[0030] The present application provides a tower barrel assembly of a wind turbine, which includes a tower barrel and accessories arranged inside the tower barrel. The accessories include a bracket, a first cable clamp block, and a second cable clamp block arranged at the top of the tower barrel. The bracket is connected to the tower barrel and includes a first connection part and a second connection part that are staggered in the height direction of the tower barrel. The first cable clamp block is connected to the first connection part, and the second cable clamp block is connected to the second connection part. With such an arrangement, the first cable clamp block and the second cable clamp block can be staggered in the height direction of the tower barrel, so that the space in the height direction of the tower barrel can be better utilized, the space at the same height inside the tower barrel can be saved, and the installation difficulty is reduced compared with the case where the first cable clamp block and the second cable clamp block are arranged at the same height inside the tower barrel, thus solving the problem of limited space at the top inside the tower barrel. In addition, compared with the solution of solving the problem of limited top space by changing the cable routing on the top platform of the tower barrel, the construction cost is reduced and the construction period is shortened.

[0031] Figure 1 The partial structural schematic diagram of the tower barrel assembly 1 is shown. The tower barrel assembly 1 includes a tower barrel 2 and accessories 3 arranged inside the tower barrel 2. The tower barrel 2 can be set as a tower barrel with a taper, and the cross-section of the tower barrel 2 gradually decreases from the bottom to the top. The accessories 3 include a bracket 4 fixedly connected to the tower barrel 2 and a ladder 5 connected to the bracket 4. The ladder 5 facilitates the construction personnel to climb for operations such as maintenance and inspection.

[0032] The ladder rack 5 includes a first longitudinal beam 6 and a second longitudinal beam 7 that extend in the height direction and are parallel to each other, and a plurality of cross beams 8 that are connected between the first longitudinal beam 6 and the second longitudinal beam 7 and are spaced apart; on the side of the first longitudinal beam 6 and the second longitudinal beam 7 close to the center of the tower barrel 2, there is an elevator guide rail 10 for the elevator 9 to lift. In this embodiment, the bracket 4 is connected between the ladder rack 5 and the barrel wall of the tower barrel 2 and serves as a bridge for fixing the ladder rack 5 to the barrel wall, playing a role in stabilizing the ladder rack 5. The ladder rack 5 is supported on the bottom of the tower barrel 2 through the first longitudinal beam 6 and the second longitudinal beam 7, and a plurality of cross beams 8 are arranged between the first longitudinal beam 6 and the second longitudinal beam 7 to facilitate the climbing of construction workers. In addition, an elevator guide rail 10 is arranged on the side of the ladder rack 5 close to the center of the tower barrel 2, and the elevator guide rail 10 is used to install the elevator 9. An elevator 9 is arranged on one side of the cross beam 8, and on the other side, together with the bracket 4 and the barrel wall, it encloses a space for construction workers to pass through. In this way, the ladder rack 5 serves as both an elevator guide rail 10 and a climbing ladder, and the lifting of the elevator 9 and the climbing of construction workers do not interfere with each other, capable of meeting multi-scenario applications. In some embodiments, the tower barrel 2 is a conical tower barrel with a large bottom and a small top. The closer to the top of the tower barrel 2, the closer the first longitudinal beam 6 and the second longitudinal beam 7 are to the center position of the tower barrel 2. In this embodiment, the first longitudinal beam 6 and the second longitudinal beam 7 are inclined upward from bottom to top in the direction of the central axis of the tower barrel 2, so that there is enough climbing clearance between the ladder rack 5 and the inner wall of the tower barrel 2, avoiding the climbing clearance becoming smaller and smaller as the climbing height increases. In addition, in some embodiments, the horizontal distance between the ladder rack 5 and the barrel wall is greater than 650 mm to meet the climbing requirements of construction workers.

[0033] In some embodiments, the first longitudinal beam 6 includes a plurality of first longitudinal beam segments connected in sequence along the height direction of the tower barrel 2. The second longitudinal beam 7 includes a plurality of second longitudinal beam segments connected in sequence along the height direction of the tower barrel 2. The supplementary angle of the angle between two adjacent first longitudinal beam segments is less than or equal to 0.5°. The supplementary angle of the angle between two adjacent second longitudinal beam segments is less than or equal to 0.5°. The angles between the first longitudinal beam segment and the second longitudinal beam segment at the same height and the horizontal plane are the same. In this embodiment, the first longitudinal beam 6 includes a plurality of first longitudinal beam segments, and the second longitudinal beam 7 includes a plurality of second longitudinal beam segments. The plurality of first longitudinal beam segments and the plurality of second longitudinal beam segments are respectively parallel to each other one by one. It should be noted that theoretically, designing the supplementary angle of the angle between two adjacent first longitudinal beam segments to be less than 1°, and designing the supplementary angle of the angle between two adjacent second longitudinal beam segments to be less than 1°, such that the deflection angles of two adjacent first longitudinal beam segments and two adjacent second longitudinal beam segments are relatively small and are not prone to breakage, making the overall stability of the ladder rack 5 better. However, considering various construction errors and the like, in a preferred embodiment, the supplementary angle of the angle between two first longitudinal beam segments is set to be less than or equal to 0.5°, and the supplementary angle of the angle between two adjacent second longitudinal beam segments is set to be less than or equal to 0.5°, so as to reserve 0.5° to absorb the influence of various errors.

[0034] Figure 2 is Figure 1 a partial schematic view of the top of the tower barrel assembly 1 shown in the figure. As Figure 2 shown, the accessory 3 includes a first cable clamp block 11 and a second cable clamp block 12; the bracket 4 is connected to the tower barrel 2 and includes a first connection part 13 and a second connection part 14 that are offset in the height direction of the tower barrel 2. The first cable clamp block 11 is connected to the first connection part 13, and the second cable clamp block 12 is connected to the second connection part 14. The connection method between the first connection part 13 and the first cable clamp block 11 and the connection method between the second connection part 14 and the second cable clamp block 12 include but are not limited to bolt connection. In this solution, since the heights of the first connection part 13 and the second connection part 14 are different, the space in the height direction of the tower barrel 2 can be better utilized, the space inside the tower barrel 2 at the same height can be saved, and the installation difficulty is reduced compared with setting the first cable clamp block 11 and the second cable clamp block 12 at the same height inside the tower barrel 2, solving the problem of limited space at the top inside the tower barrel 2. In addition, compared with the solution of solving the problem of limited top space by changing the cable routing on the top platform of the tower barrel 2, the construction cost is reduced and the construction period is shortened.

[0035] In one embodiment, the first cable clamp block 11 and the second cable clamp block 12 are used to fix the cable. For example, the first cable clamp block 11 is used to clamp the main cable, and the second cable clamp block 12 is used to clamp the power supply cable.

[0036] For the tower barrel 2 with a taper, since the barrel diameter at the bottom of the tower barrel 2 is large and the space is not limited, the first cable clamp block 11 and the second cable clamp block 12 can be set at the same height. That is to say, the first cable clamp block 11 and the second cable clamp block 12 can be arranged side by side at the same height.

[0037] In some embodiments, along the height direction of the tower barrel 2, a plurality of brackets 4 can be arranged at the top of the tower barrel 2. Correspondingly, a plurality of the first cable clamp blocks 11 and the second cable clamp blocks 12 are respectively arranged. The first cable clamp block 11 and the second cable clamp block 12 that are offset in the height direction are connected to each bracket 4. With such an arrangement, the same cable can be clamped by a plurality of the first cable clamp blocks 11 in the height direction, and the same cable can be clamped by a plurality of the second cable clamp blocks 12 in the height direction, ensuring that the cable is reliably constrained inside the tower barrel 2 and improving the stability of the cable routing.

[0038] In an alternative embodiment, a plurality of the first cable clamp blocks 11 located on different brackets 4 are aligned in the height direction of the tower barrel 2, and a plurality of the second cable clamp blocks 12 located on different brackets 4 are aligned in the height direction of the tower barrel 2. In this way, the degree of torsion or bending when the cable is routed can be reduced, ensuring that the cable extends in the same direction and reducing the risk of cable damage.

[0039] Figure 3 for Figure 1 A partial schematic diagram of an angle below the top of the tower assembly 1 is shown. Figure 2 and Figure 3 As shown, the tower 2 includes a plurality of tower sections 30 stacked in the height direction, and the tower section 30 located at the uppermost end is defined as the top of the tower 2. In the uppermost tower section 30, the first cable clamp block 11 and the second cable clamp block 12 are arranged at different heights (such as Figure 2 In the remaining tower sections 30, the first cable clamp block 11 and the second cable clamp block 12 may be arranged at the same height (as shown in FIG. Figure 3 ). Tower sections include but are not limited to tower sections made of concrete.

[0040] Figure 4 for Figure 1 FIG. 1 is a schematic diagram of a partial structure of the tower assembly 1 from another angle below the top. Figure 4 As shown, in some embodiments, the bracket 4 is fixed to the cross beam 8 by a clamping plate 26. In some embodiments, along the radial direction of the tower 2, the bracket 4 may include a first sub-bracket 40 and a second sub-bracket 41 arranged in parallel with each other, which are respectively connected to the two ends of the cross beam 8 by the clamping plate 26, so that the ladder frame 5 is balanced in the lateral direction, so that the connection with the cylinder wall is more stable.

[0041] Continue to refer Figure 2 As shown, in some embodiments, the first cable clamp block 11 and the second cable clamp block 12 are staggered along the circumference of the tower 2. In other words, in the circumference of the tower 2, the first cable clamp block 11 and the second cable clamp block 12 are spaced apart, so that the first cable clamp block 11 and the second cable clamp block 12 can be prevented from overlapping in the height direction, and there is no need to change the direction of the cables at the top platform of the tower 2, so that the cables are always routed in the vertical direction at the top of the tower 2.

[0042] In some embodiments, the first cable clamp block 11 is provided with a first cable hole 110 for cables to pass through, and the second cable clamp block 12 is provided with a second cable hole 120 for cables to pass through, and the number of the first cable holes 110 is greater than the number of the second cable holes 120. In this embodiment, the first cable holes 110 are for main cables to pass through, and the second cable holes 120 are for power cables to pass through. Since the number of main cables is relatively large, the number of the first cable holes 110 needs to be greater than the number of the second cable holes 120 to meet the need of passing through multiple main cables.

[0043] In some embodiments, the bracket 4 is connected between the side of the ladder frame 5 facing away from the elevator guide rail 10 and the barrel wall of the tower barrel 2. In this embodiment, the bracket 4 and the elevator guide rail 10 are not on the same side of the ladder frame 5, so that the first cable clamp block 11 and the second cable clamp block 12 mounted on the bracket 4 and the elevator 9 mounted on the elevator guide rail 10 are not on the same side of the ladder frame 5. Thus, interference between the first cable clamp block 11 and the second cable clamp block 12 and the elevator 9 is avoided.

[0044] Figure 5 For Figure 2 the partial top view of the top of the tower barrel assembly 1 shown. In combination with Figure 2 , Figure 5 shown, in some embodiments, the accessory 3 includes a top platform 15 fixed to the top of the tower barrel 2 and a platform cover plate 16 movably arranged on the top platform 15; the top platform 15 is arranged in the uppermost tower barrel section, the top platform 15 includes a notch 17, the notch 17 faces the ladder frame 5, and the platform cover plate 16 covers the notch 17, and the notch 17 can be opened and closed by moving the platform cover plate 16. Among them, the shape of the surface of the platform cover plate 16 facing the tower barrel 2 coincides with the shape of the inner surface of the tower barrel 2. In this embodiment, when the construction worker climbs along the ladder frame 5 to the top platform 15, they can enter the top platform 15 through the notch 17. And, after the construction is completed, the platform cover plate 16 is covered above the notch 17 to block the notch 17, so that the top platform 15 is completely circumferentially laid, so as to reduce the risk of falling objects from height and the risk of construction workers falling. The shape of the side edge of the platform cover plate 16 close to the barrel wall coincides with the shape of the barrel wall to reduce the gap between the platform cover plate 16 and the barrel wall and improve safety. In some embodiments, the shape of the side edge of the platform cover plate 16 close to the barrel wall is arc-shaped and the same as the inner contour shape of the barrel wall. In some embodiments, the platform cover plate 16 is rotatably connected to the top platform 15, with a simple structure and convenient to open. A handle 20 can be arranged on the platform cover plate 16 to facilitate the construction worker to open and close the platform cover plate 16 through the handle 20.

[0045] In some embodiments, the platform cover plate 16 includes a base plate 18 and a side plate 19 connected to the base plate 18 and close to the tower barrel 2. The side plate 19 extends along the inner wall of the tower barrel 2 around the center of the tower barrel 2 and is adjacent to the inner wall of the tower barrel 2. In this embodiment, a side plate 19 is connected to the side edge of the platform cover plate 16 close to the barrel wall, and the side plate 19 extends vertically upward to play a role in safety protection. And, the length of the side plate 19 matches the length of the side edge of the corresponding platform cover plate 16 close to the barrel wall, so as to reduce the gap between the side plate 19 and the top platform 15 in the circumferential direction of the top platform 15 and improve the safety protection.

[0046] Figure 6 For Figure 2Partial structural schematic diagram of a certain angle at the top of the tower barrel assembly 1 shown. As Figure 6 shown, in some embodiments, the height of the first connection part 13 where the first cable clamp block 11 is located is higher than the height of the second connection part 14 where the second cable clamp block 12 is located, which makes the first cable clamp block 11 higher than the second cable clamp block 12; the platform cover plate 16 is connected to the first connection part 13, flush with the height of the first cable clamp block 11, and the platform cover plate 16 and the first cable clamp block 11 are connected to different sides of the first connection part 13. In this embodiment, the platform cover plate 16 covers the upper part of the notch 17, and one end can be connected to the first connection part 13 through a hinge. The first cable clamp block 11 is arranged on the side of the first connection part 13 and is located outside the notch 17. In this way, the platform cover plate 16 and the first cable clamp block 11 are respectively connected to both sides of the first connection part 13, avoiding interference between the platform cover plate 16 and the first cable clamp block 11 when the platform cover plate 16 flips and providing enough moving space for the platform cover plate 16.

[0047] Figure 7 For Figure 2 partial structural schematic diagram of another angle at the top of the tower barrel assembly 1 shown. Combining Figure 2 , Figure 7 shown, in some embodiments, one end of the bracket 4 is connected to the tower barrel 2, and the other end is connected to the ladder 5. The bracket 4 is set as a plate body with a plane of a set area, which is convenient for installing the first cable clamp block 11 and the second cable clamp block 12.

[0048] The bracket 4 includes a first connecting plate 24 and a second connecting plate 25. The plate surfaces of the first connecting plate 24 and the second connecting plate 25 are both placed vertically. The first cable clamp block 11 is vertically installed on the plate surface of the first connecting plate 24, and the second cable clamp block 12 is vertically installed on the plate surface of the second connecting plate 25, so that the first connecting plate 24 and the second connecting plate 25 can bear a large bending moment and reduce the risk of deformation of the first connecting plate 24 and the second connecting plate 25.

[0049] The first connecting plate 24 is connected to one side of the ladder 5, and the upper end of the first connecting plate 24 is set as the first connection part 13. The second connecting plate 25 is a bent plate, one end is connected to the lower end of the first connecting plate 24, and the other end is a free end. The second connecting plate 25 extends from one side of the first connecting plate 24 and bends towards the side of the ladder 5 opposite to the first connecting plate 24, and the free end is set as the second connection part 14. The first connecting plate 24 and the second connecting plate 25 are located on different sides of the ladder 5, so that the first cable clamp block 11 and the second cable clamp block 12 are located on different sides of the ladder 5 to avoid interference in the cable routing of the cables respectively clamped by the first cable clamp block 11 and the second cable clamp block 12 and reduce the risk of cable damage. And, one end and the other end of the second connecting plate 25 are bent and stagger - arranged in the horizontal direction to save the installation space of the second connecting plate 25.

[0050] Please continue to refer to Figure 2 、 Figure 7 As shown, in some embodiments, there is a set space between the free end of the second connecting plate 25 and the elevator guide rail 10 installed on the first longitudinal beam 6, so as to prevent the elevator guide wheel 90 installed on the elevator guide rail 10 from touching the free end of the second connecting plate 25 when sliding up and down, thereby also avoiding the elevator guide wheel 90 from touching the second cable clamp block 12.

[0051] In some embodiments, the tower barrel 2 is made of concrete. The tower barrel assembly 1 further includes a buried part 23 embedded in the tower barrel 2. The first connecting plate 24 is connected to the buried part 23. In the orthographic projection along the height direction of the tower barrel 2, the projection area of the first cable clamp block 11 partially coincides with the projection area of the buried part 23. In this embodiment, both the first cable clamp block 11 and the buried part 23 are connected to the same side of the first connecting plate 24. In the height direction of the first connecting plate 24, by setting the first cable clamp block 11 to be staggered from the buried part 23, in this way, the horizontal connection space of the first connecting plate 24 can be saved, and thus the horizontal space between the ladder frame 5 and the cylinder wall is also shortened.

[0052] In some embodiments, the buried part 23 includes a third connecting plate 22 and a buried pipe 29. The third connecting plate 22 is connected to the first connecting plate 24. A connecting hole 27 is provided at the connection between the third connecting plate 22 and the first connecting plate 24, and it is connected to the first connecting plate 24 by bolts or the like, but not limited thereto. In some embodiments, the connecting hole 27 is a waist-shaped hole with a set length, so that the connection position between the third connecting plate 22 and the first connecting plate 24 can be changed according to actual construction needs, so as to facilitate the construction personnel to overall plan the horizontal distance from the ladder frame 5 to the cylinder wall. In some embodiments, the length specifications of the third connecting plate 22 can include 3 kinds, 4 kinds, 5 kinds, 6 kinds, etc. In this embodiment, it is preferably 3 - 4 kinds, which is reduced compared with the traditional length specifications of the third connecting plate 22. And, the length dimension difference between two adjacent length specifications of the third connecting plate 22 is 40 mm - 50 mm, which is beneficial to on-site construction distinction and improves construction efficiency. In some embodiments, the third connecting plate 22 is made of channel steel. In some embodiments, the length of the connecting hole 27 is 40 - 50 mm.

[0053] In some embodiments, one end of the buried pipe 29 facing away from the third connecting plate 22 is poured into the cylinder wall, and the other end of the buried pipe 29 facing the third connecting plate 22 is connected to the third connecting plate 22 by bolts. It should be noted that during the pouring process of the buried pipe 29, it is necessary to adjust the third connecting plate 22 and the first connecting plate 24 to be perpendicular to each other. In this way, there is only one angle specification for the third connecting plate 22, so as to avoid the construction personnel on site from making distinction mistakes due to too many angle specifications of the third connecting plate 22.

[0054] In some embodiments, the third connecting plate 22 is bent on the side facing away from the first connecting plate 24, so as to facilitate the connection between the end of the embedded pipe 29 facing away from the cylinder wall and the third connecting plate 22.
