Description

Technical Field

[0001] The utility model relates to the technical field of underwater salvage equipment, in particular to a device for towing a bottom-crossing steel cable for salvaging a sunken ship. Background Art

[0002] In existing shipwreck salvage operations, the primary method for towing a bottom-crossing cable is to use a thin guide cable. This guide cable must pass through a pre-prepared jack hole on the seabed, a hole designed specifically for salvage operations. A thicker bottom-crossing cable is connected to the end of the guide cable. As the guide cable is pulled through the jack hole and reaches the other side of the shipwreck, the bottom-crossing cable is towed.

[0003] While this traditional over-the-bottom cable-dragging method is technically capable of laying cables, it has some significant limitations. The most prominent issue is that this method can only thread one cable at a time. This means that if multiple cables need to be laid to enhance salvage stability and efficiency, the entire cable-threading process must be repeated multiple times. This not only significantly increases construction costs but also significantly prolongs underwater operations. In this scenario, divers and salvage equipment must perform multiple underwater maneuvers, which is not only inefficient but also increases diver safety risks. Furthermore, since only one cable can be threaded at a time, this limits the progress of salvage operations. Especially in emergency or complex situations, this inefficient method can seriously impact the smooth progress of the salvage mission.

[0004] Therefore, the industry urgently needs a new technology or method that can achieve the towing of multiple bottom cables at one time, thereby significantly improving operational efficiency, reducing costs, and shortening underwater operation time to improve the safety and economic benefits of the overall salvage operation.

[0035] A device for towing a bottom-crossing steel cable for shipwreck salvage comprises a main submarine trenching unit 1, a guide unit, an auxiliary trenching unit, and at least two bottom-crossing steel cable towing units:

[0036] Subsea trenching main unit 1;

[0037] A guide unit, the guide unit being installed at the head of the seabed trenching main unit 1;

[0038] Auxiliary trenching units, which are installed on the seabed trenching main unit 1 and located on both sides of the guide unit;

[0039] At least two bottom-crossing steel cable traction units are installed on both sides of the seabed trenching main unit 1.

[0040] The present embodiment utilizes a submarine trenching main unit 1 connected to multiple bottom-crossing cable traction units, enabling the simultaneous towing of multiple bottom-crossing cables. This significantly improves the efficiency of shipwreck salvage operations, reduces the number of repetitive operations, and shortens the overall construction period. This device reduces the manpower, material resources, and time required during the construction process.

[0041] The present embodiment utilizes a submarine trenching main unit 1 connected to multiple bottom-crossing cable traction units, enabling the simultaneous towing of multiple bottom-crossing cables. This significantly improves the efficiency of shipwreck salvage operations, reduces the number of repetitive operations, and shortens the overall construction period. This device reduces the manpower, material resources, and time required during the construction process. This effectively controls the high costs of underwater operations and improves the economic efficiency of salvage projects.

[0042] It is worth mentioning that, in this embodiment, the number of bottom cable traction units is mainly introduced as two. In fact, the number of bottom cable traction units can be three or even more, which also falls within the protection scope of this application.

[0043] like Figure 2 As shown, Figure 2 It is a structural schematic diagram of a submarine trenching main unit 1 provided in an embodiment of the present application.

[0044] In some embodiments of the present application, the submarine trenching main unit includes a main arm 11 and at least two extension arms 12, the head end of each extension arm 12 is connected to the side wall of the main arm 11, the extension arm 12 extends from the main arm 11 to the side and rear, and the angle between the main arm 11 and the extension arm 12 is an acute angle.

[0045] In this embodiment, the combined design of the main boom 11 and extension boom 12 increases the contact area and digging force of the trenching machine, making submarine trenching operations more efficient and enabling the rapid creation of a trench suitable for the passage of a steel cable. The lateral and rearward placement of the extension boom 12 effectively reduces soil resistance encountered during trenching, making the trenching process smoother and reducing energy consumption. The presence of the extension boom 12 enables the trenching unit to achieve deeper excavation depths and wider trench widths, meeting the requirements of various shipwreck salvage operations.

[0046] In some embodiments of the present application, the guide unit includes a guide drill bit 2, which is installed on the head of the main arm 11 and is used for expanding the hole and guiding the guide cable.

[0047] In this embodiment, the pilot drill bit 2, mounted on the head of the main arm 11, precisely controls the direction of the guide cable's installation, ensuring it follows the intended path and minimizing operational difficulties caused by directional deviations. The pilot drill bit 2 has both drilling and reaming functions, further expanding the hole in the created trench to provide more space for subsequent cable installation and ensure smooth cable passage.

[0048] In some embodiments of the present application, the guide unit includes a guide cable eye 3 , which is installed at the head of the main arm 11 for fixing the guide cable.

[0049] In this embodiment, the guide cable lifting ring 3 can stably fix the guide cable to prevent it from moving or loosening during operation, thereby ensuring the accurate position of the guide cable on the seabed.

[0050] like Figure 3 As shown, Figure 3 It is a structural schematic diagram of a mud flushing nozzle 5 provided in an embodiment of the present application.

[0051] In some embodiments of the present application, the auxiliary trenching unit includes a trenching tool 4, which is installed on the extension arm 12 with the blade facing forward and is used for cutting seabed geology.

[0052] In this embodiment, the trenching cutter 4 has its blade facing forward, directly facing the seabed geology, enabling efficient cutting and accelerating the trenching process. By cutting the seabed geology, the trenching cutter 4 can reduce the resistance of the seabed soil to the seabed trenching main unit 1, making the trenching operation smoother.

[0053] In some embodiments of the present application, the auxiliary trenching unit further includes a mud flushing nozzle 5 , which is mounted on the extension arm 12 and opens forward, and is used for impacting and removing seabed geology.

[0054] In this embodiment, by providing a trenching tool 4 and a mud flushing nozzle 5, the hard soil on the seabed can be quickly loosened and removed, so that the device can smoothly pass through the shipwreck and sit on the seabed; the use of the mud flushing nozzle 5 can reduce the resistance of the seabed soil to the seabed trenching main unit 1, thereby improving the efficiency of the trenching operation.

[0055] In some embodiments of the present application, the mud flushing nozzles 5 on the two extension arms 12 are symmetrically distributed, the trenching tools 4 on the two extension arms 12 are symmetrically distributed, and the mud flushing nozzles 5 and the trenching tools 4 on the same extension arm 12 are staggered and spaced apart.

[0056] In this embodiment, the symmetrically distributed mud flushing nozzles 5 and trenching cutters 4 can simultaneously act on the seabed geology, reducing operation time and improving overall efficiency. The symmetrical distribution design ensures balanced and stable operation, reducing imbalance problems caused by excessive work intensity on one side. The staggered distribution design helps minimize disturbance to the seabed geology and avoids excessive damage caused by continuous scouring or cutting.

[0057] In some embodiments of the present application, the auxiliary ditching unit further includes a high-pressure pipe 6 , which is installed at the tail of the main arm 11 and is respectively connected to the multiple mud flushing nozzles 5 .

[0058] In this embodiment, the high-pressure pipe 6 is used to deliver high-pressure water to the mud flushing nozzle 5. The internal flow channel of the submarine trenching main unit 1 and the tail pipe form a water supply, which can realize the water supply to the mud flushing nozzle 5 and form a jet to remove the hard seabed.

[0059] like Figure 4 As shown, Figure 4 This is a structural schematic diagram of a bottom cable traction unit provided in an embodiment of the present application.

[0060] In some embodiments of the present application, the bottom cable opening traction unit includes a traction arm 7 , and a side wall of the traction arm 7 is connected to the end of the extension arm 12 .

[0061] In this embodiment, the integrated design allows the operator to control trenching and cable traction simultaneously, reducing the complexity and difficulty of the operation.

[0062] In some embodiments of the present application, the bottom cable opening traction unit further includes a bottom cable eye 8 , and the bottom cable eye 8 is installed at the tail of the traction arm 7 .

[0063] In this embodiment, the bottom cable eye 8 is located at the tail end of the traction arm 7, which can more effectively secure and pull the bottom cable, ensuring its stable laying on the seabed. By securing the bottom cable, it can reduce the risk of collision and friction with seabed obstacles or shipwrecks during seabed operations, reducing the risk of damage to the bottom cable.

[0064] Compared with the existing technology, the technical solution provided by this application brings the following beneficial technical effects:

[0065] The present embodiment utilizes a submarine trenching main unit 1 connected to multiple bottom-crossing cable traction units, enabling the simultaneous towing of multiple bottom-crossing cables. This significantly improves the efficiency of shipwreck salvage operations, reduces the number of repetitive operations, and shortens the overall construction period. This device reduces the manpower, material resources, and time required during the construction process. This effectively controls the high costs of underwater operations and improves the economic efficiency of salvage projects.
