Description
Technical field
This utility model belongs to hydraulic engineering technical field, the multi-functional overfall dam in more particularly to a kind of small-sized river course.
Background technology
Overfall dam, dam crest can flood discharge dam, also known as overflow dam.Overfall dam is typically built up by concrete or stone masonry.By dam
Type has overflow gravity dam, overflow arch dam, overflow buttress dam and overflow earth and rockfill dam.The latter is only limitted to spillwag chute and base of dam reliable anti-
The smaller weir of shield facility, discharge per unit width.It is combined together with Factory Building, as the power-house within the dam overflow of flood releasing structure
Dam, overflow type and factory's dam joint flood discharge mode of more Factory Building top earial drainage is chosen, can be used on high mountain glen area, be to lead big stream off
During amount, the not enough a kind of approach of spillway and Power Plant position, and the new model grown up from overfall dam is solved.
Through retrieval, Authorization Notice No. includes and blocks for a kind of overfall dam for being provided with waterwall of 202298574 U of CN
Sill may, overfall dam, sluice, it is characterised in that：Column is interval with overflow dam body center upper portion along overfall dam length direction,
Column both sides are provided with slot, are provided with soft quality partition pad in slot, are plugged with water fender in the slot of two columns, plate body top with let out
Hong Zha tops are equal, power station flat, dry season using this utility model can a larger increase power station conservation storage, improve head
Highly increase generating efficiency and economic benefit, while the pondage and time when can increase power station electricity consumption peak valley, electricity consumption is low
Develop motor during paddy less, increase water-retention, improve head height, and group of motors can be developed during peak of power consumption more, use can be extended again
Electric rush hour, peak interval of time electricity price difference are very big, and economic benefits of power generating increases many.When annual flat, dry season typically constitutes from whole year
Between more than 2/3, the utility model is only suitable in large-scale waters construction, for compared with river channel and not applying to, and compared with river channel
Electric station is built unlikely.
The content of the invention
The purpose of this utility model is to overcome deficiency in prior art, there is provided a kind of convenient small-sized river of flow cavitation result
The multi-functional overfall dam in road.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of multi-functional overfall dam in small-sized river course, including dam body, bridge floor, discharge opening, rotating shaft, curved baffle, hydraulic stem, lets out
