(54) DEVICE FOR SAMPLING SAMPLES

SUSPENDED NANOSES IN THE SIDGE LAYER

ON THE SEA SHELF

one

The invention relates to the study of the physical properties of suspensions, namely the measurement of the concentrations of suspended solids in a liquid and can be used to study the dynamics of marine sediments on the shelf.

Known invention of the nanometer nanometer. This batometer is a tank that is installed in the stream for a long time and collects particles suspended in water. Bamboo poles with holes in separate natural sections 1 are used as accumulators.

These posts have a number of disadvantages, the main of which is the small depth of the installation of the poles (no more than 10 m), the complexity and complexity of the process of extracting the collected sample.

The closest to the proposed technical entity is an autonomous measuring station consisting of a metal tripod, to the side edges of which with the help of cantilever holders I attach nanostandifiers. The design of the drives provides for the possibility of their fixation in the suspension opened for access and in the closed

position The installation of the tripod on the bottom of the light boat is carried out from the board of the light boat, and the opening and closing of the drives by divers (2.,

The disadvantage of these drives is the need to use diving labor, which limits the possibility of setting this measuring station to the depths available to the diver. This means that even when operating at depths greater than 12 m, the servicing vessel must be equipped with an expensive recompression chamber, and deeper than 45 m and with a lowering device (diving bell).

The purpose of the invention is to increase the depth of installation of the measuring station to one hundred and more meters with the complete elimination of expensive diving operations.

This goal is achieved by the fact that a device for sampling suspended sediments in the bottom layer on the sea shelf, which contains a cassette of nanoscalers; having radial through-holes, provided with a cylindrical body with a load in the lower part, a cable with a cable and an acoustic-acoustic breaker with a buiper attached to the housing for connection with the buoy, while the cartridge of the battomstra nano-accumulator is installed and the cylindrical housing with a gap, and the housing is made with through holes placed in height according to the holes of the cassette. The nanosynapula-pill-cassette cassette has a guiding longitudinal groove and is placed with a gap of 2-3 mm in a cylindrical body that has a matching guide protrusion. In the bottom part of the housing there is an element of time delay and pins limiting the stroke of the cartridge of the nanoscalers of the bathometer. In the upper part, the casing is provided with a plug with a central opening for connecting the cartridge of the nanoscalers with a billet, whose cable is attached to the buoy. The diameter of the through-holes, equally spaced around the perimeter, made on the side surfaces of the housing is 2-4 mm larger than the diameter of the holes of the cartridge of the nanoscalers cartridge. FIG. 1 shows the nanoscaler bathometer, general view; in fig. 2 - the upper part of the device with vyushchuyas and the lower part of the device with the load, the adaptation of the time delay, teeth; in fig. 3 — a device for sampling sediment in the bottom layer on the sea shelf; general view; FIG. 4 is a section A-A in FIG. 2. The device contains nanoscalers-nanoscalers 1, connected with a thread into a cassette of any length required by the experimental conditions, guiding the longitudinal groove 2, made on the bathometers of accumulators, a cylindrical body .3, on the side surfaces of which at an equal distance from each other from each other there are circular through holes 4, equally spaced around the perimeter, guiding a longitudinal protrusion 5 located on the inner wall of the housing, which when assembling the device enters the longitudinal groove 2 of the nanoscale to ensure complete coincidence of the holes at the beginning of the operation of the nanoscalers. At the bottom of the housing 3, pins 6 are located, which serve to limit the stroke of the cartridge of the nanoshoon storage bin, Zaglushka 7 with a hole in the center, located in the upper part of the hull, restricts from above the free running of the cartridge of the nanoshoon storage bin. View 8 is a freely rotating drum with a cable wound around it, the length of which is determined by the depth of the device. A bolt 9, a free passage through the hole in the plug, connects the cartridge of the nanoscalers with a viewer. Element 10 for delaying the opening of the holes I1 of the nanoscale accumulator is installed at the bottom of the body between the pins and is a chemical substance pressed into a cylinder of a certain length, dissolving in seawater for a certain time determined by the conditions of the experiment. The device is attached to a metal eye 12 bu 13 with a bump and a view cable. A hydroacoustic breaker 14 n hook 15 is installed in the upper part of the body. A load is installed in the lower part of the body. The assembly of the device is carried out on the shore or on the deck of the vessel and proceeds as follows: a cassette of the required length is assembled from the individual nanoscalers 1 bathometer. A time delay element 10 is inserted between the pins 6 inside the housing 3, the cassette of the nanostand collectors is inserted in such a way that the longitudinal groove 2 and the protrusion 5 coincide. A bolt 9 is inserted into the opening of the plug 7 and the plug is fixed in the housing 3. A bolt 8 is attached to the bolt 9 with a cable and attached to the cable behind the eye 12 by the buoy 13. The buoy bup is connected to the housing 3 through a mechanical gripping of the sonar disconnector 14 to the housing 3. The hydro acoustic buoy keeps the buoy from prematurely floating up. The device works as follows. The device is installed on the bottom at a selected point to the desired depth using a small hand or ship winch. Having hooked the cable from the winch to the hook 15, the device can be lowered to the bottom. When the bottom is reached, the tension of the cable weakens and slides off the hook easily. After a predetermined time, the time delay element dissolves and the cassette of the nanoscaler-type bathometers sags under its own gravity, and the apertures of the 11-nanoscalers-nanoscalers coincide with the apertures 4 in the housing. The coincidence of the holes 4 and 11 is due to the presence of limiting pins and longitudinal guideways of the groove and the protrusion. Falling through the holes, the slurry begins to settle and accumulate in the bathometers. Upon completion of work from the ship’s side, a signal is sent to the sonar breaker 14, the capture of which releases the buoy. Floating to the surface, the buoy unwinds the cable that is wound on a drum. A buoy painted in a bright color is easy to spot in the sea, and then lift the device aboard the vessel behind a cable. During the ascent. bathometers are closed. This is due to the fact that the device is lifted behind the cartridge of nanoscalers. gels, while the shell sags under its own body. As a result, the pipes (body and cassette) are shifted relative to each other already in the opposite direction, which allows closing the openings of the nanoscalers. This prevents sample leakage from the nanoscalers of the bathometer-nanoscalers during the lifting of the device to the surface.

The invention provides the ability to obtain detailed information on the vertical distribution of suspended matter of the bottom layer of arbitrary thickness, the ability to change the study details and the thickness of the studied layer, averaging the information obtained for any researcher interested in term, significantly reduces the research expeditionary work by eliminating the expensive diving operations, which also allows using a device for selecting pr of the notified particles over the entire slit (the depth Gödel is .besa calculation load, long rope, dyn-emnostyu boo, reliability sonar breaker) znachi.telno simplified maintenance of measuring stations, thereby povyschaets performance of research, reliability Retrieving the post, in the absence of additional marking buoys on the surface | fixing the location of the work station is determined only by the reliability of the operation of the sonar switch. With good breakers, the probability of detecting and maintaining the device is 100%, and it also makes it easy to manufacture, operate and maintain the structure itself. At the same time, the reliability of the device at high depths remains high.
