Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) application technology, specifically to an emergency rescue UAV life detection device. Background Technology

[0002] Natural disasters such as fires, earthquakes, and mudslides cause numerous casualties, making it crucial to rescue trapped and injured individuals within the critical 72-hour window. However, the complex disaster environment makes traditional detection methods difficult to deploy, further increasing the challenge of finding trapped individuals. Therefore, a life detection system based on an unmanned aerial vehicle (UAV) platform was proposed for complex disaster environments. This system leverages the maneuverability and flexibility of UAVs to quickly search disaster areas and uses non-contact life detectors to locate trapped individuals, providing valuable information for subsequent rescue efforts.

[0003] In the prior art, Chinese utility model application number CN202121199457.1 discloses an airborne life detection radar for unmanned aerial vehicles (UAVs), including a radar device and a housing for mounting the radar device. The radar device includes an antenna, a power module, a radio frequency module, and a baseband module. A shock-absorbing device is also present on the housing, comprising a shock-absorbing shaft, a shock-absorbing spring nested on the shock-absorbing shaft, and a shock absorber cover plate. The shock-absorbing shaft extends out of the housing surface and is connected to the housing through the shock absorber cover plate. This utility model device is directly mounted on a carbon fiber plate at the bottom of the UAV, enabling life detection and effectively reducing interference from UAV vibrations. The shock-absorbing device employs a dual shock-absorbing structure to achieve optimal shock absorption.

[0004] While the above-mentioned technical solutions reduce the vibration impact of drones on life detection devices, different drone models have significant differences in their airframe structure, center of gravity distribution, and vibration conditions. Fixed installation locations cannot be adapted to multiple drone platforms, limiting the versatility of life detection devices on different drones and increasing the difficulty of installation and debugging. Therefore, we need to propose an emergency rescue drone life detection device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: an emergency rescue drone life detection device, comprising:

[0026] The drone body 1, and two sets of bottom beams 2 installed at the bottom of the drone body 1;

[0027] A support assembly 3 is detachably installed between two sets of bottom beams 2, and two sets of adjustable connectors 4 are slidably installed on the support assembly 3. A life detection radar device 5 is installed below the two sets of adjustable connectors 4, and multiple sets of shock absorption devices 6 connected to the two sets of adjustable connectors 4 are installed on the life detection radar device 5.

[0028] Both sets of adjustable connectors 4 include sliders 41, crossbeams 42 and two sets of connecting bolts 45. The sliders 41 are integrally formed in the middle of the upper surface of the crossbeams 42. Both ends of the upper surface of the crossbeams 42 are provided with adjustment grooves 43 for the connecting bolts 45 to slide. The lower end of the connecting bolts 45 is threaded into the shock absorber 6.

[0029] A guide plate 46 is provided at the upper end of the connecting bolt 45 located in the adjusting groove 43. The outer diameter of the guide plate 46 is larger than the outer diameter of the connecting bolt 45. The cross section of the adjusting groove 43 is cross-shaped. A washer 47 is sleeved on the lower outer side of the connecting bolt 45. The washer 47 is located between the shock absorber 6 and the crossbeam 42. Through the shape of the adjusting groove 43, the connecting bolt 45 can be adjusted to any position in the adjusting groove 43 under the action of the guide plate 46. This allows the position of the connecting bolt 45 to be adapted to the shock absorber 6, improving the disassembly and assembly efficiency of the life detection radar device 5. Furthermore, the washer 47 improves the installation stability of the shock absorber 6.

[0030] The support assembly 3 includes a fixed beam 31. The lower surface of the fixed beam 31 has a groove 32 for sliding the slider 41. The groove 32 has a T-shaped cross section. A locking bolt 44 is threaded to the middle of the lower surface of the beam 42. The top of the groove 32 has multiple sets of positioning holes 33 for the locking bolt 44 to be inserted. By screwing the locking bolt 44 into the corresponding positioning hole 33, the stability of the beam 42 after position adjustment is ensured, thereby ensuring the stability of the life detection radar device 5 after installation.

[0031] Both sides of the fixed beam 31 are fixedly connected to side frames 34. The lower ends of the two sets of side frames 34 are clamped with anti-slip pads 35. The life detection radar device 5 is set between the two sets of side frames 34. The side frames 34 are used to support the UAV body 1 for lifting and lowering, thereby avoiding contact between the life detection radar device 5 and the ground, and further ensuring the service life of the life detection radar device 5.

[0032] Two sets of side blocks 36 are fixedly connected to both sides of the fixed beam 31. Two sets of mounting holes are opened on one side of the fixed beam 31, and the two sets of mounting holes are located between the two sets of side blocks 36. The bottom beam 2 is located between the two sets of side blocks 36, so that the fixed beam 31 can be quickly embedded between the two sets of bottom beams 2 to ensure the alignment of the mounting holes with the guide holes.

[0033] The fixed beam 31 is snapped between the two sets of bottom beams 2. Two sets of guide holes are opened on the opposite side of the two sets of bottom beams 2, and two sets of screws 23 that pass through the two sets of mounting holes are inserted into the two sets of guide holes respectively. One end of the two sets of screws 23 is fixedly connected to the connecting plate 22, and the other end of the two sets of screws 23 is threadedly connected to the locking nut 25. The screws 23 can easily and quickly pass through the guide holes and mounting holes. The connecting plate 22 restricts the insertion position of the screws 23, and the locking nut 25 improves the stability of the positioning of the fixed beam 31.

[0034] One side of one set of bottom beams 2 is provided with a T-shaped knob 21, and one side of the connecting plate 22 is provided with a through hole 24 for the T-shaped knob 21 to pass through. The through hole 24 is arranged in a straight line. The T-shaped knob 21 facilitates the insertion of the screw 23 into the fixed beam 31 to pre-position the connecting plate 22, thereby facilitating the secondary tightening of the locking nut 25 and improving the stability of the support component 3 installation.

[0035] The shock absorption device 6 includes a shock absorption shaft, a shock absorption spring nested on the shock absorption shaft, and a shock absorber cover plate. The upper end of the shock absorption shaft is provided with a threaded hole for the connecting bolt 45 to be threaded. The shock absorption device 6 can reduce the impact of the vibration generated by the UAV body 1 during flight on the life detection radar device 5.

[0036] In use, according to the position of the shock absorber 6 on the life detection radar device 5, first loosen the locking bolt 44, adjust the relative position of the two sets of crossbeams 42, and then make the two sets of crossbeams 42 and the two sets of shock absorbers 6 on the same plane. Then adjust the position of the connecting bolt 45 in the adjusting groove 43 so that the connecting bolt 45 connects with the screw hole on the shock absorber 6. After the shock absorber 6 presses the shim 47, the installation of the life detection radar device 5 is completed, which improves the installation efficiency of the life detection radar device 5, and makes disassembly and assembly convenient, thus improving the maintenance efficiency of the life detection radar device 5.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
