A safety protection device based on outdoor deep well rescue

Abstract

The invention relates to the technical field of outdoor rescue equipment and discloses a safety protection device based on outdoor deep well rescue. The safety device comprises a hoisting platform, wherein a hanging ring is fixedly mounted at the top end of the hoisting platform; a pulley pedestal is fixedly mounted in the middle of the bottom end of the hoisting platform; six supporting lugs areuniformly arranged at the outer edge of the bottom end of the hoisting platform; supporting auxiliary racks are in pin joint in the supporting lugs; and air pressure cylinders are arranged in the middle parts of the supporting auxiliary racks. According to the safety protection device based on outdoor deep well rescue, by arranging the supporting auxiliary racks and the air pressure cylinders, theeffective inner diameter of a spatial structure formed by the six supporting auxiliary racks can be increased effectively by means of an external inflating device, so that the safety protection device is suitable for narrow motor-pumped wells of different inner diameters. Meanwhile, matched with a telescopic round rack and an elastic air bag, the inner diameter of the bottom of the protection device can be adjusted effectively, so that the safety protection device is further suitable for trapped persons of different body sizes, and is relatively wide in controllability and application range.

Description

technical field [0001] 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 technique [0002] Deep well rescue is one of the common rescue operations of the fire brigade. In some areas, due to the needs of building irrigation, deep wells are often dug on the spot to fetch water. In the wild, it is covered with weeds, making it difficult for passers-by to find and fall into it by mistake, and because the depth of the well is large and the opening is small, it is very easy to cause body damage to pedestrians who fall by mistake and be trapped in the well. Firefighters used rescue tripods and safety belts to lower into the well to free the trapped people. [0003] However, the existing rescue safety belts can only simply fix the waist and crotch of the trapped or firefighters. During the process of lowering or pulling up the rescue, the trapped and firefighters' limb...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a safety protection device based on outdoor deep well rescue, which can provide comprehensive protection for rescuers and trapped persons, prevent scratching damage between them and the well wall, and have high rescue effects and reliability The advantage is that the existing rescue safety belt can only simply fix the waist and crotch of the trapped or firefighters. In the process of lowering or pulling up the rescue, the trapped and firefighters' limbs will always Exposed in the well wall, frictional contact with the narrow well wall requires firefighters to constantly adjust their positions in the air to avoid scraping between the well walls, which consumes a lot of physical strength for rescuers and is invisible The effective rescue time is prolonged, and the danger of the trapped persons is increased, and when the trapped persons are pulled up and rescued, due to the poor physical fitness of the trapped persons, they may even become comatose due to being trapped for a long time. It is impossible to adjust its position in the air like firefighters, so as to avoid frictional contact between the limbs and the well wall, which makes it easy for the trapped people to cause secondary scratch damage during the rescue process, resulting in the overall rescue effect. Poor, and there are many security risks
