Background technology
The current flow-rate adjustment facility applied to water delivery engineering is mainly based on the equipment such as gates of segmental shape, flow regulating valve.It is such
The flow-rate adjustment mode of equipment controls for aperture, although control mode is simple, equipment operation is frequent, critical component rapid wear
Bad, maintenance cycle is short, influences water supply fraction.Secondly, the turbulent fluctuation of current extreme, mechanical oscillation are tight under high water head, heavy traffic condition
Ghost image rings safe to use.3rd, after current are by equipment, excess energy all dissipates, and causes energy waste.
The upstream water source of domestic water delivery engineering is mostly regulating reservoir, reservoir level cyclically-varying and excursion is larger,
In addition downstream user water demand also constantly changes, this make it that flow-rate adjustment facility operation operating mode is complicated, and single equipment is difficult to full
Sufficient service requirement.As domestic water delivery scale is increasing, similar engineering is more and more, safe and stable, economic carry out flow
Continuously adjust an important topic as water delivery engineering.
The content of the invention
The purpose of the present invention and provides a kind of continuous flow regulation system of water delivery engineering aiming at the deficiency of the prior art
System, it can be applied to, and water level luffing is big, in the changeable water delivery engineering of customer flow demand, it is safe and stable, economically into
Row continuous flow regulation, is an energy-saving water conservancy projects.
The technology solution of the present invention is as follows：A kind of continuous flow regulation system of water delivery engineering, it includes upstream height
Position water source, aqueduct, Francis turbine, axial flow hydraulic turbine, taper flow regulating valve, downstream user, flow controlling unit, its
In：The upstream high-level water source is equipped with water-level gauge, and the Francis turbine, axial flow hydraulic turbine and taper flow regulating valve upstream are equal
Equipped with flowmeter, the data acquisition end of the flow controlling unit is connected with the water-level gauge and the flowmeter, the flow
The control terminal of control unit and the Francis turbine governor, the axial flow hydraulic turbine governor and the taper tune stream
Valve switch board connects.
Francis turbine, axial flow hydraulic turbine and the taper flow regulating valve is arranged in parallel, can be high-order according to upstream
Water level, the downstream user amount of water required, various combination is carried out to equipment.Such as：Francis turbine isolated operation, axial-flow type
Hydraulic turbine isolated operation, flow regulating valve isolated operation, Francis turbine or axial flow hydraulic turbine and flow regulating valve cooperation etc..
The flow controlling unit gathers upstream high-level water source water level signal, downstream user traffic demand signal, respectively sets
The flow signal of standby flowmeter, exports to Francis turbine, axial flow hydraulic turbine and taper flow regulating valve control signal.
The beneficial effects of the present invention are：（1）Continuous flow regulation can be realized in the case of different water levels, it is defeated
Go out to meet the water of user demand, the water delivery engineering of customer flow demand complexity larger suitable for water level luffing.（2）It is logical
Cross between equipment and be arranged in parallel, can be spare each other when equipment breaks down, improve water supply fraction.（3）Adjust flow
During be able to can be generated electricity using high-level water source water, improve water utilization rate.
Brief description of the drawings：Figure of description is the structure diagram of the present invention.
