Typically, wind turbine towers are conical or cylindrical in shape, primarily constructed of steel, though composite materials are sometimes used.
[0003] During the installation of wind turbine towers, an embedded fixing method is usually adopted. Although this method can fix the tower, due to the lack of necessary reinforcement structure, the tower may be locally deformed or tilted under high wind loads or extreme weather conditions, reducing the overall stability and safety.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] The cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame, and the cam is fixedly mounted on the support frame.
[0007] Furthermore, the storage assembly includes a fixed shell, which is fixedly connected to the inside of the multiple U-shaped blocks. A slider is slidably connected to the inside of the fixed shell, a pin is fixedly connected to the right side of the outside of the slider, and a moving rod is fixedly connected to the left side of the outside of the slider. A spring is provided on the outside of the moving rod, and the spring is pressed between the fixed shell and the slider.

[0013] Furthermore, a generator is installed on the top of the cylinder, an output end of the generator is fixedly connected to a turntable, and fan blades are installed around the outside of the turntable.
[0014] The utility model has the following beneficial effects:
[0015] 1. In the utility model, when reinforcing a wind turbine tower, the four legs are first moved to make them contact with the ground. Then, the hollow positioning cone is inserted into the soil, and the threaded rod is rotated to move it downward, squeezing the first mounting plate at the bottom, causing it to deform. The movement of the first mounting plate drives the telescopic rod to contract, thereby pushing the external adjustment plate and the second mounting plate to move synchronously.

Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

The clamp 7 is convenient for reinforcing the cylinder 2 to prevent deformation of the cylinder 2, and the outer periphery of the clamp 7 is fixedly connected to a rotating seat 8, and multiple rotating seats 8 are rotatably connected to support legs 9. By setting the support legs 9, it is convenient to support the cylinder 2, and the bottom of multiple support legs 9 are rotatably connected to connecting blocks 10, and multiple connecting blocks 10 are slidably connected to hollow positioning cones 11 inside, and the internal thread of the hollow positioning cone 11 is connected to a threaded rod 12, and the bottom of the hollow positioning cone 11 is fixedly connected to a second mounting plate 15, and the bottom of the threaded rod 12 is rotatably connected to a first mounting plate 13, and the first mounting plate 13 and the second mounting plate 15 are rotatably connected to one end of an adjusting plate 16 around them, and the other ends of multiple adjusting plates 16 are rotatable. The movable connection is provided with a protrusion 17, and a fixing ring 19 is fixedly connected to the outside of the cylinder 2. U-shaped blocks 20 are fixedly connected to the outside of the fixing ring 19 on all sides. Storage components 21 are provided inside the multiple U-shaped blocks 20, and the storage components 21 are used to store the support legs 9. The hollow positioning cone 11 is provided with a first through hole 18 on all sides. Multiple protrusions 17 are slidably connected to the inside of the multiple first through holes 18. A generator 4 is installed on the top of the cylinder 2, and a turntable 5 is fixedly connected to the output end of the generator 4. Fan blades 6 are installed on the outside of the turntable 5 on all sides. The turntable 5 rotates by rotating the fan blades 6, so that the generator 4 generates electricity. At the same time, the upper part of the second mounting plate 15 is fixedly connected to the telescopic rod 14, and the top of the telescopic rod 14 is fixedly connected to the lower part of the first mounting plate 13. The telescopic rod 14 is provided to assist the movement of the first mounting plate 13 and the second mounting plate 15. Mounting holes 3 are provided on all sides of the base 1, and the provision of mounting holes 3 further reinforces the base.
[0027] Specifically, when reinforcing the wind turbine tower, it is first necessary to move the four legs 9 so that they are in full contact with the ground, ensuring that the legs 9 can bear and disperse part of the load of the wind turbine tower. After the legs 9 are in firm contact with the ground, the hollow positioning cone 11 is then inserted into the soil to ensure that it is firmly embedded in the ground to form an effective foundation reinforcement. Then, the threaded rod 12 is rotated to move the threaded rod 12 downward inside the hollow positioning cone 11. In the process of the threaded rod 12 moving downward, the first mounting plate 13 at its bottom will be subjected to the pressure of the threaded rod 12 and gradually deformed. This deformation causes the first mounting plate 13 to be squeezed and move downward, and this action simultaneously drives the telescopic rod 14 connected thereto to contract, and the contraction of the telescopic rod 14 The adjustment plates 16 connected to the outside are driven to move in one step. At the same time, the multiple adjustment plates 16 around the outside of the second mounting plate 15 will also move synchronously. When these adjustment plates 16 move outward at the same time, the four protrusions 17 at the other end will also extend from the inside of the four first through holes 18 under the action of the adjustment plates 16. After the protrusions 17 are extended, they will be directly inserted into the soil, thereby forming a more stable fixed point under the ground. These protrusions 17 can further enhance the stability of the support legs 9, completing the reinforcement of the wind turbine tower, ensuring that the wind turbine tower can remain stable under high wind loads or extreme weather conditions, and avoiding tilting, deformation, etc. of the cylinder 2. This reinforcement method greatly improves the wind resistance and overall stability of the cylinder 2.
[0028] Reference Figure 2 、 Figure 4 and Figure 6 The storage component 21 includes a fixed shell 2101, which is fixedly connected to the interior of a plurality of U-shaped blocks 20. The U-shaped blocks 20 are provided to facilitate the storage of the legs 9. A slider 2102 is slidably connected to the interior of the fixed shell 2101, and a latch 2105 is fixedly connected to the right side of the exterior of the slider 2102. A moving rod 2104 is fixedly connected to the left side of the exterior of the slider 2102. A spring 2103 is sleeved on the exterior of the moving rod 2104, and the spring 2103 is abutted between the fixed shell 2101 and the slider 2102. A slot 23 is provided inside the leg 9, and the latch 2105 is plugged into the slot 23 to improve the stability of the connection. A second through hole 22 is provided on the right side of the interior of the fixed shell 2101, and the latch 2105 is slidably connected to the interior of the second through hole 22. The movement of the latch 2105 is facilitated by providing the second through hole 22.
[0029] Specifically, when the support leg 9 is not needed, first, the operator needs to pull the moving rod 2104. When the moving rod 2104 is pulled, it will drive the external fixed slider 2102 to slide inside the fixed shell 2101. The movement of the slider 2102 will also drive the fixed latch 2105 on the right side to move together. This process will also squeeze the spring 2103 set on the outside of the moving rod 2104, and the spring 2103 will be deformed. When the latch 2105 continues to move to the inside of the fixed shell 2101, the operation of the support leg 9 also needs to be carried out synchronously. The support leg 9 is rotated to the middle position of the U-shaped block 20 to ensure that the support leg 9 It will not interfere with the operation of other structures during storage. After the leg 9 is adjusted into place, the operator needs to loosen the moving rod 2104. At this time, the reaction force of the spring 2103 will cause the pin 2105 to automatically rebound and insert it into the inside of the slot 23. The design of the slot 23 ensures that the pin 2105 can be firmly fixed in the predetermined position after the movement is completed, thereby stably maintaining the storage state of the leg 9. Through this operation step, the leg 9 can be effectively stored in the internal structure of the wind turbine tower. The storage of the leg 9 not only makes the wind turbine tower maintain a more streamlined appearance, but also significantly reduces wind resistance, thereby improving the power generation efficiency of the wind turbine.
[0030] Reference Figure 1 , a wind turbine tower, the cylinder 2 is fixedly connected to the inside of the clamp 7 and the fixing ring 19, and the cylinder 2 is arranged inside the clamp 7 and the fixing ring 19, which plays a role in reinforcing the cylinder 2 and ensuring the stability of the overall structure. A generator 4 is installed on the top of the cylinder 2, and a turntable 5 is fixedly connected to the output end of the generator 4. The generator 4 is responsible for converting wind energy into electrical energy, and a turntable 5 is fixedly connected to its output end. The turntable 5 is used to support and transmit power. Fan blades 6 are installed all around the outside of the turntable 5. A plurality of fan blades 6 are evenly installed around the outside of the turntable 5. These fan blades 6 capture wind energy by interacting with the wind, and drive the turntable 5 to rotate under the push of the wind, thereby driving the rotor of the generator 4 to rotate, thereby generating electrical energy.
[0031] Working principle: When reinforcing a wind turbine tower, first, move the four legs 9 so that the four legs 9 are in contact with the ground. Subsequently, insert the hollow positioning cone 11 into the soil. Then, rotate the threaded rod 12 so that the threaded rod 12 moves downward inside the hollow positioning cone 11. When the threaded rod 12 moves, it squeezes the first mounting plate 13 that is rotatably connected at the bottom, causing the first mounting plate 13 to deform under force. When the first mounting plate 13 moves, it contracts the telescopic rod 14 fixed at the bottom, and moves the adjustment plate 16 that is rotatably connected around the outside and the adjustment plate 16 installed around the outside of the second mounting plate 15 synchronously. When multiple adjustment plates 16 move synchronously, the four protrusions 17 that are rotatably connected at the other end extend from the inside of the four first through holes 18 and are inserted into the inside of the soil. This facilitates the reinforcement of the wind turbine tower and prevents the wind turbine tower from being damaged by high wind loads or extreme weather. Under these conditions, the tower will tilt, which improves the stability of the wind turbine tower. When the support leg 9 is not needed, first, pull the moving rod 2104, and the moving rod 2104 moves with the external fixed slider 2102 to move inside the fixed shell 2101. When the slider 2102 moves, it moves with the external right fixed pin 2105, and at the same time squeezes the spring 2103 on the outside of the moving rod 2104, so that the spring 2103 is deformed under the force. Then, when the pin 2105 moves to the inside of the fixed shell 2101, the support leg 9 is rotated to the middle of the U-shaped block 20, and then, the moving rod 2104 is released, and the pin 2105 is inserted into the inside of the slot 23 under the reaction force of the spring 2103, so that the reinforcement structure is easy to store, the wind turbine tower can maintain a more streamlined shape, reduce wind resistance, and improve the power generation efficiency of the wind turbine.
