[0032] The present disclosure is described below through several specific embodiments. In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits the detailed description of known functions and known components. Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a heavy-load UAV for firefighting and rescue, comprising:

[0033] A cabin 1, wherein the cabin 1 is filled with fire extinguishing substances and light gas, and a plurality of nozzles 11 are provided on the cabin 1, wherein the nozzles 11 are configured to enable the cabin 1 to release the fire extinguishing substances;

[0034] The power system 2 includes a motion system 21 and a frame 22, wherein the motion system 21 is mounted on the frame 22, and the UAV is fixedly connected to the cabin 1 via the frame 22;

[0035] A gas tank (not shown), which is arranged inside the cabin 1, and on which an electric valve is arranged, wherein the electric valve is configured to enable the gas tank to release the light gas;

[0036] A safety belt 3 is fixed below the frame 22;

[0037] An air pressure sensor (not shown) for detecting the air pressure in the cabin 1; and

[0038] A controller, respectively connected to the power system 2, the nozzle 11, the gas tank and the air pressure sensor for communication;

[0039] The controller is configured as follows: when the nozzle 11 is closed, if the air pressure value detected by the air pressure sensor is less than a first preset threshold value, the electric valve is opened until the air pressure value is greater than or equal to the first preset threshold value; when the nozzle 11 is opened, if the air pressure value detected by the air pressure sensor is less than a second preset threshold value, the electric valve is opened so that the air pressure value is greater than the second preset threshold value.

[0040] The embodiment of the present invention provides a cabin 1 storing light gas and fire extinguishing materials on the drone, and a gas tank is provided in the cabin 1. On the one hand, when the drone reaches the fire point, the nozzle 11 on the cabin 1 can be opened to release the fire extinguishing materials to extinguish the fire, and at the same time, the gas is released by the gas tank to provide release pressure. On the other hand, the light gas in the cabin 1 can provide the drone with rising buoyancy, increasing the load-bearing capacity of the drone. After the drone provided by the present invention releases the fire extinguishing materials, its own load-bearing capacity is further improved, and at the same time, the safety belt 3 provided can be used to rescue people trapped in the fire scene.

[0041] Preferably, the control system includes a remote control function and a wireless communication module to achieve real-time data transmission and control command reception between the drone and the ground control center. The control system can automatically avoid obstacles and fly stably in complex environments, ensuring the successful completion of the mission through efficient obstacle detection and avoidance technology.

[0042] In addition, by controlling the air pressure in the cabin 1 according to the air pressure value of the air pressure sensor through the controller, sufficient pressure can be provided for spraying and releasing the fire extinguishing material, while preventing the cabin 1 from being deformed due to low pressure and causing structural damage.

[0043] In some embodiments, an equipment area is also included: used to install various necessary equipment, including high-definition cameras, thermal imaging cameras, gas sensors, and communication devices, etc. These devices can monitor the fire scene in real time, detect fire sources and hot spots, and transmit data back to the ground control center to help firefighters make quick and accurate decisions.

[0044] In some embodiments, the safety belt 3 is made of high-strength heat-resistant material and can withstand high temperatures and other adverse conditions in a fire scene. The sling device includes a quick lock and adjustment mechanism to ensure that the trapped person can be quickly and safely fixed and rescued. The safety belt 3 is arranged below the power system 2 through a fixing belt 31.

[0045] In some embodiments, the cabin 1 is in the shape of a ring, and the power system 2 is disposed in the center of the ring.

[0047] In some embodiments, the cabin 1 has a first cavity 12 and a second cavity 13 divided by an elastic diaphragm, and the first cavity 12 is located below the second cavity 13. Figure 2 or the first cavity 12 is located outside the second cavity 13, as shown; Figure 3 shown.

[0048] The first cavity 12 is filled with the light gas and the fire extinguishing substance, and the second cavity 13 is filled with the light gas.

[0049] Dividing the cabin 1 into the first cavity 12 and the second cavity 13 is beneficial to ensuring the continuity of the output of the fire extinguishing material, and avoiding the reduction in the density of the subsequent fire extinguishing material release due to the increase and decrease of the fire extinguishing material and the light gas.

[0050] In some embodiments, the gas tank is located in the second cavity 13 , and the nozzle 11 is connected to the first cavity 12 .

[0051] In some embodiments, the motion system 21 includes a plurality of rotors 212 and a motion drive module 211 connected to the rotors 212. The motion drive module 211 is disposed at the bottom of the frame 22. The frame 22 is provided with a protection hole corresponding to the rotors 212, and the rotors 212 are located in the protection hole. The rotors 212 are made of lightweight, high-strength materials, such as carbon fiber or composite materials, to ensure higher thrust and lower energy consumption. The rotors 212 are installed in these protection holes, which can not only provide sufficient air flow space, but also protect the rotors 212 from impact or interference from debris in the external environment. This design ensures that the rotors 212 can work efficiently and stably during the operation of the platform.

[0053] In some embodiments, the fire extinguishing substance includes one of water, foam, halogenated fire extinguishing agent or dry powder fire extinguishing agent, and the light gas includes helium.

[0054] In some embodiments, the cabin 1 and the motion system 21 are both covered with high temperature resistant materials. The overall material of the drone is resistant to high temperature and corrosion, and can work normally in a high temperature fire environment. The material includes polyimide aerogel and glass fiber shell, and is coated with a super reflective aluminum layer to reflect heat and protect the internal precision electronic components.

[0055] In some embodiments, a camera is also included, and the camera is arranged at the lower end of the power system 2.

[0056] The drone is equipped with advanced sensor technology, including thermal imaging cameras and gas detection sensors, which can detect hot spots, smoke and harmful gases in the fire scene in real time, provide key on-site information, and assist firefighters in effective firefighting and rescue. The thermal imaging camera can penetrate the smoke and provide clear images of the fire scene, while the gas detection sensor can identify toxic and harmful gases that may be present in the fire scene, providing firefighters with timely warning information.
