The invention discloses a permanent magnetic direct driving wind turbine generator set device. The permanent magnetic direct driving wind turbine generator set device comprises a permanent magnetic direct driving wind turbine, a supporting rod, a sleeve pipe and a mounting seat. The sleeve pipe is coaxially arranged on the supporting rod in a sleeving mode, and the sleeve pipe is connected with the supporting rod through a third bearing. The mounting seat is fixedly connected to the side surface of the sleeve pipe. The end, far away from the sleeve pipe, of the mounting seat is fixedly connected with the permanent magnetic direct driving wind turbine. Multiple heat dissipation holes are formed in an outer shell of the permanent magnetic direct driving wind turbine. In addition, the permanent magnetic direct driving wind turbine and the mounting seat are coaxially mounted. A sleeve is arranged on the permanent magnetic direct driving wind turbine and the mounting seat in a sleeving mode. A first bearing and a second bearing are fixedly mounted in the sleeve. The first bearing is arranged on the permanent magnetic direct driving wind turbine in a sleeved mode. The second bearing is mounted on the mounting seat in a sleeved mode. A rotary shaft of the permanent magnetic direct driving wind turbine extends to the outer side of the sleeve and is connected with a fan. The permanent magnetic direct driving wind turbine generator set device can not only generate electricity, but also dissipate heat of the permanent magnetic direct driving wind turbine while generating electricity, and therefore the service life of the permanent magnetic direct driving wind turbine is prolonged.
Description
technical field [0001] The invention relates to the technical field of power generation devices, in particular to a permanent magnet direct drive wind turbine device. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the usable wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. The existing permanent magnet direct drive wind motor loves to start rotating to generate electricity under the drive of the fan, but the traditional permanent magnet direct drive wind motor tends to generate heat during the long-term rotation process, and the traditional permanent magnet direct drive wind motor cannot perform well Heat dissipation. To this end, we propose a permanent magnet direct drive wind turbine device. Contents of the in...
