Use of security light at fish farms

Issues before installation

The fixed propeller turbine had a shape that made it easy to install the turbine at the opening of the fish farm, but the use of the generated electricity was not clearly determined. The biggest problem is that when installing such a fixed propeller turbine outdoors such as a fish farm, there is a risk that it will take a huge amount of time and effort to take measures against dust.

Installation purpose

Use it as a power source for security lights and check the driving issues of fixed propeller turbines in the natural environment.

Benefits of Introduction

It was possible to effectively use it as electric power for water that is constantly flowing. In addition, it became clear that it would take a huge amount of time and effort to take measures against dust on the fixed propeller turbine. This demonstration experiment revealed that it is easier to take measures against dust from open-type diversion turbines than other methods, and open-type diversion turbines turned to be effective when installed in places that flow under the natural environment such as agricultural canals.
