Problems solved by technology

However, setting up the hot air cavity will easily affect the overall performance of the wind turbine blades. At the same time, the hot air cavity is only installed in the parts that may freeze, and sometimes freezes in other parts, so the deicing effect is not very good.
The heating wire installed on the wind turbine blades is not only easy to damage, but also makes the weight distribution of the blades uneven, so that the deicing effect is not very ideal
Although the cost of shaking deicing is low, the effect is also the worst among several methods.

Abstract

The invention relates to a horizontal axis wind generating set with a de-icing device. The horizontal axis wind generating set with the de-icing device comprises a wind generating component, a de-icing external support component, a rainwater treatment chamber, a steam treatment component and a hot air component. Through specifically arranging the various components, after the surface of a wind turbine blade is found to be frozen, namely, after a cabin position is fixed through a cabin card component, a heat-insulating component is raised and a wind power blade is blown by the hot air, so the effect of removing the ice on the blade surface effectively is realized.

Description

technical field [0001] The invention belongs to the fields of wind power generation and intelligent environmental protection, and in particular relates to a horizontal axis wind power generating set with a deicing device. Background technique [0002] Due to the high position of the wind turbine blades of the wind turbine, and the wind turbines are generally installed in the alpine and windy regions of the northwest, the wind turbine blades are very easy to freeze, and the ice on the blades will bring great harm to the overall operation of the wind turbine. Big hidden danger. At present, there are several ways of deicing wind power blades, some are equipped with hot air chambers inside the blades, some are equipped with heating wires outside the blades, and some are deiced by adjusting the rotation frequency of wind power blades to make them vibrate. However, the installation of the hot air chamber will easily affect the overall performance of the wind turbine blades. At th...
