<p>The present invention relates to a water circulation device for a water surface solar power generation device which can prevent the degradation of power generation efficiency for a solar power generation module caused by a rising temperature of the water surface, by vertically circulating the water with the use of fans. The existing water surface power generation device had a problem with the degraded power generation efficiency of the solar power generation module when the water surface temperature rises, but the present invention provides the water surface power generation device with multiple solar power generation modules installed at the top of a floating material, wherein a driving motor is combined at the top of the floating material and the rotation shaft of the driving motor penetrates the floating material and connects to the extended end in the water, and also, at the top of the fan; a fixed shaft is combined to a rotation shaft; multiple supporting units are fixed and vertically formed by a connection unit connected to the fixed shaft on the outer side of the fan; and the floating material and the supporting unit are connected through a frame. Thus, the present invention prevents the rising temperature of the solar power generation module caused by hot water and maintains the maximum amount of power generation by the solar power generation module by vertically circulating the cold water at the bottom to the normal temperature water at the top with the use of rotating fans. In addition, the present provides multiple supporting units which prevent damages to the fan caused by a contact to the ground and an elastic connection unit which prevents deformation or damage of a rotating shaft caused by vibrations from the wind or waves.</p> |
