Description

Technical Field

[0001] The utility model relates to the field of steam turbine monitoring, in particular to a steam turbine operation monitoring device. Background Art

[0002] Steam turbines are key components in modern power generation and power systems, and their operating status is directly related to the stability and safety of the entire system. During long-term operation, steam turbine bases can shift due to various factors, such as temperature fluctuations and mechanical vibration. If this displacement is not monitored and addressed promptly, it can cause machine failures or even accidents. Therefore, real-time monitoring of steam turbine base displacement is crucial for ensuring safe equipment operation. Existing displacement monitoring devices have limitations in terms of accuracy, comprehensiveness, and adaptability. Utility Model Content

[0004] A device for monitoring the displacement of a steam turbine comprises: a fixing base, a pressure monitoring device, and a horizontal laser rangefinder. The base of the steam turbine is fixedly mounted on the mounting position of the fixing base. A plurality of the pressure monitoring devices are arranged around the mounting position and contact the base of the steam turbine. A plurality of vertical rods are arranged above the fixing base, the vertical rods being fixed to a top plate and located outside the mounting position. The horizontal laser rangefinder is arranged at the lower end of the vertical rods and is also located outside the steam turbine. The horizontal laser rangefinder and the pressure monitoring device feed back measured signals to a monitoring system, so that personnel can promptly understand the displacement of the steam turbine and take corresponding measures.

[0005] As a further improvement, the pressure monitoring device consists of a vertical plate, a mounting plate, and a pressure sensor. The vertical plate is fixedly mounted on the fixing seat. A threaded adjustment screw is provided in the middle of the vertical plate. The front end of the adjustment screw is provided with a rotatably connected mounting plate. The pressure sensor is mounted on the front side of the mounting plate. Two symmetrical sliding rods are also provided at the rear of the mounting plate. The sliding rods slide through the vertical plate. The position of the pressure sensor can be adjusted by adjusting the screw to ensure good contact with the turbine base.

[0006] As a further improvement, the vertical rod is a telescopic rod, and a swivel is provided at the lower end of the vertical rod. The horizontal laser rangefinder is horizontally installed on one side of the swivel, and a locking screw is provided on the other side of the swivel. The locking screw cooperates with the swivel thread, so that the height and angle of the horizontal laser rangefinder can be flexibly adjusted to meet different monitoring needs.

[0007] As a further improvement, a slide rail is provided on the top plate, and a plurality of vertical laser rangefinders are provided on the slide rail. The vertical laser rangefinders can slide along the slide rail to increase the distance measurement monitoring in the vertical direction and make the monitoring more comprehensive.

[0008] Beneficial effects: 1. By setting up multiple pressure monitoring devices around the turbine base and combining them with the use of a horizontal laser rangefinder, all-round monitoring of the turbine base displacement can be achieved, improving the accuracy and reliability of monitoring;

[0009] 2. The adjustment screw design in the pressure monitoring device allows the position of the pressure sensor to be adjusted according to actual needs, improving the applicability and flexibility of the device;

[0010] 3. The vertical rod adopts a telescopic rod design, and the horizontal laser rangefinder is installed on the swivel and fixed by a locking screw. This structure not only ensures the stability of measurement, but also facilitates adjustment and maintenance;

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0016] like Figures 1 to 3The device shown is for monitoring the displacement of a steam turbine. The base of the steam turbine (not shown) is fixedly mounted on the mounting position 2 of the fixing base 1. The fixing base 1 can be the ground of the working area or can be regarded as the base of the fixed structure. A plurality of pressure monitoring devices 3 are arranged around the mounting position 2. The pressure monitoring devices 3 are in contact with the base of the steam turbine. The pressure monitoring devices 3 are composed of a vertical plate 31, a mounting plate 32, and a pressure sensor 33. The vertical plate 31 is fixedly mounted on the fixing base 1. The middle part of the vertical plate 31 is provided with a threaded adjustment screw 34. The front end of the adjustment screw 34 is provided with a rotatably connected mounting plate 32.

The position of the pressure sensor 33 can be adjusted by adjusting the screw 34 to ensure good contact with the steam turbine base and record the initial data of each pressure sensor 33.

[0017] Four vertical rods 5 are arranged above the fixed seat 1. The vertical rods 5 are fixed on the top plate 4. The top plate 4 does not contact the fixed seat 1 to avoid the stability of the vertical rods 5 being affected by the vibration of the turbine. The vertical rods 5 are located on the outside of the installation position 2. A horizontal laser rangefinder 6 is provided at the lower end of the vertical rod 5. The horizontal laser rangefinder 6 is also located on the outside of the turbine. The horizontal laser rangefinder 6 can detect the horizontal displacement of the turbine in all directions. The horizontal laser rangefinder 6 and the pressure monitoring device 3 feed back the measured signals to the monitoring system, so that the staff can timely understand the displacement of the turbine and take corresponding measures.

A locking screw 8 is provided on the other side of the swivel 7. The locking screw 8 is threadedly matched with the swivel 7, so that the height and angle of the horizontal laser rangefinder 6 can be flexibly adjusted to meet different monitoring needs.

[0019] A slide rail 9 is also provided on the top plate 4, and a number of vertical laser rangefinders 10 are provided on the slide rail 9. The vertical laser rangefinders 10 can slide along the slide rail 9 to increase the vertical distance measurement monitoring, so that it can monitor whether the turbine will produce excessive vibration amplitude during operation.
