Description

Technical Field

[0001] This utility model relates to the field of cleaning machinery technology, and in particular to a rescue site cleaning robot. Background Technology

[0002] Post-disaster relief and reconstruction work faces enormous challenges. Disaster sites often contain multiple sources of danger: on the one hand, there is a risk of biological contamination, such as the remains of victims, bloodstains, and excrement that may carry pathogens; on the other hand, there is a significant risk of chemical contamination, including hazardous waste from social sources such as cleaning agents, pesticides, herbicides, paints, solvents, and oily substances (such as fuel and lubricating oil from damaged vehicles or gas stations) left at the scene, which can easily cause soil and water pollution and even trigger secondary environmental disasters.

[0003] Currently, post-disaster site cleanup mainly relies on a combination of manual labor and heavy machinery. Manual cleanup is not only inefficient and slow, but also exposes workers to multiple risks, including infection, poisoning, secondary collapses, and injuries from sharp objects, placing immense pressure on rescue personnel's safety. While heavy machinery possesses strong transport capabilities, its mobility is poor in structurally unstable, confined, or complex terrain environments. Utility Model Content
