Detailed ways

An embodiment of the present utility model provides a marine pollution sampling device, as shown in Figures 1-4, comprising a collection box 1 with a cavity 11, a pulling rope 3, a floating seat 4, a water conduit 6, a positioning block 15 and a sampling mechanism , the collection box 1, the pulling rope 3, and the positioning block 15 are connected in sequence, and the positioning block 15 can be sunk on the seabed or fixed on the seabed. The side of the collection box 1 is provided with a collection port 5 which communicates with the cavity 11 .

Set the floating base 4 so that the floating line is the same as the center line of the collection port 5, so that half of the collection port 5 is located below the sea surface and half is located on the sea surface, so that the seawater entering the cavity 11 is all the water on the sea surface, and the detected structure is more accurate. .

The outer shape of the collecting box 1 is an isosceles trapezoid with the top side facing down. The collection box 1 resembles a boat and is more stable on the water.

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

The water conduit 6 is vertically arranged on the collection box 1 and is connected to the cavity 11. The water conduit 6 is used to lead out the water in the cavity 11 of the collection box 1.
