A draining device is disposed within a drain port, which is defined by an upper end of a drain pipe embedded in the ground at an elevation below the ground surface. The draining device includes a tubular base member which has an open upper end, a closed lower end, a bottom wall, and a peripheral wall that extends between the upper and lower ends and that is formed with a plurality of drain openings. A water guiding tube is attached within the base member, and extends into the peripheral wall of the base member. The drain openings of the base member are located around the water guiding tube at an elevation above a lower end of the water guiding tube. The water guiding tube has open upper and lower ends, and is capable of guiding water from the upper end of the base member to the bottom wall of the base member. When water accumulates in a lower end portion of the base member, the water surface thereof is above the lower end of the water guiding tube so as to isolate air in the water guiding tube from air in the drain pipe, thereby preventing insects in the drain pipe from accessing the water guiding tube.
