Description

Technical Field

[0001] This invention relates to the field of offshore wind turbine construction technology, specifically a six-tube tower structure for wind turbines. Background Technology

[0002] Offshore wind turbines are the core power generation devices used in offshore wind power. They mainly consist of wind turbine generators, towers, support structures, and foundations. They generate lift through blade aerodynamics to drive the generator and convert wind energy into electrical energy. As the core equipment of offshore wind power, offshore wind turbines are developing towards larger scale, intelligence, and deep-sea applications. Their technological innovation and application promotion are of great significance for promoting global energy transformation and sustainable development.

[0003] Currently, during the installation of offshore wind turbines, the tower is hoisted onto the mounting base already installed on the pier, and then the tower is connected to the mounting base. Due to the influence of wind and waves on the sea surface, the hoisting vessel and the tower sway. If the tower is not aligned with the swaying tower and its surrounding components during the connection and installation with the mounting base, it may collide with the mounting base and its surrounding components. The huge impact force may damage the components.

[0004] Patent CN118669271B discloses a combined tower structure for wind turbines. In the transport state, each connecting steel pipe is retracted into its corresponding supporting steel pipe; in the installation state, each connecting steel pipe extends from its respective supporting steel pipe, with the lower end of each connecting steel pipe corresponding to the upper end of its respective supporting steel pipe. This solves the problems of inconvenient transportation and high transportation costs associated with existing wind turbine tower support components. However, the above solution is inconvenient for quickly aligning the hoisted tower with the mounting base. In offshore wind turbine installation, the sea-based support platform is installed first, and then the tower is hoisted onto the mounting base. Due to strong winds and swells at sea, the hoisting vessel sways, causing the hoisted tower to sway during installation. This prevents the tower from quickly aligning with the mounting base, making the installation process significantly affected by wind and waves and time-consuming. Therefore, a six-tube tower structure for wind turbines is proposed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and propose a six-tube tower structure for wind turbines. This device uses the first and second conical semi-cylinders to assist in the adjustment and positioning of the second hydraulic buffer cylinder, making it easier and faster to align the hoisted tower with the mounting base, thereby reducing the tower installation time and improving efficiency. Furthermore, the second hydraulic buffer cylinder can play a buffering role during the installation process, while the first hydraulic buffer cylinder buffers the second conical semi-cylinder, preventing the impact force generated by shaking during installation from causing damage to components.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a six-tube tower structure for wind turbine generators, comprising an underwater six-tube tower, a support platform fixed at the top of the underwater six-tube tower, six suction anchors arranged in a circle fixed at the bottom of the underwater six-tube tower, an offshore wind turbine generator set disposed above the underwater six-tube tower, the offshore wind turbine generator set comprising a mounting base fixed to the upper surface of the support platform, and a tower tube mounted on the top of the mounting base.

[0007] The underwater six-tube tower is equipped with six adjustment components arranged in a circle above it. Each adjustment component includes a support platform, a large gear rotatably connected to the upper surface of the support platform, a first conical semi-cylinder fixed to the upper surface of the large gear, and a second conical semi-cylinder hinged to the upper surface of the large gear.

[0008] The outer surface of the first conical semi-cylinder is hinged with two symmetrical snap-fit ​​brackets, and the outer surface of the second conical semi-cylinder is fixed with two symmetrical snap-fit ​​seats. The two snap-fit ​​brackets are respectively adapted to the two snap-fit ​​seats.

[0009] The underwater six-tube tower is equipped with six positioning components arranged in a circular array. Each positioning component includes a connecting frame, and a second hydraulic buffer cylinder is fixed to the bottom surface of the connecting frame. Both the first conical half-cylinder and the second conical half-cylinder are adapted to the second hydraulic buffer cylinder.

[0010] Furthermore, a wind turbine is installed at the top of the tower, a mounting ring is fixed to the inner wall of the tower, and multiple mounting bolts arranged in a circular pattern are fixed to the top of the mounting base. Each mounting bolt is adapted to the mounting ring. Inserting the mounting bolts into the mounting ring and tightening them securely connects the mounting base and the tower.

[0011] Furthermore, a fixed frame is fixed to the upper surface of the large gear, and a threaded rod is rotatably connected to the inner wall of the fixed frame. A first motor is fixed to the upper surface of the large gear, and one end of the threaded rod near the first motor is fixed to the output shaft end of the first motor. An internal threaded slider is threadedly connected to the outer surface of the threaded rod. The internal threaded slider is slidably connected to the inner wall of the fixed frame. A first hydraulic buffer cylinder is hinged to the upper surface of the internal threaded slider, and the top end of the first hydraulic buffer cylinder is hinged to the outer surface of the second conical semi-cylinder.

[0012] By adopting the above technical solution, when the position of the internal thread slider remains unchanged, the first hydraulic buffer cylinder can buffer the second conical half-cylinder when it rotates under force. At the same time, when the internal thread slider moves and the position of the second conical half-cylinder remains unchanged, the hydraulic pressure inside the first hydraulic buffer cylinder can be adjusted.

[0013] Furthermore, a support frame is fixed to the outer surface of the first conical semi-cylinder, an electric push rod is fixed to the inner wall of the support frame, a sliding frame is fixed to the telescopic end of the electric push rod, and a fixing rod is fixed to the inner wall of both snap-fit ​​frames, and both fixing rods are slidably connected to the inner wall of the sliding frame.

[0014] By adopting the above technical solution, the sliding frame can be moved by pushing the snap-fit ​​frame to unfold or retract through the fixed rod.

[0015] Furthermore, two guide rods are fixed to the outer surface of the first conical semi-cylinder. The ends of the two guide rods away from the first conical semi-cylinder are both fixed to the outer surface of the support frame. Both guide rods pass through the sliding frame and are slidably connected to the sliding frame. The guide rods serve to assist in guiding the movement of the sliding frame.

[0016] Furthermore, a second motor is fixed to the upper surface of the support platform, and the output shaft of the second motor is rotatably connected to the upper surface of the support platform. A small gear is fixed to the outer surface of the output shaft of the second motor, and the small gear meshes with the large gear.

[0017] In the above technical solution, when the second motor is running, it drives the large gear to rotate through the small gear, so as to adjust the position of the second conical half-cylinder so that it can first contact the second hydraulic buffer cylinder.

[0018] Furthermore, a first arc-shaped frame is fixed to the outer surface of the support platform, and two symmetrical first flanges are fixed to the outer surface of the first arc-shaped frame. Three support piles are fixed to the bottom surface of the support platform. The support platform can be installed on the bearing platform through the support piles.

[0019] Furthermore, a hydraulic rod is fixed to the inner wall of the connecting frame, and a bonding plate is fixed to the telescopic end of the hydraulic rod. The bonding plate is adapted to the tower. By clamping the tower with multiple bonding plates, multiple connecting frames are fixed to the outside of the tower.

[0020] Furthermore, a first sliding rod is fixed to the outer surface of the bonding plate. The first sliding rod is slidably connected to the inner wall of the connecting frame. A first fastening screw is threaded onto the inner wall of the connecting frame, and the first fastening screw is adapted to the first sliding rod. A second sliding rod is fixed to the outer surface of the bonding plate. A guide seat is slidably connected to the outer surface of the second sliding rod. The guide seat is fixed to the outer surface of the connecting frame. A second fastening screw is threaded onto the inner wall of the guide seat, and the second fastening screw is adapted to the second sliding rod. By fixing the second sliding rod with the second fastening screw and fixing the first sliding rod with the first fastening screw, the position of the bonding plate is fixed.

[0021] Furthermore, a second arc-shaped frame is fixed to the outer surface of the connecting frame, and two symmetrical second flanges are fixed to the outer surface of the second arc-shaped frame. A third arc-shaped frame is fixed to the outer surface of the connecting frame, and two symmetrical third flanges are fixed to the outer surface of the third arc-shaped frame. Two symmetrical crossbeams are fixed to the outer surface of the connecting frame, and a fourth flange is fixed to the end of each of the two crossbeams away from the underwater six-tube tower. The two adjacent connecting frames are connected and fixed by the connection and installation of the two fourth flanges, the two third flanges, and the two second flanges.

[0022] Compared with existing technologies, this six-tube tower structure for wind turbines has the following advantages: I. By adjusting and positioning the components, this invention enables the tower to be aligned with the mounting base more easily and quickly when it is hoisted and installed onto the mounting base. This is achieved by using the first and second conical half-cylinders to assist in the adjustment and positioning of the second hydraulic buffer cylinder. This avoids the impact of wind and waves on the installation of the tower caused by the swaying of the hoisting vessel and the tower, thereby reducing the installation time and improving efficiency.

[0023] II. By setting up a second hydraulic buffer cylinder and a first hydraulic buffer cylinder, when the tower is hoisted and installed on the mounting base, the second hydraulic buffer cylinder first contacts the first or second conical half-cylinder. The second hydraulic buffer cylinder can play a buffering role. When the second hydraulic buffer cylinder contacts the second conical half-cylinder, the pressure pushes the second conical half-cylinder to rotate and applies pressure to the first hydraulic buffer cylinder. The first hydraulic buffer cylinder buffers the second conical half-cylinder, avoiding damage to the components caused by the impact force generated by shaking during installation.

[0024] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0040] Working principle: First, the underwater six-tube tower 1 is hoisted to a suitable position at sea, so that the suction anchor 12 is located on the seabed. By extracting the air inside the suction anchor 12 to create negative pressure, the suction anchor 12 is inserted into the seabed. Multiple support platforms 31 are installed on the bearing platform 11 through support piles 321 and connected by two adjacent first flanges 320 to fix the support platforms 31 to the outside of the mounting base 21. Then, multiple connecting frames 41 are fixed to the outside of the tower 22 by connecting two adjacent second flanges 411, two adjacent third flanges 413 and two adjacent fourth flanges 415. By controlling the extension of the hydraulic rod 43, multiple bonding plates 44 are clamped and fixed to the tower 22, and the corresponding first fastening screws 46 and second fastening screws 49 are tightened. At this point, the tower cylinder 22 is hoisted to the top of the mounting base 21 by a hoisting vessel. First, the hoisting position is adjusted so that the tower cylinder 22 is positioned directly above the mounting base 21 as much as possible. Then, the second motor 317 is controlled to operate, which drives the large gear 32 to rotate through the small gear 318, so that multiple second conical semi-cylinders 34 are positioned below the second hydraulic buffer cylinder 42. At the same time, the electric push rod 311 is controlled to extend, causing the two clamping brackets 313 to unfold and move away from the clamping seat 315. Then, the tower cylinder 22 is slowly lowered. The second hydraulic buffer cylinder 42 first engages with the second conical semi-cylinders 313. 4. Upon contact, the second hydraulic buffer cylinder 42 is compressed and the second conical half-cylinder 34 tilts and compresses the first hydraulic buffer cylinder 35. At this time, the first motor 39 is controlled to operate, driving the threaded rod 38 to rotate and causing the internal threaded slider 36 to move closer to the second conical half-cylinder 34. The oil pressure inside the first hydraulic buffer cylinder 35 increases and pushes the second conical half-cylinder 34 to move until it is vertical. Under the force of the second conical half-cylinder 34, the second hydraulic buffer cylinder 42 is adjusted to a position and approaches the exact middle position of the first conical half-cylinder 33 and the second conical half-cylinder 34. Then, the electric push rod 311 is shortened, causing the two snap-fit ​​brackets 313 to retract and fasten onto the snap-fit ​​seat 315, ensuring the connection and fixation of the first conical half-cylinder 33 and the second conical half-cylinder 34. The tower cylinder 22 is then slowly lowered. Under the action of the funnel-shaped inner wall formed by the first conical half-cylinder 33 and the second conical half-cylinder 34, and the second hydraulic buffer cylinder 42, the second hydraulic buffer cylinder 42 is adjusted again towards the exact center of the first conical half-cylinder 33 and the second conical half-cylinder 34 until it is positioned precisely in the center. At this point, the lower tower cylinder 22 and the second hydraulic buffer cylinder 42... Insert the first conical half-cylinder 33 and the second conical half-cylinder 34 into the cylindrical inner wall of the lower half. At this time, the tower 22 is aligned with the mounting base 21, and the mounting bolt 25 is inserted into the mounting ring 24 for fastening. After installation, the support platform 31 is removed from the outside of the mounting base 21, and the connecting frame 41 is removed from the outside of the tower 22. This device makes it easier and faster to align the hoisted tower 22 with the mounting base 21, thereby reducing the installation time of the tower 22 and improving efficiency. In addition, the first hydraulic buffer cylinder 35 and the second hydraulic buffer cylinder 42 can play a buffering role during the installation process, avoiding the impact force generated by shaking during installation that could damage the components.
