Embodiment Construction
[0018] like figure 1 As shown, the "finger bionic grasping device" is similar to the tendon sheath and tendon structure of a finger. A group of ring joints (2) are connected to each other by a group of connecting shafts (1) parallel to each other. One end of the annular joint is connected with a section of solid stainless steel pipe (3), and the stainless steel pipe is riveted on one end of the 32 mm thick-wall rough surface PPR pipe (4) with several rivets (5). Wear a solid soft steel rope (6) in the gap between one side of each connecting shaft and the annular joint. One end of the wire rope is fixed on the stub of the annular joint, and the other end passes through the total length of several sections of PPR pipes that can be plugged in, and is reliably hung on the hook at the lower end of the adjustment screw (8) with wing nut (9).
[0019] Each section of PPR pipe is 4-6 meters, and two holes are punched at both ends, and the stainless steel pipe with holes is inserted ...

The invention discloses a rescue apparatus for a person lost in a well, which comprises one to three same bionic finger grasping devices and an inflated floating oxygen transferring and lighting device. The bionic finger grasping device has a structure similar to peritenon and tendon of a finger, mainly consists of a group of mutually connected ring-shaped joints and a soft wire cable, can freely control the will of a person to finish arc bending of various angles, till achieves spiral winding in an angle larger than 360 degrees, can conveniently extend into the armpit and the cross-leg of the person lost in the well to salvage and lift upwards, can grasp the arm and the lower leg effectively and tightly, and is extremely suitable for saving a child who can not cooperate and a person who has lose consciousness in the well. The inflated floating oxygen transferring and lighting device uses the buoyancy force of an air bag and the lifting force of a rescuer to lift the person dropping in the well from the water, provides oxygen or flowing air, and provides lighting and talking conditions. The collaboration use of the bionic finger grasping device and the inflated floating oxygen transferring and lighting device can rescue the person lost in a well safely, quickly and easily, and the rescue apparatus is particularly suitable for the rescue in a small-bore vertical well.
Description
1. Technical field: [0001] The invention relates to a set of lifesaving equipment, which is especially suitable for lifesaving of vertical wells with a caliber of less than 50 centimeters. It has the characteristics of simple structure, safety and reliability, ingenious design, low manufacturing cost, short life-saving time, high success rate, etc. It belongs to emergency supplies such as firefighting and special services. 2. Background technology: [0002] TV, newspapers and other media often report on how soldiers from the police, firefighters, and secret services rescued children who fell into wells, or how the local government, police, hospitals, and the masses jointly rescued those who fell into wells. To sum up, there are the following methods for rescuing those who fell into the well: one is to release the rope into the well, and let the person who fell into the well bind himself and then pull out, but the person who fell into the well is usually a young child or has ...
