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

[0048] like Figure 1-2 As shown, a fire alarm and area fire extinguishing device includes: a first casing 1 , a second casing 2 , a third casing 3 , a transmission assembly 4 , a water outlet pipe 5 , a cylindrical cam 6 , and a water inlet pipe 7 .

[0049] Pipes 11 are horizontally arranged on the vertical wall surface of the first housing 1. The number of the pipes 11 is four. The four pipes 11 are arranged in four directions along the east, west, northwest, and temperature sensors 12 are respectively arranged in the four pipes 11. image 3 As shown, the four temperature sensors 12 divide the room into four areas for detection, the center of the first housing 1 is provided with a smoke sensor 13, and the temperature changes in the four indoor areas are detected by the four temperature sensors 12, that is, four Whether the temperature sensor 12 is triggered by the high temperature in the four areas, and then detects the indoor smoke through the smoke sensor 13 to determine ...

Abstract

The present invention relates to the technical field of fire detection, in particular to a fire alarm and area fire extinguishing device, comprising: a first casing, a second casing, a third casing, a transmission assembly, a water outlet pipe, a cylindrical cam, and a water inlet pipe; the present invention When a fire breaks out in the room, use four temperature sensors to locate the fire place, use the smoke sensor to determine whether there is a fire in the room, and then the motor drives the third housing to rotate to the fire place, the outlet pipe is discharged into the room, and the motor reverse Rotate, the cylindrical cam reverses, let the connecting rod flip up and down reciprocally, and extinguish the fire area, so as to realize regional fire extinguishment in the room, so as to avoid the existing fire extinguishing nozzles from raining the whole room to extinguish the fire, and the fire extinguishing efficiency is low.

Description

technical field [0001] The invention relates to the technical field of fire detection, in particular to a fire alarm and a regional 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, through which fire alarm devices can be used to detect indoor fires. , and then use fire extinguishing nozzles to extinguish the fire to avoid casualties and reduce property losses. However, the existing technology has shortcomings: at present, the fire alarm device cannot make a judgment on the source of the fire, and the sprinkler is not targeted. Once the alarm is triggered, the fire extinguishing nozzle will dewater the entire room and extinguish the fire due to the small water pressure. The fire extinguishing area of ​​the sprinkler is small, so the fire ext...
