Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, specifically to an emergency transfer device for wind turbine elevators. Background Technology

[0002] In response to the frequent wind turbine tower falls, such as the fall from the elevator in Lenghu, Qinghai on March 6 and the fall from the crossbeam above the elevator at Pearl Bay, Nanpeng Island, Yangjiang on February 25, Xinsheng Wind Farm investigated 20 wind turbines in the farm and found that there are serious safety hazards of falling when transferring personnel from the elevator to the ladder in the event of an emergency shutdown due to elevator malfunction: (1) The distance between the elevator and the ladder is large, with the longest straight-line distance being 1.5 meters and the shortest straight-line distance being 1.2 meters, posing a risk to shorter personnel during the transfer. (2) During the transfer, it is inconvenient to hang and remove the safety belt, posing a safety hazard. (3) Even if the safety belt is properly hung, the elevator car is not absolutely fixed during the transfer. The car will shift backward under the force during the transfer, which will further increase the transfer distance and make it very easy for similar safety incidents as those on March 6 and February 25 to occur.

[0003] By designing and installing an emergency fixed transfer device for sudden power outages in fan elevators, a stable foothold is created during the transfer of personnel from the elevator to the ladder in emergencies, greatly reducing the risk of falls and preventing accidents similar to those on March 6th and August 29th. Therefore, the installation of over-support and handrails is essential. Utility Model Content
