Indoor large-space automatic fire extinguishing device capable of seeking target in short time

Abstract

The invention discloses an indoor large-space automatic fire extinguishing device capable of seeking a target in short time, comprising a bottom plate, a shell I, a water inlet pipe, a connecting water pipe, a big horizontal gear, a bent connecting pipe, a pitching motor, a shell II, a small pitching gear, a bent water outlet pipe, a spray nozzle, a pitching detector, a horizontal detector, a movable cover, a screw rod, a big pitching gear, a screw gear, a small horizontal gear and a horizontal motor. After the fire source is detected by the horizontal detector, the horizontal motor is started to drive the screw rod to rotate through a horizontal driving mechanism so as to make the movable cover move and shield the detection scope of the horizontal detector, and the fire source is positioned horizontally. The pitching motor drives the pitching detector which is fixed on the spray nozzle to swing vertically through driving gear so as to determine the vertical position of the fire source and drive the spray nozzle to spray actively. The indoor large-space automatic fire extinguishing device can accurately position the fire source space, and the auxiliary mechanical positioning device can rapidly seek the target in short time, thus the fire extinguishing efficiency is improved. The indoor large-space automatic fire extinguishing device is suitable for the indoor large-space building.

Description

technical field [0001] The invention relates to an indoor large space fire extinguishing device, in particular to an indoor large space automatic fire extinguishing device which can shorten the search time. Background technique [0002] The detection and suppression of early fires in indoor large space buildings has always been an international problem. Due to the special structure and function of indoor large space buildings, its fire protection is different from conventional buildings. With the rapid development of large-space buildings, their fire protection problems have become increasingly prominent. [0003] Most of the existing indoor large space fire extinguishing devices are sprinkler systems and fire water cannons. The equipment of the automatic sprinkler system is relatively complicated, and the fixed sprinkler head does not have the function of searching for the location of the fire. When the sprinkler is started, the fire is already large, and the sprinkler ca...

Problems solved by technology

The positioning of the fire water cannon is also completed under the remote control of people, so it is not convenient to use in unattended places

The existing domestic small-scale intelligent fire water cannon fire extinguishing system can also automatically identify the flame and locate the fire, but the system uses many detectors, generally 4 to 8, the overall cost of the system is relatively high, and the control is complicated; The time is relatively long, which affects the fire extinguishing efficiency
