Abstract
A water turbine comprises at least two annular wheel disks, a center shaft, spokes and a plurality of blades, wherein the center shaft is arranged at the center of the annular wheel disks, the axis direction of the center shaft is perpendicular to the radial directions of the annular wheel disks, the spokes are arranged between the annular wheel disks and the center shaft along the radial directions of the annular wheel disks, and the plurality of blades are mounted on the annular wheel disks in an encircling mode. Under certain working conditions, the efficiency of the impeller water turbine is directly proportional to the amount of the blades, so that the increasing amount of the blades can greatly improve working efficiency. According to practical data, the efficiency of a power generation device using the impeller water turbine is 1.4-1.5 times that of a traditional vertical shaft power generation device; besides, by means of buoyancy forces of the hollow main shaft, friction forces between the impeller water turbine and a bearing are reduced, and working efficiency is effectively improved; and the water turbine is applicable to reciprocating water currents and has the ability of self-starting under various flow rates.

Background technique
The trend water turbine of prior art has mainly been used for reference the technology of wind energy power, and be divided into two types: a class is that the impeller of horizontal axis water turbine is three blades or two blades, generally do not have huge air guide sleeve, but efficient is generally low; One class is to use for reference the wind power generation impeller of vertical shaft, the number of blade of this turbine impeller is three to five blades substantially, the turbine impeller that more than ten blade also arranged, basically be a traditional double click type impeller, efficient is higher a little than three blade hydraulic turbine impellers of horizontal axis, but will add huge air guide sleeve.
Energy worsening shortages now, greenhouse effect are serious day by day, and the energy day by day must low carbonization, so wind energy, ocean energy clean energy resourcies such as (comprising tidal energy, trend energy, wave energy, ocean current energy) is the developing direction of future source of energy.But the power generating equipment of these clean energy resourcies now, except the Wind Power Utilization comparative maturity, the utilization of ocean energy also all is in the starting stage, does not have general and ripe equipment, and equipment can not be changed on a large scale, and inefficiency does not still reach the level that is entirely satisfactory.
The model utility content
The utility model provides a kind of multiple-blade high efficiency water turbine at the deficiencies in the prior art.
For achieving the above object, the utility model can be taked following technical proposals: a kind of water turbine comprises at least two annular wheel discs, central shaft, spoke and a plurality of blade; Central shaft is arranged at the center of described annular wheel disc, and the axial direction of described central shaft is perpendicular to the radial direction of described annular wheel disc; Spoke is arranged between annular wheel disc and the central shaft, and described spoke is along the radial direction setting of annular wheel disc; A plurality of blades are around being located on the annular wheel disc; Blade quantity is minimum to be 28, mostly is the integer of the cms of annulus wheel dish external diameter circumference most; Described blade is arc, the summation of all blade arc length be annular wheel disc external diameter circumference 0.85-2 doubly between, the line segment angle of blade mid point to two end points constitutes leaf angle, described leaf angle is between the 100-170 degree; The maximum chord length line of blade is blade angle with the angle of the annular wheel disc radius of crossing the outer end points of blade, and described blade angle is between the 15-75 degree.
As preferably, described central shaft is hollow shaft.
As preferably, described water turbine also comprises two cover plates, and described two cover plates are arranged at described two annular wheel discs respectively back to a side of described blade.
The beneficial effects of the utility model are: under certain operating mode, and the relation that the efficient of impeller water turbine and the quantity of blade are directly proportional, blade quantity increases greatly increases work efficiency.Utility data shows that the electricity generating device efficient that adopts this impeller water turbine is 1.4-1.5 times of traditional vertical shaft electricity generating device efficient; Utilize hollow spindle self buoyancy in addition, reduced the frictional force of impeller water turbine and bearing, effectively improved working efficiency; Be fit to reciprocal current, and have the self-startup ability under the various flow velocitys.
