fixed mounting has second L shape backup pad (35) on horizontal axis (26), second worm (36) are installed to second L shape backup pad (35) internal rotation, second L shape backup pad (35) are run through and driving gear (37) are installed to the upper end of second worm (36), driving gear (37) are connected with gear seat (34) meshing.
10. A wind detection method of a wind power generator, which adopts a wind detection system of a wind power generator according to any one of claims 1 to 9, characterized by comprising the following operation steps:
step 1: before detection, symmetrically arranged U-shaped seats (3) are arranged on a support frame (2) through bolts;
step 2: during detection, the fan blades (9) are blown by wind power to rotate, the fan blades (9) drive the chronic shaft (5) to rotate, and the first conical teeth (24) positioned on the chronic shaft (5) drive the second conical teeth (30) in meshed connection to rotate so that the encoder detects the rotating speed of the fan blades (9);
and step 3: when the wind speed changes, the driving motor (32) approaches to the first worm (28), the worm wheel (33) is meshed with the first worm (28) for transmission, the pitch between the fan blades (9) is changed through the adjusting piece, the encoder detects the rotating speed of the fan blades (9) again, and the rotating speed of the fan blades (9) is kept stable;
and 4, step 4: the driving motor (32) approaches to the second worm (36), the worm wheel (33) and the second worm (36) are in meshed transmission, the windward angle between the fan blade (9) and the wind direction is changed, the encoder detects the rotating speed of the fan blade (9) again, and the rotating speed of the fan blade (9) is optimized.
