Abstract

The invention discloses a wind turbine blade with an embedded diversion pipe capable of controlling tip vortex. The wind turbine blade comprises a blade tip device, an air inlet, an air outlet and a diversion pipe, wherein a plurality of air inlets are arranged at the leading edge nearby the blade tip of the blade tip device; a plurality of air outlets are arranged at the blade tip of the blade tip device; the air inlets are communicated with the air outlets by diversion pipes; and the diversion pipes are internally provided with throttling devices for controlling the air flow. The wind turbine blade provided by the invention has simple structure, is used as a blade extension segment connected to the wind turbine blade without changing the main body of the wind turbine blade, and is separately designed according to the actual situation of providing the blade wind turbine, or integrally designed by considering the device and the pneumatic structure portion of the wind turbine blade as a whole, thus maximally controlling the generation of the tip vortex, improving the pneumatic efficiency of the wind turbine and reducing the noise level.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a wind turbine blade with an embedded draft tube for controlling blade tip vortex. technical background [0002] A wind turbine is a mechanical device that converts wind energy into electrical energy. The aerodynamic design level of the blades directly affects the wind-capturing capacity of the wind turbine rotor, the selection of other components except the blades, the implementation level of the control strategy, and the reliability of the whole machine. is the cost of generating electricity from the wind turbine. With the current wide application of wind turbines, wind farms are inevitably installed near residential areas, and the noise of wind turbines during operation has become an unavoidable issue that needs to be considered in the design of wind turbines. In order to further improve the wind energy utilization rate of the wind turbine, the tip spe...
