Description
Technical field
The present invention relates to flood control support field, more particularly to a kind of flood control weir.
Background technology
Dam is just dam for the representative form of water retaining structure.It can be divided into earth dam, gravity dam, CFRD,
Arch dam etc..Dykes and dams are mainly to choke water building in power station.Effect is to raise river level, forms upstream regulation reservoir.Dam
Depend highly on hinge landform, geological conditions, submergence ratio, population migration, the relation of upstream and downstream step power station and dynamic
Energy index etc..By 1989, the height of China's Mainland power station highest dam is 178 meters, in the world highest dam
Highly it is 325 meters (earth and rockfill dams).
But flood occurs when dam is pushed over or needs to remove on dam, because the water-head of upstream and downstream is larger, when
When dam is removed, it is most likely that flood damage can occur, tremendous influence is caused to the physical features in downstream, plant animal, resident etc.,
Accordingly, there exist huge safety factor.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.

Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
Fig. 1 to Fig. 2 shows the structural representation on flood control weir according to the preferred embodiment of the present invention.It is as shown in figure 1, main
Dam 1 is across on river, and the height of key dam 1 is generally 100-170m；Flood control weir includes：Base dam 2, gate 3 and drive device；
Base dam 2 is across the upstream of key dam 1, is specifically preferably placed at the 1-3km of the upstream of key dam 1, and the height on base dam 2 is less than the height of key dam 1
Degree, in order to ensure even in dam dry season, when vacateing the storage capacity phase, the equal depth of water depth that can be passed through of ship, the preferred height on base dam 2
Degree is set to 80-110m, and specifically, key dam 1 is 100m, and base dam 2 is 80m, and 20m height is enough to ensure that ship is opened the navigation or air flight, and base dam 2 is built
Immediately, using bottom current it is basicly stable the characteristics of, clear up river bed silt, drilling edge note base dam bottom reinforcing bar, build up base dam ground,
Simultaneously using the randomness of concrete prefabricated body, be made building block system box board, each precast body have connect with dam body reinforcing bar it is tight pre-
Reinforcing bar processed, box board collectively constitute base dam 2 together with dam body note.
With continued reference to Fig. 1, can be rotatably arranged in the upper end on base dam 2, drive device is connected, is used for gate 3 with gate 3
Drive top rotation of the gate 3 toward Ji Ba or the rotated down toward base dam 2., can be right when gate 3 turns to 2 upper end of base dam
Current further intercept, and prevent the generation of flood, 3 highly preferred 20-40m of gate.
As shown in Fig. 2 show a kind of preferable gate 3 in the embodiment, gate 3 includes positive pricking plate 31 and counter pricking plate
32, drive device is multiple hydraulic cylinders；The positive plate 31 and anti-plate 32 of pricking pricked is that iron pricks plate, and the positive plate 31 and anti-plate 32 of pricking pricked is preferably ladder
Shape, multiple positive lower ends for pricking plate 31 are respectively to be articulated with the side of Ji Ba upper end so that just pricking plate 31 is capable of past base dam 2
Above or below rotate, as can be seen from Figure 2, it is positive prick plate 31 to the upper end on base dam 2 rotate when equivalent to rotating forward；Multiple anti-bundles
The lower end of plate 32 respectively to be articulated with the opposite side of the upper end on base dam 2 so that instead prick plate 32 can be toward above or below base dam 2
Rotate, as can be seen from Figure 2, equivalent to reversion when instead pricking upper end rotation of the plate 32 to base dam 2；It is multiple it is positive prick plates 31 with it is multiple anti-
Prick plate 32 to set in mutually staggered manner respectively, each hydraulic cylinder is used to drive a positive bundle plate 31 or anti-plate 32 of pricking to rotate；
After key dam 1 is removed, just pricking plate 31 and rotated first against current, because multiple positive plates 31 of pricking are smaller with water engaging surface product respectively, because
This, stress is smaller, and positive plate 31 of pricking easily rises, and then instead pricks plate 32 and is risen along current, and stress is smaller, therefore pricks plate 31 using positive
Combined with anti-bundle plate 32 and be easier to control, risen more efficient；Positive prick between plate 31 and anti-bundle plate 32 is provided with mutual card device 4, protects
Card ought just prick plate 31 or anti-plate 32 of pricking turns to the upper end of base dam 2, and the positive plate 31 and anti-plate 32 of pricking pricked can mutually block, more stable.
To sum up, the present invention sets base dam 2 above key dam, and the height on base dam 2 is less than the height of key dam 1, can ensure ship
Navigation only.When key dam 1 is removed, base dam 2 can intercept the water-carrying capacity of a part, avoid generation flood from causing shadow to downstream
Ring；Further, gate 3 is turnable when not in use, to shrink in the side on base dam 2, when flood occurs, Neng Gousheng
Rise and intercept flood, enhance the capacity of preventing floods.
The description of the foregoing specific illustrative embodiment to the present invention is to illustrate and the purpose of illustration.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explain that the certain principles of the present invention and its reality should
With so that those skilled in the art can realize and utilize the present invention a variety of exemplaries and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
