Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to an aircraft for fire-fighting. Background Art

[0002] Firefighting operations primarily involve rescuing personnel at the fire scene, saving important facilities and equipment, and cultural relics, safeguarding and rescuing valuable property, and extinguishing fires. The goal is to minimize the damage caused by fires, and reduce casualties and property losses. In wartime, this is under the unified command of civil air defense headquarters at all levels, with professional firefighting forces as the backbone, mobilizing professional firefighting brigades from enterprises, institutions, and townships, volunteer teams, and the general public. Firefighting operations primarily include: ① Assessing the fire situation and damage, understanding the terrain and wind direction at the fire scene, the structure of the burning building, its entrances and exits, and the situation of trapped personnel. ② Implementing on-the-spot command, organizing forces to rapidly reach the fire scene, selecting firefighting agents and equipment based on the nature of the fire, and employing appropriate firefighting tactics tailored to the fire scene. Key methods include preventing fire, establishing firebreaks, blocking fire routes, extinguishing residual fires, and securing the fire scene. ③ Promptly rescue trapped personnel and evacuate injured personnel. ④ Promptly remove or isolate hazardous materials near the fire scene to prevent secondary disasters. Firefighting will be carried out using water and chemical extinguishing agents, using fire trucks, fire extinguishers, motorized water pumps, and other equipment. The principles of prioritizing people over materials, controlling fires before extinguishing them, and ensuring that key areas are addressed are upheld.

[0003] Firefighting equipment is a crucial tool in firefighting efforts. A search revealed the Chinese patent number CN202110154104.8, which discloses a firefighting drone. The drone includes a main body, with omnidirectional cameras integrated into the top, bottom, front, rear, left, and right ends of the main body for monitoring the drone's surroundings. The drone also incorporates a communication device for communication and data transmission between the drone and an external monitoring center. The drone is equipped with an electric cable winder, a hammering device suspension rope, and a recoilless hammering device. The electric cable winder is integrated into the main body of the drone. The first end of the hammering device suspension rope is fixed to the top of the recoilless hammering device, and the second end is integrated into the electric cable winder. Initially, the control signal line of the recoilless hammering device is bundled with the hammering device suspension rope and wound up via the electric cable winder. This invention expands the application scope and functionality of drones in the firefighting field.

[0027] See also Figure 1-3 , the utility model provides a technical solution:

[0028] A firefighting aircraft, comprising:

[0029] Main structure; the main structure includes an aircraft body 1 and a control box 2 located on the aircraft body 1. Driving arms 4 are symmetrically arranged around the aircraft body 1, and propellers 5 for controlling the lifting of the aircraft body 1 are installed on the driving arms 4. A camera 6 is installed at the bottom of the aircraft body 1. Inside the control box 2, there are a control circuit board, a storage battery, and a wireless communication module. Inside the camera 6, there are an image acquisition module, an infrared thermal imaging module, and a smoke sensor module. The bottom of the aircraft body 1 is symmetrically arranged in a V shape with landing gears 7, and rubber cushions are covered on the landing gears 7. An antenna 3 is arranged on the top of the control box 2.

[0030] In case of a forest fire, this aircraft can be controlled by the staff to take off. Among them, the aircraft body 1 is made of carbon fiber composite material, which is lightweight and high in strength, equipped with a dual-redundancy power system to ensure flight stability, and integrated with a high-precision GPS and an inertial navigation system to achieve precise positioning and autonomous flight; the camera 6 at the bottom of the aircraft body 1 is equipped with an image acquisition module, an infrared thermal imaging module, and a smoke sensor module, which can remotely detect the fire situation, can monitor and analyze the fire source location and the trend of fire spread in real time, and remotely send the fire situation images through the wireless communication module in the control box 2, facilitating the staff to analyze the fire situation and formulate an efficient fire fighting and rescue strategy before arriving at the fire scene while performing the reconnaissance function.

[0031] Meanwhile, please refer to Figure 2-3 :

[0032] It also includes a fire extinguishing mechanism for controlling the fire; the fire extinguishing mechanism includes a notch 8 on one side of the aircraft body 1 and a fire extinguishing bomb 9 in the notch 8; it also includes a positioning mechanism for fixing and dropping the fire extinguishing bomb 9; the positioning mechanism includes two groups of clamping blocks 12 arranged on both sides of the notch 8, and the two groups of clamping blocks 12 respectively clamp the outer walls on both sides of the fire extinguishing bomb 9.

[0033] On the aircraft body 1, baffles 10 are symmetrically arranged on both sides of the notch 8. Electric push rods 11 are fixedly installed on the outer walls of the baffles 10, and the two groups of electric push rods 11 are arranged synchronously. A fixing seat 13 is arranged on the outer wall of the clamping block 12, and the fixing seat 13 is arranged in a U shape. The piston rod end of the electric push rod 11 penetrates through the baffle 10 and is fixedly connected to the center of the outer wall of the fixing seat 13.
