Description
Technical Field
The utility model belongs to the technical field of wind power generation, and particularly relates to a high tower escape system for inhibiting high tower vortex-induced vibration.
Background
In recent years, the wind power technology is rapidly developed, the wind turbine generator is enlarged more and more, and the tower barrel matched with the wind turbine generator is higher and higher. Nowadays, onshore wind power gradually advances to the middle, east and south low wind speed region, and a high tower and large blades become the mainstream solution for improving the power generation capacity in the region.
At present, the high tower technology mainly comprises a flexible tower, a mixed tower, a segment assembled tower, a guyed tower and the like, and the market mainly comprises the flexible tower and the mixed tower which are more technically mature.
The flexible tower can greatly reduce the weight of the tower drum, so the flexible tower is widely used; but also causes problems such as a low rigidity. As is well known, the "resonance" is a problem that is avoided as much as possible in all engineering, and the destructive and potential safety hazards caused by the resonance of the flexible tower are mainly avoided through solutions such as the "resonance crossing technology", the "unbalance compensation technology" and the "damping increase" in the industry at present. On the other hand, when the frequency of the shedding vortex formed by the wind blowing the tower is close to the tower frequency, the tower also resonates, and the phenomenon of interaction between the fluid and the structure is called vortex-induced vibration. On one hand, the hoisting difficulty is increased, and the construction efficiency is influenced; on the other hand, the service life of the unit is greatly consumed, and even the safety of operation and maintenance personnel is threatened.
In addition, the flexible tower has high height and large vibration amplitude, so that the escape of the engine room is difficult. At present, the escape means of the engine room adopts a speed-reducing rope mode to quickly reduce the escape personnel to the ground from the escape hole of the engine room. However, the descending speed of the fast descending rope is generally not more than 1m/s, and if the evacuee is on a flexible tower 140 m high, the evacuee needs at least more than three minutes from the connection and the activation of the fast descending device until the evacuee reaches the ground. After one person arrives at the ground and is disconnected from the quick-descent device, other people waiting for escape in the cabin can continue to use the device. When the escape is carried out in an emergency, the fast-falling rope has low escape efficiency and long escape time, and brings huge risks to escape personnel, especially people. In addition, when the escape personnel quickly fall, the flexible tower vibrates to have large amplitude of oscillation, so that the escape personnel can possibly collide with the tower barrel to cause potential damage to the escape personnel.
