Description

Automatic fire extinguishing unit

The utility model relates to extinguishing device, particularly automatic gas fire extinguishing unit.

China is extensive use of no pipe network automatic gas extinguishing device at present, mostly adopt fusible alloy or glass marble temperature-sensitive element as fire extinguisher relieving mechanism and double as fire detector, the fire extinguisher more than 40 liters then adopts the gas delivery mode of pre-unlatching of magnetic valve and gas cylinder secondary opening in this way.These devices have following shortcoming:

1, fire detection is the one-parameter sampling, does not have the fire-alarm prediction function;

2, fusible alloy or the glass marble temperature-sensitive element as fire detection and fire extinguisher relieving mechanism all belongs to the qualitative selection of physical quantity, the inhorn characteristic of its material therefor and manufacture craft limit accuracy and the controllability that this parameter is selected, therefore, the probability that leaks action and misoperation is higher, like this, extinguishing chemical unnecessarily is released or incurs loss through delay best fire extinguishing constantly, cause unnecessary loss;

3, adopt more than 40 liters that magnetic valve is pre-to be opened and the fire extinguisher of gas cylinder secondary opening is applicable to space more than 100 cubic metres, can only adopt total flooding fire-fighting fire extinguishing mode, but to connect with controlling alarm, its project installation complexity, and want the leakage situation of running check gas cylinder, and in time fill high pressure gas, could guarantee the reliability of release movement, therefore more complicated bothers;

4, to produce contact few for signal, can not form network;

5, the fire extinguisher product function that has is simple, the processed complex of mechanical actuation device, could use after gas cylinder must be reequiped.

The purpose of this utility model is: a kind of automatic gas fire extinguishing unit is provided, and this fire extinguishing Elementary Function is complete, safe and reliable, flexible, and gas cylinder need not reequiped and can be used.

The purpose of this utility model reaches like this: this fire extinguishing unit has mainframe box, ion smoke detector, the electronic temperature sensing fire detector, single district single loop fire alarm control unit, alkyl halide fire extinguishing steel cylinder, by also having by helical pressure and movement guide mechanism, the gas cylinder handle, fastening and the height guiding mechanism in thermo-mechanical drive that gear reduction box is formed and steel cylinder bottom, said helical pressure and movement guide mechanism are by dust cap, regulating wheel, gland, screw rod, sliding nut, pressing plate, guide pin bushing and supporting tray are formed, the steel cylinder handle is positioned between supporting tray and the pressing plate, and gas bomb is fixed between bottom tray and the steel cylinder handle.In gear-box, be provided with driving gear and driven gear side by side, driving gear is coaxial with direct current generator, driven gear and screw coaxial, driving gear and driven gear are in same level, forming the face gear institutional level slows down, the guide pin bushing diametric(al) has " one " font gathering sill, this sliding nut section is a T shape, guide pin bushing is located on the gear-box, this sliding nut and pressing plate are fixed together and are embedded in the gathering sill of guide pin bushing, fastening and the height guiding mechanism in said fire extinguishing steel cylinder bottom is by nut, short screw, pallet, 2 of steady pins, moving pin and adjusting bolt are formed, the short screw that is fixed together with pallet and be in pallet downside central authorities with nut that frame is fixed together, pallet is positioned under the fire extinguishing steel cylinder, is provided with two steady pins and a moving pin on this pallet, and three pins are evenly distributed on the pallet.

Below in conjunction with accompanying drawing the utility model is elaborated.

Accompanying drawing 1 is this fire extinguishing unit front view;

Accompanying drawing 2 is enlarged drawings of thermo-mechanical drive in the accompanying drawing 1;

Accompanying drawing 3 is thermo-mechanical drive schematic diagrams;

Accompanying drawing 4 is bottom views of this fire extinguisher steel cylinder bottom;
