As a kind of improvement of the present invention, the two side of the front end of described buoyancy aid is circular-arc guide face.After adopting this kind structure, the guide face of the two side of described buoyancy aid front end has the effect of water conservancy diversion, increases the flow velocity of buoyancy aid both sides, thereby strengthens the power that is applied on the impeller.
As another kind of improvement the of the present invention, described speeder and generator are located at the top of described buoyancy aid; The middle and lower part of described buoyancy aid is located in described water filling chamber, and this water filling chamber is confined chamber with water mouth.This kind is designed to optimum implementation.
Also have a kind of improvement as of the present invention, described two impellers are installed on the both sides of described buoyancy aid by bearing and bearing support respectively, the center of each bearing saddle bore to the beeline of buoyancy aid bottom all greater than the radius of impeller.After adopting this kind structure, can give full play to the guide functions of guide face.
Described mooring system comprises anchor chain and anchor; One end of described anchor chain is connected the front end of described buoyancy aid; The other end of described anchor chain is connected on the described anchor.After adopting this kind structure, during use, the described anchor seabed of holding, under the effect of current, buoyancy aid is automatically to water, makes this electricity generating device have automatically the function to water.
Also have a kind of improvement as of the present invention, described impeller comprises the multi-disc blade; Every blade is provided with the water surface and back side, and described blade makes the blade-shaped camber from the water surface is protruded out to the back side direction; Two relative blades couple together and form S shape on the described impeller.After adopting this kind structure, it is logical that arc shaped blade more can hinder current, so just more can increase the power of impeller, further improves the generating efficiency of electricity generating device.
