Zusammenfassung:	The utility model discloses a rapid cooling device for an excavation cabin. The problem that in the prior art, the cooling speed of the excavation cabin is low is solved. The device comprises a cooling device, an air cooler and a refrigerating device, wherein the cooling device is arranged in a cabin adjacent to an excavation cabin; a liquid outlet of the refrigerating device is connected with thecooling device and the air cooler through a freezing water inlet pipeline, and the cooling device and the air cooler are connected with a liquid inlet of the refrigerating device through a freezing water return pipeline. The cooling device is additionally arranged in the transition cabin or the air cushion cabin, the air flowing speed of the excavation cabin is increased, heat exchange is directly carried out on air, and therefore the cooling time of the excavation cabin is shortened. By shortening the cooling time of the excavation cabin, the under-pressure cabin entering operation preparation time is shortened, the
