Power automatically-controlled shutter gate is China's hydraulic engineering technical staff after the painstaking efforts of more than 40 years, develops and possesses completely
A kind of energy-saving and environmental protection type gate of independent intellectual property right.From the birth of last century early sixties first generation hydraulic automatically-controlled shutter gate
It is raw, it successively have passed through four the double branch hinge types of transverse axis, branched hinge type, idler-wheel connecting-rod type and slide block type waterpower self-control type developing stage.
Hydraulic automatically-controlled shutter gate structure is relative complex at present, and flood passage resistance is larger, easily occurs just producing keying in running
Situation.And in the market substitute products such as the backwater gate cost such as steel dam, hydraulic pressure dam and maintenance cost is higher.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of waterpower self-control type flap gate, can be by hydraulic pressure
Deadweight with gate, which is realized, to be opened and closed automatically, and keying resistance is small, and flood passage resistance is small, safe and reliable to operation.
In order to solve the above technical problems, the technical scheme used by the utility model is：A kind of waterpower self-control type turnover panel
Gate, including steel-slag sand, the steel-slag sand include girder, secondary beam and panel, and the steel-slag sand bottom sets balancing weight, front support
Post and rear support strut one end are fixed in the concrete foundation of bottom, and the other end of forward support post is connected by rotating shaft with girder,
Steel-slag sand can be along axis of rotation, and the rear support strut is in vertical state, and panel upstream face is streamlined structure.
In preferable scheme, the rotating shaft is located at 1/3rd height and positions of steel-slag sand.
In preferable scheme, when the girder is with rear support strut upper-end contact, girder is in horizontality.
In preferable scheme, axle sleeve is set between the rotating shaft and forward support post.
In preferable scheme, the panel upstream face is bicircular arcs curvilinear structures, and two contact of a curve are at rotating shaft.
In preferable scheme, position and rear support strut top welding billet that the girder contacts with rear support strut,
Rubber blanket is set on the billet.
In preferable scheme, one end of the forward support post and rear support strut is connected with fixed column, and the fixed column pours
Inside concrete foundation.
A kind of waterpower self-control type flap gate provided by the utility model, has the advantages that：
（1）Steel-slag sand upstream face is streamlined, and horizontality is in during flood passage, and gate flood passage resistance is small.
（2）Steel-slag sand is rotatably connected by rotating shaft with forward support post, it is not necessary to which special turning device, structure is more
Simply, it is small to open and close resistance；When the discharge of river increases to design conditions, in the presence of water pressure, gate automatic turning, it is in
Flood passage state；When the discharge of river reduces, steel-slag sand under gravity, close, and overturns to dash state, lock by automatic turning
Push up overflow.
（3）One end of forward support post and rear support strut is connected with fixed column, and fixed column is cast in inside concrete foundation, knot
Structure is simple, and supporting construction flood passage resistance is small.
（4）The position and rear support strut top that steel-slag sand contacts with rear support strut set rubber blanket, reduce to steel-slag sand
Impulsive force, prevent the destruction to steel-slag sand.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is the structural representation of flood passage operating mode of the present utility model.
Fig. 3 is top view of the present utility model.
Fig. 4 is the curve synoptic diagram of upstream face of the present utility model.
Fig. 5 is rotating shaft of the present utility model and the connection diagram of girder and forward support post.
In figure：Steel-slag sand 1, forward support post 2, rear support strut 3, concrete foundation 4, rotating shaft 5, balancing weight 6, axle sleeve 7, steel pad
Plate 8, fixed column 9, girder 101, secondary beam 102, panel 103.
Embodiment
In Fig. 1 ~ 3, a kind of waterpower self-control type flap gate, including steel-slag sand 1, the steel-slag sand includes girder 101, secondary
Beam 102 and panel 103, the bottom of steel-slag sand 1 set balancing weight 6, and forward support post 2 and the one end of rear support strut 3 are fixed on bottom
Concrete foundation 4 on, the other end of forward support post 2 is connected by rotating shaft 5 with girder 101, and steel-slag sand 1 can be 5 turns along rotating shaft
Dynamic, the rear support strut 3 is in vertical state, and the upstream face of panel 103 is streamlined structure.
