An instrument for detecting underground pipelines in engineering projects and its usage method

Abstract

This invention discloses a detector and its method for using underground pipelines, belonging to the field of underground engineering technology. The detector and method, through the installation of control valves, drive components, and a cleaning mechanism, activates all four control valves simultaneously when opened from the outside, allowing accumulated gas on the inner wall of the detector housing to be released. When cracks appear on the pipeline surface, the sealed housing is in close contact with the pipeline's inner wall, and the fan continuously discharges gas. If cracks exist on the pipeline surface, the gas will escape along the cracks, and the pressure detector inside the sealed housing will issue an alarm. This allows the detector to not only detect the pipeline's direction but also check for damage or hidden hazards. Furthermore, it significantly reduces the manpower required for the detector, and the close contact with the pipeline avoids errors in the pipeline detection data.

[0002] Pipeline detectors can quickly and accurately detect the location, direction, and depth of underground water pipes, metal pipes, cables, etc., without damaging the ground cover, as well as the location and size of damage points in the anti-corrosion layer of steel pipes.

The connecting pipe is connected to the plurality of first sliding sleeves through the plurality of conduits, and a sliding tube is slidably connected inside each of the plurality of first sliding sleeves.

[0020] As a further aspect of the present invention: four control valves are provided on one side of the sealing assembly, the sealing assembly is connected to four telescopic assemblies, and the other end of the four telescopic assemblies is connected to four sealing shells.

[0021] The other side of the sealing assembly is connected to the connecting pipe.

[0022] As a further aspect of the present invention: the sealing assembly includes a detection housing, and a flow groove is formed inside the detection housing;

[0023] The control valve is located on one side of the detection housing, and the other side of the detection housing is connected to the connecting pipe. All four telescopic components are located outside the detection housing.

[0024] The telescopic component includes a second sliding sleeve, a sliding rod is slidably connected inside the second sliding sleeve, and a plurality of first springs are provided inside the second sliding sleeve;

[0025] The other end of the second sliding sleeve is connected to the detection housing, and the other end of the sliding rod is connected to the sealing housing. A pressure detector is installed inside the sealing housing.

[0026] As a further embodiment of the present invention: a groove is provided on one side of the collecting shell, a slider is slidably connected in the groove, one end of the slider is fixedly connected to an extension plate, the extension plate is in contact with the collecting shell, and a plurality of second springs are fixedly connected in the groove, the two ends of the second springs being fixedly connected to the lower part of the inner wall of the groove and the lower part of the slider, respectively.

[0027] The pushing component is connected to the drive shaft of the motor, and several collection shells are fixedly connected to the outside of the motor drive shaft.

[0028] As a further aspect of the present invention: the pushing component includes a first connecting block, a ball block is fixedly connected to one side of the first connecting block, a spiral blade is fixedly connected to the outside of the first connecting block, the other side of the first connecting block is fixedly connected to a second connecting block, and a ball sleeve is fixedly connected to the other side of the second connecting block, wherein the diameter of the ball block is adapted to the diameter of the inner wall of the ball sleeve.

[0029] One side of the first connecting block is connected to the motor drive shaft.

[0030] A method for using an underground pipeline detector includes the following steps:

[0031] S1. When using this detector, the probe needs to be installed on one side of the detector housing, and then the drive battery of the power unit needs to be replaced. At this time, the pressure detection device installed inside the sealed housing needs to be checked. After the check and replacement are completed, one end of the detector can be connected to the pull rope and inserted into the pipeline for detection.

[0032] S2. During the detection process, the motor starts and drives the fan to run, so that the fan can draw in outside air through the air intake pipe and discharge the air into the first sliding sleeve through the connecting pipe and the conduit. The air pressure in the first sliding sleeve rises rapidly. At the same time, the sliding tube in the first sliding sleeve will move accordingly. Since the first sliding sleeve and the sliding tube are both arc-shaped, the sliding tube will push the fixed plate to rotate along the first pin shaft during the movement, so that the pulley is in contact with the inner wall of the pipe. At the same time, the discharged gas will also push the sliding rod to slide in the second sliding sleeve, so that the sealing shell is in contact with the inner wall of the pipe, and the gas will be discharged into the sealing shell.

[0033] S3. When personnel open the control valve from the outside, the four control valves will start simultaneously, allowing the gas accumulated on the inner wall of the detection housing to be discharged, thereby providing a reaction force for the forward movement of the detector and achieving the effect of pushing the detector to move in the pipeline. When a crack appears on the surface of the pipeline, since the sealing housing is in close contact with the inner wall of the pipeline and the fan continues to discharge gas, if there is a crack on the surface of the pipeline, the gas will be discharged along the crack on the surface of the pipeline, and the pressure detector inside the sealing housing will sound an alarm.

[0034] S4. When the motor is running, the motor will drive the first connecting block and the second connecting block to rotate through the drive shaft on one side. Since the first connecting block and the second connecting block are fixedly connected to the outside of the spiral blades, the spiral blades can rub against the inner wall of the pipe during the rotation.

[0035] S5. When the motor is running, it will simultaneously drive the collection shell to rotate, causing the extension plate on the inner wall of the collection shell to move outward rapidly under the action of centrifugal force. At this time, the slider will slide in the groove. When the extension plate moves to the limit position, it will fit against the inner wall of the pipe, so that the detector can not only clean the inner wall of the pipe, but also collect the impurities that are cleaned.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows: The underground pipeline detector and its usage method, by setting up control valves, drive components and cleaning mechanisms, when personnel open the control valves from the outside, all four control valves will be activated simultaneously, allowing the gas accumulated on the inner wall of the detector housing to be discharged, thereby providing a reaction force for the detector to move forward, achieving the effect of moving the detector within the pipeline. When cracks appear on the pipeline surface, because the sealed housing is in close contact with the inner wall of the pipeline and the fan continuously discharges gas, if there are cracks on the pipeline surface, the gas will be discharged along the cracks on the pipeline surface, and the pressure detector inside the sealed housing will sound an alarm. This allows the detector to not only detect the direction of the pipeline, but also to check for damage or hidden hazards in the pipeline. At the same time, it greatly reduces the manpower required for the detector, and the close contact with the pipeline movement can avoid errors in the pipeline detection data.

[0050] Example 1

[0051] like Figure 1-3 and Figure 6 As shown, the present invention provides a technical solution: a detector for underground pipelines in engineering projects and a method for using it, comprising,

[0052] The drive mechanism 100 includes a power assembly 101, a plurality of support plates 102 disposed outside the power assembly 101, a mounting sleeve 103, and a bracket assembly 104. The power assembly 101 is connected to the mounting sleeve 103 via the support plates 102, and the bracket assembly 104 is disposed outside the mounting sleeve 103.

[0053] The detection mechanism 200 includes a sealing assembly 201, a control valve 202, a plurality of telescopic components 203 disposed outside the sealing assembly 201, and a sealing housing 204, wherein the sealing assembly 201 is connected to the plurality of sealing housings 204 through the plurality of telescopic components 203, and the sealing assembly 201 communicates with the telescopic components 203; and,

[0054] The cleaning mechanism 300 includes a collection shell 301, an extension plate 304, and a pushing assembly 306. There are several collection shells 301, and one side of each collection shell 301 overlaps with one extension plate 304.

[0055] Furthermore: the power assembly 101 is fixedly connected to several support plates 102, and the other side of the support plates 102 is fixedly connected to the inner wall of the same mounting sleeve 103. The power assembly 101 is fixedly connected to the same mounting sleeve 103 through the support plates 102. The mounting sleeve 103 is fixedly connected to several bracket assemblies 104. One side of the bracket assembly 104 is fixedly connected to the exhaust assembly 105. Several air intake assemblies 106 are provided outside the power assembly 101. The power assembly 101 includes a motor 101a. One end of the motor 101a is connected to the fan 101b. The air intake port of the fan 101b is connected to the air intake assembly 106, and the exhaust port of the fan 101b is connected to the exhaust assembly. 105 is connected to the air intake assembly 106, which includes an air intake pipe 106a. One end of the air intake pipe 106a is connected to the air intake cover 106b, and the other end of the air intake pipe 106a is connected to the air intake of the fan 101b. The bracket assembly 104 includes a first pin 104a, a fixing plate 104b is fixedly connected to the outside of the first pin 104a, the first pin 104a is hinged to a second pin 104c through the fixing plate 104b, the second pin 104c is fixedly connected to the other side of the fixing plate 104b, a pulley 104d is fixedly connected to the outside of the second pin 104c, the first pin 104a is hinged to the mounting sleeve 103 through the base plates on both sides, and the fixing plate 104b is fixedly connected to one end of the exhaust assembly 105.

[0056] Because of the support plate 102, which is a heat sink, the air velocity on the surface of the air intake shroud 106b increases when the air intake pipe 106a and the air intake shroud 106b draw in external gas. Furthermore, the air intake shroud 106b is close to the support plate 102, thus increasing the air velocity on the surface of the support plate 102. This improves the heat dissipation effect of the support plate 102 on the motor 101a, ensuring that the detector is less prone to overheating during prolonged use and thus protecting its service life.

[0057] The exhaust assembly 105 includes a connecting pipe 105a, with several conduits 105b fixedly connected to the outside of the connecting pipe 105a. Each of the conduits 105b has a first sliding sleeve 105c at its other end. The connecting pipe 105a is connected to the several first sliding sleeves 105c through the conduits 105b. Each of the first sliding sleeves 105c has a sliding tube 105d slidably connected inside. The other end of the sliding tube 105d is fixedly connected to a fixing plate 104b. The two ends of the connecting pipe 105a are respectively connected to the exhaust port of the detection mechanism 200 and the fan. Four control valves 202 are provided on one side of the sealing assembly 201. The sealing assembly 201 is connected to four telescopic assemblies 203, and the other end of the four telescopic assemblies 203 is connected to four sealing shells 204. The other side of the sealing assembly 201 is connected to the connecting pipe 105a.

[0058] In this embodiment, by setting up control valve 202, drive assembly, and cleaning mechanism 300, when personnel open control valve 202 from the outside, all four control valves 202 will be activated simultaneously, allowing the gas accumulated on the inner wall of the detection housing 201a to be discharged, thereby providing a reaction force for the forward movement of the detector and achieving the effect of pushing the detector to move within the pipeline. When cracks appear on the pipeline surface, since the sealing housing 204 is in close contact with the inner wall of the pipeline and the fan 101b continuously discharges gas, if there are cracks on the pipeline surface, the gas will be discharged along the cracks on the pipeline surface, and the pressure detector inside the sealing housing 204 will sound an alarm. This allows the detector to not only detect the direction of the pipeline, but also to check for damage or hidden hazards in the pipeline. At the same time, it greatly reduces the manpower required for the detector, and the movement close to the pipeline can avoid errors in the pipeline detection data.

[0059] Example 2

[0060] Combined with appendix Figure 2 and attached Figure 4 It is concluded that: the sealing assembly 201 includes a detection housing 201a, a flow groove 201b is provided inside the detection housing 201a, a control valve 202 is provided on one side of the detection housing 201a, the other side of the detection housing 201a is connected to the connecting pipe 105a, four telescopic assemblies 203 are all provided outside the detection housing 201a, the telescopic assembly 203 includes a second sliding sleeve 203a, a sliding rod 203b is slidably connected inside the second sliding sleeve 203a, a plurality of first springs 203c are provided inside the second sliding sleeve 203a, the other end of the second sliding sleeve 203a is connected to the detection housing 201a, the other end of the sliding rod 203b is connected to the sealing housing 204, and a pressure detector is provided inside the sealing housing 204;

[0061] When motor 101a is running, it drives the first connecting block 306a and the second connecting block 306d to rotate via a drive shaft on one side. Since the first connecting block 306a and the second connecting block 306d are externally fixed with spiral blades 306b, the spiral blades 306b can rub against the inner wall of the pipe during rotation. This not only propels the detector forward through friction, but also cleans the inner wall of the pipe and removes impurities adhering to the inner wall, thus improving the environmental performance of the detector.

[0062] A groove 302 is provided on one side of the collection shell 301. A slider 303 is slidably connected in the groove 302. One end of the slider 303 is fixedly connected to an extension plate 304. The extension plate 304 fits against the collection shell 301. Several second springs 305 are fixedly connected in the groove 302. The two ends of the second springs 305 are fixedly connected to the lower part of the inner wall of the groove 302 and the lower part of the slider 303, respectively. The pushing assembly 306 is connected to the drive shaft of the motor 101a. Several collection shells 301 are fixedly connected to the drive shaft of the motor 101a. Outside the shaft, the pushing assembly 306 includes a first connecting block 306a, a ball block 306c fixedly connected to one side of the first connecting block 306a, a spiral blade 306b fixedly connected to the outside of the first connecting block 306a, a second connecting block 306d fixedly connected to the other side of the first connecting block 306a, a ball sleeve 306e fixedly connected to the other side of the second connecting block 306d, the diameter of the ball block 306c being adapted to the diameter of the inner wall of the ball sleeve 306e, and a drive connection between one side of the first connecting block 306a and the drive shaft of the motor 101a.

[0063] In this embodiment: During the detection process, motor 101a starts, which drives fan 101b to run. Fan 101b draws in outside air through intake pipe 106a and discharges the air into the first sliding sleeve 105c through connecting pipe 105a and conduit 105b. The air pressure inside the first sliding sleeve 105c rises rapidly. Simultaneously, the sliding tube 105d inside the first sliding sleeve 105c moves accordingly. Since both the first sliding sleeve 105c and the sliding tube 105d are arc-shaped, the sliding tube 105d pushes the fixing plate 104b to rotate along the first pin shaft 104a during its movement, causing... The pulley 104d fits against the inner wall of the pipe, and the discharged gas pushes the slide rod 203b to slide within the second sliding sleeve 203a, causing the sealing shell 204 to fit against the inner wall of the pipe. The gas is then discharged into the sealing shell 204. This allows the detector to automatically adapt to the different inner diameters of the pipes to be tested during use. Furthermore, the fixing plate 104b and pulley 104d effectively reduce the hard friction between the detector and the pipe, thus reducing energy consumption. At the same time, the sealing shell 204 ensures that the surface of the pipe can be inspected during the detection of underground pipelines.

[0064] Example 3

[0065] Combined with appendix Figure 5 and attached Figure 6 Therefore, we can conclude that:

[0066] A method for using an underground pipeline detector includes the following steps:

[0067] S1. When using this detector, the probe needs to be installed on one side of the detection housing 201a, and then the drive battery of the power assembly 101 needs to be replaced. At this time, the pressure detection device installed inside the sealed housing 204 needs to be checked. After the check and replacement are completed, one end of the detector can be connected to the pull rope and inserted into the pipeline for detection.

[0068] S2. During the detection process, motor 101a starts, which drives fan 101b to run. Fan 101b draws in outside air through air inlet pipe 106a and discharges the air into first sliding sleeve 105c through connecting pipe 105a and conduit 105b. The air pressure in first sliding sleeve 105c rises rapidly. At the same time, sliding tube 105d in first sliding sleeve 105c moves accordingly. Since both first sliding sleeve 105c and sliding tube 105d are arc-shaped, sliding tube 105d pushes fixed plate 104b to rotate along first pin shaft 104a during movement, so that pulley 104d fits against the inner wall of the pipe. At the same time, the discharged gas also pushes sliding rod 203b to slide in second sliding sleeve 203a, so that sealing shell 204 fits against the inner wall of the pipe, and gas is discharged into sealing shell 204.

[0069] S3. When personnel open control valve 202 from the outside, all four control valves 202 will be activated simultaneously, allowing the gas accumulated on the inner wall of the detection housing 201a to be discharged, thereby providing a reaction force for the forward movement of the detector and achieving the effect of pushing the detector to move within the pipeline. When a crack appears on the surface of the pipeline, since the sealing housing 204 is in close contact with the inner wall of the pipeline and the fan 101b continuously discharges gas, if there is a crack on the surface of the pipeline, the gas will be discharged along the crack on the surface of the pipeline, and the pressure detector inside the sealing housing 204 will sound an alarm.

[0070] S4. When the motor 101a is running, the motor 101a will drive the first connecting block 306a and the second connecting block 306d to rotate through the drive shaft on one side. Since the first connecting block 306a and the second connecting block 306d are externally fixedly connected with spiral blades 306b, the spiral blades 306b can rub against the inner wall of the pipe during the rotation.

[0071] S5. When motor 101a is running, it will simultaneously drive the collection shell 301 to rotate, causing the extension plate 304 on the inner wall of the collection shell 301 to move rapidly outward under the action of centrifugal force. At this time, the slider 303 will slide in the groove 302. When the extension plate 304 moves to the limit position, it will fit against the inner wall of the pipe, so that the detector can not only clean the inner wall of the pipe, but also collect the impurities after cleaning, preventing impurities from entering the inner wall of motor 101a or fan 101b. This ensures the cleaning effect of the detector while reducing the damage to motor 101a or fan 101b caused by the entry of impurities and affecting their service life.
