Abstract
An external-rotor vertical shaft aero generator comprises an upper end cover, a lower end cover, an outer rotor, an inner stator, a bearing and a wind wheel, wherein, the upper end cover is totally sealed, the outside diameter of the upper end cover is larger than that of the outer rotor, a fan blade of the wind wheel is arranged on the periphery of the outer rotor, and the radius of turn of the fan blade is larger than that of the outer rotor. Therefore, the wind wheel has a large swept area and great transferred torque. With high wind power utilization rate, good barrier property, a simple structure and convenient installation, the utility model has greater practicability.
Description
Technical field
The utility model relates to a kind of motor, is a kind of external rotor type vertical axis aerogenerator specifically.
Background technique
Wind-driven generator has two kinds at present, and a kind of is horizontal axis wind-driven generator, and another kind is a vertical wind power generator, the former structure comparative maturity, and the latter is then mostly for the development stage.The master of existing vertical axis aerogenerator is not high if it were not for wind energy utilization, and rainproof snow defence leakage proof is undesirable, and complex structure inconvenience is installed, so practicability is relatively poor.
The model utility content
The purpose of this utility model is to provide a kind of and can improves wind energy utilization.Barrier propterty is good, the motor internal infiltration of can not intaking, external rotor type vertical axis aerogenerator simple in structure, easy for installation.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of external rotor type vertical axis aerogenerator, comprise upper end cap, lower end cap, external rotor, inner stator, bearing and wind wheel, it is characterized in that: upper end cap is totally enclosed, its external diameter is greater than the external diameter of external rotor, the fan blade of wind wheel is installed in the periphery of external rotor, and its turning radius is greater than the radius of external rotor.
The fan blade of described wind wheel is directly installed on a week of upper end cap outer rim.
Described generator is adorned the wind wheel seat in addition in the external rotor outside, and fan blade is contained on the wind wheel seat.
The double-screw bolt that described generator utilizes inner stator axle bottom to stretch out is installed.
The removable flange plate of described generator utilization dress jail on the double-screw bolt of bottom installed.
Adopt the utility model product of said structure, it is simple in structure, and is easy for installation, the wind energy utilization height, and protective is good, has tangible advantage.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and application example.
Fig. 1 is a structure diagram of the present utility model, and 1-1 is a bearing among the figure, and 1-2 is a upper end cap, 1-3 is upper end cap rigging screw, 1-4 is an external rotor, and 1-5 is an inner stator, and 1-6 is that rigging screw is given in the lower end, 1-7 is a lower end cap, 1-8 is that hexagon helps piece, 1-9 for install use seal ring, 1-10 be the inner stator hollow shaft silently, 1-11 hits thread casing for drawing, and 1-12 hits line for wear drawing of hitting from the inner stator hollow shaft.
As shown in Figure 1, the external rotor type vertical axis aerogenerator, comprise upper end cap 1-2, lower end cap 1-7, external rotor 1-4, inner stator 1-5, bearing 1-1, the upper end cap 1-3 of generator is totally enclosed, above without any the hole, hole or slot, and also its external diameter is greater than external rotor 1-4 external diameter, so the tool area coverage has surpassed the sectional area of generator fuselage, therefore rain, snow, hail and dirt sand there is good protective action.
Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7 are several mounting types of fan blade of wind wheel and the schematic representation of mounting point.Wherein fan blade is installed in week of upper end cap 1-2 outer rim among Fig. 2 to Fig. 6, and its turning radius is greater than the radius of external rotor.Open type on Fig. 2, fan blade 2-1 opens outward; Fig. 3 is a droop, fan blade 3-1 lifting; Fig. 4 is a droop, reinforces below the fan blade 4-1; Fig. 5 and Fig. 6 are the structural representations of double-deck fan blade.
The cylindrical of end cap 7-1 is littler than the end cap 1-2 among Fig. 1 among Fig. 7, has adorned windward wheel seat 7-2 and leeward wheel seat 7-4 in addition in generator external rotor outside, and fan blade 7-3 is contained on the wind wheel seat.This mounting type has increased the turning radius of fan blade, and the torque that wind wheel passes to the generator external rotor is bigger.
The common feature of Fig. 2 to Fig. 7 is the external diameter of the external diameter of upper end cap greater than external rotor, the fan blade of wind wheel is installed in the periphery of external rotor, its turning radius was greater than the external rotor radius when therefore fan blade rotated, the surface sweeping that has increased wind wheel is long-pending, increase wind-force and passed to the torque of generator, improved utilization ratio of wind energy.
Mounting type of the present utility model has two kinds, and a kind of is the double-screw bolt that utilizes inner stator axle bottom to stretch out; Another kind is to utilize the removable flange plate that is contained on the above-mentioned double-screw bolt.Fig. 8 is the structural representation of flange plate dress, and circular flange dish 8-1 has been adorned in the generator bottom among Fig. 8, adds to help piece 1-8 and nut 8-2 to tighten up and down on the double-screw bolt of Fig. 1 again.
Fig. 9 is one of application example of the present utility model, and external rotor type vertical axis aerogenerator 9-1 is installed on the electric pole 9-2 of street lamp among Fig. 9, and the double-screw bolt of generator bottom directly advances in the screw of electric pole upper end.
Of the present utility model simple in structure, easy for installation, the wind energy utilization height, protective is good, Has obvious advantage.
