Development of the new water wheel for preservation of environment and generation of electricity in the river and coast

为了开发利用清洁的自然能源来保护地球环境的机械，人们发明了用于河流和海岸的新型水车。其中一种用于河流的水轮被指定为颤振叶片轮，它的设计使得围绕轮轴布置的几个叶片可以绕每个叶片轴线颤振，从而获得水流中的流体力。该叶片可以通过颤振的方式避免反向电流产生的阻力，从而有效地获得电流功率。在实验室和赛河航道上进行了无油压气机的抽气力和产气量的测量实验，表明了波力轮应用于现场的可能性；设计了波力轮，使受波浪力的板绕悬浮轴摆动，带动压气机与压气机联动。即使是周期为2~5s、波高为15~30 cm的小波，在实验室波浪水槽中安装的车轮所产生的空气量也已达到13 L/分钟。实验结果令人满意，可以为明年的野外研究做好准备。

In order to develop the machinery for the preservation of the earth environment by extracting the clean natural energy, the new water wheels have been invented to use in the river and in the coast. One of the water wheel for the river is designated as the flutter-blade wheel, which is devised such that the several blades arranged around the wheel axis can be fluttered around the each blade axis with getting the fluid force in the water current. This blade can avoid the resistance induced by the reverse current by way of fluttering so as to get the current power efficiently. The experiments to measure the extracting power and the produce air from the oil-free compressor attached to the new wheel have been done in the laboratory and in the waterway from the Sai-river, which has indicated the possibility of applying to the field.The other wheel designated as wave-force wheel is devised such that the plate swinging around the suspending axis with received the wave force can rotate the axis, which drive the compressor linked to the wheel. The volume of the generated air by the wheel settled at the wave tank in the laboratory has reached to 13 L/min in even small waves whose period is 2〜5 sec and wave height 15〜30 cm. The experimental result is so favorable that the field type can be manufactured to advance the field research next year.
