Description

Technical Field

[0001] This application relates to the technical field of water distribution ring pipe installation measurement, and in particular to a distance measurement conversion device. Background Technology

[0002] The distribution ring pipe is a core component of a bucket turbine generator set. As a key pressure-bearing component located between the inlet ball valve and the turbine runner, its main function is to uniformly and symmetrically introduce water into each nozzle, driving the runner to rotate stably. With continuous advancements in domestic technology, the size and weight of the distribution ring pipe are constantly increasing, as is the distance between the center of the bucket turbine generator set and the measuring surface of the distribution ring pipe. In existing technology, there is a 68.4° angle between the center of the distribution ring pipe and the flange face of the distribution ring pipe branch. When measuring the distance between the center of the distribution ring pipe and the flange face of the distribution ring pipe branch, the traditional method is to use the center of the distribution ring pipe as a reference, drawing multiple piano lines parallel to the flange faces of each distribution ring pipe branch, and then using a measuring tape to measure the straight-line distance from the flange face of the distribution ring pipe branch to the piano lines.

[0003] However, the manual measurement method using piano wire and measuring tape inevitably suffers from large measurement errors. In addition, there is a 68.4° angle between the center of the water distribution ring pipe and the flange face of the water distribution ring pipe branch pipe, making the conversion of measurement values ​​difficult and inaccurate. This results in low accuracy of the measurement results and low measurement efficiency, which greatly restricts the installation period and quality of the water turbine generator set. Utility Model Content

[0004] Therefore, it is necessary to provide a distance measurement conversion device to address the problems of high measurement difficulty, low accuracy and efficiency of traditional technologies.

[0005] This application discloses a distance measurement conversion device, which includes:

[0006] Mounting flange, which is used to be installed on the flange face of the water distribution ring pipe branch pipe;

[0007] A rotating component, which is connected to the mounting flange; and

[0008] A measuring flange is provided on the side of the mounting flange away from the branch pipe of the water distribution ring. The measuring flange is connected to the rotating member and can rotate relative to the mounting flange by means of the rotational freedom provided by the rotating member, so that the measuring flange is perpendicular to the laser rangefinder located at the center of the water distribution ring. A measuring line is provided on the side of the measuring flange away from the mounting flange, and the measuring line is used to cooperate with the laser rangefinder for measurement.

[0009] In this solution, the distance measurement conversion device is simultaneously installed with the flange face of the water distribution ring pipe branch pipe. This allows the entire distance measurement conversion device to be assembled onto the water distribution ring pipe branch pipe. Utilizing the rotational freedom provided by the rotating component, the measuring flange can be rotated relative to the installation flange. This changes the angle between the measuring flange and the center of the water distribution ring pipe from 68.4° to a perpendicular orientation. Consequently, the measuring line on the measuring flange is aligned perpendicularly to the laser rangefinder installed at the center of the water distribution ring pipe. The laser rangefinder then automatically calculates the distance... By measuring the time it takes for the light to travel to and from the measuring line, the distance from the center of the water distribution ring pipe to the measuring flange can be calculated. This converts the original 68.4° measuring angle to a 90° measurement. Since the opening angle between the measuring flange and the installation flange is known to be 21.6°, the distance between the center of the water distribution ring pipe and the center of the flange face of the water distribution ring pipe branch can be accurately obtained after conversion. This method of calculation and measurement based on vertical angle is easier to implement and has higher calculation accuracy, which can greatly improve measurement efficiency and ensure the installation schedule and quality of the water turbine generator set.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] See Figure 1 This application illustrates a distance measurement conversion device 100, which is used to measure the distance from the center of the water distribution ring pipe to the flange face of the water distribution ring pipe branch pipe, so as to check the installation position accuracy of each water distribution ring pipe branch pipe.

[0034] Specifically, the water distribution ring pipe has six water distribution ring pipe branches, which are arranged circumferentially around the outer periphery of the center of the water distribution ring pipe.

[0035] Please continue reading. Figure 1 For example, the distance measurement conversion device 100 includes a mounting flange 10, a rotating member 20, and a measuring flange 30. The mounting flange 10 is mounted on the flange surface of the branch pipe of the water distribution ring pipe; the rotating member 20 is connected to the mounting flange 10; the measuring flange 30 is arranged on the side of the mounting flange 10 away from the branch pipe of the water distribution ring pipe, the measuring flange 30 is connected to the rotating member 20, and can rotate relative to the mounting flange 10 by means of the rotational freedom provided by the rotating member 20, so that the measuring flange 30 is perpendicular to the laser rangefinder arranged at the center of the water distribution ring pipe, and a measuring line 40 is provided on the side of the measuring flange 30 away from the mounting flange 10, the measuring line 40 is used to cooperate with the laser rangefinder for measurement.

[0036] Based on the above embodiments, the rotating component 20 includes a rotating shaft, a first connecting component, and a second connecting component. One end of the first connecting component is connected to the mounting flange 10, and the other end of the first connecting component is rotatably connected to the rotating shaft. One end of the second connecting component is connected to the measuring flange 30, and the other end of the second connecting component is rotatably connected to the rotating shaft.

[0037] Understandably, the first and second connectors can rotate relative to each other through the rotational freedom provided by the rotating shaft. When not installed, the first and second connectors are closed together so that the mounting flange 10 and the measuring flange 30 are close together, saving packaging materials and installation space, and facilitating transportation and use.

[0038] During installation, first fix the mounting flange 10 to the flange face of the water distribution ring pipe branch pipe, and then pull the measuring flange 30 to rotate away from the mounting flange 10. This will change the included angle of the measuring flange 30 from 68.4° to a perpendicular arrangement with the laser rangefinder at the center of the water distribution ring pipe, thereby reducing the difficulty of measurement and numerical conversion and improving the accuracy of measurement results.

[0039] Optionally, the rotating component 20 can be any type of hinge, such as a hinge, and can be flexibly selected according to actual needs.

[0040] It should be noted that after the measuring flange 30 and the mounting flange 10 have been rotated away from each other and adjusted to their correct positions, the rotating part 20 can be welded and fixed to the mounting flange 10 and the measuring flange 30 to ensure structural stability.

[0041] Please continue reading. Figure 1 Furthermore, based on any of the above embodiments, the distance measurement conversion device 100 also includes a support member 50, one end of which is connected to the mounting flange 10, and the other end of which is connected to the measuring flange 30.

[0042] The support member 50 is vertically or inclinedly connected between the mounting flange 10 and the measuring flange 30 to provide additional support and positioning for the measuring flange 30, which helps to improve the structural stability and reliability of the measuring flange 30 and the mounting flange 10.

[0043] For example, the support member 50 can be a metal component such as iron plate or angle steel, and can be installed and fixed to the mounting flange 10 and measuring flange 30 by any one of the following methods: screw connection, welding, snap connection, or plug connection. The specific method can be flexibly selected according to actual needs.

[0044] Furthermore, the number of support members 50 can be more than one. When two or more support members 50 are provided at the same time, they are arranged at intervals along the outer periphery of the mounting flange 10 and the measuring flange 30 to form a more stable and uniform support effect.

[0045] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: When the distance measurement conversion device 100 of this solution is used, the mounting flange 10 is simultaneously connected to the flange face of the water distribution ring pipe branch pipe, so as to realize the overall assembly of the distance measurement conversion device 100 onto the water distribution ring pipe branch pipe. With the help of the rotational freedom provided by the rotating component 20, the measuring flange 30 can be rotated relative to the mounting flange 10, thereby changing the angle between the measuring flange 30 and the center of the water distribution ring pipe from 68.4° to a perpendicular setting to the center of the water distribution ring pipe. In this way, the measuring line 40 on the measuring flange 30 can be aligned with the laser measuring line installed at the center position of the water distribution ring pipe. The laser rangefinder is vertically positioned, and automatically calculates the time it takes for the measuring light to travel to and from the measuring line 40. This allows for the calculation of the distance from the center of the water distribution ring pipe to the measuring flange 30, effectively converting the original 68.4° measuring angle to a 90° measurement. Since the opening angle of 21.6° between the measuring flange 30 and the mounting flange 10 is known, the distance between the center of the water distribution ring pipe and the center of the flange face of the water distribution ring pipe branch pipe can be accurately obtained after conversion. This method of calculation and measurement based on vertical angle is easier to implement and has higher accuracy, thus greatly improving measurement efficiency and ensuring the installation schedule and quality of the water turbine generator unit.

[0046] Please continue reading. Figure 2 In one optional embodiment, the mounting flange 10 is an annular body. More specifically, the mounting flange 10 is an annular body, which is easy to process and shape, and facilitates installation by fitting it to the flange face of the water distribution ring pipe branch.

[0047] The mounting flange 10 has multiple spaced mounting through holes 11 arranged circumferentially. These mounting through holes 11 are designed to correspond one-to-one with the threaded holes on the branch pipe of the water distribution ring pipe. Therefore, during installation, the mounting through holes 11 are aligned with the threaded holes, and the threaded component is passed through the mounting through holes 11 and screwed into the threaded holes to thread the mounting flange 10 onto the flange face. This installation method is simple, provides high connection strength, is highly feasible, and helps improve the efficiency of measurement operations.

[0048] For example, threaded components can be, but are not limited to, screws, bolts, etc.

[0049] Furthermore, in order to reduce the overall weight of the distance measurement conversion device 100 and facilitate installation and operation, based on any of the above embodiments, the mounting flange 10 is also provided with a first weight reduction groove 12, which is arranged through the thickness direction of the mounting flange 10.

[0050] For example, the first weight-reducing groove 12 can be any of the following structural shapes: rectangular, trapezoidal, or fan-shaped. In this application, three first weight-reducing grooves 12 are provided and are evenly spaced along the circumference of the mounting flange 10, which further enhances the weight-reduction effect while ensuring that the mounting flange 10 has sufficient structural strength.

[0051] In another embodiment, the center hole of the mounting flange 10 is further provided with a positioning protrusion ring 13, which protrudes toward the flange face of the water distribution ring pipe branch. During installation, the positioning protrusion ring 13 can be fitted into the positioning hole pre-set on the flange face of the water distribution ring pipe branch to form a positioning effect on the mounting flange 10, thereby helping to improve the stability of the mounting flange 10 installation, while ensuring the alignment accuracy of the mounting through hole 11 and the threaded hole, thus balancing the installation accuracy and efficiency of the mounting flange 10.

[0052] Please continue reading. Figure 3 In another embodiment, the measuring flange 30 includes an annular body 31, and the measuring line 40 includes a first measuring line 40a disposed on the annular body 31. More specifically, the annular body 31 is a circular ring. The first measuring line 40a is a cross-shaped line disposed on the surface of the annular body 31 facing the laser rangefinder. This first measuring line 40a can be used as a measuring reference to calibrate the specific position of the measuring light reaching the measuring surface of the measuring flange 30.

[0053] Optionally, the first measuring line 40a can be a cross-shaped groove formed on the surface of the measuring flange 30 by machining, chemical etching or other processing methods; or the cross-shaped part can be installed on the measuring flange 30 by gluing or other methods. The choice can be made flexibly according to actual needs.

[0054] Furthermore, in order to reduce the overall weight of the distance measurement conversion device 100 and facilitate installation and operation, based on the above embodiment, the annular body 31 is provided with a second weight reduction groove 311, which is arranged through the thickness direction of the annular body 31.

[0055] For example, the second weight-reducing groove 311 can be any of the following structural shapes: rectangular, trapezoidal, or fan-shaped. In this application, eight second weight-reducing grooves 311 are provided and are evenly spaced along the circumference of the annular body 31, which further enhances the weight-reduction effect while ensuring that the annular body 31 has sufficient structural strength.

[0056] Please continue reading. Figure 3 Furthermore, based on the above embodiments, the measuring flange 30 also includes a skeleton body 32, which is installed in the annular cavity of the annular body 31, and the measuring line 40 also includes a second measuring line 40b, which is disposed on the skeleton body 32.

[0057] Specifically, the skeleton 32 is a cross-shaped structure, forming four connections with the inner ring wall of the annular body 31. In this case, the skeleton 32 can act as a supporting skeleton for the annular body 31, improving the overall structural strength and stability of the measuring flange 30. For example, the skeleton 32 can be integrally formed with the annular body 31, or it can be detachably assembled with the annular body 31, which can be flexibly selected according to actual needs.

[0058] Of course, in other alternative embodiments, the skeleton 32 can also be a triangular structure, a trapezoidal structure, or other shapes.

[0059] Furthermore, in order to reduce the overall weight of the distance measurement conversion device 100 and facilitate installation and operation, based on the above embodiment, the frame body 32 is provided with a third weight reduction groove 321, which is arranged through the thickness direction of the frame body 32.

[0060] For example, four third weight-reduction grooves 321 are provided on the horizontal and vertical parts of the cross-shaped skeleton 32 to achieve a better weight reduction effect while meeting the necessary structural strength.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
