Specific embodiment
The feature of the utility model and other correlated characteristics are made further specifically by embodiment below in conjunction with attached drawing
It is bright, in order to the understanding of technical staff of the same trade:
Such as Fig. 1-2, label 1-7 is respectively as follows: lithium battery ontology 1, encapsulation compound 2, breathing equipment 3, guard shield in figure
Cabinet 4, guard shield case lid 5, fire arrester 6, check valve 7.
Embodiment: as shown in Figs. 1-2, the present embodiment is specifically related to a kind of synthesis explosion-proof protection structure of lithium battery power supply,
The synthesis explosion-proof protection structure uses steel guard shield, and internal lithium battery ontology periphery encapsulation has encapsulation compound, can have
Effect avoids the presence of incendiary source, and further by the way that explosion-proof decompression device is arranged on guard shield, can send out in lithium battery power supply
Raw extreme failure leads to that air pressure is unidirectionally discharged into the external world when relief valve excessive because of cell internal pressure opening, realizes lithium battery
The synthesis explosive-proof protector in source.
As shown in Figs. 1-2, the synthesis explosion-proof protection structure of one of the present embodiment lithium battery power supply includes outer by protecting
The guard shield that housing box lid 5 and guard shield cabinet 4 are constituted, guard shield inside form closed space, are inside placed with and pour
Mould group is sealed, encapsulation mould group is generally adapted with the shape inside guard shield cabinet 4, i.e. the inner wall with guard shield cabinet 4
It fits closely, makes its firm position, and encapsulation mould group only accounts for the major part of the guard shield inner space, makes remaining space
As reserved cavity.Guard shield in the present embodiment uses steel guard shield, can bear at least pressure of 1.5MPa, and set
It is equipped with the explosion suppresion surface of sufficient size, it is ensured that the flame proof protection for meeting equipment in explosive gas atmosphere requires.
As shown in Figure 1, 2, encapsulation mould group includes lithium battery ontology 1 and encapsulation compound 2, when lithium battery ontology 1 occurs
When failure, the relief valve on lithium battery ontology 1 can be opened and the gas generated inside it is discharged, and release stress in time.It pours
Envelope compound 2 pours the periphery for being encapsulated in lithium battery ontology 1, and during encapsulation, encapsulation compound 2 lets out removing for lithium battery ontology 1
All exposed parts outside pressure valve carry out encapsulation, avoid that there are incendiary sources.Relief valve on lithium battery ontology 1 is through breathing equipment 3
It is connected with the reserved cavity inside guard shield, breathing equipment 3 is that the flame-proof type with back-fire relief function breathes element, and it is released
Expected rate of gas release matches when the rate of deflation body is with lithium battery 1 failure of ontology, to ensure that lithium battery ontology 1 exists
Extreme failure occurs when causing internal pressure excessive and then opening relief valve can by breathing equipment 3 smoothly release gas to anti-
The reserved cavity of interior of shell is protected to reduce the pressure inside lithium battery ontology 1, battery is made to enter safe condition.
As shown in Figs. 1-2, an explosion-proof relief hole is also provided on guard shield, which will be in guard shield
The reserved cavity in portion is connected to outside, and the explosion-proof decompression device to match with its internal diameter is provided in explosion-proof relief hole,
The explosion-proof decompression device includes from outside guard shield to the fire arrester 6 and check valve 7 set gradually inside guard shield, back-fire relief
Device 6 and check valve 7 match, and the gas in the reserved cavity inside guard shield is allowed to pass through fire arrester 6 and check valve 7
It is discharged to the outside in air, while outside air being prevented to enter inside guard shield by fire arrester, in order to avoid jeopardize therein
The safety of lithium battery power supply, meanwhile, which is flame-proof type fire arrester, and the flame proof that can further improve lithium battery power supply is protected
Protective function.
As shown in Figs. 1-2, the quantity of the lithium battery ontology 1 in the present embodiment can be 1, be also possible to two or more
It is more, only it need to ensure to have reserved cavity for the possible pressure release demand of lithium battery ontology 1, each lithium battery ontology 1 inside guard shield
All should by encapsulation compound carry out encapsulation, avoid it is exposed outside.Explosion-proof decompression device in the present embodiment is mounted on guard shield
On case lid 5, reserved cavity is then located at the top of the encapsulation mould group inside guard shield.
As shown in Figs. 1-2, the explosive-proof protector principle of the synthesis explosion-proof protection structure of the lithium battery power supply in the present embodiment are as follows:
(1) when 1 failure of lithium battery ontology causes cell internal pressure excessive, the relief valve on lithium battery ontology 1 will be automatic
It opens, gas pressure passes through the breathing equipment 3 with back-fire relief function connected thereon first and is discharged into pouring inside guard shield
The reserved cavity on the top of mould group is sealed, is then discharged into outside protection by the check valve 7 and fire arrester 6 that are arranged on guard shield again
Outside shell, therefore not will form excessively high pressure inside guard shield, the pressure of simultaneous faults inside battery be released after i.e.
Switch to safe condition.
(2) encapsulation has been carried out to lithium battery ontology 1 using encapsulation compound inside guard shield, therefore inside guard shield
There is no any exposed electric component, avoid the presence of incendiary source, even if 1 failure of lithium battery ontology leads to gas or organic matter
Matter is discharged into reserved cavity, will not be caused to burn because of electrical cause or be exploded.
(3) when extreme failure occurs for lithium battery ontology 1 lead to that explosion time occurs inside it, due to back-fire relief function
Flame-proof type breathes the presence of element, and will not generate explosion risk to external environment influences.
(4) when extreme failure occurs for lithium battery ontology 1, and the encapsulation explosion prevention function of encapsulation mould group is caused to be destroyed, due to anti-
The presence of the flame-proof type fire arrester 6 and check valve 7 that are arranged on shield shell and guard shield will not generate pole to external environment
End harm, and guard shield is steel guard shield, can bear the pressure of 1.5MPa, has thereby further ensured that explosion will not
Influence guard shield external environment.
The beneficial effect of the present embodiment is: by using the explosion-proof protection structure of synthesis, realizing the two of lithium battery power supply
Grade explosive-proof protector, greatly improves the explosive-proof protector grade of lithium battery power supply, lithium has been expanded in the safe handling of lithium battery power supply
Battery supply is in numerous industrial sites with explosion risk mixture ambient, such as underground coal mine and petrochemical enterprise production
The use scope in the places such as region.
