[0037] The support frame 61 is made of calcium silicate insulation board, and the interior of the box 1 is provided with calcium silicate insulation board; specifically, the calcium silicate insulation board has an extremely low thermal conductivity coefficient and can effectively prevent the transfer of heat, which makes the temperature inside the box 1 more stable, and can reduce the impact of the external temperature on the interior of the box 1 whether in a high temperature environment or a low temperature environment.

[0038] In order to realize the opening and closing action of the through hole opened on one side of the support frame 61 by the rotating mechanism 3, the rotating mechanism 3 is provided to include an electric turntable 32 fixed on the upper surface of the box body 1, the electric turntable 32 is electrically connected to the battery connected to the solar panel through a cable, a protective cover 31 is arranged on the periphery of the electric turntable 32, the lower end of the protective cover 31 is fixedly connected to the upper surface of the box body 1, the rotating part of the electric turntable 32 is fixedly connected to a rotating rod 33, the rotating rod 33 is rotatably connected to the upper end of the box body 1 through a bearing, and the rotating rod 33 The lower end is fixedly connected to a swivel 34, a connecting rod 35 is provided on the side of the swivel 34, and balls 36 are fixedly connected to both ends of the connecting rod 35. A ball groove matched with the ball 36 is opened on the side of the swivel 34, the ball 36 is in contact with the inner wall of the ball groove, and the contact part between the ball 36 and the connecting rod 35 is located on the outside of the ball groove, one fifth of the ball 36 is located outside the ball groove, and the surface of the other ball 36 is slidably connected to the baffle plate 37, and the plate body of the baffle plate 37 is rotatably connected to the frame surface of the support frame 61.

[0039] Specifically, the design of the entire rotating mechanism 3 makes the opening and closing operation of the through hole simple and convenient. The user can easily open and close the baffle 37 by controlling the start and stop of the electric turntable 32 without manual operation. There is no need to perform complicated manual operations, which improves the convenience and efficiency of using the baffle 37, thereby ensuring the sealing effect inside the box body 1 and preventing external impurities from entering the inside of the box body 1.

[0040] The lower end of the shielding plate 37 completely blocks the through hole opened in the frame of the supporting frame 61, and the surface of the shielding plate 37 and the surface of the supporting frame 61 are both coated with a sealing coating at the contact point; specifically, the lower end of the shielding plate 37 completely blocks the through hole of the supporting frame 61, and the sealing coating is applied at the surface contact point, which can effectively prevent air, moisture, dust and other foreign substances from entering the interior of the box body 1 through the through hole.

[0041] In order to realize the drying action of the evaporation mechanism 6 on the silica gel beads 65 that are full of water, the evaporation mechanism 6 is provided to also include a heat exchanger 62, one side of the heat exchanger 62 is fixedly connected to the inner wall of the box body 1, the inner top wall of the box body 1 is fixedly connected with a connecting rod 64, the lower end of the connecting rod 64 is fixedly connected with a ceramic block 63, the internal array of the ceramic block 63 is provided with a silica gel groove that is compatible with the silica gel beads 65, the ceramic block 63 is a cube, and the six faces of the ceramic block 63 are provided with an array of air holes, one end of each air hole passes through the silica gel groove arranged in the array and extends to the other side of the ceramic block 63, the diameter of each air hole is smaller than the diameter of the silica gel groove, the air holes are divided into two types with different diameters, among which one side of the air hole with a larger diameter is opposite to the through hole opened in the support frame 61.

[0042] Specifically, the ceramic material has no adverse effect on the silica gel beads 65 and will not react chemically with the silica gel beads 65, thereby ensuring the stable performance of the silica gel beads 65. The silica gel grooves that are compatible with the silica gel beads 65 are arranged in an array inside the ceramic block 63, and the air holes that are arranged in an array on the six surfaces enable the heat of the heated ceramic block 63 to be evenly transferred to each silica gel bead 65. The design of the air holes ensures the circulation of air so that evaporated moisture can be discharged smoothly. The design of the above structure, when used in areas with large temperature differences, can ensure that the water vapor generated by the temperature difference inside the box 1 is absorbed by the silica gel beads 65, thereby keeping the inside of the box 1 dry. At the same time, after the water absorption of the silica gel beads 65 is reduced, the moisture in the silica gel beads 65 is evaporated by heating the ceramic block 63 and is extracted by the exhaust fan 2, so that the silica gel beads 65 can be reused to avoid frequent replacement of the silica gel beads 65.

[0043] The lightning protection mechanism 5 includes a lightning rod 51, the lower end of the lightning rod 51 is threadedly connected to a fixing block 52, the fixing block 52 is made of mica, an insulating material, a threaded hole is opened in the fixing block 52, and a conductive gasket is arranged on the surface, the lower surface of the fixing block 52 is fixedly connected to the upper surface of the box 1, and a conductive strip 53 is arranged on one side of the fixing block 52, one end of the conductive strip 53 is inserted into the fixing block 52 and fixedly connected to the conductive gasket, and the surface array of the conductive strip 53 is fixedly connected to a stabilizing block 54, and one end of each stabilizing block 54 is respectively fixedly connected to the outer surface of the box 1; specifically, the lightning rod 51 can attract lightning and guide the lightning current to the ground, thereby protecting the box 1 and the internal equipment from lightning damage. The existence of the lightning rod 51 greatly reduces the risk of the box 1 being struck by lightning, and improves the safety and reliability of the equipment. The fixing block 52 is made of mica, an insulating material, which can effectively isolate the current conduction between the lightning rod 51 and the box 1, and prevent the lightning current from being conducted to other equipment or personnel through the box 1, causing secondary damage.

[0044] In order to realize the sealing mechanism 8 to prevent external rainwater from entering the interior of the box body 1, the sealing mechanism 8 is provided with a triangular pressure strip 81, and the vertical right-angled surface of the triangular pressure strip 81 is in contact with the surface of the box body 1. The upper end array of the box body 1 is provided with a mounting groove 82, and the bottom wall of each mounting groove 82 is provided with a spring 83. The lower end of each spring 83 is fixedly connected to the inner bottom wall of the mounting groove 82, and the upper end of each spring 83 is fixedly connected to a connecting block 84. The side surface of each connecting block 84 is slidably connected to the inner wall of the mounting groove 82, and one end of each connecting block 84 is fixedly connected to one side of the triangular pressure strip 81. Slide grooves are provided on both sides of the upper end of the box body 1, and the inner wall of each slide groove is slidably connected with a T-shaped latch 85. A bolt 86 is also provided on one side of each T-shaped latch 85. The surface of the T-shaped latch 85 is provided with a threaded hole compatible with the bolt 86, and one end of the bolt 86 contacts the inner wall of the slide groove.

[0045] Specifically, the triangular molding 81 can fit tightly against the upper end of the cabinet door of the box body 1 to form an effective barrier to prevent external rainwater from entering the interior of the box body 1. During the installation process, the position of the triangular molding 81 can be adjusted according to actual conditions to ensure its fit with the surface of the box body 1. At the same time, the setting of the bolt 86 can further fix the T-shaped pin 85 to prevent it from loosening during use.

[0046] A rubber gasket is provided on the horizontal right-angled surface of the triangular pressure strip 81, and grooves compatible with the T-shaped pin 85 are opened at both ends of the triangular pressure strip 81; specifically, the rubber gasket is provided on the horizontal right-angled surface of the triangular pressure strip 81, which can further enhance the sealing performance of the sealing mechanism. The rubber gasket has good elasticity and flexibility, can fit tightly to the surface of the box body 1, fill the tiny gap between the triangular pressure strip 81 and the box body 1, and effectively prevent the intrusion of external substances such as rainwater and dust.

[0047] An exhaust port is provided on the box body 1 at the position of the exhaust fan 2, and a magnetic plate which is rotatably connected to the outer side surface of the box body 1 and matches the exhaust port. The diameter of the magnetic plate is larger than the diameter of the exhaust port, and the magnetic attraction force between the magnetic plate and the box body 1 is smaller than the suction force generated by the exhaust fan 2; specifically, when the exhaust fan 2 is working, since the magnetic attraction force between the magnetic plate and the box body 1 is smaller than the suction force generated by the exhaust fan, the suction force generated by the exhaust fan 2 will overcome the magnetic attraction force to suck the magnetic plate open, thereby opening the exhaust port and realizing air circulation inside the box body 1; and when the exhaust fan 2 stops working, the magnetic plate will automatically close the exhaust port under the action of the magnetic attraction force to prevent external dust, debris, etc. from entering the interior of the box body; this design can flexibly control the ventilation state of the box body 1, turn on or off the exhaust fan 2 according to actual needs, and realize effective adjustment of the internal environment of the box body 1.

[0048] A humidity sensor is also provided inside the box 1; specifically, the humidity sensor can monitor the humidity condition inside the box 1 in real time.

[0049] Reference Figure 1-Figure 11 , a method for using a rainproof communication optical cable junction box, the specific operation steps are as follows:

[0050] Step 1, the cabinet door of the cabinet 1 is kept closed, and the temperature sensor and the humidity sensor are opened at the same time to monitor the temperature and humidity in the cabinet 1. The silica gel beads 65 continue to dehumidify the interior of the cabinet 1. When the temperature difference between the inside and outside of the cabinet 1 is too large, causing water vapor to be generated inside the cabinet 1 and the humidity exceeds the threshold, the humidity sensor transmits a signal to the control center, and the control center starts the exhaust fan 2 to start working. The air at the exhaust port is reduced and the pressure drops. The exhaust port adsorbs the magnetic plate, and the magnetic plate opens. The exhaust port is connected to the interior of the cabinet 1. The baffle plate 37 drives the connecting rod 35 to pull and rotate under the action of the electric turntable 32, and the through hole is opened. The air in the cabinet 1 starts to flow, and the air mixed with water vapor is discharged. The discharged water vapor is partially absorbed by the silica gel beads 65, and part is discharged outside the cabinet 1.

[0051] Step 2. When the humidity inside the box 1 gradually rises and does not decrease, the ceramic block 63 starts to heat up and the heat exchanger 62 is turned on at the same time. The ceramic block 63 heats the silica gel beads 65 arranged inside it to evaporate the absorbed moisture. At this time, the exhaust fan 2 works at the same time, the evaporated moisture is extracted, the baffle plate 37 opens the through hole, and the heat exchanger 62 dissipates the excessive temperature through the inner wall of the box 1 to the outside of the box 1.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
