Description
Technical field
The present invention discloses a kind of bulkhgead gate device for increasing root edge length using air bag and spring, is applied to water conservancy work
Journey field.
Background technique
In hydraulic engineering field, bulkhgead gate is the gate that can be closed in dynamic water, and main function is when unit or water
When accident occurs for road, channel is cut off rapidly by it, prevents peril from occurring or expanding, economic asset is avoided to lose.With
The design head of the development of hydraulic engineering, high basin dam is higher and higher, also higher to the performance requirement of bulkhgead gate.Slide block type is flat
Plate gate has the characteristics that structure is simple, cost is relatively low, operation operation is convenient and reliable, in hydraulic engineering more and more widely by
Using.In the big library of high dam, due to the influence of high water head, big vent flow, when soaking time is longer in water for slide block type bulkhgead gate
When, coefficient of friction increases, and bulkhgead gate, which closes goalkeeper, at this time will receive larger hydro-flow thrust, and gate is caused to occur closing badge resistance, close
Situation not in place.Traditional method is to increase gate counterweight, overcomes frictional force, bulkhgead gate space is smaller, can be used for counterweight
Limited mass.
Summary of the invention
Object of the present invention is to overcome deficiencies of the prior art, a kind of novel flat-plate valve system is provided, flat
Plate gate bottom increase can root edge structure outstanding, realize that root edge is stretched out and withdrawn, and increases lock by air bag and spring assembly
Door bears the effective area of water weight, to make gate by bigger vertical resultant force, the case where not increasing counterweight or few counterweight
Under overcome frictional force, make gate be easier realize close door.
Technical solution of the present invention
A kind of bulkhgead gate device is flat including being made of one group of stringer 2 and the mutually orthogonal storehouse 4 being divided into of one group of crossbeam 3
Lifting lug 1 is installed in plate gate panel, bulkhgead gate panel upper end；Increasing in the fluoran stream surface bottom of bulkhgead gate panel can bottom outstanding
Edge 11, the root edge is fixed on the leading edge in bottommost storehouse by shaft 10, while installing bullet in the inside in the corresponding storehouse of root edge 11
Spring 9 and air bag 8, the air bag is by snorkel 5 and bulkhgead gate panel external connection, 11 upper end aperture of root edge and be female connector ring
12, lower end 10 rotation, lantern ring 12 can be connect with one end of wirerope 6 around the shaft, and the other end of wirerope 6 bypasses the Flat Sluice shop front
Fixed guide ring 7 connects the hoist engine outside lock chamber on plate fluoran stream surface.
Bulkhgead gate utilizes water weight during closing door, and in the case where no prominent root edge, water weight active area is plate
The floor space in gate storehouse.Increase prominent root edge structure in bulkhgead gate fluoran stream surface bottom, is controlled by air bag and spring, make root edge
It can stretch out outside storehouse or withdraw in storehouse.Before increasing after prominent root edge, the bottom surface in bulkhgead gate storehouse is still under water weight, water pressure with
It is close when unmatched prominent root edge.Water body is divide into upper part and lower part by preceding prominent root edge, and the water body of medium root edge upper surface is in bulkhgead gate
It is kept essentially stationary during aerial drainage, upper surface pressure is larger, and the water body under root edge is since flow velocity is larger, according to Bernoulli Jacob's original
Reason, surface pressing is smaller when fluid flow rate is bigger, and following table surface pressure is smaller, therefore there are pressure differences for root edge upper and lower surface, generate
Water pressure straight down, at this time bulkhgead gate totality water pressure be bulkhgead gate orlop face water pressure and root edge water pressure this two
The sum of partial pressure increases the water pressure that flat bulkhgead gate is subject to by way of area increased.
The advantages of the present invention:
(1) after increasing prominent root edge, water weight effective active area is increased, closes door conducive to gate.
(2) root edge stretching can be realized by the structure of air bag and spring or withdrawn, structure is simple, easy for construction, cost
It is lower.

Specific embodiment
Embodiment 1:
With reference to the accompanying drawings and embodiments, specific implementation of the invention is described further.
As shown in Figure 1, a kind of novel flat-plate valve system, including lifting lug 1, stringer 2, crossbeam 3, storehouse 4, snorkel 5, steel wire
Rope 6, guide ring 7, air bag 8, spring 9, shaft 10, root edge 11 and lantern ring 12.
In bulkhgead gate opening-closing process, headstock gear holds lifting lug 1 by pull rod and realizes that gate is gone up and down.Bulkhgead gate panel by
One group of stringer 2 and the mutually orthogonal storehouse 4 being divided into of one group of crossbeam 3 form, and the lifting lug 1 is fixed on the upper end of bulkhgead gate panel.
When bulkhgead gate closes, as aperture reduces, horizontal force suffered by gate and water gravity increase simultaneously, and bulkhgead gate soaks in water
Coefficient of friction increases when the bubble time is longer, and when coefficient of friction is excessive, the vertical resultant force of bulkhgead gate can not overcome frictional force, at this time
Bulkhgead gate, which just will appear, to be closed badge resistance, falls the problems such as not in place.Conventional method is to carrying out counterweight in gate storehouse 4, in storehouse 4
Middle filling weight increases vertical resultant force.Storehouse 4 can be used for the finite volume of counterweight, when can not still frictional force be overcome by completely filling out,
Bulkhgead gate can not be just successfully closed.
The present invention bulkhgead gate fluoran stream surface bottom increase can root edge 11 outstanding, the root edge is fixed on by shaft 10
The leading edge in bottommost storehouse, while spring 9 and air bag 8 being installed in the inside in the corresponding storehouse of root edge 11, the air bag passes through snorkel 5
With bulkhgead gate external connection, 11 upper end aperture of root edge and be female connector ring 12, root edge lower end can 10 rotation around the shaft, pass through rotation
Can root edge 11 be stretched out and be withdrawn.6 one end of wirerope is connect with lantern ring 12, and the other end is around solid on bulkhgead gate panel fluoran stream surface
Fixed guide ring 7 connects the hoist engine (referring to fig. 2) outside lock chamber.
Original state air bag 8 is non-aerating, and lock chamber hoist engine pulls wirerope 6, is recovered to root edge 11 in storehouse, at this time spring
9 are pressurized.
Bulkhgead gate moves water and closes door, and when gate, which falls on certain aperture, can not continue to fall, hoist engine unclamps wirerope 6,
It is inflated by snorkel 5 into air bag 8, by the elastic force of spring 9 and the top power of air bag 8, root edge 11 is stretched out outside storehouse, is increased
The effective active area of water weight.
It after gate completely closes, is evacuated out of air bag 8 by snorkel 5, while lock chamber hoist engine pulls wirerope 6,
Root edge 11 is retracted in storehouse, realizes that root edge 11 recycles.
