Description

The utility model relates to the field of creating demonstration stands and is intended for the preparation and conduct of primary and repeated (regular) instruction on the safe use of in-house gas equipment (hereinafter referred to as VDGO) by subscribers during the initial and repeated start-up of natural gas into residential, industrial and public buildings and premises.

Initial briefing is carried out by a specialized organization prior to the performance of work on the initial start-up of gas in the VDGO, as well as before the owners (users) move into the gasified living quarters belonging to them by right of ownership, when transferring existing household gas-using equipment from one type of gaseous fuel to another, when transferring an existing one. household equipment for the purpose of food preparation, heating and (or) hot water supply from solid fuel (coal, firewood, peat) to gaseous fuel the approval of the instructions for the safe use of gas in meeting household needs ”].

When organizing control over the provision of safety measures when using VDGO, it is checked that specialized organizations conduct instructions for the owners (tenants, tenants) of apartments and buildings of private housing stock, as well as those responsible for the safe operation of VDGO of public buildings (public premises) before the initial start-up of gas (natural and liquefied hydrocarbon gases, including from individual cylinder installations), as well as before moving into apartments with an operating VDGO, on measures for the safe use of VDGO [clause 3.1, section III of the order of the Federal Service for Environmental, Technological and Nuclear Supervision (Rostekhnadzor) dated 02.12.2009 No. 1001 "On approval of guidelines for monitoring the maintenance and condition of indoor gas equipment"].

There is a known model of a preparatory development for demonstrating explosions of dust and methane-air mixture, selected by the applicant as a prototype, allowing to simulate an explosion of dust and methane-air mixture in a mine working, including a model of a mine working adjacent to the model of a dead-end part of a preparatory working, in the inner part of the model of a dead-end part of a preparatory working there are models of an electric cable, a magnetic starter, a ventilation bulkhead with a two-leaf door, a dummy of a miner, a local ventilation unit with operating and backup fans, a ventilation pipeline, a shale dam, a collapsed rock, a lighting network, devices are mounted on the back wall of the dead-end part of the development mine for the supply of coal dust and methane [patent of the Russian Federation No. RU 67756, IPC G09B 23/06 authors Lavrika G.V. and others, priority date 23.05.2007, publ. 27.10.2007, bul. No. 30].

The disadvantage of the prototype is the lack of applicability for conducting primary and repeated (next) instructions on the safe use of VDGO by subscribers during the initial and repeated launch of natural gas into residential, industrial and public buildings and premises, since the prototype lacks elements that allow demonstrating a domestic gas explosion in the layout living quarters.

The technical problem of the claimed utility model is the creation of a device that provides a demonstration of a domestic gas explosion in a dwelling layout.

The technical result consists in providing a demonstration of the explosion of domestic gas in the layout of the living quarters.

The technical result in a device for demonstrating a domestic gas explosion in a living room model containing a base, a start button connected to a network cable having a plug, which are fixed on the outside of the model, is achieved by the fact that a living room model is rigidly fixed on the base, inside which is fixed combustion chamber, the inlet of the combustion chamber is an inlet for gas supply, the outlet of the combustion chamber is closed with a plug, and on the sides of the combustion chamber there are electrodes that are connected by means of electric wires to the transformer, and the transformer is connected by means of electrical wires to the start button.

The claimed technical solution is illustrated by drawings.

FIG. 1 shows an electrical diagram of the connection of the elements of the device, FIG. 2 shows a perspective view of the device, FIG. 3 shows an example of implementation.

A device for demonstrating a domestic gas explosion in a living room model contains a base 1, a start button 2 connected to a network cable 3 with a plug, which are fixed on the outside of the living room model 4, rigidly fixed, for example, with fasteners, on the base 1 and , for example, chipboard, fiberboard with decorative foam trim. Inside the living room layout 4 is fixed, for example, with fasteners, the combustion chamber 5, made, for example, of a piece of pipe with a diameter of 89 mm, the inlet of the combustion chamber 5 is the inlet for gas supply, and the outlet of the combustion chamber 5 is closed with a plug 6, and on the sides the combustion chamber 5 has electrodes 7, which are connected by means of electrical wires 8 to a transformer 9, for example, a gas-light transformer of the TG-1020K type, designed to operate in a network with a nominal voltage of 220 V and connected to the start button 2.

All elements of the device are interconnected and represent a single structure.

Consider the proposed technical solution in use.

When conducting the initial and repeated (next) briefing on the safe use of VDHO to subscribers for better assimilation of the material, increasing visibility and developing an idea of the danger of natural gas, an explosion of household gas is demonstrated in the layout of the living quarters 2.

To do this, by connecting the mains cable 3 to the contact network, the rated voltage of 220 V is supplied to the transformer 9. Then, the required amount of gas is supplied to the combustion chamber 5 from a gas source, for example from a cylinder installation or from a gas pipe through a flexible hose, for example, at a pressure of 0.05 MPa. By pressing the start button 2, the voltage from the transformer 9 through the electric wires 8 is applied to the electrodes 7, after which the gas-air mixture ignites in the combustion chamber 5 and the excess pressure at the outlet of the combustion chamber 5 displaces the plug 6, which in turn knocks out part of the wall decoration of the living room layout 4.

Further, if it is necessary to re-demonstrate the explosion of domestic gas, part of the wall decoration of the layout of the living quarters 2 returns to its original position, the plug 6 is installed back at the outlet of the combustion chamber 5 and the sequence of actions is repeated.

The proposed design of the claimed technical solution provides a demonstration of the explosion of domestic gas in the layout of the living quarters without the need for blowing with compressed air during subsequent operation. Thus, the technical problem has been solved and the technical result has been achieved.

The analysis of known technical solutions, carried out on the basis of scientific, technical and patent documentation, showed that the set of essential features of the proposed technical solution is unknown from the prior art, therefore, it meets the conditions of patentability of a utility model novelty.

The claimed technical solution is industrially applicable, manufactured on standard equipment with the use of modern materials and technologies at hand, and is used by OOO Gazprom transgaz Kazan.
