Abstract
The utility model discloses a power station hub downstream water supply structure, relates to the field of water conservancy projects, and provides a power station hub downstream water supply structure which allows high-stroke power station hubs without permanent water release channels and low-stroke power station hubs without permanent water release channels to supply water to the downstream position during the period when diversion release structures are braked and blocked. The power station hub downstream water supply structure comprises a reservoir, a diversion hole and a diversion hole brake system. The diversion hole brake system controls opening and closing of the diversion hole. The portions, on the two sides of the diversion hole brake system, of the diversion hole are a diversion hole upstream section and a diversion hole downstream section respectively. The diversion hole upstream section is communicated with the reservoir. The power station hub downstream water supply structure further comprises a bypass hole and a bypass hole brake system. The two ends of the bypass hole are communicated with the reservoir and the diversion hole downstream section respectively. The bypass hole brake system controls opening and closing of the bypass hole. During the period when the diversion hole is closed through the diversion hole brake system, the bypass hole releases ecological flow which meets the requirement to a downstream channel. River water enters the diversion hole through the bypass hole, and then enters the downstream channel through the diversion hole.
Description
Technical field
The utility model relates to hydraulic engineering field, especially designs a kind of hub station downstream water supply structure.
Background technology
Low elevation during the shutoff of water conservancy diversion outlet structure escape works, tends to cause river course cutout without the hub station of permanent drainage gallery.For meeting downstream industry, agricultural production and the people's living water use needs, often adopt pumping for water pump, syphon to supply water, establish interim bypass pipe and valve supplies water, the water intaking of tributary, downstream, downstream river course are established the measures such as interim barrage retaining and supplied water.Along with Chinese society economic development; the consciousness of preserving the ecological environment and requirement are more and more higher; newly-built Hydraulic and Hydro-Power Engineering requires river course to continue to flow during lock shutoff under water conservancy diversion outlet structure escape works in recent years, and requires to let out river channel ecology flow by 10% time of dam site section average annual flow.Aforementioned pumping for water pump, syphon supply water, establish interim bypass pipe and valve supplies water, fetch water in tributary, downstream, downstream river course is established the measures such as interim barrage retaining and generally can only be met low discharge water needs, is difficult to meet larger downstream river course ecological flow requirement.For this reason, need to study that a kind of technology is reliable, the novel building structure scheme of economical rationality, to meet the downstream river course ecological flow requirement of releasing.
Utility model content
The technical problems to be solved in the utility model is: the hub station downstream water supply structure that provides a kind of low elevation to supply water downstream during lock shutoff under water conservancy diversion outlet structure escape works without the hub station of permanent drainage gallery.
For the technical scheme that addresses the above problem employing is: hub station downstream water supply structure comprises reservoir, Diversion Tunnel and Diversion Tunnel gate system, Diversion Tunnel gate system control Diversion Tunnel break-make, the part that Diversion Tunnel is positioned at Diversion Tunnel gate system both sides is respectively Diversion Tunnel Upstream section and Diversion Tunnel tract, Diversion Tunnel Upstream section is communicated with reservoir, hub station downstream water supply structure also comprises bypass hole and bypass hole gate system, two ends, bypass hole are communicated with reservoir and Diversion Tunnel tract respectively, gate system control bypass hole, bypass hole break-make.
Further: bypass hole and reservoir link position are higher than Diversion Tunnel Upstream section and reservoir link position.
The beneficial effects of the utility model are: during Diversion Tunnel gate system closed stream lending hole, bypass hole is the river course ecological flow meeting the demands of releasing downstream.River enters Diversion Tunnel by bypass hole, then enters downstream river course by Diversion Tunnel.
Accompanying drawing explanation
Fig. 1 is hub station downstream water supply structural representation;
Fig. 2 is hub station downstream water supply structure cross-sectional view;
In figure, be labeled as: Diversion Tunnel 1, Diversion Tunnel gate system 2, Diversion Tunnel gate 3, Diversion Tunnel lock chamber 4, bypass hole gate system 5, bypass hole gate 6, bypass hole lock chamber 7, bypass hole 8, Diversion Tunnel tract 9.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Hub station downstream water supply structure comprises reservoir, Diversion Tunnel 1 and Diversion Tunnel gate system 2, Diversion Tunnel gate system 2 is controlled Diversion Tunnel 1 break-make, the part that Diversion Tunnel 1 is positioned at Diversion Tunnel gate system 2 both sides is respectively Diversion Tunnel Upstream section and Diversion Tunnel tract 9, Diversion Tunnel Upstream section is communicated with reservoir, hub station downstream water supply structure also comprises bypass hole 8 and bypass hole gate system 5,8 two ends, bypass hole are communicated with reservoir and Diversion Tunnel tract 9 respectively, and bypass hole gate system 5 is controlled bypass hole 8 break-makes.During Diversion Tunnel gate system 2 closed stream lending holes 1, bypass hole 8 is the river course ecological flow meeting the demands of releasing downstream.River enters Diversion Tunnel 1 by bypass hole 8, then enters downstream river course by Diversion Tunnel 1.
The same with common gate system, Diversion Tunnel gate system 2 comprises Diversion Tunnel gate 3 and Diversion Tunnel lock chamber 4, bypass hole gate system 5 comprises bypass hole gate 6 and bypass hole lock chamber 7, gate directly blocks current, prevent that current from flowing through cavern, lock chamber regulating gate moves and provides mobile space for gate.The cross sectional area in bypass hole 8 is answered accurate Calculation, makes it can meet the lower requirement of letting out at present ecological flow of water level after 1 time lock of Diversion Tunnel, can meet again the requirement of water level reservoir filling when higher.
Further, bypass hole 8 and reservoir link position are higher than Diversion Tunnel Upstream section and reservoir link position.Can meet so the lower requirement of letting out at present ecological flow of water level after 1 time lock of Diversion Tunnel, can avoid again riverbed bed load sediment to enter bypass hole 8, and then wear-out failure bypass hole structure.
