the working principle of the power distribution cabinet is as follows; when the rain day works, rainwater enters the sliding cylinder, the floating block drives the conductive block to slide upwards under the buoyancy effect of the rainwater, the conductive block contacts with the conductive sheet, so that the solar panel and the motor form a closed circuit, the second switch is closed, the circuit between the first switch and the thermoelectric generation tube is always disconnected in the rain day, at the moment, the motor rotates anticlockwise to drive the threaded rod to rotate anticlockwise to drive the second movable plate to move upwards until the first movable plate contacts with the partition plate, the radiating holes on the partition plate are blocked, and the rainwater is prevented from penetrating above the partition plate; in addition, when the rainwater is less in the early stage of light rain or heavy rain, the floating blocks move upwards under the buoyancy of a small amount of rainwater, and when the conductive blocks are not contacted with the conductive blocks, the first sponge cushion and the second sponge cushion adsorb the rainwater which enters the cabinet body and is positioned at the lower side of the partition plate, so that the power distribution cabinet is prevented from being affected with damp by a small amount of rainwater;
when the power distribution cabinet works normally, the second movable plate is positioned at the symmetrical plane position of the lower sides of the partition plate and the cabinet body, a gap is reserved between the first movable plate and the partition plate, meanwhile, the lower side of the second sponge cushion is in contact with the lower side of the cabinet body, the second sponge cushion is not compressed, heat generated by the work of the power distribution cabinet is carried by air in the cabinet body, and the heat is discharged to the outside after sequentially passing through the partition plate, the first movable plate, the first sponge cushion, the second movable plate, the second sponge cushion and the lower side of the cabinet body, so that the heat dissipation of the power distribution cabinet is realized;
when external temperature is higher than the internal temperature of cabinet, and external when no raining, the second switch is opened, external and the internal temperature difference of cabinet makes the thermoelectric generation pipe produce the electric energy simultaneously and triggers first switch and open, the circuit at solar panel, motor and first switch place forms closed circuit, solar panel supplies power to the motor, make the motor rotate clockwise, drive threaded rod rotate clockwise, drive second fly leaf and move down, first fly leaf and baffle separation, the second foam-rubber cushion is hugged closely in cabinet downside simultaneously, with the louvre shutoff of cabinet downside, the density grow after the second foam-rubber cushion is compressed tightly, the gas permeability reduces, reduce the louvre gas permeability of cabinet downside, reduce the air exchange rate of cabinet and external environment, reduce the internal volume of external high temperature gas entering into the cabinet, reduce the influence of external high temperature to cabinet internal gas.
2. The self-moving type anti-seepage outdoor power distribution cabinet according to claim 1, wherein the side edge of the first movable plate is an inclined surface, a limiting ring is arranged on the second movable plate, the inner side of the limiting ring is an inclined surface, and the first movable plate is limited through the cooperation of the inclined surface of the side surface of the first movable plate and the inclined surface of the inner side of the limiting ring.
3. The self-moving type anti-seepage outdoor power distribution cabinet according to claim 1, wherein four supporting blocks are arranged on the upper side of the partition board, the power distribution cabinet is installed on the supporting blocks, gaps are reserved between the power distribution cabinet and the partition board through the supporting blocks, and heat generated by the power distribution cabinet is conveniently dissipated from radiating holes in the partition board.
4. The self-moving type anti-seepage outdoor power distribution cabinet according to claim 1, wherein an output shaft of the motor penetrates through a partition plate part to be subjected to waterproof sealing treatment through a sleeve sealing gasket.
5. The self-moving type anti-seepage outdoor power distribution cabinet according to claim 1, wherein the diameter of the radiating holes on the partition plate is smaller than the distance between the adjacent radiating holes of the first movable plate, so that the radiating holes on the partition plate are completely blocked after the first movable plate contacts with the partition plate.
