The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Because a lot of fire extinguisher, especially super-sonic dry-chemical fire extinguishers can produce certain recoil when action, thereby have influenced the application of super-sonic dry-chemical fire extinguisher, in order to enlarge application, the recoil problem when needing to solve the extinguishing device action.When the dry powder in the extinguishing device sprays, on the holder of extinguishing device, can be subjected to a power, be exactly that our said recoil acts on the holder, this power will damage holder when surpassing the intensity of holder, so wish that recoil is as much as possible little.
Fig. 1 is the structural representation of the utility model extinguishing device, and as shown in the figure, the utility model extinguishing device comprises housing 1 and buffer 2.
Again as shown in Figure 1, the utility model extinguishing device also comprises initiator 3, porous member 4 and baffle plate 5.
Initiator 3 is fixed on housing 1 bottom, and porous member 4 is fixed on housing 1 bottom and is contained in the housing 1, and initiator 3 is contained in the porous member 4; Baffle plate 5 is connected with housing 1, forms cavity.
Concrete, initiator 3 is fixed on top cover 10 central authorities by the central, threaded hole, and buffer 2 is fixed on the opposite side of top cover 10.Match with porous member 4 upper ends in the bottom of top cover 10, initiator 3, top cover 10 and porous member 4 these threes form an enclosure space in the inside of porous member 4, form gas generator jointly.Be furnished with some screwed holes, housing 1 lower end and baffle plate 5 sealing-ins around the top cover 10.
By the impulse conservation law theorem as can be known, a momentum of oriented certain direction exists, and must have individual momentum round about to exist, and the two is an equal and opposite in direction, and direction is opposite.When extinguishing device spurted, dry powder sprayed to the scene of a fire at a high speed, just had certain momentum mv (m represents dry powder quality, and v represents the dry powder movement velocity) to exist.Dui Ying momentum also exists with it, but this momentum acts on the extinguishing device, and extinguishing device can not move, and just this momentum is converted into recoil and acts on the supporter of extinguishing device, shows as Ft (F represents recoil, and t represents the duration of F).Here, Ft=mv.Under the certain situation of mv, t is big more, and then F is more little.In collision process, rigid collision, the time is the shortest, and the time of elastic collision is relatively long, thereby F is less relatively.So, prolong the recoil that t reduces extinguishing device by buffer 2.
After fire takes place, be installed in on-the-spot inductor and detect the condition of a fire, send a signal to controller, there had been fire at the judgement scene after controller received signal, just send enabling signal and give extinguishing device, after device received enabling signal, initiator 3 at first started, and formed high temperature, gases at high pressure in the combustion chamber being made up of top cover 10, porous member 4 fast.A part forms high velocity air by the spray orifice on the porous member 4 then and impacts extinguishing chemical dry powder 6, makes it disturbance, fragmentation, atomizing.When housing 1 internal pressure enough was enough to greatly break through the restriction of baffle plate 5, extinguishing chemical dry powder was just gone out extinguishing device, rushes at the scene of a fire, stamps out the flames, and finishes fire-extinguishing function concurrently.
In the process that dry powder spurts, dry powder has momentum forward, and extinguishing device has a momentum opposite with dry powder momentum direction, these two momentum equal and opposite in directions, and direction is opposite.Because extinguishing device can not move, momentum is converted into shock loading, is delivered on the holder of extinguishing device.Have: Ft=mv, the existence of buffer, the recoil that makes extinguishing device produce is delivered on the buffer, buffer generation deformation, absorb a part of strength (strength that absorbs during buffer deformation, be released when deformation disappears, be delayed the action time of this part strength) and with the supporter of another part strength transmission to device; When elastic material deformation, prolong simultaneously the transformation time t of momentum, so directly reduced recoil.
This buffer can be the parts that have elasticity arbitrarily and can absorb recoil, for example, cushion pad, spring leaf or spring, cushion pad can be rubber blanket.
Cushion pad, spring leaf or the spring of forming buffer 2 have a variety of situations, for example cushion pad, spring leaf or spring are full wafer cushion pad, spring leaf or spring, referring to shown in Figure 2, having installing hole 20 on the buffer 2, perhaps is ring-type cushion pad, spring leaf or spring, as shown in Figure 3, perhaps a plurality of cushion pads, spring leaf or the spring of arranging for annular concentric, as shown in Figure 4, again or a plurality of cushion pads, spring leaf or the spring arranged, as shown in Figure 5.
Extinguishing device of the present invention has reduced extinguishing device by buffer is set, for example super-sonic dry-chemical fire extinguisher the action the time recoil, make that the application of super-sonic dry-chemical fire extinguisher is more extensive.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
