Description

Technical Field

[0001] This utility model relates to the field of underwater weapon supporting equipment technology, and in particular to a chemical fiber tethering cable for fixing underwater weapon mine bodies. Background Technology

[0002] As a core component connecting the mine body to the seabed fixed base or carrier, the mooring cable is crucial for ensuring the stable deployment, precise positioning, and reliable operation of underwater weapons. It must withstand the high pressure of the deep sea, the impact of shallow water currents, seawater corrosion, and long-term loads, and has stringent requirements for structural adaptability, pressure and impact resistance, connection firmness, and durability.

[0003] Currently, underwater weapon mooring cables mainly use steel wire ropes or ordinary chemical fiber braided ropes. Structurally, they are mostly integrated designs with a single braided layer. The connection methods are mainly bolt fastening, welding fixation, or simple buckle connection. Among them, steel wire ropes have the problems of heavy weight, easy corrosion, and poor deployment flexibility, while ordinary chemical fiber braided ropes are prone to deformation under the high pressure of the deep sea and easy to loosen in the strong currents of the shallow sea. Moreover, the existing integrated structure has not been optimized for the different working conditions of deep and shallow seas, and the connection methods are either inconvenient to disassemble or prone to loosening under complex underwater working conditions. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a chemical fiber mooring cable for fixing underwater weapon mines, so as to solve the problems that existing underwater weapon mooring cables are mostly steel wire ropes or ordinary chemical fiber braided ropes, with a single structure that is not suitable for deep and shallow seas, and the connection method is either inconvenient to disassemble or easy to loosen.

[0005] Based on the above objectives, this utility model provides a chemical fiber tethering cable for fixing underwater weapon mine bodies, including a deep-sea section, a connecting section, and a shallow-sea section. The deep-sea section and the shallow-sea section are detachably connected through the connecting section. The deep-sea section includes a deep-sea ring sleeve, and the deep-sea ring sleeve has a deep-sea braided layer arranged in a ring shape inside. The twist of the deep-sea braided layer is 10-15mm, which is suitable for the high-pressure environment of the deep sea. The shallow sea section includes a shallow sea ring, within which a shallow sea woven layer is arranged in a ring-shaped array. The twist of the shallow sea woven layer is 20-25mm, which is suitable for the shallow sea current impact environment. The connecting part includes two connecting ring sleeves, which are rotatably mounted at the ends of the shallow sea ring sleeve and the deep sea ring sleeve respectively via bearings. The connecting ring sleeves have a built-in cylindrical metal elastic skeleton and an outer woven carbon fiber reinforcement layer to improve bending strength. The two connecting ring sleeves are axially locked together by a locking component.

[0006] Preferably, both the deep-sea braided layer and the shallow-sea braided layer include multiple braided ropes and rope cores, with the braided ropes twisting along the rope cores in a spiral shape as they rise. Among them, the braided rope of the deep-sea braided layer is also embedded with rigid supports, which are arranged in a spiral array along the braided rope to enhance the deep-sea pressure resistance.

[0007] Preferably, the engaging component includes a first insert rod fixedly installed at one end of one connecting ring sleeve, and a first slot opened at the other end of the connecting ring sleeve; a first insert ring is slidably connected in the first slot, and after the first insert rod is inserted into the first slot, its end abuts against the first insert ring and drives the first insert ring to slide along the axial direction of the slot.

[0008] Preferably, the inner wall of the first slot is provided with a first annular groove, a first airbag is fixed in the first annular groove, and a first locking bead in a ring array is embedded in the side of the first airbag facing the center of the first slot. The outer wall of the first insertion rod is provided with a first slot that is adapted to the first locking bead; When the first insert is fully inserted into the first slot, the first insert ring compresses the first airbag to inflate it, driving the first retaining bead to embed into the first retaining groove to achieve radial engagement.

[0009] Preferably, a second slot is provided inside the connecting ring sleeve, which is coaxially connected to the first slot. The second slot is located on the side away from the other connecting ring sleeve, and a second insert rod is fixed at the bottom of the slot. A butterfly spring is sleeved on the second insert rod, and the two ends of the butterfly spring abut against the bottom of the second slot and the first insert ring, respectively, to provide a preload force to the first insert ring toward the first insert rod.

[0010] Preferably, a third slot corresponding to the second insert rod is provided in the other connecting ring sleeve. When the first insert rod is inserted into the first slot, the second insert rod is simultaneously inserted into the third slot to form a dual axial positioning.

[0011] Preferably, the end of the second insertion rod is provided with a second annular groove, and the bottom of the third slot is fixed with a compression frame. A compression airbag is sleeved on the compression frame, and a second retaining ring adapted to the second annular groove is fixed at its end. When the second insertion rod is inserted into the third slot and abuts against the compression airbag, the compression airbag expands and pushes the second retaining ring to deform elastically and embed into the second annular groove, thereby achieving radial locking between the second insertion rod and the third slot.

[0012] The beneficial effects of this utility model are: This mooring cable features a segmented structure designed for different water conditions in deep and shallow seas. The deep-sea section uses a 10-15mm low-twist deep-sea braided layer, combined with a rigid support with a spiral array inside the braided rope, to enhance structural stability under high pressure and prevent the braided layer from collapsing. The shallow-sea section uses a 20-25mm high-twist shallow-sea braided layer to improve resistance to water flow impact and fatigue resistance, solving the problem that traditional single structures cannot simultaneously meet the requirements of pressure resistance and impact resistance, and is suitable for deployment in all water depths.

[0013] The mooring cable is installed by rotating the connection part through bearings, which releases the torsional stress caused by water flow and avoids local stress concentration. The locking part adopts double axial positioning with the first and second insert rods, and is pre-tightened and locked by a butterfly spring to prevent loosening and falling off under high pressure and vibration.

[0019] like Figures 1 to 7 As shown, a chemical fiber tethering cable for fixing underwater weapon mines includes a deep-sea section 1, a connecting section 2, and a shallow-sea section 3. The deep-sea section 1 and the shallow-sea section 3 are detachably connected by the connecting section 2. It can be flexibly assembled or disassembled according to the deployment water depth to adapt to the rapid deployment and maintenance needs of different combat scenarios. The deep-sea section 1 includes a deep-sea ring 11, which is woven from ultra-high molecular weight polyethylene fiber. This material has both high pressure resistance (≥10MPa) and seawater corrosion resistance. Its inner wall has 6-8 sets of deep-sea braided layers 12 arranged in a ring. Each set of deep-sea braided layers 12 is equidistantly distributed along the axial direction of the ring and the adjacent layers are tightly attached to form a closed-loop force structure to evenly distribute the deep-sea pressure. The deep-sea ring 11 contains a ring-shaped array of deep-sea braided layers 12. The twist of the deep-sea braided layers 12 is 10-15mm. The dense twisting enhances the structural compactness. The braiding angle is 55°-60° to enhance tensile strength and adapt to the high-pressure environment of the deep sea. like Figure 2 As shown, the shallow sea section 3 includes a shallow sea ring 31, within which a ring array of shallow sea braided layers 32 is arranged. The shallow sea ring 31 is made of high-toughness nylon fiber, which has excellent fatigue resistance (≥100,000 bends without breakage). Its inner wall has 4-6 groups of shallow sea braided layers 32 arranged in a ring array. A gap of 0.5-1mm is reserved between each group of shallow sea braided layers 32 to improve the buffering performance under water flow impact. The twist of the shallow sea braided layers 32 is 20-25mm. The overall flexibility is enhanced by the relatively loose twist. The braiding angle is 40°-45° to improve the anti-sway ability and adapt to the shallow sea water flow impact environment. The braided rope 121 of the shallow sea braided layer 32 adopts a pure fiber structure without rigid support 123, which can undergo elastic deformation within a range of ±10° under water flow impact, reducing local stress concentration and adapting to the shallow sea water flow impact environment of 0-500 meters (withstanding water flow velocity ≤5m / s). like Figure 3 As shown, the connecting part 2 includes two connecting ring sleeves 21. The two connecting ring sleeves 21 are respectively rotatably installed at the ends of the shallow sea ring sleeve 31 and the deep sea ring sleeve 11 via bearings, which can achieve 360° free rotation to release the torsional stress under the action of water flow (maximum bearing torque ≥200N・m). The connecting ring sleeve 21 has a built-in cylindrical metal elastic skeleton and an outer woven carbon fiber reinforcement layer to improve the bending strength. The two connecting ring sleeves 21 are axially locked together by a locking member 22. After locking, the overall axial bearing capacity is ≥50kN, which meets the load requirements for fixing the mine body.

[0020] Furthermore, such as Figure 3 As shown, both the deep-sea braided layer 12 and the shallow-sea braided layer 32 include multiple braided ropes 121 and rope cores 122. The braided ropes 121 twist along the rope cores 122 and rise in a spiral shape with a spiral angle of 15°-20° to balance the braiding tightness and tensile strength. Among them, the braided rope 121 of the deep-sea braided layer 12 is also embedded with a rigid support 123. The rigid support 123 is arranged in a spiral array along the braided rope 121 (the pitch is consistent with the twist pitch of the braided rope 121). The two ends of the rigid support 123 are fixed to the ends of the braided rope 121, forming a fiber-metal composite reinforcement structure, which can improve the local pressure resistance in the deep-sea environment by more than 30% and effectively prevent the braided rope 121 from radially deforming due to high pressure.

[0021] Furthermore, such as Figure 4 As shown, the engaging component 22 includes a first insert 221 fixedly installed at the end of one of the connecting ring sleeves 21, and a first slot 222 opened at the end of the other connecting ring sleeve 21; a first insert ring 223 is slidably connected in the first slot 222. After the first insert 221 is inserted into the first slot 222, its end abuts against the first insert ring 223 and drives the first insert ring 223 to slide along the slot axis. When the first insert 221 is inserted into the first slot 222, its end precisely abuts against the end face of the first insert ring 223 and drives the first insert ring 223 to slide smoothly along the slot axis. The sliding stroke matches the insertion depth of the first insert 221.

[0022] Furthermore, such as Figure 5 As shown, the inner wall of the first slot 222 is provided with a first annular groove 224, and a first airbag 225 is fixed in the first annular groove 224. The first airbag 225 is inlaid with a first locking bead 226 arranged in a ring on the side facing the center of the first slot 222. The outer wall of the first insertion rod 221 is provided with a first locking groove 227 that is adapted to the first locking bead 226. When the first insert rod 221 is fully inserted into the first slot 222, the first insert ring 223 squeezes the first airbag 225 to increase its internal air pressure and expand radially, pushing the first locking bead 226 to move radially along the ring groove and accurately embed into the first locking slot 227 to achieve radial engagement.

[0023] Furthermore, such as Figure 6 As shown, a second slot 228 is provided inside the connecting ring sleeve 21, which is coaxially connected to the first slot 222. The second slot 228 is located on the side away from the other connecting ring sleeve 21, and a second insert rod 229 is fixed at the bottom of the slot. A butterfly spring 230 is sleeved on the second insert rod 229. The two ends of the butterfly spring 230 abut against the bottom of the second slot 228 and the first insert ring 223, respectively, which can continuously provide a pushing force to the first insert ring 223 toward the first insert rod 221, ensuring that the first insert ring 223 always tightly squeezes the first airbag 225, and avoids loosening due to vibration or water pressure fluctuations.

[0024] Furthermore, such as Figure 7 As shown, another connecting ring sleeve 21 has a third slot 231 that is coaxial with the second insert 229. When the first insert 221 is inserted into the first slot 222, the second insert 229 is simultaneously inserted into the third slot 231 to form a double axial positioning.

[0025] Furthermore, such as Figure 7 As shown, the end of the second insertion rod 229 is provided with a second annular groove 232, and the bottom of the third slot 231 is fixed with a compression frame 233. A compression airbag 234 is sleeved on the compression frame 233, and its end is fixed with a second retaining ring 235 that is adapted to the second annular groove 232. When the second insertion rod 229 is inserted into the third slot 231 and abuts against the compression airbag 234, the compression airbag 234 expands and pushes the second retaining ring 235 to elastically deform and embed into the second annular groove 232, thereby achieving radial locking between the second insertion rod 229 and the third slot 231.

[0026] Working principle: The chemical fiber tethering cable for fixing the underwater weapon mine body is based on a segmented, adaptable, and collaborative locking core design. It achieves stable fixation in different water depth environments through differentiated structures and components: the deep-sea section 1 uses a ring made of ultra-high molecular weight polyethylene fiber with a densely woven layer of small twist, combined with a helical rigid support 123 inside the braided rope 121 to resist high pressure and prevent structural collapse; the shallow-sea section 3 uses a high-toughness nylon ring with a loosely woven layer of large twist, which buffers the impact of water flow and reduces stress concentration through the interlayer gaps and elastic deformation of the pure fiber structure; the connecting section 2 achieves 360° free rotation through bearings to release torsional stress. During docking, the first insertion rod 221 pushes the first insertion ring 223 to squeeze the airbag 234, driving the locking ball to embed into the slot to complete the first-level radial engagement. At the same time, the second insertion rod 229 is inserted into the third slot 231, and the squeezing airbag 234 pushes the locking ring to embed into the ring groove to achieve the second-level locking. The dual axial positioning and radial engagement work together to ensure the reliability of the connection, ultimately achieving flexible deployment and stable fixation of the mine body in deep and shallow sea environments.
