Abstract
The utility model discloses an accumulator without maintenance comprising a casing. A positive and a negative plates are arranged in the casing and are separated through a diaphragm sucking the electrolyte between them. An inner cap is arranged above the positive and the negative plate, and the middle part of the inner cap is provided with pores. The negative plate is connected with the terminal of the negative electrode outside the casing through the extraction device of the negative electrode, after connected with a voltage dropping block, the positive plate is connected with the terminal of the positive electrode outside the casing. The utility model has the advantages of simple structure and low voltage.
Description
The utility model relates to a kind of electric energy storage system, specifically a kind of storage battery.
Lead accumulator is extensive with its material source, technology is simple, cost is low and be widely used, superior functions such as the totally enclosed type lead acid accumulator is aesthetic in appearance, pollution-free with it, saving cost, Maintenance free develop rapidly, but existing this maintenance free cell, structure is square, there is not the step-down piece, general nominal voltage is 2 volts a cell tension, can not replace with general dry battery and use, and makes troubles for the use of some occasion.
The purpose of this utility model is to provide that a kind of voltage is lower, scope of application maintenance free cell widely.
Technical solution of the present utility model is:
A kind of maintenance free cell, comprise shell, the difference of itself and prior art is: dress positive plate, negative plate in the shell, there is the barrier film of electrolyte to separate by suction between positive plate, the negative plate, inner cap is contained in the top of positive and negative pole plate, opens pore in the middle of the inner cap, and negative plate is connected by the outer negative pole exit of negative pole ejector and shell, positive plate is with after the voltage drop briquetting is connected, and the anodal exit outer with shell is connected.
The voltage drop briquetting is the diode of a pair of parallel connected in reverse phase.
Shell is the garden tubular, and anodal exit is positioned at the top of shell, and the negative pole exit is positioned at the bottom of shell.
Positive plate adopts two grids that contain positive electrode active material, and positive plate also is connected with positive bus, and then is connected with the voltage drop briquetting; Negative plate adopts three grids that contain negative electrode active material, and negative plate also is connected with negative bus-bar, and then is connected with the negative pole ejector.
The air vent hole loam cake safety valve of inner cap, safety valve are rubber films that coincide with the inner cap air vent hole.
The filter air cushion is placed in the inner cap top in the cavity around the safety valve.
Shell is adorned heat-shrinkable T bush (plastic film cover) outward.
The utility model is simple in structure, and the nominal voltage of battery is reduced, and particularly when selecting the diode of suitable specification for use, can make the nominal voltage of storage battery reduce to 1.5V; Simultaneously because the garden of employing cartridge type profile make it exchange use with zinc-manganese dioxide dry cell easily, thereby the scope of application is more extensive than common maintenance free cell.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the circuit diagram of voltage drop briquetting among Fig. 1.
A kind of maintenance free cell, garden tubular insulation crust 13, interior dress positive plate 11, negative plate 5, they are to be coated with respectively with the positive and negative electrode active material to form on the grid that high hydrogen overpotential lead-calcium alloy is cast.Positive plate 11 adopts two, and they connect by positive bus 3.Negative plate adopts three, connects by negative bus-bar 8 between them, and negative bus-bar 8 connects negative pole and draws copper bar 9 (or negative outside wire), and negative pole is drawn copper bar 9 and is connected with the negative pole exit 14 that is positioned at shell 13 bottoms.Positive plate 11, negative plate 5 are spaced, and separate with high imbibition, the cotton barrier film 12 of low-resistance ultra-fine fibre glass between the positive and negative pole plate, and inhaling on the barrier film 12 has electrolyte, and it is in poor electrolyte state.Lid inner cap 4 above positive and negative pole plate, pore 15 is opened in the centre of inner cap 4, and air vent hole 15 loam cake safety valves 6, safety valve 6 are rubber films that coincide with inner cap air vent hole 15, and when inner pressure of battery increases when too high, safety valve can be backed down emptying, prevents blast.Positive bus 3 connects voltage drop briquetting 2, voltage drop briquetting 2 is diodes (ZCN type) of a pair of reverse parallel connection, it can have the voltage drop about 0.5V, making output voltage is 1.5V, can be used as the current path (certainly, the voltage drop briquetting also can adopt other appropriate device) that battery fills, puts again.Voltage drop briquetting 2 is connected with the anodal exit 1 that is contained in cover top portion.Above inner cap 4, safety valve 6 around place filter air cushion 7 in the cavity, but the acid gas of elimination from overflowing between inner cap 4, the safety valve 6 gone back the suit protective sleeve in the outside of shell 13---heat-shrinkable T bush (plastic film cover).
