Abstract
The invention discloses an outdoor electric appliance distribution box waterproof system. A power distribution cabinet housing is provided with a water pressure monitoring assembly, and the water pressure monitoring assembly comprises a water level gas room. A pressure gauge comprises a film sealing an upper end of a connection flexible pipe, and a pressure sensor which is arranged to be close to the film. The water level gas room, the connection flexible pipe and the film form a semi-closed gas channel with the lower part of the water level gas room being opened. If the bottom water level of the power distribution cabinet housing exceeds the lower opening of the water level gas room, the semi-closed gas channel forms a full-closed gas channel, and the air in the gas channel is compressed along with the rise of the water level. The compressed air pushes the film, so the pressure sensor senses a pressure signal. A central processing unit transmits an opening signal to a pump body according to a detected unit pressure signal, and the pump body starts to drain away water, thereby guaranteeing that the interior of a power distribution cabinet remains dry, preventing water immersion from damaging a power distributor, prolonging the service life of the power distributor, and reducing the maintenance cost. Meanwhile, the system avoids the inconvenience to the life of persons and production.
