Water guide paddle wheel is the important feature of hydrogenerator, and modern design concept is then to use to be distributed on wing bone line
Singular point (source point, meeting point and eddy centre) is wing in runner grid to substitute, and is induced with undisturbed incoming flow and singular point series superimposed
Practical flow field of the substitution fluid around leaf grating is carried out in flow field, meanwhile, guarantee that wing contour is a closed stream line being superimposed in flow field, answers
Runner bucket is designed with potential barrier principle of stacking.
It during actual power, needs to introduce the water into spiral case, starches water flow to water guide by the guiding role of spiral case
Wheel is impacted, so that the rotation of water guide paddle wheel is driven, due to the inhomogeneities of water-flow equation in spiral case, so that water guide paddle wheel exists
The torque being subject to during rotation also tends to imbalance, usually larger in the side stress that water flow introduces, and uses for a long time
After be easy to cause equipment attrition deflection, the rotation of water guide blade is influenced, to influence generating efficiency.
Utility model content
For the above technical problems, the utility model provides a kind of hydrogenerator water guide paddle wheel, with solution
Equipment attrition skew problems caused by the moment unbalance that certainly existing water guide paddle wheel is subject to during by water impact,
The hydrogenerator can guide water flow according to the stress condition of water guide paddle wheel with water guide paddle wheel, improve water guide paddle wheel
Stress balance prolongs the service life.
The utility model provides a kind of hydrogenerator water guide paddle wheel, including vortex shell and rotation paddle wheel, the whirlpool
Stream girdle is connected with water inlet pipe, the rotation paddle wheel and the whirlpool around the periphery for being set to the rotation paddle wheel, the vortex shell
It is formed with cyclic annular diversion belt between stream shell, is provided with multiple shafts and multiple water conservancy diversion to circular array in the ring-type diversion belt
Plate, multiple deflectors are rotatably dispose in correspondingly in multiple shafts, and are provided with and can be fixed in the shaft
The positioning device of the deflector rotational angle, the rotation paddle wheel include inner ring, outer ring, multiple pressure sensors and multiple paddles
Leaf, multiple blades are around being set on the outer ring, and the inner ring is fixed setting, and the outer ring is rotatablely arranged at
The outside of the inner ring, multiple pressure sensors surround and are set between the inner ring and the outer ring, and multiple described
Pressure sensor is fixed on the inner ring, and the inner ring is internally provided with water outlet, and the outer ring is connected with for exporting
The output shaft of torque.
Further, corrosion-inhibiting coating is coated on the blade.
Further, the rotation paddle wheel is metal paddle wheel.
The utility model is provided with multiple pressure sensors between the inner ring and outer ring of the rotation paddle wheel, by multiple
Pressure sensor be able to detect that the rotation paddle wheel by inner ring described in water impact rotary course in different directions
The pressure being subject to, the pressure so as to be subject to according to different directions judge whether the rotation paddle wheel is in the shape of stress balance
State can correspond to adjustment and be set to leading in the cyclic annular diversion belt when finding that the rotation paddle wheel is in stress imbalance state
The rotational angle of flowing plate, to change the water-flow equation of the rotation paddle wheel periphery, and then to the not Tongfang of the rotation paddle wheel
Upward stress is adjusted, and is finally reached the effect of stress balance, advantageously reduces the rotation abrasion of rotation paddle wheel, and extension makes
Use the service life.
