Description

Technical Field

[0001] The invention relates to the technical field of optical cables, in particular to a butterfly optical cable with an impact-resistant structure and an installation pipeline thereof. Background Art

[0002] Optical cable, whose full name is fiber optic cable, is a communication line that uses light to transmit data in fibers made of glass or plastic. Compared with traditional copper cables, optical cables have significant advantages such as fast transmission speed, low signal attenuation, strong resistance to electromagnetic interference, and large data capacity. They are an important part of modern communication network infrastructure. The name of the butterfly optical cable comes from its flat shape and the design of the reinforcement. It is named because its cross-section looks like the wings of a butterfly. The existing butterfly optical cable is generally composed of only optical fiber, reinforcement and sheath, in which the optical fiber is used to transmit optical signals, the reinforcement is used to improve the bending resistance of the optical cable, and the sheath is used to provide protection for the optical fiber. However, because the existing sheath is generally composed of only one layer of rubber, this structure is easily damaged when subjected to large shear stress and impact force, and cannot provide sufficient protection for the optical fiber. Once the optical fiber is damaged, the information transmission it is responsible for will be interrupted immediately, seriously affecting the timely transmission of information.

[0014] Beneficial effect: When the outer rubber sleeve is impacted, the present invention utilizes the mechanical property that the viscosity of the shear thickening fluid increases with the stress it is subjected to, so that the shear thickening fluid resists the impact, thereby protecting the armor skin.

[0015] By arranging crisscross fibers on the inner rubber sleeve and the outer rubber sleeve, the toughness of the inner rubber sleeve and the outer rubber sleeve is increased, and the fiber density along the axis of the inner rubber sleeve and the outer rubber sleeve is made smaller than the fiber density perpendicular to the axis of the two, so that when the outer rubber sleeve is squeezed, the squeezed part of the outer rubber sleeve extends along the axis, thereby resisting the squeezing of the outer rubber sleeve.

[0016] By clamping the optical cable with two adjacent clamps and dragging the optical cable, the workload of laying the optical cable in the pipeline is reduced and the efficiency of laying the optical cable in the pipeline is improved. In addition, multiple sets of clamps are used to clamp the part of the optical cable entering the pipeline to avoid the optical cable being distributed randomly in the pipeline, which affects the laying and maintenance.

DETAILED DESCRIPTION

[0019] It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] Existing sheaths are generally composed of only one layer of rubber. This structure is very easy to be damaged when subjected to large shear stress and impact force, and cannot provide sufficient protection for the optical fiber.

[0021] Embodiment 1: A butterfly optical cable with an impact-resistant structure, such as Figure 1-Figure 4As shown, it includes an optical fiber 1, the outer sleeve of the optical fiber 1 is provided with a butterfly sheath 101, the butterfly sheath 101 is used to protect the optical fiber 1, and two reinforcing members 102 are arranged in the butterfly sheath 101, which are symmetrically distributed on the left and right. The outer sleeve of the butterfly sheath 101 is provided with a buffer sleeve 103, and the buffer sleeve 103 is made of elastic material and is used to buffer the impact on the optical cable armor skin 2, and reduce the impact force transmitted to the adjacent butterfly sheath 101. The outer sleeve of the buffer sleeve 103 is provided with an armor skin 2, and the armor skin 2 is made of metal material, which is used to act as a hardness for the buffer sleeve 103. The outer shell of the armor skin 2 is provided with an inner rubber sleeve 3, and the outer side of the inner rubber sleeve 3 is fixed with a number of spacer rings 4 evenly distributed along its axis. The spacer rings 4 are made of hard material and are used to resist impact and extrusion. The outer sides of the evenly distributed spacer rings 4 are jointly provided with an outer rubber sleeve 5. The inner rubber sleeve 3, the outer rubber sleeve 5 and the two adjacent spacer rings 4 form a cavity together. The cavity is filled with fluid, and the fluid is used to disperse the local pressure of the outer rubber sleeve 5 to the two spacer rings 4 adjacent to the cavity, the part of the inner rubber sleeve 3 adjacent to the cavity and the outer The rubber sleeve 5 is adjacent to the cavity except for the pressure-bearing part, thereby reducing the pressure transmitted to the armor skin 2 by the outer rubber sleeve 5. The fluid is a shear thickening fluid (a non-Newtonian fluid, which exhibits a high viscosity (i.e., hardness) when it is subjected to a large shear stress, such as corn starch paste), which is used to resist rapid impact and disperse the extrusion force. The inner rubber sleeve 3 and the outer rubber sleeve 5 are both provided with fibers along the axes of the two and perpendicular to the axes of the two. The fibers are used to increase the toughness of the inner rubber sleeve 3 and the outer rubber sleeve 5, and the fiber density perpendicular to the axes of the two is greater than that along the axes of the two. The fiber density of the axis makes the toughness of the inner rubber sleeve 3 and the outer rubber sleeve 5 perpendicular to the axis direction of the two greater than the toughness along the axis direction of the two. At this time, when the outer rubber sleeve 5 is squeezed, the fluid in the cavity adjacent to the compressed part is squeezed and flows, and the pressure acts on the inner wall of the cavity. At this time, it is difficult for the outer rubber sleeve 5 to expand in all directions, and it is easier to deform along the axis direction. Therefore, the fluid pushes the two separation rings 4 adjacent to the cavity to move in opposite directions, so that the outer rubber sleeve 5 is stretched along its axis, thereby resisting the squeezing of the outer rubber sleeve 5.

[0022] When the optical cable is impacted during use, take a brick falling on the optical cable as an example. The brick falls on the outer rubber sleeve 5 and the outer rubber sleeve 5 is deformed by the impact. The upper side of the outer rubber sleeve 5 is concave downward. The shear thickening fluid in the cavity adjacent to the position where the outer rubber sleeve 5 is hit is subjected to rapid impact and exhibits hard properties, thereby resisting the impact force generated by the brick falling, and preventing the optical cable from being damaged by the impact. When the outer rubber sleeve 5 is squeezed (non-rapid impact), the outer rubber sleeve 5 is squeezed and deformed, and the shear thickening fluid in the cavity adjacent to the squeezed position is squeezed to flow, and the shear thickening fluid pushes the two adjacent separation rings 4 to move in opposite directions. At this time, because the fiber density on the inner rubber sleeve 3 and the outer rubber sleeve 5 perpendicular to the axis of the two is greater than the fiber density along the axis of the two, the inner rubber sleeve 3 and the outer rubber sleeve 5 are stretched in the direction along the axis of the two, and the pressure in the surrounding direction makes it difficult for the outer rubber sleeve 5 near the cavity to expand outward. At this time, the outer rubber sleeve 5 is pulled along its axis, and this pulling will resist the squeezing force on the outer rubber sleeve 5 (such as During a tug-of-war game, the referee steps on the rope, and after the game starts, the players on both sides straighten the rope and lift the referee up), thereby preventing the armor skin 2 from being squeezed, and due to the presence of the shear thickening fluid in the cavity, when the outer rubber sleeve 5 is squeezed, the outer rubber sleeve 5 squeezes the shear thickening fluid to move in other directions. At this time, the shear thickening fluid acts on the local squeezing of the outer rubber sleeve 5 to other parts of the adjacent cavity, thereby dispersing the local squeezing of the outer rubber sleeve 5, avoiding the local pressure of the armor skin 2 from being too large and deforming. When the impact force is too large, the outer rubber sleeve 5 will be squeezed. When the outer rubber sleeve 5 and the inner rubber sleeve 3 are damaged, the residual impact force acts on the armor skin 2. The armor skin 2 is deformed after the impact. When the armor skin 2 is deformed, in addition to the impacted part, the vicinity of the impacted part is also deformed synchronously, thereby dispersing the impact force of the armor skin 2 on the buffer sleeve 103. The armor skin 2 is deformed to squeeze the buffer sleeve 103 inside it to deform. The buffer sleeve 103 cushions the impact on the armor skin 2 to prevent the deformation of the armor skin 2 from acting on the butterfly sheath 101 and causing damage to the optical fiber 1.

[0023] Existing optical cable ducts generally lay multiple optical cables, which are placed in a disorderly manner in the duct. When the optical cable is damaged and repaired, the multiple optical cables are entangled with each other, resulting in great resistance in the process of taking out the optical cable, which affects work efficiency. In addition, when laying a new optical cable in the duct, it is necessary to first extend a traction rope from one end of the duct to the other end, then connect the traction rope to the new optical cable, and then pull the traction rope to pull the optical cable into the duct to complete the laying. The process is complicated.

[0024] Embodiment 2: Based on Embodiment 1, an installation pipeline is provided, wherein the installation pipeline uses the above-mentioned butterfly optical cable with an impact-resistant structure, such as Figure 1 , Figure 2 , Figure 5-Figure 8As shown, a pipeline 6 is included, and the pipeline 6 is used to lay butterfly optical cables. The pipeline 6 is rotatably connected to two rotating shafts 7 which are symmetrically distributed front and back and pass through the pipeline 6. The rotating shaft 7 is rotatably connected to three sprocket wheels 8 which are evenly distributed along its axis. A chain 9 is arranged between two corresponding sprocket wheels 8 on different rotating shafts 7. The chain 9 is fixedly connected to an articulated seat 10 which is symmetrical and evenly distributed left and right. The articulated seat 10 is rotatably connected to a clamp 11, and the clamp 11 is used to clamp the optical cable. The chain 9 rotates to drive the clamp 11 to drive the optical cable to move. The clamp 11 is elastic and is used to clamp optical cables of different sizes. When the diameter of the optical cable is large, the two adjacent clamps 11 are deformed when clamping the optical cable, and the optical cable is clamped. A torsion spring is arranged between the clamp 11 and the adjacent articulated seat 10, and the torsion spring is used to reset the adjacent clamp 11.

[0025] like Figure 2 and Figure 5-Figure 8 As shown, four evenly distributed fixing frames 12 are fixed in the pipe 6, and three evenly distributed extrusion plates 13 are fixed on the upper sides of the four fixing frames 12. The front and rear sides of the extrusion plates 13 are provided with symmetrically distributed inclined surfaces for allowing adjacent clamps 11 to rotate around their rotating connections with adjacent hinge seats 10.

[0026] like Figure 7 and Figure 8 As shown, a roller 14 is rotatably connected to one side of the clamp 11 close to the extrusion plate 13, and the roller 14 is in contact with the adjacent extrusion plate 13. The roller 14 is used to reduce the friction between the clamp 11 and the adjacent extrusion plate 13, thereby reducing the resistance when laying the optical cable and extending the service life of the optical cable.

[0027] like Figure 6 and Fig. 9 As shown, the rotating shaft 7 on the front side is spline-connected with three evenly distributed sliding blocks 15, and six circumferentially evenly distributed bosses 16 are fixed to the right side of the sliding block 15. Six circumferentially evenly distributed grooves are arranged on the left side of the sprocket 8. The bosses 16 are limitedly matched with adjacent grooves. When the bosses 16 are inserted into adjacent grooves on adjacent sliding blocks 15, the sliding blocks 15 rotate with the adjacent rotating shafts 7, and the adjacent sprockets 8 are driven to rotate through the adjacent bosses 16. An inclined surface is arranged on the right side of the bosses 16 to make it easier for the bosses 16 to be inserted into adjacent grooves.

[0028] When laying the optical cable, first bury the pipeline 6 at the place of use, then put the outer rubber sleeve 5 on the upper side of one of the chains 9, then push the adjacent sliding block 15 to move to the right, so that the six bosses 16 on the sliding block 15 are inserted into the grooves of the adjacent sprocket 8, and then rotate the rotating shaft 7 clockwise from the right side view, the rotating shaft 7 drives the three sliding blocks 15 to rotate, the sliding block 15 drives the adjacent sprocket 8 to rotate through the bosses 16 thereon, the sprocket 8 drives the adjacent chain 9 to rotate clockwise from the right side view, the chain 9 drives the hinge seat 10 thereon to rotate, the hinge seat 10 drives the adjacent clamp 11 to rotate, after the clamp 11 rotates from the lower side of the adjacent chain 9 to the upper side, the clamp 11 drives the roller 14 thereon to move backward until it contacts the inclined surface of the adjacent extrusion plate 13, at this time the extrusion plate 13 squeezes the roller 14, the roller 14 moves backward while rolling along the edge of the adjacent extrusion plate 13, and the roller 14 drives the adjacent The adjacent clamps 11 rotate around the rotation connection between them and the adjacent hinged seats 10 and store force on the adjacent torsion springs. When the roller 14 moves to separate from the inclined surface on the front side of the extrusion plate 13, the two adjacent clamps 11 clamp the outer rubber sleeve 5 and drive it to move backward. As the chain 9 rotates, the two subsequent adjacent clamps 11 clamp the outer rubber sleeve 5 again. When the outer rubber sleeve 5 passes through the rear side of the pipe 6, the two clamps 11 that originally clamped the outer rubber sleeve 5 contact the inclined surface on the rear side of the adjacent extrusion plate 13. At this time, the clamps 11 rotate under the action of the adjacent torsion springs, so that the adjacent rollers 14 keep in contact with the inclined surface on the rear side of the adjacent extrusion plate 13. When the roller 14 separates from the inclined surface on the rear side of the adjacent extrusion plate 13, the clamps 11 reset under the action of the adjacent torsion springs and release the clamping of the outer rubber sleeve 5. When the length of the outer rubber sleeve 5 is adjusted appropriately, the rotation of the rotating shaft 7 is stopped. At this time, the laying of the outer rubber sleeve 5 in the pipe 6 is completed.

[0029] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
