DUAL-DUCT AXIAL FLOW TYPE WIND POWER GENERATION SYSTEM

摘要

A dual-duct axial flow type wind power generation system includes a front pipeline (1) and a rear pipeline (2) arranged in a front-and-rear sleeved manner. The rear pipeline (2) is sleeved outside of the front pipeline (1). The front pipeline (1) and the rear pipeline (2) are fixedly supported by a supporting plate (6) therebetween. The fore pipeline (1) is provided with the first condensation pipe (11) and the first wake pipe (12), the rear pipeline (2) is provided with the second condensation pipe (21) and the second wake pipe (22). An axial distance is formed between air inlets of the first and the second condensation pipes (11, 12), and the first condensation pipe (11) is in the front of the second condensation pipe (21). The first wake pipe (12) is arranged close to the tail end of the second condensation pipe (21). Through holes (3) are arranged along the periphery of the tail end of the first wake pipe (12). An impeller (4) is arranged on the tail end of the first condensation pipe I (11). A guide blade (5) close to the impeller (4) is arranged inside of the front pipeline (1). The impeller (4) is driven to rotate by wind power, and thus to drive a generator (30) to generate electricity. The wind power generation system can increase wind speed in the pipes, so that the wind energy utilization rate and the efficiency of the generator are further improved.
