The automatic inspection robot replaces manual inspections, and the rail-mounted inspection replaces the ground-walking inspection. This not only reduces the danger level and labor costs of manual inspections, and reduces the labor intensity of workers, but also increases the practical performance of the inspection robot, enabling it to quickly and stably reach any position in the mine, thereby achieving more comprehensive data collection and improving the safety performance of mine workers.

[0015] A patrol inspection method for a gold mine underground patrol inspection device, comprising the following steps:

[0016] S1. The cavity guide rail is fixedly installed on the top of the mine tunnel of the mine, and the movable outer frame is slidably installed on the periphery of the cavity guide rail through the groove;

[0017] S2. The output shaft of the power motor drives the external spline shaft to rotate. The rotation of the external spline shaft drives the internal spline shaft and the transmission vertical shaft to rotate around the inside of the sinking slider through the sliding plug-in effect with the internal spline shaft. The rotation of the transmission vertical shaft drives the driving gear to rotate, and the driving gear is meshed with the rack. Therefore, the driving gear rotates and rolls along the rack, causing the moving outer frame to move along the cavity guide rail. During the movement of the moving outer frame, the oxygen content in the mine tunnel is continuously collected through the oxygen sensor, and the collected oxygen content data is fed back to the PLC controller for information analysis;

[0018] S3. When the oxygen sensor detects that the oxygen content somewhere inside the mine tunnel is thin, the PLC controller receives the thin air signal transmitted by the oxygen sensor and issues a command to start the position sensor and the power motor continues to rotate, so the moving frame continues to move, carrying the position sensor with it. When the position sensor moves to the end of one of the telescopic rods, the position sensor monitors the position of the telescopic rod and immediately transmits a signal to the PLC controller. The PLC controller instructs the power motor to turn off and start the servo cylinder, which pushes the push plate together with the push column and the position sensor to the air through the output rod of the servo cylinder. The position sensor moves in the direction of the cavity guide rail. When the end of the position sensor contacts the end of the telescopic rod, the position sensor continues to push the telescopic rod to move along the telescopic hole toward the inside of the cavity guide rail under the action of the output rod of the servo cylinder. The movement of the telescopic rod drives the airtight plate to move together. The top spring is compressed and stores force, and the movement of the airtight plate causes a gap to be generated between the airtight plate and the inner wall of the cavity guide rail, so that the air inside the cavity guide rail enters the interior of the air distribution hole through the gap between the airtight plate and the inner wall of the cavity guide rail, and is discharged into the interior of the movable outer frame through the air distribution hole, and finally is discharged through the two vents opened on the movable outer frame, so as to replenish air to the thin air inside the mine tunnel.

[0019] S4. When the servo cylinder pushes the push plate to move in the direction of the cavity guide rail, the push plate also drives the positioning pin to move together through the connecting plate. Under the action of the wedge force between the positioning pin and the path bevel, the lifting ear and the sinking slider slide downward along the connection with the cantilever frame. The sinking slider slides downward and drives the internal spline sleeve shaft, the driving gear and the pressure plate to move downward through the transmission vertical shaft. When the trunk rod of the servo cylinder pushes the push plate to the final position, the bottom of the pressure plate just abuts against the top of the pressure plate, and the driving gear moves downward to separate from the rack. In addition to meshing, the output rod power of the power motor continues to be transmitted to the transmission vertical shaft through the plug-in effect of the external spline plug shaft and the internal spline sleeve shaft. The rotation of the transmission vertical shaft further drives the driven vertical shaft together with the active bevel gear to rotate through the abutment transmission effect of the pressure plate and the pressure plate. The rotation of the active bevel gear drives the horizontal main shaft to rotate around the two left and right bearing seats through the meshing effect with the driven bevel gear. The rotation of the horizontal main shaft drives the two output bevel shafts together with the two blades to rotate through the two left and right universal drive joints, so that the air sent by the two output bevel shafts can be blown farther.

[0020] S5. At the same time, the oxygen sensor continuously monitors the oxygen in the mine tunnel of the mobile outer frame attachment. When the air is replenished, the oxygen sensor detects that the oxygen content in the mine tunnel meets the standard, and transmits the monitoring data to the PLC controller. The PLC controller sends a command to the servo cylinder, and the output rod of the servo cylinder drives the push plate to move away from the cavity guide rail. The push plate drives the position sensor to move together through the push column, gradually releasing the push on the telescopic rod. The rebound force of the top spring is released to push the airtight plate and the telescopic rod to reset, causing the airtight plate to fit tightly against the inner wall of the cavity guide rail to block the air holes. During this period, the push plate also drives the connecting plate The locating pin moves together, so that under the action of the wedge force of the locating pin and the path inclined groove, the lifting ear and the settlement slide block are pushed upward, and the settlement slide block moves upward, driving the transmission vertical shaft, the driving gear and the pressure plate to move upward, and the driving gear meshes with the rack again, driving the moving outer frame to continue to move along the outer wall of the cavity guide rail to inspect the remaining mine tunnels in the mine, and the pressure plate moves upward and separates from the pressure plate. Therefore, the torque of the pressure plate can no longer be transmitted to the pressure plate, and the pressure plate stops rotating, and the two blades also stop rotating, so that the blades will not rotate continuously, so that when the moving outer frame moves along the cavity guide rail, the blades will not share the power of the power motor.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, the inspection component moves along the cavity guide rail to inspect the mine, and the oxygen sensor continuously collects the oxygen content in the mine tunnel. When the oxygen content somewhere inside the mine tunnel is thin, the PLC controller receives the thin air signal transmitted by the oxygen sensor and makes an instruction to start the position sensor, and the power motor continues to rotate, so that the moving outer frame continues to move, carrying the position sensor together. When the position sensor moves to the end of one of the telescopic rods, the position sensor monitors the position of the telescopic rod and immediately transmits a signal to the PLC controller. The PLC controller instructs the power motor to turn off and start the servo cylinder, and the output rod of the servo cylinder pushes The movable push plate, together with the push column and the position sensor, moves toward the direction close to the cavity guide rail. When the end of the position sensor abuts against the end of the telescopic rod, the position sensor continues to push the telescopic rod along the telescopic hole toward the inside of the cavity guide rail under the action of the output rod of the servo cylinder. The movement of the telescopic rod drives the airtight plate to move together, and the top spring is compressed and accumulates force. The movement of the airtight plate causes a gap to be generated between the airtight plate and the inner wall of the cavity guide rail, so that the air inside the cavity guide rail enters the interior of the air distribution hole through the gap between the airtight plate and the inner wall of the cavity guide rail, and is discharged into the interior of the movable outer frame through the air distribution hole, and is finally discharged through the two vents opened on the movable outer frame to replenish air to the thin air inside the mine tunnel.

[0023] 2. In the present invention, when the push plate is pushed to move in the direction of the cavity guide rail by the servo cylinder, the push plate also drives the positioning pin to move together through the connecting plate. Under the action of the wedge force between the positioning pin and the path inclined groove, the lifting ear and the sinking slider are pushed to slide downward along the connection with the cantilever frame. The sinking slider slides downward and drives the internal spline sleeve shaft, the driving gear and the pressure plate to move downward through the transmission vertical shaft. When the trunk rod of the servo cylinder pushes the push plate to the final position, the bottom of the pressure plate just abuts against the top of the pressure plate, and the driving gear moves downward to separate from the rack and release the meshing. Therefore, The output rod power of the power motor continues to be transmitted to the transmission vertical shaft through the plug-in action of the external spline plug-in shaft and the internal spline sleeve shaft. The rotation of the transmission vertical shaft further drives the driven vertical shaft together with the active bevel gear to rotate through the abutment transmission action of the pressure plate and the pressure plate. The rotation of the active bevel gear drives the horizontal main shaft to rotate around the two left and right bearing seats through the meshing action with the driven bevel gear. The rotation of the horizontal main shaft drives the two output bevel shafts together with the two blades to rotate through the two left and right universal drive joints, so that the air delivered by the two output bevel shafts is blown farther and faster, so that the range of air replenishment is wider and the efficiency is higher.

[0024] 3. In the present invention, when the push plate is pushed to move in the direction of the cavity guide rail by the servo cylinder, the push plate also drives the brake rod and the brake disc to move together until the brake disc abuts against the side of the cavity guide rail. The push plate continues to move, and the brake rod will slide relatively along the inner wall of the guide hole, causing the spring to stretch and accumulate force, and the rebound force of the spring acts on the brake rod, so that the brake disc is tightly attached to the side of the cavity guide rail, thereby playing a braking role, avoiding relative movement between the moving outer frame and the cavity guide rail, and ensuring the stability of the moving outer frame.

The rotation of the transmission vertical shaft 207 further drives the driven vertical shaft 2011 together with the active bevel gear 2013 to rotate through the abutment transmission action of the pressure plate 209 and the pressure plate 2012. The rotation of the active bevel gear 2013 drives the horizontal main shaft 2015 to rotate around the two left and right bearing seats 2014 through the meshing action with the driven bevel gear 2016. The rotation of the horizontal main shaft 2015 drives the two output oblique shafts 2017 together with the two blades 2018 to rotate through the two left and right universal drive joints, so that the air sent by the two output oblique shafts 2017 is blown farther and faster, so that the range of air replenishment is wider and the efficiency is higher.

[0051] Embodiment 4:

[0052] A side surface of the push plate 302 close to the servo cylinder 301 is penetrated with two guide holes 309 distributed front and back, the two guide holes 309 are located between the two push columns 303, and brake rods 3010 are slidably installed inside the two guide holes 309, a brake disc 3011 is fixedly installed on one end of the brake rod 3010 close to the cavity guide rail 1, a nut 3012 is threadedly connected to the outer wall of the end of the brake rod 3010 away from the brake disc 3011, and a spring 3013 is sleeved on the outer periphery of the brake rod 3010, and the spring 3013 is fixedly installed between the push plate 302 and the nut 3012;

[0053] Specifically, in this embodiment, when the servo cylinder 301 pushes the push plate 302 to move in the direction of the cavity guide rail 1, the push plate 302 also drives the brake rod 3010 and the brake disc 3011 to move together, until the brake disc 3011 abuts against the side of the cavity guide rail 1, the push plate 302 continues to move, and the brake rod 3010 will slide relatively along the inner wall of the guide hole 309, causing the spring 3013 to stretch and accumulate force, and the rebound force of the spring 3013 acts on the brake rod 3010, so that the brake disc 3011 is tightly attached to the side of the cavity guide rail 1, thereby playing a braking role, avoiding relative movement between the moving outer frame 201 and the cavity guide rail 1, and ensuring the stability of the moving outer frame 201.

[0054] A patrol inspection method for a gold mine underground patrol inspection device, comprising the following steps:

[0055] S1, the cavity guide rail 1 is fixedly installed on the top of the mine tunnel, and the movable outer frame 201 is slidably installed on the periphery of the cavity guide rail 1 through the groove 202;

[0056] S2. The output shaft of the power motor 2021 drives the external spline shaft 2020 to rotate. The rotation of the external spline shaft 2020 drives the internal spline shaft 2019 and the transmission vertical shaft 207 to rotate around the inside of the sedimentation slider 206 through the sliding plug-in effect with the internal spline shaft 2019. The rotation of the transmission vertical shaft 207 drives the driving gear 2022 to rotate, and the driving gear 2022 is meshed with the rack 208. Therefore, the driving gear 2022 rotates and rolls along the rack 208, causing the moving outer frame 201 to move along the cavity guide rail 1. During the movement of the moving outer frame 201, the oxygen content in the mine tunnel is continuously collected by the oxygen sensor 4, and the collected oxygen content data is fed back to the PLC controller 5 for information analysis;

[0057] S3. When the oxygen sensor 4 detects that the oxygen content somewhere inside the mine tunnel is thin, the PLC controller 5 receives the thin air signal transmitted by the oxygen sensor 4 and issues an instruction to start the position sensor 304, and the power motor 2021 continues to rotate, so that the mobile outer frame 201 continues to move, carrying the position sensor 304 with it. When the position sensor 304 moves to the end of one of the telescopic rods 103, the position sensor 304 monitors the position of the telescopic rod 103 and immediately transmits a signal to the PLC controller 5. The PLC controller 5 instructs the power motor 2021 to turn off and start the servo cylinder 301. The output rod of the servo cylinder 301 pushes the push plate 302 together with the push column 303 and the position sensor 304 to the cavity guide. The position sensor 304 moves in the direction of the cavity guide rail 1. When the end of the position sensor 304 contacts the end of the telescopic rod 103, the position sensor 304 continues to push the telescopic rod 103 to move along the telescopic hole 101 toward the inside of the cavity guide rail 1 under the action of the output rod of the servo cylinder 301. The movement of the telescopic rod 103 drives the airtight plate 104 to move together, and the top spring 105 is compressed and stores force. The movement of the airtight plate 104 causes a gap to be generated between the airtight plate 104 and the inner wall of the cavity guide rail 1, so that the air inside the cavity guide rail 1 enters the interior of the air distribution hole 102 through the gap between the airtight plate 104 and the inner wall of the cavity guide rail 1, and is discharged into the interior of the movable outer frame 201 through the air distribution hole 102, and is finally discharged through the two vents 203 opened on the movable outer frame 201, so as to replenish air to the thin air inside the mine tunnel.

[0058] S4. When the servo cylinder 301 pushes the push plate 302 to move in the direction of the cavity guide rail 1, the push plate 302 also drives the positioning pin 306 to move together through the connecting plate 305. Under the action of the wedge force between the positioning pin 306 and the path bevel groove 308, the lifting ear 307 is pushed together with the sinking slider 206 to slide downward along the connection with the cantilever frame 205. The sinking slider 206 slides downward and drives the inner spline sleeve shaft 2019, the driving gear 2022 and the pressure plate 209 to move downward through the transmission vertical shaft 207. When the trunk rod of the servo cylinder 301 pushes the push plate 302 to the final position, the bottom of the pressure plate 209 just abuts against the top of the pressure plate 2012, and the driving gear 2022 moves downward to separate and disengage from the rack 208. Therefore, the power The output rod power of the motor 2021 is continuously transmitted to the transmission vertical shaft 207 through the plug-in effect of the external spline plug shaft 2020 and the internal spline sleeve shaft 2019. The rotation of the transmission vertical shaft 207 further drives the driven vertical shaft 2011 together with the active bevel gear 2013 to rotate through the abutment transmission effect of the pressure plate 209 and the pressure plate 2012. The active bevel gear 2013 rotates through the meshing effect with the driven bevel gear 2016 to drive the horizontal main shaft 2015 to rotate around the two left and right bearing seats 2014. The rotation of the horizontal main shaft 2015 drives the two output oblique shafts 2017 together with the two blades 2018 to rotate through the two left and right universal drive joints, so that the air sent by the two output oblique shafts 2017 is blown farther and faster, so that the range of air replenishment is wider and the efficiency is higher.

[0059] S5. At the same time, the oxygen sensor 4 continuously monitors the oxygen in the mine tunnel near the moving outer frame 201. When the air is replenished, the oxygen sensor 4 detects that the oxygen content in the mine tunnel meets the standard and transmits the monitoring data to the PLC controller 5. The PLC controller 5 sends a command to the servo cylinder 301. The output rod of the servo cylinder 301 drives the push plate 302 to move away from the cavity guide rail 1. The push plate 302 drives the position sensor 304 to move together through the push column 303, gradually releasing the push on the telescopic rod 103. The rebound force of the top spring 105 is released to push the airtight plate 104 and the telescopic rod 103 to reset, causing the airtight plate 104 to be tightly attached to the inner wall of the cavity guide rail 1, and the air distribution hole 102 is blocked. During this period, the push plate 302 also drives the positioning pin 306 to move together through the connecting plate 305, so that under the wedge force of the positioning pin 306 and the path inclined groove 308, the lifting ear 307 and the sinking slider 206 are pushed upward The driving gear 2022 meshes with the rack 208 again, driving the movable outer frame 201 to continue to move along the outer wall of the cavity guide rail 1 to inspect the remaining mine tunnels in the mine, while the pressure plate 209 moves up and separates from the pressure plate 2012. Therefore, the torque of the pressure plate 209 can no longer be transmitted to the pressure plate 2012, and the pressure plate 2012 stops rotating. The two blades 2018 also stop rotating, so that the blades 2018 will not rotate all the time, so that the movable outer frame 201 will not share the power of the power motor 221 during the movement of the cavity guide rail 1. On the one hand, the load of the power motor 2021 can be reduced and the service life of the power motor 2021 can be increased. On the other hand, since the load of the power motor 2021 is small, the loss of electric energy can be saved, which is beneficial to controlling the cost of use.

[0060] In the present scheme, when the underground inspection device of a gold mine is working, the cavity guide rail 1 is fixedly installed on the top of the mine tunnel of the mine, and the movable outer frame 201 is slidably installed on the periphery of the cavity guide rail 1 through the groove 202, and the cavity guide rail 1 can be extended and arranged on the top of the mine tunnel in a head-to-tail connection manner, and the starting end of the cavity guide rail 1 is connected to the output end of the external high-pressure fan through a pipeline, and the external high-pressure fan continuously transports air to the inside of the cavity guide rail 1 through the pipeline;

[0061] The output shaft of the power motor 2021 drives the external spline shaft 2020 to rotate. The rotation of the external spline shaft 2020 drives the internal spline shaft 2019 and the transmission vertical shaft 207 to rotate around the inside of the sedimentation slider 206 through the sliding plug-in effect with the internal spline shaft 2019. The rotation of the transmission vertical shaft 207 drives the driving gear 2022 to rotate, and the driving gear 2022 is engaged with the rack 208. Therefore, the driving gear 2022 rotates and rolls along the rack 208, causing the moving outer frame 201 to move along the cavity guide rail 1. During the movement of the moving outer frame 201, the oxygen content in the mine tunnel is continuously collected by the oxygen sensor 4, and the collected oxygen content data is fed back to the PLC controller 5 for information analysis;

[0062] When the oxygen sensor 4 detects that the oxygen content somewhere inside the mine tunnel is thin, the PLC controller 5 receives the thin air signal transmitted by the oxygen sensor 4 and issues an instruction to start the position sensor 304, and the power motor 2021 continues to rotate, so that the moving outer frame 201 continues to move, carrying the position sensor 304 with it. When the position sensor 304 moves to the end of one of the telescopic rods 103, the position sensor 304 monitors the position of the telescopic rod 103 and immediately transmits a signal to the PLC controller 5. The PLC controller 5 instructs the power motor 2021 to turn off and start the servo cylinder 301. The output rod of the servo cylinder 301 pushes the push plate 302 together with the push column 303 and the position sensor 304 to approach the cavity guide rail 1. When the end of the position sensor 304 contacts the end of the telescopic rod 103, the position sensor 304 continues to push the telescopic rod 103 along the telescopic hole 101 to move toward the inside of the cavity guide rail 1 under the action of the output rod of the servo cylinder 301. The movement of the telescopic rod 103 drives the airtight plate 104 to move together, and the top spring 105 is compressed and stores force. The movement of the airtight plate 104 causes a gap to be generated between the airtight plate 104 and the inner wall of the cavity guide rail 1, so that the air inside the cavity guide rail 1 enters the interior of the air distribution hole 102 through the gap between the airtight plate 104 and the inner wall of the cavity guide rail 1, and is discharged into the interior of the movable outer frame 201 through the air distribution hole 102, and is finally discharged through the two vents 203 opened on the movable outer frame 201, so as to replenish air to the thin air inside the mine tunnel;

[0063] When the servo cylinder 301 pushes the push plate 302 to move in the direction of the cavity guide rail 1, the push plate 302 also drives the positioning pin 306 to move together through the connecting plate 305. Under the action of the wedge force between the positioning pin 306 and the path bevel groove 308, the lifting ear 307 is pushed together with the sinking slider 206 to slide downward along the connection with the cantilever frame 205. The sinking slider 206 slides downward and drives the internal spline sleeve shaft 2019, the driving gear 2022 and the pressure plate 209 to move downward through the transmission vertical shaft 207. When the trunk rod of the servo cylinder 301 pushes the push plate 302 to the final position, the bottom of the pressure plate 209 just abuts against the top of the pressure plate 2012, and the driving gear 2022 moves downward to separate and disengage from the rack 208. Therefore, the power electric The output rod power of the machine 2021 is continuously transmitted to the transmission vertical shaft 207 through the plug-in effect of the external spline plug shaft 2020 and the internal spline sleeve shaft 2019. The rotation of the transmission vertical shaft 207 further drives the driven vertical shaft 2011 together with the active bevel gear 2013 to rotate through the abutment transmission effect of the pressure plate 209 and the pressure plate 2012. The active bevel gear 2013 rotates through the meshing effect with the driven bevel gear 2016 to drive the horizontal main shaft 2015 to rotate around the two left and right bearing seats 2014. The rotation of the horizontal main shaft 2015 drives the two output oblique shafts 2017 together with the two blades 2018 to rotate through the two left and right universal drive joints, so that the air sent by the two output oblique shafts 2017 is blown farther and faster, so that the range of air replenishment is wider and the efficiency is higher.

[0064] At the same time, the oxygen sensor 4 continuously monitors the oxygen in the mine tunnel near the moving outer frame 201. When the air is replenished, the oxygen sensor 4 detects that the oxygen content in the mine tunnel meets the standard and transmits the monitoring data to the PLC controller 5. The PLC controller 5 sends a command to the servo cylinder 301. The output rod of the servo cylinder 301 drives the push plate 302 to move away from the cavity guide rail 1. The push plate 302 drives the position sensor 304 to move together through the push column 303, gradually releasing the push on the telescopic rod 103. The rebound force of the top spring 105 is released to push the airtight plate 104 and the telescopic rod 103 to reset, causing the airtight plate 104 to fit tightly against the inner wall of the cavity guide rail 1, and the air distribution hole 102 is blocked. During this period, the push plate 302 also drives the positioning pin 306 to move together through the connecting plate 305, so that under the wedge force of the positioning pin 306 and the path inclined groove 308, the lifting ear 307 and the sinking slider 206 are pushed upward The driving gear 2022 meshes with the rack 208 again, driving the movable outer frame 201 to continue to move along the outer wall of the cavity guide rail 1 to inspect the remaining mine tunnels in the mine, while the pressure plate 209 moves up and separates from the pressure plate 2012. Therefore, the torque of the pressure plate 209 can no longer be transmitted to the pressure plate 2012, and the pressure plate 2012 stops rotating. The two blades 2018 also stop rotating, so that the blades 2018 will not rotate all the time, so that the movable outer frame 201 will not share the power of the power motor 221 during the movement of the cavity guide rail 1.

When the trunk rod of the servo cylinder (301) pushes the push plate (302) to the final position, the bottom of the pressure plate (209) just abuts against the top of the pressure plate (212), and the driving gear (222) moves downward to abut against the rack (212). 08) is separated and disengaged, so the output rod power of the power motor (221) continues to be transmitted to the transmission vertical shaft (207) through the plug-in effect of the external spline plug shaft (2020) and the internal spline sleeve shaft (219), and the rotation of the transmission vertical shaft (207) further drives the driven vertical shaft (2011) and the active bevel gear (2013) to rotate through the abutment transmission effect of the pressure plate (209) and the pressure plate (2012), and the active bevel gear (2013) rotates through the meshing effect with the driven bevel gear (2016) to drive the horizontal main shaft (2015) to rotate around the two left and right bearing seats (2014), and the rotation of the horizontal main shaft (2015) drives the two output oblique shafts (2017) and the two blades (2018) to rotate through the two left and right universal drive joints, so that the air sent by the two output oblique shafts (2017) is blown farther; S5. At the same time, the oxygen sensor (4) continuously monitors the oxygen in the mine tunnel near the movable outer frame (201). When the air is replenished, the oxygen sensor (4) detects that the oxygen content in the mine tunnel at that location meets the standard, and transmits the monitoring data to the PLC controller (5). The PLC controller (5) issues a command to the servo cylinder (301). The output rod of the servo cylinder (301) drives the push plate (302) to move in a direction away from the cavity guide rail (1). The push plate (302) ) drives the position sensor (304) to move together through the push column (303), gradually releasing the push on the telescopic rod (103), and the rebound force of the top spring (105) is released to push the airtight plate (104) and the telescopic rod (103) to reset, so that the airtight plate (104) and the inner wall of the cavity guide rail (1) are tightly attached to each other, and the air distribution hole (102) is blocked. During this period, the push plate (302) also drives the positioning pin (306) to move together through the connecting plate (305), so that Under the action of the wedge force of the positioning pin (306) and the path inclined groove (308), the lifting lug (307) and the sinking slider (206) are pushed upward, and the sinking slider (206) moves upward to drive the transmission vertical shaft (207), the driving gear (2022) and the pressure plate (209) to move upward, and the driving gear (2022) meshes with the rack (208) again, driving the moving outer frame (201) to continue to move along the outer wall of the cavity guide rail (1), so as to inspect the remaining mine tunnels in the mine. , and the pressure plate (209) moves upward and separates from the pressure plate (2012), so that the torque of the pressure plate (209) can no longer be transmitted to the pressure plate (2012), the pressure plate (2012) stops rotating, and the two blades (218) also stop rotating, so that the blades (2018) will not rotate continuously, so that when the movable outer frame (201) moves along the cavity guide rail (1), the blades (2018) will not share the power of the power motor (221).
