Description

Technical Field

[0001] The utility model belongs to the technical field of offshore wind power, and in particular relates to a movable operation and maintenance ship berthing and cage aquaculture system. Background Art

[0002] In recent years, with the intensification of global climate change, countries have proposed low-carbon and environmentally friendly development strategies. As the world's largest energy consumer, China has also actively responded and formulated the national dual carbon goals, namely carbon peak and carbon neutrality. The realization of this goal requires the development of clean energy, especially the widespread application of renewable energy. As an important part of clean energy, offshore wind power has huge development potential.

[0003] At present, offshore wind power is still mainly based on fixed foundations. In order to facilitate the docking of ships for operation and maintenance, wind turbine foundations are generally equipped with fixed mooring structures. Due to factors such as structural space and cost, SA300 rubber fenders were generally installed on mooring components in the early days. However, due to the low impact energy of the rubber fender, the rubber fenders were often damaged just after the wind farm was built. Subsequent wind farms often cancelled the rubber fenders, causing damage to the coating of the mooring steel pipes, followed by serious rust and collision damage. Utility Model Content

[0004] The utility model aims to overcome the deficiencies in the prior art and provide a movable operation and maintenance ship berthing and cage culture system.

[0020] Embodiment 1

[0021] As an example, Figure 1 and Figure 2 As shown, this movable operation and maintenance ship berthing and cage aquaculture system includes: a wind turbine single pile foundation 1-1, a movable rubber ring, a cage and a concrete frame 5;

[0022] The concrete frame 5 is arranged on the seabed around the wind turbine monopile foundation 1-1, and several layers of movable rubber rings are placed at different heights of the wind turbine monopile foundation 1-1. Figure 1 As shown, the layers of movable rubber rings are, from top to bottom, a first movable rubber ring 2-1, a second movable rubber ring 2-2 and a third movable rubber ring 2-3.

[0023] Net cages are provided between adjacent movable rubber rings and between the third movable rubber ring 2-3 and the concrete frame 5, and the net cages are the first net cage 4-1, the second net cage 4-2 and the third net cage 4-3 from top to bottom.

[0024] The inner sides of several layers of movable rubber rings are connected to each other through the inner support beam 3-2 of the rubber ring, and the outer sides are connected to each other through the outer support beam 3-1 of the rubber ring. The net box is a flexible telescopic structure. The movable rubber ring, the net box, the outer support beam 3-1 of the rubber ring and the inner support beam 3-2 of the rubber ring form a floating system. The floating system moves up and down along the wind turbine single pile foundation 1-1. The third movable rubber ring 2-3 is connected to the concrete frame 5 through the third net box 4-3 and fixed on the seabed. The movable rubber ring, the outer support beam 3-1 of the rubber ring and the inner support beam 3-2 of the rubber ring are all hollow structures with a certain buoyancy, so that the first movable rubber ring 2-1 can always float above the sea level. In this embodiment, according to the height of the operation and maintenance ship, the first movable rubber ring 2-1 is always about 2m above the sea level, which is convenient for the ship to directly land on the first movable rubber ring 2-1 when berthing, so as to avoid damage to the coating of the berthing steel pipe.

[0025] The diameter of the concrete frame 5 is larger than the diameter of the movable rubber ring. The diameter of the cage between the third movable rubber ring 2-3 and the concrete frame 5 decreases from bottom to top. The bottom diameter of the cage matches the concrete frame 5, and the top diameter matches the third movable rubber ring 2-3. The third cage 4-3 serves to connect the floating system to the concrete frame 5, and can provide a certain buffer when the floating system moves up and down with the waves, preventing the floating system from rising and falling too quickly, thereby improving safety.

[0026] The movable rubber ring is hub-shaped with several hollow areas in the ring direction. The cages are arranged in the hollow areas of the movable rubber ring. The movable rubber ring, the outer support beam 3-1 of the rubber ring and the inner support beam 3-2 of the rubber ring are all hollow structures. All cages are vertically connected inside and are used for fish farming.

[0027] The concrete frame 5 is prefabricated in the factory, and the top is evenly arranged and reserved for lifting rings and cage connection rings. The lifting ring is set on the outside of the cage connection ring to avoid affecting the lifting after the net is complete; a lifting ring is reserved at the intersection of the first movable rubber ring 2-1 and the outer support beam 3-1 of the rubber ring. After the upper movable rubber ring structure is prefabricated, the net is hung on it to form the first cage 4-1 and the second cage 4-2, and further connected with the cage connection ring reserved on the concrete frame 5 to form the third cage 4-3. After the entire movable maintenance ship is berthed and the cage aquaculture system is formed as a whole, according to the lifting ring reserved on the top of the first movable rubber ring 2-1 and the lifting ring reserved on the top of the concrete frame 5, the lifting rope is installed for lifting, wherein the lifting rope connected to the lifting ring reserved on the top of the concrete frame 5 needs to be set as a length-adjustable lifting rope. After the first movable rubber ring 2-1 is installed in place, the lifting rope connected to the lifting ring reserved on the top of the concrete frame 5 is adjusted at a uniform speed, so that the concrete frame 5 sinks in place at a uniform speed.
