Description
Technical field
The invention belongs to fire prevention field, particularly relate to the one generating self-starting device that is heated.
Background technology
Along with the raising of people to security against fire understanding, the quantity that extinguishing device uses is more and more, therefore the safety to extinguishing device, reliability also more and more receive people's concern, in existing aerosol and reservoir pressure, non-reservoir pressure ultrafine dry powder extinguishing installation, the Starting mode of these extinguishing devices mainly contains following two kinds:
One is to start with heat-sensitive line; heat-sensitive line is the linear structure of being made and being connected with extinguishing device by temperature-sensitive pyrophoric material; in the time of breaking out of fire, the heat-sensitive line that is positioned at protection zone by spontaneous combustion, utilizes the heat that spontaneous combustion produces to start extinguishing device in the time reaching uniform temperature.The shortcoming of this Starting mode be after heat-sensitive line makes moist or be subject to external force to do the used time easily broken, at this moment cannot detect fire.On the other hand, in fact heat-sensitive line is exactly a kind of fuse cord, belongs to inflammable and explosive dangerous goods, needs the special industry license of public security department in storage, transportation and use, and therefore potential safety hazard is larger.
Another kind is to start with electrothermal method, as the electric initiator in the industry standards of public safety GA499.1-2004 of the People's Republic of China (PRC) " GAFES ", it is by being heat energy by electric energy conversion, make extinguishing chemical or burning medicament burning, so produce expand and outwards the mode of spraying fire-extinguishing agent start extinguishing device.General aerosol fire-extinguishing device is exactly that profit starts in this way.This Starting mode is used fire-fighting power supply or powered battery conventionally, shortcoming is that the electrical interconnection between fire-fighting power supply and battery and extinguishing device is longer, once power line occurs that open circuit fault or battery are without electric situation, owing to there is no power supply, therefore electric initiator cannot start.
As described in ISBN7-118-03740-0 " thermal cell " book of writing as Lu Ruisheng, Liu Xiaojiang, thermal cell is that one is made electrolytical hot activation reserve cell with fused salt, when storage, molten salt electrolyte is nonconducting solid state salt electrolyte, when use, by the ignite heating medicament of its inside of power supply or shock, make solid-state molten salt electrolyte heating and melting become the ionic conductor of conduction and enter duty.
Using fused salt class electrolyte is the principal character of thermal cell, due to the electrolytelike use of fused salt, after must making it be melt into ionic conductor the heating of fused salt class electrolyte, just can make battery activated electric discharge, again because fused salt class electrolyte is nonconducting solid below melting temperature, battery self discharge in storage process is very little, is convenient to long term storage.
Conventional thermal cell mainly consists of the following components at present:
1, positive pole: the sheet-like structure mainly being formed by positive active material and substrate.Conventional positive active material has: ferrous disulfide, tungstic acid, vanadic anhydride, plumbous chromate, potassium bichromate etc.
2, negative pole: the sheet-like structure mainly being formed by negative electrode active material and substrate.Conventional negative electrode active material has: magnesium, calcium, lithium-aluminium alloy, lithium silicon alloy etc.
3, molten salt electrolyte (or barrier film): as electrolytical sheet-like structure, mainly formed by salt electrolyte and adhesive in battery, except plaing ionic conduction effect, also can stop the electronic conduction between positive plate and negative plate.
4, heating system: accept ignition signal and ignite to make thermal cell internal temperature rise to a set of parts of operating temperature, mainly formed by electric igniter (when electricity activates) or igniter cap (when mechanical activation), Kindling paper and heating plate.
5, insulating pad: being made up of asbestos, mica sheet, ceramic fibre etc., is the various pads with function of heat insulation.
6, battery case: the container of contained structure part.
Fig. 1 is a kind of existing thermal cell structural representation; As shown in Figure 1, this thermal cell comprises positive pole 11, molten salt electrolyte 12, negative pole 13, heating plate 14, output wiring terminal 15, case lid 16, housing 17, activation block 18 and heat-insulation layer 19; The medial surface of its middle shell 17 is provided with heat-insulation layer 19; In heat-insulation layer 19, be provided with successively from bottom to up heating plate 14, negative pole 13, molten salt electrolyte 12 and anodal 11; Case lid 16 covers the upper port place of housing 17, and the lower end which is provided with 15, two output wiring terminals 15 of two output wiring terminals is electrically connected with anodal 11 and negative pole 13 respectively; Activation block 18 is arranged on the outside, bottom surface of housing 17.
Under normal circumstances, because molten salt electrolyte 12 is solid state at normal temperatures, output wiring terminal 15 does not have voltage.In the time having external force collision activation block 18, activation block 18 release heat, this heat will be passed to heating plate 14 by housing 17, thus heating plate 14 is started, the heat that heating plate 14 discharges makes molten salt electrolyte 12 meltings, thereby make its be transformed from the solidified state into can ionic conduction liquid state, will there is oxidation reaction and lose electronics with molten salt electrolyte 12 in negative pole 13 at this moment; Anodal 11 there is reduction reaction and obtain electronics with molten salt electrolyte 12, thereby at output wiring terminal 15 two ends output voltages.The effect of heat-insulation layer 19 is the losses that reduce heat, so that thermal cell reaches the longer working time.
Because it has very high specific energy and specific power, environment for use temperature is wide, period of storage long, activate rapidly reliable, compact conformation, simple process, cheap, do not need the advantages such as maintenance, be subject to the favor of military circles once coming out, the ideal source that develops into the sophisticated weapons such as guided missile, nuclear weapon, cannon, occupies critical positions in military field.But be not yet applied at present fire protection sector.
