Description

The utility model relates to devices for sampling silty sediments and can be used for sampling from any depths of water bodies and wells.

Known sampler for Bikker bottom sediments (http://himpribor.ru/yendors). It consists of a core pipe, interchangeable columns and a rubber membrane, a piston mechanism and a pump.

The disadvantage of this analogue is the complexity of the design.

The closest in technical essence and the achieved effect to the proposed is a percussion sampler for bottom sediments, containing a core tube with a piston placed in it, a core receiver cavity, a brake disc, an impact mechanism in the form of pneumatic chambers (Utility Model Patent No. 42063, Multi-impact Vacuum-Pneumatic Sampler bottom sediments, IPC Е21В 49/92, G01N 1/08, dated November 20, 2004).

The disadvantage of the closest analogue is the complexity of the design and the complexity of operation in the field.

The objective of the proposed solution is to eliminate these drawbacks, namely, simplifying the design and improving operating conditions.

The problem is solved in that in a percussion sampler for bottom sediments containing a core pipe and a striking mechanism with a striker, according to the proposed solution, a thread is made in the upper part of the core pipe, on which a removable upper cover with holes in the upper part is fitted. On the top cover, eyes are fixed on it with guides made in them parallel to the axis of the sampler. The lid is connected to the striker by rods installed in the guide eyes of the lid. One end of the rods is fixed on the upper end of the striker, and the second end has a spring-loaded clamp position of the striker relative to the pipe. The shock mechanism is made in the form of a load suspended on a cable. Moreover, the striker position lock relative to the pipe is made in the form of a latch interacting with the conical surface of the core pipe and spring-loaded relative to it.

The proposed sampler is illustrated in FIG. 1-4, where in FIG. 1 shows a general view of the cocked sampler; FIG. 2 - the same at the time of soil intake, in FIG. 3 is a section AA of FIG. 1, in FIG. 4 - tearing out I of FIG. 2.

The proposed impact sampler contains a core pipe 1 having a thread in the upper part, on which a removable top cover 2 is fitted. The cover 2 has eyelets 3 in which guides 4 are arranged parallel to the axis of the sampler. A spike 5 is located above the top cover 2. rods 6, in which one end is fixed on the upper part of the striker 5, and on the second end is fixed the position lock of the striker 5 relative to the core pipe 1, which is made in the form of a latch 7, the conical surface 8 of the core pipe 1, ruzyne 9. The load 10 on the cable 11 is attached and fixed to the lid 2.

The sampler works as follows.

On the core pipe 1 put on the top cover 2 with holes in the upper part. From a boat or from ice to water on a metal cable. A sampler prepared for operation is omitted (Fig. 1). Lowering the sampler is fast, but without jerking. When reaching the bottom soil under the own weight of the sampler, core pipe 1 enters a certain depth. When the striker 5 stops, it slides down along the rods 6, made in the guides 4 of the eyes 3 of the cover 2, and the cable 11, locking the surface of the cover 2 from above. At the same time, the latches 7 mounted on the lower end of the rods 6 slide along the conical surface 8 and the pipe 1 and fix the striker 5. The load 10 on the cable 11 is located above the striker 5 and is mounted on the cover 2.

In the case of loose bottom sediments, the core pipe may be completely filled with 1 bottom sediment. In this case, the sampler can be lifted and the sample extracted by extrusion using a hand piston.

In the case of medium and compacted bottom sediments, a massive impact load 10 is sent along the cable 11, which clogs the core pipe 1 into the bottom soil.

According to the proposed solution, a prototype of the proposed sampler for bottom sediments was made. The core pipe was made with an inner diameter of 6 cm and a length of 60 cm. The cover consists of a hollow cylinder 10 cm long with holes in the upper part. The cable is made with a diameter of 3 mm. Two tubes (eyes) 5 cm long are welded to the lid. A massive removable cylindrical load weighing 10 kg is attached to the cable. A sampler of this type reliably selects silty bottom sediments at a depth of 0.5 m without disturbing them.

The proposed sampler will find application in scientific research on rivers, lakes, reservoirs to study the surface layer of bottom sediments susceptible to anthropogenic impact, as well as for the selection of bacterial benthic flora. The sampler will also find application for environmental observations in teaching students geographic, biological and environmental specialization.
