[0002] In the fields of wind power generation, communication base stations, and other fields that require high-rise structures, the tower barrel, as an important component supporting the entire system, its stability and precise centering are crucial. Traditionally, during the installation process, the centering of the tower barrel and the base is an extremely delicate and crucial task; due to the height, weight of the tower barrel, and the complexity of the environment where it is located, this step is full of uncertainties; traditional methods often rely on manual operations, and experienced workers need to continuously adjust and correct to ensure that the plumb line of the tower barrel and the base perfectly coincide. This process is not only time-consuming and laborious but also extremely vulnerable to human factors, resulting in difficult-to-guarantee centering accuracy. Summary of the Invention

[0003] The purpose of the present invention is to provide a bottom mounting device for wind power equipment, which can solve the problems raised in the background art.

[0004] According to the technical solution provided by the present invention: a bottom mounting device for wind power equipment includes a tower barrel and a base plate. At least two second screws are provided on the base plate, and a support semi-ring is jointly provided on every two second screws. A support rod is provided on the support semi-ring. A support plate is provided on the connecting plate, and four support plates enclose a circle. A push plate is provided between the opposite sides of the support plates. The push plate and the support plate are connected by an elastic component. The push plate is attached to the outer side of the tower barrel, and under the support of the four push plates, the plumb line of the tower barrel and the plumb line of the circle enclosed by the four support plates are on the same line to ensure that the plumb line of the tower barrel is consistent with the plumb line of the base plate.

[0005] Preferably, the elastic component includes a guide rod and a second spring; a second spring is provided between the push plate and the support plate. One end of the guide rod is connected to the push plate, and the other end extends out of the support plate, and the second spring is sleeved on the outer side of the guide rod.

[0006] Preferably, the upper end of the push plate is bent outward, and a plurality of rollable rollers are embedded on the opposite sides of the push plate, and the plurality of rollers are distributed vertically.

[0007] Preferably, four flat grooves are opened on the outer wall of the tower barrel, and the rollers are in contact with the flat grooves. Two limiting plates are provided on the push plate, and the maximum distance between the two limiting plates is the same as the width of the flat groove to ensure that the limiting plates are located in the flat grooves during operation.

[0008] Preferably, a first threaded hole is formed in the substrate, a first spring is arranged in the first threaded hole, and a round cover is arranged at the upper end of the first spring; the second screw rod is screwed with the first threaded hole, and the lower end of the second screw rod contacts the round cover.

[0012] The bottom mounting device of a wind power device provided by an embodiment of the present invention has the following advantages:

[0013] 1. Under the combined support of the four push plates, the vertical center line of the tower barrel is adjusted to be on the same straight line as the vertical center line of the circular structure surrounded by the four support plates. This alignment not only ensures the stability of the tower barrel in the vertical direction, but also further ensures that the vertical center line of the tower barrel is consistent with the vertical center line of the substrate.

Specific embodiments

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0024] As Figures 1-6 shown, the present invention is a bottom mounting device for a wind power device, including a tower barrel 1 and a base plate 2. The base plate 2 is circular, and four second screws 3 are equidistantly arranged on the base plate 2. A support semi-ring 31 is jointly arranged on every two second screws 3. Two support semi-rings 31 enclose a circle. Two support rods 32 are arranged on each support semi-ring 31. The support rods 32 are in a V shape. A support plate 33 is arranged on the support rods 32. Four support plates 33 enclose a circle;

[0025] Push plates 36 are arranged between the opposite sides of the support plates 33. The push plates 36 and the support plates 33 are connected by an elastic component. The four push plates 36 enclose a circle at the same time for facilitating the cooperation with the tower barrel 1. The push plates 36 are attached to the outer side of the tower barrel 1. Under the support of the four push plates 36, the vertical line of the tower barrel 1 and the vertical line of the circle enclosed by the four support plates 33 are on the same line to ensure that the vertical line of the tower barrel 1 is consistent with the vertical line of the base plate 2.

[0026] A push plate 36 is arranged between the opposite sides of the support plate 33. The push plate 36 plays a supporting role, and an elastic component is arranged between the push plate 36 and the support plate 33 to form an interconnected structure. This elastic connection method endows the push plate 36 with a certain degree of mobility and self-adaptive ability, enabling them to make appropriate adjustments according to actual needs, so as to better adapt to different sizes of the tower barrel 1.

[0027] The four push plates enclose a circular structure, which can perfectly match the outer contour of the tower barrel 1. When the tower barrel 1 is placed inside this circular structure, the four push plates 36 can evenly fit on the outer side wall of the tower barrel 1, providing stable and balanced supporting force.

[0028] Under the combined support of the four push plates 36, the vertical line of the tower barrel 1 is adjusted to be on the same straight line as the vertical line of the circular structure enclosed by the four support plates 33. This alignment not only ensures the stability of the tower barrel 1 in the vertical direction but also further guarantees that the vertical line of the tower barrel 1 is consistent with the vertical line of the base plate 2. This consistency is crucial for ensuring the stability and safety of the entire structure, especially in application scenarios such as wind power generation that require highly precise alignment, and is even indispensable.

[0029] In summary, through the ingenious combination of the push plate 36 and the elastic component, as well as the circular structure formed by the four push plates, the entire system not only realizes the effective support and stable fixation of the tower barrel 1 but also ensures the precise alignment between the tower barrel 1 and the base plate 2, laying a solid foundation for subsequent installation and use.

[0030] Preferably, the elastic component includes a guide rod 34 and a second spring 35; a second spring 35 is arranged between the push plate 36 and the support plate 33. One end of the guide rod 34 is connected to the push plate 36, and the other end extends out of the support plate 33, and the second spring 35 is sleeved outside the guide rod 34; through the arrangement of the guide rod 34 and the second spring 35, the second spring 35 endows the push plate 36 with a certain degree of mobility and self-adaptive ability, enabling them to make appropriate adjustments according to actual needs, so as to better adapt to different sizes of the tower barrel 1. The setting of the guide rod 34 ensures that the second spring 35 will not deform during stretching and resetting.

[0031] Preferably, the upper end of the push plate 36 bends outward, and a plurality of rollable rollers 37 are embedded on both opposite sides of the push plate 36, and the plurality of rollers 37 are distributed vertically; four flat grooves 11 are opened on the outer wall of the tower barrel 1, and the rollers 37 are in contact with the flat grooves 11. Two limit plates 38 are arranged on the push plate 36, and the maximum distance between the two limit plates 38 is the same as the width of the flat groove 11 to ensure that the limit plates 38 are located inside the flat groove 11 during operation.

[0032] The upper end of the push plate 36 is bent outward, enabling the tower barrel 1 to quickly enter the four push plates 36. The introduction of the rolling rod 37 not only reduces the friction between the push plate 36 and the outer wall of the tower barrel 1, making the whole structure smoother during adjustment or movement, but also improves the overall durability and service life. More importantly, this design enables the push plate 36 to better adapt to the minor unevenness on the surface of the tower barrel 1, ensuring a stable supporting effect.

[0033] To further optimize the cooperation between the push plate 36 and the tower barrel 1, four flat grooves 11 are opened on the outside of the tower barrel 1. The design dimensions of these flat grooves 11 match the diameter and arrangement of the rolling rods 37. When the rolling rods 37 on the push plate 36 come into contact with the flat grooves 11 of the tower barrel 1, they can be tightly embedded therein, further enhancing the fixing effect of the push plate 36 on the tower barrel 1.

[0034] More ingeniously, two limiting plates 38 are also provided on the push plate 36. The maximum distance between the two limiting plates 38 is precisely set to be the same as the width of the flat groove 11. This design ensures that the limiting plates 38 can be stably located within the flat groove 11 during operation, preventing the push plate 36 from shaking in the vertical direction and enhancing the connection stability between the push plate 36 and the tower barrel 1.

[0035] At the same time, when the limiting plates 38 are located within the flat groove 11 and form a good fit, at this time, the positions of the screw holes on the base ring 12 and the first screw 21 are exactly in perfect alignment, making full use of the stability and precision provided by the cooperation between the limiting plates 38 and the flat groove 11, laying a solid foundation for the smooth progress of the subsequent steps.

[0036] As the tower barrel 1 is slowly lowered in the vertical direction, the screw holes on the base ring 12 and the first screw 21 gradually approach until they are completely aligned, marking the stable connection between the tower barrel 1 and the base ring 12, eliminating the need for staff adjustment and improving the working effect.

[0037] Preferably, a first threaded hole 22 is opened on the base plate 2. A first spring 23 is provided in the first threaded hole 22, and a round cover 24 is provided at the upper end of the first spring 23. The second screw 3 is screwed into the first threaded hole 22, and the lower end of the second screw 3 contacts the round cover 24. The connection of screwing the second screw 3 into the first threaded hole 22 enables the quick installation and disassembly of the support semi-ring 31. The settings of the first spring 23 and the round cover 24 prevent external dust and impurities from entering the first threaded hole 22 when the first threaded hole 22 is not in use, ensuring the cleanliness of the first threaded hole 22 and thereby improving the service life of the first threaded hole.

[0038] Preferably, both ends of the support semi-ring 31 are provided with connecting plates 311, and two second threaded holes 312 are formed in each of the connecting plates 311. A bolt 313 is screwed into the second threaded hole 312 on one side, and the bolt 313 is screwed into the second threaded hole 312 on the other side, so that the two support semi-rings 31 form an integral body.

[0039] Preferably, a base ring 12 is provided at the lower end of the tower barrel 1, and two groups of screw holes are formed in the base ring 12; two groups of first screw rods 21 are provided on the base plate 2, and the first screw rods 21 are all matched with the screw holes.

[0040] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
