Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a material delivery and rescue unmanned aerial vehicle based on infrared thermal imaging. Background Art

[0002] Natural disasters are sudden, and the key to disaster emergency rescue is a quick response after the disaster occurs. In recent years, my country has responded quickly to emergency search and rescue and disaster rescue. The key factor to improve the efficiency of disaster emergency rescue is to quickly and accurately obtain disaster information after the disaster occurs. Due to the low efficiency of manual search and rescue, good collaborative work requirements in complex environments, and the risk of secondary disasters, manual search and rescue also faces.

[0003] After decades of development, drones are now relatively mature from a technical perspective. Equipped with a variety of sensors, drones have the characteristics of strong real-time performance, fast maneuverability, high image resolution, economy and convenience, and the ability to operate in high-risk areas. They are very suitable for emergency rescue of various natural disasters. Search and rescue using drones has become an urgently needed method.

[0004] The existing Chinese patent with the announcement number CN213109794U discloses a multifunctional UAV transport and delivery device, which includes a UAV, on the frame of which four support rods are vertically arranged downward, and the four support rods are arranged in a square. The top ends of the support rods are fixedly connected to the frame of the UAV by bolts, and the bottom ends of the support rods are horizontally fixedly connected to a placement cross bar, which also includes four vertical plates.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: after the flip bottom plate of the device is flipped open for material delivery, the flip bottom plate cannot be automatically closed, and improvement is needed; therefore, in view of the above problems, a material delivery and rescue drone based on infrared thermal imaging is proposed. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve the above-mentioned technical problems, the utility model proposes a material delivery and rescue drone based on infrared thermal imaging.

The rescue materials in the emergency rescue cargo hold 2 are carried by the drone body 1 for delivery. The driver 6 drives the screw 32 to rotate and adjust the height of the bracket 31. When the bracket 31 is at the top, the card plate 34 is pressed against the base 1 23 and the base 2 24, thereby closing the bottom of the cabin 21. When it is necessary to deliver materials, the bracket 31 descends to increase the height of the cabin 21, leaving space for the materials to fall off, and the base 1 23 and the base 2 24 are rotated open, so that the materials fall from the cabin 21, thereby achieving the delivery of materials.

[0028] The surface of the base 23 is recessed upward to form a mounting groove 4, and a thermal imager 5 is fixedly connected inside the mounting groove 4. The thermal imager 5 is used to detect the disaster-stricken people, achieve target positioning, and move to the vicinity of the rescuers to deliver supplies.

[0029] A lead screw 2 35 is threadedly connected at the center of the card plate 34, and a driver 2 7 is fixedly connected to the lower side wall of the card plate 34, and the driving end of the driver 27 is fixedly connected to one end of the lead screw 2 35. The lead screw 2 35 is driven by the driver 27 to rotate so that the card plate 34 slides horizontally. When the bracket 31 is located at the top, the card plate 34 slides to the maximum extent to the side of the bracket 31 to limit the base 1 23 and the base 2 24. When the bracket 31 is lowered, the card plate 34 slides to the maximum extent to the side away from the bracket 31 to avoid blocking the falling of materials.

[0030] The bracket 31 is provided in a T-shape.

[0031] The bottom of the bracket 31 is symmetrically fixedly connected with a spring buffer 36, and the bottom end of the spring buffer 36 is fixedly connected with a support seat 37. When dropping materials, the drone body 1 descends to the ground and is supported by the support seat 37. At the same time, the spring buffer 36 buffers the impact force during the descent. Compared with traditional high-altitude delivery, the damage to the rescue materials caused by the impact force of the fall can be reduced.

[0032] The lifting range of the lead screw 32 is greater than the height of the rescue materials.

[0033] Embodiment 2

[0034] For comparison with Example 1, please refer to Figure 5 As shown, the utility model provides another embodiment, an opening and closing assembly 8 is installed on the cabin body 21 and the cabin cover 22, and the opening and closing assembly 8 includes a plurality of drivers 81, and the drivers 81 are fixedly installed on the inner lower side wall of the cabin body 21.

[0035] The driving end of the driver three 81 is fixedly connected to a threaded telescopic rod 82, and the top of the threaded telescopic rod 82 is fixedly installed on the bottom of the hatch cover 22. The driver three 81 drives the threaded telescopic rod 82 to rotate, thereby driving the hatch cover 22 to rise and fall. When the hatch cover 22 rises, the cabin body 21 is opened to facilitate the placement or removal of rescue supplies. When the hatch cover 22 descends, the cabin body 21 is closed to prevent the rescue supplies from falling during transportation.

[0036] According to the personnel in this field, according to the actual situation, the driver 1 6, the driver 2 7, the driver 3 81 and the thermal imager 5 should be electrically connected to the control system of the UAV body 1 to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the working order. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0037] It is worth noting that: the material delivery and rescue drone based on infrared thermal imaging in this scheme has parts that are the same as the parts of the existing material delivery and rescue drone based on infrared thermal imaging, so this scheme does not describe all the existing parts, but only describes some improved parts.

[0038] The working principle is that the rescue materials in the emergency rescue cargo hold 2 are carried out by the drone body 1 for delivery, and the driver 6 drives the screw 32 to rotate and adjust the height of the bracket 31. When the bracket 31 is at the top, the base 1 23 and the base 2 24 are pressed against by the clamping plate 34, so as to close the bottom of the cabin 21. When the materials need to be delivered, the bracket 31 descends to increase the height of the cabin 21, leaving space for the materials to fall off, and the base 1 23 and the base 2 24 are rotated open, so that the materials fall from the cabin 21, and the delivery of the materials is realized. After the delivery of the materials is completed, the bracket 31 rises again and pushes the base 1 23 and the base 2 24 to rotate and close the bottom of the cabin 21 through the clamping plate 34.

[0039] When dropping supplies, the drone body 1 descends to the ground and is supported by the support seat 37. At the same time, the spring buffer 36 cushions the impact force during the descent. Compared with traditional high-altitude delivery, the impact force generated by the fall can reduce the damage to the rescue supplies.

[0040] The threaded telescopic rod 82 is driven to rotate by the driver 3 81, thereby driving the hatch cover 22 to rise and fall. When the hatch cover 22 rises, the cabin body 21 is opened to facilitate the placement or removal of rescue supplies. When the hatch cover 22 descends, the cabin body 21 is closed to prevent the rescue supplies from falling during transportation.
