Abstract

The utility model relates to an accumulator, particularly a started full-sealed accumulator tank. The utility model is provided with a purpose-made battery cover and a small cover board in addition, based on the existing accumulators, and a gas-liquid separating tank is arranged on the battery cover and the small cover board. After the respective heat sealing of the battery cover and a battery case, the small cover board and the battery cover, a gas-liquid separate channel the end of which is provided with an air exit hole that is provided with an acid-proof gas filtering piece is formed between the small cover board and the battery cover. As for the acid liquor, the accumulator is in the sealed condition all the time and the water loss is reduced to realize the maintenance free characteristic of the accumulator without adding water, and the utility model has fine anti-knock quality to prevent the detonation generating when the accumulator is charged.

Description

Start type fully-sealed Plastic accumulator groove

The utility model relates to a kind of storage battery, especially employs hermetically sealed Plastic accumulator groove for a kind of.

Present storage battery majority is on the battery cover at cell through lid, leave the inlet that to open, in order to filling electrolyte or supplementing water, and the gas that battery is produced in electrochemical reaction is discharged battery case, although install the various forms vent plug additional at inlet, overflow but all can't solve battery leakage and acid mist, therefore cause battery to catch fire, the injury problem of the environmental pollution and the person.

The purpose of this utility model is: cooperate the improvement of integral battery door, design rising of a kind of sealing fully and employ the Plastic accumulator groove, make the storage battery heat-sealing, isolate acid solution and gas for formation liquid gas split tunnel after the one, realized that battery need not add the non-maintaining property of water, and good explosion-proof has been arranged.

The novel purpose of this reality is achieved in that the battery cover that is complementary with it is housed on battery case, wherein on battery cover, be provided with battery status display installing hole and pole, offer the steam vent that the anti-acid acid filtering sheet is installed at the minor flaps two ends, on corresponding with minor flaps of battery cover, be provided with liquid gas separating tank, be provided with the liquid return mouth in the liquid gas separating tank on the battery cover on corresponding with minor flaps, the biend of battery case is provided with reinforcement.

Thereby the utility model is owing to adopted above-mentioned structure to produce following good effect: the anacidity hydrorrhea goes out, and battery remains cleaning, and car body and circuit are not had corrosion; Storage battery is realized sealing fully, prevents the unexpected contact of user acid solution, guarantees personal safety; Reduce water loss, realized that battery need not add the non-maintaining property of water; Have good explosion-proof, prevent the charging blast; Can use with the battery condition display is equipped, can show battery charge state at any time, for the user provides very big convenience.

Below in conjunction with drawings and Examples the utility model is described further;

Fig. 1 is this practical structural representation; Fig. 2 is an installation diagram of the present utility model.

Among the figure lead-calcium alloy plate behind the assembly welding is assembled in the battery case 1, connecting pole 6 back and on the battery cover 2 with through-wall welding between monomer utmost point group links to each other, battery case 1 and battery cover 2 are carried out the heat-sealing first time, after adding acid solution to battery, the heat-sealing back tightens liquid plug 11, again battery cover 2 and minor flaps 4 are carried out the heat-sealing second time, battery after the heat-sealing has been realized totally-enclosed, because of on 4 corresponding of battery cover 2 and minor flaps, being provided with liquid gas separating tank 5, so after the battery heat-sealing, between battery cover 2 and minor flaps 4, formed liquid gas split tunnel (also claiming the labyrinth), after cell electrochemical reaction produces acid mist, isolate acid solution and gas through liquid gas split tunnel, acid solution is back in the battery case by liquid return mouth 9, gas is then discharged outside the battery by exhaust outlet 8 by the anti-acid acid filtering sheet 7 of channel end, the acid solution battery is in sealing state all the time, pollution-free, in addition between battery cover 2 and the battery case 1, also can connect by screw 13, also can peg graft between battery cover 2 and the minor flaps 4 by tongue-and-groove 12, on battery cover 2, can the battery status display be installed by battery status display installing hole 3, indicate the state of battery charge amount, realized that battery is hermetically sealed, materials such as the described anti-acid acid filtering sheet 7 useable glass cottons of present embodiment are made.

Claims
