Liquid cargo loading and unloading area low-temperature protection structure of bulged deck ship and loading and unloading area structure

The invention provides a liquid cargo loading and unloading area low-temperature protection structure of a bulged deck ship and a loading and unloading area structure. The low-temperature protection structure comprises a slope protection plate, a liquid collecting tray, a discharge pipe, a broadside protection plate and a shielding plate. The slope protection plate comprises an inclined section and a smooth section which are integrated, the inclined section is installed on the surface of the high-inclination deck, and the smooth section extends to the position above the smooth deck. The liquid collecting tray is arranged on the smooth deck and partially located below the smooth section. And the liquid collecting tray is provided with a discharge hole and is connected with a discharge pipe below. The broadside protection plate is arranged on the smooth deck, located on the side, away from the slope protection plate, of the liquid collection tray and extends to a ship side. The shielding plate is arranged betwe
