Description
Technical field
The invention belongs to hydraulic engineering equipment technical fields, and in particular to a kind of oblique branch jacking type downflow weir weir plate and the weir
The elevating method of plate.
Background technology
On traditional overfall dam, the lower energy almost all for sluicing stream is transported at the dam site of downstream, is bailed by underflow, face
Flow, choose stream etc. modes concentrate dissipation.The presence of energy dissipater's facility can effectively to it is lower sluice stream in energy carry out consumption and
Dispersion, more smoothes out when so that flow is entered downstream river course as much as possible, avoids down letting out current scour underwater bed and cause other
Harm.Prior art discloses a kind of oblique branch jacking type downflow weir, the downflow weir, hydraulic pressure rod piece directly acts on weir plate, leads to
The piston motion for crossing hydraulic pressure rod piece drives falling and standing for weir plate.For conventional outflow weir, novel downflow weir has water conservancy
Condition is more preferable, operation operation is more reliable, the more economical reasonable advantage of cost, but while weir plate water blocking, and crossing sluice stream will
It is let out to sole plate under the head of concentration is direct, even if the novel downflow weir is applicable in, head is low, and discharge capacity is limited, and crosses sluice
Flow discharge per unit width it is smaller, still the sole plate in structure can be caused to wash away and be vibrated, in the course of time influence operating condition and
Structural stability.
Invention content
Insufficient to solve the above-mentioned prior art, the purpose of the present invention is to provide a kind of new weir plate up-down modes to substitute
Weir plate under original hydraulic pressure rod piece piston motion drives falls and stands, and sluice stream was solved while mode changes and directly falls to base
Harm caused by plinth bottom plate.
The technical scheme is that：A kind of oblique branch jacking type downflow weir weir plate, including weir plate ontology, setting are on the weir
