Abstract
(EN)
The present invention relates to a small hydroelectric power generation device installed underwater and, more particularly, to a small hydroelectric power generation device installed underwater, wherein the device is connected to a platform floating on a water surface, an impeller is installed inside a submerged tube that is submerged underwater, the impeller is rotated by a flow pressure of a fluid that passes through the submerged tube, thereby driving a generator, and electric energy is accordingly generated. The technical gist of the present invention described above is a small hydroelectric power generation device installed underwater, comprising: a platform floating on a water surface; a submerged tube connected to the platform and submerged in water; an impeller installed inside the submerged tube and rotated by a flow pressure of a fluid occurring underwater; and a generator connected to the impeller outside the submerged tube so as to generate electricity by means of rotational force of the impeller, wherein the impeller comprises an upper boss having the shape of a disk that is convex upward, a driving shaft of the generator being connected to the upper boss; a lower boss having the shape of a disk that is convex downward, the lower boss being shaft-supported on the submerged tube; and a plurality of blades formed in wing shapes, the blades connecting peripheries of the upper and lower bosses at a predetermined interval in curved shapes.

La présente invention concerne plus particulièrement un petit dispositif de production d'énergie hydroélectrique qui est installé sous l'eau et qui est relié à une plateforme flottant sur une surface d'eau, et dans lequel une turbine est installée à l'intérieur d'un tube immergé qui est immergé sous l'eau. La turbine est entraînée en rotation par une pression d'écoulement d'un fluide qui passe à travers le tube immergé, entraînant ainsi un générateur, et de l'énergie électrique est ainsi générée. L'aspect technique de la présente invention décrit ci-dessus est un petit dispositif de production d'énergie hydroélectrique installé sous l'eau, comprenant : une plate-forme flottant sur une surface d'eau; un tube immergé relié à la plateforme et immergé dans l'eau; une turbine installée à l'intérieur du tube immergé et entraînée en rotation par une pression d'écoulement d'un fluide se produisant sous l'eau; et un générateur relié à la turbine à l'extérieur du tube immergé de façon à produire de l'électricité au moyen d'une force de rotation de la turbine. La turbine comprend un bossage supérieur ayant la forme d'un disque qui est convexe vers le haut, un arbre d'entraînement du générateur est relié au bossage supérieur; un bossage inférieur ayant la forme d'un disque qui est convexe vers le bas, le bossage inférieur étant supporté par un arbre sur le tube immergé; et une pluralité d'aubes formées dans des formes d'aile, les aubes reliant les périphéries des bossages supérieur et inférieur à un intervalle prédéterminé dans des formes incurvées.
