A sliding sleeve is fixedly connected to the center of the body and is located on the opening side of the body. The sliding sleeve is movably sleeved on the lower end of the connecting rod four. Multiple connecting rods five are fixedly connected to the inner surface of the body. Each connecting rod five extends outward from the connection point between the sliding sleeve and the body. Multiple support rods two are fixedly connected to the outer circumferential surface of the sliding sleeve. The other end of the support rod two is connected to the corresponding connecting rod five.

[0007] Preferably, the installation platform further includes support column one, support column two, and support rod one. Support rod one is vertically connected between support column one and support column two. Support column one and support column two are coaxially arranged, and support column one is located above support column two. The installation platform includes three pontoons.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] like Figure 1-2 As shown, a floating wind turbine installation platform includes a support column 11, a support column 2 13, a support rod 1, a connecting rod 12, a connecting rod 2, a connecting rod 3 14, and a float 10. The support rod 1 is vertically connected between the support column 11 and the support column 2 13. The support column 11 and the support column 2 13 are coaxially arranged, and the support column 11 is located above the support column 2 13. There are three connecting rods 12, 2, 3, and three floats 10. The three floats 10 are vertically arranged and located on the periphery of the overall structure of the support rod 1, the support column 11, and the support column 2 13. The three floats 10 are connected to each other to form a triangular structure through the connecting rod 3 14. The support column 2 13 is connected to each float 10 through the connecting rod 2 2, and the support column 11 is connected to each float 10 through the connecting rod 12.

[0019] like Figure 1 ,2 As shown in this embodiment, the connecting rod, support column, and support rod 1 are connected to form a support frame with a triangular pyramid structure.

[0020] The connection structure under each pontoon is the same; let's take one of the pontoons as an example.

[0021] like Figure 3 , 4 As shown, the bottom end of the pontoon is connected to the connecting rod 4. A circular heave plate 3 is fixedly sleeved on the connecting rod 4. The outer edge of the circular heave plate is provided with an upwardly folded and extended skirt plate 13. The lower end of the connecting rod 4. is movably connected to the sliding sleeve 6 of the umbrella-shaped heave plate 7. A hydraulic damper 9 is sleeved on the connecting rod 4. between the sliding sleeve 6 and the circular heave plate 3. One end of the hydraulic damper is fixedly connected to the bottom end of the circular heave plate 3, and the other end of the hydraulic damper is fixedly connected to the sliding sleeve 6. The sliding sleeve 6 can slide on the connecting rod 4. When sliding upward, it compresses the hydraulic damper 9, and when sliding downward, it stretches the hydraulic damper.

[0022] The umbrella-shaped sway plate 7 includes an upward-opening, bowl-shaped body with a rigid structure. A sliding sleeve 6 is fixedly connected to the center of the body. Multiple connecting rods 5 are fixedly connected to the inner surface of the body, each extending outward from the connection point between the sliding sleeve and the body. Multiple support rods 4 are fixedly connected to the outer circumferential surface of the sliding sleeve 6, with the other end of each support rod 4 connected to a corresponding connecting rod 5. The support rods 4, connecting rods 5, sliding sleeve 6, and body are fixed together to form a single unit.

[0023] The umbrella-shaped sway plate 7 is subjected to the action of water flow, which pushes the sliding sleeve 6 to move up and down, causing the hydraulic damper to compress or stretch, resulting in motion damping effect.

[0024] Working principle: In use, multiple platforms as described in this invention are used to install the main body of the wind turbine on multiple support columns 11. The main body of the wind turbine exerts downward pressure on the installation platform, and the water exerts upward thrust on the installation platform. The forces cancel each other out by acting on the hydraulic damper, forming a strong damping effect, providing hydrodynamic damping for the floating wind turbine, thereby improving the overall vibration reduction effect of the floating wind turbine platform.

[0025] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
