Detailed Description

The embodiment of the utility model provides a marine pollution sampling device, as shown in fig. 1-4, including having collection box 1, stay cord 3, floating seat 4, aqueduct 6, locating piece 15 and the sampling mechanism who holds chamber 11, collection box 1, stay cord 3, locating piece 15 link to each other in proper order, and locating piece 15 can sink in the seabed also can fix in the seabed. The side surface of the collection box 1 is provided with a collection port 5 communicated with the containing cavity 11, the floating seats 4 are arranged at two sides of the collection box 1, and the floating lines of the floating seats are level with the central line of the collection port 5.

The floating seat 4 is set to be level with the central line of the acquisition port 5, so that half of the acquisition port 5 is positioned below the sea surface and half of the acquisition port is positioned on the sea surface, the seawater entering the accommodating cavity 11 is the water on the sea surface, and the detected structure is more accurate.

The collection box 1 is in an isosceles trapezoid shape, and the top edge of the collection box faces downwards. The collection tank 1 is boat-like and more stable on the water surface.

The bottom of the collection box 1 is provided with a stabilizing seat 2. The weight of the stabilizing seat 2 is consistent with that of the collection box 1, so that the gravity center of the collection box 1 is vertically downward and is more stable.

The water guide pipe 6 is vertically arranged on the collection box 1 and is connected with the containing cavity 11, the water guide pipe 6 is used for guiding out water in the containing cavity 11 of the collection box 1, the water guide pipe 6 is located above the water surface, and the sampling mechanism can take out the water in the containing cavity 11 through the water guide pipe 6.
