Description

Technical Field

[0001] This utility model belongs to the field of fire protection facilities technology, and in particular relates to a data center gas fire extinguishing system that improves fire extinguishing efficiency. Background Technology

[0002] A data center is a collection of physical facilities used for centralized storage, management, processing and transmission of large-scale data. Essentially, it is a "data hub" that integrates hardware devices, software systems and supporting infrastructure.

[0003] Because data centers involve large-scale electronic equipment, their fire protection systems typically use gas extinguishing systems.

[0004] For existing fire extinguishing systems, the typical setup involves placing fire extinguishing gas cylinders in a specific room and connecting them via pipes so that the gas in the cylinders can enter the room to extinguish the fire. However, in existing gas extinguishing systems, the arrangement of the gas outlets in the pipes is irregular. When a fire occurs, gas is released along each outlet, filling the room from top to bottom in a large-area coverage manner. The total amount of gas released per unit time is affected by the size of the gas pipe opening and the output gas pressure. In data centers, the ignition point is often a single point caused by overheating, short circuits, etc. The principle of a solution where all outlets release gas simultaneously is to create an oxygen-deficient asphyxiating state in the overall indoor environment, thereby preventing the fire from spreading. This process is adapted to the gas release time (under national standards, the gas release time is generally required to be less than 60 seconds, which is also within the time limit for filling the room in a typical data center). In scenarios where expensive equipment such as data centers are located, being able to suppress the spread of fire even by one second can save a lot of losses.

[0005] Therefore, a solution is needed that can quickly suppress the ignition point to prevent its spread. Utility Model Content

[0006] The purpose of this invention is to provide a data center gas fire suppression system that improves fire suppression efficiency, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a data center gas fire extinguishing system for improving fire extinguishing efficiency, comprising a fire extinguishing agent storage cylinder, a control and activation valve group, a delivery pipeline, nozzles, and a fire detection system. The delivery pipeline is connected to the fire extinguishing agent storage cylinder and sprays gas into the room through the nozzles. The control and activation valve group is used to control the connection and closure between the fire extinguishing agent storage cylinder and the delivery pipeline. Several branch pipelines are connected to the delivery pipeline, and each branch pipeline has a nozzle connected to its outlet. Each nozzle is responsible for covering a gas area, and the area covered by all the nozzles covers the entire area of ​​the room. The gas extinguishing system also includes a monitoring system and a pipeline control switch. The pipeline control switch can control the opening and closing of each branch pipeline. The monitoring system can identify the area where the ignition point is located. The pipeline control switch is used to control the opening of the branch pipeline in the area where the ignition point is located.

[0008] Preferably, there is an overlap between the areas served by adjacent nozzles.

[0009] Preferably, the outlets of all the branch pipes 1 in the room are arranged in a horizontal and vertical manner, and a branch pipe 2 with a nozzle connected to the delivery pipe is set in the center of the square area formed by the outlets of four adjacent branch pipes 1.

[0010] Preferably, a gas guide hood is installed at the outlet of the branch pipeline, and the gas guide hood is flared downwards.

[0011] Preferably, the control start valve group includes a start solenoid valve, which is electrically connected to the on-site gas extinguishing start button and the fire control room host. The start solenoid valve can control the connection and / or closure between the extinguishing agent storage cylinder and the delivery pipeline by either the on-site gas extinguishing start button or the fire control room host issuing a start signal.

[0012] The beneficial effects of this utility model are as follows: This solution identifies the area where the fire originates through a monitoring system, and then controls the switch of the branch pipe covering that area through a pipeline control switch. This allows the extinguishing gas to preferentially cover the area where the fire originates and disperse until it fills the entire room. This process causes the concentration of the extinguishing gas in the area where the fire originates to rise rapidly, thereby suppressing the fire. Compared with existing solutions, this solution achieves a higher concentration of extinguishing gas in the area where the fire originates within the same time frame, effectively suppressing the spread of the fire and preventing greater economic losses. Furthermore, the design must ensure that the appropriate pipe diameter and nozzle of the branch pipe are selected within a limited time (e.g., the national standard requirement of 60 seconds) to ensure that the overall concentration of the extinguishing gas in the room meets the standard within the specified time. The design incorporates overlapping areas between adjacent nozzles, allowing the pipeline control switch to simultaneously control the ignition point in the overlapping area to cover all branch pipelines in that area. This is implemented because the extinguishing gas concentration at the edge of each area tends to be lower than that at the center due to its diffusion. By setting overlapping areas and controlling the opening of all branch pipelines covering those overlapping areas, the overlapping area is prevented from becoming an edge area, effectively ensuring that the extinguishing gas concentration in that area remains at a high level within a given time. In this system, branch pipe two is installed in a position that allows it to cover the area where the four branch pipes one intersect, forming a square area. This means that when a fire occurs in the area covered by the four branch pipes one, firefighting can be carried out quickly by simply opening branch pipe two. This avoids the need to open all four branches when a fire occurs in that area, which would prevent the rapid increase of the extinguishing gas concentration at the fire point from being insufficient. This solution incorporates a gas guide hood, which effectively directs the gas sprayed from the nozzle to cover its designated area, resulting in a more concentrated spray range and a higher concentration of extinguishing gas within the area per unit time. This, in turn, enables rapid suppression of the fire. Attached Figure Description

Detailed Implementation

[0014] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention. Example

[0015] See Figures 1-3 A data center gas fire suppression system for improved fire extinguishing efficiency includes a fire extinguishing agent storage cylinder, a control valve assembly, a delivery pipeline, nozzles, and a fire detection system. The delivery pipeline is connected to the fire extinguishing agent storage cylinder and sprays gas into the room through the nozzles. The control valve assembly controls the connection and closure between the fire extinguishing agent storage cylinder and the delivery pipeline. Several branch pipelines are connected to the delivery pipeline, and each branch pipeline has a nozzle connected to its outlet. Each nozzle is responsible for covering a specific area with gas, and the area covered by all the nozzles covers the entire area of ​​the room. There are many existing solutions for connecting and controlling the fire extinguishing agent storage cylinder, control valve assembly, delivery pipeline, nozzles, and fire detection system, which will not be specifically described here. Specific modifications to this solution based on existing technologies will be explained in detail below.

[0016] The gas extinguishing system also includes a monitoring system and a pipeline control switch. The pipeline control switch can control the opening and closing of each branch pipeline. The monitoring system can identify the area where the ignition point is located. The pipeline control switch is used to control the opening of the branch pipeline in the area where the ignition point is located. Specifically, the monitoring system can be a video monitoring system built into the data center. The pipeline control switch can be a solenoid valve. The solenoid valve can be a multi-position multi-way solenoid valve to enable one solenoid valve to control the opening and closing of one or more branch pipelines in multiple branch pipelines. Alternatively, one solenoid valve can be configured for each branch pipeline. By cooperating with the monitoring system to identify the area where the ignition point is located, the pipeline control switch opens the branch pipeline covering the area of ​​the ignition point and then waits.

[0017] There are overlapping areas between the areas served by adjacent nozzles.

[0018] The outlets of all the branch pipes 7 in the room are arranged in a horizontal and vertical manner. A branch pipe 7 with a nozzle connected to the delivery pipe is set in the center of the square area formed by the outlets of four adjacent branch pipes 7.

[0019] Among them, see Figure 4 A gas guide hood is installed at the outlet of branch pipe one and / or branch pipe two, and the gas guide hood is flared downwards.

[0020] The control valve assembly includes a solenoid valve for starting, which is electrically connected to the on-site gas extinguishing start button and the fire control room host. The solenoid valve can control the connection and / or closure between the extinguishing agent storage cylinder and the delivery pipeline by either the on-site gas extinguishing start button or the fire control room host. This is a conventional solution and will not be described here.

[0021] The specific design and operation methods will be explained below: The fire detection system includes smoke detectors, heat detectors, and other facilities. It is connected to a central control center (i.e., a computer) via electrical (gas) lines, together with the control and start valve group, monitoring system, and pipeline control switch. The central control center has relevant control rules programmed in it so that each department can operate according to the required rules. This is a conventional technology. The solution for the monitoring system to identify the fire point can be integrated with existing big data models for image recognition and positioning.

[0022] The control rules are as follows: the non-intersecting area within the nozzle's coverage area is called the absolute control area, and the intersecting area is called the weak control area. In this scheme, taking a rectangular area covered by the nozzle as an example, in a system without a gas guide hood, the maximum rectangular area it can cover is considered the coverage area. In a system with a gas guide hood, the gas guide hood is designed as a truncated pyramid shape to ensure that the coverage area is rectangular to the greatest extent possible. Figure 1 The illustration shown illustrates the nozzle gas coverage area of ​​the region formed by the outlets of four branch pipes (p and q). Specifically, in the diagram, the areas covered by the four branch pipes are the rectangular areas jointly formed by AGE, BEF, CGH, and DFH. E, F, G, and H intersect in a central area (the rectangle enclosed by the thin dashed lines in the diagram), which also belongs to the coverage area of ​​the four branch pipes. The actual coverage area of ​​branch pipe 2 is the rectangular area formed by the thick solid lines I and J. Since the extinguishing gas concentration at the edge of the area is lower than that in the central area per unit time, to ensure the fire suppression effect, I is designated as the absolute control area of ​​the nozzle at the outlet of branch pipe 2. No weak control area is set for the nozzle at the outlet of branch pipe 2. The annular area enclosed by J only indicates its coverage area. A- (the area where A intersects with I) is designated as the absolute control area of ​​the nozzle at the outlet of branch pipe 1. The area is defined as follows: B- (the area where B intersects with I) is the absolute control area for the outlet nozzle of the branch pipe; C- (the area where C intersects with I) is the absolute control area for the outlet nozzle of the branch pipe; and D- (the area where D intersects with I) is the absolute control area for the outlet nozzle of the branch pipe. When a fire is detected, the corresponding solenoid valve in the absolute control area of ​​each nozzle controls the opening of the branch pipe (II). In the weak control area, such as E at the intersection of AB, if it is within the range of I, then the branch pipe II responsible for the range of I is opened. If the ignition point is located in the intersection range of EJ, then both the branch pipe I and the branch pipe II responsible for A, B, and I are opened. If it is only within the range of the intersection point E of A and B, then the branch pipe I responsible for A and B is opened. The rules for the ranges AC, CD, and BD are the same as for AB.

[0023] The structure provided in this solution, when used in conjunction with the aforementioned rules, enables the suppression of a fire by rapidly increasing the concentration of extinguishing gas in the area where the fire originated, thus better preventing greater economic losses.

Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
