Description

Technical Field

[0001] The invention relates to a fire fighting method, and is particularly applicable to fire fighting work. Background Art

[0002] In high-rise buildings, once a fire occurs, the existing fire-fighting equipment is difficult to be effective for high floors; fire-fighting methods that mainly use water will destroy everything to varying degrees wherever the water goes, and it is difficult for water to reach the fire point at high places or in mezzanine spaces, so the fire-fighting effect is not ideal. Summary of the invention

[0003] The present invention intelligently and reasonably utilizes carbon dioxide gas to isolate oxygen in a certain sealed or semi-sealed space, and intelligently eliminates fire hazards in the bud. Even if a big fire occurs, the carbon dioxide gas can be used to open the high-temperature resistant airbag, quickly block the oxygen channel, and quickly inject carbon dioxide gas into the fire scene to extinguish the fire. No matter how high the floor is or what kind of burning objects are on fire, the fire can be accurately and quickly eliminated, and the fire scene can be protected to the maximum extent, reducing damage to objects.

[0004] The technical solution adopted by the present invention is as follows: the intelligent fire protection mainly comprises: a carbon dioxide gas cylinder (1), an air pipe (2), a gas leakage alarm (3), an electromagnetic valve gas valve switch (4), a high temperature resistant air bag (5), a smoke alarm (6), and a thermistor temperature control switch (7); the carbon dioxide gas cylinder (1) is connected to each floor of a building by an air pipe (2); the electromagnetic valve gas valve switch (4) and the gas leakage alarm (3) are installed at each gas outlet of the air pipe (2); the smoke alarm (6) and the thermistor temperature control switch (7) are installed on the ceiling of the building or above the flammable material; the high temperature resistant air bag (5) is installed beside the door and window of the building, and the air pipe (2) is connected to the high temperature resistant air bag (5).

[0005] The air leakage alarm (3) is mainly composed of an air pipe (2), a float (8), a float handle (9), a water pipe (10), a water plug (11), a shaft (12), a cylinder body (13), and an electric switch (14); the float (8) is connected to the float handle (9), the water plug (11) is plugged in the water outlet of the water pipe (10), the shaft (12) passes through the float handle (9), and the shaft (12) is fixed on the water pipe (10) next to the water plug (11), and the electric switch (14) is arranged in the cylinder body (13) next to the end of the float handle (9).

DETAILED DESCRIPTION

[0010] Figure 2 , Figure 3 As shown, the carbon dioxide gas cylinder (1) is filled with high-pressure carbon dioxide gas, and the electromagnetic valve gas switch (4) is closed. When the carbon dioxide gas leaks into the air pipe (2), the carbon dioxide gas squeezes out almost all the water in the cylinder body (13) from the other air pipe (2), and the carbon dioxide gas can be discharged from the air outlet of the air pipe (2). Under the action of its own gravity, the float (8) in the cylinder body (13) sinks with the water level. The float (8) uses the shaft (12) as a fulcrum to swing the float handle (9). The end of the float handle (9) presses the electric switch (14), and the electric switch (14) turns on the sound box to emit a voice alarm of carbon dioxide gas entering the room, reminding the people in the house to leave and wait for the maintenance personnel to check and repair. When the cylinder (13) lacks water, the float (8) sinks with the water level, the float (8) swings the float handle (9) with the shaft (12) as the fulcrum, the float handle (9) presses the water plug (11) into the water pipe (10), a gap is formed between the water plug (11) and the water outlet of the water pipe (10), the tap water flows into the cylinder (13) from the water outlet of the water pipe (10), the water level in the cylinder (13) returns to the original high level, the water lifts the float (8), the float (8) swings the float handle (9) with the shaft (12) as the fulcrum, the float handle (9) leaves the water plug (11), and the water plug (11) plugs the water outlet of the water pipe (10) again under the action of the water pressure. In this way, the water volume in the cylinder (13) is always stable, and the electromagnetic valve air valve switch (4) will automatically alarm once it leaks.

[0011] Figure 1 , Figure 2 , Figure 3As shown, the carbon dioxide gas cylinder (1) is filled with high-pressure carbon dioxide gas. When a fire occurs in a house, smoke and dust in the house increase, the temperature rises, and the smoke and dust alarm (6) and thermistor temperature control switch (7) in the house sense and turn on the power to alarm. After the power is turned on, the smoke and dust alarm (6) and thermistor temperature control switch (7) open the electromagnetic valve gas valve switch (4) of the carbon dioxide gas cylinder (1) and the electromagnetic valve gas valve switch (4) of the house on fire, and the high-pressure carbon dioxide gas is introduced from the carbon dioxide gas cylinder (1) through the air pipe (2) into the house on fire to extinguish the flames. At the same time, the water in the gas leakage alarm (3) is squeezed out of the air pipe (2) by the high-pressure carbon dioxide gas, and the gas leakage alarm (3) emits an alarm voice indicating that carbon dioxide gas has entered the house. When the people in the house hear the alarm voice, they quickly go outside the house on fire. When the flames develop into a big fire, the carbon dioxide gas fills the high temperature resistant airbag (5) within a certain period of time according to the setting requirements. The high temperature resistant airbag (5) expands, blocks the doors and windows, and cuts off the oxygen from the outside from entering the house on fire. At the same time, the high pressure carbon dioxide gas in the carbon dioxide gas cylinder (1) is continuously introduced into the house on fire, squeezing the oxygen in the house on fire out of the house, and the fire will be extinguished due to lack of oxygen indoors.

[0012] When the electromagnetic valve gas valve switch (4) fails to function and leaks, the high-pressure carbon dioxide gas leaks into the house through the gas pipe (2), and the gas leakage alarm (3) will emit an alarm voice indicating that carbon dioxide has entered the house. When the people in the house hear the alarm sound, they will leave the house in time to avoid a large amount of carbon dioxide gas entering the house and causing breathing difficulties. After the repair is completed, they can move into the house normally.
