Well

Design of a small underground rescue device. This device consists of three parts: the device's main body for transportation, a telescopic mechanical arm, and related rescue and first aid products. In the event of a fall underground, the device is transported to the wellhead. Through adjusting the angle of the mechanical arm, the rescue and first aid products are delivered to the rescuers. These products include oxygen generators to supply oxygen to the rescued, gas masks to protect the rescued from harmful gases underground, searchlights to provide illumination underground for rescue operations, and ropes for pulling the rescued to the surface, significantly enhancing rescue efficiency.
