Background: I'm going to build a homemade wind turbine. It will be all fancy and rotational so that it's always pointing to the wind, so it will be mounted on a frame etc. This will be mounted on a pole that fits vertically through the roof of a barn.
However, the place I'm going to build it for quite often experiences high wind speeds that would probably cause the wind turbine to break or get damaged.
So, I would like the turbine to be retractable/extendable. My current best idea is to have a gear system and a handcrank, with some sort of worm-gear-esque arrangement at the pole end that will use the rotational force of the gear system to raise or lower the turbine.
- How best can I translate the energy from the gear system into raising/lowering force?
- Is there any way to lock the system so that the pole doesn't simply fall when I stop cranking, and can be raised/lowered safely by handcrank?
- Is this idea feasible to make by hand for an amateur with no background in engineering?
