Description

Floating type construction

The present invention relates to a water structure, and more particularly, to a water structure configured to suppress movement and posture changes caused by water flow and waves.

Generally, various kinds of water structures are installed and operated in rivers or lakes. For example, a water structure equipped with photovoltaic members is installed in a river or a lake.

Unlike solar power generation, which generates energy using heat generated after receiving heat from solar light, photovoltaic power generation has the principle of generating electricity directly from solar cells made of semiconductor materials by receiving sunlight.

Such photovoltaic power generation is a power generation method using a solar cell that generates photovoltaic power by photoelectric effect when light is irradiated, and is generally a module, a storage battery, and a power conversion device composed of a solar cell. It is composed.

1 is a perspective view of a water structure having a solar power installation, the water structure 10 is a plate-like floating member 11 floating in the water surface, a plurality of solar cell modules disposed on the upper surface of the floating member 11 12 and related members (eg, power converters and accumulators).

Here, the solar cell module 12 and related members required for power generation are generally used for photovoltaic power generation. The solar cell module 12 is modularized by connecting a plurality of solar cells. In the solar cell, an embedded semiconductor material receives sunlight to generate electricity. Each solar cell module 12 is rotatably supported by a support, so sunlight can be incident almost perpendicularly to the solar cell module 12.

Riversides such as rivers and lakes, and areas except lakesides have natural conditions without obstacles affecting the irradiation of sunlight, such as trees and rocks, and thus, aquatic structures equipped with photovoltaic members as described above (10) Can be installed in rivers or lakes to maximize power generation efficiency.

The vertical position change of the aquatic structure 10 does not have a great influence on the solar light incident on the solar cell module 12, but the left and right movement and the forward and backward movement of the aquatic structure 10 on the water surface are applied to the solar cell module 12. It has a large influence on the incident amount of incident sunlight, and thus can act as a large factor in determining the power generation capacity and power generation efficiency.

In rivers, water always flows in a constant direction (upstream to downstream), and therefore, the floating member 11 of the water structure 10 has no choice but to move from upstream to downstream in accordance with the flow of this water. In addition, the floating member 11 may be pushed to any one of both eyes of the steel by the irregular flow of water.

For this reason, if the water structure 10 moves downstream or both eyes, the power generation efficiency of the solar cell module may be lowered, and also difficult to maintain the power generation equipment.

In lakes with relatively little water flow, winds with high winds are often blown due to the topographical influence, which causes waves on the lake surface. Due to such waves, the position and attitude of the water structure installed in the lake changes, and the change of the position and attitude of the water structure also greatly affects the power generation efficiency.

The present invention is to solve the problem of the water structure installed on the water surface of the river or lake caused by the flow of water and the surface of the water surface, to provide a water structure that can maintain its position even by the water flow and waves. There is a purpose.

Here, the first cable has a first end fixed to the upper end of the post member, and the second end is fixed to one of the two sides of the steel. In addition, the second cable has a first end fixed to the upper end of the post member, and the second end is fixed to the other river side of both eyes of the steel.

Preferably, the first and second cables of the first support means are arranged in a straight line and are perpendicular to the post member. Further, the first and second cables of the first support means are preferably arranged in a direction perpendicular to the flow direction of the river.

Here, the second ends of the first and second cables of the first support means may be fixed to the structures installed on both riversides, respectively.
