Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Refer to accompanying drawing 1 to Fig. 3, this utility model embodiment provides a kind of MW class internal rotor directly-drive permanent magnet wind generating motor internal recycle cooling system, including the cabin 2 being connected with wind power generating motor 1, the pylon 3 being connected with cabin 2, it is arranged at the ventilating duct 4 in described pylon 3, the air intake vent connection pylon 3 of ventilating duct 4, the air outlet connection wind power generating motor 1 of ventilating duct 4。
The bottom surface in cabin 2 has a cabin floor 5, and ventilating duct 4 is fixed on cabin floor 5, and ventilating duct 4 must have certain length, so that ventilating duct 4 air below temperature is of a sufficiently low。Ventilating duct 4 comprises epimere ventilating duct 41 and hypomere ventilating duct 42, and the upper end open of epimere ventilating duct 41 is the air outlet of ventilating duct 4, and this air outlet connection wind power generating motor 1, the lower end of epimere ventilating duct 41 connects cabin floor 5 by securing member。Cabin floor 5 is provided with ring flat-plate 6, and the upper end of hypomere ventilating duct 42 is sheathed on the outside of ring flat-plate 6, and with hawser bolt tightly on the outside of ring flat-plate 6。The lower end of hypomere ventilating duct 42 extends downward tower bottom platform 9 place after atop a tower platform 8, the lower ending opening of hypomere ventilating duct 42 is the air intake vent of ventilating duct 4, tower bottom platform 9 is fixed an axial flow blower 7, the inlet air mask of ventilating duct 4 sets axial flow blower 7, and axial flow blower 7 in order to and to flow up the lower end gas of pylon 3 in the air intake vent suction ventilating duct 4 of ventilating duct 4。The lower end of epimere ventilating duct 41 is fixed on cabin floor 5 by this utility model, the upper end of hypomere ventilating duct 42 is fixed on the ring flat-plate 6 of cabin floor 5, ventilating duct 4 entirety can be rotated along with wind power generator group, during wind generating set yaw, can better adapt to yaw direction, it is to avoid rotate knotting。
In this utility model, ventilating duct 4 is not limited to one with the quantity of axial flow blower 7, it is possible to epimere ventilating duct 41 and hypomere ventilating duct 42 are divided into several sections, between multistage epimere ventilating duct 41 or multistage hypomere ventilating duct 42 use multiple axial flow blower 7 to connect。
Described ventilating duct 4 is overall adopts organic material to make, and organic material can be nylon etc.。Adopt organic material can alleviate the weight of wind power generating set, and there is good heat-proof quality, can prevent the air-flow inside and outside ventilating duct 4 from interfering。
