Description
【発明の詳細な説明】 本発明は、波力発電装置に関する。[Detailed description of the invention] The present invention relates to a wave power generation device.
昨今燃料、即ち化石エネルギーを使用することなく自然
界に存在する太陽光、風力、或いは波力エネルギーを電
気エネルギーに変換して省資源に資する研究が盛んに行
われている。BACKGROUND OF THE INVENTION Recently, much research has been conducted on converting naturally occurring solar, wind, or wave energy into electrical energy without using fuel, that is, fossil energy, thereby contributing to resource conservation.
このうち波力を利用したいわゆる波力発電装置において
は、例えば海主に大規模な構造物筏を浮かべ、多少の波
浪によってはこの構造物筏は揺動しないようにし、且つ
該構造物筏の下部に海面を導入した複数個の空気室を設
け、波浪が生じると前記空気室内の海面がピストン状に
上下動し、これにより生ずる空気流れを利用して直接的
に前記視向に設けたエアタービンを回して発電するよう
に構成されたものがある。Among these, in so-called wave power generation devices that utilize wave power, for example, a large-scale structural raft is floated on the main body of the sea, and this structural raft is prevented from rocking due to some waves, and the structural raft is A plurality of air chambers into which the sea surface is introduced are provided at the bottom, and when waves occur, the sea surface in the air chambers moves up and down like a piston, and the air flow generated by this is used to directly direct the air to the above-mentioned direction. Some are configured to generate electricity by turning a turbine.
しかしながら、斯かる波力発電装置においては、空気室
内の空気を海面が直接圧縮する構造のため、海面の上下

圧力を上げることができず、一方、空気室の圧力を上げ
ると海面はこの圧力により所定の上下動を阻害され、結
局、波力エネルギーを効率よく電気エネルギーに変換す
ることができないという問題がある。However, in such a wave power generation device, since the sea surface directly compresses the air in the air chamber, it is necessary to increase the pressure in the air chamber in order to effectively convert the vertical movement of the sea surface into air flow. On the other hand, if the pressure in the air chamber is increased, this pressure will prevent the sea surface from moving up and down, resulting in the problem that wave energy cannot be efficiently converted into electrical energy.
又、前記空気室の海面上下動時、必ず圧縮相と、吸気相
があるが、圧縮相において生じる流気流れをエアタービ
ンに導入する一方吸気相において外気を吸入するための
制御を各空気室毎に行ねわけならず、このなめ膨大な製
造コストがかかるという問題もある。Also, when the air chamber moves up and down at sea level, there is always a compression phase and an intake phase, and while the air flow generated in the compression phase is introduced into the air turbine, each air chamber is controlled to suck in outside air during the intake phase. There is also the problem that it cannot be done every time, and that this process requires a huge amount of manufacturing cost.

適宜の支持手段(図示略)によりガイドされている。In FIG. 2, the rotation of the shaft (3a) of each swing arm (3) is converted by a motion conversion mechanism αe into a reciprocating motion of a piston 02 of an air compression cylinder αD corresponding to each swing arm (3). . To do this, for example, a pinion gear 03 is fixed to the end of the shaft (3a) extending into the container (1), and a rack α9 that moves integrally with the four rods 04 of the piston 02 is meshed with the pinion gear 03. The rack (2) is guided by appropriate support means (not shown) so that it can reciprocate in the direction of movement of the piston 02.
