The collection unit 102 may be subjected to a significant amount of fluid (ie, seawater) resistance during foraging, and weight in the air may also be applied when lifting marine organisms. Due to this, a tendon (not shown) acts to prevent the collector 102 from tearing.

In addition, the gaedae 1024 is to widen the ends of the wing net 127, and the frits line 131 and the connecting frits 133 are for collecting marine creatures widely through the collecting unit 102. . The chisel line 132 can be connected to the ship-shaped moving unit 101 while being connected to the frit line 131 and the connecting frit line 133, so that the collecting unit 102 by the moving unit 101 is pulled. can be used

Also, the moving unit 101 may wind or pull the connecting unit 103 to guide the collecting unit 102 onto the moving unit 101 . Here, the marine organisms collected in the collection unit 102 may be removed, and the collection unit 102 may be put back into the sea. Due to this, the marine life can be easily and continuously removed from the collecting unit 102, and the collecting unit 102 can be maintained in a state capable of collecting the marine life.

The thickness of the foot line 1021, the moxa line 1022, the net line 1023, the flagpole line 1025, the tendon, the pull line 131, the draw line 132, and the connecting pull line 133 is the resistance of marine organisms and fluids. , may be determined in consideration of weight in air. Preferably, the foot line 1021 , the moxibustion line 1022 , and the tendon are made of a non-stretchable wire rope, and the tendon may be a compound rope. When the moxibustion line 1022, the tendon, etc. is a wire rope, it can be slid when tied with a thread for connection with a net, so it can be overwound with a thread having a diameter of 3 mm. If the sole 1021 is too heavy and thin, pearls float during the anticipation of the collection unit 102 and thus the intended purpose cannot be achieved, so both the weight and the finished thickness should be considered. The pull line 131 and the connecting pull line 133 are made of a compound rope or a fiber rope to be in close contact with the seabed and sweep the sea floor to improve the scavenger effect, and the pull line 132 is made of a wire rope, and a collection unit ( 102) can sufficiently withstand the fluid resistance and friction resistance applied to it.

6 is a view illustrating a modification of the mesh 110 of another form in the collecting unit 102 of the marine life inflow prevention device 100 for the intake port of a nuclear power plant according to an embodiment of the present invention.

As shown in Fig. 6, each of the meshes 110 in the collecting unit 102 may be formed in a form in which four rod-shaped bases 110a are connected to form a knot 110b to form a predetermined opening. have. Here, each base 110a may include a pair of base members 110a' that may be spaced apart from each other. Receiving grooves 110' may be concavely formed in the first longitudinal cross-sections of the base members 110a' facing each other.

In addition, the mesh 110 may further include an elastic member (110c). The elastic member 110c may be formed in the form of a compression spring. In addition, the elastic member 110c may be inserted into the receiving groove 110' and fixed to the base members 110a', and the first longitudinal cross-sections of the base members 110a' may be in close contact with each other (FIG. 6). see (a)). Here, both ends of the elastic member 110c may be fixed to the inner longitudinal cross-section of the receiving groove 110', respectively.

On the other hand, when a load (for example, a load capable of breaking the base member 110a ′) is applied to the collection unit 102 or more due to marine life and seawater, the base members 110a ′ are spaced apart from each other while The elastic member 110c may be stretched (see FIG. 6(b)). Here, the elastic member 110c may maintain the base members 110a' in a connected state. When a load greater than the set value is applied to the collection unit 102 due to marine life and seawater, the elastic member 110c can prevent separation and damage of the base 110a and the size of the mesh 110 according to the load is changed can be

In addition, when the load applied to the collection unit 102 is reduced, and a load smaller than the set value is applied to the collection unit 102 , the elastic member 110c is contracted to its original shape, and the first longitudinal cross-sections of the base members 110a ′. By closely contacting each other, the base 110a can be restored to its original shape and the size of the mesh 110 can also be restored. Therefore, the collection unit 102 according to the present embodiment can have an increased lifespan by minimizing damage to the mesh 110 .

7 is a view showing the operation of another type of moxibustion cord 1022 in the collecting unit 102 of the marine life inflow prevention device 100 for the intake port of a nuclear power plant according to an embodiment of the present invention.

Each of the moxibustion cords 1022a is made of a deformable material (eg, a thin vinyl material, etc.), and may have an air space 1022a' therein. Here, the moxibustion (1022a) is connected to each other by an air guide pipe (1020), the air guide pipe (1020) may be connected to an air guide device (not shown) installed in the moving unit (101).

When the air induction device supplies air to the air space 1022a of the moxibustion 1022a through the air guide tube 1020, the amount of air in the air space 1022a' is increased so that the moxibustion 1022a can be gradually expanded ( See Fig. 7(a)). When the moxibustion (1022a) is in an expanded state, when the air induction device sucks in air and discharges it from the air space (1022a) of the moxibustion (1022a), the amount of air in the air space (1022a') is reduced, and the moxibustion (1022a) is It can be gradually contracted (see Fig. 7(b)).

Here, the weights 1022b positioned to be adjacent to each other in the moxibustion line 1022 may be positioned to face each other so as to have the same polarity. A repulsive force is applied between the weights 1022b, so that the weights 1022b are positioned to be spaced apart from each other, and the moxibustion line 1022 can be maintained in an untangled state.

In a state where the moxibustion line 1022 is located in the sea, air is supplied to the air space 1022a and the moxibustion 1022a is expanded to float on the surface of the sea (see Fig. 7(a)). On the other hand, the air is discharged from the air space (1022a), the moxibustion (1022a) can be contracted and sink below the surface of the sea of Uirae under the action of the moxibustion line (1022) and the weights (1022b) (see Fig. 7(b)) ). The buoyancy of the moxibustion (1022a) can be adjusted by the amount of air in the air space (1022a'). Due to this, the position of the collection unit 102 with respect to the sea level may be controlled by adjusting the buoyancy of the moxibustion (1022a).

In addition, the moxibustion line 1022 is located along the upper end of the entangled field wing 127a of the wing net 127, the upper end of the wing triangular net 129 and the second end of the ceiling net 125, and the weight 1022b) Due to the repulsive force between them, they can be kept in an unfolded state. Due to this, the wing net 127, the wing triangular net 129 and the ceiling net 125 may also be unfolded, and the collection unit 102 may be maintained in an unfolded state.
