[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to facilitate understanding of the borehole peep lens decontamination device and the borehole peep instrument provided by the present invention, the application background is first introduced. At present, mines generally use borehole peep instruments to intuitively monitor the damage of mine overburden before and after mining. Through the peep detection of overburden geology and broken structure, more scientific control measures can be provided for roof and surrounding rock control, gas control, etc.

[0024] During the process of drilling and peering into the overburden in a mine, when the overburden is mudstone or the rock layer is relatively broken, due to the influence of the wet drilling process, residual coal slag or large pieces of rock mud may remain on the wall of the borehole. Once the peering lens passes through these areas, the peering lens is easily contaminated, and the peering field of view is severely limited, resulting in the interruption of the peering work.

[0025] For this reason, the peep lens needs to be taken out of the borehole and wiped many times, or even the borehole needs to be flushed or re-drilled using a drilling rig many times, which not only seriously affects the progress of the work, but also wastes a lot of manpower and material resources.

[0026] In view of the above problems, the present invention provides a drilling peep lens dirt removal device and a drilling peep instrument, which can effectively avoid the problem of limited field of view of the peep lens due to contamination, thereby ensuring work progress and reducing the consumption of manpower and material resources.

[0027] Combine the following Figure 1-Figure 3 The invention discloses a borehole peep lens dirt removing device and a borehole peep instrument.

[0028] Reference Figure 1A drilling peep lens cleaning device comprises a push rod 1, a spray mechanism 2 and a wiping mechanism 3; wherein, a connector 10 is provided at one end of the push rod 1 along the axial direction, the connector 10 is suitable for connecting to the peep lens 4, and a cleaning liquid flow channel is provided in the push rod 1; the spray mechanism 2 is connected to the push rod 1, the inlet of the spray mechanism 2 is connected to the cleaning liquid flow channel, and the outlet is close to and toward the lens area 40 of the peep lens 4; the wiping mechanism 3 comprises a power member 30 and a wiping member 31, the power member 30 has a driving end that can move close to or away from the lens area 40, and the wiping member 31 is connected to the driving end, so that it can move close to or away from the lens area 40 driven by the driving end.

[0029] In a specific application scenario, when performing peep detection on rock formations, the peep lens 4 is connected to the connector 10, and the peep lens 4 is sent into the borehole through the push rod 1 to perform peep detection on the rock formation on the borehole wall. When the field of view is limited due to contamination of the peep lens 4, the cleaning liquid is transported to the spray mechanism 2 through the cleaning liquid flow channel in the push rod 1. The spray mechanism 2 can spray and clean the lens area 40 of the peep lens 4, thereby washing away the dirt on the lens. After the dirt on the lens is washed away, the wiping mechanism 3 is started, and the driving end of the power member 30 drives the wiping member 31 to move close to the lens area 40 to wipe the lens area 40 of the peep lens 4, wipe off the water stains in the lens area 40, and prevent the water stains from affecting the field of view. After the water stains are wiped off, the driving end of the power member 30 drives the wiping member 31 to move away from the lens area 40 and return to its original position, so that the lens area 40 is exposed to facilitate continued detection.

[0030] Compared with the related art, when the field of view is limited due to contamination of the peep lens 4, the peep lens 4 can be cleaned in the borehole by the spray mechanism 2 and the wiping mechanism 3, without the need to take the peep lens 4 out of the borehole for multiple times for wiping, and without the need to flush the borehole or re-drill, thereby ensuring work progress and saving manpower and material resources.

[0031] In one embodiment of the present invention, the push rod 1 is configured as a hollow tubular structure, so that the channel inside the push rod 1 is formed as a cleaning liquid flow channel. The connector 10 is fixedly connected to the end of the push rod 1, and can be specifically welded, or can be connected by threaded connection or other connecting components. The specific form of the connector 10 can be designed according to the interface form of the peep lens 4. For example, when the peep lens 4 adopts a threaded interface, the connector 10 can be configured as a threaded form to facilitate docking with the threaded interface of the peep lens 4. When the peep lens 4 adopts a snap-on or plug-in interface, the connector 10 can be configured with a corresponding matching structure to facilitate snap-on or plug-in adaptation with the peep lens 4. In other words, when a peep lens 4 with a different interface form is adopted, the form of the connector 10 will also be different. Therefore, in the embodiment of the present invention, there is no specific restriction on the structure and form of the connector 10.

[0032] In one embodiment of the present invention, the spray mechanism 2 includes a spray pipe 20 and a nozzle 21; wherein, a plurality of spray pipes 20 are arranged around the connector 10, the inlet of the spray pipe 20 is connected to the push rod 1 and communicated with the cleaning liquid flow channel, and the outlet is close to and toward the lens area 40; the nozzle 21 is connected to the outlet of the spray pipe 20.

[0033] In actual applications, the lens area 40 is generally located on the outer peripheral side of the peep lens 4. When cleaning the peep lens 4, the cleaning liquid enters the multiple spray pipes 20 through the cleaning liquid flow channel. The multiple spray pipes 20 can spray and clean different positions of the lens area 40 at different positions, thereby improving the cleaning effect.

[0034] Specifically, multiple spray pipes 20 can be evenly arranged around the connector 10. For example, when there are two spray pipes 20, the two spray pipes 20 are symmetrically arranged with the connector 10 as the center. When there are three spray pipes 20, the three spray pipes 20 form an angle of 120 degrees. When there are four spray pipes 20, the four spray pipes 20 are arranged at an angle of 90 degrees, and so on. In this way, it can be ensured that the spray range of the spray pipe 20 evenly covers the entire lens area 40 of the peep lens 4, ensuring the cleaning effect.

[0035] In this embodiment, four spray pipes 20 are provided, and the four spray pipes 20 are arranged at an angle of 90 degrees.

[0036] Specifically, refer to Figure 1 and Figure 2 The spray pipe 20 includes an integrally formed first section 200, a second section 201 and a third section 202; wherein the inlet end of the first section 200 is connected to the push rod 1 and communicated with the cleaning liquid flow channel to form the inlet of the spray pipe 20, and the outlet end extends along the radial direction of the push rod 1; the inlet end of the second section 201 is communicated with the outlet end of the first section 200, and the outlet end of the second section 201 extends along the axial direction of the push rod 1, so that the spray pipe 20 gradually approaches the lens area 40; the inlet end of the third section 202 is communicated with the outlet end of the second section 201 and is arranged at an angle to the second section 201. In the axial direction of the push rod 1, the third section 202 gradually approaches the axis deviation of the push rod 1, so that the outlet end of the third section 202 can be closer to and toward the lens area 40 of the peep lens 4, and the outlet end of the third section 202 forms the outlet of the spray pipe 20, and the nozzle 21 is connected to the outlet end of the third section 202.

[0037] Such an arrangement enables the outlet of the spray pipe 20 to be close to and toward the lens area 40. When cleaning the peep lens 4, the cleaning liquid can be directly flushed to the lens area 40 of the peep lens 4 through the nozzle 21, and the dirt in the lens area 40 can be flushed down under the action of water pressure, which is beneficial to improving the cleaning effect of the spray mechanism 2.

[0038] In some optional embodiments, the spray pipe 20 and the push rod 1 can be fixed by welding or connected by threaded joints, and the specific selection can be made according to actual needs. In addition, the spray head 21 and the spray pipe 20 can be fixed by welding or threaded connection, and the specific specifications and models of the spray head 21 can be flexibly selected according to actual working conditions, and are not specifically limited in the embodiments of the present invention.

[0039] After the dirt on the peep lens 4 is washed away by the spray mechanism 2 , the water stains need to be wiped away by the wiping mechanism 3 to avoid the water stains from affecting the field of view of the peep lens 4 .

[0040] In one embodiment of the present invention, the wiper 31 is annular and forms a wiping area on the inner circumference of the ring. In the axial direction, the wiper 31 corresponds to the position of the peep lens 4 and can move closer to or away from the peep lens 4 under the drive of the power member 30.

[0041] In actual application, after the spray mechanism 2 cleans the dirt on the peep lens 4, the power member 30 drives the annular wiping member 31 to move close to the peep lens 4 and sleeve the peep lens 4. The wiping area located on the inner circumference of the wiping member 31 can wipe the lens area 40 on the outer circumference of the peep lens 4, which is conducive to improving the wiping efficiency. After wiping is completed, the power member 30 drives the wiping member 31 to move away from the peep lens 4 and finally return to its original position to avoid affecting the image acquisition.

[0042] Specifically, the wiper 31 may be a ring-shaped cotton wiper.

[0043] In some embodiments, according to different working principles, there are multiple options for the wiper 31, for example, a linear drive element such as an electric push rod and a linear motor can be used.

[0044] Reference Figure 1 and Figure 3 In one embodiment of the present invention, the power member 30 includes a mounting seat 300, a fixed pulley 301, a chain 302 and a motor 303; wherein the fixed pulley 301 is fixedly connected to the mounting seat 300, and two fixed pulleys 301 are arranged alternately along the axial direction of the push rod 1; the chain 302 is wound between the two fixed pulleys 301, and the wiping member 31 is fixedly connected to the chain 302; the motor 303 is fixedly connected to the mounting seat 300, and the output end of the motor 303 is connected to the sprocket 304, and the sprocket 304 is engaged with the chain 302.

[0045] In actual work, the motor 303 drives the sprocket 304 to rotate, the sprocket 304 drives the chain 302 to rotate, and the chain 302 moves between the two fixed pulleys 301 to drive the wiping member 31 to move closer to or away from the peep lens 4, thereby wiping the peep lens 4.

[0046] Specifically, the motor 303 may be a micro servo motor 303 .

[0047] Specifically, the wiping member 31 is sleeved outside the mounting seat 300 , and the motor 303 , the fixed pulley 301 and the chain 302 are all located in the inner area of ​​the ring of the wiping member 31 to avoid interference with the movement of the wiping member 31 .

[0048] Specifically, the wiping member 31 and the chain 302 may be connected in a detachable manner to facilitate cleaning and replacement of the wiping member 31 .

[0049] In one embodiment of the present invention, the mounting base 300 is connected to the other end of the peep lens 4 relative to the connector 10. Through the above technical solution, the peep lens 4 can provide a connection base for the wiping mechanism 3, which is convenient for the installation of the wiping mechanism 3, and can also keep the wiping mechanism 3 away from the spray mechanism 2 to avoid interference between the two. In addition, using the peep lens 4 as the connection base for the wiping mechanism 3 can make the overall structure of the device more compact.

[0050] Specifically, a thread is provided at the other end of the peep lens 4 relative to the mounting seat 300, and the mounting seat 300 and the peep lens 4 are connected by threads.

[0051] Generally speaking, the peep lens 4 includes a metal shell that is covered on the outside to provide protection for the internal structure of the peep lens 4. Threads are set on the shell to provide an installation basis for the wiping mechanism 3.

[0052] Of course, the connection methods between the mounting base 300 and the peep lens 4 include but are not limited to the above-mentioned connection methods, and other methods that can achieve the connection between the wiping mechanism 3 and the peep lens 4 are also applicable.

[0053] In one embodiment of the present invention, a guide wheel 5 is connected to the mounting seat 300. When performing peep detection in the borehole, the guide wheel 5 can cooperate with the hole wall to play a supporting and guiding role, reduce the pushing resistance, and improve the smoothness of pushing the peep lens 4 into the borehole.

[0054] In one embodiment of the present invention, the push rod 1 includes a plurality of detachably connected segments. By adjusting the number of segments, the pushing distance of the peep lens 4 into the borehole can be controlled.

[0055] Specifically, the segment includes a first segment 11 and a plurality of second segments 12; the connector 10 and the spray mechanism 2 are fixedly connected to the first segment 11, the second segment 12 and the first segment 11 and the adjacent second segments 12 are detachably connected, and at least the first segment 11 is made of metal. By setting the first segment 11 to be made of metal, the welding and fixing of the connector 10 and the spray pipe 20 to the push rod 1 can be facilitated.

[0056] In one embodiment of the present invention, the second section 12 is made of plastic. Compared with the original solid metal probe rod, the plastic tube can be set with a larger diameter, which increases the force-bearing area, enables the pushing personnel to better bear the force, and at the same time reduces the shaking of the lens during the deep hole measurement process, so as to obtain better test results.

[0057] Specifically, the second section 12 includes but is not limited to a ppr (polypropylene random copolymer pipe) pipe.

[0058] Specifically, the first segment 11 and the second segment 12 and adjacent second segments 12 may be butt-jointed using threaded joints.

[0059] In one embodiment of the present invention, the dirt removal device also includes a water supply pipe 6 and a valve 7; the water supply pipe 6 and the valve 7 are detachably connected to the other end of the push rod 1 relative to the connecting head 10, wherein the water supply pipe 6 is used to supply water to the dirt removal device; the valve 7 is used to control the water pressure.

[0060] In one embodiment of the present invention, a second segment 12 can be used as a connecting pipe 13, the valve 7 is fixedly connected to the connecting pipe 13, the water supply pipe 6 is connected to the valve 7, and the water supply pipe 6 and the valve 7 are detachably connected to the push rod 1 by disassembling the connecting pipe 13.

[0061] Specifically, the valve 7 can be a ball valve, and the water supply pipe 6 can be a mining ø19 water pipe.

[0062] It is to be understood that, without mutual contradiction, those skilled in the art may combine and combine the different embodiments or examples and the features of the different embodiments or examples described in this specification.

[0064] A drilling peep instrument comprises a peep lens 4 and a drilling peep lens decontamination device provided by any of the above embodiments, wherein the peep lens 4 is fixedly connected to a connector 10.

[0065] According to the drilling peep lens decontamination device and the drilling peep instrument provided by the embodiment of the present invention, when the field of view is limited due to the contamination of the peep lens 4, the cleaning liquid is transported to the spray mechanism 2 through the cleaning liquid flow channel in the push rod 1, and the spray mechanism 2 can spray and clean the lens area 40 of the peep lens 4, so as to rinse the dirt on the lens. After the dirt on the lens is rinsed, the wiping mechanism 3 is started, and the driving end of the power member 30 drives the wiping member 31 to move close to the lens area 40, so as to wipe the lens area of ​​the peep lens 4. 40 is used to wipe the water stains in the lens area 40 to prevent the water stains from affecting the field of vision. After the water stains are wiped, the driving end of the power member 30 drives the wiping member 31 to move away from the lens area 40 and return to its original position, so that the lens area 40 is exposed to facilitate continued detection. Compared with the related art, the peep lens 4 can be cleaned in the borehole by the spraying mechanism 2 and the wiping mechanism 3, without the need to take the peep lens 4 out of the borehole for multiple times to wipe it, and without the need to flush the borehole or re-drill, thereby ensuring the work progress and saving manpower and material resources.
