Benefits of technology

This patented technology helps protect generators from damage caused due to strong gusts or high speeds during operation. It achieves this through reducing airflow over certain parts of the machine while it faces stronger ones with lower safety limits.

Problems solved by technology

This patented technical problem addressed in this patents relates to preventing damage caused during over-wind conditions that could cause failure of the main components such as the gearboxes used for transmitting torque between them and other parts like bearings supporting the hubs carrying generators.

Embodiment Construction

[0015] For ease of explanation, the main idea expressed in the column of the above-mentioned content of the invention of this case is expressed with specific embodiments. Various objects in the embodiments are drawn according to proportions, sizes, deformations or displacements suitable for illustration, rather than drawn according to the proportions of actual components, and are described first. And in the following description, similar components are denoted by the same numerals.

[0016] Such as Figure 1 to Figure 3 , describing a wind generator with the wind shelter of this case. The wind power generator includes a tower 10 , a nacelle 11 is assembled at the top of the tower 10 , and a fan 12 is arranged at the front end of the nacelle 11 . The power generating mechanism inside the nacelle 11, the braking system, and the connection relationship between the aforementioned two and the fan 12 are known technologies, which are not the key points of the present case, and will n

Abstract

The invention relates to windshield speed-reducing device and method of a wind power generator. When a wind power generator encounters wind power which is larger than safe wind speed, a fan and a cabin are steered by the start of a windshield device so that the rotating plane of the fan is parallel to the direction of wind. The wind power generator comprises a pylon; a cabinet is assembled on the top end of the pylon; and the front end of the cabinet (11) is provided with a fan. The windshield device comprises an aerovane, a processor and a steering controller, wherein the aerovane is installed on the wind power generator and generates a wind direction and wind speed signal; the processor is installed on the wind power generator and coupled with the aerovane, receives the wind direction and wind speed signal, calculates a deflecting angle of the cabinet of the wind power generator according to the wind direction and wind speed signal and converts the deflecting angle into a deflecting angle signal; and the steering controller is installed on the wind power generator, used for controlling the deflection of the cabinet and coupled with the processor, receives the deflecting angle signal and controls the cabinet to deflect in a preset angle.
