Description

Technical Field

[0003] The existing technologies close to the present invention are the manual installation technology of flexible bracket components and the construction cable hoisting installation technology of offshore cable photovoltaics. The manual installation technology of flexible bracket components is to manually transport a single photovoltaic component to the cable structure, and the installation workers use scaffolding or aerial work to rise to the installation position, and then manually install and fix the component to the cable structure. The construction cable hoisting installation technology of offshore cable photovoltaics is to set a cable crane on the construction cable, transport the module to the bottom of the installation position by ship, and the cable crane hoists the module to the installation position. The installation workers use the walking rope to reach the installation position, and then manually install and fix the module to the cable structure.
