The output end of the motor rotates through the base plate and is fixedly sleeved with a gear and a first pulley. A first toothed plate and a second toothed plate are respectively provided on the outer side of the gear. The rotation of the motor drives the gear, and the first toothed plate and the second toothed plate meshing with the gear push the connecting rod and the connected first clamping plate to move towards the bottom of the pipe.

Description

Technical Field

[0001] This utility model relates to the field of leakage detection technology, and in particular to an auxiliary positioning device for leakage detection. Background Technology

[0002] In industrial production and urban infrastructure construction, pipeline systems are widely used to transport various fluids, such as oil, natural gas, and water. The safe and stable operation of pipelines is of paramount importance. Once a leak occurs, it will not only cause waste of resources, but may also lead to serious consequences such as environmental pollution and safety accidents. Therefore, accurately and efficiently detecting the location of pipeline leaks has become a key link in ensuring the normal operation of pipeline systems.

[0003] Traditional pipeline leak detection methods often only allow for fixing the pipeline from one side or a limited number of directions, failing to provide uniform and stable clamping around the pipeline's perimeter. Under complex operating conditions, the detection equipment is prone to displacement due to pipeline vibration or other factors, affecting the accuracy and reliability of the detection. Therefore, an auxiliary positioning device for leak detection is proposed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary positioning device for leakage detection, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary positioning device for leakage detection includes a base plate. A motor is fixedly installed on the bottom side of the base plate. The output end of the motor rotates through the base plate and is respectively fixedly sleeved with a gear and a first pulley. A first toothed plate and a second toothed plate are respectively provided on the outer side of the gear. Both the first toothed plate and the second toothed plate mesh with the gear. A bottom clamping assembly is provided on the top side of both the first toothed plate and the second toothed plate. A fixing frame is fixedly installed on one side of the base plate. A mounting frame is fixedly installed on the top side of the fixing frame. A top clamping assembly is provided inside the mounting frame. A linkage assembly is provided between the fixing frame and the first pulley. A fixing plate is fixedly installed on the top side of the base plate. A detection assembly is provided on one side of the fixing plate.

[0006] Preferably, the bottom clamping assembly includes a bottom plate with two sliding holes on the top side, and a connecting rod is slidably installed in each of the two sliding holes. The two connecting rods are both L-shaped and symmetrically arranged. The ends of the two connecting rods that are close to each other are fixedly connected to a first clamping plate. The bottom ends of the two connecting rods are fixedly connected to the top sides of the first toothed plate and the second toothed plate, respectively.

[0007] Preferably, the top clamping assembly includes a circular hole on one side of the mounting frame, a bidirectional screw is provided in the circular hole, one end of the bidirectional screw is rotatably connected to the inner wall of one side of the mounting frame, two sliders are threaded onto the outer side of the bidirectional screw, and a connecting plate is fixedly installed on the bottom side of each slider. The two connecting plates are both L-shaped and symmetrically arranged. A second clamping plate is fixedly connected to the side of the two connecting plates that are close to each other, and the two second clamping plates are located above the two first clamping plates.

[0008] Preferably, the mounting bracket has an elongated hole on its top side, and two guide blocks are slidably installed in the elongated hole. The bottom sides of the two guide blocks are respectively fixedly connected to the top sides of the two sliders.

[0009] Preferably, the linkage assembly includes a circular hole on the top side of the fixed frame, a linkage rod inside the circular hole, the bottom end of the linkage rod being rotatably connected to the inner wall of the bottom side of the fixed frame, and a second pulley being fixedly sleeved on the outer side of the linkage rod, the second pulley and the first pulley sharing the same belt.

[0010] Preferably, a first bevel gear and a second bevel gear are fixedly connected to the top end of the linkage rod and the other end of the bidirectional screw, respectively, and the first bevel gear and the second bevel gear mesh with each other.

[0011] Preferably, the detection assembly includes an electric push rod fixedly installed on one side of a fixed plate, the output end of the electric push rod passing through the fixed plate and fixedly connected to an ultrasonic detector, a side plate fixedly installed on one side of the fixed plate, and a controller provided on the top side of the side plate. The controller is electrically connected to the motor, the electric push rod and the ultrasonic detector respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The motor drives the gears, and the first and second gear plates meshing with the gears push the connecting rod and the connected first clamping plate to move towards the bottom of the pipe. At the same time, the first pulley at the output end of the motor drives the linkage rod in the second pulley to rotate via the belt. Then, through the meshing of the first and second bevel gears, the bidirectional screw rotates, driving the slider and the second clamping plate to move towards the top of the pipe. Compared with the traditional single-sided or limited-direction fixing, this device uses multiple clamping plates to clamp synchronously from the top and bottom sides, ensuring uniform force on the outer circumference of the pipe, greatly improving stability, effectively avoiding the displacement of the detection equipment due to pipe vibration and displacement, and significantly improving the accuracy and reliability of positioning and clamping.

[0013] 2. Through the coordinated operation of two first clamps and two second clamps, the pipeline is firmly fixed throughout the leakage detection process. When the ultrasonic detector is working, the pipeline remains stable and does not shake, ensuring that the collected ultrasonic reflection wave data is stable and reliable. Furthermore, the stable pipeline state allows the time, amplitude, and other characteristics of the reflected waves to accurately reflect the leakage situation, avoiding data deviation caused by shaking interference. At the same time, the fixing plate fixes the electric push rod, ensuring that the detector is stably inserted into the pipeline. Compared with traditional methods, this device greatly enhances the detection stability and ensures accurate detection results. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1-4An auxiliary positioning device for leakage detection includes a base plate 1. A motor 2 is fixedly mounted on the bottom side of the base plate 1. The output end of the motor 2 rotates through the base plate 1 and is respectively fixedly sleeved with a gear 3 and a first pulley 8. A first toothed plate 4 and a second toothed plate 5 are respectively provided on the outer side of the gear 3. Both the first toothed plate 4 and the second toothed plate 5 mesh with the gear 3. Bottom clamping components are provided on the top sides of the first toothed plate 4 and the second toothed plate 5. A fixing frame 9 is fixedly mounted on one side of the base plate 1. A mounting frame 14 is fixedly mounted on the top side of the fixing frame 9. A top clamping component is provided inside the mounting frame 14. A linkage assembly is provided between the frame 9 and the first pulley 8. A fixing plate 21 is fixedly installed on the top side of the base plate 1. A detection assembly is provided on one side of the fixing plate 21. The bottom clamping assembly includes two sliding holes on the top side of the base plate 1. A connecting rod 6 is slidably installed in each of the two sliding holes. The two connecting rods 6 are both L-shaped and symmetrically arranged. The ends of the two connecting rods 6 that are close to each other are fixedly connected to the first clamping plate 7. The bottom ends of the two connecting rods 6 are fixedly connected to the top sides of the first toothed plate 4 and the second toothed plate 5, respectively. By providing a gear 3, the first toothed plate 4 and the second toothed plate 5 are both connected to the gear 3. Under the transmission action of gear 3, the first toothed plate 4 and the second toothed plate 5 respectively drive the connecting rod 6 fixedly installed on their top sides to move closer to each other. Since the connecting rod 6 is firmly connected to the first clamping plate 7, this causes the two first clamping plates 7 to move synchronously towards the bottom of the pipe. At the same time, the operation of motor 2 also drives the linkage component to operate. The first pulley 8 at the output end of motor 2 drives the second pulley 11 through belt 12, and the linkage rod 10 rotates accordingly. Through the meshing transmission of bevel gears, the bidirectional screw 15 rotates, causing the two sliders 17 to drive the two second clamping plates 19 to move synchronously towards the bottom of the pipe. With the top of the pipe close together, the two first clamping plates 7 clamp the bottom of the pipe and the two second clamping plates 19 clamp the top of the pipe simultaneously, achieving synchronous positioning and clamping of multiple positions of the pipe. Throughout the leakage detection process, the multi-position synchronous clamping method keeps the pipe stable at all times, effectively avoiding deviations in the data collected by the ultrasonic detector 23 due to pipe shaking, which would interfere with the detection results and ensure accurate and reliable detection results. Furthermore, since both connecting rods 6 slide within their respective sliding holes, they also limit the movement of the first toothed plate 4 and the second toothed plate 5.

[0018] Specifically, the top clamping assembly includes a circular hole on one side of the mounting bracket 14, within which a bidirectional screw 15 is installed. One end of the bidirectional screw 15 is rotatably connected to the inner wall of one side of the mounting bracket 14. Two sliders 17 are threaded onto the outer side of the bidirectional screw 15. Connecting plates 18 are fixedly installed on the bottom sides of both sliders 17. The two connecting plates 18 are L-shaped and symmetrically arranged. Second clamping plates 19 are fixedly connected to the sides of the two connecting plates 18 that are close to each other. The two second clamping plates 19 are located above the two first clamping plates 7. An elongated hole is provided on the top side of the mounting bracket 14, within which two... Two guide blocks 20 are fixedly connected to the top sides of two sliders 17 respectively. The linkage assembly includes a circular hole on the top side of the fixed frame 9, in which a linkage rod 10 is installed. The bottom end of the linkage rod 10 is rotatably connected to the inner wall of the bottom side of the fixed frame 9. A second pulley 11 is fixedly sleeved on the outer side of the linkage rod 10. The second pulley 11 and the first pulley 8 share the same belt 12. The top end of the linkage rod 10 and the other end of the bidirectional screw 15 are fixedly connected to a first bevel gear 13 and a second bevel gear 16 respectively. The first bevel gear 13 and the second bevel gear 16 mesh with each other and are connected by a motor. The first pulley 8, which is fixedly sleeved at the output end of the 2, is connected to the second pulley 11 via the same belt 12. Under the transmission of the belt 12, the second pulley 11 synchronously drives the linkage rod 10 to rotate clockwise. The top of the linkage rod 10 is fixedly connected to the first bevel gear 13, which meshes with the second bevel gear 16. During this meshing transmission process, power is smoothly transmitted from the first bevel gear 13 to the second bevel gear 16, which in turn causes the second bevel gear 16 to synchronously drive the bidirectional screw 15 to rotate counterclockwise. The two sliders 17, which are threaded onto the outer side of the bidirectional screw 15, are connected to the bidirectional screw 15. The rotation of the screw, based on the principle of screw drive, will move synchronously towards each other along the screw axis, thereby synchronously driving the second clamping plate 19 on one side of the two connecting plates 18 to move towards the top of the pipe and clamp it. In this way, by clamping the bottom of the pipe with the two first clamping plates 7 and clamping the top of the pipe with the two second clamping plates 19, synchronous positioning and clamping of multiple positions of the pipe is achieved. Furthermore, guide blocks 20 are fixedly installed on the top side of the two sliders 17. The two guide blocks 20 can guide and limit the movement of the two sliders 17 when they approach or move towards each other, so that they can move smoothly.

[0019] Specifically, the detection assembly includes an electric push rod 22 fixedly installed on one side of a fixed plate 21. The output end of the electric push rod 22 passes through the fixed plate 21 and is fixedly connected to an ultrasonic detector 23. A side plate 24 is fixedly installed on one side of the fixed plate 21, and a controller 25 is set on the top side of the side plate 24. The controller 25 is electrically connected to the motor 2, the electric push rod 22, and the ultrasonic detector 23. With the ultrasonic detector 23 installed, after the pipe is firmly clamped, starting the electric push rod 22 will drive the ultrasonic detector 23 to extend into the pipe. Subsequently, the ultrasonic detector 23 can perform leakage detection. Because the ultrasonic detector 23 is electrically connected to the controller 25, it can transmit data to the controller 25 for display in a timely manner, making it easy for personnel to know the leakage situation of the pipe. Furthermore, the controller 25 is electrically connected to the motor 2 and the electric push rod 22, so the controller 25 can also control the forward and reverse rotation of the motor 2 and the extension and retraction of the electric push rod 22.

[0020] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0021] In use: Place the pipe to be tested on the base plate 1, positioning it between the two first clamping plates 7 and the two second clamping plates 19. Then start the motor 2. The output shaft of the motor 2 drives the gear 3 to rotate clockwise. Since the first toothed plate 4 and the second toothed plate 5 are both meshed with the gear 3, under the transmission action of the gear 3, the first toothed plate 4 and the second toothed plate 5 respectively drive the connecting rod 6 fixedly installed on their top sides to move closer to each other, thereby causing the two first clamping plates 7 to move synchronously towards the bottom of the pipe. At the same time, the first pulley 8 fixedly sleeved at the output end of the motor 2... The second pulley 11 is connected to the same belt 12. Under the transmission of the belt 12, the second pulley 11 synchronously drives the linkage rod 10 to rotate clockwise. The top of the linkage rod 10 is fixedly connected to the first bevel gear 13, and the first bevel gear 13 meshes with the second bevel gear 16. Therefore, under the transmission action of the first bevel gear 13, the second bevel gear 16 synchronously drives the double-acting screw 15 to rotate counterclockwise. The two sliders 17 threaded on the outer side of the double-acting screw 15 will synchronously drive the second clamping plate 19 on one side of the two connecting plates 18 to move towards the top of the pipe. The system clamps the pipe, with the two first clamping plates 7 clamping the bottom of the pipe, thus achieving synchronous positioning and clamping of multiple positions on the pipe. After the clamping operation is completed, the electric push rod 22 is started. The telescopic rod of the electric push rod 22 extends, driving the ultrasonic detector 23 to gradually extend into the inner wall of the pipe. At this time, the ultrasonic detector 23 starts working and emits ultrasonic pulses into the pipe. When the ultrasonic waves encounter changes or defects in the medium inside the pipe, reflection, refraction, and scattering phenomena will occur. By analyzing the time, amplitude, and other characteristics of the reflected waves, it is possible to determine whether there is leakage in the pipe and the specific location of the leakage. The specific data obtained from these detections will be displayed on the controller 25. During the entire leakage detection process, the use of synchronous clamping at multiple positions effectively avoids interference with the detection results caused by pipe shaking. After the detection work is completed, the motor 2 is started again, causing it to drive the gear 3 and the first pulley 8 to rotate counterclockwise synchronously. Under the reverse transmission action, the two first clamping plates 7 and the two second clamping plates 19 move away from the pipe, thereby stopping the clamping of the pipe for subsequent operations.
