The using method of the power distribution cabinet specifically comprises the following steps:

when the outside rains, rainwater is collected through the rainwater collection part 2, the rainwater in the rainwater collection part 2 penetrates through the permeable geotextile 202 and flows into the water storage tank 3 through the sewer pipe 203 to be stored, then when the temperature sensor 7 senses that the temperature in the cabinet body 1 is too high in hot weather, a signal with the too high temperature is transmitted to the control box 10, then the circulating water pump 406 is started through the control box 10, the circulating water pump 406 conveys the rainwater stored in the water storage tank 3 to the inside of the first frame-shaped pipe 401 through the water inlet pipe 404, then the rainwater flows into the four heat absorption pipes 403, heat absorbed by the outer walls of the four heat absorption pipes 403 is brought into the second frame-shaped pipe 402, then the rainwater flows back to the inside of the water storage tank 3 through the water return pipe 405, and then heat dissipation is carried out through the outer wall of the water storage tank 3;

when the inside water yield of water storage box 3 is less, the inside surface of water storage box 3 will reduce, float 8 will also follow the downstream under the buoyancy of water, then drive connection frame 802 downstream through slip branch 801, thereby make and press a piece 804 and follow the downstream, then when pressing a piece 804 bottom surface and waterproof film 903 upper surface in close contact with, the button that makes on the gate switch 902 through the pressure that presses a piece 804 obtains pressing the operation, thereby make control box 10 and temperature sensor 7 all be in the outage state.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
