DEVICE FOR SAMPLING OF MINERAL PARTICLES FROM VARIOUS HORIZONS IN BOTTOM SEA LAYER Russian patent published in 2017 - IPC G01N1/16 

FIELD: measuring equipment.

SUBSTANCE: device contains a frame 1, on which tubular samplers are fixed. The frame 1 is made in the form of cargoes fixed on the sea bottom in the zone of intense excitement and collapse of waves of a solid pyramid made of a bar, mainly triangular. Inside the sampler assembly is rigidly fixed, made in the form of a combined bundle of vertically arranged tubes 4 of the same cross-section. At the lower ends of the pipes 4, the suction heads located in the corresponding prescribed sea horizons are fixed in the form of hollow rigid horizontal discs 5 of the same diameter that are located on the axis of the combined bundle of tubes and have the same predetermined size corresponding to the size of the pipe cross-section, the height size of their cavities. The diameter of the discs 5 exceeds the cross-sectional dimension of the combined tube bundle. The lateral surface of each disc 5 is made in the form of a grid with a given throughput and externally is provided with a filter 6, preferably made in the form of a fine mesh network loosely adjacent to the side surface of the disc. Each disc 5 is fixed to the corresponding pipe 4 so that its sealing opening communicates with the disc cavity through an opening in its upper base. In the upper and lower bases of each disc 5, in addition to the lower disc, one or more pairs of coaxial holes are made, through which other tubes of the combined beam are passed and in which they are rigidly fixed to the sealing. The space between the discs is occupied by coaxially aligned cylindrical fairings 7 of the same predetermined external diameter. Advantageously, the outer diameter of the fairings 7 is greater than the diameter of the discs 5. The outlet of each pipe 4 is connected to the corresponding inlet of the multi-position tap 9, provided with a drive 8, the outlet of which is connected by a hose 10 to the pump 11, the outlet pipe of which is connected to the coast station for receiving and processing the samples. The pump 11 is fixed to one of the faces of the frame 1 and is connected to the shore remote power supply and control unit, to which the multi-position crane drive 9 is connected.

EFFECT: increasing the reliability of determining the qualitative and quantitative composition of the particle samples in the bottom layer of the offshore sea zone in real time, and its vertical distribution, which is necessary for estimating the fluxes of particles affecting the variation of the shoreline and the bottom relief.
