Description

technical field [0001] The invention relates to the technical field of generators, in particular to a multi-pitch wind power generator. Background technique [0002] During the process of generating electricity, the wind speed will determine the speed of the blade rotation. If the blade rotates too fast, the wind will have a strong impact on the blade, which will seriously damage the blade. Therefore, when the wind is strong , the angle of attack of the blade needs to be reduced; when the wind force is small, the angle of attack of the blade needs to be increased. According to the search data of the research team, it is found that a pitch variable mechanism can effectively solve this problem. It can adjust the pitch angle at any time according to the change of wind speed and control the captured mechanical energy. On the one hand, it can ensure the maximum wind energy and reduce the impact of wind on the blades. Impact, which adopts the variable pitch control system and the...

According to the search data of the research team, it is found that a pitch variable mechanism can effectively solve this problem. It can adjust the pitch angle at any time according to the change of wind speed and control the captured mechanical energy. On the one hand, it can ensure the maximum wind energy and reduce the impact of wind on the blades. Impact, which adopts the variable pitch control system and the variable speed constant frequency technology, the structure is relatively complex, the cost is high, and it brings a lot of inconvenience to the maintenance of the management personnel. Moreover, the current wind turbines can only capture wind energy. Neither sunny nor windy weather nor rainy and windless weather can capture wind energy for power generation, which restricts the continuous operation of wind turbines and reduces the power generation efficiency of wind turbines. Based on this, design a multi-pitch natural energy generator with ingenious structure, simple principle, automatic pitch change and the ability to capture and utilize solar energy and rainwater potential energy
