A Plane Double Section Emergency Gate Favorable for Dynamic Water Closing

Abstract

The invention discloses a planar double-section emergency gate easy to close in flowing water. The planar double-section emergency gate is arranged in an emergency gate slot through a sliding supporttype, the two sides of the front of the emergency gate slot are side walls of a flow passage of a water inlet, the bottom of the emergency gate slot is provided with a water inlet flow passage bottomplate, the top of the emergency gate is provided with a lifting lug, the two sides of the lifting lug are provided with sliding blocks supporting the emergency gate to slide in the gate slot, the emergency gate comprises an upper half-section gate and a lower half-section gate composed of a gate page longitudinal beam and a gate page transverse beam, the upper half-section gate is provided with afirst upstream panel, the lower half-section gate is provided with a downstream panel and a second upstream panel, the upper half-section gate and the lower half-section gate are connected through a steel wire rope, and a baffle is arranged between the upper half-section gate and the lower half-section gate. The planar double-section emergency gate easy to close in the flowing water has the advantages that the water column pressure can be utilized more fully during gate closing in the flowing water to overcome the frictional resistance, thereby achieving smooth closing of the gate.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering steel structures, and in particular relates to a new type of body that is conducive to the smooth closing of a sliding support plane double-section accident gate in moving water, and mainly solves the problem of the plane accident gate that uses water to close the door due to the closing force in moving water. Insufficient practical engineering problems that fall into place. Background technique [0002] The gate is the active water retaining structure in the hydraulic structure. Use it to close, open or partially open the water orifice to control the water level, regulate the flow, etc. Therefore, the safety and stability of the gate is of great significance to the normal operation of the water conservancy project. Flat gates have been widely used in water conservancy projects because of their simple structure, light use, convenient maintenance, low price, low require...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a plane double-section accident gate which is beneficial to dynamic water closing, to solve the problem that the self-weight and water weight of the accident gate are not enough to overcome the friction during the dynamic water closing process. Practical engineering problems such as closed door jamming and gate not falling in place caused by resistance
