Problems solved by technology

Due to the need for cooling and heat dissipation of the internal components of the wind turbine, the casing of the nacelle is designed with vents, resulting in a semi-closed state of the nacelle. Externally, the fire extinguishing agent will be lost from the vent soon, which will have a great adverse effect on the fire extinguishing effect

Embodiment Construction

[0014] Such as figure 1 As shown, a shutter control system of a wind power generating set includes a shutter controller 1, a shutter driving device 2, and a shutter 3; the shutter driving device 2 adopts an electric push rod and is connected to the shutter 3 installed at the air vent of the engine room; The louver controller 1 is connected to the louver driving device 2; the louver controller 1 is connected to the alarm signal of the fan automatic fire extinguishing system, and at the same time is connected to the temperature sensor signal in the engine room. The entire shutter control system is arranged inside the engine room.

[0015] The working process of the present invention is: when the automatic fire extinguishing system confirms that a fire has occurred, the automatic fire extinguishing system sends out a fire alarm signal, and the shutter control system starts immediately after receiving the fire signal, and controls the shutters at the vents of the engine room to cl...

Abstract

The invention discloses a louver control system of a wind power generation unit. The system is characterized by comprising a louver controller, a louver driving device and a louver, wherein the louver driving device is connected with the louver which is arranged at a ventilation opening of a cabin, the louver controller is connected with the louver driving device, and the louver controller is connected with an alarming signal of an automatic fire extinguishing system of a fan, and is also connected with a signal of a temperature sensor in the cabin. The system has the advantages that after a fire is determined by the automatic fire extinguishing system, the louver control system can timely control the closing of the louver at the ventilation opening of the cabin, and a sealed environment is formed in the cabin, so the fire is favorably extinguished; on the premise of no fire and normal running of the power generation unit, the louver control system can control the opening or closing of the louver at the ventilation opening of the cabin at certain temperature value according to the temperature which is obtained by the temperature sensor in the cabin, so the temperature is automatically adjusted.

Description

technical field [0001] The invention relates to the field of fire protection of wind power equipment, in particular to a shutter control system of an automatic fire extinguishing system of a wind power generating set. Background technique [0002] The horizontal axis wind turbine is a very special power generation system, and its internal components are highly concentrated, especially the nacelle, which is equipped with gearboxes, generators, main control cabinets and brakes. In order to effectively capture stable wind energy to the greatest extent, the nacelles and hubs of large wind turbines are installed tens of meters above the ground. Once a fire breaks out in the wind turbine cabin, due to the height and location of the wind turbine installation, firefighters cannot extinguish it, and can only let it burn until it is automatically extinguished, causing very serious losses. Therefore, the automatic fire extinguishing system of wind power generators has been paid more a...
