Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sign wind power generator using wind power generated when a vehicle such as a train or an automobile passes.
[0002]
[Prior art]
Various generators using natural energy such as hydropower and wind power have been proposed. For example, Japanese Laid-Open Patent Publication No. 58-130742 discloses a portable water turbine generator, which is installed in a mountain stream as appropriate in order to obtain electricity for outdoor lighting to enjoy camping, fishing, etc. It is done. An example of a generator using hydraulic power is described in Japanese Utility Model Publication No. 63-171675. The generator described in this publication is provided with a rotor having a magnet inside a water supply pipe, and rotates the rotor by passage of a water flow. And the electric power obtained from this generator can be utilized in various places. On the other hand, an example of a generator using wind power is disclosed in Japanese Patent Laid-Open No. 52-129855. The rotor blades of this generator are of the propeller type, and the generator body is provided with a tail blade, and the rotating shaft freely rotates in accordance with the wind direction. Therefore, the installation location of this generator is not particularly limited.

As described above, various generators using natural energy have been proposed in the past. However, these generators are installed in a "specific place", "how to install" No specific proposal was made regarding "use". Therefore, various proposals (invention / utility model) were not put into practice and were disliked.

Now, the rectangular frame-shaped housing | casing 20 is preferably formed in consideration of the radius of the guard support | pillars 3a and 3a. That is, the depth is set shallow so as not to protrude significantly from the guard column 3a. A plurality of handles 23 are appropriately attached to the left and right side walls 20a, 20b of the housing 20. Further, the upper wall 20c of the housing 20 is formed with a plurality of protrusions 24 that engage with the vertical wall 14a after passing through the fitting notches 17 of the upper support rod 14 described above. Therefore, the fitting of the rectangular frame-shaped housing 20 and the support member 10 corresponds to the fitting relationship between the shoji and the shoji frame.

The configuration of the small generator body 22 will be described with reference to schematic FIGS. 7 to 9. Reference numeral 25 denotes a support frame of the small generator body 22. The support frame 25 is a cassette type, and fits perfectly in a state where the large and small generator bodies 21 and 22 are combined in the casing 20 described above. Reference numeral 26 denotes a rotating shaft that is rotatably supported by a long cylindrical bearing portion 27 provided at the center of the support frame 25, and blades 28 are radially fixed to the rotating shaft 26. As shown in FIGS. 7 and 9, the blade 28 is a fan type having a magnet mounting portion. Preferably, a curved winded portion 28 b is formed at the location of the blade 28. Further, the first permanent magnet 29 of the curved plate is sequentially fixed to the outer wall surface at the tip of the blade 28 in the circumferential direction, such as “S pole” and “N pole”. Further, as shown in FIG. 9, the second permanent magnet 30 is sequentially fixed to the shaft portion 28 a of the blade 28 in an annular manner, such as “S pole” and “N pole”. The rotor includes a rotating shaft 26, a blade 28 formed integrally with the rotating shaft 26, and first and second permanent magnets 29 and 30 fixed to the blade 28 in an annular shape.

On the other hand, in the box-shaped support frame 25 corresponding to the stator, a large number of protruding conductor mounting portions 31 are provided in an annular shape so as to face the first and second permanent magnets 29, 30. A power generation coil 32 is wound around each of the conductor attachment portions 31 in a bobbin shape. In this embodiment, the box-shaped support frame 25 and the protruding conductor mounting portion are formed of a non-magnetic material (for example, a hard synthetic resin material).
[0018]
Next, reference numeral 35 denotes a plurality of wind guide plates provided on the small generator main body 22. In the present embodiment, these wind guide plates 35 are fixedly provided on the opening edge 25a so as to protrude forward from the front opening edge of the support frame 25 with a required angle.
[0019]
The case where the cassette type generator 11 is set on the support member 10 in the above configuration will be described. First, before setting the cassette type generator 11 on the support member 10, the large and small generator bodies 21 and 22 are assembled in the rectangular frame-shaped casing 20 as shown in FIG. 6.

Next, the cassette type generator 11 having a plurality of generator bodies is set on the support member 10. In this case, the generator 11 is once lifted by holding the handle 23 of the set-type generator 11, and the hand is released from the handle 23 so that the bottom of the generator 11 is aligned with the inner surface of the bottom wall 15 b of the lower support rod 15. Therefore, if the bottom of the generator 11 is engaged with the lower support rod 15, each generator 11 is pushed down appropriately against the spring force of the left and right elastic members 18, 18. The protrusion 24 is aligned with each fitting notch 17 of the upper support rod 14. Then, when both hands are released from the generator 11 at the place where each projection 24 is passed through each fitting notch 17, the generator 11 is slightly lifted by the spring force of the left and right elastic members 18, 18. Each projection 24 engages with the vertical wall 14a of the upper support rod 14. Then, the generator 11 is supported by the support member 10 in a manner supported by the left and right elastic members 18, 18.
[0021]
In this way, the plurality of cassette type generators 11 are arranged along the highway 1 through the support member 10 in the lower space 12 of the guardrail body 3b of the vehicle workpiece 3 as shown in FIGS. It is arrange | positioned in a horizontal line and becomes the wind power generator 4 for signs.
[0022]
【Example】
In the embodiment of the present invention, the case where the wind power generator 4 for signage is installed on the vehicle workpiece 3 provided in the median strip of the highway has been described, but the present invention is not limited to this. For example, you may attach the wind power generator 4 to the vehicle workpiece with respect to vehicles, such as a Shinkansen and a subway. In short, it may be installed on a vehicle workpiece in a place where a desired wind is frequently generated by a traveling vehicle. When the vehicle workpiece 3 is a guard rail, the wind power generator 4 is disposed in the lateral direction via the support member 10 in the lower space 12 of the guard rail main body 3b. It is not necessary to arrange in the space part 12. For example, you may arrange | position in the upper space part of the guardrail main body 3b of the workpiece 3 for vehicles. In this case, it is necessary to project a required amount of the upper end side of the left and right girth columns 3a, 3a from the guardrail body 3b. Furthermore, in the present embodiment, the blades 28 of the generator main body 21 (22) are fan-shaped, but are not necessarily limited thereto. Since it is desirable for the wing 28 to rotate even in a weak wind, it may be a crossflow type wind turbine recently invented by Mr. Tsuji, who specializes in fluid engineering. The generator 11 includes a rectangular frame-shaped housing 20 and a plurality of generator bodies having a box-shaped support frame 25 incorporated in the housing 20. May incorporate only one generator body. In addition, another power generation means (for example, a solar power generator) may be attached to the upper support rod 14 of the support member 10 and both may be combined to increase the power generation.
[0023]
【The invention's effect】
As is clear from the above description, the present invention has the following effects.

(2) Since a plurality of generators are attached to a vehicle workpiece, existing struts and spaces can be used.
(3) Since only a heavy generator is lifted and fitted into a support member having a locking function, the attaching operation to the support member is easy.
(4) Since the cassette generator is provided with a plurality of generator bodies, a large amount of power generation can be obtained.
(5) In the embodiment (4), in the embodiment in which the cassette type generator is composed of a rectangular casing and a generator main body having a plurality of box-shaped support frames 25, a plurality of cassette generators are included in the rectangular casing.
