Description

  The present invention relates to a wind power generator such as a fan or a circulator, and more specifically, the rotation of a rotating shaft is selectively rotated in either the forward or reverse direction, and the torsional direction of the rotating blades is directed forward or backward. The present invention relates to a wind power generation device that can change the wind feed direction from front to back or back to front by changing the above.

  For example, in a wind power generation device such as a fan or a circulator, there is a demand to change the direction in which air is pushed from front to back or back to front.

  In response to such a request, it is possible to change the wind feed direction by changing the rotation direction of the rotating shaft, but even in that case, if the angle of twist of the rotary blade is not adjusted, There will be a difference in wind power between the winds of the wind and the winds facing backwards.

  Therefore, when changing the direction in which the air is pushed forward or backward, the twisting angle of the rotating blades is changed together with the change of the rotating direction of the rotating shaft, and the changed posture of the rotating blades moves from that position. The rotating blades must be fixed in the proper position so that they do not.

  Here, for example, in a ship such as a yacht in which the water feeding direction can be changed to the front or the rear, as shown in FIG. A shaft 3 is inserted into the side surface of the nut 1 that rotates integrally with the blade, and the twist angle of the rotating blade is fixed by the shaft 3.

  However, when the shaft 3 is inserted into the side surface of the nut 1 and the twist angle of the rotary blade is fixed as described above, the shaft 3 needs to be attached and detached each time, so this mechanism is used for a fan or a circulator. When applied to a wind power generator, a complicated structure for automatically operating the shaft 3 has to be newly provided, resulting in a problem of high costs.

  In view of such a situation, the present invention is a wind power generator that enables the direction in which air is pushed to be changed, and automatically adjusts the set twist angle of the movable blade without newly providing a complicated structure. It aims at providing the wind power generator which can be fixed to.

In order to achieve the above object, a wind power generation apparatus according to the present invention comprises:
A pair of axially separable hub members;
A plurality of rotating blades housed inside the pair of hub members and radially arranged via a plurality of support shafts partially protruding from the outer peripheral surfaces of the pair of hub members are simultaneously given a predetermined angle, A synchronous gear transmission mechanism capable of rotating in the direction of rotation of the support shaft;
A rotating shaft that transmits force to the synchronous gear transmission mechanism,
The force from the rotating shaft is transmitted to the synchronous gear transmission mechanism, whereby the plurality of rotating blades are simultaneously rotated by a predetermined angle via the supporting shaft, thereby being supported by the supporting shaft. A wind power generator in which the rotating blade is selectively changed in one direction or the other direction,
Posture fixing means is provided for automatically fixing the twisting angles of the plurality of rotating blades after the plurality of rotating blades are selectively changed to one direction or the other direction. It is said.

  With such a configuration, after changing the twist angle of the rotary blade, the twist angle is automatically fixed by the posture fixing means, so that no other complicated fixing means are required, which contributes to cost reduction. Can do.

  According to the wind power generation device according to the present invention, since the posture fixing means for automatically fixing the twist angle of the rotary blade is provided, there is no influence on the wind force even when the direction of pushing air is changed. It is possible to generate a predetermined wind force.

It is. FIG. 3 is an assembled perspective view of the pair of hub members shown in FIGS. 2A and 2B.
In the following description, the surface that is visible on the near side in the visual field of FIG. 2A is the front side of each member, and the surface that is visible on the near side in the visual field of FIG. 2B is the back side of each member.

  As shown in FIGS. 1 to 3, the wind power generation device 2 according to the present embodiment includes a cylindrical first hub member 4 that can be separated in the axial direction and a second hub that fits the first hub member 4. A synchronous gear transmission mechanism A that can simultaneously rotate a plurality of rotary blades 22 arranged radially via a support shaft 13 is configured. ing.

  As shown in FIG. 2A, the synchronous gear transmission mechanism A is composed of a disk-shaped worm gear 14 and three bevel gears 13a disposed opposite to the worm gear 14, and the three bevel gears 13a are The first hub member 4 is housed in three recesses. The bevel gear 13 a is integrally formed on the base side of the support shaft 13.

  Furthermore, in the present embodiment, as shown in FIG. 4, ribs 13 c are projected from the peripheral surface of the support shaft 13. The rib 13c abuts on a groove 6d of the second hub member 6 described later during the rotating operation, so that the support shaft 13 does not rotate any more.

  The first hub member 4 and the second hub member 6 constitute a cylindrical body when they are abutted against each other as shown in FIG.

  That is, the first hub member 4 is provided with three bosses 4b on the end face of the outer peripheral side wall. Holes 4c are formed in these bosses 4b. In addition, semicircular cutouts 4 d are formed at predetermined intervals on the outer peripheral side wall of the first hub member 4.

  On the other hand, the second hub member 6 is formed with recesses 6a on the inner side of the outer peripheral side wall, and three boss holes 6b are formed at predetermined intervals on the end face of the outer peripheral side wall. These boss holes 6 b correspond to the bosses 4 b of the first hub member 4. A semicircular cutout 6c is formed on the outer peripheral side wall of the second hub member 6 so as to sandwich the boss hole 6b. These semicircular notches 6 c are formed at positions that coincide with the notches 4 d of the first hub member 4. And between the notch part 4d of the 1st hub member 4 and the notch part 6c of the 2nd hub member 6, it hold | maintains rotatably in the state which the front end side of the above-mentioned support shaft 13 protruded.

  Then, when the first hub member 4 and the second hub member 6 are assembled, the boss 4b of the first hub member 4 is inserted into the boss hole 6b of the second hub member 6 and is brought into contact with each other. After that, when the screw member 18 is inserted into the boss hole 6b from the outside of the second hub member 6 and the tip of the screw member 18 is inserted into the hole 4c of the boss 4b, as shown in FIG. The hub member 4 and the second hub member 6 can be combined and integrated with each other.

  The wind power generation apparatus 2 having such a configuration is configured to be able to arbitrarily change the case where the air feeding direction is from the rear to the front and the case from the front to the rear.

  Therefore, in this embodiment, the orientation of the rotating blade 22 in FIG. 1 can be changed in two ways so that the direction of twisting of the rotating blade 22 can be either positive or negative with respect to the rotating direction of the rotating blade 22. It is configured.

  Moreover, in such a wind power generator 2, when the attitude | position of the rotary blade 22 is set to either positive or negative, and the air feed direction is defined, it is necessary to always make the wind force the same. Therefore, in this embodiment, a posture fixing means for automatically fixing the twist angle of the rotary blade 22 is provided. This posture fixing means may be a mechanical structure or an electric structure.

  In addition to the power switch for turning the rotary shaft 30 ON and OFF, the controller of the wind power generation device 2 is provided with a switch for switching the air feed direction from the rear to the front or from the front to the rear. Yes. That is, in this embodiment, the operator can select the direction of the wind flow via the controller of the wind power generation device 2. In this embodiment, the rotation axis 30 is simultaneously rotated by determining the air (wind) feed direction.

Hereinafter, the operation of the wind power generator 2 configured as described above will be described.
Now, in the wind power generation device 2, a case will be described in which air is sent to a person in front with the air flow from the rear to the front as in a normal electric fan.
First, the operator confirms the direction in which the wind flows from the controller, turns on the rotation shaft 30 with the forward / reverse switching switch, and rotates the rotation shaft 30 in the forward direction (in the direction of arrow X in FIG. 2A).

  When the drive of the rotary shaft 30 is turned ON in the forward rotation direction, the support shaft 13 receives the force of the synchronous transmission mechanism A, and these rotate in the arrow X direction in FIG. 2A. Due to the rotation of the support shaft 13 in the X direction, wind force is generated forward (in the direction from the second hub member 6 toward the first hub member 4). When such wind power is generated, the force acts on the rotary blade 22 and a predetermined air volume is supplied from the rear to the front. Further, during forward rotation, the rib 13c of the support shaft 13 abuts against the edge of the recess of the first hub member 4, so that the twist angle of the rotary blade 22 is fixed and does not move.

On the other hand, a case will be described in which the flow direction of the wind is changed from the front to the rear (the direction from the first hub member 4 toward the second hub member 6). From the state in which the rotation of the rotary shaft 30 is stopped, the operator selects the direction in which the wind flows from the forward / reverse switching switch of the controller. That is, the air is selected to flow from front to back.
In this way, when the air flow is selected from the front to the rear, the rotary blade 22 is in a movable state because the twisted posture is not stable.

  However, when the support shaft 13 rotates in the Y direction, wind force in a direction from the first hub member 4 toward the second hub member 6 is generated. When such wind force is generated, the force acts on the rotary blade 22. Then, in this embodiment, the wind force at that time acts on the rib 13c of the support shaft 13 as posture fixing means for automatically fixing the twist angle of the rotary blade 22. Then, the support shaft 13 is rotated by receiving the wind force acting on the rotary blade 22, the rib 13 c collides with the groove 6 d of the second hub member 6, and thereafter, the rotary blade 22 does not rotate. Thereby, the twist angle of the rotary blade 22 is fixed at a predetermined position, and thereafter the rotary blade 22 rotates in an accurate twist posture.

  Therefore, according to the present embodiment, the position of the rotary blade 22 is automatically set to a predetermined position regardless of whether the air is sent from the front to the front or the air is sent from the front to the back. In this case, it is possible to secure an appropriate air volume.

  As described above, according to the present invention, when the wind power generation device that allows the direction of air to be changed is reversely rotated, the angle of twist of the movable blade is automatically provided without newly providing a complicated structure. It became possible to fix.

As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example at all. For example, the posture fixing means for automatically fixing the twist angle of the rotary blade 22 is not limited to a mechanical structure such as the rib 13c, but may be fixed by an electric means.
Further, the number of the rotary blades 22 is not limited to three and may be four or more.

  Further, in the above embodiment, the wind power generation device 2 has been described with ease of use like a fan. However, the wind power generation device 2 can be used for a circulator that circulates air from the top to the bottom or from the bottom to the top Applicable.
