Abstract

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

Life saving apparatus for persons falling into well

One, affiliated technical field:

The present invention relates to a cover buoyant apparatus, be particularly useful for the lifesaving of bore less than 50 centimetres of perpendicular shape wells.Have simple in structure, safe and reliable, ingenious, the low cost of manufacture of design and characteristics such as lifesaving needs the time short, and success rate is big, belong to emergency treatment articles such as fire-fighting, special duty.

Two, background technology:

The process that often has soldiers such as media report public security, fire-fighting, special duty such as TV, newspaper to rescue the well children, or local government, public security, hospital, the masses unite the process of succouring the personnel to fall into well.Integrate, the relief person down the well has following method: the one, in well, discharge rope, and allow the person down the well after tiing up, pull out, but the person down the well is generally young child, perhaps loses consciousness; The 2nd, the salvor with body material slight of stature hangs down upside down with rope, then the drowning people is rescued; The 3rd, employ large-scale excavating equipment from excavating on one side, wasting time and energy and having earth, cement block to fall injures the personnel's that rescued danger by a crashing object.

The present invention overcome the defective of above three kinds of common methods, designed a cover relief personnel to fall into well equipment special, can be safely, fast, easily the person down the well is sued and laboured.

Three, summary of the invention:

This cover equipment mainly comprises one to three identical " point bionical grabbing and tie up device " (being called the snakelike hook of Shi Shi for the time being), function be used for the person down the well grabbed tie up, salvage, on carry.Also comprise one " inflation come-up oxygen therapy lighting device ", function is the person down the well to be passed the imperial examinations at the provincial level from water rise, and moving air or oxygen are provided, and illumination and conversation condition are provided; Also having a critical function is exactly to tie up device and upwards pull out in person down the well's the process with pointing bionical grabbing, guaranteeing that the person down the well can not fall into the shaft bottom by halfway once more.

Need to prove that when succouring the personnel to fall into well under complicated state, above summary of the invention can play a key effect, and does not use other equipment and article simultaneously but do not repel, for example existing utensils such as telescope, oxygen cylinder, air pump, illuminating lamp.

Four, description of drawings:

Fig. 1 is the principle assumption diagram of " point bionical grabbing and tie up device " of the present invention.

Fig. 2 is the structure chart of " inflation come-up oxygen therapy lighting device " of the present invention.

Among the above figure:

1, connecting axle 2, shackle-joint

3, stainless steel tube 4, the heavy wall exasperate PPR that can peg graft pipe

5, rivet 6, steel wire rope

7, canvas or rubber sheath 8, adjustment screw mandrel

9, wing nut 10, rubber pneumatic bag,

11, inflating catheter 12, internal layer bouffancy cloth cover

13, outer bouffancy cloth cover 14, the heavy wall exasperate PPR that can peg graft pipe

15, oxygen hose 16, oxygen outlet

17, illumination, communicator 18, illumination, conversation lead

Five, the specific embodiment:

As shown in Figure 1, " point bionical grabbing and tie up device " is similar to the stndon sheath and the tendon structure of finger.With one group of connecting axle parallel to each other (1), one group of shackle-joint (2) is connected to each other.One end of shackle-joint is connected with one section firm stainless steel tube (3), and stainless steel tube is managed an end of (4) at 32 millimeters heavy wall exasperate PPR with several rivets (5) riveting.In the space of side of each connecting axle and shackle-joint, be installed with a firm soft steel wire rope (6).Steel wire rope one end is fixed on the minor details of shackle-joint, and the other end passes plug-in several sections PPR pipe length overall, hangs over reliably on the hook of adjustment screw mandrel (8) lower end that has wing nut (9).

PPR manages every section 4-6 rice, and two holes are respectively stamped at two ends, by stainless steel tube with holes, plugs with another section PPR pipe, so that arbitrarily determine length.Exasperate design is anti-skidding in order to salvage.

As shown in Figure 2, " inflation come-up oxygen therapy lighting device " is made of rubber pneumatic bag, inflating catheter, ectonexine bouffancy cloth cover, can peg graft heavy wall exasperate PPR pipe, oxygen hose, illumination, communicator etc.Bondage is in the lower end of heavy wall exasperate PPR pipe (14) securely for internal layer bouffancy cloth cover (12) and outer bouffancy cloth cover (13), and its effect is to rubber pneumatic bag (10) duplicate protection.Rubber pneumatic bag (10) is connected with inflating catheter (11).Inflating catheter (11), oxygen hose (15), illumination and conversation place exasperate PPR to manage the cavity of (14) with lead (18) etc.Oxygen outlet (16) and illumination, communicator (17) are installed in the appropriate location of PPR pipe (14) lower end.

When the vertical shaft person down the well is implemented to rescue, can determine at first to use " point bionical grabbing and tie up device " or " inflation come-up oxygen therapy lighting device " according to actual conditions.Generally speaking, dim when light in the well, when being badly in need of drowning people's oxygen supply again, can at first " inflation come-up oxygen therapy lighting device " be probeed in the well water by drowning people's one side, make airbag aeration afterwards, utilize air bag buoyancy and rescuer's upper lifting force amount, make person down the well's mouth and nose leave the water surface as early as possible, illumination and oxygen are provided simultaneously.Then extend under person down the well's hip with one to three " point bionical grabbing and tie up device ", oxter or other suitable positions, be pulled upwardly and adjust screw mandrel (8), and screw wing nut (9) immediately, this moment, shackle-joint was just crooked in turn, can be arbitrarily by becoming the hook-shaped of circular arc vertically downward, just can grab the person down the well tie up, salvage, on carry." inflation come-up oxygen therapy lighting device " then carried on following closely, guarantees upwards to pull out in person down the well's the process, increases safety factor, and the person down the well can not fall into the shaft bottom by halfway.Characteristics such as two kinds of this cover equipment devices are collaborative mutually, and having lifesaving needs the time short, and success rate is big can be safely, fast, easily the person down the well is sued and laboured.
