Description

Technical Field

[0001] The invention relates to the technical field of spoiler structures, and in particular to a floating column spoiler structure, a floating column and a floating fan. Background Art

[0002] At present, offshore wind turbines are usually equipped with floating platforms to support floating wind turbines, and cylindrical floating columns are usually arranged at the bottom of the floating platforms. When the ocean current flows through the floating columns, Karman vortexes often occur around the floating columns, causing the floating columns to often experience vortex-induced vibrations, resulting in the floating wind turbines often having excessive inclination angles or excessive roll and pitch angles, which reduces the stability of the floating wind turbines and affects the stable output of the floating wind turbine power.

[0003] Therefore, how to improve the stability of floating wind turbines is a technical problem that technical personnel in this field currently need to solve. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a floating column spoiler structure to improve the stability of a floating wind turbine.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A floating column spoiler structure, comprising:

[0007] Multiple spoilers;

[0008] A lifting and unfolding assembly connecting the spoiler and the column, the lifting and unfolding assembly comprising a first connecting rod, a second connecting rod, a first gear and a second gear, the first end of the first connecting rod and the first end of the second connecting rod being rotatably connected, and the spoiler being arranged at the first end of the first connecting rod and the first end of the second connecting rod, the second end of the first connecting rod being rotatably connected to the first gear, and the second end of the second connecting rod being rotatably connected to the second gear; the first gear and the second gear are sequentially arranged on the outer circumferential wall of the column from top to bottom along the axial direction of the column, and the outer circumferential wall of the column is provided with lifting gear teeth that can mesh with the first gear and the second gear.

[0009] Optionally, in the above-mentioned floating column spoiler structure, the spoiler is rotatably disposed on the first end of the first connecting rod and the first end of the second connecting rod.

[0010] Optionally, in the above-mentioned floating column spoiler structure, the first end of the first connecting rod and the first end of the second connecting rod are connected by a ball joint.

[0011] Optionally, in the above-mentioned floating column spoiler structure, the spoiler plate includes a spoiler net or a spoiler spike.

[0012] Optionally, in the above-mentioned floating column spoiler structure, the number of lifting and deploying components corresponding to each spoiler is three groups, and the three groups of lifting and deploying components are respectively a first lifting and deploying component, a second lifting and deploying component and a third lifting and deploying component, and the connection positions of the first lifting and deploying component, the second lifting and deploying component and the third lifting and deploying component and the spoiler are distributed in a triangular shape.

[0013] Optionally, in the above floating column spoiler structure, the lifting gear teeth are directly opened on the outer circumferential wall of the column, or a toothed belt is provided on the outer circumferential wall of the column, and the lifting gear teeth are located on the toothed belt.

[0014] Optionally, in the above-mentioned floating column spoiler structure, the first gear and the second gear are respectively arranged on the outer circumferential wall of the column through a first gear mounting member and a second gear mounting member, and the first gear mounting member and the second gear mounting member are slidably connected to the outer circumferential wall of the column.

[0015] Optionally, the above-mentioned floating column spoiler structure also includes a central control system, a water flow velocity monitoring system and a wind and wave environment monitoring system, as well as a first pushing member for pushing the second end of the first connecting rod to rise and fall and a second pushing member for pushing the second end of the second connecting rod to rise and fall. The central control system can transmit signals with the water flow velocity monitoring system, the wind and wave environment monitoring system, the first pushing member and the second pushing member.

[0016] A floating column comprises the floating column spoiler structure as described above.

[0017] A floating wind turbine comprises the floating column spoiler structure as described above.

[0018] When using the floating column spoiler structure provided by the present invention, since the first end of the first connecting rod and the first end of the second connecting rod are rotationally connected, the second end of the first connecting rod is rotationally connected to the first gear, and the second end of the second connecting rod is rotationally connected to the second gear, the first gear and the second gear are sequentially arranged on the outer circumferential wall of the column from top to bottom along the axial direction of the column, and the outer circumferential wall of the column is provided with lifting gear teeth that can mesh with the first gear and the second gear; therefore, by moving at least one of the first gear and the second gear along the axial direction of the column, the distance between the first gear and the second gear can be adjusted, so that the distance between the second end of the first connecting rod and the second end of the second connecting rod is adjusted, thereby adjusting the distance between the first end of the first connecting rod and the first end of the second connecting rod and the outer circumferential wall of the column, so that the distance between the spoiler arranged at the first end of the first connecting rod and the first end of the second connecting rod and the outer circumferential wall of the column increases or decreases. It can be seen that the floating column spoiler structure provided by the present invention has the following beneficial effects:

[0019] (1) When the seawater flow rate is relatively high, at least one of the first gear and the second gear is first moved to reduce the distance between the first end of the first connecting rod and the first end of the second connecting rod and the column, and the spoiler is retracted. Then, the first gear and the second gear are both moved up along the lifting gear to raise the plurality of spoilers to a preset spoiler position. Then, at least one of the first gear and the second gear is moved to increase the distance between the first end of the first connecting rod and the first end of the second connecting rod and the outer circumferential wall of the column, thereby increasing the distance between the spoiler and the outer circumferential wall of the column, and realizing the deployment function of the spoiler. The Karman vortex around the column is reduced by the plurality of deployed spoilers, and the phenomenon of vortex-induced vibration of the column is reduced, thereby reducing the inclination angle, roll angle and pitch angle of the floating wind turbine, improving the stability of the floating wind turbine, and ensuring the stable power output of the floating wind turbine.

[0020] (2) When the wind and waves are strong, at least one of the first gear and the second gear is first moved to reduce the distance between the first end of the first connecting rod and the first end of the second connecting rod and the column, and the spoiler is retracted. Then, the first gear and the second gear are both lowered along the lifting gear teeth to lower the plurality of spoilers to a preset vertical swing position, so that the center of gravity of the floating column is lowered, thereby lowering the center of gravity of the entire floating platform. Then, at least one of the first gear and the second gear is moved to increase the distance between the first end of the first connecting rod and the first end of the second connecting rod and the outer circumferential wall of the column, thereby increasing the distance between the spoiler and the outer circumferential wall of the column, and deploying the spoiler at the preset vertical swing position, thereby increasing the damping of the floating column, improving the stability of the entire floating wind turbine, and ensuring a stable power output of the floating wind turbine.

[0021] (3) When the sea is calm, at least one of the first gear and the second gear is moved to reduce the distance between the first end of the first connecting rod and the first end of the second connecting rod and the outer circumferential wall of the column, thereby reducing the distance between the spoiler and the outer circumferential wall of the column and retracting the spoiler to reduce hydrodynamics.

[0033] In view of this, the core of the present invention is to provide a floating column spoiler structure to improve the stability of the floating wind turbine.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 9 As shown, an embodiment of the present invention discloses a floating column spoiler structure, including a spoiler 100 and a lifting and deploying assembly 200.

[0036] Among them, there are multiple spoilers 100, and the lifting and deployment component 200 connects the spoiler 100 and the column 300. The lifting and deployment component 200 includes a first connecting rod 201, a second connecting rod 202, a first gear 203 and a second gear 204. The first end of the first connecting rod 201 and the first end of the second connecting rod 202 are rotatably connected, and the spoiler 100 is arranged at the first end of the first connecting rod 201 and the first end of the second connecting rod 202, the second end of the first connecting rod 201 is rotatably connected to the first gear 203, and the second end of the second connecting rod 202 is rotatably connected to the second gear 204; the first gear 203 and the second gear 204 are sequentially arranged on the outer circumferential wall of the column 300 from top to bottom along the axial direction of the column 300, and the outer circumferential wall of the column 300 is provided with lifting gear teeth that can mesh with the first gear 203 and the second gear 204.

[0037] When the floating column spoiler structure provided by the present invention is used, since the first end of the first connecting rod 201 is rotatably connected to the first end of the second connecting rod 202, the second end of the first connecting rod 201 is rotatably connected to the first gear 203, and the second end of the second connecting rod 202 is rotatably connected to the second gear 204, the first gear 203 and the second gear 204 are sequentially arranged on the outer circumferential wall of the column 300 from top to bottom along the axial direction of the column 300, and the outer circumferential wall of the column 300 is provided with lifting gear teeth that can mesh with the first gear 203 and the second gear 204; therefore, along the column 30 0 axially moves at least one of the first gear 203 and the second gear 204 to adjust the distance between the first gear 203 and the second gear 204, so that the distance between the second end of the first connecting rod 201 and the second end of the second connecting rod 202 is adjusted, so that the distance between the first end of the first connecting rod 201 and the first end of the second connecting rod 202 and the outer circumferential wall of the column 300 is adjusted, so that the distance between the spoiler 100 provided at the first end of the first connecting rod 201 and the first end of the second connecting rod 202 and the outer circumferential wall of the column 300 is increased or decreased. It can be seen that the floating column spoiler structure provided by the present invention has the following beneficial effects:

[0038] (1) When the seawater flow rate is relatively high, at least one of the first gear 203 and the second gear 204 is first moved to reduce the distance between the first end of the first connecting rod 201 and the first end of the second connecting rod 202 and the column 300, and the spoiler 100 is retracted. Then, the first gear 203 and the second gear 204 are both moved up along the lifting gear to raise the plurality of spoilers 100 to a preset spoiler position. Then, at least one of the first gear 203 and the second gear 204 is moved to increase the distance between the first end of the first connecting rod 201 and the first end of the second connecting rod 202 and the outer circumferential wall of the column 300, thereby increasing the distance between the spoiler 100 and the outer circumferential wall of the column 300, and realizing the deployment function of the spoiler 100. The Karman vortex around the column 300 is reduced by the plurality of deployed spoilers 100, and the phenomenon of vortex-induced vibration of the column 300 is reduced, thereby reducing the inclination angle, roll angle and pitch angle of the floating wind turbine, improving the stability of the floating wind turbine, and ensuring the stable power output of the floating wind turbine.

[0039] (2) When the wind and waves are strong, at least one of the first gear 203 and the second gear 204 is first moved to reduce the distance between the first end of the first connecting rod 201 and the first end of the second connecting rod 202 and the column 300, and the spoiler 100 is retracted. Then, the first gear 203 and the second gear 204 are both lowered along the lifting gear to lower the plurality of spoilers 100 to a preset heave position, thereby lowering the center of gravity of the floating column and thus the center of gravity of the entire floating platform. Then, at least one of the first gear 203 and the second gear 204 is moved to increase the distance between the first end of the first connecting rod 201 and the first end of the second connecting rod 202 and the outer circumferential wall of the column 300, thereby increasing the distance between the spoiler 100 and the outer circumferential wall of the column 300, and deploying the spoiler 100 at the preset heave position, thereby increasing the damping of the floating column, improving the stability of the entire floating wind turbine, and ensuring a stable power output of the floating wind turbine.

[0040] (3) On a calm sea, at least one of the first gear 203 and the second gear 204 is moved to reduce the distance between the first end of the first connecting rod 201 and the first end of the second connecting rod 202 and the outer circumferential wall of the column 300, thereby reducing the distance between the spoiler 100 and the outer circumferential wall of the column 300 and retracting the spoiler 100 to reduce hydrodynamic force.

[0041] It should be understood that the first connecting rod, the second connecting rod and the column section between the first gear 203 and the second gear 204 form a triangular structure. If the column section between the first gear 203 and the second gear 204 is the base of the triangular structure, the height of the triangular structure is the distance between the spoiler 100 and the column 300. When the triangular structure is a right-angled triangle, the distance between the spoiler 100 and the column 300 is the largest. When the triangular structure is an obtuse triangle, the distance between the first gear 203 and the second gear 204 is increased. The spacing between the first gear 203 and the second gear 204 can increase the distance between the spoiler 100 and the column 300. When the triangular structure is an acute triangle, reducing the spacing between the first gear 203 and the second gear 204 can increase the distance between the spoiler 100 and the column 300. Therefore, when it is necessary to realize the unfolding function of the spoiler 100, the spacing between the first gear 203 and the second gear 204 can be increased, or the spacing between the first gear 203 and the second gear 204 can be reduced, as long as the spoiler 100 can be unfolded.

[0042] In addition, the spoiler 100 can be fixedly arranged at the first end of the first connecting rod 201 and the first end of the second connecting rod 202 by means of bolt connection or rivet connection, or can be rotatably arranged at the first end of the first connecting rod 201 and the first end of the second connecting rod 202 by means of a universal joint bearing or a ball joint. As long as the connection method can meet the use requirements, it belongs to the protection scope of the present invention; optionally, the spoiler 100 provided in the embodiment of the present invention is rotatably arranged at the first end of the first connecting rod 201 and the first end of the second connecting rod 202, so that when the spoiler 100 is folded, the spoiler 100 can be rotated to fit with the outer circumferential wall of the column 300, and when the spoiler 100 is unfolded, the spoiler 100 can be rotated to form a preset inclination angle with the horizontal plane, so that the angle adjustment of the spoiler 100 is more flexible.

[0043] like Figure 1 and Figure 2 As shown, the first end of the first link 201 and the first end of the second link 202 are connected by a ball joint to achieve a rotational connection between the first end of the first link 201 and the first end of the second link 202, which is convenient for adjusting the distance between the second end of the first link 201 and the second end of the second link 202, thereby achieving the deployment and retraction of the spoiler 100.

[0044] It should be noted that the spoiler 100 may be a spoiler net, a plate-shaped member with spoiler spikes, or a spoiler with spoiler blades, etc. As long as the structure type can meet the spoiler requirements, it belongs to the protection scope of the present invention; Figure 7 As shown, in a specific embodiment of the present invention, the spoiler 100 is a spoiler net, so as to play a spoiler role through the mesh of the spoiler net. Figure 8As shown, in another specific embodiment of the present invention, the spoiler 100 includes a spoiler body and spoiler spikes arranged on the spoiler body, so as to play a spoiler role through the raised spoiler spikes.

[0045] In a specific embodiment of the present invention, the number of lifting and deploying components 200 corresponding to each spoiler 100 is three groups, and the three groups of lifting and deploying components 200 are respectively a first lifting and deploying component, a second lifting and deploying component and a third lifting and deploying component. The connection positions of the first lifting and deploying component, the second lifting and deploying component and the third lifting and deploying component and the spoiler 100 are distributed in a triangular shape to form a triangular support structure for the spoiler 100, thereby improving the stability of the spoiler 100.

[0046] In addition, the above-mentioned lifting gear teeth can be directly opened on the outer circumferential wall of the column 300, that is, the lifting gear teeth and the column 300 are an integrated structure; or, a toothed belt 301 is set on the outer circumferential wall of the column 300, and the lifting gear teeth are located on the toothed belt 301, that is, the column 300 and the toothed belt are adopted. A split structure is adopted. As long as the setting method can meet the use requirements, it belongs to the protection scope of the present invention.

[0047] Furthermore, the first gear 203 and the second gear 204 are respectively arranged on the outer circumferential wall of the column 300 through the first gear 203 mounting member and the second gear 204 mounting member, and the first gear 203 mounting member and the second gear 204 mounting member are slidably connected to the outer circumferential wall of the column 300 to realize the meshing and rolling of the first gear 203 and the second gear 204 on the lifting gear teeth, thereby adjusting the spoiler 100 to be able to be raised and lowered, as well as deployed and retracted.

[0048] In addition, the floating column spoiler structure provided by the present invention also includes a central control system, a water flow velocity monitoring system and a wind and wave environment monitoring system, as well as a first pusher for pushing the second end of the first connecting rod 201 to rise and fall and a second pusher for pushing the second end of the second connecting rod 202 to rise and fall. The central control system can transmit signals with the water flow velocity monitoring system, the wind and wave environment monitoring system, the first pusher and the second pusher, so as to monitor the seawater flow velocity information (including elements such as water flow velocity and direction) through the water flow velocity monitoring system, monitor the wave condition information (including elements such as wave height, period and wavelength) through the wind and wave environment monitoring system, and the central control system receives the seawater flow velocity information and After the wave condition information is obtained, the movement of the floating column is estimated, and according to the estimated movement of the floating column, the first pusher and the second pusher are controlled to perform the pushing action, and the first pusher and the second pusher respectively push the first connecting rod 201 and the second connecting rod 202 to adjust the height of the spoiler 100 and switch the deployment and retraction states of the spoiler 100, so that the floating column spoiler structure can actively adjust the height and state of the spoiler 100 according to the water flow velocity and the wind and wave environment, so as to better reduce the vortex-induced vibration phenomenon and improve the suppression effect of the roll and pitch of the floating wind turbine, thereby improving the stability of the floating wind turbine and ensuring the stable output of the power of the floating wind turbine.

[0049] The signal transmission method between the above-mentioned central control system and the water flow rate monitoring system, the wind and wave environment monitoring system, the first driving member and the second driving member can be wired transmission or wireless transmission. As long as the method can meet the signal transmission requirements, it belongs to the protection scope of the present invention.

[0050] In addition, the present invention also discloses a floating column and a floating wind turbine, both of which include the floating column spoiler structure as described above, and thus have all the technical effects of the floating column spoiler structure as described above, which will not be described in detail herein.

[0051] like Fig. 9 In the floating wind turbine shown, the anchor chain of the mooring system 400 fixes the column 300 on the seabed to achieve the positioning and fixation of the floating wind turbine. The floating wind turbine is set in a preset sea area to generate electricity through offshore wind energy.
