る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a device for adjusting the submersion depth of a front end wall in an air chamber for fixed coastal wave power generation. In particular, the present invention relates to a submersion depth adjustment device suitable for cases where the water level difference is large.

ｄ’ ／ Ｄが大きくなると波長の長短にかかわらず波
エネルギー交換効率の低下が著しい。In general, coastal fixed wave power generation devices are used when the water level rises or
Alternatively, if the submerged depth of the front end wall in the coastal fixed air chamber for wave power generation is d, and the water depth at the front end wall installation location is D,
When d'/D becomes large, the wave energy exchange efficiency decreases significantly regardless of the length of the wavelength.
従って、沿岸固定式波力発電用空気室における前端壁の
水没深さは出来るだけ浅くすることが望ましい。Therefore, it is desirable that the depth of submersion of the front end wall of the air chamber for fixed-shore wave power generation be as shallow as possible.

エネルギーの損失を招く欠点があった。However, in coastal fixed wave power generation devices, the depth of submersion of the front end wall in the air chamber is shallow (if installed, the water surface may be affected by fluctuations in tide level, incidence of large wave heights, HaVesat down phenomenon, and surf beats). When the water level drops significantly, the water level separates from the front end wall of the air chamber, resulting in loss of wind wave energy.

考え方は有ったが水没部を変化させる駆り１装置のため
のエネルギー損失や駆動機器の耐久性、摺動部の海水中
での潤滑方式、水気密性に問題があった。In order to prevent the above losses, there was an idea to change the submerged part of the front end wall, but changing the submerged part requires energy loss for the driving device, durability of drive equipment, and lubrication of sliding parts in seawater. There were problems with the method and watertightness.
そこで、本発明は水面の変化に合セで前端壁の水没深さ
を駆動力の供給なく水面の変化に追随させながら水気密

招く忌れがない。As described above, the present invention maintains watertightness by using an oil-free lubrication method with a seawater lubricant to maintain a door body having a certain submersion depth d against the front end wall of an air chamber for coastal fixed wave power generation. Since it is arranged so that it can slide freely, it can prevent the wave set down phenomenon from occurring due to changes in the tide level or when large wave heights occur.
Also, when the water level drops significantly, such as when a surf beat occurs, the water level does not separate from the front end wall of the air chamber.
In addition, the watertightness of the sliding parts can be maintained and there is no risk of loss of wave energy.
従って、波高の変動が大きいために設置できなかった場
所にも設置できるようになる。Therefore, it becomes possible to install it in places where it could not be installed due to large fluctuations in wave height.
