Description

Technical Field

[0001] The present invention relates to the technical field of floating wind turbines, and in particular to a barge-type floating wind turbine capable of avoiding resonance between a wave cycle and the wind turbine. Background Art

[0002] As the demand for renewable energy increases, offshore wind power, as an important form of energy, has been widely used around the world. As the core equipment for developing offshore wind energy, offshore wind turbines are of irreplaceable importance. They make full use of the stable and strong wind resources of the ocean, and their power generation efficiency is significantly higher than that of onshore wind power. At the same time, they avoid the problem of land occupation, and are particularly suitable for deployment in coastal areas where land resources are scarce but electricity demand is strong. With breakthroughs in technologies such as floating, offshore wind turbines have been able to expand to deep seas.

[0003] A Chinese patent (announcement number: CN118327900B; announcement date: 2024-08-23) discloses a split floating wind turbine base and a floating wind turbine. The split floating wind turbine base and the main buoy and auxiliary buoy combination of the floating wind turbine form a floating seat floating on the sea surface, the positioning ring sinks to the seabed with the counterweight of the counterweight, and a plurality of cables pull a plurality of auxiliary buoys respectively, thereby pressing the floating seat to float on the sea surface. The sliding cooperation between the cable and the buckle and the elastic pressure of the movable block on the limit spring make it possible for the cable to always remain taut under the elastic force adjustment of the limit spring when the floating seat sinks or rises due to wind and waves, so as to ensure that the floating seat is pressed to float on the sea surface and sufficient pulling and buoyancy force is applied to the floating seat. A plurality of cables are pulled from different directions, thereby reducing the heaving motion and swinging freedom of the floating seat caused by wind and waves, thereby ensuring the energy collection effect of the wind turbine.

[0004] The wind turbine buoy disclosed in the above patent document relies on a multi-cable pulling system to reduce the wind turbine swing. The passive elastic adjustment mechanism relies heavily on the static coordination of the cable and the limit spring, which is prone to chain instability due to single-point failure. It is also difficult to adapt to the dynamic changes of wave frequency in real time, resulting in tension imbalance (such as local cable overload or relaxation) in complex sea conditions, which in turn causes the risk of oscillation and even resonance of the buoyant body. The dynamic response accuracy is overly dependent on the cable design accuracy, with low fault tolerance and prone to insufficient adjustment accuracy. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present invention is to propose a barge-type floating wind turbine that avoids resonance between wave periods and wind turbines. The barge-type floating wind turbine that avoids resonance between wave periods and wind turbines is actively coordinated and controlled by an adjustable damping pool, an anti-roll plate and a permeable structure. Compared with a single adjustment mechanism, the fault tolerance rate is higher, the dynamic response accuracy and extreme environment adaptability are significantly improved, and the dependence on anchoring is greatly reduced, so as to achieve the dynamic dissipation of wave energy and avoid the risk of floating body resonance, and the response speed is fast and the adjustment accuracy is high.

[0006] A barge-type floating wind turbine for avoiding resonance between wave period and wind turbine according to an embodiment of the present invention comprises: a floating body and a wind turbine, wherein the floating body is connected to the wind turbine; a through slot is provided in the middle of the floating body, and a first adjustment plate and a second adjustment plate which can move crosswise are arranged in the extension direction of the through slot by a first slide rail locking mechanism, and the first adjustment plate and the second adjustment plate divide the through slot into a plurality of damping pools of adjustable size, wherein the extension direction of each damping pool is consistent with the through slot; a plurality of water-permeable holes connected to the through slot are provided around the floating body; a plurality of fixed ballast tanks, a plurality of variable ballast water tanks and a plurality of buoyancy tanks are sequentially provided on the floating body in the extension direction; and anti-roll plates which can slide along the extension direction are provided around the floating body by a second slide rail locking mechanism.

[0007] In the embodiment of the present invention, active control and dynamic response optimization of offshore wind turbines are achieved through the synergistic effect of multiple components. Specifically, the first and second adjustment plates (through the slide rail locking mechanism) that can cross-move through the through slot can dynamically adjust the volume distribution of each damping pool, and by changing the liquid damping distribution and the system inertia, the wave frequency can be matched in real time to avoid resonance; the water-permeable holes allow seawater to flow freely, reducing the lift fluctuations under the floating body, and combining the linkage adjustment of the fixed ballast tank, the variable ballast water tank and the buoyancy tank (changing the center of gravity and buoyancy ratio by filling and draining water) to achieve rapid stabilization of the floating body's attitude; the anti-roll plates around slide along the extension direction (through the second slide rail locking mechanism), and by adjusting the immersion depth and contact area, the swaying degrees of freedom in different directions are actively suppressed. These structures form a closed-loop feedback. When the wave period changes, the regulating plate and the anti-roll plate displace in coordination, the permeable holes dissipate energy, and the ballast system compensates for the buoyancy imbalance, ultimately achieving dynamic dissipation of wave energy, active avoidance of resonant frequencies, and self-stabilization of the floating body under extreme sea conditions. This significantly reduces dependence on the mooring system and effectively improves the response speed and self-stabilization adjustment accuracy.

[0010] Optionally, a plurality of strip grooves are provided in the first adjustment plate and the second adjustment plate, and the arrangement direction of each strip groove is perpendicular to the extension direction; the strip grooves in the first adjustment plate and the strip grooves in the second adjustment plate are overlapped in sequence along the extension direction to form a nested structure for supporting cross-movement between the first adjustment plate and the second adjustment plate.

[0020] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0021] Reference below Figure 1-Figure 8 A barge-type floating wind turbine 100 is described according to an embodiment of the present invention for preventing resonance between wave periods and the wind turbine.

[0022] Combination Figure 1-Figure 8As shown, the barge-type floating wind turbine 100 for avoiding resonance between wave cycle and wind turbine according to the present invention can mainly include: a floating body 10 and a wind turbine 20, wherein the floating body 10 is connected to the wind turbine 20. A through slot 101 is provided in the middle of the floating body 10, and a first adjustment plate 103 and a second adjustment plate 104 that can cross and move are arranged in the extension direction of the through slot 101 through a first slide rail locking mechanism 102. The first adjustment plate 103 and the second adjustment plate 104 divide the through slot 101 into a plurality of damping pools 105 of adjustable size, wherein the extension direction of each damping pool 105 is consistent with the through slot 101. A plurality of water-permeable holes 106 connected to the through slot 101 are provided around the floating body 10. A plurality of fixed ballast tanks 107, a plurality of variable ballast water tanks 108 and a plurality of buoyancy tanks 109 are sequentially provided on the floating body 10 in the extension direction. Stabilizing plates 111 that can slide along the extension direction are arranged around the floating body 10 through the second slide rail locking mechanism 110 .

[0023] Specifically, by designing multiple damping pools 105 inside the floating body 10, the volume of each damping pool 105 can be changed by an adjustable device composed of a first adjustment plate 103 and a second adjustment plate 104, so that the size of each damping pool 105 can be adjusted according to the wave cycle of the marine environment. Through this structural design, the natural vibration cycle of the wind turbine can be flexibly adjusted to avoid resonance with the wave cycle. The adjustment of the damping pool 105 is completed by the first slide rail locking mechanism 102. After adjusting to the specified position, the slider is locked by the first slide rail locking mechanism 102, thereby ensuring that the damping pool 105 can respond to changes in sea conditions in real time.

[0024] Furthermore, the design of the external anti-roll plate 111 adopts a vertical slide rail, that is, an installation method that is consistent with the extension direction of the through slot 101, so that the anti-roll plate 111 can freely adjust the height position in the vertical direction. The function of the anti-roll plate 111 is to reduce the swing effect of waves on the wind turbine platform by changing the floating stability of the wind turbine system. The adjustment of the anti-roll plate 111 can not only effectively reduce the swing of the wind turbine 20, but also can be adjusted in real time according to different wave conditions to achieve the best stabilization effect. Similarly, the adjustment of the anti-roll plate 111 is also completed by a second slide rail locking mechanism 110 similar to the first slide rail locking mechanism 102.

[0025] Furthermore, the design of the floating body 10 also takes into account the arrangement of the water holes 106. The layout of the water holes 106 allows seawater to flow into and out of the floating body 10, reducing the pressure difference caused by waves on the bottom of the floating body 10. This design greatly reduces the lift fluctuation caused by waves and improves the stability of the wind turbine 20. The design of the water holes 106 also enhances the wave impact resistance of the floating body 10 and reduces the risk of the wind turbine 20 being impacted by waves.

[0026] Furthermore, by designing the fixed ballast tank 107, the variable ballast tank 108 and the buoyancy tank 110, the barge-type floating wind turbine 100 can adaptively adjust the center of gravity and buoyancy during long-term operation, thereby ensuring long-term stable operation and extending the service life of the equipment.

[0027] It should be noted that the structure of the barge-type floating wind turbine 100 can not only avoid resonance with the wave cycle, but also maintain high stability in various marine environments, significantly improving the reliability and adaptability of the barge-type floating wind turbine 100. The dynamic response of the barge-type floating wind turbine 100 in a wave environment is faster, ensuring the efficient operation of the barge-type floating wind turbine 100 and effectively extending its service life. Through the coordinated work of the damping tank 105, the anti-roll plate 111 and the water-permeable hole 106, the adaptive adjustment of the wind turbine system in different wave environments is achieved, so that it can respond quickly and maintain stable operation when facing different types of waves, thereby solving the problem that the existing floating wind turbines are easily affected by wave interference and resonance.

[0028] In actual application, active control and dynamic response optimization of offshore wind turbines are achieved through the synergy of multiple components. Specifically, the first adjustment plate 103 and the second adjustment plate 104 (through the slide rail locking mechanism) that can cross-move through the through slot 101 can dynamically adjust the volume distribution of each damping pool, and by changing the liquid damping distribution and the system inertia, the wave frequency can be matched in real time to avoid resonance. The permeable holes 106 allow seawater to flow freely, reduce the lift fluctuations under the floating body, and combine the linkage adjustment of the fixed ballast tank 107, the variable ballast water tank 108 and the buoyancy tank 109 (by filling and draining water to change the center of gravity and buoyancy ratio) to achieve rapid stabilization of the attitude of the floating body 10. The surrounding anti-roll plates 111 slide along the extension direction (through the second slide rail locking mechanism), and actively suppress the swing freedom in different directions by adjusting the immersion depth and contact area. These structures form a closed-loop feedback. When the wave period changes, the adjustment plate and the anti-roll plate 111 move in coordination, the permeable holes 106 dissipate energy, and the variable ballast water reservoir 108 compensates for the buoyancy imbalance, ultimately achieving dynamic dissipation of wave energy, active avoidance of resonant frequencies, and self-stabilization of the floating body 10 under extreme sea conditions, significantly reducing dependence on the mooring system and effectively improving the response speed and self-stabilization adjustment accuracy.

[0029] In a possible implementation, the wind turbine 20 includes a wind turbine tower 201 , wind turbine blades 202 , and a wind turbine nacelle 203 . The floating body 10 is connected to the wind turbine 20 via the wind turbine tower 201 .

[0030] It should be noted that the floating body 10 is connected to the wind turbine 20 through the wind turbine tower 201. The wind turbine tower 201 serves as a supporting structure to transmit the stability of the floating body 10 to the nacelle and blades of the wind turbine, ensuring that it maintains a vertical posture on the barge-type platform, while adapting to the dynamic effects of waves and wind to ensure power generation efficiency and structural safety.

[0031] In a possible implementation, both the first adjustment plate 103 and the second adjustment plate 104 are provided with an adjustment plate slider 1031 and an adjustment plate hydraulic locking mechanism 1032. An adjustment plate hydraulic slide rail 1011 matching the adjustment plate slider 1031 is provided at the uppermost edge of the through slot 101 in the extension direction. Each adjustment plate slider 1031, the adjustment plate hydraulic locking mechanism 1032 and the adjustment plate hydraulic slide rail 1011 form a first slide rail locking mechanism 102, which is used to adjust the relative position of the first panel and the second panel to form a plurality of damping pools 105 of adjustable size.

[0032] Specifically, the first adjustment plate 103 and the second adjustment plate 104 are matched with the hydraulic slide rail that runs through the top of the through slot 101 through the adjustment plate slider 1031, and the cross movement and fixation are realized by the hydraulic locking mechanism: when the wave period changes, the hydraulic system drives the slider to slide along the slide rail, and adjusts the cross distance between the two plates to dynamically divide the volume of each damping pool 105, thereby changing the liquid damping distribution. The locking mechanism then locks the position to maintain stability. By adjusting the size of the damping pool 105, the inertia and vibration frequency of the system can be flexibly adjusted to actively avoid the risk of wave period resonance.

[0033] Optionally, the adjusting plate slider 1031 and the anti-roll plate slider 1101 may be made of steel and have a rectangular structure with a size of 0.2m×0.2m×0.1m.

[0034] In a possible implementation, a plurality of strip grooves are provided in the first adjustment plate 103 and the second adjustment plate 104, and the arrangement direction of each strip groove is perpendicular to the extension direction. The strip grooves in the first adjustment plate 103 and the strip grooves in the second adjustment plate 104 are sequentially overlapped along the extension direction to form a nested structure for supporting the cross movement between the first adjustment plate 103 and the second adjustment plate 104.

[0035] It should be noted that the first adjustment plate 103 and the second adjustment plate 104 form a nested structure through the strip grooves perpendicular to the extension direction: the strip grooves of the two plates overlap along the extension direction, forming a sliding interface similar to gear meshing, allowing the two plates to cross-displace along the slide rail under hydraulic drive (such as XY axis), while the nested meshing design enhances the structural rigidity and avoids lateral deviation. The clearance fit of the strip grooves not only provides sliding freedom, but also limits unnecessary vibrations through the contact of the groove wall, thereby accurately adjusting the division ratio of the damping pool, realizing active matching of the inertia moment and the wave period, and finally ensuring the stability and impact resistance of dynamic adjustment through the coordination of mechanical limit and hydraulic locking.

[0036] In a possible implementation manner, a plurality of water-permeable holes 106 are formed around the floating body 10 to form a mesh structure for connecting the through-groove 101 and the outside of the floating body 10 .

[0037] It should be noted that the water-permeable holes 106 arranged around the floating body 10 are arranged through a mesh structure, so that the through grooves 101 are connected with the external seawater in multiple paths, and the pressure fluctuations inside and outside the floating body are balanced by the principles of fluid mechanics. At the same time, the holes in the mesh structure disperse and guide the flow to weaken local vortex-induced vibrations, thereby reducing the structural fatigue of the floating body caused by wave impact and maintaining dynamic balance.

[0038] Specifically, water permeability n = (water permeability area S1 / floating structure wave-facing area S2) × 100%. Generally, the water permeability of a barge-type floating wind turbine should be controlled between 10% and 40%, and adjusted according to the specific marine environment, wave conditions and the size of the floating body to ensure that the floating body is stable while effectively reducing the impact of waves on it.

[0039] In a possible implementation manner, the shapes of the water permeable holes 106 include circular, elliptical, honeycomb, and polygonal.

[0040] It is understandable that the permeable holes 106 can be designed in various shapes such as circular, elliptical, honeycomb and polygonal: circular holes are conducive to uniformly dispersing water flow impact, the honeycomb structure improves porosity and structural strength through hexagonal nesting, polygonal holes can directionally guide flow and weaken vortices, and elliptical holes can adapt to asymmetric wave pressure distribution. The combination of various shapes forms a gradient permeable effect through a mesh layout, synergistically optimizes the fluid exchange efficiency and resistance balance inside and outside the float, and enhances adaptability to complex wave frequency bands.

[0041] In a possible implementation manner, the shape of the anti-roll plate 111 includes a rectangle, a square, and a plum blossom.

[0042] It is understandable that the rectangular and square designs of the anti-roll plate 111 provide a stable resistance surface through regular geometric shapes, suppressing horizontal sway under conventional wave impact. The plum blossom-shaped anti-roll plate uses petal-shaped edges to form multi-directional guide grooves, which can disperse eddies and enhance turbulent energy consumption, especially in oblique waves or complex flow states, and can dynamically weaken the coupled vibration of heave and roll. The three shapes can be adapted to different sea conditions and can be used in combination or alone, taking into account both structural strength and fluid dynamics optimization.

[0043] In a possible implementation, a plurality of anti-roll plate sliders 1101 and anti-roll plate hydraulic locking mechanisms 1102 are provided on the anti-roll plate 111. A plurality of anti-roll plate hydraulic slide rails 112 matching the anti-roll plate sliders 1101 are provided around the floating body 10 in the extension direction. The anti-roll plate sliders 1101, the anti-roll plate hydraulic locking mechanisms 1102 and the anti-roll plate hydraulic slide rails 112 form a second slide rail locking mechanism 110, which is used to control the sliding of the anti-roll plate 111 on the floating body 10 to adjust the position of the anti-roll plate 111 in the extension direction.

[0044] It should be noted that the anti-roll plate 111 cooperates with the hydraulic slide rails 112 around the floating body 10 through the slider 1101 to form a second slide rail locking mechanism 110 that can be slid and adjusted: the hydraulic system drives the slider to slide along the slide rail in the extension direction, driving the anti-roll plate to change the immersion depth and the flow area, thereby adjusting the resistance distribution. The locking mechanism 1102 locks the slider at the target position to ensure the stability of the anti-roll plate. This design can optimize the sway suppression effect for different wave frequencies (such as long-period surges or short-period breaking waves) by dynamically adjusting the extension length of the anti-roll plate, while avoiding local stress concentration caused by fixed installation, and improving the adaptability of the floating body in complex sea conditions.

[0045] In a possible implementation manner, each stabilization plate hydraulic slide rail 112 is parallel to each other.

[0046] It can be understood that the design of the hydraulic slide rails 112 of each anti-roll plate being parallel to each other ensures that all the anti-roll plates 111 are adjusted synchronously in the same direction through a unified motion axis, thereby avoiding interference in the movement of the plate body or local stress concentration due to the deflection of the slide rails. At the same time, the uniformity of the spacing between the anti-roll plates is maintained through the equidistant constraints of the parallel slide rails, so that a symmetrically distributed resistance surface is formed under the impact of waves, thereby improving the stability and anti-yaw capability of the coordinated anti-roll of multiple plates.

[0047] In a possible implementation manner, the device further includes: a plurality of mooring lines 113 . Each mooring line 113 is connected to the floating body 10 .

[0048] It should be noted that multiple mooring lines 113 are radially distributed and connected to multiple points of the floating body 10, and the positioning constraint of the floating body is realized through the deep-sea anchoring system: each mooring line adopts a redundant design, pulling the floating body from different directions to disperse the force, which can not only suppress the drift or rotation of the floating body caused by wind and waves, but also compensate for tidal water level changes through adaptive tension adjustment, thereby maintaining the stability of the floating body's posture and the verticality of the wind turbine tower under complex sea conditions, while reducing the risk of systemic instability caused by the breakage of a single mooring line 113.

[0049] For example, the floating structure 10 can be a hollow rectangular parallelepiped structure of 100m×100m×34m. The hollow part can be a through slot 101 structure of 60m×60m×34m to form a plurality of damping pools 105. The water-permeable hole can be a circular structure with a diameter of 0.5m. Among them, the damping pool 105 plays a role in increasing the damping of the system. By changing the size and structure of the damping pool 105, the vibration characteristics of the system can be effectively changed. For example, increasing the volume of the damping pool 105 is equivalent to increasing the damping of the system, which can effectively reduce the vibration response of the system and reduce the risk of resonance with the external wave cycle. In particular, when waves interact with the liquid in the damping pool 105, the flow characteristics and damping effect of the liquid will change the dynamic response of the system. By controlling the speed and direction of the liquid flow, the effect of the damping pool 105 can be flexibly adjusted to avoid resonance with the wave cycle.

[0050] Secondly, the first adjustment plate 103 and the second adjustment plate 104 can be automatically or manually adjusted under the influence of waves, thereby dynamically adjusting the natural vibration frequency of the floating body to avoid resonance with the period of the surrounding waves. The first slide rail locking mechanism of the adjustment plate is configured with a locking mechanism to ensure that the adjustment plate can be stably locked in the desired position after adjustment.

[0051] In actual application, the core advantage of the barge-type floating wind turbine 100 structure lies in its active control mechanism of multi-system coordination: the adjustable damping pool 105 adjusts the volume distribution in real time through the cross sliding of the first and second adjustment plates, combined with the mesh diversion of the water-permeable holes 106, dynamically dissipates wave energy and avoids resonant frequency. The hydraulically driven anti-roll plate accurately adjusts the immersion depth along the slide rail to suppress multi-degree-of-freedom swing. The fixed ballast tank 107 and the variable ballast water tank 108 are linked to compensate for buoyancy imbalance, and the redundant mooring line 113 disperses the anchoring stress. The various components work together through closed-loop feedback, significantly improving the self-stability, response speed and environmental adaptability of the floating body under extreme sea conditions, reducing dependence on traditional anchoring, and at the same time extending the structural life and ensuring the continuity of the wind turbine's power generation efficiency through active dissipation of wave energy and optimized stress distribution.
