[0024] As a preferred solution of the present invention, any of the above-mentioned intelligent safety warning devices for hazardous chemical warehouses is used, which is characterized by comprising the following steps:

[0025] S1. When the combustible gas detector senses that an object is burning, the control unit in the combustible gas detector will control the first motor and the second transmission sleeve to start with electrical direction feedback. The second transmission sleeve will immediately transmit the fire extinguishing dust to the foam fire extinguishing device. The dust will be transmitted to the two first transmission tubes again through the foam fire extinguishing device. The first transmission tube on the left will immediately transmit the dust to the retractable tube. After the retractable tube transmits the dust to the first transmission sleeve, the three nozzle tubes fixed at the front end of the first transmission sleeve will immediately discharge the dust, and then extinguish the fire. When the first motor is started, the first motor The output shaft will immediately drive the lead screw to rotate, and the lead screw will drive the first nut to move when rotating, and then the first nut will synchronously drive the first transmission sleeve to move, so that the first transmission sleeve slides on the circumferential surface of the two limit rods. The two limit rods will limit the first transmission sleeve to make the first transmission sleeve more stable when moving, and the moving angle of the first transmission sleeve is determined according to the information detected by the smart camera fixed at the front end of the first transmission sleeve. At the same time, personnel can use the external display device to observe the fire source monitored by the smart camera from the first perspective and observe the status of automatic cleaning of the device.

[0026] S2. Through the cooperation of the components in the automatic cleaning mechanism, the specific height can be automatically adjusted to deal with the fire source, and the spray component will spray the fire source from a high place, which can quickly cover and isolate the fire source. The fire source situation observed by the smart camera, the smart controller will automatically control the start of the second motor, and the output shaft of the second motor will immediately drive the smart camera to rotate in three of the second connecting sleeves. The adjustment rod will drive the three spray nozzles on the surface to make small adjustments, so that when the angles of the three spray nozzles are adjusted, the fixed nozzles at the front of the three spray nozzles will immediately spray the fire source. Personnel can connect all monitoring equipment to the cloud server through the Internet of Things technology to achieve remote monitoring and big data analysis, so that managers can check the warehouse status at any time and respond in time. The cloud platform can also optimize the early warning model according to historical data to improve the early warning efficiency. The air filter device fixed at the bottom of the intelligent safety warning device can effectively curb the spread of leakage, reduce environmental pollution and the risk of direct contact between personnel, which not only reduces the dependence on manual intervention, but also significantly shortens the emergency response time and reduces the manpower and time costs of accident handling.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. In this solution, when the combustible gas detector senses an abnormal increase in the concentration of combustible gas in the environment, indicating that the object may be in the initial combustion state, its built-in control unit responds quickly and sends an electrical signal to the first motor and the foam fire extinguishing device to start the command. The foam fire extinguishing device is then activated to transport the stored fire extinguishing dust to the second transmission sleeve, and then distribute it through the two first transmission tubes. The first transmission tube on the left guides the mixture to the contraction tube, and then enters the first transmission sleeve, and finally is ejected by the three nozzle tubes at the front end, directly acting on the fire source to achieve rapid fire extinguishing. At the same time, the first motor drives the screw to rotate, and the screw will drive the first nut to move when rotating, ensuring that the first transmission sleeve moves stably and is accurately positioned. The moving angle is determined according to the on-site fire information captured by the smart camera, and the operator can display it through the external display The screen monitors the fire source in real time, and the automatic cleaning mechanism intervenes further to carry out precise strikes on the fire source through intelligent height adjustment. The spray component sprays the fire extinguishing medium from a high position to quickly cover and isolate the fire source to prevent the fire from spreading. The smart camera continues to monitor, and the captured image information is analyzed by the intelligent controller. According to the changes in the fire situation, the second motor is automatically controlled to rotate, driving the smart camera to adjust the viewing angle in the three second connecting sleeves. The adjustment rod fine-tunes the direction of the three spray nozzles to ensure that the fire extinguishing medium is sprayed more accurately to the fire source. Through the Internet of Things technology, all monitoring and control equipment data are uploaded to the cloud server to achieve remote monitoring, big data analysis and early warning model optimization, and enhance prevention capabilities. In addition, the air filter device continues to operate at the bottom of the intelligent safety warning device to effectively prevent the leakage of harmful gases and protect the environment and personnel safety.

[0029] 2. In this solution, efficient and rapid fire extinguishing response and precise positioning: the system integrates combustible gas detection and immediate response mechanism. Once the abnormal concentration of combustible gas is detected, the foam fire extinguishing device is immediately activated, and the first transmission sleeve is stably and accurately moved and positioned through a precise mechanical transmission structure (such as the cooperation between the first motor-driven lead screw and the first nut). This not only shortens the response time, but also ensures that the fire extinguishing medium can directly and accurately act on the fire source, realizes rapid control and extinguishing of the fire, and effectively prevents the spread of the fire. Intelligent monitoring and dynamic adaptability: the system's built-in intelligent camera can not only capture the fire situation in real time for operators to monitor, but also analyze video information through the intelligent controller, automatically adjust the viewing angle of the intelligent camera controlled by the second motor and the direction of the spray nozzle guided by the adjustment rod, and ensure that the accuracy of the fire extinguishing medium spraying is dynamically optimized as the fire changes. This intelligent fire management method greatly improves the efficiency and flexibility of fire extinguishing and adapts to complex and changeable fire scenes.

[0030] 3. In this solution, remote management and environmental safety assurance are integrated: through the Internet of Things technology, all monitoring and control data of the system can be uploaded to the cloud server in real time, realizing remote monitoring of the fire extinguishing process, big data analysis and continuous optimization of the early warning model, providing strong technical support for fire prevention. At the same time, the effective operation of the air filtration device prevents the leakage of harmful gases, protects the site and surrounding environment from secondary pollution, and ensures personnel safety and environmental protection.
