This is an auxiliary rescue device for post-earthquake situations. The complex road conditions and secondary disasters such as aftershocks after an earthquake pose many unknown risks and challenges to rescue operations. This product integrates a "fuse breaking system", which controls signals through physical disconnection. Its core is a highly sensitive relay sensor that can detect soil displacement of 1.5mm and trigger the fuse to break. After the break, the signal conversion module instructs the laser emitter to change color, marking the risk of soil liquefaction or collapse in real time, making geological risks visible and providing clear safety route guidance for evacuees and rescue workers, thereby improving decision-making efficiency. The product is made of lightweight and sturdy aluminum-magnesium alloy material, with a fluorine coating on the surface to enhance corrosion resistance and ground friction. The sensor part adopts an aluminum-rubber wrapped structure with an embedded elastomer-like material, improving the response speed and physical compensation ability to collapse and soil liquefaction. This device provides clear action guidance for rescue workers and disaster victims, builds a safe road network, prevents secondary road collapses caused by soil liquefaction, and effectively reduces the risk of secondary injuries to people at the earthquake site, improving rescue efficiency and safety.
