Abstract

A trough used for feeding power to a traveling body in a noncontact manner, a paved structure, and a method of constructing the paved structure. The trough used for a paved structure feeding power to a power receiver provided in a traveling body through an electromagnetic wave, includes: a trough body having a trough depression extending in the direction in which the traveling body runs; a magnetic member laid in the trough depression; a power feeding body laid on the magnetic member to feed power to the power receiver through an electromagnetic wave; and a power feeding body protector laid in the trough depression to cover the power feeding body.

Claims

1. A trough used for a paved structure feeding power to a power receiver provided in a traveling body through an electromagnetic wave, comprising:

a trough body having a trough depression extending in the direction in which the traveling body runs;

a magnetic member laid in the trough depression so that a flat upper surface is formed;

a power feeding body laid on the upper surface of the magnetic member to feed power to the power receiver through an electromagnetic wave; and

a power feeding body protector laid in the trough depression to cover the power feeding body, wherein

the trough body has a partition formed in the center of the trough depression to form two grooves in the trough depression,

the partition is formed from a plurality of protrusions aligned to form a plurality of spaces connecting the two grooves with each other, and

the power feeding body has a coiled conductor laid in any two of the plurality of spaces and in the two grooves.

2. The trough according to claim 1, wherein the trough body contains aggregate formed of stainless, aluminum, or combination thereof and a concrete covering the aggregate.

3. The trough according to claim 1, wherein the magnetic member contains slag.

4. The trough according to claim 1, further comprising:

a visible part visible from the traveling body, wherein

the visible part is provided on the upper surface of the power feeding body protector over the power feeding body.

5. The trough according to claim 4, wherein the visible part is colored in a color different from that of the power feeding body protector.

6. The trough according to claim 4, wherein the visible part is formed of a retro reflective material.

7. A paved structure feeding power to a power receiver provided in a traveling body through an electromagnetic wave, comprising:

a cutting part extending in the direction in which the traveling body runs; and

a plurality of troughs according to claim 1 laid in the cutting part.

8. A method of constructing the paved structure according to claim 7, comprising the steps of:

forming a depression in the paved structure;

laying a plurality of troughs in the cutting part; and

electrically connecting the plurality of troughs with each other.
