The heat dissipation fins 41 pass through the first groove 35 and extend into the heat dissipation groove 34. The end of the heat dissipation fin 41 away from the heat-conducting ring 4 contacts the inner wall of the first groove 35. The heat on the optical cable body 1 is transferred to the heat dissipation fin 41 through the heat-conducting ring 4. The heat dissipation area is increased by the heat dissipation fin 41, and the optical cable body 1 is dissipated, thereby improving the heat dissipation efficiency.

[0032] An arc-shaped fixing ring 36 is fixedly installed on the first clamping ring 31 and the second clamping ring 32. The two fixing rings 36 are both semicircular ring structures.

The airflow drives the pneumatic fan blades 39, the first rotating ring 37 and the second rotating ring 38 to rotate, and cooperates with the transmission mechanism to drive the heat dissipation mechanism to work, thereby accelerating the heat dissipation efficiency of the heat dissipation fins 41.

[0033] The heat dissipation mechanism consists of a third rotating ring 5 with a semicircular ring structure and heat dissipation fan blades 51. A second through groove 351 is provided on the inner wall of the first through groove 35. There are two second through grooves 351 in the same first through groove 35. The two first through grooves 35 are symmetrical to each other. A second rotating slide groove 352 is provided on the inner wall of the first through groove 35. The third rotating ring 5 is provided with two and is rotatably connected in the two second rotating slide grooves 352 respectively. The heat dissipation fan blades 51 are fixedly installed on the outer ring wall of the third rotating ring 5. There are several heat dissipation fan blades 51 and they are evenly distributed along the circumference of the third rotating ring 5. The optical cable winding column 2 is provided with a transmission mechanism, which drives the third rotating ring 5 to rotate through the transmission mechanism, so that the third rotating ring 5 drives the heat dissipation fan blades 51 to rotate, thereby increasing the flow of airflow in the heat dissipation groove 34, and thereby making the heat dissipation efficiency of the heat dissipation fan blades 51 higher.

[0034] The transmission mechanism consists of a transmission tooth 310, a linkage shaft 53, a first bevel gear 54, a second bevel gear 55 and a driven tooth 52. The transmission tooth 310 is fixedly mounted on a side of the first rotating ring 37 and the second rotating ring 38 close to the heat dissipation fan blade 51. The linkage shaft 53 is rotatably connected to the second clamping ring 32. The first bevel gear 54 and the second bevel gear 55 are respectively fixedly mounted on both ends of the linkage shaft 53. The driven tooth 52 is fixedly mounted on a side of the third rotating ring 5 close to the first rotating ring 37. The transmission tooth 310 meshes with the first bevel gear 54, and the driven tooth 52 meshes with the second bevel gear 55. The first rotating ring 37 and the second rotating ring 38 are driven to rotate through the pneumatic fan blade 39, so that the transmission tooth 310 drives the first bevel gear 54, the linkage shaft 53 and the second bevel gear 55 to rotate, and the second bevel gear 55 drives the driven tooth 52, the third rotating ring 5 and the heat dissipation fan blade 51 to rotate, so that a stronger airflow is generated in the heat dissipation slot 34.

[0035] A first water storage tank 311 with an arc structure is provided in the first clamping ring 31, a second water storage tank 321 with an arc structure is provided in the second clamping ring 32, a first water inlet 312 is provided on the top of the first clamping ring 31, a first filter plate 313 with an arc structure is fixedly installed on the inner wall of the first water inlet 312, a second water inlet 322 is provided on the second clamping ring 32, a second filter plate 323 is fixedly installed on the inner wall of the second water inlet 322, a plurality of first ventilation holes 314 are provided on both sides of the first clamping ring 31, the first ventilation holes 314 are connected to the first water storage tank 311, and a plurality of first ventilation holes 314 are provided on both sides of the second clamping ring 32. The second ventilation hole 324 is connected to the second water tank 321. Rainwater enters the first water tank 311 and the second water tank 321 respectively through the first water inlet 312 and the second water inlet 322. When the airflow passes through the first ventilation hole 314 and the second ventilation hole 324, it drives the rainwater in the first water tank 311 and the second water tank 321 to volatilize, thereby improving the efficiency of rainwater volatilization, and then absorbs and takes away the heat at the end of the heat dissipation fin 41, further improving the heat dissipation efficiency. The first filter plate 313 and the second filter plate 323 are respectively used to prevent impurities from entering the first water tank 311 and the second water tank 321.

[0036] An L-shaped cleaning strip 6 is fixedly mounted on the first rotating ring 37 , and a brush 61 is fixedly mounted on the bottom of the cleaning strip 6 . The brush 61 is driven to rotate by the pneumatic fan blades 39 to clean impurities on the first filter plate 313 and the second filter plate 323 .

[0037] A plurality of first dividing bars 315 are fixedly mounted on the inner wall of the first water storage tank 311, and a plurality of second dividing bars 325 are fixedly mounted on the inner wall of the second water storage tank 321. The first dividing bars 315 and the second dividing bars 325 are respectively used to separate the space within the first water storage tank 311 and the second water storage tank 321, so that rainwater can be distributed to various areas to a certain extent, thereby improving the uniformity of heat dissipation at the end of the heat dissipation fins 41.

[0038] A plurality of through holes 316 are formed on the first rotating ring 37 and the second rotating ring 38 . The through holes 316 facilitate airflow into the heat dissipation groove 34 to avoid being blocked by the first rotating ring 37 and the second rotating ring 38 .

[0039] The specific working principle and use method of the present invention are explained in detail below: When in use, the heat on the optical cable body 1 is transferred to the heat dissipation fins 41 through the heat conductive ring 4, and the air flow blows the pneumatic fan blades 39, so that the pneumatic fan blades 39 drive the first rotating ring 37 and the second rotating ring 38 to rotate, and the first rotating ring 37 and the second rotating ring 38 drive the transmission gear 310 to rotate, and the transmission mechanism drives the heat dissipation mechanism to rotate, and the heat dissipation fan blades 51 rotate to drive the air flow into the heat dissipation groove 34. Under the action of the air flow, the heat of the heat dissipation fins 41 is taken away, and then the optical cable body 1 is dissipated, thereby improving the heat dissipation efficiency;

[0040] Rainwater enters the first water tank 311 and the second water tank 321, and the airflow flows through the first ventilation hole 314 and the second ventilation hole 324, driving the volatilization of the rainwater in the first water tank 311 and the second water tank 321. Since the ends of the heat dissipation fins 41 are fixedly mounted on the inner wall of the heat dissipation groove 34, when the airflow drives the rainwater to volatilize, the heat at the ends of the heat dissipation fan blades 51 is absorbed by the rainwater and the heat is taken away by the volatilization of the rainwater, thereby further improving the heat dissipation efficiency and solving the problem of poor heat dissipation efficiency of the optical cable.

[0041] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
