[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In one embodiment of the present invention, an underwater photoelectric distributor is provided, wherein the inlet end cap and the outlet end cap of the underwater photoelectric distributor are respectively connected to the two ends of the cylinder, the inlet oil filling assembly and the multiple outlet oil filling assemblies are respectively connected to the two sides of the inlet end cap and the outlet end cap, and the wiring harness in the inlet oil filling assembly can be connected to the wiring harness of the multiple outlet oil filling assemblies in the cylinder to realize the wiring harness distribution. Figure 1 and Figure 2 The figure further describes the underwater optoelectronic distributor in this embodiment.

[0025] like Figure 1 As shown, the underwater photoelectric distributor in this embodiment includes: a cylinder 1, an inlet end cover 2, an outlet end cover 3, an inlet oil filling component 4 and a plurality of outlet oil filling components 5.

[0026] Among them, the cylinder 1 is roughly constructed as a hollow cylindrical structure, with openings provided at both ends of the cylinder 1, the inlet end cover 2 and the outlet end cover 3 are respectively connected to the openings at both ends of the cylinder 1 and can close the openings, the inlet oil filling assembly 4 is connected to the inlet end cover 2 and communicated with the internal space of the cylinder 1, and multiple outlet oil filling assemblies 5 are connected to the outlet end cover 3 and communicated with the internal space of the cylinder 1.

[0027] It can be understood that the cylinder body 1 in this embodiment can be constructed as a cylindrical structure with a certain length and openings at both ends, and the cylinder body 1 can be constructed of corrosion-resistant metal materials or non-metallic materials.

[0028] The inlet end cover 2 and the outlet end cover 3 are both constructed as circular plate structures with a certain thickness. The inlet end cover 2 and the outlet end cover 3 can be connected to the openings at both ends of the cylinder 1 respectively by means of bolt structures. The inlet end cover 2 and the outlet end cover 3 can also close the openings at both ends of the cylinder 1, thereby forming the internal space of the cylinder 1 into a closed space.

[0029] The inlet oil filling assembly 4 is connected to the inlet end cover 2 , and the inlet oil filling assembly 4 is connected to the inner space of the cylinder 1 . The wiring harness in the main cable can extend into the inner space of the cylinder 1 through the inlet oil filling assembly 4 .

[0030] As an implementation method, the inlet end cover 2 is provided with an inlet connection channel penetrating along the thickness direction thereof, the tubular structure in the inlet oil filling assembly 4 is sealed and connected to the inlet connection channel, and the hollow tube cavity of the tubular structure is connected to the internal space of the cylinder 1. Therefore, when the main cable is connected to the inlet oil filling assembly 4, the wiring harness in the main cable can extend into the internal space of the cylinder 1 through the inlet oil filling assembly 4.

[0031] Similarly, a plurality of outlet oil filling assemblies 5 are connected to the outlet end cover 3 , and the outlet oil filling assemblies 5 are connected to the inner space of the cylinder 1 , and the wiring harnesses in the plurality of branch cables can extend into the inner space of the cylinder 1 through the outlet oil filling assemblies 5 .

[0032] As an implementation method, the outlet end cover 3 is provided with an outlet connection channel penetrating along the thickness direction thereof, and the tubular structures in the multiple outlet oil filling components 5 are sealed and connected to the outlet connection channel, and the hollow tube cavity of the tubular structure is connected to the internal space of the cylinder 1. Therefore, when multiple branch cables are connected to the outlet oil filling components 5 one by one, the wiring harnesses in the multiple branch cables can all extend into the internal space of the cylinder 1 through the outlet oil filling components 5.

[0033] In actual use, when it is necessary to distribute and connect a main cable to multiple branch cables underwater, the main cable can be connected to the inlet oil-filling assembly 4, and the wiring harness in the main cable can be extended to the internal space of the cylinder 1. At the same time, multiple branch cables can be connected to the outlet oil-filling assembly 5 one by one, and the wiring harnesses in the multiple branch cables can be extended to the internal space of the cylinder 1. Afterwards, the wiring harness in the main cable is connected to the wiring harnesses in different branch cables in the internal space of the cylinder 1 respectively, thereby realizing the redistribution of cables at the nodes.

[0034] The underwater photoelectric distributor in this embodiment has a simple structure, is easy to assemble, and has good sealing performance, and can effectively meet the underwater working environment.

[0035] Furthermore, in order to effectively fix the inlet cover 2 and the outlet cover 3, as Figure 1 As shown, in this embodiment, the underwater optoelectronic distributor further includes a support shaft 6, which is disposed in the inner space of the cylinder 1, and both ends of the support shaft 6 are respectively connected to the inlet end cover 2 and the outlet end cover 3.

[0036] It can be understood that the wire harness in the main cable and the wire harness in the multiple branch cables need to be fixedly connected in advance. In order to facilitate the connection of these wire harnesses, the main cable and the multiple branch cables can be connected to the inlet end cover 2 and the outlet end cover 3 respectively, and then the inlet end cover 2 and the outlet end cover 3 are fixedly connected by the support shaft 6. After that, the wire harness connection can be conveniently realized. When the wire harness connection is completed, the barrel 1 can be directly sleeved on the support shaft 6, and the inlet end cover 2 and the outlet end cover 3 are respectively connected and close the openings at both ends of the barrel.

[0037] Optionally, in one embodiment, the support shaft 6 extends along the axial direction of the cylinder 1 , and the support shaft 6 is located at the axial center of the cylinder 1 .

[0038] In actual use, the wiring harness in the main cable and the wiring harness in multiple branch cables need to be connected in the internal space of the cylinder 1 with the help of quick connectors. In order to avoid redundancy, interference and entanglement of these quick connectors in the internal space of the cylinder 1, thereby causing safety hazards, in this embodiment, the underwater optoelectronic distributor also includes a quick connector bracket 7, which is located in the internal space of the cylinder 1 and is fixedly set on the support shaft 6.

[0039] In this embodiment, after the wiring harness in the main cable and the wiring harness in the plurality of branch cables are connected one by one by means of quick connectors, these quick connectors can be fixedly mounted on the quick connector bracket 7. For example, these quick connectors can be fixed on the quick connector bracket 7 by means of a bolt structure or a snap-on structure.

[0040] In one embodiment, the quick connector bracket 7 may be extended along the radial direction of the support shaft 6, and the number of the quick connector bracket 7 may be multiple, and the multiple quick connector brackets 7 may be sequentially spaced along the circumferential direction of the support shaft 6. For example, in this embodiment, two quick connector brackets 7 are provided, and the two quick connector brackets 7 are symmetrically arranged and extend outward along the radial direction of the support shaft 6.

[0041] The main cable and the branch cable can be oil-filled cables, and for this purpose, the internal space of the cylinder 1 needs to be filled with oil.

[0042] In order to conveniently fill the inner space of the cylinder 1 with oil, in this embodiment, Figure 2 As shown, the inlet end cover 2 is provided with an oil filling hole 8 and an exhaust hole 9.

[0043] In actual use, after the inlet end cover 2 and the outlet end cover 3 are respectively sealed and connected to the openings at both ends of the cylinder 1, the entire underwater photoelectric distributor can be extended and placed in the vertical direction with the inlet end cover 2 facing upward. Then, the oil filling hole 8 and the exhaust hole 9 are opened, and the oil filling hole 8 is used to fill oil into the internal space of the cylinder 1. When filled with oil, the oil filling hole 8 and the exhaust hole 9 are sealed using sealing parts such as screws.

[0044] In this embodiment, in the axial direction of the cylinder 1 , the inlet end cover 2 is embedded in the opening at one end of the cylinder 1 , and the circumferential outer surface of the inlet end cover 2 and the circumferential inner surface of the cylinder 1 abut against each other.

[0045] Furthermore, in order to improve the sealing effect between the inlet end cover 2 and the cylinder 1, prevent foreign matter such as water in the external environment from entering the internal space of the cylinder 1, and prevent the oil in the internal space of the cylinder 1 from leaking to the outside, in the present embodiment, the circumferential outer surface of the inlet end cover 2 is provided with an annular first sealing ring groove, and a first sealing ring 10 is provided in the first sealing ring groove. The first sealing ring 10 can form a seal between the circumferential outer surface of the inlet end cover 2 and the circumferential inner surface of the cylinder 1.

[0046] That is to say, when the inlet end cover 2 is installed in the opening at one end of the cylinder 1, the first sealing ring 10 can abut against the inlet end cover 2 and the cylinder 1 simultaneously along the circumferential direction, thereby achieving sealing.

[0047] Exemplarily, the first sealing ring 10 may be a rubber sealing ring.

[0048] In this embodiment, the inlet end cover 2 can be completely embedded in the opening at one end of the cylinder 1, so that the cylinder 1 can be easily mounted on the inlet end cover 2, the support shaft 6 and the outlet end cover 3.

[0049] Preferably, the outer end surface of the inlet end cover 2 can be flush with the end surface of one end of the cylinder 1.

[0050] In addition, in order to achieve a fixed connection between the inlet end cover 2 and the cylinder 1, as an implementation method, one end of the cylinder 1 is provided with a plurality of through holes penetrating along its radial direction, and the plurality of through holes can be evenly spaced along the circumferential direction of the cylinder 1, and the inlet end cover 2 is provided with threaded holes corresponding to the plurality of through holes. In the actual installation process, external screws can pass through the plurality of through holes at one end of the cylinder 1 and connect with the threaded holes of the inlet end cover 2. In this way, a fixed connection between the inlet end cover 2 and the cylinder 1 can be achieved.

[0051] It can be understood that the threaded hole on the inlet end cover 2 should be arranged outside the first sealing ring groove to prevent the internal space of the cylinder 1 from being connected to the external environment through the through hole on the cylinder 1.

[0052] In this embodiment, the outlet end cover 3 includes a connecting portion 31 and a flange portion 32. In the axial direction of the cylinder 1, the connecting portion 31 is embedded in the opening at the other end of the cylinder 1, the circumferential outer surface of the connecting portion 31 and the circumferential inner surface of the cylinder 1 abut against each other, the flange portion 32 is connected to the outer side of the connecting portion 31, the flange portion 32 extends outward along the radial direction of the outlet end cover 3, and the flange portion 32 abuts against the end surface of the other end of the cylinder 1.

[0053] It is understood that the outlet cover 3 can be constructed as a circular plate-like structure with an annular flange structure. During actual assembly, the connection portion 31 of the outlet cover 3 can be completely embedded in the opening at the other end of the cylinder 1, and at the same time, in the axial direction of the cylinder 1, the annular flange portion 32 can abut against the end surface of the other end of the cylinder 1.

[0054] Similar to the above, in order to improve the sealing effect between the outlet end cover 3 and the cylinder 1, prevent foreign matter such as water in the external environment from entering the internal space of the cylinder 1, and prevent the oil in the internal space of the cylinder 1 from leaking to the outside, in the present embodiment, the circumferential outer surface of the connecting part 31 is provided with an annular second sealing ring groove, and a second sealing ring 11 is provided in the second sealing ring groove. The second sealing ring 11 can form a seal between the circumferential outer surface of the connecting part 31 and the circumferential inner surface of the cylinder 1.

[0055] That is to say, when the outlet end cover 3 is installed in the opening at the other end of the cylinder 1, the second sealing ring 11 can abut against the outlet end cover 3 and the cylinder 1 simultaneously along the circumferential direction, thereby achieving sealing.

[0056] Exemplarily, the second sealing ring 11 may also be a rubber sealing ring.

[0057] Accordingly, in order to achieve a fixed connection between the outlet end cover 3 and the cylinder 1, as a way of implementation, the end surface of the other end of the cylinder 1 is provided with a plurality of threaded holes arranged at intervals along its circumferential direction, and the flange portion 32 of the outlet end cover 3 is provided with through holes corresponding to the plurality of threaded holes. In the actual installation process, external screws can pass through the plurality of through holes of the flange portion 32 and connect with the threaded holes of the cylinder 1. In this way, a fixed connection between the outlet end cover 3 and the cylinder 1 can be achieved.

[0058] In addition, the underwater optoelectronic distributor in this embodiment further includes a clamp 12 . The clamp 12 is sleeved on the outside of the cylinder 1 , and the cylinder 1 is connected to an external device via the clamp 12 .

[0059] For example, the number of the clamps 12 may be two, and the two clamps 12 are spaced apart in the axial direction of the cylinder 1 .

[0060] The underwater photoelectric distributor in this embodiment can be assembled in the following manner:

[0061] First, install the inlet oil filling assembly 4 to the inlet end cover 2, and install the outlet oil filling assembly 5 to the outlet end cover 3;

[0062] Next, the inlet cover 2 and the outlet cover 3 are respectively installed on both ends of the support shaft 6, for example, they can be fixed by bolts or other structures;

[0063] Then, the wire harness in the main cable extending from the inlet oil filling assembly 4 is connected to the wire harness in the branch cables extending from the multiple outlet oil filling assemblies 5 one by one by using a quick connector, and the quick connector is fixed on the quick connector bracket 7;

[0064] Afterwards, the above-mentioned preliminarily assembled parts are slowly pushed into the cylinder body along the axial direction of the cylinder body 1. For example, the inlet end cover 2, the support shaft 6 and the outlet end cover 3 can be pushed into the cylinder body 1 in sequence. When the flange portion 32 of the outlet end cover 3 abuts against the end surface of the other end of the cylinder body 1, it means that the installation is in place. At this time, the through hole on the cylinder body 1 can be aligned with the threaded hole of the inlet end cover 2, and the through hole on the flange portion 32 can be aligned with the threaded hole at one end of the cylinder body 1, and fastened with standard parts such as bolts and set screws;

[0065] Then, the underwater photoelectric distributor is placed in a vertical direction with the inlet end cover 2 facing upward, and oil is filled into the inner space of the cylinder 1 from the oil filling hole 8. After the oil is filled, the oil filling hole 8 and the exhaust hole 9 are sealed with sealing parts such as sealing screws;

[0066] Finally, a clamp 12 is fastened to the outside of the cylinder 1, and the underwater optoelectronic distributor is fixed to external equipment as required.

[0067] Therefore, the underwater photoelectric distributor in this embodiment has the following advantages:

[0068] The underwater photoelectric distributor in this embodiment includes: a cylinder, an inlet end cover, an outlet end cover, an inlet oil-filling assembly, and a plurality of outlet oil-filling assemblies. The inlet end cover and the outlet end cover are respectively connected to the two ends of the cylinder, the inlet oil-filling assembly and the plurality of outlet oil-filling assemblies are respectively connected to the two sides of the inlet end cover and the outlet end cover, and the wiring harness in the inlet oil-filling assembly can be connected to the wiring harness of the plurality of outlet oil-filling assemblies in the cylinder to achieve the distribution of the wiring harness. The wiring harness is connected in the confined space of the cylinder, which can ensure the sealing effect and can adapt to the underwater working environment.

[0069] Moreover, the underwater optoelectronic distributor can reduce the processing difficulty and cost through the split assembly method. At the same time, during assembly and installation, the end covers on both sides can be pre-installed through the support shaft, and the wiring harness inside the cable can be connected through a quick connector, and then the whole is installed into the cylinder, so that the redundancy of the wiring harness is more controllable, the installation is more convenient, the safety of the wiring harness installation can be improved, and the structure is beautiful.
