Description

Floating photovoltaic power generation structure

The present invention relates to a structure for supporting a solar module (Solar Module) in a floating floating solar power system, and more specifically, the shaking and flow of the solar module due to wind and swell in the floating state on the water. The present invention relates to a floating floating photovoltaic structure capable of improving power generation efficiency by minimizing and stably maintaining an optimal solar incident angle.

Recently, floating floating solar power systems installed on the water surface of rivers, lakes, reservoirs, dams, etc. can efficiently utilize the land by using the water surface as an idle site, and have less restrictions on slope and shade compared to the solar power on the ground. There is a cooling effect to prevent overheating of the solar module due to the low temperature of the power generation efficiency per area has a relatively high advantage.

In general, as shown in FIG. 1, the floating solar photovoltaic power generation system is fixed with a solar module 100 on a floating structure 102 floating on the water surface by buoyancy of the floating body 104, and floating. The structure 102 is connected to the anchor 106 and the wire 110 fixed to the ground for mooring.

In addition, the floating structure 102 is fixed at a specific position so as to be able to set the direction of the solar module 100 according to the azimuth of the sun to increase the power generation efficiency.

However, the floating structure 102 is easily shaken or moved freely even by small displacement and vibration caused by wind (wind load), swell, wind wave, wave (blue), etc., so that the angle of the solar module 100 installed thereon is inclined. Displacement occurs, and when this occurs, a problem such as damage to the solar module 100 and deterioration in power generation efficiency may occur as the angle of incidence set to absorb as much sunlight is distorted.

In addition, there is a problem in that the connecting portions of the mutually damaged parts are easily damaged when excessive tension is applied to the wire 110 moored to the floating structure 102.

On the other hand, Patent Document 1 buffers the shaking and flow of the support frame acting due to the wind and the sun with the elastic force of the damper with a built-in compression coil spring to stably stabilize the sunlight incident angle of the solar module in an optimal state. A marine photovoltaic device that can be sustained is disclosed.

However, it is composed by connecting several unit structures to overcome unstable support conditions caused by water movement, and vibration is caused by the expansion and contraction of the compression coil spring in the damper while setting the placement angle with the largest power generation efficiency of the solar module. And because the structure is to mitigate the impact, if the wind or swell occurs repeatedly, the direction of the compressed coil spring is periodically changed by the restoring force to return to its original state by forming an unbalanced state with the damper of other adjacent unit structures. Disturbing force occurs, and vibration and fluctuation of the support frame imposes a repetitive load on each part supporting the photovoltaic module, causing noise and disengagement of the main parts, causing failure. If severe, there is a problem of shortening the service life by causing deformation and damage to the main part.

The above-described background technology or prior art is only to help the inventors understand the technical significance of the present invention as information possessed or acquired in the process of deriving the present invention, and the technology to which the present invention belongs prior to the filing of the present invention It is revealed that it does not mean a technique well-known in the field, and the reference numerals in the prior art are mutually independent of the reference numerals in the present invention.
