Description

Technical Field

[0001] The present invention relates to the field of network devices, and particularly to a highly protected and highly sealed non-jumping optical cable distribution box. Background Art

[0002] A non-jumping optical cable distribution box is an optical cable distribution box that does not require fiber-jumping connection. Its structural design avoids the redundant accumulation of fiber-jumping, facilitates the search for and scheduling of the optical serial numbers of the optical paths, and is more convenient for maintenance. The working environment of the non-jumping optical cable distribution box is basically outdoors. Therefore, its protection and sealing are particularly important.

[0003] To achieve heat dissipation inside, the existing non-jumping optical cable distribution boxes usually need to be equipped with cooling fans to introduce external air for heat dissipation. However, in rainy days or in weather with high humidity, rainwater or fog is likely to enter the interior of the distribution box, which poses a relatively large potential safety hazard. Summary of the Invention

[0004] The purpose of the present invention is to provide a highly protected and highly sealed non-jumping optical cable distribution box to solve the above problems.

[0005] The above technical objective of the present invention is achieved through the following technical solutions: A highly protected and highly sealed non-jumping optical cable distribution box includes a box body, and two brackets are fixedly installed inside the box body;

[0006] Heat conduction boxes are fixedly installed on both sides of the bracket. A heat conduction groove communicating with the external space is opened backward in the heat conduction box. A set of guide rails is fixedly arranged in the heat conduction groove. The guide rails are composed of a first guide rail bar, a second guide rail bar, and a third guide rail bar. Part of the first guide rail bar is located inside the heat conduction groove and part of it extends to the outside. The second guide rail bar and the third guide rail bar are both located on the back side of the box body. A heat conduction component is installed between the third guide rail bars. The heat conduction component includes a plurality of heat conduction bars slidably arranged between the guide rails. The heat conduction bars include heat conduction sheets. Connecting rods are fixed at both ends of the heat conduction sheets. Sliders slidably installed in the guide rails are fixed at the ends of the connecting rods. The heat conduction sheets are fixed to each other through a connecting layer;

[0007] A first motor fixed to the box body is arranged on one side of the heat conduction component. A first winding wheel is fixed on the motor shaft of the first motor. A first pulling wire is wound around the first winding wheel. One end of the first pulling wire is fixed on a first rotating cylinder. The first rotating cylinder is rotatably installed on the connecting rod of the heat conduction component closest to the first motor;

[0008] A second motor is fixedly installed on each of the heat conduction boxes. A rotating shaft inserted into the heat conduction groove is fixed on the motor shaft of the second motor. A second winding wheel is fixedly installed at the end of the rotating shaft. A second pulling wire is wound around the second winding wheel. One end of the second pulling wire is fixed on a second rotating cylinder, and the second rotating cylinder is rotatably installed on the connecting rod at the outermost side of the heat conduction assembly.

[0009] A control terminal is integrated in the box body, and a temperature sensor is also installed in the box body.

[0010] Preferably, the connecting layer is made of rubber or plastic.

[0011] Preferably, both the heat conduction box and the heat conduction fin are made of aluminum or copper.

[0012] Preferably, the thickness of the heat conduction fin is the same as the width of the heat conduction groove.

[0013] Preferably, the slider is spherical, and the cross-section of the groove fitted in the guide rail is also spherical.

[0014] Preferably, a protection component is additionally installed outside the two heat conduction assemblies. The protection component includes a box body fixed on the back side of the box body. Ventilation holes are evenly opened on the box body, and a rainproof plate fixed to the box body is arranged outside the ventilation holes.

[0015] Preferably, a plurality of fans fixed to the box body are installed in the box body.

[0016] Preferably, a placement box and an electric telescopic rod are fixedly installed in the box body. The electric telescopic rod is located at the top of the placement box. A pressing spray bottle is placed in the placement box. The pressing spray bottle is filled with alcohol. The electric telescopic rod controls a telescopic rod, and the telescopic rod is located directly above the pressing spray bottle.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. In this application, heat conduction boxes are fixedly installed on both sides of the bracket. A heat conduction groove communicating with the external space is opened backward in the heat conduction box. A set of guide rails are fixedly arranged in the heat conduction groove. A heat conduction assembly is installed between the third guide rail strips. Heat absorption and heat dissipation are carried out through the heat conduction assembly and the heat conduction box, which can prevent rainwater from entering the box body. While ensuring the heat dissipation effect, the overall sealing performance and safety are greatly enhanced.

[0019] 2. The heat conduction component includes several heat conduction bars slidably arranged between the guide rails. Each heat conduction bar includes a heat conduction sheet. Connecting rods are fixed to both ends of the heat conduction sheet, and sliders slidably installed in the guide rails are fixed to the ends of the connecting rods. The heat conduction sheets are fixed to each other through a connecting layer, which can be made of soft materials such as rubber or plastic. This facilitates the movement of the heat conduction component along the guide rails. Compared with an integrated heat conduction plate, such a flexible heat conduction component occupies less longitudinal space as a whole, resulting in a smaller overall volume.

[0020] 3. The thickness of the heat conduction sheet is the same as the width of the heat conduction groove, ensuring that the heat conduction sheet can fit perfectly with the heat conduction box after entering the heat conduction groove, guaranteeing excellent heat absorption effect.

[0021] 4. A number of fans fixed to the box body are installed inside the box. After the fans are started, they can blow the outside air to the surface of the heat conduction component for heat dissipation. At the same time, after the fans are started, they can also directly blow the outside air into the heat conduction groove to dissipate heat from the heat conduction box, enhancing the heat dissipation effect.

[0022] 5. A placement box and an electric telescopic rod are fixedly installed inside the box. The electric telescopic rod is located at the top of the placement box. A pressing spray bottle is placed inside the placement box, and the pressing spray bottle is filled with alcohol. The electric telescopic rod controls a telescopic rod, which is located directly above the pressing spray bottle. After the electric telescopic rod is started, it controls the telescopic rod to extend. The telescopic rod presses the pressing spray bottle, spraying the alcohol inside the pressing spray bottle onto the heat conduction component. In cooperation with the fan, it accelerates the evaporation of alcohol and quickly takes away the heat on the surface of the heat conduction component. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0030] Combined with the attached Figures 1-5 For the described highly protected and highly sealed non-jumping optical cable cross-connect box, it includes a box body 11. Two brackets 12 are fixedly installed inside the box body 11. An integrated fiber optic splice tray is installed between the two brackets 12. As for the number of cores of the integrated fiber optic splice tray, it can be adjusted according to actual needs;

[0031] This application adopts the form of conduction heat dissipation. Specifically, heat conduction boxes 13 are fixedly installed on both sides of the bracket 12. Heat conduction grooves 33 communicating with the external space are opened backward inside the heat conduction boxes 13. A set of guide rails 40 are fixedly arranged in each of the heat conduction grooves 33. The guide rails 40 are composed of a first guide rail bar 21, a second guide rail bar 19, and a third guide rail bar 22. Part of the first guide rail bar 21 is located inside the heat conduction groove 33 and part extends to the outside. Both the second guide rail bar 19 and the third guide rail bar 22 are located on the back side of the box body 11. A heat conduction component is installed between the third guide rail bars 22. The heat conduction component includes a number of heat conduction bars slidably arranged between the guide rails 40. The heat conduction bars include heat conduction sheets 30. Connecting rods 32 are fixed at both ends of the heat conduction sheets 30. The ends of the connecting rods 32 are fixed with sliders 39 slidably installed in the guide rails 40. Each of the heat conduction sheets 30 is fixed through a connection layer 31;

[0032] A first motor 25 fixed to the box body 11 is arranged on one side of the heat conduction component. A first winding wheel 23 is fixed on the motor shaft of the first motor 25. A first pull wire 24 is wound on the first winding wheel 23. One end of the first pull wire 24 is fixed on a first rotating cylinder 35. The first rotating cylinder 35 is rotatably installed on the connecting rod 32 of the heat conduction component closest to the first motor 25;

[0033] A second motor 14 is fixedly installed on each of the heat conduction boxes 13. A rotating shaft 34 inserted into the heat conduction groove 33 is fixed on the motor shaft of the second motor 14. A second winding wheel 38 is fixedly installed at the end of the rotating shaft 34. A second pulling wire 20 is wound around the second winding wheel 38. One end of the second pulling wire 20 is fixed on a second rotating cylinder 36. The second rotating cylinder 36 is rotatably installed on the connecting rod 32 at the outermost side of the heat conduction assembly.

[0034] A control terminal is integrated in the box body 11. A temperature sensor 37 is also installed in the box body 11. When the temperature sensor 37 detects that the temperature in the box body 11 is too high, it feeds back to the control terminal. The control terminal controls the start of the second motor 14 and the first motor 25. The start of the second motor 14 drives the rotation of the rotating shaft 34 and the second winding wheel 38. The second winding wheel 38 winds the second pulling wire 20. The start of the first motor 25 drives the rotation of the first winding wheel 23. The first winding wheel 23 relaxes the first pulling wire 24, thereby pulling the heat conduction assembly into the heat conduction groove 33. The heat in the box body 11 will be conducted to the heat conduction box 13 and then to the heat conduction assembly to be absorbed. After a period of time, the control terminal will control the second motor 14 and the first motor 25 to start in the reverse direction, pulling the heat conduction assembly out of the heat conduction groove 33 to cool the heat conduction assembly. If the temperature sensor 37 detects that the temperature in the box body 11 is still too high, the cooled heat conduction assembly will continue to be pulled into the heat conduction groove 33 for heat absorption until the temperature sensor 37 detects that the temperature in the box body 11 is within a reasonable range.

[0035] It should be especially noted that the connecting layer 31 can be made of soft materials such as rubber and plastic, which facilitates the movement of the heat conduction assembly along the guide rail 40. Compared with an integral heat conduction plate, the overall longitudinal space occupied by such a flexible heat conduction assembly is relatively small, making the overall volume smaller.

[0036] To ensure the heat absorption effect, both the heat conduction box 13 and the heat conduction sheet 30 are made of metal materials with good heat conductivity. Considering cost issues, aluminum or copper is the most suitable.

[0037] In addition, the thickness of the heat conduction sheet 30 is the same as the width of the heat conduction groove 33 to ensure that the heat conduction sheet 30 can be completely attached to the heat conduction box 13 after entering the heat conduction groove 33 to ensure the heat absorption effect.

[0038] Refer to Figure 5 , the slider 39 is spherical, and the cross-section of the groove in the guide rail 40 that it fits into is also spherical, facilitating the movement of the heat conduction assembly in the guide rail 40.

[0039] A protection component 50 is installed outside the two heat conduction components. The protection component 50 includes a box body 15 fixed to the back side of the box 11. The box body 15 is evenly provided with ventilation holes 16. A rainproof plate 17 fixed to the box body 15 is arranged outside the ventilation holes 16. The ventilation holes 16 are used for ventilation, and the rainproof plate 17 is used for rain protection.

[0040] To accelerate the cooling of the heat conduction components, a number of fans 18 fixed to the box body 15 are installed in the box body 15. After the fans 18 are started, they can blow the outside air to the surface of the heat conduction components for heat dissipation. At the same time, after the fans 18 are started, they can also directly blow the outside air into the heat conduction groove 33 to dissipate heat from the heat conduction box 13.

[0041] To further optimize the cooling effect of the heat conduction components, a placement box 29 and an electric telescopic rod 26 are fixedly installed in the box body 15. The electric telescopic rod 26 is located at the top of the placement box 29. A pressing spray bottle 28 is placed in the placement box 29. The pressing spray bottle 28 contains alcohol. The electric telescopic rod 26 controls a telescopic rod 27. The telescopic rod 27 is located directly above the pressing spray bottle 28. After the electric telescopic rod 26 is started, it controls the telescopic rod 27 to extend. The telescopic rod 27 presses the pressing spray bottle 28 to spray the alcohol in the pressing spray bottle 28 onto the heat conduction components. Cooperating with the fans 18, it accelerates the evaporation of alcohol and quickly takes away the heat on the surface of the heat conduction components.

[0042] The pressing spray bottle 28 is a directly purchased side-pressing spray bottle, and the alcohol in it needs to be added and replaced regularly.

[0043] The fan 18 is a directly purchased salt spray-proof fan and is not easily corroded after long-term use.

[0044] Usage method:

[0045] The temperature sensor 37 detects the temperature inside the box 11 in real time and feeds it back to the control terminal. When the temperature sensor 37 detects that the temperature is too high, the control terminal controls the second motor 14 and the first motor 25 to start. The second motor 14 starts to drive the rotating shaft 34 and the second winding wheel 38 to rotate. The second winding wheel 38 winds the second pull wire 20. The first motor 25 starts to drive the first winding wheel 23 to rotate. The first winding wheel 23 relaxes the first pull wire 24, thereby pulling the heat conduction component into the heat conduction groove 33. The heat inside the box 11 will be conducted to the heat conduction box 13 and then conducted to the heat conduction components and absorbed.

[0046] After a period of time, the control terminal will control the second motor 14 and the first motor 25 to start in the reverse direction. The start of the second motor 14 drives the rotation of the rotating shaft 34 and the second winding wheel 38. The second winding wheel 38 winds the second wire 20. The start of the first motor 25 drives the rotation of the first winding wheel 23. The first winding wheel 23 winds the first wire 24 to pull the heat conduction component out of the heat conduction groove 33 for reset. The control terminal controls the fan 18 and the electric telescopic rod 26 to start. The start of the fan 18 blows the outside air onto the heat conduction component for cooling. After the electric telescopic rod 26 starts, it controls the telescopic rod 27 to extend. The telescopic rod 27 presses the pressing spray bottle 28 to spray the alcohol in the pressing spray bottle 28 onto the heat conduction component. In cooperation with the fan 18, it accelerates the evaporation of the alcohol and quickly takes away the heat on the surface of the heat conduction component. The electric telescopic rod 26 controls the temperature sensor 37 to continuously extend and retract to continuously cool down;

[0047] After a period of time, if the temperature sensor 37 still detects that the temperature inside the box body 11 is too high, the control terminal will continue to pull the heat conduction component into the heat conduction groove 33 for heat absorption and cooling. After a period of time, the heat conduction component will be pulled out and work repeatedly until the temperature inside the box body 11 drops to the set range.

[0048] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention. The purpose is to enable those skilled in this field to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
