Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a deicing device for blades of a wind driven generator comprises a cabin 1, a generator 4 is fixedly connected inside the cabin 1, one side of the generator 4 is rotatably connected with a gear box 5, the gear box 5 is fixedly connected with the cabin 1, a transmission shaft 2 is rotatably connected inside the gear box 5, impellers 3 are symmetrically and fixedly sleeved on two sides of the outer wall of the transmission shaft 2, a machine head 6 is fixedly sleeved on the outer wall of one side, far away from the generator 4, of the transmission shaft 2, the machine head 6 is rotatably connected with the cabin 1 through a bearing, the machine head 6 transmits mechanical energy to the generator 4 through the transmission shaft 2 and the gear box 5 for generating electricity, meanwhile, the generator 4 radiates heat to the inside of the cabin 1, a plurality of openings are formed in one side, close to the gear box 5, of the outer wall of the machine head 6, three blades 8 are fixedly connected around the outer wall of the machine head 6, the blades 8 are blown by, and the directional inside in cabin 1 of aluminium post 7, transmission shaft 2 drives its outer wall both sides impeller 3 and rotates the inside hot-air that promotes cabin 1 inside and enters into aircraft nose 6, the air is conducted aluminium post 7 department and is circulated along the inside of aircraft nose 6 outer wall on opening discharge back to cabin 1, the outer wall rigid coupling of aluminium post 7 has a plurality of fins 9, aluminium post 7 gives off the heat to the inner space of flabellum 8 through fin 9, thereby the temperature of flabellum 8 is extremely low and carries out the heat exchange and reduce the temperature down owing to blowing of wind-force, simultaneously when winter, the heat that fin 9 gave out can melt or sublime the operation of cleaing away with the ice that condenses on the flabellum 8.
