Description

The present disclosure relates to a wind power generation device for a vehicle and a freight vehicle.

There is a freight vehicle (truck) equipped with a wind power generator for a vehicle (for example, see Patent Document 1). The wind power generation device for a vehicle disclosed in Patent Document 1 is installed on the passenger compartment of a freight vehicle. This wind power generation device for a vehicle has a rotor blade that rotates in response to the wind from the vehicle.

International Publication No. 2022/269938

In the vehicle wind power generation device disclosed in Patent Document 1, there is room for further improvement in order to increase power generation efficiency.

The present disclosure takes the above facts into consideration and aims to improve power generation efficiency in a vehicle wind power generation device installed above the passenger compartment of a freight vehicle.

A wind power generation device for a vehicle according to a first aspect includes a wind turbine, a storage chamber that rotatably accommodates the wind turbine about a rotation axis along the width direction, and a storage chamber that is located forward of the storage chamber, and It has an air supply port that takes air into the storage chamber, and an exhaust port that is located behind the storage chamber and above the air supply port and discharges the air in the storage chamber upward. a casing installed above a passenger compartment of a vehicle; and a rectifying blade provided on the casing, arranged above the exhaust port, and curved convexly downward when viewed from the width direction of the casing. , is provided.

According to the above aspect, the housing is installed on the passenger compartment of the freight vehicle with the air supply port facing forward. When the freight vehicle runs in this state, negative pressure is created in the storage chamber by the wind flowing above the exhaust port, and the air in the storage chamber is discharged upward from the exhaust port, and the air is discharged from the air supply port into the storage chamber. The wind (air) from the vehicle is taken in by the vehicle. At this time, the wind turbine receives the traveling wind and rotates about a rotation axis along the width direction of the housing. The rotation of this wind turbine can be used to generate electricity.

Further, the housing is provided with a rectifying blade. The straightening vane is arranged above the exhaust port. When the freight vehicle travels, the wind flowing along the top surface of the housing passes above and below the rectifying blades.

Here, the straightening blade is curved downward in a convex shape when viewed from the width direction of the housing. As a result, the traveling wind passing under the straightening blade flows along the curved lower surface of the straightening blade due to the Coanda effect, and heads diagonally upward from the rear end of the straightening blade. As a result, a negative pressure is created on the lower surface side of the straightening blade, that is, near the exhaust port, and the traveling wind inside the accommodation chamber is pulled diagonally upward from the exhaust port.

Therefore, the exhaust efficiency of the running air that passes through the accommodation chamber and is discharged from the exhaust port is increased. As a result, the supply efficiency of the traveling air supplied from the air supply port to the storage chamber is also increased. Therefore, since the rotational efficiency of the wind turbine is increased, power generation efficiency can be increased.

Furthermore, by covering the exhaust port from above with the rectifying blade, for example, rain or snow is suppressed from entering the storage chamber through the exhaust port. Furthermore, even if the wind turbine were to come off the housing while the freight vehicle is traveling, the wind turbine would interfere with the rectifier blades, so the wind turbine would be prevented from falling.

A wind power generation device for a vehicle according to a second aspect is the wind power generation device for a vehicle according to the first aspect, in which the exhaust port is formed on the upper surface of the housing, and the front end portion of the straightening blade is It is located forward of the front edge and above the upper surface of the housing.

According to the above aspect, the exhaust port is formed on the top surface of the housing. Further, the front end of the straightening blade is located forward of the front edge of the exhaust port and above the top surface of the casing. Thereby, the traveling wind discharged from the exhaust port is suppressed from going beyond the front end of the straightening blade to the upper surface side of the straightening blade. Therefore, the efficiency of exhausting the traveling air discharged from the exhaust port is further improved.

A wind power generator for a vehicle according to a third aspect is the wind power generator for a vehicle according to the second aspect, in which the upper surface of the casing is curved downward from the front edge of the exhaust port toward the front.

According to the above aspect, the upper surface of the housing curves downward from the front edge of the exhaust port toward the front. As a result, when the freight vehicle travels, the traveling wind flows obliquely upward along the upper surface of the casing. Therefore, the air resistance of the housing is reduced.

Further, the traveling wind flowing obliquely upward along the upper surface of the housing passes above and below the rectifying blades. In other words, the wind flowing along the top surface of the housing is collected by the rectifier blades. This increases the amount of traveling air that passes above and below the rectifying blades, making it easier for the traveling air in the accommodation chamber to be pulled diagonally upward from the exhaust port, as described above. Therefore, the efficiency of exhaust air from the exhaust port is further increased, and the efficiency of air supply from the air supply port is further increased.

In the vehicle wind power generation device according to a fourth aspect, in the vehicle wind power generation device according to the third aspect, side wall portions on both sides of the casing each have a protrusion that protrudes upward from the top surface of the casing. .

According to the above aspect, the side wall portions on both sides of the casing each have a protrusion that projects upward from the top surface of the casing.

Here, when the freight vehicle runs, the traveling wind that flows diagonally upward along the top surface of the casing becomes faster than the traveling wind that flows backward along the side of the casing, and the air pressure on the top surface of the casing increases. The air pressure is lower than that on the sides of the body. As a result, a vortex is generated that wraps around from the side surface of the casing to the top surface, potentially increasing the air resistance of the casing.

In contrast, in this aspect, as described above, the side wall portion of the casing has a protrusion that protrudes upward from the top surface of the casing. This protrusion prevents air from going around from the side surface to the top surface of the housing. As a result, the generation of vortices that wrap around from the side surface to the top surface of the housing is suppressed. Therefore, the air resistance of the housing is reduced.

A vehicle wind power generation device according to a fifth aspect is the vehicle wind power generation device according to the fourth aspect, in which the protrusion extends from the front end side to the rear end side on the upper surface of the casing.

According to the above aspect, the protrusion extends from the front end side to the rear end side on the upper surface of the housing. This suppresses the generation of vortices that extend from the front end side to the rear end side of the top surface of the casing and wrap around from the side surface side to the top surface side of the casing when the freight vehicle is traveling. Therefore, the air resistance of the housing is further reduced.

A wind power generation device for a vehicle according to a sixth aspect is the wind power generation device for a vehicle according to the fourth aspect, in which the rectifying blades are spanned over the protrusions on both sides.

According to the above aspect, the rectifying blade spans the protrusions on both sides. Since the rigidity of the protruding portion is increased by the straightening blades, vibrations of the protruding portion due to traveling of the freight vehicle are suppressed.

An angle adjustment mechanism is provided that rotatably supports the rectifier blade and holds the baffle at a predetermined rotation angle.

According to the above aspect, the casing is provided with an angle adjustment mechanism. The angle adjustment mechanism supports the flow straightening blade so as to be rotatable about a rotation axis along the width direction of the housing, and holds the flow straightening blade at a predetermined rotation angle. This angle adjustment mechanism reduces the air resistance of the loading platform by adjusting the rotation angle of the straightening blade so that, for example, the rear end of the straightening blade is at the same height as the top surface of the loading platform of the cargo vehicle. be able to.

A wind power generation device for a vehicle according to an eighth aspect is the wind power generation device for a vehicle according to the first aspect, in which a rear end portion of the straightening blade is located above a front end portion of the straightening blade.

According to the above aspect, the rear end portion of the flow straightening blade is located above the front end portion of the flow straightening blade. As a result, when the freight vehicle is traveling, the traveling wind passing under the straightening blade tends to flow diagonally upward from the rear end of the straightening blade. Therefore, the efficiency of exhaust air from the exhaust port is further increased, and the efficiency of air supply from the air supply port is further increased.

A wind power generation device for a vehicle according to a ninth aspect is the wind power generation device for a vehicle according to the first aspect, in which the casing has a partition wall portion that partitions the storage chamber into a plurality of divided storage chambers in the width direction of the casing.

Here, the front end side of the partition wall portion is tapered toward the front in a plan cross-sectional view. As a result, when the freight vehicle is running, the wind supplied from the air supply port to the storage chamber is guided by the front end of the partition wall to the wind turbines housed in the divided storage chambers on both sides of the partition wall. be done. Therefore, the rotational efficiency of the wind turbine is further increased.

Further, the rear end side of the partition wall portion is tapered toward the rear in a plan cross-sectional view. As a result, when the freight vehicle is traveling, the traveling wind can easily flow from the divided storage chambers on both sides of the partition wall toward the exhaust port. Therefore, the rotational efficiency of the wind turbine is further increased.

(Partition wall)
As shown in FIG. 5, the storage chamber 40 is provided with a partition wall portion 50. As shown in FIG. The partition wall portion 50 is arranged along the front-rear direction. The partition wall 50 divides the storage chamber 40 into a plurality of (two in this embodiment) divided storage chambers 40E in the width direction of the housing 30.

Wind turbines 70, which will be described later, are each accommodated in the plurality of divided accommodation chambers 40E. The front end side of the partition wall portion 50 is a front tapered portion 50F that tapers toward the front in a plan cross-sectional view. As a result, when the freight vehicle 10 is traveling, the traveling wind W supplied from the air supply flow path 42 to the partition wall 50 is transferred to both sides of the partition wall 50 by the front tapered portion 50F, as shown by the arrow a1. The wind turbines 70 are respectively guided to the wind turbines 70 housed in the divided housing chambers 40E.

Furthermore, air supply guide portions 52 are provided on the pair of side wall portions 36 of the housing 30, respectively.

In addition, the side wall portions 36 on both sides of the housing 30 are arranged at a predetermined angle θ toward the outside in the width direction of the housing 30 (arrow Y side) toward the rear with respect to the front-rear direction of the housing 30 in a plan cross-sectional view. It is sloping. As a result, the cross-sectional areas of the air supply flow path 42, the storage chamber 40, and the exhaust flow path 46 increase toward the rear. Therefore, when the freight vehicle 10 travels, the traveling wind W easily passes through (easily escapes) the air supply flow path 42, the storage chamber 40, and the exhaust flow path 46.

A generator 60 is housed inside the partition wall 50 . Further, rotating shafts 72 of a pair of wind turbines 70 are respectively connected to the generator 60. This generator 60 generates power as the pair of wind turbines 70 rotate. That is, the generator 60 converts the rotational energy of the pair of wind turbines 70 into electrical energy. Further, a battery (not shown) or the like that stores the power generated by the generator 60 is connected to the generator 60 .

Note that the housing 30 may be provided with a plurality of partition wall sections 50. Further, the partition wall portion 50 may be omitted. Furthermore, the generator 60 is not limited to being housed inside the partition wall 50, but may be housed in another part of the housing 30, or may be installed in the vehicle body 12 of the freight vehicle 10, for example.

(wind turbine)
The wind turbine 70 is a windmill that rotates around a rotating shaft 72 along the width direction of the housing 30. This wind turbine 70 has a rotating shaft 72, a pair of side bases 74, and a plurality of rotary blades 76. The pair of side bases 74 face each other in the width direction of the housing 30.

The central portion 74A is formed in a circular shape when viewed from the width direction of the housing 30. The plurality of support arm portions 74B extend radially outward from the outer periphery of the central portion 74A around the rotating shaft 72 when viewed from the width direction of the housing 30. The rotary blades 76 are bridged over the support arm portions 74B of the pair of side bases 74, respectively.

The plurality of rotary blades 76 rotate about the rotation shaft 72 by receiving the traveling wind W supplied from the air supply port 44 through the air supply flow path 42 . At this time, each rotor blade 76 rotates so that the rotor blade 76 located in front of the rotary shaft 72 passes below the rotary shaft 72 and heads toward the rear of the rotary shaft 72, as shown by arrow P. .

Each rotor blade 76 is hollow and made of metal, resin, or the like. Further, the cross-sectional shape of each rotary blade 76 is a blade shape that generates a lift force directed outward in the radial direction of the rotary shaft 72 with respect to wind supplied from the front in the rotation direction.

Specifically, the outer surface 76S1 of each rotary blade 76 is a curved surface that curves convexly forward in the rotation direction. On the other hand, the inner surface 76S2 of each rotor blade 76 is a curved surface that curves convexly forward in the rotation direction. The curvature of the inner surface 76S2 of the rotor blade 76 is smaller than the curvature of the outer surface 76S1 of the rotor blade 76. As a result, a lift force directed outward in the radial direction of the rotary shaft 72 is generated in each rotary blade 76 with respect to the wind supplied from the front in the rotation direction.

A plurality of recesses 78 are formed on the outer surface 76S1 of each rotary blade 76 to receive the traveling wind W supplied from the air supply flow path 42. These recesses 78 make it easier for the rotor blade 76 to rotate in the direction of arrow P.

Note that the number and arrangement of the recesses 78 can be changed as appropriate. Further, the recess 78 may be omitted. Further, the number, arrangement, shape, etc. of the rotary blades 76 can be changed as appropriate.

(straightening blade)
The housing 30 is provided with a rectifying blade 80. The rectifying blade 80 rectifies the traveling wind W that flows upward (upward and backward) along the upper surface 34U of the housing 30 and passes above the exhaust port 48 when the freight vehicle 10 is traveling. This is a wing that increases exhaust efficiency.

The straightening blade 80 is arranged above the exhaust port 48 and covers the front side of the exhaust port 48 from above. The rectifying blade 80 spans over the protruding portions 36A on the side wall portions 36 on both sides of the housing 30. Further, the upper end side of the protruding portion 36A of the side wall portion 36 protrudes upward from the upper surface 80U of the straightening blade 80. Note that the range in which the straightening blades 80 cover the exhaust port 48 from above can be changed as appropriate.

The front end portion 80F of the straightening blade 80 is located above the upper surface 34U of the housing 30. As a result, when the freight vehicle 10 is traveling, the traveling wind W flowing obliquely upward (upward and backward) along the upper surface 34U of the housing 30 passes above and below the rectifier blades 80.

The front end portion 80F of the straightening blade 80 is located forward of the front edge portion 48F of the exhaust port 48. Thereby, the traveling wind W discharged from the exhaust port 48 is suppressed from going around from the front end portion 80F of the straightening blade 80 to the upper surface 80U side of the straightening blade 80.

The straightening blades 80 are curved downward in a convex shape when viewed from the width direction of the housing 30. Specifically, the upper surface 80U and lower surface 80L of the straightening blade 80 are curved surfaces that curve downward in a convex shape. As a result, when the freight vehicle 10 is traveling, the traveling wind W passing under the straightening blade 80 flows along the lower surface 80L of the straightening blade 80 due to the Coanda effect, and is directed diagonally upward from the rear end portion 80R of the straightening blade 80. . Further, the rear end portion 80R of the straightening blade 80 is located above the front end portion 80F of the straightening blade 80. This makes it easier for the traveling wind W passing under the straightening blade 80 to head obliquely upward from the rear end portion 80R of the straightening blade 80.

Note that the position of the rear end portion 80R of the flow straightening blade 80 is not limited to being above the front end portion 80F of the flow straightening blade 80, and may be at the same height as the front end portion 80F of the flow straightening blade 80, for example.

(opening/closing plate)
The housing 30 is provided with an opening/closing plate 90. The opening/closing plate 90 is formed into a plate shape that can open and close the air supply port 44, and is disposed within the air supply flow path 42 of the housing 30. A lower end portion of the opening/closing plate 90 is rotatably supported by the housing 30 via a rotation shaft 92. The rotation shaft 92 is disposed along the width direction of the housing 30 and is supported by the side walls 36 on both sides of the housing 30.

The opening/closing plate 90 rotates around the rotation axis 92 toward the accommodation chamber 40 from a closed state in which the air supply port 44 is closed, as shown by a chain double-dashed line, and from a closed state, as shown in a solid line. It is possible to change to an open state in which the air supply port 44 is opened. This opening/closing plate 90 is inclined with respect to the floor surface 40B of the air supply flow path 42 in the open state.

More specifically, when the open state of the opening/closing plate 90 is viewed from the width direction of the housing 30, the opening/closing plate 90 is inclined upward toward the rear with respect to the floor surface 40B of the air supply flow path 42. As a result, the running wind W supplied from the air supply port 44 to the air supply flow path 42 flows diagonally upward (upward and backward) along the upper surface 90U of the opening/closing plate 90 in the open state, as shown by arrow a3. . Note that the opening/closing plate 90 may be omitted.

(effect)
Next, the operation of this embodiment will be explained.

(straightening blade)
First, while explaining the operation of the vehicle wind power generator 20, the action of the rectifier blades will be explained.

FIG. 4 shows a vehicle wind power generation device 20 installed on the upper surface 14U (see FIG. 1) of the passenger compartment 14 of the freight vehicle 10. The vehicle wind power generation device 20 is installed with the air supply port 44 facing forward. Further, the opening/closing plate 90 of the vehicle wind power generator 20 is in an open state.

When the freight vehicle 10 travels (moves forward) in this state, a negative pressure is generated in the exhaust flow path 46 by the traveling wind W flowing above the exhaust port 48, and the air in the accommodation chamber 40 flows through the exhaust flow path 46 to the exhaust port. 48 and is discharged diagonally upward (upward and backward). As a result, the traveling wind W is taken into the accommodation chamber 40 from the air supply port 44 via the air supply flow path 42. At this time, the plurality of rotary blades 76 of the wind turbine 70 receive the traveling wind W and rotate in the direction of arrow P about the rotary shaft 72. As these rotary blades 76 rotate, the generator 60 generates electricity. The power generated by the generator 60 is supplied to, for example, a battery (not shown).

Further, when the freight vehicle 10 travels, the traveling wind W flows obliquely upward along the upper surface 34U of the housing 30 and passes above and below the rectifier blades 80. Here, the straightening blade 80 is curved downward in a convex shape when viewed from the width direction of the housing 30.

Thereby, the traveling wind W passing under the straightening blade 80 flows along the curved lower surface 80L of the straightening blade 80 due to the Coanda effect, and heads obliquely upward from the rear end portion 80R of the straightening blade 80. As a result, the lower surface side of the straightening blade 80, that is, the vicinity of the exhaust port 48 becomes negative pressure, and the traveling wind W in the storage chamber 40 and the exhaust flow path 46 is pulled rearward.

Therefore, the exhaust efficiency of the traveling wind W discharged from the exhaust port 48 is increased. As a result, the supply efficiency of the traveling wind W supplied from the air supply port 44 to the storage chamber 40 is also increased. Therefore, since the rotational efficiency of the wind turbine 70 is increased, power generation efficiency can be increased.

Further, the rear end portion 80R of the flow straightening blade 80 is located above the front end portion 80F of the flow straightening blade 80. Thereby, when the freight vehicle 10 travels, the traveling wind W passing under the straightening blade 80 tends to flow diagonally upward from the rear end portion 80R of the straightening blade 80. Therefore, the exhaust efficiency from the exhaust port 48 is further improved.

Further, the front end portion 80F of the straightening blade 80 is located forward of the front edge portion 48F of the exhaust port 48 and above the upper surface 34U of the housing 30. Thereby, the traveling wind W discharged from the exhaust port 48 is suppressed from going beyond the front end portion 80F of the straightening blade 80 to the upper surface 80U side of the straightening blade 80. Therefore, the exhaust efficiency of the running wind W discharged from the exhaust port 48 is further improved.

The airfoil 80 also covers the exhaust port 48 from above. This prevents, for example, rain or snow from entering the accommodation chamber 40 through the exhaust port 48. Furthermore, even if the wind turbine 70 becomes detached from the housing 30 while the freight vehicle 10 is traveling, the wind turbine 70 interferes with the airfoil 80, preventing the wind turbine 70 from falling.

Further, the upper surface 34U of the housing 30 is a curved surface that curves downward toward the front. Thereby, when the freight vehicle 10 travels, the traveling wind flows obliquely upward along the upper surface 34U of the housing 30. Therefore, the air resistance of the housing 30 is reduced.

Further, the traveling wind W flowing obliquely upward along the upper surface 34U of the housing 30 passes above and below the rectifying blades 80. That is, the traveling wind W flowing along the upper surface 34U of the casing 30 is collected by the rectifier blades 80. This increases the amount of traveling wind W passing above and below the straightening blades 80, so that the traveling wind W in the accommodation chamber 40 is more likely to be pulled obliquely upward from the exhaust port 48, as described above. Therefore, the efficiency of exhaust air from the exhaust port 48 is further increased, and the efficiency of air supply from the air supply port 44 is further increased.

Further, as shown in FIG. 2, the side walls 36 on both sides of the casing 30 each have a protrusion 36A that protrudes upward from the top surface 34U of the casing 30.

Here, when the freight vehicle 10 travels, the flow velocity of the traveling wind W flowing obliquely upward along the upper surface 34U of the housing 30 is faster than the flow velocity of the traveling wind W flowing backward along the side surface 36S of the housing 30. Therefore, the air pressure on the upper surface 34U side of the casing 30 is lower than the air pressure on the side surface of the casing 30. As a result, a vortex may be generated that wraps around from the side surface 36S side of the housing 30 to the top surface 32U side, and air resistance may increase.

In contrast, in this embodiment, as described above, the side wall portion 36 of the housing 30 has the protruding portion 36A that protrudes upward from the upper surface 34U of the housing 30. This protrusion 36A prevents air from going around from the side surface 36S side of the housing 30 to the top surface 32U side, as shown by arrow V. As a result, the generation of vortices that wrap around from the side surface 36S side to the top surface 32U side of the housing 30 is suppressed, so that the air resistance of the housing 30 is reduced.

Further, the protruding portion 36A extends from the front end side to the rear end side of the upper surface 34U of the housing 30. Thereby, when the freight vehicle 10 travels, the generation of vortices that wrap around from the side surface 36S side of the housing 30 to the upper surface 32U side are suppressed from the front end side to the rear end side of the upper surface 34U of the housing 30. Therefore, the air resistance of the housing 30 is further reduced.

Further, the rectifying blade 80 spans the protrusion portions 36A on both sides. Since the rigidity of the protrusion 36A is increased by the straightening blade 80, vibrations and the like of the protrusion 36A caused by traveling of the freight vehicle 10 are suppressed. Furthermore, the protrusion 36A suppresses generation of blade tip vortices at the ends of the straightening blades 80.

(containment room)
Next, the function of the storage chamber 40 will be explained.

As shown in FIG. 5, the housing chamber 40 of the housing 30 is provided with a partition wall portion 50. As shown in FIG. The partition wall portion 50 partitions the storage chamber 40 into a plurality of divided storage chambers 40E in the width direction of the housing 30. A wind turbine 70 is accommodated in each of these divided accommodation chambers 40E.

The front end side of the partition wall portion 50 is a front tapered portion 50F that tapers toward the front in a plan cross-sectional view. As a result, when the freight vehicle 10 is traveling, the traveling wind W supplied to the accommodation chamber 40 is divided into both sides of the partition wall 50 by the front tapered portion 50F of the partition wall 50, as shown by the arrow a1. They are each guided to the wind turbine 70 housed in the housing chamber 40E. Therefore, the rotational efficiency of the wind turbine 70 is increased.

Further, air supply guide portions 52 are provided on the side wall portions 36 on both sides of the housing 30. The air supply guide portion is located forward of the storage chamber 40 and is inclined rearward and inward in the width direction of the housing 30 in a plan cross-sectional view.

As a result, when the freight vehicle 10 is traveling, the traveling wind W supplied from the air supply port to the accommodation chamber 40 along the side walls on both sides of the housing 30 is controlled by the air supply guide section as shown by the arrow a2. The wind turbine 70 is guided inside the housing 30 in the width direction, that is, the wind turbine 70 is housed in the housing chamber 40 . Therefore, the rotational efficiency of the wind turbine 70 is further increased.

Next, the rear end side of the partition wall portion 50 is formed into a rear tapered portion 50R that tapers toward the rear in a plan cross-sectional view. Thereby, when the freight vehicle 10 is traveling, the traveling wind W tends to flow from the divided accommodation chambers 40E on both sides of the partition wall portion 50 toward the exhaust port 48. Therefore, the rotational efficiency of the wind turbine 70 is further increased.

In addition, the side walls 36 on both sides of the storage chamber 40 are inclined at a predetermined angle θ toward the rear and outward in the width direction of the housing 30 in the front-to-rear direction in a planar cross-sectional view. This makes it easier for the running wind W to flow from the storage chamber 40 toward the exhaust port 48 when the freight vehicle 10 is traveling. This further increases the rotation efficiency of the wind turbine 70.

Furthermore, a generator 60 that generates power as the wind turbine 70 rotates is provided inside the partition wall 50 . By accommodating the generator 60 inside the partition wall portion 50 in this manner, the casing 30 can be made smaller.

(opening/closing plate)
Next, the function of the opening/closing plate 90 will be explained.

As shown in FIG. 4, the housing 30 is provided with an opening/closing plate 90 that opens and closes the air supply port 44. As shown in FIG. The opening/closing plate 90 is rotatably supported by the housing 30 at a lower end thereof about a rotation shaft 92 extending in the width direction of the housing 30 . This opening/closing plate 90 is tilted with respect to the floor surface 42B of the air supply flow path 42 in an open state in which the air supply port 44 is opened by being rotated toward the accommodation chamber 40 side.

Here, when the traveling wind W flows along the floor surface 40B of the air supply flow path 42 while the freight vehicle 10 is traveling, air resistance increases due to friction with the floor surface 40B and the like.

In contrast, in this embodiment, as described above, the opening/closing plate 90 is inclined with respect to the floor surface 40B of the air supply flow path 42 in the open state. As a result, when the freight vehicle 10 is traveling, the traveling wind W supplied to the air supply flow path 42 flows obliquely upward along the opening/closing plate 90 as shown by arrow a3, and from the floor surface of the air supply flow path 42. move away upwards. Therefore, air resistance such as friction generated between the running wind W and the floor surface 40B is reduced.

Further, in the closed state in which the air supply port 44 is closed by the opening/closing plate 90, snow, foreign objects, etc. are prevented from entering the storage chamber 40 from the air supply port 44. Therefore, damage to the wind turbine 70, etc. is suppressed.

(Modified example)
Next, a modification of the above embodiment will be described.

In the modification shown in FIG. 6, the housing 30 is provided with an angle adjustment mechanism 100 that adjusts the rotation angle of the straightening blades 80. The angle adjustment mechanism 100 has a rotation shaft 102 and a fixture (not shown).

The rotation shaft 102 is provided integrally with the front end portion 80F of the straightening blade 80. The rotation shaft 102 is disposed along the width direction of the housing 30 and is rotatably supported by the protrusions 36A on both sides of the housing 30. Thereby, the straightening blade 80 is allowed to rotate around the rotation axis 102.

Further, both ends of the rotation shaft 102 pass through through holes (not shown) formed in the protrusions 36A on both sides of the housing 30. Male threaded portions (not shown) are provided at both ends of the rotating shaft 102, respectively. A pair of nuts is attached to each male threaded portion. By sandwiching the protrusion 36A from both sides with the pair of nuts, rotation of the rotation shaft 102 with respect to the protrusion 36A is restricted, and the rectifying blade 80 is held at a predetermined rotation angle.

Here, for example, depending on the type of freight vehicle 10, the height of the upper surface 16U of the cargo compartment 16 may differ. In such a case, in this modification, for example, the angle adjustment mechanism 100 adjusts the straightening blade 80 so that the rear end portion 80R of the straightening blade 80 is at the same height as the upper surface 16U of the cargo compartment 16 of the freight vehicle 10. Adjust the rotation angle. Thereby, air resistance on the front surface 16F of the luggage compartment 16 can be reduced. Therefore, the versatility of the vehicle wind power generation device 20 is improved.

Next, in the modification shown in FIGS. 7 and 8, the vehicle wind power generation device 20 includes an outdoor unit 110 for air conditioning. As shown in FIG. 7, the outdoor unit 110 is connected, for example, to an indoor unit 112 disposed in the passenger compartment 14, and forms a refrigeration cycle (cooling cycle) together with the indoor unit 112.

A control unit 114 (see FIG. 8) is connected to the outdoor unit 110 and the indoor unit 112. The control unit 114 controls the operation of the outdoor unit 110 and the indoor unit 112. For example, a battery 116 provided in the vehicle body 12 of the freight vehicle 10 is connected to the outdoor unit 110, the indoor unit 112, and the control unit 114.

The outdoor unit 110 is arranged on the upper surface 14U of the passenger compartment 14 and on the rear side of the housing 30. Specifically, the housing 30 has an equipment room 120. The equipment chamber 120 is arranged behind the storage chamber 40 and below the exhaust flow path 46. Furthermore, the equipment room 120 is partitioned by a lower wall 32, a pair of side walls 36, and a rear wall 38 of the housing 30.

A pair of side wall portions 36 in the equipment room 120 are formed with air supply ports 124 that take in air (outside air) into the equipment room 120 . Further, an opening 122 is formed in the rear wall portion 38 of the equipment room 120. The outdoor unit 110 is arranged in this opening 122.

The outdoor unit 110 is attached to a stay 18 attached to the outer surface of the rear wall of the passenger compartment 14. Thereby, the load of the outdoor unit 110 does not act on the upper surface 14U of the passenger compartment 14, or the load of the outdoor unit 110 acting on the upper surface 14U of the passenger compartment 14 is reduced.

The outdoor unit 110 is disposed with the air outlet 110A facing rearward, and faces the front surface 16F of the luggage compartment 16. Further, the air outlet 110A of the outdoor unit 110 is arranged outside the equipment room 120. On the other hand, the air inlet 110B of the outdoor unit 110 is arranged inside the equipment room 120.

By installing the outdoor unit 110 in the equipment room 120 that utilizes the space below the exhaust flow path 46 in this manner, it is possible to downsize the vehicle wind power generation device 20.

Furthermore, by supporting the outdoor unit 110 by the stay 18 attached to the outer surface of the rear wall of the passenger compartment 14, the load on the upper surface 14U of the passenger compartment 14 can be reduced.
