Description

The invention relates to railway transport and is intended for the transport of people, equipment and various goods.

Known electric train, which contains an electric locomotive and electric cars, to which the contact wire supplies electric energy of direct or alternating current to drive a traction electric motor of direct current and wheel pairs (see Sidorov N.I. How the electric locomotive is arranged and works. - M .: Transport, 1974 . - 224 p.).

The closest analogue is the ER2-A6 contact-battery train, which contains an electric locomotive in which DC traction motors are fed on electrified sections of the railway from a direct current or AC contact network through thyristor valves, and on non-electrified sections of the railway, from alkaline iron -nickel batteries, and trailed cars, under the body of which batteries are placed (see Kalinin V.K. et al. General course of railways. - M.: Transport Ort, 1977 .-- 388 p. and p. 223-224).

Known diesel train, which contains a diesel locomotive with diesel generators, with traction electric motors of direct current, leading to rotation of the wheelset of the diesel locomotive and passenger or freight cars (see Mikhalenko AA Diesel type DR. - M .: Transport, 1990, - 336 p.).

An analogue is a wind turbine generator, which contains a turbine, a gearbox and an electric generator (see Wind Energy. / Ed. By D De Renzo. - M.: Energoatomizdat, 1982. - 272 p.).

The disadvantages of the known electric trains and diesel trains are:

- when transporting people and goods by electric trains over long distances, there is not enough electric power supplied through the same wires, therefore it is required to build substations on the railway sections;

- when 1 kg of diesel fuel is burned, 1.5 kg of oxygen necessary for human life is burned, while a large amount of carbon dioxide, smoke and various harmful substances, for example, lead, are released into the atmosphere, which have a harmful effect on people's health and life expectancy.

The technical result is the creation of an electric train with wind turbine generators, environmentally friendly and safe for people and the environment.

The electric train contains a direct or alternating current contact network, an electric locomotive, direct current traction motors, batteries and cars, characterized in that it is equipped with wind turbine generators, a turbine of one of the wind turbine generators with a diffusion device fixed to the outer shell of the electric locomotive, with a grid installed in the front parts of the specified electric locomotive on the shaft on which the flywheel and the coupling are mounted, which is connected to the shaft of the low speed of the gearbox, the shaft of high frequencies The rotation of the specified gearbox is connected by a coupling to the shaft of the electric generator, which are located in the cavity of the shell of the electric locomotive, wind turbine generators are installed on the roof of each car on welded frames, each wind turbine generator has a turbine with a diffusion device with a grid, a shaft on which the specified turbine and a flywheel are mounted, a gearbox and an electric generator, the shafts of which are connected by couplings, each electric generator is connected to a transformer to reduce the alternating current and convert it to thyristor valves in direct current, with traction DC motors connected to the wheelsets of the electric locomotive and with traction DC motors and wheelsets of the cars, with chargers and batteries located under the body of the car and in the cavity of the shell of the electric locomotive, with tubular electric heating devices located in titans and in boilers for the preparation of boiled water and hot water in the heating network of cars, and with an electrical network for lighting cars, to change the direction of doors An electric train, each electric locomotive with a wind turbogenerator and each car with wind turbogenerators turns on specially equipped turning platforms, or the electric train moves along a railway made along a circle radius or along a curve.
