Abstract
The invention discloses a flow-adjustable fire-fighting cannon head with a supercavitation technology. The flow-adjustable fire-fighting cannon head comprises a cannon head body, a water outlet adjusting stop block and a mandrel. An opening in the upper end of the cannon head body is a water outlet. The water outlet adjusting stop block is suspended in the water outlet of the cannon head body. The mandrel penetrates the axis of the water outlet adjusting stop block. The lower end of the mandrel is fixed in the cannon head body. The upper end of the mandrel penetrates the water outlet adjusting stop block and is fixedly connected with a water cannon core. A spiral sliding groove is machined in the outer circumferential face of the water cannon core. One end of the sliding groove extends downwards to penetrate the lower end face of the water cannon core to form a release groove. The other end of the sliding groove is bent upwards to form a clamping and stopping groove. The upper side wall of the sliding groove is concaved downwards to form a plurality of gear grooves. A blind hole used for installing the water cannon core is formed in the upper portion of the water outlet adjusting stop block along the axis. A pin shaft is arranged on the side wall of the blind hole. The pin shaft enters the sliding groove from the release groove, can slide along the sliding groove and is clamped and stopped through the gear grooves or the clamping and stopping groove. According to the flow-adjustable fire-fighting cannon head, multiple gears adjusting the water outlet flow are arranged, and water conservation is achieved.
