Description

Technical Field

[0001] The present application relates to the technical field of wind power equipment, and in particular to an active anti-roll device for a floating platform and a floating wind power platform. Background Art

[0002] Floating wind turbine platforms are installed in marine environments and used to support wind turbines to harness offshore wind energy. However, the high risk of environmental fluctuations in the open sea can cause the wind turbines and platforms to sway, impacting power generation efficiency and equipment life. Currently, anti-sway devices are installed on the platforms to counteract the sway of the platform and wind turbines by adjusting the air-water ratio in different areas of the platform to produce different buoyancy effects at different positions on the platform. However, for large platforms, the performance of the ballast pumps and the length of the pipelines are limited, resulting in slow response speeds and long adjustment times. The adjustment rate cannot meet the needs of rapid adjustment at large angles, which can damage the life of the wind turbines and platforms and cause a certain degree of impact on the wind turbine's power generation efficiency.

[0003] Therefore, how to improve the platform's active anti-roll adjustment rate and optimize the offshore wind turbine power generation efficiency is an urgent problem that technical personnel in this field need to solve. Summary of the Invention

[0012] The mounting point of the second driving assembly is arranged on the column or the fixed arm.

[0013] Preferably, in the above-mentioned active anti-roll device for floating platforms, the semi-submersible platform includes three columns, and the mounting point of the second drive assembly is provided on the fixed arm.

[0014] Preferably, in the above-mentioned active anti-rolling device for floating platforms, the second drive assembly is driven by hydraulic pressure or motor, and at least two second drive assemblies are spaced apart on a single set of the guide assemblies.

[0015] Preferably, in the above-mentioned active anti-roll device for a floating platform, the guide assembly includes a base and a guide rod provided on the base, and the guide rod is provided through the counterweight block;

[0016] The first driving assembly includes a driving part and a screw. A nut is fixedly provided on the counterweight and cooperates with the screw. The driving part drives the screw to rotate clockwise and counterclockwise to drive the counterweight to move axially along the guide rod.

[0017] Preferably, in the above-mentioned active anti-roll device for floating platforms, limit switches are arranged at intervals on the base, the limit switches detect the distance between the counterweight block and the end limit position on its running path, and the limit switches are communicatively connected to the controller.

[0018] Preferably, in the above-mentioned floating platform active anti-rolling device, the driving part is a hydraulic motor or an electric motor.

[0019] Preferably, in the above-mentioned active anti-rolling device for floating platforms, at least three groups of the counterweight assemblies are evenly arranged in the circumferential direction of the semi-submersible platform.

[0020] Preferably, in the above-mentioned floating platform active roll stabilization device, the sensor is a fiber optic gyroscope or a MEMS gyroscope and is arranged in the central area of ​​the semi-submersible platform.

[0021] A floating wind power platform comprises the floating platform active anti-roll device described in any one of the above embodiments.

[0022] It can be seen from the above technical solution that one aspect of the present disclosure provides an active roll reduction device for a floating platform, which mainly includes a semi-submersible platform, an adjustment component and a counterweight component, wherein the semi-submersible platform can be floated on the sea surface and support target equipment, such as a wind turbine, etc.; the adjustment component includes a controller and a sensor with communication connections, the sensor is arranged on the semi-submersible platform to detect the angular velocity information of the semi-submersible platform in the roll and pitch directions, and the controller is used to receive real-time detection information from the sensor and calculate the inclination angle of the semi-submersible platform by integration to realize real-time detection of the yaw operation state of the semi-submersible platform. The counterweight assemblies are arranged in several groups along the circumference of the semi-submersible platform, and for a single group of counterweight assemblies, it mainly includes a first drive assembly, a guide assembly and a counterweight block. The counterweight block is arranged on the guide assembly and can move along the guide direction of the guide assembly. The position of the counterweight block in the guide area of ​​the guide assembly is adjusted by the first drive assembly, thereby adjusting the center of gravity position of the semi-submersible platform; and the first drive assembly is communicatively connected with the controller so as to receive the control signal of the controller.

The yaw force of the semi-submersible platform is balanced to achieve roll reduction. Simultaneously, the guide assemblies in the multiple counterweight assemblies are arranged in the same plane and surround the semi-submersible platform. The guide assemblies surrounding the semi-submersible platform enable counterweights to be placed around the circumference of the semi-submersible platform, thereby increasing the adjustment range of the counterweights and achieving more precise roll reduction adjustment for the semi-submersible platform. Furthermore, the guide assemblies arranged in the same plane ensure that the interaction effect of the counterweights on each guide assembly remains uniform, meaning that the distance movement of each counterweight produces the same roll reduction effect on the center of gravity of the semi-submersible platform, making it easier for the controller to find the optimal roll reduction adjustment path during the tilting of the semi-submersible platform. Unlike the prior art, the present invention uses a controller to detect the tilt angle of the semi-submersible platform in real time and provide feedback to the first drive assembly to directly drive the movement of the counterweights to change the center of gravity of the semi-submersible platform. This simple adjustment process and rapid response allow for dynamic adaptation to more complex sea conditions, thereby improving the power generation efficiency of the wind turbine and reducing the lifespan of the floating platform and wind turbine.

[0023] Another aspect of the present disclosure provides a floating wind power platform including the above-mentioned floating platform active anti-roll device, which also has the technical effects of the above-mentioned floating platform active anti-roll device and will not be described in detail here.

[0036] The core of this application is to disclose a floating platform active anti-roll device and a floating wind power platform to improve the platform's active anti-roll adjustment rate and optimize the offshore wind turbine power generation efficiency.

[0037] In order to help those skilled in the art better understand the present invention, the following embodiments of the present invention are described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the invention as described in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not limited to those necessary for the invention as described in the claims.

[0038] like Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides an active anti-roll device for a floating platform, which mainly includes a semi-submersible platform 10, an adjustment component and a counterweight component 30, wherein the semi-submersible platform 10 can be floated on the sea surface and support target equipment, such as a wind turbine, etc., and it uses a distributed buoy structure to achieve a floating setting on the screen, and the adjustment component and the counterweight component 30 are both arranged above the waterline of the semi-submersible platform 10 to reduce the impact of seawater on the service life of the adjustment component and the counterweight component 30.

[0039] The adjustment component is used to detect the real-time operating status of the semi-submersible platform 10. The adjustment component specifically includes a controller and a sensor 20, wherein the sensor 20 is arranged on the semi-submersible platform 10 at a position that is easy to sense the operating status of the semi-submersible platform 10, such as the center position of the semi-submersible platform 10, to detect the angular velocity information of the semi-submersible platform 10 in the roll and pitch directions, and the controller is communicated with the sensor 20 to receive real-time detection information from the sensor 20. The controller receives the angular velocity information of the semi-submersible platform 10 and calculates the inclination angle of the semi-submersible platform 10 through integration to realize real-time detection of the yaw operating status of the semi-submersible platform 10.

[0040] Several groups of counterweight assemblies 30 are arranged along the circumference of the semi-submersible platform 10. A single group of counterweight assemblies 30 primarily comprises a first drive assembly 310, a guide assembly 320, and a counterweight 330. The counterweight 330 is movably mounted on the guide assembly 320 and is adjusted within the guide region of the guide assembly 320 by the first drive assembly 310, thereby adjusting the center of gravity of the semi-submersible platform 10. The first drive assembly 310 is in communication with a controller, enabling the controller to adjust the position of the counterweight 330 through feedback from the first drive assembly 310.

[0041] Based on the above structure, the semi-submersible platform 10 operates within a designed angular range. Deflection within this range is considered safe, and the value of the designed angular range is pre-entered into the controller. When the controller detects that the real-time tilt angle of the semi-submersible platform 10 exceeds the designed angular range, it indicates excessive deflection. The controller then responds to the first drive assembly 310, directing the counterweight 330 in the counterweight assembly 30 to operate within the guide range of the guide assembly 320. For example, if the semi-submersible platform 10 has a high and low side after tilting, the first drive assembly 310 adjusts the counterweight 330 away from the lower side and toward or toward the higher side. This shifts the center of gravity of the semi-submersible platform 10, with the higher side experiencing a greater gravity force, creating a downward motion. This balances the yaw force of the semi-submersible platform 10 and achieves roll reduction. Once the deflection angle of the semi-submersible platform 10 returns to the designed angular range, the controller stops driving the counterweight 330. As for the structure of multiple counterweight assemblies 30 , the controller can simultaneously adjust the positions of multiple counterweight blocks 330 so that they can cooperate and more accurately achieve the balancing effect on the yaw force of the semi-submersible platform 10 .

[0042] It should be noted that the guide assemblies 320 in the several groups of counterweight assemblies 30 are arranged in the same plane. The same plane here specifically means that in the absence of external force, the semi-submersible platform 10 is perpendicular to the sea surface, and the several groups of counterweight assemblies 30 are equidistant from the sea surface and are arranged around the semi-submersible platform 10. The guide assemblies 320 surrounding the semi-submersible platform 10 can provide counterweight blocks 330 in the circumference of the semi-submersible platform 10, thereby increasing the adjustment range of the counterweight blocks 330. When the semi-submersible platform 10 produces a yaw motion in any direction, the combined position adjustment of the counterweight blocks 330 can be used to achieve anti-roll adjustment. The guide assembly 320 arranged on the same plane can keep the effects of the counterweight blocks 330 on each guide assembly 320 uniform. It should be noted that the uniform effect of the counterweight blocks 330 here specifically means that for the counterweight blocks 330 on the same plane, the distance movement of each counterweight block 330 can produce the same adjustment and anti-roll effect on the center of gravity adjustment of the semi-submersible platform 10, and the resultant force of the forces exerted by each counterweight block 330 on the semi-submersible platform 10 can be located on the same setting plane of the guide assembly 320, thereby avoiding the problem that during the combined action of multiple counterweight blocks 330, the forces exerted on the semi-submersible platform 10 are located in different planes and it is difficult to achieve a balancing effect, and it is easier for the controller to find the best anti-roll adjustment path during the tilting process of the semi-submersible platform 10.

[0043] It should be further explained that, unlike the prior art method of adjusting the water volume in the ballast water tank inside the platform column 110 through an active ballast system to adjust the platform's longitudinal inclination angle range to improve the structural stability of the floating foundation, the embodiment of the present disclosure uses a controller to detect the inclination angle of the semi-submersible platform 10 in real time, and feeds back the first drive component 310 to directly drive the movement of the counterweight block 330 to change the center of gravity of the semi-submersible platform 10, thereby achieving the anti-roll effect of the semi-submersible platform 10. It is not limited by the performance of the ballast pump and the length of the pipeline, but has the advantages of a simple adjustment process and a fast response. It can further dynamically adapt to more complex sea conditions, expand the application range of offshore floating wind turbines, improve the power generation efficiency of wind turbines, and reduce the life damage of floating platforms and wind turbines.

[0044] To further enhance the anti-roll effect of the active anti-roll device for the floating platform, in some embodiments of the present disclosure, the active anti-roll device further includes a second drive assembly 40. The guide assembly 320 is floated on the semi-submersible platform 10 and is in transmission connection with the second drive assembly 40, so that the second drive assembly 40 can drive the guide assembly 320 to move away from and toward the axis of the semi-submersible platform 10. The movement of the guide assembly 320 can drive the movement of the counterweight 330, thereby enabling the counterweight 330 to move away from and toward the axis of the semi-submersible platform 10 while moving in a mostly linear direction along the guide direction of the guide assembly 320. This can change the length of the lever arm of the counterweight 330 when applying an anti-roll force to the semi-submersible platform 10. For relatively severe deflection conditions, the first drive assembly 310 and the second drive assembly 40 can cooperate to increase the lever arm of the counterweight 330 when it is in action, thereby making the counterweight 330 more effective in affecting the semi-submersible platform 10 and improving the demand for efficient adjustment in harsh environments.

[0045] It should be noted that the adjustment of the lever arm of the counterweight 330 by the second drive assembly 40 can further improve the adjustment range of the active anti-roll device, provide more comprehensive and accurate adjustment for the semi-submersible platform 10 through the adjustment of the lever arm and the position of the force, and improve the applicability of the floating platform. Figure 2 As shown, for a platform structure with three sets of counterweight components 30, Figure 2 During the deflection to the middle right side, on the one hand, the counterweight block 330 in the counterweight assembly 30 is driven to move away from the lower side of the semi-submersible platform 10; on the other hand, the counterweight assembly 30 away from the lower side of the semi-submersible platform 10 moves further away from the lower side of the semi-submersible platform 10 as a whole under the drive of the second drive assembly 40, so that the corresponding counterweight block 330 has a longer lever arm, which can accelerate the return rate of the semi-submersible platform 10 and improve the adjustment effect.

[0046] On the basis of the above-mentioned embodiment, the guide assembly 320 can realize floating adjustment on the semi-submersible platform 10 through elastic members and telescopic structures. In some embodiments of the present disclosure, the guide assembly 320 realizes floating setting on the semi-submersible platform 10 through the telescopic arm assembly 410. Specifically, Figure 4 and Figure 5 As shown, the telescopic arm assembly 410 includes a moving arm 4120 and a fixed arm 4110. The telescopic arm assembly 410 is fixedly connected to the column 110 of the semi-submersible platform 10 via the fixed arm 4110, while the moving arm 4120 is fixedly connected to one side of the guide assembly 320. Through the telescopic movement of the moving arm 4120 based on the fixed arm 4110, the guide assembly 320 can be moved away from and toward the semi-submersible platform 10, thereby adjusting the force arm of the counterweight 330 on the semi-submersible platform 10. The second drive assembly 40 can directly drive the guide assembly 320 to adjust the position of the guide assembly 320. It should also be noted that the second drive assembly 40 can be installed on the column 110 of the semi-submersible platform 10 or the fixed arm 4110 of the telescopic arm assembly 410 to maintain the stability of the position of its basic bearing point. It should be noted that the installation point of the second drive assembly 40 can be reasonably selected according to the installation position of the tower and the wind turbine on the semi-submersible platform 10 to ensure the installation requirements of the tower and the wind turbine.

[0047] In addition, in some embodiments of the present disclosure, the guide assembly 320 can be floated with the semi-submersible platform 10 through a limit member. Specifically, the limit member is a hollow box structure, one end of which is fixedly arranged on the column 110 of the semi-submersible platform 10; and a partial area of ​​the guide assembly 320 is raised and embedded in the limit member, and the second drive assembly 40 can directly act on the guide assembly 320. In the process of pushing and pulling back the guide assembly 320 by the second drive assembly 40, the guide assembly 320 always keeps a partial area embedded in the limit member to ensure the connection effect between the guide assembly 320 and the column 110, thereby achieving the stability of the guide assembly 320 in the process of moving away from and approaching the semi-submersible platform 10.

[0048] In other embodiments, the guide assembly 320 can also be floatingly connected to the semi-submersible platform 10 through an elastic member with an elastic effect, and the second drive assembly 40 can adopt a hydraulic cylinder, which directly drives the position adjustment of the guide assembly 320 through the telescopic effect of the hydraulic cylinder, and at the same time maintains the connection effect of the guide assembly 320 and the semi-submersible platform 10 with the help of the elastic member.

[0049] Furthermore, in a specific embodiment of the present disclosure, the semi-submersible platform 10 includes three columns 110, and the installation point of the second drive assembly 40 is set on the fixed arm 4110 to reduce the impact of the assembly of the second drive assembly 40 on the subsequent tower and wind turbine installation; and for the semi-submersible platform 10 with a four-column 110 structure, it has a larger column 110 installation space, so the installation point of the second drive assembly 40 can be freely set on the column 110 and the fixed arm 4110.

[0050] To enhance the stability of the second drive assembly 40 in driving the guide assembly 320, the floating platform active anti-roll device provided in the disclosed embodiment includes at least two second drive assemblies 40 spaced apart on a single guide assembly 320. These at least two second drive assemblies 40 are positioned on either side of the guide assembly 320 in the longitudinal direction and symmetrically arranged about the line of symmetry of the guide assembly 320. The second drive assemblies 40 connected to a single guide assembly 320 move synchronously, thereby enhancing the stability of the guide assembly 320's movement away from and toward the semi-submersible platform 10 through multi-point drive. It should be noted that the second drive assembly 40 can be driven hydraulically or electrically to meet stable driving requirements.

[0051] Furthermore, the guide assembly 320 can achieve sliding guidance of the counterweight 330 through structures such as interlocking slide rails and sliders, meshing gear racks, or guide columns. In some embodiments of the present disclosure, such as Figure 1 and Figure 3 As shown, the guide assembly 320 includes a base 3210 and a guide rod 3220 disposed on the base 3210. Two or more guide rods 3220 are provided, and the counterweight 330 is provided through the guide rod 3220 to guide the operation of the counterweight 330. At the same time, the first drive assembly 310 includes a drive unit 3110 and a screw 3120. The screw 3120 is provided parallel to the guide rod 3220 and also passes through the counterweight 330. A nut 3310 is fixedly provided on the counterweight 330 and cooperates with the screw 3120. The drive unit 3110 can drive the screw 3120 to perform clockwise and counterclockwise rotational motion, thereby adjusting the position of the counterweight 330 in the axial direction of the screw 3120 and the guide rod 3220.

[0052] It should be further explained that, in a specific embodiment of the present disclosure, the driving part 3110 is a hydraulic motor and is connected to the screw 3120 through a coupling 3130 to drive the stable rotation of the screw 3120, and the two ends of the screw 3120 are kept stable in position during the rotation process by the support base 3140, thereby achieving stable driving of the counterweight 330. At the same time, in some embodiments, such as Figure 5As shown, the counterweight block 330 adopts a concrete columnar structure to maintain a sufficient counterweight effect. In order to improve the convenience of production and assembly, the counterweight block 330 is fixed on the bearing seat 3320. A hole structure is processed on the bearing seat 3320, and the guide rod 3220 and the lead screw 3120 are both set through the hole structure on the bearing seat 3320. The nut 3310 is set on the bearing seat 3320 to achieve the adjustment of the counterweight block 330 by guiding and driving the bearing seat 3320.

[0053] In order to further optimize the above technical solution and reduce the risk of collision damage of the counterweight block 330 to the guide assembly 320, in some embodiments of the present disclosure, limit switches 3230 are arranged at intervals on the base 3210. It should be noted that the limit switch 3230 can be a solid flexible material to block and limit the counterweight block 330 at the extreme position during the movement of the counterweight block 330; similarly, the limit switch 3230 can also be a visual sensor or distance sensor element. The limit switch 3230 is communicated with the controller and is used to detect the distance between the counterweight block 330 and the extreme position of the end of the base 3210 on its running path. The limit switch 3230 feeds back the detected distance information to the controller. The controller can feedback the first drive assembly 310 to stop driving the counterweight block 330 when the counterweight block 330 is about to run to the extreme position of the end of the base 3210, thereby avoiding the counterweight block 330 with a larger mass from causing collision damage to the end of the base 3210.

[0054] It should be noted that two limit switches 3230 are preferably provided, and the distance between the two limit switches 3230 covers the running path of the counterweight block 330, so as to achieve more accurate distance detection of the counterweight block 330 from both sides.

[0055] Furthermore, in some embodiments of the present disclosure, the active anti-roll device of the floating platform includes at least three groups of counterweight assemblies 30, and the at least three groups of counterweight assemblies 30 are evenly arranged around the circumference of the semi-submersible platform 10, so that the circumference of the semi-submersible platform 10 has a more uniform force distribution and will not produce deflection in the absence of external force. At the same time, compared with one or two counterweight assemblies 30, the arrangement of at least three counterweight assemblies 30 can cooperate to achieve the application of force at various positions around the semi-submersible platform 10 through the composite force effect, thereby meeting the anti-roll adjustment requirements under complex working conditions.

[0056] Furthermore, in the floating platform active roll stabilization device provided in the embodiments of the present disclosure, the drive unit 3110 is a hydraulic motor or an electric motor. The controller can be a PLC (Programmable Logic Controller), a single-chip microcomputer, or a CPU (Central Processing Unit). The sensor 20 for detecting the operating posture of the semi-submersible platform 10 can be a fiber optic gyroscope, which uses the interference effect of light in a fiber optic loop to detect angular velocity and feed the angular velocity information back to the controller for processing. Similarly, it can also be a MEMS (Micro-Mechanical Gyroscope) to detect and provide feedback on the operating posture of the semi-submersible platform 10.

[0057] Furthermore, the embodiments of the present disclosure also disclose a floating wind power platform, which is used to support wind turbines for installation on the sea surface. It should be noted that the floating wind power platform is provided with the floating platform active anti-roll device provided by any of the above embodiments; since the floating platform active anti-roll device has the technical effects provided by any of the above embodiments, the floating wind power platform also has the above technical effects, which will not be repeated here.
