The present invention relates to a power generation device, a generator, a power generation method, and a power generation method that generate rotational power in a non-contact manner using a swirl flow.

Conventionally, the technology shown in FIG. 11 is known as this type of power generation device (see, for example, Patent Document 1). In the power generation device 100, the extension support mechanism 101 is moved in the predetermined rotation range of the floating body 102 by the roller 106 being moved outward by the extending action portions 105 of the inner guide rail 103 and the outer guide rail 104, and the length is extended. As a result, the distance from the rotating shaft 107 of the floating body 102 becomes longer, and when the rotation body 108 exceeds a predetermined rotation range, the roller 106 is detached from the inner guide rail 103 and the outer guide rail 104, and the floating body 102 rises from the water surface. As a result, the gravity that the floating body 102 receives is larger than the buoyancy, and the length is reduced by the weight and the reduction action portion 109 of the outer guide rail 104, and the distance from the rotating shaft 107 of the floating body 102 is shortened.

According to this power generation device 100, by automatically adjusting the distance of the floating body 102 from the rotating shaft 107, the moment applied to the rotating shaft 107 is increased or decreased by the action of buoyancy and gravity, and the rotating shaft 107 is efficiently rotated. Can be made.

However, the conventional power generation device 100 has many movable parts due to contact, and friction is generated in the movable parts. Therefore, the extraction efficiency of kinetic energy is lowered, and the movable part is worn and cannot be used for a long time. there were.

Further, the conventional power generation device 100 has a problem that it cannot be easily manufactured and is expensive because it has a large number of parts and a complicated structure.

The present invention has been made in view of such circumstances, and the main object thereof is a power generation device, a generator, and a power generator that generate power efficiently with a simple structure, without aging deterioration due to friction, and Another object is to provide a power generation method and a power generation method.

According to the power generation device according to the first aspect of the present invention, the container main body, the liquid fluid introducing portion provided in the container main body for introducing the liquid fluid into the container main body, and the container main body are provided. A discharge part that discharges the liquid fluid introduced from the liquid fluid introduction part, and a liquid fluid that is provided in the container body and that is introduced from the liquid fluid introduction part spirally toward the discharge part The liquid fluid swirling portion to be moved, and a power generating portion that is movable in the axial direction of the container main body and rotated by the swirling flow by the discharge flow rate of the swirling flow generated by the liquid fluid swirling portion.

With the above configuration, when the discharge flow rate of the swirling flow (liquid fluid) from the discharge portion starts to increase, the liquid pressure around the swirling pivot generated by the liquid fluid swirling portion in the container body decreases, and the container body This is the first state in which the hydraulic pressure in the vicinity of the inner discharge portion is extremely lower than the hydraulic pressure outside the container body. In the first state, the power generation unit tends to move forward in the axial direction of the container body. However, when the discharge flow rate of the swirling flow (liquid fluid) from the discharge unit starts to decrease, the second state where the hydraulic pressure in the vicinity of the discharge unit in the container body becomes higher than the hydraulic pressure outside the container body. Due to the second state, the power generation unit tends to move rearward in the axial direction of the container body. The first state and the second state are repeatedly generated instantaneously, so that the axial force of the container body applied to the power generation unit is canceled out, and the power generation unit stays in a balanced state automatically. And rotates in conjunction with the swirl flow generated by the liquid fluid swirl. Accordingly, it is possible to provide a new power generation device that uses such an operating principle.

Further, according to the power generation device according to the second aspect of the present invention, the inner wall is annular in a longitudinal sectional view, and is configured to have a shape that decreases in diameter as it advances rearward in the axial direction from a predetermined position. it can.

With the above configuration, the inner wall is reduced in diameter as it advances rearward in the axial direction of the container body, so that the swirl flow can be gradually accelerated along the inner wall.

Furthermore, according to the power generation device according to the third aspect of the present invention, the inner wall can have an inner wall flat part in the vicinity of the discharge part.

With this configuration, the swirling flow is discharged from the discharge portion substantially perpendicularly to the axial direction of the container body on the inner wall because the flat portion is formed in the vicinity of the discharge portion of the inner wall. As a result, the flow velocity in a substantially vertical direction increases, and the turning force of the self can be increased.

Furthermore, according to the power generating device according to the fourth aspect of the present invention, the outer wall can be configured to have an outer wall flat part in a wider area around the discharge part than the inner wall flat part.

With the above configuration, since the outer wall is provided with a flat portion in a wider range, substantially perpendicular to the axial direction of the container body, the flow velocity in the direction substantially perpendicular to the axial direction of the container body increases, The turning force of can be increased.

Furthermore, according to the power generation device according to the fifth aspect of the present invention, the outer wall can have an annular protruding wall protruding in a reduced diameter direction from a predetermined position of the outer wall flat portion.

With the above configuration, the swirling flow is discharged from the discharge portion substantially perpendicular to the axial direction of the inner wall of the container body, and is also guided to the rear of the container body in the axial direction by colliding with the annular protruding wall. That is, the outer wall flat part and the annular projecting wall can have both a function of pushing a baffle plate, which will be described later, to the rear in the axial direction of the container body and a function of increasing the rotational force of the swirling flow.

According to the power generation device of the sixth aspect of the present invention, the power generation unit is provided substantially perpendicularly to the discharge unit, and is supported by the container body, inserted through the support shaft, An insertion hole having a diameter larger than the shaft diameter of the support shaft may be provided, and a baffle plate inserted through the support shaft so as to be movable in the axial direction of the container body through the insertion hole.
With the above configuration, when the swirl flow is discharged from the discharge unit, the baffle plate is pushed by the swirl flow and tries to move backward, and when the swirl flow continues, the hydraulic pressure in the vicinity of the discharge unit in the container body is increased. It becomes extremely lower than the hydraulic pressure outside the container body, and the baffle plate tries to move toward the discharge part. The swirling flow is guided rearward in the axial direction of the container body by being discharged from the discharge portion substantially perpendicular to the axial direction of the container body on the inner wall. The force pushing this baffle plate becomes balanced with the suction force due to the low hydraulic pressure inside the container body, and the baffle plate has an insertion hole larger in diameter than the shaft diameter of the support shaft. Both the axial direction of the container body and the direction substantially perpendicular to the axial direction of the container body are in a balanced state and are substantially stationary at a fixed position. As described above, the swirling flow and the baffle plate balance the force that pushes the swirling flow in the axial direction rearward of the container body and the force that the baffle plate is sucked in the direction opposite to the axial rearward of the container body (forward). Thus, the baffle plate can rotate in conjunction with the rotation of the swirl flow. In other words, the baffle plate can be rotated in a non-contact manner with the support shaft in a balanced state. As a result, power can be efficiently generated and used for a long time without being worn. It is possible to provide a power generation device that can

Furthermore, according to the power generation device according to the seventh aspect of the present invention, a hole provided substantially perpendicular to the discharge portion, provided in the container main body, inserted into the hole, and smaller in diameter than the hole diameter of the hole. And a baffle plate inserted into the hole so as to be movable in the direction of the insertion axis via the insertion axis.

With the above configuration, the same effect as that of the power generation device according to the sixth aspect of the present invention, that is, power that can be generated efficiently and can be used over a long period of time without being worn. A generator can be provided.

Furthermore, according to the power generation device of the eighth aspect of the present invention, the power generation unit is configured such that the baffle plate is positioned at the position where the low hydraulic pressure generated in the container body reaches the support shaft. Or it can have a stopper part for not separating from the hole.

Furthermore, according to the power generation device according to the ninth aspect of the present invention, the liquid fluid introduction section is annular in the longitudinal sectional view so that the liquid fluid spirally turns toward the discharge section. The liquid fluid can be introduced along the tangential direction.

With the above configuration, the liquid fluid introduction part and the liquid fluid swirl part also serve as each other, and for example, the liquid fluid can be swirled spirally without providing a screw separately, so that it becomes a simpler structure, It is economical in terms of manufacturing cost and running cost.

Furthermore, according to the power generation device according to the tenth aspect of the present invention, when the discharge flow rate of the liquid fluid from the discharge unit increases, the power generation unit generates a swirl flow generated by the liquid fluid swirl unit. When the liquid pressure around the pivot axis is lowered, the liquid pressure in the vicinity of the discharge section in the container body is lower than the liquid pressure outside the container body, and the liquid fluid from the discharge section When the discharge flow rate decreases, the liquid fluid swirl automatically adjusts so that the liquid pressure in the vicinity of the discharge part in the container body is balanced with the second state in which the liquid pressure outside the container body is higher. It can be rotated by the swirl flow generated by the section.

According to the above configuration, when the discharge flow rate of the swirl flow (liquid fluid) from the discharge unit starts to increase, the liquid pressure around the swirl swivel axis generated by the liquid fluid swirl unit is reduced in the container body, This is the first state in which the hydraulic pressure in the vicinity of the discharge portion in the container body is extremely lower than the hydraulic pressure outside the container body. In the first state, the power generation unit tends to move forward in the axial direction of the container body. However, when the discharge flow rate of the swirling flow (liquid fluid) from the discharge unit starts to decrease, the second state where the hydraulic pressure in the vicinity of the discharge unit in the container body becomes higher than the hydraulic pressure outside the container body. Due to the second state, the power generation unit tends to move rearward in the axial direction of the container body. The first state and the second state are repeatedly generated instantaneously, so that the axial force of the container body applied to the power generation unit is canceled out, and the power generation unit stays in a balanced state automatically. And rotates in conjunction with the swirl flow generated by the liquid fluid swirl. Accordingly, it is possible to provide a new power generation device that uses such an operating principle.

It can be accelerated.

Moreover, the outer shape of the container body 2 is formed in a shape that follows, for example, a cylindrical shape or an inner wall shape. In the case of a cylindrical shape, since it is formed in a simple cylindrical shape regardless of the shape of the inner wall, it can be easily manufactured. Moreover, in the case of the shape along the shape of the inner wall, the outer shape is fitted to the shape of the inner wall, so that the container body 2 is not given an extra thickness, and the material cost can be suppressed.

As shown in FIG. 2, the inner wall flat portion 21 is a flat portion of the inner wall of the container main body 2 that is substantially perpendicular to the diameter reducing direction and is provided in the vicinity of the discharge portion 4.

As shown in FIG. 2, the outer wall flat portion 22 is a flat portion of the outer wall of the container body 2 that is substantially perpendicular to the diameter reducing direction, and is provided around the discharge portion 4 in a wider range than the inner wall flat portion 21. ing.

As shown in FIG. 2, the annular projecting wall 23 is provided so as to project in a reduced diameter direction from a predetermined position of the outer wall flat portion 22.

As shown in FIG. 3, the swirling flow is discharged from the discharge portion 4 by the inner wall flat portion 21 formed in the vicinity of the discharge portion 4 on the inner wall substantially perpendicularly to the axial direction of the container body 2 on the inner wall, and the outer wall Further, the outer wall flat portion 22 provided in a wider range substantially perpendicularly to the axial direction of the container main body 2 increases the propulsive force in the substantially vertical direction with respect to the axial direction of the container main body 2 and rotates itself. The power can be increased. Further, the swirling flow is discharged from the discharge portion 4 substantially perpendicularly to the axial direction of the container body 2 on the inner wall, and collides with the annular projecting wall 23 to cause the container body 2 to move rearward in the axial direction (right direction in FIG. 3). ). That is, the outer wall flat portion 22 and the annular projecting wall 23 have both a function of pushing a baffle plate 62 to be described later in the axial direction rearward of the container body 2 and a function of increasing the rotational force of the swirling flow. Becomes balanced with the suction force by the low hydraulic pressure in the container body 2.

The liquid fluid introducing unit 3 is, for example, a pipe, provided at an upstream end of the container body 2, and a flow path for introducing the liquid fluid L2 pumped by the pumping means PR into the container body 2, and Serves as an introduction port. The liquid fluid L2 introduced from the liquid fluid introduction part 3 flows toward the discharge part 4 located downstream. As shown in FIGS. 4A and 4B, the liquid introduction unit 3 is configured so that the liquid fluid L2 is spirally turned toward the discharge unit 4 along the tangential direction of an annular shape in cross section. It is good also as a structure provided in a part of surrounding surface of the container main body 2 so that may be introduced. As a result, the liquid fluid introduction unit 3 also serves as the liquid fluid swirl unit 5 and, for example, the liquid fluid L2 can be swirled helically without the need for a separate screw 51. It is economical in terms of manufacturing cost and running cost.

The discharge part 4 is provided at the downstream end of the container body 2 and is introduced from the liquid fluid introduction part 3 and discharges the spirally swirling liquid fluid L2 to the outside of the container body 2.

As shown in FIG. 2, the liquid fluid swirling unit 5 is, for example, a screw 51 provided with a plurality of blades, and is rotatably provided on the liquid fluid introducing unit 3 side in the container body 2. The screw 51 is rotated by the liquid fluid L2 sent by the pressure feeding means PR, and the screw 51 is rotated, so that the liquid fluid L2 becomes a swirling flow. In this way, the liquid fluid swirling unit 5 sends out the liquid fluid L2 introduced from the liquid fluid introducing unit 3 toward the discharge unit 4 while spirally swirling.

As shown in FIG. 5, the power generation unit 6 includes a support shaft 61, a baffle plate 62 having an insertion hole 621 inserted through the support shaft 61, and a baffle plate 62 so as not to be detached from the support shaft 61. The stopper part 611 provided is provided as a main part.

The support shaft 61 is, for example, a tube, and is provided substantially perpendicular to the discharge unit 4 and supported by, for example, a stainless plate 612 so that the baffle plate 62 can be inserted and supported as shown in FIG. 5A. The stainless steel plate 612 is connected to the container body 2 via bolts 613. The stainless steel plate 612 and the bolt 613 are not limited to the materials and shapes as long as they can support the support shaft 61.

As shown in FIG. 5B, the baffle plate 62 is, for example, a disc made of stainless steel having an insertion hole 621 in the approximate center, and is in the axial direction of the support shaft 61 as shown in FIG. And the stopper portion 611 through the insertion hole 621 so as to be movable, and rotate in conjunction with the swirl flow. The baffle plate 62 only needs to be able to rotate in conjunction with the swirling flow, and is not limited to the material or shape. Moreover, the liquid L1 in the tank TA containing the liquid fluid L2 discharged from the discharge part 4 can be stirred by providing the baffle plate 62 with a stirring blade. In this case, the power generation device 1 can also be used as a stirrer.

As shown in FIG. 5, the insertion hole 621 is larger in diameter than the shaft diameter of the support shaft 61, and the baffle plate 62 is movable through the insertion hole 621 in the axial direction of the support shaft 61. Is inserted.

Therefore, the outer wall flat portion 22 and the annular projecting wall 23 have both a function of pushing the baffle plate 62 in the axial direction rearward of the container body 2 and a function of increasing the rotational force of the swirling flow. The suction force due to the low hydraulic pressure in the container body 2 is balanced, and the insertion hole 621 is larger than the shaft diameter of the support shaft 61, so that the shaft of the container body 2 does not contact the support shaft 61. Both the direction and the direction substantially perpendicular to the axial direction of the container body 2 are in a balanced state and are substantially stationary at a fixed position. Therefore, power can be generated without contacting the support shaft 61.

In the stopper portion 611, for example, the shaft 61 is stepped, and the movement of the baffle plate 62 is restricted at the stepped position of the shaft 61, thereby serving as a stopper.

In the example shown in FIG. 5, the power generation unit 6 includes a support shaft 61, a baffle plate 62 having an insertion hole 621 inserted through the support shaft 61, and the baffle plate 62 from the support shaft 61. Although the case where it has as a main part the stopper part 611 provided in this way was demonstrated, this invention is not limited to this.

The power generation unit 6 may be in any form as long as it is configured to be movable in the axial direction of the container body 2. For example, as shown in FIG. 6, the power generation unit 6 has an insertion shaft 61 ′. A baffle plate 62 ′, a stainless steel plate 612 ′ having a hole 614 ′ to be inserted into the insertion shaft 61 ′, and a stopper portion 611 ′ provided so that the insertion shaft 61 ′ of the baffle plate 62 ′ is not detached from the hole 614 ′. It is good also as a structure which has as a main part.

The stainless steel plate 612 'is connected to the container body 2 via a bolt 613', as in the example shown in FIG.

As shown in FIG. 6, the baffle plate 62 ′ is, for example, a disc with a shaft made of stainless steel having an insertion shaft 61 ′ at a substantially center, and is in the axial direction of the container body 2 (insertion shaft 61 ′). It is inserted between the discharge part 4 and the stopper part 611 'via the hole 614' so as to be movable in the axial direction of the container body 2, and rotates in conjunction with the swirling flow.

As shown in FIG. 6, the hole 614 ′ is larger in diameter than the insertion shaft 61 ′, and the insertion shaft 61 ′ of the baffle plate 62 ′ passes through the hole 614 ′ in the axial direction of the container body 2. And is inserted into the hole 614 '.

Therefore, the outer wall flat portion 22 and the annular projecting wall 23 have both a function of pushing the baffle plate 62 ′ rearward in the axial direction of the container body 2 and a function of increasing the rotational force of the swirling flow. The force pushing the shaft 2 rearward is balanced with the suction force due to the low hydraulic pressure in the container body 2, and the hole 614 ′ is larger in diameter than the shaft diameter of the insertion shaft 61 ′. Without being in contact with each other, both the axial direction of the container main body 2 and the direction substantially perpendicular to the axial direction of the container main body 2 are balanced and become substantially stationary at a fixed position. Therefore, the insertion shaft 61 ′ of the baffle plate 62 ′ can generate power without coming into contact with the hole 614 ′.
(Operation of power generation device 1 and power generation method)

Next, the operation and power generation method of the power generation device 1 of the present invention will be described with reference to the longitudinal cross-sectional view of the container body 2 in FIG. 2 and the flowchart in FIG. 7A. The power generation device 1 operates by repeating the following steps ST1 to ST5 continuously.

In step ST1 (corresponding to the liquid fluid introduction step of claim 12), the pressure feeding means PR introduces the external liquid fluid L2 into the container body 2 via the liquid fluid introduction part 3.

In step ST2 (corresponding to the liquid-fluid swirl process of claim 12), the screw 51 spirals along the inner wall of the container body 2 with the liquid fluid L2 pumped in step ST1 directed toward the discharge portion 4. It generates a powerful flow that swirls.

In step ST3, since the inner wall of the container body 2 is reduced in diameter toward the discharge unit 4, the swirl flow generated in step ST2 is gradually accelerated along the inner wall.

In step ST4, the swirling flow accelerated in step ST3 is discharged out of the container body 2 from the discharge unit 4.

In step ST5 (corresponding to the power generation step of claim 12), the baffle plate 62 generates rotational power in conjunction with the swirling flow discharged in step ST4.
(Operation of the power generation unit 6)

Here, the operation of step ST5 will be described in detail below with reference to the flowcharts of FIGS. 8 and 9 for explaining the relationship between the baffle plate 62 and the force acting on the baffle plate 62.

In step ST51, when the swirling flow is discharged from the discharge unit 4, the baffle plate 62 is pushed by the swirling flow and attempts to move rearward in the axial direction of the container main body 2, whereby the container main body 2 of the power generating unit 6 is moved. The axial position is adjusted.

In step ST52, when the discharge of the swirl flow continues, the hydraulic pressure in the vicinity of the discharge section 4 in the container main body 2 is in a first state in which it is extremely lower than the hydraulic pressure outside the container main body 2, and the baffle plate 62 is moved by the suction force SF. The position of the power generating unit 6 in the axial direction of the container main body 2 is adjusted by moving toward the discharge unit 4 in the axial direction of the container main body 2.

In step ST53, when the discharge flow rate of the liquid fluid L2 from the discharge part 4 decreases, the liquid pressure in the vicinity of the discharge part 4 in the container main body 2 becomes the second state in which the liquid pressure outside the container main body 2 becomes higher, and the swirl flow The axial position of the container main body 2 of the power generator 6 is adjusted by trying to move the container main body 2 rearward in the axial direction by the pressing force PF.

In step ST54, the first state of step ST52 and the second state of step ST53 are instantaneously repeated, so that the force applied to the baffle plate 62 in the axial direction of the container body 2 is canceled, and the baffle plate 62 is Since the insertion hole 621 is larger in diameter than the shaft diameter of the support shaft 61, the insertion hole 621 is not in contact with the support shaft 61 and also in a direction substantially perpendicular to the axial direction of the container body 2. In contrast, in a state of being automatically balanced, rotational power can be generated in a fixed position in a non-contact manner with the support shaft 61 in conjunction with the swirling flow. Note that steps ST51 to ST54 operate repeatedly and continuously.
(Generator 7)

As shown in FIGS. 10 and 11, the generator 7 includes a power generation device 1 (broken line portion in FIG. 10) and a power conversion unit 71 as main parts.

As shown in FIGS. 11A and 11B, the power conversion unit 71 includes, for example, a coil 711 and a permanent magnet 712, and the coil 711 is provided in non-contact with the baffle plate 62, and the permanent magnet 712 includes the baffle plate. 62. When the baffle plate 62 rotates, an induction current is generated in the coil 711 by electromagnetic induction. That is, the power conversion unit 71 converts the rotational power of the baffle plate 62 into electric power.
