Abstract
The invention relates to the technical field of water conservancy and hydropower, in particular to a flip bucket. The flip bucket comprises a side wall and a bottom plate. The side wall is a circular arc camber side wall with an upright single side. The beneficial effects that the upright circular arc camber side wall of the flip bucket is good in diffusion ability and water flow guide performance are utilized, the water flow regression condition is improved; especially for the condition that the center line of a discharge chute and a downstream river channel obliquely cross by a large angle, the water flow state is smooth and stable, a water tongue is longitudinally stretched to the largest extent, and washing to a bank slope and a slope toe is reduced to the largest extent; and meanwhile the flip bucket has the advantages that the structure is simple, construction is easy, and cost is low.
Description
Technical field
The present invention relates to water conservancy and hydropower technical field, specifically, relate to a kind of one-sided circular arc abutment wall flip bucket uprightly.
Background technology
The key of flip trajectory bucket is that the build of flip bucket is selected, the basic principle selected is the changeability of the property led and the active cross-section shape utilizing high-velocity flow to flow to, by directed for high-velocity flow to downstream impelling, and can according to landform geologic condition need make the impelling of water stock to predetermined place.Because overflow eliminates portion of energy along dam facing and diffusion aloft, washing away underwater bed can be greatly reduced.Flip bucket structure is simple, easy construction, saving engineering quantity, therefore the outlet structure escape works outlet of the overwhelming majority adopts flip bucket.
The most frequently used and effective flip bucket pattern comprises at present: continuously bank, slotted flip bucket, flip bucket, tiltedly choose bank, skew bucket, height bank (or claim differential greatly choose formula), slit, baffle pier choose bank, above flip bucket is in the face of the orographic condition in narrow dark type river valley, particularly let out groove center line becomes wide-angle oblique situation with downstream river course, under let out flow-shape instability, comparatively large to washing away of bank slope and toe, be further improved.
Summary of the invention
The object of the present invention is to provide a kind of flip bucket, to solve the problem.
The embodiment provides a kind of flip bucket, comprising: abutment wall and base plate, this abutment wall is upright one-sided circular arc camber abutment wall.
Further, this base plate is linear pattern base plate or with the circular arc type base plate choosing angle.
Further, the height of this upright one-sided circular arc camber abutment wall increases gradually along downstream direction.
Compared with prior art the invention has the beneficial effects as follows: the feature that one-sided circular arc abutment wall diffusion is good and current deflecting is good utilizing flip bucket upright, what improve current returns groove condition, particularly for the situation of letting out groove center line and to become with downstream river course wide-angle oblique, flow-shape is smooth-going stable, overflow is longitudinal stretching as much as possible, reduce washing away bank slope and toe to greatest extent, have simultaneously structure simple, be easy to construction, low cost and other advantages.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of flip bucket of the present invention;
Fig. 2 is the top view of a kind of flip bucket of the present invention.
Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, the present invention is described in detail; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection scope of the present invention.
Shown in ginseng Fig. 1 and Fig. 2, Fig. 1 is the front view of a kind of flip bucket of the present invention, and Fig. 2 is the top view of a kind of flip bucket of the present invention.
Present embodiments provide and The embodiment provides a kind of flip bucket, comprising: base plate 1 and abutment wall 2, this base plate 1 is linear pattern base plate, and this abutment wall 2 is upright one-sided circular arc camber abutment wall.Upright one-sided circular arc camber abutment wall with let out the one-sided abutment wall end of groove and be smoothly connected.
The flip bucket that the present embodiment provides is under the orographic condition in narrow dark type river valley, particularly for the situation of letting out groove center line and to become with downstream river course wide-angle oblique, current are smooth-going stable, less washing away bank slope and toe, have simultaneously structure simple, be easy to construction, low cost and other advantages.
In the present embodiment, the efficiency of flip bucket is mainly relevant with the height of upright one-sided circular arc type abutment wall and arc radius and angle, the determination of these forms, main or dependence hydraulic model test at present, according to flow condition and the topographic and geologic condition of flood releasing structure outlet, from overflow spreading morphology, enter water level and put, the top of bank slope rushed to the aspects such as situation by test and abutment wall geomery is determined in calculating, fall into the set goal position to make flip shot current.
In the present embodiment, this abutment wall is the height of upright left circles arc surface abutment wall, and the height of abutment wall increases gradually along downstream direction.
In the present embodiment, this base plate 1 can adopt linear pattern base plate.
Shown in ginseng Fig. 1,2, in this example, L1 is the transition section length that linear pattern base plate is connected with chute bottom slab, and L2 is the length of linear pattern base plate, and L3 is the height of upright left circles arc-shaped curved surface abutment wall, L4 and L5 is respectively the length of linear pattern base plate; R1 is the radius of the changeover portion that linear pattern base plate is connected with chute bottom slab, and R2 is the radius of upright left circles arc-shaped curved surface abutment wall.L1＝2.96m，L2＝21.34m，L3＝18.89m，L4＝11.4m，L5＝13.97m，R1＝30m，R2＝35m。
This example lets out groove outlet flip bucket build according to incoming flow feature and downstream river course topographic features, adopt upright one-sided circular arc type abutment wall flip bucket, the feature that diffusion is good and current deflecting is good of the one-sided circular arc type abutment wall utilizing flip bucket upright, that improves current returns groove condition, overflow longitudinal stretching as much as possible simultaneously, reduce washing away left bank bank slope and toe to greatest extent, this flip bucket structure is simple, be easy to construction, flow-shape is smooth-going stable, is specially adapted to let out groove center line becomes wide-angle oblique situation with downstream river course.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.
