A polyurethane bend for submarine communication

Abstract

This application discloses a polyurethane bender for submarine communication, belonging to the field of bender technology. It includes a tube body and a connecting mechanism. The design is novel and ingenious. When a submarine cable needs repair or replacement, only two arc-shaped blocking plates need to be pried apart. The second connector is in a movable state, and pushing it inward causes the abutment block to move outward under the pressure of the movable block. The movable block extends deep into the mounting groove. When the outside of the movable block contacts the two abutment blocks, and the movable block and pull rod are joined, pulling the second connector outward will cause the fixed block to detach from the mounting groove, allowing the mounting plate to quickly separate from the mounting groove. This shortens disassembly time, improves working efficiency, and solves the problem of needing to replace the entire bender when a submarine cable needs repair or replacement, increasing wear and shortening the bender's lifespan. This greatly enhances the practicality of the device.

Description

Technical Field

[0001] This application relates to the field of turning device technology, and more particularly to a polyurethane turning device for submarine communication. Background Technology

[0002] Submarine communication is a technical means of transnational telecommunications transmission through laying submarine cables. Modern submarine communication mainly uses optical fiber as the transmission medium, which has the characteristics of strong confidentiality and large capacity. Together with satellite communication, it constitutes the two pillars of intercontinental communication.

[0003] Polyurethane bend limiters are used in submarine cable systems to prevent excessive bending of cables and protect them from mechanical damage. Submarine cable bend reinforcements are mainly used at the connection points between submarine cables / pipes and rigid equipment, where submarine cables are prone to dynamic fatigue and bending. After installing bend reinforcements at rigid connection points, the bending stiffness of the submarine cable / pipe at that point can be improved, enhancing its resistance to bending and fatigue. Therefore, bend reinforcements are particularly suitable for the protection of rigid nodes of dynamic cables / pipes.

[0004] However, with existing technology, the connection mechanism is fixed. When the submarine cable has a problem and needs to be repaired or replaced, the entire bender needs to be replaced, which increases the wear and tear and shortens the service life of the bender.

[0005] Therefore, this application proposes a polyurethane bender for submarine communication. Utility Model Content

[0006] This application proposes a polyurethane bender for submarine communication to solve the problems mentioned in the background art. The structural design allows for easy separation of the two arc-shaped blocking plates when a submarine cable needs repair or replacement. With the second connector in a movable state, pushing the second connector inward causes the abutment block to move outward under the pressure of the movable block. The movable block extends deeper into the mounting groove. When the outside of the movable block contacts the two abutment blocks and the movable block is joined with the pull rod, pulling the second connector outward will cause the fixed block to detach from the mounting groove, allowing the mounting plate to quickly separate from the mounting groove. This shortens disassembly time, improves work efficiency, and solves the problem of needing to replace the entire bender when a submarine cable needs repair or replacement, increasing wear and shortening the bender's lifespan. This significantly enhances the practicality of the device.

[0007] To achieve the above objectives, this application adopts the following technical solution: A polyurethane bend for submarine communication includes a tube body and a connecting mechanism. The tube body is generally tapered and has a double-layer structure. The connecting mechanism includes a first connector, a second connector, an arc-shaped end plate, a plug-in assembly, and a plug-out assembly. The first connector is fixed to the tube body, and the second connector is detachably connected to the first connector. Two arc-shaped end plates are provided between the first connector and the second connector.

[0008] In a preferred embodiment, the tube body consists of an outer layer and an inner layer, with the outer layer made of polyurethane and the inner layer made of stainless steel. The conical design of the tube body effectively disperses stress. The inner stainless steel layer provides strength and corrosion resistance, while the outer polyurethane layer enhances wear resistance and impact resistance, thereby improving the practicality of the device.

[0009] In one preferred embodiment, the plug-in assembly includes a mounting slot, a mounting plate, a movable rod, a stop block, a spring, a mounting block, a pull rod, a fixing block, and a movable block; By setting up a connection mechanism, disassembly time is shortened, work efficiency is improved, and the problem of having to replace the entire bender when submarine cables need repair or replacement is solved, which increases wear and shortens the service life of the bender, is solved, thereby improving the practicality of the device.

[0010] In a preferred embodiment, each mounting slot is formed inside the first connector, and two mounting plates are fixedly connected inside each mounting slot. A movable rod is slidably connected inside each mounting plate, and a stop block is fixedly connected to one end of each movable rod. When the fixing block and the abutment block come into contact, the abutment block opens under pressure, allowing the fixing block to extend deeper into the mounting groove, thereby improving the practicality of the device.

[0011] In a preferred embodiment, each of the movable rods is provided with a spring on its exterior, and one end of each spring is fixed to the mounting plate and the other end is fixed to the movable rod; By using the spring to move the movable rod within the mounting plate, the connecting block is engaged in the gap between the fixed block and the movable block, thereby improving the practicality of the device.

[0012] In a preferred embodiment, each of the mounting blocks is fixedly connected to the second connector, a pull rod is fixedly connected to the side of each mounting block away from the second connector, and a fixing block is fixedly connected to the end of each pull rod away from the mounting block; By extending the movable block deep into the mounting groove, the movable block and the pull rod come together when the outside of the movable block contacts the two abutments, thereby improving the practicality of the device.

[0013] In a preferred embodiment, each of the pull rods is slidably connected to a movable block on its exterior, and each of the abutments extends between the fixed block and the movable block; By pulling the second connector outward, the fixing block will be disengaged from the mounting slot, allowing the mounting plate to quickly disconnect from the mounting slot, thereby improving the practicality of the device.

[0014] In a preferred embodiment, the plug-in assembly includes slots and plugs, with two slots each opened inside one of the arc-shaped blocking plates, and two plugs each fixedly connected to the other arc-shaped blocking plate, and both plugs inserted into the slots. By fitting two arc-shaped end plates into the gap between the first connector and the second connector, the two arc-shaped end plates are inserted into the slots on the other arc-shaped end plate through a plug on one end plate. The plug uses a specially structured spring plate with a certain elastic force, which allows the protrusion on the plug to engage with the groove in the slot to form a snap-fit ​​relationship, thereby improving the practicality of the device.

[0015] The beneficial effects of this application are: 1. This polyurethane bender for submarine communication has a structural design that allows for easy repair or replacement of submarine cables. When a problem arises, the two arc-shaped blocking plates are first pried apart, leaving the second connector in a movable state. Pushing the second connector inward causes the abutment block to move outward under the pressure of the movable block, extending the movable block deeper into the mounting groove. When the outer surface of the movable block contacts the two abutment blocks and the movable block is joined with the pull rod, pulling the second connector outward will cause the fixed block to detach from the mounting groove, allowing the mounting plate to quickly separate from the mounting groove. This shortens disassembly time, improves work efficiency, and solves the problem of needing to replace the entire bender when a problem arises with a submarine cable, increasing wear and shortening the bender's lifespan. This significantly enhances the practicality of the device. 2. This polyurethane bender for submarine communication uses two arc-shaped blocking plates fitted into the gap between the first connector and the second connector. The two arc-shaped blocking plates are inserted into the slots on the other arc-shaped blocking plate by a plug on one of the arc-shaped blocking plates. The plug uses a specially structured spring sheet with a certain elastic force, so that the protrusion on the plug is engaged in the groove in the slot to form a snap-fit ​​relationship. The first connector and the second connector are fixed and not easy to fall off, which greatly improves the practicality of the device. Attached Figure Description

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] Reference Figure 1-4 A polyurethane bend for submarine communication includes a tube body 1 and a connecting mechanism 3. The tube body 1 is generally tapered and has a double-layer structure. The connecting mechanism 3 includes a first connector 31, a second connector 32, an arc-shaped blocking plate 33, a plug-in assembly 34, and a plug-out assembly 35. The first connector 31 is fixed to the tube body 1, and the second connector 32 is detachably connected to the first connector 31. Two arc-shaped blocking plates 33 are provided between the first connector 31 and the second connector 32.

[0020] Reference Figure 1-2 The tube body 1 is divided into an outer layer 11 and an inner layer 12. The outer layer 11 is made of polyurethane, and the inner layer 12 is made of stainless steel. The overall conical design of the tube body 1 can effectively disperse stress. The stainless steel inner layer 12 can provide strength and corrosion resistance, while the polyurethane outer layer 11 enhances wear resistance and impact resistance, thereby improving the practicality of the device.

[0021] Reference Figure 2-3 The plug-in assembly 34 includes a mounting slot 341, a mounting plate 342, a movable rod 343, a stop block 344, a spring 345, a mounting block 346, a pull rod 347, a fixing block 348, and a movable block 349. By setting up the connection mechanism 3, the disassembly time is shortened, the working efficiency is improved, and the problem of having to replace the entire turning device when the submarine cable needs to be repaired or replaced is solved, which increases wear and shortens the service life of the turning device, thereby improving the practicality of the device.

[0022] Reference Figure 1-4Each mounting slot 341 is formed inside the first connector 31. Two mounting plates 342 are fixedly connected inside each mounting slot 341. A movable rod 343 is slidably connected inside each mounting plate 342. A stop block 344 is fixedly connected to one end of each movable rod 343. When the fixed block 348 abuts against the stop block 344, the stop block 344 opens under pressure, causing the fixed block 348 to extend deeper into the mounting slot 341, thereby improving the practicality of the device.

[0023] Reference Figure 2-3 Each movable rod 343 is equipped with a spring 345 on its exterior, and one end of each spring 345 is fixed to the mounting plate 342, while the other end is fixed to the movable rod 343. Under the action of the spring 345, the movable rod 343 is driven to move within the mounting plate 342, causing the abutment 344 connected to it to be engaged in the gap between the fixed block 348 and the movable block 349, thereby improving the practicality of the device.

[0024] Reference Figure 1-4 Each mounting block 346 is fixedly connected to the second connector 32. A pull rod 347 is fixedly connected to the side of each mounting block 346 away from the second connector 32. A fixing block 348 is fixedly connected to the end of each pull rod 347 away from the mounting block 346. The movable block 349 extends into the mounting groove 341. When the outside of the movable block 349 contacts the two abutments 344, the movable block 349 and the pull rod 347 will come together, thereby improving the practicality of the device.

[0025] Reference Figure 1-4 Each pull rod 347 is slidably connected to a movable block 349 on its outside, and each abutment 344 extends between the fixed block 348 and the movable block 349. By pulling the second connector 32 outward, the fixed block 348 will be disengaged from the mounting groove 341, so that the mounting plate 342 and the mounting groove 341 are quickly disconnected, thereby improving the practicality of the device.

[0026] Reference Figure 1-4 The plug-in assembly 35 includes slots 351 and plugs 352. Both slots 351 are located inside one of the arc-shaped blocking plates 33, and both plugs 352 are fixedly connected to the other arc-shaped blocking plate 33. Both plugs 352 are inserted into the slots 351. By fitting the two arc-shaped blocking plates 33 into the gap between the first connector 31 and the second connector 32, the two arc-shaped blocking plates 33 are inserted into the slots 351 on the other arc-shaped blocking plate 33 through the plugs 352 on one arc-shaped blocking plate 33. The plugs 352 are made of spring sheets with a special structure and have a certain elastic force, so that the protrusions on the plugs 352 are engaged in the grooves in the slots 351 to form a snap-fit ​​relationship, thereby improving the practicality of the device.

[0027] Working principle: During connection, the fixing blocks 348 on the second connector 32 are aligned with the mounting grooves 341 and inserted. When the fixing blocks 348 abut against the abutment blocks 344, the abutment blocks 344 open under pressure, allowing the fixing blocks 348 to extend deeper into the mounting grooves 341. When the abutment blocks 344 overlap with the gap between the fixing blocks 348 and the movable blocks 349, the movable rod 343 moves within the mounting plate 342 under the action of the spring 345, causing the abutment blocks 344 connected to them to be engaged in the gap between the fixing blocks 348 and the movable blocks 349. The first connector 31 and the second connector 32 are then connected. Two arc-shaped blocking plates 33 are then fitted into the gap between the first connector 31 and the second connector 32. The two arc-shaped blocking plates 33 are inserted into the slots 351 on the other arc-shaped blocking plate 33 via insert blocks 352 on one arc-shaped blocking plate 33. The insert blocks 352 use a specially structured spring sheet with a certain elastic force, allowing... The protrusion on the insert 352 engages with the groove in the slot 351 to form a snap-fit ​​connection. The first connector 31 and the second connector 32 are fixed and not easily detached. With this structural design, when the submarine cable needs repair or replacement, it is only necessary to first pry open the two arc-shaped blocking plates 33 to separate them. The second connector 32 is in an active state and can be pushed inward, causing the abutment block 344 to move outward under the pressure of the movable block 349. The movable block 349 extends deep into the mounting groove 341. When the outside of the movable block 349 contacts the two abutment blocks 344, and the movable block 349 and the pull rod 347 are together, pulling the second connector 32 outward will cause the fixed block 348 to disengage from the mounting groove 341, so that the mounting plate 342 and the mounting groove 341 are quickly disconnected, shortening the disassembly time, improving the working efficiency, and solving the problem that when the submarine cable needs repair or replacement, the entire turning device needs to be replaced, increasing wear and shortening the service life of the turning device.
