AI Technical Summary

Problems solved by technology

The device judges whether it is icing by detecting the temperature of the blade surface. This method cannot completely judge whether the fan blades are icing under low temperature conditions in areas with less water in the air, and it also uses heating to deicing, which consumes energy. Big

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] The core of the present invention is to provide a blade anti-icing and de-icing system for wind power generators, which can accurately detect and judge the icing situation of the blades, and can automatically de-ice in time, and finally de-icing by itself under the condition of energy saving processing, with high reliability in detecting de-icing and anti-icing. In order to make those skilled in the art better understand the technical solution of the present invention, the following in conjunction with the attached figure 1 And attached figure 2 And the specific implementation method will further describe the present invention in detail.

[0024] like figure 1 As shown, the fan blade automatic anti-icing and deicing system of the present invention includes an icing analysis unit 1, a standing wave deicing unit 2, a traveling wave anti-icing unit 3,...

Abstract

The invention discloses an automatic anti-icing deicing system and an anti-icing deicing method for a fan blade. The automatic anti-icing deicing system for the fan blade comprises an icing analytic unit, a standing wave deicing unit, a traveling wave anti-icing unit, a vibration frequency sensing unit and a control unit, wherein the icing analytic unit, the standing wave deicing unit, the traveling wave anti-icing unit and the vibration frequency sensing unit are arranged in the fan blade, and the icing analytic unit, the standing wave deicing unit, the traveling wave anti-icing unit and the vibration frequency sensing unit are respectively connected with the control unit. The automatic anti-icing deicing system and the anti-icing deicing method for the fan blade have the advantages that icing condition of the fan blade can be rapidly and accurately determined; further ice blocks on the fan blade can be timely and automatically removed; and anti-icing treatment can be automatically carried out, so that serious icing on the fan blade is prevented, and normal operation of a fan is guaranteed.

Description

technical field [0001] The invention relates to an automatic anti-icing and deicing system for fan blades and an anti-icing and deicing method. Background technique [0002] Wind turbines are generally installed in damp and cold areas such as high mountains and frontiers with abundant wind resources, and blade icing has become one of the serious hidden dangers affecting their safe operation. Icing of fan blades leads to changes in the aerodynamic shape of the blades, which is one of the main factors affecting the safety and reliability of wind turbines. When a large number of blades are covered with ice, the efficiency of the wind turbine will decrease, and the output power of the turbine will decrease, which may lead to unplanned shutdown of the wind turbine and affect the power grid. The safe and stable operation of the system. Serious icing will also lead to blade breakage and damage to the unit. At the same time, the ice layer will fall off under the rotating state, whi...
