Safety Fish Way

Abstract

A safe fish guide path structure includes a horizontal tube having an intake and exhaust valve for controlling levels of air having lower viscosity than water. The horizontal tube is equipped with a transparent window at both sides about the intake and exhaust valve. The horizontal tube is installed at a weir or a bank. An inclined tube extends horizontally from both sides of the horizontal tube. An extended tube extends horizontally from an end portion of the inclined tube. An inlet tube extends from an end portion of the extended tube toward an upper side, while communicating with the extended tube, with water flowing through the inlet tube. A cover has an insertion groove at one side into which the extended tube is inserted, and a cut-away groove at the other side for water to flow through the cutaway groove.

1 . A safe fish guide path structure, comprising:
 a horizontal tube ( 10 ) which is formed of an intake and exhaust valve controlling the water level in the interior depending on the increase and decrease of occupied air in the tube, with the horizontal tube generally being installed at a weir or a bank D;   an inclined tube ( 20 ) which is extended from both end portions of the horizontal tube  10 ) to the lower side along an outer side surface of the weir or the bank (D), while communicating with the horizontal tube ( 10 );   an extension tube ( 30 ) which is horizontally extended from the end portion of the inclined tube ( 20 ), while communicating with the inclined tube ( 20 ); and   an inlet tube ( 40 ) which is upwardly extended from the end portion of the extended tube ( 30 ) for a communication with the extended tube ( 30 ), thus allowing the water of the river or the stream to come in or go out,   with a light transparency window ( 12 ) is provided on the upper surface of the horizontal tube ( 10 ) thus passing sunlight through.   
     
     
         2 . (canceled) 
     
     
         3 . The structure of  claim 1 , wherein said horizontal tube ( 10 ) has a through hole ( 13 ) at its lower surface, and a chamber ( 14 ) is formed at a lower side of the through hole ( 13 ), so fish can swim. 
     
     
         4 . The structure of  claim 3 , wherein a see through window ( 11 ) is installed at a front side of the horizontal tube ( 10 ) and at a front side of the chamber ( 14 ), respectively, thus checking out the levels of the water in the horizontal tube ( 10 ) and the chamber ( 14 ). 
     
     
         5 . The structure of  claim 1 , wherein a cover ( 50 ) is installed at an upper side of the inlet tube ( 40 ), and the cover ( 50 ) has an insertion groove ( 51 ) at its one side for the extended tube ( 30 ) to be inserted into the same, and has a cut-away groove ( 52 ) at its other side, so the water of the river or the stream flows through the inlet tube ( 40 ).
