The invention discloses a live fish transportation temporary preservation device facilitating mobile dumping. The device structurally comprises a
handle, four ventilation pipes, a protection cover anda transportation storage box; the protection cover is inlaid in the top of the transportation storage box through buckling, the
handle is locked to the middle of the top of the protection cover, thefour ventilation pipes are integrally arranged on the four sides of the top of the protection cover, and the storage storage box comprises an inner container capable of achieving dumping, an inner base, an outer protection shell and a
storage tank; when the device is used, by means of the shell capable of rising and a base internally provided with mobile wheels, the device can automatically trigger a
buoyancy device when live fishes exist, when moving is needed, switching of device moving can be conducted manually, and moving of the device after live fish loading is facilitated; by arranging the inner container capable of achieving dumping matched with a
speed limit and bottom rail device, when the device is used, convenient and labor-saving dumping can be conducted, the influence caused by gravity can be better avoided, unloading of the live fishes and the like is facilitated, time and labor are better saved, and use is facilitated.
