  The windmill cover 1 according to the first embodiment includes a windmill cover main body 10, a base portion 20, and a rotating portion 30. The windmill cover main body 10 includes an upper portion 10a, a middle portion 10b, and a lower portion 10c. A center fin 14 provided on the upper portion 10a, two left and right windmills 11 provided on the middle portion 10b, left and right tail fins 12 and 13, and a plurality of guides. It is comprised from the projection part 15, the projection part 16, and the windmill accommodating parts 17 and 18 on either side. The windmills 11 and 11 are provided in the windmill storage units 17 and 18. The wind turbines 11 and 11 are provided with four blade portions 11a around the rotation shafts 11b and 11b. The blade portions 11a form a blade peak portion 11d and a blade valley portion 11c along the longitudinal direction of the shaft. It is formed in a flat plate with a wave shape. The four blade portions 11a are arranged around the rotation shafts 11b and 11b at equal intervals. The windmills 11 and 11 are formed into a wave shape because a plurality of guide projections 15 described below are provided, so that the wind passing between the guide projections is efficiently received by the blade portions 11a and the rotation rate of the blades is increased. This is to mention. A position corresponding to the guide projection 15 of the blade portion 11a is a blade valley portion 11c.

  The rotating shafts 11b and 11b are provided in the windmill housing portions 17 and 18, and are rotatably supported on the upper side and the lower side of the windmill cover main body 10. A generator 40 is provided at the lower end of the rotary shafts 11b and 11b in the drawing.

When the plane is formed into a substantially elliptical shape, although not shown, a plurality of windmill storage portions are provided in parallel on both sides of the windmill cover main body 10a in parallel, and a plurality of windmill storage portions are provided. It is also possible to configure to form a pair. By providing a plurality of pairs of windmill storage units, the number of windmills increases, so that the power generation increases. Thus, the reason why the windmill cover main body 10 is formed in a substantially circular or elliptical shape is to facilitate the flow of wind coming from the front side of the windmill cover 1. Moreover, since the same effect can be expected, the windmill cover may be formed from a polygonal shape that is a substantially circular plane shape or an elliptical shape.

  In addition, the windmill cover main body 10 has a windmill cover main body middle portion 10a that is long in the vertical direction or a windmill storage portion that is short in the vertical direction, and is provided with a plurality of windmill storage portions in two stages, upper and lower, and a windmill is installed respectively. In this way, a plurality of pairs of windmill storage units can be formed.

  The windmill cover main body middle portion 10b is provided with right and left tail fins 12 and 13 so that the tips thereof face substantially in the same direction (the rear portion side in the figure). The tips of the right and left tail fins 12 and 13 have a W-shaped shape, and wind turbine covers are formed from the apex portions 12b and 12b and the valley portions 12c, 12c, 12c and 12c of the tail fins 12 and 13. Projections 12 a, 12 a, 12 a, 12 a, 12 a, 12 a having a substantially triangular cross section are formed in a straight line over a portion in contact with the main body 10.

  The windmill cover main body upper portion 10a is formed in a substantially conical shape, and is provided such that the side fins having center triangles 14 face in substantially the same direction as the tail fins 12 and 13 (the back side in the figure). Two ridges 14a, 14a having a triangular cross section are provided on a straight line between the apex portion 14b of the center fin 14 and the portion where the center fin 14 contacts the windmill cover body 10.

  Between the windmill cover main body lower portion 10c and the base portion 20, a turning portion 30 is provided that allows the windmill cover to turn freely. Although not shown, the base 20 is used by inserting a column or the like into the base 20 and fixing it, and wiring from the generator 40 to the battery is provided at an appropriate location inside or outside the column.

The operation of the windmill when the windmill cover 1 according to the first embodiment having the above configuration is used will be described.
When the wind blows from a certain direction, the tail fins 12 and 13, the center fin 14, and the protrusions 16 provided on the windmill cover 10 receive the wind, and the direction of the windmill cover 10 is changed so that the wind is easy to flow. It changes by rotating. Specifically, the protrusion 16 is on the windward side, and the tail fins 12 and 13 and the center fin 14 are on the leeward side, so that the wind is easily removed. Then, the wind coming from the front of the windmill cover will come out so as to flow along the side surface of the windmill cover main body middle part 10b. This wind is further gathered between the guide projections 15 due to the presence of the plurality of guide projections 15, and this strong wind is received by the blade crests 11d, 11d, 11d, and 11d of the wind turbine blades 11a. It is possible to obtain a stronger rotational force than when rotating with the wind as it is. Moreover, the wind which rotated the windmill 1 passes along the tail fins 12 and 13 to the rear of the windmill cover. Further, the wind that has rotated the windmill passes through the tail fins 12 and 13 and exits behind the windmill cover 1.

  According to the first embodiment, only the blade portion 11a of the windmill receiving wind necessary for rotation is exposed from the windmill cover 1 and the other portions are not exposed. There is a reduced risk that a bird will come into contact with the windmills 11 and 11 and the windmills 11 and 11 may be damaged, or that the child may touch the windmills 11 and 11 and be injured. In addition, power generation efficiency is improved because power is generated by a plurality of windmills. Moreover, since the several guide projection part 15 was provided along the windmill accommodating parts 17 and 18, the windmills 11 and 11 can also receive a wind efficiently.

  The windmill cover 100 according to the second embodiment includes a windmill cover main body 110 installed on a wall surface of a building, a windmill storage portion 120 provided on the windmill cover main body 110, and five guide protrusions 140. The windmill housing 120 is provided with a windmill 130 provided with four blade portions 130a around the rotation shaft 130b. The blade portion 130a is formed in a flat plate shape having a wave shape that forms a blade peak portion 130c and a blade valley portion 130d along the longitudinal direction of the rotating shaft 130b. The four blade portions 130a are arranged at equal intervals around the rotation shaft 130b. The rotating shaft 130b is provided in the windmill storage unit 120. The windmill storage part 120 is formed so that the blade part 130a does not touch the inside even if the windmill 130 rotates inside. Although the shape is formed in a semi-cylindrical shape in the figure, the shape is not particularly limited as long as the windmill 11 can rotate.

  As shown in FIGS. 6 and 7, the windmill cover according to the second embodiment is installed in a place where wind blows from a certain direction such as a wall surface of a building.

The operation of the windmill when the windmill cover 100 according to the second embodiment having the above configuration is used will be described.
When the wind blows upward from the lower direction in FIGS. 6 and 7, the wind flows from the lower side to the upper side along the windmill cover body 110, and the wind is collected between the guide protrusions 140 by the five guide protrusions 140. It flows strongly. Therefore, the wind that has passed between the guide protrusions 140 strongly hits the blade crest portion 130c of the blade portion 130a, and the windmill 130 rotates. Therefore, it is possible to obtain a stronger rotational force than when rotating with the wind as it is.

  According to the second embodiment, only the blade portion 130a of the windmill 130 that receives wind necessary for rotation is exposed from the windmill cover 100 and the other portions are not exposed. During power generation, the risk of birds touching the windmill and damaging the windmill is reduced. In addition, since the plurality of guide protrusions 140 are provided along the windmill storage unit 120, the windmill 130 can receive wind efficiently.

  The present invention can be modified in design without departing from the scope of claims for utility model registration, and is not limited to the above embodiment.
