In the present embodiment, the third sleeve 24 is mounted on the mandrel portion 212 by a pair of bearings 26. In order to facilitate the mounting of the bearing 26, mounting steps are provided correspondingly inside the core portion 212 and the third sleeve 24. The third sleeve 24 is provided with a liquid discharge port 241 and a liquid inlet 242. The liquid outlet 241 and the liquid inlet 242 are connected to the hydraulic pump 12 through a connecting pipe 18 to provide work for the hydraulic pump 12. liquid. The annular liquid outlet communication groove 215 and the liquid inlet communication groove 216 of the mandrel portion 212 are respectively disposed at positions corresponding to the liquid outlet port 241 and the liquid inlet port 242. The liquid outlet communication tank 215 is separated from the liquid inlet communication tank 216, and the liquid outlet port 241, the liquid outlet communication tank 215, and the liquid outlet conduit 213 are in communication; the liquid inlet port 242, the liquid inlet communication tank 216, and the inlet The liquid conduits 214 are in communication. In order to prevent leakage of the liquid, the mandrel portion 212 is provided with a seal ring 27 such as an oil seal ring on the side walls of the upper and lower sides of the liquid discharge communication groove 215 and the liquid inlet communication groove 216.
工作时， 叶轮随风向的改变而转动， 带动液压泵 12转动，液压泵 12带动 底板 25转动， 由于底板 25固定安装在所述第一套筒 22上， 而第一套筒 22 通过轴承 26安装在芯轴部 212上， 从而使得所述底板 25可以绕所述芯轴部 212旋转， 从而使得叶轮可以旋转。 此时， 由于液压泵 12同时也在旋转， 由 于所述第三套筒 24也是通过轴承 26安装在芯轴部 212上， 因此， 第三套筒 24也会在连接管 18道的带动下随着液压泵 12旋转， 避免了连接管 18道的打 结。 而在第三套筒 24旋转的过程中， 由于环状出液连通槽 215和进液连通槽 216的存在， 使得出液口 241和出液管道 213、 进液口 242和进液管道 214 终保持连通状态， 因此使得液压泵 12可以连续的正常工作。 During operation, the impeller rotates with the change of the wind direction, causing the hydraulic pump 12 to rotate, and the hydraulic pump 12 drives the bottom plate 25 to rotate. Since the bottom plate 25 is fixedly mounted on the first sleeve 22, the first sleeve 22 passes through the bearing 26. Mounted on the mandrel portion 212 such that the bottom plate 25 can be rotated about the mandrel portion 212 such that the impeller can rotate. At this time, since the hydraulic pump 12 is also rotating at the same time, since the third sleeve 24 is also mounted on the mandrel portion 212 through the bearing 26, the third sleeve 24 is also driven by the connecting pipe 18 The hydraulic pump 12 rotates, avoiding the knotting of the connecting pipe 18. And during the rotation of the third sleeve 24, due to the annular liquid outlet communication groove 215 and the liquid inlet communication groove The presence of 216 allows the outlet port 241 and the outlet conduit 213, the inlet port 242, and the inlet conduit 214 to remain in communication, thereby allowing the hydraulic pump 12 to operate continuously.
