At this time, it should be noted that a certain length of hose needs to be reserved so that the fire water monitor main body 8 can stably supply water when rotating. When adjusting the horizontal angle of the fire water monitor main body 8, first start the lifting motor 14 to drive the threaded rod 15 to rotate, thereby driving the transmission block 13 to descend, and then making the lifting frame 10 and the internal gear ring 11 descend to disengage from the gear 5. At this time, the servo motor 3 can be started to drive the rotating shaft 4 to rotate, thereby driving the rotating disk 6 and the fire water monitor main body 8 to rotate, so that the servo motor 3 can drive the fire water monitor main body 8 to rotate horizontally by 360 degrees. After the horizontal angle adjustment of the fire water monitor main body 8 is completed, the lifting motor 14 can be started again to raise the lifting frame 10 to the maximum position. At this time, engage the internal gear ring 11 with the gear 5. At this time, the stabilizing block 21 on the lifting frame 10 can only slide within the stabilizing groove 20, and the transmission block 13 can only slide within the transmission groove 12, thereby restricting the rotation of the lifting frame 10, and further making the internal gear ring 11 unable to rotate, thereby restricting the gear 5 from rotating, and further positioning the rotating shaft 4, and then positioning the rotating disk 6, avoiding the situation that the rotating disk 6 rotates during the spraying process of the fire water monitor main body 8. When adjusting the tilt angle of the fire water monitor main body 8, only need to start the electric telescopic rod 17. When the electric telescopic rod 17 retracts, the fire water monitor main body 8 tilts downward, and vice versa upward.
