Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, and particularly relates to a fixing device for inner accessories in a floating wind turbine tower barrel. Background Art

[0002] Due to limited offshore development resources, strong ecological constraints, high demands for other economic activities, and relatively scattered sites, the development of offshore wind power towards the deep sea is an inevitable trend. As a powerful tool for the wind power industry to move towards the deep sea, the structure of a floating wind turbine is different from that of a traditional "fixed" offshore wind turbine, resulting in some problems to be solved. Among them, because the load of a floating wind turbine is relatively large, in order not to excessively increase the weight of the tower barrel, the fatigue grade of the tower barrel weld is increased to the highest requirement. However, the welds of some inner accessories in the tower barrel cannot meet this requirement, so the conventional welding method cannot be used to fix the inner accessories. Therefore, a new fixing device for inner accessories in a floating wind turbine tower barrel is urgently needed. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide a fixing device for inner accessories in a floating wind turbine tower barrel, which will not increase the weight of the tower barrel.

[0009] Further, the hanger assembly includes a plurality of support rods, and the plurality of support rods are cross-fixed to form the hanger assembly.

[0010] Further, the connecting part includes a thimble and a lifting buckle. A lifting ring corresponding to the lifting buckle is arranged on the flange. The lifting buckle can be buckled with the lifting ring. The thimble is connected between the lifting buckle and the steel wire rope, and the thimble can tighten the steel wire rope.

[0011] Further, the connecting assembly includes positioning sleeves. A plurality of positioning sleeves are fixedly arranged on the steel wire rope at intervals from top to bottom. The positioning sleeves can be fixed type or detachable type. A plurality of upper-small-and-lower-large notches corresponding to the positioning sleeves are formed on each hanger assembly. The steel wire rope can be clamped into the upper part of the notch, and the positioning sleeve can be clamped in the lower part of the notch.

[0012] Further, the adjusting and supporting assembly includes a plurality of adjusting and supporting assemblies. The plurality of adjusting and supporting assemblies are circumferentially arranged on the hanger assembly at intervals, and the adjusting and supporting assembly can adjust the length along the radial direction of the hanger assembly and can support on the inner wall of the cylinder section.

[0013] Further, each adjusting and supporting assembly includes a screw rod and a pressing plate fixed at the end of the screw rod. The screw rod is in threaded connection with the hanger assembly. By rotating the screw rod, the pressing plate can be driven to abut against the inner wall of the cylinder section.

[0014] Advantages of the present utility model:

[0015] When the fixing device for the internal accessories in the floating wind turbine tower barrel is used, first, the connecting parts at both ends of each group of steel wire ropes are fixed on the upper and lower flanges of the cylinder section. Then, the hanger assembly is sequentially installed in place from top to bottom through the connecting assembly.

[0025] Specifically, there are multiple sling assemblies 100, and the multiple sling assemblies 100 are evenly arranged in the barrel section. The sling assembly 100 includes a wire rope 110 and connecting parts 120 connected to both ends of the wire rope 110. The two connecting parts 120 can be respectively connected to the upper and lower flanges of the tower section. In specific implementation, generally 8 groups of sling assemblies 100 are used.

[0026] The hanger assembly 200 is used to install accessories. There are multiple hanger assemblies 200, and the multiple hanger assemblies 200 are sequentially arranged in the barrel section from top to bottom. The wire rope 110 sequentially passes through all the hanger assemblies 200. In this embodiment, the hanger assembly 200 includes multiple support rods, and the multiple support rods are cross-fixed to form the hanger assembly 200. In other implementation manners, a combination of a mounting plate and support rods can also be used.

[0027] Each wire rope 110 is connected to the corresponding hanger assembly 200 through a connecting assembly 300. Multiple adjusting support assemblies 400 are arranged on each hanger assembly 200, and the hanger assembly 200 is used for fixedly connecting with the inner wall of the barrel section.

[0028] During use, first fix the connecting parts 120 at both ends of each group of wire ropes 110 to the upper and lower flanges of the cylinder section. Then, install the hanger assembly 200 from top to bottom through the connecting assembly 300 in sequence. Subsequently, adjust the gap between the side wall of the hanger assembly 200 and the inner wall of the tower barrel to be uniform. Then, adjust the adjusting support assemblies 400 around the hanger so that the hanger assembly 200 is in firm contact with the inner wall of the tower barrel. Finally, use bolts to fix the internal accessories to the hanger assembly 200 from top to bottom in sequence to achieve the installation and fixation of the internal accessories.

[0029] By adopting such a fixing device for the internal accessories in the cylinder section, it will not excessively increase the weight of the tower barrel. At the same time, since welding is not required during fixation, it can avoid the situation where some internal accessories do not meet the requirements of high-grade welds. At the same time, it can also ensure the requirements for stable installation and fixation of all internal accessories.

[0030] In this embodiment, the connecting part 120 includes a thimble 121 and a shackle 122. A sling eye corresponding to the shackle 122 is provided on the flange, and the shackle 122 can be buckled with the sling eye.
