Description

Technical Field

[0001] The present invention relates to the technical field of marine anchoring technology, and more particularly to a shared torpedo anchor and an installation method thereof. Background Art

[0002] In related technologies, a torpedo anchor is a foundation for mooring deep-sea facilities. It is shaped like a torpedo and has an outer surface of a conical cylindrical steel pipe. During installation, the torpedo anchor is released at a certain water depth, and it relies on the kinetic energy obtained by falling under its own gravity to uplift the seabed.

[0003] After the torpedo anchor penetrates into the seabed, the anchor chain of the torpedo anchor can be connected to an offshore structure on the sea surface, thereby playing a role in stabilizing the offshore structure. Among them, the existing anchor chain of the torpedo anchor is usually connected to one offshore structure to anchor the offshore structure. Further, when there are multiple offshore structures, each offshore structure requires a torpedo anchor for anchoring. Therefore, multiple torpedo anchors need to be put into the seabed. However, putting multiple torpedo anchors into the ocean requires a lot of time and effort, resulting in a long time consumption and high cost. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a shared torpedo anchor that can anchor multiple offshore structures simultaneously, thereby saving time and cost.

[0005] The present invention also provides an installation method for the shared torpedo anchor.

[0006] The shared torpedo anchor according to the first aspect embodiment of the present invention includes:

[0007] An anchor body;

[0008] Wing plates, connected to the outer peripheral surface of the anchor body, and the normal direction of the wing plates is perpendicular to the axial direction of the anchor body;

[0009] Plate anchors, rotatably connected to the wing plates;

[0010] A first anchor chain, connected to the anchor body, and the first anchor chain is used to connect to one offshore structure;

[0011] A second anchor chain, connected to the plate anchor, and the second anchor chain is used to connect to another offshore structure;

[0012] Wherein, the second anchor chain can be driven to move and drive the plate anchor to move, so that the plate anchor switches from a closed state to an open state. When the plate anchor is in the closed state, the surface of the plate anchor fits with the surface of the wing plate; when the plate anchor is in the open state, an opening is formed between the surface of the plate anchor and the surface of the wing plate, and the opening faces the bottom of the anchor body.

[0013] The shared torpedo anchor according to an embodiment of the present invention has at least the following beneficial effects: After the plate anchor is rotatably connected to the wing plate, the plate anchor is connected to the second anchor chain. When the surface of the plate anchor fits the surface of the wing plate, the plate anchor is in a closed state. At this time, the shared torpedo anchor can be released to the seabed. Then, by connecting the second anchor chain to the marine structure, the second anchor chain is pulled, so that the second anchor chain drives the plate anchor to move, thereby switching the plate anchor from the closed state to the open state. When the plate anchor is in the open state, both the plate anchor and the wing plate of the shared torpedo anchor are in contact with the seabed, having a large contact area, so that the shared torpedo anchor has better anti-pulling performance. Further, by connecting the first anchor chain to one marine structure and the second anchor chain to another marine structure, two marine structures share one shared torpedo anchor. In this way, compared with the need to put multiple torpedo anchors into the seabed in the prior art, one shared torpedo anchor of the present application can anchor multiple marine structures at the same time, thus saving time and cost.

[0014] For the shared torpedo anchor according to some embodiments of the present invention, there are a plurality of the wing plates, and the plurality of wing plates are arranged around the circumference of the anchor body.

[0015] For the shared torpedo anchor according to some embodiments of the present invention, there are two of the plate anchors and two of the second anchor chains. Two of the plate anchors are respectively arranged on both sides of the wing plate, and each plate anchor is connected to one second anchor chain.

[0016] For the shared torpedo anchor according to some embodiments of the present invention, the plate anchor includes a main board, a first side board and a second side board. The main board is rotatably connected to the wing plate. One end of the first side board is connected to the main board, and the other end is connected to the second side board; one end of the second side board is connected to the main board, and the other end is connected to the first side board; wherein, the second anchor chain is connected to the same end of the first side board and the second side board that are both far away from the main board.

[0017] For the shared torpedo anchor according to some embodiments of the present invention, the first side board, the second side board and the main board together form a triangular structure, and the triangular structure has a through hole axially penetrating along the anchor body.

[0018] For the shared torpedo anchor according to some embodiments of the present invention, the plate anchor is pin-connected to the wing plate.

[0019] For the shared torpedo anchor according to some embodiments of the present invention, the wing plate has magnetism, the material of the plate anchor is a metal material, and the magnetism of the wing plate can make the plate anchor fit on the surface of the wing plate.

[0020] According to some embodiments of the present invention, for the shared torpedo anchor, the plate anchor has magnetism, the wing plate is made of a metal material, and the magnetism of the plate anchor can make the plate anchor adhere to the surface of the wing plate.

[0021] According to some embodiments of the present invention, for the shared torpedo anchor, both the plate anchor and the wing plate have magnetism, and the magnetism of the plate anchor is opposite to that of the wing plate. The magnetism of the plate anchor and the wing plate can make the plate anchor adhere to the surface of the wing plate.

[0022] According to an embodiment of the second aspect of the present invention, a method for installing a shared torpedo anchor is used to install a shared torpedo anchor. The shared torpedo anchor includes:

[0023] An anchor body;

[0024] A wing plate, connected to the outer peripheral surface of the anchor body, and the normal direction of the wing plate is perpendicular to the axial direction of the anchor body;

[0025] A plate anchor, rotatably connected to the wing plate;

[0026] A first anchor chain, connected to the anchor body, and the first anchor chain is used to connect to an ocean structure;

[0027] A second anchor chain, connected to the plate anchor, and the second anchor chain is used to connect to another ocean structure;

[0028] Wherein, the second anchor chain can be driven to move and drive the plate anchor to move, so that the plate anchor switches from a closed state to an open state. When the plate anchor is in the closed state, the surface of the plate anchor fits with the surface of the wing plate; when the plate anchor is in the open state, an opening is formed between the surface of the plate anchor and the surface of the wing plate, and the opening faces the bottom of the anchor body;

[0029] Steps of the method for installing the shared torpedo anchor:

[0030] Make the plate anchor in the closed state;

[0031] Release the shared torpedo anchor into the ocean;

[0032] Pull the second anchor chain to make the plate anchor in the open state.

[0033] The installation method of the shared torpedo anchor according to the embodiments of the present invention has at least the following beneficial effects: After the plate anchor is rotatably connected to the wing plate, the plate anchor is connected to the second anchor chain. When the surface of the plate anchor fits the surface of the wing plate, the plate anchor is in a closed state. At this time, the shared torpedo anchor is released to the seabed. After that, the second anchor chain is connected to the marine structure, and then the second anchor chain is pulled to drive the plate anchor to move, so that the plate anchor switches from the closed state to the open state. When the plate anchor is in the open state, both the plate anchor and the wing plate of the shared torpedo anchor are in contact with the seabed, having a large contact area, so that the shared torpedo anchor has better anti-pulling performance. Further, the first anchor chain is connected to one marine structure, and the second anchor chain is connected to another marine structure, so that two marine structures share a shared torpedo anchor. In this way, after the shared torpedo anchor of the present application is installed on the seabed, the shared torpedo anchor can anchor multiple marine structures at the same time, thus saving time and cost.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0052] Please refer to Figure 1 、 Figure 2 and Figure 3 , in some embodiments, the shared torpedo anchor 10 includes: an anchor body 100, wing plates 200, a plate anchor 300, a first anchor chain 500, and a second anchor chain 600. Among them, the anchor body 100 is cylindrical, and its head is semi-circular or conical, so as to facilitate penetration into the seabed. The interior of the anchor body 100 can be a hollow structure and can be filled with high-density materials such as concrete, scrap metal, etc., so as to increase the weight of the anchor body 100 itself and increase the energy for penetrating into the seabed without relying on other devices. The wing plates 200 are connected to the outer peripheral surface of the anchor body 100. For example, the wing plates 200 are welded to the outer peripheral surface of the anchor body 100, and the normal direction of the wing plates 200 is perpendicular to the axial direction of the anchor body 100. Thus, when the anchor body 100 penetrates into the seabed, the wing plates 200 will not obstruct or offset the penetration energy of the anchor body 100. The plate anchor 300 is rotatably connected to the wing plates 200, so that it can rotate relative to the wing plates 200. The first anchor chain 500 is connected to the top of the anchor body 100, and an installation hole is provided at the top of the anchor body 100 to facilitate the connection between the first anchor chain 500 and the anchor body 100. The second anchor chain 600 is connected to the plate anchor 300. Among them, the second anchor chain 600 can be driven to move and drive the plate anchor 300 to move, so that the plate anchor 300 is switched from the closed state to the open state. When the plate anchor 300 is in the closed state, the surface of the plate anchor 300 fits with the surface of the wing plates 200; when the plate anchor 300 is in the open state, an opening 400 is formed between the surface of the plate anchor 300 and the surface of the wing plates 200, and the opening 400 faces the bottom of the anchor body 100. Among them, Figure 1 shows the closed state of the plate anchor 300 in the shared torpedo anchor 10, Figure 3The open state of the plate anchor 300 in the shared torpedo anchor 10 is shown. Specifically, after the plate anchor 300 is rotatably connected to the wing plate 200, the plate anchor 300 is connected to the second anchor chain 600. When the surface of the plate anchor 300 is in contact with the surface of the wing plate 200, the plate anchor 300 is in a closed state. At this time, the shared torpedo anchor 10 can be released to the seabed. After that, the second anchor chain 600 is connected to the marine structure, and then the second anchor chain 600 is pulled, so that the second anchor chain 600 drives the plate anchor 300 to move, and thus the plate anchor 300 is switched from the closed state to the open state. When the plate anchor 300 is in the open state, both the plate anchor 300 and the wing plate 200 of the shared torpedo anchor 10 are in contact with the seabed, having a large contact area, so that the shared torpedo anchor 10 has good anti-pulling performance and good integrity. Further, the first anchor chain 500 is connected to one marine structure, and the second anchor chain 600 is connected to another marine structure, so that two marine structures share one shared torpedo anchor 10. When there are multiple second anchor chains 600, the shared torpedo anchor 10 can be connected to multiple marine structures. In this way, compared with the need to put multiple torpedo anchors into the seabed in the prior art, one shared torpedo anchor 10 of the present application can anchor multiple marine structures at the same time, thus saving time and cost.

[0053] Further, please refer to Figure 4 , the opening 400 formed by the surface of the plate anchor 300 and the surface of the wing plate 200 will be explained below. Among them, the wing plate 200 can be rectangular in shape, and the long side of the wing plate 200 is connected to the anchor body 100 and extends along the axial direction of the anchor body 100. The plate anchor 300 can also be rectangular in shape, and the ratio of its long side to the short side can be 3:2. Among them, the long side of the plate anchor 300 is connected to the wing plate 200, so that the surface of the plate anchor 300 and the surface of the wing plate 200 form an opening 400. It should be noted that the opening 400 can only be formed when the plate anchor 300 is in the open state. When the plate anchor 300 is in the closed state, the surface of the plate anchor 300 is in contact with the surface of the wing plate 200, and there is no opening 400. It can be imagined that the plate anchor 300 will exert a resistance on the anchor body 100 in the axial direction of the anchor body 100, so that when the shared torpedo anchor 10 anchors more marine structures, the anti-pulling ability of the shared torpedo anchor 10 is better.

[0054] Furthermore, the shared torpedo anchor 10 of the present application can not only anchor multiple marine structures simultaneously, but also provide multi-directional uplift resistance. After the shared torpedo anchor 10 penetrates into the seabed, multiple plate anchors 300 at the same depth position are in an open state (at this time, the plate anchors 300 can be perpendicular to the second anchor chain 600). After the multiple plate anchors 300 are subjected to the tension of the second anchor chain 600, the horizontal component forces transmitted by the multiple second anchor chains 600 to the plate anchors 300 can be basically offset from each other. Therefore, the horizontal and vertical bearing capacities of the shared torpedo anchor 10 of the present application are multiple times that of the torpedo anchor in the prior art. In addition, due to the complex and variable marine environmental loads, the loads received by each structure may be different. Therefore, when a large load is applied to one plate anchor 300 of the shared torpedo anchor 10 of the present application, this plate anchor 300 will contact the seabed, and at the same time, other plate anchors 300 will also contact the seabed. In other words, the multiple plate anchors 300 increase the contact area between the shared torpedo anchor 10 and the seabed, thereby increasing the uplift resistance. In addition, because the shared torpedo anchor 10 of the present application has a relatively large contact area with the seabed, it has good uplift resistance. Therefore, after the shared torpedo anchor 10 penetrates into the seabed, its displacement deformation is small and its integrity is strong.

[0055] Further, please refer to Figure 5 , in some embodiments, there are multiple wing plates 200, and the multiple wing plates 200 are arranged circumferentially around the anchor body 100. Specifically, there can be four wing plates 200, and among them, the four wing plates 200 are circumferentially arranged around the anchor body 100. The included angle between two adjacent wing plates 200 can be 90 degrees. After the shared torpedo anchor 10 penetrates into the seabed, the wing plates 200 can increase the contact area between the shared torpedo anchor 10 and the seabed, so that the shared torpedo anchor 10 has good uplift resistance.

[0056] In some embodiments, one end of the wing plate 200 close to the bottom of the anchor body 100 is provided with an inclined surface, and along the direction from the bottom of the anchor body 100 to the top of the anchor body 100, the height of the inclined surface gradually increases. In this way, the design of the inclined surface can reduce the resistance of the shared torpedo anchor 10 when penetrating into the seabed.

[0057] In some embodiments, the included angle between the side end of the wing plate 200 far from the anchor body 100 (the side end where the wing plate 200 is connected to the anchor body 100 is: the side end of the wing plate 200 close to the anchor body 100) and the bottom end of the wing plate 200 is an obtuse angle. The obtuse angle can facilitate the wing plate 200 to cut the soil body, thereby reducing the resistance of the shared torpedo anchor 10 when penetrating into the seabed.

[0058] Further, please refer to Figure 6 , in some embodiments, there are two plate anchors 300 and two second anchor chains 600. Two of the plate anchors 300 are respectively arranged on both sides of the wing plate 200, and each plate anchor 300 is connected to one second anchor chain 600. Specifically, please refer toFigure 6 , a shared torpedo anchor 10 is shown in the figure. Among them, the shared torpedo anchor 10 has four wing plates 200. On both sides of one wing plate 200, there are two plate anchors 300, and each plate anchor 300 is connected to a second anchor chain 600. Among them, in Figure 6 , the shared torpedo anchor 10 can anchor nine marine structures. Specifically, the first anchor chain 500 connected to the anchor body 100 can be connected to one marine structure, and eight marine structures can be connected to the eight second anchor chains 600 connected to the eight plate anchors 300. In this way, the shared torpedo anchor 10 can anchor multiple marine structures at the same time, saving the time and cost of putting multiple torpedo anchors into the seabed. In addition, since there can be multiple plate anchors 300, in order to avoid interference between multiple plate anchors 300 when they are in the open state respectively. The plate anchors 300 on adjacent two wing plates 200 can be staggeredly arranged. The staggered arrangement can specifically be that two plate anchors 300 are connected to the top of one wing plate 200, and the other two plate anchors 300 are connected to the middle position of another wing plate 200. In this way, when each plate anchor 300 is in the open state, they do not interfere with each other.

[0059] The specific structure of the plate anchor 300 will be introduced below. Please refer to Figure 7 , in some embodiments, the plate anchor 300 includes a main board 310, a first side board 320 and a second side board 330. The main board 310 is rotatably connected to the wing plate 200. One end of the first side board 320 is connected to the main board 310, and the other end is connected to the second side board 330. One end of the second side board 330 is connected to the main board 310, and the other end is connected to the first side board 320. Among them, the second anchor chain 600 is connected to the same end of the first side board 320 and the second side board 330 that are both far away from the main board 310. Specifically, the specific way that the second anchor chain 600 is connected to the same end of the first side board 320 and the second side board 330 that are both far away from the main board 310 can be that collar rings are arranged on the same end of the first side board 320 and the second side board 330 that are both far away from the main board 310, and the collar rings are connected to the second anchor chain 600. The main board 310, the first side board 320 and the second side board 330 together form a triangular structure. The way that the first side board 320 and the second side board 330 are connected to the main board 310, compared with the way that the second anchor chain 600 is directly connected to the main board 310, when the first side board 320 and the second side board 330 are connected to the main board 310, they can share the pulling force exerted by the second anchor chain 600, thus avoiding damage to the main board 310. Among them, the triangular structure has good stability. Thus, after one end of the second anchor chain 600 is connected to the plate anchor 300 and the other end is connected to the marine structure, the safety of the marine structure can be better.

[0060] Please refer to Figure 7, in some embodiments, when the plate anchor 300 is in the closed state, the first side plate 320, the second side plate 330 and the main plate 310 together form a triangular structure, and the triangular structure has a through hole 340 axially penetrating along the anchor body 100. Among them, the first side plate 320 is welded to the main plate 310, and the weld between the two is parallel to the axis of the anchor body 100. The second side plate 330 is welded to the main plate 310, and the weld between the two is parallel to the axis of the anchor body 100. After the through hole 340 axially penetrates along the anchor body 100, in this way, when the shared torpedo anchor 10 penetrates into the seabed, the resistance can be reduced, so that the shared torpedo anchor 10 can penetrate into the seabed to a greater depth.

[0061] Furthermore, in some embodiments, the plate anchor 300 is pin-connected to the wing plate 200. Specifically, after the plate anchor 300 is pin-connected to the wing plate 200, the plate anchor 300 can rotate relative to the wing plate 200. Among them, the pin-connection method has a simple process and is convenient for processing, which can improve the work efficiency of the staff.

[0062] Since when the shared torpedo anchor 10 penetrates into the seabed, it is necessary to keep the plate anchor 300 attached to the surface of the wing plate 200, so as to reduce the resistance of the shared torpedo anchor 10 penetrating into the seabed and make the penetration depth of the shared torpedo anchor 10 larger. Therefore, when the plate anchor 300 is in the closed state, the shared torpedo anchor 10 can be penetrated into the seabed. Specifically, there are the following ways to make the plate anchor 300 in the closed state. Way 1, in some embodiments, the wing plate 200 has magnetism, the material of the plate anchor 300 is a metal material, and the magnetism of the wing plate 200 can make the plate anchor 300 attached to the surface of the wing plate 200. Specifically, before the shared torpedo anchor 10 penetrates into the seabed, the plate anchor 300 is attached to the wing plate 200 under the action of magnetism, so that the resistance of the shared torpedo anchor 10 penetrating into the seabed can be reduced. After that, to make the plate anchor 300 in the open state, just pull the second anchor chain 600. The force for pulling the second anchor chain 600 is greater than the magnetic attraction force.

[0063] Way 2, in some embodiments, the plate anchor 300 has magnetism, the material of the wing plate 200 is a metal material, and the magnetism of the plate anchor 300 can make the plate anchor 300 attached to the surface of the wing plate 200. Specifically, before the shared torpedo anchor 10 penetrates into the seabed, the plate anchor 300 is attached to the wing plate 200 under the action of magnetism, so that the resistance of the shared torpedo anchor 10 penetrating into the seabed can be reduced. After that, to make the plate anchor 300 in the open state, just pull the second anchor chain 600. The force for pulling the second anchor chain 600 is greater than the magnetic attraction force.

[0064] In Method 3, in some embodiments, both the plate anchor 300 and the wing plate 200 have magnetism, and the magnetism of the plate anchor 300 is opposite to that of the wing plate 200. The magnetism of the plate anchor 300 and the wing plate 200 can make the plate anchor 300 fit on the surface of the wing plate 200. Specifically, before the shared torpedo anchor 10 penetrates into the seabed, the plate anchor 300 fits together with the wing plate 200 under the action of magnetism, thereby reducing the resistance of the shared torpedo anchor 10 when penetrating into the seabed. After that, to make the plate anchor 300 in the open state, just pull the second anchor chain 600. The force for pulling the second anchor chain 600 is greater than the magnetic attraction force.

[0065] The present application also proposes an installation method for the shared torpedo anchor 10. In some embodiments, the installation method for the shared torpedo anchor 10 is used to install the shared torpedo anchor 10. First, the specific structure of the shared torpedo anchor 10 is introduced. The shared torpedo anchor 10 includes: an anchor body 100, a wing plate 200, a plate anchor 300, a first anchor chain 500, and a second anchor chain 600. Among them, the anchor body 100 is cylindrical, and its head is semi-circular or conical, so as to facilitate penetration into the seabed. The inside of the anchor body 100 can be a hollow structure and can be filled with high-density materials, such as concrete, scrap metal, etc., so as to increase the weight of the anchor body 100 itself and increase the energy for penetrating into the seabed without relying on other equipment. The wing plate 200 is connected to the outer peripheral surface of the anchor body 100. For example, the wing plate 200 is welded to the outer peripheral surface of the anchor body 100, and the normal direction of the wing plate 200 is perpendicular to the axial direction of the anchor body 100. Thus, when the anchor body 100 penetrates into the seabed, the wing plate 200 will not hinder or offset the penetration energy of the anchor body 100. The plate anchor 300 is rotatably connected to the wing plate 200, so that it can rotate relative to the wing plate 200. The first anchor chain 500 is connected to the top of the anchor body 100, and an installation hole is provided at the top of the anchor body 100, which is convenient for connecting the first anchor chain 500 and the anchor body 100. The second anchor chain 600 is connected to the plate anchor 300. Among them, the second anchor chain 600 can be driven to move and drive the plate anchor 300 to move, so that the plate anchor 300 is switched from the closed state to the open state. When the plate anchor 300 is in the closed state, the surface of the plate anchor 300 fits with the surface of the wing plate 200; when the plate anchor 300 is in the open state, an opening 400 is formed between the surface of the plate anchor 300 and the surface of the wing plate 200, and the opening 400 faces the bottom of the anchor body 100.

[0066] Further, please refer to Figure 8 and Figure 9 , the steps of the installation method for the shared torpedo anchor 10 are as follows:

[0067] S100. Make the plate anchor 300 in the closed state;

[0068] S200. Release the shared torpedo anchor 10 into the ocean;

[0069] S300. Pull the second anchor chain 600 to place the plate anchor 300 in the open state.

[0070] Specifically, after the plate anchor 300 is rotatably connected to the wing plate 200, the plate anchor 300 is connected to the second anchor chain 600. When the surface of the plate anchor 300 is in contact with the surface of the wing plate 200, the plate anchor 300 is in the closed state. At this time, the shared torpedo anchor 10 is released to the seabed. After that, the second anchor chain 600 is connected to the marine structure, so as to pull the second anchor chain 600, drive the plate anchor 300 to move by the second anchor chain 600, and thus switch the plate anchor 300 from the closed state to the open state. When the plate anchor 300 is in the open state, both the plate anchor 300 and the wing plate 200 of the shared torpedo anchor 10 are in contact with the seabed, having a large contact area, so that the shared torpedo anchor 10 has better anti-pulling performance. Further, the first anchor chain 500 is connected to one marine structure, and the second anchor chain 600 is connected to another marine structure, so that two marine structures share a shared torpedo anchor 10. When there are multiple second anchor chains 600, the shared torpedo anchor 10 can be connected to multiple marine structures. In this way, after the installation method of the shared torpedo anchor 10 of the present application installs the shared torpedo anchor 10 on the seabed, the shared torpedo anchor 10 can anchor multiple marine structures at the same time, thus saving time and cost.

[0071] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
