Wind collecting and protecting system of aerogenerator

Abstract

The invention relates to a wind collecting and protecting system of an aerogenerator, belonging to the technical field of wind power generation. The wind collecting and protecting system comprises a wind collecting plate driving system, a drive traction system, a wind collecting plate system and a framework part; wherein, the wind collecting plate driving system comprises a lower driving bracket,an upper driving bracket, a lower connecting support and an upper connecting support of the wind collecting plate, a driving support shaft, a speed reducer and an electric motor; the drive traction system includes a drive sprocket, a traction chain and a driving wheel; the wind collecting plate system comprises a wind collecting plate, a lower sheave of the wind collecting plate, a top sheave of the wind collecting plate, a lower slideway and an upper slideway; and the framework part comprises a lower framework, an upper framework and a vertical framework. The angle between the wind collecting plate and the framework of the aerogenerator is within the range of 0-45 degrees, and is driven, regulated and controlled by the electric motor and a speed changer, so that the wind collecting plateis driven and pulled to slide on the slideways, thus adjusting and changing the size of a wind inlet and the wind collecting quantity of the wind collecting plate; when the wind speed is too high or storm wind, the wind collecting plate and the wind inlet are closed to play the role of protecting the system.

Description

technical field [0001] The invention relates to a system in the technical field of wind power generation, in particular to a wind collection and protection system for a wind power generator. Background technique [0002] With the development of the world's energy crisis, the use of wind kinetic energy as a new energy source for the development of modern society has become a hot spot in social development. Traditional wind turbines do not have wind collection and protection systems, so the utilization rate of wind power is low, and wind turbines are large in size and easily damaged by storms. After adding the wind collection and protection system, the wind power utilization efficiency and air collection volume of the wind turbine are increased. Under the same capacity, the volume of the wind turbine is reduced, which is convenient for the large capacity of the wind turbine. After adding the wind collection and protection system to the wind turbine, the wind collection and pr...

Problems solved by technology

The structure of this model adopts the reinforced concrete wind collecting wall, which is bulky and has low flexibility and cannot adapt to changes in wind direction.

[0005] It was also found in the search that Chinese Patent Publication No. CN201144765 provides a wind-gathering wind generator. This technology has a plurality of movable wind-collecting wind hoods, and each wind-gathering wind hood is equipped with a rudder and the multiple wind hoods pass through a flexible conduit. Connected to an air collecting tube, this method can only be used for a small-capacity generator, and is limited by the structure of multiple movable air collecting wind hoods and the driving capacity of the rudder
