Fig. 6 and 7 show the detail of the flexible cord 10 entering inside and finally fixed on the lower light wall of the external gear ring 3.
An annular containing cavity is formed among the supporting chassis 1, the air inlet connecting disc 2 and the inflatable end cover 3, an air passing channel communicated with the annular containing cavity and the double-layer flexible inflatable bag 9 is processed on the air inlet connecting disc 2, and the air passing channel and the annular containing cavity form an air passage together. After the double-layer flexible inflatable bag 9 is folded and inflated, gas enters the air passage and the double-layer flexible inflatable bag 9 through an inflation port on the inflatable end cover 6, and the expansion rescue of the double-layer flexible inflatable bag 9 is realized. Preferably, the air passage channel is an annular air passage channel.
Working process
Referring to the drawing, firstly, the double-layer flexible inflatable bag 9 is folded inwards, at the moment, 4 flexible ropes 10 are in a loose state, the rocker arm 8 or the starting motor is rotated clockwise, the gear 4 is rotated, the outer gear ring 3 is driven to rotate at the same time, 4 flexible ropes 10 fixed on the outer ring transmission gear 3 are simultaneously contracted and are in a contracted state, then the double-layer plastic bag 9 is folded inwards, the gear rocker arm 8 is rotated clockwise, and the contraction speed of the 4 flexible ropes 10 is almost the same as the inward folding speed of the double-layer plastic bag 9 until the double-layer plastic bag 9 is folded inwards to the upper end of the supporting cylinder 5. At this time and to ensure that the total height of the folded stack of the double-layered plastic bag 9 is less than the vertical height of the support cylinder 5. The supporting cylinder 5 plays a role in assisting in guiding the folded double-layer flexible inflatable bag 9 to reach the shoulder part, and at the moment, the head of a human body enters the supporting cylinder 5 and has a certain supporting and protecting effect on the head of the human body such as children. When the rescue is needed, the robot is slowly put along the well wall until the lower part of the supporting cylinder 5 reaches the shoulder of the trapped person, and the upper inflatable end cover is fixed by the related device.
The air pump valve is opened to inflate the air holes of the air channel through the inflation end cover 6, the inflatable bag 9 begins to expand slowly, the 4 soft ropes 10 are in a tensioned state, the air pump valve is controlled to enable constant-pressure stable air intake, then the rocker arm 8 is rotated anticlockwise slowly or the rotating speed of the motor is kept slow, the soft ropes 10 wound on the lower portion of the outer gear ring 3 are released, the speed of the released soft ropes 10 is kept almost the same as the expansion speed of the inflatable bag 9, the purpose of controlling the descending speed of the individual portions of the inflatable bag 9 to be extremely uneven is achieved, and therefore the lower portion of the inflatable bag 9 is enabled to. Constantly inflate, the air bag 9 is close even downwards inflation and rushes out, the air bag 9 that becomes four layers after folding this moment makes following motion, when the inner layer of air bag 9 rushes out and reaches the buttock, two-layer gasbag is at first because the static friction power is too big between with the health, static motion, continue to inflate, make two-layer folding gasbag in the innermost slowly rush out and change into outer gasbag gradually (two-layer folding gasbag in the innermost outwards rush out and adjacent contact layer this moment be equivalent to pure roll), continue between outer gasbag and the health because of static friction power keeps motionless, so slowly circulate down, two-layer gasbag that inside folding at last rushes out below the buttock, rush out partial conversion to outer gasbag, reach trapped knee at last. After reaching the knee, the inflation pressure is gradually increased, the fitting area between the inner wall of the air bag and the body of the trapped person is gradually increased, and finally the friction force between the double-layer inflatable bag 9 and the body of the trapped person is gradually increased. As shown in fig. 7, the intermediate object simulates a trapped person, and the inner layer of the double-layer inflatable bag 9 wraps the trapped person.
When the double-layer inflatable bag 9 expands to break through the buttocks, the pressure intensity is increased, and when the pressure intensity reaches a certain value, the friction force between the inflatable bag and the trapped person is larger than the sum of the gravity of the trapped person and the friction force between the inflatable bag and the well wall. At this time, the trapped person can be pulled out of the deep well by the upper related device.
The present invention is not limited to the above embodiments, and any person skilled in the art can make many modifications and equivalent variations by using the above-described structures and technical contents without departing from the scope of the present invention.
