Mobile direct-current deicing horizontal access device

The invention discloses a mobile direct-current deicing horizontal access device. The mobile direct-current deicing horizontal access device comprises an electric pole fixedly connected onto the ground, a post insulator I, an isolated insulator, a direct-current bus, a post insulator II, an alternating-current bus and fixed contacts and moving contacts which are matched with each other, wherein the direct-current bus and the alternating-current bus are vertically fixedly connected onto the electric pole through the horizontal post insulator I and the horizontal post insulator II respectively;the direct-current bus and the alternating-current bus are connected through the isolated insulator; the fixed contacts are mounted on the direct-current bus and the alternating-current bus respectively; the moving contacts corresponding to the fixed contacts are mounted on a vehicle-mounted direct-current deicing device; the alternating-current bus is switched in an alternating-current power supply through an alternating
