Description

Technical Field

[0001] This utility model relates to the field of offshore wind farm engineering development, specifically to a high-pile foundation with marine fishery cages. Background Technology

[0002] According to the offshore wind power industry forecast report, global offshore wind power installed capacity will continue to grow, with China and Europe continuing to occupy an important position in the global new offshore wind power installed capacity. The global new installed capacity will reach 25.4GW in 2025 and 50.9GW in 2030. The report also calls for accelerating the development of offshore wind power clusters and promoting the development and construction of offshore wind power bases with a capacity of tens of millions of kilowatts. The key base clusters include five major offshore wind power base clusters in Shandong Peninsula, Yangtze River Delta, Southern Fujian, Eastern Guangdong, and Beibu Gulf, with Guangdong, Fujian, Zhejiang, Jiangsu, and Shandong provinces serving as key construction bases.

[0003] According to forecasts, coastal provinces and cities have planned nearly 200GW of offshore wind power, with a cumulative grid-connected capacity exceeding 60GW by 2025. As the development of offshore wind farms in my country continues, how to deeply explore the benefits of marine energy within the vast sea areas of wind farms, optimize the industrial structure, and promote the comprehensive development of marine fisheries, clean energy, and marine exploration resources is an important issue worthy of in-depth consideration and exploration.

[0004] Meanwhile, for megawatt-class nearshore and deep-sea large, medium and small offshore wind farms, they not only have tens or even hundreds of square kilometers of sea area, but can also provide a continuous source of clean energy through their own power generation; how to efficiently and intensively use sea resources, enhance the secondary benefits of offshore wind farms, and realize the diversified benefits of nearshore and deep-sea large, medium and small offshore wind farms can promote the joint development model of marine strategic development and comprehensive marine resource development.

[0019] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-2As shown, a high-pile platform for marine fishery cages includes multiple foundation piles 1 and a concrete platform 2. The foundation piles 1 are provided with the concrete platform 2, and the concrete platform 2 is provided with wind power equipment. Multiple cages 4 are suspended around the concrete platform 2 to form a floating and stable structure. Multiple photovoltaic panels 5 are also provided on the concrete platform 2.

[0021] A crane 6 is installed on the concrete foundation 2 near the foundation pile 1. The crane 6 is installed and fixed by a support embedded in the foundation concrete surface of the concrete foundation 2. The range of its boom and lifting capacity can be adjusted according to the size and number of gabion cages 4, and it can rotate 360°. The number of cranes can be adapted according to the number of foundation piles 1 to ensure that a crane 6 is installed on the top of each foundation pile 1 where a gabion cage 4 is installed, for subsequent lifting of the longitudinal gabion cage 4. The foundation pile 1 for which the climbing device 7 is installed does not need to be installed on the top surface of the concrete foundation 2.

[0022] A climbing device 7 is provided between the concrete foundation 2 and at least one foundation pile 1. The arrangement of the gabion 4 should avoid the location of the foundation climbing device 7 to prevent it from being unable to be hoisted.

[0023] To facilitate the berthing of the wind farm maintenance vessel, the climbing device 7 is installed on one of the foundation piles 1 during the wind turbine foundation construction. Therefore, the corresponding position does not require the installation of lifting rings 3, net cages 4, cranes 6, or lifting lines 8. After the vessel is berthed, maintenance personnel can reach the top surface of the concrete foundation 2 via the climbing device 7, and then use the crane 6 to lift the net cages 4 for tasks such as releasing fish fry, feeding, and harvesting. Specifically, the climbing device 7 can be a vertical ladder, a spiral ladder, or a combination of both.

[0024] The cage 4 is composed of supporting steel pipes 41 and netting 42. The supporting steel pipes 41 are welded to form a multi-layered box-like frame of the cage 4 from top to bottom. The netting 42 wraps the frame composed of supporting steel pipes 41. The concrete foundation 2 is provided with lifting rings 3 at the corresponding positions of each foundation pile 1. The lifting rings 3 are pre-embedded in the designated positions of the concrete foundation 2 and can be used to fix the cage 4 after the foundation concrete is poured. The lifting rings 3 are used to hang the suspension line 8 of the cage 4. The cage 4 leans against the foundation pile 1.

[0025] The photovoltaic panel 5 is fixed to the concrete foundation 2 by the photovoltaic bracket 9. The photovoltaic bracket 9 is embedded in the designated position of the concrete foundation 2 and reliably connected to the internal steel bars of the concrete foundation 2. After the foundation concrete is poured, it can be used to install and fix the photovoltaic panel 5. The capacity, layout range and wiring of the photovoltaic panel 5 can be determined according to the reserved space on the upper surface of the concrete foundation 2, the setting of the power transmission and transformation system and the capacity of the wind turbine equipment.

[0026] The above specific embodiments are used to explain and illustrate the present utility model, and are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made to the present utility model within the spirit and protection scope of the claims shall fall within the protection scope of the present utility model.
