Background
Wind power generation is a clean and sustainable energy form, and is greatly supported by the nation in recent years, so that the rapid development of domestic wind power is promoted.
The wind turbine mainly comprises a foundation, a tower frame, a main cabin, a hub and blades, wherein the tower frame accounts for more than 15% of the total cost of the wind turbine, and the tower frame is the most basic guarantee for the safety of the whole wind turbine. The safety of the tower must be improved and the cost of the tower must be reduced.
The tower of the wind driven generator is of a steel tubular structure, the tower comprises a plurality of tower barrels which are vertically installed and have the same central axis, tower barrel flanges 21 are arranged at two ends of each tower barrel, and fastening connection between the adjacent tower barrels is realized through a plurality of tower barrel connecting bolts 20 penetrating through the tower barrel flanges 21. A plurality of platforms are arranged inside the tower for the maintenance of the tower connecting bolts 20 and the temporary rest of the operation and maintenance personnel. The platform is parallel to the bottom of the tower and is typically mounted 1.2m below the tower flange 21 at the top of the tower. A certain gap is arranged between the platform and the inner wall of the tower. There will typically be a large distance between adjacent platforms, typically greater than 10 m. After the tower is erected, if the platform is damaged, no position is available below the platform where an operator can stand, and the tower connecting bolts can not be overhauled basically.
As shown in fig. 1, in the starting stage of the domestic wind power industry, the platform inside the tower designed by many domestic fan manufacturers is fastened and connected with the inner wall of the tower mainly through two connecting structures. One of the connecting structures includes a plurality of L-shaped structural platform supports and weld studs. The welding stud is welded on the inner wall of the tower cylinder below the platform and is perpendicular to the inner wall of the tower cylinder. The platform support is located below the platform and includes a first side of the platform support and a second side of the platform support that are perpendicular to each other. The second side of the platform support is parallel to the platform and is fixedly connected with the bottom of the platform through a platform connecting bolt 6. The platform support first side and the welding stud are fixedly connected through a welding stud fastener 5 penetrating through the first side of the platform. In another connection structure, as shown in fig. 2 and 3, an H-shaped support beam is fixedly connected between the bottom of the platform and the platform support, and the platform and the inner wall of the tower are fixedly connected through the support beam, the platform support and the welding stud.
As shown in fig. 8, a platform inside the wind turbine tower is provided with a ladder port 22, and a ladder penetrating through the ladder port 22 is arranged in the wind turbine tower. The worker stands on the ladder stand below the platform to check whether the weld stud fastener 5 falls off. When the fan runs, the tower can vibrate to a certain degree, particularly a two-layer platform at the top of the tower. By the comprehensive influence of the mounting quality of the platform and the vibration of the tower, when the tower reaches a certain age limit after being mounted, the welding stud fastener 5 can loosen and even fall off, so that the platform and the inner wall of the tower are not connected and fall off. After the welding stud fastener 5 loosens or falls off, the platform is no longer safe. Because the distance between adjacent platforms is far away, maintenance personnel can not maintain the tower connecting bolt through the structure in the tower. Aiming at the loosening or falling of the welding stud fastener 5, the prior technical scheme adopts a rope hanging mode to hang an operator below a platform for operation, so that the operation difficulty is very high, and potential safety hazards exist.
