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 , a kind of unmanned aerial vehicle for fire rescue, comprising a body 1, the bottom of the body 1 is fixedly installed with an installation cabinet 2, the bottom of the installation cabinet 2 is rotatably provided with a connecting block 23, and a driving box 27 is movable below the connecting block 23. The four sides of the box 27 are all movable with side panels 3;

[0049] A screw 7 is arranged to rotate between the inner walls of the left and right sides of the side plate 3, and 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 screw thread 8 and a second screw thread 9 opposite in direction of rotation. The outer walls of the two threads 9 are respectively threaded with a first nut 10 and a second nut 11, the top and bottom of the first nut 10 and the second nut 11 are fixedly equipped with L-shaped rods 12, and the ends of the four L-shaped rods 12 extend A jacket 13 ...

Embodiment 2

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

[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. For some For the fire extinguisher 15 that needs to be inverted and mixed, the side plate 3 can be completely turned over, so that the fire extinguisher 15 is turned upside down. After the fire extinguisher 15 is turned upside down, the solution in the fire extinguisher 15 can be fully mixed, thereby generating a large amount of fire extinguishing gas.

Embodiment 3

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

[0061] The inside of the bottom box 24 is formed with an inner chamber 29, the inner wall of the inner chamber 29 is fixedly installed with a third motor 30, the top of the output shaft of the third motor 30 is fixedly installed with a rotating column 31, and the outer wall of the rotating column 3...

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses a fire rescue unmanned aerial vehicle which comprises a vehicle body, wherein a mounting cabinet is fixedly mounted at the bottom of the vehicle body, a connecting block is rotatably arranged at the bottom of the mounting cabinet, a driving box is movably arranged below the connecting block, and side plates are movably arranged on the four sides of the driving box; a fire extinguisher is clamped on the side plate through a jacket; the side plate can fix the fire extinguisher and can tightly press a pressing handle of the fire extinguisher, so that foam can be normally sprayed out, the machine body carries the side plate to fly in the air, fire extinguishing operation can be conducted at the position where workers cannot reach or are difficult to reach, limitation is small, safety of the workers is guaranteed, and the fire rescue work can be better completed. The fire rescue unmanned aerial vehicle is novel in design and simple in structure, and has the advantages that fire extinguishing is convenient, and the foam fire extinguisher can be inverted and shaken.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a drone 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 manned helicopter can take off and land vertically, hover in the air, and fly in any direction. Its takeoff and landing space is small, and it does not need to be equipped with a complex and large-scale launch and recovery system like a fixed-wing UAV; The scope of application of drones is also becoming wider and wider, widely used in aerial photography, agriculture, plant protection, express transportation, fire rescue, surveying and mapping, news reports, power inspections, etc., greatly expanding the use of drones themselves; [0003] For example, the Chinese patent announcement number is: the inven...
