DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figures 1 to 4 As shown, the embodiment of the utility model provides a distribution box with moisture-proof and dehumidification functions, including a box body 1, a support column 2 is fixedly connected to the bottom of the inner surface of the box body 1, a mounting frame 3 is fixedly connected to the top of the support column 2, an electrical component terminal board 4 is fixedly connected to the inside of the mounting frame 3, a drying mechanism 6 is fixedly connected to the inside of the box body 1, a dehumidification mechanism 7 is fixedly connected to the outer surface of the box body 1, the dehumidification mechanism 7 includes an exhaust duct 71, the outer surface of the exhaust duct 71 is fixedly connected to the inside of the box body 1, and a box cover 5 is rotatably connected to the top of the box body 1. By setting the drying mechanism 6, hot air can be generated to dry the electrical components on the electrical component terminal board 4, thereby improving the insulation of the internal circuit of the distribution box and reducing the adverse effects of low insulation on power-on when power is turned on. By setting the dehumidification mechanism 7, external moisture can be prevented from entering the inside of the box body 1 from the exhaust duct 71, so that the exhaust duct 71 can be closed in time after drying, thereby reducing the influence of external moisture on the internal circuit of the distribution box and improving the safety of the use of the distribution box.

[0022] On the basis of the above embodiment, the drying mechanism 6 includes a fan 61, the bottom of the fan 61 is fixedly connected to the bottom of the inner surface of the box body 1, the outer surface of the fan 61 is fixedly connected to an air suction pipe 62, the air suction pipe 62 runs through the box body 1 and extends outward, and the end of the air suction pipe 62 is rotatably connected to a switch cover 68, which can prevent external moisture from entering the interior of the box body 1 from the air suction pipe 62, thereby reducing the influence of external moisture on the internal circuit of the distribution box, the output end of the fan 61 is fixedly connected to an air outlet pipe 63, the output end of the air outlet pipe 63 is fixedly connected to a wind cover 64, and the air outlet pipe 6 A heating cylinder 65 is fixedly connected to the middle of the inner part of 3. When in use or stopped, the staff manually opens the switch cover 68, starts the fan 61 to allow the external cold air to enter from the air suction pipe 62 and blow out from the air outlet pipe 63. The airflow enters the air outlet pipe 63 and passes through the heating cylinder 65, so that the cold air becomes hot air in the heating cylinder 65, enters the part of the air outlet pipe 63 above it, and is finally led out by the wind cover 64. The wind cover 64 faces the electrical component terminal board 4, so that the hot air can be used to dry the electrical component terminal board 4 more fully, thereby improving the insulation of the electrical components inside the distribution box.

[0023] As a further preference of this embodiment, a heating wire 66 and a temperature controller 67 are fixedly connected to the inner surface of the heating tube 65, and the temperature controller 67 is electrically connected to the heating wire 66. By setting the temperature controller 67, the heating temperature of the heating wire 66 can be controlled so that the temperature will not be too high to affect the operation of the electrical components on the electrical component terminal board 4.

[0024] Specifically, the dehumidification mechanism 7 also includes a mounting block 72, which is fixedly connected to the inner surface of the exhaust pipe 71. The inner surface of the mounting block 72 is provided with a vent 73 and a slide groove 74. The inner sliding connection of the slide groove 74 is connected to a limit rod 75. The outer surface of the limit rod 75 passes through the slide groove 74 and extends outward. The output end of the limit rod 75 is fixedly connected to a sealing block 76. The airflow inside the box body 1 passes through the exhaust pipe 71. Under the thrust of the airflow, the sealing block 76 is separated from the vent 73 in the mounting block 72. The limit rod 75 slides outward along the inner surface of the slide groove 74. When the spring 77 is compressed and accumulated, the airflow passes through the gap between the vent 73 and the sealing block 76, and is finally discharged to the outside from the output end of the exhaust pipe 71.

[0025] In addition, the outer surface of the sealing block 76 matches the inner surface of the vent hole 73, and the outer surface of the limiting rod 75 is sleeved with a spring 77. The end of the spring 77 is fixedly connected to the inner surface of the slide groove 74, and the output end of the spring 77 is fixedly connected to the outer surface of the limiting rod 75. After the drying mechanism 6 stops being used, the elastic force of the spring 77 causes the limiting rod 75 to slide in the opposite direction along the inner surface of the slide groove 74, so that the sealing block 76 returns to the inside of the vent hole 73 and blocks the vent hole 73 again, thereby preventing external moisture from entering the interior of the box body 1 from the exhaust pipe 71 and affecting the internal circuit of the distribution box.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
