Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and particularly to a sea-suspended cable photovoltaic support structure with adjustable component inclination and an installation method thereof. Background Art

[0002] Existing beach photovoltaics and nearshore offshore photovoltaics mostly adopt the form of fixed brackets, which have a large overall engineering steel consumption and are relatively difficult to maintain in the later stage. Therefore, a sea-suspended cable photovoltaic bracket can be adopted. However, when it is specifically applied to the construction of offshore photovoltaic projects, the following problems still need to be solved:

[0003] 1) There are generally two traditional arrangement methods for sea-suspended cable photovoltaic components. One is horizontal arrangement. The production of photovoltaic module groups is simple and the installation is also simple, but the optimal light angle cannot be achieved, and the power generation of the components is poor. The other is to tilt the module southward. This method can achieve the optimal light angle and the power generation is higher than that of the horizontal arrangement, but the structure of each module is different, the module production is complex and the installation is inconvenient. To increase the power generation of photovoltaic components, the components are arranged as much as possible to tilt southward to achieve the optimal light angle, and the module production and installation are as simple as possible.

[0004] 2) It is difficult for people to access traditional sea-suspended cable photovoltaic components. However, cable laying during the construction period requires people to access, and maintenance and repair during the operation period also require people to access. Therefore, construction, operation and maintenance are very inconvenient and unsafe. It is necessary to consider how to conveniently solve the problems of construction, operation and maintenance, and to set up convenient pedestrian passages and cable passages as much as possible.

[0005] Based on the above problems, how to increase the power generation of offshore photovoltaics and make its construction, operation and maintenance convenient is an urgent problem to be solved by the current sea-suspended cable photovoltaic support structure. Summary of the Invention

The support of the southern component cable structure 41 is low and is installed on the support pile support 31, while the support of the northern component cable structure 41 is high and is installed on the truss support 33. The component truss 6 (i.e., the photovoltaic component module) is arranged in the east-west direction and is fixed on the cable structure. A south-facing inclined plane is naturally formed by the height difference between the truss support and the support pile support.
