Small tunnel air conveyor for earthquake rescue

Abstract

The invention relates to the technical field of earthquake rescue, and discloses a small tunnel air conveyor for earthquake rescue. The conveyor comprises a camera, one side of the camera is fixedly connected with an air delivery pipe, the other side of the air delivery pipe is fixedly connected with an air delivery device, the outer side of the air delivery pipe is movably connected with an outer cylinder in a sleeving mode, a spiral sliding way is movably connected between the air delivery pipe and the outer cylinder, and an outer supporting device is movably connected to the outer side of the outer cylinder. According to the conveyor, slide way blades start to drive the outer cylinder to be in a contraction state, then the air delivery device rushes gas into the position between the air delivery pipe and the outer cylinder, the slide way blades are rotated by half a period along outer protruding grooves under the action of gas flow to support the outer cylinder, the continuous slide way blades form a material slide way, similar spherical materials are put into a feeding opening and driven by the gas flow to enter a storing and taking groove along the spiral sliding way, and the problem of single function of an earthquake rescue air conveyor is solved.

Description

technical field [0001] The invention relates to the technical field of earthquake rescue, in particular to a small tunnel air conveyor for earthquake rescue. Background technique [0002] The small tunnel air conveyor for earthquake rescue is a kind of equipment that uses the controller to control the camera to take the pipeline through the gaps in the ruins to deliver oxygen to the trapped people. During the oxygen delivery process, aftershocks and other shaking may occur at any time, resulting in broken The stones press the delivery pipe, and the delivery of oxygen can relieve the hypoxia of the trapped people, but it also needs other materials. [0003] There are still some defects in the existing small-scale tunnel air conveyors for earthquake rescue: first, the air conveyor is used to deliver the oxygen needed by the trapped people, and its function is too single, what the trapped people need is not only oxygen but also survival Second, when there is shaking, the crush...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the use of the existing small tunnel air conveyor for earthquake rescue proposed in the background technology, the present invention provides a small tunnel air conveyor for earthquake rescue, which can transport other oxygen while transporting oxygen. The advantages of rescuing supplies and preventing the falling of crushed stones to squeeze the pipeline solve the technical problems raised in the above-mentioned background technology
