ン(5)や発電機(6)の設計が困峨となり、洲価なも
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

ネルギー変換装置を提供することを目的としている。This invention was developed in order to eliminate the hot spots of the conventional ones as described above76, and it is a wave energy conversion device that makes the energy of the generated air flow uniform regardless of the height of the waves. is intended to provide.

形成されている。FIG. 2 is a sectional view of one embodiment of the present invention, and FIG. 3 is a partially enlarged perspective view of the front end plate (9b), which is the main part.
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.
穴aりは、下部はど数が多いので、波浪が大き(なるほ
ど変換効率が低下するので、波浪の大きさが変っても空
気流として堆り出されるエネルギーは平均化され、従来
のものより変動の少ないものになる。Since there are many holes at the bottom of the holes, the waves are large (I see, the conversion efficiency decreases, so even if the size of the waves changes, the energy released as airflow is averaged out, making it more efficient than the conventional one) It becomes less volatile.
従って、タービン(5)に供給される空気流のエネルギ
ー変化は少なくなり、その設、frが容易となる。Therefore, the energy change of the airflow supplied to the turbine (5) is reduced, and its installation and fr are facilitated.

However, the same effect can be achieved even if the hole is made triangular as shown in Figure 4.
以上のようVClこの発明によれば、波浪の大きさに対

で、変換されるエネルギーの変動が少14 (/jり。As described above, according to this invention, the number of holes below the front end plate (9k) is large enough to accommodate the size of the waves, so the fluctuations in the converted energy are small.
