It is not connected on upper and lower wheelboss flange disk, is connected with each other between upper, middle and lower-ranking circular node further through supporting beam, middle layer
5 circular nodes are mutually shifted to install with upper and lower two layers of circular node along horizontal circle week, in upper and lower two layers of circular node
Extended outwardly by supporting beam, supporting beam be set in the circular node in middle layer and is respectively supported in upper and lower two layers of supporting beam,
Upper and lower two layers of supporting beam top is connected and fixed air blade.
In above scheme, the circular node is hollow steel sphere, is provided with multiple seats connecting with supporting beam on sphere
Hole is marked, sphere is with supporting beam by being welded and fixed.
In above scheme, the circular node is solid bolt sphere, is provided on sphere and multiple connect with supporting beam
Bolt hole, sphere and supporting beam are connected through a screw thread fixation.
In above scheme, the supporting beam is hollow tubular profile.
Blade supporting arm on a kind of vertical axis wind-mill generator of the present invention compared with prior art, its advantages
It is:
1. the support arm of the invention uses truss structure, the crushing resistance of steel ball, the stability of triangle and pipe fitting are utilized
Flexing resistance, bigger rotor diameter can be born, the input torque and power of motor of generating equipment is improved, realize high-power
Wind-power electricity generation.
2. the invention increases the rotating diameter and height of vertical axis wind-mill generator, ensure that between wheel hub and blade
Firm support, improve input power and annual electricity generating capacity.
