Description
Technical Field
The utility model relates to the field of lead storage battery manufacturing, in particular to a buckle bottom design for a tubular storage battery, and particularly relates to a buckle bottom for a long-service-life tubular storage battery.
Background
In the lead storage battery series, the tubular storage battery has low specific energy compared with the paste-coated electrode plate battery, but is still used in a large amount in the circulating and floating situations due to its long life. The service life of the tubular storage battery can reach more than 2 years and even higher when the tubular storage battery is recycled by 100% DOD, and the service life of the tubular storage battery can reach more than 15 years when the tubular storage battery is in floating charge operation, which is far higher than that of a lead storage battery manufactured by a paste-coated polar plate, so the requirements on the anti-aging capability and structural design of parts of the tubular storage battery are much higher than those of a coated battery. In the manufacturing process of the tubular polar plate, the positive plate skeleton is produced by adopting a high-pressure die casting or gravity casting mode, the produced skeleton is processed to reach the model specification and size used for production, then the positive plate skeleton is sleeved with the positive plate skeleton, the positive plate is filled with living matters by adopting a powder filling, paste squeezing or grouting mode, then the plastic button bottom is buckled, and the positive plate is formed by pickling (or water spraying) solidification and drying. The used buckle bottom is made of plastic materials, and has two functions, namely, the active material is reserved in the calandria, and the buckle bottom is well connected with the polar plate into a whole, so that the lower connection is stable. At present, in order to better keep active substances in the calandria, the adopted design is that the outer diameter of the buckle bottom is the same as the outer diameter of the calandria in size, so that sealing is realized. On the other hand, in order to prevent the button bottom from being separated from the calandria (or skeleton) in the service life of the battery, the adopted closing mode of the button bottom is realized by interference fit between the button bottom and the calandria wall, namely, the button bottom is designed into an inverted eight-wing structure, so that the wing end size of the button bottom is larger than the inner diameter of the calandria, and the button bottom is connected with the calandria. More specifically, the patent with publication number CN105958082a discloses a buckle bottom of a tubular storage battery, which comprises a base for connecting a frame of the tubular storage battery and a plurality of joints for extending into a calandria of the tubular storage battery, barbs are arranged on two sides of the top end of the joint, tips of the barbs face the base, and the distance between two barb tips of the same joint is larger than the diameter of the calandria. Although the button bottom can prevent loosening and falling, so that the defects of micro short circuit or capacity attenuation and the like caused by powder falling are reduced, the calandria has no problem under the condition of short service life of the battery, but the long-term stress concentration at the contact part of the button bottom 'inverted eight wings' and the calandria and the ageing of the calandria can cause the ageing speed of the calandria to be obviously higher than that of other parts to damage the calandria, so that the calandria is broken, thereby influencing the performance of the battery.
