Description

Technical Field

[0001] This invention relates to the field of offshore wind turbine equipment technology, specifically to a deep-sea floating foundation for offshore wind power. Background Technology

[0002] With the global energy structure shifting towards cleaner energy and the increasing saturation of near-shore wind farm resources, offshore wind power development is accelerating its expansion into deep-sea areas with depths exceeding 50 meters. In these areas, traditional fixed foundations are unsuitable due to economic and technical limitations, making floating foundations, which do not require rigid seabed support, a key solution. This technology stabilizes the wind turbine on the sea surface through buoyancy and mooring systems, effectively developing high-quality deep-sea wind energy resources and representing a core technological direction for the future large-scale and commercial development of offshore wind power.

[0003] Traditional devices have the following shortcomings: Currently, mainstream deep-sea floating foundations mainly include semi-submersible and tension leg structures. These foundations typically consist of three main parts: the main structure providing buoyancy, the transition section connecting the wind turbine tower, and the mooring system anchored to the seabed. However, existing technologies face a long-term and severe challenge: the foundation structure is suspended on the sea surface year-round, subjected to continuous, multi-directional impacts from waves. This continuous dynamic load leads to a series of problems: firstly, critical structural nodes are prone to cracking and propagation due to long-term fatigue loads, threatening the overall structural integrity; secondly, the continuous pounding and swaying motion of waves may cause instability in wind turbine operation, exacerbating wear on critical components such as the transmission system, affecting power generation efficiency and the overall lifespan of the turbine. Summary of the Invention

The telescopic sleeve is sleeved on the outside of the lead screw, and one end is rotatably connected to the lead screw. The cylinder of the telescopic sleeve is also slidably connected to the L-shaped support frame. The positioning seats are symmetrically arranged on the ring wall of the positioning toothed ring. Sliding seats are rotatably connected to the two positioning seats. Wave-breaking plates are slidably connected to the sliding seats through through slots. The ends of the two wave-breaking plates are rotatably connected by a rotating shaft. The end of the telescopic sleeve is connected to the rotating shaft at the end of the wave-breaking plate. The telescopic sleeve adjusts the folding angle of the wave-breaking plate by horizontal telescopic adjustment.

[0007] Preferably, the drive mechanism includes: A spur gear shaft is rotatably connected to one end of the cavity of the base seat, and its teeth mesh with the positioning gear ring. A bevel gear shaft is provided inside the cavity of the base seat, and a synchronous belt is connected to the lower end of the bevel gear shaft and the spur gear shaft to ensure that the two shafts rotate synchronously. A transmission ring is rotatably mounted on the upper surface of the base. Both the upper and lower ends of the transmission ring are provided with helical tooth surfaces. The end of the lead screw meshes with the helical tooth surfaces above the transmission ring via a bevel gear. The motor is disposed in the cavity of the base. The output end of the motor is connected to a drive shaft. The other end of the drive shaft is rotatably connected to the inner wall of the cavity of the base through a bearing. Two limiting rings are provided on the drive shaft. A double-sided bevel gear is slidably connected on the drive shaft between the two limiting rings. The two tooth surfaces of the double-sided bevel gear are respectively matched with the helical tooth surface below the drive ring and the conical surface of the bevel gear shaft. An electromagnetic component is disposed on the inner wall of the cavity of the base and on the double-sided bevel gear for adjusting the horizontal position of the double-sided bevel gear on the transmission shaft.

[0008] Preferably, one end of the L-shaped support frame is provided with a rotating seat, the end of the lead screw is rotatably connected to the rotating seat, and a locking element is also provided inside the rotating seat.

[0009] Preferably, the waterproof part includes a base and a top cover. The base is disposed on the upper surface of the foundation seat and located outside the transmission ring. The top cover is disposed on the tower and located above the base. A rotating ring is rotatably connected between the base and the top cover. The ends of the L-shaped support frame and the lead screw both pass through the rotating ring and are located inside it.

[0010] Preferably, the testing organization includes: The detection chamber is located on the outer wall of the base, and a drainage channel is provided at the lower end of the detection chamber. The drainage channel is located above the sea level and its diameter is proportional to the drainage speed. A buoyancy block is movably disposed within the detection chamber. The buoyancy block has drainage holes that accelerate the downward transfer of seawater and increase its own upward speed. A proximity sensor is disposed at the upper end of the detection chamber, and a sensing element matching the proximity sensor is disposed within the buoyancy block.

[0011] Preferably, the controller is electrically connected to the motor, the electromagnetic component, and the proximity sensor via wires.

[0014] Preferably, the upper end of the detection cavity is provided with a waterproof layer on the outside of the proximity sensor.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention incorporates a wave-breaking mechanism. By using a wave-breaking plate to create a conical surface facing the direction of the waves, the incoming waves are split into two streams and guided away, making it difficult for the waves to directly impact the main body of the foundation. The impact force is also effectively dissipated, alleviating fatigue caused by continuous impact on various structural nodes of the foundation, ensuring the stability of the wind turbine operation and the overall lifespan of the unit. At the same time, when adjusting the orientation of the wave-breaking plate, it can be actively retracted first, reducing the resistance of sea wind and waves during rotation, and the overall wind and wave resistance is significantly improved. This invention, by setting up a drive mechanism, uses a single power source to achieve independent control of the wave-breaking plate's angle and overall orientation. The control logic is simple and clear, and the power conversion is rapid and efficient. This not only ensures the effective execution of the wave-breaking function but also improves the overall wind and wave resistance of the foundation. At the same time, the simple structure reduces the production and maintenance costs of the entire wind power foundation, and ensures stability and reliability. This invention incorporates a waterproof section, utilizing a base, top cover, and rotating ring to create a relatively enclosed space. The transmission ring is installed on the inner side, effectively preventing sea waves from penetrating into the foundation base without affecting the power output between the lead screw and the transmission ring, thus further improving the overall lifespan of the wind power foundation. This invention enables rapid determination of wave direction by setting up a detection mechanism and feeding the data back to the controller in real time, which improves the timeliness of wave-breaking mechanism adjustment. Furthermore, the data source does not rely on the wind direction sensor on the top of the fan, avoiding misjudgment when the wind direction and wave direction are inconsistent, and the judgment accuracy is high.

It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0020] As a further improvement of the present invention, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] Please see Figure 1-9 As shown, the present invention provides a technical solution for a deep-sea floating foundation for offshore wind power: a deep-sea floating foundation for offshore wind power includes a foundation base 1 and a tower 2 mounted on the foundation base 1. The foundation base 1 floats or is semi-submerged on the sea surface, and its bottom is connected to a mooring system via a steel structure. A rotatable wave-breaking mechanism 3 is provided at the upper end of the foundation base 1. A drive mechanism 4 for adjusting the wave-breaking angle of the wave-breaking mechanism 3 is provided inside the foundation base 1 through a cavity. A detection mechanism 5 is provided in a ring on the outer wall of the foundation base 1 to determine the direction of the waves. A waterproof part 6 is provided at the upper end of the foundation base 1 outside the tower 2. The waterproof part 6 is movably connected to the wave-breaking mechanism 3 to prevent waves from penetrating the drive mechanism 4. A controller 7 is provided inside the waterproof part 6.

[0022] The wave-breaking mechanism 3 includes a positioning gear ring 301 and a positioning seat 305. The positioning gear ring 301 is rotatably connected to an annular groove on the main body of the base seat 1. An L-shaped support frame 302 is provided on one side of the positioning gear ring 301. A lead screw 303 and a telescopic sleeve 304 are provided at the upper end of the L-shaped support frame 302. One end of the lead screw 303 is rotatably connected to the end of the L-shaped support frame 302. The telescopic sleeve 304 is sleeved on the outside of the lead screw 303, and one end is rotatably connected to the lead screw 303. The cylinder of the telescopic sleeve 304 is also slidably connected to the fixed sleeve at the end of the L-shaped support frame 302. The telescopic sleeve 304 can only slide relative to the fixed sleeve and cannot rotate.

[0023] Positioning seats 305 are fixedly and symmetrically arranged on the ring wall of positioning toothed ring 301. Sliding seats 306 are rotatably connected to the two positioning seats 305. Wave-breaking plates 307 are slidably connected to the sliding seats 306 through through slots. The ends of the two wave-breaking plates 307 are rotatably connected by a rotating shaft. The end of the telescopic sleeve 304 is connected to the rotating shaft at the end of the wave-breaking plate 307. The interior of the wave-breaking plate 307 can be a hollow structure, or a corrosion-resistant low-density material can be used at the bottom to provide buoyancy and reduce the suspension pressure on the telescopic sleeve 304. The telescopic sleeve 304 adjusts the folding angle of the wave-breaking plate 307 by horizontal telescoping. The wave-breaking plate 307 is a consumable part and should be replaced every 1-2 years. Figure 7 As shown, the wave-breaking plate 307 has its maximum angle at this time, and the sliding seat 306 is in a closed state on the positioning seat 305. At this time, the wave-breaking plate 307 can be rotated to adjust the angle, and the resistance from sea waves and sea winds is minimized. Figure 8 As shown, the wave-breaking plate 307 has the smallest included angle at this time, and the wave-breaking effect is best when the included angle faces the direction of the waves. The sliding seat 306 rotates and opens adaptively relative to the positioning seat 305.

[0024] In practical applications, the included angle of the wave-breaking plate 307 should be at its minimum, such as... Figure 8 As shown, when the waves hit the foundation, they can be effectively dispersed and guided by the end of the wave-breaking plate 307, reducing the impact of the waves on the foundation 1. After the wave direction changes and reaches a certain intensity, the controller 7 first judges the wave direction, and then drives the screw 303 to rotate and retract the telescopic sleeve 304 through the drive mechanism 4, so that the included angle of the wave-breaking plate 307 opens to the maximum, as shown. Figure 7 As shown, the rotational resistance is minimal at this point. Then, the positioning gear ring 301 is rotated via the drive mechanism 4 until the ends of the two wave-breaking plates 307 point towards the wave direction. Finally, the lead screw 303 is rotated via the drive mechanism 4 to extend the telescopic sleeve 304, as shown... Figure 8 As shown, the angle of the wave-breaking plate 307 is minimized, resulting in the best wave-breaking effect.

[0025] The wave-breaking mechanism 3 uses wave-breaking plate 307 to create a conical surface facing the direction of the waves, splitting the incoming waves into two streams and guiding them away. This makes it difficult for the waves to directly impact the main body of the foundation 1, and the impact force is also effectively dissipated. This alleviates the fatigue caused by continuous impact on various structural nodes of the foundation, ensuring the stability of the wind turbine operation and the overall lifespan of the unit. At the same time, when adjusting the orientation of wave-breaking plate 307, it can be actively retracted first to reduce the resistance of sea wind and waves during rotation, and the overall wind and wave resistance is significantly improved.

[0026] like Figure 3-6As shown, the drive mechanism 4 includes a spur gear shaft 401, a transmission ring 404, a motor 405, and an electromagnetic assembly 409. The spur gear shaft 401 is rotatably connected to one end of the cavity of the base 1, and its teeth mesh with the positioning gear ring 301. A bevel gear shaft 402 is disposed inside the cavity of the base 1. A synchronous belt 403 is connected to the lower end of the bevel gear shaft 402 and the spur gear shaft 401 to ensure that the two shafts rotate synchronously. The transmission ring 404 is rotatably disposed on the upper end surface of the base 1. The transmission ring 404 reduces the friction between itself and the connecting surface of the base 1 during rotation by means of balls or sliding parts. Both the upper and lower ends of the transmission ring 404 are provided with helical tooth surfaces. The end of the lead screw 303 meshes with the helical tooth surface on the upper part of the transmission ring 404 by means of a bevel gear.

[0027] The motor 405 is mounted in the cavity of the base 1 via a bracket. The output end of the motor 405 is connected to the drive shaft 406. The other end of the drive shaft 406 is rotatably connected to the inner wall of the cavity of the base 1 via a bearing. Two limit rings 407 are provided on the drive shaft 406. A double-sided bevel gear 408 is slidably connected between the two limit rings 407 on the drive shaft 406. The two tooth surfaces of the double-sided bevel gear 408 are respectively matched with the helical tooth surface below the drive ring 404 and the conical surface of the bevel gear shaft 402. The connection section between the drive shaft 406 and the double-sided bevel gear 408 is non-circular to ensure the transmission effect.

[0028] The electromagnetic assembly 409 includes an electromagnet and a permanent magnet. The electromagnet is mounted on the inner wall of the cavity of the base 1, located outside the bearing at the end of the transmission shaft 406. The permanent magnet is mounted on the double-sided bevel gear 408 and matches the electromagnet. The electromagnet generates an attractive or repulsive force on the permanent magnet by controlling the direction of the current, thereby driving the double-sided bevel gear 408 to move horizontally and adjusting its horizontal position on the transmission shaft 406. When the two generate an attractive force, the position of the double-sided bevel gear 408 is as follows: Figure 4 As shown, at this time, the double-sided bevel gear 408 meshes with the transmission ring 404. Conversely, when the two generate a repulsive force, the double-sided bevel gear 408 moves to the other side and meshes with the teeth of the bevel gear shaft 402.

[0029] When it is necessary to adjust the included angle of the wave-breaking plate 307, the electromagnet is energized to generate an attractive force on the double-sided bevel gear 408, causing one side of the double-sided bevel gear 408 to fit against the limiting ring and the teeth to mesh with the transmission ring 404. At this time, the motor 405 is started, and the motor 405 drives the transmission ring 404 to rotate through the double-sided bevel gear 408, thereby driving the lead screw 303 to rotate.

[0030] When it is necessary to adjust the direction of the wave-breaking plate 307 towards the waves, the electromagnet is energized to generate a repulsive force on the double-sided bevel gear 408. The other side of the double-sided bevel gear 408 is in contact with the limiting ring and its teeth are meshed with the teeth of the bevel gear shaft 402. At this time, the motor 405 is started. The motor 405 drives the spur gear shaft 401 to rotate through the double-sided bevel gear 408, the bevel gear shaft 402 and the synchronous belt 403, thereby driving the positioning gear ring 301 to rotate and adjusting the direction of the wave-breaking plate 307.

[0031] Through the drive mechanism 4, an independent control of the included angle and overall orientation of the wave-breaking plate 307 is achieved using a power source. The control logic is simple and clear, and the power conversion is rapid and efficient. This not only ensures the effective execution of the wave-breaking function, but also improves the overall wind and wave resistance of the foundation. At the same time, the structure is simple, which reduces the production and maintenance costs of the entire wind power foundation, and ensures stability and reliability.

[0032] One end of the L-shaped support frame 302 is equipped with a rotating seat 3021. The end of the lead screw 303 is rotatably connected to the rotating seat 3021. A locking component is also provided inside the rotating seat 3021. The locking component can be a retractable positioning block. Several slots are opened on the lead screw 303 to match it. When locking is required, the positioning block can be inserted into any slot to achieve locking. When adjusting the overall orientation of the wave-breaking plate 307, the controller 7 controls the locking component inside the rotating seat 3021 to lock the lead screw 303 and prevent the lead screw 303 from rotating.

[0033] The waterproof section 6 includes a base 601 and a top cover 602. The base 601 is located on the upper surface of the foundation 1, outside the transmission ring 404. The top cover 602 is located on the tower 2, above the base 601. A rotating ring 603 is rotatably connected between the base 601 and the top cover 602. The ends of the L-shaped support frame 302 and the lead screw 303 pass through the rotating ring 603 and are located inside it. Several rollers are provided at the upper and lower ends of the rotating ring 603 to reduce friction with the base 601 and the top cover 602, allowing it to rotate freely between them. When adjusting the overall orientation of the wave-breaking plate 307, the ends of the L-shaped support frame 302 and the lead screw 303 are always located inside the rotating ring 603, and the rotating ring 603 rotates synchronously with the L-shaped support frame 302 and the lead screw 303. Figure 4 As shown, the outer ring of the base 601 is lower than the inner ring to prevent seawater from accumulating in the tank and seeping inward.

[0034] The waterproof section 6, along with the base 601, top cover 602, and rotating ring 603, creates a relatively enclosed space. The transmission ring 404 is installed on the inside, effectively preventing waves from seeping into the foundation base 1 without affecting the power output between the lead screw 303 and the transmission ring 404, thus further improving the overall lifespan of the wind power foundation.

[0035] The detection mechanism 5 includes a detection chamber 501 and a buoyancy block 503. The detection chamber 501 is located on the outer wall of the base 1, and a drainage channel 502 is provided at the lower end of the detection chamber 501. The buoyancy block 503 is movably disposed within the detection chamber 501, and a drainage hole is provided on the buoyancy block 503 to accelerate the downward transfer of seawater and increase its own upward speed. A proximity sensor 504 is provided at the upper end of the detection chamber 501, and a sensing element matching the proximity sensor 504 is provided inside the buoyancy block 503. By reasonably setting the length of the wave-breaking plate 307, it is ensured that the adjacent detection chamber 501 will not be obstructed when the included angle of the wave-breaking plate 307 is at its minimum.

[0036] After a wave is generated, as the wave increases in size, seawater will seep into the detection chamber 501 on the side of the base 1 facing the wave. The frequency and amount of seawater seepage will gradually increase with the wave's size. If the wave is small, less seawater will seep into the detection chamber 501 and can quickly pass through the buoyancy block 503 and be discharged through the drainage channel 502 below. If the wave is large, a large amount of seawater will continuously seep into the detection chamber 501. When the inflow velocity exceeds the outflow velocity, the detection chamber 501 will be filled with seawater, causing the buoyancy block 503 to rise to its highest point and trigger the proximity sensor 504. At this time, the proximity sensor 504 will send an electrical signal to the controller 7. Since the waves are not necessarily continuous and regular, the controller 7 can determine the wave state based on the continuity and frequency of the received electrical signal. The drainage channel 502 is located above the sea level, and its diameter is proportional to the drainage velocity. The faster the drainage velocity, the larger the wave required to trigger the proximity sensor 504.

[0037] The detection mechanism 5 enables rapid determination of the direction of the waves and feeds the data back to the controller 7 in real time, which improves the timeliness of the adjustment of the wave-breaking mechanism 3. Furthermore, the data source does not rely on the wind direction sensor on the top of the fan, thus avoiding misjudgment when the wind direction and the direction of the waves are inconsistent, resulting in high accuracy.

[0038] The controller 7 is electrically connected to the motor 405, the electromagnetic component 409 and the proximity sensor 504 via wires to ensure efficient data transmission.

[0039] A filter screen is installed at the opening of the detection chamber 501 to prevent garbage from entering the detection chamber 501 and causing the proximity sensor 504 to malfunction.

[0040] The number of detection cavities 501 is 6-12, and the specific number can be further determined according to the diameter of the base 1. The detection cavities 501 are evenly distributed on the outer wall of the base 1.

[0041] The upper end of the detection cavity 501 is provided with a waterproof layer on the outside of the proximity sensor 504. The waterproof layer significantly improves the service life of the proximity sensor 504 while ensuring the triggering effect of the sensing element on the proximity sensor 504.
