Specific embodiment
As shown in Figures 1 to 4, the present invention includes the folding dam unit that at least one is arranged on the dam foundation 13, described folding
Folded dam unit includes quadric chain and the hydraulic cylinder 4 matching with quadric chain, and described quadric chain is included successively
The dam foundation 13, dam plate 1, connecting rod 2 and the push rod 3 connecting, the piston rod 41 of hydraulic cylinder 4 is 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 and the piston rod of push rod 3 and hydraulic cylinder 4 share a chain connection.
It is provided with dam board support cage 8, push rod bearing cage 9 and hydraulic cylinders bearing cage 10 in 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 passes through dam board support cage 8
It is fixed on dam foundation bottom surface；Push rod 3 lower end 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, 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 include being wrapped in dam plate 1 side sealing strip 11 and be separately positioned on sealing strip 11 top and
The press strip 12 of lower section, is fixedly connected by bolt 13 between described press strip 12, sealing strip 11 and dam plate 1.U-shaped sealing structure rises
To water-stopping seepage-proof effect.
Described each folds the hydraulic pressure that dam unit is included at least two sets quadric chains and matched with quadric chain
Cylinder 4.Each folds dam unit and comprises two sets of quadric chains and two hydraulic cylinders, and two sets of quadric chains share a dam plate,
Dam plate can rotate with respect to fixed hinge on dam board support 5.Stretching out and shrink by hydraulic cylinder piston rod, drives double leval jib machine
Structure moves, and using the deformability characteristics of quadric chain, makes quadric chain be deformed into different stablizing in different positions
Triangular structure, thus realize folding flood passage and the expansion retaining of checkdam plate.
As shown in figure 1, in figure solid line represents that double leval jib folds the operating position under normal water retaining state for the dam plate 1 on dam,
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 passes through connecting rod 2 and push rod 3 passes for drivening rod 2 and push rod 3
Pass dam plate 1, dam plate 1 rotates counterclockwise around the hinge axis of dam board support 5 under the thrust of connecting rod 2, 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 hydraulic cylinder 4 pressure leak process quadric chain in the presence of dam plate 1 gravity and river pressure, dam plate 1
Rotate clockwise certain angle, 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, thus define stable checkdam by push rod 3.
Dam plate 1 is from expansion retaining state to folding flood passage state conversion process：Hydraulic cylinder 4 reversely pressurizes, and piston rod is inside
Shrink, drivening rod 2 its hinge rotating shaft relatively rotates counterclockwise, the hinge axis of push rod 3 push rod bearing 6 relatively rotates 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 bearing dam plate pressure by connecting rod 2, push rod 3 etc., hydraulic cylinder 4 does not stress.
Hydraulic cylinder 4 used in the present invention, dam plate 1 fell completely and its fully unfolded position under all do not stress, only top
The starting stage playing process and process of falling needs pumping plant to pressurize, and therefore can ensure that hydraulic system is safe and reliable, long service life.
The present invention can be directly manually operated using hydraulic controlling pump work, it would however also be possible to employ simple electric control operation, can also adopt
Use computer tele-control system, can also be used in combination with buoy or the water-head such as infrared, flood passage of realizing automatically falling, barrage store
The functions such as water.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Any modification, equivalent substitution and improvement done within principle etc., should be included within the scope of the present invention.
