AI Technical Summary
The existing automatic fire monitor's limit device has a dead angle of rotation, which leads to problems such as cable entanglement and inaccurate operation.
By employing a worm gear transmission mechanism and a limit mechanism, combined with servo motor control, the fire monitor achieves 360° rotation self-locking and angle limitation. The worm gear controls the rotation of the worm wheel, and the design of the limit drive block and limit adjustment block avoids dead angles of rotation.
It enables precise adjustment and self-locking of the fire monitor, avoids cable entanglement, ensures stable angle of the fire monitor under high pressure, and improves the safety and reliability of operation.
