Embodiment Construction
[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0033] Such as Figure 1-Figure 2 As shown, the blade provided by the present invention includes: a blade body 11, an insulating web 12 and a heating assembly 13; a chamber 111 is provided in the blade body 11, the insulating web 12 is connected in the chamber 111, and the heating assembly 13 is installed On the insulating web 12 , there is a gap between the heating component 13 and the inner wall 112 of the blade body 11 .
[0034] By installing the heating assembly 13 on the insulating web 12 connected to the cavity 1...

The invention provides a blade and a power generation unit, and relates to the technical field of power generation equipment. The blade comprises a blade body, an insulating web and a heating assembly, wherein a cavity is arranged in the blade body; the insulating web is connected in the cavity; the heating assembly is mounted on the insulating web; and a gap is formed between the heating assemblyand the inner wall of the blade body. The blade solves the problem that easy drop is caused as the outer surface of the blade is covered with a carbon-like fiber heating resistance wire and the bladeis easily struck by lightning when an existing blade is subjected to electric-thermal ice removal. The heating assembly is mounted on the insulating web connected in the cavity of the blade, and theheating assembly keeps heat dissipation balance inside and outside the blade by utilizing heat generated in the blade, so that the effect of preventing icing is realized; and the heating assembly is mounted on the insulating web at the inner side, the heating assembly is not in contact with the inner wall, and air insulation between the heating assembly and the inner wall is realized, so that thelightning protection effect is better.
Description
technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a blade and a generator set. Background technique [0002] The fan blade is one of the core components of the wind turbine, and the design of the fan blade directly affects the performance of the fan. In winter, due to the low ambient temperature, the blades are easy to freeze, which will damage the blades after freezing, so deicing technology is usually required to prevent the blades from freezing. At present, there are three main types of fan blade deicing technologies at home and abroad: antifreeze coatings, gas thermal deicing and electric thermal deicing. According to research, the anti-freezing coating technology has almost no effect; both air-heat deicing and electric de-icing technologies can achieve the effect of deicing, but the reliability of the equipment is not high, the cost of technical transformation of a single machine is too high, and the eco...
