Specific implementation mode

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0027] Please refer to Figures 1 to 6 , the present invention provides a high-efficiency heat dissipation type cable branch box, including a box body 1, a bracket 2, a heat dissipation exhaust pipe 3 and a dehumidification and heat dissipation component. The dehumidification and heat dissipation component includes two dehumidification boxes 4, an air inlet pipe 5 and a dehumidification scraper 6. The box body 1 has a dehumidification chamber 7 and a cooling chamber 8. The dehumidification and heat dissipation component further includes a heat preservation pad 9, a door panel 10 and a cooling unit. The cooling unit includes a cooling box 11, two air inlet pumps 12, a refrigerator 13, an air extraction pump 14 and two strengthening mechanisms. The box body 1 has a connecting groove 15 and a plurality of air inlet holes 16. The strengthening mechanism includes a fan 17, a heat absorption metal shaft 18, a plurality of heat absorption metal strips 19 and a plurality of extended heat dissipation components. The extended heat dissipation component includes a connecting block 20 and an extended heat dissipation block 21. The extended heat dissipation block 21 has a plurality of heat dissipation ports 22. The dehumidification box 4 includes a dehumidification box body 23, an exhaust valve 24, a plurality of heaters 25 and two dehumidification filter membranes 26. The dehumidification and heat dissipation component further includes a dehumidification switching unit. The dehumidification switching unit includes two three-way valves 27 and a plurality of connecting pipes 28. The dehumidification and heat dissipation component further includes a collection box 29, a slide block 30, a humidity sensor 31 and two scraping units. The scraping unit includes a driving component 34 and a threaded rod 35.

[0028] Among them, the bracket 2 is arranged inside the box body 1, the heat dissipation exhaust pipe 3 is communicated with one side of the box body 1, the box body 1 has a dehumidification chamber 7 and a cooling chamber 8, two dehumidification boxes 4 are symmetrically arranged in the dehumidification chamber 7, one end of the air inlet pipe 5 is communicated with the two dehumidification boxes 4, the other end of the air inlet pipe 5 is communicated with the box body 1, and the dehumidification scraper 6 is arranged inside the box body 1. By installing cables and adapters on the bracket 2, the circuit is built. The hot air inside the box body 1 is discharged through the heat dissipation exhaust pipe 3. At the same time, the external cold air is dehumidified through the two dehumidification boxes 4 and then enters the box body 1 through the air inlet pipe 5. And the dehumidification scraper 6 moves continuously to scrape the inner wall of the box body 1 to prevent water droplets from accumulating on the inner wall of the box body 1. Thus, the water droplets can be scraped out regularly, and at the same time, the humidity is reduced, the generation of water droplets is reduced, the short circuit damage of the cables and connectors is avoided, and the circuit safety is greatly improved.

[0029] Secondly, the heat preservation pad 9 is fixedly connected to the box body 1 and sleeved on the outer wall of the box body 1. The door panel 10 is rotatably connected to the box body 1, and the cooling unit is arranged inside the box body 1; the box body 1 has a communication groove 15 and a plurality of air inlet holes 16. The cooling box 11 is placed inside the dehumidification chamber 7. Two air inlet pumps 12 are symmetrically arranged on the inner side wall of the dehumidification chamber 7. The air outlet ends of the two air inlet pumps 12 are communicated with the cooling box 11. The refrigerator 13 is arranged on the cooling box 11. The air extraction pump 14 is arranged above the cooling box 11. Two strengthening mechanisms are symmetrically arranged on the cooling box 11 and are located inside the cooling chamber 8. The heat preservation pad 9 can play a role in heat preservation and heat insulation, prevent a large number of water droplets from being generated due to too large a temperature difference between the inside and outside of the box body 1, and reduce the generation of water droplets. After the door panel 10 is opened, it is convenient for the staff to install cables and connectors; when cooling air intake is carried out, the air inlet pump 12 is started, and the external air is drawn into the cooling box 11. There is coolant stored in the cooling box 11. The coolant is cooled by the refrigerator 13. Then, after the external air contacts the coolant, it is fully cooled and becomes cold air. The cold air floats in the cooling box 11. Then, the air extraction pump 14 is started to draw the cold air floating out of the coolant liquid level into the dehumidification box 4.

[0030] Meanwhile, the fan 17 is disposed inside the cooling bin 8. The heat-absorbing metal shaft 18 penetrates through the box body 1 and the cooling box 11. The heat-absorbing metal shaft 18 is rotatably connected to the box body 1 and the cooling box 11. A plurality of heat-absorbing metal strips 19 are sequentially disposed outside the heat-absorbing metal shaft 18 and are all located inside the cooling box 11. A plurality of extended heat dissipation components are sequentially distributed around one end of the heat-absorbing metal shaft 18 away from the heat-absorbing metal strips 19 and are all located inside the cooling bin 8. The extended heat dissipation block 21 has a plurality of heat dissipation openings 22. The connecting block 20 is fixedly connected to the heat-absorbing metal shaft 18 and is located at one end of the heat-absorbing metal shaft 18 away from the cooling bin 8. The extended heat dissipation block 21 is fixedly connected to the connecting block 20. When cooling the external air, the heat-absorbing metal shaft 18 absorbs the temperature of the coolant. The heat-absorbing metal strips 19 can enhance the heat absorption effect, and then transfer the heat to the extended heat dissipation components. At the same time, the fan 17 is started to drive the air to contact the extended heat dissipation block 21. Under the principle of metal heat conduction, the coolant is cooled. Thus, the temperature of the heat-absorbing metal shaft 18 does not rise, so that the heat absorption of the coolant can be continuously carried out, maintaining a good cooling temperature and continuously cooling the external cold air. At the same time, when the fan 17 blows, the air can blow through the heat dissipation openings 22, thereby increasing the contact area between the extended heat dissipation block 21 and the air and improving the heat dissipation effect. At the same time, since the heat-absorbing metal shaft 18 is rotatably disposed, a plurality of the extended heat dissipation blocks 21 can be driven to rotate. Finally, the connecting block 20 and the extended heat dissipation block 21 are in full contact with the air in the cooling bin 8, greatly improving the cooling effect of the coolant.

[0031] In addition, the dehumidification box body 23 is disposed inside the dehumidification bin 7 and is located above the cooling box 11. The exhaust valve 24 is disposed on the dehumidification box body 23. A plurality of heaters 25 are sequentially disposed inside the dehumidification box body 23. Two dehumidification filter membranes 26 are sequentially disposed inside the dehumidification box body 23 and are located between the plurality of heaters 25. The dehumidification box body 23 supports the dehumidification box 4. After the wet air enters the dehumidification box body 23, it is filtered for moisture through the dehumidification filter membrane 26 and then discharged. When drying is required for repeated use, the heaters 25 are started to dry the dehumidification filter membrane 26. At the same time, the exhaust valve 24 is opened, and the generated water vapor is discharged from the exhaust valve 24.

[0032] Then, the two three-way valves 27 are sequentially arranged inside the dehumidification chamber 7. One ends of multiple connecting pipes 28 are respectively communicated with the corresponding three-way valves 27, and the other ends of the multiple connecting pipes 28 are respectively communicated with the corresponding dehumidification box bodies 23. The air extraction pump 14 is communicated with the corresponding three-way valve 27, and one end of the air inlet pipe 5 is communicated with the corresponding three-way valve 27. When the humidity sensor 31 detects that the humidity inside the box body 1 has increased, it indicates that the dehumidification effect of the dehumidification filter membrane 26 is decreasing. At this time, the three-way valve 27 can be started, so that the wet air is conveyed through the other two connecting pipes 28, thereby achieving the effect of replacing the dehumidification box 4. At this time, the unused dehumidification box 4 can start the drying operation for subsequent repeated use.

[0033] Again, the humidity sensor 31 is arranged inside the box body 1. Two scraping units are symmetrically arranged inside the box body 1. The box body 1 has a plurality of drainage grooves 32 and sliding grooves 33. The slider 30 is slidably connected with the sliding groove 33. The collection box 29 is fixedly connected with the slider 30 and is located below the slider 30. When the scraping unit is started, it drives the dehumidification scraper 6 to scrape off water droplets. The water droplets flow along the inner wall of the box body 1 to the inner bottom wall of the box body 1, and then are discharged through the drainage grooves 32. At this time, they enter the collection box 29 for collection. After being filled, the collection box 29 is pulled out, and by sliding the slider 30 in the sliding groove 33, the collection box 29 can be quickly taken away for processing.

[0034] Moreover, the driving component 34 is arranged inside the box body 1. The output end of the driving component 34 is fixedly connected with one end of the threaded rod 35, and the other end of the threaded rod 35 is rotatably connected with the box body 1. The dehumidification scraper 6 has a threaded hole 36, and the threaded rod 35 is mutually adapted to the threaded hole 36. The driving component 34 is a motor. When the driving component 34 is started, it drives the threaded rod 35 to rotate. Cooperating with the threaded hole 36, the dehumidification scraper 6 can be driven to move up and down.

[0035] When using an efficient heat dissipation type cable distribution box according to this embodiment, the cable and the adapter are installed on the bracket 2 to build the circuit. The heat preservation pad 9 can play a role in heat preservation and heat insulation, avoiding a large temperature difference between the inside and outside of the box body 1 and generating a large amount of water droplets, reducing the generation of water droplets. After the door panel 10 is opened, it is convenient for the staff to install the cable and the connector. When cooling air intake is carried out, the intake pump 12 is started, and external air is pumped into the cooling box 11. There is a coolant stored in the cooling box 11. The coolant is cooled by the refrigerator 13. Then, after the external air contacts the coolant, it is fully cooled and becomes cold air. The cold air floats in the cooling box 11. Then the air extraction pump 14 is started to pump the cold air floating on the liquid surface of the coolant into the dehumidification box body 23. At the same time, the heat absorption metal shaft 18 absorbs the temperature of the coolant, and the heat absorption metal strip 19 can enhance the heat absorption effect, and then transfer the heat to the extended heat dissipation component. Then the fan 17 is started to drive the air to contact the extended heat dissipation block 21. Under the principle of metal heat conduction, the coolant is cooled. Thus, the temperature of the heat absorption metal shaft 18 does not rise, so that the heat of the coolant can be continuously absorbed, maintaining a good cooling temperature and continuously cooling the external cold air. At the same time, when the fan 17 blows, the air can blow through the heat dissipation port 22, which can increase the contact area between the extended heat dissipation block 21 and the air, improving the heat dissipation effect. At the same time, since the heat absorption metal shaft 18 is rotatably arranged, it can blow multiple extended heat dissipation blocks 21 to rotate. Finally, the connecting block 20 and the extended heat dissipation block 21 are in full contact with the air in the cooling bin 8, greatly improving the cooling effect of the coolant. Finally, after the wet air enters the dehumidification box body 23, it is filtered by the dehumidification filter membrane 26 and then discharged. When drying is required for repeated use, the heater 25 is started to dry the dehumidification filter membrane 26. At the same time, the exhaust valve 24 is opened, and the generated water vapor is discharged from the exhaust valve 24. Then the dehumidified cold air enters the inside of the box body 1 from the intake pipe 5. The driving component 34 is started to drive the threaded rod 35 to rotate. Cooperating with the threaded hole 36, the dehumidification scraper 6 can be driven to move up and down to scrape the inner wall of the box body 1, avoiding water droplets from accumulating on the inner wall of the box body 1. Through the above structural settings, water droplets can be scraped out regularly, and at the same time, the humidity is reduced, the generation of water droplets is reduced, and the short circuit damage of the cable and the connector is avoided, greatly improving the safety of the circuit.

[0036] Please refer to Figure 7, the present invention also provides an efficient heat dissipation type cable branch system, including the above-mentioned efficient heat dissipation type cable branch box, and further including a cable branch box fixed installation module 37, an air dust removal module 38, a coolant replacement module 39 and a line installation module 40. The box body 1, the branch box fixed installation module, the air dust removal module 38, the coolant replacement module 39 and the line installation module 40 are connected in sequence.

[0037] Among them, the cable branch box fixed installation module 37 is used to install the overall structure of the box body 1 to enable it to be stably used outdoors and avoid deviation; the air dust removal module 38 is used to filter the dust in the air entering the cooling box 11, thereby reducing the pressure of the coolant to filter dust, improving the service life of the coolant, and preventing the coolant from being contaminated by dust after use; the coolant replacement module 39 is used for the staff to replace the coolant to ensure the air cooling effect; the line installation module 40 is used to set a robotic arm, and then automatically install the cable and the connector after the door panel 10 is opened.
