Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fire extinguishing equipment technology, and in particular relates to a fire detection gas extinguishing device. Background Technology
[0002] A gaseous fire extinguishing device is a fire-fighting equipment that uses a gaseous extinguishing agent to extinguish fires. It is widely used in various places and industries. The following is a detailed introduction to gaseous fire extinguishing devices: Working Principle Gaseous fire extinguishing devices mainly extinguish fires through the following two methods: Asphyxiation: By releasing inert gases (such as carbon dioxide, nitrogen, argon, etc.), the oxygen concentration around the fire source is diluted, reducing the oxygen concentration to a level that cannot support combustion, thereby extinguishing the flames.
[0003] However, current gas fire extinguishing devices automatically extinguish fires by monitoring the fire source, which has certain limitations. Some fires are formed by the generation of a large amount of dense smoke first. Automatic fire extinguishing by monitoring the fire source does not provide adequate protection against dense smoke and often lacks early warning capabilities. Therefore, improvements are needed. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this invention is to provide a fire detection gas extinguishing device.
[0005] To achieve the above objectives, this utility model proposes a fire detection gas extinguishing device, including a gas storage tank. A discharge pipe is installed at the center of the bottom of the gas storage tank, a connecting pipe is installed on the side of the discharge pipe, a telescopic rod is installed on the left side of the connecting pipe, a data evaluation module is installed below the telescopic rod, a warning light is installed on the left side of the data evaluation module, a fire source monitor is installed on the right end of the data evaluation module, and a smoke sensor is installed below the data evaluation module.
[0006] In one example, a mounting plate is installed at the center of the top of the gas storage tank, and slots are provided at the four corners of the top of the mounting plate.
[0007] In one example, the gas storage tank has two lifting rings on both sides of its top, and the two lifting rings are the same size.
[0008] In one example, an air inlet is provided at the center of the top of the mounting plate.
[0009] In one example, the bottom end of the discharge pipe is connected to a nozzle, and a circular groove is formed around the bottom end of the nozzle.
[0010] In one example, a pressure gauge is installed at the left end of the discharge pipe.
[0011] In one example, the other end of the telescopic rod passes through the connecting pipe and the discharge pipe and extends to the right end of the discharge pipe, and a round cap is fitted onto the outer surface of the other end of the telescopic rod.
[0012] The fire detection gas extinguishing device proposed in this utility model can bring the following beneficial effects:
[0013] 1. Fire source monitoring uses thermal imaging and temperature capture to detect open flames, and the data is transmitted to the control center's data evaluation module for assessment. If the data matches the settings within the data evaluation module, it will send an electrical signal. This signal is transmitted to the telescopic boom, releasing the seal on the connecting pipe at the bottom of the gas cylinder. Under the pressure difference, the extinguishing gas is then discharged through the nozzle, extinguishing the fire. Simultaneously, the electrical signal is transmitted to the alarm's warning light, triggering the alarm and sending a distress signal to the nearest fire station. In some fires, dense smoke is initially produced; the gas sensor will detect the smoke and transmit the data to the data evaluation module. If the fire extinguishing conditions are met, the data evaluation module again sends signals to the telescopic boom and warning light, initiating the fire extinguishing and alarm procedures. Through the dual monitoring of fire source monitoring and gas sensors, fire prevention is effectively achieved, enhancing safety performance. Attached Figure Description

[0020] To more clearly illustrate the overall concept of this utility model, a detailed description is provided below with reference to the accompanying drawings.
[0021] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "a solution," "some solutions," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that solution or example is included in at least one solution or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same solution or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.
[0025] like Figures 1-4As shown in the figure, an embodiment of this utility model proposes a fire detection gas extinguishing device, which includes a gas storage tank 1. In use, the operator first needs to hang the gas storage tank 1 on the top of the roof. An installation plate 10 is installed at the center of the top of the gas storage tank 1. At the same time, slots 11 are opened at the four corners of the top of the installation plate 10. The operator can then fix the gas storage tank 1 to the wall of the roof by passing expansion bolts through the slots 11. Next, in order to improve the fixing effect, the operator sets up two lifting rings 9 on both sides of the top of the gas storage tank 1. The two lifting rings 9 are the same size and have round holes. The operator can then pass ropes through the round holes on the lifting rings 9 and hang the ropes on the wall to improve the fixing effect. A gas filling port 12 is set at the center of the top of the installation plate 10. Inert gas carbon dioxide can be filled into the gas storage tank 1 through the gas filling port 12.
[0026] Then, an exhaust pipe 2 is installed at the center of the bottom of the gas storage tank 1. A nozzle 8 is connected to the bottom of the exhaust pipe 2. A ring is formed around the bottom of the nozzle 8. This design allows the gas from the gas storage tank 1 to be sprayed evenly in all directions instead of in a straight line, thus achieving rapid fire extinguishing. Next, the operator installs a connecting pipe 14 on the side of the exhaust pipe 2. A telescopic rod 3 is installed on the left side of the connecting pipe 14. The other end of the telescopic rod 3 passes through the connecting pipe 14 and the exhaust pipe 2 and extends to the right end of the exhaust pipe 2. A round cap is fitted on the outer surface of the other end of the telescopic rod 3. The telescopic rod 3 is controlled by a data evaluation module 4 installed below it. A pressure gauge 13 is installed on the left end of the exhaust pipe 2 to monitor the pressure inside the gas storage tank 1. By monitoring the internal pressure of the gas storage tank 1 through the pressure gauge 13, it is ensured that the gas storage tank 1 is in a normal working state.
[0027] When an open flame appears indoors in the gas extinguishing system, the fire source monitoring 6 installed on the right side of the data evaluation module 4 will perform thermal imaging processing on the open flame and capture its surface temperature. After processing, the data will be transmitted to the data evaluation module 4 for evaluation. If it meets the definition of fire data, an electrical signal will be sent to the telescopic rod 3, causing the telescopic rod 3 to move and release the seal on the bottom connecting pipe 14 of the gas storage tank 1. Under the action of internal and external pressure, the gas in the gas storage tank 1 will be discharged through the nozzle 8 to extinguish the fire. At this time, the electrical signal will not only be transmitted to the telescopic rod 3, but also to the warning light 7 installed on the left side of the telescopic rod 3. The warning light 7 will then trigger an alarm and quickly send information to the nearby fire station for assistance to prevent the accident from escalating.
[0028] During the evolution of some fires, visible smoke will be generated. The smoke sensor 5, located below the bottom of the data evaluation module 4, will detect this smoke. The data from the smoke sensor 5 will be transmitted to the data evaluation module 4, which will then evaluate the fire. If the fire meets the fire extinguishing procedure requirements, an electrical signal will be transmitted to the telescopic pole 3 and the warning light 7 to initiate the fire extinguishing procedure. Through the dual monitoring of the smoke sensor 5 and the fire source monitoring 6, a fire prevention function is achieved.
