Sample collection apparatus

A sample collection apparatus comprising:

• a frame section having a lower frame seated on a seabed surface and an opening provided at one side thereof, an upper frame connected to the lower frame and having an operation hole formed in a center thereof, and an operation space formed between the upper and lower frames;
• a vertical operation section including:
• a vertical operation member provided through the operation hole to be vertically movable, and including weights provided on left and right sides of a lower portion thereof, and a trigger device provided at an upper end thereof, to be connected to a lifting cable;
• and a box-mounting unit provided at a lower end of the vertical operation member located in the operation space, and configured such that a sample collection box having opened upper and lower portions is mounted thereon or detached therefrom;
• and
• a rotary operation section having a pair of rotary members coupled to both side surfaces of the box-mounting unit by rotary shafts, wherein one ends of the rotary members are connected to the trigger device by pulling cables and an arc-shaped box opening/closing member is provided at remaining ends of the rotary members, and the rotary operation section is configured such that, after the frame section is seated on the seabed surface, the trigger device is operated, and the vertical operation member descends such that the sample collection box mounted on the box-mounting unit digs into the seabed surface and the rotary members are rotated about the rotary shafts by pulling of the pulling cable such that the box opening/closing member closes the opened lower portion of the sample collection box so as to prevent a sample from flowing out.
