A rotary self-propelled fire extinguishing nozzle

Abstract

The invention relates to a rotary self-propelled fire extinguishing head comprising a rotary sleeve, a swiveling cover, a fixed cove, an end cover, a screw rod, a guide bar, a driveshaft, a regulating rod, a fixing sleeve, a swiveling shaft, a guide holder and a water supply jacket. The middle of the swiveling shaft is provided with an arc-shaped convex block and the right end of the swiveling shaft is provided with a laddered water inlet; a left inclined hole is formed in the left end of the laddered water inlet; the guide holder is provided with an arc-shaped slot; a right inclined hole is formed in the left end of the water supply jacket; the left end of the water supply jacket is provided with a circular-truncated-cone-shaped seat and the right end of the water supply jacket is provided with a gate slot; the two ends of the gate slot are provided with location blocks and a semi-annular plate is arranged inside the gate slot. The arc-shaped slot, the arc-shaped convex block and the circular-truncated-cone-shaped seat can be favorite to guarantee of the rotation speed and the overall advance distance of the rotary sleeve. In addition, the function that an extinguishing head can propel while rotating can be realized, and the problem that a rescue operator can not close to the fire center for performing fire extinguish in a fire spot is effectively solved.

AI Technical Summary

Problems solved by technology

However, the fire extinguishing nozzles on the existing market do not have the function of feeding while rotating, which cannot effectively solve the problem that rescuers cannot approach the fire source center of the fire scene to extinguish the fire. Some fire extinguishing nozzles lack the ability to improve the flow direction of the fluid and reduce the fluid energy. Lost device, which is not conducive to ensuring the rotation speed of the rotating sleeve and the overall forward distance, and some fire extinguishing nozzles lack the device to realize the adjustment function of the overall forward speed, which is not conducive to the control of the overall forward speed by firefighters
