Abstract

The invention discloses a hinge dam, and belongs to the field of water blocking equipment. The hinge dam comprises a foundation, a dam face, a hydraulic driving mechanism and a base, wherein the base is fixed on the foundation, and a hollow bottom shaft hinged to the base is arranged on the bottom end of the dam face; and a containing cavity is formed in the land side of the dam face. The hydraulic driving mechanism comprises a hydraulic cylinder, a hydraulic unit, a sealing oil tank and a sealing control box, wherein the bottom end of the hydraulic cylinder is hinged to the base, and the top end of the hydraulic cylinder is hinged to the land side of the dam face; the hydraulic unit is connected with the hydraulic cylinder through a hydraulic line; the sealing oil tank is connected with the hydraulic unit though an oil line; the sealing control box is connected with the hydraulic unit through control cables; the hydraulic line, the hydraulic unit, the oil line, the sealing oil tank and the sealing control box are all fixed in the containing cavity; and the control cables penetrate out of the wall of the hollow bottom shaft to be connected with the sealing control box. According to the hinge dam, vibration of the dam face under the condition of dynamic load is effectively avoided, installation construction and later maintenance are convenient, the function that the hinge dam falls for a certain height automatically when any position stores water and is overloaded is achieved, and accordingly the situation that the dam or the dam face is destroyed by rush of water due to an over-large water overflowing height is avoided.

Description

technical field [0001] The invention relates to the field of waterproof facilities, in particular to a hinge dam. Background technique [0002] Dams with steel structures or reinforced concrete structures are often used in water conservancy projects for water blocking operations. Common water blocking slabs generally include flap dams, steel gates, hydraulic lift dams, etc. Taking the hydraulic lifting dam as an example, the bottom edge of the dam is hinged on the foundation through the hinge shaft, and a hydraulic drive mechanism is set on the backwater side of the dam surface to drive the dam surface up and down, so it is also called a hinge dam. reliability and durability. It can be seen that it is very necessary to provide a hinge dam. [0003] The prior art provides such a hinged dam, which includes a dam surface, the bottom edge of which is hinged on the foundation through a hinge shaft, and a hydraulic drive mechanism is arranged on the backwater side of the dam sur...
