Fully-enclosed steel dam gate

Abstract

The invention discloses a fully-enclosed steel dam gate. The fully-enclosed steel dam gate comprises a bottom transverse shaft, a steel dam door leaf and a hoist arranged in a gate chamber; the two ends of the bottom transverse shaft penetrate through the wall of the gate chamber to connect the hoist, and the bottom transverse shaft is driven to rotate by the hoist; the steel dam door leaf is connected with the bottom transverse shaft to form a gate; a sealing component is arranged at the position where the side of the steel dam door leaf is contacted with the wall of the gate chamber; the sealing component comprises a fixed seat and a sealing adhesive tape; the fixed seat is arranged on the side of the steel dam door leaf; the sealing adhesive tape is arranged at the outer end of the fixed seat and is closely pressed against the wall of the gate chamber; meanwhile, a spring or a spring oil cylinder is also arranged on the fixed seat to jack the sealing adhesive tape so that the sealing adhesive tape is in interference fit with the wall of the gate chamber; two Y-shaped sealing rings are respectively arranged at the positions, penetrating through the wall of the gate chamber, of the two ends of the bottom transverse shaft in parallel. By the fully-enclosed steel dam gate, a good sealing effect of the steel dam gate also can be guaranteed when the bottom transverse shaft is deviated or the wall of the gate chamber is not flat.

Description

[0001] technical field [0002] The invention belongs to large-scale water conservancy and hydroelectric machinery equipment, in particular to a steel dam gate. Background technique [0003] Hydraulic steel dam gates are common mechanical equipment in water conservancy and hydropower projects. Generally, there is a sealing strip between the steel dam gate and the lock chamber, but because the lock chamber wall cannot be completely flat, the seal between the gate and the lock chamber wall may not be reliable when rotating Water leakage occurs, and the seal of the rotating shaft passing through the wall of the lock chamber is usually filled with cover plates at both ends of the wall, and the cover plate is connected with the sleeve on the rotating shaft to form a seal. However, the rotating shaft may be deflected during work. At this time, there will be a tiny gap between the cover plate and the shaft sleeve, which will cause water leakage.
