Automatic source-free superfine-dry-powder extinguishing method and device for engine room of wind generating set

Abstract

The invention relates to an automatic source-free superfine-dry-powder extinguishing method and device for the engine room of a wind generating set, and belongs to the technical field of wind generating set firefighting. The invention adopts the technical scheme as follows: a temperature-sensing magnetic generator (4) is connected to the ignition controller (6) of the extinguishing device body (1) through a cable (5); the starting head of the temperature-sensing magnetic generator and the nozzle of the extinguishing device face to the body of a generator (8); when the temperature around the generator reaches a set fire temperature, the starting head of the temperature-sensing magnetic generator starts the ignition controller, after the ignition controller works, high pressure is instantly generated in the body of the extinguishing device, and superfine dry powder rushes at the blasting diaphragm of the nozzle, and sprays to the body of the generator, so that a fire is put out. The automatic source-free superfine-dry-powder extinguishing device is low in cost, high in speed and environmentally friendly, and the fire does not reburn; the extinguishing device is close to an object to be protected and can put out the fire in the bud, the loss caused by fire can be reduced effectively, and production recovery is facilitated; field staffs are not injured by the extinguishing device during the use of extinguishing device, and the extinguishing device is very suitable for an unmanned station or a department required to be protected importantly.

Description

technical field [0001] The patent of the present invention relates to a passive ultrafine dry powder automatic fire extinguishing method and device for a wind power generating set nacelle, and belongs to the technical field of wind power generating set fire protection. Background technique [0002] At present, the common fire extinguishing devices in the nacelle of wind turbines all use a manual CO 2 Fire extinguishers cannot realize automatic fire extinguishing. Once a fire occurs, fire rescue cannot be achieved at all; and most of the wind turbines are installed at high altitudes far away from urban areas. The fire is easy to spread, causing fire accidents and causing heavy losses. How to deal with the fire in the wind turbine cabin It has become a technical problem to be solved urgently in this field. The fire extinguishing device of the background technology cannot be activated once the power is cut off. The container bottle of the traditional fire extinguishing device ...

[0002] At present, the common fire extinguishing devices in the nacelle of wind turbines all use a manual CO 2 Fire extinguishers cannot realize automatic fire extinguishing. Once a fire occurs, fire rescue cannot be achieved at all; and most of the wind turbines are installed at high altitudes far away from urban areas. The fire is easy to spread, causing fire accidents and causing heavy losses. How to deal with the fire in the wind turbine cabin Has become a technical problem to be solved urgently in this field

The fire extinguishing device of the background technology cannot be activated once the power is cut off. The container bottle of the traditional fire extinguishing device is easy to leak the fire extinguishing agent. The traditional fire extinguishing agent has poor low temperature resistance and is not suitable for use in a low temperature environment. It is also large in size, low in efficiency and high in cost.
