Gate groove with transition structure

Abstract

The invention provides a gate groove with a transition structure. The gate groove is characterized in that the gate groove is divided into a transition section gate groove and a rectangular gate groove from top to bottom in the height direction, the cross section of the transition section gate groove on one side is formed by connecting oblique line sections at the two ends and a straight line section in the middle in a smooth mode, the two oblique line sections are symmetrically arranged, and the distance between the two oblique line sections is gradually increased from outside to inside to form a trapezoidal transition section. The invention discloses the trapezoidal transition section gate groove, and the transition section of the gate groove is in an oblique line shape. The service life of the gate groove is prolonged, and damage to the gate groove is reduced; water flow resistance is reduced, and flow is increased; hydraulic loss is reduced; and operation management of a water gate is greatly facilitated, and certain economic benefits are brought.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a gate groove with a transition structure used in water conservancy engineering. Background technique [0002] Today's water conservancy projects mostly use dams to release and stop water. Gates and gate grooves are needed to waterproof the water flow. Long-term water discharge and water stop will cause the gate to cause certain damage to the inside of the gate groove. Common The rectangular gate slot is easy to form a vortex in the gate slot when passing water, causing damage to the gate slot and reducing the service life of the gate slot. The current form of the gate slot cannot effectively reduce the impact of the water flow on the gate slot, which will cause the gate slot In the case of being washed by water for a long time, the problem of water leakage occurs. [0003] Therefore, it is very important to reasonably analyze and design a gate slot, improv...
