Abstract
The utility model discloses a desilting facility which comprises a flush gallery, a desilting outlet, a gallery deflector hole and a water inlet. The flush gallery is positioned in front of or at the bottom of the water inlet; the desilting outlet is arranged at the tail end of the flush gallery; the gallery deflector hole is formed on the side surface of the side wall of the gallery; and a smooth arc section is adopted at the sharp corner of the gallery deflector hole. The desilting facility can effectively prevent sediment from entering the water inlet, and can ensure the sediment silted up in front of or on the periphery of the gallery can be quickly discharged, and the design of the smooth arc section is adopted at the sharp corner of the gallery deflector hole, therefore, water flow is smooth, the frictional resistance of the water flow is reduced, to be beneficial to the increasing of flow rate of the water flow, simultaneously, the abrasion to concrete by the sediment in the water is reduced, and the service life of the gallery is increased.
Description
Technical field
The utility model relates to the engineering services in a kind of conventional power plant and the hydraulic engineering, especially be suitable for fully-loaded stream, be the shoal materials before eliminating power station, irrigation and the water supply water inlet, reduce the new side formula of diversion tunnel, the interior silting of channel and unit wearing and tearing and arrange husky facility.
Background technology
On fully-loaded stream, the husky problem of the row before power station water inlet or irrigation, the urban water supply mouth always is the problem of a primary study.In the reservoir running, the silt alluvial before the water inlet can be more and more serious, if silt enters diversion tunnel or channel of approach, can be deposited in hole or the canal, influence engineering and use, and then wearing and tearing unit, influence generates electricity.For preventing that silt from entering water inlet, the form of generally taking sand surfing bank, sand trap, bottom hole for sand flushing are set before water inlet is arranged sand.But,, have problems such as sand surfing funnel scope is less, the husky effect of row is undesirable, the husky water requirement of row is bigger owing to be subjected to the restriction that conditions such as flow are quoted in facility, reservoir operation mode and sand surfing.Therefore, need improve arranging husky facility.
Summary of the invention
The utility model aims to provide a kind of husky facility of row that adopts the combination form formation in sunk type lateral intake flush gallery+husky hole of row.
The utility model is a kind of, and to arrange the technical scheme of husky facility as follows:
The husky facility of a kind of row of the utility model comprises flush gallery, arranges husky hole, gallery pod apertures and water inlet, described flush gallery is positioned at the place ahead or the bottom of water inlet, at described flush gallery end the husky hole of row is set, the side of described flush gallery abutment wall has the gallery pod apertures, and slick and sly segmental arc is adopted at the wedge angle position of described gallery pod apertures.
A kind of beneficial effect of arranging husky facility of the utility model is:
1. described gallery is positioned at the place ahead or the bottom of water inlet, and the gallery top is difficult for piling up silt, can prevent effectively that silt from entering water inlet;
2. current strengthen at flush gallery side direction gallery pod apertures place flow velocity, have improved the sediment carrying capacity of current, can make alluvial before gallery and the silt of perimeter zone drain rapidly;
3. the design of slick and sly segmental arc type is adopted at the wedge angle position of gallery pod apertures, makes current smooth-going, has reduced the frictional resistance of current, and is favourable to the increased water flow flow velocity, simultaneously, reduced that silt has improved the application life of gallery to concrete wearing and tearing in the current.
Description of drawings
Fig. 1 is a kind of horizontal profile view of arranging husky facility of the utility model;
Fig. 2 is a kind of longitudinal section view of arranging husky facility of the utility model;
Fig. 3 is a kind of cross sectional view of arranging husky facility water inlet of the utility model;
Wherein, 1, gallery, 2, arrange husky hole, 3, the gallery abutment wall, 4, water inlet, 5, gallery pod apertures.
The specific embodiment
Referring to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the husky facility of a kind of row of the utility model comprises flush gallery 1, row husky hole 2, water inlet 4 and gallery pod apertures 5, described flush gallery 1 is positioned at the place ahead or the bottom of water inlet 4, described flush gallery 1 consequent relief is arranged, the end husky hole 2 of running in, the side of described flush gallery abutment wall 3 has gallery pod apertures 5, and slick and sly segmental arc is adopted at the wedge angle position of described gallery pod apertures 5.
A kind of working method of arranging husky facility of the utility model is: during water inlet 4 water intakings, because the drive of current is deposited on water inlet 4 preceding silts and is brought in the flush gallery 1 of water inlet 4 belows, arrange downstream by the husky hole 2 of the row of flush gallery 1 end.
Claims (1)
1. arrange husky facility for one kind, it is characterized in that: comprise flush gallery, arrange husky hole, gallery pod apertures and water inlet, described flush gallery is positioned at the place ahead or the bottom of water inlet, at described flush gallery end the husky hole of row is set, the side of described flush gallery abutment wall has the gallery pod apertures, and slick and sly segmental arc is adopted at the abutment wall wedge angle position of described gallery pod apertures.
