A plane accident gate

Abstract

The invention discloses a planar emergency gate which adopts a slide supporting type and is mounted at a gate slot of the emergency gate; water inlet runner side walls are arranged at the two sides infront of the gate slot of the emergency gate; the bottom of the gate slot of the emergency gate is equipped with a water inlet runner bottom plate; the emergency gate comprises an upstream panel anda downstream panel which are arranged at front and rear sides; a gate sheet longitudinal beam and a gate sheet transverse beam are arranged between the upstream panel and the downstream panel; crossedjoint positions of front and rear panels are mutually connected through a connecting beam; a lifting lug is arranged on the top of the emergency gate; slide blocks for supporting the emergency gate to slide up and down in the gate slot are arranged at the two sides of the lifting lug; the bottom of the upstream panel is fixedly connected with a front edge plate block which is parallel to the water inlet runner bottom plate; the front edge of the front edge plate block is equipped with a bump which is in contact with the water inlet runner bottom plate; and a reinforcing rib plate is fixedly connected between the front end of the front edge plate block and the upstream panel. Vertical water pressure borne on the planar emergency gate which is closed by utilizing water gravity is increased,so that the gate is promoted to be smoothly closed.

Description

technical field [0001] The invention belongs to the field of steel structures of water conservancy and hydropower projects, and in particular relates to a plane accident gate; a new shape that is beneficial to the smooth closing of the sliding support plane accident gate in moving water, and solves the problem of closing the plane accident gate in moving water due to water weight. Practical engineering problems that are not in place because of insufficient strength. Background technique [0002] With the construction of high reservoir dams, plane gates are more and more widely used in water conservancy projects as emergency gates because of their simple structure, convenient and reliable operation, and easy coordination with the layout of buildings. However, due to the influence of high water head and large discharge flow, whether the flat emergency gate can be closed normally in moving water and its hydrodynamic characteristics during the closing process have always been th...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a plane emergency gate which can promote the smooth closing of the gate by further increasing the vertical water pressure on the plane emergency gate closed by water weight in moving water; It is used to solve practical engineering problems such as closed door jamming and gate not falling in place due to self-weight and water weight not enough to overcome friction during the closing process of the accident gate.
