Description

Technical Field

[0001] This invention relates to the field of inclinometer technology, and particularly to an automated inclinometer. Background Technology

[0002] Inclinometers are mainly used to measure the tilt angle and displacement changes of engineering structures such as boreholes, foundation pits, and slopes. They are used in multiple fields such as geological monitoring, geotechnical engineering, and oil exploration. In the specific detection process, holes are drilled at the detection site in advance, and pipes are installed in the detection holes. Finally, the detection tube of the inclinometer is placed into the pipes to carry out the detection work. The size of the detection hole is related to the geology of the detection site. If the geology is prone to collapse, a thicker inclinometer tube may be needed.

[0003] Chinese invention patent CN117308884B discloses an automated inclinometer, including an inclinometer rod, an integrated control panel, and a cable winding mechanism. The inclinometer rod is connected to the integrated control panel via a cable. Measurement points are evenly spaced on the cable. The integrated control panel is connected to a first sensor for detecting the measurement points. The invention is characterized by further including a housing and a buffer compensation assembly. A first support and a second support are arranged at the front and rear of the housing. A first guide wheel and a second guide wheel are rotatably mounted on the first and second support, respectively. The buffer compensation assembly includes a counterweight, a pulley connected to the counterweight, and a locking device located on the first support for locking the cable and the first guide wheel.

[0004] The existing technology does not have an adjustable limiting structure. The outer diameter of the detection tube is fixed, and it cannot adjust the fit with the inner wall of the pipe in real time according to the inner diameter of the protected pipe. When there is a gap between the detection tube and the inner wall of the pipe (especially in large-diameter protected pipes), the detection tube is prone to tilting or shaking in the pipe, which causes the angle data collected by the tilt sensor to be distorted, directly reducing the measurement accuracy. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an automated inclinometer.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automated inclinometer, comprising an inclinometer body, a controller disposed on the inclinometer body, and movable wheels disposed at the bottom of the inclinometer body. The controller is provided with a display screen. The inclinometer body is provided with a cable electrically connected to the controller. A detection tube is detachably connected to the cable. An inclination sensor electrically connected to the cable is disposed inside the detection tube. Multiple mounting brackets are uniformly distributed about the axis of the detection tube and are slidably engaged with the detection tube. A pressure sensor is disposed on the mounting bracket. Each mounting bracket is rotatably mounted with a roller. A displacement component is provided on the detection tube for driving the multiple mounting brackets to move closer or further apart.

[0007] By adopting the above technical solution, the operator first inserts the detection tube into the pipe to be tested. Then, the displacement component is operated to drive multiple mounting brackets away from each other, which in turn drives multiple rollers to move away from each other until the pressure sensor on the mounting bracket detects a predetermined value. At this point, all the rollers are in contact with the inner wall of the pipe, limiting the detection tube inside the pipe. This avoids the detection tube tilting due to the gap between the detection tube and the pipe, improving measurement accuracy. In addition, controlling the distance between the multiple rollers can adapt to pipes and holes of various inner diameters, expanding the scope of application. During specific testing, the tilt sensor inside the detection tube detects the degree of tilt of the pipe and the detection hole, converting the physical quantity of "tilt angle" into electrical signals such as voltage, current, or digital signals, which are then transmitted to the cable and then to the controller for real-time observation and judgment.

[0008] Furthermore, the displacement assembly includes a conduit fixed inside the detection tube and coaxially arranged with the detection tube, an adjusting disc rotatably sleeved on the conduit, an adjusting column rotatably mounted on the mounting bracket, a first motor fixed on the conduit, an adjusting gear fixedly sleeved on the output end of the first motor, and an arc-shaped rack fixed on the adjusting disc and coaxially arranged with the adjusting disc. The adjusting disc has an adjusting through hole eccentrically arranged with respect to the adjusting disc. The adjusting column is slidably engaged with the adjusting through hole. The number of adjusting through holes, the number of adjusting columns, and the number of mounting brackets are all equal and their positions correspond one-to-one. The arc-shaped rack meshes with the adjusting gear.

[0009] By adopting the above technical solution, when the first motor is working, it drives the adjusting gear to rotate, which in turn drives the arc rack meshing with the adjusting gear and the adjusting plate fixed to the arc rack to rotate synchronously. Since the adjusting column and the adjusting through hole are in sliding fit, and the adjusting through hole and the adjusting plate are eccentrically set, the adjusting column, the mounting bracket connected to the adjusting column and the roller connected to the mounting bracket all move closer to or further away from each other to ensure that the detection tube is limited.

[0010] Furthermore, the detection tube is provided with a driving mechanism, which includes a driving assembly. The driving assembly includes a first bevel gear fixedly sleeved on the roller, a sleeve that passes through the mounting bracket and is rotatably connected to the mounting bracket, a second bevel gear fixedly sleeved on the sleeve, a driving rod that is slidably disposed in the sleeve, and a limiting block fixed on the driving rod. The sleeve is provided with a limiting through hole that slidably engages with the limiting block. The number of limiting through holes, the number of driving assembly groups, and the number of rollers are all equal and their positions correspond one-to-one. The driving mechanism also includes a rotating assembly for driving multiple driving rods to rotate synchronously.

[0011] By adopting the above technical solution, the rotating component drives multiple drive rods to rotate synchronously, thereby driving the limiting block fixed to the drive rod, the sleeve that slides with the limiting block through the limiting hole, the second bevel gear fixed to the sleeve, the first bevel gear meshing with the second bevel gear, and the roller fixed to the first bevel gear to rotate. By using the different rotation directions of the rollers, the detection tube can be made to move automatically in the pipeline, making it smoother when the detection tube enters or exits the pipeline.

[0012] Furthermore, the rotating assembly includes a third bevel gear fixedly sleeved on the drive rod, a fourth bevel gear rotatably sleeved on the conduit and meshing with the third bevel gear, a driven gear fixed on the fourth bevel gear and coaxially arranged with the fourth bevel gear, a second motor fixed on the conduit, and a driving gear fixedly sleeved on the output end of the second motor and meshing with the driven gear.

[0013] By adopting the above technical solution, when the second motor is working, it drives the driving gear to rotate, which in turn drives the driven gear meshing with the driving gear, the fourth bevel gear fixed with the driven gear, the third bevel gear meshing with the fourth bevel gear, and the drive rod fixed with the third bevel gear to rotate, so as to ensure the normal rotation operation of the roller.

[0014] Furthermore, the inclinometer body is provided with a winding mechanism, which includes a winding assembly and a transmission assembly. The winding assembly includes a mounting plate fixed to the inclinometer body, a winding wheel rotatably mounted on the mounting plate, a third motor fixed to the mounting plate and driving the winding wheel to rotate, a reciprocating screw rotatably mounted on the mounting plate, a crossbar fixedly mounted on the mounting plate, a mounting block threadedly connected to the reciprocating screw, and a pulley rotatably sleeved on the crossbar. The detection tube is wound around the winding wheel, and the side wall of the detection tube passes through the groove of the pulley and engages with it. The crossbar passes through the mounting block and engages with it slidably. The transmission assembly includes a drive shaft fixed to and coaxially arranged on the take-up reel, two sprockets respectively fixedly sleeved on the drive shaft and the reciprocating screw, and a chain for connecting the two sprockets, wherein the chain meshes with the two sprockets.

[0015] By adopting the above technical solution, when the third motor is working, it drives the winding wheel to rotate, which can perform winding or unwinding operations on the cable, so that the whole device can be carried. In addition, during the rotation of the winding wheel, the drive shaft fixed to the winding wheel, one of the sprockets fixed to the drive shaft, the chain meshing with the sprocket, the other sprocket meshing with the chain, and the reciprocating screw fixed to the other sprocket all rotate. Under the limit of the crossbar, the mounting block drives the pulley to reciprocate along the axis of the reciprocating screw, so that the cable can be evenly wound on the winding wheel.

[0016] Furthermore, the detection tubes are provided in multiple ways. A mounting column is fixed on the main body of the inclinometer. An annular block is fitted on the mounting column. An electric gripper for fixing the detection tube is fixed on the annular block. The number of electric grippers is equal to the number of detection tubes and their positions correspond one-to-one. The outer diameter of each detection tube is different. The size of the electric gripper is adapted to the size of the corresponding detection tube. A rotating mechanism for driving the annular block to rotate is provided on the mounting column.

[0017] By adopting the above technical solution, since there are multiple detection tubes and each detection tube has a different outer diameter, the detection tubes are first disconnected from the cable. Then, the rotating mechanism is operated to drive the ring block to rotate, rotating the other detection tubes to the position of the cable and fixing them. The detection work can then be carried out through the other detection tubes. When the diameter of the detection hole is much larger than that of one of the detection tubes, the rotating mechanism can be operated to select other suitable detection tubes to complete the detection operation, thus expanding the applicability of the device.

[0018] Furthermore, the rotating mechanism includes a rotating assembly, which includes an electric push rod fixed to a mounting column, an annular rotating plate rotatably mounted on an annular block and coaxially arranged with the annular block, multiple limiting posts slidably arranged on the annular block, and ball bearings movably mounted on the limiting posts. The side wall of the mounting column has inclined grooves that slide with the limiting posts, and vertical grooves are also formed on the side wall of the mounting column. The number of limiting posts, inclined grooves, and vertical grooves are all equal and their positions correspond one-to-one. Multiple inclined grooves and multiple vertical grooves are alternately arranged. The upper end of each vertical groove communicates with the upper end of one side of the inclined groove. The lower end of the vertical groove is connected to the lower end of the inclined groove on the other side. The side wall of the vertical groove near the axis of the mounting column is composed of an upper plane, an inclined surface, and a lower plane. The ball is in rolling connection with the lower plane of the vertical groove. The distance between the upper plane of the vertical groove and the axis of the mounting column is greater than the distance between the side wall of the inclined groove near the axis of the mounting column and the axis of the mounting column. The distance between the lower plane of the vertical groove and the axis of the mounting column is less than the distance between the side wall of the inclined groove near the axis of the mounting column and the axis of the mounting column. The distance between the inclined surface of the vertical groove and the axis of the mounting column gradually decreases from top to bottom. The rotating mechanism also includes a reset component for driving the limit post to reset.

[0019] By adopting the above technical solution, after the electric push rod operates, its push rod end retracts until the overall length of the electric push rod is at its minimum. This causes the annular rotating plate connected to the push rod end of the electric push rod, the annular block rotatably connected to the annular rotating plate, the limiting post connected to the annular block, and the ball connected to the limiting post to all rise. During this process, the ball moves from the vertical groove to the inclined groove. Similarly, after the electric push rod operates, its push rod end extends and returns to its original position, thereby causing the annular rotating plate connected to the push rod end of the electric push rod, the annular block rotatably connected to the annular rotating plate, and the ball connected to the limiting post to all rise. The block, the limiting post connected to the annular block, and the ball connected to the limiting post all descend and reset. During this process, since the distance between the upper plane of the vertical groove and the axis of the mounting post is greater than the distance between the side wall of the inclined groove near the axis of the mounting post and the axis of the mounting post, the vertical groove limits the limiting post. The limiting post drives the ball to move from the upper end of the inclined groove to the lower end of the inclined groove, thereby causing the annular block connected to the limiting post, the electric gripper connected to the annular block, and the detection tube connected to the electric gripper to rotate. The detection tube can be rotated to the bottom of the cable according to specific requirements.

[0020] Furthermore, a sliding through hole is provided through the top of the annular block, and the limiting post passes through the side wall of the sliding through hole and slides in fit. The reset assembly includes a sliding block that is slidably disposed in the sliding through hole and fixed to the limiting post, and a spring fixed between the sliding block and the inner side wall of the annular block. The number of reset assemblies, the number of sliding through holes, and the number of limiting posts are all equal and their positions correspond one-to-one.

[0021] By adopting the above technical solution, during the movement of the ball along the vertical groove, the ball first moves from the lower plane of the vertical groove to the inclined surface of the vertical groove, then from the inclined surface of the vertical groove to the upper plane of the vertical groove, and finally from the upper plane of the vertical groove into the inclined groove. During this process of the ball moving along the inclined surface of the vertical groove, since the distance between the inclined surface of the vertical groove and the axis of the mounting column gradually decreases from top to bottom, the ball is forced to move the limiting column away from the axis of the mounting column. The sliding block moves and causes the spring to contract. When the ball moves from the upper plane of the vertical groove into the inclined groove, since the distance between the upper plane of the vertical groove and the axis of the mounting column is greater than the distance between the side wall of the inclined groove near the axis of the mounting column and the axis of the mounting column, the spring gradually extends. The sliding block drives the limiting column and the ball to move towards the axis of the mounting column until the ball is in contact with the surface of the inclined groove, so as to ensure the normal movement of the limiting column.

[0022] Furthermore, a first plug is fixed to the top of the detection tube, and a second plug connected to the cable circuit is fixed to the cable. The first plug and the second plug are inserted into each other, and a threaded sleeve that is threadedly connected to the first plug is rotatably installed on the surface of the second plug.

[0023] By employing the above technical solution, rotating the threaded sleeve until it separates from the first plug, and then pulling the second plug upwards to separate it from the first plug, the operation of separating the cable and the detection tube can be completed. Similarly, by inserting the second plug into the first plug, and then threading the threaded sleeve into the first plug, the operation of connecting the cable and the detection tube can be completed.

[0024] Furthermore, a horizontal plate is fixed on the mounting plate, and a limiting through hole is provided through the horizontal plate for the cable to pass through. Two limiting wheels are rotatably installed in the limiting through hole, and the detection tube passes between the two limiting wheels. The side wall of the detection tube and the side walls of the two limiting wheels that are close to each other are in rolling contact.

[0025] By adopting the above technical solution and setting the limit wheel, the stability of the cable during release or rewind is improved.

[0026] In summary, the present invention has the following beneficial effects: In this application, by improving the existing technical structure, the situation of the detection tube tilting due to the gap between the detection tube and the pipe is avoided, thus improving the measurement accuracy. In addition, by controlling the distance between multiple rollers, it can adapt to pipes and holes of various inner diameters, thus expanding the scope of application. Attached Figure Description

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-8As shown in the illustration, this application discloses an automated inclinometer, including an inclinometer body 1, a displacement component 6, a drive mechanism 8, a winding mechanism 10, and a rotation mechanism 14. A controller with a display screen is mounted on the inclinometer body 1. Four movable wheels arranged in a rectangular array are located at the bottom of the inclinometer body 1. A cable 2, electrically connected to the controller, is mounted on the inclinometer body 1. A detection tube 3 is detachably connected to the cable 2, and an inclination sensor electrically connected to the cable 2 is located inside the detection tube 3. Multiple mounting brackets 4, evenly distributed about the axis of the detection tube 3, are threaded through the detection tube 3. The mounting brackets 4 slide against the detection tube 3, and pressure sensors are mounted on each mounting bracket 4. Each mounting bracket 4 has a rotatably mounted roller 5. First, the operator inserts the detection tube 3 into the pipe to be tested. Then, the operator operates the displacement component 6 to drive multiple mounting brackets 4 away from each other, which in turn drives multiple rollers 5 to move away from each other until the pressure sensor on the mounting bracket 4 detects a predetermined value. At this point, all rollers 5 are in contact with the corresponding inner wall of the pipe, limiting the movement of the detection tube 3 inside the pipe. This prevents the detection tube 3 from tilting due to the gap between it and the pipe, improving measurement accuracy. In addition, controlling the distance between the multiple rollers 5 allows for adaptation to pipes and holes of various inner diameters, expanding the applicability. During actual testing, the tilt sensor inside the detection tube 3 detects the degree of tilt of the pipe and the detection hole, converting the physical quantity of "tilt angle" into electrical signals such as voltage, current, or digital signals. These electrical signals are then transmitted to the cable 2, and from the cable 2, they are transmitted to the controller for real-time observation and judgment.

[0031] The displacement assembly 6 is mounted on the detection tube 3 and is used to drive multiple mounting brackets 4 to move closer or further apart. The displacement assembly 6 includes a conduit 61, an adjusting disc 62, an adjusting column 63, a first motor 64, an adjusting gear 65, and an arc-shaped rack 66. The conduit 61 is fixed inside the detection tube 3 and coaxially arranged with it. The adjusting disc 62 is rotatably mounted on the conduit 61, and an adjusting through hole 7 is eccentrically arranged on the adjusting disc 62. The adjusting column 63 is slidably engaged with the adjusting through hole 7 and is rotatably mounted on the mounting bracket 4. The number of adjusting through holes 7, the number of adjusting columns 63, and the number of mounting brackets 4 are all equal and their positions correspond one-to-one. The first motor 64 is fixed on the conduit 61, and the adjusting gear 65 is fixedly mounted on the output end of the first motor 64. The arc-shaped rack 66 is fixed on the adjusting disc 62 and coaxially arranged with it, and meshes with the adjusting gear 65. When the first motor 64 is working, it drives the adjusting gear 65 to rotate, which in turn drives the arc rack 66 meshing with the adjusting gear 65 and the adjusting disk 62 fixed to the arc rack 66 to rotate synchronously. Since the adjusting column 63 and the adjusting through hole 7 are in sliding fit, and the adjusting through hole 7 and the adjusting disk 62 are eccentrically set, the adjusting column 63, the mounting bracket 4 connected to the adjusting column 63 and the roller 5 connected to the mounting bracket 4 move closer or further away from each other to ensure that the detection tube 3 is limited.

[0032] The drive mechanism 8 is mounted on the detection tube 3 and includes a drive assembly 81 and a rotating assembly 82. The drive assembly 81 includes a first bevel gear 811, a sleeve 812, a second bevel gear 813, a drive rod 814, and a limiting block 815. The first bevel gear 811 is fixedly sleeved on the roller 5. The sleeve 812 is rotatably connected to the mounting bracket 4 and has a limiting through hole 9 that slides with the limiting block 815. The number of limiting through holes 9, the number of drive assemblies 81, and the number of rollers 5 are all equal and their positions correspond one-to-one. The second bevel gear 813 is fixedly sleeved on the sleeve 812. The drive rod 814 is slidably disposed inside the sleeve 812, and the limiting block 815 is fixed to the drive rod 814. The rotating assembly 82 drives multiple drive rods 814 to rotate synchronously, which in turn drives the limiting block 815 fixed to the drive rod 814, the sleeve 812 that slides with the limiting block 815 through the limiting through hole 9, the second bevel gear 813 fixed to the sleeve 812, the first bevel gear 811 meshing with the second bevel gear 813, and the roller 5 fixed to the first bevel gear 811 to rotate. By using the different rotation directions of the roller 5, the detection tube 3 can move automatically in the pipe, making it smoother when the detection tube 3 enters or exits the pipe.

[0033] The rotating assembly 82 is used to drive multiple drive rods 814 to rotate synchronously. The rotating assembly 82 includes a third bevel gear 821, a fourth bevel gear 822, a driven gear 823, a second motor 824, and a driving gear 825. The third bevel gear 821 is fixedly sleeved on the drive rod 814, and the fourth bevel gear 822 is rotatably sleeved on the conduit 61 and meshes with the third bevel gear 821. The driven gear 823 is fixed on the fourth bevel gear 822 and coaxially arranged with the fourth bevel gear 822. The second motor 824 is fixed on the conduit 61, and the driving gear 825 is fixedly sleeved on the output end of the second motor 824 and meshes with the driven gear 823. When the second motor 824 is working, it drives the drive gear 825 to rotate, which in turn drives the driven gear 823 meshing with the drive gear 825, the fourth bevel gear 822 fixed with the driven gear 823, the third bevel gear 821 meshing with the fourth bevel gear 822, and the drive rod 814 fixed with the third bevel gear 821 to rotate, so as to ensure the normal rotation operation of the roller 5.

[0034] The winding mechanism 10 is mounted on the inclinometer body 1. The winding mechanism 10 includes a winding assembly 101 and a transmission assembly 102. The winding assembly 101 includes a mounting plate 1011, a winding wheel 1012, a third motor 1013, a reciprocating screw 1014, a crossbar 1015, a mounting block 1016, and a pulley 1017. The mounting plate 1011 is fixed to the inclinometer body 1. The winding wheel 1012 is rotatably mounted on the mounting plate 1011, and the detection tube 3 is wound around the winding wheel 1012. The third motor 1013 is fixed to the mounting plate 1011 and drives the winding wheel 1012 to rotate. The reciprocating screw 1014 is rotatably mounted on the mounting plate 1011. The crossbar 1015 is fixedly mounted on the mounting plate 1011, passes through the mounting block 1016, and is slidably engaged. The mounting block 1016 is threadedly connected to the reciprocating screw 1014. The pulley 1017 is rotatably mounted on the crossbar 1015, and the side wall of the detection tube 3 passes through the groove of the pulley 1017 and engages with it. The transmission assembly 102 includes a drive shaft 1021, a sprocket 1022, and a chain 1023. The drive shaft 1021 is fixed to the winding wheel 1012 and is coaxially arranged with the winding wheel 1012. There are two sprockets 1022, one of which is fixedly mounted on the drive shaft 1021, and the other is fixedly mounted on the reciprocating screw 1014. The chain 1023 is used to connect the two sprockets 1022, and the chain 1023 meshes with both sprockets 1022. When the third motor 1013 is working, it drives the winding wheel 1012 to rotate, which can perform winding or unwinding operations on the cable 2, so as to facilitate the overall carrying of the device. Furthermore, during the rotation of the take-up reel 1012, the drive shaft 1021 fixed to the take-up reel 1012, one of the sprockets 1022 fixed to the drive shaft 1021, the chain 1023 meshing with the sprocket 1022, the other sprocket 1022 meshing with the chain 1023, and the reciprocating screw 1014 fixed to the other sprocket 1022 all rotate. Under the limit of the crossbar 1015, the mounting block 1016 drives the pulley 1017 to reciprocate along the axis of the reciprocating screw 1014, so that the cable 2 can be evenly wound on the take-up reel 1012.

[0035] Multiple detection tubes 3 are provided, each with a different outer diameter. A mounting post 11 is fixed on the inclinometer body 1. An annular block 12 is fitted onto the mounting post 11, and a sliding through hole 17 is provided through the top of the annular block 12. An electric gripper 13 for fixing the detection tube 3 is fixed on the annular block 12. The number of electric grippers 13 is equal to the number of detection tubes 3, and their positions correspond one-to-one. The size of the electric grippers 13 is adapted to the size of the corresponding detection tube 3. A rotating mechanism 14 is provided on the mounting post 11, and the rotating mechanism 14 is used to drive the annular block 12 to rotate. Since there are multiple detection tubes 3, and each detection tube 3 has a different outer diameter, the detection tube 3 is first disconnected from the cable 2. Then, the rotating mechanism 14 is operated to drive the annular block 12 to rotate, so that the other detection tubes 3 are rotated to the position of the cable 2 and fixed. The detection work can then be carried out through the other detection tubes 3. When the diameter of the detection hole is much larger than that of one of the detection tubes 3, the rotating mechanism 14 can be operated to select other suitable detection tubes 3 to complete the detection operation, thus expanding the applicability of the device.

[0036] The rotating mechanism 14 includes a rotating assembly 141 and a resetting assembly 142. The rotating assembly 141 includes an electric push rod 1411, an annular rotating plate 1412, limiting posts 1413, and ball bearings 1414. The electric push rod 1411 is fixed to the mounting post 11, and the annular rotating plate 1412 is rotatably mounted on the annular block 12 and coaxially arranged with the annular block 12. Multiple limiting posts 1413 are provided, and the limiting posts 1413 are slidably arranged on the annular block 12. The side wall of the mounting post 11 has inclined grooves 15 that slide with the limiting posts 1413, and the ball bearings 1414 are movably mounted on the limiting posts 1413. The side wall of the mounting post 11 has vertical grooves 16. The number of limiting posts 1413, the number of inclined grooves 15, and the number of vertical grooves 16 are all equal and their positions correspond one-to-one. Multiple inclined grooves 15 and multiple vertical grooves 16 are alternately arranged. The upper end of the vertical groove 16 is connected to the upper end of one inclined groove 15, and the lower end of the vertical groove 16 is connected to the lower end of the other inclined groove 15. The side wall of the vertical groove 16 near the axis of the mounting post 11 consists of an upper plane, an inclined surface, and a lower plane. The ball bearing 1414 is in rolling connection with the lower plane of the vertical groove 16. The distance between the upper plane of the vertical groove 16 and the axis of the mounting post 11 is greater than the distance between the side wall of the inclined groove 15 near the axis of the mounting post 11 and the axis of the mounting post 11. The distance between the lower plane of the vertical groove 16 and the axis of the mounting post 11 is less than the distance between the side wall of the inclined groove 15 near the axis of the mounting post 11 and the axis of the mounting post 11. The distance between the inclined surface of the vertical groove 16 and the axis of the mounting post 11 gradually decreases from top to bottom. After the electric push rod 1411 operates, its push rod end retracts until the overall length of the electric push rod 1411 is at its minimum length. This causes the annular rotating plate 1412 connected to the push rod end of the electric push rod 1411, the annular block 12 rotatably connected to the annular rotating plate 1412, the limiting post 1413 connected to the annular block 12, and the ball 1414 connected to the limiting post 1413 to all rise. During this process, the ball 1414 moves from the vertical groove 16 to the inclined groove 15. Similarly, after the electric push rod 1411 operates, its push rod end extends and returns to its original position. This causes the annular rotating plate 1412 connected to the push rod end of the electric push rod 1411, the annular block 12 rotatably connected to the annular rotating plate 1412, and the ball 1414 connected to the limiting post 1413 to all rise. The limiting post 1413 connected to the annular block 12 and the ball 1414 connected to the limiting post 1413 both descend and reset. During this process, since the distance between the upper plane of the vertical groove 16 and the axis of the mounting post 11 is greater than the distance between the side wall of the inclined groove 15 near the axis of the mounting post 11 and the axis of the mounting post 11, the vertical groove 16 limits the limiting post 1413. The limiting post 1413 drives the ball 1414 to move from the upper end of the inclined groove 15 to the lower end of the inclined groove 15, thereby causing the annular block 12 connected to the limiting post 1413, the electric gripper 13 connected to the annular block 12, and the detection tube 3 connected to the electric gripper 13 to rotate. The detection tube 3 can be rotated to the bottom of the cable 2 according to specific requirements.

[0037] The reset assembly 142 is used to drive the limiting post 1413 to reset. The reset assembly 142 includes a sliding block 1421 and a spring 1422. The sliding block 1421 is slidably disposed in the sliding through hole 17 and fixed to the limiting post 1413. The spring 1422 is fixed between the sliding block 1421 and the inner sidewall of the annular block 12. The number of reset assemblies 142, the number of sliding through holes 17, and the number of limiting posts 1413 are all equal and their positions correspond one-to-one. During the movement of the ball 1414 along the vertical groove 16, the ball 1414 first moves from the lower plane of the vertical groove 16 to the inclined surface of the vertical groove 16, then from the inclined surface of the vertical groove 16 to the upper plane of the vertical groove 16, and finally from the upper plane of the vertical groove 16 into the inclined groove 15. During this movement of the ball 1414 along the inclined surface of the vertical groove 16, the distance between the inclined surface of the vertical groove 16 and the axis of the mounting post 11 gradually decreases from top to bottom. The ball 1414 is forced to move the limiting post 1413 in a direction away from the axis of the mounting post 11. When the sliding block 1421 moves and causes the spring 1422 to contract, as the ball 1414 moves from the upper plane of the vertical groove 16 to the inclined groove 15, the spring 1422 gradually extends because the distance between the upper plane of the vertical groove 16 and the axis of the mounting post 11 is greater than the distance between the side wall of the inclined groove 15 near the axis of the mounting post 11 and the axis of the mounting post 11. The sliding block 1421 drives the limiting post 1413 and the ball 1414 to move towards the direction closer to the axis of the mounting post 11 until the ball 1414 is in contact with the surface of the inclined groove 15, so as to ensure the normal movement of the limiting post 1413.

[0038] A first plug 18 is fixed to the top of the detection tube 3, and a second plug 19, which is electrically connected to the cable 2, is fixed to the cable 2. The first plug 18 and the second plug 19 are plugged into each other. A threaded sleeve 20, which is threadedly connected to the first plug 18, is rotatably mounted on the surface of the second plug 19. By rotating the threaded sleeve 20 until it separates from the first plug 18, and then pulling the second plug 19 upwards to separate it from the first plug 18, the operation of separating the cable 2 and the detection tube 3 is completed. Similarly, by plugging the second plug 19 into the first plug 18 and then threading the threaded sleeve 20 into the first plug 18, the operation of connecting the cable 2 and the detection tube 3 is completed.

[0039] A horizontal plate 21 is fixed on the mounting plate 1011. A limiting through hole 22 is provided through the horizontal plate 21 for the cable 2 to pass through. Two limiting wheels 23 are rotatably installed in the limiting through hole 22. The detection tube 3 passes between the two limiting wheels 23, and the side wall of the detection tube 3 makes rolling contact with the side walls of the two limiting wheels 23 that are close to each other. The setting of the limiting wheels 23 improves the stability of the cable 2 when it is released or retracted.
