[0026] The embodiment of the present invention provides a stable support structure for the transportation of the offshore photovoltaic platform by setting a bottom plate 10, an intermediate plate 7 and a placement platform 1, thereby ensuring that the offshore photovoltaic platform is more stable during sea transportation. By providing a limit groove 2 on the placement platform 1, the support column of the offshore photovoltaic platform can be inserted into the limit groove 2 for position limiting, so that the center of gravity of the support column is concentrated, and the position of the support column is prevented from being offset during transportation, thereby improving stability. By designing the bottom plate 10 to be a structure that can be detachably connected to the deck, the support seat of the embodiment of the present invention can be easily disassembled and assembled with the transport ship, and the support seat can be reused repeatedly. The lower end surface area of ​​the placement platform 1 is designed to be smaller than the upper end surface area of ​​the intermediate plate 7 in order to install a lifting point 6 on the edge of the intermediate plate 7 to facilitate lifting the support seat.

[0027] It should be noted that the layout of the support base follows the layout of the support column of the offshore photovoltaic platform, and a support base of an embodiment of the present invention is arranged at the bottom of each support column.

[0028] When in use, first measure the position and distance of the support column of the offshore photovoltaic platform, and then install the support seat on the deck. When lifting, the bottoms of the six support columns of the offshore photovoltaic platform are respectively inserted into the corresponding limit grooves 2 of the support seat.

[0029] Furthermore, the limiting groove 2 is a flat cylindrical structure, and the inner diameter of the limiting groove 2 is matched with the outer diameter of the bottom of the supporting column.

[0030] Furthermore, the bottom plate 10 is fixedly connected to the deck by bolts.

[0031] In some embodiments, Figure 3 As shown, the cross section of the placing platform 1 is a square structure, and the center of the limiting groove 2 coincides with the center of the middle plate 7. This can concentrate the force of the support seat and improve the support stability.

[0032] In some embodiments, Figure 1 , 2 As shown, the upper end surface area of ​​the middle plate 7 is slightly larger than the upper end surface area of ​​the bottom plate 10, which can reduce the area of ​​the deck occupied by the support seat.
