Description

Technical Field

[0001] This utility model relates to the field of drone firefighting technology, and more specifically, to a drone-borne fire prevention and extinguishing system. Background Technology

[0002] With the rapid development of drone technology, unmanned cargo transport drones are increasingly used in the logistics industry. These drones are typically equipped with large cargo holds to carry goods; however, the cargo inside the hold may ignite due to vibrations during takeoff, landing, and flight. Therefore, fire prevention and extinguishing technologies for drone cargo holds have become a key research focus. Existing technologies generally adjust the concentration of extinguishing agents in the cargo hold by controlling the time threshold of the fire prevention and extinguishing system to achieve fire prevention and extinguishing objectives. Although this technology meets fire extinguishing requirements to a certain extent, the system contains multiple high-speed and low-speed extinguishing cylinders, which not only increases the drone's payload but also occupies internal cargo space, leading to increased transportation costs and reducing the economic viability of drone transportation.

[0003] Therefore, there is an urgent need for a new type of drone-based fire prevention and suppression system that can reduce system weight and transportation costs while ensuring fire suppression effectiveness, and has the ability to automatically monitor, suppress fires in different areas, and continuously suppress fires, so as to improve the reliability and economy of the system.

[0033] With the rapid development of drone technology, unmanned cargo transport drones are increasingly used in the logistics industry. These drones are typically equipped with large cargo holds to carry goods; however, the cargo inside the hold may ignite due to vibrations during takeoff, landing, and flight. Therefore, fire prevention and extinguishing technologies for drone cargo holds have become a key research focus. Existing technologies generally adjust the concentration of extinguishing agents in the cargo hold by controlling the time threshold of the fire prevention and extinguishing system to achieve fire prevention and extinguishing objectives. Although this technology meets fire extinguishing requirements to a certain extent, the system contains multiple high-speed and low-speed extinguishing cylinders, which not only increases the drone's payload but also occupies internal cargo space, leading to increased transportation costs and reducing the economic viability of drone transportation.

[0034] Therefore, there is an urgent need for a new type of drone-based fire prevention and suppression system that can reduce system weight and transportation costs while ensuring fire suppression effectiveness, and has the ability to automatically monitor, suppress fires in different areas, and continuously suppress fires, so as to improve the reliability and economy of the system.

[0035] Please refer to Figures 1-2 This embodiment provides an unmanned aerial vehicle (UAV)-borne fire prevention and extinguishing system, which can effectively improve the technical problems mentioned above, and can reduce system weight and transportation costs while ensuring fire extinguishing effect.

[0036] Please refer to Figures 1-2 This embodiment provides an airborne fire prevention and extinguishing system for unmanned aerial vehicles (UAVs), including a UAV cargo compartment, a storage module 10, a delivery module 20, a fire extinguishing module 30, a monitoring module 40, and a control module 50. The storage module 10 is used to store fire extinguishing agents. The delivery module 20 is connected to the storage module 10, and the fire extinguishing module 30 is connected to the delivery module 20. The monitoring module 40 is installed in the UAV cargo compartment and is used to monitor fire information in the cargo compartment. The control module 50 is connected to the storage module 10, the delivery module 20, the fire extinguishing module 30, and the monitoring module 40.

[0037] In this embodiment, there are multiple monitoring modules 40, which are installed in multiple areas within the cargo hold. These multiple monitoring modules 40 are used to monitor fire information in these multiple areas of the cargo hold. Specifically, the multiple monitoring modules 40 can be installed in different areas of the cargo hold to monitor fire information in each of those areas.

[0038] Specifically, the monitoring module 40 includes a temperature relay 41 and a smoke detector 42, both of which are connected to the control module 50. The temperature relay 41 activates under high-temperature conditions and sends a fire alarm signal for the area to the control module 50. The smoke detector 42 monitors the smoke concentration in the cargo hold area and sends a fire alarm signal for the area to the control module 50 if the smoke concentration is too high.

[0039] In this embodiment, the storage module 10 includes a flushing connector 11, a flushing switch 12, and a fire extinguishing bottle 13. The flushing connector 11 and the flushing switch 12 are connected. The flushing connector 11 is used to connect to an external flushing device, and the flushing switch 12 is connected to the control module 50. The fire extinguishing bottle 13 is connected to the flushing connector 11. The flushing switch 12 is located on the connecting pipe between the fire extinguishing bottle 13 and the flushing connector 11. When activated, the flushing switch 12 allows the external flushing device to inject extinguishing liquid into the fire extinguishing bottle 13. The fire extinguishing bottle 13 can be filled with extinguishing liquid and can quickly release the extinguishing agent in the event of a fire in the cargo hold.

[0040] Furthermore, the storage module 10 also includes a pressure sensor 14, which is connected to the fire extinguishing bottle 13 and can detect the pressure of the extinguishing agent inside the fire extinguishing bottle 13. When the pressure inside the fire extinguishing bottle 13 is too low, the pressure sensor 14 outputs a pressurization signal to the control module 50 to prompt maintenance personnel to add extinguishing agent.

[0041] Furthermore, the storage module 10 also includes a pressure reducing valve 25, which is connected to the fire extinguishing bottle 13 and can adjust the pressure of the fire extinguishing bottle 13 to the system's rated pressure.

[0042] It should be noted that the delivery module 20 includes a fire extinguishing pipeline 21 and a first solenoid valve 22. The fire extinguishing pipeline 21 is connected to both the storage module 10 and the fire extinguishing module 30. The first solenoid valve 22 is mounted on the fire extinguishing pipeline 21 and is connected to the control module 50. The fire extinguishing pipeline 21 can extend to various areas within the cargo hold, thereby delivering fire extinguishing agent to these areas.

[0043] Furthermore, the delivery module 20 also includes a flow sensor 23, which is installed in the fire extinguishing pipeline 21 and is connected to the control module 50.

[0044] Preferably, the delivery module 20 further includes a throttle valve 24, which is disposed in the fire extinguishing pipeline 21 and connected to the control module 50.

[0045] Furthermore, the delivery module 20 also includes a third solenoid valve 26, which is separately installed on another circuit between the fire extinguishing bottle 13 and the fire extinguishing pipeline 21. The third solenoid valve 26 is in the normally open state, so that the extinguishing agent in the fire extinguishing bottle 13 can be slowly and continuously output to the fire extinguishing pipeline 21 to prevent the fire from recurring in the cargo hold.

[0046] In this embodiment, there are multiple fire extinguishing modules 30, which are distributed and installed in multiple areas within the cargo hold. Each fire extinguishing module 30 can individually extinguish fires in its respective area. Specifically, each fire extinguishing module 30 is a fire extinguishing ring 32. Each fire extinguishing module 30 is equipped with a second solenoid valve 31, which allows for individual control of each module, enabling either individual or collective fire extinguishing, thus providing greater flexibility and convenience.

[0047] During operation, the entire system can automatically perform fire prevention and firefighting tasks via a control computer. When a fire occurs in an area of ​​the cargo hold, the temperature relay 41 and smoke detector 42 send a fire alarm signal to the control module 50. The control module 50 opens the first solenoid valve 22, quickly releasing the extinguishing agent into the fire extinguishing pipeline 21. Based on the location of the fire, it opens the second solenoid valve 31. After the second solenoid valve 31 opens, the extinguishing agent is released into the cargo hold through the fire extinguishing ring 32, and the fire is quickly contained. After a fire occurs, the control module 50 sends a fire warning to the ground station, allowing ground station operators to promptly take emergency measures against the UAV. To prevent the fire from recurring, the control module 50 continuously opens the third solenoid valve 26 and the throttle valve 24, allowing the extinguishing agent to be released slowly.

[0048] In summary, this utility model embodiment provides an airborne fire prevention and extinguishing system for unmanned aerial vehicles (UAVs). The airborne fire prevention and extinguishing system includes a UAV cargo compartment, a storage module 10, a delivery module 20, a fire extinguishing module 30, a monitoring module 40, and a control module 50. The storage module 10 is used to store fire extinguishing agents. The delivery module 20 is connected to the storage module 10, the fire extinguishing module 30 is connected to the delivery module 20, the monitoring module 40 is installed in the UAV cargo compartment to monitor fire information in the cargo compartment, and the control module 50 is connected to the storage module 10, the delivery module 20, the fire extinguishing module 30, and the monitoring module 40. In use, by adopting a single storage module 10 instead of the configuration of multiple fire extinguishing bottles 13 in the traditional system, the overall weight of the system is significantly reduced, cargo space is saved, and the transportation efficiency and economy of the UAV are improved. Furthermore, the delivery module 20 and the control module 50 work together to control the release rate of the extinguishing agent according to the urgency of the fire. This allows for both rapid fire extinguishing and slow release of the extinguishing agent after the fire is extinguished to prevent reignition, thus improving the reliability and safety of fire extinguishing. The monitoring module 40 is deployed in multiple key areas inside the cargo hold to collect fire-related parameters such as temperature and smoke concentration in real time, promptly detect potential fire hazards, and feed back fire alarm information to the control module 50 for rapid early warning and response. The entire system operates fully automatically through the control module 50, completing fire monitoring, judgment, and fire extinguishing operations without human intervention. At the same time, it can transmit fire alarm information to ground station equipment in real time, facilitating ground operators to grasp the fire status and carry out emergency response.
