Description

Safety device based on outdoor deep well rescue

Technical Field

The invention relates to the technical field of outdoor rescue equipment, in particular to a safety protection device based on outdoor deep well rescue.

Background

Deep well rescue is one of the common rescue actions of fire fighting troops, in some areas, due to the requirement of building irrigation, deep wells are frequently dug in situ to get water, after drying up or abandoning, due to the lack of effective management measures, holes grow full of wild weeds due to long-term exposure in the field, passing pedestrians are difficult to find and fall into the holes by mistake, and due to the fact that the depth of a motor-pumped well is large and the holes are small, the missing pedestrians are easily damaged by the machine body and are trapped in the motor-pumped well, and only fire fighters can be relied on to utilize rescue tripods and safety belts to fall into the well to rescue out the trapped people.

However, the existing rescue safety belt can only simply fix the waist and the crotch of trapped or firefighters, the limbs of the trapped and firefighters can be always exposed in the motor-pumped well and are in frictional contact with the narrow well wall in the process of lowering or lifting rescue, the firefighters need to be continuously suspended to adjust the positions of the firefighters so as to avoid scraping between the well walls, the physical consumption of the firefighters is high, the effective rescue time is invisibly prolonged, the danger of the trapped people is increased, and when the trapped people are lifted and rescued, the body quality of the trapped people is poor, even the coma phenomenon occurs due to long-time trapping, the trapped people can not be suspended to adjust the positions of the trapped people like the firefighters, so that the frictional contact between the limbs and the well wall is avoided, and the trapped people are very easy to cause secondary scraping damage in the process of rescuing, so that the whole rescue effect is poor and more potential safety hazards exist.
