Description

How to connect floating structures and structures

The present invention relates to a method of connecting a floating structure and a floating structure of a water-state photovoltaic power generating apparatus, and more particularly, to a floating structure of a floating photovoltaic power generation floating structure positioned below a water surface, And a method of connecting the floating structure and the structure.

In general, solar cells convert the sun's light energy into electrical energy. The minimum unit for generating electricity using the photoelectric effect is called a cell, and a plurality of cells are connected in series or in parallel to generate electric power. A photovoltaic power station (also known as a photovoltaic system) is a collection of structures mounted in series or in parallel with a plurality of photovoltaic modules.

Such solar power plants are generally installed on the land, which requires huge land acquisition costs and civil engineering costs, and the environment is destroyed because they are used mainly as a site by cutting down the mountains. In addition, when installed on the land, the solar modules are heated by the geothermal heat in the summer, thereby failing to effectively cool the solar modules. As a result, the power generation efficiency of the solar module is lowered.

In order to solve such a problem, a method of installing water on a lake, a river, a pond, a dam, or the like has been developed. Such a water photovoltaic power generation system is a power generation system using a plurality of floating solar photovoltaic floating structures in which a plurality of solar modules installed on a water surface together with a buoy are arranged. These floating photovoltaic power generation floating structures should not move out of the set range in a place where they are installed by water flow or wind force in floating state, and the floating structure should not rotate (pitch, roll, yaw). If the floating solar power floating structure of a floating solar PV system floats or rotates (pitch, roll, yaw) from the water surface, the alignment between the solar PV module is distorted, So that a plurality of floating solar photovoltaic system floating structures can be damaged.

1 is a view showing a conventional aquatic solar power generation structure.

Referring to FIG. 1 (a), an aquarium photovoltaic power generation structure is fixedly connected between a front row and a rear row equipped with a solar module by using a structural member so as not to be free, and has an operator's path for maintenance between them . 1 (a) shows a disadvantage in that the construction cost is increased due to the weight of the entire aquamarine solar power generation structure, and there is a risk of damage due to a local load when uneven reservoir bottoms are exposed due to drought in the reservoir. The rope is connected to the part located on the outer side of the whole connected structure and moored to the anchor at the bottom of the reservoir.

Also, FIG. 1 (b) and FIG. 1 (c) have been proposed by improving the prior art in FIG. 1 (a). 1 (b) and 1 (c), a water photovoltaic power generation structure has a structure in which a worker path is disposed between the front row heat of a structure having a solar module and connected to a hinge type at a height corresponding to the water surface I have. 1 (b) and 1 (c), there is little fear of damage due to local load when the bottom of the reservoir is uneven due to drought in the reservoir, but the rotation (pitch, roll, yaw) There is a fear that the operator may lose the balance when moving the passage, and there is a disadvantage that maintenance is difficult.

1 (b) and 1 (c) are vulnerable to rotation (pitch, roll, yaw) because the connection between the front row and the back row of the floating solar photovoltaic floating structure is hinge- . When the floating structure floating on the water rotates (Pitch, Roll, Yaw) due to external forces such as wind, the center of rotation is rotated based on a point on the plane where the floating structure of the aquamarine meets water surface.

At this time, the restoration force to be restored from the tilted state is the force applied to the rope. At this time, as the distance between the center of rotation and the force applied to the rope is larger, However, in the techniques of FIGS. 1 (b) and 1 (c), since the connection between the front row and the rear row is the height corresponding to the water surface, the restoring moment is small and the structure is vulnerable to rotation (pitch, roll, yaw) of the structure.
