Electro-thermal detonation fast-response temperature-sensitive rotary spraying fire extinguishing apparatus

Abstract

The invention discloses an electro-thermal detonation fast-response temperature-sensitive rotary spraying fire extinguishing apparatus, comprising a water inlet pipe and a water nozzle body; the waternozzle body is composed of a water nozzle cap and a water nozzle, a water cavity is arranged in the water nozzle body and is communicated with the water inlet pipe, a group of wedgelike water outlets, which are deviated from a central line and are arrayed symmetrically, are arranged on the water nozzle, a water-stopping valve plug is arranged in the water nozzle body, a supporting bracket is arranged below the water nozzle, a temperature-sensitive glass bead device is arranged in the supporting bracket and comprises a temperature-sensitive glass bead and an electric heating wire, the upper end of the temperature-sensitive glass bead is contacted with the lower end of the water-stopping valve plug, the lower end of the temperature-sensitive glass bead is contacted with the supporting bracket, the electric heating wire is arranged on the temperature-sensitive glass bead and is connected with a power supply and a control switch. When fire alarm happens, the control switch acts on, the power supply is switched on, the electric heating wire is powered on to heat to leading the temperature-sensitive glass bead to reach the rated allowable temperature by acceleration, after the temperature of the temperature-sensitive glass bead reaches the rated allowable temperature, the temperature-sensitive glass bead is detonated, the detonated temperature-sensitive glass bead is bounded out from the supporting bracket, centrifugal force generated by the water nozzle body leads water which is sprayed out at high speed from the water outlets to be sprayed out in a parabolic shape, thereby achieving the effect of omnibearing water spraying and large-area fire extinguishment.

Description

technical field [0001] The invention relates to a sprinkler fire extinguishing device. Background technique [0002] CN200820045531.2 discloses a rotary temperature-sensitive sprinkler fire extinguishing device, the device includes a water inlet pipe and a faucet body, the faucet body is composed of a faucet cover and a faucet, the middle part of the faucet cover is provided with a through hole, the through hole The aperture of the water inlet pipe is equivalent to the diameter of the water inlet pipe. One end of the water inlet pipe is provided with a shoulder extending outward. The water inlet pipe is installed in the through hole of the faucet cover and connected with the faucet body. A ring-shaped gap is formed inside, and a group of balls are placed in the gap; there is a water chamber inside the faucet body, and the water chamber is connected with the water inlet pipe. The water cavity is connected; a water stop valve core is arranged in the body of the water nozzle, ...

AI Technical Summary

Problems solved by technology

[0003] But above-mentioned device may exist the time-delay bursting of glass temperature sensing element in actual use and thus delay the defective of sprinkler fire extinguishing, this is because when breaking out of fire, because fire source usually has a certain distance from sprinkler fire extinguishing device, just fire source and There is a certain distance between the glass temperature sensing element, and it takes a period of time for the temperature of the glass temperature sensing element to reach its rated allowable temperature, and the delay for this period of time may have serious consequences for the fire alarm, so a rapid response burst is provided. The temperature-sensitive glass element is particularly important
