Description

The utility model relates to devices for sampling gaseous media at near atmospheric pressure and can be used in places inaccessible and undesirable for the operator to find, for example, in sewer and / or ventilation wells, vertical mine workings, in tanks of collection and / or storage systems oil, oil products and / or other low-boiling (volatile) liquids.

The prior art for this type of device can be characterized by such objects known from publicly available information sources as, for example, according to the inventions: SU 819613 C1 1978; RU 2084858 C1 07.20.97; RU 2094610 C1 10.27.97; RU 2126148 C1 02.10.99; RU 2158421 C1 1999; RU 2217728 C2 11.27.03 and for utility models: RU 1748 U1 02/08/94; RU 1749 U1 03/14/94; RU 60724 U1 09/26/06. In known devices, the main unit / element is a container container made of a specific material of any particular geometric shape, equipped with bends, necks and / or holes for filling a gaseous medium and releasing this medium to a measuring and analyzing installation. For sealing, that is, for locking / closing a sample in a container container during transportation of the latter, known devices are equipped with locking elements in the form of valves, valves, taps, clamps and the like structures; These devices for sampling also contain channels for supplying and discharging a sample of the medium, made in the form of tubes, hoses or hoses.

The most characteristic disadvantage of the known devices is the need to perform a number of preliminary and / or final operations and techniques, eliminating the distortion of the sample composition of the gaseous medium, since its representativeness depends on the specific execution, condition and serviceability of the gaseous medium supply channel and shut-off elements; there is also a design flaw - the presence of so-called "parasitic" volumes, cavities and voids in the channels of movement of the gaseous medium in the selection process. In addition, the implementation of the container container in the form of, for example, a cylinder-piston pair, that is, in the form of a syringe, significantly limits the sample in volume, and container containers of this type, but of significantly larger sizes, are inconvenient to operate, especially with multiple procedures sampling, in addition, they are difficult to manufacture.

The closest to the claimed technical solution (both structurally and functionally) is a device according to RD 153-39-019-97 ("Guidelines for the determination of technological oil losses at enterprises of oil companies of the Russian Federation", Ufa, IPTER publication, 1997, Fig. 9 and paragraphs 10.8.1 ... 10.8.3.) containing a container container in the form of a glass bottle with a capacity of 330 cm ³ ; cork closing the bottle; metal tubes placed in a cork inserted at one end into the bottle; at the other ends of the metal tubes are rubber hoses with clamps at the end sections near the bottle.

The disadvantages of the known device include the same ones noted above, namely: constructive (the presence of tubes, hoses and, accordingly, the presence of harmful / spurious cavities), as well as operational (the presence of a number of conditions, restrictions and sequence of performing certain operations and techniques ; for example, before filling the container container, it is necessary to repeatedly replace the gaseous medium in the cavity of the filling hose, having previously determined the location of the sampling point, then connect the container container, fill it, seal the sample, and all this taking into account equalization of ambient temperatures and the device in the event of a significant difference. The use of glass products as container containers is also not the best option for implementing the device.

The implementation of the object according to the claimed utility model provides a solution to such a technical problem as a significant increase in its consumer properties by optimizing the design while reducing manufacturing and operating costs.

The problem is solved in that the known prototype device, containing, according to the description, a container container with a neck and a locking unit, a measuring element for tripping and positioning the latter at the sampling point, is equipped with a glass-like case in which the container container is placed with a neck down with the stop of the latter in the bottom of the body and the possibility of limited reciprocating axial movement of the container container by the standard value N relative to the body, the measuring element is connected to the latter and equipped with in units of length, an easily removable load is placed on the neck of the container container, and a removable gripper holder is placed on top of the container container, equipped with a suspension element in the form of, for example, a cord fixed at the end and having the same length and the measuring element on case.

A significant additional difference of the proposed device is that on the bottom of the body, under the neck of the container container, a plate of porous material, such as foam rubber, is fixed, and the load on the neck of the container container and its removable gripper holder are made with an external contour similar to the cross section of the body to ensure the centering of the container container along it, that is, the casing, of the longitudinal axis OO.

A comparative analysis of the claimed device, as a set of essential features (including distinctive ones), with solutions known from the regulatory, technical and patent documentation, allows us to argue that the proposed technical solution meets the "criteria" of the utility model, that is, it has "novelty" and "Industrial applicability."

The graphic materials show the initial state of the device (Fig. 1), its state at the time of the start of sampling (Fig. 2) and the device before lifting it after sampling (Fig. 3).

The device (Fig. 1) contains a container container 1 with a neck 2 located in a glass-like body 3, and the container container is placed with its neck downward with the latter resting in the bottom 4 of the body and the possibility of limited reciprocal axial movement of the container container by a standard value N relative to the body. The device also contains a measuring element 5 connected to the upper part of the housing and provided with labels of 6 units of length; an easily removable load 7 is placed on the neck of the container container, and a removable gripper holder 8 is provided on top of the container container, provided with a suspension element in the form of, for example, a cord 9, with an end fixed to the holder 8 and having the same length as the measuring element 5, connected to the housing 3. Under the neck of the container container at the bottom of the housing, a plate 10 of elastomer or porous material, for example, rubber or foam, can be fixed. The load 7 on the neck of the container container and its removable gripper-holder 8 can be made with an external contour similar to the cross-section of the body to ensure that the container container is centered along its, that is, the body, longitudinal axis O-O; but this is only if placed in a large case (under a half-liter bottle) of a container of smaller capacity and dimensions.

The device operates (see figures 1, 2 and 3) as follows. A container container filled with a liquid that is not capable of absorbing / dissolving gases from the gaseous medium intended for selection, for example, a saturated aqueous solution of any salt, is placed in the housing 3. As a container container, it is preferable to use a plastic bottle (PET in accordance with GOST R 51760-2001 Consumer polymer packaging. General technical conditions) of the required volume, given that a significant advantage in terms of capacity is the gamut of these products with a completely identical threaded neck and locking element (cork) for all sizes and types. After installing the container container 1 in the housing 3, instead of a typical plug (below the liquid level), load 7 is screwed onto the neck and put on (fix) the bottom holder (holder) 8 with the cord 9. The device is lowered according to the dimensional marks element 5 to the required depth in the hatch of the tank or well, maintaining the cord 9 in a state without tension, but also without sagging, and then, while holding the measuring element 5 in motionless, raise the container container 1 on the cord 9 by the standard value N relative to the housing 3. Fluid b, flowing into the glass-like body 3 from the container 1, is replaced in the last selected gaseous medium. After filling the container container 1 with gaseous medium, that is, after the liquid has been completely drained into the housing 3, the cord 9 is released, the sample is first locked in the container container 1 by immersing it in the liquid, and then by additional sealing of the neck 2 , which has risen to the bottom 4 of the glass-like body 3. By means of the measuring element 5, the device is removed upward. To transport a container container somewhere instead of a load 7, a standard plug is screwed up (under the liquid level).
