Description

Technical Field

[0001] This utility model belongs to the field of fire safety technology, specifically relating to a novel gas extinguishing system testing device and method. Background Technology

[0002] With the increasing number of large-space buildings such as archives, libraries, and data centers, fires can spread rapidly due to their open spaces and limited fire compartments, necessitating the mandatory installation of fire suppression systems. Water sprinkler systems are unsuitable for locations with stringent environmental requirements, such as archives, due to the risk of water damage; therefore, gaseous fire suppression systems have become the core safeguard.

[0003] Standardized testing platforms for gas extinguishing systems are core supporting tools for research and development. US UL, European EN standards, and my country's GB25972-2024 all have technical requirements for them. However, existing technologies have significant shortcomings and are unable to meet the testing needs of large-space scenarios.

[0004] Insufficient spatial adaptability: Existing patents (such as CN117116130A, CN118079299A, CN115148084A) do not clearly address the issue of sensor deployment in large spaces, or the test space is limited to 100-200m³, making it impossible to simulate the diffusion pattern of fire extinguishing agents in large spaces of more than 1000m³.

[0005] Low accuracy and limited dimensions of parameter measurement: Existing technologies (such as CN115713831A) rely heavily on temperature and oxygen concentration to determine the fire extinguishing effect, but do not cover core indicators such as fire extinguishing agent concentration and heat flux intensity, and cannot fully reflect the distribution of temperature and concentration fields.

[0006] In summary, existing testing platforms suffer from common defects such as lack of spatial adaptability, insufficient and unreasonable layout of testing points, and inadequate parameter measurement dimensions. As a result, these testing platforms are unable to achieve accurate fire extinguishing effects, which hinders the development of new fire extinguishing systems. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a novel gas fire extinguishing system testing device, which solves the technical problems of the lack of a dedicated gas fire extinguishing system testing device for large spaces, the limited parameters of existing gas fire extinguishing system testing devices, and insufficient spatial information of parameters.

[0008] To achieve the above objectives, this utility model provides a novel gas extinguishing system testing device, comprising a platform body, a fire detection unit, a gas extinguishing unit, and a control unit.

[0009] The main body of the platform comprises a large internal space, which is greater than or equal to 1000m². 3It has an ignition unit at its bottom, which includes fuel and a burner;

[0010] The fire detection unit includes a multi-parameter sensing device and an image acquisition device. The multi-parameter sensing device includes a fixed integrated sensor and a mobile integrated sensor arranged in a grid on the top of the main body of the platform.

[0011] The gas extinguishing unit includes a gas extinguishing agent storage module and a gas extinguishing agent release and distribution module. The gas extinguishing agent release and distribution module is used to release the gas extinguishing agent from the gas extinguishing agent storage module to the fire source for extinguishing.

[0012] The control unit includes a server and a control cabinet. The server communicates with the fire detection unit, the gas extinguishing unit, and the burner through the control cabinet.

[0013] Large space greater than or equal to 1000m 3 The aim is to fully simulate the large spaces of large data centers and library archives. In some implementations, the large space is no less than 3000m². 3 .

[0014] In some implementations, the platform's main structure includes a portal reinforced concrete building, comprising load-bearing columns, beams, walls, a floor, and a roof. The load-bearing columns and beams are reinforced concrete structures of at least 80 cm x 80 cm. The walls are constructed of fire-resistant bricks with a thickness of at least 60 cm, and the inner and outer surfaces are plastered with concrete to a thickness of at least 10 mm. The walls have a compressive strength of at least 3000 Pa. The roof is a reinforced concrete structure at least 15 cm thick, with a compressive strength of at least 1800 Pa and a load capacity of at least 2500 Pa. The floor is a reinforced concrete structure at least 30 cm thick, and the foundation pits for the load-bearing columns are at least 1.6 m deep. This ensures that the building structure can withstand high temperatures, smoke pressure, extinguishing agent impact, and the reaction force of the nozzles during testing, preventing structural deformation, collapse, or cracking.

[0015] Furthermore, both fixed and / or mobile integrated sensors include integrated sensors, such as extinguishing agent concentration sensors, carbon monoxide concentration sensors, oxygen concentration sensors, smoke concentration sensors, temperature sensors, heat flow sensors, and wind speed sensors, to obtain comprehensive fire parameter data and accurately determine the fire situation.

[0016] Furthermore, the image acquisition device is a camera, preferably an AI camera, used to identify flames.

[0017] Furthermore, the multi-parameter sensing device also includes a slide rail, along which the movable integrated sensor can move.

[0018] Preferably, the slide rail is configured as a grid-like slide rail, and the mobile integrated sensor further includes a sliding telescopic device. The sliding telescopic device comprises a pulley assembly and a telescopic assembly. Multiple integrated sensors with adjustable spacing are mounted on the telescopic assembly. The telescopic assembly is connected to the pulley assembly and moves by being suspended from the grid-like slide rail via the pulley assembly. The collaboration between the grid-like slide rail and the mobile integrated sensor with the telescopic assembly sliding within the grid-like slide rail facilitates the acquisition of detailed data on fire scene spatial parameters such as temperature and concentration fields in large spaces.

[0019] In some embodiments, the telescopic assembly is configured as a telescopic sleeve structure, with an integrated sensor mounted on the exterior of each sleeve section. The signal and power lines of the integrated sensors are connected to the control cabinet through the interior of the telescopic sleeve. Alternatively, the telescopic assembly is configured as a diamond-shaped telescopic structure, with integrated sensors positioned at the joint nodes between several sets of diamond structures. The signal and power lines of the integrated sensors are connected to the control cabinet through wiring within the diamond structures. All of the above telescopic assembly structures allow for adjustable spacing between the multiple integrated sensors on the telescopic assembly, thereby obtaining an integrated sensor array with a suitable vertical spacing.

[0020] Obviously, in some of these implementations, the integrated sensor can also be connected to the control unit via wireless communication, which can be one or more of ZigBee, WirelessHART, LoRa, NB-IoT, and BLE.

[0021] In some of these implementations, the integrated sensor may also utilize a mobile power source.

[0022] In some of the embodiments, a ventilation and smoke exhaust unit is also included, which includes smoke exhaust outlets distributed on the upper part of the main wall of the platform, smoke exhaust ducts connected to the smoke exhaust outlets, smoke exhaust ducts connected to one or more smoke exhaust fans, smoke exhaust valves installed on the smoke exhaust ducts, and all smoke exhaust fans and smoke exhaust valves connected to the control cabinet.

[0023] In some embodiments, an alarm unit is also included, comprising an audible and visual alarm, a public address system, and an evacuation indicator. The alarm unit is communicatively connected to the control cabinet. The alarm unit is configured to receive a signal from the control unit indicating a fire and issue an alarm.

[0024] In some embodiments, the gas extinguishing agent storage module (32) includes multiple storage cylinders for storing extinguishing agent gas. These cylinders are arranged in an array and interconnected via manifolds to form a storage cylinder group, stored in a cylinder room outside the main platform. Weight sensors are installed below each storage cylinder and are communicatively connected to the control cabinet to transmit the weight of the cylinders to the control unit in real time for calculating gas consumption and gas consumption rate. The array arrangement of the storage cylinders, interconnected via manifolds, forms a redundant supply network, ensuring normal system operation even in the event of a single storage cylinder failure.

[0025] Furthermore, each storage cylinder is equipped with a pressure regulating valve and a safety relief device to ensure sufficient extinguishing agent volume and release pressure for large space requirements.

[0026] In some embodiments, the gaseous extinguishing agent release and distribution module includes extinguishing agent pipelines and nozzles. The extinguishing agent pipelines include internal and external pipelines. The internal pipelines are fixed to the roof of the platform body and extend in an "I" shape. The external pipelines connect to the gaseous extinguishing agent storage module to introduce the extinguishing agent into the internal pipelines. The nozzles are installed at the ends of the "I"-shaped structures of the internal pipelines, no more than 0.5m from the roof. The nozzles are communicatively connected to the control cabinet. The density of the internal pipelines can be increased according to the building area to ensure extinguishing agent pipeline coverage of the space.

[0027] In a preferred embodiment, the nozzles are configured as rotatable nozzles, and the number installed is determined based on the maximum nozzle protection area. In some embodiments, the nozzles are equipped with pressure sensors. In some embodiments, the control cabinet controls the nozzles to be fixed or rotated, or to adjust the spray pressure.

[0028] As an example, the control cabinet can acquire sensor electrical signals transmitted by the fire detection unit through internal interfaces (analog and / or digital interfaces), convert them into fire parameter data or values ​​that the server can recognize, and transmit the processed fire parameter data or values ​​to the server through wired or wireless communication modules. When the server issues a command, the control cabinet receives the command and converts it into control signals, such as controlling the nozzle drive motor of the gas extinguishing system, controlling the start / stop and power of the ignition unit, controlling the start / stop and variable frequency speed control of the ventilation and smoke exhaust unit, opening or closing the smoke exhaust valve, and responding to the alarm unit.

[0029] The technical solution of this utility model has at least the following beneficial effects:

[0030] 1. This utility model constructs a test device for a large-space fire extinguishing system, wherein the volume of the large space is not less than 1000m³. 3This system fully simulates the large spaces of data centers and library archives, realistically reflecting the temperature and concentration fields of such spaces. Furthermore, the platform's main building structure can withstand loads such as high temperatures, smoke pressure, extinguishing agent impact, and nozzle spray reaction force, preventing structural deformation, collapse, or cracking, making it suitable for testing large-space fire extinguishing systems.

[0031] 2. The fire detection unit of this utility model includes a fire extinguishing agent concentration sensor, a carbon monoxide concentration sensor, an oxygen concentration sensor, a smoke concentration sensor, a temperature sensor, a heat flow sensor, a wind speed sensor, and an image acquisition device. Compared with the prior art, which mainly relies on a few parameters such as temperature, oxygen concentration, and smoke concentration to determine fires, resulting in data distortion, this utility model can monitor multiple parameters and verify each other, achieving accurate measurement of fire parameters and accurate determination of fire status. This enables comprehensive monitoring and storage of fire information, facilitating accurate determination of fire status.

[0032] 3. The multi-parameter sensing device of this utility model includes a fixed integrated sensor and a mobile integrated sensor arranged in a grid in a large space, a grid-arranged slide rail and a mobile integrated sensor with a telescopic component that slides in the grid-arranged slide rail, and multiple integrated sensors with adjustable spacing set on the telescopic component. It expands traditional single-point or surface measurement data to multi-parameter spatial three-dimensional fire data, realizes three-dimensional measurement of multiple points with a small number of sensors, and facilitates obtaining detailed data of the spatiotemporal characteristic parameters of the fire scene near the fire source.
