Description

The utility model relates to the field of railway technology, namely to isothermal cars.

A device for draining water from a refrigerator car is known from the prior art, containing a vertical drain pipe attached at the upper end to the flooring and at the bottom communicating with the atmosphere, a float outlet valve installed in the pipe, and a water seal located in the thermal insulation zone of the floor of the car (SU 1172770 , class B60P 3/20, F25D 21/14, published 07/05/83).

The disadvantage of the known solution is high heat transfer and, for this reason, the inability to maintain the required temperature.

From the RF patent No. 219694 for a utility model, a drainage device for an isothermal car is known, containing a drain and a cover hingedly attached to it, in the closed position fixed by a hinged bolt with an eye and a wing nut, while the drain is formed by two concentrically located shells, and the cover is formed by one shell , closed on both sides by plates, and the drainage cavities between the shells and the cover cavity are filled with thermal insulation. The drainage device according to patent 219694 contains an inextricable connection of metal elements.

The drainage device for an isothermal car according to patent No. 219694 was chosen as the closest analogue.

The disadvantage of the technical solution according to patent No. 219694 is the complexity of the design, as well as high heat transfer due to the formation of temperature bridges as a result of the inextricable connection of metal elements, and for this reason the inability to maintain the required temperature in the car.

The technical problem solved by the proposed utility model is high heat transfer.

The technical result achieved by the utility model is a reduction in heat transfer with a simple design.

The technical result is achieved due to the fact that in an isothermal car containing a body with a frame, a chassis, automatic coupling devices, brake equipment, doors, while the body contains a frame mounted on the frame, sheets of inner and outer skin and insulation between these sheets, in on the body floor there is at least one drain device passing through the floor covering and the frame, the drain device contains a pipe, a plug, a cover, according to the utility model , the drain device contains a transition pipe located between the pipe and the floor covering, wherein the transition pipe is made of composite material .

An isothermal car may contain a refrigeration and heating unit.

An isothermal car can contain two drain devices.

The transition pipe of the drainage device can be made of any polymer composite material, in particular fiberglass, carbon fiber, boron plastic, organoplastic, textolite.

The drain cover may include a counterweight.

Insulation can be made of polyurethane foam, polyisocyanurate foam, or expanded polystyrene.

The claimed utility model is illustrated by drawings.

In fig. Figure 1 shows a general view of the proposed isothermal car.

In fig. 2 bottom view of the location of the drainage device.

The inventive insulated car contains a body 1 with a frame 2, a chassis 3, automatic coupling devices 4, braking equipment 5, doors 6. The body 1 contains a frame mounted on a frame 2, sheets of inner 7 and outer 8 skin and insulation between these sheets. In the floor of the body there is at least one drain device 9, passing through the flooring 10 and the frame 2, the drain device 9 contains a pipe 9.1, a transition pipe 9.2, a plug 9.3, a cover 9.4. The transition pipe 9.2 of the drain device 9, located between the pipe 9.1 and the flooring 10, is made of composite material.

Making pipe 9.2 from a composite material allows you to eliminate the thermal bridge between the frame and the flooring, thereby reducing heat transfer and maintaining the required temperature inside the isothermal car.

One such drain device 9 is enough to achieve the technical result, while a specialist understands that it is possible to install, for example, two drain devices - for example, at different ends of the car. When using one or more drain devices, the technical result is achieved. This interpretation of a characteristic implies a characteristic of a characteristic expressed as a range of continuously changing parameter values, which is not considered as alternative characteristics.

At the same time, the simplicity of the design was ensured - a reduction in heat transfer was achieved only by changing the material of one element; otherwise, a standard design was used.

An isothermal car can be designed as a thermos car (without a refrigeration and heating unit).

An isothermal car can be designed as a refrigerated car and contain a refrigeration and heating unit.

The transition pipe 9.2 of the drain device 9 can be made of any polymer composite material, in particular fiberglass, carbon fiber, boron plastic, organoplastic, textolite. These materials provide high strength and reliability, while reducing heat transfer and maintaining the required temperature in the car.

The drain cover 9.4 may contain a counterweight 9.5.

Insulation can be made of polyurethane foam, polyisocyanurate foam, or expanded polystyrene.

Calculations were performed using the example of an isothermal car, in which the transition pipe 9.2 of the drain device 9 was made of a composite material (in this experimental device fiberglass was used). Calculations showed that, compared to the analogue, heat transfer in the experimental product was reduced by 190 times.

Consequently, the claimed utility model makes it possible to provide a technical result consisting in a reduction in heat transfer with a simple design.
