Wind Turbine Automatic Fire Control System

Abstract

An automatic fire control system for a wind power generating set, characterized in that it includes an aspirating smoke-sensing fire detection and alarm device, a fire monitoring device, an automatic fire extinguishing device and a special fire-proof blocking device; the aspirating smoke-sensing fire detection and alarm The device includes an aspirating smoke detector and a supporting sampling pipeline; the fire monitoring device is installed in the central control center of the wind farm, and the automatic fire extinguishing device includes a pulse type dry powder automatic fire extinguishing device and an aerosol automatic fire extinguishing device , used to realize full submersion fire extinguishing protection; the special fire-proof sealing device is installed at the connection between the wind turbine cabin and the tower, and the air-breathing smoke-sensing fire detection and alarm device of the present invention samples in real time, self-analyzes, and makes self-decision alarms Level, it is convenient for the staff to grasp the progress of the fire situation in real time, and implement fire protection measures correctly and reliably according to the alarm level. The perfect information self-providing and self-analysis capabilities facilitate the correct and orderly execution of fire management work.

Description

technical field [0001] The invention relates to a fire-fighting system, in particular to an automatic fire-fighting control system for a wind power generating set in the wind power field. Background technique [0002] As a clean and renewable new energy, wind energy has been paid more and more attention by countries all over the world. At present, with the rapid development of wind power generation technology, safety accidents continue to occur, among which fire accidents account for a large proportion, and fire accidents have caused huge economic losses to the wind power industry. [0003] Wind turbines are generally installed in relatively remote places, far away from fire rescue centers, and some wind turbines are even installed at sea, which makes it difficult to supply fire supplies in time, causing certain difficulties in fire rescue. In addition, the height of wind turbines is generally 70-100 meters, and when a fire accident occurs, the temperature of the ignition p...

Problems solved by technology

[0005] In order to overcome the problems caused by wind turbine fires, Chinese patent application No. 2009100352014 discloses a wind turbine cabin fire automatic measurement and control and emergency system. Difficulties need to be solved urgently, reflected in: First, there is no reasonable fire alarm level and fire mode under each fire alarm level, and the corresponding fire mode cannot be executed immediately according to the fire parameter value

Second, the firefighting system only uses an inert gas fire extinguishing system, and does not use corresponding fire extinguishing substances for different components of the wind turbine. At the same time, the inert gas can easily suffocate people and cause other physiological hazards

Third, the detectors used are temperature sensors, smoke sensors and oxygen concentration sensors, so the sensitivity is not high enough

Fourth, it is impossible to accurately find the source of the fire during the remote monitoring of the fire and carry out targeted fire fighting according to the severity of the fire in different parts of the wind turbine cabin, and there is no mention of controlling the jet flow rate of the fire extinguishing material
