Meanwhile, the fire information and the position information of the ignition point can be synchronously transmitted out through a bus technology, and more accurate information is provided for safe evacuation of people and early fire extinguishment through manual intervention. Therefore, the fire protection effect is obvious, and the social significance is great.
The utility model discloses technical scheme as follows:
the utility model provides a water outlet sealing member is set up in the activity of the delivery port department of fire control of shower nozzle main part, delivery port sealing member and the spheroidal top swing joint of glass, the spheroidal bottom of glass and the spheroidal top swing joint of electrical heating glass, the spheroidal bottom of electrical heating glass and the bottom swing joint of shower nozzle main part.
The glass ball body is movably connected with the electric heating glass ball body through a sliding block.
The glass ball body and the electric heating glass ball body are two independent cavity glass ball bodies, and the electric heating glass ball body is provided with an electric heating wire.
The glass ball body and the electric heating glass ball body are filled with liquid with high thermal expansion coefficient.
The electric heating wire is connected with the detection control unit through a lead.
The detection control unit comprises a fire collector, an analysis control circuit and a communication bus circuit.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the automatic and quick fixed-point water spraying fire extinguishing device is added with the function of actively analyzing and detecting the fire source by the spray header, and can realize automatic and quick fixed-point water spraying fire extinguishing.
2. The detection control unit enables the spray header to have the functions of remote transmission and networking of fire information, and provides a technical basis for centralized management and control of the fire information.
3. The active detection technology wins time for people evacuation, realizes early fire extinguishing, and greatly improves the probability of extinguishing fire.
