Description

Technical Field

[0001] This utility model relates to the field of gas fire extinguishing technology, and in particular to a prefabricated gas fire extinguishing system. Background Technology

[0002] Prefabricated gas fire extinguishing systems are widely used in engineering projects to protect areas unsuitable for automatic sprinkler systems, such as electrical rooms, substations, battery rooms, and data centers. Prefabricated gas fire extinguishing systems (also known as pipeless fire extinguishing systems) refer to fire extinguishing devices that pre-design and assemble extinguishing agent storage devices, discharge components, and control systems into a complete set of equipment, possessing automatic fire detection and linkage activation functions. Their core advantages are:

[0003] 1) Rapid response: The extinguishing agent is pre-filled and automatically released during a fire, requiring no manual intervention;

[0004] 2) Flexible deployment: No complex piping network is required, making it suitable for locations with limited space or where renovation is difficult;

[0005] 3) Scene adaptability: Widely used in water-sensitive places such as data centers, substations, battery rooms, and archives.

[0006] Although prefabricated gas fire suppression systems are widely used, their design flaws limit their actual fire suppression effectiveness. For example... Figures 1-2 As shown, traditional prefabricated gas fire extinguishing systems use a gas cylinder 1 and nozzle 2 integrated into a cabinet 3. The nozzle 1 is located at the top of the cabinet 3, which has a limited height and a fixed angle, making it impossible to adjust the spray direction. It is also easily blocked by other equipment (such as electrical cabinets) around the cabinet 3, affecting the uniform diffusion of the gas and resulting in uneven gas concentration in the room, leading to unsatisfactory fire extinguishing effect. Utility Model Content

[0007] The purpose of this invention is to provide a prefabricated gas fire extinguishing system that enables the extinguishing agent to effectively avoid obstacles such as electrical cabinets, thereby quickly, efficiently and evenly filling the enclosed space, thus minimizing the occurrence and harm of fire accidents.

[0008] To achieve the above objectives, this utility model provides a prefabricated gas fire extinguishing system, including a storage cabinet and at least one fire extinguishing device. The fire extinguishing device includes a gas cylinder, a connecting branch pipe, a discharge horizontal pipe, and at least one nozzle. The gas cylinder is located inside the storage cabinet and is used to store the fire extinguishing agent. The two ends of the connecting branch pipe are respectively connected to the gas cylinder and the discharge horizontal pipe, and the connecting branch pipe extends vertically through the storage cabinet. The discharge horizontal pipe is horizontally arranged above the storage cabinet, and the nozzle is rotatably arranged at the end of the discharge horizontal pipe opposite to the connecting branch pipe.

[0009] Optionally, the connecting branch pipe includes a vertically connected spray vertical pipe and a high-pressure hose. One end of the high-pressure hose is connected to the outlet of the gas storage cylinder, and the other end is connected to one end of the spray vertical pipe. The other end of the spray vertical pipe is connected to the spray horizontal pipe.

[0010] Optionally, the spray vertical pipe and the spray horizontal pipe are connected by a 90° elbow.

[0011] Optionally, both the spray vertical pipe and the spray horizontal pipe are seamless steel pipes.

[0012] Optionally, the diameter of the spray vertical pipe and the spray horizontal pipe is DN25 or DN32.

[0013] Optionally, the length of the spray pipe is 1-5m.

[0014] Optionally, the end of the discharge horizontal pipe opposite to the connecting branch pipe is provided with two nozzles, and the discharge angles of the two nozzles are different.

[0015] Optionally, the two nozzles are arranged in a T-shape or Y-shape relative to the discharge cross tube.

[0035] Example 1

[0036] Please refer to Figures 3-4 This embodiment provides a prefabricated gas fire extinguishing system, including a storage cabinet 100 and a fire extinguishing device. The fire extinguishing device includes a gas cylinder 210, a connecting branch pipe 220, a discharge horizontal pipe 230, and a nozzle 240. The gas cylinder 210 is located inside the storage cabinet 100 and is used to store the fire extinguishing agent. The two ends of the connecting branch pipe 220 are respectively connected to the gas cylinder 210 and the discharge horizontal pipe 230, and the connecting branch pipe 220 penetrates the storage cabinet 100 vertically. The discharge horizontal pipe 230 is horizontally arranged above the storage cabinet 100. The nozzle 240 is rotatably arranged at the end of the discharge horizontal pipe 230 away from the connecting branch pipe 220.

[0037] The working principle of the prefabricated gas fire extinguishing system provided in this embodiment is as follows:

[0038] When a smoke / heat detector in the protected area detects a fire signal, it transmits the signal to the gas extinguishing controller. Upon receiving the fire signal, the controller enters a delay phase (usually 30 seconds) for personnel evacuation and shutdown of linked equipment (such as ventilation systems and fire dampers). After the delay, the controller outputs a start signal to open the solenoid valve, allowing the extinguishing agent to flow from the gas cylinder 210 through the connecting branch pipe 220 and the discharge horizontal pipe 230 before being discharged from the nozzle 240.

[0039] This invention adds a horizontal discharge pipe 230 to the traditional prefabricated gas fire extinguishing system. The appropriate length of the horizontal discharge pipe 230 is selected according to the protection environment and surrounding equipment. At the same time, it is equipped with an adjustable nozzle 240, which enables the fire extinguishing gas to effectively avoid obstacles such as electrical cabinets, and thus quickly, efficiently and evenly fill the enclosed space, thereby minimizing the occurrence and harm of fire accidents.

[0040] In this embodiment, a siphon tube is provided inside the gas storage cylinder 210. The siphon tube extends from the bottom of the gas storage cylinder 210 to the outlet of the container valve to ensure that the extinguishing agent is completely drawn out from the bottom of the cylinder and to avoid residue.

[0041] In this embodiment, the connecting branch pipe 220 includes a vertically connected spray vertical pipe 221 and a high-pressure hose 222. One end of the high-pressure hose 222 is connected to the outlet of the gas storage cylinder 210, and the other end is connected to one end of the spray vertical pipe 221. The other end of the spray vertical pipe 221 is connected to the spray horizontal pipe 230.

[0042] In this embodiment, both the spraying vertical pipe 221 and the spraying horizontal pipe 230 are seamless steel pipes, and the spraying vertical pipe 221 and the spraying horizontal pipe 230 are connected by a 90° elbow.

[0043] In this embodiment, the diameters of the spray vertical pipe 221 and the spray horizontal pipe 230 are DN25 or DN32.

[0044] Optionally, the length of the horizontal spray pipe 230 is 1-5m, and its length can be selected according to the requirements. This utility model does not limit this length.

[0045] In this embodiment, the nozzle 240 is rotatably disposed at the end of the spray horizontal pipe 230 opposite to the connecting branch pipe 220. Its rotatable structural design is similar to that of a shower head, allowing for adjustment of the spray angle according to the surrounding environment; this will not be described in detail here.

[0046] Preferably, the extinguishing agent stored in the gas cylinder 210 is heptafluoropropane or perfluorohexanone.

[0047] Example 2

[0048] Please refer to Figures 5-6 The difference from the above embodiment 1 is that in this embodiment, the end of the discharge horizontal pipe 230 away from the connecting branch pipe 220 is provided with two nozzles 240 and the discharge angles of the two nozzles 240 are different. This design makes the discharge range of the extinguishing agent wider, and can fill the enclosed space more quickly, efficiently and evenly, thereby minimizing the occurrence and harm of fire accidents.

[0049] Optionally, the two nozzles 240 are arranged in a T-shape or Y-shape relative to the horizontal spray pipe 230. In this embodiment, the two nozzles 240 are arranged in a T-shape relative to the horizontal spray pipe 230, that is, the two nozzles 240 extend in opposite directions, which can be vertical or horizontal, and the present invention does not limit this.

[0050] Example 3

[0051] Please refer to Figures 7-8The difference from the above embodiment is that, in this embodiment, two fire extinguishing devices are arranged side by side inside the storage cabinet 100, and the nozzles 240 of the two fire extinguishing devices have different spray angles. For larger enclosed spaces, at least two fire extinguishing devices can be arranged side by side inside the storage cabinet 100 to ensure that sufficient extinguishing agent is released in a short time. It should be noted that, depending on actual needs, the spray angles of the nozzles 240 of the two fire extinguishing devices can be the same, such as being arranged in parallel, or they can be different, such as being arranged opposite each other; this utility model does not impose any restrictions on this. In addition, the lengths of the connecting branch pipes 220 and the spray horizontal pipes 230 of the different fire extinguishing devices can be the same or different; this utility model also does not impose any restrictions on this.

[0052] Example 4

[0053] Please refer to Figures 9-10 The difference from the above embodiments is that, in this embodiment, the containment cabinet 100 is equipped with two fire extinguishing devices, and each fire extinguishing device has two nozzles 240 at the end of its discharge horizontal pipe 230 that is away from the connecting branch pipe 220. This design allows for a wider discharge range of the fire extinguishing agent and enables the simultaneous discharge of sufficient fire extinguishing agent in a short time, thereby filling the enclosed space more quickly, efficiently, and evenly, and minimizing the occurrence and damage of fire accidents.

[0054] In summary, this utility model embodiment provides a prefabricated gas fire extinguishing system. Based on the traditional prefabricated gas fire extinguishing system, a discharge horizontal pipe 230 is added. By selecting a suitable length of discharge horizontal pipe 230 according to the protection environment and surrounding equipment, and at the same time matching it with an angle-adjustable nozzle 240, the fire extinguishing agent can effectively avoid obstacles such as electrical cabinets, thereby quickly, efficiently and evenly filling the enclosed space, thus minimizing the occurrence and harm of fire accidents.

[0055] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
