Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example 1

Referring to fig. 1-3, an indoor self-excitation intelligent fire fighting device comprises a mounting box 1, a pressurizing bin 2, a linkage bin 8 and an alarm bin 14 are arranged in the mounting box 1, the linkage bin 8 is communicated with the outside through a release port 9, an insulating rotating rod 3 is rotatably mounted at the top of the linkage bin 8, a plurality of rows of balls are arranged between the insulating rotating rod 3 and a supporting structure so as to reduce the friction force applied when the insulating rotating rod 3 rotates as much as possible, a magnetic strip 4 is fixedly arranged in the insulating rotating rod 3, the magnetic strip 4 is close to the outer side of the insulating rotating rod 3, namely the magnetic strip 4 is not coaxial with the insulating rotating rod 3, one end of the insulating rotating rod 3 close to the pressurizing bin 2 is fixedly connected with a rotating plate 11 through a short shaft, a communication port 12 is arranged on the rotating plate 11 in a penetrating manner, an exhaust port 10 is arranged between the pressurizing bin 2 and the linkage bin 8, the rotating plate 11 is connected with the exhaust port, and the magnetic ring 5 is clamped with the inner wall of the linkage bin 8, the fire blanket 6 is arranged in the magnetic ring 5, and the alarm mechanism is arranged in the alarm bin 14.

In this embodiment, the alarm mechanism includes a controller 15 and a signal transmitter 16 fixedly installed in the alarm bin 14, the controller 15 is electrically connected to the signal transmitter 16, a coil 7 is wound in a side wall of the linkage bin 8, the coil 7 is electrically connected to the controller 15, and the controller 15 includes a voltage stabilizing module and a current stabilizing module therein, so that the working current of the signal transmitter 16 is kept stable.

In this embodiment, sodium bicarbonate powder is contained in the pressurizing chamber 2.

In this embodiment, the magnetic field direction of the magnetic stripe 4 is opposite to the magnetic field direction of the magnetic ring 5, the curie point of the magnetic stripe 4 is 260-320 ℃, and the curie point of the magnetic ring 5 is more than 380 ℃.

When the air compression box is used, the mounting box 1 is fixedly mounted on a ceiling, meanwhile, one side of the insulating rotating rod 3 with the magnetic strip 4 is arranged upwards, at the moment, the communication port 12 on the rotating plate 11 is staggered with the exhaust port 10, and the compression bin 2 is a closed space;

when a fire disaster occurs, the temperature in the mounting box 1 rises rapidly, the sodium bicarbonate powder in the pressurizing bin 2 is gradually decomposed into sodium carbonate, carbon dioxide and water, and the sodium bicarbonate can be completely decomposed when the temperature is higher than 270 ℃, and at the moment, because the rotating plate 11 seals the exhaust port 10, higher air pressure can be generated in the pressurizing bin 2;

under the high-temperature environment, the magnetism of the magnetic strip 4 is weakened, when the temperature is higher than the Curie point of the magnetic strip 4, the magnetic strip 4 can have obvious demagnetization, because in the initial state, one side of the insulating rotary rod 3 with the magnetic strip 4 is arranged upwards, the magnetic strip 4 and the magnetic ring 5 repel each other, the insulating rotary rod 3 is acted by upward force, so that the rotation cannot occur, but after the magnetic strip 4 is demagnetized, the insulating rotary rod 3 mainly bears the action of gravity, so that the side with the magnetic strip 4 can rotate downwards, the magnetic strip 4 rotates 180 degrees, at the moment, the rotary plate 11 rotates by a corresponding angle along with the rotation, the exhaust port 10 is opposite to the communication port 12, high-pressure gas in the pressurizing bin 2 is released instantly, and the magnetic ring 5 is pushed to drive the fire blanket 6 to slide downwards quickly;

because the Curie point of the magnetic ring 5 is higher, the environmental temperature at the initial stage of the fire cannot cause the magnetic ring 5 to be demagnetized, when the magnetic ring 5 slides downwards quickly, the magnetic field intensity between the coils 7 can also change, according to the Faraday electromagnetic induction principle, induced current can be generated in a closed loop formed by the coils 7, the controller 15, the signal transmitter 16 and other devices, so that the controller 15 and the signal transmitter 16 are opened, the controller 15 comprises a voltage stabilizing module and a current stabilizing module, the working current of the signal transmitter 16 is kept stable, the signal transmitter 16 is a wireless transmitter, a fire occurrence signal can be transmitted to a central control room, and people can find the fire in time;

when the magnetic ring 5 slides to the release opening 9, the magnetic ring 5 is blocked by the release opening 9 and cannot move continuously, at the moment, the fire blanket 6 can be separated from the magnetic ring 5 under the action of impact force and then downwards covered through the release opening 9 to control the spread of the fire below, the fire blanket 6 can be fixed with the magnetic ring 5 in a bonding mode, and the situation that the fire blanket 6 cannot be separated from the magnetic ring 5 is avoided.

Example 2

Referring to fig. 4, the present embodiment is different from embodiment 1 in that: a decorative plate 13 is arranged in the release port 9, the strength of the decorative plate 13 is low, and a fire extinguishing agent is filled above the decorative plate 13.

When this embodiment uses, when magnetic ring 5 drove fire blanket 6 and slided downwards, the space between decorative board 13 and the magnetic ring 5 was compressed, and pressure increases thereupon, and decorative board 13's intensity is less, can split under the pressure effect to release the fire extinguishing agent indoor, because the fire extinguishing agent can spread in the surrounding environment under the air current effect, so can increase the scope of putting out a fire, improve fire control effect, can avoid surrounding article to be lighted simultaneously.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
