Description
Technical field
The utility model relates to hydraulic and hydroelectric engineering field, the layering of specifically a kind of power station diversion tunnel water inlet is taken
Water-bound.
Background technique
In hydraulic and hydroelectric engineering, intake tower is the important building of generating system by piloting water, is related to generating system by piloting water, life
The operation of state water intaking and the pith of implementation and environmental protection.The water inlet of diversion tunnel is set in intake tower, due to
Large, medium and small type power station reference flow is larger, and it is a variety of that diversion tunnel has both sand washing, water supply, irrigation etc. before power generation, emptying, dam
Function, traditional diversion tunnel water inlet only designs one, positioned at the level of dead water of reservoir, does not fully consider the purposes of water intaking,
There are temperature of irrigation waters it is too low, silt sundries deposit is more the problems such as.
Currently, the intake tower of domestic power station stratified pumping uses steel construction more piece gate flap stoplog door, steel construction is folded
Liangmen is that more piece gate flap is composed, and the operation of steel construction Stoplog gate is complicated, and a section one is needed to save land lifting in the operation of different water levels,
Rolled steel dosage is more, and investment is high.
In addition, diversion tunnel reference flow is big, diversion tunnel is long, and pressure-bearing is high, in order to ensure generating system by piloting water is persistently pacified
Row for the national games, needs periodic inspection, so diversion tunnel also needs to take into account the needs of maintenance.
Utility model content
That the technical problem to be solved by the utility model is to provide a kind of operations is convenient, reduce investment outlay and easy access is drawn
Water tunnel water inlet layered water drawing structure.
The technical scheme adopted by the utility model to solve the technical problem is as follows: diversion tunnel water inlet stratified pumping knot
Structure, including intake tower, the tower body of intake tower is interior to be arranged intake chamber, and the upstream side of intake chamber is arranged below in reservoir operation scheme
Water gate, the upstream side setting of each water gate is not respectively set in equal intake, each intake at least two elevations
Trash rack, wherein the floor elevation of the minimum intake of elevation is higher than reservoir sedimentation elevation and is lower than dead water level elevation；Into
Bulkhead gate is arranged in the downstream side of sink, and bulkhead gate downstream side is equipped with venthole, passes through changeover portion at the downstream of bulkhead gate
Connect diversion tunnel.
Further, the intake at least three, intake chamber is in up-small and down-big shape, and intake is ladder-like arranged.
Specifically, the intake is three, respectively upper layer intake, middle layer water withdrawal mouth and lower layer's intake, upper layer
Height difference between intake and the bottom elevation of middle layer water withdrawal mouth is not less than 15m.
Specifically, the water gate is steel construction bulkhgead gate.
The beneficial effects of the utility model are: diversion tunnel water inlet layered water drawing structure uses fixed type steel reinforced concrete
Breast wall structure cancels steel construction Stoplog gate, and operation is convenient, reduces investment outlay.In different elevations, intake is set, it can be according to water need
It asks stratified pumping, such as irrigation water that shallow superficial water, town dweller's water supply is taken to take mid-water, improves and use water quality, guarantee reservoir
High-quality raw water can be quoted when different water levels.Bulkhead gate is arranged in the downstream side of intake chamber, convenient for the maintenance of diversion tunnel, thus
Guarantee the safe operation of generating system by piloting water.
Detailed description of the invention
Fig. 1 is the sectional side elevation of the utility model diversion tunnel water inlet layered water drawing structure embodiment.
Fig. 2 is 1-1 cross-sectional view in Fig. 1.
Components, position and number in figure: intake chamber 1, water gate 2, trash rack 3, bulkhead gate 4, venthole 5, mistake
Cross section 6, diversion tunnel 7；Massif 8, access bridge 9, original place upper thread 10；Level of dead water A, it normal pool level B, design flood level C, checks
Flood level D.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, the utility model diversion tunnel water inlet layered water drawing structure, including intake tower, the tower of intake tower
Setting intake chamber 1 in vivo, the upstream side of intake chamber 1, i.e. intake chamber 1 are arranged what at least two elevations did not waited close to the side of storage capacity
Water gate 2 is respectively set in intake, each intake, and trash rack 3 is arranged in the upstream side of each water gate 2.Intake is equal
Positioned in reservoir operation scheme B hereinafter, the elevation of each intake differs, to realize stratified pumping.Wherein, elevation is minimum
The floor elevation of intake is higher than reservoir sedimentation elevation and is lower than dead water level A elevation, the bottom plate of the minimum intake of elevation
Elevation also needs to reserve certain safe margin with water guarantee for the special time, and is determined according to the orographic condition of intake, makes to take
Mouth of a river floor elevation is lower than dead water level A elevation and has certain depth of the water submerging.
The downstream side of intake chamber 1 is arranged bulkhead gate 4, and 4 downstream side of bulkhead gate is equipped with venthole 5, under bulkhead gate 4
Diversion tunnel 7 is connected by changeover portion 6 at trip.Bulkhead gate 4 is used for the maintenance of diversion tunnel 7, to guarantee generating system by piloting water
Safe operation.The top of intake tower is connected with access bridge 9.
The quantity of intake, the i.e. number of plies of stratified pumping are determined according to reservoir scale.For example, intake is three,
Respectively upper layer intake, middle layer water withdrawal mouth and lower layer's intake, are ladder-like arranged.Upper layer intake and middle layer water withdrawal mouth
Floor elevation determines that height difference is not less than 15m between every layer of intake floor elevation, corresponding intake according to reservoir scale
Water gate 2 is steel construction bulkhgead gate, and the upstream of water gate 2 is trash rack 3.Intake chamber 1 is to be set in intake tower
Cavity, the intake of the upstream side setting stepped arrangement of cavity, downstream is vertical metope, therefore cavity is integrally in up-small and down-big
Shape, as shown in Figure 1.
