This
bird deterrent uses a flashing light and a buzzer as the
visual and acoustic deterrents. The horizontal shaft drives
a cam through a reduction gear. The cam operates a micro
switch which activates the deterrents. A low wind speed
allows a flap to move forward switching another micro switch
which switches on a motor to turn the cam . The entire structure
is kept facing into the wind by a tail fin. A turned wooden
block attached to a steel disk acts as a heavy base. The
casing is made from aluminium. This deterrent worked very
well. |

A 3 blade
propeller drives a cam through a reduction gear. The cam
operates a micro switch which activates a flashing light
and a buzzer which act as the deterrents. The body is made
from brass sheet with the pivot from the stand attached
near the front. The shape of the body and the position of
the pivot ensure that it points into the wind at all times.
Low wind speed allows a flap to pivot forwards thereby switching
on a motor that will turn the cam. A clear polycarbonate
top allows all parts to be seen with dismantling . This
structure worked very well. |
