The front part of the commutation shell is a baffle, and the rear part of the commutation shell is a wind direction rudder. The commutation shell is provided with a rotary vertical shaft through a bearing. The vertical shaft windmill is composed of an upper plate, a lower plate and swing blades, and is fixed with the rotary vertical shaft. The top of the vertical shaft is provided with a stable panel through a bearing, and the panel is provided with a plurality of traction ropes. The lower part of the rotary vertical shaft is provided with an overspeed governor and a socket, and an electric generator is arranged in the socket. The rotary shaft vertical is provided with a socket through a bearing, and is connected with the electric generator through a shaft coupling.
Description
The utility model relates to a kind of high-efficiency wind driven generator, and this generator adopts the vertical shaft windmill, can utilize the wind-force of all directions expeditiously.
Wind-driven generator commonly used mostly drives generator for electricity generation by the wind wheel of horizontal axis, the efficient of this wind wheel is lower, therefore, Chinese patent CN88216128.8 discloses a kind of vertical-shaft aerogenerator, this machine has upper plate, the wind-gathering device that lower plate and wind deflector constitute, be provided with a plurality of wind scoops in the center portion around vertical shaft, by wind gathering concentrated blow in wind scoop of wind-gathering device with the windward side, make vertical shaft drive generator for electricity generation, no matter how wind direction changes, can both wind be concentrated by the collection of wind deflector and quicken to blow the vertical shaft rotation, can improve the efficient of wind-power electricity generation, but the volume of the wind deflector device of this patent is bigger, its windward side is also bigger, to having relatively high expectations of basis, invest bigger, in addition, except the wind deflector with the airflow direction unanimity has preferably wind effect, the efficient of remaining wind deflector wind-guiding is relatively poor, and total efficient is still not ideal.
The purpose of this utility model provides a kind of high-efficiency wind driven generator, and this wind-driven generator has rational windward side, can effectively utilize the wind-power electricity generation of all directions.
The purpose of this utility model is realized by following technical proposals: a kind of high-efficiency wind driven generator, a vertical shaft windmill is arranged, be provided with the rectification housing in the outside of described windmill, the front portion of this rectification housing is a deflector, its rear portion is the wind direction rudder, its middle part one side is provided with intake grill, opposite side is provided with enclosing housing, this rectification housing is installed by bearing and vertical rotation shaft, described vertical shaft windmill is by upper plate, lower plate and swing type blade constitute, this vertical shaft windmill and vertical rotation shaft are fixed, and firmly coil by one of Bearing Installation at the top of described vertical shaft, and this dish is provided with many drawing ropes, the bottom of described vertical rotation shaft is provided with speed limiting device and base, generator is housed in the base, and described vertical rotation shaft is installed by bearing and base, is connected with generator by coupling.
The utility model is compared with technology is arranged, and it is reasonable to have a wind-exposuring area, and frontal resistance is little, the advantage high to wind power utilization efficient.
The utility model is described in further detail below in conjunction with drawings and Examples.
