Description

The present invention relates to a wind power generation device mounted on an upright wall such as a snow fence or a wind fence installed on a road to shield, for example, a blizzard or a strong wind.

In snowy countries and cold regions, blizzards are sprayed on trunk roads with wide plains during winter, and if the roads are covered with snow, the passage of vehicles will be hindered. In addition, when a blizzard blows on the road, the driver's field of vision is obstructed and the driving of the vehicle is obstructed. Snow fences are installed on one or both sides of the trunk road to prevent snow damage caused by such a blizzard. In addition, by generating electricity using the wind of a blizzard that crawls on the ground, it is used as a power source for road lighting and delineators, and as a power source for preventing freezing of the road surface. There is.

For example, the blow-off fence described in Patent Document 1 is installed on one side of a road where a blizzard blows, a non-perforated plate is installed in series at the lower part, and a stealth and a guide plate are installed at the upper part. A perforated plate consisting of parts is bent and installed in a side view. Then, by replacing the perforated plate provided at the upper part of the blow-off fence with a snow-proof plate unit, it is used for wind power generation. In the snow plate unit, blades are rotatably installed around a rotation axis in a rectangular frame, and a generator that generates electricity based on the rotation of the blades is provided in the frame. Furthermore, the blade that rotates with wind power has a wind reduction effect.

Japanese Unexamined Patent Publication No. 2016-205106

However, the wind power generation device using the blizzard described in Reference 1 has a problem that the size of the blade is limited by the rectangular frame and the power generation efficiency is poor because the small blade functions as a wind turbine. Moreover, since the snowstorm passes through the gap between the frame and the rotatable blade, snow accumulates on a part of the road surface, and it is necessary to remove the snow.
In addition, it is necessary to incorporate the snow plate unit into the design at the stage of installing the blow fence, and if the existing perforated plate of the blow fence is replaced with the snow plate unit and installed, the construction cost will increase and the cost will increase. There is also.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a wind power generation device that can be easily installed on an upright wall and can be installed at a low cost.

The wind power generator according to the present invention includes a snow-proof or wind-proof upright wall, a windmill mounting member that is provided with a windmill and can be mounted on the upper part of the upright wall, and a generator that generates electricity based on the rotation of the windmill. It is characterized by that.
According to the present invention, when a blizzard or a strong wind rises from the ground surface along an upright wall, a windmill provided on a windmill mounting member installed outside the upright wall can be rotated to generate electricity with a generator. it can. The electric power generated by the generator can be used as a power source for various lighting fixtures and heating fixtures.

Further, it is preferable that the wind turbine mounting member includes a locking recess that can be mounted on the upright wall, and a wind turbine provided on the surface of the locking recess on the side where the ground blizzard or strong wind blows.
By mounting the locking recess of the wind turbine mounting member on the upright wall, the wind turbine can be installed on the surface on the side where the ground blizzard or strong wind blows. Can be installed separately.

Further, the wind turbine provided in the wind turbine mounting member may have at least a part protruding above the upper end of the upright wall.
The wind turbine can be used for power generation by receiving a crosswind that blows above the upright wall separately from the blizzard and strong wind that rises along the upright wall.

In the wind power generation device according to the present invention, since the wind turbine mounting member can be installed on the upper part of the existing or new standing wall, the wind turbine mounting member can be easily mounted at low cost, and a snowstorm or the like invades through the gap between the standing wall and the wind turbine. You can prevent that.

It is a side view of the wind power generation device provided with the snow fence according to the embodiment of this invention. It is a front view of the wind power generation device provided in the snow fence shown in FIG. It is an enlarged view of the wind power generation device shown in FIG. It is a side view of the wind power generation device by the modification.

Hereinafter, the wind power generation device 1 according to the embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows, for example, on a main road 2 (hereinafter, simply referred to as a road 2) provided in a snowy area or a cold area, a snow fence 3 for preventing a snowstorm is provided at one widthwise end 2a of the road 2 where the wind blows. is set up. The snow fence 3 can be used not only for snow protection but also for wind protection. The snow fence 3 may be installed at both end portions 2a instead of one width direction end portion 2a of the road 2. A strong wind blows against the snow fence 3 from the opposite side of the road 2, and when it snows, a blizzard blows.
Ground blizzard is a phenomenon in which the snow that has fallen on the ground is blown up by a strong wind and flies in a turbulent manner. Specifically, as shown by an arrow in FIG. 1, snow that is blown horizontally along the ground surface by a strong wind collides with the snow fence 3 and rises along the snow fence 3 to blow up.

In the snow fence 3 shown in FIGS. 1 and 2, columns 5 are erected at predetermined intervals along one widthwise end 2a of the road 2, and for example, a metal snow plate 6 is installed between the columns 5. Has been done. The support column 5 is installed by, for example, H-shaped steel, and a concrete foundation block 7 is connected to the lower end portion of the support column 5. The foundation block 7 is buried underground. Further, a girder member 8 made of a pipe, a bar member, a plate member, or the like connecting the columns 5 is connected to the upper end portion of the snowproof plate 6.

As shown in FIG. 3, a wind turbine mounting member 9 having a substantially U-shaped cross section is fitted to the upper end of the snow plate 6. The wind turbine mounting member 9 is formed by the back surface 9a, the front surface 9b, and the top plate 9c as a locking recess having a substantially U-shaped cross section, and can be mounted on the upper end of the snow fence 3. A wind turbine support frame 10 having a substantially triangular cross-sectional view is installed on the surface 9b of the wind turbine mounting member 9, and a rotating shaft 12 of the wind turbine 11 is fitted at the top of the substantially triangular cross-sectional view.
The wind turbine support frame 10 is formed in the shape of an isosceles triangle or an isosceles right triangle with the surface 9b of the wind turbine mounting member 9 as the base and the support legs 10a and 10b extending from the surface 9b set to the same length. For example, four blades 13 are arranged at equal intervals on the rotating shaft 12 of the wind turbine 11. Each blade 13 is formed in a cross-sectional view so as to easily receive a snowstorm, and a slight gap s is formed between the rotation locus of the blade 13 and the surface 9b of the wind turbine mounting member 9.

As shown in FIG. 3, the wind turbine 11 is installed at the upper end of the snow fence 3 and does not project above the snow fence 3. The wind turbine 11 receives the blizzard rising along the snow fence 3 with the blades 13 having a cross-sectional view, and is made capable of rotating counterclockwise in FIG. The wind turbine mounting member 9 has a screw portion 15 screwed into a screw hole 9d formed at the lower end portion of the back surface 9a, and a push plate 16 is provided at the tip thereof. By tightening the screw portion 15 with the wind turbine mounting member 9 fitted to the snow fence 3, the push plate 16 provided at the tip of the screw portion 15 can be pressed and fixed to the snow fence 3.

A generator support member 18 having a substantially U-shaped cross section is fitted to the upper end portion of the snow fence 3 at a position adjacent to the wind turbine 11, and the push plate 16 is tightened by the screw portion 15 in the same manner as the wind turbine mounting member 9. As a result, the push plate 16 can be pressed and fixed to the snow fence 3 (not shown). The generator 20 is fixed to the generator support member 18, and the generator 20 is connected to one end of the rotating shaft 12 of the windmill 11. The other end of the rotating shaft 12 is supported by a bearing (not shown) of the wind turbine mounting member 9. Then, the generator 20 can generate electricity via the rotating shaft 12 that rotates in response to the rotation of the wind turbine 11.

Since the generator 20 is heavier than the windmill 11, it is preferable that the generator support member 18 is installed on or near the support column 5. The wind turbine 11 and the generator 20 are installed at predetermined intervals along the longitudinal direction of the snow fence 3.
The electric power generated by the generator 20 is used, for example, as a power source for a lighting fixture on a road 2 or a delineator capable of emitting light. Alternatively, the electric power generated by the generator 20 is used as a heat source for preventing freezing of the road surface of the road 2, but can be used for other purposes.

The wind power generator 1 for blizzard according to the present embodiment has the above-described configuration, and then its usage will be described.
In a snowy country or a cold region, a wind turbine mounting member 9 and a generator support member 18 are mounted at predetermined intervals on the upper end of an existing or newly installed snow fence 3, the screw portion 15 is tightened, and the push plate 16 is used to attach the snow fence 3 Fix each to the upper end.
In this state, the snow is blown up by the strong wind over the snow-covered ground surface, and the blizzard is blown onto the snow fence 3. As shown in FIGS. 1 and 2, the blizzard is blown upward from the ground surface along the snow fence 3 installed at one end of the road 2.

Due to the blizzard blown upward along the snow fence 3, each blade 13 of the wind turbine 11 in the wind power generator 1 installed at the upper end of the snow fence 3 is rotated counterclockwise in FIG. The rotation shaft 12 rotates due to the rotation of each blade 13 of the windmill 11, and the generator 20 generates electricity in response to the rotation of the rotation shaft 12. As a result, the electric power generated by the generator 20 is used, for example, as a power source for a lighting fixture on the road 2 or a delineator capable of emitting light, or as a heat source for preventing freezing of the road surface of the road 2.

As described above, according to the wind power generator 1 according to the present embodiment, the wind turbine 11 provided at the upper end of the snow fence 3 is rotated by the wind force blown up along the snow fence 3 by the ground blizzard to rotate the rotating shaft 12. It is possible to generate electricity with the generator 20 through the generator 20.
Moreover, since the wind turbine 11 is installed outside the snow fence 3, snow does not pass through the snow fence 3 and collect on the road 2.
Further, since the wind turbine 11 and the generator 20 can be installed by retrofitting the wind turbine mounting member 9 and the generator support member 18 to the existing or newly installed snow fence 3, the design cost can be installed separately from the snow fence 3. And construction costs can be reduced. Moreover, by installing the generator 20 which is heavier than the wind turbine 11 on or near the support column 5, it can be supported by the support column 5, and the snow fence 3 is not deformed or damaged.

Although the wind power generator 1 according to the embodiment of the present invention has been described in detail above, the present invention is not limited to the above-described embodiment, and appropriate changes and replacements may be made without departing from the spirit of the present invention. It is possible, and all of these are included in the present invention. Hereinafter, modifications of the present invention and the like will be described, but the description will be omitted by using the same reference numerals for the same or similar parts and members as those in the above-described embodiment.

For example, as shown in FIG. 4, for the wind turbine 11 installed on the snow fence 3 via the wind turbine mounting member 9, the wind turbine support frame 10 is projected upward from the top plate 9c of the wind turbine mounting member 9 to make the wind turbine 11 It may be installed. In this case, the rotation shaft 12 is projected above the top plate 9c by making the lower support leg 10b of the wind turbine support frame 10 longer than the upper support leg 10a. By changing the lengths of the support legs 10a and 10b of the wind turbine support frame 10, the installation height of the wind turbine 11 with respect to the snow fence 3 can be appropriately selected.
As a result, since more than half of the wind turbine 11 projects above the top plate 9c, it is possible to receive not only the wind of the blizzard along the snow fence 3 but also the crosswind flowing horizontally above the snow fence 3. Therefore, there is an advantage that the rotation speed of the wind turbine 11 is increased and the electric power of the generator 20 capable of generating electric power is increased as compared with the above-described embodiment.

Further, as another modification, the generator 20 may be installed on the ground on the road 2 side of the snow fence 3 instead of the configuration in which the generator 20 is installed in parallel with the wind turbine 11. As a result, it is not necessary to install the generator support member 18 on the girder member 8 of the snow fence 3, so that the wind turbine mounting member 9 can be installed on the support column 5, and the burden on the snow plate 6 of the snow fence 3 can be provided. Can be reduced.
Further, although the wind power generation device 1 according to the above-described embodiment is provided with the wind turbine 11 and the generator 20 using the blizzard, it is not necessarily limited to the wind power generation device 1 provided on the snow fence 3 to prevent the blizzard. Will not be done. For example, when a strong wind before or after a snowfall rises from the ground surface along the snow fence 3, the wind turbine 11 installed at the upper end of the snow fence 3 can be rotated to generate electricity with the generator 20.

When the wind turbine mounting member 9 is installed on the girder member 8 of the snow fence 3, if the weight of the wind turbine 11 is too large to withstand the snow fence 3, the snow plate 6 is removed and between the columns 5. A new support column 5 may be installed to reinforce the columns 5 by connecting them with a girder member 8.
Further, in the above-described embodiment and its modification, the snow fence 3 is composed of a support column 5 and a snow plate 6, but a hole, a gap, or the like is formed in the snow plate 6 to prevent a part of snowstorm or wind. The wind pressure that is passed through and received by the snow fence 3 may be reduced. The snow fence 3 is included in the upright wall.
