背景技术 Background technique

从整体上看，风力发电机组可分为风轮、机舱、塔架和基础几个部分。其中风轮是由叶片和轮毂组成。轮毂是将叶片和叶片组固定在转轴上的装置，它将风轮的力和力矩传递到主传动机中去。在对风力发电机组的维护中，轮毂内部的维护具有非常重要的意义,鉴于维护人员要进入轮毂内作业，虽然在工作人员进入轮毂内作业时，风轮是停止的，但若出现突发事故，工作人员进入后，轮毂突然旋转，工作人员将会跟随轮毂的旋转而旋转，因轮毂内接有很多线路，在旋转过程中，工作人员易被线路缠住进而生命安全难以保障。因此研制出一种轮毂安全装置以保障人身安全成为了一项首要任务。  On the whole, wind turbines can be divided into several parts: wind rotor, nacelle, tower and foundation. Wherein the wind wheel is composed of blades and a hub. The hub is a device that fixes the blades and blade groups on the shaft, and it transmits the force and moment of the wind wheel to the main drive. In the maintenance of wind turbines, the maintenance inside the hub is of great significance. In view of the fact that maintenance personnel have to enter the hub to work, although the wind wheel is stopped when the staff enters the hub, if there is an accident After the staff enters, the hub suddenly rotates, and the staff will rotate following the rotation of the hub. Because there are many lines connected to the hub, during the rotation process, the staff is easily entangled by the lines and life safety is difficult to guarantee. Therefore developing a kind of hub safety device has become a top priority to guarantee personal safety. the
