The periphery of the support foundation 2 is provided with a berthing device for ships to dock. The converter station platform 1 is fixedly set on the top of the support foundation 2 and is the main structure of the offshore wind power converter station comprehensive utilization platform. The photovoltaic panel assembly 3 and the tower base platform 4 are both fixedly set on the top of the converter station platform 1. The photovoltaic panel assembly 3 is used to absorb solar energy for power generation. The tower base platform 4 is provided with a detection sensor for monitoring marine activities.

[0028] The fish farming box 5 is fixedly assembled on the supporting foundation 2. In this embodiment, the fish farming box 5 is fixedly connected to the supporting foundation 2 by bolts and nuts. While the offshore wind power converter station comprehensively utilizes the platform to transmit current, the fish farming box 5 can also be used for aquaculture, thereby improving the utilization efficiency of the platform.

[0029] The photovoltaic panel assembly 3 is arranged on the top of the converter station platform 1, which can efficiently utilize the offshore solar energy resources. The photovoltaic panel assembly 3 is electrically connected to the solar energy storage device 6, and the solar energy obtained by utilizing the photovoltaic panel assembly 3 is stored in the solar energy storage device 6, which is used as a backup power supply for the offshore wind power flexible direct current converter station platform 1. The solar energy storage device 6 is arranged in the top cabin of the converter station platform 1, which can reduce the distance between the photovoltaic panel assembly 3 and the solar energy storage device 6, facilitate timely collection of solar energy, and also reduce equipment costs. The wind power conversion system 8 is arranged in the top cabin of the converter station platform 1, which is convenient for connecting to the wind turbine on the outer layer of the converter station platform 1 for current conversion.

[0030] The tower base platform 4 is a multi-layered three-dimensional tower base structure for the ocean. The tower base platform 4 is arranged on the top floor of the converter station platform 1, so that the detection sensors on the tower base platform 4 can monitor ocean activities. The tower base platform 4 is connected to the tower base monitoring cabin 7 by signal, and the tower base monitoring cabin 7 is located in the middle cabin of the converter station platform 1. The equipment in the tower base monitoring cabin 7 is used to carry out real-time structural health monitoring of the observation platform, which can provide comprehensive, accurate and real-time ocean big data services for my country's ocean climate evolution research, marine disaster warning and forecasting, and marine economic development. Therefore, some of the instruments needed for monitoring the tower base platform 4 are relatively expensive, so they are placed in the middle of the converter station platform 1 to avoid damage to the equipment caused by extreme weather at sea.

[0031] The offshore wind power converter station comprehensive utilization platform is provided with a photovoltaic panel assembly 3 and a tower base platform 4 on the converter station platform 1, a fish breeding box 5 is installed on the supporting foundation 2, and a solar energy storage device 6, a tower base monitoring cabin 7 and a wind power converter system 8 are simultaneously provided in the converter station platform 1. The photovoltaic panel assembly 3 can generate electricity through solar energy and store the electric energy in the solar energy storage device 6 as a backup power supply for the converter station platform 1; the tower base platform 4 can carry out real-time structural health monitoring of the observation platform through the detection sensors thereon, and provide comprehensive, accurate and real-time marine big data services for marine activities; the fish breeding box 5 can realize aquaculture and provide food reserves for marine operations; the offshore wind power converter station comprehensive utilization platform integrates offshore photovoltaic, marine detection, aquaculture and other operations, improves the efficiency of intensive sea use, reduces the equipment electricity cost and marine development cost, and improves the comprehensive energy field income.

[0032] Preferably, the supporting foundation 2 deviates from the center of the converter station platform 1 in the horizontal direction, and the bottom of the converter station platform 1 deviates from one side of the supporting foundation 2 to form a berthing space.

[0033] The supporting foundation 2 is eccentrically designed relative to the converter station platform 1. The supporting foundation 2 is located on one side of the converter station platform 1 as a whole. The berthing space below the converter station platform 1 that is away from the supporting foundation 2 cooperates with the berthing device outside the supporting foundation 2 to berth ships for the transportation and replenishment of materials, which is convenient to use.

[0034] Preferably, a suction cylinder foundation 9 is further provided in the converter station platform 1 , and a transport channel 10 is provided on the side of the bottom of the converter station platform 1 that deviates from the supporting foundation 2 , and the suction cylinder foundation 9 is arranged on the upper side of the transport channel 10 .

[0035] A suction cylinder foundation 9 is set in the converter station platform 1. When the support foundation 2 is damaged by extreme weather or the support foundation 2 reaches its design life and needs to be replaced, the suction cylinder foundation 9 can be lifted by a crane, and the transportation channel 10 is opened. The suction cylinder foundation 9 slowly passes through the transportation channel 10 with the help of the crane, and the suction cylinder foundation 9 partially sinks to the riverbed by its own weight to serve as a spare support foundation 2. After the replacement of the support foundation 2 is completed, the suction cylinder foundation 9 can be lifted by the crane again, passed through the transportation channel 10 that is opened again, and finally retracted into the converter station platform 1 for the next use.

[0036] In this embodiment, the outside of the suction cylinder foundation 9 is equipped with a water inlet and outlet 11 and an air inlet and outlet 12, and the interior of the suction cylinder foundation 9 is equipped with an air bag, and the suction cylinder is completely sunk into the riverbed by operations such as filling with water and inflating; when the suction cylinder foundation 9 is recovered, the suction cylinder foundation 9 can be separated from the riverbed by operations such as deflating and pumping out water.

[0037] Preferably, a chute 13 and a top platform 14 are provided on the top of the converter station platform 1 , a pulley 15 is provided at the bottom of the top platform 14 , the pulley 15 is guide-assembled with the chute 13 , and a suction cylinder foundation 9 is provided at the bottom of the top platform 14 .

[0038] The top platform 14 can move in the chute 13 through the pulley 15 to open or close the converter station platform 1. When encountering extreme weather at sea, the top platform 14 can be extended through the chute 13 to improve the platform's ability to resist risks. In this embodiment, the top platform 14 includes a plurality of relatively movable top plates 141, each of which has a height difference. The relative movement between each top plate 141 can achieve stacking or unfolding, so that the top platform 14 is a retractable structure.

[0039] The suction cylinder foundation 9 needs to be lowered and recovered by a crane, so the suction cylinder foundation 9 is placed below the retractable top platform 14, which is convenient for the crane to hoist the suction cylinder. When the suction cylinder foundation 9 needs to be hoisted, the top platform 14 can be opened through the chute 13 and the pulley 15 structure.

[0040] Preferably, the supporting foundation 2 includes single-column composite cylindrical foundations 22 arranged in parallel and at intervals, and the fish farming box 5 is fixedly assembled between the single-column composite cylindrical foundations 22 .

[0041] The supporting foundation 2 is formed by a single-column composite cylindrical foundation 22. When the platform encounters extreme weather or other structural components are added to the platform so that its center of gravity and foundation draft change and the structure tilts, the air pressure in different compartments inside the cylinder of the single-column composite cylindrical foundation 22 can be adjusted to maintain the stability of the structure.

[0042] Preferably, it also includes a nozzle 16 which is fixedly mounted at the bottom of the converter station platform 1 . There are multiple nozzles 16 which are arranged around each single-column composite cylindrical foundation 22 . An injection device 17 is provided in the converter station platform 1 , and the injection device 17 is connected to the nozzle 16 .

[0043] A plurality of nozzles 16 are arranged around each single-column composite cylindrical foundation 22, and the jet device 17 can deliver high-pressure gas to the nozzle 16. The high-pressure gas ejected from the nozzle 16 can clean the oysters attached to the single-column composite cylindrical foundation 22, reduce the impact of marine organisms on the service life of the structure, and improve the corrosion resistance of the supporting foundation 2. Under the jet of high-pressure gas, some oysters with relatively fragile shells are crushed and can fall into the fish farming box 5 below as part of the feed for aquaculture. In this embodiment, the jet device 17 is arranged at the bottom layer inside the converter station platform 1 to facilitate the replenishment of high-pressure gas.

[0044] Preferably, the detection sensors include a corrosion sensor 18 , a fiber grating sensor 19 , an acceleration sensor 20 , and an inclinometer 21 .

[0045] Depending on the specific marine environment and the required measurement content, the monitoring sensors can be replaced with different types to achieve different marine data services.

[0046] Preferably, it also includes a hydrogen production device 23, which is arranged in the converter station platform 1 and located at the bottom layer of the converter station platform 1. The bottom of the converter station platform 1 is also provided with a conveying channel 24 for conveying hydrogen storage bottles.

[0047] The hydrogen production device 23 can produce hydrogen by directly electrolyzing seawater samples, and the produced hydrogen is packaged in a hydrogen storage bottle. The hydrogen storage bottle is placed on a ship moored under the platform through a transmission channel 24 at the bottom of the flexible direct current converter station to complete the preparation and transportation of hydrogen.

[0048] The production of hydrogen requires a large amount of seawater as a raw material, which is heavy. Placing the hydrogen production device 23 on the bottom layer of the converter station platform 1 can obtain seawater more quickly and reduce transportation time and transportation costs.

[0049] Preferably, the converter station platform 1 is further provided with connecting screw holes 25 , and the connecting screw holes 25 are provided on the top of the converter station platform 1 and the side wall of the converter station platform 1 .

[0050] By connecting the screw holes 25, the converter station platform 1 can be overlapped with the through holes opened in other offshore structures and fixed with bolts. For example, the left and right sides of the converter station can be connected to the booster station. When a structure fails, it can also be connected to a temporary maintenance platform, thereby improving the comprehensive utilization capacity and risk resistance of the platform.
