Abstract
The utility model discloses a through-wall water seal device for a bottom shaft driving steel dam gate and belongs to the technical field of steel dam gates. The through-wall water seal device for the bottom shaft driving steel dam gate comprises a through-wall sleeve fixed to a wall. A bottom shaft pipe penetrates through the through-wall sleeve. One side of the wall is a water facing side and the other side of the wall is a water back side. The bottom shaft pipe is sleeved with an outer bush and an inner bush. The outer bush and the inner bush are respectively connected with the through-wall sleeve in a sealed mode. The outer bush is located on the water back side and the inner bush is located on the water facing side. The inner side of the outer bush and the inner side of the inner bush are provided with inner steps radially protruding inwards respectively. A gap between the outer bush and the bottom shaft pipe is filled with gland packing. An outer gland is arranged outside the outer bush and compresses the gland packing from the water back side to the water facing side. An elastic sealing assembly is arranged in a gap between the inner bush and the bottom shaft pipe. An inner gland is arranged on the side face of the inner bush and compresses the elastic sealing assembly from the water facing side to the water back side. The through-wall water seal device for the bottom shaft driving steel dam gate is simple in structure, good in sealing performance and capable of being applied to a steel gate of a transverse bottom shaft.
