11 is a view showing the configuration of the wing unit provided in Figures 1 to 10, Figure 12 is a view showing a schematic configuration of the wing frame shown in Figure 11, Figure 13 is the operating principle of the wing shown in FIG. It is a figure which shows, and FIG. 14 is a figure which shows the structure of the rolled blade of the power generation device which consists of the buoyancy body which concerns on this invention.

11 and 12, the wing portions 40, 70 of the power generation device made of a buoyancy body according to the present invention, a plurality of wing frame 41 made of a multi-stage grid mesh structure, and the wing frame 41 It is configured to include a plurality of rectangular wings 42 coupled to). In this case, a foreign matter film 43 having a lattice mesh structure formed in multiple stages may be further provided around the outer surfaces of the wing parts 40 and 70. The lattice spacing of the foreign material film 43 may be less dense than the lattice spacing of the wing frame 41. The wing portion having the above configuration may be divided into a first wing portion 40 provided on the lower portion of the rotating body 30 and a second wing portion 70 provided on the outer circumferential surface of the diving force body 20.

In this case, the wing 42 provided in the first wing portion 40 and the wing 42 provided in the second wing portion 70 are coupled to opposite surfaces of the wing frame 41 so as to be coupled to the first surface. The wing 40 and the second wing 70 is rotated in the opposite direction to each other. That is, if the wing 42 provided in the first wing portion 40 is coupled to one side of the wing frame 41 (for example, the left side when viewed from the outside of the wing frame as shown in the figure), The wing 42 provided in the second wing unit 70 may be provided on the other side (for example, the right side when viewed from the outside of the wing frame). Since the other configurations except for the coupling direction of the wing 42 of the 1st wing part 40 and the 2nd wing part 70 are the same, it demonstrates below by taking the 1st wing part 40 as an example.

The wing 42 may be made of a material such as metal or plastic. At this time, the wing 42 is rotatably coupled to one side of one side of the wing frame 41 described above, the other three side edges may be spaced apart from the wing frame 41. As an example of the coupling form of the wing 42 and the wing frame 41, the configuration of the hinge can be used.

In addition, the wing 42 may be made of a waterproof material that can be folded and rolled upright, and the upper end corner portion of the wing 42, such as helium pocket to prevent the wing 42 from sagging down. Upright reinforcement means 85 may be provided (see FIG. 14).

In the configuration as described above, when the horizontal flow of seawater in one direction is made, the blade 42 attached to the surface of the wing frame 41 located in the direction of the horizontal flow of the seawater is subjected to the flow pressure of the seawater It is in close contact with the surface of the grid structure formed as the force is transmitted to the wing frame 41 to rotate the rotating body 30 described above (see Fig. 13).

Thus, in addition to the rotating body 30 rotated by the flow pressure of the sea water, the blade 42 attached to the wing frame 41 is also rotated to move to the opposite position. As a result of the movement, the blade 42 is located on the opposite side of the wing frame 41 located in the direction of the flow of sea water, so that the horizontally flowing sea water just passes between the grid structure formed in multiple stages, Due to the pressure of the sea water, the three side surfaces of the wing 42 are separated from the lattice-shaped structure surface formed by the multi-stage of the wing frame 41, so as not to disturb the flow of sea water. As a result, the rotor 30 always rotates in a constant direction regardless of the horizontal flow of seawater in any direction. When the wings 42 provided on the first wing portion 40 and the second wing portion 70 are provided on opposite surfaces of the wing frame 41, the first wing portion 40 and the second wing portion 42 are provided. The wings 70 are always rotated in opposite directions regardless of the flow direction of the sea water.

The wing 42 may be composed of a fixed wing (not shown) and a roll-shaped wing 80 that are directly attached and fixed to the wing frame 41 made of a lattice network structure. The scroll type blade 80 illustrated in FIG. 14 is configured to be rollable in the form of a roll, so that when the horizontal flow rate of seawater is fast, its length can be shortened, and when its speed is slow, its length can be adjusted. Therefore, the rotational speed of the rotor 30 and the submersible buoyancy body 20 can always be automatically and automatically adjusted by the reel type blade 80. In this case, the rolled wing 80 may be partially installed only on a part of the first wing 40 and the second wing 70.

The rolled wing 80 may include a wing curling shaft 81, a wing protrusion 84, and a wing feather 82. The wing curling shaft 81 is formed in a rod shape, and the wing projection 84 is provided on the wing curling shaft 81. The wing protrusions 84 are preferably provided with a pair (two) on both sides of the wing curling shaft 81, as shown in the figure. In addition, each of the pair of wing projections provided on both sides may be provided with one or more wing projections 84 radially.

The wing feather 82 is made of a waterproof material that can be folded and curled, but can be upright. One edge thereof is coupled to the wing curling shaft 81, and has a plurality of insertion holes in the same line as the wing protrusion 84 described above. 83) is perforated. The wing protrusion 84 is radially disposed on the wing curling shaft 81 to be inserted into the insertion hole 83, and may be formed in a cramped shape. As a result, the roll-shaped wings 80 can be smoothly carried out. The rolled wing 80 is configured to be detachable to the first wing 40 and the second wing 70, to facilitate installation and repair. Thus, when the wing curling shaft 81 is rotated in one direction, the wing protrusions 84 are inserted into the insertion holes 83, and the wing feathers 82 are dried on the wing curling shafts 81, resulting in short wing blades 82. When the wing curling shaft 81 is rotated in the opposite direction, the wing feather 82 rolled up on the wing curling shaft 81 is released, and as a result, the wing feather 82 is lengthened. Therefore, when the wing feather 82 is short, the wing frame 41 blocked by the wing feather 82 is reduced, so that the rotation of the wing portion is slowed down. 41) increases, and the wing turns faster.

As a result, the first wing portion 40 and the second wing portion 70 is partially composed of a fixed wing (not shown) and the other portion is composed of a roll-shaped wing (80), while appropriately responding to the speed of sea water It can be driven.

That is, the outer contact fixing module 700 is formed of a trapezoidal hexahedron so as to occupy each through-hole inner side surface 301 of the rotating body 30 and both corner portions thereof at the same time.

In this case, the outer close contact fixing module 700 is evenly attached to each other to avoid the interference between the trapezoidal cubes. For example, each outer side (one side, two side, three side, four side, five side, six side) of the buoyancy body extension shaft outer bearing housing 352 is divided into four equal parts from the top to the bottom (A position, B position). , C position, and D position), the first, third, and fifth surfaces of the buoyant body shaft outer bearing housing 352 are located at positions A, C, and B, D on surfaces 2, 4, and 6, respectively. Outer contact fixing module 700 is installed in the position to avoid interference with each other. Subsequently, when the heights of the rotor 31 and the stator 21 coincide with each other, the automatic sensing means (not shown) detecting the same moves the outer contact fixing module 700 toward the inner side surface 301 of the through hole of the rotating body. It is fixed in close contact with the rotor 30.

It is installed to extend in the), and then closely coupled to the subsea fixed shaft 60 side and is completely coupled and fixed to the subsea fixed shaft 60. That is, the inner close contact fixing module 800 surrounds each outer surface and both corner portions of the subsea fixing shaft 60 at the same time, and has a form capable of closely contacting each other.

In this case, the inner close contact fixing module 800 is fixed after being completely adhered to the outer surface of the subsea fixing shaft 60 in the same manner as the configuration of the outer close fixing module 700 described above.
