Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power, and in particular to an offshore semi-submersible wind power foundation platform. Background Art

[0002] As the global energy structure transitions toward cleaner energy, offshore wind power, as an important form of renewable energy, has experienced rapid development in recent years. Offshore wind power foundation platforms are marine engineering structures that support and secure offshore wind turbines. They are mainly divided into two categories: fixed and floating. Fixed platforms include monopiles, jackets, gravity platforms, and tripods. They are directly fixed to the seabed through pile foundations or their own weight and are suitable for offshore areas with water depths of less than 60 meters. Floating platforms are connected to the seabed using an anchoring system and include semi-submersible, tension-leg, and buoy types. They can adapt to deep waters of more than 50 meters and have mobility and deep-sea development potential. Both types of platforms have the core function of resisting wind and wave loads and ensuring the stable operation of wind turbines. The choice of their structure depends on water depth, geological conditions, and cost factors.

[0003] Existing wind turbine platforms mostly rely on external power supply or a single power generation mode, failing to fully develop ocean wave energy resources, resulting in energy waste. At the same time, the buffering effect of existing wind turbine foundation platforms is poor, resulting in the wind turbines shaking greatly along with the foundation platform when affected by wind and waves, causing structural fatigue and damage to the wind turbines, affecting the service life of the wind turbines.

[0015] The present invention provides an offshore semi-submersible wind power foundation platform. It has the following beneficial effects:

[0016] 1. This offshore semi-submersible wind power foundation platform realizes multi-level positioning and locking of the wind turbine tower through a flange, mounting plate and a fixing clamping plate system driven by an electric push rod. During installation, the wind turbine tower can be quickly inserted between the circularly distributed mounting plate, push plate and fixing clamping plate, and the initial fixation is completed by installing bolts and flanges. The electric push rod further drives the fixing clamping plate to clamp the tower, forming a double fixation. This design improves the stability and safety of the wind turbine tower installation.

[0017] 2. This offshore semi-submersible wind power foundation platform uses a second buffer device to achieve horizontal energy dissipation through the coordinated action of hydraulic damping and springs. When the foundation platform is laterally impacted by waves, the first piston slides in the connecting cylinder, and the high-viscosity silicone-based hydraulic oil forms flow resistance through the liquid storage tube. At the same time, the first spring deforms to absorb the impact kinetic energy. The solenoid valve can adjust the oil flow rate and dynamically optimize the damping strength. This design significantly reduces the lateral swing amplitude of the tower, reduces stress concentration at the structural joints, effectively delays metal fatigue, and extends the service life of the platform.

[0018] 3. This offshore semi-submersible wind power foundation platform uses a disc spring group through the first buffer device to convert vertical vibration into elastic potential energy through the nonlinear deformation of the disc spring group. The buffer pad and limit block are used to limit the maximum deformation of the disc spring group to prevent overload damage. This design enables the platform to maintain the vertical stability of the tower under extreme conditions such as typhoons or huge waves, while avoiding damage to internal equipment due to rigid impact.

[0019] 4. This offshore semi-submersible wind power foundation platform uses a wave energy power generation device. The deformation of the airbag ball due to wave compression and the elastic force of the second spring drive the reciprocating motion of the second piston, which drives the movable frame to move back and forth, and the turntable drives the rotation of the shaft, so that the generator box generates electricity. The output of the generator box is stored in the battery box and can power the platform monitoring system, electric push rods and lighting equipment. The airbag ball adopts a carbon fiber grid reinforced structure, which is both explosion-resistant and elastic. It not only alleviates wave impact but also improves energy capture efficiency. This design realizes the recycling of marine energy, reduces the platform's dependence on the external power grid, and enhances its feasibility of deployment in remote waters.

[0039] When in use, when installing the wind turbine tower 1, the wind turbine tower 1 is hoisted into the installation column 2, and the wind turbine tower 1 is passed through the annular installation plate 17, the push plate 1406 and the fixed clamping plate 21, and the flange 8 is installed together with several installation plates 17 by installing bolts 9 to achieve preliminary fixation of the wind turbine tower 1, and then multiple electric push rods 19 are started to drive the fixed clamping plate 21 to approach and clamp the wind turbine tower 1, so that the wind turbine tower 1 is fixed for the second time, and the wind turbine tower 1 is firmly installed with the installation column 2, and the wind turbine tower 1 has a certain degree of freedom in the horizontal and vertical directions, wherein the telescopic rod 15 has a horizontal degree of freedom through the first connecting member 13 and the second connecting member 16, and the first connecting member 13 and the second connecting member 16 have a certain degree of freedom in the horizontal direction of the telescopic rod 15, and the first connecting member 13 and the second connecting member 16 have a certain limit on the horizontal rotation angle of the telescopic rod 15, so that the telescopic rod 15 can swing without affecting the normal operation of the wind turbine tower 1, and the first connecting member 1401 and the fourth connecting member 1405 are used to make the first connecting member 1 402 and the first movable rod 1404 as a whole have horizontal freedom, and the third connecting member 1401 and the fourth connecting member 1405 have certain restrictions on the horizontal rotation angle of the first connecting tube 1402 and the first movable rod 1404 as a whole, so that the first connecting tube 1402 and the first movable rod 1404 as a whole can swing slightly without affecting the normal operation of the wind turbine tower 1, and the elastic disc spring group 1103 can make the wind turbine tower 1 vibrate in a limited vertical direction. The top of the annular elastic waterproof cloth 5 is installed on the outer surface of the wind turbine tower 1 by the first screw 6, and the bottom of the elastic waterproof cloth 5 is installed on the outer surface of the top of the mounting column 2 by the second screw 7. The elastic waterproof cloth 5 is made of elastic material and is coated with a polyurethane waterproof coating on the surface. The elastic waterproof cloth 5 can not only prevent seawater from entering the mounting column 2, but also use its own elasticity to disperse the impact energy of waves, reduce fatigue damage of the elastic waterproof cloth 5, and make the elastic waterproof cloth 5 have a longer service life.

[0040] Through the first buffer device 11, when wind and waves occur, the basic platform composed of the installation column 2, the auxiliary column 3 and the connecting truss 4 shakes, and the vertical shaking causes the disc spring group 1103 to deform, so that a part of the vertical force transmitted to the wind turbine tower 1 when the basic platform shakes is converted into elastic potential energy by the disc spring group 1103, so that the vertical force on the wind turbine tower 1 is buffered, and the vertical shaking of the wind turbine tower 1 is reduced. By setting the buffer pad 12, the buffer pad 12 is used to limit the deformation degree of the disc spring group 1103 to prevent the disc spring group 1103 from being damaged by excessive extrusion and deformation, and the limit block 1106 set at the top of the guide rod 1105 can prevent the disc spring group 1103 from being over-stretched and damaged.

[0041] Through the second buffer device 14, when wind and waves occur, the basic platform composed of the installation column 2, the auxiliary column 3 and the connecting truss 4 shakes, and the horizontal shaking causes the first piston 1403 to slide along the inner surface of the first connecting cylinder 1402. High-viscosity silicon-based hydraulic oil is provided in the hydraulic oil chamber 1410 on one side of the first piston 1403. The movement of the first piston 1403 forces the hydraulic oil to enter and exit the liquid storage tube 1408 with a smaller inner diameter, and the first spring 1407 expands and contracts. The high-viscosity oil generates a large flow resistance when flowing in a narrow channel, and the first spring 1407 also generates a certain resistance when it expands and contracts, so that the horizontal force acting on the wind turbine tower 1 is buffered, thereby reducing the horizontal shaking of the wind turbine tower 1.

[0042] Through the wave energy power generation device 22, the airbag ball 2207 adopts a multi-layer nylon reinforced rubber airbag, which is filled with gas. The outer wall of the airbag is embedded with a carbon fiber grid to enhance the explosion resistance. When wind and waves occur, the airbag ball 2207 is deformed by the impact of the waves. Part of the gas in the airbag ball 2207 flows along the horn cover 2203 into the second connecting cylinder 2202. The second piston 2204 is pushed by the gas and moves along the inner surface of the second connecting cylinder 2202. The second spring 2206 is compressed accordingly. Under the elastic action of the second spring 2206 and the change of wind and waves, the second piston 2204 is compressed. 204 will also move in the opposite direction, so that the gas entering the second connecting tube 2202 returns to the airbag ball 2207, so that the second movable rod 2205 drives the movable frame 2211 to move back and forth. With the cooperation of the connecting column 2215 and the fixed teeth 2212 on its upper and lower sides, the turntable 2214 rotates, and the rotating shaft 2213 rotates accordingly. The generator box 2208 converts mechanical energy into electrical energy and stores the electrical energy in the storage box 2216 to realize wave energy power generation. At the same time, the elasticity of the airbag ball 2207 can provide a buffer to reduce the impact of waves on the installation column 2 and the auxiliary column 3.
