Description
Technical field
The utility model is related to fire-extinguishing apparatus technical field, specifically new energy car battery case extinguishing device.
Background technology
Automobile is modern the most widely used transport facility, plays highly important angle in modern society
Color, however the problems such as orthodox car brings environmental pollution, climate warming and the energy crisis of getting worse, using free of contamination electricity
Electrical automobile becomes the prior development direction of major Automobile Enterprises.In order to ensure height of the on-vehicle battery under different extraneous operating temperatures
Efficiency, the research of battery case are more and more.Due to accident fire may occur for the on-vehicle battery in battery case, easily draw
The accident of rising.Therefore design new energy car battery case extinguishing device is damaged for eliminating automobile fire, reduction personal injury and property
Mistake all has a very important significance.
Therefore, it is proposed that new energy car battery case extinguishing device, the device prevent to ensure the security performance of automobile
Using the temperature inside temperature sensor monitors battery case, extinguishing device is controlled by controller for the generation of battery case fire
Two kinds of fire-fighting modes of extinction using gas and dry-chemical fire extinguishing are combined and can have the fire inside battery case by work, the extinguishing device
In the elimination of effect stage in the early stage, prevent the expansion of fire incident.
The Chinese patent literature of 203253085 U of open (bulletin) number CN discloses a kind of battery case extinguishing device, is used for
Electric vehicle, including temperature-sensitive automatic detection device, extinguishing device and the reception being arranged on inside the battery case of the electric vehicle
The signal of the temperature-sensitive automatic detection device controls the controller of the extinguishing device work, and the extinguishing device includes fire extinguishing
Device, fire extinction pipeline and the fire extinguishing sprayer being arranged on the fire extinction pipeline, fire extinction pipeline are three, on every fire extinction pipeline
It sets there are two the fire extinguishing sprayer, temperature-sensitive automatic detection device is arranged on the single battery management system control of the electric vehicle
In device processed, controller further includes extinguishing device and opens parameter setting apparatus, and it is described that the fire extinguisher, which opens parameter setting apparatus,
The vehicle battery management system of electric vehicle or the car-mounted terminal backstage of the electric vehicle.
This battery case extinguishing device is disadvantageous in that：The device is only monitored by temperature sensor in battery case
Monitoring by all kinds of means is not implemented in portion's environment, and the electric appliance in protection battery case is also considered not in the species of extinguishing device.
Practical new content
This is practical newly in order to solve above-mentioned the deficiencies in the prior art, provides new energy car battery case extinguishing device, is somebody's turn to do
Device realizes extinction using gas and dry-chemical fire extinguishing phase by way of setting dry powder box on the gas pipeline in fire-smothering gear
With reference to so as to the fire for putting out battery case much sooner and can ensureing that its equipment is without damage.
New energy car battery case extinguishing device is passed including sensor, fire-smothering gear and the reception inside battery case
Sensor signal and control extinguishing device controller, the fire-smothering gear by gas bomb, by being located at gas bomb bottleneck
The gas pipeline and gas pipeline that solenoid valve is connected with gas bomb are tightly connected and the internal dry powder box equipped with dry powder forms.
Preferably, the gas pipeline is being equipped with stomata with the junction of dry powder box.
Preferably, the dry powder box is located at the top of battery case and is evenly distributed on gas pipeline.
Preferably, the sensor includes temperature sensor, smoke sensor device and pressure sensor.
Compared with prior art, this practical new advantageous effect is：
(1) device can more fast and effectively be disappeared firing accident by the combination of extinction using gas and dry-chemical fire extinguishing
It goes out, ensures that the extent of damage of equipment is preferably minimized；
(2) device, can be effectively by thing of catching fire by set temperature sensor, smoke sensor device and pressure sensor
Therefore the stage simultaneously can be with the start and stop of intelligent control extinguishing device in the early stage for elimination.
Description of the drawings
Fig. 1 is the utility model structure chart；
Fig. 2 is the utility model intelligence control system figure；
In figure：1 battery case, 2 gas bombs, 3 dry powder boxes, 4 controllers, 5 gas pipelines, 6 solenoid valves, 7 sensors, 71 temperature
Sensor, 72 smoke sensor devices, 73 pressure sensors.
Specific embodiment
Below in conjunction with the attached drawing in this practical new embodiment, the technical solution in this practical new embodiment is carried out
It clearly and completely describes, it is clear that described embodiment is only this practical new part of the embodiment rather than whole
Embodiment.Based on this it is practical it is new in embodiment, those of ordinary skill in the art are without making creative work
All other embodiments obtained belong to the scope of this practical new protection.
New energy car battery case extinguishing device is passed including sensor 7, fire-smothering gear and the reception inside battery case
7 signal of sensor and control extinguishing device controller 4, the fire-smothering gear by gas bomb 2, by being located at 2 bottles of gas bomb
Mouthful solenoid valve 6 be connected with gas bomb 2 gas pipeline 5, be arranged on gas pipeline 5 the internal dry powder box 3 equipped with dry powder
Composition, the gas pipeline 5 with the junction of dry powder box 3 be equipped with stomata, the dry powder box 3 be located at the top of battery case 1 and
It is evenly distributed on gas pipeline 5.
Attached drawing 1-2 is referred to, a kind of this practical new technical solution of offer：
A kind of automobile mounted battery case extinguishing device, in inside set temperature sensor 71, the smoke sensor device of battery case 1
72 and pressure sensor 73 monitor the environment inside battery case 1, when having the omen caught fire inside battery case 1, internal meeting
There is situations such as temperature rising, generation smog to generate, the signal that temperature sensor 71 and smoke sensor device 72 are monitored passes through
The mode of 2.4G wireless telecommunications is transferred to controller (model：JB-QB-JBF5012) 4, controller 4 is by the signal received with setting
Fixed threshold values compares, and is then beaten if greater than set threshold values by the solenoid valve 6 in RS485 signal line traffic control fire extinguishing systems
It opens, the gas after solenoid valve 6 is opened in gas bomb 2 into gas pipeline 5 and then flows into dry powder box 3 under the effect of the pressure, does
Powder box 3 ruptures under gas pressure effect, and the dry powder in dry powder box in a flash 3 ruptured in dry powder box 3, which is trickled down out, to be covered
On battery, the generation of firing accident is prevented, and then inert gas is constantly into battery case 1, since inert gas is not supported to fire
The characteristic of burning fundamentally prevents the generation of firing accident, and inert gas constantly causes 1 inside pressure of battery case into battery case
Power increases, the pressure transmission that pressure sensor 73 monitor to controller 4, controller 4 by the pressure value signal received and
Set threshold values compares, and the solenoid valve 4 in extinguishing device is then controlled to close if greater than threshold values, inert gas will not enter back into
Battery case.
Above the embodiment only expresses this practical new preferred embodiment, and description is more specific and detailed, but
Can not the limitation to this practical new the scope of the claims therefore be interpreted as.It should be pointed out that the common skill for this field
For art personnel, on the premise of this practical new design is not departed from, several deformations can also be made, improves and substitutes, these
Belong to this practical new protection domain.Therefore, the protection domain of this practical new patent should be determined by the appended claims.
