Description
Technical field
The utility model belongs to technical field of fire control, is fixed on more particularly to one kind narrow inside new energy electric car battery case
The extinguishing device in small space.
Background technology
New energy（Pure electric vehicle or hybrid power）There is high-pressure power accumulator on Passenger Vehicle, power train in vehicle application accumulator is all
It is that several small battery cells are grouped into big Battery case according to certain use demand.
Lithium battery is different with other types battery, is very different in terms of electrode material, a most apparent feature
It is exactly that much more active than the electrode material of the batteries such as ni-mh, ni-Cd of the electrode material of lithium battery, this is also that lithium battery performance is excellent
A main cause more, after electrode material is active, the charge reflection rate between electrode will faster, so it discharges
The various aspects of performance such as rate will be more outstanding, but its controllability can also be lower therewith, is exactly that we are right for popular
The control dynamics of lithium battery group will weaken therewith, then unexpected situation, which occurs, in it to greatly increase.
It should be noted that lithium battery heat, overcharge or the abuse conditions such as overdischarge stream, vibration, extruding under may lead
Shorter battery life is caused so that damage or even the events such as can catch fire, explode, therefore the safety problem of battery and electricity becomes newly
Energy car urgent problem to be solved.
Existing traditional fire extinguisher be not volume it is excessive be exactly storage with pressure, not only occupy substantial amounts of space, it is also necessary to
It is punched on babinet, influences the degree of protection of babinet.In use, inevitably influenced be subject to external environment, itself
There are it is serious the defects of.
The content of the invention
A kind of extinguishing device being fixed on inside new energy electric car battery case provided by the utility model, it is flammable with detecting
Gas, fire extinguishing and datonation-inhibition function.
In order to solve the above technical problems, technical solution is used by the utility model：One kind is fixed on new energy electric car
Extinguishing device inside battery case including housing, is mounted therein with cylindrantherae, partition plate is equipped at the spray-hole of cylindrantherae, by housing
It is divided into two parts, is closed space by cylindrantherae one side, the housing of opposite side is equipped with squit hole, face and partition plate where squit hole
Vertically；Through hole is offered on partition plate, the spray-hole of cylindrantherae is connected by through hole with housing opposite side.
Further, it is additionally provided with gas detector in closed space.It is arranged on the rear of cylindrantherae
Further, which further includes fixed seat, and cylindrantherae is fixed on by fixed seat in housing.
Further, the housing is rectangular-shape, and partition plate is parallel with the end plate at its both ends.
Further, cylindrantherae is connected with startup line, starts line and is pierced by connection controller from closed space, starts and is installed outside line
There is protective case.Extinguishing medium propellant is housed inside cylindrantherae.
The invention has the advantages that：
1st, the utility model compact saves installation space, and fire extinguishing is rapid, and fire extinguishing inhibits secondary combustion in battery case simultaneously
It burns.
2nd, the utility model has the function of combustible gas detecting, and cooperation line-type heat detector can accurately more ensure battery
The security of case.Line-type heat detector is arranged in battery case around battery module.
3rd, the particle that the utility model cylindrantherae spray-hole sprays first is turned to through housing end plate and adsorbed not complete in course of injection
The useless extinguishing material of the bulky grain that decomposes entirely can realize that the flow direction of monotubular extinguishing material turns to.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model, but the scope of the requires of the utility model protection are further illustrated with reference to embodiment and attached drawing
It is not limited to the scope of embodiment statement.
As shown in Figure 1, a kind of extinguishing device being fixed on inside new energy electric car battery case, including housing 1, interior installation
There is cylindrantherae 2, be equipped with partition plate 3 at the spray-hole of cylindrantherae, housing is divided into two parts, be closed space by cylindrantherae one side, separately
The housing of one side is equipped with squit hole 4, face and divider upright where squit hole；Through hole 5, the spray-hole of cylindrantherae are offered on partition plate
It is connected by through hole with housing opposite side.
Further, gas detector 6 is additionally provided in closed space.It is mounted on away from the one side of cylindrantherae spray-hole.Gas
Whether battery modules breakage, the fuel gas that volatilizes are had in bulk detector monitoring cell case.It can grasp at the first time in battery
Portion's situation.
Further, which further includes fixed seat 7, and cylindrantherae is fixed on by fixed seat in housing.Fixed seat in Fig. 1
To be divided into two parts, a part is welded with housing upper, and another part is welded with lower housing portion, and cylindrantherae is installed between the two sections
It is fixed, prevents its movement, it is ensured that the fixing of its structure.
Further, the housing is rectangular-shape, and partition plate is parallel with the end plate at its both ends.
Further, the startup line of cylindrantherae is pierced by connection controller from closed space, starts line 8 to be equipped with protective case.
Ensure that circuit will not wear-out failure during installation and use.
Fig. 1 middle casings are made of upper and lower two parts, set partition plate that housing is divided into two parts, the particle meeting that cylindrantherae ejects
Reach on the end plate of shell end, then turned to by its water conservancy diversion, and adsorb spurt during the bulky grain that does not decompose completely without
Extinguishing material.
When lithium battery heat, overcharge or the abuse conditions such as overdischarge stream, vibration, extruding under battery life may be caused to contract
It is short so that damage or even can catch fire, explode when events, the extinguishing device of the utility model coordinates line-type heat detector
Rapid detection fire behavior, signal pass to controller, and controller provides enabling signal, rapid to implement fire extinguishing, success in first time
It puts out a fire and inhibits second-time burning and explosion, loss is preferably minimized, greatly strengthens the security of battery case, so as to prevent
Cause uncontrollable fire due to battery case catches fire, avoid major accident.
