Abstract: The present invention relates to a press-type water sampling device, and to a press-type water sampling device comprising: a water sampling bottle having opened upper and lower parts; and a bumper support, which has a top cap and a bottom cap for blocking the opened upper and lower parts of the water sampling bottle, is formed into a frame having a shape that encompasses the water sampling bottle, and enables the water sampling bottle to be vertically moveable. The present invention enables the water sampling bottle to be separated from the bumper support so as to prevent breakage and water leakage of the water sampling bottle and facilitate cleaning of the water sampling bottle, smoothly collects water at the upper and lower parts of the water sampling bottle since the water sampling bottle is formed at predetermined gaps from the top cap and the bottom cap at the center portion of the bumper support, and can improve accuracy and reliability of a sample water analysis since the water sampling device is formed in an integrated sliding structure, in which the top cap fixed to the bumper support moves down by a messenger moving down when the water sampling device reaches a water depth of a target location and the water sampling bottle is sealed by the top cap and the bottom cap.
