Abstract

PURPOSE:To reduce the variation in the pneumatic energy by providing many pores at a front end plate which form an air chamber for converting wave force into pneumatic energy in such a manner that more pores are formed toward the downward direction of the plate, thereby varying the energy conversion efficiency in response to the magnitude of the waves. CONSTITUTION:When waves 1 elevationally move, water surface level 4 in an air chamber 3 formed of a structure 2 such as a breakwater, an upper plate 9a supported to the structure 2, and a front end plate 9b elevationally moves upwards or downwards, thereby producing an air stream 8. Then, a turbine 5 is rotated by the air stream 8, a generator 6 is rotated to generate electric power. In this case, pores 10 are formed at the plate 9b in such a manner that more pores are formed toward the downward direction lower than the average line of the water surface level 4. Thus, when the waves 1 are small, the waves 1 are introduced through the pores 10 into the chamber 3 to enhance the conversion efficiency of the wave force energy, and when the waves 1 are large, the air stream 8 is led out through the pores 10 when the level 4 is decreased lower than the pores 10, thereby decreasing the conversion efficiency.

のになるという欠点があった。Since the conventional device for converting wave energy into energy, etc., has the VC configuration as described above, the front end plate (9b) of the air chamber (3) interferes when the wave height is small. This suppresses the vertical movement of the water surface (4) and reduces the conversion efficiency. On the other hand, when the height of the waves is large, the front end plate (9b
) does not become an obstacle, improving conversion efficiency. Therefore, the difference in the energy of the airflow (8J) when the wave height is small and when it is large is very large, which makes the design of the turbine (5) and generator (6) difficult, and It had the disadvantage of becoming

Jil’il! The holes are drilled in the iJ4 board (9b) and are formed below the average water level (river) indicated by the broken line as shown in the figure, and the number of holes increases as you go lower.

In this case, when the waves are small, the waves (1) enter the air chamber (3) through the hole u1 and raise and lower the water surface (4), so the conversion efficiency of the wave crab inertia is improved compared to the conventional one. do. However, when the waves are large, the water surface (4) in the air chamber (32) rises and falls significantly, and when the water surface (41 falls below the position where holes U and +3 are provided), air leaks, and the wave force Energy conversion efficiency decreases.
