Description

Technical Field

[0001] This utility model relates to the field of steam turbine control system technology, specifically to a steam turbine operation control device for power plants. Background Technology

[0002] The turbine control unit in a power plant is a core component of the turbine control system, undertaking key functions such as turbine startup, shutdown, operation regulation, and safety protection.

[0003] However, most control devices currently in use adopt a rigid fixed installation method, which lacks flexibility in structural design. This makes disassembly difficult during equipment inspection, maintenance or upgrade, which not only prolongs downtime but also increases the complexity and safety risks of maintenance work, thereby affecting the overall operating efficiency and maintenance economy of the power plant.

A second motor is mounted on the guide frame, and the drive end of the second motor is connected to the lead screw. The cylinder is movably mounted on the base frame, and a connecting frame is mounted on the rotating frame and is movably connected to the drive end of the cylinder.

[0011] Preferably, the slider is adapted to the guide frame.

This effectively ensures the installation stability and connection reliability of the controller in complex vibration environments, avoids control signal interruption or equipment failure due to loosening, and improves the efficiency of equipment maintenance and operational safety, providing a solid foundation for continuous and stable operation in industrial sites. By adjusting the components, the motor-driven screw mechanism enables the smooth lifting and lowering of the controller body, and combined with the cylinder-driven linkage mechanism, it allows for flexible adjustment of its display angle. This effectively improves the controller's position adaptability and human-machine interaction experience under different working conditions and operational requirements, ensuring that operators can monitor and operate from the best perspective. It also enhances the flexibility and overall coordination of the equipment layout, providing a reliable guarantee for efficient and stable control operations. Through a pair of limit components, the threaded rod drives the slider and lever composite mechanism to achieve precise mechanical engagement between the end of the rotating frame and the guide frame slot. This effectively ensures the rigid locking and vibration resistance of the moving frame in the predetermined position, avoiding displacement deviation of the controller body caused by external disturbances or equipment operation. It significantly improves the reliability of control signal transmission and the continuity of long-term equipment operation, while also enhancing the overall structure's self-adaptive locking capability and operational safety.

The double-ended threaded rod 3 rotates, which can drive the pair of clamping frames 5 to move closer together. The pair of clamping frames 5 can move on the fixed rod 4 and abut against the two side walls of the controller body 26, thereby clamping and fixing the controller body 26.

[0023] Advantageously, the base frame 1 is provided with reinforcing ribs, which increases the stability of the base frame 1.

[0024] Advantageously, the drive assembly includes a first gear 6 and a first motor 7.

The drive end of the first motor 7 is provided with a second gear 8, and the second gear 8 meshes with the first gear 6 to drive the first motor 7. The first motor 7 can drive the second gear 8 to rotate, and the second gear 8 can drive the first gear 6 to rotate. The first gear 6 drives the double-ended threaded rod 3 to rotate.

[0025] Advantageously, the first motor 7 is fixed to the mounting bracket 2 by bolts, and the first motor 7, which is mounted on the mounting bracket 2 by bolts, is easy to install and remove.

[0026] Advantageously, the adjusting assembly includes a rotating shaft 9 and a cylinder 17. The rotating shaft 9 is movably mounted on the base frame 1. A rotating frame 10 is mounted on the rotating shaft 9. A guide frame 11 is mounted on the rotating frame 10. A slider 12 is mounted on the guide frame 11. A moving frame 13 is mounted on the slider 12. A transmission block 16 is mounted on the moving frame 13. A lead screw 14 is movably mounted on the guide frame 11 and is movably connected to the transmission block 16. A second motor 15 is mounted on the guide frame 11, and the driving end of the second motor 15 is connected to the lead screw 14. The cylinder 17 is movably mounted on the base frame 1. The rotating frame 10 is equipped with a connecting frame 18, which is movably connected to the drive end of the cylinder 17. When the position of the controller body 26 needs to be adjusted, the second motor 15 is driven. The second motor 15 can drive the lead screw 14 to rotate. The transmission block 16 drives the moving frame 13 to move under the action of the lead screw 14. The moving frame 13 moves stably on the guide frame 11 through the slider 12, thereby adjusting the height of the controller body 26. The cylinder 17 is driven, which can drive the connecting frame 18 to rotate. The connecting frame 18 can drive the rotating frame 10 to rotate the rotating shaft 9, thereby adjusting the display angle of the controller body 26 for easy operation.

[0027] Advantageously, the slider 12 is adapted to the guide frame 11, and the adapted slider 12 moves stably on the guide frame 11.

One end of the rotating frame 24 with the movable wheel 25 moves away from the mounting frame 20, and the other end of the rotating frame 24 moves towards the mounting frame 20 until it enters the slot 19 on the guide frame 11, thereby fixing and limiting the position of the movable frame 13 and stabilizing the controller body 26.

[0029] Advantageously, the end of the rotating threaded rod 22 away from the sliding block 21 is provided with a rotating handle, which facilitates the rotation of the rotating threaded rod 22.

[0030] Working principle of this utility model:

[0031] First, when the controller body 26 needs to be fixed, it is placed between a pair of clamping frames 5. The first motor 7 is driven, which drives the second gear 8 to rotate. The second gear 8 drives the first gear 6 to rotate, which in turn drives the double-ended threaded rod 3 to rotate. The double-ended threaded rod 3 causes the pair of clamping frames 5 to move closer together. The pair of clamping frames 5 can move on the fixed rod 4 and abut against the side walls of the controller body 26, thus clamping and fixing the controller body 26. When the position of the controller body 26 needs to be adjusted, the second motor 15 is driven, which drives the lead screw 14 to rotate. The transmission block 16, under the action of the lead screw 14, drives the moving frame 13 to move. The moving frame 13 moves stably on the guide frame 11 via the slider 12, thus allowing the controller body 26 to be adjusted. The height is adjusted by driving cylinder 17, which in turn drives connecting frame 18 to rotate. Connecting frame 18 drives rotating frame 10 to rotate rotating shaft 9, thereby adjusting the display angle of controller body 26 for easy operation. When it is necessary to fix the position of moving frame 13, after moving frame 13 moves to the predetermined position, rotating threaded rod 22 is rotated. Rotating threaded rod 22 drives sliding block 21 to move on mounting frame 20. At this time, moving wheel 25 on rotating frame 24 moves on sliding block 21. One end of rotating frame 24 with moving wheel 25 moves away from mounting frame 20, and the other end of rotating frame 24 moves towards mounting frame 20 until it enters the slot 19 on guide frame 11, thereby fixing and limiting moving frame 13 to stabilize controller body 26.
