Abstract

The present invention is a platform (20) that performs non-contact power supply using a pair of coils (5) that can be placed opposite to each other between an underwater mobile body (10) that can move relatively. A recess (30) for accommodating at least a part of the underwater mobile body (10) across a gap; a pair of first coils (5A) that can face each other is formed on one wall side of the facing walls (31) of the recess (30) The coil (21); and the coil (21) forming a second coil pair (5B) that can face each other on the other wall portion side of the facing wall portion (31) of the concave portion (30).

Description

technical field [0001] The invention relates to a power transmitting device, a power receiving device and a non-contact power supply system. This application claims priority based on Japanese Patent Application No. 2014-117710 filed in Japan on June 6, 2014 and Japanese Patent Application No. 2014-129347 filed in Japan on June 24, 2014, the contents of which are incorporated herein. Background technique [0002] For example, in equipment that operates underwater, it is difficult to use an internal combustion engine and lay wires. Therefore, electric power contained in a storage battery is generally used as a power source. As a non-contact power supply system for charging a storage battery underwater, a proposal shown in Patent Document 1 below has been proposed. [0003] In such a contactless power feeding system, when the distance between the power receiving coil and the power transmitting coil increases, power feeding efficiency decreases (see Patent Document 2). Therefo...
