Description
Technical Field
The utility model relates to the field of offshore photovoltaic array supports, in particular to a pile foundation fixed type offshore photovoltaic array support.
Background
The land fixed photovoltaic support can be divided into single support and double support according to the number of section supports. The double-column photovoltaic supporting structure mainly comprises main beams, secondary beams, front struts, rear struts, inclined struts, double-column foundations and other key components. The double-column photovoltaic supporting structure is characterized in that a main beam and a secondary beam are supported by a front post, a rear post and an inclined support, and a photovoltaic module is supported by the main beam and the secondary beam. The connection between the front and rear 2 struts and the foundation is achieved by welding or bolting. The single-column photovoltaic supporting structure mainly comprises main beams, secondary beams, front supports, rear supports, steel columns, anchor clamps, a single-pile foundation and other key components. The single-column photovoltaic supporting structure adopts 2 inclined supports to prop up the main beam and the secondary beam, so that the photovoltaic module is supported, and the connection between the steel inclined supports and the single-column foundation is realized through the anchor ear, so that the single-column photovoltaic supporting structure has the characteristics of simplicity and high efficiency. The land photovoltaic can be used for determining the form of the photovoltaic array bracket through technical and economic comparison from the aspects of bracket steel materials, pile foundation engineering quantity, construction period, space utilization and the like.
The pile foundation cost corresponding to the photovoltaic single-pillar or double-pillar photovoltaic array in the country is not large in the ratio of the whole construction cost of the photovoltaic project, so that the general array is composed of 1-2 strings, the requirements of general dispersion and relatively complex topography of land photovoltaic land can be met, and the steel consumption of the photovoltaic bracket can be reduced as much as possible by the array with smaller capacity. However, as pile foundation fixed type offshore photovoltaic, in addition to the increase of wind load, various other special complex load working condition combinations of ocean currents, ocean waves, sea ice and the like are considered as compared with land photovoltaic; meanwhile, in order to avoid the direct slapping of the photovoltaic module by ocean waves, the top mark height of the support is higher than the design high tide level by a certain height so as to ensure the normal operation of the photovoltaic power station. Therefore, in the pile foundation fixed type offshore photovoltaic project, the pile foundation has a proportion of the whole construction cost of the project to that of the land photovoltaic project, and the pile foundation cost has a great influence on the income of the offshore photovoltaic project.
And at present, no support is designed for the high-capacity pile foundation fixed type offshore photovoltaic array, if the land array scheme is still considered to be applied to the pile foundation fixed type offshore photovoltaic project, the engineering quantity of the project pile foundation, the pile foundation construction and support mounting workload and the quantity of connected low-voltage alternating current cables are all increased due to the large number of arrays, so that the engineering cost is greatly increased.
