Description
Technical field
The invention belongs to field of fluid machinery, more particularly to one kind being driven by gear tidal power station blade adjustments machine
Structure.
Background technology
Currently, water pump both domestic and external or the hydraulic turbine have evolved to the form of regulating flow quantity from pervious constant flow,
Along with the development of field of fluid machinery, water pump is adjusted, the regulating mechanism of turbine blade also arises.
At this stage, on tidal power station using it is most be tubular turbine, the active wheel of tubular turbine be divided into for
Rotary propeller type and determine paddle, changing for runner bucket laying angle can be in the variation of wide range endoadaptation head and flow, and energy
Keep higher efficiency.In tidal power station daily management, operation, the feature that turbine blade should be made full use of adjustable, according to
Blade angle is adjusted flexibly in different service conditions, realizes optimization operation.
Blade adjustments have mechanical adjust to adjust two kinds with fluid pressure type in the prior art, with the development of the times, automation
Make rapid progress with digitized development, digital control mode is that the realization of automation plays basic role.All trades and professions are all
Develop towards digitized direction, but its achievement is also relatively immature.It is mechanical to adjust because there is lift axis, regulator shaft in operation
The problems such as holding fever or even scaling loss, work are less reliable；Fluid pressure type, which is adjusted, usually requires mating outer oil-servicing facilities, not only puts into
Height, maintenance management heavy workload, and also when because of work, system is outer inevitable for leaking, and has certain pollution to environment.
The inclained flow type water pump turbine blade wide-angle that patent publication No. is CN102367778A in the prior art moves paddle tune
Regulating device, the regulating mechanism are a space oblique leverage, and operating lever and crosshead move upwards a distance, and lower flexural pivot synchronizes
The distance is moved, then its sphere center position can be determined, and upper flexural pivot sphere center position can be determined, because of upper flexural pivot length it is known that connecting lever is around sharf
The radius of line rotation is it is known that then connecting lever rotation angle can determine, in this way, operating lever moves upwards, be changed into turning counterclockwise for blade
It is dynamic.Operating lever and crosshead are downward, vane clockwise rotation, in this way, the up and down motion of operating lever is changed into blade around itself axis
Forward and reverse rotation of line realizes that the wide-angle of blade is dynamic and adjusts that the inventive structure is simple, makes hydraulic turbine input power and pump output work
The adjustable range of rate greatly expands, but its blade adjustments angle is only limitted to positive and negative between 50 °, cannot be satisfied tidal power station flow
Change greatly the demand that blade rotating angle is adjusted under operating mode；A kind of high oil pressure control of Publication No. CN104879270A in the prior art
The electro-hydraulic adjusting method hydraulic turbine blades adjusting actuator of hydraulic turbine blades processed, which uses high oil pressure control system, according to water
A kind of fuzzy mathematical model for selection blade angle computation method that power station hydrological data and unit parameter are established.I.e. with head and
Changes in flow rate adjusts electro-hydraulic actuator by high oil pressure cntrol blade and adjusts runner blade to angle is calculated, and obtaining higher water can turn
Change efficiency, realizes the maximum target of high oil pressure cntrol blade angle fast regulating turbine-generator units annual electricity generating capacity.But its system according to
Rely in the long-term data of mathematical model and power station, implements certain difficulty, and run a series of equipment used, energy consumption
And control system is required for expensive cost, does not meet the energy-saving and emission-reduction that China vigorously advocates.
Invention content
For the more mechanical adjustment blade rotating angle of application is susceptible to the present situation of problems and examines in the world at present
Consider energy consumption etc., the present invention provides one kind being driven by gear tidal power station propeller regulating mechanism.The present invention installs
In impeller hub, as blade adjustments equipment, the needs of different leaves corner under different flow is met, intelligent apparatus is passed through
Axis rotation is twisted, drives gear drive that the fine tuning of blade full angle can be realized, and manual adjustment is very laborsaving, the present invention, which designs, to close
The advantages that reason, easy to adjust, good airproof performance is simple in structure, convenient to install and maintain, operates steadily, and balanced capacity is good；Also, it adjusts
Section blade angle only needs one man operation can be completed, and uses manpower and material resources sparingly.
What the invention is realized by the following technical scheme：
One kind being driven by gear tidal power station propeller regulating mechanism, including driven wheel of differential, drive bevel gear, locking
