When the driven wheel 33 rotates, the handle of the hand wheel 4 is driven to rotate around the rotating axis of the hand wheel 4, that is, the hand wheel 4 can be remotely controlled to rotate by controlling the operation of the driving component 3. When facing a valve with a long stroke and a high position in the system, remotely controlling the rotation of the hand wheel 4 through the driving component 3 can reduce the work intensity of the staff and improve the maintenance efficiency.

The driving wheel 32 is connected to the output end of the rotating driving member 31. The driving wheel 32 rotates around a second rotating axis. The second rotating axis is the rotating axis of the rotating driving member 31. The synchronous belt 34 is arranged between the driving wheel 32 and the driven wheel 33. The driving wheel 32 drives the driven wheel 33 to rotate through the synchronous belt 34. The driven wheel 33 rotates around the first rotating axis. The driven wheel 33 is connected to one end of the active rod 21. The driven wheel 33 can drive the active rod 21 to rotate around the first rotating axis. The first rotating axis is parallel to the second rotating axis, thereby ensuring that the driven wheel 33 rotates synchronously with the driving wheel 32.

[0047] Optionally, the driving wheel 32 and the driven wheel 33 are both gear structures, the synchronous belt 34 is a chain structure, and the synchronous belt 34 meshes with the driving wheel 32 and the driven wheel 33 to ensure that the driven wheel 33 has sufficient torque to drive the active rod 21 to rotate.

The height position of the driven wheel 33 is adjusted by changing the position of the mounting wheel 35 in the arc-shaped mounting groove 111 to adapt to the handwheel 4 at different heights. Since the arc-shaped mounting groove 111 takes the second rotating axis as the axis, when the mounting wheel 35 is at any position in the arc-shaped mounting groove 111, the distance between the driven wheel 33 and the driving wheel 32 remains consistent, and there is no need to readjust the length or tension of the synchronous belt 34, thereby increasing the versatility of the handwheel remote control device.
