A salinity automatic control device for aquaculture

The utility model relates to a salinity automatic control device for aquaculture, breed groove, its characterized in that including at least one monomer: each monomer is bred to be provided with on groove and is supplied the high salinity sea water to get into the groove was bred to the monomer first water pipe and sea water solenoid valve, and correspondingly, each monomer is bred to be provided with on groove and is supplied fresh water to get into the groove was bred to the monomer second water pipe and fresh water solenoid valve, and each monomer breed inslot is provided with the salinity sensor, and salinity control assembly and control system compare with prior art, the utility model has the advantages of salinity control assembly has been arranged through breeding the inslot in the difference to controlling with the salinity of breeding the inslot to the difference more accurately through control system, thereby realizing carrying out the control of salinity to the built -in breed groove that has different growth cycle's three wart swimming crab soft crabs, the different salinity of breeding inslots of assurance that can be better are in equitable within range.
