Description

Band Spring, Including Same, Solar Structure Earthquake-resistance Device and Solar Structure Earthquake-resistance System The present invention relates to a seismic system for solar power structures, and more specifically, to a band spring installed in a solar power structure that allows for visual inspection of whether replacement is necessary, a seismic device for a solar power structure including the same, and a seismic system for a solar power structure. Solar power generation is a technology that converts sunlight, an electromagnetic wave, into electrical energy using solar cells. It is gaining attention as an alternative energy source due to the simple equipment required for power generation and the depletion or rising costs of various energy sources. Such a photovoltaic power generation facility is composed of a photovoltaic cell, a storage battery, and a power converter, and can be positioned above the floor surface by being supported by a support structure as disclosed in Korean Registered Patent Publication No. 10-2438325, etc. In addition, as inventions and research are being conducted due to the recent increase in demand for seismic performance in solar power generation facilities, as disclosed in Korean Registered Patent Publication No. 10-1734139, etc., springs are added to the frame section that supports the solar power generation facility in a direction perpendicular to the ground to provide seismic performance in the longitudinal direction, and the frame section is connected with a cross frame to provide seismic performance in the lateral direction through the tension caused by the wires and turnbuckles included in the cross frame and the elasticity of the springs. However, conventional methods of achieving lateral seismic performance through the elasticity of springs have limitations in visually determining whether replacement is necessary due to aging or damage of the springs.
