<p>An airflow collection device includes an airflow collection channel (1, 101) provided with a large outer port and a small inner port. A flow-guiding body (2, 102) is arranged in the airflow collection channel (1, 101). A wind motor includes the above-mentioned airflow collection device, at least one impeller chamber (104, 106), and at least one impeller (113, 110) mounted in the impeller chamber (104, 106) via a power output shaft (109). Blades (105, 111) are fixed on the radial outer peripheral surface of the impellers (113, 110). An airflow channel (103) formed between the flow-guiding body (102) and the airflow collection channel (101) is communicated with blades (105, 111), so that the airflow collected in the airflow channel (103) directly acts on the blades (105, 111). The device can further optimize airflow collection, centralize the collected airflow in a better manner and enable the wind motor to utilize the collected airflow more efficiently so as to produce greater power.</p> |
