[0024] Please refer to the accompanying Figure 1 to the accompanying Figure 2 The utility model discloses a ship fixing device, be applicable to the fixing of shallow sea area ship, including the support 2 of detachable connection on the ship body 1 end part, to facilitate the position of ship fixing device is adjusted. The support 2 is fixedly connected with the lifting mechanism 3 and the support platform 4 that outwardly extends and sets, be equipped with the through hole 41 on the support platform 4, the through hole 41 is crossed for the column 5, the column 5 is configured as when inserting the seabed, through self -gravity and inserts, at this time, the top end of column 5 is located above the upper surface of through hole 41, to prepare for the pullout of subsequent column 5. The column 5 is configured as when pulling out the seabed, through lifting mechanism 3 and pulls out, specifically: lifting mechanism 3 is connected with column 5 through connecting piece 8, to drive column 5 and pull out the seabed. It can be understood that in the embodiment, its column 5 when inserting the seabed, only through self -gravity can be directly inserted in the seabed, in this way, not only realizes the fixing of ship, also simplifies the insertion process of column 5, and then improves the pile of existing ship when inserting the seabed needs the driving mechanism to complete, leading to the insertion process of pile exists the technical problem of relatively complicated.

[0025] Preferably, the number of ship fixing devices is two, and the two ship fixing devices are symmetrically arranged on the two end portions of the ship body 1, so that the overall stress of the ship body 1 is balanced.

[0026] Please refer to the accompanying Figure 1 to the accompanying Figure 2 In one preferred embodiment, the inner wall side of the through hole 41 is provided with a sliding bearing, which reduces the frictional resistance and makes the insertion and pullout process of the column 5 more stable and lower in energy consumption. The bottom end of the column 5 is an insertion end 51, which is in the shape of an inverted triangle, so that the column 5 can be quickly inserted into the seabed. However, those skilled in the art should understand that in other embodiments, the shape of the insertion end 51 can also be quadrilateral or pentagonal, and the utility model does not make specific limitations.

[0027] Please refer to the accompanying Figure 1 to the accompanying Figure 2In a preferred embodiment, the top end of the column 5 is provided with a lifting hole 52 to facilitate hoisting of the column 5. The column 5 is a hollow structure, so that the overall mass of the column 5 is relatively light, facilitating transportation of the column 5.

[0028] Please refer to the accompanying drawings Figure 1 to the accompanying drawings Figure 2 In a preferred embodiment, the upper end of the column 5 is transversely provided with a limiting piece 6 fixedly inserted into the column 5. The limiting piece 6 is located above the upper surface of the through hole 41, and the transverse length of the limiting piece 6 is greater than the diameter of the through hole 41, so as to prevent the column 5 from being completely pulled out of the through hole 41. Meanwhile, when the column 5 is pulled out, the connecting piece 8 connected to the lifting mechanism 3 is wound around the side wall of the column 5 and located below the limiting piece 6. At this time, the limiting piece 6 facilitates pulling out of the column 5 and prevents the connecting piece 8 from falling off the column 5.

[0029] Please refer to the accompanying drawings Figure 1 to the accompanying drawings Figure 2 In a preferred embodiment, the lifting mechanism 3 is preferably a hydraulic telescopic cylinder. One end of the connecting piece 8 is fixedly connected to the support 2 to serve as a stabilizer, the other end is wound around the side wall of the column 5 to be connected to the column 5, and the intermediate part is connected to the end of the telescopic rod of the hydraulic telescopic cylinder, so that the telescopic rod can drive the column 5 to move upward when the telescopic rod is extended. However, it should be understood by those skilled in the art that in other embodiments, the lifting mechanism 3 can also be other driving mechanisms, which can have the same effect as the present embodiment.

[0030] Please refer to the accompanying drawings Figure 1 to the accompanying drawings Figure 2 In a preferred embodiment, the side wall of the column 5 is vertically and equidistantly provided with a plurality of groups of through insertion holes 53. The through insertion holes 53 are located below the limiting piece 6 and are used for insertion of the bolt 7. The transverse length of the bolt 7 is greater than the diameter of the through hole 41, so as to facilitate subsequent complete pulling out of the column 5 from the seabed. The distance between the limiting piece 6 and the uppermost through insertion hole 53 and the distance between adjacent two through insertion holes 53 are both less than the lifting stroke of the lifting mechanism 3 (i.e. the extension stroke of the telescopic rod of the hydraulic telescopic cylinder). It can be understood that in the present embodiment, when the column 5 is pulled out and the telescopic rod is fully extended each time, the through insertion holes 53 will be sequentially located above the upper surface of the through hole 41 from top to bottom, so as to facilitate insertion of the bolt 7 into the corresponding through insertion hole 53 and prevent the column 5 from falling.

[0031] The following is the use method of the ship fixing device of the present application:

[0032] The initial state of the column 5 is that the through insertion hole 53 at the lowermost of the column 5 is above the upper surface of the through hole 41, at this time, the plug 7 is inserted in the through insertion hole 53;

[0033] When the column 5 needs to be inserted, only the plug 7 is pulled out, and the column 5 is inserted under its own gravity;

[0034] When the column 5 needs to be pulled out, the connecting piece 8 should be tightly wound on the side wall of the column 5 and below the limiting piece 6, at this time, the hydraulic telescopic cylinder is started, the telescopic rod of the hydraulic telescopic cylinder is extended upward and drives the column 5 to move upward through the connecting piece 8; since the spacing between the limiting piece 6 and the uppermost through insertion hole 53 and the adjacent two through insertion holes 53 is less than the extension stroke of the telescopic rod, when the telescopic rod is extended to the full stroke, at this time, the uppermost through insertion hole 53 is above the upper surface of the through hole 41 of the support table 4, at this time, the plug 7 needs to be inserted into the through insertion hole 53; the telescopic rod is retracted, and the connecting piece 8 is wound again on the lower side wall of the column 5, the hydraulic telescopic cylinder is started again, the telescopic rod of the hydraulic telescopic cylinder is extended upward to continue to drive the column 5 to move upward, the plug 7 can be pulled out at any time between the process of winding the connecting piece 8 on the side wall of the column 5 and the telescopic rod extending upward, so that the plug 7 can be pulled out without affecting the next insertion of the column 5 into the seabed; the cycle is repeated until the column 5 is completely pulled out from the seabed, and finally the plug 7 is inserted into the through insertion hole 53 at the lowermost of the column 5, so as to return to the initial state of the column 5. When the column 5 is inserted into the seabed, the through insertion hole 53 can also allow seawater to enter the inside of the column 5, so that the column 5 is more firmly inserted into the seabed.

[0035] The above-described embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, therefore, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
