This utility model relates to the field of communication
engineering cabinet technology, and more particularly to a weatherproof outer shell for outdoor communication
engineering equipment, including a cabinet; it also includes a base, an
airbag, a waterproof
air pump, a
water level sensor, a PLC controller, a sliding frame, a screw, a slider, a drive frame, an annular scraper, a sliding sleeve, a sliding rod, and a limiting ring. The bottom of the cabinet is provided with a base, and the top of the inner surface of the base is provided with an
airbag. The top of the right side of the inner surface of the base is connected to the waterproof
air pump, and the output end of the waterproof
air pump is connected to the
airbag. The
water level sensor is provided at the top of the right side of the inner surface of the base corresponding to the position of the waterproof air pump. This utility model, by setting up an airbag, when the
water level sensor detects that the water level exceeds the safety threshold, the PLC controller activates the waterproof air pump to inject gas into the airbag. The
buoyancy of the airbag in the water pushes the cabinet, causing the cabinet to move upward along the sliding rod, thereby raising the cabinet and preventing
water immersion.
