So are those things on the sides water tanks with floats in them? Yes, if you had three or more of them, the umbrella will sit on the water and be balanced. But who would lug around three tanks of water, plus the umbrella, plus the levers and arms needed to make it work? And where does the person stand without having a pole going through him?
And PLEASE - do better drawings. Carefully annotate things (using the text tool, not handwriting via a mouse), and shade/hatch/colour things so that we know what is what.
Yes, that device will 'work' (if I understand your jibberish). But it will not be useable, and nobody would buy one.
