arranged on the outside of the airbag 31 through the mounting seat 33. The mounting seat 33 is a U-shaped plate structure. The two ends of the rotating shaft of the roller 34 are rotatably connected to the two sides of the opening of the mounting seat 33. The horizontal section between the two sides of the opening of the mounting seat 33 is connected to the outside of the airbag 31, and the connection between the horizontal section roller 34 of the mounting seat 33 and the airbag 31 includes but is not limited to connection by means of strong glue or mechanical structure connecting bolts.
[0036] The roller 34 is made of flexible rubber, and a plurality of shock-absorbing protrusions 341 are provided on the outer surface of the roller 34, and the interior of the protrusion 341 is hollow. When advancing in a rough borehole, the hollow protrusion 341 can play a shock-absorbing role when passing through the protruding particles on the inner wall of the borehole, thereby ensuring the smoothness of the peephole imaging.
[0037] Combination Figure 1 and Figure 3 When the airbag 31 is in working state, the roller 34 is arranged on the side of the airbag 31 away from the sleeve 1, and the rotation axis of the roller 34 is perpendicular to the axis of the sleeve 1.
[0038] Combination Figure 3A camera 22 is disposed at one end of the support rod 21, and a plurality of light balls are disposed around the camera 22. The cross-section of the camera 22 is circular, and the plurality of light balls are arranged in a circle around the camera 22. The light balls are LED light balls with adjustable brightness, which can change the brightness according to different environments, thereby improving the imaging quality.
[0039] For the specific structure of the propulsion device, combined with Figure 6 Specifically, the propulsion device includes a plurality of propulsion rods 4 which are detachably connected in sequence, and a plurality of pipeline buckles 5 are provided on the propulsion rods 4 along their length direction, and the buckles are arranged on the propulsion rods 4 at a circumferential angle of 180°, so as to fix the cables of the inflation tube 32 and the camera 22 to prevent entanglement, thereby improving the convenience and safety of the equipment.
[0040] Each push rod 4 is provided with an external thread at the front end and an internal thread at the rear end. When pushing, the external thread at the front end of the first push rod 4 is threadedly connected to the screw hole at the rear end of the sleeve 1, and the external thread at the front end of the second push rod 4 is threadedly connected to the screw hole at the rear end of the first push rod 4. Then, the sleeve 1 is sent into the drill hole by connecting them in sequence according to a regular pattern.
[0041] When in use, first deflate the four air bags 31 (such as Figure 5 As shown), in order to reduce the outer diameter of the device and facilitate insertion into the borehole, the uninflated sleeve 1 is then sent into the borehole, and the inflation tube 32 is used to inflate the inside of the airbag 31 to change its volume. At this time, the roller 34 on the airbag 31 moves outward away from the sleeve 1, and the inflation is stopped after it is in close contact with the inner wall of the borehole. Subsequently, the thrust rods 4 are connected one by one to send the sleeve 1 into the borehole. At this time, the camera 22 performs operations such as image capture and video recording. During this process, the brightness of the light ball is adjusted according to the situation in the hole to provide lighting support for the camera 22 to obtain clear image data, thereby obtaining high-quality imaging.
[0042] During the process of underground borehole peep, it is often necessary to conduct long-term observation of a certain position. When the drilling angle is non-horizontal, hovering observation of a certain position often requires the assistance of other equipment. The existing peep equipment cannot achieve hovering observation at any position. When using the present peep instrument, when a certain position in the borehole needs to be peeped for a long time, continue to inflate the airbag 31. Due to the increase in the volume of the airbag 31, the pressure of the variable diameter sleeve 1 on the inner wall of the borehole increases, so that the peep instrument can be fixed at this position for long-term observation.
[0043] The peephole instrument can be adapted to the peepholes of different apertures, has strong versatility, and does not require frequent replacement of the peephole equipment during the peephole process, which greatly improves work efficiency; it can realize hovering observation at any position in a non-horizontal borehole; and at the same time, it can reduce the influence of irregular boreholes, rough borehole walls, and protruding particles on the borehole wall on the peephole imaging results.
