Problems solved by technology
The structure used to connect the two hubs and the blades is relatively thin, and the weight of the blades it can bear and the height of the equipment are limited. At present, the support arms connecting the hubs and supporting the blades on most vertical axis wind power generation equipment are single pipe, single plate or double Pipe fittings and double-plate parts, the diameter of the wind rotor that this connection method can bear is limited, and the input torque and motor power cannot be increased. The transmission shaft between the two hubs is relatively short. At the same time, the power generation equipment that this method can carry The height is also limited, the swept area of the fan cannot be increased, and the power generation of the power generation equipment is low

Embodiment Construction
[0015] The blade support arm on a vertical axis wind power generation device of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0016] figure 1 It is a structural schematic diagram of a blade support arm on a vertical axis wind power generation device of the present invention, figure 2 yes figure 1 Partial enlarged view at A in the middle, image 3 yes figure 1 top view. In the figure, the blade support arm 2 on the vertical axis wind power generation equipment includes a plurality of tubular support beams, circular nodes and hub flanges, and the circular nodes are set as upper, middle and lower layers of circular nodes 8, 9, 10, the number of circular nodes in each layer is set to 5, and they are evenly distributed on a horizontal concentric circle. On the blue plates 11 and 7, the blade support arms 2 of each layer are connected through the transmission shaft 1, and the circular nodes 10, 9...

The invention discloses a blade supporting arm on vertical axis wind power generation equipment. The blade supporting arm comprises a plurality of supporting beams, round joints and a hub flange plate. The round joints are arranged on an upper layer, a middle layer and a lower layer, five round joints are arranged on each layer and are evenly distributed on one horizontal concentric circle, and the round joints are connected through the supporting beams. The round joints on the upper layer and the lower layer extend outwards through the supporting beams, and the top ends of the supporting beams on the upper layer and the lower layer are connected with fixed blades. According to the supporting arm, the rotary diameter and height of the vertical axis wind power generation equipment can be increased, stable supporting between a hub and the blades can be guaranteed, the input power and annual power output are improved, and the input power of the power generation equipment reaches the megawatt level.
Description
technical field [0001] The invention relates to the field of power generation equipment, in particular to a blade support arm on vertical axis wind power generation equipment. Background technique [0002] Most of the existing vertical axis wind power generation equipments have a diameter of less than 20 meters and a height of less than 5 meters. The structure used to connect the two hubs and the blades is relatively thin, and the weight of the blades it can bear and the height of the equipment are limited. At present, the support arms connecting the hubs and supporting the blades on most vertical axis wind power generation equipment are single pipe, single plate or double Pipe fittings and double-plate parts, the diameter of the wind rotor that this connection method can bear is limited, and the input torque and motor power cannot be increased. The transmission shaft between the two hubs is relatively short. At the same time, the power generation equipment that this method ...
