Description

Technical Field

[0001] The present invention relates to the technical field of impulse turbines, and particularly to an adjustment and detection device for a water distribution ring pipe of a vertical shaft multi-nozzle impulse turbine. Background Art

[0002] A vertical shaft multi-nozzle impulse turbine is a type of turbine that uses the kinetic energy of water flow to drive the runner to rotate. It belongs to a kind of impulse turbine. Its working principle is to spray high-pressure water flow at high speed onto the runner through multiple nozzles, and use the impact force of the water flow on the runner blades to make it rotate, thereby converting water energy into mechanical energy. Compared with other impulse turbines, the vertical shaft multi-nozzle impulse turbine can operate efficiently under high head conditions, can automatically adjust the rotational speed under different loads, maintain power generation efficiency and stability, can withstand large overloads and impacts, has strong anti-sand abrasion and anti-corrosion capabilities, has lower construction costs and operating costs, and has higher economic benefits;

[0003] In the actual working process, water flows along the pipeline, and the nozzles are installed on the side wall of the pipeline. Multiple pipelines form a water distribution ring pipe. During the installation process of the vertical shaft multi-nozzle impulse turbine, first determine and install the positions of the main shaft and the blades, and then, according to the position of the main shaft and the direction of the water flow in the water inlet pipe, lay all other pipelines in sequence. When laying the pipelines, multi-parameter regulation in multiple directions and at multiple angles is required according to the elevation, center and perpendicularity of the nozzle flange, the nozzle flange spacing, the distances from the nozzle flange and the water inlet flange of the water distribution ring pipe to the center of the unit, and the misalignment of the circumferential joints between the water distribution ring pipes, as well as the reserved amount and the welding deformation amount. During the detection process of various data among them, mainly multiple straight rulers are used for measurement, and the cost is low. However, in the actual detection and adjustment process, since the nozzles and pipelines are all circular, and various data are basically detected based on the center of the pipeline, using traditional straight rulers for detection requires multiple people to cooperate with each other. It is time-consuming and laborious, and the overall detection difficulty is extremely high. Moreover, during the measurement process, only the measurement effect can be completed, and there are no other functions. Therefore, an adjustment and detection device for a water distribution ring pipe of a vertical shaft multi-nozzle impulse turbine is provided. Summary of the Invention

The distance between the center of the pipe and the control ball can be directly read through the scale line on the outer side of the threaded cylinder, which is simple and convenient. When measuring the internal data of the pipe, two sets of the device can be selected. When the control balls on the outer sides of the two threaded cylinders abut against each other, it means that the adjacent two pipes are on the same horizontal line, and then the measurement operation of the position between the centers of the adjacent pipes is completed;

[0018] 3. Then, when performing the measurement operation, a knocking effect on the pipe will be formed. After the measurement is completed, it can be observed whether there are cracks at the knocking position. If there are cracks, it means that the quality of the pipe is poor and needs to be replaced in time. If there are no problems, it can be used normally. Thus, during the detection process, a simple detection of the pipe quality can also be completed. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0032] Refer to Figures 1-12, An adjustment and detection device for the water distribution ring pipe of a vertical shaft multi-nozzle impulse water turbine, comprising a housing 1. Inside the housing 1, a limiting ring 34 is fixedly connected. A first frustum 31 is slidably connected to the outside of the limiting ring 34. The first frustum 31 is rotatably connected to a threaded ring 11. A threaded cylinder 5 is connected to the threaded ring 11 by internal threads. The threaded cylinder 5 slidably penetrates through the housing 1. A rotating ring 2 is rotatably connected inside the housing 1. A conical tooth ring 9 is fixedly connected to the side of the rotating ring 2 close to the threaded ring 11. A plurality of threaded rods 12 penetrate through the side wall of the housing 1 and are rotatably connected. A second connecting rod 18 is connected to the plurality of threaded rods 12 through a clamping component. A conical gear 25 is fixedly connected to the outside of the second connecting rod 18. Each conical gear 25 meshes with the conical tooth ring 9. A moving ring 13 is threadedly connected to the outside of each threaded rod 12. The moving ring 13 is fixedly connected to a moving plate 14. A fixed frame 7 is fixedly connected to the outside of the housing 1. The moving plate 14 slidably penetrates through the fixed frame 7. A clamping plate 6 is fixedly connected to the side wall of the moving plate 14. A first connecting rod 3 is fixedly connected to the lower side of the housing 1. A triangular support 4 is fixedly connected to the lower side of the first connecting rod 3. A rubber pad is fixedly connected to the outside of the triangular support 4. A rotating rod 8 is fixedly connected to the outside of the rotating ring 2. An anti-slip rubber sleeve is sleeved on the outside of the rotating rod 8. A deep groove is opened on the outside of the threaded cylinder 5, and a scale line is provided in the deep groove. A seventh connecting plate 41 is fixedly connected inside the threaded cylinder 5. A sixth connecting rod 42 is slidably connected to the seventh connecting plate 41. The sixth connecting rod 42 penetrates through the threaded cylinder 5. Control balls 43 are fixedly connected to both ends of the sixth connecting rod 42. A fifth connecting plate 15 is fixedly connected to the outside of the sixth connecting rod 42. A fourth spring 44 is fixedly connected between the fifth connecting plate 15 and the seventh connecting plate 41;

[0033] First, the housing 1 is cylindrical, and a circular groove is opened on one side of the housing 1. The rotating ring 2 is located in the circular groove and is rotatably connected to the circular groove. A through hole is opened at the bottom of the circular groove. The limiting ring 34 is fixed in the through hole. The threaded cylinder 5 slidably penetrates through the through hole, that is, a slider is fixedly connected to the inner wall of the through hole. A deep groove is opened on the outside of the threaded cylinder 5, and the slider and the deep groove are slidably connected. Both the upper and lower sides of the clamping plate 6 are serrated. Secondly, the triangular support 4 is a tripod in real life. The triangular support 4 is placed on the ground. By adjusting the triangular support 4, the adjustment and fixing operations of the position of the housing 1 are completed. This is prior art and will not be elaborated further.

[0034] Then, when data measurement is carried out, the whole device is placed outside the pipeline. The rotating ring 2 is driven to rotate by the rotating rod 8. The rotating ring 2 drives the second connecting rod 18 to rotate through the conical tooth ring 9 and the bevel gear 25. The second connecting rod 18 drives the threaded rod 12 to rotate through the clamping component (the structure and working principle of the clamping component are described below). Since the moving plate 14 and the fixed frame 7 are slidably connected, and the moving plate 14 and the moving ring 13 are fixedly connected, and the moving ring 13 and the threaded rod 12 are threadedly connected, the rotating threaded rod 12 will drive the moving ring 13 and the moving plate 14 to move away from the center of the housing 1. The moving plate 14 drives the clamping plate 6 to move away from the center of the housing 1 until all the clamping plates 6 abut against the inner wall of the pipeline. At this time, the center of the housing 1 and the center of the pipeline are concentric. At this time, the threaded cylinder 5 can be regarded as a straight line, that is, the threaded cylinder 5 is located at the center of the pipeline, thus completing the rapid determination operation of the pipeline center;

[0035] The clamping component includes a sliding ring 45 slidably installed in the threaded rod 12. An eighth connecting rod 19 is slidably connected in the sliding ring 45. One end of the eighth connecting rod 19 is fixedly connected to the second connecting rod 18, and the other end of the eighth connecting rod 19 is rotatably connected to the threaded rod 12. A fifth spring 48 is fixedly connected between the sliding ring 45 and the threaded rod 12. A seventh connecting rod 46 is fixedly connected to the upper side of the sliding ring 45. A plurality of fourth connecting plates 47 are slidably connected to the side wall of the fixed frame 7. The positions and numbers of the plurality of fourth connecting plates 47 correspond to those of the threaded rod 12. A sliding rod 50 is slidably connected to the side wall of the moving plate 14. One end of the sliding rod 50 is fixedly connected to a triangular plate 51, and the other end of the sliding rod 50 is fixedly connected to a sixth connecting plate 49. The fourth connecting plate 47 and the sixth connecting plate 49 are slidably connected up and down;

[0036] First, the outer side of the sliding ring 45 is circularly arranged, and the inner side of the sliding ring 45 is square. The eighth connecting rod 19 can be divided into two parts. Among them, the upper part of the eighth connecting rod 19 is also square, and the lower part of the eighth connecting rod 19 is circular. When using the device for detection operation, the inclined surface of the triangular plate 51 should face the inner wall of the pipeline end, that is, in the process of the triangular plate 51 following the clamping plate 6 to move, when the clamping plate 6 is about to abut against the inner wall of the pipeline, the inclined surface of the triangular plate 51 has already abutted against the inner wall of the pipeline end. Then, in the initial state, the sliding ring 45 is sleeved on the upper part of the eighth connecting rod 19, and the sliding ring 45 and the threaded rod 12 are slidably connected up and down. Therefore, at the beginning, the rotating second connecting rod 18 drives the eighth connecting rod 19 to rotate. The eighth connecting rod 19 drives the threaded rod 12 to rotate through the sliding ring 45. The threaded rod 12 drives the moving plate 14 and the clamping plate 6 to move through the moving ring 13. The clamping plate 6 drives the triangular plate 51 to move through the moving plate 14 and the sliding rod 50. When the clamping plate 6 abuts against the inner wall of the pipeline, the triangular plate 51 has already been squeezed by the side wall of the pipeline end, so the triangular plate 51 will move relative to the moving plate 14 to the right.Figure 4 Based on the direction of Figure 4 , the triangular plate 51 drives the sixth connecting plate 49 to move to the right through the sliding rod 50. The sixth connecting plate 49 drives the fourth connecting plate 47 to move to the right. The fourth connecting plate 47 abuts against the seventh connecting rod 46 and drives the seventh connecting rod 46 to move downward. The seventh connecting rod 46 drives the sliding ring 45 to move downward. The sliding ring 45 stretches the fifth spring 48. At this time, the sliding ring 45 moves from the upper part of the eighth connecting rod 19 to the lower part of the eighth connecting rod 19. As a result, the eighth connecting rod 19 that follows the rotation of the second connecting rod 18 does not drive the sliding ring 45 to rotate. At this time, the second connecting rod 18 and the threaded rod 12 are in a rotational connection state. It should be noted here that referring to the appendix Figure 4 , the fourth connecting plate 47 and the sixth connecting plate 49 are connected by up-and-down sliding, so it does not affect the movement of the clamping plate 6 towards the inner wall of the pipeline. And the fourth connecting plate 47 and the fixed frame 7 are connected by left-and-right sliding. At the same time, a trapezoidal notch is opened on one side of the fourth connecting plate 47. When the side wall of the trapezoidal notch of the fourth connecting plate 47 abuts against the seventh connecting rod 46, when the fourth connecting plate 47 moves to the right, it will drive the seventh connecting rod 46 to slide downward.

[0037] Such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , a measuring component is installed in the housing 1. The measuring component includes a round rod 20 fixedly installed on the lower side of the sliding ring 45. A moving cylinder 21 is slidably connected to the outer side of the second connecting rod 18. A notch 22 is opened on the side wall of the moving cylinder 21. A second frustum 23 is fixedly connected to the outer side of the moving cylinder 21. A positioning ring 24 is fixedly connected to the outer side of the second connecting rod 18. A first spring 26 is fixedly connected between the positioning ring 24 and the moving cylinder 21. A plurality of positioning plates 16 are fixedly connected in the housing 1. The second connecting rod 18 rotates through the positioning plates 16. A third connecting rod 27 is slidably penetrated through the positioning plates 16. A second connecting plate 29 is fixedly connected to the upper side of the third connecting rod 27. A second spring 28 is fixedly connected between the second connecting plate 29 and the positioning plates 16. A curved block 17 is fixedly connected to the lower side of the third connecting rod 27. The curved block 17 is located inside the first frustum 31 and abuts against the first frustum 31. A plurality of third connecting plates 30 are fixedly connected to the outer circumference of the threaded ring 11 in a circumferentially uniform manner. A plurality of first connecting plates 10 are fixedly connected to the side wall of the rotating ring 2 in a circumferentially uniform manner. A plurality of third springs 33 are fixedly connected between the first frustum 31 and the housing 1. The outer surfaces of the second frustum 23 and the first frustum 31 are both smooth, that is, the frictional forces on the outer surfaces of the second frustum 23 and the first frustum 31 are small and can be ignored;

[0038] As can be seen from the above description, after the clamping plate 6 abuts against the inner wall of the pipeline, the second connecting rod 18 and the threaded rod 12 are in a rotatable connection state. The slip ring 45 drives the round rod 20 to move downward. The round rod 20 can abut against the moving cylinder 21 and drive the moving cylinder 21 to move downward. During this process, when the round rod 20 abuts against the side wall of the moving cylinder 21, an extrusion effect on the moving cylinder 21 will be formed, causing the moving cylinder 21 to move downward relative to the second connecting rod 18. Based on the Figure 6 direction, at this time, the moving cylinder 21 drives the second frustum 23 to move downward. The moving cylinder 21 compresses the first spring 26. The second frustum 23 abuts against the second connecting plate 29 and drives the second connecting plate 29 to move downward. While the second connecting plate 29 compresses the second spring 28, it drives the arc-shaped block 17 to move downward through the third connecting rod 27. When the arc-shaped block 17 abuts against the first frustum 31, the first frustum 31 will move away from the housing 1. The first frustum 31 stretches the third spring 33, and the first frustum 31 drives the threaded ring 11 to move away from the housing 1. The threaded ring 11 drives the third connecting plate 30 to move until the third connecting plate 30 moves between the first connecting plates 10. At this time, the first connecting plate 10 following the rotation ring 2 drives the third connecting plate 30 to move, and the third connecting plate 30 drives the threaded ring 11 to rotate. Since the threaded cylinder 5 is slidably connected to the housing 1, the rotating threaded ring 11 will drive the threaded cylinder 5 to move relative to the housing 1 until the control ball 43 on the outer side of the threaded cylinder 5 abuts against the object to be measured and the control ball 43 abuts against the end face of the threaded cylinder 5. Finally, the corresponding data measurement operation is completed. During this process, the center of the pipeline can be determined simply by rotating the rotating rod 8, and the measurement operation of the distance between the center of the circle and the object to be measured is simple, the measurement result is accurate, and other data measurement operations can also be completed. For example, as Figure 12 shown, select two such devices to determine the position between adjacent pipelines. If the control balls 43 on the outer sides of the two threaded cylinders 5 abut against each other, it means that the centers of the circles of the adjacent two pipelines are on the same horizontal line. And during the above measurement process, when the control ball 43 abuts against the object to be measured, continue to rotate the rotation ring 2 until the control ball 43 abutting against the object to be measured abuts against the threaded cylinder 5. During the measurement, the position of the control ball 43 relative to the threaded cylinder 5 can be observed, and then the connection situation between the other control ball 43 and the threaded cylinder 5 can be obtained. Stop rotating the rotating rod 8, and the distance between the center of the pipeline and the control ball 43 can be directly read through the scale line on the outer side of the threaded cylinder 5, which is simple and convenient.

[0039] Such as Figure 9 、 Figure 10, a knocking component is installed on the outer side of the housing 1. The knocking component includes a plurality of fourth connecting rods 32 fixedly installed inside the first frustum 31. The plurality of fourth connecting rods 32 slidably penetrate through the housing 1. The plurality of fourth connecting rods 32 are commonly fixedly connected to a control ring 35. A plurality of telescopic rods 36 are fixedly connected to the outer side of the control ring 35. The positions and quantities of the plurality of telescopic rods 36 correspond to those of the clamping plates 6. A sliding plate 38 is fixedly connected to the outer side of each telescopic rod 36. The sliding plate 38 is slidably connected to the moving plate 14. A fifth connecting rod 39 is fixedly connected to the outer side of the sliding plate 38. The outer side of the fifth connecting rod 39 is slidably connected to a sleeve 40. A knocking plate 37 is fixedly connected to the outer side of the sleeve 40. A sixth spring is fixedly connected between the fifth connecting rod 39 and the sleeve 40;

[0040] First of all, the knocking plate 37 is located outside the clamping plate 6. When the clamping plate 6 abuts against the inner wall of the pipeline, the knocking plate 37 abuts against the outer wall of the pipeline. This outer wall refers to the end perpendicular to the inner wall of the pipeline, not just the outer surface of the pipeline. Secondly, during the movement of the threaded cylinder 5, at this time, the round rod 20 is located above the moving cylinder 21. However, during this process, when the round rod 20 passes through the notch 22, the moving cylinder 21 will move upward relative to the second connecting rod 18 under the action of the first spring 26. Under the action of the second spring 28 and the third spring 33, the second connecting plate 29 as a whole and the threaded ring 11 will briefly return to their original positions relative to the housing 1. However, at this time, the rotating rod 8 and the rotating ring 2 as a whole are still in the stage of continuous rotation. Since the round rod 20 does not move, and the moving cylinder 21 rotates following the second connecting rod 18, when the round rod 20 moves out of the notch 22 again, it will continue to squeeze the moving cylinder 21. Therefore, the above process will be repeated, causing the threaded cylinder 5 to continue to move. So, the threaded ring 11 as a whole will move left and right relative to the housing 1 once. The moving threaded ring 11 as a whole drives the first frustum 31 to move. The first frustum 31 drives the sliding plate 38 to slide left and right relative to the moving plate 14 through the control ring 35 and the telescopic rods 36. The sliding plate 38 drives the knocking plate 37 to slide left and right once through the fifth connecting rod 39 and the sixth spring. The knocking plate 37 abuts against the outer wall of the pipeline, thereby forming a knocking effect on the pipeline. After the measurement is completed, it can be observed whether there are cracks at the knocking position. If there are cracks, it means that the quality of the pipeline is poor and needs to be replaced in time. If there are no problems, it can be used normally. Thus, during the detection process, a simple detection effect on the quality of the pipeline can also be completed.

[0041] In the present invention, the whole device is placed outside the pipeline. The rotating ring 2 is driven to rotate by the rotating rod 8. The rotating ring 2 drives the second connecting rod 18 to rotate through the conical tooth ring 9 and the bevel gear 25. The second connecting rod 18 drives the threaded rod 12 to rotate through the clamping component (the structure and working principle of the clamping component are described below). Since the moving plate 14 and the fixed frame 7 are slidably connected, and the moving plate 14 and the moving ring 13 are fixedly connected, and the moving ring 13 and the threaded rod 12 are threadedly connected, the rotating threaded rod 12 will drive the moving ring 13 and the moving plate 14 to move away from the center of the housing 1. The moving plate 14 drives the clamping plate 6 to move away from the center of the housing 1 until all the clamping plates 6 abut against the inner wall of the pipeline. At this time, the center of the housing 1 and the center of the pipeline are concentric. At this time, the threaded cylinder 5 can be regarded as a straight line, that is, the threaded cylinder 5 is located at the center of the pipeline, thereby completing the rapid determination operation of the center of the pipeline;

[0042] When using the device for detection operation, the inclined surface of the triangular plate 51 should face the inner wall of the pipeline end. That is, during the process of the triangular plate 51 following the clamping plate 6 moving, when the clamping plate 6 is about to abut against the inner wall of the pipeline, the inclined surface of the triangular plate 51 has already abutted against the inner wall of the pipeline end. Then, in the initial state, the sliding ring 45 is sleeved on the upper part of the eighth connecting rod 19, and the sliding ring 45 and the threaded rod 12 are slidably connected up and down. Therefore, at the beginning, the rotating second connecting rod 18 drives the eighth connecting rod 19 to rotate. The eighth connecting rod 19 drives the threaded rod 12 to rotate through the sliding ring 45. The threaded rod 12 drives the moving plate 14 and the clamping plate 6 to move through the moving ring 13. The clamping plate 6 drives the triangular plate 51 to move through the moving plate 14 and the sliding rod 50. When the clamping plate 6 abuts against the inner wall of the pipeline, the triangular plate 51 has already been squeezed by the side wall of the pipeline end. Therefore, the triangular plate 51 will move to the right relative to the moving plate 14. Based on the Figure 4 direction, the triangular plate 51 drives the sixth connecting plate 49 to move to the right through the sliding rod 50. The sixth connecting plate 49 drives the fourth connecting plate 47 to move to the right. The fourth connecting plate 47 abuts against the seventh connecting rod 46 and drives the seventh connecting rod 46 to move downward. The seventh connecting rod 46 drives the sliding ring 45 to move downward. The sliding ring 45 stretches the fifth spring 48. At this time, the sliding ring 45 moves from the upper part of the eighth connecting rod 19 to the lower part of the eighth connecting rod 19. As a result, the eighth connecting rod 19 that rotates following the second connecting rod 18 will not drive the sliding ring 45 to rotate. At this time, the second connecting rod 18 and the threaded rod 12 are in a rotating connection state. It should be noted here that referring to the attached Figure 4, the fourth connecting plate 47 and the sixth connecting plate 49 are connected in a vertically sliding manner, so it does not affect the movement of the clamping plate 6 towards the inner wall of the pipeline. Moreover, the fourth connecting plate 47 and the fixed frame 7 are connected in a horizontally sliding manner. At the same time, a trapezoidal notch is formed on one side of the fourth connecting plate 47. When the side wall of the trapezoidal notch of the fourth connecting plate 47 abuts against the seventh connecting rod 46, when the fourth connecting plate 47 moves to the right, it will drive the seventh connecting rod 46 to slide downwards;

[0043] After the clamping plate 6 abuts against the inner wall of the pipeline, the second connecting rod 18 and the threaded rod 12 are in a rotational connection state. The sliding ring 45 drives the round rod 20 to move downwards. The round rod 20 can abut against the moving cylinder 21 and drive the moving cylinder 21 to move downwards. During this process, when the round rod 20 abuts against the side wall of the moving cylinder 21, it will form a squeezing effect on the moving cylinder 21, causing the moving cylinder 21 to move downwards relative to the second connecting rod 18. Based on the Figure 6 direction, at this time, the moving cylinder 21 drives the second frustum 23 to move downwards. The moving cylinder 21 compresses the first spring 26. The second frustum 23 abuts against the second connecting plate 29 and drives the second connecting plate 29 to move downwards. While the second connecting plate 29 compresses the second spring 28, it drives the arc-shaped block 17 to move downwards through the third connecting rod 27. When the arc-shaped block 17 abuts against the first frustum 31, it will cause the first frustum 31 to move away from the housing 1. The first frustum 31 stretches the third spring 33, and the first frustum 31 drives the threaded ring 11 to move away from the housing 1. The threaded ring 11 drives the third connecting plate 30 to move until the third connecting plate 30 moves between the first connecting plates 10. At this time, the first connecting plate 10 following the rotation ring 2 drives the third connecting plate 30 to move, and the third connecting plate 30 drives the threaded ring 11 to rotate. Since the threaded cylinder 5 is slidably connected to the housing 1, the rotating threaded ring 11 will drive the threaded cylinder 5 to move relative to the housing 1 until the control ball 43 on the outer side of the threaded cylinder 5 abuts against the measured object and the control ball 43 abuts against the end face of the threaded cylinder 5. Finally, the corresponding data measurement operation is completed. During this process, the determination of the center of the pipeline and the measurement of the distance between the center and the measured object can be completed simply by rotating the rotating rod 8. The operation is simple, the measurement result is accurate, and other data measurement operations can also be completed. For example, Figure 12As shown, two of these devices are selected to determine the positions between adjacent pipes. When the control balls 43 outside the two threaded cylinders 5 are in contact with each other, it means that the centers of the adjacent two pipes are on the same horizontal line. And during the above measurement process, when the control ball 43 is in contact with the object to be measured, continue to rotate the rotating ring 2 until the control ball 43 in contact with the object to be measured is in contact with the threaded cylinder 5. During the measurement, the position of the control ball 43 relative to the threaded cylinder 5 can be observed, and then the connection situation between the other control ball 43 and the threaded cylinder 5 can be obtained. Stop rotating the rod 8, and the distance between the pipe center and the control ball 43 can be directly read through the scale line on the outside of the threaded cylinder 5, which is simple and convenient.

[0044] During the movement of the threaded cylinder 5, at this time, the round rod 20 is located above the moving cylinder 21. However, during this process, when the round rod 20 passes through the notch 22, the moving cylinder 21 will move upward relative to the second connecting rod 18 under the action of the first spring 26. Under the action of the second spring 28 and the third spring 33, the second connecting plate 29 as a whole and the threaded ring 11 will briefly return to their original positions relative to the housing 1. But at this time, the rod 8 and the rotating ring 2 as a whole are still in the stage of continuous rotation. Since the round rod 20 does not move and the moving cylinder 21 rotates with the second connecting rod 18, when the round rod 20 moves out of the notch 22 again, it will continue to squeeze the moving cylinder 21. Therefore, the above process will be repeated, causing the threaded cylinder 5 to continue to move. So, the threaded ring 11 as a whole will move left and right relative to the housing 1 once. The moving threaded ring 11 as a whole drives the first frustum 31 to move. The first frustum 31 drives the slide plate 38 to slide left and right relative to the moving plate 14 through the control ring 35 and the telescopic rod 36. The slide plate 38 drives the knocking plate 37 to slide left and right once through the fifth connecting rod 39 and the sixth spring. The knocking plate 37 is in contact with the outer wall of the pipe, thereby forming a knocking effect on the pipe. After the measurement is completed, it can be observed whether there are cracks at the knocking position. If there are cracks, it means that the quality of the pipe is poor and needs to be replaced in time. If there are no problems, it can be used normally. Thus, during the detection process, a simple detection effect on the pipe quality can also be completed.
