The floating ball 5 can float on the water or the sea, and can support the structure arranged on the upper part of the floating ball 7. In this embodiment, the floating ball 7 is a hollow rubber ball inside, and the outside includes an iron sealing layer to form a spherical skin , To protect the rubber sphere, the iron skin is welded with an anti-rust block. Specifically, the anti-rust block is a zinc block. By setting the zinc block to prevent the iron sheet from rusting, the zinc block needs to be replaced regularly. In other embodiments, the number of floating balls 5 may also be multiple. The diameter of the floating ball 5 needs to be adjusted according to the weight of the structure disposed on the upper part of the floating ball 5, so that the buoyancy provided by the floating ball 5 is sufficient to support the structure disposed on the upper part thereof.

The supporting column 4 is arranged on the upper end of the floating ball 5 along the vertical direction. In this embodiment, the number of supporting columns 4 is four, and the top of the floating ball 5 is symmetrically arranged on the four supporting columns. The steel bar is connected to the surface of the floating ball 5 by welding, and the welded surface formed by welding is provided with an anti-rust layer. Specifically, it can be sprayed with anti-rust paint such as cold galvanized paint to form the anti-rust layer, and then concrete is poured to wrap the steel bar. Internal. The four support columns 4 are also connected into a whole through an elastic material. In this embodiment, the four support columns 4 are connected into a whole through an annular rubber ring 3 to improve the structural stability of the support columns 4. Moreover, the rubber ring 3 is light in weight and does not significantly increase the load-bearing capacity of the support column 4 .

The platform 1 is arranged on the upper end of the support column 4 in the horizontal direction, and structures such as substations and generators can be installed on the platform 1. Specifically, the platform 1 and the support column 4 are connected through the damper 2 to improve the platform structure. For stability, in this embodiment, the damper 2 is selected as the viscous damper 2 .

The steel strand 6 is arranged at the lower end of the floating ball 5, and the lower end of the steel strand 6 is connected to the anchor 7. The anchor 7 can contact the river bed or the seabed and be fixed, so that the floating ball 5 can be fixed, and the The length needs to be determined according to the distance between the lower surface of the floating ball 5 and the seabed, so that the anchor 7 can contact the riverbed or the seabed. 6 is welded in the middle of the top of the floating ball 5.
