It is about the system.

In general, the power generating device generates electricity in such a manner that an induced current is generated using a rotational force.

In the case of a large power generation apparatus, kinetic energy in which a fluid flows along a constant flow path is converted into rotational force through a turbine, and a method of rotating a rotor connected to a turbine and a rotating shaft is widely used.

In one embodiment of the present invention, the flow path formed in the inner space of the housing 100 may have a cylindrical shape lying on the basis of FIG.

The nozzle assembly 400 is fixedly coupled to the housing 100 on the flow path of the inner space of the housing 100, is disposed at a position adjacent to the inlet 110, and a working fluid is introduced through the inlet 110. A plurality of nozzle blades 410 may be provided at positions corresponding to the plurality of nozzle blades 410.

The inlet 110 may be provided such that the working fluid is introduced into the inner space of the housing 100 through the circular space, and the nozzle blade 410 is disposed at a position corresponding to the circular space into which the working fluid is introduced. It may be operated to divert the flow velocity and the flowing direction of the working fluid.

The nozzle assembly 400 may be formed in a short cylindrical shape, and the direction of flow may be changed by an angle at which the inflow working fluid is disposed and the interval of the nozzle blade 410.

This is as shown in Figure 3, the nozzle blades 410 consisting of a plurality of blades are arranged at regular intervals, respectively, in a space corresponding to the inlet 110 through which the working fluid is introduced, can be arranged inclined in one direction. .

The flow velocity of the working fluid is determined through the intervals of the nozzle blades 410, and the flow direction of the working fluid is changed through the angle at which the nozzle blades 410 are inclined.

The turbine 200 is disposed after the nozzle assembly 400, and the working fluid via the nozzle blade 410 is provided to directly interfere with the turbine blade 210.

Specifically, the inlet 110 is formed in an annular shape, the working fluid is introduced into the interior of the housing 100 through the annular space through the inlet 110, the nozzle blades 410 through which the fluid passes, respectively; The turbine blade 210 may also be formed in a position and size corresponding to the annular shape of the inlet 110.

This may be roughly the same as the combination of the nozzle blade 410 and turbine blade 210 shown in Figure 3, the working fluid via the nozzle assembly 400 is increased in flow velocity by the nozzle blade 410, In order to maximize the interference with the turbine blades 210, the flow is converted in the nozzle blades 410, respectively, and transmits a physical force to the turbine blades 210, and eventually the turbine 200 is operated to rotate.

As shown in FIG. 4, the working fluid passing through the turbine 200 passes through a section in which the flow path is expanded in the inner space of the housing 100, and such a configuration is a flow path expansion guide disposed later in the turbine 200. 300).

The rotor 500 is coupled to the outer circumference of the turbine 200, and rotated together depending on the rotation of the turbine 200, in one embodiment of the present invention may be implemented in a cylindrical shape of length.

In addition, the stator 600 may be fixed to the housing 100 in a cylindrical shape whose inner diameter is larger than the outer diameter of the rotor 500, and the rotor 500 and the inner circumference of the rotating part 500 are disposed to maintain a constant interval. Can be.

The first turbine 202 may be disposed following the first nozzle assembly 402, and the first turbine blade 212 provided in the first turbine 202 may have a flow rate and a first nozzle blade 412 through the first nozzle blade 412. The first turbine 202 may be rotated in one direction by physical interference by the working fluid having the changed direction of flow.

The second nozzle assembly 404 may be provided again after the first turbine 202, and the second nozzle assembly 404 is also restrained and fixed to the housing 100.

The working fluid flowing in the case of the first turbine blade 212 is introduced into the second nozzle blade 414 of the second nozzle assembly 404, and the working fluid passing through the second nozzle blade 414 again has its flow rate and flow. Direction is changed to flow to the second turbine 204 disposed after the second nozzle assembly 404.

The second turbine blade 214 provided in the second turbine 204 may interfere with the working fluid in which the flow velocity and the flow direction are changed through the second nozzle blade 414, such that the second turbine 204 may be rotated. .

At this time, the first turbine 202 and the second turbine 204 are provided so that the direction of rotation due to the interference with the working fluid coincide with each other.

In addition, the interval through which the working fluid of the first nozzle blade 412 can pass is formed wider than the interval through which the working fluid of the second nozzle blade 414 passes, and eventually the first nozzle blade 412 is formed. The flow rate of the working fluid which is changed through the second nozzle blade 414 may be set slower than the flow rate of the working fluid which is changed through the second nozzle blade (414).

This is to allow the first turbine 202 and the second turbine 204 coupled to the inner circumference of the same rotor 500 to be rotated under the same torque. Due to this configuration, the rotor 500 is It is possible to obtain an effect that can be rotated stably.

The turbine 200 and the rotor 500 that are rotated in the inner flow path of the housing 100 may be coupled to the housing 100 by a plurality of bearings. A plurality of bearings disposed along the circumference are coupled to the rotor 500, or at least a portion of the first turbine 202 penetrates across the center of the first nozzle assembly 402 so that its ends are rotatable with the housing. It may be coupled to a bearing, at least a portion of the second nozzle assembly 404 can pass through the center of the second turbine 204, and the end of the second nozzle assembly 404 that has passed through the housing ( 100).

In this case, the second turbine 204 may also be rotatably coupled to the plurality of bearings disposed at regular intervals along the inner circumference of the housing 100.

The inlet 110 may be radially formed at one side of the housing 100 to allow the working fluid to flow toward the flow path of the housing 100, and specifically, the inlet 110 may operate as the flow path of the housing 100. The fluid may be provided in a shape that can flow in an annular shape.

Since the nozzle blades 412 and 414 and the turbine blades 212 and 214 are disposed in an annular shape, the working fluid is radially developed to form an annular shape and flows into the flow path, thereby minimizing resistance to the flow of the working fluid. .

In addition, the outlet 120 may be formed to have a diameter larger than that of the flow path in a portion adjacent to the housing 100, and may be formed such that the diameter thereof decreases away from the housing 100.

This is because when the working fluid discharged from the flow path of the housing 100 is discharged to the outlet 120 having a smaller diameter than the flow path, the flow of the working fluid may not be smooth, so that the working fluid has a minimum resistance. It is to be able to escape 100).
