<p>A flapping wing swimming device comprises a flat plate body(1), whereinsymmetrical side wings(4) are arranged at two sides of the plate body(1), and long through holes(3) are arranged at sides of the side wings(4).The middle portion in the front of the plate body(1) protrudes forwards; the plate body(1) is gradually thinned from the front side to the rear side.The lateral vertical surface at the periphery of the plate body(1) is in arc shape. When in use, the plate body(1) can float on water surface, and a swimmer prostrates on the plate body(1), holds sides of the long through holes(3) on the side wings(4) with two hands and sways the side wings(4) up and down, and the side wings(4) fly in water just as wings of a flying bird while the swimmer performs flapping action with feet so as to smoothly move forwards. The plate body(1) can generate enough buoyancy force to human body and does not need to be worn, thus being comfortable and convenient to use; and extremely strong interest can be achieved.</p> |
