[0024] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it. The embodiments are not intended to limit the present application. Please refer to Figure 1 and Figure 2 the drawings, the preferred embodiment of the present application is a three-dimensional view and an exploded three-dimensional view, which discloses a stabilizing device 100 of a floating platform, comprising:

[0025] a floating platform 10, comprising a plurality of (two or more) box-shaped pontoons 11 and a plurality of bearing columns 12, in the embodiment of the present application, the box-shaped pontoons 11 are plate-shaped pontoons, and the number is three, the box-shaped pontoons 11 are connected to each other to form a frame 13 in the shape of an equilateral triangle, and the corners 14 of the frame 13 are rounded, so that the outer periphery of the corners 14 of the frame 13 is in the shape of a circular arc, the bearing columns 12 are cylindrical columns, and the number is three, and are arranged in the longitudinal direction at the corner positions of the frame 13, the top surface of one of the bearing columns 12 is used to bear a wind turbine 15, and the wind turbine 15 can generate wind power.

[0026] A plurality of zero pressure air cushion devices 20, each of which is arranged in a built-in manner in the floating platform 10, the zero pressure air cushion device 20 is a space 21 which is open at one end and closed at the other end, in the embodiment of the utility model, the space 21 is a cylindrical hole, and is arranged in the corner portion 14 and the bearing column 12, the bottom of the space 21 is provided with an open opening 22 for water inlet, the opening 22 is communicated with the space 21, and the remaining space 23 after water inlet will be used as air damping, as shown in the figure, one side above the zero pressure air cushion device 20 is provided with a fluid release member 24, the fluid release member 24 is an oil pressure release valve, and is arranged in the bearing column 12, the fluid release member 24 is used to release the gas in the zero pressure air cushion device 20, so as to adjust the balance of the floating platform 10 when it is launched or counterweighted. Figure 3

[0027] The stabilizing device 100 of the floating platform of the utility model is used, first, a plurality of mooring lines (not shown in the figure) are connected to the floating platform 10, the tail end of each mooring line is provided with an anchor (not shown in the figure), and then the floating platform 10 is transported to the installation site by a floating dock ship and is moored and positioned.

[0028] When the floating platform 10 is just laid to reach the average water level, the zero pressure air cushion devices 20 will simultaneously inlet water from the openings 22, and the air in the remaining space 23 will be used as air damping, as shown in the figure. Wherein, the zero pressure air cushion device 20 is provided with the fluid release member 24, so that when the floating platform 10 is just laid and the water level has not reached the position, the gas in the zero pressure air cushion device 20 is released, so as to avoid the phenomenon that the floating platform 10 cannot reach the average water level (static stability) due to the change of the water level and the zero pressure air cushion device 20 cannot follow the adjustment, but causes the reverse effect phenomenon that the floating platform 10 cannot reach the average water level. Figure 3

[0029] When the floating platform 10 performs pitching or rolling motion, one side of the floating platform 10 will sink, and the other side will be lifted, as shown in the figure, the air in the zero pressure air cushion device 20 will generate a rebound force due to compression, the zero pressure air cushion device 20 provides damping inside the floating platform 10, thereby correcting the motion of the floating platform 10, reducing the oscillation amplitude, slowing down the motion of the floating platform 10 and changing the natural period, so as to improve the platform stability and the power generation efficiency of the wind turbine 15. Figure 4

[0030] It is worth mentioning that the zero pressure air cushion device 20 does not provide additional buoyancy, in addition to avoiding changing the original design, but also by providing damping to correct the motion response of the original floating platform 10 design, increase the adjustable space of the floating platform 10, to help the design and development of the floating platform 10.
