Description

Technical Field

[0001] The present application relates to the technical field of ship anchoring, and in particular to an anchoring system and a ship. Background Art

[0002] In the related art, in order to limit the gross tonnage and light ship weight of small ships, under the premise of meeting the specifications, steel wire rope (anchor cable) can be used to replace the anchor chain, and the navigation anchor cable can be stored in the drum of the anchor machine or winch on the deck, thereby saving the anchor chain compartment space. For anchor boats or tugboats with a push function, in order to prevent the anchor and anchor frame from scratching the push object, the navigation anchor must be stored in the fender of the bow. The traditional storage method is to design an anchor chain barrel plus an anchor hole or an anchor chain barrel plus an anchor platform. However, the anchor chain barrel will occupy the hull space below the deck, and the manufacturing and processing of the anchor hole and the anchor platform are relatively complicated and difficult. In addition, the center of gravity of the unbalanced anchor is on the anchor claw. If the storage angle (the angle between the center line of the anchor handle and the horizontal line) is too large, the anchor claw cannot fall down automatically, and the anchor claw will randomly appear when the anchor is collected, and the anchor claw will face up and the anchor claw will face down. However, the traditional anchor hole, anchor platform or anchor frame is generally only applicable to a certain anchor claw direction when collecting anchors: either only applicable to the situation where the anchor claw faces up, or only applicable to the situation where the anchor claw faces down. Summary of the invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes an anchoring system for a ship with a push function, which does not occupy the hull space below the deck and is applicable not only to the case where the anchor claw is facing upward, but also to the case where the anchor claw is facing downward when the anchor is collected.

[0004] The application also proposes a ship having the above-mentioned mooring system.

[0029] Reference Figures 1 to 4 According to an embodiment of the present application, the mooring system is used for a ship with a pushing function, and includes a fender seat 100, an anchor assembly, a fairlead 300 and an anchor frame 400.

[0030] Specifically, the fender seat 100 is connected to the bow and / or the side and is used to install the fender a. The anchor assembly includes an anchor chain 210, an unbalanced anchor 220 and an anchor cable 230. One end of the anchor chain 210 is connected to the unbalanced anchor 220, and the other end of the anchor chain 210 is connected to one end of the anchor cable 230. The other end of the anchor cable 230 is used to be fixed to the drum of the anchor machine or winch on the deck b. The fairlead 300 is a cylindrical structure with two ends opened. The chock 300 is provided on the fender seat 100. One end surface of the chock 300 is flush with the top surface of the fender seat 100, and the other end surface of the chock 300 is flush with the bottom surface of the fender seat 100. The chock 300 is used to pass the anchor chain 210 and the anchor cable 230. The anchor frame 400 is annular and is used to clamp the unbalanced anchor 220. A connecting piece 500 is provided between the top of the anchor frame 400 and the bottom of the fender seat 100. The anchor frame 400 and the chock 300 are connected to each other. The end opening (the end opening located on the bottom surface of the fender seat 100) is arranged in a symmetrical manner, and a gap is provided between the top of the anchor frame 400 and the bottom of the fender seat 100 for avoiding the unbalanced anchor 220, so that the unbalanced anchor 220 will not collide with the bottom of the fender seat 100 when it is caught on the anchor frame 400, and the anchor frame 400 is located within the coverage range of the fender seat 100 and can make the unbalanced anchor 220 when caught on the anchor frame 400 be located within the coverage range of the fender seat 100 , that is, the orthographic projection of the anchor frame 400 along the vertical direction completely falls within the orthographic projection of the fender seat 100 along the vertical direction, wherein, when the unbalanced anchor 220 is engaged with the anchor frame 400, the orthographic projection of the unbalanced anchor 220 along the vertical direction completely falls within the orthographic projection of the fender seat 100 along the vertical direction, and there is a gap between the side of the anchor frame 400 close to the hull and the bottom plate c for avoiding the unbalanced anchor 220, so that the unbalanced anchor 220 will not collide with the bottom plate c when engaged with the anchor frame 400.

[0031] When in use, since the anchor frame 400 is annular, when the unbalanced anchor 220 is stored, no matter whether the anchor claw of the unbalanced anchor 220 is facing upward or downward, the angle formed by the anchor claw of the unbalanced anchor 220 and the anchor handle can be locked on the anchor frame 400, so that the mooring system of the embodiment of the present application is not only applicable to the situation where the anchor claw is facing upward, but also applicable to the situation where the anchor claw is facing downward when the anchor is collected. Therefore, when collecting the anchor, the anchor will not be repeatedly collected and released due to the wrong direction of the anchor claw of the unbalanced anchor 220, which is conducive to reducing the difficulty of operation and shortening the operation time. Among them, the anchor frame 400 is located within the coverage range of the fender seat 100 and can make the unbalanced anchor 220 when it is locked on the anchor frame 400 located within the coverage range of the fender seat 100, so as to facilitate the ship's pushing operation. In addition, the relevant structure of the mooring system of the embodiment of the present application will not occupy the hull space below the deck b, that is, it will not damage the integrity of the ship's cabin, which is conducive to reducing the difficulty of implementation.

[0032] It should be noted that, in some of the embodiments, the center line of the anchor frame 400 is parallel to the center line of the fairlead 300, so as to facilitate the insertion of the anchor chain 210 and the anchor cable 230, and at the same time reduce the bending of the anchor chain 210 and the anchor cable 230 during the process of retracting and releasing the anchor, thereby helping to reduce the contact between the anchor chain 210 and the anchor cable 230 and other components, and further helping to reduce the wear of the anchor chain 210 and the anchor cable 230.

[0033] It should be noted that, in some of the embodiments, the fender seat 100 is a steel structure, which is beneficial to ensure the structural strength of the fender seat 100, so that the fender seat 100 has higher stability and reliability.

[0034] It should be noted that, in some of the embodiments, the fender a installed on the fender seat 100 may be a rubber structure or a wooden structure, which is not limited herein.

[0035] It should be noted that, in some of the embodiments, the fender seat 100 is welded to the bow and the side. Of course, the fender seat 100 may also be welded only to the bow or only to the side, which is not limited here.

[0036] Reference Figures 1 to 3 In some embodiments, the cross-section of the anchor frame 400 is circular, that is, there is no sharp structure on the surface of the anchor frame 400 to scratch and wear the anchor chain 210 and the anchor cable 230, which is conducive to reducing the wear of the anchor frame 400 on the anchor chain 210 and the anchor cable 230. Specifically, the anchor frame 400 is welded by seamless steel pipes and elbows, wherein the seamless steel pipes and elbows are standard parts, with low procurement costs and short procurement cycles.

[0037] It should be noted that, in some embodiments, the connector 500 is made of a seamless steel tube with a circular outer profile in cross section, so that there is no sharp structure on the surface of the connector 500 to scratch and wear the anchor chain 210 and the anchor cable 230, which is conducive to reducing the wear of the connector 500 on the anchor chain 210 and the anchor cable 230. Specifically, one end is welded to the top of the anchor frame 400, and the other end is welded to the bottom of the fender seat 100.

[0038] Reference Figures 1 to 4 In some embodiments, a plurality of spaced connectors 500 are provided between the top of the anchor frame 400 and the bottom of the fender seat 100, and all the connectors 500 enclose a bypass channel for passing the anchor chain 210 and the anchor cable 230, and the inner diameter of the bypass channel increases from the top of the anchor frame 400 to the bottom of the fender seat 100. In the process of retracting and releasing the anchor, it is helpful to reduce the contact between the anchor chain 210 and the anchor cable 230 and the connector 500, thereby helping to reduce the wear of the anchor chain 210 and the anchor cable 230.

[0039] Reference Figures 1 to 3 In some of the embodiments, a raised first transition portion 600 is provided at the top of the fender seat 100 corresponding to the corresponding end surface of the fairlead 300. The first transition portion 600 is in a long strip shape and is provided along the outer edge of the corresponding end surface of the fairlead 300. The upper portion of the first transition portion 600 has an outwardly convex arc-shaped transition surface, which is beneficial to prevent the opening at the corresponding end of the fairlead 300 from scratching and wearing the anchor chain 210 and the anchor cable 230 due to being too sharp, thereby helping to reduce the wear of the anchor chain 210 and the anchor cable 230.

[0040] Specifically, the first transition part 600 is a steel structure. The outer contour of the cross section of the first transition part 600 is semicircular. Of course, the outer contour of the cross section of the first transition part 600 can also be circular or other shapes (such as a shape formed by splicing a semicircle and a rectangle). In addition, a smooth transition process can also be performed at the junction between the top of the fender seat 100 and the corresponding end of the fairlead 300 and the opening of the corresponding end of the fairlead 300, which is not limited here.

[0041] Reference Figures 1 to 3 In some of the embodiments, a raised second transition portion 700 is provided at the bottom of the fender seat 100 corresponding to the corresponding end surface of the fairlead 300. The second transition portion 700 is in a long strip shape and is provided along the outer edge of the corresponding end surface of the fairlead 300. The lower part of the second transition portion 700 has an outwardly convex arc-shaped transition surface, which is beneficial to prevent the opening at the corresponding end of the fairlead 300 from scratching and wearing the anchor chain 210 and the anchor cable 230 due to being too sharp, thereby helping to reduce the wear of the anchor chain 210 and the anchor cable 230.

[0042] Specifically, the second transition portion 700 is a steel structure. The outer contour of the cross section of the second transition portion 700 is semicircular. Of course, the outer contour of the cross section of the second transition portion 700 can also be circular or other shapes (such as a shape formed by splicing a semicircle and a rectangle). In addition, a smooth transition process can also be performed at the joint between the bottom of the fender seat 100 and the corresponding end of the fairlead 300 and the opening of the corresponding end of the fairlead 300, which is not limited here.

[0043] Reference Figures 1 to 3 In some of the embodiments, the fender seat 100 is an internal hollow structure, and a reinforcing rib 800 is provided between the outer wall of the fairlead 300 and the inner wall of the fender seat 100, which is beneficial to enhance the stability and reliability of the fairlead 300 during operation.

[0044] Reference Figures 1 to 3In some embodiments, the fairlead 300 is tilted so that the distance between the end of the fairlead 300 located at the top of the fender seat 100 and the hull is smaller than the distance between the end of the fairlead 300 located at the bottom of the fender seat 100 and the hull. During the process of retracting and releasing the anchor, the bending degree of the anchor chain 210 and the anchor cable 230 at the end opening of the fairlead 300 is reduced, thereby reducing the wear of the anchor chain 210 and the anchor cable 230.

[0045] Reference Figures 1 to 3 In some embodiments, the mooring system further includes a fairlead 900 for guiding the anchor chain 210 and the anchor cable 230, which can guide the retraction and deployment of the anchor chain 210 and the anchor cable 230. Specifically, the fairlead 900 is arranged on the deck b, and can be a roller fairlead, a roller fairlead, a fairlead clamp or other fairlead structures, which are not limited here.
