Description
この発明は、波力発電装置に関する。 The present invention relates to a wave power generator.
波力発電装置には、振り子式波力発電装置や水柱振動型波力発電装置などがある。 Wave power generators include pendulum wave power generators and water column vibration type wave power generators.
振り子式波力発電装置は、振り子でシリンダポンプ又はロータリベーンポンプを動かすが、振り子とこれらのポンプ並びに発電機が近接しており、海水による腐食を受けやすい。 A pendulum wave power generator moves a cylinder pump or a rotary vane pump with a pendulum, but the pendulum is close to these pumps and a generator, and is susceptible to corrosion by seawater.
水柱振動型波力発電装置は、波のエネルギーを空気圧のエネルギーに変換するが、空気は圧力が加わると収縮するため、タービンを回す仕事をしないで収縮と膨張を繰り返す一定量の空気が必ず存在し、効率を下げている。 Water column vibration type wave power generator converts wave energy into pneumatic energy, but since air contracts when pressure is applied, there is always a certain amount of air that repeats contraction and expansion without the work of turning the turbine. And lower efficiency.
従来の波力発電装置は、波の周期による出力の変動を十分には除去できない。 The conventional wave power generator cannot sufficiently remove the output fluctuation due to the wave period.
上記の課題を解決するために、本発明の波力発電装置は、オイル槽の中にシリンダを設置し、浮動体の上下とピストン支持棒の上下とを滑車を介して1つの輪となるように繋ぎ、波によって上下する浮動体の運動をピストンに伝え、シリンダからオイルを空気室に送り、空気室から送り出される整流されたオイルによりタービンを回転させる構成とした。 In order to solve the above problems, the wave power generation device of the present invention has a cylinder installed in an oil tank so that the upper and lower sides of the floating body and the upper and lower sides of the piston support rod form a single wheel via a pulley. , The movement of the floating body moving up and down by waves is transmitted to the piston, the oil is sent from the cylinder to the air chamber, and the turbine is rotated by the rectified oil sent out from the air chamber.
本発明の波力発電装置は、波力を受ける部分と発電機を十分離すことができるので、海水による腐食を防ぐ対策が容易である。 Since the wave power generation device of the present invention can sufficiently separate the portion receiving the wave force from the generator, it is easy to take measures to prevent corrosion by seawater.
本発明の波力発電装置は、波のエネルギーを圧力によってはほとんど体積を変化させないオイルの流れのエネルギーに変換するので、水柱振動型波力発電装置におけるようなエネルギーのロスがない。 The wave power generator of the present invention converts the wave energy into oil flow energy that hardly changes in volume depending on pressure, so there is no energy loss as in the water column vibration type wave power generator.
本発明の波力発電装置は、オイルを送り出すシリンダとタービンの間に空気室を設けているが、空気室の容積を十分なものにすれば、波の周期によるオイルの流量のむらを十分に吸収することができる。 In the wave power generation device of the present invention, an air chamber is provided between the cylinder for sending out the oil and the turbine. However, if the volume of the air chamber is sufficient, unevenness in the oil flow rate due to the wave cycle is sufficiently absorbed. can do.
本発明の波力発電装置は、シリンダをオイル槽の中に設置するので、ピストンの滑らかな動きが持続するとともに、海水による腐食を防ぐことができる。 In the wave power generation device of the present invention, since the cylinder is installed in the oil tank, the smooth movement of the piston can be maintained, and corrosion by seawater can be prevented.
以下、本発明の波力発電装置の実施の形態を実施例により説明する。 Hereinafter, embodiments of the wave power generation device of the present invention will be described by way of examples.
図１は本発明の波力発電装置の実施例を示す側面断面図である。 FIG. 1 is a side sectional view showing an embodiment of the wave power generator of the present invention.
波により浮動体１が上下に動くと、浮動体に連結したピストン３がシリンダ２内で上下に動くが、シリンダ２の上下の弁８及び９の働きにより、ピストンが上方に動くときも下方に動くときもシリンダ２内のオイルは空気室４に送られる。シリンダ２から空気室４に送られるオイルの流れにはむらがあるが、空気室４内の空気がクッションの働きをし、空気室４からタービン・発電機５に送られるときにはむらが十分に除去され、安定した発電をすることができる。 When the floating body 1 moves up and down due to the wave, the piston 3 connected to the floating body moves up and down in the cylinder 2, but when the piston moves upward by the action of the upper and lower valves 8 and 9 of the cylinder 2, it moves downward. When moving, the oil in the cylinder 2 is sent to the air chamber 4. The flow of oil sent from the cylinder 2 to the air chamber 4 is uneven, but the air in the air chamber 4 acts as a cushion, and when the air is sent from the air chamber 4 to the turbine / generator 5, the unevenness is sufficiently removed. And stable power generation.
