A hydraulic gate for flood control of a dam

Abstract

The invention discloses a hydraulic gate for flood control of a dam, comprising a gate body and a door frame, the gate body is slidably connected in the door frame, the left and right sides of the door frame are fixedly connected with a hollow plate, and the upper end of the hollow plate is fixed Connected with risers. Through the expansion and contraction of the hydraulic cylinder on the toothed plate, the gate body is driven to slide up and down in the door frame, so as to realize stable opening and closing of the gate. With the setting of the transmission mechanism, the third gear is driven to rotate by the second motor arranged on the horizontal plate. The disk and the horizontal plate are connected in rotation, the rotation of the third gear is linked to the rotation of the toothed plate, and the upper end of the gate body is connected with the boom for rotation. When the hydraulic cylinder pushes the gate body upward, the toothed plate rotates 90 degrees, The top plate on the upper end of the hydraulic cylinder connected with the boom can enter the placement groove on the pressure column, and the placement groove is used as the second protection project of the top plate, so as to avoid a lot of equipment damage after the hydraulic cylinder is out of control.

Description

technical field [0001] The invention relates to the field of water conservancy engineering equipment, in particular to a hydraulic gate for flood control of dams. Background technique [0002] Hydraulic gate hydraulic system is a professional accessory product, which consists of separate hydraulic jack and oil pump station. It has the characteristics of simple structure, convenient maintenance, light weight, and can be used in any direction, and can be operated from a long distance. There are two forms of gate opening and closing, one is manual operation, the manual operation is to complete the opening and closing of the gate through the rack and pinion; the other is hydraulic operation, which provides pressure to the oil cylinder through the external pump station, and the oil cylinder and the gate are connected. Together, complete the opening and closing of the gate. [0003] However, the traditional hydraulic gate has a single function. When the gate is simply lifted and...

Problems solved by technology

[0003] However, the traditional hydraulic gate has a single function. When the gate is simply raised and supported by the hydraulic cylinder, once the hydraulic cylinder fails, it will cause a lot of damage to the gate frame and the door light facilities.
