Abstract
Description
Technical Field

[0002] Hydropower station generating units are the core equipment of a hydropower station, consisting of a turbine and a generator. The turbine uses the energy of water flow to drive the generator, converting water energy into electrical energy. There are various types of turbines, including impulse turbines and reaction turbines, each with different applicable heads and operating conditions to meet the power generation needs of various hydropower stations. Real-time monitoring of key parameters such as vibration, sway, temperature, and pressure is crucial for timely detection of abnormalities, such as bearing overheating or loose components, and for minimizing equipment damage and accidents.
[0003] In existing technologies, detection modules are often installed at the upper guide bearing, lower guide bearing, and water guide bearing of a water turbine. The modules are installed on the side or bottom of the bearing housing and can detect the vibration of the bearing in different directions to reflect the bearing wear, lubrication condition, and shaft alignment. However, before fixing the detection modules, such as related sensors, we need to adjust the orientation angle of the sensors to obtain the most accurate data. Existing technologies lack dedicated debugging fixtures. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0029] Example 1, referring to Figures 1-3 This is the first embodiment of the present invention. This embodiment provides an adjustment mechanism, including a support structure 1. The support structure 1 includes a mounting plate 11 and fixing bolts 12 disposed on the outer wall of the mounting plate 11. The adjustment mechanism fixes the mounting plate 11 to the side of the shaft to be tested using the fixing bolts 12; and...
[0030] The adjustment component 2, located on the side of the support structure 1, can adjust the position and angle of the part to be inspected, making it easier for staff to find a suitable inspection position; and...
[0031] The support member 3 is located on the side of the adjustment member 2. The support member 3 works in conjunction with the adjustment member 2 to provide stable support for the detection part during movement.
[0032] Usage process: When using a vibration sensor to detect the vibration of the shaft, the measuring point can be set at the bearing or the machine housing mounting point to better reflect the operating status of the equipment. When installing the detection device, first use the adjusting component 2 to adjust the position and angle of the support component 3 and the detection parts on the support component 3. Read the detection data at multiple positions and angles, and compare the data at different positions to determine the optimal detection position.
[0033] Example 2, refer to Figures 1-3 This is the second embodiment of the present invention. Unlike the previous embodiment, a connecting rod is provided on the side of the mounting plate 11, and a rotating plate is provided at the end of the connecting rod away from the mounting plate 11. Figure 2 As shown, the top of the connecting rod is rotatably connected to the mounting plate 11, and the rotating plate and the connecting rod can rotate relative to each other. Multiple sets of connecting rods and rotating plates are provided.
[0034] Furthermore, the adjusting component 2 includes a cross support plate 21 connected to the rotating plate. The side of the cross support plate 21 has a receiving groove 23. Each end of the cross support plate 21 has an extension plate 22. The side of the extension plate 22 is rotatably connected to a first arc plate 24. A sliding groove is formed in the middle of the first arc plate 24. A motor 25 is installed at one end of the first arc plate 24. The output shaft of the motor 25 is connected to the first arc plate 24. Figure 2 As shown, the first arc plate 24 is rotatably connected to the extension plate 22, and the operation of the motor 25 will drive the first arc plate 24 to rotate on the extension plate 22.
[0035] Furthermore, a telescopic rod is provided on the side of the cross support plate 21 away from the first arc plate 24. The end of the telescopic rod away from the cross support plate 21 is connected to the mounting plate 11. When the telescopic rod extends, it will cause the cross support plate 21 to move away from the mounting plate 11. When the telescopic rod retracts, it will cause the cross support plate 21 to move closer to the mounting plate 11.
[0036] Furthermore, the support member 3 includes a rotating rod 31, one end of which is rotatably connected to the receiving groove 23. The rotating rod 31 is sleeved in the receiving groove 23, allowing relative rotation between it and the cross support plate 21. A sliding rod 32 is sleeved on the outer wall of the rotating rod 31, allowing it to slide. The detection part is fixed on the sliding rod 32, and its movement causes the detection part to move. The end of the sliding rod 32 away from the rotating rod 31 is engaged with the inner wall of the first arc plate 24. When the motor 25 rotates, it causes the first arc plate 24 to move on the cross support plate 21. Shaking will cause the slide bar 32 to shake as well, thereby changing the angle between the slide bar 32 and the cross support plate 21, that is, changing the angle between the part to be tested and the surface to be tested, making it convenient for the staff to adjust the testing angle. Preferably, a second arc plate 26 is provided on the side of the first arc plate 24 away from the cross support plate 21. The inner diameter of the second arc plate 26 is slightly larger than the inner diameter of the first arc plate 24. The second arc plate 26 and the first arc plate 24 are arranged perpendicularly and alternately. A motor 25 is provided on the side of the second arc plate 26. The rotation of the second arc plate 26 will also cause the slide bar 32 to shake, thereby causing the part to be tested to shake.
[0037] Usage: When installing the test part, the telescopic rod moves the cross support plate 21 closer to or away from the mounting plate 11, and moves the slide rod 32 and the test part on the slide rod 32 closer to or away from the surface to be tested, thereby adjusting the test position. The motor 25 drives the arc plate to shake, which can adjust the test angle and test position of the test part. This structure can easily adjust the position and angle of the test part, making it convenient for staff to confirm the optimal test position.
[0038] Example 3, referring to Figures 1-3 This is the third embodiment of the present invention. This embodiment further provides a monitoring device for a hydropower station unit, including an adjustment mechanism; and a detection module 4 disposed on the side of the adjustment member 2. The detection module 4 includes a sensor, a data acquisition unit, and a central processing unit. The sensor measures the vibration displacement of the bearing. The data acquisition unit converts the processed analog signal into a digital signal for further analysis. The central processing unit analyzes and processes the collected vibration data and extracts characteristic parameters. The sensor is fixedly installed at the end of the slide bar 32 and moves together with the slide bar 32.
[0039] Furthermore, a display module 5 is provided on the side of the mounting plate 11. During debugging, the detected data is transmitted to the display module 5. The data collected multiple times are compared on the display module 5, and the staff finally confirms the most suitable detection position.
[0040] Usage process: When the position and angle of the sensor are adjusted using the adjustment mechanism, the detected data is transmitted to the display module 5. The data collected multiple times are compared on the display module 5 to facilitate the final confirmation of the detection position.
