AI Technical Summary

Problems solved by technology

Such a huge traction force is unbearable for those in distress, and it will cause the body to be severed and die immediately
If it is towed obliquely, the dragging force will be greater, and the person in distress cannot bear it.

Embodiment Construction

[0019] see figure 1 , in a certain wetland 1, a certain person 2 is in distress, and sinks in the mud 11 below the chest.

[0020] Since there is no gap between the person in distress 2 and the silt, when the person in distress 2 leaves the silt, he needs to overcome his own gravity F1, viscous force F2, mud pressure F3, and the space where the person in distress will leave, and the drag formed by the lack of fluid material filling in time Negative pressure resistance F4.

[0021] see figure 2 , the rescuer 3 came to the rescue, and the approaching rescuer 31 first fixed the rope 4 on the person in distress 2, handed it over to the rescuer 32 in the solid zone 12 to tow, and then used the hard guidance of the mud trap lifesaving rescue device 5 The pipe 51 will be inserted below the person in distress, and communicated with the high-pressure fluid device 52 by the connecting conduit 53, inject foam 6 close to the foot of the person in distress, and slowly drag the person in...

Abstract

The invention relates to a mud sinking lifesaving salvation method and device and relates to lifesaving salvation. The mud sinking lifesaving salvation method helps people, animals and objects (collectively called person in distress as below) which sink in sludge to break away from the sludge. Fluid matters are injected between the person in distress and the sludge from the position below the person in distress, a sufficient gap is formed to reduce resistance such as dragging negative pressure, and the mud sinking lifesaving salvation device for achieving the method is provided.

Description

technical field [0001] The mud-sink life-saving rescue method of the present invention relates to life-saving rescue, and is a method for helping people, animals and objects (hereinafter collectively referred to as persons in distress) trapped in mud to get out of mud sink; the mud-sink life-saving device corresponding to this method belongs to The life-saving rescue equipment is used for the implementation of life-saving rescue in mud. Background technique [0002] Mud sinking is a kind of threat to people's life and property. In permanent wetlands (such as rivers, lakes, seas and swamps) and temporary wetlands (after flash floods), there are often children and even adults who get stuck in mud, and livestock, wild animals and even objects also get stuck in mud from time to time. [0003] The current life-saving rescue for mud subsidence accidents usually relies on rescuers to get as close as possible, directly or indirectly dragging with ropes, to help the victims get out ...
