Description
Technical field
The utility model relates to a kind of high narrow big aperture inlet gate drainage arrangements, belong to hydraulic and hydroelectric engineering metal structure
Technical field.
Background technique
For water inlet stop gate or axis stream unit water inlet emergency gate（Hereinafter referred to as inlet gate）, generally use
One machine arrangement considers that inlet gate maintenance needs, bulkhead gate generally is arranged in the front.In construction time or maintenance
Phase considers that water blocking installation or maintenance unit need, and inlet gate, which is in, closes water blocking state, terminates in construction or turn(a)round, needs
When opening inlet gate progress unit has water debugging, unit guide vane, which cannot be in close state inlet gate sometimes and can not achieve, to be filled
Level pressure.The prior art generally closes water blocking using decentralization bulkhead gate, excludes water-filling using the filling valve at the top of inlet gate
Dynamic water unlatching inlet gate after water body more than valve water inlet, the prior art inlet gate little for conventional aperture height,
Because the water pressure that 2~4m differential water pressures that the water pressure that dynamic water opens door is operated normally with inlet gate generate is not much different, therefore intake
What gate operated normally open, and Men Li is able to satisfy moves water under the filling valve water inlet to gate ground sill head and open inlet gate and want
It asks.But for high narrow big aperture inlet gate, filling valve water inlet is higher to inlet gate ground sill head, some engineerings reach
20m, the Qi Menli operated normally well beyond inlet gate, need to increase headstock gear capacity can just open door, this will increase engineering
Investment, particularly with the more aobvious protrusion of hydroelectric project of porous mouth, and the probability very little that this kind of operating condition occurs when operating normally, it is
One unconventional operating condition, which increases opening and closing capacity, then seems very uneconomical, therefore the prior art is there is also deficiency, up for into one
It walks perfect.
Utility model content
The purpose of this utility model is that：A kind of high narrow big aperture inlet gate drainage arrangement is provided, by temporarily diving under water
Pump can exclude the water body between inlet gate and bulkhead gate substantially, open power to reduce inlet gate, meet and operate normally
Headstock gear capacity open inlet gate requirement, no replacement is required biggish inlet gate headstock gear capacity reduces cost of investment, from
And overcome the deficiencies in the prior art.
What the technical solution of the utility model was realized in：
A kind of high narrow big aperture inlet gate drainage arrangement of the utility model, including inlet gate and be located at inlet gate

In aforementioned device, the inspection platform is equipped with service aisle.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model is in inlet gate
Inspection platform upstream side in the middle part of open a rectangular recess, rectangular recess lower part be arranged a round hole pass to lower part bulkhead gate with
At the top of runner between inlet gate.In inlet gate and bulkhead gate water filling process, it can be placed by round hole interim latent
Water pump is by water outlet.This method can substantially reduce inlet gate and open power, and the headstock gear capacity for meeting normal operation opens water inlet
Gate requirement, without increasing inlet gate headstock gear capacity, effectively saves investment；It is equipped with hook at the top of rectangular recess, is used for
The iron chains of interim immersible pump is hung, the interim immersible pump of execute-in-place is convenient for；It is logical that rectangular recess is located at the work of inspection platform upstream side
Road top, do not influence the walking of operations staff, the effective guarantee safety of operations staff；Round hole pass to lower part bulkhead gate with
At the top of runner between inlet gate, exhaust velocity when bulkhead gate water-filling concora crush can be increased.
