Abstract

The utility model discloses a rotary injection automatic fire extinguishing machine which can arranged in the center position of a fire district. A temperature sensing control circuit can be switched on by a mercury switch to cause high pressure gas generated by the detonation of an electric detonating thrust bomb to push piston motion. A push rod connected with a piston can be pushed to open a valve. An extinguishing agent can be injected into an injection disc from a storage tank via the valve and a hollow shaft. Three injection openings, every two of which mutually form an angle of 120 DEG and the injection disc can be injected in tangential direction. The utility model has the characteristics of timely and automatic start, large injection area in unit time, and fire extinction in the center position of a fire scene. The extinguishing agent can be evenly injected in a rotary mode.

Description

The rotary-jet automatic fire sprinkler

The utility model provides a kind of can start the spray that the rotary-jet extinguishing chemical is put out a fire automatically when fire takes place.

At present, the hand-held spray that use in the fire prevention place is by manually putting out a fire with hand operated, when occurring to, the condition of a fire it is found that the condition of a fire takes the fire extinguishing of this hand-held spray, delay time at stop often, the intensity of a fire is enlarged, and this spray to exist the area of spray fire extinguishing agent in the unit interval little and inhomogeneous and because of manually-operated can only fire extinguishing can not be in deficiencies such as flame kernel position uses in marginal zone, the scene of a fire.

The automatic fire sprinkler that the utility model provides a kind of and is arranged at the fire district centre, can in time start automatically when the condition of a fire takes place, large tracts of land Rotating with Uniform spray fire extinguishing agent is put out a fire in the unit interval.

The purpose of this utility model is that following mode is finished:

Mercoid switch [2] bottom mercury is connected by lead and battery [1] are anodal, two lead-in wires of electric initiating thrust bullet [5] are connected with electrode [3] with battery [1] negative pole respectively, piston [6] in the plunger shaft [7] is connected with push rod [8], push rod [8] other end withstands valve [9], and self-locking spring [10] promotes self-lock pin [11].Can insert self-locking grooves [12] when travelling forward in that push rod is stressed, valve [9] communicates with hollow shaft [15], injection dish [16], jet [17].Injection dish [16] and hollow shaft [15] combination can pivot when extinguishing chemical sprays.

This spray is compared with manual spray, has in time, starting automatically, and the rotary-jet extinguishing chemical is even, projected area is big and can be in the characteristics of body of fire position fire extinguishing in the unit interval.

Below in conjunction with accompanying drawing utility model is further described.

Fig. 1 is the structural representation of utility model;

Fig. 2 is the vertical view of rotary-jet dish.

Known by Fig. 1: mercoid switch [2] bottom mercury is connected by lead and battery [1] are anodal, two lead-in wires of electric initiating thrust bullet [5] are connected with electrode [3] with battery [1] negative pole respectively, when circuit is connected, electric initiating thrust bullet produces gases at high pressure promotion pistons [6] and travels forward, piston [6] in the plunger shaft [7] is connected with push rod [8], push rod [8] other end withstands valve [9], self-locking spring [10] promotes self-lock pin [11], when stressed the travelling forward of push rod [8], can insert self-locking grooves [12], valve [9] and hollow shaft [15], jet [17] communicates, at valve [9] when opening, extinguishing chemical [14] can be injected injection dish [16] through hollow shaft [15], spray through jet [17], the injection dish can pivot simultaneously.When the condition of a fire takes place, mercury expanded by heating volume in the mercoid switch [2] that joins with battery [1] positive pole increases along glass tube and rises and electrode [3] is connected, electric current detonates it through lead [4] by electric initiating thrust bullet [5], producing gases at high pressure promotion pistons [6] travels forward along plunger shaft [7], make the push rod [8] that links to each other with piston promote to open valve [9] forward, meanwhile, self-lock pin spring [10] promotes self-lock pin [11] and inserts self-locking grooves [12], make the push rod [8] can not resilience, guarantee that valve [9] is unimpeded, the unnecessary gas that thrust bullet [5] outburst back produces is discharged through steam vent [13].At this moment, high-pressure extinction agent [14] enters hollow shaft [15], injection dish [16] through valve [9], from rotary-jet dish [16] be tangential direction each other the jet of hexagonal angle [17] eject.Under the recoil strength effect of gases at high pressure extinguishing chemical, rotary-jet dish [16] is done rotation at a high speed, and the extinguishing chemical of ejection forms umbrella shoe capping and covers on the flame front, and air-isolation extinguishes the flame anoxic.

Claims

1 one kinds of rotary-jet automatic fire sprinklers, comprise mercoid switch, battery, lead, storage tank, extinguishing chemical is formed, it is characterized in that: mercoid switch [2] bottom mercury is connected by lead and battery [1] are anodal, two lead-in wires of electric initiating thrust bullet [5] are connected with electrode [3] with battery [1] negative pole respectively, piston [6] in the plunger shaft [7] is connected with push rod [8], the push rod other end withstands valve [9], self-locking spring [10] promotes self-lock pin [11], when stressed the travelling forward of push rod [8], can insert self-locking grooves [12], valve [9] and hollow shaft [15], injection dish [16], jet [17] communicates.

2 rotary-jet automatic fire sprinklers according to claim 1 is characterized in that injection dish [16] and hollow shaft [15] combination, can pivot when extinguishing chemical sprays.
