Problems solved by technology

[0005] At present, the anti-wind and sand technology adopted in the field of wind turbines is generally passive. Considering the ventilation performance of the filter and the aging of the sealing components, it cannot meet the long-term anti-wind and sand requirements.
The introduction of a complex filter ventilation system involves power and energy consumption issues

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] like figure 1 As shown, the self-adaptive anti-wind and sand device for the wind power generating set includes the cabin body of the wind power generating set and the filter pressurization transmission device in the cabin. The cabin body of the wind generating set is divided into three sections, followed by the bowl-shaped head 29, A cylindrical body 5 open at both ends and a tail 12 with a rounded convex surface. The head 29, the body 5 and the tail 12 are sequentially spliced ​​to form the cabin body of the wind power generating set, and the body outside the cabin is provided with a yaw bearing 25, which is used to connect with the tower of the wind power generator. Windows 10 is open.

[0022] The filter booster transmission device includes a plurality of pulleys, a first bevel gear reversing mechanism, a second bevel gear reversing mechanism, a screw compressor...

Abstract

The invention relates to an adaptive wind and sand prevention device for a wind generating set. The conventional equipment has poor wind and sand prevention capacity and a complex structure. In the device, an air filtering device consisting of a filtering net and a filter is adopted to filter external air in wind and sand environment; the filtered air is pressed into a cabin by a screw compressor; the rotation of a main shaft of a blower is transferred to the filter and the compressor through a belt pulley and gear transmission system in rational proportion, so that the filtering and boosting can be realized without additional power system; and the air pressed into the cabin ensures that the air pressure in the cabin is higher than the external atmospheric pressure, so that the wind and the sand cannot enter the cabin from a revolving pair or installation clearance of the cabin so as to realize a wind and sand prevention function.

Description

technical field [0001] The invention belongs to the technical field of electric power protection equipment, and relates to an adaptive wind and sand prevention device for a wind power generating set. Background technique [0002] Wind power generation is an important development direction of clean energy technology. At present, wind power generation is developing towards large scale. my country's land-based wind farms are mainly concentrated in areas rich in wind energy resources such as Northeast China, Inner Mongolia and Xinjiang. However, these areas have more wind and sand, and the sky is filled with wind and sand, and the wind field is often accompanied by wind and dust. The impact of wind and sand on wind turbines mainly includes damage to rotating transmission systems such as bearings, gears, and rotating shafts, and damage to generators and their control systems. The infringement of sand and dust on the rotating transmission chain will cause vibration, jamming, fa...
