SUMMERY OF THE UTILITY MODEL
The utility model provides a connecting rod for connecting vertical axis wind energy conversion system blade and main shaft to resistance that the connecting rod receives when solving wind energy conversion system and being great and lead to starting the difficult problem.
The utility model adopts the following technical scheme: a connecting rod for connecting vertical axis wind turbine blade and main shaft which characterized in that: comprises a framework, a supporting plate and an elastic shell. The framework is a rectangular column extending along the front-back direction. The stay plate includes a rectangular portion and a semicircular portion. The rectangular part sideline and the semicircle part chord line coincide and are connected. The middle part of the rectangular part of the supporting plate is provided with a rectangular hole for the supporting plate to be sleeved on the framework. The supporting plates are arranged in a plurality and are distributed on the peripheral wall of the outer side of the framework along the front-back direction. The elastic shell is sleeved outside the supporting plate to form a curved surface of the connecting rod at the semicircular part of the supporting plate, the curved surface is a windward surface to reduce windage resistance by generating concave deformation after receiving windage resistance, and the vertical surface of the connecting rod formed at the rectangular part provides corresponding starting force for the wind turbine by thrust received by wind.
Furthermore, mounting plates are arranged at two ends of the connecting rod.
Further, the skeleton is arranged in a hollow mode.
The beneficial effects of the utility model are that: when the wind turbine is started, the vertical surface side of the connecting shaft is subjected to wind resistance to reversely push the wind turbine so as to provide corresponding driving force, the curved surface side serves as a windward surface to reduce the rotation resistance of the wind turbine, meanwhile, the elastic shell on the connecting rod supporting plate enables the curved surface of the connecting rod to be subjected to concave deformation after the wind resistance, the resistance area is reduced so as to reduce the wind resistance, the larger the wind resistance of the curved surface is, the larger the concave deformation degree is, the thrust force received by the vertical surface is greater than the resistance force received by the curved surface, so that the starting of the wind turbine is promoted, and the starting of the wind turbine is promoted.
Furthermore, when the blades rotate stably, the elastic shell resets outwards, so that corresponding lifting force is provided for the rotation of the wind turbine, and the utilization rate of the wind turbine on wind energy is improved.
