Embodiment
According to Fig. 1, Fig. 2, shown in Figure 6, on basis, fan main body ground 25, by fan main body wind deflector 22, top layer upper cover plate 11, interlayer dividing plate 18, bottom panel 24, structural connection 2 is connected with hollow vertical axial wall 1, forming a centre is pillar by barrel-shaped hollow vertical axial wall 1, the main body wind deflector 22 of peripheral arc is the frame-type structure of support, by structural connection 2, fan main body top layer upper cover plate 11, the be connected frame-type structure of a formed stable tier rack type with very good wind resistance power performance of bottom panel 24 and mesosphere dividing plate 18.
As shown in Figure 3, the angle of utilizing blower fan external rotor cantilever 15 fan blades 16 to rotate is controlled the size of the wind-engaging sectional area of fan blade 16, and changes the wind-force that is subjected to of fan blade 16; Fan blade 16, when wind speed exceeds rated wind speed, can by around external rotor cantilever 15, on fan blade running shaft 13 turn an angle to change the size of the wind-engaging sectional area of fan blade 16, thereby change the size that is subjected to wind-force, improve the wind loading rating of the moving system parts such as fan blade 16 with this, prevent that the moving system parts such as fan blade 16, internal rotor 17, external rotor 20 are former thereby damage because of stall, overload etc.
Such as Fig. 2, shown in Figure 4, utilization is fixed on external stator coil 4 external stator cores 5 on generator inner-stator iron core 6, inner stator coil 7 and the external rotor 20 on the hollow vertical axial wall 1, drive transmission systems 3 with being rotated by the external rotor 20 that slowly runs, make generating electricity with the internal rotor 17 speedup quick rotation of the generator magnetic pole 19 of permanent magnet between hollow vertical axial wall 1 and the external rotor 20.Utilize and be fixed with generator inner-stator iron core 6, inner stator coil 7 on the hollow vertical axial wall 1, fixing external stator coil 4 on external rotor 20 walls, locate rotor iron core 5 and driven by transmission system 3 speedups by the external rotor 20 that slowly runs, be provided with internal rotor 17 between hollow vertical axial wall 1 and the external rotor 20, on the inside and outside wall of internal rotor 17 with the generator magnetic pole 19 of permanent magnet, internal rotor 17 quick rotation and generate electricity (because wind-driven generator fan rotor rotation speed too low can't the direct generation of electricity).Generator casing, generator shaft, bearing, fan etc. have been saved.And Bian just can solve because of the unstable problem that can't be incorporated into the power networks of the unstable generating frequency that causes of rotation speed of fan with the generator designs of brushless double feed variable speed constant frequency.Generator on blower fan external rotor 20 walls, electricity can be able to directly supply with on the control system equipment of the moving element such as fan rotor.So namely solve the power transmission problem between blower fan and the generator, also solved the power supply problem of blower fan moving element control system and the heat dissipation problem of generator.When having saved generator casing, generator shaft, bearing, fan etc., electric generator structure also becomes integrated combined-type, can be greatly, can urinate and install in producing.Under the acting in conjunction of horizontal and vertical magnetic-levitation, the Variable roll frictional resistance is air sliding friction resistance, has reduced the rotational resistance of blower fan internal rotor 17, external rotor 20.
Formed by some block permanent magnets such as Fig. 2, internal rotor magnetic-levitation system shown in Figure 48, be separately positioned on the inwall of the outer wall of hollow vertical axial wall 1 and internal rotor 17 and the horizontal and vertical magnetic suspension mechanism of looping on the two ends of internal rotor 17 and the structural connection 2; External rotor magnetic-levitation system 10 is comprised of some block permanent magnets, is separately positioned on the horizontal and vertical magnetic suspension mechanism of the corresponding position looping of interlayer dividing plate 18 or bottom panel 24, top layer upper cover plate 11 and wind gathering cover 14; Internal rotor 17, external rotor 20 consist of gear by transmission system 3, make the generator magnetic pole 19 speedups generating of internal rotor 17.
Shown in Fig. 1, Fig. 2, Fig. 3 structure, utilize the frame structure of tier rack type wind-guiding template can make the multi-deck combined structure, to increase the electric motor power of complete machine.The upper and lower layer structure that is made of fan main body interlayer dividing plate 18 makes the multiplication of complete blower capacity.Also can be installed in blower fan on the semi-submersible type buoyancy tank and be fixed on the sea by anchor chain.Or directly with the fixed installation of pile structure at sea.To set up marine wind field.Utilize fan main body wind deflector 22 to increase the reverse windage of cut-off wind area and the minimizing fan blade 16 of blower fan.Wind deflector 22 is exactly that a kind of arc plate with certain garden arcuate surface can be with the less windage direction that guiding need wind of keeping watch.The effect of the peripheral wind deflector 22 of blower fan, wind deflector 22 increases the cut-off wind area of blower fan when fan blade 16 forwards facing the wind.Fan blade reverse facing the wind to the time, wind deflector 22 has blocked the counter blow that blows to fan blade 16, plays the effect of barge board, and a part of counter blow led changes into just aweather.When reducing the reverse windage of fan blade 16, increased the forward wind-force of fan blade 16.The wind gathering cover 14(of the toroidal that a circle is connected to form by arc plate is arranged with reference to Fig. 1, Fig. 3, Fig. 5 in blower fan external rotor 20 and cantilever structure 15 in addition), wind can not be left from fan blade 16 two, play the effect of wind gathering.Thereby can reduce the incision wind speed of blower fan.Mechanical strength and the blower fan external rotor 20 integrally-built stability of blower fan external rotor 20 and cantilever structure 15 have also been increased simultaneously.Brake system 9 is arranged between the wind gathering cover 14 and structural connection 2 at external rotor 20 two ends; But the interlayer on the vertical axial wall 1 of hollow is installation and repairing mouth 21 or hollow vertical axle 23 also, and its inner space can install elevator, cat ladder Ge winding stair etc. additional so that usefulness such as installation and maintenance.As shown in Figure 1 and Figure 2, shown in the structure of installation and repairing mouth 21, hollow vertical axle 23, use in the time of can being used for handling, installation, maintenance, repair apparatus.
