The device for assessing the contamination of bottom sediments of the aquatic environment with oil and oil products contains a housing 1 made in the form of a surface water craft. Inside the body 1 there is a sample storage tank 2.

An air supply device is connected to the hull 1, made in the form of two structures folding along helical lines in a vertical plane, located symmetrically along the sides of the surface watercraft 1.

A device for assessing the contamination of bottom sediments of the aquatic environment with oil and oil products works as follows.

The technology of work includes two cycles: sampling at a certain length of a section of a reservoir; disposal after sample evaluation for disposal and preparation for new sampling.

The surface watercraft 1 is placed in a reservoir, where it is necessary to take sediment samples to determine the quantitative indicators of the fractional composition, including oil or oil products.

Cycle 1. The operation of only one air supply device is considered. The electric hoist 14 is turned on, and the cable 13 is fed down, lowering the device for supplying air to the working position, the receiving box 11 with wheels 12 is in contact with the bottom of the reservoir (dashed lines in Fig.1). Sample storage tank 2 is empty, drain pump 15 is turned off, valve 16 is closed. At the same time, the pump 20 is turned on and the taps 19 and 25 open. Water from the reservoir passes through the suction pipe 21 through the pump 20, the ejector 17, into which atmospheric air is sucked in through the tube 18 and the water-air mixture enters the flexible pipes 6 and then exits at high speed through the conical nozzles 22 and erodes the soil sediment - a slurry is formed, which, through a flexible pipe 24 connected to the branch pipe 23, enters through an open valve 25 into the sample storage tank 2. The flotation process occurs in the sample storage tank 2: light oil fractions float and accumulate on a surface. Quantitative indicators of the fractional composition are estimated and recorded for the considered section of the reservoir.

Cycle 2. The pump 20 is turned off, the valve 25 is closed. The valve 16 opens, the pump 15 is turned on and the sample from the sample storage tank 2, after evaluation, is removed for disposal. Sample container 2 is empty and ready to receive new samples.

After completion of work, the air supply device is brought into the transport position. The electric hoist 14 is turned on and the cable 13 moves up in the holes 5. At the same time, the cables 8 in the holes 7, together with the balls - limiters 9 and flexible pipes 6 in the holes 4 of the round plates 3, are folded along helical lines into a block in Fig.1. The bracket 10 fastens and holds the air supply device on the housing 1, and the receiving box 11 is fixed to the housing 1 with a cable (not shown in Fig. 1).

Compared with the prototype, the proposed device for assessing the contamination of bottom sediments of the aquatic environment with oil and oil products will allow continuous sampling and evaluation of samples on the same boat.
