Description
Technical field
The present invention relates to hose industrial circles, in particular to a kind of bellows and with the emergency of bellows
Conveying device.
Background technique
Military operation or field field are frequently run onto the situation of water intaking or On The Oil And Gas Transportation difficulty, especially need it is remote or
The case where higher position is fetched water.Since existing bellows is limited by structure, longest distance of stretch out and draw back is generally no greater than
8 times of hose original length are fetched water at a distance in field, need to carry the biggish hose of volume, inconvenient for use, occupied space
Greatly, weight is big, needs manually to withdraw after use, or is withdrawn by the winding of more bulky machine automatization, cannot achieve automatic
Recycling.
In addition, meet Sudden Geological Hazards succour underground trapped person, or chronically under closed blindage military activity when, need
To underground conveying water source, oxygen, nutrient solution and pump drainage underground pernicious gas etc..Existing bellows is under the operating condition, only
Two hoses can be set simultaneously, and one is used to convey required gas-liquid, another is for being discharged harmful gas-liquid.The then work of comb wiring
Make to need to repeat, twin flue occupies bigger space, can not quick communicatively upper and underground sealed environment.
Summary of the invention
The different types of gas-liquid of simultaneous transmission, and longer bellows scaling are unable to solve existing bellows
Compared with the technical problem that small, occupied space is big, inconvenient to use, the invention discloses a kind of bellows and with bellows
