Precaution hose

Abstract

A precaution hose is a hollow cylindrical body made of waterproof material with a length thereof being cut as the actual need. Two seal plates are attached to the two ends of the cylindrical body respectively. A valve is mounted to the cylindrical body. The seal plates are touched to the edges of a gap thereof tightly and the cylindrical body is filled with the liquid till being full completely so that a lower part of the cylindrical body can press against the floor due to an inner liquid pressure to keep the floodwater out.

What is claimed is:  
     
         1 . A precaution hose, comprising 
 a hollow cylindrical body, being made of waterproof material and having a length being cut as actual need, providing two ends;    two seal plates, corresponding to the two ends respectively, and each of the seal plates being sealed to each of the two ends; and    a valve, being mounted to the hollow cylindrical body; 
 wherein, the seal plates are touched to edges of a gap tightly and the cylindrical body is filled with the liquid till being full completely so that a lower part of the cylindrical body can press against the floor due to an inner liquid pressure and the flood can be kept out.  
   
     
     
         2 . The precaution hose according to  claim 1 , wherein the cylindrical body at the lower part thereof is provided with a spherical surface and a cross section of the cylindrical body is round or ellipse.  
     
     
         3 . The precaution hose according to  claim 1 , wherein the cylindrical body is made of high molecular material such as the rubber, the plastics, or the equivalent, and an inner surface thereof may be provided with a reinforced layer to strengthen a structural stress thereof.  
     
     
         4 . The precaution hose according to  claim 1 , wherein an outer surface of the cylindrical body may be provided with a protect layer to avoid being broken.  
     
     
         5 . The precaution hose according to  claim 1 , further comprises at least a stopper at the lower part near an inner lateral side thereof for supporting the cylindrical hose.  
     
     
         6 . The precaution hose according to  claim 1 , wherein the seal plates each may join a support piece respectively for facilitating the extension and retraction of the cylindrical body.  
     
     
         7 . The precaution hose according to  claim 1 , wherein the cylindrical body is laid in a channel flute and the channel flute provides a plurality of fastening pieces to fix the cylindrical body.  
     
     
         8 . The precaution hose according to  claim 7 , wherein the cylindrical body at both ends thereof at least provides two valves, and one of the two valves is a unidirectional inlet valve and another one of the two valves is a unidirectional outlet.  
     
     
         9 . The precaution hose according to  claim 8 , wherein the unidirectional inlet valve and the unidirectional outlet valve can connect a pump respectively.  
     
     
         10 . The precaution hose according to  claim 7 , wherein the channel flute at two opposite inner walls can provide a resilient projection respectively at a top thereof to occur friction so as to form a liquid seal.  
     
     
         11 . The precaution hose according to  claim 7 , wherein a cover is hinged to the channel flute at a lateral upper part thereof so that the cove can be in a state of opening or close in accordance with the liquid in the cylindrical body.
