Description

  The present invention relates to a vibration power generation apparatus that generates power using vibration of an object.

  Various power generation methods have been developed. In recent years, the movement to use natural energy has accelerated, and various power generation methods using wave power, which is one of ocean energy, have been proposed. In the early days, a method in which a generator is rotated via a turbine with air compressed by wave force has been adopted, but there is a drawback that the apparatus is huge and expensive.

Therefore, a method using a linear generator capable of direct drive from wave power has been proposed instead of a method of rotating an existing generator with wave power. As an example, a method of driving a linear generator solid in the sea with a floating body on the sea surface (hereinafter referred to as “Patent Document 1”) has been proposed.
Further, a method of driving a linear generator fixed on the coast with a floating body on the sea surface (hereinafter referred to as “Patent Document 2”) has been proposed.

  However, in the method of Patent Document 1, since the linear generator is fixed in the sea, there is a problem that maintenance of the generator body must be performed in the sea. Further, in the method of Patent Document 2, although the maintenance of the generator main body can be performed on land, there is a problem that the installation of the floating body as an energy source is limited to the sea near the coast.
