Abstract

The utility model belongs to the technical field of lead-acid accumulator. Two groups of polar plate devices with monomer structure of the lead-acid accumulator are arranged in an accumulator container, and each group of the polar plate devices comprises positive plates, negative plates, partition boards and bottom closing strips. The positive plates are tubular, and the bottom closing strips are moulded plastics. Connecting strips whose interiors are lined with copper plates are connected between the adjacent positive and negative terminals on the cell cover, and exposed connecting bolts are reduced. The utility model, whose service life is prolonged up to 3 to 4 years and whose cost is reduced by 50-60 yuan, saves lead and is of safe operation thereby.

Description

Lead acid accumulator for IC engine

The utility model belongs to the lead acid accumulator technical field.

The storage battery of beeliner application at present is the old product in the sixties mostly, monomer structure, every cell voltage 2V, each two pole of both positive and negative polarity, exposed bolted copper coin connects, at the bottom of positive plate was tubular type, lead sealing, negative plate was a paste spread type, and the shortcoming of this old-fashioned storage battery is:

1, monomer structure, every 4V voltage just needs two storage batterys, 8 bolts to connect, contact is many, and the one, contact resistance is big, influences locomotive and starts, the 2nd, locomotive is in vibrations, move in the environment that jolts, in case bolt looseness easily produces spark, the hydrogen that spark produces as internal storage battery, the danger of blast is just arranged, influence the traffic safety of locomotive.

2, at the bottom of positive plate was lead sealing, short circuit was caused in the easily heavy bottom that combines in of active material in the use, has influenced useful life, makes and shortens to 1.5-2 useful life;

3, consume plumbous material, copper material is many, the cost height.

The internal combustion engine vehicle lead-acid battery that the purpose of this utility model is few, the long service life of a kind of connecting bolt of design, cost is low.

The utility model comprises battery case, the pole plate device and the electrolyte of the lead acid accumulator of monomer structure are housed in battery case, on battery case, be stamped battery cover, battery cover is provided with positive terminal, vent plug, negative terminal, the pole plate device comprises spaced positive plate that is connected with positive terminal and the negative plate that is connected with negative terminal, the dividing plate that the both sides, front and back of each positive plate are provided with, the back cover bar that the bottom of positive plate is provided with, the length that it is characterized in that battery case and battery cover doubles, two groups of pole plate devices that structure is identical are housed in battery case, back cover bar wherein is the plastic strip of moulding, positive plate is a tubular plate, battery cover is provided with two positive terminals, vent plug, negative terminal, between adjacent positive terminal and negative terminal, be connected with intercell connector, stud with copper coin in the intercell connector.

Because it is couple structure that the utility model changes monomer structure, make the voltage of every storage battery bring up to 4V by 2V, adjacent positive terminal adopts the intercell connector of interior edge copper coin to be connected with negative terminal, exposed connecting bolt is reduced, every 4V battery reduces to 2 bolts by 8 bolts, tubular type positive plate and plastics back cover bar have been adopted, prevented that storage battery from using the later stage to combine in the short circuit phenomenon that cause the bottom because of active material is heavy, prolonged useful life, therefore, the utility model is safe in utilization, and the life-span can reach 3-4, exceeded one times of UIC Standards UIC854R, every storage battery is saved plumbous 5kg, cost reduces 50-60 unit.

Accompanying drawing shows embodiment of the present utility model, wherein

Fig. 1 is the front view of embodiment;

Fig. 2 is the vertical view of embodiment;

Fig. 3 is the left view of embodiment.

In the present embodiment, the long 405mm of the cell jar of vulcanie compression molding (5), the pole plate device of two groups of lead acid accumulators is housed in it and uses special-purpose sulfuric acid, the electrolyte that pure water is mixed with, every group of pole plate device comprises: 9 tubular type positive plates of making of lead-antimony alloy and active material (8), 10 paste spread type negative plates of making of lead-antimony alloy and active material (11), 18 dividing plates (14) that microcellular rubber is made, 9 back cover bars (16) with plastic shaping, positive plate (8) is spaced with negative plate (11), dividing plate (14) is being placed in both sides before and after each root positive plate (8), use back cover bar (16) back cover of plastic shaping in the bottom of each positive plate (8), battery cover (2) in the useful vulcanie making of battery case (5) loam cake, battery cover (2) is provided with two positive terminals (1), vent plug (3), negative terminal (7), positive terminal (1) is connected with positive plate (8), negative terminal (7) is connected with negative plate (11), between adjacent positive terminal (1) and negative terminal (7), be connected intercell connector (4), intercell connector (4) is made of lead-antimony alloy, inside studs with copper coin (6), the packing ring (9) that soft rubber is made is housed between vent plug (3) and battery cover (2); buoy (10) is plugged on vent plug (3) and goes up and stretch out; the lead pipe (12) that is socketed on positive terminal (1) and the negative terminal (7) melts back and battery cover (2) sealing downwards; positive terminal terminal (17) is housed being positioned on the positive terminal (1) of storage battery side; negative terminal terminal (13) is housed being positioned on the negative terminal (7) of storage battery side; for easy to use; respectively be provided with carrying handle (15) in the both sides of battery case (5), carrying handle (15) is selected the making of multiply nylon rope for use.
