Description

Overflow bridge type barrage

Technical field:

The utility model belongs to the water engineering facility technical field, is a kind of overflow bridge type barrage.

Background technology:

In technique known, the barrage that is used for retaining on the middle-size and small-size river course has interlock type dam, rubber dam, and the problem that these two kinds of dams exist is: can not work as the bridge use, it is little to block the water yield.Especially rubber dam, though cost is low, not firm, easy damage and application life is short, maintenance cost is high.

Summary of the invention:

The purpose of this utility model provides a kind of overflow bridge type barrage that the water yield is big, use is flexible, sturdy and durable, bridge dam is dual-purpose of opening a sluice gate rapidly, block.

Realize that the technical scheme that the purpose of this utility model is taked is; This check dam is to be made of bridge dam and starting gate two parts, its main feature is: bridge dam is by bridge floor, bridge pier, the bridge dam base is formed, wherein, bridge floor is following spill, be provided with the starting gate of hydraulic pressure or pneumatic control in a side of spill bridge floor and bridge pier, this gate is by last, lower flashboard constitutes, adopt the flexible connection of radial type between each flashboard and the bridge pier, upper flashboard exceeds bridge floor, its two ends and bank protection contact position are provided with the Pingba mouth of a river, the lower flashboard bottom is provided with guide wheel, and place the guiding track that is provided with on the bridge dam base, the hydraulic cylinder or the cylinder that are used for the regulating gate switching are separately positioned on the adjoining bridge pier of each flashboard, are provided with the generating mouth of a river on the bridge dam base.

Overflow bridge type barrage according to such scheme is made both can hold the reservoir of laboring to river, solved town and country, two sides water along the river, can work as bridge usefulness again, mixed generating equipment, can also generate electricity.And hydraulic pressure or pneumatic starting gate by being provided with, make barrage open a sluice gate rapidly, not influence the drain off floodwaters energy of river course when flood season.Compared with prior art, it is big that this barrage blocks the water yield, opens flexibly, can retaining, can control drain discharge again, and long service life.

Utilize accompanying drawing to further describe embodiment of the present utility model below.

Fig. 1 is a bridge dam structural representation of the present utility model;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the state diagram when gate is opened in the utility model;

Fig. 4 is the sectional view of A-A among Fig. 2;

Fig. 5 goes up the lateral view that lower flashboard is connected with bridge pier in the utility model;

The specific embodiment:

Referring to Fig. 1, it is bridge dam of the present utility model, this bridge dam is made up of bridge floor 1, bridge pier 2, bridge dam base 3, wherein, bridge floor 1 is following spill, bridge dam base 3 is arranged to step, which is provided with generating mouth of a river 3a, is equipped with at generating 3a place, the mouth of a river to be used to close the hydraulic control at the mouth of a river or the sideboard (not shown) of gas control.

Referring to Fig. 2, be provided with the starting gate of hydraulic pressure or pneumatic control in a spill bridge floor 1 and a side of bridge pier 2, this gate is to be made of upper and

lower flashboard

5,6, adopt the flexible connection of radial type between each flashboard and the bridge pier 2, upper flashboard 5 exceeds bridge floor, in order to improve reserve-water-level, strengthens and blocks the water yield.Two ends and bank protection 4 contact positions at upper flashboard 5 are provided with the Pingba mouth of a river 7; Lower flashboard 6 bottoms are provided with guide wheel, and place the guiding track 9 that is provided with on the bridge dam base 3, and the hydraulic cylinder or the cylinder that are used for the regulating gate switching are separately positioned on the adjoining bridge pier of each flashboard.Label 8 among the figure is hydraulic cylinders that control upper flashboard 5 is opened, and is used to close the hydraulic cylinder of lower flashboard 6 or cylinder and is arranged on relevant position (not shown) on the contiguous bridge pier 2 of each lower flashboard.

Referring to Fig. 3, be the state diagram when gate is opened in the utility model.

Referring to Fig. 4, be the sectional view of A-A among Fig. 2.Between the first lower flashboard 6-1 and bridge abutment pier 2-1, be equipped with and open and close hydraulic cylinder 10 or cylinder.Corresponding mutually inclined-plane all is arranged at each lower flashboard 6 adjacent contact position, reaches the requirement that closure is blocked water by the inclined-plane interlock.

Referring to Fig. 5, be the lateral view that upper and lower flashboard is connected with bridge pier.In this case, the installation site of upper flashboard 5 and lower flashboard 6 specifically are to tilt to the direction of motion not on a vertical plane.The hydraulic cylinder 8 or the tilting bridge pier 2 that is installed in of cylinder that are used for jack-up upper flashboard 5; Dotted portion is represented the motion state of upper flashboard 5 when opening among the figure.

In the utility model, hydraulic control is adopted in the unlatching of gate, also can adopt pneumatic control, during hydraulic control, hydraulic pump, hydraulic control valve is installed in the workplace on Ba Qiao limit, connects by hydraulic line and respectively opens fluid cylinder.During gas control, air compressor, Pneumatic valve are installed in the workplace on Ba Qiao limit, connect by the tracheae line and respectively open cylinder.Hydraulic pressure or pneumatic connection belong to known technology, are not giving unnecessary details herein.

Retaining closed shutter operation: earlier lower flashboard 6 is from left to right interconnected, the first plate 6-1 is strained by hydraulically extensible cylinder 10 again, lower flashboard 6 each plate are closed tightly, upper flashboard 5 is arranged to certain gradient in vertical direction, under the gravity and the impulse force of water of self, close automatically tightly with lower flashboard 6.Close the generating mouth of a river baffle plate this moment, the water level of retaining is risen.

Operation is opened a sluice gate in draining: be the control drain discharge, earlier with plates in the middle of the upper flashboard 5 with fluid cylinder or cylinder jack-up, other upper flashboard jack-up, push up to upper flashboard 5 parallelly one by one with bridge floor 1, at this moment, retaining covers bridge floor and also together discharges from upper lock gate simultaneously.When water level is reduced to tail gates soon, open lower flashboard, under the effect of fluid cylinder 10 or cylinder, promote the first lower flashboard 6-1, make it back down a seam against the current, subsequently, other lower flashboard is under the impulse force of water, and edge guiding track 9 separately moves, and opens draining automatically.When closing, the promotion by the lower flashboard hydraulic cylinder of setting on the bridge pier 2 makes the lower flashboard return.
