Description

Technical Field

[0001] This utility model relates to the field of wind turbine generator technology, and in particular to a tower structure for onshore wind turbine generators suitable for complex terrain. Background Technology

[0002] The wind turbine tower is the key structure supporting the entire unit. It stands tall and is generally made of multiple sections of steel. It has sufficient strength and stability to withstand harsh environments such as strong winds, and steadily supports the nacelle and blades to the appropriate height, ensuring the safe and efficient operation of the wind turbine.

[0003] Wind speed increases with altitude, determined by the characteristics of the atmospheric boundary layer. Near the ground, wind speed is relatively low due to ground friction. The tower lifts the wind turbine blades to higher altitudes, allowing them to operate in areas with higher wind speeds. Therefore, wind turbine towers are necessary. However, traditional wind turbine towers are not suitable for complex terrain. Installing traditional support structures on terrains with varying slopes is difficult due to the challenges of accurate positioning and alignment. The undulating terrain makes it hard to ensure that each part of the support structure is installed precisely according to design requirements, leading to deviations in the tower's verticality and affecting the installation and operation of subsequent equipment.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0025] Example 1:

[0026] Reference Figures 1-5This is the first embodiment of the present utility model. This embodiment provides an onshore wind turbine tower structure suitable for complex terrain, including a tower body 1, an installation plate 2 fixedly connected to the outside of the tower body 1, a connecting component 3 provided on the outside of the installation plate 2, an adjustment component 4 provided on one side of the connecting component 3, and a limit component 5 provided on one side of the adjustment component 4.

[0027] The wind turbine tower is a key supporting structure for wind power generation. Its principle is to use its own height to lift the nacelle and blades to a high altitude where the wind is strong, reducing interference from ground obstacles, allowing the blades to better capture wind energy, drive the generator to rotate, and convert wind energy into electrical energy, thus achieving efficient utilization of clean energy. The mounting plate 2 is used to connect the tower body 1, thereby transferring the stability of the adjustment component 4 and the limit component 5 to the tower body 1, improving the stability of the tower body 1. The connecting component 3 serves to connect the mounting plate 2 and the adjustment component 4. The setting of the adjustment component 4 enables the tower body 1 to be adapted to terrains with different slopes, thus making the tower body 1 adaptable to terrains with different slopes.

[0028] The adjusting assembly 4 includes a first mounting rod 41 disposed below the connecting assembly 3. A mounting base 42 is fixed to the outer side of the first mounting rod 41 by bolts. A second mounting rod 43 is fixed to the bottom of the mounting base 42. A limiting plate 44 is fixed to one end of the first mounting rod 41. The inner wall of the limiting plate 44 is slidably connected to the outer side of the second mounting rod 43, and a bolt for limiting the second mounting rod 43 is threadedly connected to the inner wall of the limiting plate 44.

[0029] The first mounting rod 41 is used to open the first screw hole 51 in the limiting assembly 5 so as to adjust the position of the mounting base 42 by bolts. The mounting base 42 is set to connect with the second mounting rod 43. The second mounting rod 43 is fixed to the bottom of the mounting base 42 and can slide in the limiting plate 44. The height can be adjusted by sliding to adapt to different terrains. The limiting plate 44 is fixed to one end of the first mounting rod 41, and its inner wall is slidably connected to the outer side of the second mounting rod 43. The second mounting rod 43 is limited by the threaded bolts so as to fix it when it is adjusted to a suitable position.

[0030] Example 2:

[0031] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the connecting component 3 includes a connecting shaft 31 threaded to the inner wall of the mounting plate 2, and a connecting seat 32 is fixed to the inner wall of the connecting shaft 31 by bolts.

[0033] The connecting shaft 31 is used for threaded connection with the mounting plate 2, and can also fix the connecting seat 32 to prevent it from shaking during operation. The connecting seat 32 is set to connect with the first mounting rod 41.

[0034] Specifically, the limiting component 5 includes multiple sets of first screw holes 51 opened on the inner wall of the first mounting rod 41, and multiple sets of second screw holes 52 opened on the inner wall of the second mounting rod 43, and both the first screw holes 51 and the second screw holes 52 are designed longitudinally.

[0035] Multiple sets of first screw holes 51 are used to adjust the position of the mounting base 42. Multiple sets of second screw holes 52 cooperate with the limiting plate 44, and the position of the second mounting rod 43 can be adjusted and fixed by tightening or loosening the bolts.

[0036] Specifically, the inner wall of the mounting base 42 is provided with a mounting groove 6, and a handle 7 is installed on the inner wall of the mounting groove 6.

[0037] The mounting slot 6 is used to fix the handle 7, providing a stable fixing space. When adjusting the mounting base 42, the handle 7 can be held to easily adjust the mounting base 42, thereby improving the convenience of adjustment.

[0038] Example 3:

[0039] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] Specifically, a positioning seat 8 is fixed to one end of the second mounting rod 43, and two sets of connecting rods 9 are fixed to the bottom of the positioning seat 8.

[0041] The positioning seat 8 and the mounting seat 42 have similar structural principles. The second mounting rod 43 can be adjusted by hand, which improves the convenience of adjustment. The connecting rod 9 is set to connect with the positioning seat 8.

[0042] Specifically, a connecting block 10 is fixed to one end of the connecting rod 9, and a pin 11 is threaded onto the inner wall of the connecting block 10.

[0043] The pin 11 is threaded to the inner wall of the connecting block 10. When the angle of the connecting block 10 is adjusted, it can be fixed by the pin 11 to ensure that there is no displacement after the angle is adjusted. Thus, the angle of the connecting rod 9 can be adjusted by the connecting block 10 to adapt to terrains with different slopes.

[0044] Specifically, the outer side of the pin 11 is threaded with two sets of base plates 12, and the bottom of the base plate 12 is fixed with a chassis 13.

[0045] The base plate 12 and the chassis 13 provide installation space for the pin 11 and support the overall device. The base plate 12 and chassis 13 are both set in three groups, and the stability of the triangle can support and fix the overall device.

[0046] During use, the positions of the three sets of adjustment components 4 are adjusted according to the terrain with different slopes to ensure the stability of the tower body 1 during operation. First, the bolts on the outside of the first mounting rod 41 and the limiting plate 44 are removed. At this time, the second mounting rod 43 and the mounting seat 42 are in a loose state. Then, the first mounting rod 41 is moved axially. When the mounting seat 42 moves, it drives the second mounting rod 43 to move. The second mounting rod 43 is slid to a suitable height and fixed by bolts through the threads on the inner wall of the limiting plate 44. At the same time, the multiple sets of first screw holes 51 on the inner wall of the first mounting rod 41 are used to fix it. Multiple sets of second screw holes 52 on the inner wall of the second mounting rod 43 allow for further fine-tuning and fixing of the position of the second mounting rod 43 by tightening and loosening the bolts, thus adapting to terrains with different slopes and maintaining the optimal verticality and windward angle of the tower body 1. At the same time, the mounting base 42 can be quickly adjusted using the handle 7. The positioning base 8 and two sets of connecting rods 9 are fixed at one end of the second mounting rod 43. After adjusting the angle of the connecting block 10, it is fixed with the pin 11. Finally, the two sets of base plates 12 and the base plate 13 are threaded to the outside of the pin 11, using the stability of the triangle to support and fix the entire device, making the tower adaptable to terrains with different slopes.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
