Water irrigate ability and be widely distributed in China the earth, according to the demand of flood control, each barrage be required for set floodwater releasing port, mesh
Preceding barrage floodwater releasing port is that a unlimited bealock is opened up at the middle part of barrage or avris mostly, and this bealock can not only be made
Into the reduction of barrage reservoir storage, and isolate dam in itself, be unfavorable for safeguarding and pass through, on some barrages, people
The problem of reducing barrage reservoir storage in view of bealock, gate is also provided with bealock, but this valve is generally by people
Power or electric power are driven folding, it is necessary to which Attended mode, duty personnel is difficult to beat gate in the very first time after flood arrives
Open, so as to cause the even crevasse of unrestrained dam, therefore some hydraulic engineerings personnel wish that a kind of valving can be with dry season
More water storages, automatically turned on when flood breaks out, carry out flood diversion.
The content of the invention
Technical problem to be solved in the utility model is to provide the automatic flood discharge valving in a kind of water conservancy projects, solution
Existing barrage bealock flood discharge device reservoir storage of having determined is few and the problem of bealock provided with gate can not be opened timely.
In order to solve the above technical problems, technical scheme is used by the utility model：
A kind of automatic flood discharge valving in water conservancy projects, including check dam, check dam bottom, which is run through, is provided with drainage tube,
Drainage tube is located at check dam side and is provided with vertical valve port, and valve port is provided with valve ball, and valve ball passes through conduction chain and lever
Connection, lever one end is hinged with check dam, the other end is provided with adjustable ball float.
The bottom of the valve ball connects the top of the Anchoring chain, and the bottom of the Anchoring chain is fixedly connected with the valve
The bottom on doorway.
The section of the valve port is back taper or hyperbola.Corresponding valve ball is reverse taper or spheroid or oliva.
Discharge outlet is provided with relative to valve port one end on the drainage tube, discharge outlet is to favour horizontal line setting, and is inclined
Rake angle is 15 degree to 60 degree.
The bottom of the valve port is provided with air deflector.
The ball float is slidably located on lever by axle sleeve and locked by lock-screw.
Automatic flood discharge valving in a kind of water conservancy projects of the utility model, a circle is set by the side of check dam
Tubular valve doorway, valve ball is set on the top of valve port, and lever is connected by axle bed in the side of check dam, and in its intermediate part
Set chain to connect valve ball, connected in the other end of lever by axle sleeve and ball float, ball float automatic floating under flood high water level are set
Rise, drive lever to pull valve ball to depart from valve port, flood is discharged from valve port along drainage tube and discharge outlet, so as to realize the present apparatus
Flood discharge function.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of air deflector in the utility model.
In figure：Check dam 1, drainage tube 2, reservoir 3, valve port 4, discharge outlet 5, bearing block 6, lever 7, axle sleeve 8, ball float 9,
First tie point 10, conduction chain 11, the second tie point 12, valve ball 13, Anchoring chain 14, lock-screw 15, air deflector 16.
Embodiment
As shown in Figure 1-2, the utility model provides the automatic flood discharge valving in a kind of water conservancy projects, including check dam
1st, drainage tube 2, reservoir 3, valve port 4, lever 7, ball float 9, conduction chain 11, valve ball 13 and Anchoring chain 14, check dam 1 are one
Individual concrete wall, drainage tube 2 are a pipes, and drainage tube 2 runs through the bottom of check dam 1, and drainage tube 2 is located inside reservoir 3
One end conducting connection valve doorway 4, valve port 4 is perpendicularly fixed at the bottom of reservoir 3, and drainage tube 2 is located at one end outside reservoir 3
Provided with discharge outlet 5, the side on the top of check dam 1 is fixed with bearing block 6, one end of the support connection lever 7 of support base 6, lever 7
The other end it is chimeric be provided with axle sleeve 8, the bottom of axle sleeve 8 is fixed with ball float 9, and axle sleeve 8 can drive ball float 9 to be moved up in lever 7
It is dynamic, it is easy to the utility model to carry out the big minor adjustment of buoyancy, the middle part of lever 7 connects conduction chain 11 by the first tie point 10
Top, the bottom of conduction chain 11 connect valve ball 13 by the second tie point 12, and valve ball 13 is fitted together to the top of valve port 4, valve ball
