The present invention relates to the technical field of pipeline inspection equipment, specifically to an industrial pipeline pressure inspection equipment connection assembly including a plurality of connection blocks fixedly connected to the outer wall of the inspection device, a plurality of connection rods rotatably connected to the inner walls of the plurality of connection blocks, a plurality of telescopic rods rotatably connected to the outer walls of the plurality of connection rods, and a plurality of connection plates rotatably connected to the outer walls of the plurality of telescopic rods. When the hand-held rod moves toward the outer wall of the pipeline, it will drive the inspection device and the metal film tube to move toward the outer wall of the pipeline. When it moves to the required position, the force applied by the operator to the pipe wall will gradually disappear. At this time, the arc plate will clamp the outer wheel in the contact position of the arc plate under the action of the spring.

[0002] Pressure pipelines are used in the transportation of chemical products and natural gas. Both natural gas and chemical products are dangerous goods, so pressure pipelines need to be inspected regularly to check whether there are corrosion or cracks in the pressure pipelines to prevent leakage and accidents caused by defects in the pressure pipelines, avoid damage to life and property and pollution to the environment.

[0003] When inspecting pipeline pressure in the open air, due to human factors, pipeline size, location, external environment and other factors, the operator may use the probe angle, pipeline contact spacing and other operations when testing the pipeline pressure, resulting in non-standard operations. This operation will cause certain errors in the inspection results, thereby 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 testing device, comprising a digital display panel, a connecting line fixedly connected to the outer wall of the digital display panel, a handheld rod fixedly connected to the outer wall of the connecting line, and further comprising:

[0005] A reinforcing mechanism, the reinforcing mechanism is fixedly connected to the outer wall of the hand-held rod and is used to enhance the coupling between the device and the pipeline;

[0006] A stabilizing mechanism, the stabilizing mechanism is fixedly connected to the outer wall of the reinforcing mechanism and is used to assist manual control of the device;

[0007] An auxiliary mechanism, the auxiliary mechanism is fixedly connected to the outer wall of the reinforcing mechanism, and the auxiliary mechanism is used to strengthen the connection between the device and the pipe wall;

[0008] The outer wall of the hand-held rod is fixedly connected with a reset spring, the outer wall of the reset spring is fixedly connected with a testing device, and the outer wall of the testing device is slidably connected with a plurality of levers.

[0009] Preferably, the reinforcement mechanism comprises:

[0010] A magnifying assembly, wherein the outer wall of the magnifying assembly is fixedly connected to the outer wall of the hand-held rod;

[0011] A cleaning component, wherein the outer wall of the cleaning component is fixedly connected to the outer wall of the hand-held rod.

[0012] Preferably, the stabilizing mechanism comprises:

[0013] A connecting component, wherein the outer wall of the connecting component is fixedly connected to the outer wall of the amplifying component;

[0014] A ratchet assembly, wherein the inner wall of the ratchet assembly is rotatably connected to the outer wall of the connecting assembly.

[0015] Preferably, the auxiliary mechanism includes:

[0016] A fixing component, wherein the outer wall of the fixing component is fixedly connected to the outer wall of the cleaning component;

[0017] The fitting component has an outer wall fixedly connected to the inner wall of the fixing component.

[0018] Preferably, the amplification assembly includes several lever twos rotatably connected to the outer walls of several lever ones, several lever threes rotatably connected to the outer walls of several lever twos, and several fixed plates rotatably connected to the outer walls of several lever threes; several fixed plates are grouped in pairs and rotatably connected to the outer walls of several lever ones and several lever twos respectively.

[0019] Preferably, the cleaning assembly includes a conical telescopic tube fixedly connected to the outer wall of the handheld 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.

[0020] When in use, the worker will hold the handheld rod and move the probe device toward the outer wall of the pipe that needs to be inspected. When the outer wall of the conical telescopic tube contacts the outer wall of the pipe that needs to be inspected, the conical telescopic tube will begin to shrink toward the handheld rod, so that the air in the space between the conical telescopic tube and the inner wall of the inspection device is squeezed outward, and the squeezed air will blow the surface attachments at the contact point between the metal film tube and the pipe wall. The blown attachments will escape from the cleaning channel with the flow of air, thereby maintaining the cleanliness of the contact point between the metal film tube and the pipe wall and improving the accuracy of the inspection results. As the device gradually moves toward the pipe wall When the metal film tube moves, it will gradually approach the outer wall of the pipe. When the outer wall of the metal film tube contacts the outer wall of the pipe, the sliding connection between lever three and the metal film tube will move accordingly. Since the contact time between the metal film tube and the outer wall of the pipe is different, the positions of the multiple levers three slidingly connected at the inner wall are different. Therefore, the metal film tube will be tightly attached to the outer wall of the pipe under the action of lever three. Since the fixed plates are rotated in pairs and connected to the outer wall of lever three and close to the outer wall of the metal film tube, the fixed plate rotated and connected at the outer wall of lever two is close to the connection between lever two and lever three. The fixed plate connected to the outer wall of lever one is rotated close to the connection between lever one and lever two, so that the metal film tube will transmit the echo to lever three when receiving it. Since the rotation position of lever three is close to the metal film tube, the force arm between the fixed plate and the metal film tube will be smaller than the force arm between the connection between lever two and lever three and the fixed plate, and the vibration received by the connection between lever two and lever three will be greater than the vibration received by the connection between lever three and the metal film tube. Similarly, the vibration received by the connection between lever one and lever two will be greater than the vibration received by the connection between lever two and lever three. The vibration received at the connection between lever one and the inspection device will be greater than that received at the connection between lever one and lever two, and ultimately, the echo vibration received by the inspection device will be amplified, which is beneficial to improving the accuracy of the inspection results; preferably, the connecting assembly includes several connecting blocks fixedly connected to the outer wall of the inspection device, several connecting blocks are rotatably connected to several connecting rods at the inner walls, several connecting rods are rotatably connected to several telescopic rods at the outer walls, and several telescopic rods are rotatably connected to several connecting plates at the outer walls; the outer walls of several connecting plates are fixedly connected to the inner wall of the conical telescopic tube.

[0021] Preferably, the ratchet assembly includes several inner wheels fixedly connected to the outer walls of several connecting rods, several outer wheels are rotatably connected to the outer walls of several inner wheels, arc-shaped plates are rotatably connected to the outer walls of several inner wheels, a spring is fixedly connected to the outer wall of the arc-shaped plate, and one end of the spring away from the arc-shaped plate is fixedly connected to the fixing rod; the outer wall of the fixing rod is fixedly connected to the outer wall of the inner wheel.

[0022] As the hand-held rod moves toward the outer wall of the pipe, the outer wheel will contact the outer wall of the pipe, 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 connected to it to move away from the center of the device, and the connection between the connecting rod and the inner wheel will also move with the inner wheel. At this time, the connecting rod will rotate around the connection between the telescopic rod and the connecting rod, causing the telescopic rod to extend out of the tapered telescopic tube. Further, the rotation of the connecting rod will cause the connecting block to move toward the pipe wall, thereby driving the inspection device and the metal film tube to move toward the outer wall of the pipe. When it moves to the desired position, the operator's force on the hand-held rod toward the outer wall of the pipe will decrease and gradually disappear. At this time, the connecting rod will be The action of the telescopic rod causes the connecting rod to move toward the center of the device. At this time, the arc plate will clamp the outer wheel in the contact position of the arc plate under the action of the spring. Due to the internal structure of the outer wheel, the outer wheel cannot pass through the contact position with the arc plate, which in turn inhibits the outer wheel from moving toward the center of the device. At this time, due to the interaction between the friction between the outer wheel and the outer wall of the pipe 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 inspection results; preferably, the fixing assembly includes several fixed blocks fixedly connected to the outer wall of the tapered telescopic tube, the inner walls of the several fixed blocks are rotatably connected to the piston rod, and the outer wall of the piston rod is fixedly connected to the piston plate.

[0023] Preferably, the fitting assembly 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.

[0024] When the device moves toward the outer wall of the pipe, it will drive the auxiliary mechanism to contact the outer wall of the pipe. When the outer wall of the sleeve contacts the outer wall of the pipe, when the device continues to move, the piston rod will drive the piston plate to move toward the outer wall of the pipe. At this time, several one-way plates arranged on the inner wall of the piston plate will be squeezed due to the air between the piston plate and the outer wall of the pipe, so that the air will escape from the one-way plates due to the squeezing of the air. Since a coupling agent is sprayed on the outer wall of the pipe when testing the pipeline pressure, the coupling agent will seal the contact position between the sleeve and the outer wall of the pipe when the sleeve contacts the outer wall of the pipe, and then 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 pipe, thereby strengthening the connection between the probe device and the outer wall of the pipe and reducing the influence of the vibration of the pipeline during use on the probe.

[0025] The present invention has the following beneficial effects:

[0026] (1) In order to solve the problem of human factors affecting the accuracy of the test results when actually testing the pipeline pressure, the present invention is provided with a stabilizing mechanism. When the hand-held rod moves toward 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, and at this time, the inner wheel connected to the hand-held rod will move away from the center of the device, and then the telescopic rod will extend outward from the conical telescopic tube. Further, the rotation of the connecting rod will cause the connecting block to move toward the pipe wall, thereby driving the test device and the metal film tube to move toward the outer wall of the pipe. When it moves to the required position, the force of the operator will gradually disappear, and the connecting rod will move toward the center of the device due to the action of the telescopic rod. At this time, the arc plate will clamp the outer wheel in 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 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 between it and the pipe wall, thereby reducing the influence of human factors on the test results.

[0027] (2) In order to solve the problem that the acoustic wave inspection device is susceptible to various factors and thus the received echo is weakened, the present invention is provided with an amplification component, and the fixed plates are arranged in pairs and are rotatably connected to the outer wall of lever three and close to the outer wall of the metal film tube. The fixed plate rotatably connected to the outer wall of lever two is close to the connection between lever two and lever three, and the fixed plate rotatably connected to the outer wall of lever one is close to the connection between lever one and lever two. Since the rotation position of lever three is close to the metal film tube, the vibration received by the connection between lever two and lever three is greater than the vibration received by the connection between lever three and the metal film tube. Finally, the echo vibration received by the inspection device is amplified, which is conducive to improving the accuracy of the inspection result.

[0028] (3) In order to solve the problem that vibration during pipeline operation may cause unstable probe coupling or interfere with instrument signal acquisition, which may easily 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 toward the outer wall of the pipeline. At this time, the air between the piston plate and the outer wall of the pipeline will be squeezed out by several one-way plates provided on the inner wall of the piston plate. When the pipeline pressure is tested, the coupling agent will be sprayed on the outer wall of the pipeline. 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. As a result, 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 strengthening the connection between the probe device and the outer wall of the pipeline and reducing the influence of the vibration of the pipeline on the probe during use.

[0029] (4) In order to solve the problem of inaccurate detection results caused by the presence of debris between the pipeline and the probe, the present invention is provided with a cleaning component. When the outer wall of the conical telescopic tube contacts the outer wall of the pipeline to be inspected, the conical telescopic tube will begin to shrink toward the hand-held rod, so that the air in the space between the conical telescopic tube and the inner wall of the inspection device is squeezed outward. The squeezed air will blow the surface attachments at the contact point between the metal film tube and the pipe wall. The blown attachments will escape from the cleaning channel with the flow of air, thereby maintaining the cleanliness of the contact point between the metal film tube and the pipe wall and improving the accuracy of the inspection results.

DETAILED DESCRIPTION

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] For example 1, please refer to Figures 1-10 The present invention is an industrial pipeline pressure testing device, comprising a digital display panel 13, a connecting line 14 fixedly connected to the outer wall of the digital display panel 13, a handheld rod 15 fixedly connected to the outer wall of the connecting line 14, and further comprising:

[0047] A reinforcing mechanism 1 is fixedly connected to the outer wall of the hand-held rod 15 and is used to enhance the coupling between the device and the pipeline;

[0049] Auxiliary mechanism 3, the auxiliary mechanism 3 is fixedly connected to the outer wall of the reinforcing mechanism 1, and the auxiliary mechanism 3 is used to strengthen the connection between the device and the pipe wall;

[0050] A return spring 111 is fixedly connected to the outer wall of the hand-held rod 15, a testing device 112 is fixedly connected to the outer wall of the return spring 111, and a plurality of levers 113 are slidably connected to the outer wall of the testing device 112.

[0051] The reinforcement mechanism 1 comprises:

[0052] Amplifying component 11, wherein the outer wall of the amplifying component 11 is fixedly connected to the outer wall of the hand-held rod 15;

[0053] The cleaning component 12 has an outer wall fixedly connected to the outer wall of the hand-held rod 15 .

[0054] The stabilizing mechanism 2 includes:

[0055] A connecting component 21, wherein the outer wall of the connecting component 21 is fixedly connected to the outer wall of the amplifying component 11;

[0056] The ratchet assembly 22 has an inner wall that is rotatably connected to the outer wall of the connecting assembly 21 .

[0057] Auxiliary mechanism 3 includes:

[0058] A fixing assembly 31, wherein the outer wall of the fixing assembly 31 is fixedly connected to the outer wall of the cleaning assembly 12;

[0059] The fitting component 32 has its outer wall fixedly connected to the inner wall of the fixing component 31 .

[0060] The amplifying assembly 11 includes a plurality of levers 2 114 rotatably connected to the outer walls of a plurality of levers 113, a plurality of levers 3 115 rotatably connected to the outer walls of a plurality of levers 2 114, and a plurality of fixed plates 116 rotatably connected to the outer walls of a plurality of levers 3 115; the plurality of fixed plates 116 are grouped in pairs and rotatably connected to the outer walls of the plurality of levers 1 113 and the plurality of levers 2 114.

[0061] The cleaning assembly 12 includes a tapered telescopic tube 121 fixedly connected to the outer wall of the handheld rod 15 , a cleaning channel 122 is opened on the bottom outer wall of the tapered telescopic tube 121 , and a metal film tube 123 is fixedly connected to the outer wall of the inspection device 112 .

[0062] When in use, the worker will hold the hand-held rod 15 and move the probe device toward the outer wall of the pipe that needs to be inspected. When the outer wall of the conical telescopic tube 121 contacts the outer wall of the pipe that needs to be inspected, the conical telescopic tube 121 will begin to shrink toward the hand-held rod 15, so that the air in the space between the conical telescopic tube 121 and the inner wall of the inspection device 112 is squeezed outward, and the squeezed air will blow the surface attachments at the contact point between the metal film tube 123 and the pipe wall. The blown attachments will escape from the cleaning channel 122 with the flow of air, thereby maintaining the cleanliness of the contact point between the metal film tube 123 and the pipe wall and improving the cleaning efficiency. The accuracy of the test results; as the device gradually moves toward the pipe wall, the metal film tube 123 will gradually approach the outer wall of the pipe. When the outer wall of the metal film tube 123 contacts the outer wall of the pipe, the sliding connection between the lever three 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 pipe is different, the positions of the multiple lever three 115 slidingly connected on the inner wall are different. Therefore, the metal film tube 123 will be tightly attached to the outer wall of the pipe under the action of the lever three 115; since the fixed plates 116 are rotated in pairs to connect the lever three 115 The outer wall of the lever 114 is close to the outer wall of the metal film tube 123, and the fixed plate 116 is rotated and connected to the outer wall of the lever 113 near the connection between the lever 113 and the lever 114. The fixed plate 116 is rotated and connected to the outer wall of the lever 113 near the connection between the lever 113 and the lever 2 114, so that the metal film tube 123 transmits the echo to the lever 3 115 when receiving the echo. Since the position of the lever 3 115 is close to the metal film tube 123, the force arm between the fixed plate 116 and the metal film tube 123 is smaller than the force arm between the lever 2 114 and the lever 3 115 connected to the fixed plate 116. The force arm between the fixed plate 116 causes the vibration at the connection between the second lever 114 and the third lever 115 to be greater than the vibration at the connection between the third lever 115 and the metal film tube 123. Similarly, the vibration at the connection between the first lever 113 and the second lever 114 is greater than the vibration at the connection between the second lever 114 and the third lever 115. The vibration at the connection between the first lever 113 and the inspection device 112 is greater than the vibration at the connection between the first lever 113 and the second lever 114. Ultimately, the echo vibration received by the inspection device 112 is amplified, which is conducive to improving the accuracy of the inspection result.

[0063] For example 2, please refer to Figure 3-Figure 12 The present invention is an industrial pipeline pressure testing equipment based on Example 1. The connecting assembly 21 includes a plurality of connecting blocks 211 fixedly connected to the outer wall of the testing device 112, a plurality of connecting rods 212 rotatably connected to the inner walls of the plurality of connecting blocks 211, a plurality of telescopic rods 213 rotatably connected to the outer walls of the plurality of connecting rods 212, and a plurality of connecting plates 214 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.

[0064] The ratchet assembly 22 includes several inner wheels 221 fixedly connected to the outer walls of several connecting rods 212, several outer wheels 222 are rotatably connected to the outer walls of several inner wheels 221, and arc-shaped plates 223 are rotatably connected to the outer walls of several inner wheels 221. A spring 224 is fixedly connected to the outer wall of the arc-shaped plate 223, and the 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.

[0065] As the handheld rod 15 moves toward the outer wall of the pipe, the outer wheel 222 will contact the outer wall of the pipe, 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 connected to it to move away from the center of the device, and the connection 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 telescopic rod 213 and the rotating connection between the connecting rod 212, causing the telescopic rod 213 to extend out of the tapered telescopic tube 121. Further, the rotation of the connecting rod 212 will cause the connecting block 211 to move toward the pipe wall, thereby driving the inspection device 112 and the metal film tube 123 to move toward the outer wall of the pipe. When it moves to the desired position, the operator's force on the handheld rod 15 toward the outer wall of the pipe will decrease and gradually disappear. At this time, the connecting rod 212 will be The action of the telescopic rod 213 causes the connecting rod 212 to move toward the center of the device. At this time, the arc plate 223 will clamp the outer wheel 222 in the contact position of the arc plate 223 under the action of the spring 224. Due to the internal structure of the outer wheel 222, the outer wheel 222 cannot pass through the contact position with the arc plate 223, which in turn inhibits the outer wheel 222 from moving toward the center of the device. At this time, due to the interaction between the friction between the outer wheel 222 and the outer wall of the pipe 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 of human factors on the inspection results; the fixing assembly 31 includes several fixing blocks 311 fixedly connected to the outer wall of the conical telescopic tube 121, and the inner walls of the several fixing blocks 311 are rotatably connected to the piston rod 312, and the outer wall of the piston rod 312 is fixedly connected to the piston plate 313.

[0066] 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 rotatably connected to the outer wall of the connecting shafts 321 , and a sleeve 323 slidably connected to the outer wall of the piston plate 313 .

[0067] When the device moves toward the outer wall of the pipe, it will drive the auxiliary mechanism 3 to contact the outer wall of the pipe. After the outer wall of the sleeve 323 contacts the outer wall of the pipe, when the device continues to move, the piston rod 312 will drive the piston plate 313 to move toward the outer wall of the pipe. At this time, the 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 pipe, so that the one-way plates 322 will be squeezed due to the air, causing the air to overflow from the one-way plates 322. Since coupling agent is sprayed on the outer wall of the pipe when testing the pipe pressure, when the sleeve 323 contacts the outer wall of the pipe, the coupling agent will seal the contact position between the sleeve 323 and the outer wall of the pipe, thereby making it difficult for the piston rod 312 to drive the piston plate 313 to move away from the outer wall of the pipe after the air between the sleeve 323 and the piston plate 313 escapes, thereby strengthening the connection between the probe device and the outer wall of the pipe and reducing the influence of the vibration of the pipe during use on the probe.

[0068] A specific application of this embodiment is as follows: when in use, a worker holds the hand-held rod 15 and moves the probe device toward the outer wall of the pipe to be inspected. When the outer wall of the tapered telescopic tube 121 contacts the outer wall of the pipe to be inspected, the tapered telescopic tube 121 will begin to contract toward the hand-held rod 15, so that the air in the space between the tapered telescopic tube 121 and the inner wall of the inspection device 112 is squeezed outward, and the squeezed air will blow the surface attachments at the contact point between the metal film tube 123 and the pipe wall. The blown attachments will escape from the cleaning channel 122 with the flow of air, thereby maintaining the cleanliness of the contact point between the metal film tube 123 and the pipe wall and improving the accuracy of the inspection result. When the handheld rod 15 moves toward the outer wall of the pipe, the outer wheel 222 will contact the outer wall of the pipe, 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 connected to it to move away from the center of the device, and the connection 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 telescopic rod 213 and the rotation connection between the connecting rod 212, causing the telescopic rod 213 to extend out of the tapered telescopic tube 121. Further, the rotation of the connecting rod 212 will cause the connecting block 211 to move toward the pipe wall, thereby driving the inspection device 112 and the metal The membrane tube 123 moves toward the outer wall of the pipe. When it moves to the desired position, the operator's force on the hand-held rod 15 toward the outer wall of the pipe will decrease and gradually disappear. At this time, the connecting rod 212 will move toward the center of the device due to the action of the telescopic rod 213. At this time, the arc plate 223 will clamp the outer wheel 222 at the contact position of the arc plate 223 under the action of the spring 224. Due to the internal structure of the outer wheel 222, the outer wheel 222 cannot pass through the contact position with the arc plate 223, thereby inhibiting the outer wheel 222 from moving toward the center of the device. At this time, due to the friction between the outer wheel 222 and the outer wall of the pipe and the telescopic rod 213, the outer wheel 222 is prevented from moving toward the center of the device. The pulling force of the rod 213 on the connecting rod 212 interacts with each other, making it difficult for the device to change the angle between it and the pipe wall, thereby reducing the impact of human factors on the inspection; as the device gradually moves toward the pipe wall, the metal film tube 123 will gradually approach the outer wall of the pipe. When the outer wall of the metal film tube 123 contacts the outer wall of the pipe, the sliding connection between the lever 3 115 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 pipe is different, the positions of the multiple levers 3 115 slidingly connected on the inner wall are different. Therefore, the metal film tube 123 will be tightly attached to the outer wall of the pipe under the action of the lever 3 115.Since the fixing plates 116 are a group of two, they are rotated to connect the outer wall of the lever three 115 and are close to the outer wall of the metal film tube 123. The fixing plates 116 are rotated to connect the outer wall of the lever two 114 and are close to the connection between the lever two 114 and the lever three 115. The fixing plates 116 are rotated to connect the outer wall of the lever one 113 and are close to the connection between the lever one 113 and the lever two 114. As a result, the metal film tube 123 transmits the echo to the lever three 115 when receiving the echo. Since the position of the lever three 115 is close to the metal film tube 123, the fixing plates 116 are rotated to connect the outer wall of the lever two 114 and are close to the connection between the lever one 113 and the lever two 114. The force arm between the plate 116 and the metal film tube 123 is smaller than the force arm between the lever 2 114 and the lever 3 115 connected to the fixed plate 116, so that the vibration received by the connection between the lever 2 114 and the lever 3 115 will be greater than the vibration received by the connection between the lever 3 115 and the metal film tube 123. Similarly, the vibration received by the connection between the lever 1 113 and the lever 2 114 will be greater than the vibration received by the connection between the lever 2 114 and the lever 3 115, and the vibration received by the connection between the lever 1 113 and the inspection device 112 will be greater than the vibration received by the connection between the lever 1 113 and the lever 3 The connection between the two 114, ultimately, makes the echo vibration received by the inspection device 112 be amplified, which is conducive to improving the accuracy of the inspection result; when the device moves toward the outer wall of the pipeline, it will drive the auxiliary mechanism 3 to 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 drives the piston plate 313 to move toward the outer wall of the pipeline. At this time, the several one-way plates 322 set 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, thereby making Air squeezes the one-way plate 322, causing it to escape. When testing the pipeline pressure, coupling agent is sprayed onto the pipeline's outer wall. When the sleeve 323 contacts the pipeline's outer wall, the coupling agent seals the contact between the sleeve 323 and the piston plate 313. This prevents the piston rod 312 from moving the piston plate 313 away from the pipeline's outer wall after the air between the sleeve 323 and the piston plate 313 escapes. This strengthens the connection between the probe assembly and the pipeline's outer wall and reduces the impact of pipeline vibration on the probe during use.
