[0011] The inner wall of the inner cone sleeve is provided with a plurality of triangular ribs distributed in a circular array, the inner walls of the plurality of triangular ribs are jointly provided with a support tube, and the support tube is sleeved on the outer surface of the wind power tower.

[0012] Among them, the top support assembly includes several support frames, and several support frames are rotatably installed inside the first rotating block. Several support frames are provided with steel cable rings on their inner walls, and several steel cable rings are commonly provided with steel wires inside. Several support frames are provided with first bolts inside, and the support frames are fixedly installed on the bottom of the cabin by the first bolts. The support frames are in the shape of a tripod to provide stable supporting force for the rotating cabin.

[0013] Among them, the installation assembly includes two half-shells, and a plurality of second bolts are commonly arranged inside the two half-shells. A plurality of ribs are arranged on the outer surfaces of the two half-shells, and a second rotating block is arranged on one side of the plurality of ribs. Support rods are rotatably installed inside the plurality of second rotating blocks, and one end of the plurality of support rods is located inside the bottom connecting block. The two half-shells are commonly fixedly installed on the outer surface of the wind turbine tower.

[0017] The steel rope is spirally wound around the outer surface of the wind turbine tower.

[0018] A construction method for a wind power tower reinforcement device, the specific construction method is as follows:

[0019] S1. When encountering strong winds or bad weather, first sleeve the shaft support assembly on the upper part of the outer surface of the wind turbine tower, then rotate and adjust the angle of the top support assembly to fix the top support assembly on the bottom of the cabin to support the stable operation of the cabin in bad weather conditions, and then fix the shaft support assembly to the outer surface of the wind turbine tower. In order to ensure that the installed shaft support assembly has sufficient supporting force, fix the installation assembly on the outer surface of the wind turbine tower, support the installation position of the shaft support assembly through the installation assembly, and provide stable supporting force for the shaft support assembly to prevent the position and angle deviation of the shaft support assembly in the process of supporting the cabin through the top support assembly, resulting in unstable center of gravity of the cabin;

[0020] S2. After the mounting assembly is fixed on the surface of the wind turbine tower, the thrust caused by the rotation of the fan blades and the torque caused by the operation of the nacelle are applied to the top of the wind turbine tower. Therefore, the load-bearing assembly is installed at the lower part of the mounting position of the mounting assembly to further improve the supporting force of the wind turbine tower by increasing the supporting area and the structural design of the tripod;

[0021] S3. After the load-bearing components are installed, the force dissipation mechanism is installed at the bottom of the load-bearing components. The force dissipation mechanism is designed to be spirally coiled around the outer surface of the wind turbine tower. The support structure of the wind turbine tower is strengthened by the force dissipation mechanism. When the wind turbine tower is operating in severe weather, the unbalanced force on the wind turbine tower can be prevented from bending and breaking. The force dissipation mechanism is spirally coiled around the surface of the wind turbine tower to increase the force-bearing area of ​​the wind turbine tower. The structural design of the force dissipation mechanism adds triangular force-bearing ribs on the surface of the wind turbine tower to gradually disperse the force borne by the wind turbine tower, thereby further strengthening the wind turbine tower.

[0022] In summary, the technical effects and advantages of the present invention are as follows:

[0023] 1. The spiral shape design of the force dissipation mechanism in the present invention enables it to be evenly distributed on the outer surface of the wind turbine tower, effectively preventing the wind turbine tower from bending or breaking due to unbalanced force in severe weather, so that the various forces and torques generated by the wind can be better dispersed and balanced; the triangular force-bearing ribs on the force dissipation mechanism not only enhance the stability of the structure, but also gradually disperse and weaken the impact of wind on the wind turbine tower through its unique shape. The ribs are like small supporting points, which disperse the impact force generated by the wind to a larger area and reduce the concentration of local stress. Under strong wind or severe weather conditions, the wind turbine tower needs to withstand huge wind pressure, and the combination of the force dissipation mechanism and the wind turbine tower forms a more solid overall structure.

[0024] 2. The tripod structure design of the load-bearing component in the present invention can more effectively disperse the pressure on the top of the wind turbine tower from the thrust of the fan blade rotation and the torque of the cabin operation. The tripod structure can significantly improve the overall stability of the wind turbine tower due to its high stability and strong bearing capacity. The support of the load-bearing component prevents the top of the wind turbine tower from being subjected to huge forces and torques for a long time, which leads to material fatigue and damage. The load-bearing component disperses the force to a wider area by increasing the support area and adopting a tripod structure. Under severe weather conditions such as strong winds, the wind turbine tower needs to withstand greater wind pressure and wind impact. The load-bearing component enhances the support force of the wind turbine tower, making it more resistant to strong winds and maintaining the stable operation of the wind power equipment. The design of the tripod structure makes the load distribution more uniform, avoiding structural damage caused by excessive local loads. At the same time, the load-bearing component can adjust the position and angle according to actual needs to achieve the best load distribution effect.

[0025] 3. The present invention forms an additional support structure by installing an axis support assembly on the upper outer surface of the wind turbine tower and fixing a top support assembly on the bottom of the cabin. This structure can effectively reduce the shaking and tilting of the cabin under severe weather conditions and ensure stable operation of the cabin. In particular, strong winds often cause huge impacts on wind power equipment. The axis rotation mechanism can effectively disperse and reduce the direct impact of these impacts on the wind turbine tower and the cabin, thereby extending the service life of the equipment. The axis rotation mechanism design enables the reinforcement device to be flexibly adjusted according to actual needs and weather conditions to achieve the best support effect.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1, Reference Figures 1 to 12 A wind turbine tower reinforcement device shown includes an axis rotation mechanism 1 for assisting in supporting the rotation of a nacelle, a support mechanism 2 for reinforcing the top of the wind turbine tower is disposed at the bottom of the axis rotation mechanism 1, and a force dissipation mechanism 3 for improving the support strength of the wind turbine tower is disposed at the bottom of the support mechanism 2;

[0042] The shaft rotation mechanism 1 includes a top support assembly 11 and a shaft support assembly 12. The top support assembly 11 is fixedly installed at the bottom of the nacelle, and the shaft support assembly 12 is installed at the top of the wind power tower to cooperate with the top support assembly 11 to support the stable rotation of the nacelle, and the top support assembly 11 is installed inside the shaft support assembly 12;

[0043] The supporting mechanism 2 comprises a mounting assembly 21 fixedly mounted on the upper part of the wind turbine tower and used to provide supporting force for the shaft support assembly 12 , and a load-bearing assembly 22 for reinforcing the wind turbine tower and providing load-bearing capacity is arranged inside the mounting assembly 21 .

[0044] It is worth noting that when encountering strong winds or bad weather, the shaft support assembly 12 is first sleeved on the upper part of the outer surface of the wind turbine tower, and then the angle of the top support assembly 11 is rotated to adjust the top support assembly 11 to fix the top support assembly 11 on the bottom of the cabin to support the cabin to operate stably under bad weather conditions, and then the shaft support assembly 12 is fixed and fastened to the outer surface of the wind turbine tower. In order to ensure that the installed shaft support assembly 12 has sufficient supporting force, the installation assembly 21 is fixed to the outer surface of the wind turbine tower, and the installation position of the shaft support assembly 12 is supported by the installation assembly 21, and a stable supporting force is provided for the shaft support assembly 12 to prevent the shaft support assembly 12 from being offset in position and angle during the process of supporting the cabin through the top support assembly 11, resulting in an unstable center of gravity of the cabin;

[0045] Among them, by installing an axis support assembly 12 on the upper outer surface of the wind turbine tower and fixing the top support assembly 11 on the bottom of the cabin, an additional support structure is formed, which can effectively reduce the shaking and tilting of the cabin under severe weather conditions and ensure the stable operation of the cabin. In particular, strong winds often cause huge impacts on wind power equipment. The axis rotation mechanism 1 can effectively disperse and reduce the direct impact of these impacts on the wind turbine tower and the cabin, and extend the service life of the equipment. The design of the axis rotation mechanism 1 enables the reinforcement device to be flexibly adjusted according to actual needs and weather conditions to achieve the best support effect.

[0046] By fixing the mounting assembly 21 on the outer surface of the wind turbine tower, an additional support point is provided for the shaft support assembly 12, ensuring that the shaft support assembly 12 will not be displaced in position and angle when subjected to great pressure, thereby maintaining the center of gravity of the cabin stable.

[0047] After the mounting assembly 21 is fixed on the surface of the wind turbine tower, the thrust caused by the rotation of the fan blades and the torque caused by the operation of the nacelle are applied to the top of the wind turbine tower, so the load-bearing assembly 22 is installed below the mounting position of the mounting assembly 21 to further improve the supporting force of the wind turbine tower by increasing the supporting area and the structural design of the tripod;

[0048] Among them, the tripod structure design of the load-bearing component 22 can more effectively disperse the pressure on the top of the wind turbine tower from the thrust of the fan blade rotation and the torque of the nacelle operation. The tripod structure can significantly improve the overall stability of the wind turbine tower due to its high stability and strong load-bearing capacity.

[0049] The support of the load-bearing component 22 prevents stress concentration at the top of the wind turbine tower due to long-term exposure to huge forces and torques, which may lead to material fatigue and damage. The load-bearing component 22 disperses the force to a wider area by increasing the supporting area and adopting a tripod structure, thereby reducing stress concentration and extending the service life of the wind turbine tower.

[0050] Under severe weather conditions such as strong winds, the wind turbine tower needs to withstand greater wind pressure and wind impact. The load-bearing component 22 enhances the supporting force of the wind turbine tower, making it more resistant to strong winds and maintaining the stable operation of the wind turbine equipment. The design of the tripod structure makes the load distribution more uniform, avoiding structural damage caused by excessive local loads. At the same time, the load-bearing component 22 can adjust its position and angle according to actual needs to achieve the best load distribution effect.

[0051] After the load-bearing component 22 is installed, the force dissipation mechanism 3 is installed at the lower part of the load-bearing component 22. The force dissipation mechanism 3 is designed to be spirally wound around the outer surface of the wind turbine tower. The support structure of the wind turbine tower is strengthened by the force dissipation mechanism 3. When the wind turbine tower is operating in severe weather, the unbalanced force on the wind turbine tower can be prevented from bending and breaking. The force dissipation mechanism 3 is spirally wound around the surface of the wind turbine tower to increase the force-bearing area of ​​the wind turbine tower. The structural design of the force dissipation mechanism 3 adds triangular force-bearing ribs to the surface of the wind turbine tower to gradually disperse the force borne by the wind turbine tower, thereby further strengthening the wind turbine tower.

[0052] The spiral shape of the force dissipation mechanism 3 enables it to be evenly distributed on the outer surface of the wind turbine tower, effectively preventing the wind turbine tower from bending or breaking due to unbalanced force in bad weather, so that various forces and torques generated by wind can be better dispersed and balanced;

[0053] The force dissipation mechanism 3 is not only coiled on the surface of the wind turbine tower, but also increases the force-bearing area of ​​the wind turbine tower through its structural design. Under the same wind force, the force borne by each unit area is reduced, thereby improving the overall support force and bearing capacity of the wind turbine tower;

[0054] The triangular shaped load-bearing ribs on the force dissipation mechanism 3 not only enhance the stability of the structure, but also gradually disperse and weaken the impact of wind on the wind turbine tower through its unique shape. The ribs are like small supporting points, which disperse the impact force generated by the wind to a larger area and reduce the concentration of local stress. In strong winds or severe weather conditions, the wind turbine tower needs to withstand huge wind pressure. The design of the force dissipation mechanism 3 enables the wind turbine tower to better withstand these wind pressures and maintain its structural integrity and stability, thereby extending the service life of the wind power equipment.

[0055] The combination of the force dissipation mechanism 3 and the wind turbine tower forms a more solid overall structure. When subjected to external forces, the shape and stability can be better maintained. The design of the force dissipation mechanism 3 takes into account the optimization of stress distribution. Through the combination of its spiral shape and triangular ribs, the stress distribution of the wind turbine tower is more uniform when subjected to wind force, reducing the risk of structural damage caused by stress concentration.

[0056] Embodiment 2: Based on the shaft rotation mechanism 1 proposed in Embodiment 1, this embodiment provides a further technical solution for the shaft support assembly 12 and the top support assembly 11.

[0057] The shaft support assembly 12 includes a half-missing ring 124, which is sleeved on the upper part of the outer surface of the wind power tower, and the outer surface of the half-missing ring 124 is provided with a tying ring 123 for fixing the position of the half-missing ring 124, and the bottom of the half-missing ring 124 is provided with an inner cone sleeve 128, and the upper part of the outer surface of the inner cone sleeve 128 is provided with a sealing ring 125, and the lower part of the outer surface of the inner cone sleeve 128 is provided with a fixed sleeve 126, and the fixed sleeve 126 and the sealing ring 125 are jointly provided with a plurality of shaft rods 127 distributed in an annular array inside, and the outer surfaces of the fixed sleeve 126 and the sealing ring 125 are jointly sleeved with a cone cover 121;

[0058] The outer surface of the cone cover 121 is provided with a plurality of first rotating blocks 122 distributed in a ring array, and the bottom of the inner cone sleeve 128 is provided with a plurality of bottom connecting blocks 129 distributed in a ring array.

[0059] The inner wall of the inner cone sleeve 128 is provided with a plurality of triangular ribs 120 distributed in a ring array, and the inner walls of the plurality of triangular ribs 120 are commonly provided with a support tube 1211, and the support tube 1211 is sleeved on the outer surface of the wind power tower.

[0060] It is worth noting that when in use, the half-missing ring 124 and the support tube 1211 are mounted on the surface of the wind turbine tower, and then the position of the half-missing ring 124 is fixed by the tie ring 123. Then the user rotates the support frame 112 inside the first rotating block 122, and then installs the support frame 112 on the bottom of the cabin through the first bolt 111. After the support frame 112 is installed, the steel wire 114 is passed through the steel cable ring 113, and then the steel wire 114 is fixed.

[0061] The top support assembly 11 includes a plurality of support frames 112, and the plurality of support frames 112 are rotatably installed inside the first rotating block 122. The inner walls of the plurality of support frames 112 are provided with steel cable rings 113, and the interiors of the plurality of steel cable rings 113 are commonly provided with steel wires 114. The interiors of the plurality of support frames 112 are provided with first bolts 111, and the support frames 112 are fixedly installed on the bottom of the cabin by the first bolts 111. The support frames 112 are in the shape of a tripod and are used to provide stable support force for the rotating cabin.

[0062] Among them, when encountering strong winds, the wind direction changes the direction of the wind blades, and the angle adjustment of the wind blades will also drive the cabin to rotate. When the cabin rotates, it drives the support frame 112 to rotate, and the support frame 112 drives the cone cover 121 to rotate through the first rotating block 122. The set shaft rod 127 can assist the rotation of the cone cover 121, and the set cone cover 121 is conical. The force exerted on the cabin by the support frame 112 will be transmitted to the cone cover 121 through the first rotating block 122, and the cone cover 121 applies force to the inner cone sleeve 128 through the shaft rod 127. The triangular ribs 120 arranged on the inner wall of the inner cone sleeve 128 can support the force transmitted by the cone cover 121, which can ensure that the surface of the wind turbine tower is evenly stressed during the rotation of the cabin, reduce the shaking and tilting of the cabin, and ensure the stable operation of the cabin.

[0063] Embodiment 3: Based on the support mechanism 2 proposed in Embodiment 1, this embodiment provides a further technical solution for the installation component 21 and the load-bearing component 22.

[0064] The mounting assembly 21 includes two half-shells 212, and a plurality of second bolts 214 are commonly arranged inside the two half-shells 212. A plurality of ribs 213 are arranged on the outer surfaces of the two half-shells 212, and a second rotating block 215 is arranged on one side of the plurality of ribs 213. Support rods 211 are rotatably installed inside the plurality of second rotating blocks 215, and one end of the plurality of support rods 211 is located inside the bottom connecting block 129. The two half-shells 212 are commonly fixedly installed on the outer surface of the wind turbine tower.

[0065] It is worth noting that after the shaft support assembly 12 is installed, the user installs the two half-shells 212 on the surface of the wind turbine tower, and then fixes them with the second bolts 214, and finally rotates the support rod 211 inside the second rotating block 215 to install it inside the bottom connecting block 129. The structural cooperation between the ribs 213 and the support rod 211 can support the installation position of the inner cone sleeve 128, and the force exerted on the inner cone sleeve 128 is shared by the support rod 211.

[0066] The load-bearing assembly 22 includes a plurality of support rods 221, and the plurality of support rods 221 are rotatably mounted inside the second rotating block 215. A support plate 222 is rotatably mounted on one end of the plurality of support rods 221. A slot 224 is provided on the outer surface of the plurality of support plates 222. A locking ring 223 is commonly provided inside the plurality of slots 224. A ring groove 225 is provided on the bottom of the plurality of support plates 222.

[0067] Among them, after installing the half-shell 212, rotate the support rod 221 inside the second rotating block 215, and then place the support plate 222 tightly against the surface of the wind turbine tower, and finally place the locking ring 223 inside the slot 224, and then fix the installation position of the support plate 222 through the locking ring 223. The installed support rod 221 and the rib plate 213 form a triangular support structure, and the half-shell 212 is located at the upper part of the wind turbine tower near the cabin, so when encountering severe weather conditions such as strong winds, the wind turbine tower needs to withstand greater wind pressure and wind impact.

[0068] Embodiment 3: Based on the force dissipating mechanism 3 proposed in Embodiment 1, this embodiment provides a further technical solution of the force dissipating mechanism 3.

[0069] The force dissipation mechanism 3 includes a first steel cable ring 31 and a second steel cable ring 35. The first steel cable ring 31 is located inside the ring groove 225 and is used to fix the support plate 222 close to the outer surface of the wind turbine tower. The second steel cable ring 35 is fixedly installed on the outer surface of the wind turbine tower. The outer surface of the first steel cable ring 31 is provided with a plurality of steel wire locks 32, and the outer surface of the second steel cable ring 35 is provided with a plurality of bolt blocks 36. Steel ropes 34 are arranged between the plurality of bolt blocks 36 and the steel wire locks 32, and the outer surfaces of the plurality of steel ropes 34 are sleeved with a plurality of force blocks 33 distributed at equal intervals.

[0070] It is worth noting that after the support plate 222 is installed, the first steel cable ring 31 is installed inside the ring groove 225, and then the position of the support plate 222 is further fixed by the first steel cable ring 31. Then the user spirally winds the steel rope 34 and the force block 33 and distributes them on the outer surface of the wind tower. The several force blocks 33 are all triangular in shape, and the inner wall of the force block 33 is provided with an arc groove that is close to the outer surface of the wind tower. The steel rope 34 is spirally wound on the outer surface of the wind tower.

[0071] By combining the spirally wound steel rope 34 and the triangular rib stress block 33, the stress distribution of the wind turbine tower is more uniform when subjected to wind force, thereby reducing the risk of structural damage caused by stress concentration.

[0072] The present invention provides a construction method for a wind power tower reinforcement device, and the specific construction method is as follows:

[0073] S1. When encountering strong winds or bad weather, first sleeve the shaft support assembly 12 on the upper part of the outer surface of the wind turbine tower, then rotate and adjust the angle of the top support assembly 11 to fix the top support assembly 11 on the bottom of the cabin to support the cabin to operate stably under bad weather conditions, and then fix the shaft support assembly 12 to the outer surface of the wind turbine tower. In order to ensure that the installed shaft support assembly 12 has sufficient supporting force, fix the installation assembly 21 on the outer surface of the wind turbine tower, support the installation position of the shaft support assembly 12 through the installation assembly 21, and provide a stable supporting force for the shaft support assembly 12 to prevent the shaft support assembly 12 from being offset in position and angle during the process of supporting the cabin through the top support assembly 11, resulting in an unstable center of gravity of the cabin;

[0074] S2. After the mounting assembly 21 is fixed on the surface of the wind turbine tower, the thrust caused by the rotation of the fan blades and the torque caused by the operation of the nacelle are applied to the top of the wind turbine tower. Therefore, the load-bearing assembly 22 is installed below the mounting position of the mounting assembly 21 to further improve the supporting force of the wind turbine tower by increasing the supporting area and the structural design of the tripod;

[0075] S3. After the load-bearing component 22 is installed, the force dissipation mechanism 3 is installed at the lower part of the load-bearing component 22. The force dissipation mechanism 3 is designed to be spirally wound around the outer surface of the wind turbine tower. The support structure of the wind turbine tower is strengthened by the force dissipation mechanism 3. When the wind turbine tower is operating in severe weather, the unbalanced force on the wind turbine tower is prevented from bending and breaking. The force dissipation mechanism 3 is spirally wound around the surface of the wind turbine tower to increase the force-bearing area of ​​the wind turbine tower. The structural design of the force dissipation mechanism 3 adds triangular force-bearing ribs to the surface of the wind turbine tower to gradually disperse the force borne by the wind turbine tower, thereby further strengthening the wind turbine tower.
