Abstract: The present disclosure belongs to the technical field of unmanned aerial vehicles, and specifically relates to an airdrop device used with an unmanned aerial vehicle. The airdrop device includes a clamping jaw bearing block, a control panel, a power supply, a power source, and a photosensitive sensor. The clamping jaw bearing block is used to be detachably connected with an unmanned aerial vehicle; the control panel, the power supply, the power source, and the photosensitive sensor are all mounted on the clamping jaw bearing block; and the output end of the power source is provided with an engine arm used to hang a material bag. The power supply, the power source, and the photosensitive sensor are all connected with the control panel; and the control panel receives a light signal detected by the photosensitive sensor and controls the power source to act. The airdrop device used with the unmanned aerial vehicle of the present disclosure has a simple and reasonable structure.
