Problems solved by technology

However, there are deficiencies in the existing technology: at present, the fire alarm device cannot make a judgment on the fire source, and the water sprinkling is not targeted. Once the alarm is triggered, the fire extinguishing nozzle will rain down the entire room to extinguish the fire, and it is affected by the small water pressure. The fire extinguishing area of ​​the nozzle is small, so the fire extinguishing efficiency is low. In order to improve the fire extinguishing efficiency, it is often necessary to install multiple fire extinguishing nozzles in a room. The layout and construction of the pipeline are very difficult, resulting in high cost

Abstract

The invention relates to the technical field of fire detection, in particular to a fire alarm and regional fire extinguishing device which comprises a first shell, a second shell, a third shell, a transmission assembly, a water outlet pipe, a columnar cam and a water inlet pipe. When a fire occurs indoors, the fire is positioned through four temperature sensors, whether the fire occurs indoors or not is determined through a smoke sensor, then a motor drives the third shell to rotate to the fire, the water outlet pipe discharges water into a room, the motor rotates reversely, a columnar cam rotates reversely, a connecting rod is overturned up and down in a reciprocating mode, fire extinguishing is conducted on a fire area, regional fire extinguishing is conducted indoors, and therefore the situation that an existing fire extinguishing nozzle conducts water falling fire extinguishing on the whole room, and the fire extinguishing efficiency is low is avoided.

Description

technical field [0001] The invention relates to the technical field of fire detection, in particular to a fire alarm and area fire extinguishing device. Background technique [0002] Fire is one of the disasters that generally threaten human safety. In order to prevent the occurrence of fire, more and more places, such as public meeting rooms, hotels and other places, have begun to install fire alarm devices, which can detect indoor fires. , and then extinguish the fire through the fire extinguishing nozzle to avoid casualties and reduce property losses. However, there are deficiencies in the existing technology: at present, the fire alarm device cannot make a judgment on the fire source, and the water sprinkling is not targeted. Once the alarm is triggered, the fire extinguishing nozzle will carry out precipitation to extinguish the fire in the entire room, and is affected by the small water pressure. The fire extinguishing area of ​​the nozzle is small, thereby the fire e...
