Hereinafter, an embodiment of a suction anchor according to the present invention will be described in detail with reference to the accompanying drawings. Referring to the accompanying drawings, the same or corresponding elements are denoted by the same reference numerals, Is omitted.

FIG. 1 and FIG. 2 are views showing a suction anchor according to an embodiment of the present invention, and FIG. 3 is a view showing a penetration of a suction anchor according to an embodiment of the present invention. FIG. 4 is a view showing a state in which a penetrating derivative of a suction anchor according to an embodiment of the present invention induces penetration. FIG. 5 is a bottom view of a suction anchor according to an embodiment of the present invention.

Referring to FIGS. 1 and 2, a suction anchor 10 according to an embodiment of the present invention includes a pile 100 and a penetrating derivative 200. Referring to FIG. 3, the intrusion derivative 200 may include a rotating frame 211, a weight portion 220, a guide frame 230, an extension portion 240, and a cover 250.

The pile 100 is a columnar body having a hollow inside, one end open, and the other end closed, and may be formed in various shapes such as a cylindrical shape or a square column shape. At the other end surface of the pile 100, a suction pump 110 for depressurizing the hollow can be installed. The suction pump 110 may be set to operate when the file 100 is set to a predetermined depth on the sea floor. By operation of the suction pump 110, air in the hollow and water are pumped to the outside, and the pile 100 can be penetrated into the undersurface due to the difference in pressure between inside and outside.

The intrusive derivative 200 is formed at one end of the pile 100 to induce the penetration of the pile 100. The connection pillar 120 may be interposed between one end of the pile 100 and the penetration guide 200.

The penetrating derivatives 200 can be formed in plural around one end of the pile 100 (see FIG. 5). When a plurality of penetration derivatives 200 are formed, the tube input of the pile 100 can be further improved, and the shrinkage or relaxation of the plurality of penetration derivatives 200 occurs in a plurality of the same way. In this case, a plurality of connecting columns 120 are also formed.

The penetrating derivative 200 shrinks and relaxes in the longitudinal direction of the pile 100 (the advancing direction of the pile 100) to advance the pile 100. That is, when the intruding derivative 200 is relaxed as shown in FIG. 1, the intruding derivative 200 advances into the undersurface, and when the intruding derivative 200 contracts as shown in FIG. 2, (100) is pulled by the penetrating derivative (200) and proceeds to the inside of the sea floor. The penetrating derivative 200 can cause the shrinkage and relaxation to occur either singly or continuously so as to advance the pile 100 either singly or continuously.

On the other hand, the operation linkage between the intrusion derivative 200 and the suction pump 110 can be variously set. After operation of the suction pump 110, the intrusive derivative 200 may operate, or both may operate simultaneously. Further, the suction pump 110 may operate after the operation of the intrusion derivative 200.

3 and 4, the penetration guide 200 may include a constriction 210, a weight 220, a guide frame 230, and an extension 240.

The contraction relaxation unit 210 includes a rotation frame 211 composed of a pair of frames. The pivot frame 211 is arranged long in the longitudinal direction of the file 100. The pair of frames of the pivot frame 211 cross each other to form an 'X' shape. A pair of frames rotate in opposite directions about an intersection point.

The contraction relaxation unit 210 can be contracted or relaxed while the angle formed by the pair of frames changes. That is, when the angle a (the upper angle of the 'X' character) formed by the pair of frames in FIG. 4 is increased, the contraction relaxation unit 210 contracts, and when the contraction relaxation unit 210 becomes smaller, the contraction relaxation unit 210 relaxes.

The shrinkage relaxation unit 210 may include a plurality of rotation frames 211. That is, the contraction relaxation unit 210 may be composed of a plurality of modules with the pivot frame (pair of frames) 211 serving as a basic module. The plurality of rotation frames 211 are continuously arranged in the longitudinal direction of the file 100, and the adjacent rotation frames 211 can be hinged to each other. Here, "neighboring pivot frames 211 are hinged to each other" means that the frames constituting the pivot frame 211 are hinged to each other in the longitudinal direction of the file 100.

When the shrinkage relaxation unit 210 includes a plurality of rotation frames 211, the shrinkage relaxation unit 210 has a shape in which the X-axis is continuously connected vertically. The rotation of the plurality of rotation frames 211 is linked. In other words, all the pivoting frames 211 rotate simultaneously to have the same shape. In terms of angles, the angles a of the respective frames are both increasing or decreasing at the same time. When a plurality of pivoting frames 211 are formed, the difference between the length when the shrinkage relaxation unit 210 is shrunk and the length when the shrinkage relaxation unit 210 is relaxed becomes large, so that the progress distance at the time of shrinkage relaxation becomes large.

The weight portion 220 is coupled to the end of the constriction relaxation portion 210 and leads to the penetration of the penetration derivative 200 when the constriction relaxation portion 210 is relaxed and is fixed at that position when the constriction relaxation portion 210 is contracted . At this time, the fixed weight portion 220 pulls the pile 100 downward. On the other hand, the weight portion 220 may be sharp so as to be easily penetrated into the sea floor.

The guide frame 230 is formed at both ends of the shrinking relaxation part 210 to guide the movement of the end of the rotation frame 211. The guide frame 230 is formed between the pile 100 (or the connecting pillar 120) and the shrinkage relaxation portion 210 and between the shrinkage relaxation portion 210 and the weight portion 220, respectively.

The end of each frame of the pivoting frame 211 is horizontally moved, and the guide frame 230 guides the horizontal movement. The coupling portion C is formed at an end of each frame of the rotation frame 211. The coupling portion C is coupled to the opening region 231 of the guide frame 230. The coupling portion C is coupled to the guide frame 230 230 on the opening area 231 of the first and second electrodes 230, 230. Here, 'horizontal' is understood as a horizontal direction when the progress direction of the file 100 is set to the vertical direction, and means a direction perpendicular to the progress direction of the file 100.

The extension part 240 is formed in the weight part 220 and is a part that can be extended to protrude outside the weight part 220 and strengthens the supporting force of the weight part 220. Referring to FIG. 3, the extension 240 is formed with a pointed end, but its shape is not limited to that shown and may vary. The extension portion 240 is seated in the weight portion 220 and protrudes out as necessary. It is advantageous for the extension part 240 to be free from penetration when the shrinkage relaxation part 210 is relaxed and the weight part 220 is intruded. When the shrinkage relaxation part 210 contracts, (100).

4, in the relaxed state of the contractile relaxation part 210, the extension part 240 is seated inside the weight part 220. As shown in FIG. The extension portion 240 protrudes to support the weight portion 220 before the contraction relaxation portion 210 starts to contract to increase the supporting force of the weight portion 220. Thereby, when the weight portion 220 is fixed, the shrink relaxation portion 210 contracts to pull the file 100. [

Meanwhile, the cover 250 covers the shrinking relaxation unit 210 to protect the shrinkage relaxation unit 210. The cover 250 contracts and relaxes with contraction and relaxation of the contractile relaxation portion 210. Accordingly, if the cover 250 is formed of a material that is not corroded or a flexible material, the material of the cover 250 may be variously used. The cover 250 can cover the guide frame 230 as well as the shrinkage relaxation unit 210.

As described above, according to the suction anchor according to the embodiment of the present invention, the input of the suction anchor can be improved by the action of the shrinkage and relaxation of the penetrating derivative.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
