After desalination is complete, the remaining air inside the desalination cylinder not only prevents fresh water leakage but also provides a sealing effect, simplifying the device and eliminating the need for additional sealing structures.

This invention provides a split-type explosion-proof robot control cabinet based on an external air source, relating to the fields of industrial automation and explosion-proof safety technology. It includes an explosion-proof cabinet and a positive-pressure cabinet, connected via a docking interface. An external air source is input into the positive-pressure cabinet to form a positive-pressure airflow, dissipating heat from the cabinet and maintaining an internal pressure higher than the external environment. The explosion-proof cabinet is a sealed cavity. After the positive-pressure airflow exits from the positive-pressure cabinet, it flows over the outer surface of the explosion-proof cabinet, further dissipating heat. This invention achieves dual explosion-proof protection by independently designing and collaboratively operating the explosion-proof cabinet and the positive-pressure cabinet. The positive-pressure cabinet prevents the infiltration of external flammable gases through dynamic pressure control. The two modules achieve physical isolation and functional linkage through a quick-connect interface, balancing explosion-proof performance with modular maintenance requirements.
