Emergency escape ladder on ice

Abstract

The invention discloses an ice rescue ladder, comprising a flexible interface, a plurality of hard supporting surfaces, a plurality of pedals and an active hinge; wherein, two group of hard supporting surfaces are cuboid sheets made of timber or plastic, supporting and widening force area; the flexible interface is fixed at the bottom of the hard supporting surface and is made of rubber or foam; a plurality of pedals made of timber or plastic are fixed on the hard supporting surface for rescuers standing or moving; the ice rescue ladder is multistage; the stages are flexibly hinged. The ice rescue ladder has the advantages that the ladder has simple structure and can enlarge the force area to the largest extent, avoiding ice breakage; since the ladder has considerable hardness and bearing capacity, rescuers will be safe and convenient to carry out rescue on the pedals; the rescue ladder greatly improving life-saving efficiency is suitable for ice rescue.

Description

technical field [0001] The invention relates to a life-saving ladder, especially a life-saving ladder used on ice. Background technique [0002] In the cold winter, rivers, lakes, ponds and other places will freeze. Every year there are deaths caused by falling into ice caves. Even if it is discovered in time and rescue is taken, it is very dangerous because of the lack of effective life-saving equipment. [0003] In the "air bridge" patent (application number: 200620058830.0) disclosed in Chinese Patent No. CN2905887, the bridge body is composed of an inner layer of mesh cloth forming a closed inner cavity and an outer layer of mesh cloth adhered to the outside of the inner layer. The body is provided with an air valve communicating with the inner cavity. The disadvantages of this patent are: the ice surface has a certain hardness and bearing capacity, and this patent is relatively soft as a whole, and people standing on it cannot effectively expand the force-bearing are...

AI Technical Summary

Problems solved by technology

The disadvantages of this patent are: the ice surface has a certain hardness and bearing capacity, and this patent is relatively soft as a whole, and people standing on it cannot effectively expand the force-bearing area and avoid the ice surface from breaking; it is inconvenient to operate; and it is easy to be Ice cubes break and deflate

The weak point of this patent is: it is based on the user's original clothes, and waterproof sealing is carried out. For many occasional ice falling events, this patent cannot be implemented.
