Positive grid for AGM type deep cycle battery

The utility model relates to the technical field of storage batteries, and particularly discloses a positive grid for an AGM type deep circulation battery, which comprises a frame, an upper rib group, a lower rib group and a middle rib group, the upper rib group comprises first transverse ribs and first vertical ribs, the lower rib group comprises second transverse ribs and second vertical ribs, and the number of the first vertical ribs is larger than that of the second vertical ribs; the middle rib set comprises first inclined ribs and second inclined ribs, and the first inclined ribs and the second inclined ribs are sequentially connected end to end between the lowest first transverse rib and the uppermost second transverse rib to form a triangular mesh structure. The ribs in the frame of the positive grid are divided into the upper rib group, the middle rib group and the lower rib group, the number of the first vertical ribs is increased, the reaction area is increased, the current of the anodic oxidation
