Description
Technical field
The present invention relates to outlet area of ship lock diversing flow system field, more particularly, to a kind of water conservancy diversion isolated niche and its water conservancy diversion side
Formula.
Background technology
Lock approach entrance erea is the throat of ship disengaging approach channel, is the boundary that main stem moves water and approach channel hydrostatic
Region, current shrink or expanded here, and plain bending occurs for hydrostatic interaction in water body and approach channel, current in main stem
Deformation, forms oblique current, influences safety of ship navigation.Therefore, the flow condition for improving lock approach entrance erea has weight
The realistic meaning wanted.Domestic and foreign scholars have studied a variety of Improving Measurements, such as adjustment trraning pole capitiform formula, setting open-cell wall,
Floating embankment and diversion pier etc., different measures are played a part of different to a certain concrete engineering, but have its each
Limitation.In recent years, exposed throughout type isolated niche in bottom is as a kind of new entrance erea diversion structure, during hinge is built at home
Using relatively broad, such as Zhuzhou hinge, Changsha hinge.
But for mountain stream, because hinge upstream and downstream head difference is larger, ship lock lower approach entrance erea hydrodynamic force
Environment is complicated, and entrance erea flow velocity and oblique flow intensity are larger, after current enter entrance erea by isolated niche bottom, easily in entrance erea
The bad fluidised forms such as whirlpool, the water that whirlpools are formed, have a strong impact on that safety of ship is opened the navigation or air flight, current isolated niche is only the form using gear
To prevent oblique current, but fluid is used as, it can bypass cutoff board, form the one stream of water be filled with upwards, and this strand of current exist
Ship running causes the unstable of hull when entering or roll away from lock approach entrance erea, accident easily occurs, so only
Using the form of gear, real needs are insufficient for.
The content of the invention
It is an object of the invention to provide a kind of isolated niche simple in construction, simple to operate, production efficiency is high, it is especially suitable for changing
The flow condition of charitable family mouth region.
The technical scheme is that：
A kind of water conservancy diversion isolated niche and its diversion mode, including several support groups, between the adjacent support group of any two
Plate is connected with, the support group links pier and second including first and links pier, set between the adjacent support group of each two
Be equipped with a plate, the support group in one end left side adjacent thereto of the plate is connected, the plate it is another
The support group on right side adjacent thereto is held to be connected, and described first in each support group is linked on pier only with one
The individual plate is connected, and described second in each support group links only to be connected on pier with a plate.
Further, each support group bottom is provided with cushion cap, described first in same support group link pier and
Described second, which links pier, is fixedly installed on the cushion cap, and described first in same support group links pier and described second and connected
It is that both piers are parallel to each other.
Further, the plate is linear panel.
Further, the plate is curve-shaped panel.
Further, the plate is bottom honeycomb duct to gap, this gap is left between the cushion cap.
Further, described first in same group of support group links pier and described second and links and leave gap between pier, this
Gap is vertical honeycomb duct.
A kind of diversion mode realized using above-mentioned water conservancy diversion isolated niche：
The device is mainly used in mitigating impact of the oblique current to ship：
The first diversion mode is：Oblique current are stopped by plate, mitigate the impact to ship,
Second of diversion mode be：The oblique current that script is concentrated are disperseed, weakened by bottom honeycomb duct by oblique current
Oblique flow dynamic intensity, while reduce vertical honeycomb duct inflow-rate of water turbine,
The third diversion mode is：Oblique current pass through vertical honeycomb duct, while rely on plate, and oblique current are changed into edge
The oblique current in plate direction, while offset the ascending current for entering entrance erea by bottom honeycomb duct.
Such a water conservancy diversion form is excellent only to be stopped oblique current in existing isolated niche, existing isolated niche,
The bad fluidised forms such as whirlpool, the water that whirlpools are also easy to produce in the case that hydrodynamic intensity is larger in entrance erea, jeopardize ship's navigation, in addition,
Such a mode greatly, it is necessary to often safeguarded to equipment, causes maintenance cost high, but use in the application equipment damage
Scheme baffle is combined with water conservancy diversion, both reduced transverse flow speed in entrance erea, suppressed whirlpool again, the bad fluidised form such as the water that whirlpools
Formation, while reduce impact of the current to equipment, increase service life.
The present invention has the advantages and positive effects of：Due to being had the following advantages that using above-mentioned technical proposal, the present apparatus：
1st, it is effectively improved lock approach navigation through the gap flow condition.
1st, using more convenient, there is simple in construction, easy to maintenance, the advantages that processing cost is low, production efficiency is high.
2nd, plate is divided into two kinds of linear and shaped form, can so be constructed according to different actual conditions.
3rd, the present apparatus stops that the oblique current in sluice gate area ensure safety of ship using stopping and dredging by the way of current.
4th, plate is plugged on to link and is convenient for changing on pier.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of the present invention.
In figure：
1st, cushion cap 2, first link pier 3, second link pier
4th, plate 5, vertical honeycomb duct 6, bottom honeycomb duct
Embodiment
As shown in figure 1, a kind of water conservancy diversion isolated niche of the present invention and its diversion mode, including several support groups, any two
