A central control module is arranged on the main beam 1, and the central control module is connected to the smoke sensor and the thermal detector through a communication unit, and the central control module can send warning information to the management center through the communication unit when the smoke sensor or the thermal detector sends a fire warning signal, so that the staff can quickly intervene to carry out on-site fire fighting.

[0038] As a preferred embodiment, the fire extinguishing mechanism 3 includes: an upper frame 31, two support rods 32 are vertically arranged on the left and right sides of the upper frame 31, the support rods 32 are slidably connected to the upper frame 31, and an assembly seat 33 is fixed to the lower end surface of the support rod 32.

[0042] In this embodiment, each of the fire extinguishing agent storage tanks 24 stores different types of fire extinguishing agents, including but not limited to water-based fire extinguishing agents, dry powder fire extinguishing agents, and foam fire extinguishing agents. Each fire extinguishing agent has its specific advantages and provides effective response measures for different types of fires.

[0043] In this embodiment, a monitoring module is provided on the main beam 1. The monitoring module obtains the storage image inside the factory area in real time through a high-definition camera. The central control module wirelessly transmits the obtained storage image data to the image processing server cloud, so that the storage image is pre-processed by noise filtering and contrast adjustment to achieve image quality optimization. The central control module analyzes and identifies the optimized image through a preset model, thereby obtaining storage-related feature data, and analyzes the storage fire characteristics through database retrieval, thereby matching the best fire extinguishing agent;

[0044] The central control module instructs the spraying device 4 in the fire extinguishing mechanism to take preset actions to extinguish the fire based on the characteristics of the storage fire. That is, since the preset action is based on the fire characteristics, the spraying device 4 can be started quickly and accurately to deliver the fire extinguishing agent directly to the fire source, thereby improving the fire extinguishing efficiency and reducing the waste of fire extinguishing agent.

A nozzle 5 is fixed below the main body 41, and the lower end of the powder tube 42 is vertically fixed in the middle of the nozzle 5. A nozzle 51 is fixed at the center of the nozzle 5, and the nozzle 51 is connected to the powder tube 42; that is, the powder tube is only used to spray the dry powder fire extinguishing agent to avoid cross mixing of the fire extinguishing agent. Mixing the water-containing type of fire extinguishing agent with the dry powder fire extinguishing agent will produce unforeseen consequences, including reducing the fire extinguishing effect, generating harmful substances or even causing pipeline blockage, so the special nature of the powder tube avoids this risk;

[0046] The main body 41 is provided with a liquid pipe, and the liquid pipe 43 is provided with an inner channel 44 and an outer channel 45 of a concentric structure, and the inner channel 44 and the outer channel 45 are both used to transport other types of fire extinguishing agents in the fire extinguishing agent transport device; that is, other types of fire extinguishing agents (containing water or gas) can be sprayed through the inner channel and the outer channel at the same time;

[0047] The middle part of the nozzle 5 is provided with a rapid jet channel 52, and a circulation cavity 53 is provided inside the nozzle 5 at the periphery of the rapid jet channel 52. A plurality of diffuse jet channels are obliquely distributed below the circulation cavity 53 in the nozzle 5; that is, other types of fire extinguishing agents (water-containing or gas-containing) can be sprayed out through diffuse jet channels or rapid jet channels in the nozzle, wherein the diffuse jet channel design allows the fire extinguishing agent to diffuse in the air to form a uniform coverage surface, which is very efficient for fires that require large-area cooling or covering to isolate oxygen (such as wood and paper burning); it can quickly reduce the temperature of the fire scene and prevent the fire from spreading. The rapid jet channel can concentrate the power of the fire extinguishing agent to form a strong water flow or air flow, directly impacting the center of the fire source or the core combustion area, and is suitable for occasions where it is necessary to quickly penetrate the flame to reach the surface of the burning object, such as electrical equipment, grease fire, etc. Therefore, the appropriate spray mode is selected according to the different fire characteristics;

[0048] The main body 41 is provided with a dispensing pipe 6, which is used to transfer the liquid in the liquid pipe 43 to the of The inner channel 44 and the outer channel 45 are connected to the diffuse flow channel and the rapid flow channel 52 in the nozzle 5 correspondingly.

[0049] In this embodiment, the dispensing pipe 6 is rotatably connected in the main body 41, and a sealing pipe 46 is fixed in the main body 41. The sealing pipe 46 is provided with a first channel 47 and a second channel 48. The first channel 47 is sealed and connected to the rapid flow channel 52, and the second channel 48 is sealed and connected to the annular flow chamber 53.

[0050] A first flow channel 61 and a second flow channel 62 are provided in the dispensing pipe 6. The upper ends of the first flow channel 61 and the second flow channel 62 in the dispensing pipe 6 are in a concentric structure, and the first flow channel 61 is located outside the second flow channel 62. The first flow channel 61 is connected to the outer channel 45 in the liquid pipe 43, and the second flow channel 62 is connected to the inner channel 44 in the liquid pipe 43. The lower ends of the first flow channel 61 and the second flow channel 62 are in a left and right branch structure, so that the first flow channel 61 is connected to the first channel 47 or the second channel 48 during the rotation adjustment of the dispensing pipe 6.

[0051] In this embodiment, the inner channel 44 in the liquid pipe 43 pumps other types of fire extinguishing agents horizontally, so that when the dispensing pipe is rotated and adjusted, other types of fire extinguishing agents are sprayed out at a constant pressure through the diffuser or jet flow channel in the nozzle 5 to form the main fire extinguishing power source; and other types of fire extinguishing agents that can be provided in pulses in the outer channel of the liquid pipe 43 form a second fire extinguishing power source at this time, further improving the fire extinguishing effect. For example, the main fire extinguishing power source (fire extinguishing agent sprayed at a constant pressure) provides a continuous and stable supply of fire extinguishing agent, quickly covers or directly impacts the fire source, and controls the development of the fire. The second fire extinguishing power source (pulse spraying) breaks the flame structure through intermittent, high-intensity spraying, further accelerating the fire extinguishing process. The two work together to significantly improve the fire extinguishing efficiency. At the same time, the dual power source design can flexibly respond to different combustion stages and changes in fire intensity, especially for deep or concealed fire points. The pulse spraying can penetrate smoke and obstacles and reach deeper fire sources.

[0052] In this embodiment, the nozzle 5 is provided with a plurality of flow branches connected to the rapid flow channel 52, and each of the flow branches is rotatably connected to a nozzle 54.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
