Rotatable cold air cooling device in container

The utility model discloses a rotatable cold air cooling device in a container, which comprises a base, a telescopic rod and a cold air releaser, rolling support legs are arranged on the base, a rolling inner pipe and a rolling outer pipe are arranged on the rolling support legs, and the rolling outer pipe and the rolling outer pipe are connected through a bearing so as to realize the rotating connection of the rolling outer pipe and the rolling outer pipe. The rolling outer pipe rotates along with the pressure container, so that the rolling device is always placed at the lowest point of the pressure container, and the problem that the air pipe cannot be placed due to the fact that the air pipe is easily influenced by rotation of the pressure container during ventilation can be solved. 本实用新型公开了一种容器内可转动冷气降温装置，包括底座、伸缩杆及冷气释放器，底座上设有滚动支脚，滚动支角上设有滚动内管和滚动外管，其中滚动外管和滚动外管之间通过轴承连接，以实现两者的转动连接，当压力容器转动时，滚动外管随之转动，使本实用新型始终安放于压力容器的最低点，能解决气管通气时，容易受压力容器转动的影响，而造成气管无法安放的问题。
