The accumulator plate anti-deformation device
[technical field]
The utility model relates to a kind of device that can prevent the pole plate distortion of lead acid accumulator.
[background technology]
The course of work of lead acid accumulator is its charging and discharging process, in this process since pole plate in lead oxide not the cracked ends chemical change be lead sulfate, cause the density of pole plate constantly to diminish, volume constantly expands.And the assembling of storage battery is compact, its inner pole plate is supported by the shell of storage battery, there is not space more than needed to allow pole plate to expand, therefore, pole plate is subjected to the restriction in space to cause flexural deformation easily in expansion process, simultaneously, battery cover is subjected to influencing its sealing after the top power that pole plate makes progress, thereby influences battery useful life.
China Patent No. is that 0279462.2 utility model patent discloses a kind of solution of the above problems, specifically be that a splayed bracing frame is set below pole plate, the splayed bracing frame is slow bending along with pole plate expands, and is the pole plate elongation and has stayed the space.Its weak point is for holding pole plate and the need that prevent the acid liquid corrosion bracing frame, need dividing plate between splayed bracing frame and the pole plate, use inconvenience, and just there is unstable problem in the Eight characters structure of splayed bracing frame itself.
[utility model content]
The purpose of this utility model provides a kind of pole plate that can prevent is out of shape, and device simple and reliable for structure, easy to use.
The technical solution of the utility model is as follows: storage battery is prevented the pole plate anamorphic attachment for cinemascope, comprises a battery case, is provided with pole plate in the battery case, and a plurality of pole plates constitute utmost point group, is provided with a supporter between battery case bottom and utmost point group.Storage battery is when assembling, only need earlier supporter to be put into battery case, and then the utmost point group that packs into, cushion possesses the intensity that supports utmost point group, in the use of storage battery, pole plate expands needed space by the acquisition of extruding supporter, and the supporter place of being extruded is suitable with the dilatancy of pole plate, and fit with pole plate, make that whole supporting construction is more firm.
Described supporter is a whole cushion.Cushion is monolithic construction, and is easy for installation, and reliable operation.
Described cushion is cuboid, and its bottom has a plurality of deformation grooves.The deformation groove is used to provide utmost point group's deformation space, and the quantity of its setting and position and utmost point group's pole plate adapts.
The bottom of described cushion has the groove vertical with the deformation groove.If it is the cushion of groove is easy to occur bending and deformation at length direction, suitable with the distortion of actual pole plate.
Described cushion is paved with the bottom of entire cell groove, highly is 5 to 10 centimetres.The too high meeting of cushion excessively takes up room, and crosses the low effect that pole plate expands that absorbs that then do not have.
The material of described cushion is a low density foam.Low density foam possesses the intensity that supports utmost point group, and has acid-resistance.
Described supporter adopts acidproof polystyrene material, and density is 0.030-031g/cm
3Polystyrene has stronger acidproof corrosion resistance, effectively absorbs pole plate when the density that supporter is fit to provides support power for utmost point group and expands.
Outstanding advantage of the present utility model is to be provided with a supporter between battery case bottom and the utmost point group, in the use of storage battery, pole plate expands needed space by the acquisition of extruding supporter, the supporter place of being extruded is suitable with the dilatancy of pole plate, fit with pole plate, make total more firm, and adopt monolithic construction, reliable operation, easy to assembly.

[embodiment]
Below in conjunction with accompanying drawing the utility model is done detailed description.
As shown in Figure 1, 2, storage battery is prevented the pole plate anamorphic attachment for cinemascope, comprise a battery case 1, be provided with pole plate 2 in the battery case 1, a plurality of pole plates 2 constitute utmost point group 3, between battery case 1 bottom and utmost point group 3, be provided with a supporter 4, supporter 4 is a whole cushion, cushion is cuboid, its bottom has a plurality of deformation grooves 41 and the groove 42 vertical with deformation groove 41, and supporter 4 is paved with the bottom of entire cell groove, highly is 5 to 10 centimetres, supporter 4 is adopted as acidproof polystyrene low density foam material, and its density is 0.030-031g/cm
