この発明は波力エネルギー変換装置、′＃に海などの彼
方エネルギーを空気エネルギーに変換し。[Detailed Description of the Invention] [Industrial Application Field] This invention is a wave energy conversion device, which converts energy beyond the ocean, etc., into air energy.
動力や熱などを取り出すようにした泊岸固定形の波力エ
ネルギー変換装置に関するものでめる。Contains information on wave energy conversion devices fixed to the shore that extract power, heat, etc.
従来、この種の装置として第４図に示すものがめった１

である。（５）は上記チャンバーの水面上に位置する部
分に設けられた第２の開口部で。Conventionally, as this type of device, the one shown in Figure 4 has rarely been used.
, In this figure, (1) is the quay, (21 is the seabed, (3)
(4) is a robust chamber firmly fixed to the quay wall and the seabed, and (4) is an opening provided in the underwater portion of the chamber for introducing wave energy. (5) is a second opening provided in a portion of the chamber located above the water surface.
波の到来に応じて空気流が出入するためのものでるる。This is for airflow to move in and out depending on the arrival of waves.
（６１は空気ダクトで、一端が上記第２の開口部（５）

The other end is open to the atmosphere.

（４）を通ってチャンバー（３）内の海水に伝達され。In such a configuration, waves (9) come one after another from a distance toward chamber (3), causing chamber 1
Upon reaching the front surface of 31, the energy of the wave (9) is transferred through the opening (4) to the seawater in the chamber (3).
チャンバー（３）内の海水面ａ〔が上下に振動する。The seawater level a inside the chamber (3) vibrates up and down.
この時、チャンバー（３）内における海水面（１（ｌの
上部の空間αＢの空気は圧縮、膨張を繰り返すので。At this time, the air in the space αB above the sea level (1(l) in the chamber (3) is repeatedly compressed and expanded.

エネルギーを空気の流れのエネルギーに変換するときの
効率（チャンバー（３）の変換効率）は。An air flow is generated within the air duct (61). This air flow rotates the air turbine (7), which drives the generator (8) connected to it to generate electricity. Wave energy is transferred to the air What is the efficiency (conversion efficiency of chamber (3)) when converting into flow energy?
チャンバー（３）に入射する波の波長（入射波の波長）
Ｌと、チャンバー＋３１の奥行寸法Ａとに関係する０第
５図はチャンバー（３）の変換効率と〜１との関係を示
す特性図でめり、この図から明らかなように。Wavelength of wave incident on chamber (3) (wavelength of incident wave)
As is clear from this figure, FIG. 5 is a characteristic diagram showing the relationship between the conversion efficiency of the chamber (3) and the conversion efficiency of the chamber (3).
変換効率はり１が特定の値の時に最大（最適）となる。The conversion efficiency scale 1 becomes maximum (optimal) when it is a specific value.
この特定の値は０，１〜０．１５程度の値でめり。This specific value is approximately 0.1 to 0.15.
この値から外れろと変換効率は急激に低下する。When the value deviates from this value, the conversion efficiency decreases rapidly.
この理由は次のように考えられている。即ち波長りが最
適値より長すぎると、波力エネルギーの一部しか変換で
きないためであり、又、波長りが最適値より短かすぎる
とチャンバー（３）に波が生じてチャンバー内の河水面
ｉｌｌが一様に昇降せず、空気の圧縮、＃脹が有効に行
なわれないためである。The reason for this is thought to be as follows. In other words, if the wavelength is too long than the optimum value, only a part of the wave energy can be converted, and if the wavelength is too short than the optimum value, waves will be generated in the chamber (3) and the river water surface inside the chamber will be damaged. This is because the ill does not move up and down uniformly, and air compression and expansion cannot be performed effectively.
波長りが長すぎる場合には、波力エネルギーが大きいの
で変換効率が小さくなっても問題がないが、波長りが短
かすぎると波力エネルギーが小さく、かつ変換効率が小
さいため最終的に利用できるエネルギーは非常に少くな
り実用上大きな問題となる。If the wavelength is too long, the wave energy is large, so there is no problem even if the conversion efficiency is low, but if the wavelength is too short, the wave energy is small and the conversion efficiency is low, so it is difficult to use in the final stage. The amount of energy that can be produced is extremely small, which poses a major practical problem.

ないという欠点がめった。[Problems to be solved by the invention] When actually installing a wave energy conversion device, the value of the depth dimension A of the chamber must be set to be optimal for the wavelengths that occur frequently at the installation location. Decide. However, since waves generated in actual ocean waters have various wavelengths, conventional wave energy conversion devices often have the disadvantage that they cannot continuously generate power with high efficiency.
そこで波長に合わせてチャンバーの奥行寸法Ａを変化さ
せる案も考えられるが、Ｓという非常に厳しい環境での
使用を考えるとこの案は実用的ではない。Therefore, a plan may be considered to change the depth dimension A of the chamber according to the wavelength, but this plan is not practical when considering the use in the extremely harsh environment of S.

にしたものでるる。This invention was made in order to eliminate the above-mentioned drawbacks of conventional devices, and aims to provide a wave energy conversion device with high energy conversion efficiency for wavelengths shorter than the optimum wavelength of 1%. O [Problem yal - Means for Solving] In this invention, at least two chambers are arranged in the direction of arrival of waves, and an opening/closing device is provided in the chamber located in front of the arrival of waves. , the chamber can be communicated with the atmosphere.

ンを効率よく回転することが出来るものである。[Function] When the wavelength of the waves is short, when the opening/closing device of the front chamber is opened, the water level in the front chamber moves up and down freely, but the space above the water surface does not compress or expand, so the apparent front The situation is the same as if the chamber had disappeared. In other words, since only the rear chamber acts, the same effect as when the depth dimension of the chamber is shortened is produced, and the air turbine can be rotated efficiently.

きの半分となり高効率を維持することが出来なくなる。The conversion efficiency characteristics in this case are shown in FIG. In this figure, the dotted lines correspond to the conventional characteristics shown in FIG. 5, and the solid lines represent the characteristics of the present invention. As mentioned above, when the switchgear is opened when the wavelength of the wave is short, even though the depth of the chamber is large, the efficiency is close to the maximum efficiency of the conventional method because the effect is equivalent to that of a chamber with a small depth. It can be maintained in a wide wavelength range and the air turbine (71X72) can be rotated efficiently. In addition, if the opening/closing device fi31 is closed when the wavelength is short, the water surface in each of the first and second chambers (10
1) (IC2) moves up and down together to connect the first and second ducts (6
1) Although the airflow is sent to each of (62), the energy of both the first and second air turbines is half of that when the switchgear is opened, making it impossible to maintain high efficiency.
