The present invention relates to a turbine, and more particularly to a turbine for converting one-way flow energy of the fluid, such as wind, running water, etc. into electrical energy.

In general, a turbine refers to a machine or device that converts the energy of a fluid such as water, gas, steam, etc. into useful mechanical work. In particular, a turbine related to the technical field of the present invention relates to an apparatus for converting flow energy of a fluid such as wind, running water, etc. into electrical energy.

Referring to FIG. 9, when a fluid such as wind or running water flows from left to right, the turbine is left in the flow direction and the drag plate touches the drag plate support member to generate a large drag, that is, a large torque, while the right side supports the drag plate. The member does not play a role, and the drag plate is parallel to the flow, resulting in a streamlined shape. In addition, the drag plate installed at different angles for each floor acts continuously to generate uniform torque and rotation. In this case, although divided into a limited number of layers, it is possible to generate a more uniform torque and rotation by forming a plurality of closely arranged.

Referring to FIG. 10, when the linear velocity in the outer drag plate is greater than the fluid velocity, the outer drag plate is opened and the resistive force acting on the remaining plates acts as the rotational force. If one drag plate is used, the outside of the drag plate will generate a negative torque, and the inside of the drag plate will generate a positive torque, which can be disadvantageous as a whole.

As described above, the turbine of the present invention has a streamlined blade and a drag plate to rotate in one direction by the flow of the fluid, such as wind, running water, etc., the maximum resistance in the portion that rotates in the same direction as the flow direction of the fluid In the part that is generated and rotated in the opposite direction to the flow direction of the fluid, a minimum resistance can be generated to provide the maximum output as a whole. In addition, the turbine of the present invention uses a plurality of drag plates on each blade, and each drag plate is automatically angled to various flow variables such as the flow direction and size of the fluid, thereby providing uniform torque and rotation. have.
