Description

[Detailed description of the invention] The present invention relates to a power generation device, and more specifically to a power generation device for making an object (magnetic material) move up and down by utilizing the non-magnetic property of the center point of the magnetic pole of a permanent magnet. This will be explained in more detail below.

In the figure, 1, 1, . . . are permanent magnets, which are arranged at equal intervals on the same circumference so that the inner magnetic poles are the same. Although eight permanent magnets 1 are used in the illustrated embodiment, the present invention is not limited to this, and the number can be selected as appropriate.

2, 2, . . . are magnetic bodies fixedly installed inside each of the permanent magnets 1. A permanent magnet 3 is rotated inside the permanent magnet group with a rotating shaft 4, and is fixed to the rotating shaft 4 so that the outer magnetic pole is different from the inner magnetic pole of the permanent magnet group. The permanent magnet 3 is rotated around a rotating shaft 4 so as to face each permanent magnet 1 of the permanent magnet group in sequence. Reference numeral 5 denotes an adjustment weight provided on the opposite side of the rotating shaft 4 to the permanent magnet 3. 6
is a magnetic body disposed below each of the magnetic bodies 2, 2, . . . in a vertically movable manner.

Next, the mode of operation of the present invention having the above configuration will be explained.

When the outer magnetic pole of the permanent magnet 3 and the inner magnetic pole of the permanent magnet 1 face each other at the position shown by the solid line in FIG. Since the force has disappeared, the magnetic body 6 placed below falls due to its own weight (Fig. 3B), and the permanent magnet 3 rotates further until its outer magnetic pole is permanently at the position of the imaginary line. When the magnetic body 6 moves to a position away from the magnet 1, it is again attracted to the lower end of the magnetic body 2 and rises (FIG. 3C). Therefore, by rotating the permanent magnet 3, the magnetic body 6 can be caused to move up and down. If a large number of permanent magnets 1 are arranged as in the present invention, a large number of magnetic bodies 6 can be sequentially moved up and down.

Since the present invention has the above-described structure and operation, it is possible to make an object (magnetic material) move up and down by utilizing the non-magnetic property of the center point of the magnetic pole of the permanent magnet. In addition, since it is composed only of permanent magnets, it has few failures and is easy to manufacture, making it highly effective in practical use.
