A concrete foundation that was made to support conventional hydroelectric generators was abolished, and a turbine, gearbox, power transmission shaft, and generator were integrally attached to a lightweight support base. Just put it in to work. To make installation and removal easy, we made it as lightweight and compact as possible. By using abundant water locally, the position of the hydroelectric generator at the bottom of the river is not changed.

A wind turbine replaced with a water turbine, a speed increasing device for increasing the rotational speed of the wind turbine, a generator for generating power by the rotational force increased by the speed increasing device, and a support base for supporting these are provided. Wind power generators that can be used. It can be used for both hydroelectric and wind power generators.

  Since the present invention is configured as described above, the following effects can be obtained.

  Easy to transport, install and remove.

  Since the conventional support base is required to be firmly fixed, the material thereof is limited to a highly rigid metal material or reinforced concrete. However, in the present invention, since the support base needs to be light, FRP and plastic materials can be used, and the range of material selection is widened.

  Conventionally, a fixed hydroelectric power generation apparatus needs a water release channel when water increases. This device can be easily withdrawn when the river rises, avoiding driftwood and earth and sand disasters. Small and medium rivers are prone to flooding. If a water turbine is permanently installed, it becomes an obstacle during a disaster.

  The position of the hydroelectric generator can be moved easily and can be easily adjusted so that the water flow is optimally applied to the turbine blades. The output can be easily adjusted by adjusting the amount of water flow on the turbine blade. By moving the water wheel up and down, the speed of water acting on the water wheel blades can be changed and the number of rotations can be adjusted. Since the main body of the conventional water wheel is firmly fixed, the output adjustment needs to control the water flow. The apparatus of the present invention can easily adjust the output by moving the position of the water turbine while keeping the water flow as it is.

  Normally, agricultural waterways and the like have water rights, and it is difficult to install hydroelectric generators with fixed facilities. Portable hydroelectric generators can be easily installed when needed, and are easy to withdraw, making it easy for water owners to agree to installation.

  When camping in the mountains, it is possible to generate electricity by using a nearby mountain stream, and it does not give an environmental burden compared to using fossil fuel.

Even in a narrow place where a vehicle cannot enter, it can be easily carried and transported by hand only, so it is useful for power sources such as camping. In addition, the emergency power supply at the time of disaster is particularly effective because it does not require fuel supply. Industrial value is high because it can be assembled in a short time and operated without construction. To experience learning about natural energy and power generation at school, the power generation device can be easily brought into a delicate field, and since the device is small and light, it is very easy to understand. Because it is low drop and rotation is slow and safety can be secured, you can touch it with your hands and experience learning. In addition, as a power source for measuring equipment for field experiments and observations at universities and research institutions, it is possible to secure a power source with unlimited operation time in places where it is difficult to secure a power source. Compared to other natural energy, water has less fluctuation in supply and it is easy to secure a stable power source.
