DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0040] In the related art, the foundation of an offshore wind turbine includes a duct frame 1 and a tower frame 3. The tower frame 3 is fixed on the top of the duct frame 1. At present, in addition to bearing the wind load and the excitation generated by the rotation of the wind rotor, the tower frame 3 of the offshore wind turbine may also be affected by wave loads during large waves. The complex external environment may cause uneven force, fatigue damage, or even structural damage to the connection between the tower frame 3 and the duct frame 1, thereby affecting the normal operation of the wind turbine. At the same time, the salt, humidity, and attachment of marine organisms in the marine environment will also aggravate the corrosion and damage of the connection between the tower frame and the supporting structure. However, in the prior art, when installing offshore wind turbines, in order to save costs and facilitate transportation, bolts and welded rods are usually used for support. This connection method often has a limited service life and often requires maintenance.

[0041] This embodiment provides a jacket foundation tower support structure, which can solve the problems of uneven force, fatigue damage and even structural destruction of offshore wind turbine tower structures in the prior art. Compared with support only by bolts and welded rods, it has stronger stability and longer service life.

[0042] like Figure 1-Figure 4 As shown, a tower 3 is fixed on the top of the conductor frame 1, and the conductor frame 1 is a rectangular frame structure. In order to ensure that the tower 3 maintains stability relative to the conductor frame 1, this embodiment provides a conductor frame basic tower support structure, including a first enclosing ring 4, a stabilizing plate 2, 4 groups of pulleys, 4 groups of second fixing members and 4 groups of steel cables 5.

[0043] The first enclosing ring 4 is fixedly connected to the middle outer wall of the tower 3, and the outer wall of the first enclosing ring 4 is provided with four groups of evenly distributed first fixing members 33;

[0044] The stabilizing plate 2 is fixed in the catheter frame 1, and 4 groups of through holes 7 are provided on the stabilizing plate 2, and the 4 groups of through holes are evenly distributed around the stabilizing plate;

[0045] 4 sets of pulleys 6, the pulleys 6 are rotatably connected to the top outer wall of the catheter frame 1;

[0046] 4 sets of second fixing members, the second fixing members include a connecting block 9, a pressure plate 11 and an upper lifting column 12, the pressure plate 11 is arranged at the bottom of the connecting block 9 and the pressure plate 11 and the connecting block 9 are connected by at least one stable supporting mechanism, the connecting block 9 is fixed to the bottom of the through hole 7, the upper lifting column 12 is slidably connected to the connecting block 9, and the upper lifting column 12 is in the first position or the second position, and the radius of the upper lifting column 12 is greater than the radius of the through hole 7;

[0047] When the lifting column 12 is in the first position, the bottom of the lifting column 12 abuts against the top of the pressure plate 11;

[0048] When the lifting column 12 is in the second position, the top of the lifting column 12 abuts against the bottom of the stabilizing plate 2;

[0049] There are 4 groups of steel cables 5, one end of each steel cable 5 is fixed to the first fixing member 33, the middle part passes around the pulley 6 and the other end passes through the through hole 7 and is fixedly connected to the upper lifting column 12 to make the steel cable 5 V-shaped, and each steel cable 5 maintains the connection tension of the steel cable 5 through at least one stable supporting mechanism, and the number of the first fixing member 33, the through hole 7, the pulley 6, the second fixing member and the steel cable 5 is consistent.

[0050] The present embodiment provides a guide tube frame foundation tower support structure. In the initial state, the upper lifting column 12 is in the first position, and the bottom of the upper lifting column 12 abuts against the top of the pressure plate 11. When the tower 3 shakes or deflects, the upper lifting column 12 slides relative to the connecting block 9, which will give the steel cable 5 a certain upward movement distance. Since the radius of the upper lifting column 12 is greater than the radius of the through hole 7, the lifting column is in the second position, and the top of the upper lifting column 12 abuts against the bottom of the stabilizing plate 2, so that the steel cable 5 supports the shaking tower 3. In the present embodiment, each steel cable 5 maintains the connection tension of the steel cable 5 through at least one stable support mechanism to further ensure that the steel cable 5 supports the shaking tower 3. When the tower 3 stops shaking, the upper lifting column 12 slides relative to the connecting block 9, which will give the steel cable 5 a certain downward movement distance, so that the upper lifting column 12 returns to the first position, and the bottom of the upper lifting column 12 abuts against the top of the pressure plate 11. The present embodiment can effectively improve the connection stability between the wind turbine and the guide tube frame during use to achieve buffer protection.

[0051] In the present embodiment, since the conductor frame 1 is a rectangular frame structure, in order to ensure that the tower frame 3 maintains stability in the four directions of front, back, left, and right relative to the conductor frame 1, the present embodiment forms a supporting structure in four directions through four groups of first fixing members 33, four groups of through holes 7, four groups of through holes, four groups of pulleys, four groups of second fixing members, and four groups of steel cables 5, so as to protect the tower frame 3 in the four directions of front, back, left, and right relative to the conductor frame 1, prevent the tower frame 3 from tilting in any direction, and greatly improve the stability of the tower frame 3 relative to the conductor frame 1.

[0052] In this embodiment, Figure 1-Figure 4 As shown, the stable support mechanism includes a driving rod 13, a first elastic member 14, a shaft 29, a lifting plate 15, a resistance rod 16, a locking rod 20, a cylinder body 17 and a second elastic member 19. The bottom of the driving rod 13 is fixed to the top of the pressure plate 11, the first elastic member 14 is arranged at the top of the driving rod 13, the locking rod 20 is fixed to the connecting block 9, the cylinder body 17 is fixed to the locking rod 20, the cylinder body 17 has a sliding cavity, a piston 18 is arranged at the bottom of the resistance rod 16, the piston 18 is slidably connected to the sliding cavity, the second elastic member 19 is sleeved on the resistance rod 16, the shaft 29 is fixedly connected to the connecting block 9 and is arranged between the driving rod 13 and the resistance rod 16, the middle part of the lifting plate 15 is rotatably connected to the shaft 29, and one end of the lifting plate 15 abuts against the top of the driving rod 13, and the other end abuts against the top of the resistance rod 16.

[0053] During use, the tower 3 is easily shaken by waves and strong winds, which causes metal fatigue at the connection between the pipe frame 1 and the tower 3, affecting the service life. Therefore, after the tower 3 is built, a stable support mechanism needs to be installed to strengthen the connection between the tower 3 and the pipe frame 1. First, it is fixed to the middle part of the outer wall of the top of the tower 3 through the first enclosing ring 4, and then the steel cables 5 in multiple directions are pulled through the through hole 7 to enter the bottom of the stabilizing plate 2, and connected with the upper lifting column 12 after entering. When the tower 3 shakes or deflects, the steel cables 5 at the corresponding angles will pull the upper lifting column 12 to drive the pressure plate 11 to move upward, and after moving upward, drive the connected driving rod 13 to compress the first elastic member 14. The first elastic member 14 can increase the damping of the displacement of the driving rod 13, and in the process of damping improvement, by giving an upward rising pressure to one side of the lifting plate 15, the lifting plate 15 realizes the lever principle through the setting of the shaft 29, so that the lifting plate 15 at the other end presses down the resistance rod 16, and a piston 18 is installed on one side of the resistance rod 16. The buffering effect brought by the second elastic member 19 and the compressed air in the cylinder 17 is used to improve the stability of the overall connection, and the connection tension of the steel cable 5 is maintained by the use of the cylinder 17 and the piston 18.

[0054] In this embodiment, if Figure 1-Figure 4 As shown, the number of each group of first fixing members 33, through holes 7, pulleys 6, second fixing members and steel cables 5 is 1 to 3.

[0055] In this embodiment, if Figure 1-Figure 4 As shown, the conductor frame 1 is usually a centrally symmetrical structure, and the tower frame 3 is arranged in the middle of the conductor frame 1. In order to ensure that all positions where the conductor frame 1 is connected to the tower frame 3 remain balanced, the first enclosing ring 4 is sleeved on the tower frame 3 and fixed to the tower frame 3. A plurality of groups of first fixing members 33 are centrally symmetrically distributed relative to the tower frame 3, and each group of first fixing members 33 includes 1 to 3 first fixing members 33. Correspondingly, the steel cables 5 also include a plurality of groups, and each group of steel cables 5 includes 1 to 3 steel cables 5; the through holes 7 also include a plurality of groups, and each group of through holes 7 includes 1 to 3 through holes 7, and the number of first fixing members 33, steel cables 5 and through holes 7 is consistent.

[0056] In this embodiment, the first elastic member 14 and the second elastic member 19 are both springs.

[0057] In this embodiment, Figure 8 As shown, the stable support mechanism further includes a buffer box 30, which is fixed to the middle of the top of the stabilizing plate 2, and the plurality of through holes 7 are centrally symmetrically distributed relative to the buffer box 30. By providing the stabilizing box, the tower 3 is further ensured to be stable relative to the pipe frame 1.

[0058] In this embodiment, glycerin is provided in the buffer box 23. The density of glycerin is higher than that of seawater, so the buffer pressure relief capacity can be effectively improved. The glycerin filled in the buffer box 23 can reduce the shaking of the pipe frame 1 within a certain range through its high density.

[0059] In this embodiment, in order to enhance the stable support provided by the stable support mechanism between the conductor frame 1 and the tower frame 3, a plurality of groups of pulleys 6 are arranged on the outer wall of the conductor frame 1, each group of pulleys 6 includes at least one pulley 6, and the pulleys 6 are rotatably connected to the conductor frame 1. Each steel cable 5 is slidably connected to a pulley 6, so that the movement of the steel cable 5 is smoother. When the tower frame 3 shakes or deviates, the steel cable 5 can more easily lift the lifting column 12.

[0060] In this embodiment, in order to limit the moving direction of the upper lifting column 12, a limiting tube 10 is fixed in the connecting block 9. The limiting tube 10 has a sliding cavity in the vertical direction, and the upper lifting column 12 is slidably connected to the sliding cavity.

[0061] In this embodiment, Figure 5-Figure 7As shown, in order to further improve the stability between the conductor frame 1 and the tower frame 3, an anti-torque mechanism is also included, and the anti-torque mechanism includes a torque ring 21, and the torque ring 21 is fixedly connected to the bottom of the outer wall of the tower frame 3. An anti-torque component is arranged on the torque ring 21, and the anti-torque component includes an extension part, a telescopic frame, a push plate 24, a positioning box 25 and a damper 26. The extension part is fixedly connected to the outer wall of the torque ring 21, the telescopic frame is arranged on the extension part, the push plate 24 is rotatably connected to the telescopic frame, the positioning box 25 is fixedly connected to the conductor frame 1, and the inner wall of the positioning box 25 is fixedly connected with the damper 26, and a third elastic member 27 is arranged on the push plate 24, and the third elastic member 27 is sleeved on the output shaft of the damper 26.

[0062] In this embodiment, when the tower 3 is subjected to lateral pressure and torque pressure is generated, the pressure is transmitted to the push plate 24 through the telescopic frame under the drive of the torque ring 21, that is, the push plate 24 is pushed to move toward the inside of the positioning box 25, and a damper 26 and a third elastic member 27 are arranged inside the positioning box 25. The setting of the damper 26 and the third elastic member 27 is sufficient to buffer the torque pressure generated at the connection between the tower 3 and the catheter frame 1.

[0063] In this embodiment, Figure 5 and Figure 6 As shown, in order to further ensure that each position where the pipe frame 1 is connected to the tower frame 3 is balanced, the torque ring 21 is sleeved on the tower frame 3 and fixed to the tower frame 3, and the multiple groups of first fixing members 33 are distributed symmetrically with respect to the tower frame 3.

[0064] Specifically, Figure 7 As shown, the extension portion includes two relatively arranged extension plates 22, and the telescopic frame includes a first connecting rod 31 and a second connecting rod 32. The first connecting rod 31 and the second connecting rod 32, one end of the first connecting rod 31 is rotatably connected to one of the extension plates 22, and the other end is rotatably connected to the push plate 24, one end of the second connecting rod 32 is rotatably connected to the other extension plate 22, and the other end is rotatably connected to the push plate 24, the first connecting rod 31 and the second connecting rod 32 are cross-arranged and the middle parts of the first connecting rod 31 and the second connecting rod 31 are hinged.

[0065] In this embodiment, the third elastic member 27 is a spring.

[0066] In this embodiment, Figure 8 As shown, the sealing assembly also includes a self-rotating bolt 28 and a sealing box 8. The sealing box 8 is slidably connected to the bottom of the stabilizing plate 2 and covers the second fixing member and the stabilizing support mechanism. The sealing box 8 and the stabilizing plate 2 are locked by a plurality of self-rotating bolts 28 to seal the second fixing member and the stabilizing support mechanism. In order to facilitate daily maintenance and reduce the corrosion of the stabilizing support mechanism by seawater, the sealing box 8 can be installed by rotating the self-rotating bolt 28, thereby forming protection and facilitating maintenance operations for the staff.

[0067] In this embodiment, the sealing box 8 is threadedly connected to the outer wall of the plurality of self-rotating bolts 28 .

[0068] In summary, this embodiment has the following working principles:

[0069] When installing the jacket foundation tower support structure, the jacket 1 is first installed on the top of the designated seabed, and then the tower 3 is installed and fixed on the top of the jacket 1.

[0070] After installation, the tower 3 is easily shaken by waves and strong winds, which may cause metal fatigue at the connection between the pipe frame 1 and the tower 3, thus affecting the service life. Therefore, after the tower 3 is built, a stable support mechanism needs to be installed to strengthen the connection between the tower 3 and the pipe frame 1. First, it is fixed to the middle part of the outer wall of the tower 3 through the first enclosing ring 4, and then the steel cables 5 in multiple directions are pulled through the restriction of the pulley 6 and enter the bottom of the stabilizing plate 2 through the through hole 7, and are connected with the upper lifting column 12 after entering. When the tower 3 shakes or deflects, the steel cables 5 at the corresponding angles will pull the upper lifting column 12 through the limit of the limit tube 10 to drive the pressure plate 11 to move upward, and after moving upward, drive multiple connected driving rods 13 to compress the first elastic member 14, and the first elastic member 14 can increase the damping of the displacement of the driving rod 13, and in the process of damping improvement, by giving an upward rising pressure to one side of the lifting plate 15, the lifting plate 15 realizes the lever principle through the setting of the shaft 29, so that the lifting plate 15 at the other end presses down the resistance rod, and a piston 18 is installed on one side of the resistance rod, and the buffering effect brought by the second elastic member 19 and the compressed air in the cylinder 17 is used to improve the stability of the overall connection, and the steel cable connection tension is maintained by the use of the cylinder 17 and the piston 18.

[0071] At the same time, since the tower 3 may be subjected to wind loads from different directions, in order to reduce the metal fatigue caused by long-term torque overload at the connection between the tower 3 and the catheter frame 1, a torque ring 21 can be installed on the upper side of the connection between the tower 3 and the catheter frame 1. When the tower 3 is subjected to lateral pressure to generate torque pressure, the pressure is transmitted to the push plate 24 through the telescopic frame under the drive of the torque ring 21, that is, the push plate 24 will be pushed to move toward the inside of the positioning box 25, and a damper 26 and a third elastic member 27 are arranged inside the positioning box 25. The setting of the damper 26 and the third elastic member 27 is sufficient to buffer the torque pressure generated at the connection between the tower 3 and the catheter frame 1.

[0072] With the stable support mechanism, the glycerin filled in the buffer box 30 reduces the shaking of the pipe frame 1 within a certain range due to its high density. In order to facilitate daily maintenance and reduce the corrosion of the stable support mechanism by seawater, the sealing box can be installed by rotating the rotating bolt 28, thereby forming protection and facilitating maintenance operations for the staff.

[0073] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
