Fabricated culvert gate for water conservancy project

Abstract

The invention relates to a fabricated culvert gate for a water conservancy project. The fabricated culvert gate comprises a gate plate, a first mounting groove formed in the upper surface of the gateplate and a water baffle arranged in the first mounting groove, wherein a driving assembly is arranged on the gate plate; a first drainage through hole is formed in the side wall of the side, close tothe upstream of water flow, of the gate plate; a second drainage through hole is formed in the side wall of the side, close to the downstream of the water flow, of the gate plate; the second drainagethrough hole and the first drainage through hole communicate with the first mounting groove; the height of the inner bottom wall of the first drainage through hole is larger than or equal to that ofthe inner bottom wall of the first mounting groove; and the height of the inner bottom wall of the second drainage through hole is smaller than or equal to that of the inner bottom wall of the first mounting groove. According to the fabricated culvert gate, during flood discharge, due to the fact that the height of the inner bottom wall of the second drainage through hole is smaller than or equalto that of the inner bottom wall of the first mounting groove, the probability that impurities in the water flow are left on the inner bottom wall of the first mounting groove is decreased, thus, thebottom face of the water baffle can be attached to the inner bottom wall of the first mounting groove conveniently, and the culvert gate can play a good water storage function conveniently.

Description

technical field

[0001] The present application relates to the technical field of culvert gates, in particular to an assembled culvert gate for water conservancy projects. Background technique

[0002] Culvert gates are indispensable water-blocking and water-stopping equipment in water conservancy and hydropower projects. They can not only be used to regulate the water flow of dams, but also can be used in occasions where the sealing requirements are not too high in urban water supply and drainage and sewage treatment projects, but their characteristics are generally Open and close for still water.

[0003] The Chinese patent with the notification number CN208857785U of the related technology discloses a lift-type water conservancy gate, which includes a gate and a gate frame. The inner upper end of the gate is equipped with an adjustment device, the inner upper end of the adjustment device is fixedly installed with a fixed rod, the top of the upper end of the fixed rod is f...
