Specific embodiment
As shown in Figures 1 to 4, the utility model includes at least one folding dam unit being arranged on the dam foundation 13, described
Fold the dam unit hydraulic cylinder 4 that includes quadric chain and be engaged with quadric chain, described quadric chain includes
The dam foundation 13, dam plate 1, connecting rod 2 and the push rod 3 being sequentially connected, the piston rod 41 of hydraulic cylinder 4 are connected with quadric chain.
Described dam plate 1, connecting rod 2, push rod 3 pass sequentially through chain connection；Hinge between described connecting rod 2 and push rod 3
Share with the piston rod 41 of hydraulic cylinder 4.I.e. connecting rod 2 shares a chain connection with the piston rod of push rod 3 and hydraulic cylinder 4.
Dam board support cage 8, push rod bearing cage 9 and hydraulic cylinders bearing cage 10 is provided with the described dam foundation, described
Dam plate 1 is arranged in dam board support cage 8 by dam board support 5, and push rod 3 is arranged on push rod bearing cage 9 by push rod bearing 6
On, hydraulic cylinder 4 is arranged in hydraulic cylinders bearing cage 10 by hydraulic cylinders bearing 7.Dam plate 1 can be poured by welding steel structure and concrete
Build and form, it is also possible to be welded by steelframe and steel plate, dam plate 1 is hinged with dam board support 5, dam plate 5 is by dam board support cage 8
It is fixed on dam foundation bottom surface；3 lower end of push rod is hinged with push rod bearing 6, and push rod bearing 6 is fixed on dam by push rod bearing cage 9
On basal surface, hydraulic cylinder 4 is fixed for hinge type, is hinged with hydraulic cylinders bearing 7, and hydraulic cylinders bearing 7 passes through hydraulic cylinders bearing cage
10 are fixed on bottom surface.
Between described dam plate 1 and dam board support 5, between push rod 3 and push rod bearing 6, hydraulic cylinder 4 and hydraulic cylinders bearing 7
Between be and be articulated and connected.
Between described adjacent dam plate 1, joint is provided with U-shaped sealing structure,
Described U-shaped sealing structure includes the sealing strip 11 for being wrapped in 1 side of dam plate and is separately positioned on sealing strip 11
Side and the press strip 12 of lower section, described press strip 12, are fixedly connected by bolt 13 between sealing strip 11 and dam plate 1.U-shaped sealing knot
Structure plays water-stopping seepage-proof effect.
The hydraulic pressure that each described folding dam unit is included at least two sets quadric chains and is engaged with quadric chain
Cylinder 4.Each folding dam unit includes two sets of quadric chains and two hydraulic cylinders, and two sets of quadric chains share a dam plate,
Dam plate can be rotated relative to fixed hinge on dam board support 5.Stretching out and shrink by hydraulic cylinder piston rod, drives double leval jib machine
Structure is moved, and using the deformability characteristics of quadric chain, makes quadric chain be deformed into different stablizing in different positions
Triangular structure, so as to realizing the folding flood passage of checkdam plate and launching retaining.
As shown in figure 1, solid line represents that double leval jib folds operating position of the dam plate 1 on dam under normal water retaining state in figure,
Dotted line represents that double leval jib folds dam and folding and the instantaneous position during expansion.
Dam plate 1 is from folding flood passage state to expansion retaining state conversion process：Hydraulic cylinder 4 under pressure piston rod to
Overhang, rotating around respective hinge axis of rotation, the thrust of hydraulic cylinder 4 is passed by connecting rod 2 and push rod 3 for drivening rod 2 and push rod 3
Dam plate 1 is passed, hinge axis of the dam plate 1 around dam board support 5 under the thrust of connecting rod 2 is rotated counterclockwise, so that dam plate 1
Water retaining height is gradually increasing；After the piston rod of hydraulic cylinder 4 is elongated to maximum position, hydraulic cylinder 4 can start pressure release, until being changed into
Normal not operating pressure, in 4 pressure leak process of hydraulic cylinder quadric chain in the presence of 1 gravity of dam plate and river pressure, dam plate 1
Certain angle is rotated clockwise, after the movable end of connecting rod 2 is contacted with the back side of dam plate 1, quadric chain is deformed into
Stable triangular structure, is played main support effect, so as to defining stable checkdam by push rod 3.
Dam plate 1 is from expansion retaining state to folding flood passage state conversion process：4 reverse pressurization of hydraulic cylinder, piston rod are inside
Shrink, 2 its hinge rotating shaft relative of drivening rod is rotated counterclockwise, the hinge axis of 3 relative push rod bearing 6 of push rod is rotated clockwise,
Dam plate 1 rotates counterclockwise a low-angle under the collective effect of connecting rod 2 and push rod 3 first, then rotates clockwise, water retaining height
It is gradually lowered；When the movable end of connecting rod 2 is contacted again with the back side of dam plate 1, quadric chain is deformed in order to another steady
Determine triangular structure, as shown in figure 3, mainly dam plate pressure is born by connecting rod 2, push rod 3 etc., hydraulic cylinder 4 does not stress.
The hydraulic cylinder 4 used by the utility model, dam plate 1 fell completely and its fully unfolded position under all do not stress, only
Need pumping plant to pressurize in the starting stage of jack-up process and process of falling, therefore can ensure that hydraulic system is safe and reliable, use the longevity
Life length.
The utility model can adopt hydraulic controlling pump work directly manually operated, it would however also be possible to employ simple electric control operation, may be used also
To adopt computer remote control system, can also be used in combination with buoy or the water-head such as infrared, flood passage of realizing falling automatically, block
The functions such as river retaining.
Preferred embodiment of the present utility model is the foregoing is only, not in order to limit the utility model, all in this practicality
Any modification, equivalent substitution and improvements that is done within new spirit and principle etc., should be included in protection of the present utility model
Within the scope of.
