Figure 1 is a front configuration diagram of a fire prevention system with a suffocation fire extinguishing function according to the present invention, Figure 2 is a side configuration diagram of a fire prevention system with a suffocation fire extinguishing function according to the present invention, and Figure 3 is a suffocation fire prevention system according to the present invention. This is a plan view of a fire protection system with a fire extinguishing function.

Referring to Figure 1, the fire prevention system having a suffocation fire extinguishing function of the present invention includes a frame 20, a first operating part 30, and a flame retardant cloth 40.

The frame 20 is installed on the outside of the server rack 10 to maintain a certain gap.

The frame 20 is closed on both sides by vertical plates 21, and an upper fixing plate 22 is fixed to the upper end to increase the rigidity of the frame 20.

The upper fixing plate 22 has a shape that protrudes outward from the vertical plate 21.

Guide rollers 53 of the second operating unit 50 are fixed inside both sides of the upper fixing plate 22, and the double-structured wheel 511 fixed to the shaft 51 is protected from being exposed to the outside.

Here, the server rack 10 is formed in a substantially rectangular parallelepiped shape, and a plurality of server modules M are mounted therein at regular height intervals.

The server rack 10 is formed so that both sides and the top are closed and the front and rear are open.

Also, referring to FIGS. 3 and 4, the first operation unit 30 is installed on the upper part of the frame 20 to lower the flame retardant cloth 40.

The first operating unit 30 includes a support member 31, a shaft 32, a drive motor 33, a drive chain 34, and a clutch 35.

The support member 31 is fixed to the inside of the vertical plate 21 of the frame 20 and is a structure for installing the shaft 32. The support member 31 is manufactured by bending a metal plate.

Among the support members 31, one support member 31 may be bent in multiple stages to secure the drive motor 33.

Among the support members 31, the other support member 31 is bent into a square shape and is fixed to the inside of the vertical plate 21 to support the end of the shaft 32.

One end of the shaft 32 is coupled to a support member 31 bent in multiple stages and rotated by a bearing, and the other end of the shaft 32 is coupled to a support member 31 bent into a square shape.

The drive motor 33 is fixed to the bent end of the support member 31 on one side, and the drive chain 34 is connected to a wheel formed on the axis of the drive motor 33 and a wheel formed on the shaft 32. The shaft 32 is rotated by driving the drive motor 33.

The drive motor 33 may rotate the shaft 32 to rewind the flame retardant cloth 40 that has fallen to the lower part of the frame 20 when a malfunction of the fire prevention system occurs or a large fire does not occur.

The clutch 35 is installed at one end of the shaft 32 to control the rotation of the shaft 32.

The clutch 35 is coupled to the end of the shaft 32 inside the support member 31 on one side and is fixed to the inside of the support member 31.

In normal times when fire or smoke is not detected, the clutch 35 is supplied with power and holds the shaft 32, thereby fixing the shaft 32 so that it does not rotate.

When fire or smoke is detected through the sensor unit, the control unit stops supplying power to the clutch 35, and the pressing force of the clutch 35 holding the shaft 32 is released, causing the shaft 32 to rotate.

The sensor unit is installed on the server rack 10 or frame 20 and may be a heat sensor or a smoke sensor.

The rotation of the shaft 32 can be controlled by a control unit, and when a power outage occurs due to a fire, the electricity supply to the clutch 35 is cut off, and the pressing force of the clutch 35 holding the shaft 32 is released, causing the shaft ( 32) may rotate.

Here, the clutch 35 may use an electronic clutch that controls the rotation of the shaft 32 using the magnetic force of an electromagnet. Since the clutch has the same structure as a conventional clutch, detailed description will be omitted.

Additionally, the flame retardant fabric 40 is wound around the shaft 32 of the first operation unit 30 to a certain length. Before fire or smoke is detected, the flame retardant cloth 40 is wound around the shaft 32 and the front and rear of the server rack 10 are opened. When fire or smoke is detected, the fire retardant cloth 40 is wrapped under its own weight. You can quickly respond to a fire by descending quickly.

Weight plates 41 having a certain weight are in close contact with the inside and outside of the lower end of the flame retardant cloth 40, respectively, and at least one rivet 42 is fastened to the weight plate 41 to attach the weight plate 41 to the fire retardant cloth. It is fixed at (40).

In addition, it may further include guide parts 80 formed before and after the frame 20.

The guide unit 80 includes a support body 81 and a guide rail 82.

The support body 81 is formed vertically on both front and rear sides of the frame 20 to reinforce the rigidity of the frame 20.

The guide rail 82 is fixed in a bent shape to the inner direction of each support body 81 and guides the raising and lowering of the flame retardant fabric 40.

The guide rail 82 accommodates both ends of the flame retardant cloth 40 to suffocate the server rack 20 as much as possible.

Referring to FIG. 5, when the flame retardant cloth 40 descends along the guide rail 82, the weight plate 41 at the bottom of the fire retardant cloth 40 absorbs the impact generated when it hits the lower part of the frame 20. It may further include a shock absorbing part 90 that absorbs shock.

The shock absorbing part 90 includes an external case 91, a first cushioning member 92, a diaphragm 93, an elastic member 94, and a second cushioning member 95.

The outer case 91 is coupled to the lower part of the frame 20, and a hook is formed at the lower end to prevent separation from the frame 20 while moving up and down.

The first buffer member 92 is coupled to the upper inner side of the outer case 91, and the upper end protrudes upward from the outer case 91 to primarily cushion the impact when the flame retardant cloth 40 is lowered.

The diaphragm 93 is made of metal or resin and separates the elastic member 94 and the buffer member 95.

The elastic member 94 is made of an elastic material and secondarily cushions the impact when the flame retardant cloth 40 is lowered.

The second buffer member 95 is made of a sponge material that can effectively absorb shock, and is mounted between the elastic members 94.

In addition, when the flame retardant cloth 40 is completely lowered to the lower part of the frame 20, when the repulsive force of the shock absorber 90 occurs, the weight plate 41 at the bottom of the fire retardant cloth 40 bounces upward. It may further include a lifting prevention unit to prevent lifting.

The lifting prevention part is formed with a support rib 96 formed on the outside of the guide rail 82, and a lifting prevention member 97 is mounted on the support rib 96 so as to rotate about an axis.

A spring 98 is mounted on the axis to restore the initial state after the rotation of the anti-elevation member 97, so that after the fire-resistant cloth 40 is lowered, the upper part of the weight plate 41 is supported to support the flame-resistant cloth 40. This prevents the phenomenon from bouncing upward.

In addition, referring to FIGS. 6 and 7, when the flame retardant fabric 40 descends to the lower part of the frame 20 along the guide rail 82, the flame retardant fabric 40 located inside the guide rail 82 It may further include a wrinkle-prevention portion 100 that allows both ends to unfold tautly without being wrinkled.

The wrinkle prevention part 100 includes a striking rib 101, a support frame 102, a wrinkle prevention member 103, and an operating space 104.

The striking ribs 101 protrude on both sides of the upper end of the weight plate 41 fixed to the lower end of the flame retardant cloth 40, and are formed to slope inward from the top to the bottom.

The support frame 102 is each fixed to the outside of the guide rail 82, and the inner and outer directions of the guide rail 82 have an open shape.

The wrinkle-prevention member 103 is rotatably fixed to the inside of the support frame 102 through an axis, and is rotated by the impact of the striking rib 101 when the flame retardant fabric 40 is lowered.

The wrinkle prevention member 103 includes a striking plate 103a and a wrinkle prevention guide 103b.

The striking plate 103a is located below the striking rib 101, and the wrinkle prevention guide 103b is formed at a certain angle from the striking plate 103a and is located inside the support frame 102.

The striking plate (103a) and the wrinkle prevention guide (103b) form an obtuse angle.

The operating space 104 is formed through the guide rail 82 and is a space in which the anti-wrinkle member 103 rotates.

In addition, a support piece 105 is formed inside the support frame 102 to support the wrinkle prevention guide 103b of the wrinkle prevention member 103 and prevent the wrinkle prevention guide 103 from rotating during normal times.

An elastic piece 106 is formed on the inner lower part of the support frame 102 to allow the striking plate 103a to rotate elastically when the anti-wrinkle member 103 rotates due to the descent of the fireproof fabric 40.

A stopper 107 is formed at the lower part of the support piece 105 on one side of the elastic piece 106, and after the anti-wrinkle member 103 rotates due to the lowering of the flame retardant fabric 40, the striking plate 103a is no longer used. It is supported so that it does not rotate.

As described above, when the anti-wrinkle member 103 rotates due to the lowering of the flame retardant cloth 40, the anti-wrinkle guides 103b are positioned close to or in close contact with both sides of the flame retardant cloth 40, so that the flame retardant cloth 40 is taut. It unfolds.

For example, in the absence of the anti-wrinkle member 103, when the flame retardant fabric 40 is lowered, the repulsion force due to floor impact or if it is not lowered while being properly guided by the guide rail 82 may cause wrinkles in the flame retardant fabric 40. As a result, the suffocation condition of the server rack 10 becomes poor, and the wrinkle prevention unit 100, which is a product of the present invention, can prevent this phenomenon.

In other words, when fire or smoke is detected, the fire prevention system with the suffocation fire extinguishing function of the present invention detects the fire through a sensor unit that detects temperature or smoke installed on the frame 20 or in a position close to the frame 20, When a fire is detected, the control unit controls the first operation unit 30.

First, the power supplied to the clutch 35 of the first operation unit 30 is stopped. When the power supply is stopped, the pressing force of the clutch 35 holding the shaft 32 is released.

The flame retardant cloth 40 wound around the shaft 32 is rapidly lowered to the lower part of the frame 20 as the shaft 32 rotates due to the load of the weight plate 41 fixed to the lower end. I do it.

At this time, both ends of the flame retardant cloth 40 are guided along the guide rail 82 of the guide part 80 and stably descend.

When the flame retardant cloth 40 is lowered to the lower part of the frame 20 as described above, the front and rear of the server rack 10 are closed and the server rack 10 is put into a suffocation state, so the fire is quickly extinguished and further. This will prevent further spread of fire.

In other words, if a fire occurs in the server rack 10, the front and rear of the server rack 10 are closed to create a suffocation state, thereby effectively preventing the fire and the spread of the fire.
