Abstract
The utility model provides a can control the bank is chosen to multistage formula of cutting sth. Askew of main overflow placement, including bottom plate and side wall, the side wall is provided with twice, and the twice side wall sets up the both ends at the bottom plate respectively, export that bottom plate and side wall formed is the formula of cutting sth. Askew, uses the outlet structure escape works axis as the reference promptly, and the length that lies in bottom plate and the side wall of outlet structure escape works axis one side is greater than the length of opposite side bottom plate and side wall, the bottom plate edge that is located the exit comprises two sections line segments at least. Owing to adopted to constitute the bottom plate edge including curved multistage line, just so can utilize the jet impulse principle, to control the exit position through optimizing, choose angle size, anti - arc radius and outlet edge circle profile, the overflow region of entrying is adjusted to the flexibility.
Description
Technical field
The utility model is related to a kind of flip trajectory bucket structure being applied to the outlet of high-velocity flow outlet structure escape works.
Background technology
According to conditions such as engineering geology, landform, the hydrology, high-velocity flow outlet structure escape works jet bucket Dam Configuration Design not only will
Using stream of carrying water and smoothly returning groove, and dispersion of flow degree of growing will be increased as far as possible, with the skyborne blending of increased water flow, disorderly
Dynamic, friction energy dissipation and reduce the flow that overflow enters in water unit area and to reduce current energy is washed away to downstream river course
Power.
It is single straight line that traditional inclined cutout chooses bank outlet sideline, and application is relatively wide, and outlet trajectory nappe has certain horizontal stroke
To with longitudinal diffusion degree.But for the engineering that downstream river course is narrow, its overflow drop point suffers from limiting, and needs to outlet sideline
Inclined cutout for single straight line is chosen bank and is improved, and makes overflow neither wash away opposite bank, also not this bank of scour, and overflow can be made fully vertical
To stretching, and main overflow drop point can be controlled.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of energy to control the multistage inclined cutout of main overflow drop point to choose
Bank.
The utility model solves the multistage inclined cutout that its technical problem adopted and chooses bank, and including base plate and side wall, side wall sets
It is equipped with twice, twice side wall is separately positioned on the two ends of base plate；The outlet of base plate and side wall formation is inclined cutout, is built with sluicing
Building thing axis is reference, and the base plate positioned at outlet structure escape works axis side and the length of side wall are more than opposite side base plate and side wall
Length；Bottom edge positioned at exit is at least made up of two sections of line segments.
It is further to include horizontal line, oblique line or curve positioned at the composition of the bottom edge in exit.
It is further that described base plate is iso-curvature curved surface or warp surface.
It is further that the width in exit for the described base plate is not less than the width at other positions.
It is further that described side wall is linear or shaped form.
The beneficial effects of the utility model are：Multi-section-line due to employing including curve constitutes bottom edge, thus
Jet impulse principle can be utilized, by optimizing left and right exit position, choosing angle size, anti-arc radius and outlet border profile, spirit
Adjustment overflow of living enters aqua region.The feature of bank, the orographic condition of flood discharge hole outlet and flow condition are chosen according to inclined cutout, to choosing stream
Bucket lip using serious mistake away from, choose greatly angular difference, fold-line-shaped exports the abnormal shape of leading edge and cuts sth. askew and choose bank pattern, increase as far as possible and choose to go out about bank
Before and after mouthful, mistake flows shooting angle difference away from choosing, and makes the lower stream that sluices along river course longitudinal extension；Export fold-line-shaped by adjusting base plate
Location and shape, well control main overflow drop point, to adapt to the outlet structure escape works that downstream river course is narrow, outlet arrangement is limited
Exit condition.
Brief description
Fig. 1 is plan of the present utility model；
Fig. 2 is side view of the present utility model；
In figure parts, position and numbering：Side wall 1, base plate 2, bottom edge 3, outlet structure escape works axis 4.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes base plate 2 and side wall 1, side wall 1 is provided with twice, and twice side wall 1 sets respectively
Put the two ends in base plate 2；It is characterized in that：The outlet of base plate 2 and side wall 1 formation is inclined cutout, that is, with outlet structure escape works axis 4
It is reference, the base plate 2 positioned at outlet structure escape works axis side and the length of side wall 1 are more than the length of opposite side base plate 2 and side wall 1
Degree, makes the bottom edge 3 positioned between both walls 1 termination be at least made up of two sections of line segments, or horizontal line or oblique line or curve sets
Meter.The outlet of base plate 2 and side wall 1 formation is positive inclined cutout or reverse inclined cutout.The benefit of this structure is exactly, bottom edge
3 can form different outlet sidelines by the combination of horizontal line or oblique line and curve, thus effectively controlling main overflow to fall
Point, under different engineerings, the particularly narrow engineering of downstream river course has good adaptability, so that overflow is neither washed away right
Bank, also not this bank of scour, the abundant longitudinal stretching of overflow can be made, and main overflow drop point can be controlled.
Specifically, as shown in figure 1, from the beginning of the shorter side of base plate 2, the bottom edge 3 positioned at exit is followed successively by water
Horizontal line, oblique line or curve.This polymorphic type line segment can form different bottom edge 3 shapes, thus adapting to different situations.
Base plate 2 may be configured as various shapes, is specifically as follows iso-curvature curved surface or warp surface.Base plate 2 can for wide or
Not wide, for example the width in exit for the base plate 2 is more than the width at other positions.Equally, described side wall 1 can also be straight line
Shape or shaped form.
The utility model utilizes current jet impulse principle, and current of growing project from base plate outlet edge 3, by adjusting side
Wall 1 exit position, choose angle size, anti-arc radius and outlet border profile, to defrlector bucket using serious mistake away from, choose greatly angular difference, many
The abnormal shape that section fold-line-shaped exports leading edge is cut sth. askew and is chosen bank pattern, increase as far as possible choose before and after outlet about bank wrong away from choose outflow firing angle
Degree difference, makes the lower stream that sluices along river course longitudinal extension；According to the dependency relation choosing angle and sater professionals, adjust base plate outlet broken line
The location and shape of shape, thus overflow is adjusted flexibly enter aqua region, and well control main overflow drop point, narrow to adapt to downstream river course
The outlet structure escape works exit condition narrow, outlet arrangement is limited.
