Description

Technical Field

[0001] The invention relates to the field of hydraulic dams, and more specifically to a side water-stop structure for a bottom horizontal axis rotating steel dam gate. Background Art

[0002] With the needs of water conservancy and hydropower project construction, urban water use, landscape construction, environmental improvement, and agricultural irrigation, steel dam gates have been widely used. Bottom horizontal axis rotating steel dam gates are a common type of gates. The gates are raised and lowered by driving the bottom horizontal axis to rotate, thereby achieving the purpose of water blocking or water discharge.

[0003] In order to avoid water leakage on both sides of the bottom horizontal axis rotating steel dam gate in the prior art, sealing components are usually set on both sides of the gate to achieve the purpose of side water stopping. The existing gate side water stopping sealing components generally use rubber strips. Since the rubber strips and the wall are always in a friction state during the gate flipping process, the large friction resistance makes it difficult to flip the gate, affecting the gate flipping speed. Frequent friction will cause serious wear of the rubber strips, affecting its sealing performance and causing the water stopping effect to deteriorate. If things go on like this for a long time, tearing will occur. If it is not replaced in time, the side water stopping will fail. Summary of the invention
