Abstract

APARATO DE CONTROL PARA UN LECHO QUE SE ENCUENTRA DEBAJO DEL AGUA QUE CONSTA DE UN SENSOR POR LO MENOS PARA QUE ESTE EN RELACION DE SEÑAL DE ALARMA CON DICHO LECHO, DE MODO QUE UN FLUJO SUFICIENTE DE AGUA ACTIVARA UNO DE LOS SENSORES ANTEDICHOS POR LO MENOS PARA QUE EMITA UNA SEÑAL DE ALARMA COMO MINIMO EN RESPUESTA A UNA EROSION CORRESPONDIENTE AL LECHO, ESTANDO UNO DE DICHOS SENSORES POR LO MENOS ADAPTADO PARA QUE ESTE EN MODO DESACTIVADO DURANTE LAS CONDICIONES DE FLUJO NORMALES; UN CIRCUITO PARA DICHO SENSOR POR LO MENOS. SE PUEDE ENTERRAR EN EL LECHO UNA RED DE SENSORES DESCENDENTE CUANDO SE DE UNA CONDICION DE FLUJO NORMAL PARA QUE ASI ESTE EN MODO DESACTIVADO. EL SENSOR PUEDE TENER UN BRAZO OSCILANTE (21) QUE TIENE UNA PRIMERA PARTE FINAL (22) PARA SOPORTAR EL BRAZO Y UNA SEGUNDA PARTE (23) QUE TIENE UNA CELDA SENSORA (25) EJ. UN INTERRUPTOR DE MERCURIO OMNIDIRECCIONAL. LA SEÑAL DE ALARMA PUEDE SER INDICATIVA DEL RIESGO DE COLAPSO DE UNA ESTRUCTURA HIDRAULICA, EJ. LA CIMENTACION DE UN PILAR DE PUENTE.
