[0029] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] The present invention relates to a water turbine guide mechanism training device, comprising: a bottom ring 1, a shaft sleeve 2, a thrust ring 3, a guide vane 4, a thrust ring 6, a shaft sleeve 7, a shaft sleeve 8, and a top cover 5. The guide vane 4 is rotatably arranged on the bottom ring 1 through the shaft sleeve 2 and the thrust ring 3.

[0031] The top cover 5 is arranged on the guide vane 4 through the thrust ring 2 6 , the shaft sleeve 2 7 and the shaft sleeve 3 8 , and the guide vane 4 is rotatable relative to the top cover 5 .

[0032] Gland 11, anti-wear ring 9 and guide vane arm 10, the lower end of the gland 11 contacts the top of the guide vane 4, the anti-wear ring 9 is inserted into the guide vane 4, the guide vane arm 10 is sleeved on the guide vane 4, and the lower end of the guide vane arm 10 contacts the upper end of the anti-wear ring 9, the bolt 2 13 is threadedly connected to the gland 11 and is rotatably connected to the guide vane 4,

[0033] The equipment body is connected to the pressure cover 11, the top cover 5 and the bottom ring 1 respectively. The bolt 2 13 passes through the pressure cover 11 and is threadedly connected to the guide vane 4, and the bolt 2 13 is rotated to adjust the gap between the guide vane 4 and the bottom ring 1 in the upper and lower directions. The gap measuring component is set on the bottom ring 1 to monitor the distance between the guide vane 4 and the bottom ring 1.

[0034] Specifically, if Figure 1 and Figure 2 As shown, the shaft sleeve 2 and the thrust ring 3 are arranged on the bottom ring 1.

[0035] The guide vane 4 is rotatably mounted on the bottom ring 1 through the shaft sleeve 2 and the thrust ring 3. The top cover 5 is seated on the guide vane 4 through the thrust ring 6, the shaft sleeve 7 and the shaft sleeve 8. The anti-wear ring 9 is sleeved on the shaft of the guide vane 4. The guide vane arm 10 is sleeved in the shaft of the guide vane 4 and is installed on the anti-wear ring 9 through the pressure cover 11, the bolt 12, the bolt 2 13 and the pin 14.

[0036] The guide vane arm 10 is sleeved on the guide vane 4, the lower end of the guide vane arm 10 contacts the anti-wear ring 9, the lower end of the anti-wear ring 9 contacts the upper end of the top cover 5, the second bolt 13 is threadedly connected to the pressure cover 11, and the second thread passes through the pressure cover 11 and is rotatably connected to the guide vane 4. By turning the second bolt 13 by the handle, the position of the guide vane 4 in the vertical direction can be adjusted, thereby adjusting the gap between the guide vane 4 and the bottom ring 1 in the vertical direction.

[0037] The gap measurement component is set on the bottom ring 1 to monitor the distance between the bottom ring 1 and the guide vane 4 in the vertical direction.

[0038] The trainee adjusts the vertical spacing of the guide vanes 4 by turning the second bolt 13. After the guide vanes 4 move vertically, the spacing measuring assembly measures whether the gap after rotation is within a preset range. For example, the trainee can turn the second bolt 13 by using a handle.

[0039] Furthermore, the installation of the guide vane can be simulated by disassembling the sleeve 2, the guide vane arm 10, the pressure cover 11, the bolt 12, the bolt 2 13, the pin 14, the thrust ring 3 and the guide vane 4 to achieve the purpose of training without waiting for the unit maintenance.

[0040] The present application provides a training device for a water turbine guide mechanism. By simulating the actual structure of a water turbine, for example, by setting a bolt 2 13, rotating the bolt 2 13 to change the spacing of the guide vanes 4 in the vertical direction, and measuring the gap after rotation by a spacing measurement component to see if it is within a preset range, the training device can be used to facilitate maintenance training and evaluation for trainees. Compared to the existing technology that uses on-site teaching demonstrations, the water turbine guide mechanism training device of the present application does not require on-site teaching demonstrations and operations, avoiding operational errors that lead to equipment abnormalities and the dangers caused by abnormal operations. At the same time, when the equipment is running, due to the noise generated by the equipment operation, on-site teaching and promotion cannot be clearly conveyed to the trainees. The present application imitates the existing water turbine and sets spacing measurement and screw 2 for teaching and training to avoid teaching in an environment where the water turbine is running, avoiding a noisy environment and thus improving the teaching quality. At the same time, the present application can start teaching at any time without waiting for unit maintenance. By arranging components such as the bottom ring, sleeve 1, thrust collar 1, thrust collar 2, sleeve 2, sleeve 3, top cover, gland, anti-wear ring, and guide vane arm, trainees can easily simulate and train on the turbine structure. Furthermore, by disassembling sleeve 12, guide vane arm 10, gland 11, bolt 12, bolt 2 13, pin 14, thrust collar 3, and guide vane 4, the actual turbine structure can be simulated to teach guide vane installation, achieving the purpose of training without having to wait for unit maintenance.

[0041] At the same time, the equipment of the present application occupies a smaller area than the actual turbine, and the station area is small, which saves the actual manufacturing cost of the training equipment.

[0042] In some embodiments, the water turbine water guide mechanism training device further includes an adjustable connecting plate 15, a shaft sleeve 16 and a scissor pin 17, and the adjustable connecting plate 15 is connected to the guide vane arm 10 through the shaft sleeve 16 and the scissor pin 17;

[0043] The shaft sleeve 5 18 and the control ring 19, the shaft sleeve 5 18 is mounted on the control ring 19, and the control ring 19 is rotatably arranged on the top cover 5,

[0044] The adjustable connecting plate 15 is rotatably connected to the control ring 19 through screws 21 and washers 22.

[0045] like Figure 1 and Figure 2As shown, one end of the adjustable connecting plate 15 is connected to the guide vane arm 10, which is provided on the guide vane 4. The control ring 19 is connected to the guide vane arm 10 to rotate the adjustable connecting plate 15, thereby driving the guide vane 4 to rotate to adjust the opening and closing angle of the guide vane 4. The adjustable connecting plate 15 is connected to the guide vane arm 10 via a fourth shaft sleeve 16 and a scissor pin 17. The output end of the relay is connected to the control ring 19, which drives the control ring 19 to rotate to adjust the rotation angle of the control ring 19. A person can then operate the rotation of the control ring 19 to control the switching value of the guide vane 4. A matching gap measurement component can monitor the gap value after adjustment in real time and determine whether it is within a preset range. This allows the trainee to monitor whether the operation is within the preset range, replacing on-site teaching and avoiding equipment damage or personal danger caused by operational errors. At the same time, it eliminates on-site noise interference and ensures stable training activities.

[0046] In some embodiments, the pressure ring 28 is mounted on the top cover 5 via three bolts 29. Mounting the pressure ring 28 on the top cover 5 via three bolts 29 can limit the movement of the control ring 19. This prevents the control ring 19 from rotating beyond its range, potentially damaging the training device, and improves the stability of the device.

[0047] In some embodiments, the water turbine water guide mechanism training equipment further includes a relay, a scale plate 23 and a pointer 26, the scale plate 23 is mounted on the control ring 19, the pointer 26 is mounted on the top cover 5, and the relay is extended to drive the control ring 19 to rotate.

[0048] Specifically, the servo output is connected to the control ring 19. The servo output extends and retracts to drive the control ring 19's rotation. Its output is hinged to the outer edge of the control ring 19 via a pin. This retracting motion drives the control ring 19 to reciprocate around the central axis of the top cover 5. This replicates the hydraulic transmission process for adjusting the opening of a turbine guide vane 4, preventing trainees from malfunctioning the control ring 19 due to improper direct manipulation of the high-pressure hydraulic system, thereby improving safety during training.

[0049] Furthermore, the gap measurement assembly also includes a first distance monitoring component. A groove is provided on the bottom ring 1. The first distance monitoring component is arranged in the groove of the bottom ring 1. The first distance monitoring component is suitable for monitoring the gap between the bottom ring 1 and the guide vane 4.

[0050] For example, a first distance monitoring component is provided at a position of the bottom ring 1 corresponding to the guide vane 4. The first distance monitoring component is suitable for monitoring the distance between the bottom ring 1 and the guide vane 4 in the up and down directions. The first distance monitoring component is provided in a groove of the bottom ring 1, thereby preventing the guide vane 4 from damaging the first distance monitoring component due to rotation or movement.

[0051] In some embodiments, the first distance monitoring component includes a first distance sensor and a first display screen. The first distance sensor is provided on the bottom ring 1 to monitor the distance between the bottom ring 1 and the guide vane 4. The output end of the first distance sensor is connected to the first display screen. The first display screen is provided to display the distance data between the bottom ring 1 and the guide vane 4, thereby facilitating the determination of whether the adjustment action of the operating bolt 2 13 is in compliance with the standard, thereby improving the interactivity of teaching and training.

[0052] Furthermore, there are multiple first distance sensors and multiple guide vanes 4, and the first distance sensors correspond one to one with the guide vanes 4. This facilitates simultaneous adjustment of the vertical positions of the multiple guide vanes 4 and also facilitates leveling of the entire guide vane 4 so that the multiple guide vanes 4 are in the same plane.

[0053] In some embodiments, the gap measurement assembly further includes a second distance monitoring component, which is disposed on the top cover 5 and is suitable for monitoring the gap between the top cover 5 and the guide vane 4 .

[0054] Furthermore, the second distance monitoring component includes a second distance sensor and a second display screen. The second distance sensor is installed on the top cover 5 to monitor the distance between the top cover 5 and the guide vane 4. The output end of the second distance sensor is connected to the second display screen. The vertical distance between the top cover 5 and the guide vane 4 also needs to be adjusted. Therefore, when adjusting the vertical distance between the guide vane 4 and the bottom ring 1, the vertical position of the guide vane 4 and the pressure cover 11 can also be adjusted.

[0055] Furthermore, there are multiple second distance sensors, and there are multiple guide vanes 4 , and the second distance sensors correspond to the guide vanes 4 one-to-one.

[0056] Furthermore, during the practical training, by inspecting the bottom ring 1, the shaft sleeve 2, and the thrust ring 3, simulating scratches or high spots on the bottom ring 1 and the shaft sleeve 2, and using sandpaper, oilstone, file and other tools to process them, the bottom ring 1 maintenance training function can be realized.

[0057] During the training process, the guide vane 4 is placed in a completely free movement state, and the guide vane 4 is tied tightly using a hand hoist and binding rope. The vertical clearance of the guide vane 4 is checked with a feeler gauge to ensure that it meets the relevant national standards, thereby achieving the guide vane 4 binding training function.

[0058] During the training process, you can also use a feeler gauge to check the gap between the guide vane 4 and the bottom ring 1, and the guide vane 4 and the top cover 5. For the end face gap that does not meet the standard, use the wrench to adjust the bolt 2 13 to achieve the purpose of moving the guide vane 4 up and down, and use the feeler gauge again to check the gap between the guide vane 4 and the bottom ring 1, and the guide vane 4 and the top cover 5 until the end face gap of the guide vane 4 meets the standard, which can realize the guide vane end face gap measurement and adjustment training function.

[0059] During the training process, use a feeler gauge to check the vertical clearance of the guide vane 4. For the vertical clearance that does not meet the standard, calculate the adjustment amount of the vertical clearance of each guide vane 4. At the lower end of the water-facing surface of each adjusted guide vane 4, use a dial indicator to set up and fix it on the bottom ring 1, adjust the adjustable connecting plate 15 and monitor the adjustment amount of the vertical clearance of the guide vane 4. When the gap adjustment amount reaches the calculated vertical clearance adjustment amount of the guide vane 4, use a feeler gauge to check the vertical clearance of the guide vane 4 again until the vertical clearance meets the standard. The guide vane vertical clearance measurement and adjustment training function can be realized.

[0060] During the training process, the guide vane 4 is simulated to have cavitation or scratches, burrs and other defects on the end face. The defects are processed using tools such as grinders, sandpaper, oilstones, and files, which can realize the guide vane 4 maintenance training function.

[0061] During the training process, the top cover 5, thrust ring 2 6, shaft sleeve 2 7, and shaft sleeve 3 8 are checked, and defects such as cavitation, scratches, and burrs are simulated on the top cover 5, shaft sleeve 2 7, and shaft sleeve 3 8. The defects are processed using tools such as grinders, sandpaper, oilstones, and files, which can realize the maintenance training function of the top cover 5.

[0062] During the training process, by disassembling and assembling the anti-wear ring 9, guide vane arm 10, pressure cover 11, bolt one 12, bolt two 13, pin one 14, adjustable connecting plate 15, shaft sleeve four 16, scissor pin 17, shaft sleeve five 18, control ring 19 and other components, check whether each component has defects such as component damage, scratches, burrs, etc., use sandpaper, oilstone, file and other tools to deal with the defects, and replace the damaged parts, so as to realize the disassembly and assembly training function of the water guide mechanism.

[0063] The above is a detailed introduction to the method provided by the present application.
