Abstract

A full-load brake-wheel-free type wind power generation device comprises a spoke type fan impeller, a spoke, blades, a horizontal hub, a horizontal shaft, a spoke type fan impeller outer rim, an outer rim protection cover, a spoke type fan impeller support, generators, a base rotary disc, deviation correction motors, a wind indicator, a base, a hydraulic adjusting device, an arc-shaped generator mounting support and a control system. The spoke type fan impeller is arranged on the horizontal shaft of the spoke type fan impeller support through the horizontal hub. The spoke type fan impeller support and the arc-shaped generator mounting support are fixedly arranged on the base rotary disc. The base rotary disc is movably arranged on a round guide rail of the base. The angle of the base rotary disc is adjusted through the deviation correction motors on the base according to pointing of the wind indicator, and the blade windward side of the spoke type fan impeller is made to exactly face the wind direction. More than two generator sets are in elastic and close contact with the spoke type fan impeller. The control system determines the number of the generator sets put into work according to wind power, and full-load wind power generation is achieved.

Description

technical field [0001] The invention relates to the field of wind power generation, and specifically relates to a full-load non-braking wheel type wind power generation device, which is especially suitable for various large-scale wind power generation sites. Background technique [0002] At present, the devices widely used for wind power generation are mainly horizontal-axis wind generators, and most horizontal-axis wind generators adopt the mode of installing three blades on the hub. Due to the small number of blades installed in such a design mode, the wind-receiving area of ​​the impeller as a whole is small, the power generation is small, and the efficiency of the whole machine is low. There are also vertical axis wind turbines. Due to the poor aerodynamic performance of the blades, the efficiency of the whole machine is not high. In addition, in order to consider the safety performance of the whole wind turbine under strong wind, almost all wind generators have brake ...
