Description
Affiliated technical field:
The utility model relates to a kind of cabin automatic fire extinguisher, is used for the wind generating set engine room self-extinguishing, can put out automatically quickly and effectively in the cabin because the fire that electric fault causes.
Background technology:
There are a large amount of consumers and power cable in wind generating set engine room inside, breaking out of fire dangerous higher.Because most times of wind-powered electricity generation unit are in the unmanned state, and the cabin is in the height more than 70 meters, and common fire-fighting equipment is difficult to prove effective, so fire often causes expensive generating equipment to be destroyed overnight.
The utility model content:
The utility model purpose provides a kind of cabin automatic fire extinguisher, adopts the automatic ejecting extinguishing of pure nitrogen gas, automatically, in time puts out the fire in the wind-powered electricity generation machine cabin, avoids the heavy losses of property, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
The cabin automatic fire extinguisher comprises the gas storage steel cylinder, connects flexible pipe, check valve, selector valve, actuating mechanism, nozzle, temperature sensor, Smoke Sensor, main control PLC, the gas storage steel cylinder is connected with nozzle by connection flexible pipe, check valve, selector valve, actuating mechanism is connected with the control end of selector valve, the selector valve controlling organization is connected with main control PLC, and temperature sensor, Smoke Sensor are connected with main control PLC.
Said actuating mechanism is formed by starting gas cylinder and magnetic valve, starts gas cylinder and is connected with the control end of selector valve by magnetic valve, and the control end of magnetic valve is connected with main control PLC.
Said gas storage steel cylinder quantity is arbitrarily, and the gas storage steel cylinder is provided with valve body, and a plurality of gas storage steel cylinders are arranged in parallel, and each gas storage steel cylinder all passes through valve body, connects flexible pipe, check valve is connected with header, and header is connected with nozzle by selector valve.
Main control PLC is a programmable controller.
Adopt the utility model, a whole set of extinguishing device is positioned at the below, cabin, be installed on one deck platform of tower tube the top, calculate the required nitrogen quality of nitrogen fire smothering according to the cabin volumeter, nitrogen is stored in one group of steel cylinder, valve body on the steel cylinder connects check valve through connecting flexible pipe, connects header again.Header connects the nozzle be distributed in below the cabin by selector valve, and selector valve is opened by starting drive.Valve body is the quick open valve that is configured on the nitrogen steel cylinder, is used to fill and dispensing nitrogen extinguishing agent fast.The startup of fire monitoring and automatic fire extinguisher is by the main control PLC control of wind-powered electricity generation unit, when PLC has monitored the fire generation by smoke detector and hygrosensor, PLC sends instruction and drives the magnetic valve that starts on the gas cylinder, the gas that drives gas cylinder is opened selector valve earlier by driving pipeline, nitrogen cylinder body valve the external gas pressure rises rapidly, when pressure during greater than the valve body spring pressure valve body open, discharge the extinguishing chemical in the gas bomb.The extinguishing chemical that comes together in the header flows to nozzle by selector valve from take over, by the nozzle ejection, implement fire extinguishing.
The beneficial effects of the utility model are: when having fire to take place in the cabin, extinguishing device can start automatically, in the cabin, spray high-purity nitrogen from bottom to top, because the convection action that the cabin fire forms, nitrogen rises rapidly and is filled in the cabin, the volume fraction of oxygen in the cabin is reduced to below 15% fast, burning is extinguished very soon.Because density of nitrogen and air are approaching, nitrogen gas concn can keep considerable time in the cabin, prevents the fire resume combustion.The utility model adopts the automatic ejecting extinguishing of pure nitrogen gas, and fire-fighting mode is the physics fire extinguishing.Nitrogen belongs to inert gas, can not produce the pharmacology injury to the person, can put out the electrical fire that takes place in the cabin fast, the no secondary disaster in fire extinguishing back.Have noresidue after economic, practical, quick extinguishing, the fire extinguishing, electrical system and environment are not had characteristics such as influence.
Description of drawings:
Accompanying drawing is the utility model example structure schematic diagram;
Among the figure: 1. gas storage steel cylinder, 2. valve body 3. connects flexible pipe, 4. check valve, 5. header, 6. connector, 7. selector valve 8. starts gas cylinder, 9. magnetic valve, 10. nozzle, 11. temperature sensors, 12. Smoke Sensors, 13. main control PLC.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, the cabin automatic fire extinguisher comprises gas storage steel cylinder 1, connects flexible pipe 3, check valve 4, selector valve 7, actuating mechanism, nozzle 10, temperature sensor 11, Smoke Sensor 12, main control PLC 13, the gas storage steel cylinder is connected with nozzle by connection flexible pipe, check valve, selector valve, actuating mechanism is connected with the control end of selector valve, the selector valve controlling organization is connected with main control PLC, and temperature sensor, Smoke Sensor are connected with main control PLC.Actuating mechanism is formed by starting gas cylinder 8 and magnetic valve 9, starts gas cylinder and is connected by the control end of magnetic valve with selector valve 7, and the control end of magnetic valve 9 is connected with main control PLC 13.Gas storage steel cylinder 1 is provided with valve body 2, and a plurality of gas storage steel cylinders are arranged in parallel, and each gas storage steel cylinder all passes through valve body, connects flexible pipe, check valve, connector 6 are connected with header 5, and header is connected with nozzle by selector valve.
