Description

The invention relates to the construction of an electric current generator, mainly intended for railway, tram transport or for the subway.

Known power generating device on a rail track according to the patent of the Russian Federation for invention No. 2095265, IPC B61L 1/04, publ. November 10, 1997

The essence of the invention lies in the location of the piezoelectric transducer of mechanical pressure in the electric potential difference on the railway track, the transmission of the wheels of the railway train to it from the rails and obtaining the electric potential difference, the piezoelectric transducer of mechanical pressure in the electric potential difference is placed on the support between the sleepers.

In addition, a piezoelectric transducer of mechanical pressure to the difference in electric potentials is located between the rails and the pressure on it is transmitted from the rails by a lever-console system.

Disadvantages: the complexity of the design and the high complexity of placing the generator on rails.

Known power generating device according to the patent of the Russian Federation for invention No. 2535960, IPC ЕВВ 2/00, publ. 12/20/2014, the prototype.

This device is part of the rail track device, containing two half ties that are rigidly connected by a coupler and made of composite material on which the rails are fixed; half ties are equipped with electric generators that are sealed under rails and have electrical contacts connected by current conductors located in central holes made in couplers along the ties their longitudinal axis, and forming an electric circuit connected to the electric power supply system of the paths, while the generators are made of texture ovannoy nanoscale piezoceramics on the one polarization axis, vertically and coaxially disposed whose polarization axis generators.

Thus, when rolling stock passes along a section of a rail track in electric generators, an internal voltage is created under the influence of the weight of the cars, which leads to the generation of electricity, which is added up and transmitted to the control and supply system of the rolling stock.

Disadvantages:

- design complexity

- the need to remodel existing railways, which is associated with huge material and labor costs,

- weakening of sleepers when they are cut.

The objective of the invention: to simplify the installation of an electric generating device on a rail track without finalizing its design.

Achieved technical result: simplification of installation of an electric generating device on a rail track of any type and in any place.

The solution of these problems was achieved in an electric generating device containing an electric generator mounted on a rail using a mounting unit, in that the electric generator contains a sealed housing, in the cavity of which a toroidal magnetic circuit is installed, having a gap and an excitation winding, a pusher is mounted on the outside of the housing using an axis using an axis T-shaped, having three levers: the first is designed to contact with the wheels of the transport, the second is spring-loaded, and the third is made of a magnetic core with NOSTA introduction into the gap and an exit from it.

As the attachment point, a clamp can be applied attached to the side wall of the housing and intended for fastening to the rail.

The clamp can be made in the form of two bolts with clamping bars and nuts.

The invention is illustrated in the drawings of figures 1-8, where:

- in FIG. 1 shows the main view of the device, side view

- in FIG. 2 shows a top view,

- in FIG. 3 shows the appearance from the end,

- in FIG. 4 shows the appearance in isometry,

- in FIG. 5 shows a side view in partial section,

- in FIG. 6 shows the top view,

- in FIG. 7 shows a diagram of the interaction of a wheel of a railway pair with a device, end view,

- in FIG. 8 shows a diagram of the interaction of the wheels of a railway pair with the device, view along the railway.

The device comprises (Fig. 1): an electric generator 1 having a sealed housing 2 and a toroidal magnetic circuit 3 located therein. A gap 4 is made in the toroidal magnetic circuit 3. An excitation coil 5 is fixed on the toroidal magnetic circuit 3.

Outside of the sealed housing 2, a pusher 8 of a “T” -shaped form, having three integral levers made at the same time, is mounted on the bracket 6 using the axis 7: the first lever 9 is designed to contact the transport wheels, the second lever 10 is spring-loaded with a spring 11, and on the third lever 12 made magnetic core 13 with the possibility of introducing into the gap 4 and output from it.

The magnetic core 13 has a magnetization perpendicular to the direction of motion.

The magnetic core 13 periodically closes and opens the working gap 4 of the toroidal magnetic core 3, making a reciprocating motion when the vehicle is moving.

The device can be attached with a clamp 14 (which is an integral, structural part of the housing) to the bottom of the rail 15 (Fig. 8). The rail 15 is installed on the sleepers 16 (Fig. 7 and 8).

The clamp 14 can be attached to the side wall 17 of the housing 2 and contain two bolts 18 with straps 19 and nuts 20 (Fig. 2 and 6).

The force for driving the electric generator 1 is created by the wheels 21 of the railway pair 22 (Fig. 7 and 8) when the vehicle is moving.

Operating principle.

The generator 1 using the clamp 14 is installed on the rail 15 (Fig. 7).

Wheel 21 of the railway pair 22 (FIGS. 1 and 8), colliding with the first lever 9, rotates the pusher 8 around the axis 7, forcing the third lever 12 to move towards the working gap 4 of the toroidal magnetic circuit 3, leading the third lever 12 into the working gap 4, closing toroidal magnetic circuit 3. With the further movement of the wheel 21, the spring 11 returns the entire system to its original position, and so with each passage of the next wheel 21.

During the reciprocating movement of the third lever 12, the magnetic core 13 is periodically inserted and removed from the working gap 4 of the toroidal magnetic core 3. The magnetic flux, increasing and decreasing, induces electric pulses that are transmitted through the converter (not shown) to the battery (in the drawings not specified).

The application of the invention allowed:

to simplify the design of the electric generator,

- to simplify the installation of the electric generator on rail tracks,

- eliminate the need to remodel existing railways,

- to eliminate the weakening of sleepers when they are cut.
