Description
Technical field
The present invention discloses a kind of hydraulic gate structure of adjustable lower suction, is applied to hydraulic engineering field.
Background technique
In hydraulic engineering, with the construction of high basin dam, the working head of bulkhgead gate is gradually increased, such as 1 grade of water of silk screen
Power station working head 130m, Xiaowan Hydropower Station working head 160m, La Xiwa power station working head 165m etc..Bulkhgead gate exists
After being soaked for a period of time in water, the abrasion of getting rusty that sliding block, side wheel and water seal etc. all can be different degrees of causes coefficient of friction relatively to design
Shi Mingxian becomes larger.When bulkhgead gate carries out closing in dynamic water, it is easily more than opening and closing that the gate initial stage lasting force that falls is often excessive
Machine capacity, damages headstock gear；And when gatage is smaller, the hydro-flow thrust being subject to is larger, if gate closes door
Power can not offset frictional force, just will appear the phenomenon that closing badge resistance, can not closing, bring very big security risk.Traditional method
It is to increase gate counterweight, so that it is overcome frictional force, and bulkhgead gate space is limited, it is limited to can be used for increased counterweight, increases simultaneously
After adding gate counterweight, gate whereabouts initial stage lasting force is bigger, is easier to cause to damage to headstock gear.
Summary of the invention
In view of this, the invention discloses a kind of hydraulic gate structure of adjustable lower suction, gate base cross members into
Row aperture reduces water weight forced area, and gate whereabouts initial stage lasting force is made to be unlikely to excessive；Covering plate structure is added, when gate is small
When aperture can not close, the cover board on the upside of base cross members is fallen and covers aperture, increased the forced area of water weight, that is, increase down
Suction closes door conducive to gate realization.
Technical solution of the present invention
A kind of hydraulic gate structure of adjustable lower suction, including cover board drag-line, permeable hole, cover board, guide rail, support ring,
Aperture, root edge, longitudinal and cross beam, the bulkhgead gate are made of a series of crossbeams and stringer, are equipped with and are opened on the crossbeam of bottommost
Liftable cover board is arranged in hole above aperture, and cover board is suspended in midair by cover board drag-line, is equipped with smooth lead in the four corners of crossbeam beam lattice
Rail, cover board is constrained when falling by guide rail, and accurately covers aperture.
Further, support ring is installed in aperture, is used to support cover board and seal and opening.
Further, the position of the longitudinally opposed cover board of each crossbeam of gate is equipped with permeable hole, the cover board of connecting cover plate
Drag-line is reached above gate by permeable hole, the hoist engine on ground is connected to, for driving cover board to go up and down.
Further, the four corners of the cover board position opposite with guide rail is equipped with through-hole, and aperture is slightly larger than guide rail, and guide rail runs through
In corresponding through-hole, so that cover board is accurately fallen in support ring when declining, cover aperture.
Further, root edge is extended to form to bottommost crossbeam lower part in each stringer of bulkhgead gate.
The advantages and positive effects of the present invention:
(1) when bottommost header board aperture, bulkhgead gate close, gate lasting force can be reduced in larger opening.
(2) aperture is covered by falling cover board when small guide vane can not continue to fall, increases bottom transverse by bulkhgead gate
The forced area of beam slab, it is possible to increase lower suction.
(3) by setting guide rail, so that cover board is fallen along guide rail, accurately cover aperture.
(4) by setting rubber ring, header board will not be damaged when falling cover board, while having the function of water shutoff.
Detailed description of the invention
Fig. 1 is the structural schematic diagram；
Fig. 2 is the internal cross section figure.
In figure: 1, cover board drag-line；2, permeable hole；3, cover board；4, guide rail；5, support ring；6, aperture；7, root edge；8, stringer；
9, crossbeam.
Specific embodiment
With reference to the accompanying drawings and embodiments, specific implementation of the invention is described further.
By attached drawing 1 and attached drawing 2 it is found that the hydraulic gate structure of the adjustable lower suction of the present invention, including cover board drag-line 1, thoroughly
Water hole 2, cover board 3, guide rail 4, support ring 5, aperture 6, root edge 7, stringer 8 and crossbeam 9.
Bulkhgead gate is made of a series of crossbeams 9 and stringer 8.Bulkhgead gate moves water and closes door, inhales under gate in big aperture
Power is larger, is easily more than headstock gear capacity；And a power deficiency is closed when small guide vane, it easily leads to gate and closes badge resistance.To bulkhgead gate into
Row optimization, opens up 4 apertures 6 in bulkhgead gate bottommost crossbeam 9, a series of liftable cover boards 3 is arranged above aperture 6,
Cover board 3 is suspended in midair by cover board drag-line 1.The position longitudinally opposed with cover board 3 is designed with permeable hole 2 on each crossbeam 9 of gate, connection
The cover board drag-line 1 of cover board 2 is reached above gate by permeable hole 2, is connected to the hoist engine on ground, and ground hoist engine pulls cover board
Drag-line 1 lifts cover board 3.By 3 pull-up of cover board, expose aperture 6, the setting of aperture 6 reduces the water weight area of crossbeam 9, solves
Gate is when big aperture is closed, suffered lasting force excessive problem；When cover board 3 is fallen, cover board 3 blocks aperture 6, at this time
The water weight area for increasing crossbeam 9 solves the problems, such as to close door when gate small guide vane hypodynamic.
Support ring 5 is installed along aperture 6, support ring 5 is made using rubber material, plays support and sealing function.In crossbeam 9
Top arranges that cover board 3, cover board drag-line 1 hang cover board 3 through permeable hole 2, and cover board 3 is suspended under time bottom cross beam 9.In order to make to cover
Plate 3 accurately covers aperture 6, in the fixed smooth guide 4 of the four corners of 9 beam lattice of crossbeam, while in the four corners aperture of cover board 3, hole
Diameter is slightly larger than guide rail 4, is constrained when cover board 3 falls by guide rail 4, can accurately fall in support ring 5, cover aperture 6.
Bulkhgead gate closes in front of the door, and hoist engine drives cover board drag-line 1 to rise, and cover board 3 is made to be raised to time 9 lower end of bottom cross beam, exposes
Aperture 6 and support ring 5.Bulkhgead gate starts dynamic water and closes door, and bulkhgead gate and cover board 3 fall simultaneously, and cover board 3 is still at this time
Secondary 9 lower end of bottom cross beam.When bulkhgead gate, which falls on small guide vane, further to fall, hoist engine puts down cover board 3, falls on support
On ring 5, aperture 6 is covered, increases the forced area of minimum header board, increases suction under gate, gate continues to close at this time
Door, until closing.
