Description
Technical field
The present invention relates to a kind of high narrow down-the-hole planar slide emergency gate structure, belong to Hydraulic and Hydro-Power Engineering metal structure skill
Art field.
Background technology
In Hydraulic and Hydro-Power Engineering, protection of the planar slide emergency gate usually as unit water inlet passage or spilled water hole
Facility, the method for operation are that dynamic water closes door, and hydrostatic opens door, is added using water column or water column with reclosing door.For the type gate, gate
Panel is generally located on upstream side, and side sealing is arranged on the side column rear wing edge of downstream, and top seal is arranged on after the girder of top on the edge of a wing,
Gate bottom girder both sides are symmetrical arranged bottom seal supporting plate and upstream face plate composition door type structure, and bottom seal is arranged on door type structure
On, formed using the gate structure pattern for pushing up girder and bearing water column, this is for the moderate planar slide lock of the close head of the ratio of width to height
Door, gate can overcome to close gate resistance mechanical compliance profit and realize using water column pressure closes door, but for high narrower bore mouth planar slide gate, then it is sharp
Water column, which is born, with top girder realizes larger, the especially high narrow more aobvious protrusion of macropore port strobe of closing a difficulty, such as Sichuan Province great Du
River pillow dam one-level hydroelectric project, its water inlet emergency gate port size 6.5 × 15.54（It is wide × high）, design head
50.515m gate the ratio of width to height 6.5:15.54 are approximately equal to 0.418, bear water column and be not enough to overcome to close gate resistance power using girder is pushed up,
It need to add with 160t is weighed about, gate beam lattice domestic demand installs substantial amounts of counterweight, and cumbersome and cost is high, and economy is also poor, in addition,
The door type structure that bottom seal supporting plate and upstream face plate composition are symmetrical arranged in gate bottom girder both sides installs bottom seal because of side column
The interference of web and gate support plate, difficulty is also larger, so, prior art also Shortcomings, up for further perfect.
The content of the invention
It is an object of the present invention to provide a kind of high narrow down-the-hole planar slide emergency gate structure.Held using coxopodite gate flap
By water column, water column pressure can be increased, gate closes door without adding counterweight effectively to realize, can reduced investment outlay, and gate moves water and closes door
During, the fluidised form of current is preferable, is advantageous to the safety of gate operation.
Technical scheme：
A kind of high narrow down-the-hole planar slide emergency gate structure, the gate is by the epimerite gate flap, the section door leaf in one group that are sequentially connected
Formed with coxopodite gate flap；Lockplate is equipped with each gate flap；Epimerite gate flap is provided with water-filling equalizing valve and hanger；Epimerite gate flap
The downstream of gate flap is located at the panel of middle section door leaf；The bottom girder of coxopodite gate flap is box-structure, and bottom girder includes epiplastron
And bottom web, the upstream end of epiplastron and bottom web are connected with the rear edge of a wing, the lower front wing of the go forward edge of a wing and the bottom web of epiplastron
Edge is connected with bottom girder panel；The side column web and the rear edge of a wing of epiplastron and both sides form three side sealing in the upstream of gate and close knot
Structure；The edge of a wing is that whole board structure uses broken line or straight line pattern afterwards, and side sealing supporting plate in upstream is doubled as when the rear edge of a wing is linear pattern；Afterwards
Be connected when the edge of a wing is broken line type with being welded on the bottom seal supporting plate of bottom web bottom, and with horizontal line angle α >=45 °, side
Column web doubles as bottom seal supporting plate；Bottom seal uses the gate entirety water seal with right angle flanging, through bottom seal pressing plate and coxopodite
The bottom seal backbar connection of gate flap bottom.
In the foregoing narrow down-the-hole planar slide emergency gate structure of height, with being welded on bottom web when the rear edge of a wing is broken line type
The bottom seal supporting plate of bottom is connected, and doubles as bottom seal supporting plate with 60 ° of horizontal line angle, side column web.
In the foregoing narrow down-the-hole planar slide emergency gate structure of height, the bottom seal backbar include be welded on the rear edge of a wing and
Translot steel on side column web, translot steel both ends are welded with vertical slot steel, while vertical slot steel welds with the edge of a wing after side column web and side column
Connect.
In the foregoing narrow down-the-hole planar slide emergency gate structure of height, the bottom seal pressing plate is included positioned at the long horizontal of upstream side
Pressing plate and the hyphen pressing plate positioned at downstream both ends, long horizontal pressing plate both ends are connected through perpendicular pressing plate with hyphen pressing plate respectively.
In the foregoing narrow down-the-hole planar slide emergency gate structure of height, the bottom seal, bottom seal backbar, bottom seal pressing plate
It is provided with and matches somebody with somebody auger shell keyhole.
In the foregoing narrow down-the-hole planar slide emergency gate structure of height, the bottom girder panel is shaped as inner side rounding
Door type structure；Bottom girder panel is located at the downstream of coxopodite gate flap.
In the foregoing narrow down-the-hole planar slide emergency gate structure of height, the bottom web is provided with one group of leaking hole.
In the foregoing narrow down-the-hole planar slide emergency gate structure of height, the side column web bottom is provided with and side column web bottom
The cantilever support plate that outer rim flushes；One group of reinforcing plate is provided between cantilever support plate and side column web.
In the foregoing narrow down-the-hole planar slide emergency gate structure of height, in bottom girder panel both sides and bottom girder panel is arranged on
On internal partition on be both provided with into manhole.
By adopting the above-described technical solution, the present invention is compared with prior art, gate panel of the present invention is arranged on downstream
Side, the bottom girder of coxopodite gate flap use box-structure, bottom girder epiplastron not open-drain water hole and with both sides side column web and bottom master
The edge of a wing forms upstream three side sealing and closes structure after beam, and the edge of a wing is whole board structure after the girder of bottom, forms the lock that coxopodite gate flap bears water column
Door, considerably increases water column pressure, and gate need not add counterweight effectively to close door, greatly save investment.The present invention takes
The bottom seal supporting plate that the traditional bottom that disappears girder bottom web both sides are set, gate side column web double as bottom seal supporting plate, bottom seal
Using the gate entirety water seal with right angle flanging, it is easy to bottom seal installation, repair and maintenance, and reduces investment outlay, reduces two sides
The cavity that column web is formed with bottom seal supporting plate, gate move water and closed during door, and the fluidised form of current is preferable, reduces gate and shakes
It is dynamic, be advantageous to the safety of gate operation.Side column web bottom sets the cantilever support plate that is flushed with its outer rim, with preventing and bottom
The effect of water seal installation interference, cantilever support plate have the function that enhancing is stable using reinforcing plate.Epimerite gate flap, middle section door leaf and
Coxopodite gate flap both sides are respectively provided with lockplate, in order to in-site installation gate flap.With Sichuan Province Dadu River pillow dam one-level hydroelectric project
Exemplified by water inlet emergency gate, counterweight 160t is saved per fan brake door, equivalent to reducing investment outlay about 800,000 yuan.
