Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: when the staff opens the gate for flood discharge, the sundries in the water flow tend to stay on the inner bottom wall of the gate frame, which is not convenient for the inner bottom wall of the gate frame and the bottom wall of the gate. The bottom wall fits closely, which is not conducive to the gate for water storage

Embodiment Construction

[0033] The following is attached Figure 1-5 The application is described in further detail.

[0034] The embodiment of the present application discloses a prefabricated culvert gate for water conservancy projects. refer to figure 1 The assembled culvert for water conservancy projects includes a gate plate 1, a water retaining plate 2, a sealing assembly 3, a filter assembly 4, and a driving assembly 5. The gate plate 1 is a rectangular steel plate arranged vertically, and the length direction of the gate plate 1 is perpendicular to the water flow direction. , and the side walls on both sides of the gate plate 1 are respectively fixed to the side walls on both sides of the river channel. combine figure 2 As shown, the upper surface of the gate plate 1 is provided with a first installation groove 11, and the side wall of the gate plate 1 close to the upstream side of the water flow is provided with a first drainage through hole 12 communicating with the first installation g...

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...
