Riverway sluice for hydraulic engineering

Abstract

The invention discloses a riverway sluice for hydraulic engineering, comprising a base arranged in a riverway. The base comprises a bottom plate and a frame-shaped structure defined by two side plates, a gate cavity is formed in the middle of the base, two gate plates overturning towards the outer side face are installed in the gate cavity, two sides of the bottoms of the gate plates are respectively provided with a rotating shaft, the rotating shafts are rotationally installed in rotating shaft holes of the side plates and extend into hollow cavities in the two side plates, the two gate plates are driven by driving assemblies arranged in the hollow cavities to overturn outwards, the bottoms of the two gate plates make contact with the upper end face of the bottom plate in a sealed mode, and the two side faces of the gate plates make contact with the side plates in a sealed mode. The traditional water gate opening mode is changed, the mode that the gate plates are contained at the bottom of the riverway is adopted, the top limiting problem caused by top hoisting is solved, when gate opening and water discharging are conducted, the whole gate does not need to be hoisted, only one gate plate needs to be slightly opened, and more convenience is achieved.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a river sluice for water conservancy engineering. Background technique [0002] Sluices are low-head hydraulic structures built on river courses and channels using gates to control flow and adjust water levels. Closing the gate can block flood, keep tide or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquatic products, environmental protection, industrial and domestic water; opening the gate can vent flood, waterlogging, abandoned water or waste water, or Supply water to downstream channels or channels. In water conservancy projects, sluices are widely used as buildings for retaining, releasing or taking water. [0003] However, at present, many sluices are of the top-lifting type, that is, when opening the sluice, the whole sluice is lifted by using the hoisting steel wire on the top. Because the overall weight of the ...

Problems solved by technology

[0003] However, at present, many sluices are of the top-lifting type, that is, when opening the sluice, the whole sluice is lifted by using the hoisting steel wire on the top. Because the overall weight of the sluice is very large, a large amount of electric energy is consumed to lift the whole sluice, and the lifting The sluice gate has a height limit on the top. At this time, if the top of the transport ship is very high, then when passing through the sluice, its top will touch the lower end of the gate, resulting in the failure of normal passage, and the structure of the top hoisting needs A large number of support frames are added, and the structure is quite complicated. Due to the heavy weight of the sluice gate, each structural part is easy to loosen in the long run, so frequent maintenance is required, otherwise the sluice gate is likely to fall freely after the sluice gate is hoisted. serious safety issue

Moreover, when the sluice is releasing water, as long as all the sluices are lifted, and often the amount of water we need is not large, it is obviously wasteful to lift the entire sluice
