Description

Technical Field

[0001] This utility model relates to the field of fiber optic slip ring installation technology, specifically a portable multi-channel fiber optic rotating device. Background Technology

[0002] A fiber optic slip ring is a device that can rotate 360 ​​degrees without restriction when transmitting optical signals. Its main function is to prevent signal interruption when transmitting fiber optic signals.

[0003] Unlike electrical cables, optical fibers face significant challenges in harsh environments like ports and docks. Splicing broken fibers using fusion splicing poses a risk of further breakage, necessitating redundant fiber optic cables at one end for easier maintenance. However, these redundant cables lack a fixed position after coiling, especially at the rotor end where they need to rotate with the rotor, making installation difficult. Conventional fiber optic slip rings typically use a two-end cable drop configuration, which cannot meet the direct fiber optic coupler output requirements of port and dock environments. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a portable, multi-channel fiber optic rotating device. This device solves the problem that when installing transmission optical cables with fiber optic slip rings in port and dock scenarios, redundant optical cables lack fixed positions, making installation difficult and inconvenient to match the direct fiber optic coupler output required in port and dock scenarios.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A portable multi-channel fiber optic rotating device includes a fiber optic slip ring. A rotor end frame panel is fixedly connected to the rotor shell of the fiber optic slip ring. Several fiber optic coupler fixing plates are fixedly connected between the rotor end frame panels. Several mounting holes are equally spaced on the fiber optic coupler fixing plates, and fiber optic connector females are fixedly installed in the mounting holes.

[0009] Preferably, an installation belt is fixedly connected to the stator housing of the fiber optic slip ring, an intermediate connecting base is rotatably connected to one side of the rotor end frame panel, a stator end frame panel is fixedly connected to the side of the intermediate connecting base away from the rotor end frame panel, one stator end frame panel away from the intermediate connecting base is fixedly connected to the installation belt, and several fiber optic coupler fixing plates are fixedly connected between the stator end frame panels.

[0010] Preferably, the outermost panel of the rotor end frame panel is fixed to the whole machine by fixing bolts.

[0011] Preferably, the mounting belt is a flexible belt.

[0012] Preferably, the mounting belt is provided with a number of reserved holes.

[0013] (III) Beneficial Effects

[0014] This utility model has the following beneficial effects:

[0015] (1) The portable multi-channel optical fiber rotating device, by adopting a frame structure, can meet the need for winding redundant optical cables. In some environments with sufficient space, the stator end redundant optical cables can be wound and placed on the ground. Only simple protection is needed to meet the need for the rotor end to wind and fix the optical cables, so that the wound optical cables can rotate together with the rotor end, thus solving the risk of the optical cables being easily broken due to the messy external coils.

[0016] (2) Compared with the conventional optical fiber slip ring stator end metal part reserved gap matching method, the portable multi-channel optical fiber rotating device requires installation to ensure concentricity and avoid the gap being too small to prevent seizing. The installation belt fixing method can solve the problem of installation concentricity requirement. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1 This utility model provides a technical solution: a portable multi-channel optical fiber rotating device, including an optical fiber slip ring 3, a rotor end frame panel 6 fixedly connected to the rotor shell of the optical fiber slip ring 3, a plurality of optical fiber coupler fixing plates 4 fixedly connected between the rotor end frame panels 6, a plurality of mounting holes 7 equally spaced on the optical fiber coupler fixing plates 4, and an optical fiber connector female head 5 fixedly installed in the mounting holes 7.

[0025] This utility model, by adopting a frame structure, can meet the need for coiling redundant optical cables. In some environments with sufficient space, the redundant optical cables at the stator end can be coiled and placed on the ground with only simple protection. This can meet the need for the rotor end to coil and fix the optical cables, so that the coiled optical cables can rotate together with the rotor end, thus solving the risk of the optical cables being easily twisted and broken when the coils are messy on the outside.

[0026] Example 2

[0027] Reference Figure 2 and 3 As shown, in this embodiment, an installation belt 2 is fixedly connected to the stator shell of the fiber optic slip ring 3. An intermediate connecting base 8 is rotatably connected to one side of the rotor end frame panel 6. A stator end frame panel 1 is fixedly connected to the side of the intermediate connecting base 8 away from the rotor end frame panel 6. A stator end frame panel 1 away from the intermediate connecting base 8 is fixedly connected to the installation belt 2. Several fiber optic coupler fixing plates are fixedly connected between the stator end frame panels. By extending the frame structure at the stator end of the fiber optic slip ring 3, the need for winding redundant optical cables can be met. The cable can be wound and then fixed as a whole on the frame, rotating with the rotor end and remaining fixed with the stator end, thus solving the risk of the optical cable being easily broken due to external mess. Conventional fiber optic slip ring 3 uses a metal part with a pre-reserved gap fit at the stator end, requiring concentricity during installation to avoid excessive gap and seizing. The installation belt 2 fixing method solves the problem of concentricity requirements.

[0028] In this embodiment, the outermost panel of the rotor end frame panel 6 is fixed to the whole machine by fixing bolts 9.

[0029] Reference Figure 2 and 3As shown, in this embodiment, the mounting belt 2 is a flexible belt. By using a flexible mounting belt 2, the belt absorbs the mechanical impact generated by the stator end during rotation or vibration through elastic deformation, avoiding stress concentration caused by rigid connection, thereby protecting the precision alignment structure of the fiber optic collimator. The flexible belt can adapt to small installation deviations (such as axial offset or angular tilt), ensuring the stability of optical signal transmission. Non-contact fixing reduces the rotational resistance of the stator end, extends the slip ring life, and avoids the influence of electromagnetic interference on the signal. Conventional fiber optic slip rings 3 use a metal part with a reserved gap fit at the stator end, requiring concentricity during installation to avoid excessive gap and seizing. The flexible belt fixing method can solve the problem of installation concentricity requirements.

[0030] Reference Figure 2 and 3 As shown in this embodiment, the mounting belt 2 has several pre-drilled holes. By arranging pre-drilled holes on the mounting belt 2, it is possible to quickly install and fix the mounting belt 2, thereby improving installation efficiency.
