In general, floating structures for various purposes such as artificial plant islands, floating solar power generation, and cage fish farms are installed on water surfaces such as rivers, lakes, and the sea. In particular, solar power generation devices installed on the water are gradually increasing because they can solve problems such as indiscriminate development and environmental pollution on land that occur when installing solar power generation devices on land on farmland or forests.

Such floating structures generally include a floating body that provides buoyancy, and various types of frames and scaffolds may be installed to suit the structure to be installed on the floating body.

In particular, the floating body has high resistance as it is exposed to water flows such as waves and currents, that is, fluids. In particular, when a floating building including the floating body travels along a specific path, the traveling speed of the floating body may be reduced due to resistance to the fluid. Furthermore, the floating body may be easily damaged by fluid.

Embodiments of the present invention provide a floating body that can improve running speed or durability by reducing resistance to fluid.

It includes an anti-rotation pin that suppresses rotation along the floating portion, a resin coating portion provided to surround the floating portion, and a cover film provided to entirely surround the resin coating portion, and the floating portion has a center portion at both ends along the first direction. It is equipped to suppress resistance to water by having a vertical cross-sectional area that becomes smaller the further away from it.

In one embodiment of the present invention, the floating portion may include both ends each having a cone shape.

In one embodiment of the present invention, the anti-rotation pin may be provided to extend in a radial direction from the outer edge of the frame and penetrate the floating portion.

A floating platform according to an embodiment of the present invention includes a plurality of water floating bodies according to claim 1; and a stage disposed on top of the floating bodies, wherein the frames are coupled to each other in a matrix form.

Floating bodies according to embodiments of the present invention include a resistance suppressor and an anti-rotation pin. Accordingly, the resistance suppressing portion has a vertical cross-sectional area that decreases as the distance from the center of the floating portion increases, so that the resistance suppressing portion can suppress resistance to water.

Meanwhile, the rotation prevention pin is located between the floating part and the frame and can prevent the floating part from rotating along the circumference of the frame. As a result, the floating portion can generate a certain buoyancy force to the floating body.
