The invention relates to a stable supporting structure of a long shafting for a seawater source heat pump. The supporting structure comprises an upper shaft sealing location supporting structure body, a middle supporting structure body and a lower supporting body which are connected in sequence and connected with an upper shaft, a middle shaft and a lower shaft correspondingly. An upper supporting shaft lining is connected with the upper shaft. The supporting structure further comprises at least one middle supporting pipe and a lower supporting pipe, wherein middle supporting shaft linings connected to the middle shaft are arranged on the upper portion and the lower portion of the middle supporting pipe correspondingly; the lower shaft is sleeved with the lower supporting pipe in a connected mode; the lower shaft is connected with a lower supporting shaft lining; and at least one supporting board is arranged in the middle or on the lower portion within the whole length range of a pump supporting pipe.
