图1是本申请一实施例提出的一种半潜式漂浮式风机装置的结构示意图。Fig. 1 is a schematic structural diagram of a semi-submersible floating fan device proposed by an embodiment of the present application.
目前近海风电场所采用的各种类型的固定式基础的自重和工程造价随着水深增大而大幅度增加，具体来说：(1)单桩基础：结构较柔，自振频率过低，容易发生共振，只能通过增加钢管桩和混凝土的工程量来提高风机基础的刚度，经济性较差；(2)高桩承台基础：由于深远海离岸较远，海上作业时间较长，经济性较差；(3)重力式基础：由于体积大，重量重，工程造价较高，若采用空腔结构，还要考虑水压影响，经济性较差；(4)导管架基础：随着水深增加，管节点疲劳设计复杂、安全风险大，且结构重量也快速增加，制造加工成本高。因此，采用浮式风电基础是解决这一问题的最佳选择。深海中浮式风机基础的主要优点包括：除系泊***需要微调外，海上浮式风机基础在深海中可保持结构不变，不会随水深增加结构重量；浮式风机基础安装成本较低，具有更广阔的市场前景。此外，由于地质复杂，固定式基础在每个机位都需要进行定制化设计，难以实现标准化，制造加工及施工成本明显增加；而浮式风机基础成本较固定式基础小，且不受水深及地质影响，可实现批量标准化，节省制造加工和安装成本。此外，浮式风机可以布置在更开阔的海域以获 取更丰富的风能，避免了视觉冲击和噪声污染，还有利于孤立岛屿的开发。因此，未来风电场的建设必然是“由陆向海、由浅到深、由固定式向浮动式”的趋势。At present, the self-weight and engineering cost of various types of fixed foundations used in offshore wind farms increase greatly with the increase of water depth. Specifically: (1) Single pile foundation: the structure is relatively soft, the natural frequency is too low, and If resonance occurs, the rigidity of the wind turbine foundation can only be increased by increasing the amount of steel pipe piles and concrete, which is less economical; (2) High pile cap foundation: because the deep sea is far away from the shore, the offshore operation time is longer, The economy is poor; (3) Gravity foundation: Due to the large volume and weight, the project cost is high. If the cavity structure is adopted, the influence of water pressure must also be considered, so the economy is poor; As the water depth increases, the fatigue design of the pipe joints is complicated, the safety risk is large, and the structural weight also increases rapidly, resulting in high manufacturing and processing costs. Therefore, the use of floating wind power foundation is the best choice to solve this problem. The main advantages of the floating wind turbine foundation in the deep sea include: except for the mooring system that needs to be fine-tuned, the offshore floating wind turbine foundation can maintain the same structure in the deep sea, and the structural weight will not increase with the water depth; the installation cost of the floating wind turbine foundation is low, Has a broader market prospect. In addition, due to the complex geology, the fixed foundation needs to be customized for each machine position, which is difficult to achieve standardization, and the manufacturing, processing and construction costs increase significantly; while the foundation cost of the floating wind turbine is lower than that of the fixed foundation, and it is not affected by water depth and Geological influence, batch standardization can be realized, and manufacturing processing and installation costs can be saved. In addition, floating wind turbines can be arranged in more open sea areas to obtain more abundant wind energy, avoid visual impact and noise pollution, and are also conducive to the development of isolated islands. Therefore, the construction of wind farms in the future must be a trend of "from land to sea, from shallow to deep, from fixed to floating".

Specifically, the buoyancy and gravity distribution of the resultant force is formed by adjusting the ballast degree of each buoy to maintain the balance of the fan unit. The towers are detachably connected by bolts, multiple anchor foundations are arranged around each buoy, and the anchor foundations are fixedly connected to the buoys through mooring cables to fix the position of the buoys, with good stability and convenient installation.
参见图1，一种半潜式漂浮式风机装置还包括多个桁架6，相邻的两所述浮筒1之间通过所述桁架6固定连接，加强多个浮筒之间连接的稳固性，形成稳定的分布式结构，便于对风机进行支撑。桁架包括横撑与斜撑，通过横撑与斜撑共同以多个角度实现相邻浮筒的连接，可以保证整个风机装置有更强的连接稳定性。所述横撑与所述斜撑均为钢制管道。具体的，横撑与斜撑均可以为钢管，以此相较于钢柱，可以节约钢材，且可以起到稳定连接的要求。Referring to Fig. 1, a semi-submersible floating fan device also includes a plurality of trusses 6, and two adjacent buoys 1 are fixedly connected through the trusses 6 to strengthen the stability of the connection between a plurality of buoys, forming Stable distributed structure, easy to support the fan. The truss includes cross braces and diagonal braces, and through the cross braces and diagonal braces, the connection of adjacent buoys can be realized at multiple angles, which can ensure stronger connection stability of the entire fan unit. Both the cross brace and the diagonal brace are steel pipes. Specifically, both the cross brace and the diagonal brace can be steel pipes, so that compared with steel columns, steel materials can be saved, and the requirements for stable connection can be met.
所述浮筒1为三个，三个所述浮筒1的连线形成正三角形，如图1所示，浮筒1的数量可以为3个，以此结合桁架2连接这三个浮筒1，可以实现三角稳定，在保证足够的稳定性以及强度的同时，还能最大程度节约材料，最终降低成本。There are three buoys 1, and the connecting lines of the three buoys 1 form an equilateral triangle. As shown in Figure 1, the number of buoys 1 can be three, and the three buoys 1 can be connected in combination with the truss 2 to realize The triangle is stable, while ensuring sufficient stability and strength, it can also save materials to the greatest extent and ultimately reduce costs.
所述锚固基础4为三个，三个所述锚固基础4分别对应设置在三个所述浮筒1的外侧，三个锚固基础的连线也形成正三角形，各个浮筒外侧分别固定连接锚固基础，在整体对风机装置进行固定的同时，也能够避免单一系泊缆断裂造成风机漂移的情况发生。There are three anchoring foundations 4, and the three anchoring foundations 4 are respectively arranged on the outsides of the three buoys 1. The connecting lines of the three anchoring foundations also form an equilateral triangle, and the outer sides of each buoy are respectively fixedly connected to the anchoring foundations. While fixing the wind turbine device as a whole, it is also possible to avoid the drift of the wind turbine caused by the breakage of a single mooring cable.
所述浮筒1为中空的柱状结构，具有较好的浮力，能够承载风机立于海面之上。The buoy 1 is a hollow columnar structure with good buoyancy and can carry a wind turbine to stand on the sea surface.
参见图2和图4，所述锚固基础4包括锚固基础主体41和设置于所述锚固基础主体41上的至少一个系泊缆柱头42，所述锚固基础主体41沉入泥面，所述系泊缆柱头42通过系泊缆5和所述浮筒1连接。其系泊缆柱头的数量可以为2个、4个或其他数量。一般建议多留1-2个柱头，以降低在施工安装时，系泊缆与柱头方向间可连接的难度；还可在柱头由于腐蚀、长期服役疲劳损坏、极端工况下极限载荷破坏等造成损坏后，留存可替代的选择。Referring to Fig. 2 and Fig. 4, the anchor foundation 4 includes an anchor foundation main body 41 and at least one mooring cable stud 42 arranged on the anchor foundation main body 41, the anchor foundation main body 41 sinks into the mud surface, and the anchor foundation main body 41 sinks into the mud surface. The mooring line stud 42 is connected to the buoy 1 through the mooring line 5 . The quantity of its mooring bitt heads can be 2, 4 or other quantities. It is generally recommended to leave 1-2 more column heads to reduce the difficulty of connecting the mooring line with the direction of the column heads during construction and installation; the column heads can also be damaged due to corrosion, long-term service fatigue damage, and extreme load damage under extreme working conditions. After that, save the alternative options.
参见图3，所述系泊缆柱头42上设置有系孔，便于安装连接系泊缆。Referring to FIG. 3 , mooring holes are provided on the mooring line stud head 42 to facilitate the installation and connection of mooring lines.
所述锚固基础4为预应力混凝土柱体，具有较高的结构强度。The anchor foundation 4 is a prestressed concrete column with high structural strength.
一台漂浮式风机的费用主要构成为：风机约占25％，浮式平台约占25％，系泊缆约占12％，锚固基础约占18％，运输安装费用约占20％。固定式风机的基础占比一般在30％左右，而对于漂浮式风机，浮式平台+系泊缆+锚固基础的占比达到了55％。因此，漂浮式风机的降本主要方向就是在系泊缆和锚固基础。在规模化开发的风场中，当漂浮式基础型式确定后，系泊缆的数量是确定的，而锚固基础的数量可以通过相邻风机共同使用来减少数量。在当前的漂浮式风 机中，还没有对规模化开发的排布进行研究以减少锚固基础数量的方案。因此，本申请旨在给出新的半潜式漂浮式风机锚固基础布置方案，以降低规模化开发的漂浮式风场的成本。The cost of a floating wind turbine is mainly composed of: the wind turbine accounts for about 25%, the floating platform accounts for about 25%, the mooring line accounts for about 12%, the anchor foundation accounts for about 18%, and the transportation and installation costs account for about 20%. The foundation of fixed wind turbines generally accounts for about 30%, while for floating wind turbines, the proportion of floating platform + mooring cable + anchor foundation reaches 55%. Therefore, the main direction of cost reduction for floating wind turbines is mooring cables and anchoring foundations. In large-scale development of wind farms, when the type of floating foundation is determined, the number of mooring lines is determined, and the number of anchored foundations can be reduced by sharing the use of adjacent wind turbines. In the current floating wind turbines, there is no research on the arrangement of large-scale development to reduce the number of anchor foundations. Therefore, this application aims to provide a new semi-submersible floating wind turbine anchor foundation layout scheme to reduce the cost of large-scale development of floating wind farms.
参见图7-图10，一种半潜式漂浮式风机***，包括多个所述的风机装置，多个所述风机装置在海面上间隔排列设置。Referring to Figures 7-10, a semi-submersible floating fan system includes a plurality of the above-mentioned fan devices, and the plurality of fan devices are arranged at intervals on the sea surface.

在大规模批量化漂浮式风场的建设中，所述漂浮式风机锚固基础的系泊缆柱头可以用于连接多个风机的系泊缆，应用在本申请给出的漂浮式风机布置方案中，以减少锚固基础的数量。与现有未优化过的传统漂浮式风机设计方案比，本申请所述的新型漂浮式风机锚固基础和排布方案可以有效改善锚固基础水平向受力特性；以30台10MW机组测算，可减少锚固基础数量58％，极大降低漂浮式风场造价；此外，本申请提出的锚固基础结构和布置方案还可减少施工和安装时间，成本较低。In the construction of large-scale batch floating wind farms, the mooring cable stud head of the anchor foundation of the floating wind turbine can be used to connect the mooring cables of multiple wind turbines, which is applied in the layout scheme of the floating wind turbine given in this application , to reduce the number of anchor foundations. Compared with the existing non-optimized traditional floating wind turbine design scheme, the new floating wind turbine anchor foundation and arrangement scheme described in this application can effectively improve the horizontal force characteristics of the anchor foundation; it can reduce the The number of anchoring foundations is 58%, which greatly reduces the cost of floating wind farms; in addition, the anchoring foundation structure and layout scheme proposed in this application can also reduce construction and installation time, and the cost is low.
图5和图6是本申请示出的单台采用新型锚固基础的半潜式漂浮式风机平面布置图，两种形式对称。在不采用本申请提出的共锚固基础节点的方案中，安装2台漂浮式风机需要2×3＝6个锚固基础。在采用了本申请给出的新型锚固基础和半潜式风机平面布置方案后，图8-图15分别给出了4、6、9、12、16、24、30台风机的布置图。下表给出了传统设计与新型设计方案的锚固基础数量 对比和百分比变化。参见图11，可以看到，当风场容量变大，风机数量增加时，采用本申请提出的新型设计减少的锚固基础的数量的百分比也不断增加。全场30台风机时可减少锚固基础数量38个，减少百分比达58％。Figure 5 and Figure 6 are the layout diagrams of a single semi-submersible floating wind turbine using a new type of anchor foundation shown in this application, and the two forms are symmetrical. In the scheme that does not adopt the common anchor foundation node proposed in this application, 2×3=6 anchor foundations are required to install 2 floating wind turbines. After adopting the new-type anchor foundation and the plane layout plan of the semi-submersible wind turbines given in this application, Figures 8-15 show the layouts of 4, 6, 9, 12, 16, 24, and 30 wind turbines respectively. The following table shows the comparison and percentage change of the anchor foundation quantity and percentage change between the traditional design and the new design scheme. Referring to Fig. 11, it can be seen that when the capacity of the wind field increases and the number of wind turbines increases, the percentage of the number of anchorage foundations reduced by the new design proposed by the application also increases continuously. When there are 30 wind turbines in the field, the number of anchor foundations can be reduced by 38, with a reduction percentage of 58%.
