Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind power generation technology, and in particular to a floating wind turbine. Background Technology
[0002] Floating wind power, as an emerging clean energy technology, has shown great potential in deep-sea wind energy development in recent years. A floating wind turbine consists of a floating base and a turbine body. The turbine body is mounted on the floating base, and its core component, the floating base, is connected to its own weight (such as anchor blocks or counterweights) via a chain system. The movement, adjustment, and positioning of the tower are achieved by winding and releasing the chains. This design allows the system to adapt to complex marine environments, but the performance of the chain winding device directly affects the stability of the tower base, its movement efficiency, and overall operational safety.
[0003] In practical applications, uneven chain winding has become one of the main bottlenecks restricting the reliability of floating wind power generation systems. Traditional chain winding devices typically include a take-up roller and a drive mechanism. The take-up roller is used to wind the chain, and the drive mechanism provides power. However, the design of traditional take-up rollers is usually a simple cylindrical structure that rotates only around its own axis. This causes the chain to be over-wound in localized areas of the take-up roller, resulting in too many layers. Because the chain cannot be evenly distributed on the take-up roller, problems such as overlapping, misalignment, or cross-winding easily occur during the winding process.
[0004] Disorganized and intertwined cable stacking not only reduces adjustment efficiency but can also lead to cable wear and even breakage, thereby increasing maintenance costs and system failure risks. Specifically, uneven stress concentration during cable winding accelerates material fatigue and shortens service life. Furthermore, disorganized and intertwined chains can cause jamming during release, further affecting system response speed and positioning accuracy. These problems not only increase maintenance complexity but may also pose safety hazards, such as chain breakage leading to tower base instability under extreme sea conditions. Utility Model Content
[0005] To address the technical problem that existing devices cannot evenly distribute the chain on the take-up drum, leading to chain entanglement and knotting, this invention provides a floating wind turbine generator that can evenly distribute the chain on the take-up drum.
[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] A floating wind turbine includes a floating base, a turbine body, and a chain. The turbine body is mounted on the floating base, which is equipped with a winding device. One end of the chain is connected to the winding device, and the other end is connected to its own weight. The winding device is used for winding and unwinding the chain. The floating base includes a pontoon, and the winding device is located inside the pontoon. The side of the pontoon has a winding port that penetrates the inner and outer walls of the pontoon. The winding device includes a first transmission part, a central rod, a linkage rod, a winding drum, and a reciprocating push mechanism. A drive motor is fixed to the top of the pontoon, and a second transmission part is mounted on the output shaft of the drive motor. The second transmission part is coaxial with the output shaft and can drive the first transmission part to rotate. The central rod is vertically arranged, with the first end of the central rod... The first transmission part is fixedly sleeved on the central rod and can rotate around the central axis of the central rod. The linkage rod is parallel to the central axis of the first transmission part. One end of the linkage rod is fixedly set on the bottom surface of the first transmission part. The top of the take-up drum has a mating hole corresponding to the linkage rod. The other end of the linkage rod passes through the mating hole. The take-up drum can slide along the axial direction of the linkage rod and rotate around the central axis of the first transmission part. The sliding range is limited by the mating length between the linkage rod and the mating hole. The reciprocating push mechanism is fixedly set on the inner wall of the bottom of the float. The output end of the reciprocating push mechanism contacts the bottom of the take-up drum. The reciprocating push mechanism pushes the take-up drum to slide along the linkage rod. The take-up drum returns to its original position by its own gravity.
[0008] Furthermore, the reciprocating push mechanism includes a plate and a telescopic push rod. A limit block is fixedly connected to the bottom of the take-up drum. The plate is located below the limit block, and the upper surface of the plate is in contact with the limit block. A hinged support is provided on the inner wall of the bottom of the float. The bottom of the plate has a connecting part, which is hinged to the hinged support. The telescopic push rod is located on the inner wall of the bottom of the float. The output end of the telescopic push rod is hinged to the bottom surface of the plate. The telescopic push rod pushes the plate to reciprocate around the hinged support at a certain angle, causing the upper surface of the plate to tilt up and down relative to the horizontal plane.
[0009] Furthermore, the plate has a clearance hole in the center, and the second end of the center rod passes through the take-up drum and the plate in sequence, and the second end of the center rod is fixed to the inner wall of the bottom of the float.
[0010] Furthermore, the plate is a round plate.
[0011] Furthermore, there are two linkage rods, which are located on both sides of the central axis of the first transmission part, and the two linkage rods are symmetrically arranged with respect to the central axis of the first transmission part.
[0012] Furthermore, both the first and second transmission parts are gears, and the first and second transmission parts mesh with each other.
[0013] Furthermore, it also includes a spring, with the second end of the center rod passing through the first transmission part, the spring being sleeved on the center rod, one end of the spring abutting against the first transmission part, and the other end of the spring abutting against the take-up roller.
[0014] Furthermore, there are three pontoons arranged in an equilateral triangle, and a connecting rod is also included, with adjacent pontoons connected by the connecting rod.
[0015] Furthermore, the main body of the wind turbine includes a tower and a wind turbine generator set. The bottom of the tower is fixed on a floating base, and the wind turbine generator set is installed on the top of the tower.
[0016] Furthermore, it also includes a fixed base and three support rods. The fixed base is fixed to the bottom of the tower by bolts. The three support rods are distributed in a ring around the central axis of the tower. The included angle between two adjacent support rods is 120°. One end of the support rod is fixedly connected to the fixed base, and the other end of the support rod is fixedly connected to the pontoon.
[0017] The beneficial effects of this utility model are:
[0018] This invention provides a floating wind turbine, with a particular improvement to its winding device to solve the problems of chain entanglement and knotting that occur in traditional winding devices. These problems limit the reliability and efficiency of floating wind power generation systems. This solution introduces a new winding device structure, allowing the winding drum to slide up and down under the action of a reciprocating push mechanism. This ensures that the chain is evenly distributed on the winding drum, effectively preventing knotting and entanglement during winding, improving the flexibility of the winding process, and increasing overall winding efficiency and system stability. This not only allows for more even chain distribution, avoiding material fatigue caused by localized stress concentration and thus extending the chain's service life, but also reduces maintenance frequency and costs, and decreases the risk of failure due to chain breakage.
[0019] In addition, the telescopic push rod drives the plate to swing back and forth, causing the plate to tilt. This results in a periodic change in the height of the contact point between the take-up roller and the plate, which in turn drives the take-up roller to slide along the linkage rod axis. This ensures the smoothness of the winding process and improves the system's response speed and positioning accuracy. This is especially important for maintaining the stability of the floating base and reducing safety hazards.
[0020] In conclusion, this design scheme, through a series of ingenious mechanical design improvements, solves key problems in existing technologies, significantly improves the performance and reliability of floating wind power generation systems, and is of great significance for promoting the development of deep-sea wind energy.

[0030] Reference Figures 1 to 4This utility model provides a floating wind turbine.
[0031] like Figures 1 to 3 As shown, a floating wind turbine includes a floating base, a turbine body, and a chain 1. The turbine body is mounted on the floating base, which is equipped with a winding device. One end of the chain 1 is connected to the winding device, and the other end is connected to a weight 2. The winding device is used for winding and unwinding the chain 1. The floating base includes a float 3, and the winding device is located inside the float 3. The side of the float 3 has a take-up port 4 that penetrates the inner and outer walls of the float 3. The chain 1 is connected to the winding device through the take-up port 4. The winding device includes a first transmission part 5, a central rod 6, a linkage rod 7, a take-up roller 8, and a reciprocating push mechanism. A drive motor 9 is fixed to the top of the float 3. A second transmission part 10 is mounted on the output shaft of the drive motor 9. The second transmission part 10 is coaxial with the output shaft and can drive the first transmission part 5 to rotate. The central rod 6... The device is vertically mounted. The first end of the central rod 6 is fixed to the inner wall of the top of the float 3. The first transmission part 5 is fixedly sleeved on the central rod 6 and can rotate around the central axis of the central rod 6. The linkage rod 7 is parallel to the central axis of the first transmission part 5. One end of the linkage rod 7 is fixedly mounted on the bottom surface of the first transmission part 5. The top of the take-up drum 8 has a mating hole corresponding to the linkage rod 7. The other end of the linkage rod 7 passes through the mating hole. The take-up drum 8 can slide along the axial direction of the linkage rod 7 and rotate around the central axis of the first transmission part 5. The sliding range is limited by the mating length between the linkage rod 7 and the mating hole. The reciprocating push mechanism is fixedly mounted on the inner wall of the bottom of the float 3. The output end of the reciprocating push mechanism contacts the bottom of the take-up drum 8. The reciprocating push mechanism pushes the take-up drum 8 to slide along the linkage rod 7. The take-up drum 8 returns to its original position by its own gravity.
[0032] For the reciprocating push mechanism, a telescopic push rod 12 can be directly installed on the inner wall of the bottom of the float 3. The output end of the telescopic push rod 12 contacts the bottom of the take-up drum 8. Under the pushing action of the telescopic push rod 12, the take-up drum 8 slides upward along the linkage rod 7 without affecting its own rotational movement. When the telescopic push rod 12 retracts, the take-up drum 8 returns to its original position downward by its own gravity. Alternatively, the reciprocating push mechanism includes a plate 11 and a telescopic push rod 12, such as... Figures 2 to 3As shown, a limiting block 13 is fixedly connected to the bottom of the take-up drum 8. Plate 11 is located below the limiting block 13, with its upper surface in contact with the limiting block 13. A hinged support 14 is provided on the inner wall of the bottom of the float 3. Plate 11 has a connecting part 15 at its bottom, which is hinged to the hinged support 14. A telescopic push rod 12 is located on the inner wall of the bottom of the float 3, with its output end hinged to the bottom surface of plate 11. The telescopic push rod 12 pushes plate 11 to reciprocate around the hinged support 14 at a certain angle, causing the upper surface of plate 11 to tilt up and down relative to the horizontal plane. The telescopic push rod 12 drives plate 11 to reciprocate, causing plate 11 to tilt, resulting in a periodic change in the height of the contact point between the take-up drum 8 and plate 11, thereby driving the take-up drum 8 to slide axially along the linkage rod 7.
[0033] like Figure 2 and Figure 3 As shown, the telescopic push rod 12 pushes the plate 11 to reciprocate around the hinge support 14 at a certain angle. The size of this angle needs to be determined based on the diameter D and axial length L of the take-up roller 8 to ensure that the chain 1 is evenly distributed on the take-up roller 8. For example, a certain angle means that the swing angle on one side is 10° or 20° or other angles, that is, the total swing angle is 20° or 40° or other angles. The specific angle needs to be determined in conjunction with the size of the take-up roller 8. The diameter of the take-up roller 8 is D, and the axial length of the take-up roller 8 is L. The swing angle design of the plate 11 should ensure that the chain 1 is evenly distributed within the axial length L of the take-up roller 8, avoiding the accumulation of the chain 1 in a certain local area, thereby achieving neat winding and stable take-up and unwinding of the chain 1.
[0034] like Figure 2 As shown, regarding the installation position of the drive motor 9, it can be installed on the top outer wall of the float 3, with the output shaft of the drive motor 9 passing through both the inner and outer walls of the float 3 and extending into the float 3; alternatively, the drive motor 9 can be installed on the inner wall of the float 3, with its output shaft located inside the float 3. Installing the drive motor 9 on the outer wall of the float 3 facilitates maintenance and heat dissipation, but waterproof sealing needs to be considered; installing it on the inner wall of the float 3 results in a more compact structure, but maintenance is relatively inconvenient.
[0035] For the center rod 6, the center rod 6 mainly serves as the rotation center shaft of the first transmission part 5. The first end of the center rod 6 is fixed to the inner wall of the top of the float 3. The second end of the center rod 6 can be located between the first transmission part 5 and the take-up drum 8. In this case, at least two linkage rods 7 need to be set to ensure that the take-up drum 8 rotates synchronously with the first transmission part 5. Alternatively, a clearance hole 16 can be opened in the center of the plate 11. The second end of the center rod 6 can also pass through the take-up drum 8 and the plate 11 in sequence. The second end of the center rod 6 is fixed to the inner wall of the bottom of the float 3. In this case, only one linkage rod 7 needs to be set. The center rod 6 can serve as the rotation center of the take-up drum 8. In this case, both ends of the center rod 6 are limited and fixed, making the structure more stable and reliable. For the cooperation between the take-up drum 8 and the center rod 6, a clearance through hole is opened in the center of the take-up drum 8. The diameter of the clearance through hole is slightly larger than the diameter of the center rod 6. The center rod 6 and the clearance through hole are clearance-fitted. Alternatively, the diameter of the clearance through hole is much larger than the diameter of the center rod 6. The clearance through hole is used to avoid the center rod 6, and the center rod 6 can pass through the take-up drum 8.
[0036] like Figure 3 As shown, the take-up roller 8 can slide axially along the linkage rod 7 and rotate around the central axis of the first transmission part 5. The sliding range is limited by the length of the linkage rod 7 and the mating hole. Driven by the linkage rod 7, the take-up roller 8 rotates synchronously with the first transmission part 5, pushing the take-up roller 8. The take-up roller 8 can slide axially along the linkage rod 7. It should be noted that the sliding distance of the take-up roller 8 is limited by the length of the linkage rod 7 and the mating hole. During the sliding process, the linkage rod 7 must not disengage from the mating hole at least partially to ensure that the linkage rod 7 and the mating hole are engaged, driving the take-up roller 8 to rotate.
[0037] like Figure 3 As shown, the take-up roller 8 is supported by the limiting block 13. Under the action of the telescopic push rod 12, the plate 11 is tilted relative to the horizontal plane. When the limiting block 13 rotates on the plane of the plate 11, the vertical height of the limiting block 13 changes. That is, when the limiting block 13 is at the lower end of the tilt of the plate 11, the vertical height of the limiting block 13 is the minimum. When the limiting block 13 is at the upper end of the tilt of the plate 11, the vertical height of the limiting block 13 is the maximum. When the limiting block 13 is between the upper and lower ends of the tilt, the vertical height of the limiting block 13 is between the minimum and maximum height. The change in the height of the limiting block 13 pushes the take-up roller 8 to slide along the linkage rod 7 axially, thereby realizing the uniform winding of the chain 1.
[0038] For the telescopic push rod 12, an electric push rod, a telescopic cylinder, or a hydraulic cylinder can be used. There are no special restrictions here, as long as the telescopic pushing effect can be achieved.
[0039] The first transmission unit 5 and the second transmission unit 10 can both be gears, and the first transmission unit 5 and the second transmission unit 10 can mesh with each other. The transmission method between the first transmission unit 5 and the second transmission unit 10 can also be pulley and belt transmission, or chain and gear transmission.
[0040] like Figure 3 As shown, the plate 11 can be a square plate, a round plate, or other plates, without any particular limitation. It is only required that it has a plane that can be tilted under the action of the telescopic push rod 12 to ensure that the take-up roller 8 can slide up and down. In this solution, the plate 11 is preferably a round plate with a clearance hole 16 in the center. The clearance hole 16 is used to avoid the center rod 6, while also reducing the weight of the plate 11 and optimizing the structure.
[0041] Furthermore, the number of linkage rods 7 is preferably two. The linkage rods 7 are located on both sides of the central axis of the first transmission part 5, and the two linkage rods 7 are symmetrically arranged with respect to the central axis of the first transmission part 5. Using two rods can achieve the transmission purpose and reduce manufacturing costs. The linkage rods 7 are located on both sides of the central axis of the first transmission part 5, and the two linkage rods 7 are symmetrically arranged with respect to the central axis of the first transmission part 5. The symmetrical arrangement ensures force balance, ensures that the first transmission part 5 and the take-up roller 8 are subjected to uniform force, and improves stability.
[0042] like Figure 2 and Figure 3 As shown, in this embodiment of the solution, a spring 17 is also included. The second end of the central rod 6 passes through the first transmission part 5, and the spring 17 is sleeved on the central rod 6. One end of the spring 17 abuts against the first transmission part 5, and the other end of the spring 17 abuts against the take-up drum 8. With the second end of the central rod 6 passing through the first transmission part 5, the second end of the central rod 6 can be positioned between the first transmission part 5 and the take-up drum 8. A portion of the spring 17 is sleeved on the central rod 6, while the other portion is not engaged with the central rod 6, yet it still achieves the purpose of extension and retraction, helping the take-up drum 8 to reset. This also facilitates the installation and replacement of the spring 17. Even without the spring 17, the take-up drum 8 can reset itself by its own weight. After the second end of the central rod 6 passes through the first transmission part 5, it can also pass through the take-up drum 8 and the plate 11 in sequence. The second end of the central rod 6 is fixed to the inner wall of the bottom of the float 3. In this case, the spring 17 is entirely sleeved on the central rod 6, preventing the spring 17 from accidentally detaching from the central rod 6 and affecting the reset effect.
[0043] like Figure 1 and Figure 4As shown, the preferred number of pontoons 3 is three, arranged in an equilateral triangle. A connecting rod 18 is also included, with adjacent pontoons 3 connected by the connecting rod 18. The equilateral triangle structure has high mechanical symmetry, enabling even distribution of buoyancy and improving overall stability, especially in waves or currents. The arrangement of three pontoons 3 effectively distributes the load, avoids local overload, ensures balanced system stress, and reduces the risk of tilting or capsizing. Furthermore, this arrangement is structurally simple; the three pontoons 3 form a stable triangular frame through the connecting rod 18, resulting in a concise structure that is easy to manufacture and maintain, while also reducing material costs. More pontoons 3 could further improve stability, but this would increase cost and complexity.
[0044] like Figure 1 As shown, the main body of the wind turbine includes a tower 19 and a wind turbine generator set 20. The bottom end of the tower 19 is fixed on a floating base, and the wind turbine generator set 20 is installed on the upper end of the tower 19.
[0045] like Figure 4 As shown, the structure also includes a fixed base 21 and three support rods 22. The fixed base 21 is bolted to the bottom of the tower 19. The three support rods 22 are arranged in a ring around the central axis of the tower 19, with an included angle of 120° between adjacent support rods 22. One end of each support rod 22 is fixedly connected to the fixed base 21, and the other end is fixedly connected to the pontoon 3. The three support rods 22 are evenly distributed at 120° angles to ensure that the load is evenly distributed to the three pontoons 3, avoiding local stress concentration and improving overall stability. The triangular structure has natural stability and can effectively resist external forces such as wind and waves, preventing the tower 19 from tilting or overturning. The fixed base 21 is bolted to the bottom of the tower 19, facilitating disassembly and maintenance.
