[0003] The existing device is difficult to effectively dissipate heat, with low cooling efficiency, and unable to accurately control the cooling process of the optical fiber differential device, resulting in large temperature fluctuations, which is not conducive to ensuring the performance of the device and will also shorten the service life of the device. Summary of the Utility Model

[0004] The utility model discloses a 5G optical fiber differential protection device with a heat dissipation channel, aiming to solve the technical problems of difficult heat dissipation, low cooling efficiency, inability to accurately control temperature, large temperature fluctuations of the optical fiber differential device, and damage to performance and service life in the existing device.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A 5G optical fiber differential protection device with a heat dissipation channel includes a protection cabinet, and a heat dissipation component is arranged inside the protection cabinet. The heat dissipation component includes a servo motor, the power output shaft of the servo motor is connected to a rotating rod through a coupling, a movable seat is fixedly connected to the front end of the rotating rod, a sliding rod is movably connected inside the movable seat, one end of the sliding rod away from the servo motor is movably connected to a sliding member, a compression spring is fixedly connected to the side of the sliding member close to the sliding rod, the bottom end of the compression spring is fixedly connected between one side of the movable seat, a movable rod is movably connected inside the sliding member, both ends of the movable rod are movably connected to fixed rods, both ends of the fixed rods are fixedly connected between both ends of the inside of the protection cabinet, a cold head is fixedly connected to the front end of the sliding member, a water cooling pipe is fixedly connected to the rear end of the cold head, a cold conveying pipe is fixedly connected to the rear end of the cold head, the cold conveying pipe is located on one side of the water cooling pipe, and cold exhaust fans are fixedly connected to one ends of the water cooling pipe and the cold conveying pipe.

[0006] By providing a protection cabinet and a heat dissipation component, when the heat dissipation component starts to work, the servo motor starts to drive the rotating rod to rotate, and the movable seat fixedly connected to the front end also rotates accordingly. The sliding rod movably connected to the inner side of the movable seat will move relatively within the movable seat when the movable seat rotates due to factors such as centrifugal force. The slider movably connected to the front end of the sliding rod will displace along with the movement of the sliding rod. The compression spring fixedly connected to one side of the slider will be compressed or extended when the slider moves. When the slider moves outward, the compression spring is stretched; when the slider moves inward, the compression spring is compressed. The compression spring plays a role in buffering and resetting. The movable rod movably connected to the inner side of the slider is movably connected to the fixed rods at both ends, and the two ends of the fixed rods are fixedly connected to the inner ends of both sides of the protection cabinet. The movable rod and the fixed rods form a stable structure that restricts the movement trajectory of the slider, enabling it to move only in a specific direction. The cold head fixedly connected to the front end of the slider will move in position behind the optical fiber differential device along with the movement of the slider. The front end of the cold head contacts the rear end of the optical fiber differential device, and heat exchange begins. The hot air generated by the optical fiber differential device is absorbed by the cold head, then the hot air enters the water-cooled pipe through the cold head, and is then transmitted to the cold radiator fan by the water-cooled pipe. The heat dissipation channel composed of the cold radiator fan cools the hot air and converts it into cold air. The cold air after being cooled by the cold radiator fan is transmitted back to the cold head through the cold air pipe, and the cold head then transfers the cold air to the optical fiber differential device, thereby achieving the cooling of the optical fiber differential device. During this process, the heat can be effectively dissipated through the heat dissipation channel to achieve efficient cooling, and the cooling process of the optical fiber differential device can be precisely controlled to maintain it within a suitable temperature range, which is beneficial to improving the performance and service life of the device.

[0007] In a preferred solution, an observation window is fixedly connected to the front end of the protection cabinet, and a handle is fixedly connected to the front end of the protection cabinet, and the handle is located at the lower right of the observation window. A perforation is provided on one side of the protection cabinet, and a heat dissipation pipe is fixedly connected to the front end of the perforation. A rectangular hole is provided at the rear of the protection cabinet, and a fixed connection is made between the inner side of the rectangular hole and the outer side of the cold radiator fan. Heat dissipation plates are fixedly connected to both inner ends of the protection cabinet. The optical fiber differential device is arranged at the top of the heat dissipation plate, and the front end of the cold head contacts the rear end of the optical fiber differential device. A fixed frame is movably connected to the outer side of the rotating rod, and both ends of the fixed frame are fixedly connected to both inner ends of the protection cabinet.

[0008] In a preferred embodiment, a bottom cooling assembly is provided at the bottom end of the heat dissipation plate. The bottom cooling assembly includes a driving motor, and the bottom end of the driving motor is fixedly connected to the inner side of the bottom end of the protection cabinet. A rotating rod is fixedly connected to the power output shaft of the driving motor. A rotating shaft is fixedly connected to the top end of the rotating rod. An active member is fixedly connected to the outer side of the rotating shaft, and a water-cooled fan is fixedly connected to the top end of the active member. A rotating gear is movably connected to the inner side of the active member. A gear ring is movably connected to the outer side of the rotating gear, and the gear ring and the rotating gear are engaged with each other through tooth grooves. Symmetrical connecting frames are movably connected to the top end of the gear ring, and the top ends of the connecting frames are fixedly connected to the bottom end of the heat dissipation plate.

[0009] By providing the bottom cooling assembly, when the bottom cooling assembly starts to work, the driving motor is powered on and starts to drive the rotating rod to rotate. The rotating rod transmits the power to the rotating shaft at the top end, causing the rotating shaft to start rotating. The active member fixedly connected to the outer side will rotate along with the rotation of the rotating shaft, and the water-cooled fan fixedly connected to the top end of the active member will also rotate accordingly. During the rotation process, the water-cooled fan will generate an air flow to stir the air around the bottom of the heat dissipation plate, playing a preliminary cooling role. At the same time, the rotating gear movably connected to the inner side of the active member will also rotate along with the rotation of the active member. When the rotating gear rotates, it will engage with the gear ring on the outer side through the tooth grooves. Because the gear ring and the rotating gear are engaged, the rotation of the rotating gear will drive the gear ring to rotate. Under the dual action of the air flow generated by the water-cooled fan and its own rotation, the heat dissipation plate can more effectively cool the bottom of the optical fiber differential device, expanding the cooling range and improving the cooling effect.

[0010] As can be seen from the above, a 5G optical fiber differential protection device with a heat dissipation channel provided by the present utility model has the technical effects of effectively dissipating heat through the heat dissipation channel to achieve efficient cooling, accurately controlling the cooling process of the optical fiber differential device, maintaining it within a suitable temperature range, and being beneficial to improving the performance and service life of the device.

A water cooling pipe 610 is connected to the rear end of the cold head 607 through bolts. A cold air delivery pipe 611 is connected to the rear end of the cold head 607 through bolts. The cold air delivery pipe 611 is located on one side of the water cooling pipe 610. One ends of the water cooling pipe 610 and the cold air delivery pipe 611 are both connected to a cold air exhaust fan 612 through bolts.

[0020] Refer to Figure 1 , Figure 2 and Figure 3 , in a preferred embodiment, an observation window 3 is connected to the front end of the protection cabinet 1 through bolts. A handle 4 is connected to the front end of the protection cabinet 1 through bolts, and the handle 4 is located at the lower right of the observation window 3. A perforation is formed on one side of the protection cabinet 1. A heat dissipation pipe 2 is connected to the front end of the perforation through bolts. A rectangular hole is formed on the rear side of the protection cabinet 1, and the inside of the rectangular hole is connected to the outside of the cold air exhaust fan 612 through bolts. Heat dissipation plates 7 are connected to both ends inside the protection cabinet 1 through bolts. A fiber differential device 5 is arranged at the top of the heat dissipation plate 7, and the front end of the cold head 607 is in contact with the rear end of the fiber differential device 5. A fixed bracket 9 is connected to the outside of the rotating rod 602 through rotational connection. Both ends of the fixed bracket 9 are connected to both ends inside the protection cabinet 1 through bolts.

[0021] Refer to Figure 2 , Figure 3 and Figure 5, in a preferred embodiment, a bottom cooling component 8 is provided at the bottom end of the heat dissipation plate 7. The bottom cooling component 8 includes a driving motor 801, and the bottom end of the driving motor 801 is bolted to the inner bottom end of the protection cabinet 1. The power output shaft of the driving motor 801 is bolted with a rotating rod 802. The top end of the rotating rod 802 is bolted with a rotating shaft 803. An active part 804 is bolted to the outside of the rotating shaft 803, and a water-cooled fan 805 is bolted to the top end of the active part 804. A rotating gear 806 is rotatably connected to the inside of the active part 804. A gear ring 807 is rotatably connected to the outside of the rotating gear 806. The gear ring 807 and the rotating gear 806 are engaged through tooth grooves. Symmetrical connecting frames 808 are rotatably connected to the top end of the gear ring 807. The top ends of the connecting frames 808 are bolted to the bottom end of the heat dissipation plate 7.

[0022] Working principle: When the heat dissipation component 6 starts to work, the servo motor 601 starts to drive the rotating rod 602 to rotate. The movable seat 603 fixedly connected to the front end also rotates accordingly. When the movable seat 603 rotates, the sliding rod 604 movably connected to the inner side of the movable seat 603 will move relative to the movable seat 603 due to factors such as centrifugal force. The sliding member 606 movably connected to the front end of the sliding rod 604 will displace with the movement of the sliding rod 604. The compression spring 605 fixedly connected to one side of the sliding member 606 will be compressed or extended when the sliding member 606 moves. When the sliding member 606 moves outwards, the compression spring 605 is stretched; when the sliding member 606 moves inwards, the compression spring 605 is compressed. The compression spring 605 plays a role in buffering and resetting. The movable rod 608 movably connected to the inner side of the sliding member 606 is movably connected to the fixed rod 609 at both ends, and the two ends of the fixed rod 609 are fixedly connected to the inner ends of both sides of the protection cabinet 1. The movable rod 608 and the fixed rod 609 form a stable structure, restricting the movement trajectory of the sliding member 606 so that it can only move along a specific direction. The cold head 607 fixedly connected to the front end of the sliding member 606 will move in position behind the optical fiber differential device 5 with the movement of the sliding member 606. When the front end of the cold head 607 contacts the rear end of the optical fiber differential device 5, heat exchange starts. The hot air generated by the optical fiber differential device 5 is absorbed by the cold head 607, and then the hot air enters the water-cooling pipe 610 through the cold head 607 and is then transmitted to the cold radiator fan 612 by the water-cooling pipe 610. The heat dissipation channel composed of the cold radiator fan 612 realizes the heat dissipation treatment of the hot air by the cold radiator fan 612. The cold radiator fan 612 dissipates the heat of the hot air and converts it into cold air. The cold air after being dissipated by the cold radiator fan 612 is transmitted back to the cold head 607 through the cold air transmission pipe 611, and the cold head 607 then transfers the cold air to the optical fiber differential device 5, thereby realizing the cooling of the optical fiber differential device 5. When the bottom cooling component 8 starts to work, the driving motor 801 is powered on and starts to drive the rotating rod 802 to rotate. The rotating rod 802 transmits the power to the rotating shaft 803 at the top, causing the rotating shaft 803 to start rotating. The movable member 804 fixedly connected to the outside will rotate with the rotation of the rotating shaft 803. The water-cooling fan 805 fixedly connected to the top of the movable member 804 also rotates accordingly. The water-cooling fan 805 generates an air flow during rotation, stirring the air around the bottom of the heat dissipation plate 7 and playing a preliminary cooling role. At the same time, the rotating gear 806 movably connected to the inner side of the movable member 804 also rotates with the rotation of the movable member 804. When the rotating gear 806 rotates, it meshes with the outer gear ring 807 through the tooth grooves. Because the gear ring 807 meshes with the rotating gear 806, the rotation of the rotating gear 806 drives the gear ring 807 to rotate.

The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present utility model and its inventive concept shall be covered within the protection scope of the present utility model.
