Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] In order to solve the existing problem of blade icing, the present invention discloses a method for anti-freezing and deicing of wind turbine blades based on solar energy reflection and concentration. Renewable resources, solve the problem of leaf icing through the amount of solar radiation, and generate almost no additional energy consumption in the process.

[0025] Such as figure 1 As shown, an anti-freezing and deicing device for wind turbine blades provided by the present invention includes a concentrating reflector 1 and a biaxial stepping tracking bracket 2, composed of multiple groups of reflecting mirrors 1 and a biaxial stepping tracking bracket 2 The reflective concentrator array is installed around the bottom of the wind turbine tower.

[0026] Each biaxial stepping tracking bracket 2 is equipped with a set of concentrating reflective mir...

Abstract

The invention provides an anti-freezing deicing device and method for the blades of a wind driven generator. The anti-freezing deicing device comprises a plurality of condensation reflection lenses installed at the bottom of a wind driven generator tower drum in a circumferential mode, and reflected light of each condensation reflection lens is incident to a rotating plane of the blades. The device solves the problem of blade freezing, so that the reliability of a wind generating set is improved, non-quality shutdown caused by deicing is avoided, and the power generation efficiency of a wind driven generator is effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of solar energy and wind power generation, and relates to an anti-freezing and deicing device and method for blades of a wind power generator. Background technique [0002] Wind power generation is one of the main power generation methods in the current renewable energy power generation system. In the humid and cold areas such as the northern alpine region and the central and southern mountainous areas in China, icing of blades and anemometers is a common problem in the operation of wind turbines. The icing of anemometers leads to measurement errors. The maximum can reach 60%, which seriously affects the control strategy of the wind turbine. At the same time, the icing of the blades affects the surface airfoil structure, affects the aerodynamic characteristics and power generation output, and affects the power generation characteristics by up to 50%. Icing blades will not only affect the power output of the fan, but a...
