Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber laying, and particularly relates to an optical fiber multi-point air-blowing pipe and an optical fiber multi-point air-blowing joint. Background Art

[0002] With the rapid development of network technology, the demand for optical fiber laying across the country has been increasing year by year. The optical fiber 3 is laid underground, and generally an optical fiber inspection well 2 is set every 100 m. Two adjacent optical fiber inspection wells are connected by a buried pipe 1.

[0003] When laying the optical fiber, as Figure 1 shown, a spherical ball 4 is fixed at the end of the optical fiber 3. First, the optical fiber 3 is inserted into the buried pipe 1, and the high-pressure air formed by the air-blowing device blows the spherical ball 4 at one end of the buried pipe 1, so that the spherical ball 4 passes through the buried pipe 1 until the second optical fiber inspection well 2; at this time, the spherical ball 4 is exposed, and this section of pipeline laying is completed. Then, the spherical ball 4 is manually sent into the second optical fiber inspection well 2, and the high-pressure air formed by the air-blowing device blows the spherical ball 4 at the optical fiber inspection well 2, so that the spherical ball 4 passes through the buried pipe until the third optical fiber inspection well. And so on until the long-distance laying of the optical fiber is completed.

[0004] In the above laying process, after the high-pressure air generated by the air-blowing device blows the spherical ball out of the buried pipe, the air pressure drops and continuous blowing cannot be performed, resulting in a reduction in work efficiency.

[0005] In view of this, based on the production design experience in this field and related fields for many years, the inventor of the present invention has designed an optical fiber multi-point air-blowing pipe and an optical fiber multi-point air-blowing joint through repeated tests, in order to solve the problems existing in the prior art. Summary of the Invention

[0006] The purpose of the present invention is to provide an optical fiber multi-point air-blowing pipe and an optical fiber multi-point air-blowing joint, which can supplement the pressure of the high-pressure air in the pipe during ultra-long-distance laying of the optical fiber.

[0007] To achieve the above purpose, the present invention provides an optical fiber multi-point air-blowing pipe, wherein the optical fiber multi-point air-blowing pipe includes a plurality of buried pipe bodies and a plurality of optical fiber multi-point air-blowing joints. Each of the buried pipe bodies has a first optical fiber laying channel axially penetrating therethrough, and each of the optical fiber multi-point air-blowing joints has a second optical fiber laying channel axially penetrating therethrough. The plurality of buried pipe bodies are sequentially arranged at intervals, and one of the optical fiber multi-point air-blowing joints is provided between every two adjacent buried pipe bodies. Both ends of each of the optical fiber multi-point air-blowing joints are detachably and sealingly connected to the ends of the corresponding buried pipe bodies, and a blowing through hole capable of blowing air into the second optical fiber laying channel is formed in the side wall of each of the optical fiber multi-point air-blowing joints.

[0008] The present invention also provides a fiber optic multi-point air blowing joint. The fiber optic multi-point air blowing joint is used to connect two buried pipe bodies. The fiber optic multi-point air blowing joint is cylindrical and has a second fiber optic laying channel that penetrates axially. Both ends of the fiber optic multi-point air blowing joint can be detachably and sealingly connected to the corresponding buried pipe bodies respectively. A blowing through hole that can blow air into the second fiber optic laying channel is provided on the side wall of the fiber optic multi-point air blowing joint.

[0009] For the fiber optic multi-point air blowing joint as described above, the axis of the blowing through hole is inclined with respect to the second fiber optic laying channel.

[0010] For the fiber optic multi-point air blowing joint as described above, the inner diameter of the blowing through hole is the same as the inner diameter of the second fiber optic laying channel.

[0011] For the fiber optic multi-point air blowing joint as described above, the fiber optic multi-point air blowing joint includes a lower seat and an upper cover. The lower seat has a through groove in a semi-circular arc shape. The upper cover is in a semi-cylindrical shape. The upper cover is buckled on the lower seat, and the inner wall of the upper cover and the inner wall of the through groove enclose to form the second fiber optic laying channel.

[0012] For the fiber optic multi-point air blowing joint as described above, both ends of the lower seat protrude from the upper cover to form connection ends. The fiber optic multi-point air blowing joint further includes two semi-cylindrical tile covers. The two tile covers are respectively arranged on the two connection ends, and each tile cover and its corresponding connection end are detachably connected through a locking mechanism.

[0013] For the fiber optic multi-point air blowing joint as described above, the locking mechanism includes a locking bolt and a limiting block. The limiting block is arranged on the outer wall of the tile cover and is in alignment and cooperation with the connection end. The locking bolt penetrates through the limiting block and is threadedly connected to the connection end.

[0014] For the fiber optic multi-point air blowing joint as described above, two locking mechanisms are provided between the connection end and the tile cover, and the two locking mechanisms are symmetrically arranged on both sides of the through groove.

[0015] For the fiber optic multi-point air blowing joint as described above, the lower seat and the upper cover, and the upper cover and the tile cover are respectively connected through a rabbet structure.

[0016] For the fiber optic multi-point air blowing joint as described above, the inner wall of the blowing through hole protrudes from the outer side wall of the upper cover to form a connection head.

[0017] Compared with the prior art, the present invention has the following features and advantages:

[0018] The fiber optic multi-point air-blowing pipe and the fiber optic multi-point air-blowing joint proposed by the present invention, at each fiber optic inspection well, the two buried underground buried pipe bodies are hermetically connected together through the fiber optic multi-point air-blowing joint, thus forming a fiber optic multi-point air-blowing pipe that connects multiple fiber optic inspection wells in series. When laying the optical fiber, a spherical ball is fixed at the end of the optical fiber, and the spherical ball is passed through one end of the fiber optic multi-point air-blowing pipe. The high-pressure air formed by the air-blowing equipment in the fiber optic multi-point air-blowing pipe will drive the spherical ball at the end of the optical fiber to move, and then drive the optical fiber to continuously pass through multiple fiber optic inspection wells. At the same time, high-pressure air pressure is supplemented to the second optical fiber laying channel through the air-blowing through holes, which can effectively increase the moving distance of the spherical ball, complete the ultra-long-distance and high-efficiency laying of the optical fiber, and improve the optical fiber laying efficiency.

[0040] Combined with the description of the specific embodiments of the present invention and the accompanying drawings, the details of the present invention can be more clearly understood. However, the specific embodiments of the present invention described herein are only for the purpose of explaining the present invention and cannot be construed in any way as a limitation of the present invention. Under the teaching of the present invention, those skilled in the art can conceive any possible variations based on the present invention, and these should all be regarded as belonging to the scope of the present invention.

[0041] As Figures 2 to 7 shown, the present invention provides an optical fiber multi-point air blowing drain pipe 100, which includes a plurality of buried drain pipe bodies 10 and a plurality of optical fiber multi-point air blowing connectors 20. Each buried drain pipe body 10 has an axially penetrating first optical fiber laying channel 11, and each optical fiber multi-point air blowing connector 20 has an axially penetrating second optical fiber laying channel 21. The plurality of buried drain pipe bodies 10 are arranged sequentially at intervals, and an optical fiber multi-point air blowing connector 20 is provided between every two adjacent buried drain pipe bodies 10. The two ends of each optical fiber multi-point air blowing connector 20 are detachably and sealingly connected to the ends of the corresponding buried drain pipe body 10, and a blowing through hole 22 capable of blowing air into the second optical fiber laying channel 21 is provided on the side wall of each optical fiber multi-point air blowing connector 20.

[0042] An optical fiber multi-point air-blowing joint 20 proposed by the present invention is used to connect two buried pipe bodies 10. The optical fiber multi-point air-blowing joint 20 is cylindrical and has a second optical fiber laying channel 21 that penetrates axially. Both ends of the optical fiber multi-point air-blowing joint 20 can be detachably and sealingly connected to the corresponding buried pipe bodies 10. An air-blowing through hole 22 capable of blowing air into the second optical fiber laying channel 21 is provided on the side wall of the optical fiber multi-point air-blowing joint 20.

[0043] For the optical fiber multi-point air-blowing pipe 100 and the optical fiber multi-point air-blowing joint 20 proposed by the present invention, at each optical fiber inspection well 300, the two buried pipe bodies 10 buried underground are sealingly connected together through the optical fiber multi-point air-blowing joint 20, thereby forming an optical fiber multi-point air-blowing pipe 100 that connects multiple optical fiber inspection wells 300 in series. When laying the optical fiber 200, a sphere 201 is fixed at the end of the optical fiber 200, and the sphere 201 is passed through one end of the optical fiber multi-point air-blowing pipe 100. The high-pressure air formed by the air-blowing device in the optical fiber multi-point air-blowing pipe 100 will drive the sphere 201 at the end of the optical fiber 200 to move, and then drive the optical fiber 200 to continuously pass through multiple optical fiber inspection wells 300. At the same time, high-pressure air pressure is supplemented into the second optical fiber laying channel 21 through the air-blowing through hole 22, which can effectively increase the moving distance of the sphere 201, complete the ultra-long-distance and high-efficiency laying of the optical fiber, and improve the laying efficiency of the optical fiber 200.

[0044] In an alternative embodiment of the present invention, the axis of the air-blowing through hole 22 is inclined to the second optical fiber laying channel 21.

[0045] In an alternative embodiment of the present invention, the inner diameter of the air-blowing through hole 22 is the same as the inner diameter of the second optical fiber laying channel 21.

[0046] In an alternative embodiment of the present invention, the optical fiber multi-point air-blowing joint 20 includes a lower seat 23 and an upper cover 24. The lower seat 23 has a semi-circular arc-shaped through groove 231. The upper cover 24 is semi-cylindrical. The upper cover 24 is buckled on the lower seat 23, and the inner wall of the upper cover 24 and the inner wall of the through groove 231 enclose to form the second optical fiber laying channel 21. With the above structure, the optical fiber multi-point air-blowing joint 20 can be split along the diameter, and the lower seat 23 and the upper cover 24 can be opened or closed, which is convenient for the installation and disassembly of the optical fiber multi-point air-blowing joint 20; at the same time, it is also convenient for the repeated use of the optical fiber multi-point air-blowing joint 20.

[0047] In an alternative example of this embodiment, both ends of the lower seat 23 protrude from the upper cover 24 to form connecting ends 232. The optical fiber multi-point air blowing joint 20 further includes two semi-cylindrical tile covers 25, and the two tile covers 25 are respectively disposed on the two connecting ends 232. Each tile cover 25 and its corresponding connecting end 232 are detachably connected by a locking mechanism 26. With the above structure, the tile cover 25 and the connecting end 232 are clamped to the end of the buried pipe body 10 to achieve a detachable and sealed connection between the optical fiber multi-point air blowing joint 20 and the buried pipe body 10.

[0048] In an alternative example, the locking mechanism 26 includes a locking bolt 262 and a limiting block 261. The limiting block 261 is disposed on the outer wall of the tile cover 25 and is in alignment and cooperation with the connecting end 232. The locking bolt 262 passes through the limiting block 261 and is threadedly connected to the connecting end 232.

[0049] In an alternative example, two locking mechanisms 26 are provided between the connecting end 232 and the tile cover 25, and the two locking mechanisms 26 are symmetrically arranged.

[0050] In an alternative example, the lower seat 23 and the upper cover 24, and the upper cover 24 and the tile cover 25 are respectively connected by a rabbet structure 28.

[0051] In an alternative example, the inner wall of the air blowing through hole 22 protrudes from the outer side wall of the upper cover 24 to form a connection head 27, and the connection head 27 is used for external connection with an air blowing device to facilitate blowing air into the air blowing through hole 22.

[0052] In an alternative example, an outer cover capable of closing the air blowing through hole 22 is provided outside the connection head 27. When the air blowing through hole 22 is not in use, the air blowing through hole 22 is closed by the outer cover to prevent the high-pressure air flow in the second optical fiber laying channel from leaking.

[0053] The detailed explanations for the above embodiments are only for the purpose of explaining the present invention so that it can be better understood. However, these descriptions cannot be construed as limitations on the present invention for any reason. In particular, the various features described in different embodiments can be arbitrarily combined with each other to form other embodiments. Unless there are explicit and contrary descriptions, these features should be understood to be applicable to any one of the embodiments and not limited to the described embodiments only.
