Description

Technical Field

[0001] This invention belongs to the field of wind power and relates to a connection structure for prefabricated tower sections of a wind power hybrid tower. Background Technology

[0002] In the current booming development of the wind power industry, the safety and stability of wind power equipment are of paramount importance. As a key structure supporting wind turbine generators, the connection quality of the prefabricated tower sections directly affects the load-bearing capacity and service life of the entire tower. With the development of wind power towards larger scale and higher efficiency, higher requirements are being placed on the prefabricated tower section connection structure in terms of load-bearing strength, sealing performance, and ease of installation.

[0003] Common precast tower sections for wind turbine hybrid towers are often connected using bolts, with epoxy structural adhesive or other bonding materials applied to the splicing surfaces to aid the connection. The epoxy structural adhesive utilizes its molecular-level chemical bonding properties to form chemical bonds with the hydroxyl groups on the concrete surface, enhancing bond strength. Other methods involve pre-embedding reinforcing bars during the prefabrication of segmented tower sections, then welding the reinforcing bars of adjacent sections on-site to strengthen the overall connection.

[0004] Under long-term wind loads and vibrations, bolted connections are prone to loosening, leading to decreased sealing at the connection points. This allows rainwater and dust to infiltrate, accelerating component corrosion and reducing tower stability. Furthermore, bolted connections are highly susceptible to on-site construction conditions, resulting in low construction efficiency. Additionally, bolted structures present challenges for later maintenance and disassembly. Moreover, existing connection structures struggle to achieve coordinated stress distribution among tower sections under varying stress conditions, leading to stress concentration and impacting the overall structure's load-bearing capacity and service life. Summary of the Invention

The lead screw is movably connected to the positioning plate through a bearing.

[0011] Furthermore, sliders are fixedly connected to the top and bottom of the surface of the adjustment plate, and grooves that cooperate with the sliders are opened at the top and bottom of the rear end of the positioning plate.

[0012] Furthermore, the surface of the adjustment plate is provided with a number of positioning holes, which are equidistant from each other.

[0013] Furthermore, positioning sleeves are fixedly connected to the top and bottom of one side of the positioning plate, and the positioning sleeves are provided with internal threads.

[0014] Furthermore, a first sealing strip is fixedly connected to one side of the first fixing plate, and a second sealing strip is fixedly connected to the second fixing plate, with the first sealing strip and the second sealing strip being staggered.

[0015] Furthermore, a slot is provided on the inner cavity of the limiting groove, and a card block that cooperates with the slot is fixedly connected to the upper part of the limiting block.

[0016] This invention discloses a prefabricated tower section connection structure for wind power hybrid towers, including a first fixing plate, a second fixing plate provided on one side of the first fixing plate, a positioning mechanism fixedly connected to the other side of the first fixing plate and the side of the second fixing plate, and a docking assembly fixedly connected to the top of the first fixing plate.

[0017] The docking assembly includes a first connecting plate, the bottom of which is fixedly connected to a first fixing plate.

The positioning plate and adjusting plate, through screw drive and slider / slide groove guide structures, can be flexibly fine-tuned to address construction errors, ensuring accurate connection positions and high construction efficiency.

[0040] refer to Figures 1 to 9The prefabricated tower section connection structure of the wind power hybrid tower of the present invention includes a first fixing plate 1, a second fixing plate 2 is provided on one side of the first fixing plate 1, and a positioning mechanism 3 is fixedly connected to the other side of the first fixing plate 1 and the side of the second fixing plate 2. A docking assembly 4 is fixedly connected to the top of the first fixing plate 1. The docking assembly 4 includes a first connecting plate 41, the bottom of the first connecting plate 41 is fixedly connected to the first fixing plate 1, and a snap-fit ​​block 42 is fixedly connected to the side of the first connecting plate 41. The front end and the rear end of the snap-fit ​​block 42 are provided with mounting grooves 43. Springs 44 are fixedly connected to both sides of the inner wall of the mounting groove 43. Limiting blocks 45 are fixedly connected to the springs 44. A second connecting plate 46 is fixedly connected to the top of the second fixing plate 2. A limiting plate 47 is fixedly connected to the front end and the rear end of one side of the second connecting plate 46. A limiting groove 48 is provided on one side of the limiting plate 47. The limiting groove 48 is adapted to the limiting block 45. A fastening mechanism 49 is provided through the first connecting plate 41 and the second connecting plate 46.

[0041] The positioning plate 31 is securely connected to the first fixing plate 1 and the second fixing plate 2 via chemical anchoring. The groove 6 on the surface of the positioning plate 31 has a dovetail groove structure, forming a sliding pair with the slider 5 at the bottom of the adjusting plate 32, enabling smooth sliding of the adjusting plate 32. The end of the lead screw 33 is movably connected to the positioning plate 31 via a bearing. Rotating the lead screw 33 drives the adjusting plate 32 to move along the direction of the groove 6. The positioning holes 7 evenly distributed on the surface of the adjusting plate 32 cooperate with the positioning sleeves 8 on the positioning plate 31, achieving precise positioning and fastening through high-strength bolts. The spring 44 in the mounting groove 43 has good elasticity and fatigue resistance. To ensure that the limiting block 45 maintains a stable clamping force during long-term use, the head of the limiting block 45 is designed with a chamfered structure for easy and quick insertion into the limiting groove 48. The dimensions of the limiting groove 48 are precisely matched with the limiting block 45 to ensure docking accuracy. The fixed anchor rod 491 is made of high-strength precision-rolled threaded steel bar, which has excellent tensile strength and fatigue resistance. The baffle 492 is movably connected to the fixed anchor rod 491 through a rotating shaft, and the angle can be flexibly adjusted to adapt to different installation requirements. The fastener 493 uses a matching precision-rolled nut to form a reliable threaded connection with the fixed anchor rod 491, ensuring the tightness and stability of the connection.

[0042] The design of the sliding groove 6 and the slider 5 ensures smooth sliding and precise positioning of the adjusting plate 32, effectively improving the installation accuracy and reliability of the positioning mechanism 3. The structure of the lead screw 33 driving the adjusting plate 32 allows for flexible adjustment of the connection position, adapting to installation requirements under different working conditions. The design of the locking block 42 and the limiting plate 47, driven by the spring 44, allows the limiting block 45 to engage with the limiting groove 48, achieving rapid docking and initial fixation, simplifying the installation process. The chamfered structure at the head of the limiting block 45 reduces the guiding resistance during docking, making the docking operation more convenient and efficient.

[0043] The fastening mechanism 49 includes a fixed anchor rod 491, which is disposed between the first connecting plate 41 and the second connecting plate 46. One side of the fixed anchor rod 491 is movably connected to a baffle 492 via a rotating shaft, and the other side of the fixed anchor rod 491 is threadedly connected to a fastener 493. The fixed anchor rod 491 passes through the first connecting plate 41 and the second connecting plate 46, and forms a two-way constraint through the baffle 492 and the fastener 493. It can adjust the angle through the rotating shaft to adapt to different installation requirements, and can provide a stable preload through the threaded connection to ensure that the connection does not loosen under long-term vibration. The fixed anchor rod 491 cooperates with the docking assembly 4 to make the first fixed plate 1 and the second fixed plate 2 form a whole when under force, which effectively improves stress distribution, reduces local stress concentration, and improves the load-bearing capacity and fatigue resistance of the structure.

[0044] The positioning mechanism 3 includes a positioning plate 31. One side of the positioning plate 31 is fixedly connected to the first fixed plate 1 and the second fixed plate 2 respectively. The other side of the positioning plate 31 is slidably connected to an adjusting plate 32. A lead screw 33 is provided through the adjusting plate 32. The lead screw 33 is movably connected to the positioning plate 31 through a bearing. The sliding connection design between the positioning plate 31 and the adjusting plate 32, driven by the lead screw 33, enables fine-tuning of the position, which can adapt to different construction errors and terrain changes, and improve the installation accuracy and adaptability of the connection structure.

[0045] The top and bottom of the adjusting plate 32 are fixedly connected with sliders 5. The top and bottom of the rear end of the positioning plate 31 are provided with slide grooves 6 that cooperate with sliders 5. The sliders 5 cooperate with slide grooves 6 to limit the movement direction of the adjusting plate 32, ensure the smooth transmission of load in the positioning mechanism 3, and enhance the overall rigidity and stability of the connection part.

[0046] A number of positioning holes 7 are provided on one side of the surface of the adjusting plate 32. The positioning holes 7 are equidistant from each other. The positioning holes 7 are fixed with high-strength bolts, so that the adjusting plate 32 can be quickly and accurately locked in position after adjustment, reducing construction time and errors and improving installation efficiency.

[0047] Positioning sleeves 8 are fixedly connected to the top and bottom of one side of the positioning plate 31. The positioning sleeves 8 have internal threads. The internal thread design of the positioning sleeves 8 forms a mechanical engagement with the high-strength bolts, effectively resisting tensile and shear forces, enhancing the connection strength between the positioning mechanism 3 and the tower section, and preventing displacement or loosening under wind loads.

[0048] A first sealing strip 9 is fixedly connected to one side of the first fixing plate 1, and a second sealing strip 10 is fixedly connected to one side of the second fixing plate 2. The first sealing strip 9 and the second sealing strip 10 are staggered. The staggered arrangement of the first sealing strip 9 and the second sealing strip 10 forms a sealing structure at the splicing surface, effectively blocking the intrusion of rainwater, sand and dust, protecting the internal connecting parts from corrosion, and extending the service life of the structure. The elastic design of the sealing strip can adapt to the slight deformation of the tower section under load, maintain the stability of the sealing performance, and ensure that the sealing effect does not decrease during long-term use.

[0049] A slot 11 is provided on one side of the inner cavity of the limiting groove 48, and a locking block 12 that cooperates with the slot 11 is fixedly connected to one side of the limiting block 45. The cooperation between the slot 11 and the locking block 12 forms a secondary lock between the limiting block 45 and the limiting groove 48, preventing the limiting block 45 from accidentally coming off due to vibration or wind load, thereby improving the reliability and safety of the docking assembly 4. The increased contact area between the locking block 12 and the slot 11 makes the load distribution more uniform, reduces local stress concentration, and extends the fatigue life of the connection part.

[0050] Mounting blocks are fixedly connected to one side of the first connecting plate 41 and one side of the second connecting plate 46. The bottom of the mounting blocks is fixedly connected to the first fixing plate 1 and the second fixing plate 2 respectively by bolts. The combination of mounting blocks and bolts forms a detachable connection between the first connecting plate 41, the second connecting plate 46 and the fixing plate, which facilitates factory prefabrication and on-site assembly and shortens the construction cycle.

[0051] A mounting hole is provided on one side of the snap-fit ​​block 42, and one side of the fixing anchor rod 491 passes through the inner cavity of the mounting hole. The fixing anchor rod 491 passes through the mounting hole of the snap-fit ​​block 42, so that the docking assembly 4 and the fastening mechanism 49 form a continuous force transmission path, ensuring that the load is smoothly transferred from one tower section to another, and improving the mechanical performance of the overall structure.

[0052] The working principle of this invention is as follows:

[0053] Due to construction errors caused by different installation environments, the adjusting plate 32 is driven by rotating the lead screw 33. The slider 5 at the bottom of the adjusting plate 32 slides smoothly along the groove 6 on the surface of the positioning plate 31, achieving fine-tuning of the position. When the adjusting plate 32 moves to the appropriate position, the high-strength bolt is passed through the positioning hole 7 and the positioning sleeve 8 to precisely lock the adjusting plate 32 and the positioning plate 31. During installation, the first fixing plate 1 and the second fixing plate 2 are brought close together, and the limiting block 45 of the locking block 42 on the first connecting plate 41 and the limiting block 47 of the upper plate 47 on the second connecting plate 46 are engaged. With the slots 48 aligned, and the head of the limiting block 45 designed with a chamfered structure, when the two are close together, the limiting block 45 can smoothly enter the limiting slot 48 under the guidance. As they get closer, the spring 44 is compressed. When the limiting block 45 is fully inside the limiting slot 48, it pushes the limiting block 45 to be tightly locked into the limiting slot 48. After the limiting block 45 is locked into the limiting slot 48, the locking block 12 is further locked into the locking groove 11, forming a secondary lock. This achieves the initial and rapid docking of the first fixing plate 1 and the second fixing plate 2, greatly simplifying the installation process and reducing the difficulty of docking.

[0054] After the initial docking is completed, the fixed anchor rod 491 passes through the mounting holes of the first connecting plate 41, the snap-fit ​​block 42, and the second connecting plate 46. On one side of the fixed anchor rod 491, the baffle 492 rotates flexibly through the shaft and fits against the surface of the first connecting plate 41. On the other side, the matching nut is threaded to the fixed anchor rod 491 and tightened. The baffle 492 and the fastener 493 form a bidirectional constraint, providing a stable preload for the connection. Under long-term wind vibration, the high-strength fixed anchor rod 491 cooperates with the docking assembly 4 to make the first fixed plate 1 and the second fixed plate 2 form a whole when under force, effectively improving stress distribution, reducing local stress concentration, significantly improving the load-bearing capacity and fatigue resistance of the connection structure, and ensuring that the connection is stable and does not loosen for a long time.

[0055] The first sealing strip 9 and the second sealing strip 10, which are interleaved on the first fixing plate 1 and the second fixing plate 2, form a tight sealing structure after the first fixing plate 1 and the second fixing plate 2 are mated together. These sealing strips are elastic and can adapt to the slight deformation of the tower section under wind load, effectively blocking the intrusion of external pollutants such as rainwater and sand, protecting the internal connecting parts from corrosion, and thus extending the service life of the connecting structure.
