Abstract
The present invention provides a kind of anti-tidal bore plane gate, which is integral plane down-the-hole gate of the setting with upstream breastwork before extended-top type arch gate.With solve for there are the power station of larger tidal bore or stormy waves or hydraulic engineering, the prior art is difficult to meet demand, and security risk is larger the problems such as.Belong to hydraulic and hydroelectric engineering technical field.
Description
Technical field
The present invention relates to a kind of anti-tidal bore plane gates, belong to hydraulic and hydroelectric engineering field.
Background technique
For there are the power station of larger tidal bore or stormy waves or hydraulic engineering, because tidal bore water level differ with normal pool level compared with
Greatly, some engineerings are up to 10m or more, if the extended-top types arch gate such as the table hole of water blocking, sluice gate, spillway presses tidal bore
Water level design, then extended-top type arch gate aperture height is too high, some reach 30m or more, causes hydraulic press stroke too long super
Have a technical level, and gate is larger leads to increase that investment is more, and Technical Economy is poor；If being set by normal pool level
Meter can form negative pressure at the gate flap rear portion of gate after then larger tidal bore is gushed out at the top of extended-top type arch gate, generate gas
Capsule impact gate damages, and sometimes results in arc support arm of door unstable failure, causes larger engineering accident, so, the prior art
Or it is incomplete, it needs to be further improved.
Summary of the invention
The present invention provides a kind of anti-tidal bore plane gate, to solve for there are the power station of larger tidal bore or stormy waves or water
The problems such as sharp engineering, the prior art are difficult to meet demand, and security risk is larger.
To solve the above problems, such a anti-tidal bore plane gate of proposed adoption, which worked in extended-top type arc
Integral plane down-the-hole gate with upstream breastwork is set before gate.
In aforementioned anti-tidal bore plane gate, top seal is set, using upstream sealing pattern, plane at the top of plane down-the-hole gate
Inclined-plane water fender is arranged in down-the-hole gate top；
In aforementioned anti-tidal bore plane gate, the import of upstream breastwork is the curved surface steel liner structure higher than flood discharge water surface curve,
Multiple row snorkel is arranged in upstream face, and the exhaust outlet of snorkel is located at the downstream side of upstream breastwork；
In aforementioned anti-tidal bore plane gate, a row of horizontal air inlet pipe, and entrance upstream and downstream is arranged in snorkel from top to bottom
The oblique air inlet pipe in upstream and the oblique air inlet pipe in downstream is arranged in face, and vertical air inlet pipe, the level is vertically arranged in the breastwork of upstream
Air inlet pipe, exhaust outlet, the oblique air inlet pipe of the oblique air inlet pipe in upstream and downstream are connected with vertical air inlet pipe, downstream face it is oblique into
Tracheae is led at the water seal head of top seal；
In aforementioned anti-tidal bore plane gate, horizontal air inlet pipe entrance rounded corner；
Plane down-the-hole gate is usually in water blocking state of closing, and extended-top type arch gate, which is in, closes shape without pressure
Down-the-hole plane gate is first proposed aperture, then sluice by opening extended-top type arch gate when sluicing by state.
Compared with prior art, the present invention is by will be used to overhaul or prevent fault spread before extended-top type arch gate
Extended-top type plane gate transform as setting upstream breastwork plane down-the-hole gate, usually utilize the gate water blocking, arc work
Make gate to be in without pressure closed state, when larger tidal bore or stormy waves occurs, water level will not be gushed out by upstream breastwork, arc work
Make gate is not influenced by tidal bore or stormy waves, and increase investment is less, and the multiple row snorkel of upstream breastwork upstream face setting can incite somebody to action
Tidal bore or the discharge of stormy waves bring gas, effectively prevent the compressed air formed at the top of down-the-hole plane gate to generate gasbag pressure punching
Gate is hit, inclined-plane water fender is arranged in gate top, if gate is when larger tidal bore or stormy waves are impacted, gate deforming tops make to push up water
Envelope occurs being not to damage door body in the case of the jet stream of gap；When sluicing, down-the-hole plane gate is first proposed into aperture, then
It is sluiced by opening arch gate, the import of upstream breastwork is the curved surface steel liner structure higher than flood discharge water surface curve, is being sluiced
When while do not influence discharge and flow-shape, enhance its and keep off the time of tide shock proof performance.
