[0021] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0022] Beneficial effects of the present invention:

[0023] 1. The present invention can fully clean the outer surface and probe part of the sensor by providing a cleaning component. When cleaning the sensor probe, the sensor probe is raised and lowered. At this time, the outer wall of the sensor probe drives the friction wheel to rotate through friction force, and the transmission shaft drives the cleaning wheel and the first brush to rotate, so that the sensor probe can be cleaned by the cleaning wheel and the first brush during the lifting process, so that the dust and debris attached to the outer wall of the sensor probe are cleaned up, keeping the sensor clean and tidy. Secondly, when the sensor probe needs to be cleaned, start the No. 2 motor, the rotation of the No. 2 motor drives the reciprocating screw to rotate, and the driving rod rotates synchronously at the same time, the driving rod drives the driving gear to rotate, and the driving gear drives the gear to rotate, so that the cleaner rotates, and the cleaner cleans the outer wall of the sensor probe.

[0024] 2. The present invention can reduce the humidity of the air inside the device by setting a moisture-absorbing cotton. Moist air enters the inside of the moisture-absorbing cotton, and the moisture is absorbed by the moisture-absorbing cotton. When the moisture-absorbing cotton is saturated, the extrusion plate squeezes the moisture-absorbing cotton during the descending process, causing the moisture inside the moisture-absorbing cotton to flow out. Then, the moisture flows out of the protection cylinder through the drain hole, realizing the dehumidification function.

[0025] 3. The present invention can achieve secondary buffer protection through the setting of a buffer cavity. Since the connecting holes have a small diameter, when the vibration amplitude is large, the downward pressure on the sealing plate is large. At this time, a large amount of damping liquid needs to flow out, and the small diameter of the connecting hole requires a longer time for the damping liquid to flow out. Thus, the first buffer is carried out by utilizing the flow difference of the damping liquid to protect the sensor. When the damping liquid enters the inside of the buffer cavity, the liquid level of the damping liquid rises to reach the height of the blocking block. Subsequently, the damping liquid flows upward from the pressure relief hole and enters above the blocking block. Similarly, the secondary buffer is carried out by using the pressure relief hole, effectively protecting the sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3, A mounting base for a tunneling machine-mounted sensor, comprising a bottom plate 1, a protective cylinder 2 and a cleaning assembly 3. The top of the bottom plate 1 is provided with a protective cylinder 2. The top of the protective cylinder 2 is provided with a cover plate 21. The top of the cover plate 21 is provided with a plurality of cleaning assemblies 3. The cleaning assembly 3 includes a cleaning plate 30 mounted on the top of the cover plate 21. The cleaning plate 30 is in an arc shape with a narrow top and a wide bottom, and a plurality of cleaning plates 30 are circularly distributed on the cover plate 21. A plurality of transmission shafts 31 are mounted on the inner wall of the cleaning plate 30. A cleaning wheel 32 is mounted on the outer wall of the transmission shaft 31. A first brush 33 is circumferentially mounted on the outer wall of the cleaning wheel 32. A belt 34 is circumferentially mounted on the outer wall of the transmission shaft 31, and a plurality of transmission shafts 31 are drivingly connected through the belt 34. A fixing hole 22 is formed in the top of the cover plate 21, and a plurality of cleaning plates 30 are distributed around the fixing hole 22. A friction wheel 23 is mounted on the inner wall of the cover plate 21. A driven wheel 24 is mounted on the inner wall of the cover plate 21. A connecting belt 25 is circumferentially mounted on the outer wall of the driven wheel 24, and the driven wheel 24 and the friction wheel 23 are drivingly connected through the connecting belt 25. The driven wheel 24 and the transmission shaft 31 are drivingly connected through the belt 34.

[0037] Specifically, when the sensor probe 47 is inserted into the interior of the device, at this time, the detection head part of the sensor probe 47 is located in the middle of a plurality of cleaning plates 30, and the outer wall of the cleaning plate 30 is in contact with the outer wall of the sensor probe 47. At this time, the sensor probe 47 can be clamped and fixed by the cleaning plate 30;

[0038] It should be noted that when cleaning the sensor probe 47, the sensor probe 47 moves up and down. At this time, the outer wall of the sensor probe 47 drives the friction wheel 23 to rotate through friction. The rotation of the friction wheel 23 drives the driven wheel 24 to rotate through the connecting belt 25. The driven wheel 24 drives a plurality of transmission shafts 31 to rotate through the belt 34. The transmission shafts 31 drive the cleaning wheels 32 and the first brushes 33 to rotate. Thus, during the up and down movement of the sensor probe 47, it can be cleaned by the cleaning wheels 32 and the first brushes 33, so that the dust and debris attached to the outer wall of the sensor probe 47 are cleaned off, keeping the sensor clean and tidy.

[0039] Please refer to Figure 1 and Figure 2 , A plurality of triangular support plates 11 are mounted on the top of the bottom plate 1. A plurality of mounting bolts 12 penetrate through the top of the bottom plate 1, and the outer wall of the support plate 11 is fixedly connected to the outer wall of the protective cylinder 2. A rubber pad 13 is mounted at the bottom of the support plate 11.

[0040] Specifically, when installing this device, the plurality of mounting bolts 12 are installed at the predetermined positions of the tunneling machine. The rubber pad 13 can reduce the impact of the vibration of the tunneling machine on the sensor and achieve the damping function.

[0041] Please refer to Figure 4 andFigure 7 , a partition plate 4 is installed on the inner wall of the protection cylinder 2. A circular limiting cylinder 41 is installed through the top of the partition plate 4. A first spring 42 is installed on the inner bottom wall of the limiting cylinder 41. The top of the first spring 42 is installed with a sealing plate 43, and the sealing plate 43 slides up and down inside the limiting cylinder 41. The top of the sealing plate 43 is installed with a protection shell 44. A buffer pad 46 is installed on the inner wall of the protection shell 44. A plurality of rollers 45 are installed on the outer wall of the protection shell 44, and the rollers 45 are in contact with the inner wall of the limiting cylinder 41. A sensor probe 47 is installed on the inner wall of the buffer pad 46. A buffer cavity 6 is opened on the inner bottom wall of the protection cylinder 2. A connection hole 61 is opened on the outer wall of the limiting cylinder 41. Two blocking blocks 62 are installed on the inner wall of the buffer cavity 6. A pressure relief hole 63 is opened on the top of the blocking block 62. A plurality of buffer pipes 64 are installed on the inner wall of the protection cylinder 2. A buffer spring 65 is installed on the inner wall of the buffer pipe 64. A buffer rod 66 is installed on the outer wall of the buffer spring 65. One end of the buffer rod 66 is installed with an arc-shaped protection plate 67, and the outer wall of the protection plate 67 is in contact with the outer wall of the sensor probe 47.

[0042] Specifically, after installing this device, insert the sensor probe 47 into the inside of the protection shell 44. The bottom of the sensor probe 47 is in contact with the buffer pad 46. The buffer pad 46 can further weaken the vibration of the roadheader, so as to ensure that the sensor can accurately detect data. At the same time, after the sensor probe 47 enters the inside of the limiting cylinder 41, the buffer rod 66 is contracted into the inside of the buffer pipe 64 at the same time, and the buffer spring 65 contracts, so that the protection plate 67 contracts. After the sensor enters the inside of the limiting cylinder 41, release the buffer rod 66, so that the protection plate 67 can be close to the outer wall of the sensor probe 47, thereby fixing the sensor inside the limiting cylinder 41 and realizing the fixing function;

[0043] It should be noted that when the sensor probe 47 is subjected to a large vibration, it will move up and down. At this time, the protection shell 44 drives the sealing plate 43 to move up and down inside the limiting cylinder 41. At this time, the rollers 45 slide inside the limiting cylinder 41 to prevent the sensor from tilting in other directions;

[0044] It should be noted that when the sealing plate 43 descends, it squeezes the damping liquid stored inside the limiting cylinder 41. The damping liquid flows out from the connection hole 61 and then enters the inside of the buffer cavity 6. Since the hole of the connection hole 61 is small, when the vibration amplitude is large, the downward pressure of the sealing plate 43 is large. At this time, a large amount of damping liquid needs to flow out. The small aperture of the connection hole 61 makes the damping liquid flow out for a longer time, so as to use the flow difference of the damping liquid for the first buffer to protect the sensor;

[0045] It should be noted that when the damping liquid enters the inside of the buffer chamber 6, the liquid level of the damping liquid rises to the height of the blocking block 62, and then the damping liquid flows upward from the pressure relief hole 63 and enters above the blocking block 62. Similarly, the pressure relief hole 63 is used for secondary buffering, effectively protecting the sensor;

[0046] It should be noted that when the external vibration or extrusion disappears, the damping liquid will flow downward along the inclined surface of the blocking block 62, and then flow back into the inside of the buffer chamber 6 along the pressure relief hole 63, so as to facilitate the next buffering and realize the protection function of the sensor.

[0047] Please refer to Figure 5 , a filter screen 5 is installed at the top of the partition plate 4, an exhaust fan 51 is installed at the bottom of the partition plate 4, a rotating rod 52 is installed on the inner bottom wall of the protection cylinder 2 through a bearing, a fan blade 53 is installed on the outer wall of the rotating rod 52, staggered reciprocating threads 54 are provided on the outer wall of the rotating rod 52, a blocking plate 56 is installed on the outer wall of the rotating rod 52, a slider 55 is installed on the outer wall of the reciprocating thread 54 through a thread, an extrusion plate 57 is installed on the outer wall of the slider 55, a moisture absorbent cotton 58 is installed on the inner bottom wall of the protection cylinder 2, and the moisture absorbent cotton 58 is located below the extrusion plate 57, and a drain hole 59 is provided at the bottom of the protection cylinder 2.

[0048] Specifically, when cleaning and drying the gas inside the protection cylinder 2, the exhaust fan 51 is started, and the gas inside the protection cylinder 2 enters below the exhaust fan 51 through the filter screen 5 and the exhaust fan 51. At this time, the fan blade 53 is driven to rotate by the wind force, the fan blade 53 rotates to drive the rotating rod 52 to rotate, and at this time the reciprocating thread 54 rotates to drive the slider 55 to reciprocate up and down. At the same time, the slider 55 drives the extrusion plate 57 to move up and down. The humid air enters the inside of the moisture absorbent cotton 58, and the moisture is absorbed by the moisture absorbent cotton 58. When the moisture absorbent cotton 58 is saturated, the extrusion plate 57 squeezes the moisture absorbent cotton 58 during the descending process, so that the moisture inside the moisture absorbent cotton 58 flows out, and then the moisture flows out of the protection cylinder 2 through the drain hole 59, realizing the dehumidification function.

[0049] Please refer to Figure 6The inner wall of the protective tube 2 is provided with a disc-shaped cleaner 7, the outer wall of the cleaner 7 is provided with a plurality of gears 71, a through hole 72 is provided inside the cleaner 7, a No. 1 motor 73 is provided on the inner wall of the cleaner 7, a cleaning cotton cloth 74 is provided around the output end of the No. 1 motor 73, an arc-shaped cleaning plate 75 is provided on the inner wall of the cleaner 7, a cleaning brush 76 is provided on the outer wall of the cleaning plate 75, a dustproof plate 77 is provided on the inner wall of the cleaner 7, a plurality of guide wheels 78 are provided on the outer wall of the through hole 72, and the guide wheels 78 are connected to the output end of the No. 1 motor 73 through the cleaning cotton cloth 74, and the inner wall of the protective tube 2 is provided with a plurality of guide wheels 78. It is equipped with a No. 2 motor 8, and a reciprocating screw 81 is installed at the output end of the No. 2 motor 8. An adjusting block 82 is installed on the outer wall of the reciprocating screw 81 through threaded engagement. An adjusting rod 83 is installed on the outer wall of the adjusting block 82, and one end of the adjusting rod 83 is fixedly connected to the outer wall of the sensor probe 47. A driving rod is fixedly installed on the top of the reciprocating screw 81, and a driving gear 85 is installed on the outer wall of the driving rod, and the driving gear 85 is meshed with the gear 71. A sliding rod 84 is installed on the inner top wall of the protective tube 2, and a sliding block is slidably installed on the outer wall of the sliding rod 84. A fixing rod is installed on the outer wall of the sliding block, and one end of the fixing rod is fixedly connected to the outer wall of the sensor probe 47.

[0050] Specifically, when the sensor probe 47 needs to be cleaned, the second motor 8 is started, the second motor 8 rotates to drive the reciprocating screw 81 to rotate, and the driving rod rotates synchronously, the driving rod drives the driving gear 85 to rotate, and the driving gear 85 drives the gear 71 to rotate, so that the cleaner 7 rotates, and the cleaner 7 cleans the outer wall of the sensor probe 47;

[0051] It should be noted that the reciprocating screw 81 drives the adjustment block 82 to rise and fall, the adjustment block 82 rises and falls, the adjustment block 82 drives the adjustment rod 83 to rise and fall, the adjustment rod 83 drives the sensor probe 47 to rise and fall, at this time, the sensor probe 47 is retracted into the inside of the protective tube 2, the probe part is located inside the cleaner 7, and the probe part is cleaned;

[0052] It should be noted that when cleaning the sensor, the first motor 73 drives the cleaning cotton cloth 74 to rotate, and the cleaning cotton cloth 74 circulates through the guide wheel 78. At this time, the cleaning cotton cloth 74 contacts the outer wall of the sensor, and the dust on the surface of the sensor is wiped clean by the rotation of the cleaning cotton cloth 74, so as to keep the sensor clean and tidy, and prevent dust from affecting the detection accuracy of the sensor;

[0053] It should be noted that the cleaning cotton cloth 74 rotates and passes through the dustproof plate 77, which can prevent the dust on the cleaning cotton cloth 74 from returning to the sensor surface. Then, when the cleaning cotton cloth 74 passes through the cleaning plate 75 and the cleaning brush 76, the cleaning brush 76 sweeps off the dust on the cleaning cotton cloth 74, keeping the cleaning cotton cloth 74 clean to facilitate cleaning the surface of the sensor.

[0054] Working principle: When installing this device, multiple mounting bolts 12 are installed at the predetermined positions of the roadheader. The rubber pad 13 can weaken the impact of the vibration of the roadheader on the sensor, realizing the shock absorption function. When cleaning the sensor probe 47, the sensor probe 47 moves up and down. At this time, the outer wall of the sensor probe 47 drives the friction wheel 23 to rotate through friction. The rotation of the friction wheel 23 then drives the driven wheel 24 to rotate through the connecting belt 25. The driven wheel 24 drives multiple transmission shafts 31 to rotate through the belt 34. The transmission shafts 31 drive the cleaning wheels 32 and the first brush 33 to rotate, so that the sensor probe 47 can be cleaned by the cleaning wheels 32 and the first brush 33 during the up and down movement, and the dust and debris attached to the outer wall of the sensor probe 47 are cleaned off, keeping the sensor clean and tidy. Subsequently, when the sensor probe 47 needs to be cleaned, the second motor 8 is started. The rotation of the second motor 8 drives the reciprocating lead screw 81 to rotate, and at the same time the driving rod rotates synchronously. The driving rod drives the driving gear 85 to rotate. The driving gear 85 drives the gear 71 to rotate, so that the cleaner 7 rotates. The cleaner 7 cleans the outer wall of the sensor probe 47. The cleaning cloth 74 rotates past the dust-proof plate 77. The dust-proof plate 77 can prevent the dust on the cleaning cloth 74 from returning to the sensor surface. Subsequently, when the cleaning cloth 74 passes through the cleaning plate 75 and the cleaning brush 76, the cleaning brush 76 sweeps the dust on the cleaning cloth 74 off, keeping the cleaning cloth 74 clean for cleaning the surface of the sensor. Finally, the sealing plate 43 descends to squeeze the damping liquid stored inside the limiting cylinder 41. The damping liquid flows out from the connecting hole 61 and then enters the interior of the buffer cavity 6. Since the aperture of the connecting hole 61 is small, when the vibration amplitude is large, the downward pressure of the sealing plate 43 is large. At this time, a large amount of damping liquid needs to flow out, and it takes a longer time for the damping liquid to flow out due to the small aperture of the connecting hole 61, so as to utilize the flow difference of the damping liquid for the first buffering to protect the sensor. When the damping liquid enters the interior of the buffer cavity 6, the liquid level of the damping liquid rises to reach the height of the blocking block 62, and then the damping liquid flows upward from the pressure relief hole 63 and enters above the blocking block 62. Similarly, the pressure relief hole 63 is used for secondary buffering to effectively protect the sensor.
