Description

A partitioned automatic fire protection system for wind power generators

technical field

The utility model relates to a fire-fighting system, in particular to a partition type automatic fire-fighting system for wind power generators.

Background technique

Since most wind turbines operate in remote areas, they are basically unattended or remotely monitored, and the internal structure of the wind turbine is complex, which poses a great fire hazard. The traditional fire extinguishing method generally adopts the total flooding scheme of carbon dioxide gas, which requires a small area to be protected and a completely enclosed space. However, the development trend of wind turbines is high power, and the volume of wind turbines is getting larger and larger. The structure of wind turbines determines that they cannot be completely sealed. The connection between the hub and the nacelle adopts a brush structure, which mainly blocks large particles of wind and sand from entering the wind turbine. The engine room; because the fan needs to constantly face the wind direction, the engine room itself must be rotated, and the junction of the engine room cover and the tower is also made of a brush structure; It cannot be effectively sealed with the tower. These structures determine that the fan is a space that cannot be completely sealed, and the gas fire extinguishing method is not ideal due to the leakage of the fire extinguishing gas, and there is a risk of fire resurgence. At the same time, in the bottom area of the fan tower, there is a transformer with high fire risk. Since the transformer is exposed inside the fan tower, it is impossible to use the gas fire extinguishing method, which requires a large amount of gas. In addition, considering that there are frequent maintenance personnel in the wind turbine, the full flooding gas fire extinguishing method is adopted. Once it erupts, it will be a fatal threat to the life of the maintenance personnel inside the wind turbine.
