Abstract

The invention relates to an intelligent passive hemispherical directional automatic fire extinguishing device, and belongs to the technical field of fire-fighting fire extinguishing machinery. The intelligent passive hemispherical directional automatic fire extinguishing device comprises a hemispherical metal shell, a central control processor, a gas generator and a dry powder fire extinguishing agent. A plurality of spraying devices are uniformly arranged on the hemispherical surface, an intelligent detection alarm is installed between the spraying devices, the angle of the spraying devices can be freely adjusted, and the intelligent detection alarm is used for front-end detection and intelligent alarm. The control processor is fixed at the center of the hemisphere and is connected with an intelligent detection alarm, the spraying devices and the gas generator. The gas generator is installed at the hemispherical center. The hemispherical shell is filled with the dry powder extinguishing agent, and the dry powder extinguishing agent is isolated from a gas generating agent. After the intelligent alarm transmits a fire signal to the control processor and gives an alarm, the control processor controls the moving angle of the spraying devices, triggers an electric ignition head to ignite the gas generating agent, the ultra-fine dry powder fire extinguishing agent is sprayed out, and the fire is directionally extinguished in a totally submerged manner, so that fire extinguishing efficiency is high, and fire extinguishing efficiency is good.

Description

technical field

[0001] The invention relates to a fire-fighting equipment, in particular to an intelligent passive directional automatic fire-extinguishing device using a gas generating agent to a dry-powder fire-extinguishing agent, and belongs to the technical field of fire-fighting machinery. Background technique

[0002] At present, fires frequently occur in fixed spaces, such as housing construction, automobile (fire) car compartments, electric vehicle battery compartments, electrical cabinets, ship cabins, etc., with many ignition points, a wide range of ignition, and a large number of people involved in the disaster. The traditional water gun type fire extinguishing and spraying dry powder fire extinguishing are both man-made mobile fire extinguishing equipment, which need to be moved to the fire extinguishing site when in use. In order to ensure the fire extinguishing effect, the operator must be close to the fire source when using it. For narrow and crowded confined ...

Examples

Embodiment approach

[0033]The intelligent detection alarm has the functions of fire monitoring and linkage alarm, and is composed of a front-end sensor group and an intelligent alarm 12 . It mainly has the following two implementation methods: The first method is intelligent alarm: when a fire occurs, the front-end sensor group detects the fire, touches the intelligent alarm, and the alarm immediately emits a sharp sound, and at the same time through WIFI signals, satellite signals, etc. The wireless signal sends a warning to the fire monitoring department such as the fire control center, which is convenient for the staff to deal with it in time. The second way is intelligent information transmission: when the detection system detects that the fire exceeds the preset fire critical value, it immediately transmits the information to the control processor 6, and the control processor 6 directly controls the injection device in this direction to emit dry powder to extinguish the fire agent to realize...
