FRONT END WALL SUBMERSIBLE DEPTH ADJUSTING DEVICE FOR COAST FIXED AIR CHAMBER FOR WAVE-POWER POWER GENERATION

PURPOSE:To make a front end wall follow the varying level of water and prevent the loss of a wave energy by providing a door body whose partitioning depth can be varied by the rotation of buoyant moment, in a row, on the front end wall of the captioned air chamber, installing a buoyant body on the door body on said door body, and making said door body rotate according to variation in the level of water. CONSTITUTION:An air chamber 30 is enclosed with a front end wall 31, a rear end wall 32, a ceiling 33, etc., and a generator 34 is installed on the top of the ceiling 33. A door body 60 which is rotatably installed right under the front end wall 31, is formed into a fan shape when viewed sideway, and a circular arc shaped drum plate 6 is installed to a diaphragm plate 5 which is radially provided form the axis and to an arm 7. The arm 7 consists of plural wall members 71-73, and a void tank 9 which serves as a buoyant body and a weight 8 are provided in it. Thereby, when the level of water rises e.g., from W1 to W2, a buoyant force is generated in the void tank 9, causing the arm to rotate counterclockwise, to make the submerging depth d1 of the front end wall 31 substantially the surface of the wall member 71 of the arm 7.
