Description

Technical Field

[0001] The present invention relates to the technical field of pipeline inspection equipment, and specifically relates to an industrial pipeline pressure inspection equipment. Background Art

[0002] In the transportation of chemical products and natural gas, pressure pipelines are used for transportation. Since natural gas and chemical products are both dangerous goods, it is necessary to regularly inspect the pressure pipelines to check whether there are corrosion or crack problems in the pressure pipelines, so as to prevent leaks and accidents caused by pipeline defects and avoid damage to life and property and environmental pollution.

[0003] When inspecting the pipeline pressure in the open air, due to factors such as human factors, pipeline size, location, and external environment, when the operator detects the pipeline pressure, operations such as the probe angle and the spacing of pipeline contact will be affected, resulting in non-standard operations. Such operations will cause certain errors in the inspection results, thus affecting the accuracy of the inspection results. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an industrial pipeline pressure inspection equipment, including a digital display panel. A connecting wire is fixedly connected to the outer wall of the digital display panel, and a handheld rod is fixedly connected to the outer wall of the connecting wire. The equipment further includes: An enhancement mechanism, which is fixedly connected to the outer wall of the handheld rod and is used to enhance the coupling between the device and the pipeline; A stabilization mechanism, which is fixedly connected to the outer wall of the enhancement mechanism and is used to assist the operator in controlling the device; An auxiliary mechanism, which is fixedly connected to the outer wall of the enhancement mechanism and is used to enhance the connection between the device and the pipe wall; A return spring is fixedly connected to the outer wall of the handheld rod, and an inspection device is fixedly connected to the outer wall of the return spring. A plurality of lever ones are slidably connected to the outer wall of the inspection device.

[0005] Preferably, the enhancement mechanism includes: An amplification component, whose outer wall is fixedly connected to the outer wall of the handheld rod; A cleaning component, whose outer wall is fixedly connected to the outer wall of the handheld rod.

[0006] Preferably, the stabilization mechanism includes: A connection component, whose outer wall is fixedly connected to the outer wall of the amplification component; A ratchet component, whose inner wall is rotatably connected to the outer wall of the connection component.

[0007] Preferably, the auxiliary mechanism includes: Fixing component, the outer wall of the fixing component is fixedly connected to the outer wall of the cleaning component; Fitting component, the outer wall of the fitting component is fixedly connected to the inner wall of the fixing component.

[0008] Preferably, the magnifying component includes a plurality of second levers rotatably connected to the outer walls of a plurality of first levers, a plurality of third levers rotatably connected to the outer walls of the plurality of second levers, and a plurality of fixing plates rotatably connected to the outer walls of the plurality of third levers; the plurality of fixing plates are grouped in pairs and are respectively rotatably connected to the outer walls of the plurality of first levers and the plurality of second levers.

[0009] Preferably, the cleaning component includes a conical telescopic tube fixedly connected to the outer wall of the hand-held rod, a cleaning channel is opened on the bottom outer wall of the conical telescopic tube, and a metal film tube is fixedly connected to the outer wall of the inspection device.

[0010] During use, the worker holds the handheld rod with his hand and moves the probe device towards the outer wall of the pipeline to be inspected. When the outer wall of the conical telescopic tube contacts the outer wall of the pipeline to be inspected, the conical telescopic tube will start to contract towards the handheld rod, causing the air in the space between the outer wall of the conical telescopic tube and the inner wall of the inspection device to be extruded outward. The extruded air will blow the surface attachments at the contact between the metal film tube and the pipe wall, and the blown attachments will escape from the cleaning channel along with the air flow, maintaining the cleanliness at the contact between the metal film tube and the pipe wall and improving the accuracy of the inspection results. As the device gradually moves towards the pipe wall, the metal film tube will gradually approach the outer wall of the pipeline. When the outer wall of the metal film tube contacts the outer wall of the pipeline, the sliding connection between the third lever and the metal film tube will move accordingly. Since the contact time between the metal film tube and the outer wall of the pipeline is different before and after, the positions of the multiple third levers slidingly connected to its inner wall will be different. Therefore, the metal film tube will closely adhere to the outer wall of the pipeline under the action of the third lever. Since the fixing plates are rotatably connected to the outer walls of the third levers in pairs and are close to the outer wall of the metal film tube, the fixing plate rotatably connected to the outer wall of the second lever is close to the connection between the second lever and the third lever, and the fixing plate rotatably connected to the outer wall of the first lever is close to the connection between the first lever and the second lever. Thus, when the metal film tube receives the echo, it will be conducted to the third lever. Since the position where the third lever rotates is close to the metal film tube, the lever arm between the fixing plate and the metal film tube is smaller than the lever arm between the connection between the second lever and the third lever and the fixing plate. As a result, the vibration received at the connection between the second lever and the third lever is greater than the vibration received at the connection between the third lever and the metal film tube. Similarly, the vibration received at the connection between the first lever and the second lever is greater than the vibration received at the connection between the second lever and the third lever, and the vibration received at the connection between the first lever and the inspection device is greater than the vibration received at the connection between the first lever and the second lever. Finally, the echo vibration received by the inspection device is amplified, which is beneficial to improving the accuracy of the inspection results. Preferably, the connection assembly includes a plurality of connection blocks fixedly connected to the outer wall of the inspection device. A plurality of connecting rods are rotatably connected to the inner walls of the plurality of connection blocks. A plurality of telescopic rods are rotatably connected to the outer walls of the plurality of connecting rods. A plurality of connecting plates are rotatably connected to the outer walls of the plurality of telescopic rods. The outer walls of the plurality of connecting plates are fixedly connected to the inner wall of the conical telescopic tube.

[0011] Preferably, the ratchet assembly includes a plurality of inner wheels fixedly connected to the outer walls of the plurality of connecting rods. A plurality of outer wheels are rotatably connected to the outer walls of the plurality of inner wheels. An arc-shaped plate is rotatably connected to the outer walls of the plurality of inner wheels. A spring is fixedly connected to the outer wall of the arc-shaped plate. The end of the spring far from the arc-shaped plate is fixedly connected to a fixed rod. The outer wall of the fixed rod is fixedly connected to the outer wall of the inner wheel.

[0012] When the handheld rod moves towards the outer wall of the pipeline, the outer wheel will come into contact with the outer wall of the pipeline, causing the outer wheel to move away from the center of the device. When the outer wheel moves away from the center of the device, it will drive the inner wheel rotatably connected to it to move away from the center of the device. The connection point between the connecting rod and the inner wheel will also move along with the inner wheel. At this time, the connecting rod will rotate around the rotating connection point between the telescopic rod and the connecting rod, causing the telescopic rod to extend out of the conical telescopic tube. Further, the rotation of the connecting rod will cause the connecting block to move towards the pipe wall, thereby driving the inspection device and the metal film tube towards the outer wall of the pipeline. When moving to the required position, the operator's force on the handheld rod towards the outer wall of the pipeline will decrease and gradually disappear. At this time, due to the action of the telescopic rod, the connecting rod will move towards the center of the device. Since the arc-shaped plate will hold the outer wheel at the contact position of the arc-shaped plate under the action of the spring at this time, and due to the internal structure of the outer wheel, the outer wheel cannot pass through the contact position with the arc-shaped plate, which further inhibits the outer wheel from moving towards the center position of the device. At this time, due to the interaction between the friction between the outer wheel and the outer wall of the pipeline and the pulling force of the telescopic rod on the connecting rod, it is difficult for the device to change the angle with the pipe wall, thereby reducing the influence of human factors on the test results; Preferably, the fixing component includes a plurality of fixing blocks fixedly connected to the outer wall of the conical telescopic tube. A piston rod is rotatably connected to the inner walls of the plurality of fixing blocks, and a piston plate is fixedly connected to the outer wall of the piston rod.

[0013] Preferably, the fitting component includes a plurality of connecting shafts fixedly connected to the inner wall of the piston plate. A plurality of one-way plates are rotatably connected to the outer walls of the plurality of connecting shafts, and a sleeve is slidably connected to the outer wall of the piston plate.

[0014] When the device moves towards the outer wall of the pipeline, it will drive the auxiliary mechanism to also contact the outer wall of the pipeline. When the outer wall of the sleeve contacts the outer wall of the pipeline, when the device continues to move, it will cause the piston rod to drive the piston plate to move towards the outer wall of the pipeline. At this time, a plurality of one-way plates arranged on the inner wall of the piston plate will cause the air between the piston plate and the outer wall of the pipeline to be squeezed, so that the air will escape from the one-way plates due to the squeezing of the air. Since a coupling agent will be sprayed on the outer wall of the pipeline when testing the pipeline pressure, when the sleeve contacts the outer wall of the pipeline, the coupling agent will seal the contact position between the sleeve and the outer wall of the pipeline. Thus, after the air between the sleeve and the piston plate escapes, it is difficult for the piston rod to drive the piston plate to move away from the outer wall of the pipeline, thereby enhancing the connection between the probe device and the outer wall of the pipeline and weakening the influence of the vibration of the pipeline during use on the probe.

[0015] The present invention has the following beneficial effects: (1)To solve the problem that the accuracy of the inspection result is affected by human factors when actually inspecting the pipeline pressure, the present invention is provided with a stabilizing mechanism. When the handheld rod moves towards the outer wall of the pipeline, the outer wheel will contact the outer wall of the pipeline, causing the outer wheel to move away from the center of the device. At this time, the inner wheel rotatably connected to it will be driven to move away from the center of the device, and further, the telescopic rod will extend out of the conical telescopic tube. Furthermore, the rotation of the connecting rod will cause the connecting block to move towards the pipe wall, thereby driving the inspection device and the metal film tube to move towards the outer wall of the pipeline. When moving to the required position, the operator's force will gradually disappear, and the connecting rod will move towards the center of the device due to the action of the telescopic rod. At this time, since the arc plate will hold the outer wheel at the contact position of the arc plate under the action of the spring, at this time, due to the interaction between the friction between the outer wheel and the pipeline outer wall and the pulling force of the telescopic rod on the connecting rod, it is difficult for the device to change the angle with the pipe wall, thus reducing the influence of human factors on the inspection result; (2)To solve the problem that the received echo will be weakened due to various factors that the acoustic wave inspection device is vulnerable to, the present invention is provided with an amplification component. The fixed plates are arranged in pairs and rotatably connected to the outer wall of the lever three and close to the outer wall of the metal film tube. The fixed plate rotatably connected to the outer wall of the lever two is close to the connection between the lever two and the lever three, and the fixed plate rotatably connected to the outer wall of the lever one is close to the connection between the lever one and the lever two. Since the rotation position of the lever three is close to the metal film tube, the vibration received at the connection between the lever two and the lever three is greater than the vibration received at the connection between the lever three and the metal film tube. Finally, the vibration of the echo received by the inspection device is amplified, which is beneficial to improving the accuracy of the inspection result; (3)To solve the problem that the vibration during pipeline operation may cause unstable probe coupling or interfere with instrument signal acquisition, which is likely to cause data distortion, the present invention is provided with an auxiliary mechanism. When the device moves to a certain position, the piston rod will drive the piston plate to move towards the outer wall of the pipeline. At this time, several one-way plates arranged on the inner wall of the piston plate will cause the air between the piston plate and the outer wall of the pipeline to be squeezed out. Since coupling agent will be sprayed onto the outer wall of the pipeline when inspecting the pipeline pressure, when the sleeve contacts the outer wall of the pipeline, the coupling agent will seal the contact position between the sleeve and the outer wall of the pipeline. Furthermore, after the air between the sleeve and the piston plate escapes, it is difficult for the piston rod to drive the piston plate to move away from the outer wall of the pipeline, thereby enhancing the connection between the probe device and the outer wall of the pipeline and weakening the influence of the vibration of the pipeline during use on the probe; (4) In order to solve the problem that sundries exist between the pipeline and the probe, resulting in inaccurate detection results, the present invention is provided with a cleaning component. When the outer wall of the conical telescopic pipe contacts the outer wall of the pipeline to be inspected, the conical telescopic pipe will start to contract towards the handheld rod, causing the air in the space between the conical telescopic pipe and the inner wall of the inspection device to be extruded outward. The extruded air will blow the surface attachments at the contact between the metal film pipe and the pipe wall, and the blown attachments will escape from the cleaning channel along with the air flow, maintaining the cleanliness at the contact between the metal film pipe and the pipe wall and improving the accuracy of the inspection results.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Example 1, please refer to Figures 1 - 10 , the present invention is an industrial pipeline pressure inspection device, including a digital display panel 13. A connecting wire 14 is fixedly connected to the outer wall of the digital display panel 13, and a handheld rod 15 is fixedly connected to the outer wall of the connecting wire 14. It further includes: Enhancement mechanism 1, which is fixedly connected to the outer wall of the handheld rod 15 and is used to enhance the coupling between the device and the pipeline; Stabilization mechanism 2, which is fixedly connected to the outer wall of the enhancement mechanism 1 and is used to assist manual control of the device; Auxiliary mechanism 3, which is fixedly connected to the outer wall of the enhancement mechanism 1 and is used to enhance the connection between the device and the pipe wall; A reset spring 111 is fixedly connected to the outer wall of the handheld rod 15, and an inspection device 112 is fixedly connected to the outer wall of the reset spring 111. A plurality of lever 1s 113 are slidably connected to the outer wall of the inspection device 112.

[0021] The enhancement mechanism 1 includes: Amplification component 11, whose outer wall is fixedly connected to the outer wall of the handheld rod 15; Cleaning component 12, whose outer wall is fixedly connected to the outer wall of the handheld rod 15.

[0022] The stabilization mechanism 2 includes: Connecting component 21, the outer wall of the connecting component 21 is fixedly connected to the outer wall of the amplifying component 11; Ratchet component 22, the inner wall of the ratchet component 22 is rotatably connected to the outer wall of the connecting component 21.

[0023] The auxiliary mechanism 3 includes: Fixing component 31, the outer wall of the fixing component 31 is fixedly connected to the outer wall of the cleaning component 12; Fitting component 32, the outer wall of the fitting component 32 is fixedly connected to the inner wall of the fixing component 31.

[0024] The amplifying component 11 includes a plurality of lever twos 114 rotatably connected to the outer walls of a plurality of lever ones 113, a plurality of lever threes 115 are rotatably connected to the outer walls of the plurality of lever twos 114, and a plurality of fixing plates 116 are rotatably connected to the outer walls of the plurality of lever threes 115; the plurality of fixing plates 116 are grouped in pairs and are respectively rotatably connected to the outer walls of the plurality of lever ones 113 and the plurality of lever twos 114.

[0025] The cleaning component 12 includes a conical telescopic tube 121 fixedly connected to the outer wall of the handheld rod 15, a cleaning channel 122 is provided on the bottom outer wall of the conical telescopic tube 121, and a metal film tube 123 is fixedly connected to the outer wall of the inspection device 112.

[0026] During use, the worker will hold the handheld rod 15 and move the probe device towards the outer wall of the pipeline to be inspected. When the outer wall of the conical telescopic tube 121 comes into contact with the outer wall of the pipeline to be inspected, the conical telescopic tube 121 will start to contract towards the handheld rod 15, causing the air in the inner wall space between the conical telescopic tube 121 and the inspection device 112 to be extruded outwards. The extruded air will blow the surface attachments at the contact between the metal film tube 123 and the pipe wall, and the blown attachments will escape from the cleaning channel 122 along with the air flow, maintaining the cleanliness at the contact between the metal film tube 123 and the pipe wall and improving the accuracy of the inspection results. As the device gradually moves towards the pipe wall, the metal film tube 123 will gradually approach the outer wall of the pipeline. When the outer wall of the metal film tube 123 contacts the outer wall of the pipeline, the sliding connection between the third lever 115 and the metal film tube 123 will move accordingly. Since the contact time between the metal film tube 123 and the outer wall of the pipeline is different before and after, the positions of the multiple third levers 115 slidingly connected to its inner wall are different. Therefore, the metal film tube 123 will closely adhere to the outer wall of the pipeline under the action of the third lever 115. Since the fixing plates 116 are rotatably connected to the outer walls of the third levers 115 in pairs and are close to the outer wall of the metal film tube 123, the fixing plate 116 rotatably connected to the outer wall of the second lever 114 is close to the connection between the second lever 114 and the third lever 115, and the fixing plate 116 rotatably connected to the outer wall of the first lever 113 is close to the connection between the first lever 113 and the second lever 114. Thus, when the metal film tube 123 receives the echo, it will be conducted to the third lever 115. Since the position where the third lever 115 rotates is close to the metal film tube 123, the force arm between the fixing plate 116 and the metal film tube 123 is smaller than the force arm between the second lever 114 and the third lever 115 connected to the fixing plate 116. Furthermore, the vibration received at the connection between the second lever 114 and the third lever 115 is greater than the vibration received at the connection between the third lever 115 and the metal film tube 123. Similarly, the vibration received at the connection between the first lever 113 and the second lever 114 is greater than the vibration received at the connection between the second lever 114 and the third lever 115, and the vibration received at the connection between the first lever 113 and the inspection device 112 is greater than the vibration received at the connection between the first lever 113 and the second lever 114. Finally, the echo vibration received by the inspection device 112 is amplified, which is beneficial to improving the accuracy of the inspection results; Embodiment 2. Please refer to Figures 3 - 12 , based on Example 1, the connection component 21 of the industrial pipeline pressure inspection equipment of the present invention includes a plurality of connection blocks 211 fixedly connected to the outer wall of the inspection device 112. A plurality of connecting rods 212 are rotatably connected to the inner walls of the plurality of connection blocks 211. A plurality of telescopic rods 213 are rotatably connected to the outer walls of the plurality of connecting rods 212. A plurality of connecting plates 214 are rotatably connected to the outer walls of the plurality of telescopic rods 213; the outer walls of the plurality of connecting plates 214 are fixedly connected to the inner wall of the conical telescopic tube 121.

[0027] The ratchet assembly 22 includes a plurality of inner wheels 221 fixedly connected to the outer walls of a plurality of connecting rods 212. A plurality of outer wheels 222 are rotatably connected to the outer walls of the plurality of inner wheels 221. An arc-shaped plate 223 is rotatably connected to the outer walls of the plurality of inner wheels 221. A spring 224 is fixedly connected to the outer wall of the arc-shaped plate 223. One end of the spring 224 away from the arc-shaped plate 223 is fixedly connected to a fixing rod 225; the outer wall of the fixing rod 225 is fixedly connected to the outer wall of the inner wheel 221.

[0028] When the handheld rod 15 moves towards the outer wall of the pipeline, the outer wheel 222 will contact the outer wall of the pipeline, causing the outer wheel 222 to move away from the center of the device. When the outer wheel 222 moves away from the center of the device, it will drive the inner wheel 221 rotatably connected to it to move away from the center of the device. The connection part between the connecting rod 212 and the inner wheel 221 will also move along with the inner wheel 221. At this time, the connecting rod 212 will rotate around the rotation connection part between the telescopic rod 213 and the connecting rod 212, causing the telescopic rod 213 to extend out of the conical telescopic tube 121. Further, the rotation of the connecting rod 212 will cause the connection block 211 to move towards the pipe wall, thereby driving the inspection device 112 and the metal film tube 123 to move towards the outer wall of the pipeline. When moving to the required position, the force exerted by the operator on the handheld rod 15 towards the outer wall of the pipeline will decrease and gradually disappear. At this time, the connecting rod 212 will move towards the center of the device due to the action of the telescopic rod 213. And because at this time the arc-shaped plate 223 will, under the action of the spring 224, clamp the outer wheel 222 at the contact position of the arc-shaped plate 223, due to the internal structure of the outer wheel 222, the outer wheel 222 cannot pass through the contact position with the arc-shaped plate 223, thereby further inhibiting the outer wheel 222 from moving towards the center position of the device. At this time, due to the interaction between the friction force between the outer wheel 222 and the outer wall of the pipeline and the pulling force of the telescopic rod 213 on the connecting rod 212, the device is difficult to change the angle with the pipe wall, thereby reducing the influence of human factors on the inspection results; the fixing assembly 31 includes a plurality of fixing blocks 311 fixedly connected to the outer wall of the conical telescopic tube 121. A piston rod 312 is rotatably connected to the inner walls of the plurality of fixing blocks 311. A piston plate 313 is fixedly connected to the outer wall of the piston rod 312.

[0029] The fitting assembly 32 includes a plurality of connecting shafts 321 fixedly connected to the inner wall of the piston plate 313. A plurality of one-way plates 322 are rotatably connected to the outer walls of the plurality of connecting shafts 321. A sleeve 323 is slidably connected to the outer wall of the piston plate 313.

[0030] When the device moves towards the outer wall of the pipeline, it will drive the auxiliary mechanism 3 to also contact the outer wall of the pipeline. After the outer wall of the sleeve 323 contacts the outer wall of the pipeline, when the device continues to move, the piston rod 312 will drive the piston plate 313 to move towards the outer wall of the pipeline. At this time, several one-way plates 322 arranged on the inner wall of the piston plate 313 will be squeezed due to the air between the piston plate 313 and the outer wall of the pipeline, so that the one-way plates 322 will overflow air due to the extrusion of the air, and since a coupling agent will be sprayed on the outer wall of the pipeline when inspecting the pipeline pressure, when the sleeve 323 contacts the outer wall of the pipeline, the coupling agent will seal the contact position between the sleeve 323 and the outer wall of the pipeline. Furthermore, after the air between the sleeve 323 and the piston plate 313 escapes, it is difficult for the piston rod 312 to drive the piston plate 313 to move away from the outer wall of the pipeline, thereby enhancing the connection between the probe device and the outer wall of the pipeline and weakening the influence of the vibration of the pipeline during use on the probe.

[0031] A specific application of this embodiment is as follows: When in use, the worker holds the handheld rod 15 and moves the probe device towards the outer wall of the pipeline to be inspected. When the outer wall of the conical telescopic tube 121 comes into contact with the outer wall of the pipeline to be inspected, the conical telescopic tube 121 will start to contract towards the handheld rod 15, causing the air in the inner wall space between the conical telescopic tube 121 and the inspection device 112 to be extruded outward. The extruded air will blow the surface attachments at the contact position between the metal film tube 123 and the pipe wall, and the blown attachments will escape from the cleaning channel 122 along with the air flow, maintaining the cleanliness at the contact position between the metal film tube 123 and the pipe wall and improving the accuracy of the inspection results. As the handheld rod 15 moves towards the outer wall of the pipeline, the outer wheel 222 will come into contact with the outer wall of the pipeline, causing the outer wheel 222 to move away from the center of the device. When the outer wheel 222 moves away from the center of the device, it will drive the inner wheel 221 rotatably connected to it to move away from the center of the device. The connection position between the connecting rod 212 and the inner wheel 221 will also move with the inner wheel 221. At this time, the connecting rod 212 will rotate around the rotation connection position between the telescopic rod 213 and the connecting rod 212, causing the telescopic rod 213 to extend outward from the conical telescopic tube 121. Further, the rotation of the connecting rod 212 will cause the connection block 211 to move towards the pipe wall, thereby driving the inspection device 112 and the metal film tube 123 to move towards the outer wall of the pipeline. When moving to the required position, the force exerted by the worker on the handheld rod 15 towards the outer wall of the pipeline will decrease and gradually disappear. At this time, due to the action of the telescopic rod 213, the connecting rod 212 will move towards the center of the device. And because at this time the arc-shaped plate 223 will hold the outer wheel 222 at the contact position of the arc-shaped plate 223 under the action of the spring 224, and due to the internal structure of the outer wheel 222, the outer wheel 222 cannot pass through the contact position with the arc-shaped plate 223, which further inhibits the outer wheel 222 from moving towards the center position of the device. At this time, due to the interaction between the friction force between the outer wheel 222 and the pipe wall and the pulling force of the telescopic rod 213 on the connecting rod 212, it is difficult for the device to change the angle with the pipe wall, thereby reducing the influence on the inspection due to human factors. As the device gradually moves towards the pipe wall, the metal film tube 123 will gradually approach the outer wall of the pipeline. When the outer wall of the metal film tube 123 comes into contact with the outer wall of the pipeline, the sliding connection position between the third lever 115 and the metal film tube 123 will move accordingly. And because the contact time between the metal film tube 123 and the outer wall of the pipeline is different before and after, the positions where the multiple third levers 115 slidably connected to its inner wall move are different. Therefore, the metal film tube 123 will closely adhere to the outer wall of the pipeline under the action of the third lever 115;Since the fixing plates 116 are rotatably connected to the outer wall of the third lever 115 in pairs and are close to the outer wall of the metal film tube 123, the fixing plate 116 rotatably connected to the outer wall of the second lever 114 is close to the connection between the second lever 114 and the third lever 115, and the fixing plate 116 rotatably connected to the outer wall of the first lever 113 is close to the connection between the first lever 113 and the second lever 114. Therefore, when the metal film tube 123 receives an echo, it will be conducted to the third lever 115. Since the rotation position of the third lever 115 is close to the metal film tube 123, the lever arm between the fixing plate 116 and the metal film tube 123 is smaller than the lever arm between the second lever 114 and the third lever 115 connected to the fixing plate 116. As a result, the vibration received at the connection between the second lever 114 and the third lever 115 is greater than the vibration received at the connection between the third lever 115 and the metal film tube 123. Similarly, the vibration received at the connection between the first lever 113 and the second lever 114 is greater than the vibration received at the connection between the second lever 114 and the third lever 115, and the vibration received at the connection between the first lever 113 and the testing device 112 is greater than the vibration received at the connection between the first lever 113 and the second lever 114. Finally, the echo vibration received by the testing device 112 is amplified, which is beneficial to improving the accuracy of the test result. When the device moves towards the outer wall of the pipeline, it will drive the auxiliary mechanism 3 to also contact the outer wall of the pipeline. When the outer wall of the sleeve 323 contacts the outer wall of the pipeline, when the device continues to move, the piston rod 312 will drive the piston plate 313 to move towards the outer wall of the pipeline. At this time, several one-way plates 322 provided on the inner wall of the piston plate 313 will cause the air between the piston plate 313 and the outer wall of the pipeline to be squeezed, so that the one-way plates 322 will cause the air to overflow from the one-way plates 322 due to the air squeeze. Since a coupling agent is sprayed on the outer wall of the pipeline when testing the pipeline pressure, when the sleeve 323 contacts the outer wall of the pipeline, the coupling agent will seal the contact position between the sleeve 323 and the outer wall of the pipeline. Therefore, after the air between the sleeve 323 and the piston plate 313 escapes, it is difficult for the piston rod 312 to drive the piston plate 313 to move away from the outer wall of the pipeline, thereby enhancing the connection between the probe device and the outer wall of the pipeline and weakening the influence of the vibration of the pipeline during use on the probe.;
