Description
Technical field
The utility model discloses a kind of use magnet driving root edge bulkhgead gate device outstanding, is applied to hydraulic engineering and leads
Domain.
Background technique
In hydraulic engineering field, the main function of bulkhgead gate be when accident occurs for unit or water channel, can be in dynamic water
The gate of middle closing cuts off rapidly water flow by it, prevents peril from expanding, economic asset is avoided to lose.As high basin is big
The construction on dam, design head is higher and higher, slide block type bulkhgead gate have structure is simple, operation run convenient and reliable, cost compared with
Low feature is applied more and more widely in hydraulic engineering.Plate emergency gate in dynamic water can normal switching-off, and
Its hydrodynamic characterisitic during the shutdown process, be gate design and use in focal issue of interest.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, coefficient of friction increases, at this time
Bulkhgead gate, which closes goalkeeper, will receive larger hydro-flow thrust, and gate is caused to occur closing a difficult situation.Traditional method is to increase
Gate counterweight overcomes frictional force, but bulkhgead gate space is smaller, can be used for the limited mass of counterweight.
Utility model content
The utility model aim is to overcome existing bulkhgead gate above shortcomings, provides a kind of root edge protruding-type plate
Valve system, bulkhgead gate bottom increase can root edge structure outstanding, pass through electromagnet and spring and realize that root edge is stretched out and received
It returns, increases gate and bear the effective area of water again, to make gate by bigger vertical resultant force, do not increasing counterweight or lacking
Frictional force is overcome in the case where counterweight, so that gate is easier realization and is closed door.
The technical solution of the utility model
A kind of root edge protruding-type bulkhgead gate device, a series of storehouse 4 including being divided by stringers 2 and crossbeam 3 form plate
Gate panel is equipped with lifting lug 1 in the upper end of bulkhgead gate；Increasing in the fluoran stream surface bottom of bulkhgead gate panel can bottom outstanding
7 structure of edge, root edge 7 are made using iron plate, and the leading edge of bulkhgead gate panel bottom, bulkhgead gate panel are mounted on by shaft 8
Electromagnet 6 is installed in the storehouse of bottom position, it is each between the root edge 7 and orlop of 6 both ends corresponding position of electromagnet to fix a pressure
Contracting spring 5.
Bulkhgead gate utilizes water weight during closing door, and in the case where no prominent root edge, water weight active area is gate
The floor space in storehouse.Increase prominent root edge structure in bulkhgead gate fluoran stream surface bottom, is controlled by electromagnet and spring, enable root edge
It is enough to stretch out or withdraw.After preceding prominent root edge stretches out, the bottom surface in gate storehouse is still under water weight, water pressure with without prominent root edge phase
Closely；Water body is divide into upper part and lower part by prominent root edge, and the water body of medium root edge upper surface is kept substantially during gate aerial drainage
Static, upper surface pressure is larger, and the water body under root edge is since flow velocity is larger, according to bernoulli principle, when fluid flow rate is bigger
Surface pressing is smaller, and following table surface pressure is smaller, therefore root edge upper and lower surface generates water pressure straight down there are pressure difference,
Gate totality water pressure is the sum of gate orlop face water pressure and root edge water pressure this two parts pressure at this time, passes through area increased
Mode increase the water pressure that gate is subject to.
The advantages of the utility model and the utility model has the advantages that
(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 electromagnet and spring or withdrawn, structure is simple, and easy for construction, cost is lower.

Specific embodiment
Embodiment 1:
With reference to the accompanying drawings and embodiments, the specific implementation of the utility model is described further.
As shown in Figure 1, a kind of root edge protruding-type bulkhgead gate device, including lifting lug 1, stringer 2, crossbeam 3, storehouse 4, compression bullet
Spring 5, electromagnet 6, root edge 7 and shaft 8.
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 is by a system
The storehouse 4 that column stringer 2 and crossbeam 3 are divided into forms, and the lifting lug 1 is mounted on the upper end of bulkhgead gate.When bulkhgead gate closes, with
Aperture reduce, horizontal force and water gravity suffered by bulkhgead gate increase simultaneously, and bulkhgead gate rubs when soaking time is longer in water
It wipes coefficient to increase, when coefficient of friction is excessive, the vertical resultant force of bulkhgead gate can not overcome frictional force, and bulkhgead gate will go out at this time
It now closes badge resistance, fall the problems such as not in place.Conventional method is that weight is inserted in storehouse 4 to counterweight is carried out in gate storehouse 4, is increased
Big vertical resultant force.Storehouse 4 can be used for the finite volume of counterweight, and when can not still frictional force be overcome by completely filling out, bulkhgead gate is with regard to nothing
Method is successfully closed.
The utility model bulkhgead gate fluoran stream surface bottom increase can 7 structure of root edge outstanding, root edge 7 use iron plate system
Make, the leading edge of bulkhgead gate fluoran stream surface bottom is mounted on by shaft 8, electricity is installed in the storehouse of bulkhgead gate fluoran stream surface bottom position
Magnet 6, it is each between the root edge 7 and orlop of 6 both ends corresponding position of electromagnet to fix a compressed spring 5 (referring to fig. 2), initially
State electromagnet 6 is powered, and electromagnet 6 is integrated with the suction of root edge 7, and compressed spring 5 is pressurized (referring to Fig. 3) at this time.Bulkhgead gate is dynamic
Water closes door, and when bulkhgead gate, which falls on certain aperture, can not continue to fall, electromagnet 6 is powered off, and electromagnet 6 and root edge 7 separate, and leads to
The elastic force of overcompression spring 5 makes 8 rotation around the shaft of root edge 7, realizes that root edge 7 is leant out, increases the effective active area of water weight.
After bulkhgead gate completely closes, electromagnet 6 is powered, and merges electromagnet 6 and root edge 7 again, root edge 7 is around the shaft
8 reversely rotate, and realize that root edge 7 is withdrawn.
