Problems solved by technology

[0005] When some foam fire extinguishers are in use, they need to be turned upside down (to mix the two solutions in the foam fire extinguisher) and fully shaken to effectively extinguish the fire. However, the above-mentioned fire rescue drone cannot be inverted and shake the foam fire extinguisher;

Embodiment 1

[0048] see Figure 1-Figure 5 , an unmanned aerial vehicle for fire rescue, including a body 1, a mounting cabinet 2 is fixedly installed at the bottom of the body 1, a connecting block 23 is rotatably provided at the bottom of the mounting cabinet 2, and a driving box 27 is movably provided below the connecting block 23 to drive the Four sides of the box 27 are movably provided with side plates 3;

[0049] A screw 7 is rotated between the inner walls of the left and right sides of the side plate 3. The left side of the outer wall of the screw 7 and the right side of the outer wall are respectively provided with a first thread 8 and a second thread 9 with opposite directions of rotation. A first nut 10 and a second nut 11 are threadedly connected to the outer walls of the two threads 9 respectively. The top and bottom of the first nut 10 and the second nut 11 are fixedly mounted with L-shaped rods 12 , and the ends of the four L-shaped rods 12 extend A jacket 13 is fixedly co...

Embodiment 2

[0057] see Figure 7 , On the basis of Embodiment 1, the inside of the drive box 27 is evenly provided with four second motors 28, and the output shafts of the four second motors 28 are respectively fixedly connected with the four side plates 3;

[0058] The operation of the second motor 28 can drive the side plate 3 at the top of its output shaft to rotate, and the rotation of the side plate 3 can adjust the inclination angle of the side plate 3, so that the fire extinguisher 15 can spray fire-extinguishing foam at different angles, and the fire-extinguishing range is wider. If the fire extinguisher 15 needs to be inverted and mixed, the side plate 3 can be turned upside down to make the fire extinguisher 15 upside down. After the fire extinguisher 15 is inverted, the solution in the fire extinguisher 15 can be fully mixed, thereby generating a large amount of fire extinguishing gas.

Embodiment 3

[0060] see Image 6 and Figure 8 , on the basis of Embodiment 1 and Embodiment 2, a bottom case 24 is provided below the drive box 27, and the four corners of the bottom box 24 and the four corners of the bottom of the connecting block 23 are fixedly connected by four sliding rods 25, and four The slide bars 25 are all sleeved with sliding sleeves 26 , and the four sliding sleeves 26 are respectively fixed and installed on the four corners of the drive box 27 . The four sliding bars 25 are also sleeved with springs 38 , which are fixedly connected to the connecting block 23 . between the bottom of and the top of the sliding sleeve 26;

[0061] An inner cavity 29 is formed inside the bottom box 24 , a third motor 30 is fixedly installed on the inner side wall of the inner cavity 29 , a rotating column 31 is fixedly installed on the top of the output shaft of the third motor 30 , and a convex block is fixedly installed on the outer wall of the rotating column 31 32, the inner...

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses an unmanned aerial vehicle for fire rescue. The lower part of the block is movably provided with a driving box, and the four sides of the driving box are movably provided with side plates, and the side plates are clamped by jackets and are provided with a fire extinguisher; Press down so that the foam can be ejected normally, and the body carries the side panels to fly in the air, which can carry out fire extinguishing operations in locations that are inaccessible or difficult for the staff, with small limitations, which not only ensures the safety of the staff, but also better Complete fire rescue work. The invention has novel design and simple structure, and has the advantages of convenient fire extinguishing, and the ability to invert and shake the foam fire extinguisher.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle for fire rescue. Background technique [0002] Unmanned helicopters have unique flight performance and use value - compared with manned helicopters, unmanned helicopters have the characteristics of no casualties, small size, low cost, and strong battlefield survivability; The human helicopter can take off and land vertically, hover in the air, and fly in any direction. Its take-off and landing site is small, and it does not need to be equipped with a complex and large-scale launch and recovery system like fixed-wing drones; because of these characteristics, no one has The application range of the drone is also getting wider and wider, and it is widely used in aerial photography, agriculture, plant protection, express transportation, fire rescue, surveying and mapping, news reporting, power inspection, and other fields, which greatly exp...
