Description

Storage battery

The utility model relates to a kind of storage battery, the battery cap that it has on the salable what accumulator body, and when being used for promoting the unobstructed property of exhaust of accumulator body and preventing that storage battery from toppling over, inner each the little tank house registry with one another of accumulator body.

As shown in Figure 1, storage battery in the past comprises that one is used for being installed in the accumulator body 1 of electrolyte and battery lead plate, and one corresponding lid be located at lid 2 on the body 1, not shown electrolyte and battery lead plate, accumulator body 1 has an opening and be the rectangle tank house 11 of permeable type up, tank house 11 mat multi-disc dividing plate 12 again separates to not being communicated with each other and the little tank house 13 of linearly arrangement, can be installed in electrolyte and battery lead plate in the little tank house 13, lid 2 has a room 21 corresponding with tank house 13, be provided with in the room 21 multi-disc can with the partition 22 of dividing plate 12 corresponding windings, partition 22 is that room 21 is separated into a plurality of corresponding with little tank house 13 respectively small chamber 23, all be provided with a short slot 24 on each partition 22, when lid 2 lids are established on the what body 1, each little tank house 13 is communicated with short slot 24 with small chamber 23 relative merging, in addition, for being connect, establishes by battery lead plate in power supply and the accumulator body 1,2 liang of corresponding corners of lid are respectively equipped with the window 26 that a power supply source circuit stretches through again, after accumulator body 1 and lid 2 windings were finished, two windows 26 were to be air-tight state after being stretched through by power circuit.

Cooperate shown in Figure 2, lid 2 tops are provided with a fluid injection that deviates from mutually with room 21 interval 25 and in abutting connection with between the other exhaust area of interval 25 sides of what fluid injection 26, on fluid injection interval 25, be provided with a plurality of corresponding mutually with these small chamber 23 respectively, so that can pour into the liquid injection pipe 251 in the little tank house 13 of electrolyte what, 26 liang of respective side are respectively equipped with an air discharge duct 261 between exhaust area, and the middle section is provided with a blast pipe 262, blast pipe 262 ends are provided with two profile grooves 263 and correspondence is arranged with a pressure cap 264, be covered with a seal cover 27 with the high frequency heat-sealing again on 26 between exhaust area, after covering between the what exhaust area 26, seal cover 27 forms a gap between meeting and exhaust area between 26, during use, the gas that produces because of cell reaction in each little tank house 13 can be compiled in the what blast pipe 262 and formed an air pressure with pressure cap 264 pushing tow up by short slot 24, so that discharged by air discharge duct 261 from two profile grooves 263, gap of 26 through between seal cover 27 and exhaust area.

After lid 2 lids of storage battery are established on the what accumulator body 1, on the one hand for preventing that the electrolyte in the accumulator body 1 from overflowing, must have good sealing property, on the other hand, for the gas that provides accumulator body 1 internal cause cell reaction to produce has a pipeline of suitably discharging, must have degassing function, therefore, lid 2 must possess the function of good antiseepage water-based and good exhaust effect, but, the gas that lid 2 has only a blast pipe 262 to connect to draw each little tank house 13 internal cause electrolysis to produce, exhaust is difficult for, and, after lid 2 covers on the what accumulator body 1, though have certain anti-seepage effect, the electrolyte that can prevent tank house interior 11 oozes out, but, as Fig. 2, shown in 3, because be equipped with a short slot 24 on each partition 22, short slot 24 mainly provides this blast pipe 262 of gas flow in each little tank house 13, this design does not have any bad situation and produces when storage battery is steady placement, but, when storage battery place what rocks state, for example transport in the process of carrying, or when toppling over accidentally, short slot 24 may cause the electrolyte in each little tank house 13 to circulate each other via short slot 24, shown in the arrow among Fig. 3, and it is unequal to cause electrolyte to distribute, and each little tank house 13 balance is to each other gone to pot and influences the electric power storage effect.
