Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition carries out improving to prior art and improves, provides and the pregnant solution type of the lasting anti-acid flame-proof of resistance to inclination can start lead acid accumulator, to reach the object of raising storage battery safety in utilization.For this reason, the present invention takes following technical scheme.
Can the lasting anti-acid flame-proof of resistance to inclination pregnant solution type start lead acid accumulator, comprise storage battery, be coated at the casing of storage battery, the upper cover matched with casing, cover on described and be provided with multiple liquid injection port, it is characterized in that: described liquid injection port is provided with anti-overflow assembly, described anti-overflow assembly comprises anti-overflow pipe, be located at the anti-explosion acid-filtering plate on anti-overflow pipe top, be positioned at the ventilation tegillum above anti-explosion acid-filtering plate, be positioned at the sealing gasket of anti-overflow pipe bottom, steam vent is provided with in the middle part of described ventilation tegillum, anti-overflow tube cavity forms fluid chamber, connecting portion is established in anti-overflow pipe bottom, connecting portion is connected with the liquid injection port of upper cover, described sealing gasket is between anti-overflow pipe and upper cover.Be hollow due to anti-overflow pipe inside and have a height, if when pregnant solution type start lead acid accumulator tilt to use in practical matter time, flowing electrolyte in cell negative terminal can be held completely.
As improving further and supplementing technique scheme, the present invention also comprises following additional technical feature.
Described connecting portion is provided with external screw thread, and anti-overflow pipe is threaded with liquid injection port.Anti-overflow pipe and upper cover easy to connect, reliably.
Anti-overflow pipe hypomere external diameter is less than epimere and forms downward step surface, and described sealing gasket is between step surface and upper cover top surface.Increase its sealing reliability.
Described anti-explosion acid-filtering plate is fine-meshed anti-explosion acid-filtering plate.Fine-meshed is used for passing through of air, avoids the spilling of electrolyte simultaneously.
The aperture, top of anti-overflow pipe is greater than bottom and forms ventilation tegillum container cavity, and described anti-explosion acid-filtering plate, ventilation tegillum are arranged in ventilation tegillum container cavity, and external diameter and the ventilation tegillum accommodation hole of anti-explosion acid-filtering plate, ventilation tegillum match.Ventilation tegillum, anti-explosion acid-filtering plate and anti-overflow pipe interference fit, or adopt bonding way to connect.
Described ventilation tegillum container cavity establishes up big and down small tapering.If tapering can improve the compactness of cooperation, electrolyte is avoided to reveal from the periphery of anti-explosion acid-filtering plate and ventilation tegillum.
The height of anti-overflow pipe is 1/4 ~ 3/4 of box height.
Beneficial effect: due to anti-overflow pipe inside be hollow and have one height, if when pregnant solution type starts lead acid accumulator in practical matter inclination use, can hold flowing electrolyte in cell negative terminal completely, the technical program effectively solves the seepage that pregnant solution type starts lead acid accumulator, prevent from the generation of acid mist in charging process and meet naked light setting off an explosion, stop potential safety hazard, drastically increase battery capacity and life-span.
