Description

Technical Field

[0001] The present invention relates to the field of ships and marine engineering, and in particular to a multi-purpose floating body mooring device and an implementation method thereof. Background Art

[0002] Offshore floating bodies often float on the water for a period of time due to the needs of operating platforms or temporary anchoring. In order to prevent the floating body from drifting away, anchor bodies and anchor chains are generally used to provide anchor grip to anchor the floating body in the target sea area, or moor it to a fixed dock by a cable.

[0003] In deep water areas, the catenary section of the anchor chain is longer, and the mooring system can provide sufficient mooring force; in shallow water areas, the catenary section is shorter, the force provided by the catenary is smaller, and the floating body will produce a larger displacement due to wind flow load when anchored.

[0004] However, in deep water areas, due to the influence of sea waves, and as we all know, the shaking amplitude is greater when anchored than when sailing, it is easier for the floating body (or ship) to shake.

[0005] Therefore, a multi-purpose mooring device is needed to enable the floating body to adapt to both deep water areas and shallow water areas.

[0006] The above problems are worth solving. Summary of the invention

[0007] In order to overcome the deficiencies of the prior art, the present invention provides a multi-purpose floating anchoring device and an implementation method thereof.

[0008] The technical solution of the present invention is as follows:

[0009] A multi-purpose floating body anchoring device, comprising a main anchoring device, characterized in that it also comprises an additional anchoring device, wherein the additional anchoring device comprises a weight block and a second reel for retracting and releasing the weight block:

[0010] When the floating body is anchored in a deep sea area, the weight block is lowered and suspended just below the center of gravity of the floating body;

[0011] When the buoy is anchored in a shallow sea area, the weight is lowered and sinks to the seabed;

[0012] When the floating body is sailing, the weight block is collected and hung at the bottom of the floating body.

[0013] The present invention according to the above scheme is characterized in that the main anchoring equipment includes an anchor body and a first drum for retracting and releasing the anchor body:

[0014] When the floating body is anchored in a deep sea area, the anchor body is retracted and hung at one end of the floating body;

[0015] When the floating body is anchored in a shallow sea area, the anchor body is lowered and sinks to the seabed;

[0016] When the floating body is in navigation, the anchor body is collected and hung at one end of the floating body.

[0017] The present invention according to the above scheme is characterized in that the weight block is connected to one end of the anchor cable, the other end of the anchor cable is wound around the second drum, and the anchor cable passes through the floating body.

[0018] Furthermore, the anchor cable of the weight passes through the floating body through a watertight sleeve.

[0019] Furthermore, both ends of the watertight sleeve are provided with bell mouths.

[0020] Furthermore, the diameter of the bell mouth is smaller than the size of the weight block, which can avoid the weight block being stuck in the watertight sleeve due to excessive reeling when the weight block is reeled in.

[0021] The present invention according to the above aspect is characterized in that the weight block has an inverted cone shape.

[0022] The present invention according to the above solution is characterized in that the first drum of the main anchoring equipment and the second drum of the additional anchoring equipment are connected to the same anchor windlass, and the anchor windlass is used to drive the first drum or the second drum to rotate.

[0023] The present invention according to the above scheme is characterized in that the main anchoring equipment also includes a guide wheel arranged at the edge of the floating body, and the anchor chain of the anchor body passes over the top of the guide wheel.

[0024] The present invention also provides a method for implementing a multi-purpose floating body mooring device, which adjusts the center of gravity of the entire floating body by changing the state of the additional mooring equipment:

[0025] When the floating body is anchored in a deep sea area, the liftable component of the additional anchoring equipment lowers the center of gravity, so that the center of gravity of the floating body is lowered;

[0026] When the buoy is anchored in a shallow sea area, the liftable component of the additional anchoring equipment sinks to the seabed to serve as an auxiliary anchor.

[0027] The present invention according to the above scheme is characterized in that the additional anchoring equipment includes a weight block and a second drum for retracting and releasing the weight block, the weight block is a liftable component of the additional anchoring equipment, and the center of gravity of the entire floating body is adjusted by changing the upper and lower positions of the weight block:

[0028] When the buoy is anchored in a deep sea area, the second drum rotates and lowers the weight so that the center of gravity of the weight is located directly below the center of gravity of the buoy;

[0029] When the buoy is anchored in a shallow sea area, the second drum rotates and lowers the weight, so that the weight sinks to the seabed as an auxiliary anchor and provides anchoring force.

[0030] The present invention according to the above scheme is characterized in that during the navigation of the floating body, the position of the weight block is adjusted by the second drum so that the weight block is hung at the bottom of the floating body.

[0031] The present invention according to the above scheme is characterized in that the multi-purpose floating anchoring device comprises an anchor body and a first reel for retracting and releasing the anchor body:

[0032] When the floating body is anchored in a deep sea area, the position of the anchor body is adjusted by the first reel so that the anchor body is retracted and hung at one end of the floating body;

[0033] When the floating body is anchored in a shallow sea area, the position of the anchor body is adjusted by the first drum so that the anchor body is lowered and sunk to the seabed;

[0036] The mooring device of the present invention is provided with a weight block with two purposes, and the anchor cable of the weight block penetrates the floating body. When the floating body is located in a shallow sea area, the weight block is used as an auxiliary anchor and sinks to the seabed together with the anchor body to provide additional anchor gripping force for the floating body and avoid displacement of the floating body; when the floating body is located in a deep sea area, the weight block is suspended in the water to lower the center of gravity of the floating body to reduce the swaying amplitude of the floating body caused by waves; therefore, the multifunctional mooring device provided by the present invention enables the floating body to stably float both in shallow sea areas and in deep sea areas.

[0042] In order to better understand the purpose, technical solution and technical effect of the present invention, the present invention is further explained below in conjunction with the accompanying drawings and embodiments. At the same time, it is stated that the embodiments described below are only used to explain the present invention and are not used to limit the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0044] The directions or positions indicated by terms such as “up”, “down”, “left”, “right”, “front”, “back”, “vertical”, “horizontal”, “top”, “bottom”, “inside” and “outside” are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and are not to be construed as limitations on the present technical solution.

[0045] The terms "first" and "second" are only used for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly specifying the number of technical features.

[0046] like Figure 1 to Figure 3 As shown, a multi-purpose floating body mooring device includes a main mooring device and an additional mooring device. The main mooring device includes an anchor body 2 and a first drum for retracting and releasing the anchor body 2, and the additional mooring device includes a weight block 3 and a second drum.

[0047] When the buoy 1 is anchored in a shallow sea area, the weight block 3 sinks to the seabed 8 together with the anchor body 2. At this time, the weight block 3 acts as an auxiliary anchor, providing additional anchor holding force, which can solve the problem that the buoy 1 will produce a large displacement due to wind flow load when anchored in a shallow sea area; when the buoy 1 is anchored in a deep sea area, the weight block 3 is lowered and suspended just below the center of gravity of the buoy 1, thereby lowering the center of gravity of the entire mooring device to reduce the swing amplitude of the mooring device caused by waves in the deep sea area; when the buoy is sailing, the weight block 3 is hung at the bottom of the buoy 1.

[0048] When the buoy 1 is anchored in a deep sea area, the anchor 2 is retracted and hung at one end of the buoy 1; when the buoy 1 is anchored in a shallow sea area, the anchor 2 is lowered and sunk to the seabed to provide anchoring force; when the buoy is sailing, the anchor 2 is retracted and hung at one end of the buoy 1.

[0049] In the present invention, the weight block 3 is connected to one end of the anchor cable 31, the anchor cable 31 passes through the floating body 1, and the other end of the anchor cable 31 is wound on the second drum. The weight block 3 of the present invention adopts a structural design of passing through the floating body 1 and then hanging in the water. Compared with the method of hanging the weight block 3 on the lower surface of the floating body 1 in the prior art, the present invention has three advantages:

[0050] 1. It is convenient to configure a reel (i.e., a second reel) for the weight block 3, so as to change the hanging length of the weight block 3 under the floating body 1, change the center of gravity position required by the floating body 1, and adapt to more sea conditions and different sea areas;

[0051] 2. The drum of the weight 3 can be arranged on the upper surface of the floating body 1, which is convenient for installation and management, and thus can be applied to small floating bodies 1 with narrow internal space where the drum cannot be arranged;

[0052] 3. The drum of the weight 3 can share a windlass 5 with the drum of the anchor body 2 located above the floating body 1, reducing the number of driving devices, which is beneficial to reducing the total weight of the floating body 1 and also to reducing the construction cost / renovation cost.

[0053] In this embodiment, the anchor cable 31 of the weight block 3 passes through the buoy 1 through the watertight sleeve 4. The watertight sleeve 4 can prevent seawater from seeping into the interior of the buoy 1 through the through hole of the buoy 1, providing safety protection for the structure of the anchor cable 31 of the weight block 3 passing through the buoy 1.

[0054] like Figure 1 and 4 As shown, in a preferred embodiment, both ends of the watertight sleeve 4 are provided with bell mouths 41. The upper bell mouth 41 is designed to make it smoother when the anchor cable 31 is retracted and released, and avoid the sharp corners of the opening from wearing the anchor cable 31, thereby reducing the power consumption of the anchor machine 5; the lower bell mouth 41 is designed to provide a buffer to avoid the anchor cable 31 being "broken" at the lower opening when the weight block 3 swings in extreme sea conditions, and the center of gravity of the weight block being offset too much; thereby preventing the center of gravity of the floating body from changing suddenly under the swing of the weight block 3 in extreme sea conditions, and the floating body 1 from shaking more violently, such as when the weight block 3 swings. Figure 4 As shown, the left side shows a structure in which the watertight sleeve is not provided with a bell mouth, and the right side shows a structure in which the watertight sleeve is provided with a bell mouth.

[0055] In a preferred embodiment, the weight block 3 is in the shape of an inverted cone. The structural design of the inverted cone weight block 3 has the following advantages:

[0056] 1. When the weight block 3 is needed to be used as an auxiliary anchor, during the process of lowering the weight block 3, the weight block 3 is inserted into the seabed 8 by its own weight, and the tip bottom of the weight block 3 is conducive to the rapid insertion of the weight block 3 into the seabed 8;

[0057] 2. When the weight block 3 is suspended for use, the bottom tip design is more conducive to buffering the force of waves on the weight block 3, thereby making the overall suspension assembly of the weight block 3 more stable.

[0058] In a preferred embodiment, the first drum and the second drum are connected to the same anchor windlass 5, which is used to drive the first drum or the second drum to rotate, that is, the anchor windlass 5 can control the corresponding drum to rotate according to the specific usage conditions, thereby separately performing the retracting and releasing operations of the anchor body 2 and the weight 3.

[0059] In a preferred embodiment, the multi-purpose floating body 1 mooring device is also provided with a guide wheel 6, which is arranged at the edge of the floating body 1. The guide wheel 6 is used to bypass the anchor chain 21 of the anchor body 2. Specifically, the anchor chain 21 bypasses from above the guide wheel 6 to achieve the process of retracting and releasing the anchor body 2, thereby avoiding excessive friction between the anchor chain 21 and the edge of the floating body 1, which is not conducive to the retraction and release of the anchor body 2.

[0060] The present invention also provides a method for implementing a multi-purpose floating body mooring device, which adjusts the center of gravity of the entire floating body by changing the state of the additional mooring equipment:

[0061] When the floating body 1 is anchored in a deep sea area, the liftable components of the additional anchoring equipment lower the center of gravity, so that the center of gravity of the floating body 1 is lowered;

[0062] When the buoy 1 is anchored in a shallow sea area, the raisable component of the additional anchoring equipment sinks to the seabed to serve as an auxiliary anchor.

[0063] In this embodiment, the additional anchoring equipment includes a weight block 3 and a second drum for retracting and releasing the weight block 3. The weight block 3 is a liftable component of the additional anchoring equipment. The center of gravity of the entire floating body is adjusted by changing the upper and lower positions of the weight block:

[0064] When the floating body 1 is anchored in the deep sea area, the second drum rotates and lowers the weight block so that the center of gravity of the weight block 3 is located directly below the center of gravity of the floating body 1;

[0065] When the buoy 1 is anchored in a shallow sea area, the second drum rotates and lowers the weight 3, so that the weight 3 sinks to the seabed as an auxiliary anchor and provides anchoring force.

[0066] In this embodiment, during the navigation of the floating body 1 , the position of the weight 3 is adjusted by the second drum so that the weight 3 is hung at the bottom of the floating body 1 .

[0067] The multi-purpose floating anchoring device comprises an anchor body 2 and a first reel for retracting and releasing the anchor body 2:

[0068] When the floating body 1 is anchored in the deep sea area, the position of the anchor body 2 is adjusted by the first reel so that the anchor body 2 is retracted and hung at one end of the floating body 1;

[0069] When the floating body 1 is anchored in a shallow sea area, the position of the anchor body is adjusted by the first drum so that the anchor body 2 is lowered and sunk to the seabed;

[0070] During the navigation of the floating body 1, the position of the anchor body is adjusted by the first drum so that the anchor body 2 is retracted and hung at one end of the floating body.

[0071] In summary, the structural design of the present invention is simple, practical and easy to operate. It can be used for multiple purposes with only a slight modification on the basis of traditional anchoring equipment. It can adapt to both deep water areas and shallow water areas. The modification work is small and the economy is good.

[0072] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
