Abstract

The utility model is aimed at the effective selection of bottom sediments in water bodies, as well as the sediment of drilling waste (drill cuttings) in sludge pits, allowing you to effectively take samples with different density and fluidity, from wet and dense clays to liquid sludge, with minimal time and economic costs. great depth of the reservoir and selected sediments.

During introduction into the selected sediments, the first plate is displaced inside the cylinder and the second out. When a plate sample is removed under the influence of water flow and gravity of the selected deposits, they return to their original position and do not allow the selected deposits to be washed with water or fall out of the cylinder. When sampling very dense sediments, the sampler moves in circular motion along its axis with simultaneous pressing of the handle, and under the influence of rotation and pressure, the pointed and oblique end of the sampler enters the sampled sediments as a corkscrew.

Description

The utility model relates to the field of ecology and can be used for sampling of bottom sediments in water bodies, as well as sediment of drilling waste (drill cuttings) in sludge pits.

Known dumped sampler for sampling soil (RF patent No. 2057313, publ. 03/27/1996) containing a hollow cylindrical body with a piston mounted in it, a nozzle with a valve connected to the bow of the body, the tail of which is equipped with a stabilizer to keep the body in the vertical position. Two nozzles are made in the nozzle, communicating in the nose with the external environment of the cavity, one of which is connected to the external environment by means of a valve and equipped with a strainer located in the side of the nozzle for additional communication with the external environment, and the other cavity is made in the form of a tapering to the nose part of the nozzle of the curvilinear channel, the wide part of which is connected with the piston cavity of the body, and the narrow part is connected with the second cavity through the specified valve, and in the nose of the nozzle there is a fence n, located on the side of the curved channel.

A known bottom soil sampler (RF patent No. 2045753, publ. 10.10.1995) containing a core pipe with flexible core cutting elements installed in it having the possibility of longitudinal extension, covering the top end of the core pipe cover and cable. In order to increase reliability in operation, it is equipped with plungers attached to the lid, mounted in a cylinder rigidly connected to the core tube, provided with a piston covering it, placed in the housing, the piston cavity of which is filled with a working fluid and

communicated with the cavity of the cylinder by means of holes made in its wall, and the supra-piston cavity of the body is made open, the body and cylinder being connected to the cable, and the upper ends of the core cutting elements attached to the cover.

The disadvantages of the above samplers are the complexity of the device and the lack of mobility.

A known sample of bottom sediments (RF patent No. 2017953, publ. 08/15/1994), consisting of a body in the form of a cylindrical glass, inside of which there is a pipe with a restrictive ring on the outer surface, made of plastic materials that minimally sorb radionuclides, a tip with an axial channel, placed in the lower part of the glass, the piston with the rod, supports in the form of a horizontal ring with an opening for a cylindrical glass, on the lower surface of which ring projections are made, from a rack with crossbars, earrings and a locking mechanism of the rod, while the tip is made with an outer annular groove and an axial channel equal to the inner diameter of the nozzle, and the rod is connected by its fixing mechanism to the earring and is hollow, with radial holes and a check valve in its cavity, while the piston and rod are placed in the nozzle and form a chamber for the sample with the housing, hydraulically connected to the external space through the radial holes of the stem and its check valve, and the support is made with a plate spring-loaded relative to the support, is installed and with the possibility of horizontal movement, fixing the tip in its outer annular groove and overlapping the axial channel of the tip in its extreme upper position. The sampler is equipped with plates mounted on the crossbars along its axis.

The disadvantages of this invention are the design complexity and the inability to select liquid deposits such as sludge.

The task that the proposed utility model is aimed at is the effective selection of bottom sediments in water bodies, as well as the sediment of drilling waste (drill cuttings) in sludge pits, which makes it possible to efficiently take samples with different density and fluidity from wet ones with the least time and cost. and dense clays to liquid sludge from a great depth of the reservoir and selected sediments.

During the creation, such issues as the creation of a sampler with such design features that would allow sampling from different depths of the reservoir with different density and fluidity, from wet and dense clays to liquid sludge, while having mobility due to the collapsible handle and the simplicity of the device, were solved.

The technical result is achieved by the fact that a handle of the required length is assembled from the sections and attached to the cylinder, then the sampler is immersed in water and introduced into selected deposits. During introduction into the selected sediments, the first plate leaves inside the cylinder 10 and the second out 11. The samples are removed by the flow of water and the gravity of the selected deposits to their original position and they do not allow the selected deposits to be washed with water or fall out of the cylinder. When a sampler is removed from the water with a sample, it is removed by standard methods. When sampling very dense sediments, the sampler moves in circular motion along its axis with simultaneous pressing of the handle, and under the influence of rotation and pressure, the pointed and oblique end of the sampler enters the sampled sediments as a corkscrew.

The device (figure 1) is a sampler in the form of a hollow cylinder 1, which has a beveled and pointed end 2, which allows easy penetration into the selected substrate; the cylinder is equipped with moving plates on the mount (connection) of the hinge type 3, the first plate 4 is fixed from the inside, the second plate 5 is in the upper part.

Moving plates do not allow selected deposits to fall out or wash out when they are removed from the reservoir. On the inner side of the cylinder there is a stop 6, which serves to hold the plate. By welding or by any other method 7, a collapsible type 8 handle is attached, disassembled into sections, which allows you to choose its optimal length. The sections are fastened together by bolts 9 through holes in the end sections.

Using the proposed utility model allows you to effectively, with the least time and economic costs, to select deposits of different fluidity and density from a large depth of the reservoir and selected deposits.
