Wind-driven generator synchronous belt transmission automatic wind-aiming drift device

Abstract

The invention is a timing belt transmission automatic wind opposing deviation device of a wind power generator. A power generator (15) is connected with a revolving body (engine cabin) (18). The revolving body shaft (17) is connected with a pole (16). The shaft (17) is provided with a carbon brush (2), a carbon brush (3) and a large synchronous belt pulley (4). The shaft (17) cooperates with the engine cabin (8) via a cone gear (14) and a deep groove ball bearing (19). The engine cabin (18) is equipped with a timing belt tension spring (20) outside, which is connected with a stepped electric motor (11). The stepped electric motor (11) is connected with a small synchronous belt pulley (6). Thus, the revolving body can drive the small synchronous belt pulley (6) to rotate circumferentially around the large synchronous belt pulley (4) on the revolving body shaft (17) via a timing belt (5). The carbon brush (2) is responsible to input the externally stored electric current into the stepped electric motor (11), while the carbon brush (3) is responsible to output the power generated by the generator (15). The advantage of the wind deviation device is that when the wind power generator is working, the device can oppose the wind automatically and deviates from the wind in the case of a strong wind, so as to reach the purpose of automatic speed controlling and limiting and achieve the self-protection function of the wind power generator. The device avoids large tail fins of a wind power generator in the past. With the device, a wind power generator can be controlled and operated intelligently, is more reliable in the work, and is free of maintenance for a long time.

Description

technical field [0001] The invention relates to the field of wind power generation and mechanical transmission. Background technique [0002] When the wind turbine is working, it is necessary to realize the automatic wind facing of the wind turbine and the automatic yaw when encountering strong wind to achieve the purpose of automatic speed regulation and speed limit, so as to play the role of wind turbine self-protection and automatic wind facing. And the wind-driven generator in the past adopts huge empennage, is all unsuitable to use in the large and medium-sized wind-driven generator. Some wind turbines without tail fins are driven by conventional gearboxes. In large-scale grid-connected wind turbines, gearboxes are used, so regular maintenance by professionals is required. However, small and medium-sized wind turbines cannot be maintained manually due to their small size, which increases the difficulty of long-term self-protection capabilities of wind turbines.

Problems solved by technology

In the past, wind power generators used huge tail fins, which were not suitable for use in large and medium-sized wind power generators.

Some wind turbines without tail fins are driven by conventional gearboxes. In large-scale grid-connected wind turbines, gearboxes are used, so regular maintenance by professionals is required.

However, small and medium-sized wind turbines cannot be maintained manually due to their small size, which increases the difficulty of long-term self-protection capabilities of wind turbines.
