Background technology
Storage battery is with low cost because of it, stable performance, the advantage such as easy to use, obtains using very widely at daily and industrial circle.Storage battery in use, inside tends to produce gas, causes cell internal pressure constantly to raise, accumulator pole might be blasted.In a lot of hazardous environments, accumulator explosion can produce very serious consequence.Therefore, the explosion-proof performance of storage battery is very important performance index.
In the present secondary battery anti-explosion technology, the most commonly use the secondary battery anti-explosion cover plate, be processed with vulnerable area on the battery anti-explosion cover plate, when the pressure of inside battery raises and when surpassing the force value that vulnerable area can bear, the vulnerable area fracture reduces rapidly cell internal pressure, avoids blasting.Such method has improved the explosion-proof performance of storage battery simply and effectively, but this is a kind of explosion-proof method of parts self destruction formula, and namely an explosion-proof covering board can only use once, not can be recycled, and scrappage is higher, has caused the not convenient of the waste of material and use.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defects that prior art exists, and provides a kind of and can be recycled, and scrappage is lower, and storage battery applied widely can be monitored explosion-protection equipment.
The technical solution adopted for the present invention to solve the technical problems is: a kind of storage battery can be monitored explosion-protection equipment, comprise valve body, be provided with plunger in the valve body, plunger both sides cylinder is respectively equipped with wedge shape boss I, wedge shape boss II, wedge shape boss I end face, wedge shape boss II end face contact with plunger both sides cylinder respectively, the wedge shape boss I outside is provided with the wedge I, the wedge shape boss II outside is provided with the wedge II, wedge I one side is provided with the spring I, wedge II one side is provided with the spring II, and spring I and spring II end all are fixed on the valve interior wall.
Further, described plunger upper part and bottom are respectively equipped with rubber seal I and rubber seal II, are beneficial to strengthen sealing property.
Further, described rubber seal I and rubber seal II are the anti-corrosive rubber seal.
Further, described plunger is provided with the anticreep connecting line, and plunger is connected with the cover plate of storage battery by the anticreep connecting line.
Further, described wedge I, wedge II link to each other with warning circuit by circuit lead I, circuit lead II respectively.
Further, described wedge I, wedge II are the metal wedge.
Further, described plunger is the ambroin plunger.
During use, the present invention is installed on the cover plate of storage battery, the present invention has the effect that discharges internal storage battery pressure and sealing, and after battery occurs to leak to staff's signal that gives the alarm.
The present invention is simple in structure, reliable, and is safe and practical, can effectively control the internal pressure of storage battery, prevents storage battery and explodes because internal pressure is too high, improves the battery anti-explosion performance.Avoid the damage of explosion-proof battery cover plate, be conducive to save material, improved the Practical Performance of battery.The leak condition of the present invention's energy Real Time Monitoring storage battery, and in time leakage is processed, security performance is high.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation;
Fig. 2 is embodiment illustrated in fig. 1 and battery cap board assembling structure schematic diagram.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, the present embodiment comprises valve body 5, be provided with plunger 2 in the valve body 5, plunger 2 both sides cylinders are respectively equipped with wedge shape boss I 9-1, wedge shape boss II 9-2, wedge shape boss I 9-1 end face, wedge shape boss II 9-2 end face contact with plunger 2 both sides cylinders respectively, the wedge shape boss I 9-1 outside is provided with wedge I 6-1, the wedge shape boss II 9-2 outside is provided with wedge II 6-2, wedge I 6-1 one side is provided with spring I 8-1, wedge II 6-2 one side is provided with spring II 8-2, and spring I 8-1 and spring II 8-2 end all are fixed on valve body 5 inwalls.
Described plunger 2 upper and lowers are respectively equipped with rubber seal I 3 and rubber seal II 7, are beneficial to strengthen sealing property.
Described rubber seal I 3 and rubber seal II 7 are the anti-corrosive rubber seal.
Described plunger 2 is provided with anticreep connecting line 4, and plunger 2 is connected with the cover plate 11 of storage battery 10 by anticreep connecting line 4.
Described wedge I 6-1, wedge II 6-2 link to each other with warning circuit by circuit lead I 1-1, circuit lead II 1-2 respectively.
Described wedge I 6-1, wedge II 6-2 are the metal wedge.
Described plunger 2 is the ambroin plunger.
Before the use, at cover plate 11 processing air vent hole and the threaded connection holes of storage battery 10, the storage battery that is beneficial to install the present invention can be monitored explosion-protection equipment.And circuit lead I 1-1, circuit lead II 1-2 all be connected to warning circuit.
When the pressure of storage battery 10 inside raises, the gas push plunger 2 that produces moves up, relative motion occurs in wedge shape boss I 9-1 and wedge I 6-1, wedge shape boss II 9-2 and wedge II 6-2, but still keep in touch each other, spring I 8-1, spring II 8-2 are squeezed, and wedge I 6-1, wedge II 6-2 are all to two side shiftings.When storage battery 11 inside gas pressure when continue raising, on continuing, moves plunger 2, go out the cover plate 11 of storage battery 10 under the gas pressure effect, wedge shape boss I 9-1 and wedge I 6-1 wedge shape contact-making surface come off, and wedge shape boss II 9-2 and wedge II 6-2 wedge shape contact-making surface also come off.Under the effect of the anticreep connecting line 4 that links to each other with the cover plate 11 of storage battery 10, be conducive to prevent that plunger 2 from going out valve body 5 outsides and lose.
