[0019] Beneficial effects of the present invention:

[0020] (1) When the humidity outside is too high, the heat dissipation holes on the branch box are closed, and then the air with high humidity in the box is blown into the dehumidification box by a fan to keep the air in the box dry. At the same time, the heat is dissipated in the box through the circulating heat dissipation mechanism, and the outside moisture is prevented from entering, thereby effectively removing the moisture in the branch box and greatly reducing the impact of moisture on the cables in the branch box.

[0021] (2) When the humidity in the air decreases, the silica gel desiccant in the dehumidification box is automatically dried by the self-drying mechanism, so that the silica gel desiccant in the dehumidification box is fully dried, which is convenient for the next use of the silica gel desiccant and realizes the reuse of the silica gel desiccant.

[0022] (3) During the installation process, the first cooling pipe and the second cooling pipe are buried in the ground, and then water is pumped into the first cooling elbow and the second cooling elbow through a water pump. The heat in the box is then conducted out through heat conduction, and the water that absorbs heat in the first cooling pipe automatically overflows. At the same time, the second cooling pipe replenishes cooling water into the first cooling pipe through the principle of a communicating vessel, thereby improving the heat dissipation effect in the box and reducing the influence of temperature on the cables in the branch box during dehumidification and preventing moisture from entering.

[0023] (4) By inserting the mounting block on the box body into the fixing column and threading the fixing block onto the top of the fixing column, and then fixing the fixing plate on the ground, when water accumulates at the installation location of the box body, the floating plate is used to isolate the box body from absorbing water. When the accumulated water reaches a certain level, the floating plate drives the box body to move upward under the action of buoyancy, thereby realizing the automatic waterproofing of the box body.
