The invention discloses an underground life saving device. The underground life saving device comprises a tripod, a manual winch, a life saving rope and a life saving hook; the manual winch is mounted on the tripod; the life saving rope is wound on the manual winch; the life saving hook is connected with the life saving rope; the manual winch includes a life saving rope drum, a winch bracket and a manual rocking handle; the life saving rope drum and the manual rocking handle are mounted on the winch bracket; a large gear is mounted at one end of the life saving rope drum; a small gear is mounted on the manual rocking handle; the large gear and the small gear are engaged with each other; the life saving hook mainly consists of two metal hooks; and sponges and winding belts are wound on the metal hooks. The underground life saving device is simple in structure and convenient for use; the life saving hook can firmly hook a body of a person falling into a well without easily releasing, and is wound with the sponges and the winding belts to relieve the paint of the rescued person to a certain extent; and the underground life saving device is more suitable for use by firefighters, and has definite generalization.
Description
technical field [0001] The invention relates to the technical field of underground lifesaving, in particular to an underground lifesaving device. Background technique [0002] At present, there are still many motor-driven wells used for irrigation in rural areas, mostly with a diameter of 20 cm to 70 cm. Because they are located in farmland, they are unattended and lack warning signs. People accidentally fall into the wells, especially those with a diameter of 20 cm. 20 cm to 50 cm, the depth of more than 20 meters of motor-driven wells, due to the small diameter, adult rescuers cannot enter the well to rescue, in addition to the depth, the air is thin, and ordinary rescue tools cannot quickly rescue, which brings great difficulties to the rescue work. [0003] Due to the different calibers of the wells, people generally fall into one of the following four states after falling into the well: one is to fall into the bottom of the well without water; the other is to fall into ...
