Abstract

The utility model relates to a high-capacity sealing lead-acid accumulator without maintenance, which is characterized in that a casing, an inner cap and an outer adopts the ABS engineering plastics having the shock resistance performance for injection moulding. Polar plates and partition plates are arranged alternately and moderately compactly, and the slab lattice of the polar plate is made of the multicomponent alloy. The partition plate is the cellophane of boron and silicon, in use, users do not need to detect the specific gravity and supplement fluid, and the utility model has the advantages of good large current characteristics, long service life, the floating charge service life above 12 to 18 years, large rated capacity and producing the serial products of 200 to 2000 ampere-hour and is suitable for the ideal direct current power supply of stored-program control exchanges, microwave machines, carrier machines, computers, switch starters, locomotives, beacon lights, emergency lamps, etc.

Description

High-capacity sealing lead-acid accumulator without maintenance

The utility model is the high-capacity sealed maintenance-free lead accumulator of a kind of long-life, fixed.

At present, in the lead acid accumulator of the general electrolyte that flows, the charging later stage has a large amount of bubbles to occur, the positive plate lead powder is come off, the negative plate lead powder is soft, and the electrolyte loss that is caused by electrolysis in charging process need be carried out maintenance works such as fluid infusion and mensuration electrolyte density.The drawbacks such as acid, flow liquid and discharging acid mist of oozing of lead acid accumulator bring harm for transportation and applying unit, and have limited the range of application of storage battery.In the use, especially in dynamic use, the positive plate material comes off easily, is directed at capacity decline, short circuit, reduction of service life.Domesticly begin to develop the colloidal electrolyte lead acid accumulator from the seventies, though tentatively solved the problems referred to above, but still exist a series of problems: the internal resistance of cell is bigger, during charging, the two poles of the earth produce gas and tear adhesive between colloid and pole plate, engender liquid--and glue two tilts when placing battery, oozes that acid, flow liquid, colloid are easily chapped, invertibity is poor, the positive plate seriously corroded, useful life is short.Industrial Co., Ltd. of this Toyota application " sealed lead-acid accumulator free from maintenance " patent, application number are to authorize on April 22nd, 91 2 12683.3,92, are the following fixed sealed lead-acid accumulator free from maintenance of 200 ampere-hours.

Task of the present utility model provides the high-capacity sealed maintenance-free lead accumulator that a kind of volume is little, in light weight, do not spatter acid, long-life, fixed.

To achieve these goals, solution of the present utility model is: be made up of shell, pole plate, bus-bar, terminals etc., it is characterized in that: shell has single lattice, two lattice or many lattice, its positive and negative electrode grid is thicker, can have the lattice plate to be divided into single lattice in the enclosure, in each single lattice by negative plate, dividing plate, positive plate, the alternate moderate tight placement of dividing plate; Its shell, inner cap and enclosing cover are the ABS engineering plastics injection mo(u)ldings of adopting impact resistance, and its positive plate grid is to cast with the low-stibium multicomponent alloy, and the negative plate grid is to cast with lead-calcium multielement alloy, and dividing plate is a borosilicate cellophane.The positive plate of each single lattice or negative plate weld with bus-bar respectively and connect, and closing has the inner cap of steam vent, add dilute sulfuric acid from steam vent.On bus-bar, draw the positive and negative electrode terminals respectively, be coated with gluing at the interface of shell, the enclosing cover that closes, charging, detection, packing product.

The utlity model has following advantage: 1. non-maintaining, the user in use need not survey proportion and fluid infusion; 2. the heavy-current discharge characteristic is good, can use under low pressure and full temperature; 3. long service life is other 4～6 times of starting lead acid accumulator, and the floating charge working life is more than 12～18 years; 4. can comprehensively place, assembled battery installation floor space is little, stackable use; 5. vibration resistance is convenient to carrying, and the anacidity hydrorrhea goes out, and avoids external corrosion; 6. storage characteristic good (being that self discharge is little) was at room temperature stored, and also maintained 60% capacity through 8 months; 7. rated capacity is big, can produce the series of products of 200～2000 ampere-hours, is applicable to desirable DC power supply such as stored-program control exchange, microwave machine, carrier terminal equipment, computer, switch activated, traction locomotive, navigation light, emergency light.

Below in conjunction with accompanying drawing, the utility model is described in detail:

The utility model is made up of shell (1), pole plate (4,6), bus-bar (7), terminals (8) etc., it is characterized in that: shell (1) has single lattice, two lattice or many lattice, positive/negative plate (6,4) grid is thicker, in shell (1), can have lattice plate (3) to be divided into single lattice, in each single lattice by negative plate (4), dividing plate (5), positive plate (6), the alternate moderate tight placement of dividing plate (5); Its shell (1), inner cap (9), enclosing cover (2) are the ABS engineering plastics injection mo(u)ldings of adopting impact resistance, positive plate (6) grid is to cast with the low-stibium multicomponent alloy, negative plate (4) grid is to cast with lead-calcium multielement alloy, and dividing plate (5) is a borosilicate cellophane; Positive plate of each single lattice (6) or negative plate (4) weld with bus-bar (7) respectively and connect, steam vent the is arranged inner cap (9) of (10) closes, add dilute sulfuric acid from steam vent (10), on bus-bar (7), draw the terminals (8) of positive and negative electrode (6,4) respectively, interface at shell (1) is coated with gluing, the enclosing cover that closes (2), charging, detection, packing product.Shown in Fig. 1,2,3,4.

Principle of the present utility model: the oxygen that takes place from positive plate (6) during charging is absorbed by negative plate (4) reaction rapidly, is reduced into water, controls hydrogen simultaneously and takes place from negative plate (4).Whole oxygen that the gas that can reach is produced when the chemical combination rate can make charge in batteries under special cases again are chemical combination again.Dividing plate (5) is configured between pole plate (4,6) with high-density state, prevents that pole plate (4,6) active material from coming off.Pole plate (4,6) can be preserved with dividing plate (5) and be placed on the required electrolyte of all batteries capacity, so can guarantee that the battery depletion is few, the life-span is long.Because the electrolyte of battery keeps performance good, battery is inverted and is used also is possible.
