Embodiment Construction

[0021] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] A wind power blade with anti-icing and de-icing devices, including heat (blower) fan, air pipe, inner and outer membranes, membrane holder and other components. details as follows:

[0023] Such as figure 1 As shown, it includes an I-beam 1, on which a blade 3 is embedded and installed, and a double-layer diaphragm is installed on the windward side of the blade 3; The outer membrane 6 is formed after sealing its surroundings, and there are intermembrane gaps 7 between the diaphragms; the outer membrane 6 adopts a microporous hydrophobic membrane, and the inner membrane has no micropores.

[0024] Such as figure 1 As shown, the two sides of the double-layer diaphragm are tightened and fixedly installed by the diaphragm holders 4 located on both sides of the blade 3, or the two sides of the double-layer diaphragm are bonded together wi...

Abstract

The invention relates to the field of wind power technology, in particular to an anti-icing and de-icing device for a wind turbine blade. By means of the bionic principle, water drop adhesive force is reduced by means of a microporous hydrophobic membrane, water drops on the surface of the membrane are blown off by airflow, surface dryness of the blade is kept, and surface icing of the blade is prevented; ice accretion on the surface of the blade is broken and eliminated through expansion of the membrane after inflation. The device specifically comprises an air heater (blower), an air pipe, an inner membrane, an outer membrane, a membrane clamp base and the like, wherein the air heater (blower) is installed on an I beam of the blade and driven by a wind turbine generator, (hot) air is fed into the air pipe through the air heater (blower) and enters a gap between the inner membrane and the outer membrane through a quick plug connector, and the outer membrane is a breathable microporous hydrophobic membrane; the inner membrane and the outer membrane are sealed all round and fixed quickly by the membrane clamp base. The device has anti-icing and de-icing functions and is low in energy consumption. The device has important significance for safe, economical and efficient operation of wind turbine generators in cold and moist areas in winter.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power blade with an anti-icing and de-icing device. Background technique [0002] The world is undergoing a transformation oriented toward diversification and clean energy, optimized energy structure, and characterized by clean energy. As a clean and pollution-free renewable resource, wind energy has attracted more and more attention from all countries. With the continuous consumption of conventional resources, wind power generation will be a trend of future electric power development. Wind power has become an important part of my country's power structure. [0003] Wind turbines installed in cold and humid areas are plagued by ice accumulation in winter. Ice coating on the surface of wind turbine blades will change the aerodynamic profile of the blades, affect the aerodynamic characteristics of the blades, cause additional load and vibration of the wind tur...
