Abstract
The present invention provides a kind of anti-tidal bore extended-top type plane gate, which is to add the tidal gate of a folded gear normal pool level to water body between tidal bore water level on the extended-top type plane gate top 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 extended-top type 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, reaches 30m or more, causes hydraulic press stroke too long beyond existing
Have a technical level, and gate it is larger cause to increase investment it is more；If designing by normal pool level, larger tidal bore is pushed up from dew
Negative pressure can be formed at the gate flap rear portion of gate after gushing out at the top of formula arch gate, generate air bag impact gate and damage,
Arc support arm of door unstable failure is sometimes resulted in, larger engineering accident is caused, so, the prior art or incomplete, up for
It further increases.
Summary of the invention
The present invention provides a kind of anti-tidal bore extended-top type plane gate, to solve for there are the water power of larger tidal bore or stormy waves
It stands or hydraulic engineering, the prior art is difficult to meet demand, and the problems such as security risk is larger.
To solve the above problems, such a anti-tidal bore extended-top type plane gate of proposed adoption, which is in extended-top type arc
The gear tide of a folded gear normal pool level to water body between tidal bore water level is added on extended-top type plane gate top before shape main gate
Gate.
In aforementioned anti-tidal bore tidal gate, tidal gate bottom seal fulcrum bearing is arranged in extended-top type plane gate top；
Extended-top type plane gate and tidal gate, which are usually in, closes water blocking state, and extended-top type arch gate is in
Without pressure closed state, when sluicing, tidal gate and extended-top type plane gate are successively proposed, be then turned on extended-top type arc work lock
Door.
Compared with prior art, the present invention passes through in traditional folded normal water storage of gear of extended-top type plane gate top setting one
Position usually utilizes the gate water blocking, arch gate is in closes without pressure to the tidal gate of water body between tidal bore water level
State, when larger tidal bore or stormy waves occurs, water level will not be gushed out by the tidal gate on top, and arch gate is not gushed
It is less to increase investment for the influence of tide or stormy waves, and the panel of extended-top type plane gate and tidal gate exists substantially in same plane
The junction of two gates will not generate compressed air, and tidal gate top is higher than tidal bore or stormy waves is extended-top type, and ventilation is abundant,
It basically will not produce compressed air, therefore impacts gate without gasbag pressure substantially, the safety of gate structure has been effectively ensured；Extended-top type
Tidal gate bottom seal fulcrum bearing is arranged in plane gate top, and tidal gate bottom seal and extended-top type plane gate has been effectively ensured
Contact it is close, enhance water-stagnating effect；When sluicing, successively proposes tidal gate and extended-top type plane gate, be then turned on arc
Main gate does not influence discharge and flow-shape.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
The detailed description of step, it should be understood that described herein specific examples are only used to explain the present invention, is not used to limit this hair
It is bright.
Embodiment
Referring to Fig.1, the present embodiment provides a kind of anti-tidal bore extended-top type plane gate, which worked in extended-top type arc
The tidal gate of a folded gear normal pool level to water body between tidal bore water level is added on 2 top of extended-top type plane gate before gate 1
3, tidal gate bottom seal fulcrum bearing 4 is arranged in 2 top of extended-top type plane gate.
In closing water blocking state, extended-top type arch gate 1 when extended-top type plane gate 2 and flat tidal gate 3
In without pressure closed state, when sluicing, successively proposes tidal gate 3 and extended-top type plane gate 2, be then turned on extended-top type arc
Main gate 1.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
