Description

The invention relates to devices for sampling silty deposits of fluid and viscous consistency and can be used for sampling from various depths of any reservoirs and wells. The invention can find the widest application when testing lacustrine sapropel deposits and other bottom sediments of the appropriate consistency.

A similar device for testing bottom sediments is known, containing a core barrel equipped with a cutting shoe in the lower part. At the upper end of the core barrel there is a guide tube, on which a steel pipe is attached, which serves to install variable weight loads, as well as to mount four stabilizers. In this case, one of the stabilizers is provided with a flat cover and is movably mounted on the axis. When loosened at the moment of impact of the soil carrier on the bottom, the latch assumes a vertical position, which allows the cover to block the upper opening of the soil carrier during the extraction of the tube, preventing the sample from falling out (see I.G. Shelkovnikov, A.V. Lukoshkov. Technical means of underwater exploration drilling and sampling. From Leningrad State University, L., 1979, pp. 77-78).

The disadvantage of analog is the doubtful possibility of testing fluid deposits, since it lacks a device that locks the lower end of the soil intake.

A similar device for sampling a fluid material is known, containing a vertically mounted ground pipe connected to an air pipe connected to a line for supplying compressed air and located parallel to the ground pipe, and a sampler made in the form of a glass covering the upper half of the ground pipe, and the ground pipe is rigidly is fixed in the sleeve, and the upper end of the ground pipe is mounted below the upper end of the sleeve at 1/6 part of the length of the sleeve, while the connection of the ground and air pipes is carried out by inserting the lower end of the air pipe into the side wall of the ground pipe at a height of 2 centimeters from the lower end of the ground pipe (see RF patent No. 2030729, IPC G01N 1/20, G01N 1/10, published 1995, March 10).

The disadvantage of the analogue is the additional dilution of the tested material with a jet of water during its extraction and violation of the structure of the sample, which excludes the provision of a qualitative and quantitative assessment of the sample taken, as well as the possibility of testing only the upper layer of the tested deposit.

The closest device for the same purpose to the claimed invention in terms of a combination of features is a universal sampler of bottom sediments and drill cuttings, which is a hollow cylinder, to which a collapsible type handle is attached by welding or otherwise, the sections of which are fastened together through holes in the end sections bolts, and the end of the sampler is made bevelled and pointed, the cylinder is made equipped with moving plates on a mount (connection) of a hinge type, the first plate is fixed from the inside, the second plate is fixed at the top (see RF patent No. 73396 U1, IPC E21B 49/02, published 2008 ,05,20, selected as a prototype).

The disadvantage of the prototype is that the device is inoperable. The formula of the utility model indicates that the sampler (position 1 in the prototype) is made in the form of a hollow cylinder. The first plate (position 4 in the prototype) is fixed from the inside on the hinge (position 3 in the prototype). Since the first plate is fixed from the inside of the cylinder, then the shape of this plate (position 4 in the prototype) is in the form of a round disk. Figure 1 of the prototype (position 10) shows that the plate is vertical! In order for the plate to take this vertical position, the hollow cylinder (position 1 of the prototype) must be square or rectangular. Since a hollow cylinder is indicated in the formula, the disk mounted on a hinge by its edge will rise to the top by about 20-25 degrees. And he can't stand upright! The entrance to the hollow cylinder will be slightly ajar in the form of a narrow slot.

The technical problem is that it is necessary to ensure the operability of the sampler.

EFFECT: ensuring complete opening of the bottom of the hollow cylinder.

This technical result is achieved by the fact that the well-known sampling device, consisting of a rod attached to a hollow cylinder, the upper end of which is equipped with a hinged cover, and in the lower part of the hollow cylinder on the axis there is a damper, the peculiarity is that the damper is made ellipsoidal and is fixed by its the middle part on the rotary axis, which is L-shaped and its bent section is brought out of the hollow cylinder and covered with a shield, in addition, a cord is fixed at the end of the bent section, and inside the hollow cylinder, a support made of magnetic material is installed to fix the ellipsoid damper in a vertical position, equipped at the ends with magnets interacting either with the support or with the wall of the hollow cylinder.

Additionally, the invention is characterized by the fact that the support is made in the form of a strip fixed on the inner surface of the hollow cylinder.

Additionally, the invention is characterized in that the hinged lid is provided with a stop.

The invention is illustrated by drawings.

Figure 4 - view of the lower part of the device when removed from the reservoir. Safety shield not shown.

The drawings show. Rod 1 attached to the hollow cylinder 2. Bracket 3 attached to the top of the hollow cylinder with axis 4, on which the hinged cover 5 is fixed, the shank of which is equipped with a stop 6 interacting with the bracket 3. The stop 6 does not allow the hinged cover 5 to rise at a greater angle when immersed devices. The ellipsoid damper 7 is fixed with its middle part on the rotary axis 8, which is L-shaped and its bent section 9 is brought out, a hollow cylinder 2, inside of which a support 10 made of magnetic material is installed to fix the ellipsoid damper 7 in a vertical position, The support 10 is made in the form of a strip fixed on the inner surface of the hollow cylinder 2. The support 10 can be placed both from above (see figure 1) and from below. The elliptical shutter 7 is equipped at the ends with magnets 11 and 12, which fix it in a vertical position, if the magnet 11 touches the support 10, while the bottom of the hollow cylinder is open. And when the elliptical shutter is turned and the magnets 11 and 12 touch the inner surface of the hollow cylinder 2, then its bottom is closed. The cord 13 is fixed at the end of the bent section 9 of the rotary axis 8. Horizontal plates 14 and 15 are fixed on the outer surface of the hollow cylinder 2, to which the shield 16 is attached with screws.

The device works as follows. We lower the device into the reservoir (see figure 1). The oncoming flow of liquid through the open bottom of the hollow cylinder 2 will open the hinged cover 5. If the depth is large, then the rod is made collapsible. We twist the collapsible parts of the rod together. We lower the device to the desired depth and begin to pull the cord 16. We overcome the force of pressing the magnet 11 to the support 10. The elliptical flap 7 will turn and rest against the inner surface of the hollow cylinder, and the magnets 11 and 12 will securely hold the latter in the closed position. You can remove the device from the reservoir. The hinged cover 6 is closed by a stream of bottom sediments flowing from above. We disassemble the bar 2 into its component parts. We remove the device from the reservoir. To extract the sample from the hollow cylinder 2, move the elliptical shutter 7 to the vertical position. The sample is removed.

After washing the device with water, you can immerse it in a pond for another sample.
