Description

Technical Field

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

[0002] The vertical-axis multi-nozzle impulse turbine is a type of impulse turbine that uses the kinetic energy of water to drive the runner to rotate. Its working principle is to spray high-pressure water 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-axis multi-nozzle impulse turbine can operate efficiently under high head conditions, can automatically adjust the speed under different loads, maintain power generation efficiency and stability, can withstand large overloads and impacts, has strong resistance to sand abrasion and corrosion, has low construction and operating costs, and has high economic benefits. In the actual working process, water flows along the pipeline, the nozzle is installed on the side wall of the pipeline, and multiple pipelines form a water distribution ring pipe. In the installation process of the vertical axis multi-nozzle impulse turbine, the position of the main shaft and the blades is first determined and installed, and then all other pipelines are laid in sequence according to the position of the main shaft and the direction of the water flow in the water inlet pipe. When laying the pipeline, it is necessary to adjust in multiple directions and angles according to multiple parameters such as the elevation, center and verticality of the nozzle flange, the nozzle flange spacing, the distance from the nozzle flange and the water distribution ring pipe inlet flange to the center of the unit, and the annular gap between the water distribution ring pipes, as well as the reserved amount and welding deformation. In the process of detecting various data, multiple rulers are mainly used for measurement, which is low in cost. However, in the actual detection and adjustment process, since the nozzle and the pipeline are both circular, and various data are basically detected based on the center of the pipeline, the use of traditional rulers for detection requires multiple people to cooperate with each other, which is time-consuming and labor-intensive. The overall detection is extremely difficult, and in the measurement process, only the measurement effect can be completed without other functions. Therefore, an adjustment and detection device for the water distribution ring pipe of a vertical axis multi-nozzle impulse turbine is provided. Summary of the invention

Secondly, the tripod 4 is a tripod in real life. The tripod 4 is placed on the ground. By adjusting the tripod 4, the adjustment and fixing operation of the position of the shell 1 are completed. This is a prior art and no unnecessary elaboration is made. Then, when measuring data, the device is placed on the outside of the pipeline as a whole, and 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 gear ring 9 and the conical gear 25. The second connecting rod 18 drives the threaded rod 12 to rotate through the clamping assembly (the structure and working principle of the clamping assembly are shown 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 shell 1, and the moving plate 14 drives the clamping plate 6 to move away from the center of the shell 1 until all the clamping plates 6 and the inner wall of the pipeline are against each other. At this time, the center of the shell 1 and the center of the pipeline are in a concentric state. At this time, the threaded barrel 5 can be regarded as a straight line, that is, the threaded barrel 5 is located at the center of the pipeline, thereby completing the rapid determination of the center of the pipeline. The clamping assembly includes a slip ring 45 slidably installed in the threaded rod 12, an eighth connecting rod 19 is slidably connected in the slip ring 45, one end of the eighth connecting rod 19 is fixedly connected to the second connecting rod 18, 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 slip ring 45 and the threaded rod 12, a seventh connecting rod 46 is fixedly connected to the upper side of the slip ring 45, a plurality of fourth connecting plates 47 are slidably connected to the side wall of the fixed frame 7, the positions and quantities of the plurality of fourth connecting plates 47 correspond to the threaded rod 12, a sliding rod 50 is slidably connected to the side wall of the movable plate 14, one end of the sliding rod 50 is fixedly connected to a triangular plate 51, the other end of the sliding rod 50 is fixedly connected to a sixth connecting plate 49, and the fourth connecting plate 47 is slidably connected to the sixth connecting plate 49 up and down; First, the outer side of the slip ring 45 is circular, and the inner side of the slip ring 45 is square. The eighth connecting rod 19 can be divided into two parts, wherein 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 the device is used for detection operation, the inclined surface of the triangular plate 51 should be opposite to the inner wall of the pipe end, that is, when the triangular plate 51 moves with the clamping plate 6, when the clamping plate 6 is about to abut against the inner wall of the pipe, the inclined surface of the triangular plate 51 has already abutted against the inner wall of the pipe end. Then, in the initial state, the slip ring 45 is sleeved on the eighth connecting rod. 19, and the slip ring 45 and the threaded rod 12 are connected by sliding up and down, so 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 slip ring 45, the threaded rod 12 drives the moving plate 14 and the clamping plate 6 to move through the moving ring 13, and 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 and the inner wall of the pipe are against each other, the triangular plate 51 has been squeezed by the side wall of the end of the pipe, so that the triangular plate 51 will move to the right relative to the moving plate 14, so as to prevent the triangular plate 51 from moving to the right. Figure 4Based on the direction, the triangular plate 51 drives the sixth connecting plate 49 to move rightward through the sliding rod 50, the sixth connecting plate 49 drives the fourth connecting plate 47 to move rightward, the fourth connecting plate 47 and the seventh connecting rod 46 abut against each other and drive the seventh connecting rod 46 to move downward, the seventh connecting rod 46 drives the slip ring 45 to move downward, and the slip ring 45 stretches the fifth spring 48. At this time, the slip ring 45 moves from the upper part of the eighth connecting rod 19 to the lower part of the eighth connecting rod 19, thereby causing the eighth connecting rod 19 that rotates with the second connecting rod 18 to not drive the slip ring 45 to rotate. At this time, the second connecting rod 18 and the threaded rod 12 are in a rotationally connected state. It should be noted here that, with reference to the attached Figure 4 The fourth connecting plate 47 and the sixth connecting plate 49 are connected for vertical sliding movement, so it does not affect the movement of the clamping plate 6 toward the inner wall of the pipe, and the fourth connecting plate 47 and the fixed frame 7 are connected for horizontal sliding movement. 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.

[0017] like Figure 5 , Figure 6 , Figure 7 , Figure 8 A measuring assembly is installed in the housing 1, and the measuring assembly includes a round rod 20 fixedly installed on the lower side of the slip 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 truncated cone 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 and penetrates the positioning plate 16, the positioning plate 16 slides and penetrates a third connecting rod 27, and the upper side of the third connecting rod 27 is fixedly connected to the second connecting plate 2 9, a second spring 28 is fixedly connected between the second connecting plate 29 and the positioning plate 16, an arc block 17 is fixedly connected to the lower side of the third connecting rod 27, the arc block 17 is located on the inner side of the first truncated cone 31 and abuts against the first truncated cone 31, a plurality of third connecting plates 30 are evenly fixedly connected to the outer circumference of the threaded ring 11, a plurality of first connecting plates 10 are evenly fixedly connected to the side wall of the rotating ring 2, a plurality of third springs 33 are fixedly connected between the first truncated cone 31 and the housing 1, and the outer surfaces of the second truncated cone 23 and the first truncated cone 31 are both smoothly set, that is, the friction force on the outer surfaces of the second truncated cone 23 and the first truncated cone 31 is small and can be ignored; It can be seen from the above description that when the clamping plate 6 abuts against the inner wall of the pipe, the second connecting rod 18 and the threaded rod 12 are in a rotationally connected state, and the slip ring 45 drives the round rod 20 to move downward, and the round rod 20 can abut against the moving cylinder 21 to drive the moving cylinder 21 to move downward. In this process, the side walls of the round rod 20 and the moving cylinder 21 abut against each other, which will form an extrusion effect on the moving cylinder 21, causing the moving cylinder 21 to move downward relative to the second connecting rod 18, so as to prevent the moving cylinder 21 from moving downward. Figure 6 , at this time, the moving cylinder 21 drives the second truncated cone 23 to move downward, the moving cylinder 21 compresses the first spring 26, the second truncated cone 23 and the second connecting plate 29 abut against each other and drive the second connecting plate 29 to move downward, while the second connecting plate 29 compresses the second spring 28, the arc block 17 is driven downward by the third connecting rod 27, the arc block 17 and the first truncated cone 31 abut against each other, and the first truncated cone 31 is moved away from the housing 1, the first truncated cone 31 stretches the third spring 33, and the first truncated cone 31 drives the threaded ring 11 to move away from the housing 1, and 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 that moves with the rotating 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 barrel 5 and the housing 1 are slidably connected, the rotating threaded ring 11 will drive the threaded barrel 5 to move relative to the housing 1 until the control ball 43 on the outside of the threaded barrel 5 abuts against the object to be measured, and the control ball 43 abuts against the end face of the threaded barrel 5, and finally completes the measurement operation of the corresponding data. In this process, the center of the pipeline can be determined and the distance between the center of the pipeline and the object to be measured can be measured only 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, Fig.12 As shown, two devices are selected to determine the position between adjacent pipes. If the control balls 43 on the outer sides of the two threaded barrels 5 are against each other, it means that the centers of the two adjacent pipes are on the same horizontal line. In the above-mentioned measurement process, when the control ball 43 and the object to be measured are against each other, the rotating ring 2 is continuously rotated until the control ball 43 and the threaded barrel 5 that are against the object to be measured are against each other. During the measurement, the position of the control ball 43 relative to the threaded barrel 5 can be observed, and then the connection between the control ball 43 at the other end and the threaded barrel 5 can be obtained. When the rotating rod 8 is stopped, the distance between the center of the pipe and the control ball 43 can be directly read through the scale line on the outer side of the threaded barrel 5. It is simple and convenient.

[0018] like Fig. 9 , Fig.10A striking assembly is installed on the outer side of the shell 1, and the striking assembly includes a plurality of fourth connecting rods 32 fixedly installed on the inner side of the first truncated cone 31, and the plurality of fourth connecting rods 32 slide through the shell 1, and the plurality of fourth connecting rods 32 are commonly fixedly connected to a control ring 35, and a plurality of telescopic rods 36 are fixedly connected to the outer side of the control ring 35, and the positions and quantities of the plurality of telescopic rods 36 correspond to the clamping plate 6, and a slide plate 38 is fixedly connected to the outer side of each telescopic rod 36, and the slide plate 38 is slidably connected to the movable plate 14, and a fifth connecting rod 39 is fixedly connected to the outer side of the slide plate 38, and a sleeve 40 is slidably connected to the outer side of the fifth connecting rod 39, and a striking plate 37 is fixedly connected to the outer side of the sleeve 40, and a sixth spring is fixedly connected between the fifth connecting rod 39 and the sleeve 40; First, the knocking plate 37 is located on the outside of the splint 6. When the splint 6 and the inner wall of the pipe are against each other, the knocking plate 37 and the outer wall of the pipe are against each other. The outer wall refers to the end perpendicular to the inner wall of the pipe, not just the outer surface of the pipe. Secondly, during the movement of the threaded cylinder 5, the round rod 20 is located on the upper side of 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 outer shell 1. However, at this time, the rotating rod 8 and the rotating ring 2 as a whole are still in the stage of continuing to rotate. Since the round rod 20 is stationary 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 The moving cylinder 21 is squeezed, and the above process is repeated, so that the threaded cylinder 5 will continue to move, so that the threaded ring 11 as a whole will move back and forth once relative to the outer shell 1, and the threaded ring 11 that moves back and forth as a whole drives the first truncated cone 31 to move, and the first truncated cone 31 drives the slide plate 38 to slide left and right once relative to the moving plate 14 through the control ring 35 and the telescopic rod 36, and 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, and the knocking plate 37 and the outer wall of the pipe are against each other, 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 cracks appear, it means that the quality of the pipe is poor and needs to be replaced in time. If there is no problem, it can be used normally, and then during the detection process, a simple detection effect of the pipe quality can also be completed.

[0019] In the present invention, the device is placed as a whole on the outside of the pipeline, and 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 gear ring 9 and the conical gear 25. The second connecting rod 18 drives the threaded rod 12 to rotate through the clamping assembly (the structure and working principle of the clamping assembly are shown below). Since the movable plate 14 and the fixed frame 7 are slidably connected, and the movable plate 14 and the movable ring 13 are fixedly connected, and the movable ring 13 and the threaded rod 12 are threadedly connected, the rotating threaded rod 12 will drive the movable ring 13 and the movable plate 14 to move away from the center of the outer shell 1, and the movable plate 14 drives the clamping plate 6 to move away from the center of the outer shell 1 until all the clamping plates 6 and the inner wall of the pipeline are against each other. At this time, the center of the outer shell 1 and the center of the pipeline are in a concentric state. At this time, the threaded barrel 5 can be regarded as a straight line, that is, the threaded barrel 5 is located at the center of the pipeline, thereby completing the rapid determination of the center of the pipeline. When using the device for detection operation, the inclined surface of the triangular plate 51 should be opposite to the inner wall of the pipe end, that is, in the process of the triangular plate 51 following the movement of the clamping plate 6, when the clamping plate 6 is about to abut against the inner wall of the pipe, the inclined surface of the triangular plate 51 has abutted against the inner wall of the pipe end, and then, in the initial state, the slip ring 45 is sleeved on the upper part of the eighth connecting rod 19, and the slip ring 45 and the threaded rod 12 are connected by sliding up and down. Therefore, at the beginning, the rotating second connecting rod 18 drives the eighth connecting rod 19 to rotate, and the eighth connecting rod 19 drives the threaded rod 12 to rotate through the slip 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 pipe, the triangular plate 51 has been squeezed by the side wall of the pipe end, so it will cause the triangular plate 51 to move to the right relative to the moving plate 14. Figure 4 Based on the direction, the triangular plate 51 drives the sixth connecting plate 49 to move rightward through the sliding rod 50, the sixth connecting plate 49 drives the fourth connecting plate 47 to move rightward, the fourth connecting plate 47 and the seventh connecting rod 46 abut against each other and drive the seventh connecting rod 46 to move downward, the seventh connecting rod 46 drives the slip ring 45 to move downward, and the slip ring 45 stretches the fifth spring 48. At this time, the slip ring 45 moves from the upper part of the eighth connecting rod 19 to the lower part of the eighth connecting rod 19, thereby causing the eighth connecting rod 19 that rotates with the second connecting rod 18 to not drive the slip ring 45 to rotate. At this time, the second connecting rod 18 and the threaded rod 12 are in a rotationally connected state. It should be noted here that, with reference to the attached Figure 4The fourth connecting plate 47 and the sixth connecting plate 49 are connected by sliding up and down, so that the clamping plate 6 does not move toward the inner wall of the pipe, and the fourth connecting plate 47 and the fixing frame 7 are connected by sliding left and right. 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; When the clamping plate 6 abuts against the inner wall of the pipe, the second connecting rod 18 and the threaded rod 12 are in a rotationally connected state, and the slip ring 45 drives the round rod 20 to move downward, and the round rod 20 can abut against the moving cylinder 21 to drive the moving cylinder 21 to move downward. In this process, the side walls of the round rod 20 and the moving cylinder 21 abut against each other, which will form an extrusion effect on the moving cylinder 21, causing the moving cylinder 21 to move downward relative to the second connecting rod 18. Figure 6 , at this time, the moving cylinder 21 drives the second truncated cone 23 to move downward, the moving cylinder 21 compresses the first spring 26, the second truncated cone 23 and the second connecting plate 29 abut against each other and drive the second connecting plate 29 to move downward, while the second connecting plate 29 compresses the second spring 28, the arc block 17 is driven downward by the third connecting rod 27, the arc block 17 and the first truncated cone 31 abut against each other, and the first truncated cone 31 is moved away from the housing 1, the first truncated cone 31 stretches the third spring 33, and the first truncated cone 31 drives the threaded ring 11 to move away from the housing 1, and 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 that moves with the rotating 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 barrel 5 and the housing 1 are slidably connected, the rotating threaded ring 11 will drive the threaded barrel 5 to move relative to the housing 1 until the control ball 43 on the outside of the threaded barrel 5 abuts against the object to be measured, and the control ball 43 abuts against the end face of the threaded barrel 5, and finally completes the measurement operation of the corresponding data. In this process, the center of the pipeline can be determined and the distance between the center of the pipeline and the object to be measured can be measured only 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, Fig.12 As shown, two devices are selected to determine the position between adjacent pipes. If the control balls 43 on the outer sides of the two threaded barrels 5 are against each other, it means that the centers of the two adjacent pipes are on the same horizontal line. In the above-mentioned measurement process, when the control balls 43 and the measured object are against each other, the rotating ring 2 is continuously rotated until the control balls 43 and the threaded barrel 5 that are against the measured object are against each other. During the measurement, the position of the control balls 43 relative to the threaded barrel 5 can be observed, and the connection between the control balls 43 at the other end and the threaded barrel 5 can be obtained. When the rotating rod 8 is stopped, the distance between the center of the pipe and the control balls 43 can be directly read through the scale lines on the outer side of the threaded barrel 5. This is simple and convenient. During the movement of the threaded barrel 5, the round rod 20 is located on the upper side of the moving barrel 21. However, during this process, when the round rod 20 passes through the notch 22, the moving barrel 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 continuing to rotate. Since the round rod 20 is stationary and the moving barrel 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 barrel 21, thereby repeating the above process, so that the threaded barrel 5 will continue to move, which will cause The threaded ring 11 as a whole moves back and forth once relative to the outer shell 1, and the back and forth moving threaded ring 11 as a whole drives the first truncated cone 31 to move. The first truncated cone 31 drives the slide plate 38 to slide left and right once 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 and the outer wall of the pipeline are abutted against each other, thereby forming a knocking effect on the pipeline. After the measurement is completed, it can be observed whether cracks appear at the knocking position. If cracks appear, it means that the quality of the pipeline is poor and needs to be replaced in time. If there is no problem, it can be used normally, and then a simple detection effect of the pipeline quality can be completed during the detection process.
