Abstract
The utility model provides a speed-adjustable blade wheel used in liquid-power generating. The utility model comprises a blade wheel, a plurality of blades, a blade rotating shaft and a reset spring. The center of one side of the blade wheel is provided with polygon prisms which are corresponding to the number of the blades, taper holes are provided in the center of the polygon prisms, simultaneously a plurality of blade-reset final shafts which are corresponding to the number of the blades are is provided on the same side of the blade wheel. The blades are evenly provided on the blade wheel, the blade rotating shaft is provided in the position which is close to the central circular provided on the blade wheel, and one end of the blade is arranged with a blade axle-hole and a spring valve. The utility model has the advantages that the rotating speed is steady, the connection and the mounting and dismounting with the generator shaft are convenient.
Description
The utility model relates to a kind of impeller of fluid force generating usefulness, especially relates to a kind of variable-speed impeller of fluid force generating usefulness.
The impeller that existing wind-power electricity generation, hydroelectric power, steam turbine power generation are used, blade on it and impeller are fixing dead, when the fluid force power not simultaneously, blade can not correspondingly be shifted one's position or angle.The inventor is called in name in the file that " a kind of wind-driven generator wind wheel ", the patent No. are ZL92236459.1 and discloses a kind of wind wheel, fan blade on it can be adjusted angle with the wind-force size, though this wind wheel can more stably be controlled the rotating speed of generator, but only be applicable to wind generating unit, and be not suitable for hydroelectric installation, more can't make fluid force obtain recycling.
The purpose of this utility model is the variable-speed impeller that a kind of fluid force generating usefulness is provided at the deficiencies in the prior art.Blade on it can make the rotating speed of impeller keep stable with the hydrokinetic strong and weak angle that changes, and can be general in fluid force electricity generating devices such as wind-force, waterpower.
The purpose of this utility model is to realize by following technical solution.Design a kind of variable-speed impeller of fluid force generating usefulness, it comprises: impeller, a plurality of blades, blade rotor and Returnning spring; Described impeller one side center is provided with and the corresponding polygon prism of blade quantity, and the polygon prism center is provided with taper hole; Evenly be provided with in the same side of impeller and the corresponding a plurality of blades of the blade quantity terminal point axle that resets; Described blade is evenly distributed on the impeller, and blade rotor is arranged on close circle centre position on the impeller, and an end of blade is provided with blade axis hole and spring groove; Described Returnning spring is arranged in the spring groove of blade, and the one end is near blade, and the other end abuts against on the polygon prism.
In the such scheme, described blade, blade rotor, Returnning spring and the blade terminal point axle that resets respectively is 6, and the polygon prism that described impeller center is provided with is six prisms.
In the such scheme, the sectional shape of described blade is a semi-parabolic shape.
The variable-speed impeller of fluid force generating usefulness of the present utility model has the following advantages compared with prior art:
1, because blade and blade rotor place are provided with Returnning spring, can make the blade of given shape change position or angle with hydrokinetic difference, make it keep the optimum position, no matter how complicated the fluid force instantaneous variation is, can both make impeller with at the uniform velocity stable rotation, thereby guarantee the stable of generator speed.
2, this device is used for general environment, but stabilized (steady-state) speed is used for specific environment, but stabilized (steady-state) speed not only, and can make the fluid force recycling.
3, because impeller is provided with six prisms and taper axis hole, adopt compression fit to be connected between impeller and the generator shaft, make both connection easy accessibility, thereby guaranteed the quick mounting maintenance.
Below in conjunction with drawings and Examples, further specify the utility model.
Fig. 1 is the structural representation of the variable-speed impeller of fluid force generating usefulness;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is an I portion enlarged view among Fig. 1;
Fig. 4 is the schematic cross-section of blade among Fig. 1.
Fig. 1 to Fig. 4 illustrates the structure of most preferred embodiment of the variable-speed impeller of fluid force of the present utility model generating usefulness.Referring to figs. 1 through Fig. 4, the variable-speed impeller comprises: 1,6 blade 3 of impeller, blade rotor 2 and Returnning spring 5; Center, impeller 1 right side is provided with positive six prisms 8, and positive six prismatic 8 centers are provided with taper hole 7; Evenly be provided with 6 blades terminal point axle 6 that resets in the same side of impeller 1; Blade 3 is 60 ° of isogonisms and equidistantly is evenly distributed on the impeller 1, and blade rotor 2 is arranged on close circle centre position on the impeller 1, and an end of blade 3 is provided with blade axis hole 3-2 and spring groove 3-1; Returnning spring 5 is arranged in the spring groove 3-1 of blade 3, and the one end is near blade 3, and the other end abuts against on the spring arm of force 4 of positive six prisms.Blade 3 is hinged on the impeller 1 by blade rotor 2 and Returnning spring 5, and blade rotor 2 tops are provided with tapped hole 2-1, for preventing blade 3 and Returnning spring 5 axial floats, blocks and gets final product with screw, pad.When fluid force promoted blade 3, blade 3 was around blade rotor 2 rotations, and when fluid force was big, blade 3 can discharge most of fluid near the spring arm of force 4, and the limit position of rotation as shown in phantom in Figure 1; Fluid force hour, blade 3 can discharge the fraction fluid, thereby realize the purpose of stabilized (steady-state) speed near the blades terminal point axle 6 that resets.
In the such scheme, the sectional shape of blade 3 is a semi-parabolic shape.
