Workstation for seabed long-term scientific investigation

The utility model relates to ocean engineering, in particular to a workstation for seabed long-term scientific investigation. The utility model aims to provide the workstation for long-term scientific research on the seabed, which is simple in structure, good in stability and long in working time. The workstation comprises a main control cabin and a plurality of functional cabins, the main control cabin and the functional cabins are connected through a corridor, a plurality of module expansion bases are arranged on the functional cabins, a plurality of tidal current generators are arranged on the side faces of the main control cabin and the functional cabins, an inner pipeline channel and an outer pipeline channel are arranged on the corridor, and the inner pipeline channel is communicated with the outer pipeline channel. The two ends of the inner pipeline channel and the two ends of the outer pipeline channel are connected with the main control cabin and the function cabin respectively. Each functional cabin
