Embodiment

[0022] Figure 1 ~ Figure 3 An electromagnetic vibration energy harvesting device is presented.

[0023] The device in the embodiment includes an upper shell 1, which is closely connected with the lower shell 6 through six screws 11, and the axes of the upper shell 1 and the lower shell 6 overlap to form a complete spherical shell. There is a support column 2 inside the upper shell 1, and the axis of the support column 2 overlaps with the axis of the upper shell 1 .

[0024] The support column 2 is connected with the TBS joint bearing 4 through the threaded hole 3 , and the TBS joint bearing 4 is connected with the hemisphere 10 through the threaded hole 5 . The hemisphere 10 is made of metal, preferably iron alloy, on which several permanent magnets 8 for power generation are distributed. The ball 10 can rotate in various directions around the center of the ball.

[0025] Several coil post holes 13 are distributed on the lower casing 6 . Two grooves 12 are symmetrically d...

Abstract

The invention discloses an electromagnetic vibration energy collecting device for an ocean robot. The device comprises a hemispherical body. Permanent magnets are distributed on the surface of the hemispherical body; the hemispherical body is positioned in a lower hemispherical housing, and sphere centers of the two are same; round holes corresponding to the permanent magnets on the surface of thehemispherical body are distributed in the lower hemispherical housing, and coil columns are inserted into the round holes; the lower hemispherical housing and an upper hemispherical housing are connected to form a complete spherical housing; a supporting column is supported in the upper hemispherical housing towards the sphere center, and the supporting column is connected with the hemisphericalbody through a TBS knuckle bearing, so that the hemispherical body can rotate in any direction around the steel ball center of the TBS knuckle bearing; the magnetic poles of the outward parts of the adjacent permanent magnets on the hemispherical body are opposite; and the winding directions of coils wound on the adjacent coil columns are opposite. Energy of external objects in all directions canbe directly collected and converted into electric energy; and the overall structure is stable, the shape is symmetrical, and the influence on external device stability is small.

Description

technical field [0001] The invention relates to the technical field of vibration energy collection, in particular to an electromagnetic energy collection device for converting wave energy into electric energy. Background technique [0002] At present, marine robots have higher and higher requirements for energy in their operations, and pure battery energy storage cannot meet the operational needs. At present, some researchers have designed and manufactured power generation devices for marine robots. Generally speaking, these devices are divided into two categories: one is a resonant power generation device, and the other is a rotary power generation device. For the above two devices, Faraday's law of electromagnetic induction is used to generate electricity. Among them, the structure of the resonant power generation device is the simplest, usually the direction of motion is a straight line, and the design is easy, but this also leads to the fact that the power generation de...
