Description

A utility model relates to containers for storage or transportation of products and materials, namely to rigid or semi-rigid containers that differ in design or material, in particular to boxes for transportation and storage of geological core of different lengths.

The core material extracted from the well is the main source of geological information when drilling exploration wells. Obtaining low-quality core, its loss during transportation and storage significantly reduce the effectiveness of geological research and make it necessary to conduct additional exploration work on additional exploration of deposits. Therefore, the safety of the obtained core material is very important.

According to the existing requirements of geological documentation, the entire core extracted from the core drilling well is subject to mandatory and thorough selection and placement in special core boxes with covers, which are taken out to the core storage as they are filled (Information was obtained from the Internet on the Drilling Portal website at - http://www.drillings.ru).

A well-known core box with compartments made of wood (see L. Berezkina. Instructions for field documentation of engineering-geological and prospecting and reconnaissance work in the search for roads / L.M. Berezkina, I.N. Gorbunov, N.S. Kovalevsky et al .; Under the general editorship of BC Smirnov. - Moscow, 1971. - [Electronic resource] Access mode: http://nordoc.ru/doc/42-42402).

A disadvantage of the known box is a short service life, high hygroscopicity of wood, the ability to warp upon drying and its fire hazard, as well as poor resistance to atmospheric phenomena.

A device for demonstrating visual material in geology is known, including a flat base with samples placed on it, made of a porous polymer material with a container placed in the bottom in the form of a box with compartments (see RF Utility Model Patent No. 114209, IPC G09F 5/00, publication 03/10/2012).

A disadvantage of the known device is the inability to recover from damage, is able to deform when heated.

The closest analogue of the claimed utility model are boxes for laying and storing drill core made of moisture-proof corrugated cardboard and (or) cellular polypropylene, developed by ADVANCE, consisting of a bottom, a cover and a separator-liner, which form cells for laying the core and, at the same time, , which is the framework for the entire box (see. Information on the website at - http: // core box.rf), taken as a prototype.

The disadvantage of the prototype is the low strength of the materials, the inability to recover after repair, the difficulty of reusing recycled materials.

The task to which the claimed utility model is directed is to improve the quality and reliability of the box for geological core.

The technical result achieved by the implementation of the claimed utility model consists in expanding the operational capabilities, as well as the field of use of the box due to the use of a thermoplastic wood-polymer composite in its manufacture.

The specified technical result is achieved in that in a box for a geological core, consisting of a frame including a bottom, side and rear walls, internal partitions, forming cells for laying core and a lid, according to a utility model, the parts are made of thermoplastic wood-polymer composite material, the lid on the inner side at the edges has a shoulder, the dimensions of which on the outer perimeter correspond to the internal dimensions of the box, made with the possibility of ensuring a tight fit of the lid on the frame of the box in the absence of accessories, while the inner partitions of the box are rigidly fixed to the bottom and rear wall of the frame.

The utility model is illustrated by drawings: in figure 1 - presents a box for a geological core, general view; figure 2 - box for geological core, top view, without cover; figure 3 - box for geological core, front view.

The box for the geological core contains a frame 1, consisting of a bottom 2, side walls 3, a back wall 4, internal partitions 5, forming cells 6 for laying core (not shown). On top of the box is closed by a lid 7 with hardware fittings. A collar 8 is made on the lid 7.

The utility model is as follows.

A box for a geological core is made of a thermoplastic wood-polymer composite (WPC) - a composition containing a polymer (chemical or natural origin) and wood filler.

Box details: frame 1, consisting of a bottom 2, side walls 3, a back wall 4, internal partitions 5 and a cover 7 are made by special forms by extrusion - injection molding from raw material preheated to the required plasticity. A box for a geological core is assembled from workpieces of parts obtained in this way that can be sawn, planed with a planer, drive nails into it.

The lid 7 is not screwed to the box, but simply slams, which makes it easy to use the box for geological core, as well as ease of use. Depending on the needs, the box can be assembled into three or more cells of different lengths for using core cores of diamond and carbide core drilling of various diameters, for example 46, 59 and 76 mm.

The main advantages of the design of the box from (WPC) for the geological core are:

- the material for the manufacture of the box is industrial and household waste, as well as granulate obtained by crushing decomposed products from (WPC), including used or discarded boxes for geological core;

- the box does not contain harmful components (for example, formaldehyde), therefore it is safe to use and has environmental benefits;

- wood-polymer composite (WPC) is fireproof, as it does not support combustion and is a self-extinguishing material;

- the box is highly resistant to insects, fungi, mold;

- the box has a surface devoid of defects such as cracks, knots and splitting;

- the box is non-hygroscopic, does not absorb moisture.

Using the proposed box for a geological core allows you to increase durability without special care for it, increase the ability to withstand significant mechanical loads, despite the relatively thin walls of the main parts from which it is made, as well as increase the stiffness and lightness of the box, while there is no warping even at large humidity changes.

The proposed design of the utility model may find application in the mining and exploration industry for laying and storing drill core.
