Automatic opening and closing type gate for water conservancy project construction

Abstract

The invention belongs to the technical field of water conservancy projects, and discloses an automatic opening and closing type gate for water conservancy project construction, which comprises a door frame, a gate body, a hydraulic mechanism and an arc-shaped rod, the output end of the hydraulic mechanism is hinged with one connecting end of the arc-shaped rod, the other end of the arc-shaped rod is fixedly connected with the bottom of the gate body, and the gate body is movably installed on the inner side of the door frame and can rotate around the top end of the gate body. By starting a hydraulic rod and driving a transmission toothed rod to move, a rectangular rotating door is driven to rotate integrally, a connecting column relieves closing limitation on a hollow groove of the gate body, so that water can be drained by opening a channel, similarly, the front water pressure of the gate body is higher due to larger area, after the rectangular rotating door is opened, the front surface area of the gate body is greatly reduced, so that the borne water pressure is also greatly reduced, the transmission load is reduced, and the loss of the gate and a transmission mechanism caused by higher water pressure is reduced.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, in particular to an automatic opening and closing gate for water conservancy engineering construction. Background technique [0002] The gate is a door used to close or open the drainage channel in the construction of water conservancy projects. It is one of the indispensable hydraulic structures in water conservancy projects. Through the ingenious application of the gates, many accidents of intercepting water flow and waterproofing can be realized. Other functions include controlling water level, regulating flow, and even protecting the environment. [0003] Existing automatic opening and closing gate designs, such as traditional gates, require a power source to cooperate with a transmission mechanism to lift the gate as a whole, or control its rotation to open, when the traditional gate is waterproofed. The water pressure on the front will be very large. At this time, it ...

AI Technical Summary

Problems solved by technology

[0003]Existing designs of automatic opening and closing gates, such as traditional gates, require a power source to cooperate with a transmission mechanism to lift the gate as a whole, or control It rotates to open, and the upstream water level is usually high when the gate is opened, so the water pressure on the front of the gate will be very large. The loss of the transmission mechanism is very large, so the maintenance cycle of this kind of gate is short, the object of maintenance is larger and heavier each time, and the maintenance work will be more difficult, and some gates are non-detachable, making maintenance more difficult. Therefore, we There is an urgent need for a new valve that can be opened with a small load at a higher water level, thereby reducing gate loss and reducing its maintenance frequency
