[0002] At present, the fire problem of high-rise buildings has become the focus of attention in my country and even the world. Due to the increasing complexity and height of high-rise building design, the risk of fire is also increasing. Traditional fire-fighting equipment is often difficult to extinguish fires quickly, efficiently and comprehensively when facing high-rise fires. Therefore, it is particularly important to design a fire-fighting equipment suitable for high-rise buildings.

[0003] Related prior art: Traditional ceiling-mounted dry powder automatic fire extinguishing system.

[0004] This system usually consists of a central fire extinguishing material storage warehouse, a delivery pipeline connected to the warehouse, and multiple injection nozzles distributed in specific areas. When a fire is detected, the system automatically releases dry powder fire extinguishing material, which is delivered to the injection nozzles through the pipeline to extinguish the fire. This system contains basic flame or smoke detectors to trigger the fire extinguishing process.

[0005] Through the above analysis, the problems and defects of the prior art are as follows:

[0006] 1. Response time: Traditional systems are usually activated only after detecting flames or smoke, which leads to a delay in responding in the initial stage of a fire, thus allowing the fire to spread.

[0007] 2. Positioning accuracy: Traditional systems cannot accurately locate the fire source, resulting in the fire extinguishing base material not being concentrated at the fire source, reducing the fire extinguishing efficiency.

[0008] 3. Flexibility and adaptability: These systems are usually static and cannot dynamically adjust firefighting strategies based on environmental changes or fire conditions.

[0009] 4. Maintenance and detection complexity: Traditional systems require regular maintenance and inspection to ensure that they can work properly in emergency situations, which increases maintenance costs and complexity.

[0010] 5. Firefighting efficiency: Due to the lack of intelligent control and refined management, traditional systems are not as efficient in firefighting as systems based on advanced technologies. Utility Model Content

[0036] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Figure 1 , Figure 2 and Figure 3As shown, an embodiment of the utility model provides a top-mounted fire-fighting dry powder fire extinguisher, which includes a high-pressure gas tank 1, which is connected to a first pipe 2, and a thickened fixing strip 10 is sleeved on the high-pressure gas tank 1; the other end of the first pipe 2 is connected to a base material bin 4, and a valve 3 is installed on the outer wall of the first pipe 2; the other end of the base material bin 4 is connected to a second pipe 5, and a first hanging bolt 11 is threadedly connected to the base material bin 4; the other end of the second pipe 5 is connected to a detector 6; the detector 6 is connected to a first injection port 7, a second injection port 8 and a third injection port 9, and the second hanging bolt 12 is threadedly connected to the detector 6.

[0037] The four first hanging bolts 11 are threadedly connected to the four corners of the base material bin 4 and are used to hang or fix the base material bin 4 . The four second hanging bolts 12 are threadedly connected to the four corners of the detector 6 and are used to hang or fix the detector 6 .

[0038] like Figure 5 As shown, the components provided in the embodiment of the utility model and their detailed connection relationship and position relationship are as follows:

[0039] Air detection circulation hole 5-1: arranged near or inside the fire extinguishing base material transportation pipeline 5-3, used to allow air circulation for air quality detection.

[0040] Fire extinguishing base material transport pipeline fixing module 5-2: a structural component used to fix the fire extinguishing base material transport pipeline 5-3. Installed at a key position of the top-mounted fire-fighting dry powder fire extinguisher and connected to the fire extinguishing base material bin.

[0041] Fire extinguishing base material transport pipeline 5-3: connects the high-pressure gas tank 1 and the injection port, and is used to transport the fire extinguishing base material from the high-pressure gas tank 1 to multiple injection ports; the injection ports include a first injection port 7, a second injection port 8, and a third injection port 9, which are used to perform fire extinguishing operations at different locations. The fire extinguishing base material transport pipeline 5-3 passes through or is fixed to the fire extinguishing base material transport pipeline fixing module 5-2. The fire extinguishing base material transport pipeline 5-3 is further connected to a fire extinguishing base material bin, and multiple valves are provided inside the fire extinguishing base material transport pipeline 5-3 to control the transportation of the fire extinguishing base material.

[0042] Air detection module 5-4: installed near the air detection circulation hole 5-1, used to detect the quality of air passing through the circulation hole. The air detection module 5-4 is connected to the detector 6 to provide real-time feedback of the fire extinguishing operation and adjust the fire extinguishing strategy according to the feedback.

[0043] Fixed module mounting screw 5-5: The fixed module mounting screw 5-5 is a hanging bolt or a fixing strip, which is used to flexibly install the top-mounted fire-fighting dry powder fire extinguisher in various environments and occasions. It is used to fix the fire-extinguishing base material transport pipeline fixing module 5-2 at a specified position and to fix it on the frame or other structure of the top-mounted fire-fighting dry powder fire extinguisher.

[0044] Each part of a ceiling-mounted dry powder fire extinguisher plays an important role. The flow of the extinguishing base, the detection of air quality, and the fixation and stability of the system are all key factors to ensure the efficient and safe operation of the ceiling-mounted dry powder fire extinguisher.

[0045] The working principle of the utility model is: when the utility model is used, the compressed gas is first filled into the high-pressure gas cylinder 1. The high-pressure gas cylinder 1 injects the gas from the first pipe 2 into the base material bin 4. A valve 3 is installed on the outer wall of the first pipe 2. The valve 3 can close the first pipe 2 to prevent the gas from entering the base material bin 4. The inside of the base material bin 4 is filled with baking soda, ammonium carbonate, and ammonium salts of phosphoric acid. The base material bin 4 is connected to a second pipe 5. The diameter of the second pipe 5 is larger than that of the first pipe 2 to prevent the pipe from being blocked during the fire extinguishing operation. The second pipe 5 is connected to a detector 6, which is used to detect the air quality and smoke concentration. When the threshold is reached, the fire extinguishing operation is started and connected to the host controller. The detector 6 is connected to a first injection port 7 and a second injection port 8. When the detector 6 detects thick smoke in the air, the detector 6 sprays baking soda, ammonium carbonate, and ammonium salts of phosphoric acid from the first injection port 7 and the second injection port 8 into a mist to extinguish the flame. The specific process of the fire extinguishing operation can be seen. Figure 4 The first pipeline 2 contains highly compressed gas 4-1 released from a high-pressure gas tank, the second pipeline 5 contains compressed gas 4-2 with fire extinguishing base material in the base material bin, and fire extinguishing gas 4-3 ejected from the first and second ejection ports.
