The utility model provides the accumulator with the advantages of favorable sealing performance, long service life, no pollution on environment and no maintenance.

Description

The valve-regulated sealed storage battery of ultra-strong current starting

The utility model relates to a kind of storage battery, it is the valve-regulated sealed storage battery that can supply with the super large starting current.

Working the storage battery of employing needs moment that big electric current supply power consumption equipment is arranged, and all is to obtain with the way that increases battery capacity (Ah) both at home and abroad, must cause the wasting phenomenon of " low load with strong power " like this, sees it is extremely irrational from economic point of view.In addition, now use the equal valveless control of the starting battery hermetically-sealed construction of domestic production, sealing around its groove lid is with irritating pitch, heat-sealing, three kinds of forms of interior bonding, all can not obtain waste product, the sealing effectiveness that does not leak fully, thereby cause loss due to spoiled work and quality accident, particularly produce and emit acid gas, leakage sour water, contaminated environment, corrosion facility and harm health of human body.

The purpose of this utility model provides a kind ofly has the super large starting current, and the storage battery of good seal, long service life, free from environmental pollution, freedom from repairs.

The purpose of this utility model is achieved in that it comprises battery case, interior dress both positive and negative polarity group, connecting plate and binding post, an amount of electrolyte and valve control safety cap, it is characterized in that: its grid adopts the ridge and blage type structure, and wrap up: on one side the lug of grid is moved on near center line by the backup plate grid with glass mat, and on lug center line extended line, be designed to the main muscle of ridge impeller grid, straight-through lug, main muscle both sides distribution vein type diagonal bar and equidistant horizontal bar.

The main muscle of grid and vein type diagonal bar are by upwards overstriking gradually down.

Adopt two labyrinth type adhesive seal structures around the battery cover, six plastic cement safety valves of six single lattice central upper packing.

The battery case bottom is divided into six liquid storage tanks of giving the additional electrolyte of electrochemical reaction in the battery.

Details of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is a kind of embodiment organigram of the present utility model.

Fig. 2 is a hauling type grid schematic diagram.

Fig. 3 is emanant grid schematic diagram.

Fig. 4 is a formula grid schematic diagram anyhow.

Of the present utility model according to as follows: pole plate is the parts of lead accumulator electrochemical reaction, is to realize storage battery electric energy and the chemical energy critical component of conversion mutually.The quality quality of pole plate is determining the size of storage battery energy, and grid is the skeleton of pole plate, and it at first can make active electrolyte make moulding, and does not come off because of stressed; Another effect of grid is a conduction current, and the electric current of storage battery is at first to pass through grid, conducts the current to external circuit through the plate ear again.For starting current is exactly the electric weight that stores in starting is at first emitted near near the pole plate the lug moment, is following the natural law from the close-by examples to those far off to conduct in proper order then; The 3rd effect of grid is to make CURRENT DISTRIBUTION even, prevents pole plate buckling deformation in the charge and discharge process.Hence one can see that, and the performance structure of grid can directly influence the performance of lead accumulator.Traditional grid, its rib adopt layout (Fig. 4) anyhow, so that easy to process.People had designed emanant grid (Fig. 3) in order to improve the uniformity of conduction current in the grid afterwards, in order to improve the quality, had occurred hauling type grid (Fig. 2) again.The utility model reduces resistance in order to improve starting current, on the basis of emanant grid, has designed the ridge and blage type grid.Its lug is near the grid center line, and with near the grid area the increase lug, the rib of ridge and blage type grid becomes vein type, and afflux master muscle leads directly to lug, and chap from bottom to top, and resistance is reduced, thereby the electric current that sparks is strengthened; Because grid of the present utility model is lead, calcium, tin, aluminium alloy and cathode absorption type process and the high-efficiency seal structure that adopts high hydrogen overpotential, and this storage battery need not safeguarded; In addition, the utility model has also adopted liquid storage type structure, replaces the external lean solution type structure of introducing, the problem that has solved battery and lost efficacy in advance because of lack of water.

Ridge and blage type grid of the present utility model can be used for various open types or enclosed accumulator.

Attached according to accompanying drawing, the utility model comprises battery case 1, it is a cuboid housing made from engineering plastics, the bottom is separated into six liquid storage tanks 13 with dividing plate 15, battery cover 9 is arranged at top, and battery cover 9 is rectangular two labyrinth seal structures that become with battery case 1 binding site all around, with fluid sealant 2 bondings, six valve control safety caps 5 are arranged at the middle part of battery cover 9, and seal valve gland 4 and top sealing plate 3 are arranged on the safety cap 5.On battery cover 9, also have+,-utmost point binding post 7, its place of picking out seals with fluid sealant 8 and sealing ring 6.Fill in regular turn with the good grid 11 of glass mat 10 parcels in the inside of battery case 1, the leaf shape of 11 one-tenth ridges of grid is filled active material 14, and a plurality of lugs 16 in its top join with connecting plate 12 respectively, are connected to binding post 7.There is supporter 17 that grid is held up in the bottom of grid 11, the diagonal bar on the grid 11 and the angle of main muscle are 25 °-75 °, each bar muscle is thin down to be gone up slightly, its tip degree be 0 °-1 ° 30 ', thickness is equal to or slightly lower than the 0.01-0.4mm of slab lattice thickness, diagonal bar spacing 5-15mm, its transverse bar spacing are 3-10mm, and the transverse shape of muscle is ellipse, circle and rhombus, trapezoidal, triangle.

According to calculating, the electric weight big approximately 40% that the pole plate that the utility model is made than various grids in the past can be emitted.According to the GB 5008.1-91 regulation that international standard IEC95-1 (1988) formulates, the starting battery of 60Ah, its starting current is 240A, as changes the ridge and blage type grid into, then can reach 336A.Therefore, lead-acid battery is employed in rising of a 60Ah, use the ridge and blage type grid instead after, can use as the 90Ah battery.
