Abstract
The present invention relates to a hydroelectric power generator using ebb and flow of seawater. More particularly, the hydroelectric power generator is able to continuously generate power through high tide and low tide created according to a tidal difference that continuously occurs, while being submerged in seawater, using a marine current that flows fast. The hydroelectric power generator is also able to utilize eco-friendly energy that does not require a reservoir by adjusting the amount of inflow of seawater and to be installed at various places, while being varied in size, as necessary.

A hydroelectric power generator using ebb and flow of seawater, the hydroelectric power generator comprising:
- a flood power generation unit (100) including:
- a lower flow guide unit (30) disposed between side guides (70) and having a blade guide (33) at a front end of an upper flow guide (32);
- a turbine (10) disposed on a turbine shaft (11) over the lower flow guide unit (30), having reinforcing grooves (13) formed in blade seats (12) formed on an outer side of the turbine such that reinforcing portions (23) of blades (20) fit to two sides, and having fixed shafts (21) disposed through the blade seats (12);
- the blades (20) fitted on the fixed shafts (21) passing through the turbine (10) in the blade seats (12) to be deployed by seawater and rotate the turbine (10);
- and an upper flow guide unit (40) disposed over the lower flow guide unit (30) between the side guides (70) and having a power generation guide (41) in which the blades (20) on the outer side of the turbine (10) are deployed and moved;
- and
- an ebb power generation unit (200) including:
- an upper flow guide unit (30a) disposed between side guides (70a) and having a blade guide (33a) at a front end of an upper flow guide (32a);
- a turbine (10) disposed on a turbine shaft (11) under the upper flow guide unit (30a), having reinforcing grooves (13) formed in blade seats (12) formed on an outer side of the turbine such that reinforcing portions (23) of blades (20) fit to two sides, and having fixed shafts (21) disposed through the blade seats (12);
- the blades (20) fitted on the fixed shafts (21) disposed through the turbine (10) in the blade seats (12) to be deployed and rotate the turbine (10) by seawater;
- and a lower flow guide unit (40a) disposed under the upper flow guide unit (30a) between the side guides (70a) and having a power generation guide (41a) in which the blades (20) on the outer side of the turbine (10) are deployed and moved,
- wherein the lower flow guide unit (30) has a lower guide (31) having a streamlined bottom, a blade guide (33) where the turbine (10) is disposed is formed at a front end of a flow guide (32) formed at a front upper portion, and a lower drainage (34) horizontally forming a drain space (45) is formed at a front end of the blade guide (33), and
- the blades (20) are fitted on the fixed shafts (21), are rotatably coupled at both sides by bushings (22), have an outer front end protruding from the blade seats (12), and have the reinforcing portion (23) fitting to two sides of the reinforcing grooves (13).
