底を照射することができる。(Prior art) For example, as shown in the side view of Fig. 3, a solar light introduction device used for an underwater greening system connects a floating support platform 2 underwater via a chain 1 anchored to a sinker on the seabed. The sunlight is reflected by the solar tracking type reflector 114 attached to the upper end of the sunlight introducing cylinder 3, which is vertically moored to the support base 2 and whose upper end protrudes above the sea surface. 3, as shown in Figure 4,
The light can be diffused through a diffusion lens 5 and a lens protection transparent plate 6 attached to the lower end of the body via an annular fitting 7 to illuminate seawater and the seabed.

至る。According to this method of introducing sunlight, by introducing sunlight near the ocean floor, it is possible to foster the growth of marine life in the sea and on the ocean floor.
．． Lens protection transparent plate 6. Marine microorganisms adhere to the mounting fittings 7 and the like, grow and flourish, and obstruct sunlight from entering the seabed.
そこで、従来は時折り、ダイパーによる潜水作業で機械

係部材の損傷の惧れもある。Therefore, in the past, it was sometimes necessary to mechanically remove attached organisms by diving with a dipper, which not only incurs considerable costs, but also poses a risk of personal injury and requires the use of tools to remove marine organisms. There is also a risk of damage to related parts such as plates.
本発明はこのような事情に鑑みて提案されたもので、ダ

金属部には海洋生物は付着しなくなる。With this configuration, an underwater current flows with the anode conductor as the anode and the lower end of the sunlight introducing tube as the cathode, and a large amount of hypochlorite ions are generated near the annular anode conductor due to seawater electrolysis. As a result, marine organisms no longer adhere to the non-metallic part of the lower end of the sunlight introduction tube.
