[0002] Optical communication equipment uses light waves as the transmission medium to transmit information. Compared with traditional electrical signal transmission, optical communication has a higher transmission speed and a longer transmission distance. However, when optical communication equipment is in use, it will generate high temperature. In order to avoid affecting the use, a heat dissipation mechanism will be used to dissipate heat from the optical communication equipment;

[0003] Referring to a fixing device for optical communication equipment with a publication number of CN213018718U, its bottom plate is fixed to the second slider through screws, and then the equipment is placed between a pair of clamping plates. The width of the pair of clamping plates can be adjusted by the telescopic tension of the first linear motor, so as to fix equipment of different models. Then, a fan is used to dissipate heat from the equipment, and a timer is installed inside to work regularly. Then, during maintenance, the second linear motor can be used to drive the second slider to move downward, so that the bottom plate moves downward, facilitating the maintenance by the staff. However, there are still the following problems:

[0004] In the actual use of the above device, although the fan rotates to dissipate heat from the optical communication equipment, although the fan can blow air towards the optical communication equipment, impurities in the air will also be adsorbed on the surface of the optical communication equipment along with the air flow. Therefore, after long-term use, dust will affect the heat dissipation performance of the optical communication equipment.

A filter screen 11 is fixed inside the housing 1;

[0034] Reference Figures 1 to 4 , the output end of the motor 4 drives the blade 5 to rotate, so that the rotation of the blade 5 can transport the outside air into the housing 1, and then the flowing air can cool the heat generated on the circuit board 3, thus achieving the purpose of cooling. The air passing through the filter screen 11 will be filtered, and then the impurities in the air can be separated, and then the relatively clean air can play a role in heat dissipation, thus avoiding the decrease of heat dissipation caused by impurities adsorbed on the circuit board 3;

[0035] Embodiment 2:

[0036] The utility model solves the problem that the filter screen 11 in Embodiment 1 will affect the air permeability due to the adsorption of dust after long-term use, thus resulting in a decrease in heat dissipation. The dust can be cleaned by the movement of the brush bristles 10. It discloses:

[0037] The output end of the motor 4 is connected to the bottom of a rotating rod 7 through a bevel gear set 6, and the bevel gear set 6 rotates inside the housing 1. The rotating rod 7 is connected to the inside of the housing 1 through a bearing, and the top of the rotating rod 7 is connected to the top of a reciprocating lead screw 9 through a pulley set 8. The reciprocating lead screw 9 is connected to the inside of the housing 1 through a bearing. A brush bristle 10 is threadedly connected to the reciprocating lead screw 9, and the outer end of the brush bristle 10 is slidably engaged inside the housing 1, and the inner end of the brush bristle 10 and the filter screen 11 form a fitting mechanism;

[0038] Reference Figures 1 to 4 , the output end of the motor 4 drives the bevel gear set 6 to rotate, so that the rotation of the bevel gear set 6 drives the rotating rod 7 to rotate, and then the rotation of the rotating rod 7 drives the reciprocating lead screw 9 to rotate through the pulley set 8, and then the rotation of the reciprocating lead screw 9 drives the brush bristle 10 to move inside the housing 1, so that the movement of the brush bristle 10 can clean the impurities on the surface of the filter screen 11, thus avoiding the blockage caused by the adsorption of impurities on the surface of the filter screen 11;

[0039] Embodiment Three:

[0040] The utility model solves the problem that when the bristles 10 clean dust in Embodiment Two, the dust will fall to the ground and is inconvenient to clean. The collecting groove 12 can collect the dust for convenient unified treatment, and discloses:

[0041] The outer wall of the housing 1 is attached with a collecting groove 12, and the inner end of the collecting groove 12 is nested with a first magnet 13, and an adsorption mechanism is formed between the inner end of the first magnet 13 and the second magnet 14. The second magnet 14 is nested inside the housing 1. A convex block 15 slides at the inner end of the collecting groove 12, and the outer end of the convex block 15 is semicircularly arranged, and the outer end of the convex block 15 extends into the inside of the groove 16 to form a clamping mechanism. The groove 16 is opened inside the housing 1. The inner end of the convex block 15 is connected with a spring 17, and the inner end of the spring 17 is connected inside the collecting groove 12;

[0042] Reference Figure 1 , Figure 2 , Figures 5 to 7 , the impurities brushed off by the bristles 10 will enter the inside of the collecting groove 12 for collection. By pulling the collecting groove 12, the movement of the collecting groove 12 can drive the first magnet 13 to move, so that the first magnet 13 moves away from the adsorption of the second magnet 14, and the movement of the collecting groove 12 will drive the convex block 15 to move, so that the movement of the convex block 15 will squeeze the groove 16, so that the convex block 15 is squeezed and moves into the inside of the collecting groove 12, and the movement of the convex block 15 will squeeze the spring 17, so that the spring 17 is compressed by the force, so that the convex block 15 moves away from the clamping of the groove 16, and then it is convenient to disassemble the collecting groove 12 for unified treatment of dust impurities. By reversing the above operations, the collecting groove 12 can be quickly installed.

[0043] Working principle: When using this heat dissipation structure for an optical communication device, first, reference Figures 1 to 4 , the output end of the motor 4 drives the blade 5 to rotate, and then the flowing air can cool the heat generated on the circuit board 3. The air passes through the filter screen 11 and will be filtered, and then the impurities in the air can be separated, and then the relatively clean air plays a role in heat dissipation, so as to avoid the adsorption of impurities on the circuit board 3 resulting in a decrease in heat dissipation performance;

[0044] Reference Figures 1 to 4 , the output end of the motor 4 drives the bevel gear set 6 to rotate, and then the rotation of the bevel gear set 6 drives the rotating rod 7 to rotate, and then the reciprocating lead screw 9 rotates to drive the bristles 10 to move inside the housing 1, so as to avoid the blockage of the surface of the filter screen 11 due to the adsorption of impurities;

[0045] Reference Figure 1 、 Figure 2 、 Figures 5 to 7 The impurities brushed off by the bristles 10 will enter the interior of the collection trough 12 for collection. By pulling the collection trough 12, the movement of the collection trough 12 can drive the first magnet 13 to move, and the movement of the collection trough 12 will drive the bump 15 to move, so that the movement of the bump 15 will squeeze the groove 16, causing the bump 15 to move into the interior of the collection trough 12 under extrusion. The movement of the bump 15 will squeeze the spring 17, causing the spring 17 to be compressed under force, thus facilitating the disassembly of the collection trough 12 for unified treatment of dust and impurities. By reversing the above operations, the collection trough 12 can be quickly installed.
