PURPOSE: A sequential water sampling apparatus is provided to conveniently pick water sample at specific intervals, thereby analyzing and evaluating the water quality pattern. CONSTITUTION: A sequential water sampling apparatus includes a frame (10), a timer (20), multiple sampling bottles (30), an opening and closing unit (40), and an eccentric protrusion (50). The timer has a rotating shaft (22). The multiple sampling bottles are arranged in the radial direction based on the rotating shaft of the timer. The opening and closing unit has a central portion which is coupled by a pin (42) at the frame so as to open and close each of inlets of multiple sampling bottles, includes lids (44) which open and close the inlets at one end of the opening and closing unit, and maintains that the lids, which closes the inlets by using an elastic member, closely contact with the inlets. The eccentric protrusion is provided on the rotating shaft, contacts the opening and closing unit which is coupled to the sampling bottles arranged according to the rotation of the rotating shaft in the radial direction, and successively opens the lids that block each of the inlets of sampling bottles. |
