High-strength and high-sealing-performance hydraulic dam

Abstract

The invention discloses a high-strength and high-sealing-performance hydraulic dam. A step-type base is provided with a plurality of rotating shafts and P-shaped water stopping strips, four rotating-shaft pressing plates are evenly arranged at the portions, on the backwater sides of the rotating shafts, on the step-type base, the rotating-shaft pressing plates are provided with arc concave faces respectively, the rotating shafts are provided with wedge-shaped dam bodies, and transverse reinforcing ribs, longitudinal reinforcing ribs and two sets of opposite dam-body lug plates are arranged on the back faces of the wedge-shaped dam bodies; base lug plates corresponding to the dam-body lug plates, upper supporting arms and lower supporting arms are arranged on the step-type base, wherein the upper supporting arms and the lower supporting arms are arranged between the dam-body lug plates and the base lug plates; positioning rods are also arranged between the lower supporting arms below connecting shafts, the lower supporting arms are movably connected with the base lug plates through lower-supporting-arm pin shafts, hydraulic oil cylinders are aslant arranged in the step-type base, and the hydraulic oil cylinders and the positioning rods are of reverse-Y-shaped support structures. The high-strength and high-sealing-performance hydraulic dam is simple in structure and high in structure intensifying, all structural pieces are compactly matched, and the anti-water-penetration performance is excellent. In the severe environment, it can be achieved that a hydraulic retaining dam is used in a long-service-life mode.

Description

technical field [0001] The invention relates to water conservancy facilities, in particular to a hydraulic dam with high strength and high sealing performance. Background technique [0002] Hydraulic dams are widely used in water conservancy projects. The existing hydraulic dams have the following disadvantages: 1. The gap between the rotating shaft and the hinge support is large, uneven, and the bottom of the dam shaft has poor water sealing performance; 2. Water leakage is easy between adjacent rotating shafts 1. It is difficult to maintain, which is a difficulty that has not been overcome in this field; 3. The dam body is fixed on the base by the rotating shaft and two hinge supports, so there are few stress points, stress concentration, potential safety hazards, and it is not easy to disassemble and maintain; 4. The support rod of the existing hydraulic dam is relatively long, and it is easily blocked by sundries when opening and closing; 5, the support rod is supported ...
