Description
Technical field
The utility model is related to a kind of regulating dams, belong to hydraulic engineering field.Manual operation, suitable for there is higher landscape to want
The city river regulation and control river discharge asked.
Background technology
Regulating dam is to adjust water levels of upstream and downstream and control the hydraulic structure of water flow on river, and gate opening/closing is
The most important working link of regulating dam.The hoisting capacity of gate includes mainly 2 parts, when the dead weight of gate, second is that upstream and downstream
Frictional force between water gate caused by water-head and sluice pier wall.Gate hoist can be divided into machinery by power transmission mode
Transmission and hydraulic drive；It can be divided by the installation situation of headstock gear fixed and mobile；By gate and gantry crane connection type
Flexible, rigidity and varied rigid link can be divided into；It is divided into plane gate headstock gear, gates of segmental shape headstock gear by the feature classification of gate
Machinery etc. is operated with miter gate.The force of opening and closing of regulating dam is generally all very big, needs special dynamical system.
Existing regulating dam is generally made of lock chamber, upstream linkage section and downstream connection section.Lock chamber have bottom plate, gate,
Headstock gear, gate pier, breastwork, service bridge, access bridge etc., upstream linkage section have upstream anti-scour trench, bedding, aileron, upstream slope-protection etc.,
Downstream connection section has protection-apron, Heyman, downstream anti-scour trench, aileron, downstream protection slope etc..In addition, the management house that there is a need to and power supply
Facility.Construction investment is big, takes up a large area, and operation energy consumption is big, and maintenance requirement is high, and more unfavorable shadow is caused to urban landscape
It rings.
Invention content
The utility model is insufficient present in construction and use for existing regulating dam, provide it is a kind of it is simple in structure, open
Close the regulating dam that laborsaving, operation and maintenance are easy, landscape effect is good.
Realize that the technical solution of the present utility model purpose provides a kind of regulating dam, it includes dividing plate, upper layer chest
Wall, lower layer shut off wall, lock hole and gate；The upper layer breastwork is set to one end of dividing plate, and wall crest elevation is higher than upstream highest
Water level；The lower layer wall that shuts off is set to the other end of dividing plate, and foundation is fixed in riverbed；The face of the dividing plate is high
Journey is less than upstream and downstream lowest water level, is provided with circular hole in dividing plate, the circular hole of dividing plate is fixed in the lock hole of circular tube shaped vertically
On, several water outlets are uniformly distributed on the tube wall in lock hole, lock hole top is with upper layer breastwork with high；The gate is circular tube shaped,
It is placed in lock hole with dynamic fit clearance, water outlet corresponding with lock hole tube wall is distributed on the tube wall of gate, gate uses floating body material
Material, or by setting floating body, or be cavity, so that its whole unit weight is slightly less than 1.
In technical solutions of the utility model, safe anti-falling grid is additionally provided at the top of gate.
Compared with prior art, the beneficial effects of the utility model are：
1. the ingenious construction of the utility model is that as long as minimum hoisting capacity achieves that any opening degree of gate, no longer
Need power plant.The dead weight of gate is by the buoyant equilibrium of its own；Due to the lateral hydraulic pressure suffered by each gate flap of gate pipe
Power is all radial, resultant force zero, therefore, the frictional force between water gate caused by water levels of upstream and downstream difference and lock hole pier wall
Also it is zero.
2. the superstructure scale of construction of the utility model is small, lock hole pipe multidirectional outlet stream, and can be layered as needed at one piece
Several lock hole pipes are arbitrarily arranged on partition board, can obtain good landscape effect.
3. the utility model solves problems of the prior art, provide it is a kind of can very easily manpower opens and closes
Regulating dam, gate pipe flexible rotating, that is, controllable water flow.With good investment, land used saves, and operation and maintenance are easy, landscape effect
It is good.

Embodiment 1
Referring to attached drawing 1, it is a kind of structural schematic diagram of regulating dam provided in this embodiment；Regulating dam includes dividing plate
1, upper layer breastwork 2, lower layer shut off wall 3, lock hole 4 and gate 5.1 face elevation of dividing plate is less than upstream water level 7 and the level of tail water 8,
And the requirement of the landscape depth of water is taken into account on downstream tier partition board, upper layer breastwork 2 and lower layer, which shut off, is provided with circle in the dividing plate between wall 3
Hole；Upper layer breastwork is set to dividing plate front end, and wall crest elevation is higher than maximum head water；Wall is shut off after dividing plate in lower layer
End, foundation are fixed in riverbed 9；Make lower water column that can only be flowed up by the circular hole in dividing plate；Lock hole 4 is vertical solid
The pipe being scheduled in dividing plate, tube bottom are directed at the circular hole on partition board, and pipe side is uniformly distributed several water outlets, tube top and upper layer chest
Wall is the same as high；Gate 5 is also pipe, and outer diameter is identical with lock hole round tube inside diameter, between retain and move fit clearance, the pipe side of gate is divided
Cloth and corresponding water outlet on the pipe of lock hole, tube top lay safe anti-falling grid 6, and gate pipe is made by the way that floating body or cavity is arranged
Its whole unit weight is slightly less than 1.As long as the minimum hoisting capacity of the keying of gate, manpower can easily realize any opening degree of gate.
Referring to attached drawing 2, when the water outlet in lock hole 4 and gate 5 mutually staggers, regulating dam is closed.
Referring to attached drawing 3, it is the overlooking structure diagram in the regulating dam holes open state Xia Zha and gate.When lock hole 4 and lock
When the water outlet of door 5 is corresponding, regulating dam is in open state.
