FIG. 3 is a view showing an operation of a magnetic field generating unit after penetration of a suction file anchor according to an embodiment of the present invention. FIG.

As shown in FIG. 1, the suction file 100 may be opened at the lower end, and a sucker pump (not shown) may be connected to the upper end of the suction file 100. As shown in FIG. 2, the suction file 100 can be introduced into the seabed surface as the pressure inside the suction file 100 changes through the suction pump. At this time, the magnetic field generator 200 does not operate so that the suction file 100 can be smoothly penetrated.

As shown in FIG. 3, the suction file 100 may include a magnetic body M1, and after the penetration of the ground G, the magnetic body M1 may be magnetized through the magnetic field generating unit 200. FIG. The magnetic body M1 of the suction pile 100 is magnetized after it is intruded into the ground, so that it can be coupled with the magnetic body M2 of the ground, so that the supporting force against the ground can be improved.

The magnetic field generating unit 200 is coupled to the suction file 100 and can magnetize the magnetic body M1 through contact with the magnetic body M1 of the suction file 100. [

The magnetic field generator 200 may include a permanent magnet 210. The permanent magnet 210 may be rotatably coupled to the suction file 100. The permanent magnet 210 can selectively magnetize the magnetic body M1 by selectively contacting the magnetic body M1 of the suction pile 100 according to the rotation of the shaft.

1, the permanent magnet 210 is disposed on the space 230 in a state in which the permanent magnet 210 is not in contact with the magnetic body M1, so that the magnetic body M1 of the suction pile 100, Can be minimized. As shown in FIG. 3, when the suction pile 100 is introduced into the ground G through the suction pump as shown in FIG. 2, the permanent magnet 210 is rotated axially to come into contact with the magnetic body M1 to magnetize the magnetic body M1 .

The permanent magnet 210 has an N pole and an S pole, and generates its own magnetic field. The permanent magnet 210 is brought into contact with the magnetic body M1 and the magnetic body M1 which is in contact with the N pole and the S pole of the permanent magnet respectively is exposed to the magnetic field.

Before being exposed to the magnetic field, the magnetic moment of the electrons of the magnetic body M1 is directed in an arbitrary direction. When a magnetic field is applied to the magnetic body M1 through the permanent magnet 210, the magnetic moment of the electrons is simultaneously directed along the magnetic field to cause magnetization.

Since the magnetization of the magnetic body M1 is proportional to the intensity of the magnetic field, a plurality of permanent magnets 210 can be used to generate a stronger magnetic field. The magnetic field generator 200 can efficiently magnetize the entire magnetic body M1 of the suction file 100 by disposing a plurality of magnetic field generating units 200 along the circumference of the suction file 100. [

The suction file anchor according to the present embodiment magnetizes the magnetic body M1 of the suction pile 100 through the magnetic field generating part 200, that is, the permanent magnet 210, It is possible to improve the shear strength of the surrounding ground of the suction pile 100. [0060] That is, as shown in Fig. 3, the supporting force of the suction file 100 with respect to the ground G can be improved.

As shown in FIG. 1, the coupling body 220 is rotatably coupled to the suction pawl 100 and is capable of coupling the permanent magnet 210 to at least one surface thereof. As the engaging body 220 is rotated on the suction pawl 100, the permanent magnet 210 can be selectively brought into contact with the suction pawl 100.

The coupling body 220 may be formed in a disc shape and may be rotatably coupled to the suction pail 100 on the basis of a rotation shaft (not shown) passing through the center.

The motor unit is a device for providing a rotational force to the engaging body 220, and can rotate the engaging body 220 axially. The motor unit may rotate the coupling body 220 to allow the permanent magnet 210 to contact the suction pile 100 after the suction pile 100 is penetrated.

The motor unit is coupled to the rotating shaft of the engaging body 220 to rotate the engaging body 220 directly. The permanent magnet 210 is interlocked with the rotating shaft of the engaging body 220, can do. In addition, the motor unit is engaged with a gear (not shown) formed around the coupling body 220, thereby rotating the coupling body 220.

The suction file anchor according to the present embodiment may further include a penetration detection sensor 300 for detecting the intrusion state of the suction file 100 and operating the motor after the intrusion of the suction file 100.

2, the intrusion detection sensor 300 may be installed inside the suction file 100 to sense a collision between the suction file 100 and the ground G to detect the intrusion state of the suction file 100 .

The intrusion detection sensor 300 may be electrically connected to the motor unit to provide a penetration completion signal of the suction file 100 to the motor unit and the motor unit to which the signal is supplied may rotate the engagement body 220. This makes it possible to magnetize the magnetic body M1 of the suction file 100 by bringing the permanent magnet 210 into contact with the magnetic body M1 after the suction file 100 is intro- duced.

In the present embodiment, as the engaging body 220 is rotated on the suction file 100, the permanent magnet 210 is brought into contact with the suction file 100, but the present invention is not limited thereto.
