Down-horizontal-type sluice gate

Abstract

The invention relates to a down-horizontal-type sluice gate comprising a sluice chamber and a sluice gate body and further comprising winches, a roller shaft, rollers, universal wheels, a vertical roller rail groove and a horizontal roller rail groove. A sluice gate face plate is arranged on one side of the downstream the sluice gate body. The sluice gate body is movably fixed in the vertical roller rail groove and the horizontal roller rail groove through the rollers and the universal wheels. The winches are fixed on sluice piers, and steel cables of the winches are connected on the roller shaft at the lower end of the sluice gate body through pulleys. The pulleys are fixed on the sluice piers of the lower portions of steel cable grooves. The winches control the sluice gate body, under the effects of the self-weight of the sluice gate body and upstream water pressure, the upper roller moves toward the downstream direction in the vertical roller rail groove, the lower roller moves horizontally toward the downstream direction in the horizontal roller rail groove to adjust the vertical height difference between the top of the sluice gate body and the upstream water level, the magnitude of the water head above a sluice is guaranteed, and quantitative water taking is completed. When the sluice gate guides water, only the water of the surface layer of a water source is guided. The sediment content is small, the water temperature is high, and the water meets the requirement of the crop growth.

Description

[0001] Technical field: [0002] The invention relates to a descending horizontal gate. Background technique [0003] Generally, the intake sluice is built at the head of the canal. When water is taken directly from the natural river, in order to ensure the introduction of the required flow and minimize the flow of sediment into the canal, sand flushing gates and sand guide sills are usually erected before the intake sluice. The bottom sill of the intake sluice The elevation should be higher than the elevation of the river bottom and the bottom sill of the flushing sluice. Even so, a large amount of sediment is often introduced. Moreover, at present, most of the diversion gates mostly adopt vertical opening and closing gates, resulting in relatively large maneuvering force; when diverting water, the water generally flows downstream from the cross-section between the bottom of the gate and the pier, and the water introduced is the deep part of the water source. The imported wa...

Problems solved by technology

Moreover, at present, most of the diversion sluices mostly adopt vertical opening and closing gates, resulting in relatively large maneuvering force; when water is diverted, the water generally flows downstream from the cross-section between the bottom of the gate and the pier, and the water introduced is the deep part of the water source. The imported water has high sediment content and low water temperature, which is very unsuitable for water diversion in irrigation areas and water diversion requirements of other departments
