Multifunctional firefighting lance

Abstract

The invention relates to a multifunctional firefighting lance. The multifunctional firefighting lance is characterized in that a detachable lance nozzle is arranged at the front end of a main firefighting pipe, wherein a handle is fixedly connected to the bottom part of the front end of the main firefighting pipe. The multifunctional firefighting lance further comprises an air gun pipe which is parallel to the main firefighting pipe, and a supporting column; the main firefighting pipe and the air gun pipe are reinforced and connected through the supporting column; a pressurizing pipe is arranged between the main firefighting pipe and the air gun pipe; a valve capable of adjusting water flow is arranged on the side surface of the tail end of the main firefighting pipe; the front end of the air gun pipe is sealed, and a flow valve capable of adjusting air flow is arranged on the top part of the tail end of the air gun pipe; the inner side of the air gun pipe communicates with the main firefighting pipe through the pressurizing pipe, and the input end of the pressurizing pipe is positioned between the flow valve and the front end of the air gun pipe; an one-way air valve for resisting water to enter the air gun pipe is arranged in the pressurizing pipe; a choke preventing mask is connected to the upper part of the air gun pipe through an air pipeline; a pressure reduction device is arranged in the air pipeline between the choke preventing mask and the air gun pipe. According to the multifunctional firefighting lance, the air pressurizing can be performed on the lance; dense smoke on the face of a firefighter can be dispersed through the choke preventing mask, so that the fire condition can be obviously observed, and the firefighter can be prevented from choking.
