Accompanying drawing explanation
Fig. 1 is the overall schematic of an embodiment of the battery cap of storage battery of the present invention;
The overall schematic of the embodiment that Fig. 2 is the battery cap shown in Fig. 1;
Fig. 3 is the schematic top plan view of the taper baffler shown in Fig. 2.
Embodiment
In order to make the object of storage battery of the present invention, technical scheme and advantage clearly understand, below in conjunction with concrete drawings and the specific embodiments, the present invention is further elaborated.
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
See Fig. 1 and Fig. 2, the invention provides a kind of storage battery, comprise the battery cap 100 of battery case (not shown) and the described battery case of covering, described battery cap comprises the first lid 110 and the second lid 120, described first lid 110 covers described battery case, described second lid 120 is positioned at the top of described first lid 110, is also provided with exhausting box 200 in the both sides of described second lid.Please with further reference to Fig. 2, between described second lid 120 and described first lid 110, be provided with the taper baffler 130 be fixed on described second lid 120; Described first lid 110 is provided with return port 111, and the projection of described baffler 130 on described first lid 110 covers described return port 111.Described baffler entirety is in taper, and the summit O of described taper baffler is near described first lid.
The first lid clad battery groove in the present embodiment, when there being the electrolysis tank of multiple accommodation electrolyte in battery case, first lid can arrange the whole battery case of as a whole covering, second lid also arranges as a whole, the area of the second lid can be less than the area of the first lid simultaneously, as long as the second lid can cover all return ports of the first lid.Storage battery is using and is filling, have heat in discharge process to produce, moisture in electrolyte is heated and can becomes steam, these water vapours discharge the space entered between the first lid and the second lid from the return port of the first lid, the present invention is provided with taper baffler between the first lid and the second lid, therefore water vapour can flow along the surface of taper baffler, due to the existence of taper baffler, delay the rate of climb of water vapour, add the stroke of water vapour, thus make part water vapour flow into battery case by return port after the condense on surfaces of taper baffler becomes water droplet, thus reduce the loss speed of water in electrolyte, after proving to add baffler by experiment, the useful life of storage battery on average improves 7%.。
Further, the present embodiment limits taper baffler entirety in coniform, arranges the flowing of more convenient condensate like this.
See Fig. 2, the distance between the summit of described taper baffler 130 and described first lid 110 is 5mm to 20mm.It should be noted that, in the present embodiment, the summit of taper baffler can be positioned at the top of the first lid, also can be positioned at the below of the first lid.

In another embodiment, the summit of described taper baffler 130 is positioned at the inside of described battery case, and there is prepsetting gap between described taper baffler 130 and the liquid level of described battery case.Now, taper baffle portion is positioned at the top of the first lid, and the summit of another part especially taper baffler is positioned at the below of the first lid.Such setting can better water conservancy diversion water vapour.In the present embodiment, the summit of taper baffler can not contact the liquid level of electrolyte.
When the below of summit first lid of taper baffler (summit of taper baffler is arranged in battery case), between described taper baffler and described return port, there is prepsetting gap.That is taper baffler does not contact with return port.Preferably, the diameter in the cross section of described taper baffler on described first lid and the diameter ratio of described return port are 1:1.2 ~ 1.8.
Further, the projection of summit on described first lid 110 of described taper baffler 130 is arranged in described return port.
Further, described taper baffler 130 is also provided with leaking hole 131, the projection of described leaking hole 131 on described first lid 110 is arranged in described return port.Such setting is that the condensate of the inner surface near the second lid of baffler is back in battery case.
Preferably, see Fig. 3, described leaking hole is positioned at the summit of described baffler 130.
As one preferably execution mode, the part surface of the close return port 111 of described first lid 110 is to the centroclinal setting of described return port.The condensate arranging the surface being conveniently dropped in the first lid is like this back in battery case.
In another embodiment, in described battery case, be provided with the electrolysis tank of multiple accommodation cell liquid, the return port that described first lid is provided with and described electrolysis tank one_to_one corresponding, described taper baffler and described return port one_to_one corresponding.As shown in Figure 1, in battery case, be provided with 6 electrolysis tanks, be provided with 6 return ports and 6 taper bafflers accordingly.
More excellent, the second lid in the present embodiment and taper baffler can be one-body molded.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claim.
