Description
Technical Field
The utility model relates to a lead acid battery field, concretely relates to large capacity lead acid battery.
Background
Normal lead storage batteries form lead sulfate crystals when discharged and are relatively easily reduced to lead when charged. If the battery is used and maintained poorly, such as by frequent undercharging or overdischarging, a coarse hard lead sulfate develops on the negative electrode. This lead sulfate is difficult to reduce by conventional charging methods, requires a high charging voltage, and generates a large amount of gas due to poor charge acceptance during charging. This phenomenon, which usually occurs at the negative electrode, is called irreversible sulfation. It causes a drop in the capacity of the battery and even causes the end of the life of the battery. Therefore, when stored for a long period of time or over-discharged, a large amount of lead sulfate exists, and the individual lead sulfate crystals grow by adhering to the dissolution of small crystals, together with the fluctuation in the sulfuric acid concentration and temperature. Slight vulcanization of the battery can reduce the capacity of the battery, increase the internal resistance of the battery, and fail the electrode and can not be charged when the internal resistance of the battery is serious. When the circuit needs to be maintained, the locking bolt of the wire clamp on the negative pole is generally rusted, and the wire clamp on the negative pole is generally required to be pried down by a screwdriver.

Detailed Description
As shown in figures 1-4, a large capacity lead-acid battery comprises a battery body 1, a first groove 2 is provided on an end cover of the battery body 1, a negative electrode post 7 of the battery body 1 penetrates through the first groove 2, a ring groove 3 is provided on a groove wall of the first groove 2, a clamping plate 4 is clamped in the ring groove 3, the clamping plate 4 is a stainless steel plate, a second groove 5 is provided on the clamping plate 4, the negative electrode post of the battery body 1 penetrates through the second groove 5, fixing plates 6 are fixed on the clamping plate 4 at the front and rear sides of the second groove 5, the upper parts of the two fixing plates 6 are bent at 90 degrees relatively to form a bent part, a chute 8 is provided on the position of the negative electrode post 7 of the battery body 1 corresponding to the bent part, the bent part is slidably clamped in the chute 8 at one side of the bent part, a third groove 9 is provided on the upper end of the negative electrode post 7 of the battery body 1, the, the upper cover of the cathode pole 7 is provided with a cap 11, the cap 11 is made of engineering plastics, a line pressing column 10 is fixed in the cap 11, the line pressing column 10 is located in a third groove 9, the bottom of the third groove 9 is a cambered surface, the lower end face of the line pressing column 10 is a cambered surface, a vertical bolt 12 is in threaded connection with one side of the cap 11, and the lower end of the bolt 12 is rotatably connected with the clamping plate 4.
When needs are worked a telephone switchboard to negative terminal 7, with cardboard 4 card in spout 8, negative terminal 7 runs through second recess 5 this moment, and the kink of cardboard 4 upper fixed plate 6 is located inside spout 8, puts into the third recess 9 with the electric core of electric wire in, then twists bolt 12 for 11 covers of block are established in negative terminal 7 upper end, and line ball post 10 in the block 11 is located third recess 9 and is compressed tightly by the electric wire electricity core in the third recess 9 and fix inside.
When the electric wire on the cathode post 7 needs to be replaced, the bolt 12 is screwed, the bolt 12 enables the cap 11 to move upwards, because the wire pressing column 10 is located in the third groove 9, the upper end of the third groove 9 expands towards the outer side direction of the cathode post 7, when the cap 11 moves upwards, the wire pressing column 10 can be more easily withdrawn from the third groove 9, the wire pressing column 10 is prevented from being blocked by lead sulfate crystals, meanwhile, when the bolt 12 is screwed to enable the cap 11 to move upwards, the bolt 12 acts on the clamping plate 4, the contact area between the clamping plate 4 and the cover body of the battery body 1 is larger, when the bolt 12 is screwed to enable the cap 11 to move upwards, the stress area of the cover body of the battery body 1 can be increased, and the cover body of the battery body 1 can be prevented from being damaged due to overlarge stress.
