Description

Technical Field

[0001] This utility model belongs to the field of railway cable protection technology, specifically relating to a fiber optic protective tube for railway use. Background Technology

[0002] Currently, most railway communication systems use ordinary spliced ​​pipes or PVC pipes as protective conduits for optical fibers. The gaps in spliced ​​pipes are on the outer wall, making them susceptible to rainwater intrusion when exposed to wind and rain. This can cause the optical fibers inside to become soaked, and prolonged soaking can damage them. While PVC pipes, as protective conduits for optical fibers, are not susceptible to rainwater intrusion, they have a shorter lifespan and will weather over time due to exposure to wind and sun. Furthermore, PVC pipes generally have thinner walls, making them more prone to damage under external forces. Both rainwater intrusion and damage to the protective conduit can lead to damage to the optical fibers inside, causing anomalies in railway communication. Utility Model Content

[0003] The purpose of this invention is to provide a protective tube for optical fiber used in railways, in order to solve at least one of the aforementioned problems in the prior art.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] This utility model provides a protective tube for optical fiber in railways, including an upper tube body, a lower tube body, a flat tube wall, a flange, and a connecting port. The upper tube body and the lower tube body are assembled and connected. The flat tube wall is located at the top of the upper tube body and the bottom of the lower tube body. The flange is located on both sides of the upper tube body and the lower tube body. The connecting port is located at both ends of the upper tube body and the lower tube body.

[0006] In a further technical solution, the upper tube flange wraps around the lower tube flange.

[0007] In a further technical solution, the connection port includes a socket and a spigot. The diameter of the socket is the same as the diameter of the pipe body, and the diameter of the spigot is larger than the diameter of the pipe body. The socket and spigot are in a receiving relationship.

[0008] In a further technical solution, the socket is provided with a protrusion, and the insertion port is provided with a groove.

[0009] In a further technical solution, fixing blocks are provided on both sides of the middle part of the socket and the tube body.

[0010] In a further technical solution, the fixing block is provided with a fixing groove.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] like Figures 1 to 10 As shown, this utility model embodiment provides a railway fiber optic protective tube, including an upper tube body 1, a lower tube body 2, a flat tube wall 3, a flange 4, and a connecting port 5. The upper tube body 1 and the lower tube body 2 are assembled and connected. The flat tube wall 3 is located at the top of the upper tube body 1 and the bottom of the lower tube body 2. The flange 4 is located on both sides of the upper tube body 1 and the lower tube body 2. The connecting port 5 is located at both ends of the upper tube body 1 and the lower tube body 2.

[0030] This utility model embodiment features a flat pipe wall 3 at the upper part of the upper pipe body 1 and the lower part of the lower pipe body 2, making it easy to install the pipe body onto the ground or wall and increasing the overall strength of the pipe body. A flange 4 is provided at the joint between the upper pipe body 1 and the lower pipe body 2 to prevent rainwater from seeping into the pipe body along the joint. Connection ports 5 are provided at both ends of the pipe body to facilitate the installation of adjacent pipe bodies. The overall structure is simple, easy to install, and the pipe body has high strength.

[0031] In one feasible implementation scheme, such as Figures 1 to 4 As shown, the upper pipe body 1 flange 4 wraps around the lower pipe body 2 flange 4. By setting the upper pipe body 1 flange 4 to wrap around the lower pipe body 2 flange 4, it is easy to distinguish between the upper and lower parts during installation, and it can also effectively prevent rainwater from seeping in from one side gap, greatly improving the waterproofness of the protective pipe.

[0032] In one feasible implementation scheme, such as Figures 5 to 6 As shown, the connection port 5 includes a socket 51 and a spigot 52. The diameter of the socket 51 is the same as the diameter of the pipe body, and the diameter of the spigot 52 is larger than the diameter of the pipe body. The socket 51 and the spigot 52 are in a receiving relationship. By setting one end of the protective pipe as a socket 51 and the other end as a spigot 52, and the diameter of the socket 51 is smaller than the diameter of the spigot 52, it is easier to insert and install two adjacent pipe sections, increasing convenience.

[0033] In one feasible implementation scheme, such as Figures 3 to 6 As shown, the socket 51 is provided with a protrusion 511, and the insertion port 52 is provided with a groove 521. By providing a protrusion 511 in the socket 51 and a groove 521 in the insertion port 52, after the socket 51 and the insertion port 52 are connected, the protrusion 511 will be stuck in the groove 521, thereby improving the stability of the connection between adjacent protective pipe sections.

[0034] In one feasible implementation scheme, such as Figures 2 to 10 As shown, fixing blocks 6 are provided on both sides of the socket 52 and the middle of the tube body. By providing fixing blocks 6 on both sides of the socket 52 and the middle of the tube body, the upper tube body 1 and the lower tube body 2 are fixed by fixing blocks 6 after assembly, so that the upper tube body 1 and the lower tube body 2 are tightly assembled together.

[0035] In one feasible implementation scheme, such as Figures 2 to 10 As shown, the fixing block 6 is provided with a fixing groove 61. By providing a fixing groove 61 on the fixing block 6, the fixing groove 61 can be used with bolts or screws to fasten the fixing block 6, preventing the assembled upper pipe 1 from separating from the lower pipe 2.

[0036] In one feasible implementation scheme, such as Figure 10 As shown, it also includes a 45-degree connecting pipe 7, which is an elbow. By setting the 45-degree connecting pipe 7, the protective pipe can bend, allowing it to be used in different environmental conditions and increasing the versatility of the protective pipe.

[0037] In the specific implementation of the railway fiber optic protective pipe provided in this utility model embodiment, the upper pipe body 1 and the lower pipe body 2 are assembled together and fastened with bolts or screws to the fixing groove 61 of the fixing block 6 on the protective pipe, so that the upper pipe body 1 and the lower pipe body 2 are tightly assembled together. The upper part of the upper pipe body 1 and the lower part of the lower pipe body 2 are provided with flat pipe walls 3. The flat pipe walls 3 are attached to the ground or wall surface. The setting of the flat pipe walls 3 also enhances the strength of the pipe body. When in use, it is fixed with pipe fixing rings. According to the required length, the socket 51 and the spigot 52 of two adjacent protective pipe sections can be connected together. The protrusion 511 of the socket 51 and the groove 521 of the spigot 52 will cooperate to firmly connect the two protective pipe sections. When encountering situations where a bend is required, a 45-degree connecting pipe 7 can be used as needed. The overall structure of the protective pipe is simple and easy to install.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
