[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0036] The terms "first", "second", etc. in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0037] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The present application provides an automatic positioning fire extinguishing system that can respond quickly and extinguish fires accurately, thereby improving fire extinguishing efficiency and reducing fire losses. Figure 1 As shown, Figure 1 A structural schematic diagram of an embodiment of an automatic positioning fire extinguishing system provided in the present application includes a fire extinguishing component, a detection component and a control unit.

[0039] The fire extinguishing component includes a fire extinguishing nozzle, an automatic steering mechanism and an electromagnetic valve; the fire extinguishing agent is sprayed based on the fire extinguishing nozzle; the spraying direction of the fire extinguishing nozzle is adjusted based on the automatic steering mechanism; and the spraying state of the fire extinguishing nozzle is adjusted based on the electromagnetic valve.

[0040] The fire sprinkler is designed with a specific spray pattern to evenly distribute the fire extinguishing agent to a designated area. The sprinkler is equipped with an automatic steering mechanism inside or outside the sprinkler, which allows the sprinkler to change direction as needed.

[0041] The automatic steering mechanism is composed of a motor, a gear system or a hydraulic drive device, etc. It can receive instructions from the control unit and accurately adjust the angle and position of the nozzle to ensure that the fire extinguishing agent can directly act on the high temperature point.

[0042] The solenoid valve is installed on the pipeline between the fire sprinkler and the agent storage container to control the flow of the agent. When receiving an open signal, the solenoid valve opens to allow the agent to pass; when receiving a close signal, the solenoid valve closes to stop the supply of the agent.

[0043] It should be clarified that the automatic positioning fire extinguishing system includes multiple fire extinguishing components to improve the fire extinguishing efficiency. For example, the automatic positioning fire extinguishing system includes three fire extinguishing components, which are evenly distributed in the automatic positioning fire extinguishing system. In other embodiments, the number of fire extinguishing components may also take other values, and there is no limitation on this.

[0044] The detection component includes an infrared temperature detector, which is used to detect the specific location and high temperature state of high-temperature points. It adopts a non-contact measurement method, which can quickly and accurately detect the temperature distribution in various parts of the cabin and identify areas with abnormally high temperatures (i.e. possible fire points). Once a high-temperature point is found, the detector will immediately send its location information to the control unit.

[0045] The control unit obtains the specific location and high temperature status of the high temperature point and then adjusts the working status of the automatic steering mechanism and the solenoid valve to achieve precise cooling or fire extinguishing; the control unit can collect data from the infrared temperature detector in real time, analyze and determine whether there is a fire risk.

[0046] If a high temperature spot is confirmed, the control unit will calculate the best fire extinguishing strategy based on the preset algorithm; the control unit sends a steering command to the automatic steering mechanism to direct the fire extinguishing nozzle to the high temperature spot; at the same time, it will also send an opening signal to the solenoid valve to start the spraying of the fire extinguishing agent. During the whole process, the control unit continuously monitors environmental changes and adjusts the direction of the nozzle or the flow of the agent when necessary to ensure the fire extinguishing effect.

[0047] The fire extinguishing steps of the automatic positioning fire extinguishing system are described in detail below:

[0048] In the initial state, the fire extinguishing nozzle is in the default position, the automatic steering mechanism remains stationary, and the solenoid valve is closed to ensure that the fire extinguishing agent does not flow out accidentally.

[0049] Infrared temperature detectors continuously monitor temperature changes in the energy storage container. Once an abnormal temperature rise is detected in a certain area, the detector will immediately send an alarm signal to the control unit and provide the specific coordinates and temperature data of the hot spot.

[0050] After receiving the high temperature point information, the control unit will analyze and calculate the best fire extinguishing path. It will send instructions to the automatic steering mechanism according to the location of the high temperature point to adjust the direction of the fire extinguishing nozzle so that the nozzle points accurately to the high temperature point.

[0051] When the fire sprinkler is successfully aimed at the high temperature point, the control unit will send an opening command to the solenoid valve. The solenoid valve responds to the command and opens, allowing the fire extinguishing agent to flow from the storage container through the pipeline to the fire sprinkler and be sprayed out by the sprinkler to directly act on the high temperature point or flame.

[0052] During the spraying process, the infrared temperature detector continues to monitor the temperature changes of the high-temperature points and feeds back to the control unit in real time. If the temperature drops to a safe range, the control unit will determine that the fire is extinguished successfully and send a closing command to the solenoid valve to stop spraying; if the temperature does not drop significantly or new high-temperature points appear, the control unit will continue to command the fire-extinguishing sprinkler to spray until all fire hazards are eliminated.

[0053] After the fire is extinguished, the system will automatically reset to its initial state, the automatic steering mechanism will restore the fire sprinkler to the default position, and the solenoid valve will close to prevent any remaining agent from leaking.

[0054] In summary, the automatic positioning fire extinguishing system of this embodiment includes: a fire extinguishing component, a detection component and a control unit; the fire extinguishing component includes a fire extinguishing nozzle, an automatic steering mechanism and a solenoid valve; the fire extinguishing agent is sprayed based on the fire extinguishing nozzle; the spraying direction of the fire extinguishing nozzle is adjusted based on the automatic steering mechanism; the spraying state of the fire extinguishing nozzle is adjusted based on the solenoid valve; the detection component includes an infrared temperature detector, which is used to detect the specific position and high temperature state of the high temperature point; the control unit obtains the specific position and high temperature state of the high temperature point and then adjusts the working state of the automatic steering mechanism and the solenoid valve to achieve precise cooling or fire extinguishing. By providing an automatic positioning fire extinguishing system that can respond quickly and extinguish fires accurately, the fire extinguishing efficiency is improved and the fire loss is reduced.

[0055] like Figure 2 As shown, Figure 2 This is a structural schematic diagram of an embodiment of a detection component provided in the present application. The detection component also includes a combustible gas detector, a temperature detector and a smoke detector.

[0056] The combustible gas detector detects the combustible gas concentration in the fire extinguishing system and sends it to the control unit. The control unit obtains the combustible gas concentration and compares it with the concentration threshold. Combustible gases include hydrogen and methane. Different concentration thresholds can be set for different combustible gases. The control unit has preset safety concentration thresholds for different types of combustible gases. When receiving new concentration data, the control unit will immediately compare it with the corresponding threshold.

[0057] If the detected combustible gas concentration is below the threshold, the system maintains normal operation and continues monitoring.

[0058] If the detected concentration reaches or exceeds the threshold, the control unit triggers an alarm mechanism.

[0059] By real-time monitoring of combustible gas concentrations, the system can issue an early warning before a fire or explosion occurs, buying valuable time for timely preventive measures and effectively avoiding accidents. Based on the comparison of concentration thresholds, the system can accurately determine whether there are safety hazards and initiate targeted response measures of the corresponding level, improving the scientificity and effectiveness of prevention and control.

[0060] The temperature detector is used to detect the ambient temperature in the fire extinguishing system and send it to the control unit, which obtains the ambient temperature and compares it with the temperature threshold. The temperature detector (such as the explosion-proof point-type temperature fire detector) continuously detects temperature changes in various areas of the cabin. The detector uses a high-precision temperature sensor that can accurately measure small temperature fluctuations and transmit data to the control unit in real time.

[0061] The temperature detector sends the collected ambient temperature data to the control unit. After receiving the data, the control unit will perform preliminary processing, such as filtering, correction and unit conversion, to ensure the accuracy and consistency of the data.

[0062] The control unit has preset safety temperature thresholds for different areas. When new temperature data is received, the control unit will immediately compare it with the corresponding threshold.

[0063] If the detected ambient temperature is below the threshold, the system maintains normal operation and continues monitoring.

[0064] If the detected temperature reaches or exceeds the threshold, the control unit triggers the alarm mechanism.

[0065] By combining heat detectors with infrared temperature detectors, it is possible to more accurately distinguish whether the increase in ambient temperature is due to normal operation or a potential fire, thereby reducing the possibility of false alarms and improving system reliability.

[0066] Smoke detectors are used to detect the smoke concentration in the fire extinguishing system and send it to the control unit. The control unit obtains the smoke concentration and compares it with the smoke concentration threshold. Smoke detectors (such as explosion-proof point smoke fire detectors) continuously detect the smoke concentration in the cabin air. The smoke detectors send the collected smoke concentration data to the control unit. The control unit has preset safety smoke concentration thresholds for different areas. When receiving new smoke concentration data, the control unit will immediately compare it with the corresponding threshold:

[0067] If the detected smoke concentration is lower than the threshold, the system maintains normal operation and continues monitoring.

[0068] If the detected smoke concentration reaches or exceeds the threshold, the control unit will trigger the alarm mechanism.

[0069] Smoke detectors combined with infrared temperature detectors and heat detectors can more accurately distinguish whether smoke is caused by fire or other reasons (such as dust, steam, etc.), thereby reducing the possibility of false alarms and improving system reliability.

[0070] The automatic positioning fire extinguishing system also includes water fire fighting pipelines; such as Figure 3 As shown, Figure 3 A schematic structural diagram of an embodiment of a water fire fighting pipeline provided in the present application, including a pressure relief port, an exhaust fan and an electric shutter.

[0071] The pressure relief port is based on the pressure difference between the inside and outside of the automatic positioning fire extinguishing system; the pressure relief port can quickly release the excessive pressure in the cabin when the fire extinguishing system is started, preventing the cabin from being deformed or damaged due to excessive pressure. By balancing the pressure difference between the inside and outside, the pressure relief port ensures that the fire extinguishing agent can be more evenly spread to every corner of the cabin, thereby improving the fire extinguishing effect.

[0072] Exhaust fans can discharge combustible gases and smoke; exhaust fans can quickly discharge combustible gases and smoke in the cabin, reducing the risk of explosion and fire spread, especially in the early stages of a fire, timely exhaust can effectively prevent the fire from spreading; exhaust fans can not only remove harmful gases, but also take away heat from the cabin, lower the temperature, and improve the air quality in the cabin.

[0073] The air circulation in the cabin is regulated based on electric shutters; the electric shutters can be opened when needed to introduce fresh air, promote air circulation in the cabin, help cool down and dilute harmful gases, and accelerate the recovery of the cabin environment; the electric shutters can be flexibly opened and closed according to the actual situation in the cabin, which can not only keep the cabin sealed during the fire extinguishing process, but also quickly ventilate after the fire extinguishing, ensuring that the cabin environment returns to normal as soon as possible.

[0074] The combination of pressure relief vents, exhaust fans and electric shutters forms a multi-level safety protection system that can effectively respond to various emergencies and significantly improve the safety performance of energy storage containers. All equipment is centrally managed by a control unit to achieve automated linkage operation without manual intervention, fast response speed and high operational consistency.

[0075] The present application also provides a control method which can be applied to the automatic positioning fire extinguishing system as described in any of the above embodiments, wherein only the infrared temperature sensor alarm includes the following steps:

[0076] Upload fire warning signals and activate sound and light alarms;

[0077] The DC power is cut off, the fire sprinkler is aimed at the high temperature point, and the solenoid valve is opened to spray the fire extinguishing agent.
