Description
Technical Field
[0001] This utility model relates to the field of tower technology, and in particular to a tower with multiple anti-corrosion structures. Background Technology
[0002] The tower is a key component of a wind turbine, primarily serving a supporting role and absorbing vibrations. Its importance increases with the capacity and height of the wind turbine. It is typically made of materials such as steel and has a cylindrical structure. Its size and height depend on the installed capacity and design requirements of the wind turbine. Generally speaking, the taller the tower, the higher the wind energy utilization rate. The tower's functions include supporting the nacelle and blades to achieve the optimal windward height, adjusting the height to allow the turbine to operate in the optimal wind energy area, and mitigating vibrations and impacts during operation. The main materials include steel and concrete, each with its own characteristics and applicable scenarios.
[0003] However, the bolts used for tower installation corrode after long-term use, which leads to a significant decrease in the mechanical properties of the bolts. Their core mechanical indicators, such as tensile strength and yield strength, are greatly reduced, making it difficult to meet the long-term stable load-bearing requirements of the tower. In severe cases, it may cause bolt breakage, thereby damaging the overall structural stability of the tower and posing a major safety hazard to the safe operation of the tower. Utility Model Content
[0004] The purpose of this utility model is to solve the problem in the existing technology that the bolts used for tower installation corrode after long-term use, which leads to a significant decrease in the mechanical properties of the bolts. Their core mechanical indicators such as tensile strength and yield strength are greatly reduced, making it difficult to meet the long-term stable load-bearing requirements of the tower. In severe cases, it may cause bolt breakage, thereby destroying the overall structural stability of the tower and posing a major safety hazard to the safe operation of the tower. Therefore, this utility model proposes a tower with multiple anti-corrosion structures.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tower with multiple anti-corrosion structures, comprising a base, a first cylinder, a second cylinder, and a protective device. The first cylinder is disposed on the upper surface of the base, the second cylinder is disposed on the upper surface of the first cylinder, and the protective device is disposed at the bottom of the first cylinder. The first cylinder and the base are fixedly connected by bolts. The protective device includes a retaining sleeve, which is slidably connected to the first cylinder. A stop bar is fixedly connected to the upper surface of the retaining sleeve. A frustum is fixedly connected to one end of the base near the stop bar, and the surface of the frustum is open. The device includes a slot into which the stop bar is inserted. The surface of the stop bar has an arc-shaped groove, and a baffle is rotatably connected to the surface of the truncated cone. By providing a protective device, the clamping sleeve can be stably fitted onto the bolt after installation using the elastic force of a pressure spring. Combined with the locking and fixing of the stop bar and the baffle, the clamping sleeve is not easy to move, thus effectively protecting the bolt and significantly reducing bolt corrosion caused by external environmental factors. This ensures the mechanical properties and service life of the bolt. Furthermore, the clamping sleeve can be lifted simply by rotating the baffle to disengage from the stop bar, making the operation convenient and not affecting subsequent bolt maintenance or replacement.
[0006] Preferably, the baffle has a notch on its surface, and the baffle engages with the arc-shaped groove on the surface of the stop rod. By setting the baffle, when the stop rod is inserted into the frustum, rotating the baffle can engage the baffle with the arc-shaped groove on the surface of the stop rod. This engagement restricts the movement of the stop rod, thereby fixing the sleeve that is compressed by the pressure spring to hold the bolt in place, making it difficult for the sleeve to shift. This provides stable protection for the bolt, reduces bolt corrosion caused by the external environment, and ensures the mechanical properties and service life of the bolt.
[0007] Preferably, a pressure spring is fixedly connected to the upper surface of the ferrule, and the end of the pressure spring away from the ferrule is fixedly connected to the first cylinder. By setting the pressure spring, after the bolt is installed, the pressure spring can generate elastic force and squeeze the ferrule, so that the ferrule is reliably fitted on the outside of the bolt, laying the foundation for subsequent locking and fixing by the stop bar and the baffle, and ensuring that the ferrule is not easy to move when there is no external force intervention.
[0008] Preferably, the upper surface of the first cylinder is provided with a splicing component, which includes a column fixedly connected to the upper surface of the first cylinder. A circular groove is opened at the bottom of the second cylinder, and the column is inserted into the second cylinder. A rotating ring is rotatably connected to the surface of the second cylinder, and a notch is opened at one end of the rotating ring. A locking rod is fixedly connected to the end of the first cylinder near the notch, and the locking rod is adapted to the notch. By setting the splicing component, the second cylinder can be fitted onto the first cylinder during installation. After positioning with the column and initial limiting with the locking rod, the rotating ring is rotated to make the column abut against the semi-circular sleeve. Then, the return spring drives the sliding sleeve to fit onto the column to complete the stable splicing. The installation process is simple and efficient, and the structure is stable after splicing. During subsequent disassembly, only the sliding sleeve needs to be pressed down and the rotating ring needs to be rotated to align the notch with the locking rod to separate the first cylinder and the second cylinder. The disassembly operation is convenient and does not require complicated tools. It can flexibly meet the needs of device assembly and disassembly, and improve the installation efficiency and usage flexibility of the overall device.
[0009] Preferably, one end of the rotating ring is fixedly connected to a support column, and the end of the second cylinder near the support column is fixedly connected to a semi-circular sleeve. The support column and the semi-circular sleeve are engaged. By setting the support column, the rotating ring moves and abuts against the semi-circular sleeve, forming a mechanical limit. In conjunction with the subsequent return spring driving the sliding sleeve to fit the support column, the structural stability of the first cylinder and the second cylinder after splicing is further enhanced, and the splicing part is prevented from loosening or separating during use.
[0010] Preferably, a sliding sleeve is provided on the surface of the semicircular sleeve. The length of the sliding sleeve is less than the length of the semicircular sleeve. By setting the sliding sleeve, it moves upward under the elastic force of the return spring and covers the support column that has abutted against the semicircular sleeve. The physical wrapping forms a double fixation, further locking the position of the support column and preventing the support column from shifting or loosening during use, thereby strengthening the splicing stability of the first cylinder and the second cylinder.
[0011] Preferably, a return spring is fixedly connected to one end of the sliding sleeve, and the end of the return spring away from the sliding sleeve is fixedly connected to the semi-circular sleeve.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, by setting a protective device, after the bolt is installed, the pressure spring will generate elastic force to squeeze the ferrule and fit the bolt. Then, the stop rod is inserted into the truncated cone, and then the baffle is rotated. The baffle and the arc groove on the surface of the stop rod engage, making it difficult for the ferrule to move and protecting the bolt, reducing bolt corrosion. Rotating the baffle to disengage from the stop rod allows the ferrule to be lifted upwards. By setting a protective device, the elastic force of the pressure spring can stably fit the bolt after installation. Combined with the engagement and fixation of the stop rod and the baffle, the ferrule is not easy to move, thus effectively forming a protective enclosure for the bolt, greatly reducing bolt corrosion caused by external environmental factors, ensuring the mechanical properties and service life of the bolt. At the same time, the ferrule can be lifted by simply rotating the baffle to disengage from the stop rod, which is convenient and does not affect the subsequent inspection or replacement of the bolt.
[0014] 2. In this utility model, by setting up a splicing component, during installation, the second cylinder is fitted onto the first cylinder, the column is inserted into the second cylinder, and the locking rod passes through the notch. Then, the rotating ring is rotated, causing the column to move and abut against the semi-circular sleeve. Then, the sliding sleeve is released, and the return spring, freed from its restraint, generates elastic force that pushes the sliding sleeve upward, fitting the column. At this point, the first and second cylinders are spliced. Pressing down on the sliding sleeve allows the rotating ring to rotate, aligning the notch with the locking rod, and pulling upward separates the first and second cylinders. This design achieves the desired splicing effect. The splicing assembly allows the second cylinder to be fitted over the first cylinder during installation. After initial positioning using the column and locking rod, the rotating ring is rotated to make the column abut against the semi-circular sleeve. Then, the return spring drives the sliding sleeve to fit over the column, completing the stable splicing. The installation process is simple and efficient, and the structure is stable after splicing. For subsequent disassembly, simply press down on the sliding sleeve and rotate the rotating ring to align the notch with the locking rod to separate the first and second cylinders. The disassembly operation is convenient and requires no complicated tools. It can flexibly meet the needs of device assembly and disassembly, improving the overall installation efficiency and usage flexibility of the device. Attached Figure Description

[0021] Please see Figures 1-5 This utility model provides a technical solution: a tower with multiple anti-corrosion structures, including a base 1, a first cylinder 2, a second cylinder 3 and a protective device 4. The first cylinder 2 is disposed on the upper surface of the base 1, the second cylinder 3 is disposed on the upper surface of the first cylinder 2, and the protective device 4 is disposed at the bottom of the first cylinder 2. The first cylinder 2 and the base 1 are fixedly connected by bolts.
[0022] In this implementation scheme: the protective device 4 includes a retainer 41, which is slidably connected to the first cylinder 2. A stop bar 43 is fixedly connected to the upper surface of the retainer 41. A frustum 44 is fixedly connected to one end of the base 1 near the stop bar 43. A slot is provided on the surface of the frustum 44. The stop bar 43 is inserted into the slot on the surface of the frustum 44. An arc groove is provided on the surface of the stop bar 43. A baffle 46 is rotatably connected to the surface of the frustum 44. By setting the protective device 4, the retainer 41 can be stably fitted with the bolt by the elastic force of the pressure spring 42 after the bolt is installed. With the locking and fixing of the stop bar 43 and the baffle 46, the retainer 41 is not easy to move, thus effectively forming a protective enclosure for the bolt, greatly reducing bolt corrosion caused by external environmental factors, and ensuring the mechanical properties and service life of the bolt. At the same time, the retainer 41 can be lifted by simply rotating the baffle 46 to disengage from the stop bar 43. The operation is convenient and does not affect the subsequent maintenance or replacement of the bolt.
[0023] Specifically, the surface of the baffle 46 is provided with a notch, and the baffle 46 engages with the arc-shaped groove on the surface of the stop rod 43. By setting the baffle 46, when the stop rod 43 is inserted into the frustum 44, rotating the baffle 46 can engage the baffle 46 with the arc-shaped groove on the surface of the stop rod 43. This engagement restricts the movement of the stop rod 43, thereby fixing the sleeve 41 that is compressed by the pressure spring 42 to hold the bolt in place, making it difficult for the sleeve 41 to shift. This provides stable protection for the bolt, reduces bolt corrosion caused by the external environment, and ensures the mechanical properties and service life of the bolt.
[0024] Specifically, a pressure spring 42 is fixedly connected to the upper surface of the ferrule 41. The end of the pressure spring 42 away from the ferrule 41 is fixedly connected to the first cylinder 2. By setting the pressure spring 42, after the bolt is installed, the pressure spring 42 can generate elastic force and squeeze the ferrule 41, so that the ferrule 41 is reliably fitted on the outside of the bolt. This lays the foundation for the subsequent snap-fit fixing by the stop bar 43 and the baffle 46, and ensures that the ferrule 41 is not easy to move when there is no external force intervention.
[0025] Specifically, the upper surface of the first cylinder 2 is provided with a splicing component 45, which includes a column 458 fixedly connected to the upper surface of the first cylinder 2. A circular groove is formed at the bottom of the second cylinder 3, and the column 458 is inserted into the second cylinder 3. A rotating ring 451 is rotatably connected to the surface of the second cylinder 3, and a notch 453 is formed at one end of the rotating ring 451. A locking rod 452 is fixedly connected to the end of the first cylinder 2 near the notch 453, and the locking rod 452 is adapted to the notch 453. By setting the splicing component 45, the second cylinder 3 can be fitted onto the first cylinder 2 during installation, which facilitates... After positioning with column 458 and initial limiting with clamp 452, rotate rotating ring 451 to make column 454 abut against semi-circular sleeve 456. Then, through return spring 457, slide sleeve 455 is driven to fit column 454 to complete stable splicing. The installation process is simple and efficient, and the structure is stable after splicing. When disassembling, simply press down on slide sleeve 455 and rotate rotating ring 451 to align notch 453 with clamp 452 to separate the first cylinder 2 and the second cylinder 3. The disassembly operation is convenient and does not require complicated tools. It can flexibly meet the needs of device assembly and disassembly, and improve the installation efficiency and usage flexibility of the overall device.
[0026] Specifically, one end of the rotating ring 451 is fixedly connected to a support column 454, and the end of the second cylinder 3 near the support column 454 is fixedly connected to a semi-circular sleeve 456, with the support column 454 and the semi-circular sleeve 456 engaging.
[0027] In this embodiment: by setting up a support column 454, which moves under the drive of the rotating ring 451 and abuts against the semi-circular sleeve 456 to form a mechanical limit, and in conjunction with the subsequent return spring 457 driving the sliding sleeve 455 to fit the support column 454, the structural stability of the first cylinder 2 and the second cylinder 3 after splicing is further enhanced, and the splicing part is prevented from loosening or separating during use.
[0028] Specifically, a sliding sleeve 455 is fitted onto the surface of the semicircular sleeve 456, and the length of the sliding sleeve 455 is less than the length of the semicircular sleeve 456.
[0029] In this embodiment: by setting a sliding sleeve 455, it moves upward under the elastic force of the return spring 457 and fits onto the support column 454 that is already abutting against the semi-circular sleeve 456. The physical wrapping forms a double fixation, further locking the position of the support column 454 and preventing the support column 454 from shifting or loosening during use, thereby strengthening the splicing stability of the first cylinder 2 and the second cylinder 3.
[0030] Specifically, a return spring 457 is fixedly connected to one end of the sliding sleeve 455, and the end of the return spring 457 away from the sliding sleeve 455 is fixedly connected to the semi-circular sleeve 456.
[0031] Working principle: By setting up the protective device 4, after the bolt is installed, the pressure spring 42 will generate elastic force to squeeze the sleeve 41 to fit the bolt. Then, the stop rod 43 is inserted into the frustum 44. Then, the baffle 46 is rotated, and the baffle 46 engages with the arc groove on the surface of the stop rod 43. At this time, the sleeve 41 is difficult to move and protects the bolt, reducing bolt corrosion. Rotating the baffle 46 to disengage from the stop rod 43 allows the sleeve 41 to be lifted upward. By setting up the protective device 4, the elastic force of the pressure spring 42 can stably fit the bolt after the bolt is installed. Combined with the engagement and fixation of the stop rod 43 and the baffle 46, the sleeve 41 is not easy to move, thus effectively forming a protective enclosure for the bolt, greatly reducing bolt corrosion caused by external environmental factors, ensuring the mechanical properties and service life of the bolt. At the same time, afterward, only the baffle 46 needs to be rotated to disengage from the stop rod 43 to lift the sleeve 41. The operation is convenient and does not affect the subsequent inspection or replacement of the bolt.
[0032] By setting the splicing component 45, during installation, the second cylinder 3 is fitted onto the first cylinder 2, the column 458 is inserted into the second cylinder 3, and the locking rod 452 passes through the notch 453. Then, the rotating ring 451 is rotated, which drives the support column 454 to move and abut against the semi-circular sleeve 456. Then, the sliding sleeve 455 is released, and the return spring 457 loses its restraint and generates elastic force to squeeze the sliding sleeve 455 upward and fit the support column 454. At this time, the first cylinder 2 and the second cylinder 3 are spliced. Pressing down on the sliding sleeve 455 will rotate the rotating ring 451 to align the notch 453 with the locking rod 452, and pulling upward will separate the first cylinder 2 and the second cylinder 3. The splicing component 45 allows the second cylinder 3 to be fitted onto the first cylinder 2 during installation. After positioning with the column 458 and initial limiting with the clamping rod 452, the rotating ring 451 is rotated to make the support column 454 abut against the semi-circular sleeve 456. Then, the return spring 457 drives the sliding sleeve 455 to fit onto the support column 454 to complete the stable splicing. The installation process is simple and efficient, and the structure is stable after splicing. During subsequent disassembly, it is only necessary to press down on the sliding sleeve 455 and rotate the rotating ring 451 to align the notch 453 with the clamping rod 452 to separate the first cylinder 2 and the second cylinder 3. The disassembly operation is convenient and does not require complicated tools. It can flexibly meet the needs of device assembly and disassembly, improving the overall installation efficiency and usage flexibility of the device.
