Description

Technical Field

[0001] The present invention belongs to the technical field of pipe wall detection of vertical pipelines, and specifically relates to a vertical pipeline measurement and detection device and a use method. Background Art

[0002] With the continuous expansion of cities, the number of outdated pipes in old urban areas is increasing. A nationwide project is underway to renovate drainage networks in old urban areas to separate rainwater and sewage. During the network inspection, the depth, diameter, and chamber dimensions of drainage pipes and sewage wells must be measured. Furthermore, the structure of some pipes and sewage wells must be inspected to prevent problems such as ground subsidence. Due to the complex internal environment of the pipes, the confined space between sewage wells and pipe openings, and the potential presence of odorous gases in drainage pipes and some vertical chemical pipelines, workers must wear specialized clothing and masks to monitor the gases within the wells. Once safely in place, they can proceed down the wells for measurement. However, the confined space makes maneuvering difficult, resulting in low measurement efficiency and a significant time-consuming process. To improve efficiency, some workers perform measurements without protective clothing. Furthermore, workers entering and exiting deep well chambers pose a risk of falling. The wellheads remain open for extended periods, emitting odors that disrupt the daily lives of nearby residents.

[0003] After searching, application number 202110212577.9 provides a drainage pipe diameter and pipe depth measuring device, including a vertically arranged main rod with adjustable length, and a movable sleeve is sleeved on the main rod. The movable sleeve can rotate under the action of external force, and can move up and down and position on the main rod; a telescopic measuring rod A and a telescopic measuring rod B are provided at the side end of the main rod, and the telescopic measuring rod A and the telescopic measuring rod B are both a stretching connecting rod mechanism, and the angle between the two telescopic measuring rods can be adjusted by rotating the movable sleeve or the main rod.

[0004] However, staff still need to manually control the device, and can only measure routine data. Some data still requires staff to go down the well to check. Summary of the Invention

[0005] In order to solve the above technical problems, the inventors have arrived at the technical solution of the present invention through practice and summary. The present invention discloses a vertical pipeline measurement and detection device.

[0006] A vertical pipeline measurement and detection device is installed above the pipeline opening and extends into the pipeline for operation. It includes a bracket; the bracket is used instead of manual support to provide higher stability. A mobile motor is installed on the bracket, and the mobile motor is equipped with a cable. One end of the cable is connected to a control terminal with Bluetooth connection function, and the control terminal can be controlled by a mobile phone. The other end of the cable is detachably connected to a detection component.

[0007] The device comprises a bracket; the bracket is equipped with a moving motor, a cable is wound around the moving motor, the moving motor drives the cable to move while controlling the lifting of the cable, the cable is connected to a control terminal, the control terminal can store data and transmit data, and the other end is detachably connected to a detection device;

[0008] The detection component includes a support body, which is connected to a rope at one end of the support body near the pipe mouth, and the rope is connected to a second rotating wheel. A spherical ultrasonic probe is installed at the end of the support body near the pipe mouth, and the spherical ultrasonic probe is equipped with a driving wheel and a mileage wheel. The driving wheel and the mileage wheel are located inside the support body near the pipe mouth. The support body is movably equipped with a shell at the end away from the pipe mouth, and an ultrasonic flaw detector is installed inside the shell. The shell is equipped with an airbag sealing component at the end near the pipe mouth, and an observation component is equipped at the end of the shell away from the shell.

[0009] Furthermore, the support body is included in the shell, and the support body is completely embedded in the outer surface of the shell. The outer surface of the support body is coplanar with the outer surface of the shell. The support body is provided with a groove, and the groove is located on the contact surface of the support body and the shell on both sides along the circumferential direction of the shell. The groove is matched with a telescopic tenon, and the telescopic tenon corresponds to the groove one by one; when the telescopic tenon is in the retracted state, the second rotor rotates and wraps the plastic-coated steel wire rope to pull the support bar toward the shell, so that the support body is completely embedded in the shell, and the telescopic tenon receives the signal transmitted by the second rotor and extends into the groove of the support body to complete the locking, so that the device becomes a whole and will not collide with each other and damage the device during movement.

[0010] Furthermore, the second rotating wheel is located in the middle of the shell, and the supporting bodies include four, which are symmetrically and evenly distributed along the central axis of the shell. The spherical ultrasonic probe is half-wrapped and installed on the supporting body. When the supporting body is unfolded, the supporting body moves toward the pipe wall under the action of gravity. At the same time, the first rotating wheel rotates and the spherical ultrasonic probe on the supporting body contacts the pipe wall. The supporting body leans against the pipe wall under the action of gravity. At the same time, the first rotating wheel is locked, and the spherical ultrasonic probe is electrically connected to the steering drive motor and the mileage wheel. The drive motor drives the spherical ultrasonic probe to rotate, driving the shell to rotate to realize automatic measurement. At the same time, the ultrasonic flaw detector is started and begins to detect. The spherical ultrasonic probe is equipped with a scraper. During the rotation process, stains on the pipe wall adhere to the spherical ultrasonic probe, affecting the rotation of the probe. The scraper can scrape off the stains during the rotation of the probe to avoid affecting the rotation of the probe.

[0011] Furthermore, the scraper is located at the place where the spherical ultrasonic probe extends out of the support body, the inner surface of the scraper is provided with an arc-shaped protrusion, the outer surface of the scraper is an arc surface, the scraper includes a first scraper and a second scraper, the first scraper is matched with the upper surface of the support body near the pipe mouth, the first scraper extends toward the pipe wall, the second scraper is located on the outer surface of the support body near the pipe wall, the second scraper thread is matched with the protruding part of the first scraper, the scraper is arranged in a split type, which is convenient for installation and replacement. The arc surface provided on the outer surface of the scraper causes the stains to accumulate along the arc surface direction and eventually fall off. The arc-shaped protrusion on the inner surface of the scraper prevents the stains from squeezing into the interior of the support body and damaging the device.

[0012] Furthermore, the cable includes a first cable and a second cable, the second cable is arranged inside the first cable, the second cable moves inside the first cable, the length of the second cable is greater than the length of the first cable, one end of the first cable is fixed to the moving motor, and the other end is connected to the airbag blocking component, the second cable passes through the airbag blocking component and is connected to the detection component, the lifting wheel includes a first lifting wheel and a second lifting wheel, the first lifting wheel retracts and extends the first cable, and the second wheel controls the retraction and extension of the second cable. The two cables are controlled separately to better control the lifting and lowering of the components. When the components are separated, the first lifting wheel fixes the first cable, thereby fixing the airbag blocking component;

[0013] Furthermore, it also includes an airbag blocking component, wherein the airbag blocking component is connected to a first cable at one end near the pipe opening, a second cable is arranged inside the cable, and the second cable passes through the airbag blocking component, the airbag blocking component includes an inflatable airbag, the inflatable airbag is equipped with an inflator, an air inlet is provided between the inflator and the housing, and a grille is installed on the air inlet opening of the housing, and the grille is equipped with a grid;

[0014] Furthermore, the inflatable airbag has a double-layer structure, and the airbag is an annular airbag. The outer surface of the inflatable airbag close to the pipe wall is provided with a through hole, and the through hole includes multiple through holes, and the multiple through holes are evenly distributed along the central axis of the shell. The through hole is matched with a plastic-coated steel wire rope, and the plastic-coated steel wire rope is matched with a first rotor. One end of the plastic-coated steel wire rope is fixedly connected to the first rotor, and the other end is fixed inside the shell. The first rotor is electrically connected to the airbag drive motor. The outer layer of the double-layer airbag is wear-resistant, and the service life is extended. A sensor is provided between the inner and outer layers of the airbag. At the same time, the plastic-coated steel wire rope is wrapped around the outer surface of the airbag. In the inflated state, the airbag begins to expand, and at the same time, the first rotor rotates to release the plastic-coated steel wire rope. The plastic-coated steel wire rope is wrapped around the outer surface of the airbag along the through hole, and the plastic-coated steel wire rope is driven to move when the airbag expands. When the airbag is completely in contact with the inner wall of the pipe, the inflator receives the sensor signal to stop inflating, and at the same time the first rotor is locked to seal the pipe, thereby avoiding the long-term opening of the pipe causing odor to be emitted.

[0015] Furthermore, the device also includes a separation component, which includes a fixed disc, which is bolted to the airbag blocking component. The fixed disc is located below the airbag blocking component. The fixed disc is provided with a fixing hole along the circumferential direction, and the fixing hole is cooperated with a telescopic fixing rod. A through hole is provided in the center of the fixed disc, and the through hole is cooperated with a fixing boss. The fixing boss is connected to a shell, and the fixing boss is located on the upper surface of the shell. The fixed boss and the shell are integrated. The fixed boss is provided with fixing holes around the circumferential direction, and the fixing hole is cooperated with a telescopic fixing rod. The telescopic fixing rod includes a telescopic motor, which receives a control signal from a control terminal to control the extension and retraction of the fixing rod. A second cable is connected to the upper surface of the fixed boss; a second bearing is provided at the connection between the fixed boss and the detection component. When the detection component rotates, the second cable does not rotate with the component, thereby avoiding twisting of the cable. When the airbag blocking component is separated from the detection component, the first cable reaches its maximum length and cannot continue to descend, thereby supporting the airbag blocking component. At the same time, the second cable continues to move inside the first cable, and the mobile monitoring component reaches the detection position. The maximum descending length of the first cable can be controlled by the staff to adapt to the sealing function of pipes of different depths.

[0016] Furthermore, the observation component includes a semicircular transparent cover, which is located at the bottom of the shell and is bolted to the shell. A camera is installed inside the semicircular transparent cover. Through the camera, the staff can observe whether there are obvious cracks or deformations on the pipe wall when it is blocked, thereby improving work efficiency.

[0017] Furthermore, the cable is threadedly connected to the top of the shell, and a first bearing is provided at the connection between the shell and the airbag sealing component, so that the rotation of the shell will not drive the airbag sealing component to rotate, thereby improving the sealing of the sealing. A gas detector is provided at the bottom of the shell, which can directly detect whether there is harmful gas in the pipeline. The shell is waterproof and dustproof, and the device is connected to an external energy source; the device is waterproof and dustproof to avoid the influence of sewage and dust in the pipeline, and the external power supply greatly improves the service life of the device.

[0018] Furthermore, the bracket can be folded and is provided with a toolbox; the folded bracket is convenient for movement, and the toolbox stores tools to cope with different usage scenarios and on-site maintenance.

[0019] The present invention also discloses: a method for using a vertical pipeline measurement and detection device, comprising the following steps:

[0020] S1. Set up the bracket: Set up the bracket above the center of the pipeline, connect the power supply, start the mobile motor, and perform a self-test. Check the cables for damage and ensure smooth sliding between the first and second cables. Once all is confirmed, wind the cables around the motor's wheels.

[0021] S2. Self-test; connect the cable to the device, connect the first cable to the upper end of the airbag blocking component, tighten the connection fastening nut, then pass the second cable through the airbag blocking component and connect it to the fixed boss, connect the other end of the cable to the control terminal, start the control terminal, start the mobile motor to lift the device, check whether there is obvious damage on the outer surface of the device, whether there is sludge and other pollutants remaining on the scraper, start the airbag blocking component on the control terminal, the inflator receives the signal from the control terminal to start working, and at the same time outputs a signal to open the air valve, the inflator takes in air through the air inlet duct, the air enters the air inlet duct through the grille on the outer shell, is compressed by the inflator and reaches the inflation channel of the inflator outlet, and enters the inner air through the inflation channel. The bag inflates the airbag, the inflator starts and sends a signal to the first rotor, the first rotor unlocks and starts to rotate from the initial position to release the plastic-coated steel wire rope, to ensure that the plastic-coated steel wire rope passing through the through hole of the outer airbag when the airbag is inflated can move with the airbag, to avoid the plastic-coated steel wire rope affecting the inflation of the airbag, to observe whether the airbag is leaking, whether the inner and outer layers are damaged, and whether the internal sensor of the airbag is working normally. After the inspection of the airbag is completed, the control terminal sends an order to stop inflation, the inflator stops intake, and the upper air valve of the inflation pipe continues to open. The first rotor starts to rotate in the opposite direction to wind and shrink the plastic-coated steel wire rope. The plastic-coated steel wire rope shrinks and pulls the airbag toward the center of the shell until it shrinks. When the first wheel returns to its initial position, check whether the inflatable airbag shrinks to the specified position normally. After the inspection is completed, start the detection component through the control terminal. The telescopic tenon receives the control terminal signal through the cable, releases the lock on the support body, and sends a signal to the second wheel at the same time. The second wheel starts to rotate from the initial position to release the plastic-coated steel wire rope. The support body stretches away from the shell under the action of gravity. When the support body reaches the maximum extension, the plastic-coated steel wire rope wrapped on the second wheel is completely released and straightened under the traction of the support body. Check whether the extension is smooth and whether the plastic-coated steel wire rope is damaged. At the same time, the control terminal starts the measurement and detection program, and the drive motor receives the signal from the control terminal. The drive motor drives The driving wheel rotates, and the driving wheel is close to the spherical ultrasonic probe, which is driven by friction to rotate the spherical ultrasonic probe. The rotation of the spherical ultrasonic probe drives the odometer to rotate through friction, and the rotation of the odometer drives the odometer to work. Observe whether each component rotates normally, calibrate the odometer data, and calibrate the ultrasonic detector after completion. After calibration, a stop command is issued through the control terminal, the drive motor stops running, the driving wheel stops rotating, and the spherical ultrasonic probe also stops rotating. At the same time, the second rotating wheel receives the stop signal from the control terminal through the cable, and the second rotating wheel starts to rotate in the opposite direction to wind the shrink-wrapped plastic wire rope, which pulls the support part toward the center of the shell.When the support body is fully embedded in the shell, the second rotating wheel returns to the initial position and is locked, and at the same time sends a signal to the telescopic tenon. The telescopic tenon receives the signal and extends to the side groove of the support part to lock the support body. Finally, the lifting device starts the separation component through the control terminal. The telescopic fixing rod inside the fixed disc receives the signal through the cable and retracts from the fixing hole of the fixed boss, releasing the fastening of the fixed boss. At the same time, the moving motor releases the second cable and fixes the first cable. The detection component moves downward under the control of the drive motor to check whether the airbag blocking component and the detection component can be separated normally. After the inspection is completed, the control terminal controls the drive motor to lift the second cable to drive the detection component back to its original height. When the fixed boss enters the through hole below the center of the fixed disc, the telescopic fixing rod inside the fixed disc extends into the fixing hole on the fixed boss to complete the combination and open the pipe opening. The control terminal drives the drive motor to move the device into the pipe.

[0022] S3. Deploy the airbag blocking component; start the airbag blocking component on the control terminal, the inflator receives the signal from the control terminal to start working, and at the same time outputs a signal to open the air valve. The inflator takes in air through the air inlet duct, and the air enters the air inlet duct through the grille on the outer shell. After being compressed by the inflator, the air reaches the inflation channel of the inflator air outlet, and enters the inner airbag through the inflation channel. The inflatable airbag is inflated and expanded. The inflator is turned on and a signal is sent to the first rotor. The first rotor is unlocked and starts to rotate to release the plastic-coated steel wire rope. The inflatable airbag is inflated and expanded, driving the plastic-coated steel wire rope passing through the through hole of the outer airbag to move until the internal sensor of the inflatable airbag detects that the inflatable airbag has completely blocked the pipeline, and sends a signal to the inflator and the first rotor. The inflator stops working and controls the air valve to close, blocking the inflation channel, and the first rotor is locked;

[0023] S4. The detection component starts working: the detection component is started through the control terminal, and the telescopic tenon receives the control terminal signal through the cable, unlocks the support body, and sends a signal to the second rotor. The second rotor starts to rotate from the initial state to release the plastic-coated steel wire rope. The support body extends away from the shell under the action of gravity until the spherical ultrasonic probe contacts the pipe wall. After the spherical ultrasonic probe contacts the pipe wall, the sensor on the support body sends a signal to the first rotor, and the first rotor is locked. The control terminal starts the measurement and detection program, and the drive motor receives the signal from the control terminal. The drive motor drives the drive wheel to rotate. The drive wheel is close to the spherical ultrasonic probe and drives the spherical ultrasonic probe to rotate through friction. The rotation of the spherical ultrasonic probe drives the mileage wheel to rotate through friction. The rotation of the mileage wheel drives the mileage meter to work. At the same time, the ultrasonic flaw detector starts working, and transmits data to the control terminal after one rotation. The data on the control terminal is used to select whether to detect again.

[0024] S5. Separation Component: When deeper inspection is required in the pipeline, the separation component is activated via the control terminal. The telescopic fixing rod receives a signal from the control terminal via a cable, retracting the rod inside the fixed disc from the fixing hole of the fixing boss, releasing the fixing boss. The inspection component continues to move downward under the pull of the drive motor, while the airbag blocking device remains in the blocking position.

[0025] S6. Connect the detection component; when the data collection is completed, a stop command is issued through the control terminal, the drive motor stops running, the drive wheel stops rotating, and the spherical ultrasonic probe also stops rotating. At the same time, the second wheel receives a stop signal from the control terminal through the cable, and the second wheel starts to rotate in the opposite direction to wind the shrink-wrapped plastic wire rope, and the shrink-wrapped plastic wire rope is used to pull the support part toward the center position of the shell. When the support body returns to the initial position, the second wheel returns to the initial position and is locked, and then sends a signal to the telescopic tenon. The telescopic tenon receives the signal and extends to the side groove of the support part to lock the support body. At the same time as the support body shrinks, the drive motor drives the spherical ultrasonic probe to rotate, and the friction between the scraper and the surface of the spherical ultrasonic probe removes sludge and other impurities on the surface of the spherical ultrasonic probe. The control terminal controls the drive motor to lift the detection component to the corresponding height. When the fixed boss enters the through hole below the center of the fixed disk, the telescopic fixing rod inside the fixed disk extends into the fixing hole on the fixed boss to complete the fixation;

[0026] S7. Contract the airbag sealing component. The control terminal issues a contraction command, opening the air valve on the inflation pipe. The gas in the airbag is released through the inflation pipe and discharged through the inflator's air inlet. The first rotor begins to rotate in the opposite direction, wrapping the shrinking plastic-coated wire rope. The shrinking plastic-coated wire rope pulls the airbag toward the center of the shell until the first rotor returns to its initial position. Check whether the airbag has contracted normally to the designated position.

[0027] S8. Recover the device. After the device has been retracted within the pipe, control the drive motor on the bracket to lift the device above the pipe opening. Close the pipe opening and inspect the device for damage. After completion, disconnect the power supply, clean the device, loosen the fastening nuts connecting the cable to the device, and recover the device for maintenance.

[0028] S9. Recover the bracket; remove the drive motor and supporting facilities on the bracket, place them separately, unlock the bracket foot moving wheels, and retract and move the bracket.

[0029] Compared with the prior art, the present invention can achieve the following technical effects:

[0030] The establishment of the bracket reduces the workload of the staff. The bracket and the mobile motor automatically retract and extend the detection device. After connecting the power supply and cable, the mobile motor moves the device to the specified position. The control terminal controls the telescopic tenon to retract, releasing the lock on the support body. At the same time, the second rotary wheel starts to rotate to loosen the plastic-coated steel wire rope. The support body moves toward the pipe wall under the action of gravity, and pulls the plastic-coated steel wire rope to move until the spherical ultrasonic probe at the upper end of the support body touches the pipe wall. The second rotary wheel is locked to limit the movement of the support body, and the driving machine and the ultrasonic flaw detector start working. The driving machine drives the spherical ultrasonic probe to rotate, so that the probe moves along the pipe wall, and at the same time drives the mileage wheel to move and record the moving distance. The data is transmitted to the control terminal through the cable. The staff do not need to go down the well to work, which greatly improves work efficiency. When the staff sees suspicious data on the control terminal, they can rotate the control device on the control terminal to the target position for re-detection, avoiding the need for staff to go down the well for calibration, thereby improving work efficiency.

[0031] The airbag sealing component is activated through the control terminal, the inflator starts working, the grille and grid intercept debris in the pipeline from entering the inflator, the second rotor is unlocked and starts to rotate, and the airbag begins to expand under the action of the inflator, driving the plastic-coated steel wire rope wrapped around the outer surface of the airbag to move until it completely contacts the pipe wall. The sensor sends a signal, the inflator stops working, and the second rotor is locked. The airbag sealing is completed, avoiding the long-term opening of the pipeline operation and the release of odor; at this time, the staff can also observe the pipe wall through the camera at the bottom of the device to determine whether it is necessary to go down the well for maintenance, thereby improving work efficiency. At the same time, the gas detector helps detect whether there is harmful gas in the pipeline, enabling the staff to know the structure and situation inside the pipeline, take early protection, and avoid dangerous situations.

When the support body 2 is completely embedded in the shell 201, the second rotating wheel 402 returns to the initial position and is locked. At the same time, a signal is sent to the telescopic tenon. The telescopic tenon receives the signal and extends to the side groove 202 of the support part 2 to lock the support body 2.

After the inspection is completed, the control terminal controls the second lifting wheel on the drive motor 101 to lift the second cable 1022 and drive the detection component back to its original height. When the fixed boss 407 enters the through hole below the center of the fixed disk 405, the retractable fixing rod 406 inside the fixed disk 405 extends into the fixing hole 408 on the fixed boss 407 to fix the detection component. The pipe opening is opened, and the control terminal drives the lifting wheel 103 on the drive motor 101 to move the device into the pipe.

The inflator 14 stops working and controls the air valve 12 to close, blocking the inflation channel 13, and the first rotor 401 is locked.

[0066] S4. The detection component starts working: The detection component is activated by the control terminal. The telescopic tenon receives the control terminal signal through the cable, unlocks the support body 2, and sends a signal to the second rotary wheel 402. The second rotary wheel 402 starts to rotate from the initial state to release the plastic-coated steel wire rope 3. The support body 2 extends away from the housing 201 under the action of gravity until the spherical ultrasonic probe 5 contacts the pipe wall. After the spherical ultrasonic probe 5 contacts the pipe wall, the sensor on the support body 2 sends a signal to the first rotary wheel 402, and the first rotary wheel 401 is locked. The control terminal starts the measurement and detection program. The drive motor 403 receives the signal from the control terminal and drives the drive wheel 4031 to rotate.

At the same time, the ultrasonic flaw detector starts working and transmits data to the control terminal after one rotation. The data on the control terminal is used to select whether to test again.

[0067] S5. Separation Component: When deeper inspection is required in the pipeline, the separation component is activated via the control terminal. Telescopic fixing rod 406 receives a signal from the control terminal via a cable, retracting telescopic fixing rod 406 within fixing disk 405 from fixing hole 408 of fixing boss 407, releasing fixing boss 407.

[0068] S6. Connect the detection components; when the data collection is completed, the control terminal issues a stop command, the drive motor 403 stops running, the drive wheel 4031 stops rotating, the spherical ultrasonic probe 5 also stops rotating, and at the same time the second rotating wheel 402 receives a stop signal from the control terminal via a cable, and the second rotating wheel 402 starts to rotate in the opposite direction to wind the shrink-wrapped plastic-coated wire rope 3, and the shrink-wrapped plastic-coated wire rope 3 pulls the support part 2 to retract toward the center position of the shell 201. When the support body 2 returns to its initial position, the second rotating wheel 402 returns to its initial position and is locked, and then sends a signal to the telescopic tenon, and the telescopic tenon receives the signal. The number extends outward from the locking support body 2 to the side groove 202 of the support part 2. When the support body contracts, the driving motor 403 drives the spherical ultrasonic probe 5 to rotate, and the friction between the scraper 6 and the surface of the spherical ultrasonic probe 5 is used to remove sludge and other impurities on the surface of the spherical ultrasonic probe 5. The second lifting wheel on the driving motor 101 is controlled by the control terminal to lift the second cable 1022 to drive the detection component to the corresponding height. When the fixed boss 407 enters the through hole below the center of the fixed disk 405, the telescopic fixing rod 406 inside the fixed disk 405 extends into the fixing hole 408 on the fixed boss 407 to complete the fixation;

[0069] S7. Contraction of the airbag blocking component; the control terminal issues a contraction command, the air valve 12 on the inflation pipe 13 opens the airbag 7 and begins to deflate. At the same time, the first runner 401 begins to rotate in the opposite direction to wind and shrink the plastic-coated wire rope 3. The plastic-coated wire rope 3 contracts and pulls the airbag 7 toward the center of the housing 201 until the first runner 401 returns to its initial position. Check whether the airbag 7 has contracted normally to the specified position.

[0071] S9. Recover the bracket 1; remove the drive motor and supporting facilities on the bracket 1, place them separately, unlock the movable wheels of the bracket 1 footrest, and retract and move the bracket 1.

[0072] Example 2

[0073] When the device is working, the telescopic tenon 203 retracts, releasing the lock on the support body 2, and the support body 2 unfolds. The support body 2 moves toward the pipe wall under the action of gravity, and at the same time pulls the plastic-coated steel wire rope 3 to drive the second rotating wheel 402 to rotate. Finally, the support body 2 rests on the surface of the pipe wall. After the spherical ultrasonic probe 5 on the support body 2 touches the pipe wall, the probe sends a signal, the second rotating wheel 402 is locked, and the spherical ultrasonic probe 5 is electrically connected to the steering drive motor and the mileage wheel. After the second rotating wheel 402 is locked, the drive motor drives the spherical ultrasonic probe 5 to rotate along the pipe wall, driving the shell and the mileage wheel to rotate. After the mileage wheel rotates, the moving distance is calculated by the number of rotations, and the pipeline size is obtained and transmitted to the control terminal to realize automatic measurement. At the same time, the ultrasonic flaw detector is started and turned on. When the pipe wall is detected, a scraper 6 is provided on the side of the spherical ultrasonic probe 5. The scraper 6 is located at the place where the spherical ultrasonic probe 5 extends out of the support body 2. When the spherical ultrasonic probe 5 rotates along the pipe wall, sludge and other impurities adhere to the probe. When the probe rotates to the scraper 6, the scraper 6 scrapes off the sludge to prevent the probe from bringing the sludge into the support body 2. The inner surface of the scraper 6 is provided with an arc-shaped protrusion, and the outer surface of the scraper 6 is an arc surface. The scraper 6 includes a first scraper 601 and a second scraper 602. The first scraper 601 is matched with the upper surface of the support body 2 near the pipe mouth. The first scraper 601 extends toward the pipe wall. The second scraper 602 is located on the outer surface of the support body 2 near the pipe wall. The second scraper 602 is threadedly matched with the protruding part of the first scraper 601.

[0074] Before the detection component works, the blocking component starts working, the inflator starts to inflate air into the airbag, and the grille and grid at the bottom of the shell cooperate to prevent impurities in the pipe from entering the inflator and causing blockage. The airbag starts to inflate. Since the upper and lower surfaces are restricted by the shell, the airbag expands toward the pipe wall, and at the same time drives the plastic-coated steel wire rope 3 wrapped around the outer surface of the airbag to move. When the inflator starts working, the output signal causes the first rotor 401 to unlock and start rotating, releasing the plastic-coated steel wire rope 3. When the airbag completely contacts the pipe wall, the sensor inside the airbag outputs a signal, the inflator stops inflating and the first rotor 401 is locked, restricting the movement of the plastic-coated steel wire rope 3, thereby sealing the pipe and preventing odor from escaping.

[0075] Example 3

[0076] When the device is finished working, the staff controls the device to retract through the control terminal, the second wheel 402 starts, and rotates in the opposite direction to wind the plastic-coated steel wire rope 3, pulling the support body 2 to move away from the pipe wall. At the same time, the driving machine drives the spherical ultrasonic probe 5 to rotate, and uses the scraper 6 to remove sludge and other impurities attached to the probe. When the second wheel 402 rotates in the opposite direction to the initial position and is locked, the support body 2 is completely embedded in the shell. The second wheel 402 sends a signal to the telescopic tenon, and the telescopic tenon extends into the groove of the support body 2 to complete the locking.

[0077] When the detection component has completed its contraction, the inflatable airbag 7 begins to deflate. While deflation is occurring, the first rotary wheel 401 begins to rotate in the opposite direction, contracting the plastic-coated steel wire rope 3. As the gas inside the inflatable airbag 7 is discharged, the airbag contracts. At the same time, the plastic-coated steel wire rope 3 passing through the through hole 8 on the outer surface of the airbag further contracts under the traction of the first rotary wheel 401. When the first rotary wheel 401 contracts to the initial position and is locked, the airbag is now wound around the plastic-coated steel wire rope 3 and contracts to the initial position. After contraction is completed, the drive motor lifts the device, and the staff loosens the cable nut to fold the device.

At the same time, after the second rotating wheel 402 rotates the spherical ultrasonic probe 5 on the support body 2 and contacts the pipe wall, the support body 2 leans against the pipe wall under the action of gravity. At the same time, the second rotating wheel 402 is locked, and the spherical ultrasonic probe 5 is electrically connected to the steering drive motor and the mileage wheel. The drive motor drives the spherical ultrasonic probe 5 to rotate, driving the shell to rotate to achieve automatic measurement. At the same time, the ultrasonic flaw detector is started and begins to detect. The spherical ultrasonic probe 5 is equipped with a scraper 6. During the rotation process, stains on the pipe wall adhere to the spherical ultrasonic probe 5, affecting the rotation of the probe. The scraper 6 can scrape off the stains during the rotation of the probe to avoid affecting the rotation of the probe.

[0079] When the staff needs to inspect deeper into the pipeline, they activate the separation component through the control terminal, and the telescopic fixing rod 406 retracts into the fixed pipe disc, releasing the lock on the fixed boss 407. The inspection component continues to descend through the cable 1022. At this time, the cable 1021 reaches the limit length, and the cable 1022 moves inside the cable 1021, so that the inspection component moves deeper into the pipeline, and the airbag blocking device remains in the blocking position.

[0080] When the data collection is completed, the staff starts the device recovery program through the control terminal. After the detection component receives the signal, the first rotating wheel 402 is unlocked, and the plastic-wrapped steel wire rope 202 is rotated in the opposite direction to pull the support body 2, so that the support body 2 is closer to the shell 201. At the same time, the driving wheel 403 drives the spherical ultrasonic probe 5 to rotate, and the friction between the scraper 6 and the surface of the spherical ultrasonic probe 5 is used to remove sludge and other impurities on the surface of the spherical ultrasonic probe 5. The first rotating wheel 402 rotates continuously until the support body 2 is completely embedded in the shell 201. After the telescopic tenon extends out to fix the support body 2, the first rotating wheel 402 stops rotating and locks. When the detection component shrinks to the initial state, the driving motor on the bracket 1 lifts the cable 102 to drive the detection component to rise to the bottom of the airbag blocking component. The fixed boss 407 enters the central through hole of the fixed disc 405, and the telescopic fixing rod 406 extends out, passes through the fixing hole 408 to fix the detection component to complete the connection;

The first scraper 601 extends toward the pipe wall. The second scraper 602 is located on the outer surface of the support body 2 near the pipe wall. The second scraper 602 is threadedly matched with the protruding part of the first scraper 601. The arc surface set on the outer surface of the scraper 6 causes the stains to accumulate along the arc surface direction and eventually fall off. The arc-shaped protrusion on the inner surface of the scraper 6 prevents the stains from squeezing into the interior of the support body 2 and damaging the device.

[0082] The airbag blocking component includes an inflatable airbag 7, which is equipped with an inflator. The inflator is located in the lower part of the shell. A grille is installed at the lower part of the shell. The grille is equipped with a grid. The inflator inflates the airbag, and the grille is the air inlet of the inflator. The grid intercepts debris in the pipeline from entering the inflator and causing blockage.

The through hole 8 includes multiple through holes 8, and the multiple through holes 8 are evenly distributed along the central axis of the shell. The through hole 8 is matched with a plastic-coated steel wire rope 3, and the plastic-coated steel wire rope 3 is matched with a first runner 401. One end of the plastic-coated steel wire rope 3 is fixedly connected to the upper surface of the first runner 401, and the other end is wound around the first runner 401. The first runner 401 is electrically connected to the airbag drive motor. The outer layer of the double-layer airbag is wear-resistant and extends its service life. A sensor is provided between the inner and outer layers of the airbag, and the plastic-coated steel wire rope 3 is wound around the outer surface of the airbag.

The airbag blocking component is started on the control terminal. The inflator (14) receives the signal from the control terminal and starts working, and at the same time outputs a signal to open the air valve (12). The inflator (14) takes in air through the air inlet duct (11), and the air passes through the grid on the outer shell (201). The grille (10) enters the air inlet (11), is compressed by the inflator (15) and reaches the inflation channel (13) of the air outlet of the inflator (15), and enters the inner airbag (702) through the inflation channel (13) to inflate the inflatable airbag (7). The inflator (14) is turned on and sends a signal to the first rotating wheel (401). The first rotating wheel (401) is unlocked and starts to rotate from the initial position to release the plastic-coated steel wire rope (3), so as to ensure that the plastic-coated steel wire rope (3) passing through the through hole (8) on the surface of the outer airbag (701) can move with the inflatable airbag (7) when the inflatable airbag (7) is inflated, so as to avoid the plastic-coated steel wire rope (3) affecting the inflation of the inflatable airbag (7), and observe whether the inflatable airbag (7) is leaking and whether the internal sensor of the inflatable airbag (7) is working normally. The control terminal issues an inflation termination instruction, the inflator (14) stops air intake, and the upper air valve (12) of the inflation pipe (13) continues to open to release the gas inside the inflatable airbag (7). The first rotating wheel (401) starts to rotate in the opposite direction to wind and shrink the plastic-coated steel wire rope (3). The plastic-coated steel wire rope (3) shrinks and pulls the outer airbag (701) toward the center of the shell (201) until the first rotating wheel (401) returns to the initial position. It is checked whether the inflatable airbag (7) shrinks to the specified position normally.
