Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication equipment technology, and more specifically, to a multi-channel wavelength division multiplexer. Background Technology

[0002] A wavelength division multiplexer (WDM) is a communication component that uses WDM technology to combine a series of optical signals carrying information but with different wavelengths into a single beam, transmit it along a single optical fiber, and then separate the different wavelengths of optical signals at the receiving end using some method. Its core components include multiplexers and demultiplexers. This technology is widely used in long-distance trunk lines, metropolitan area networks, and data center interconnections. WDM is compatible with existing optical fiber systems, effectively reducing expansion costs, while meeting the needs of high-speed and high-bandwidth communication, making outstanding contributions to the promotion of technologies such as 5G and cloud computing.

[0003] A search revealed a dense wavelength division multiplexer (WDM) with publication number CN208818861U. The background section addressed the issue that existing WDMs have complex and cumbersome structures, failing to meet market demands for miniaturized and dense optical communication devices. The section addressed this problem by incorporating a package, a first collimator, a filter, and a second collimator. However, the miniaturization of the device reduces the WDM's heat dissipation capacity. Therefore, manufacturers typically install heat sinks to improve the heat dissipation of smaller WDMs. However, due to dust in the environment, when a large amount of dust accumulates in the gaps between the heat sinks, the heat dissipation efficiency of the heat sinks decreases significantly, affecting the normal operation of the WDM. Therefore, improvements are needed. Utility Model Content

[0020] 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.

[0021] like Figures 1 to 5 As shown, this utility model provides a multi-channel wavelength division multiplexer, including an active multi-channel wavelength division multiplexer 1. Side plates 2 are fixedly connected to the outer surfaces of the front and rear sides of the active multi-channel wavelength division multiplexer 1. A motor 3 is fixedly installed on the front side of the upper surface of the side plates 2. A round shaft 4 is fixedly sleeved on the other end of the output shaft of the motor 3. An active rod 5 is fixedly sleeved on the outer surface of the round shaft 4. A driven rod 6 is hinged to the other end of the active rod 5. A movable plate 7 is movably sleeved on the other end of the driven rod 6. A cleaning brush 8 is movably connected to the lower surface of the movable plate 7. The active multi-channel wavelength division multiplexer 1 is internally equipped with components such as a wavelength division board, an optical amplification board, a dispersion compensation board, and an optical protection board, which can support more wavelength channels, thereby bringing greater bandwidth and higher fiber utilization. When the operator starts the motor 3, the round shaft 4, the active rod 5, and the driven rod 6 will start to rotate, and the other end of the driven rod 6 will drive the movable plate 7, thereby causing the movable plate 7 to move towards the active multi-channel wavelength division multiplexer 1.

[0022] Among them, a short rod 9 is fixedly connected to the upper surface of the cleaning brush 8. The top end of the short rod 9 passes through the moving plate 7 and extends to the top of the moving plate 7 and is fixedly connected to a long plate 10. A round block 11 is fixedly connected to the left side of the rear surface of the long plate 10. The design of the short rod 9 allows the cleaning brush 8 to move up and down only along the inner surface of the moving plate 7, while the design of the long plate 10 restricts the range of up and down movement of the cleaning brush 8.

[0023] The upper surface of the movable plate 7 is fixedly connected to the mounting bracket 12. The middle part of the upper surface of the mounting bracket 12 is fixedly installed with the second motor 13. The other end of the output shaft of the second motor 13 is fixedly sleeved with the rotating shaft 14. The outer surface of the rotating shaft 14 is fixedly sleeved with the driving rod 15. The inner surface of the driving rod 15 is movably connected to the outer surface of the round block 11. When the operator starts the second motor 13, the rotating shaft 14 and the driving rod 15 will start to rotate. At this time, the rotation of the driving rod 15 will drive the round block 11, thereby causing the round block 11 and the long plate 10 to move downward as a whole, thereby increasing the downward pressure of the cleaning brush 8 during cleaning.

[0024] In this design, a No. 1 connecting plate 16 is fixedly connected to both the left and right ends of the front side of the upper surface of the side plate 2. The rear surface of the No. 1 connecting plate 16 is movably connected to the front surface of the movable plate 7. A limit rod 17 is fixedly connected to the rear surface of the No. 1 connecting plate 16. The rear end of the limit rod 17 passes through the movable plate 7 and extends to the rear of the movable plate 7. The outer surface of the limit rod 17 is movably sleeved with the inner surface of the movable plate 7. The design of the limit rod 17 allows the movable plate 7 to move only along the outer surface of the limit rod 17, thereby limiting the overall movement direction of the movable plate 7. The No. 1 connecting plate 16, on the other hand, limits the overall movement range of the movable plate 7.

[0025] The rear end of the outer surface of the limiting rod 17 is movably sleeved with a collar 18. The rear surface of the collar 18 is fixedly connected to a second connecting plate 19. The outer surface of the second connecting plate 19 is movably sleeved with a first screw 20. The bottom end of the first screw 20 passes through the second connecting plate 19 and the side plate 2 and extends into the interior of the side plate 2. The outer surface of the first screw 20 and the inner surface of the side plate 2 are threaded together. The design of the first screw 20 allows the operator to remove the collar 18 and the second connecting plate 19. At this time, the entire movable plate 7 can be moved to the rear side of the limiting rod 17, thereby realizing the disassembly and replacement of the entire movable plate 7.

[0026] Among them, the upper surface of the active wavelength division multiplexer 1 is fixedly connected to a heat sink 21, which is made of aluminum alloy. The design of numerous heat dissipation fins on the outer surface of the heat sink 21 can increase the contact area between the heat sink 21 and the air, accelerate heat dissipation, and the material of the heat sink 21 has excellent heat dissipation speed. The combination of the two can realize the passive heat dissipation function.

[0027] Among them, the left and right sides of the outer surface of the heat sink 21 are fixedly connected to the sleeve block 22, the lower surface of the sleeve block 22 is movably connected to the fixing block 23, the bottom end of the fixing block 23 is fixedly connected to the upper surface of the active multiplexer 1, the inner surface of the sleeve block 22 is movably sleeved with the second screw 24, and the outer surface of the second screw 24 is threadedly sleeved with the inner surface of the fixing block 23. The design of the fixing block 23 serves to fix the heat sink 21 as a whole above the active multiplexer 1, and at the same time, the operator can remove the fixing block 23 to disassemble the heat sink 21 as a whole.

[0028] Working principle and usage process of this utility model:

[0029] First, the operator connects the optical fiber to the active wavelength division multiplexer 1 and starts the active wavelength division multiplexer 1. At this time, the active wavelength division multiplexer 1 will accurately separate or converge the optical signals transmitted by the optical fiber. The working principle of the active wavelength division multiplexer 1 is already well known to those skilled in the art and will not be elaborated on here. However, as the active wavelength division multiplexer 1 continues to operate, it will gradually start to heat up, most of which will be dissipated through the heat sink 21.

[0030] When the active wavelength division multiplexer 1 is placed in an open environment for a long time, dust will accumulate between the gaps of the heat sink 21 fins. At this time, the operator starts the first motor 3. As the first motor 3 runs, the circular shaft 4 and the driving rod 5 will start to rotate, and the driven rod 6 will start to rotate along with the rotation of the driving rod 5. At the same time, the other end of the driven rod 6 will drive the moving plate 7, thereby causing the moving plate 7 to start to move backward along the outer surface of the limit rod 17.

[0031] When the moving plate 7 contacts the heat sink 21, the operator starts the second motor 13. As the second motor 13 runs, the rotating shaft 14 and the driving rod 15 will start to rotate. The rotation of the driving rod 15 will drive the round block 11, causing the round block 11 and the long plate 10 to move downward as a whole. This increases the downward pressure of the cleaning brush 8 on the heat sink 21. Finally, under the combined action of the moving plate 7 and the cleaning brush 8, the dust in the gaps of the heat sink 21 will be cleaned, thus ensuring the stability of the heat dissipation function of the heat sink 21.
