Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0033] like Figures 1 to 9 A kind of anti-icing wind power generation blade shown, comprises blade body 1, is provided with the deicing device 10 that can prevent wind power generation blade from icing on described blade body 1, and described deicing device 10 is carbon nanotube heating Wire 2, the carbon nanotube heating wire uses a non-metal-doped carbon nanotube electrocatalytic material, which has the advantages of high heating rate, energy saving and environmental protection, and is not limited by any external dimensions, and does not require miscellaneous wiring. The electrothermal conversion rate reaches more than 95%, which is unmatched by the current traditional resistance heating mode. After the carbon nanotube heating wire 2 is installed and arranged, the carbon nanotube heating wire 2 is covered and reinforced with a wear-res...

Abstract

The invention discloses an anti-icing wind power generation blade. The anti-icing wind power generation blade comprises a blade body, deicing devices capable of preventing the wind power generation blade from icing are densely distributed on the surface of the blade body, and the deicing devices are carbon nanotube heating wires; a cavity is formed in a blade root position of the blade body, and an electrifying device connected to the carbon nanotube heating wires for electrifying is arranged in the cavity; and a moving device capable of driving the electrifying device to move outwards from the cavity is arranged on the electrifying device, and an electromagnetic seat capable of enabling the moving device to move through magnetic adsorption is arranged on one side of the moving device. According to the anti-icing wind power generation blade, deicing can be realized by coating the carbon nanotube heating wires or carbon nanotube heating coating material on the blade body, micro size does not influence the aerodynamic shape of the blade, heating and deicing can be carried out without shutdown, electrifying can be realized through using electromagnetic connection, the complexity of construction can be further reduced, and a more convenient and reliable solution is provided for the deicing problem of the whole wind power generation field.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to an anti-icing wind power generation blade. Background technique [0002] The low temperature environment has brought severe tests to the blades and even the entire fan. As far as the blades are concerned, the low temperature environment will cause problems such as blade icing, material and structural performance changes, and load changes. In inland areas, especially mountainous areas, large Fans of all sizes are affected by icing problems both in operation and in shutdown. Low temperature factors affect fan design in many ways: Ice and frost and the increase in air density at low temperatures have a significant impact on the aerodynamics of the fan, which in turn affects the load and power output of the fan. Low temperatures will cause a greater mass of ice to attach to the blades, which will change the frequency of the fan blades and thus change their dynamic response behav...
