Description

Wind tower device for large-capacity floating wind turbine and method for constructing a wind turbine using the same

[0001] The present invention relates to a wind tower device for a large-capacity floating wind power generator and a method for constructing a wind power generator using the same, and more specifically, to a wind tower device for a large-capacity floating wind power generator and a method for constructing a wind power generator using the same, which enable installation and maintenance of a wind power generator to be performed on a floating body itself through rails and a transfer plate provided to enable raising and lowering between a plurality of towers, thereby enabling easier work, and minimizing costs associated with construction and maintenance of the wind power generator.

[0002] Wind turbines are devices installed on land or at sea that convert wind energy into electrical energy and generate electricity. Due to growing concerns about environmental regulations stemming from global warming and the instability of fossil fuel supply, wind power is gaining traction as a renewable energy production system.

[0003] Wind power plants have been primarily installed on land, but offshore installations are gradually increasing. Offshore wind power generally offers better wind quality than onshore, and blade noise issues can be more easily addressed. To ensure economic viability, large-scale wind farms are essential. However, these are difficult to build on land, making coastal and offshore locations increasingly attractive as large-scale offshore wind farms.

[0004] Structures for offshore wind power installations can be broadly categorized into fixed and floating types. Fixed structures, like those on land, are directly anchored to the seabed and respond to environmental loads through structural deformation. Floating structures float on the water surface, subject to their own weight, buoyancy, environmental loads, and mooring forces, and overcome environmental loads through the structure's degrees of freedom of motion.

[0005] Until recently, offshore wind turbines were primarily installed in shallow waters, often as fixed structures. While fixed structures offer favorable operating conditions due to their anchorage to the seabed, deeper waters often lead to excessively large structures, increasing the risk of fatigue failure. Furthermore, the trend toward larger wind turbines has led to astronomical increases in the costs of building and installing these structures.

[0006] Furthermore, winds become stronger and more consistent the farther from land they are, which can increase power generation efficiency. Consequently, the need for wind power development in deeper waters further from the coast is increasing. Consequently, extensive research is being conducted on floating wind power plants that are not limited by structure size, even in deeper waters.

[0007] Floating offshore wind power generation facilities typically include a tower, a generator body, and blades. Each of these components is manufactured on land and transported to the sea, where assembly and installation work is performed together at sea. Alternatively, all assembly work of the offshore wind power generator is performed on land, then transported to the sea, where only the installation work is performed at sea.

[0008] However, if offshore wind turbines are assembled on land and then transported to the sea for installation, their large size and complex exterior make it difficult to load a large number of them onto the installation vessel, thereby reducing transport efficiency. In particular, if assembled offshore wind turbines are loaded onto the installation vessel and transported in an upright state, the air resistance generated during operation can put a strain on the turbine blades, potentially leading to turbine failure.

[0009] Therefore, recently, a method has been used in which each component is transported by sea and assembly and installation work are performed together. However, this method also requires the assembly and installation work to be performed sequentially, which prolongs the process period and requires a lot of manpower. In particular, there are problems in that the efficiency of the work is reduced due to the complexity of the structure of the offshore wind turbine installation ship.

[0010] As an example of a conventional method of installing offshore wind turbines, a technology described in Korean Patent No. 10-1304912 was proposed. The technology described therein has the advantage of allowing easy installation by assembling the wind turbine on a ship and opening the diaphragm while filling it with seawater to move the wind turbine. However, this has the problem that, as floating offshore wind turbines become larger, larger cranes or ships dedicated to installing wind turbines are inevitably required, and as a result, installation and construction costs also increase exponentially.

[0011] The present invention was created to solve the above-described problem, and more specifically, it is intended to provide a wind tower device for a large-capacity floating wind turbine, which enables installation and maintenance of a wind turbine on a floating body itself through rails and a transfer plate that are provided to be able to be raised and lowered between a plurality of towers, thereby enabling easier work, and minimizing the cost of construction and maintenance of the wind turbine, and a wind turbine construction method using the same.

[0016] More specifically, the wind turbine comprises a plate-shaped support, and the wind turbine loading step comprises a support joining step of joining the support to the upper part of a transfer plate at the lower part of the tower; a turbine loading step of loading a turbine of the wind turbine onto the upper part of the support; and a blade installation step of installing a blade of the wind turbine on one surface of the turbine.

[0017] More specifically, the turbine loading step is characterized in that the turbine is loaded between a plurality of the towers so as to be perpendicular to the longitudinal direction of the towers.

[0018] More specifically, the blade installation step is characterized in that it is performed after the transfer plate is elevated from the bottom of the tower to the longitudinal center.

[0019] More specifically, the wind turbine comprises a plate-shaped support, and the wind turbine installation step is characterized in that the support is fastened to the top of a tower so that the support interconnects the towers between the tops of a plurality of the towers.

[0020] More specifically, the wind turbine construction method is characterized in that, after the wind turbine installation step, the transfer plate is separated from the support and lowered toward the bottom of the tower.

[0021] A wind tower device for a large-capacity floating wind power generator according to one embodiment of the present invention enables installation and maintenance of the wind power generator on the floating body itself through rails and transfer plates that are provided to be able to be raised and lowered between a plurality of towers, thereby enabling easier work and providing the effect of minimizing costs associated with construction and maintenance of the wind power generator.

[0022] In particular, a large-capacity floating wind turbine according to one embodiment of the present invention includes a plurality of towers and jacking equipment that are fixed to the upper center of a floating body at a predetermined distance from each other, so that installation and maintenance of the wind turbine can be performed on the floating body itself by raising and lowering a transfer plate provided between the plurality of towers, thereby eliminating the need for a large offshore crane or maintenance crane, which are essentially required in the construction method of a conventional floating wind turbine, thereby providing the effect of reducing the cost and time required for constructing a floating wind turbine.

[0025] In addition, a method for constructing a wind power generator using a wind tower device for a large-capacity floating wind power generator according to an embodiment of the present invention includes a blade installation step performed at the center of the longitudinal direction of the tower, so that unlike a conventional construction method in which the operation of the blade is checked after installing the blade at the top of the wind power tower and, if a defect exists, the blade must be removed and transported again or the entire wind power generator must be disassembled, once the operation of the blade is checked at the center of the tower, the wind power generator can be elevated to the top of the tower to proceed with the final installation, thereby providing the effect of providing improved work efficiency in the construction of a wind power generator.

[0042] First, a wind tower device for a large-capacity floating wind turbine according to one embodiment of the present invention will be described with reference to FIGS. 1 to 3.

[0045] First, the floating body (100) is provided to support a structure installed on top while floating on the sea.

[0046] More specifically, the floating body (100) may be provided in the form of a structure extending radially from the center as shown in FIGS. 1 and 3, but is not limited thereto and may be configured to have a structure capable of stably floating on the sea.

[0047] Next, the tower (200) is characterized in that it has a column shape of a predetermined length and is provided in multiple units, as shown in FIGS. 1 to 3.

[0049] More specifically, the tower (200) may have a shape in which one side of the upper part of the pillar is cut at a predetermined angle, as shown in FIGS. 1 and 2.

[0050] Accordingly, by structurally overlapping the pillar and blade (310) of the tower (200) through the shape of the tower (200), thereby preventing the wind from being blocked, the wind can be more easily transmitted onto the blade (310) of the wind turbine (300), thereby providing the effect of providing more improved power generation efficiency.

[0051] In addition, the wind tower device for a large-capacity floating wind turbine of the present invention provides the effect of stably supporting the wind turbine while floating stably on the sea, compared to the structure of a conventional floating wind turbine, by supporting the wind turbine through a plurality of towers (200).

[0061] First, the rails (410) are characterized in that they are formed along the length direction from the bottom to the top of the tower (200) on the sides of the plurality of towers (200).

[0062] In addition, the above-mentioned transfer plate (420) has a plate shape and is fastened to the rail (410) to transport an object while moving up and down along the rail (410) between a plurality of the above-mentioned towers (200).

[0063] More specifically, the rail (410) may be formed on both sides of the tower (200), that is, on the front and rear sides with reference to FIG. 2, so that the transfer plate (420) can be more stably fastened, thereby allowing it to be more stably raised and lowered on the rail (410).

[0064] In addition, the above jacking equipment (400) is provided to transport the wind turbine or various maintenance equipment by loading it on the upper part of the transfer plate (420) during installation and maintenance of the wind turbine (300).

[0065] In addition, the jacking equipment (400) is characterized in that it is provided so that a worker can perform installation and maintenance work of the wind turbine (300) from the upper part of the transfer plate (420).

[0066] More specifically, the jacking equipment (400) is characterized in that, when installing the wind turbine (300), it loads the wind turbine on the upper part of the transfer plate (420) and transports it to the upper part of the tower (200), and, when maintaining the wind turbine (300), it loads various maintenance equipment on the upper part of the transfer plate (420) and transports it to the location of the wind turbine (300).

[0067] As described above, the wind tower device for a large-capacity floating wind power generator of the present invention includes a plurality of towers (200) and a jacking device (400) that are fixed to the upper center of a floating body at a predetermined distance from each other, so that the wind power generator can be installed and maintained on the floating body itself by raising and lowering a transfer plate provided between the plurality of towers, thereby providing the effect of reducing the cost and time for constructing a floating wind power generator by not using a large offshore crane and a maintenance crane, which are essentially required in the construction method of a conventional floating wind power generator.

[0068]

[0069] Next, a method for constructing a wind power generator using a wind tower device for a large-capacity floating wind power generator according to one embodiment of the present invention will be described with reference to FIGS. 4 to 13.

[0070] FIG. 4 is a block flowchart illustrating the progress sequence of a wind power generator construction method using a wind tower device for a large-capacity floating wind power generator according to one embodiment of the present invention, FIG. 5 is a drawing illustrating an example of a state in which a floating body mooring step has been performed, FIG. 6 is a drawing illustrating an example of a state in which a tower installation step has been performed, and FIG. 7 is a drawing illustrating an example of a state in which a transfer plate fastening step has been performed.

[0071] And, Fig. 8 is a block flow diagram schematically illustrating the progress sequence of the wind turbine loading step, Fig. 9 is a drawing illustrating an example of a state in which the support bonding step has been progressed, Fig. 10 is a drawing illustrating an example of a state in which the turbine loading step has been progressed, and Fig. 11 is a drawing illustrating an example of a state in which the blade installation step has been progressed.

[0072] In addition, Fig. 12 is a drawing showing an example of a state in which the wind turbine installation step has been completed, and Fig. 13 is a drawing showing an example of a state in which the transfer plate has been lowered after the wind turbine installation step.

[0073] First, the method for constructing a wind power generator using a wind tower device for a large-capacity floating wind power generator of the present invention corresponds to a method for constructing a large-capacity floating wind power generator using a wind tower device including a floating body, a plurality of towers, and a jacking device having a rail and a transfer plate formed along the longitudinal direction of the tower on the side of the tower.

[0074] As illustrated in FIG. 4, a method for constructing a wind power generator using a wind tower device for a large-capacity floating wind power generator of the present invention (S1000) includes a floating body mooring step (S100), a tower installation step (S200), a transfer plate fastening step (S300), a wind power generator loading step (S400), and a wind power generator installation step (S500).

[0075] First, the floating body mooring step (S100) is performed to moor the floating body (100) at sea, as shown in FIG. 5.

[0076] And, the tower installation step (S200) is performed by arranging a plurality of towers (200) at a predetermined distance from each other at the upper center of the floating body (100), as shown in FIG. 6.

[0077] Next, the transfer plate fastening step (S300) is performed by positioning the transfer plate (420) between a plurality of the towers (200) and fastening it to the rail (410), as shown in FIG. 7.

[0078] In addition, the wind turbine loading step (S400) is performed to load the wind turbine on top of the transfer plate.

[0079] Here, the wind turbine is characterized by including a plate-shaped support.

[0080] More specifically, the wind turbine loading step (S400) includes a support bonding step (S410), a turbine loading step (S420), and a blade installation step (S430), as illustrated in FIG. 8.

[0081] First, the support bonding step (S410) is performed to bond the support (330) to the upper portion of the transfer plate (420) at the lower portion of the tower (200), as illustrated in FIG. 9.

[0082] And, the turbine loading step (S420) is performed to load the turbine (320) of the wind power generator on top of the support (330), as shown in FIG. 10.

[0083] Here, in the turbine loading step (S420), the turbine (320) is characterized in that it is loaded between a plurality of towers (200) so as to be perpendicular to the length direction of the tower (200).

[0084] More specifically, the turbine loading step (S420) is performed by loading and installing the turbine on a support in advance in the same direction as the turbine's installation direction when the wind power generator is operated so that the blade can be easily installed on the turbine in the blade installation step (S430) described later.

[0085] Accordingly, the wind power generator construction method using a wind tower device for a large-capacity floating wind power generator of the present invention can install the turbine by loading it on a support at the bottom of the tower and doing so at the same time, unlike the conventional floating wind power generator construction method that requires a separate installation work after transporting the turbine by lifting it, and thus has the effect of providing improved work efficiency in the construction of the wind power generator.

[0086] Next, the blade installation step (S430) is performed to install the blade (310) of the wind turbine on one side of the turbine (320), as illustrated in FIG. 11.

[0087] More specifically, the blade installation step (S430) is characterized in that it is performed after the transfer plate (420) is elevated from the bottom of the tower (200) to the longitudinal center.

[0088] Accordingly, the method for constructing a wind power generator using a wind tower device for a large-capacity floating wind power generator of the present invention includes a blade installation step (S430) performed at the center of the longitudinal direction of the tower, so that unlike the conventional construction method in which the operation of the blade is checked after installing the blade on the top of the wind power tower and the blade must be removed and transported again or the entire wind power generator must be disassembled if a defect exists, once the operation of the blade is checked at the center of the tower, the wind power generator can be elevated to the top of the tower to proceed with the final installation, thereby providing the effect of providing improved work efficiency in the construction of the wind power generator.

[0089] Next, the wind power generator installation step (S500) is performed by lifting the transfer plate (420) to the upper part of the tower (200) as shown in FIG. 12 to install the wind power generator (300) on the top of the tower (200).

[0090] Here, parts, tools, equipment, etc. for construction of a wind turbine (300) can be loaded and transported together in the space between the transfer plate (420) and the support (330).

[0091] And, the above wind power generator installation step (S500) is characterized in that the support (330) is fastened and fixed to the top of the tower (200) so that the support (330) interconnects the towers (200) between the tops of the plurality of towers (200).

[0092] More specifically, when fixing the support (330) to the top of the tower (200), the support (330) is firmly fixed to the tower (200) using a separate fastening member such as a bolt.

[0093] As described above, the method for constructing a wind power generator using a wind tower device for a large-capacity floating wind power generator of the present invention includes a tower installation step (S200) and a wind power generator installation step (S500), so that the wind power generator can be installed on the top of the tower by loading the wind power generator on a transfer plate between a plurality of towers and raising and lowering the transfer plate, thereby enabling the installation of the wind power generator on the floating body itself, thereby providing the effect of reducing the cost and time for constructing the floating wind power generator by not using a large offshore crane and a maintenance crane, which are essentially required in the construction method of a conventional floating wind power generator.

[0094] In addition, the method for constructing a wind power generator using a wind tower device for a large-capacity floating wind power generator of the present invention includes a wind power generator installation step (S500) of fastening and fixing a support to the top of a tower, so that the support can stably fix and support the blades and turbines of the wind power generator on the tops of multiple towers, thereby further improving the structural stability between the wind power generator and the wind power tower, and providing the effect of enabling stable operation of the large-capacity floating wind power generator.

[0095] Next, the method for constructing a wind power generator using a wind tower device for a large-capacity floating wind power generator of the present invention proceeds by, as illustrated in FIG. 13, separating the transfer plate (420) from the support (330) and lowering it toward the lower part of the tower (200) after the wind power generator installation step (S500) described above.

[0096] Accordingly, the method for constructing a wind power generator using a wind tower device for a large-capacity floating wind power generator of the present invention can provide the effect of enabling maintenance of a wind power generator to be easily performed without using a separate large offshore crane or maintenance crane for maintenance of the wind power generator by loading various equipment for maintenance on a transfer plate at the bottom of the tower when maintenance of the wind power generator is required after installation and construction of the wind power generator and allowing workers to climb on the transfer plate and ascend to a position requiring maintenance of the wind power generator to perform the work.

[0097]

[0098] Although the present invention has been described above with specific details such as specific components and limited examples and drawings, these are provided only to help a more general understanding of the present invention, and the present invention is not limited to the above examples, and those with ordinary knowledge in the technical field to which the present invention pertains can make various modifications and variations from this description.
