The hoist 30 is disposed below the semi-submerged platform 10 having a built-in wind power and algae and ocean current generating device, and the algae and ocean current turbine blade shaft 77 and the rotary energy transmission shaft 78 are connected to the shaft 22 ) And can be steered to achieve maximum power generation capability by adjusting the wind direction and the wind direction in a vertical direction by a winch specially applied on a semi-submerged platform (10) incorporating wind turbines and algae generators of this type Up or down.

At this time, the alga and the current turbine blade shaft 77 and the rotation energy transmission shaft 78 are located in the shaft 22.

In particular, as can be seen in FIG. 7, according to the present invention, each shaft is provided with a guiding system including a grate-type rack 25, which is connected to the shaft 22.

In accordance with the present invention, it is further advantageous if the shaft 22 is protected by a guide system, such as a rack 25, in order to prevent the shaft 22 from rising, preventing the load from moving, and optimizing the use of the shaft.

The turbine blade shaft 77 and the rotation energy transmission shaft 78 are easily lifted from the inside of the shaft 22 and the inside of the shaft 22 is filled with the alga and the current turbine blade shaft 77 and the rotation It is advantageous, in accordance with the present invention, that the shaft 22 can be opened from the top (fully open) or partially open from the top (fully open) in order to easily position the energy transfer shaft 78 .

The depth of the shaft 22 measured from the main deck 21 of the semi-submerged platform 10 incorporating wind and algae and ocean current generators is determined by the depth of the shaft 22 and the current and turbine blade axis 77, If it is projected onto the main deck at a position where the tidal current and the turbine blade axis 77 and the rotational energy transmission axis 78 are disposed inside the shaft 22 so as to be substantially smaller than the length of the energy transmission shaft 78, Do.

This makes it easy to connect the tidal turbine blade shaft 77 and the upper end of the rotary energy transmission shaft 78 to the power generator and the shaft 22 is easily connected to the winch 30, It becomes relatively easy to access.

The entirety of the semi-submerged platform 10 in which the algae to be accommodated in the inside of the shaft 22 and the excessive length of the airstream power turbine blade shaft 77 and the rotational energy transmission shaft 78 are built into the wind power, Can be as long as desired except that it adversely affects the stability of the device.

The algae and the current turbine blade shaft 77 and the rotary energy transfer shaft 78 disposed inside the shaft 22 are protected from damage to the algae and the current turbine blade shaft 77 and the rotary energy transfer shaft 78, 78 protrude above the main deck, protection means, such as railings or bumper systems, are provided around the shaft opening on the main deck 21 so that the algae and airstream turbine blade shaft 77, If the transmission shaft 78 is projected onto the main deck, it is advantageous if the projecting end is protected against mechanical shocks such as an impact from the outside.

For example, damage due to parts of the vehicle or the hoisting equipment moving back and forth across the main deck 21 can be prevented.

The scope of the present invention is defined by the appended claims rather than by the embodiments described above, and those skilled in the art will understand that various changes and modifications may be made without departing from the scope of the appended claims. It is self-evident.
