Referring to fig. 2 and fig. 3, in order to better ensure the safety performance of the wind turbine generator system provided by the embodiment of the present invention, the embodiment of the present invention further provides a novel guyed tower 100, which includes a tower body 10, a connecting assembly 20, and a guyed cable assembly 30, wherein the tower body 10 includes a plurality of tower cylinder sections 11 stacked along the axial direction X thereof, each tower cylinder section 11 includes a cylinder body 111 and end flanges 112 disposed at two ends of the cylinder body 111 in the axial direction X, and the end flanges 112 of two adjacent tower cylinder sections 11 are connected to each other.

Referring to fig. 4a to 4c, the connecting assembly 20 is disposed between two adjacent tower sections 11, the connecting assembly 20 includes a plurality of connecting lug seats 21 spaced apart from each other along a circumferential direction Y of the tower body 10, each connecting lug seat 21 includes a fixed section 211 and an adapter section 212 sequentially distributed along a radial direction Z of the tower body 10, two adjacent end flanges 112 commonly clamp and connect the fixed section 211, and the adapter section 212 protrudes from an outer edge of the tower body 10 and is provided with a connecting position 212a. In the circumferential direction Y, the adapter section 212 has a first edge 212b and a second edge 212c opposite to each other, and the minimum distance from the connection site 212a of at least one connection ear seat 21 to the first edge 212b of the same connection ear seat 21 is greater than the minimum distance to the second edge 212 c. The cable group 30 includes a plurality of cables 31 uniformly distributed and spaced in the circumferential direction Y, one end of each cable 31 is connected to one of the connecting lug seats 21 through the connecting position 212a, and the other end of each cable 31 is used for connecting a foundation, which may be a fan foundation 200, or may be a cable foundation (not shown) separately provided for connecting cables.

The embodiment of the invention provides the guyed tower 100, wherein the minimum distance from the connecting position 212a of at least one connecting lug seat 21 to the first edge 212b of the same connecting lug seat 21 is greater than the minimum distance from the connecting position to the second edge 212 c. The connection position 212a of the connection lug seat 21 is offset on the switching section 212 along the circumferential direction Y, after the guy cable 31 is connected, two parts of the connection lug seat 21 divided on the circumferential direction Y are in an asymmetric structure by taking the guy cable 31 as a boundary, so that even when a plurality of connection lug seats 21 cannot be uniformly distributed on the circumferential direction Y of the tower body 10, the defect that the plurality of connection lug seats 21 cannot be uniformly distributed on the tower body 10 can be made up through the offset connection position 212a, an included angle between every two adjacent guy cables 31 is the same, the plurality of guy cables 31 can be uniformly distributed on the circumferential direction Y of the tower, and further the strength and the bearing capacity of the guy cable type tower 100 are ensured.

As an alternative embodiment, the side of the adapting section 212 far from the fixing section 211 further includes a transition edge 212d connecting the first edge 212b and the second edge 212c, and a minimum distance from the connecting position 212a to the transition edge 212d in the force-receiving direction of the connected cable 31 is less than or equal to a minimum distance from the connecting position 212a to the first edge 212b of the same connecting ear seat 21. Through the above arrangement, on the basis of satisfying the uniform requirement of a plurality of guys 31 in circumference Y, the performance of connecting lug seat 21 can be optimized, so that connecting lug seat 21 has a longer service life.

In some optional embodiments, in the guyed tower 100 provided in each of the above embodiments, the connecting portion 212a may be a circular hole, the transition edge 212d is an arc-shaped surface and protrudes away from the fixed segment 211, a minimum distance from the connecting portion 212a to the transition edge 212d in the force-receiving direction is h1, a minimum distance from the connecting portion 212a to the first edge 212b is h2, and a minimum distance from the connecting portion 212a to the second edge 212c is h3, where: h1 is more than or equal to h2 and less than h3. Through the setting, the requirement of uniform distribution on the circumference Y of the inhaul cable 31 can be better met.

Meanwhile, when the cable 31 acts on the connecting lug seat 21, the damage of the connecting position 212a in the stress direction is the largest, and by limiting h1 to be not less than h2 and less than h3, as long as the position size of the connecting lug seat 21 with the largest damage meets the bearing requirement, even if the position of the connecting position 212a is offset, due to the size limitation, the connecting lug seat 21 can also meet the bearing requirement at each position after the connecting position 212a is offset.

Alternatively, the first edge 212b and the second edge 212c may be planar on the side where the transition edge is connected, one end of the first edge 212b is connected to one free end of the arc-shaped edge 212d and the other end of the first edge 212b extends toward the fixing section 211, one end of the second edge 212c is connected to the other free end of the arc-shaped edge 212d and the other end of the second edge 212c extends toward the fixing section 211. The distance between the first edge 212b and the second edge 212c in the radial direction Z and from the arc-shaped edge 212d to the side of the fixed section 211 may be set in a gradually increasing manner.

As an alternative implementation manner, in the guyed tower 100 provided in each of the above embodiments, the fixing section 211 and the transition section 212 have a plate-shaped structure, respectively, and are simple in structure and easy to install. Optionally, the fixed section 211 and the transition section 212 may be connected by a circular arc transition, so as to reduce stress concentration.

Optionally, a lubricating sleeve may be disposed inside the connection position 212a, so that abrasion of the cable 31 to the connection position 212a can be effectively reduced, and the service life of the connection lug 21 is prolonged.

Optionally, the stay cable tower 100 further includes a fastener 12, and the flange holes 112a of two adjacent end flanges 112 are oppositely disposed and connected by the fastener 12. The fixing section 211 of each connecting lug seat 21 is provided with two or more fixing holes 211a, the two or more fixing holes 211a are arranged at intervals in the circumferential direction Y, and each fixing hole 211a is arranged opposite to the flange hole 112a in the axial direction X and is connected to the end flange 112 through a fastener 12. Through the arrangement, the connection lug seat 21 can be more conveniently disassembled and assembled, the connection between the inhaul cable 31 and the tower body 10 is met, and meanwhile, the strength of the connection lug seat 21 can be ensured.

Alternatively, the number of the fixing holes 211a included in the fixing section 211 of each connecting assembly 20 is not particularly limited, and may be two, three or more, as long as the requirement of the connection strength between the guy cable 31 and the tower body 10 can be met, and the safety and stability of the whole guy cable type tower 100 can be ensured.

Optionally, the fixing sections 211 of the connecting lug seats 21 may have the same structure, and through the above arrangement, the universality of the connecting lug seats 21 can be ensured as much as possible from the aspect of process processing, so that the stay cable tower 100 has better economic benefit.

Referring to fig. 5 and fig. 6 together, as an alternative implementation manner, in the guyed tower 100 provided in the above embodiments, the number of the flange holes 112a included in each end flange 112 is M, the number of the connecting lug seats 21 is N, wherein a ratio of M to N is a non-integer, each two adjacent connecting lug seats 21 are in one group, in the circumferential direction Y, an included angle between one group of the connecting lug seats 21 is larger than an included angle between the other group of the connecting lug seats 21, or each two adjacent connecting lug seats 21 are in one group, in the circumferential direction Y, the number of the flange holes 112a between one group of the connecting lug seats 21 is larger than the number of the flange holes 112a between the other group of the connecting lug seats 21.

With the above arrangement, when the number of the flange holes 112a on the end flange 112 included in the tower body 10 is not an integral multiple of the number of the connecting lug seats 21, the included angle between two adjacent connecting lug seats 21 can be adjusted, so that the plurality of connecting lug seats 21 are arranged in a non-uniform manner in the circumferential direction Y to meet the requirement of detachable connection between the fastening members 12 for connecting the end flange 112 and the tower body 10. Meanwhile, the connection position 212a of at least one connection lug seat 21 is offset, so that the defect that the plurality of connection lug seats 21 cannot be uniformly distributed on the tower can be overcome, the plurality of guys 31 can be uniformly distributed in the circumferential direction Y of the tower, and the strength and the bearing capacity of the guy cable type tower 100 are ensured.

Referring to fig. 4a to 8c, in order to better understand the embodiment of the present invention, the connecting assembly 20 includes three connecting lug seats 21, the number of the flange holes 112a of each end flange 112 is 80, and each connecting lug seat 21 is provided with 5 fixing holes 211a corresponding to the flange holes 112 a. Since the number of the flange holes 112a is not an integral multiple of the number of the connecting lug seats 21, if the connecting lug seats 21 are connected to the tower body 10 through the fastening members 12 connecting the two end flanges 112, the connecting lug seats 21 need to be arranged non-uniformly in the circumferential direction Y, for example, the included angles of two adjacent connecting lug seats 21 in the circumferential direction may be 121.5 °, 117 ° and 121.5 ° in sequence.

At this time, two of the three connecting lug seats 21, namely, the two connecting lug seats 21 shown in fig. 4a to 4c and fig. 8a to 8c, may be configured asymmetrically in the circumferential direction Y, and the connecting lug seats 21, which are respectively at 121.5 ° with the other two connecting lug seats 21, may be configured symmetrically in the circumferential direction Y with the connecting position 212a as a boundary, namely, the configuration shown in fig. 7a to 7 c. That is, the minimum distance from the connecting position 212a of the connecting ear seat 21 to the first edge 212b thereof may be equal to the minimum distance to the second edge 212c, i.e., h2= h3. And two connecting lug seats 21 with an included angle of 117 degrees can adopt an asymmetric structure in the circumferential direction Y, so that the connecting positions 212a of the two connecting lug seats are close to the side of the connecting lug seat 21 with the symmetric structure in the circumferential direction Y, and further a plurality of pull cables 31 connected with the connecting lug seats 21 can be uniformly distributed at an angle of 120 degrees in the circumferential direction Y.

The above and the following said included angles between two adjacent connecting ear seats 21 refer to: the angle between the center lines of the connecting lug seats 21 in the circumferential direction Y. For example, when the number of the fixing holes 211a is odd, the center line of the connecting lug seat 21 in the circumferential direction Y may refer to: a line perpendicular to the axis of the tower body 10 in the circumferential direction Y at the middle, i.e. the center of the third fixing hole 211a in this example.

If the number of the coupling hole fixing holes 211a is an even number, the center line of the coupling lug seat 21 in the circumferential direction Y means: a line passing through the midpoint of the center connecting line of the two most middle fixing holes 211a in the circumferential direction Y and perpendicular to the axis of the tower body.

It is to be understood that the above-described embodiments are illustrative of the present invention for the best understanding of the embodiments. For example, the number of the connecting lug seats 21 is three, the number of the flange holes 112a included in each end flange 112 is 50, 3 fixing holes 211a corresponding to the flange holes 112a are provided in each connecting assembly 20, and the number of the flange holes 112a is not an integral multiple of the number of the connecting lug seats 21. The included angles of the three connecting lug seats 21 in the circumferential direction Y can be distributed at 122.4 °, 122.4 ° and 115.2 °. And two of the connecting lug seats 21 can adopt an asymmetric structure in the circumferential direction Y, so that the connecting positions 212a are arranged in an offset manner, the offset angle of each connecting position 212a on the two connecting lug seats 21 can be set according to parameters such as the size of the tower, and the like, as long as the guys 31 connected with each connecting lug seat 21 of the connecting assembly 20 can be uniformly distributed in the circumferential direction Y, that is, the included angle between two adjacent guys 31 can be 120 °.
