Embodiment 1

[0036] Such as Figures 1 to 3 As shown, this embodiment provides an air-heat anti-icing anti-icing air duct for wind power blades, which is formed by splicing a plurality of structural units, and the number of structural units can be determined according to the system design. In this embodiment, the structural unit is Ω-shaped, the upper part of the outer protective layer 1 is arc-shaped, and the arc-shaped inner surface is rough; the inner surface is rough to facilitate fixing with the inner layer of insulation; The inner surface of the layer should be pasted with release cloth to ensure the roughness of the inner surface of the outer protective layer.

[0037] Such as figure 1As shown, the structural unit includes an outer protective layer 1 and an inner thermal insulation layer 3. The inner thermal insulation layer 3 is made of a material with low thermal conductivity. In this embodiment, polyurethane is used, which can play a better role in thermal insulation and preven...

Embodiment 2

[0048] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that, in this embodiment, the inner layer insulation layer also includes an embedded glass fiber reinforced plastic layer 6; the middle and inner layer insulation layer of this embodiment is not integrally formed, and the specific preparation method is include:

[0049] S1. prepare a thinner layer of embedded FRP layer 6 by winding molding or pultrusion molding process, the thickness of FRP layer 6 is less than 1mm; the embedded FRP layer 6 ensures the flatness and smoothness of the inner surface of FRP of the inner layer, and another On the one hand, the upper inner protective layer and the lower inner protective layer play a connecting role;

[0050] S2. Prepare a mold for foam foaming, the mold includes an upper half mold and a lower half mold, and the upper half mold and the lower half mold are respectively foamed and filled with polyurethane foam to form an upper inner layer ins...

Abstract

The invention discloses a wind power blade gas-heat anti-icing and deicing air guide pipeline and an installation method thereof. The wind power blade gas-heat anti-icing and deicing air guide pipeline comprises a plurality of construction units which are spliced, each construction unit comprises an outer protection layer and an inner heat insulation layer, the inner heat insulation layer is madeof a material with a low heat conductivity coefficient, the inner heat insulation layer is provided with a cylindrical air guide channel, and the two ends of the cylindrical air guide channel are respectively provided with a socket convex head and a socket concave part which are used for mutual connection of the construction units; the inner surface of the outer protection layer is attached to theouter surface of the inner heat insulation layer, and the outer protection layer is also provided with a fixed installation wing. The inner wall of the cylindrical air guide pipeline has small wind resistance, thereby facilitating hot wind transfer; meanwhile, the fixed installation wing is arranged, thereby greatly facilitating mounting and fixation and saving the installation time and the laborcost of installation; and the inner heat insulation layer reduces heat loss in the air guide process, thereby improving the anti-icing and deicing power of the system.

Description

technical field [0001] The invention belongs to the field of anti-icing and deicing of wind power blades, and in particular relates to an air-heat anti-deicing air guide duct for wind power blades and an installation method thereof. Background technique [0002] Wind turbines will reduce power generation efficiency or even shut down due to icing of blades, increasing the weight of blades will bring additional load to the unit, and at the same time, the falling ice will also threaten the safety of people and animals around; two mainstream active deicing solutions at home and abroad are gas heat Anti-deicing and electric heating anti-icing; electric heating anti-icing is easy to cause lightning due to electric heating elements, so there is a greater risk in lightning protection; in areas with a high probability of lightning strikes, gas thermal anti-icing technology has been widely used; in wind farms There are a large number of installed wind turbines that cause serious power...
