Description

Technical Field

[0001] The utility model relates to the technical field of physical environment construction of a computer room, in particular to a passive gas discharge channel device for gas fire protection in a computer room. Background Art

[0002] In critical facilities such as computer rooms, gas firefighting systems are widely used due to their high fire extinguishing efficiency and residue-free nature. Heptafluoropropane, a commonly used fire extinguishing agent, quickly fills the computer room and effectively extinguishes the fire. However, after extinguishing the fire, the high concentration of heptafluoropropane gas remaining in the computer room poses a potential threat to personnel entering the room for subsequent operations. Traditional methods typically reduce the gas concentration in the computer room through natural or forced ventilation, but this method is time-consuming and its effectiveness is significantly affected by the room's structure and environmental conditions.

[0021] See also Figure 1-5 The utility model provides a technical solution: a passive air release channel device for gas fire protection in a machine room, comprising: a channel body 1, a partition 4 is fixedly installed on the inner wall of the channel body 1, a circular hole 5 is opened on the surface of the partition 4, an air pressure sensitive valve 6 is fixedly installed on one side of the partition 4, an outdoor plate 8 is provided at one end of the channel body 1, a groove 801 is opened on one side of the outdoor plate 8, electric telescopic rods 12 are fixedly installed at the four corners of the inner wall of the groove 801, a sealing plate 13 is fixedly installed on the other end of the electric telescopic rod 12, a lifting groove 14 is opened on one side of the sealing plate 13, and a notice board assembly 16 is provided on the inner wall of the lifting groove 14.

[0022] Specifically: When the device starts to be used, the channel body 1 is made of lightweight, corrosion-resistant material with sufficient strength and sealing to ensure that it can automatically open and close to pass gas under the action of the pressure difference inside and outside the machine room. After the fire in the machine room is extinguished, the pressure sensitive valve 6 is the AR2000 series of AirTac, and the pressure difference inside and outside the machine room is detected through the pressure sensitive valve 6. When the outdoor air pressure is higher than the air pressure in the machine room, the data is transmitted to the controller through the pressure sensitive valve 6, and the controller controls the start to open the circular hole 5 to allow gas to enter. At the same time, the data is transmitted to the controller, and the controller starts the electric telescopic rod 12 to extend the sealing plate 13 from the inner wall of the groove 801 to discharge the air pressure inside the machine room, so that the device no longer needs an external power source, and automatically opens using the pressure difference inside and outside the machine room to achieve rapid deflation, making the device more perfect.

[0023] In one embodiment, a mounting plate 2 is fixedly mounted on the other end of the channel body 1 , and a louver 3 is fixedly mounted on the inner wall of the other end of the channel body 1 .

[0024] Specifically: embed the channel body 1 into the wall, attach it to the wall through the mounting plate 2, and fix it with screws, so that the device is stably installed on the wall, making the device more perfect.

[0025] In one embodiment, a mounting block 9 is fixedly installed on the other side of the outdoor panel 8, and the surface of the mounting block 9 is embedded in the inner wall of one end of the channel body 1. A threaded groove 7 is opened at one end of the channel body 1, and the number of the threaded grooves 7 is four. A threaded hole 10 is opened on the inner wall of the groove 801, and the number of the threaded holes 10 is four. The inner wall of the threaded hole 10 is threadedly embedded with a bolt 11, and the surface of the bolt 11 is threadedly embedded in the inner wall of the threaded groove 7.

[0026] Specifically: by embedding the mounting block 9 fixed on the other side of the outdoor panel 8 into the inner wall of one end of the channel body 1, each threaded hole 10 is aligned with its corresponding threaded groove 7, and by tightening the bolt 11, the outdoor panel 8 is fixed to one end of the channel body 1, making the device more perfect.

[0027] In one embodiment, the notice board assembly 16 includes a warning plate 1601, sliders 1602 are fixedly installed on both sides of the warning plate 1601, slide grooves 15 are opened on both sides of the inner wall of the lifting groove 14, the surface of the slider 1602 is movably installed on the inner wall of the slide groove 15, the surface of the warning plate 1601 is opened with a slope 2 1603, and the bottom of the inner wall of the outdoor panel 8 is opened with a slope 1 802.

[0028] Specifically: when the sealing plate 13 is opened, the warning plate 1601 is lowered by gravity, and the sliders 1602 fixedly installed on both sides of the warning plate 1601 slide in the inner wall of the slide 15, making the descent more stable. The warning plate 1601 is restricted by the slider 1602 and the slide 15, and stops descending after descending to the limit point. The warning plate 1601 is used to warn the staff. After the gas is discharged, the electric telescopic rod 12 contracts and drives the sealing plate 13 to be retracted. The warning plate 1601 is squeezed between the inclined surface 2 1603 on the surface of the warning plate 1601 and the inclined surface 1 802 on the inner wall of the groove 801, so that the warning plate 1601 is raised and retracted, so that the device can remind the staff as the device is used, making the device more perfect.

[0029] Working principle: embed the channel body 1 into the wall, fit it to the wall through the mounting plate 2, and fix it with screws to make the device stably installed on the wall. Embed the mounting block 9 fixed on the other side of the outdoor panel 8 into the inner wall of one end of the channel body 1, so that each threaded hole 10 is aligned with its corresponding threaded groove 7. Fix the outdoor panel 8 to one end of the channel body 1 by tightening the bolt 11, and the device is installed. When the device starts to be used, after the fire in the machine room is extinguished by gas, the pressure sensitive valve 6 is the AR2000 series of AirTac. The pressure difference between the inside and outside of the machine room is detected by the pressure sensitive valve 6. When the outdoor air pressure is higher than the air pressure in the machine room, the data is transmitted to the controller through the pressure sensitive valve 6, and the controller controls the start to open the round hole 5 to allow gas to enter. At the same time, the data is transmitted to the controller, and the controller starts the electric telescopic rod 12 to make the sealing plate 13 move from the inner wall of the groove 801. When the air pressure inside the machine room is released, the device no longer needs an external power source, and the device automatically opens by utilizing the pressure difference between the inside and outside of the machine room, thereby realizing rapid air release and making the device more perfect; when the sealing plate 13 extends from the inner wall of the groove 801, the warning plate 1601 is lowered by gravity, and the sliders 1602 fixedly installed on both sides of the warning plate 1601 slide in the inner wall of the slide 15, making the descent more stable, and the restriction between the sliders 1602 and the slide 15 makes the warning plate 1601 stop descending after the limit point, and the warning plate 1601 is used to warn the staff. After the gas is discharged, the electric telescopic rod 12 contracts and drives the sealing plate 13 to retract, and is squeezed between the inclined surface 2 1603 on the surface of the warning plate 1601 and the inclined surface 1 802 on the inner wall of the groove 801, so that the warning plate 1601 is raised and retracted, so that the device can be used to remind the staff as the device is used, making the device more perfect.
