Description

The utility model relates to transport, and more particularly to pipeline transport.

Known pipeline transport (RU No. 70239, B65G 53/36; B65G 51/00, 01/20/2008) containing, along with an external cylindrical rigid pipeline, an internal pipeline with a flexible wall, the annular space being filled with a gaseous inert medium, while the working medium is transported by internal pipeline under a pressure of at least 1.01 inert pressure, sealed containers placed in the flow of the working medium and in which various, including bulky, cargoes and / or passengers are placed. The containers are equipped with linear electric motors, providing regulation of the mode of transportation of containers in manual and automatic mode and a system for stabilizing their position in space in the form of guides and rollers.

The location of linear electric motors in containers leads to an increase in the total mass of the container, as well as the need for the location of power supplies for linear electric motors on board the container, resulting in low efficiency of the pipeline transport.

The wagon of the Yansufin supersonic ground transportation system is known (RU 2252881, B60L 13/10, B60V 3/02, 05/27/2005), selected as a prototype, in which superconducting and super-permanent magnets are installed on the bottom and sides, also on the bottom of the car body a linear engine runner is located, the vehicle’s car is a sealed section articulated with an adjacent sealed section using a hermetically annular bellows, providing limited rotation on the curvature of the track, on both sides of the car Fully sealed windows, and at the joints of sections - hermetically closing the door from the inside, wherein the carriage has apparatus for air purification and regeneration.

The disadvantage of this carriage of the Yansufin supersonic ground transportation system is the low efficiency of the pipeline carriage due to the need to have superconducting and superconstant magnets on board the car’s wagons that increase the car’s mass.

The objective of the utility model is to increase the efficiency of the pipeline car wagon through the use of vortex air flows of the corrugated outer side surface of the wagon wall.

The technical result is achieved by the fact that in the carriage of pipeline transport, containing a sealed enclosure with a linear motor runner located on it, the side surface of the carriage is corrugated.

The proposed embodiment with one wagon of pipeline transport is shown in FIG. 1, in FIG. 2 shows the mechanism of formation of air vortices in the annular groove of the corrugation of the car body.

One or more cars 1 pipeline transport are located in an airtight main pipe 2 (Fig. 1), made, for example, of ferromagnetic material. The runner 3 of the linear motor is located on the body of the car 1. The sealed car 1 can be made in the form of a capsule with a circular cross section. Car body 1 is made of an electrically conductive ferromagnetic material, for example, of low-alloyed high-quality structural steel of the type 09G2, 09G2S, 0KHSND, 17G1S, 16G2AF. On the side surface of the car body 1, there are made ring-shaped grooves 4 with centers lying on the longitudinal axis of the car 1. The set of ring-shaped grooves 4 is a corrugation on the side surface of the car 1.

In FIG. 2 shows one annular groove 4 with the rink formed - a vortex 5 of the incoming air flow 6 on the car 1 moving in an airtight main pipe 2.

The work of pipeline transport is as follows. When the car 1 (Fig. 1) moves in an airtight main pipe 2 along the x axis, part of the incoming air flow 6 (Fig. 2), falling into the annular groove 4, acquires a vortex character and forms an annular roller - vortex 5 (Lavrentiev M.A. , Shabat BV Problems of hydrodynamics and their mathematical models (Moscow: Nauka, 1977, p. 190, 234). On the formed ring-shaped rollers - vortices 5, car 1 rolls relative to the inner wall of the main pipe 2, which, compared with the prototype, where car 1 is sliding, significantly reduces friction losses, which increases the efficiency of pipeline transport.

It should be noted that the resulting vortices 5 carry out stabilization in the space of the moving car 1 in an airtight main pipe 2.

Thus, the formation of ring-shaped rollers - vortices 5 allows to reduce the resistance to movement of the car 1 due to the corrugation of the car body 1 due to the friction of the outer side wall of the car 1 against air in an airtight main pipe 2, i.e. increase the efficiency of the pipeline carriage.
