The upper end of buoy body (1-1) is equipped with bearing (1-2), is used to settle fire extinguisher monomer (2), and the lower end of buoy body (1-1) is equipped with base (1-3), is used for not propping up on the ground when assembling buoy or oil tank have oil; The side of buoy body (1-1) is equipped with socket (1-4), is connected with pole (1-5) in the socket (1-4).When pole (1-5) only has a buoy (1) in fire extinguishing system, be used to make buoy (1) in jar, radially to locate; When fire extinguishing system adopts a plurality of buoy, be used for connecting with adjacent buoy.
Fire extinguisher monomer (2) is this fire extinguishing system can be implemented autonomous fire extinguishing in oil tank a core component.It can directly be chosen from the eruption type heavy dry-chemical fire extinguisher product line of registering patent of invention according to tank diameter size and total arrangement needs.Fire extinguisher monomer (2) can be placed on the buoy (1), also capable of hoisting hanging on support (3) or the tank top, and they are respectively with (2-1), (2-2) and (2-3) expression on Fig. 1.
When using on buoy, the lower end cap of fire extinguisher monomer (2-1) is inserted in the centre bore of bearing (1-2) of buoy (1), and is connected as a single entity by nut concentric float (1).
Hang when using, fire extinguisher monomer (2-2), (2-3) have by self hangs spiral shell and can directly hang on support (3) or tank top.
Support (3) is used to hang fire extinguisher monomer (2-2) and synchronous initiation device (4) is installed.According to the oil tank volume size, support (3) can connect into multiple geometry.Support (3) is combined by montant (3-1) and cross bar (3-2).According to buoy 91) difference of quantity, montant (3-1) can be connected on the pole (1-5), also can directly be connected on the buoy body (1-1).Cross bar (3-2) crossbearer is on corresponding hard bar (3-1).Cross bar (3-2) is used to hang fire extinguisher monomer (2-2) and synchronous initiation device (4) is installed.

When synchronous initiation device (4) is used for arranging fire extinguisher monomers (2) in a large number in large oil tank, guarantee all fire extinguisher monomers (2) of same aspect can be acted on simultaneously.It is made up of battery (4-1), temperature sensor (4-2), electric primer (4-3) and lead (4-4).Below all adopt the standard product.Battery (4-1) is used to synchronous initiation device (4) that the energy is provided; Temperature sensor (4-2) is used to control the effect opportunity of synchronous initiation device (4); Electric primer (4-3) is used to start fire extinguisher monomer (2).The three forms the closed-loop path by lead (4-4).Battery (4-1) and temperature sensor (4-2) can be placed on buoy (1), support (3) or the oil tank upper frame, and electric primer (4-3) places hanging in the spiral shell of corresponding fire extinguisher monomer (2) respectively.Electric primer (4-3) on the same aspect fire extinguisher monomer (2) connects together with battery on the corresponding aspect (4-1) and temperature sensor (4-2).Temperature sensor on the different aspects (4-2) is selected different operating temperature ranges for use.
Buoy of the present invention-the general structure of suspension comprehensive formula oil tank fire extinguishing system in oil tank should determine according to the size of oil storage tank diameter and two factors of height of selected fire extinguisher monomer (2) usefulness.Less when the oil storage tank diameter, only need when a center fire extinguisher monomer of placement (2) can guarantee to put out the pasta fire, then need not settle synchronous initiation device (4); When tank diameter is very big, on same aspect, have only when a plurality of fire extinguisher monomers (2) being set could guaranteeing effectively fire extinguishing, the then essential synchronous initiation device (4) of settling simultaneously, must fully be retained fire extinguishing range bridges district between each adjacent fire extinguisher monomer (2).
The mechanism of float-suspension dry powder fire-extinguishing system for oil tank of the present invention can be divided into two kinds of situations according to the difference of general structure.
When tank diameter less, fire extinguisher monomer (2) quantity seldom, thereby when synchronous initiation device (4) need be set, in the oil storage tank oil reservoir upper surface on fire after, at first the ignite following firing device of fire extinguisher monomer (2-1) of flame can put out flame by the effect of fire extinguisher monomer (2-1); If the misfire situation appears in the following firing device of fire extinguisher monomer (2-1), then behind 1 "～2 " that lag behind, flame promptly can be lighted the standby firing device of fire extinguisher monomer (2-1) top, starting fire extinguisher monomer (2-1), thus flame is put out.Because go up the flame temperature difference at various height, and the spontaneous ignition temperature difference of different aspects firing device, therefore, when lower floor's fire extinguisher monomer (2-1) was lighted, the fire extinguisher monomer (2-1) on adjacent upper strata can not lighted simultaneously.If after the first time, flame put out because surplus temperature or External Heat Flux and very fast appearances caught fire for the second time, then when flame reach a certain height with temperature after, the upper strata fire extinguisher monomer (2-2) or (2-3) of promptly igniting, thus back flame is put out.
When tank diameter is very big, fire extinguisher monomer (2) configuration quantity is more, thereby when synchronous initiation device (4) must be set, in the oil storage tank oil reservoir upper surface on fire after, the temperature on fluid top layer raises.After temperature was elevated to certain numerical value, the temperature sensor (4-2) in the synchronous initiation device (4) made battery (4-1) and electric primer (4-3) constitute the loop, and loop current is got angry electric primer (4-3), thereby fire extinguisher monomer (2) is had an effect.If the misfire situation appears in the electric primer (4-3) of certain fire extinguisher monomer (2), then behind sluggish 1 "～2 ", flame can ignite the standby firing device of this fire extinguisher monomer (2) below, replenishes starting fire extinguisher monomer (2), thus the situation in the dead band of having avoided occurring putting out a fire.Because the temperature sensor (4-2) in each layer synchronous initiation device (4) is to the sensitive range difference of temperature, thereby the situation that the fire extinguisher monomer (2) of different levels acts on simultaneously can not appear.If after the first time, flame put out, because surplus temperature or External Heat Flux and very fast appearances caught fire the second time, then after flame reaches uniform temperature, the synchronous initiation device (4) of second aspect begins effect, light second layer fire extinguisher monomer (2), thereby, back flame is put out.
