Centrifugal speed-regulating tail-folding yaw type wind power generator

Abstract

The invention discloses a centrifugal speed-regulating tail-folding yaw type wind power generator which comprises a blade (1), a tail vane (2), a tail vane fixing frame (3), a tail vane rotary shaft (4) and a transmission shaft (5). The tail vane (2) is disposed on the tail vane rotary shaft (4). A bearing and a bearing block are mounted at two ends of the tail vane rotary shaft (4) which is mounted on the tail vane fixing frame (3). The blade (1) is mounted on the transmission shaft (5). The wind power generator further comprises a centrifuge (6) and a ball head ball seat connecting rod (7). One end of the ball head ball seat connecting rod (7) is connected with the transmission shaft (5). The other end of the ball head ball seat connecting rod (7) is connected with the tail vane rotary shaft (4). The centrifuge (6) is disposed on the transmission shaft (5). A spring (8) is sleeved on one end, close to the centrifuge, of the ball head ball seat connecting rod (7). The wind power generator is safe, effective and optimal in power generating efficiency, power generation in heavy winds can be achieved, and generator damage caused by heavy winds can be avoided.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a centrifugal speed-regulating folding tail yaw type wind power generator. Background technique [0002] Wind energy is a good renewable and non-polluting resource, especially in the southeast coast of my country where there is a large amount of marine wind energy. Wind power generation is the main form of wind energy utilization, and wind generators are necessary devices for converting wind energy into electrical energy. The wind generators in the prior art generally include a wind wheel, a transmission mechanism, a generator, a yaw mechanism and control components, etc. The yaw mechanism is also called a wind-facing mechanism, and its function is to quickly and stably Align the wind direction so that the wind rotor can get as much wind energy as possible. [0003] However, due to the lack of controllable and effective wind-shielding devices in the current miniature wind-d...

AI Technical Summary

Problems solved by technology

[0003] However, due to the lack of controllable and effective wind-shielding devices in the current miniature wind turbine structure, the speed of the wind turbine rotor is directly proportional to the wind speed.

Exceeding the rated wind speed, the speed of the wind rotor of the generator will increase exponentially. Once the wind force of level 10 or above occurs, the wind turbine will be damaged to varying degrees due to the excessive speed of the wind rotor, and the loss will be great.

[0004] Especially when using offshore wind energy to generate electricity, the ocean wind conditions are complicated, and winds of grade 10 are common. Ocean-going ships are still operating when winds of grade 9 are used, and wind shelters are used only when winds of grade 10 are above. , it is easy to damage the wind turbine
