Abstract
The invention discloses one kind for water conservancy diversion sand discharge apparatus before hydraulic structure, including training wall, baffle, lifter plate and disturbance module；The disturbance module arrangement is connect between training wall and baffle, and with baffle, and lifter plate can be risen and be landed by winch hoist, when lifter plate lands, be bonded with training wall and baffle.It includes two guide vanes to disturb module, and the both side surface of guide vane is three-dimensional two to pinch plane.This is reasonable for structure simple, disturbance module is fixed on baffle, with training wall keep certain mistake water distance from, disturbing module simultaneously is designed to three-dimensional two to pinch plane shape, increase turbulent water, be more likely formed spiral flow, lifter plate ensure that the flow of different flow directions can form spiral flow carrying by device and flow through, the silt mud before hydraulic structure is removed, to ensure hydraulic structure normal operation.
Description
Technical field
The present invention relates to training wall field, more particularly to a kind of bimodal current generates the sand discharge guiding device of spiral flow.
Background technology
Currently, training wall plays the role of more and more outstanding in hydraulic structure sand discharge, the silt that river is carried under one's arms is not only
Can deposit river, but also can cause to wear to device in important water resources industry such as power station, the workshop course of work.It leads
The effect of stream wall is the timely silt excluded before hydraulic structure, to keep the head difference of hydraulic structure upstream and downstream to keep not
Become, to ensure normal operating efficiency；Meanwhile training wall can also play the role of preventing river channel sedimentation, can promote to be formed
Spiral flow takes away silt, and preventing it from entering hydraulic structure working equipment influences normal use.However, training wall uses model at present
It is with limit, and design is chiefly used in unimodal current and generates spiral flow, sand-flash effect is also still limited to, and mud in river often can be still caused
Sand siltation, makes the river depth of water shoal, influences hydraulic structure and function；Accordingly, it is desirable to provide a kind of adjustable bimodal current
The sand discharge guiding device of spiral flow is generated, and before can be widely applied to hydraulic structure.
Invention content
The purpose of the present invention is that the device for providing a kind of adjustable bimodal current generation spiral flow water conservancy diversion sand discharge, solves
The technical issues of training wall can not be adjusted at present.
To solve the above-mentioned problems, the present invention provides a kind of technical solutions：
A kind of device for water conservancy diversion sand discharge before hydraulic structure, including training wall, baffle, lifter plate and disturbance module；
The training wall and baffle are vertically arranged in disturbance module in river in a manner of spaced and are fixed on baffle, with training wall
There is certain interval；The lifter plate is lifted and is landed by winch hoist, is bonded with baffle and training wall when falling.
Preferably, the diversion training wall and baffle are arc panel.The bending radius phase of the training wall and baffle
Together, bending direction is consistent.
Preferably, the disturbance module includes two guide vanes, the both side surface of guide vane is three-dimensional two to pinch plane, is led
One end of blade is fixedly connected with baffle, and the other end is free end, and there are gaps between being contacted with training wall.
Preferably, the height of the training wall will be less than baffle.
Bed material is started speed and is calculated using sinus state benevolence formula:
Wherein, △ indicates the roughness height of bed surface；δ is molecular film water thickness；ε0Force parameter is bonded to be comprehensive；γ0For bed
Face silt dry density；γ0 *For the stabilization dry density of sand grain, under normal circumstances, γ0=γ0 *；D and d*Respectively model and
Riverbed silt median particle diameter.
It can be seen from the above, in order to enable the device of the invention to play the role of water conservancy diversion sand discharge, it is necessary in model test
Meet model bed material and start speed, after according to the ratio of model bed material and practical riverbed sediment grain size, adjust suitable training wall
Depth-width ratio and disturb module two to the spacing between the curvature and guide vane of pinch plane, reach the startup speed of practical bed material.
Effective effect of the present invention：The present invention has reasonable for structure simple, and rolling open and close machine work realizes lifter plate
Raising and lowering, realizes the control that lifter plate forms different directions flow spiral flow, and plate rises to standard-sized sheet so that flow can
Directly along baffle and training wall interval, flowed through perpendicular to guide vane pinch plane, the spiral flow of formation can be with the silt of the walking apparatus area of coverage；
Plate drops to complete closure, is fitted closely with baffle and training wall, and flow can jump over from perpendicular to training wall upstream face direction at this time
Training wall forms spiral flow carrying to guide vane；Guide vane is arranged to three-dimensional two to pinch plane, utilizes spiral flow in pipes principle so that stream
It being disturbed by guide vane through flow and generates spiral flow, this setting more easily removes silt, shallow to have adjusted the depth of water in river,
Solve the problems, such as that siltation is serious.
Description of the drawings
The present invention is described in detail by following specific implementations and attached drawing for ease of explanation,.
Fig. 1 is the structural diagram of the present invention.
In figure：1, lifter plate；2, training wall；3, baffle；4, module is disturbed.
Specific implementation mode
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, several improvement and deformations can also be made, these improvement and deformations are also answered
It is considered as the limited protection domain of the application claims.
As shown in Figure 1, a kind of device for water conservancy diversion sand discharge before hydraulic structure, main includes disturbance module 4, further includes
Lifter plate 1, training wall 2 and baffle 3.
The training wall 2 and baffle 3 are vertically arranged in a manner of spaced in river, and disturbance module 4 is fixed on gear
On plate 3, there is certain interval with training wall 2；The lifter plate 1 is lifted and is landed by winch hoist, when falling and baffle
It is bonded with training wall.
Wherein, training wall 2 and baffle 3 are arc panel；Disturb module 4 include two guide vanes, guide vane be three-dimensional two to
Pinch plane.
When the lifter plate 1 lifts via winch hoist, by water (flow) direction and training wall 2 and baffle 3 plate
Face is parallel, vertical with the disturbance plate face of module 4, at this point, flow is directly influenced by two to the disturbance module 4 of pinch plane, generates radial
Acceleration causes flow carrying in the form of spiral flow to be discharged.
When the lifter plate 1 lifts via winch hoist, by water (flow) direction and training wall 2 and baffle 3 plate
Face is vertical, and flow is provoked by the upstream face of training wall 2, training wall of jumping over, and radial acceleration is generated through disturbing module disturbance, with spiral shell
The form carrying of eddy flow is discharged.
The above is that the adjustable bimodal current of water conservancy diversion sand discharge apparatus of the present invention generates the formation of spiral flow.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention, the technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
These principles of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, this
