Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings:

[0020] like Figure 1 to Figure 3 As shown, the present invention is an array type permanent magnet energy collection device, comprising: a non-magnetically conductive elastic end plate 1, a V-shaped rolling track 2, a non-magnetically conductive side wall 3, a coil positioning hole 4, a coil frame 5, an induction coil 6. Screw 7, permanent magnet 8, non-magnetically conductive rolling disc 9, magnetic liquid 10, track groove 11. The permanent magnet 8 array is built in the non-magnetically conductive rolling disc 9 with positioning blind holes as the vibrator of the whole device, relying on the external compound vibration excitation and its own gravity, the vibrator is in the V-shaped rolling track 2 in the two non-magnetically conductive side walls 3 reciprocating motion. The induction coil 6 is wound in the coil frame 5 and is closely attached to the outside of th...

Abstract

The invention discloses an array type permanent magnet energy collection device which comprises a non-magnetic elastic end plate, a non-magnetic rolling disc, a V-shaped rolling track, a non-magnetic side wall with a track groove and a coil positioning hole, an induction coil, a coil frame, magnetic liquid and permanent magnets. Wherein the V-shaped rolling track is installed in the track groove, the permanent magnet array serves as a vibrator in the non-magnetic-conductive rolling disc, and the coil frame wound with the induction coil is fixed to the outer side of the non-magnetic-conductive side wall. The vibrator rolls in the V-shaped rolling track due to external excitation, so that the magnetic flux in the induction coil is changed, and induction voltage is generated. Aiming at swing type vibration, the energy conversion efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the field of vibration energy collection, and is mainly aimed at swinging vibration sources, such as wave vibration, waist vibration of human body movement, and the like. Background technique [0002] The ocean contains endless energy. At present, obtaining electricity from the ocean mainly relies on the establishment of large-scale power stations to convert tidal energy into electricity. In addition to tidal energy, since the vibration of waves on the ocean occurs all the time, electricity can also be output with the help of vibration energy conversion devices. At present, the exploration of the ocean continues to deepen, and the power consumption of various types of sensors and other small electromechanical equipment is getting lower and lower. The traditional chemical battery power supply method has defects in pollution, life and other aspects, which seriously limit the development and utilization of marine resources. There...
