Existing large hydropower station irrigating gate design is as shown in figure 1, in large-scale power station generating irrigating gate opening position, reservoir river
When bed line is higher, in the case that reservoir depth is relatively shallower, Sediment Siltation is easily produced before generating irrigating gate, so causes to generate electricity
Underfed, and wear-out failure of the silt to generating set are quoted, generating diversion quality is reduced and threatens the safety fortune of factory building
OK, potential safety hazard is brought to engineering.
Utility model content
The utility model provides a kind of large hydropower station water inlet scour gallery, and mud is easily produced before solving generating irrigating gate
Sand alluvial, cause to generate electricity and quote underfed, wear-out failure of the silt to generating set, asking for potential safety hazard is brought to engineering
Topic.
Technical scheme is used by the utility model solves its technical problem：Large hydropower station water inlet scour gallery,
Including multiple generating irrigating gates, generating irrigating gate forms fabricated structure, and the bottom of each generating irrigating gate sets sand surfing respectively
Gallery, each bar scour gallery are respectively connecting to sand surfing Main Corridor road, and the water inlet of each bar scour gallery sets scour gallery respectively
Gate, the downstream of scour gallery gate set passage, and scour gallery and sand surfing Main Corridor road are arranged in generating irrigating gate
In underplate concrete.
It is further：Main Corridor road gate is set on the sand surfing Main Corridor road, and Main Corridor road gate is located at any sand surfing corridor
The downstream in road.
It is further：The cross section of scour gallery at the scour gallery gate is rectangular；Main Corridor road gate
The cross section in the sand surfing Main Corridor road at place is rectangular.
It is further：The sand surfing Main Corridor road incrementally increases in connection scour gallery part along the diameter of water (flow) direction.
It is further：Linkage section between the scour gallery and sand surfing Main Corridor road is curved.
It is further：Copper sheet sealing and rubber water-proof are respectively provided with the inside of the scour gallery, sand surfing Main Corridor road.
The beneficial effects of the utility model are：The generating irrigating gate bottom of large hydropower station sets scour gallery, when there is mud
Lift scour gallery gate sand surfing during sand alluvial, efficiently solve Sediment Siltation problem before generating irrigating gate, ensure that generating is drawn
The safe operation of water quality and factory building.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figs. 2 to 4, the utility model large hydropower station water inlet scour gallery, including multiple generating irrigating gates 1,
Generating irrigating gate 1 forms fabricated structure, and the bottom of each generating irrigating gate 1 sets scour gallery 2, each bar scour gallery respectively
2 are respectively connecting to sand surfing Main Corridor road 3.Scour gallery 2 and sand surfing Main Corridor road 3 are arranged in the underplate concrete 6 of generating irrigating gate 1
In.
Such as Fig. 2, scour gallery 2 is four, and four scour gallerys 2 are parallel to each other, and with the axis direction of sand surfing Main Corridor road 3
Angle be 92 °.The water inlet of each bar scour gallery 2 sets scour gallery gate 4, the downstream of scour gallery gate 4 respectively
Side sets passage 5.Such as Fig. 3, passage 5 is arranged at the upstream side of the trash rack 10 of generating irrigating gate 1, the diameter of passage 5
For 50mm, scour gallery gate 4 is arranged at the upstream side of passage 5.The cross section of scour gallery 2 at scour gallery gate 4
Rectangular, this section of scour gallery 2 is gate bay.Gate bay upstream side is the water inlet of scour gallery 2, and water inlet is in open-like shape,
Such as Fig. 2；The downstream of gate bay is the changeover portion that square tube becomes pipe.Linkage section between scour gallery 2 and sand surfing Main Corridor road 3 is in
Arc.
Main Corridor road gate 7 is set on sand surfing Main Corridor road 3, and Main Corridor road gate 7 is located at the downstream of any scour gallery 2.
The cross section in the sand surfing Main Corridor road 3 at Main Corridor road gate 7 is rectangular.So the sand surfing Main Corridor road 3 at Main Corridor road gate 7 is lock
Gate segment, the upstream side of the gate bay set the changeover portion of pipe change square tube.
Due to the changes in flow rate in sand surfing Main Corridor road 3, sand surfing Main Corridor road 3 is connecting the part of scour gallery 2 along water (flow) direction
Diameter incrementally increases.Such as Fig. 2, sand surfing Main Corridor road 3 is 330mm in one section of maximum gauge of first scour gallery 2 of connection, even
One section of maximum gauge for connecing second scour gallery 2 is 360mm, connects one section of maximum gauge of the 3rd scour gallery 2
For 400mm.Scour gallery 2, the inner side of sand surfing Main Corridor road 3 are respectively provided with copper sheet sealing 8 and rubber water-proof 9.Such as Fig. 4, sand surfing Main Corridor road 3
Inner side sets copper sheet sealing 8 and rubber water-proof 9.
Scour gallery 2 efficiently solves Sediment Siltation problem before generating irrigating gate 1, it is ensured that generating diversion quality and factory
The safe operation in room.
