I designed mechanical carts to clean coastlines, oceans,
seas, rivers and other bodies of water. See drawing below. Cart no. 1 can be pushed by water crafts
or even persons to make the drum spindle turn clockwise as it run through the
water and the debris. The theory is that the debris collected will be drawn to
the rear end and will gradually settle down the bottom of the cart. Inclined
chambers are provided so that the debris will stay at the back when the water
is agitated by the waves. The alternative is a motorized spindle that can alter
the design. Cart no. 2 can be pulled by vehicles or persons to make the drum
spindle turn clockwise as it tracks the sand and the debris. The theory is that
the debris will be collected by the spikes and dropped into the wire mesh cart.
You can call it beach comber. The concept is from golf where they have carts
that collect golf balls.
