Description

Fire detection and fire extinguishing system

FIELD OF THE INVENTION The present invention relates to a fire detection and fire extinguishing system, and more particularly, to a fire detection and fire extinguishing system capable of sensing fire occurrence, preventing suffocation by smoke, and extinguishing a fire.

Due to the proliferation of residential spaces, buildings such as high-rise apartments have emerged, and fire has become a serious problem in such high-rise buildings.

The apartment sprinkler system is installed on the ceiling of the building. When a fire occurs, the valve that was closed by the temperature sensor installed on the sprinkler head is opened automatically, Fire fighting equipment.

However, it is a reality that the smoke generated in the apartment fire is already suffocated by the person before the fire is suppressed by the sprinkler, and the suffocating smoke is generated by the toxic smoke.

In other words, before the initial fire suppression equipment such as a sprinkler is operated, it is necessary to secure time to prevent a person from suffocating by toxic gas such as toxic smoke. Until now, And it is insufficient to exhaust the toxic gas at the first golden time corresponding to the time of the human life.

In other words, it is not effective to prevent asphyxia due to toxic gas because it is alarmed by detection function in case of fire. There is a fire suppression function by a sprinkler system by fire but there is no disaster prevention function against smoke, so there was a big problem that it is not enough to prevent a person from suffocating by a toxic gas in a fire.

That is, when the controller 610 receives the fire detection signal of the fire detector 200 and the fire signal through the temperature sensor 620, the measuring unit 600 detects the fire signal of the sprinkler 500, As shown in FIG.

The compartment means 700 is mounted on the top of the ceiling 10 in close proximity to the veranda or window.

That is, the partitioning unit 700 divides the inside space while extinguishing the nearby part when a fire occurs.

The partitioning means 700 is wound around the inlet 710 disposed at the upper portion of the ceiling 10 and moved downward through the communication hole 12 formed in the ceiling 10, A weight 730 mounted on the end of the barrier 720 and spaced from the end of the barrier 720 to move the barrier 720 to the ground, And a lifting motor 740.

That is, in the partitioning means 700, when a fire occurs, a known pin for fixing the collet 710 is removed by the operation of a solenoid or a cylinder, and the blocking film 720 is moved in the movement of the weight 730 So as to partition the fire zone and the escape space.

At this time, a fire extinguishing pipe 750 may further be installed on the front or rear of the communication hole 12 of the ceiling 10 so as to inject water supplied through a water supply pipe in a downward direction.

That is, the partitioning unit 700 evolves the fire while cooling the blocking film 720 through the water supplied through the fire extinguishing pipe 750.

Then, the lifting motor 740 rotates the take-up reel 710 after the fire extinguishes, thereby returning the barrier 720 and the weight 730 to their original positions.

Hereinafter, a fire detection and fire extinguishing system constructed as above will be described with reference to FIGS.

The main discharge pipe 320 is connected to the upper portion of the ceiling 10 and is connected to the outside while one end of the main discharge pipe 320 is connected to the main discharge pipe 320 and the other end is connected to the ceiling 10 And an exhaust means 300 constituted by an auxiliary exhaust pipe 340 having an on-off valve 342, respectively.

The fire detector 200 and the sprinkler 500 are mounted on the ceiling 10 at intervals.

Next, a case 410 in which a receiving space 412 is formed in the lower portion of the auxiliary discharge pipe 340 constituting the discharging means 300 and a gas inflow hole 414 is formed in the lower portion, And a suction fan 430 mounted on the rotating shaft of the driving motor 420 and sucking the gas by using the gas inflow hole 414. The driving motor 420 is installed in the receiving space 412 of the driving motor 420, Respectively.

A controller 610 for receiving an induction gas generation signal of the fire sensor 200 to one side of the suction unit 400 and transmitting an operation signal to the driving motor 420 and the sprinkler 500, And a temperature sensing sensor 620 for transmitting the operation signal of the driving motor 420 and the sprinkler 500 to the controller 610 at the time of sensing abnormality.

Next, a grating 710 disposed on the ceiling 10 at an upper portion of the ceiling 10 in proximity to a veranda or a window, a communication hole 12 wound on the grating 710 and formed in the ceiling 10, A weight 730 mounted on the end of the blocking film 720 at an interval to move the blocking film 720 to the ground, 710, the installation of the fire detection and fire extinguishing system 100 is completed when the partitioning means 700 including the lifting motor 740 mounted on the side of the fire detection and fire system 710 is installed.

Here, the order of installation of the fire detection and fire extinguishing system can be configured differently from the above.

Next, the use of the fire detection and fire extinguishing system will be described.

First, when the controller 610 receives a fire detection signal from the fire detector 200 and a fire signal through the temperature sensor 620, the controller 610 controls the drive motor 420 and the sprinkler 500 And transmits an operation signal.

The sprinkler 500 supplies digestion liquid to the inside of the room to extinguish the fire and the driving motor 420 of the suction unit 400 operates to rotate the suction fan 430 to rotate the gas inlet hole 414, So that the gas in the room is sucked.

At this time, the open / close valve 342 constituting the discharge means 300 is opened, and the gas flowing through the auxiliary discharge pipe 340 is discharged to the outside by the main discharge pipe 320 and the blowing fan 322.

In addition, the partitioning means 700 removes a known pin for fixing the gate 710 after receiving an operation signal through the controller 610 in the event of a fire, and the blocking film 720 is disposed at a lower portion And moves in the downward direction according to the movement of the weight 730, thereby separating the fire zone and the escape space.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It should be construed as being included in the scope of the right.
