Description
Technical field
The utility model relates to a kind of automatic vent type secondary battery anti-explosion prior-warning device.
Background technology
Storage battery is the battery combination that places in the metal battery case, is widely used on various engineering car and the engineer equipment.When being applied to harbour, railway, goods yard, warehouse etc. and containing the place of explosive mixture, storage battery safety is most important, and improper use very easily causes accumulator explosion.
Storage battery tends to produce gas in charge and discharge process, when gas increases to a certain degree the time, the battery case internal pressure is sharply increased, if can not in time get rid of gas, blasts easily.When containing the operation of inflammable and explosive place, storage battery is blasted and can be caused unpredictable consequence.
Chinese patent CN101867029A discloses a kind of anti-explosion exhaust structure of battery, and it comprises casing, guide groove, venting, safety valve, flexible pipe.When producing gas, battery pack discharges outside the battery case by guide groove and flexible pipe.This apparatus structure is complicated, adopts high-temperature insulation material to make, and manufacturing cost is high.And in the time of can't satisfying timely exhaust requirements, do not possess the danger early warning system, functional reliability is lower.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defects that prior art exists, and provides a kind of simple in structure, low cost of manufacture, the automatic vent type secondary battery anti-explosion prior-warning device that functional reliability is high.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of automatic vent type secondary battery anti-explosion prior-warning device, it comprises slide block, slide block is located in the battery cover cavity, battery cover is located at the battery case top, the battery cover bottom is provided with the connected entrance that communicates with battery case inside, battery cover top is provided with the exhaust outlet that communicates with ambient atmosphere, and slide block one side links to each other with spring one end, and the spring other end is fixed on the battery cover; The slide block opposite side is provided with the conductive contact I.
Further, also comprise early warning circuit, early warning circuit is provided with the conductive contact II, and when not working, early warning circuit is in off-state.
Described early warning circuit is provided with buzzer or early-warning lamp.
Further, described slide block is the I shape slide block.
The utility model is simple in structure, compact, low cost of manufacture; It can realize automatic vent; Realize danger early warning, the battery operated situation of Real Time Monitoring, high efficiency, applied widely.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1, present embodiment comprises slide block 6, slide block 6 is located in battery cover 2 cavitys, battery cover 2 is located at battery case 1 top, battery cover 2 bottoms are provided with the connected entrance 3 that communicates with battery case 1 inside, battery cover 2 tops are provided with the exhaust outlet 7 that communicates with ambient atmosphere, and slide block 6 one sides link to each other with spring 5 one ends, and spring 5 other ends are fixed on the battery cover 2 by spring mounting hole 4; Slide block 6 opposite sides are provided with conductive contact I 8-1.
Also be provided with early warning circuit, early warning circuit is provided with conductive contact II 8-2, and when not working, early warning circuit is in off-state.
Described early warning circuit is provided with buzzer 9.
Described slide block 6 is the I shape slide block.
During use, according to battery pack related experiment data, the pretightning force of default spring 5, when producing a large amount of gas in the battery charge and discharge process, battery case 1 internal pressure sharply increases, and promotes slide block 6 motions, and slide block 6 moves to a certain degree, exhaust outlet 7 communicates with battery case 1 inside by connected entrance 3, and battery case 1 interior gas is expelled in the atmosphere through connected entrance 3, exhaust outlet 7.Simultaneously, the conductive contact II 8-2 of the conductive contact I 8-1 on the slide block 6 and early warning circuit connects, and the early warning circuit conducting is in normal operating conditions, and buzzer 9 sends warning, plays the warning effect.If battery case 1 interior gas fails in time to discharge, buzzer 9 will continue alarm.After battery case 1 interior gas emptying, battery case 1 internal pressure reduces, and under the effect of spring 5 elastic force, slide block 6 resets, all clear.
