Tent with a flood alarm

Abstract

A speaker which is fixed to the frame with a fixing bracket and a power supply connected with the speaker and generating electricity with the standard reduction potential of the oxidation-reduction reaction and a sensor connected with the power supply and has a sensing paper which moves electrons by absorbing water and a fixing ball attached at an aspect of the sensor and available to regulating its length inside of the tent which is composed of a frame and an outer cover that covers the frame. Because of its good portability and simplicity to setting, it is expected that explosive sales for preparing flood when campers visit valleys or flooding risk regions.

What is claimed is: 
     
         1 . A tent having a speaker which is fixed to the frame with a fixing bracket and a power supply connected with the speaker and generating electricity with the standard reduction potential of the oxidation-reduction reaction and a sensor connected with the power supply and has a sensing paper which moves electrons by absorbing water and a fixing ball attached at an aspect of the sensor and available to regulating its length inside of the tent which is composed of a frame and an outer cover that covers the frame. 
     
     
         2 . The tent according to  claim 1 , wherein the fixing ball is composed of a piece shaped spur which fixes to rear first and bending ropes which fixes second. 
     
     
         3 . The tent according to  claim 1 , wherein the power supply of the sensor has a copper plate of (+) pole and a sensing paper which includes copper chloride on the (+) pole and on the sensing paper there is a magnesium plate of (−) pole. 
     
     
         4 . The tent according to  claim 1 , wherein the fixing bracket is made of elastic materials and it has the fixing ball whose radius is same with that of the circled frame and an incision part whose radius of side is smaller than that of the frame is inserted by pressure with the frame.
