Plate-free tray type offshore substation upper module
The invention provides a plate-free tray type offshore substation upper module which comprises two layers of frame type steel structures, each frame type steel structure is formed by beams, columns and inclined struts, and main columns, structural columns and inclined struts are arranged between the upper layer of beams and the lower layer of beams; a prefabricated cabin or outdoor equipment is connected to a beam or a column of the frame-type steel structure to form an integral offshore transformer substation upper module. According to the frame type steel structure, a beam system serves as a framework of the plate-free tray structure type, grating channel areas are only arranged on a channel area, an equipment overhaul area and an embarkation gathering area on two layers of trays of an upper module of the plate-free tray structure type offshore transformer substation, and ribs and steel bed boards are not arranged on all the areas. A two-layer steel structure arrangement mode is adopted, original third-layer and fourth-layer beams, columns, ribs, plates and the like are omitted, meanwhile, first-layer and second-layer ribs, steel bed boards and the like are omitted, the using amount of steel can be reduced by about 50%-60%, the weight of an upper module is reduced, and then the choices of construction ship machine equipment are increased.
本发明提供一种无板托盘式海上变电站上部组块，包括两层框架式钢结构，所述框架式钢结构由梁、柱和斜撑所形成，上下两层梁之间设置主柱、结构柱以及斜撑；所述框架式钢结构的梁或柱上连接预制舱或者室外设备，构成整体的海上变电站上部组块；所述框架式钢结构以梁系作为无板托盘结构型式的骨架，无板托盘结构型式海上变电站上部组块仅在两层托盘上的通道区、设备检修区和登乘集合区设置格栅通道区，所有区域均不设肋条和钢铺板。本发明采用二层钢结构布置型式，取消了原有三层和四层的梁、柱、肋条、板等，同时取消了一层和二层的肋条、钢铺板等，可减少钢材的用量约50%~60%，减轻上部组块重量，进而使得施工船机设备的选择余地增多。
