DEVICE FOR SAMPLING MINERAL SUSPENDED SOLID MATERIALS FROM VARIOUS HORIZONS IN A SEABED LAYER IN ZONES OF INTENSIVE RISE AND FALL OF WAVES AND WAVE BREAKING Russian patent published in 2018 - IPC G01N1/16 G01N15/06 

FIELD: physics.

SUBSTANCE: invention can be used for oceanological and engineering and hydrogeological studies in a seabed layer in zones of intensive rise and fall of waves and wave breaking. Device comprises bearing frame 1 in the form of a pyramid made of a bar and fixed by distributed load 2 to the seabed, inside which sampling probe 3 in the form of a hose is vertically installed. Outlet end of sampling probe 3 is connected to pump 10 fixed to one of supports of coil 8, the outlet pipe of which is connected by hose 11 for supplying suspended solid materials to the shore station for receiving and processing the samples. Pump 10 is connected to a shore remote power and control unit. At the inlet of sampling probe 3, coaxially with its inlet hole, closed cylindrical hollow suction head 5 is rigidly sealed, lateral surface of the suction head is formed with intake holes 6 and is protected from the outside by filter 7. Inlet of sampling probe 3 is located in vertical guide 4, which is rigidly fixed inside bearing frame 1 and is made in the form of rigidly interconnected bars of cross section. Inlet of sampling probe 3 is mounted in guide 4 with the possibility of vertical sliding of suction head 5 in it. Outer diameter of suction head 5 exceeds the outer diameter of sampling probe 3. Holes on the lateral surface of head 5 have the same shape and the same geometric dimensions, are made in one plane perpendicular to its axis, and are located radially with respect to this axis and symmetrically with respect to each other. Filter 7 is made in the form of a sleeving of a fine mesh, self-cleaning from seaweed under the influence of waves and not tightly adjacent to the outer lateral surface of vertical guide 4. In the upper part of bearing frame 1, coil 8, provided with motor 9, is rigidly fixed, on the working surface of the coil the predetermined part of sampling probe 3 is laid. Working surface of coil 8 is made in the form of a screw guide. Motor 9 of coil 8 is connected to a shore remote power and control unit.

EFFECT: increasing the accuracy and reliability of determining the qualitative and quantitative composition of suspended solid material samples, vertical distribution of suspended solid materials by providing the possibility of sampling at any point in the vertical within a given cycle and minimizing perturbations introduced by the design itself into the space under study.
