[0002] In the field exploration work of geological environment, the frequency of using drones for exploration is increasing. However, during the exploration process, drones sometimes crash due to malfunctions or power shortage. If they cannot be recovered, certain losses will be caused. The patent with authorization announcement number CN 209795852 U discloses a light and sound alarm device for drones, and discloses the following technical scheme: A light and sound alarm device for drones, including an upper cover and a cover plate, a speaker groove is provided inside the upper cover, a speaker is connected to the speaker groove through a first buckle, a light component groove is provided inside the upper cover, first threaded columns are provided on both sides of the light component groove, a light component is installed inside the light component groove, a battery groove is provided inside the upper cover, a battery is plugged into the battery groove, a limit block is provided on one side of the battery groove, and an acceleration sensor is connected between the two limit blocks through a second buckle. The utility model is provided with an acceleration sensor, which can send out a signal by sensing the change of acceleration. After the circuit board receives the signal of the acceleration sensor, it outputs a signal to the light component to make it send out a warning light, and outputs a signal to the speaker to make it send out a warning sound. The emitted warning light and warning sound can indicate the position of the aircraft.

[0003] However, in the above-mentioned drone light and sound alarm device, after the drone has an accident, the device can only emit warning lights and warning sounds, but in the wild environment, due to environmental factors such as deep roots and dense forests, the warning lights and warning sounds are difficult to be found by searchers. Therefore, the above-mentioned drone light and sound alarm device is not suitable for field exploration work in geological environments. Summary of the invention
