Description

Technical Field

[0001] This invention belongs to the technical field of wind turbine tower transition section, specifically a wind turbine tower transition section structure. Background Technology

[0002] A wind turbine tower is the supporting structure of a wind turbine generator set. It is generally a column or cone structure made of rolled or welded steel plates, with internal mechanical and electrical components and other auxiliary equipment. The wind turbine tower includes the tower body, ladders, cables, cable ladders, platforms and other structures.

[0003] In existing technologies, wind turbine towers consist of two parts, upper and lower, connected by a transition section. In existing technologies, the transition section is usually fixed to the upper and lower parts of the wind turbine tower using bolt-type components or flanges. This connection method requires loosening the bolts during installation and disassembly. However, bolts rust during daily use, and once corroded, they are not easy to loosen. Furthermore, for wind turbine towers, stress concentration during use means that fatigue risk is likely to occur. Stress concentration will reduce the service life of the wind turbine tower and may even lead to the risk of the wind turbine tower collapsing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is: a wind turbine tower conversion section structure, comprising: an inner tower cylinder, wherein support mechanisms are uniformly arranged on the outside of the inner tower cylinder;

[0005] An adjustment mechanism is installed at the bottom of the inner tower, and the bottom of the support mechanism is connected to the top of the adjustment mechanism; The adjustment mechanism includes: The outer tower tube has its inner wall connected to the bottom of the inner tower tube. The outer wall of the outer tower tube is evenly provided with adjustment holes, which allow the inner tower tube to move up and down. The overall height of the transition section can be finely adjusted by moving the inner tube up and down to compensate for the height deviation in tower manufacturing and foundation construction. The protective components are evenly distributed on the outer wall of the outer tower, and the top of the protective components is in contact with the inner wall of the outer tower. The protective components protect the bolts that fix the inner tower, preventing the bolts from contacting the outside environment and rusting, which would cause them to loosen.

[0006] Furthermore, the adjustment mechanism also includes: Adjustable cylinders are evenly arranged on the inner wall of the outer tower cylinder. The inner wall of the adjustable cylinder is connected to the outer wall of the inner tower cylinder. The number and spacing of the adjustable cylinders can be adapted to inner tower cylinders of different diameters. During on-site installation, the outer cylinder can be fixed to the upper nacelle interface first, and then the lower tower interface can be aligned by moving the inner cylinder up and down. Precise alignment of the upper and lower interfaces is not required, which improves the installation error tolerance. Bolts are installed on the inner wall of the adjustment holes. The bolts are used to connect the adjustment cylinder to the outer tower cylinder and to adjust the height of the adjustment cylinder by adjusting it in different adjustment holes.

[0007] Furthermore, the adjustment mechanism also includes: A connecting block, the outer wall of which is fixedly connected to the inner wall of the outer tower, and the top of which is connected to the end of the protective component. The connecting block hangs the protective component on the top of the outer tower, so that the protective component is fixed by external force. The buckle plate has a fixing screw on its top, which secures the buckle plate to the top of the outer tower.

[0008] Furthermore, the support mechanism includes: The connecting platform is evenly distributed on the outer wall of the outer tower, and both the connecting platform and the outer tower are made of reinforced concrete. The support legs are evenly arranged on the outer wall of the inner tower. The top of the support legs is installed on the outer wall of the inner tower, and the bottom of the support legs is connected to the top of the connecting platform. The support legs are connected by flanges to connect the inner tower and the outer tower. The sleeve is installed on the top of the outrigger and is fitted over the outside of the outrigger. The sleeve is made of waterproof and flexible material and is adjusted according to the length of the outrigger during use so that the entire outrigger is wrapped by the sleeve.

[0009] Furthermore, the support mechanism also includes: A semi-circular sleeve is evenly distributed on the outer wall of the sleeve, and the material of the semi-circular sleeve is the same as that of the sleeve. A connecting rope is disposed inside the semi-circular sleeve.

[0010] Furthermore, the protective component includes: A protective sleeve is installed at the end of the bolt away from the inner tower cylinder. The inner wall of the protective sleeve is fitted with the outer wall of the bolt. An exhaust chamber is provided on the inner wall of the protective sleeve near the bolt. The material around the exhaust chamber is rubber, which can squeeze out the air in the chamber and keep it sealed through flexible changes. A connecting hole is provided on the side of the exhaust chamber near the bolt, which connects the exhaust chamber with the space of the bolt. The side of the protective sleeve where the roller and hanging rope are installed is grooved and is a rigid shell.

[0011] Furthermore, the protective component also includes: A hanging rope is installed inside the buckle plate, and one end of the hanging rope is connected to a connecting block; A limiting rod is installed on the top of the inner wall of the protective sleeve. The two ends of the limiting rod are rotatably connected to the inner wall of the protective sleeve. The limiting rod changes the path of the hanging rope into the protective sleeve, so that the hanging rope can be pulled out and retracted more smoothly, reducing the volume of the protective sleeve and thus reducing the space occupied by the protective sleeve.

[0012] Furthermore, the protective component also includes: A reel, which is installed at the bottom of the inner wall of the protective sleeve, with one end of the reel rotatably connected to the inner wall of the protective sleeve; An air intake pipe is installed on the inner wall of the exhaust chamber. The top of the air intake pipe extends to the outside of the protective sleeve. The air intake pipe allows the air in the space between the exhaust chamber and the insertion bolt to be discharged. Then, the air intake pipe is blocked to keep the bolt isolated from the outside.

[0013] Furthermore, the protective component also includes: A handle is installed at the other end of the reel. The handle drives the reel to rotate, allowing manual unwinding or winding of the connecting rope. The clamping block has its top slidably connected to the bottom of the protective sleeve, and its interior engages with the bottom of the handle.

[0014] The beneficial effects of this invention are as follows: 1. This invention, by setting an adjustment mechanism, fixes the adjustment cylinder to the inner wall of the outer tower as needed, allowing the top of the inner tower to be installed with the wind turbine tower, and the outer tower and support mechanism to be installed with the wind turbine tower, thus fixing the conversion section as a whole. It adapts to the interface height differences of different nacelles or towers, and inner towers of different diameters. Different length bolts are selected to support the fixing of the adjustment cylinder, compensating for the distance between the adjustment cylinder and the outer tower after connecting inner towers of different diameters. During use, there is no need to replace the entire conversion section; only the position of the inner tower and the replacement of inner towers of different diameters are needed to make it compatible with multiple specifications of units, reducing the cost of universal design. The separate design of inner and outer cylinders can reduce the size and weight of individual components, facilitating transportation.

[0015] 2. This invention uses a support mechanism where the sleeve is rolled up and positioned above the support leg. After the support leg is connected to the inner and outer tower cylinders, the sleeve is unfolded downwards to enclose the support leg. Then, the connecting ropes on the semi-circular sleeve are tied one by one to reduce the internal space of the sleeve and seal the upper and lower openings of the flange, thus isolating the flange from contact with the outside world, reducing loosening caused by rusting of the flange, and protecting the support leg.

[0016] 3. This invention, by setting up a protective component, inserts a protective sleeve into one end of the bolt protruding from the outer tower cylinder. Then, the air is extracted from the protective sleeve by external force through the suction pipe, so that the bolt is wrapped. Then, the top of the suction pipe is blocked, and the clamping block is pushed out from the bottom of the protective sleeve, so that the clamping block locks the handle, preventing the handle from rotating and keeping the hanging rope at a fixed length. This ensures a tight connection between the protective sleeve and the outer tower cylinder, reducing the risk of the protective sleeve gradually loosening and falling off due to vibration, thus exposing the bolt to the external environment.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Example 1, please refer to Figures 1-5The present invention provides a technical solution: a wind turbine tower conversion section structure is described below.

[0021] Includes: inner tower 2, with support mechanisms 3 evenly distributed on the outside of the inner tower 2; Adjustment mechanism 1 is installed at the bottom of the inner tower 2, and the bottom of the support mechanism 3 is connected to the top of the adjustment mechanism 1; During installation, select an inner tower 2 of the corresponding diameter for installation, fix the inner tower 2 to the inner wall of the adjusting mechanism 1, and adjust the height of the inner tower 2. After determining the height, install the inner tower 2 and the adjusting mechanism 1 as a transition section to connect with the wind turbine tower. The support mechanism 3 supports the adjusting mechanism 1 and the inner tower 2.

[0022] Adjustment mechanism 1 includes: The outer tower 101 has its inner wall connected to the bottom of the inner tower 2. The outer wall of the outer tower 101 is evenly provided with adjustment holes 102. The adjustment holes 102 can move the inner tower 2 up and down. The overall height of the conversion section can be finely adjusted by moving the inner tower up and down to make up for the height deviation in tower manufacturing and foundation construction. The protective components 103 are evenly distributed on the outer wall of the outer tower 101. The top of the protective components 103 is in contact with the inner wall of the outer tower 101. The protective components 103 protect the bolts 105 that fix the inner tower 2, preventing the bolts 105 from contacting the outside environment and rusting, thus preventing them from loosening.

[0023] The regulating mechanism 1 also includes: Adjusting cylinders 104 are evenly arranged on the inner wall of the outer tower 101. The inner wall of the adjusting cylinders 104 is connected to the outer wall of the inner tower 2. The number and spacing of the adjusting cylinders 104 can be adapted to inner towers 2 of different diameters. During on-site installation, the outer cylinder and the upper nacelle interface can be fixed first, and then the lower tower interface can be aligned by moving the inner cylinder up and down. There is no need to precisely align the upper and lower interfaces, which improves the installation error tolerance. Bolt 105 is installed on the inner wall of adjustment hole 102. Bolt 105 is used to connect adjustment cylinder 104 to outer tower cylinder 101 and to adjust the height of adjustment cylinder 104 by adjusting it in different adjustment holes 102.

[0024] The regulating mechanism 1 also includes: The connecting block 108 has its outer wall fixedly connected to the inner wall of the outer tower 101, and its top is connected to the end of the protective component 103. The connecting block 108 hangs the protective component 103 on the top of the outer tower 101, so that the protective component 103 is fixed by external force. The buckle plate 106 has a fixing screw 107 on its top. The fixing screw 107 fixes the buckle plate 106 to the top of the outer tower 101 and connects the top of the protective assembly 103 to the top of the outer tower 101.

[0025] In use, the adjusting cylinder 104 is fixed to the outer wall of the inner tower cylinder 2 according to its diameter. Then, the adjusting cylinder 104 is inserted into the adjusting hole 102 of the outer tower cylinder 101 with bolts 105. According to the required height, the adjusting cylinder 104 is fixed to the inner wall of the outer tower cylinder 101, so that the top of the inner tower cylinder 2 is installed with the wind turbine tower. The outer tower cylinder 101 and the support mechanism 3 are installed with the wind turbine tower, so that the conversion section is fixed as a whole. It can adapt to the interface height difference of different nacelles or towers and inner tower cylinders 2 with different diameters. Bolts 105 of different lengths are selected to support the fixing of the adjusting cylinder 104, which compensates for the distance between the adjusting cylinder 104 and the outer tower cylinder 101 after the inner tower cylinders 2 with different diameters are connected. In use, there is no need to replace the entire conversion section. By simply adjusting the position of the inner tower cylinder 2 and replacing the inner tower cylinder 2 with one of different diameters, it can be compatible with multiple specifications of units, reducing the cost of universal design. The separate design of inner and outer cylinders can reduce the size and weight of individual components, making transportation easier.

[0026] Supporting mechanism 3 includes: Connecting platforms 305 are evenly distributed on the outer wall of the outer tower 101, and both the connecting platforms 305 and the outer tower 101 are made of reinforced concrete. Support legs 301 are evenly arranged on the outer wall of the inner tower 2. The top of the support legs 301 is installed on the outer wall of the inner tower 2, and the bottom of the support legs 301 is connected to the top of the connecting platform 305. The support legs 301 are connected by flanges to connect the inner tower 2 and the outer tower 101. Sleeve 302 is installed on the top of outrigger 301 and is fitted over the outside of outrigger 301. Sleeve 302 is made of waterproof and flexible material. During use, it is adjusted according to the length of outrigger 301 so that the entire outrigger 301 is wrapped by sleeve 302.

[0027] Supporting mechanism 3 also includes: Semicircular sleeve 303 is evenly distributed on the outer wall of sleeve 302, and the material of semicircular sleeve 303 is the same as that of sleeve 302. Connecting rope 304 is located inside the semi-circular sleeve 303.

[0028] Initially, the sleeve 302 is rolled up and positioned above the support leg 301. After the support leg 301 is connected to the inner tower 2 and the outer tower 101, the sleeve 302 is unfolded downwards so that it wraps around the support leg 301. Then, the connecting ropes 304 on the semi-circular sleeve 303 are tied one by one to reduce the internal space of the sleeve 302, seal the upper and lower openings of the flange, isolate the flange from contact with the outside world, reduce loosening caused by rusting of the flange, and protect the support leg 301.

[0029] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the protective component 103 includes: The protective sleeve 1031 is installed at the end of the bolt 105 away from the inner tower cylinder 2. The inner wall of the protective sleeve 1031 is fitted with the outer wall of the bolt 105. An exhaust chamber 1037 is provided on the inner wall of the protective sleeve 1031 near the bolt 105. The material around the exhaust chamber 1037 is rubber, which can squeeze out the air in the chamber and keep it sealed through flexible changes. A connecting hole 1033 is provided on the side of the exhaust chamber 1037 near the bolt 105. The connecting hole 1033 connects the exhaust chamber 1037 with the space of the insertion bolt 105. The side of the protective sleeve 1031 where the roller 1038 and the hanging rope 1034 are installed is grooved into a rigid shell.

[0030] The protective component 103 also includes: The hanging rope 1034 is installed inside the buckle plate 106, and one end of the hanging rope 1034 is connected to the connecting block 108; The limiting rod 1035 is installed on the top of the inner wall of the protective sleeve 1031. The two ends of the limiting rod 1035 are rotatably connected to the inner wall of the protective sleeve 1031. The limiting rod 1035 changes the path of the hanging rope 1034 into the protective sleeve 1031, so that the hanging rope 1034 can be pulled out and retracted more smoothly, reducing the volume of the protective sleeve 1031 and thus reducing the space occupied by the protective sleeve 1031.

[0031] The protective component 103 also includes: A spool 1038 is installed at the bottom of the inner wall of the protective sleeve 1031, and one end of the spool 1038 is rotatably connected to the inner wall of the protective sleeve 1031. The suction pipe 1036 is installed on the inner wall of the exhaust chamber 1037. The top of the suction pipe 1036 extends to the outside of the protective sleeve 1031. The suction pipe 1036 allows the air in the space between the exhaust chamber 1037 and the insertion bolt 105 to be discharged. Then the suction pipe 1036 is blocked to keep the bolt 105 isolated from the outside.

[0032] The protective component 103 also includes: Handle 1039 is installed at the other end of the reel 1038. Handle 1039 drives the reel 1038 to rotate, and the connecting rope 304 can be manually released or wound up. Clamping block 1032, the top of clamping block 1032 is slidably connected to the bottom of protective sleeve 1031, and the inside of clamping block 1032 is engaged with the bottom of handle 1039.

[0033] In use, after securing the bolt 105, insert the protective sleeve 1031 into the end of the bolt 105 that protrudes from the outer tower cylinder 101. Then, use external force to extract the air from the protective sleeve 1031 through the suction pipe 1036, thus encasing the bolt 105. Next, block the top of the suction pipe 1036 and install the protective shell on the outside of the outer tower cylinder 101. Then, pull the hanging rope 1034 out from the protective sleeve 1031 and pull the connecting block 108 connected to the hanging rope 1034 to the inner wall of the outer tower cylinder 101, fitting it against the inner wall of the outer tower cylinder 101. Then, pass the buckle plate 106 through... The screw 107 is fixed to the outer tower 101, securing the hanging rope 1034. At this time, the handle 1039 drives the reel 1038 to rotate, and after the handle 1039 is in a vertical position, the clamp 1032 is pushed out from the bottom of the protective sleeve 1031, so that the clamp 1032 locks the handle 1039, preventing the handle 1039 from rotating, keeping the hanging rope 1034 at a fixed length, ensuring a tight connection between the protective sleeve 1031 and the outer tower 101, reducing the risk of the protective sleeve 1031 gradually loosening and falling off due to vibration, and thus exposing the bolt 105 to the external environment.

[0034] The specific workflow is as follows: In use, according to the diameter of the inner tower 2, the adjusting cylinder 104 is attached to the outer wall of the inner tower 2 for fixation. Then, the adjusting cylinder 104 is inserted into the adjusting hole 102 of the outer tower 101 by bolts 105. According to the required height, the adjusting cylinder 104 is fixed to the inner wall of the outer tower 101, so that the top of the inner tower 2 is installed with the wind turbine tower. The outer tower 101 and the support mechanism 3 are installed with the wind turbine tower, so that the conversion section is fixed as a whole. It can adapt to the interface height difference of different nacelles or towers and inner tower 2 with different diameters. There is no need to replace the entire conversion section during use. Initially, the sleeve 302 is rolled up and positioned above the support leg 301. After the support leg 301 is connected to the inner tower 2 and the outer tower 101, the sleeve 302 is unfolded downwards so that it wraps around the support leg 301. Then, the connecting ropes 304 on the semi-circular sleeve 303 are tied one by one to reduce the internal space of the sleeve 302, seal the upper and lower openings of the flange, isolate the flange from contact with the outside world, reduce loosening caused by rusting of the flange, and protect the support leg 301. After securing bolt 105, insert protective sleeve 1031 into the end of bolt 105 protruding from outer tower 101. Then, use external force to extract air from protective sleeve 1031 through suction pipe 1036, encasing bolt 105. Next, block the top of suction pipe 1036 and install the protective shell on the outside of outer tower 101. Then, pull hanging rope 1034 out from protective sleeve 1031 and pull connecting block 108 connected to hanging rope 1034 to outer tower 101. The inner wall of the outer tower 101 is attached to the inner wall of the outer tower 101. Then, the buckle plate 106 is fixed to the outer tower 101 by the fixing screw 107, so that the hanging rope 1034 is fixed. At this time, the handle 1039 drives the roller 1038 to rotate. After the handle 1039 is in a vertical position, the clamp 1032 is pushed out from the bottom of the protective sleeve 1031, so that the clamp 1032 locks the handle 1039 to prevent the handle 1039 from rotating, so that the hanging rope 1034 keeps its length fixed.

[0035] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
