Description
Technical field
The utility model relates to hydraulic structure, is specifically related to a kind of pumped storage power plant vertical shaft type inlet/outlet mouth structure.
Background technology
Inlet/outlet is hydraulic structure important in pumped storage power plant, has the feature of bimodal current, in the time that current pass in and out, will have enough conveyance capacities, and requires head loss little, and current are even, without being harmful to air-breathing whirlpool etc.
Vertical shaft type inlet/outlet is one of main water inlet pattern of pumped storage power plant, is generally arranged in reservoir bottom, and position is comparatively flexible, stronger to the compliance of landform geological conditions, but flow condition is comparatively complicated, and structure design difficulty is larger.Therefore, selecting good build and structural system is the key of vertical shaft type inlet/outlet design.
In prior art, the gate pier build of vertical shaft type inlet/outlet is different, and conventional is the rectangular structure of edge chamfering.Generally there is following defect in the different gate pier of build: (1) head loss is larger, and (2) fluidised form is bad, and current disorder is prone to whirlpool and crossing current.
Utility model content
For above-mentioned technical problem, the utility model aims to provide a kind of pumped storage power plant vertical shaft type inlet/outlet mouth structure, to adapt to the feature of pumped storage power plant bimodal current, has better flow condition and structure stress condition.
The technical scheme that the utility model is dealt with problems is: a kind of pumped storage power plant vertical shaft type inlet/outlet mouth structure, the base of reserved runner in the middle of comprising, on base, be the radial gate pier that is provided with column structure, in the gate slot of gate pier, be provided with gate, gate pier is provided with the cover plate of bottom centre with fiaring cone, this gate pier is column structure, the cross section of described cylinder is fan-shaped, comprise the protruding A circular arc to upstream face, and at back side and protruding in contrary B circular arc with A circular arc, the arc length of described A circular arc is greater than the arc length of B circular arc, the dual-side of the fan shaped cross section of described cylinder adopts the straight line narrowing gradually respectively A circular arc to be connected with B circular arc.
As the further improvement of technique scheme, described cover plate is provided with and the integrated semiclosed cylinder of cover plate, and this cylinder and cover plate have common central axis, and the outer wall of described cylinder is near gate but and leave gap between gate.
In technique scheme, the layout quantity of described gate pier determines according to the scale of concrete engineering application, and for making current even, described gate pier is preferably and is uniformly distributed at inlet/outlet place.
The beneficial effects of the utility model are:
1. be fan-shaped column structure gate pier owing to having adopted cross section, afterbody narrows, and planar diffusion angle (being angle of throat when generating operation mode) angle when pumping operation mode between two adjacent gate piers reduces, thereby make current have the transition of gradual change, current are smooth-going, and head loss reduces, and fluidised form improves.
2. the cylinder arranging on cover plate has improved the supporting condition of cover plate periphery, makes coverplate stress more reasonable, plays breastwork effect in the time of closing gate simultaneously, is conducive to form gate top water column.

Fig. 1 is the longitudinal plan of the utility model vertical shaft type inlet/outlet mouth structure.
Fig. 2 is the top view of the utility model vertical shaft type inlet/outlet mouth structure.
Fig. 3 is the utility model gate pier build and arranges top view.
In figure, 1-gate pier, 2-gate slot, 3-A circular arc, 4-B circular arc, 5-base, 6-cover plate, 7-cylinder, 8-gate.
Detailed description of the invention
As shown in Figures 1 to 3, a kind of pumped storage power plant vertical shaft type inlet/outlet mouth structure, the base 5 of reserved runner in the middle of comprising, on base 5, be radial 8 gate piers 1 that are laid with column structure, in the gate slot 2 of gate pier 1, be provided with gate 8, gate pier 1 is provided with the cover plate 6 of bottom centre with fiaring cone, this gate pier 1 is column structure, the cross section of described cylinder is fan-shaped, comprise the protruding A circular arc 3 to upstream face, and at back side and protruding in contrary B circular arc 4 with A circular arc 3, the arc length of described A circular arc 3 is greater than the arc length of B circular arc 4, the dual-side of the fan shaped cross section of described cylinder adopts the straight line narrowing gradually respectively A circular arc 3 to be connected with B circular arc 4.
Described cover plate 6 is provided with and the integrated semiclosed cylinder 7 of cover plate, and this cylinder 7 has common central axis with cover plate 6, and the outer wall of described cylinder 7 is near gate 8 but and leave gap between gate.
When construction, first build base 5 according to lower to upper order, then build the gate pier 1 of cover plate below 6, build again afterwards cover plate 6 and cylinder 7.
Claims (2)
1. a pumped storage power plant vertical shaft type inlet/outlet mouth structure, the base of reserved runner in the middle of comprising, on base, be the radial gate pier that is provided with column structure, in the gate slot of gate pier, be provided with gate, gate pier is provided with the cover plate of bottom centre with fiaring cone, it is characterized in that: this gate pier is column structure, the cross section of described cylinder is fan-shaped, comprise the protruding A circular arc to upstream face, and at back side and protruding in contrary B circular arc with A circular arc, the arc length of described A circular arc is greater than the arc length of B circular arc, the dual-side of the fan shaped cross section of described cylinder adopts the straight line narrowing gradually respectively A circular arc to be connected with B circular arc.
