  For example, Patent Document 1 discloses that a wind power generator is mounted on the body of an automobile.

JP 2007-32550 A

Although not limited to the above-mentioned Patent Document 1, there are many ideas for mounting a windmill in an automobile to generate electric power, but there is no convincing explanation about its practicality.
In other words, automobiles have a wide gap in running speed from low-speed driving in urban areas to high-speed driving on highways, and the windmill itself has poor power generation efficiency at low wind speeds, and overspeeding in high-speed winds. There are various problems such as the possibility of damage.
An object of the present invention is to provide a power generation vehicle that has a simple structure, is safe, and can easily and strongly generate power even when traveling at a low speed.

  The specific contents of the present invention are as follows. In the present invention, the power generation vehicle is a generic term for self-propelled vehicles such as automobiles and on-orbit vehicles such as trains, and non-self-propelled vehicles such as trailers.

(1) A power generation vehicle in which an air guide slope is formed in the rear part of the body from the front upper part to the rear lower part, and a propeller windmill for driving the power generator is arranged in the rear part.

(2) The power generation vehicle according to (1), wherein an air guide hood having front and rear openings is disposed at the rear portion of the body so as to surround the propeller windmill.

(3) The power generation vehicle according to (1) or (2), wherein the rear bottom surface of the air guide slope portion is a bottom slope inclined upward from the front lower portion toward the propeller.

(4) The air guide hood is formed of an upper plate and left and right side plates, the outer surface is flat, and the inner side surface is formed with a thicker front edge and gradually thinner toward the rear edge (2). Or the electric power generating vehicle as described in (3).

(5) The power generation vehicle according to any one of (2) to (4), wherein the upper plate of the air guide hood has a front edge positioned above the ceiling plate of the body and is inclined downward.

(6) The power generation vehicle according to any one of (2) to (5), wherein an upper plate rear end portion of the air guide hood is curved upward.

(7) The power generation vehicle according to any one of (2) to (6), wherein a solar power generation panel is stretched on an outer surface of the air guide hood.

(8) The power generation vehicle according to any one of (1) to (7), wherein the propeller windmill is configured to be tiltable forward together with the support.

(9) The flow rate adjusting door is mounted between the front edge of the air guide hood and the body, and the amount of inflow air adapted to the speed of the power generation vehicle is controlled. The power generation vehicle according to any one of the above.

(10) The power generation vehicle according to (9), wherein the flow rate adjusting door is opened and closed by computer control in accordance with a traveling speed.

(11) The propeller windmill has a curved portion with a tip bent from the largest chord length portion of the blade toward the body, and the front surface of the curved portion of the lower blade is opposed to the extension line of the air guide slope (1) The power generation vehicle according to any one of (10) to (10).

  The present invention has the following effects.

  In the power generation vehicle described in (1), the air guide slope is formed in the rear part of the body from the front upper part to the rear lower part, and the propeller windmill is disposed in the rear part thereof. The airflow flowing along the body strongly hits the rear propeller windmill without diffusing on the air guide slope due to the Coanda effect, and can efficiently generate power even when the automobile is traveling at a low speed. Since the propeller windmill is arranged at the rear part of the body, the propeller can be increased and the amount of power generation can be increased within a range that does not hinder the traveling.

  In the power generation vehicle described in (2) above, since the air guide hood is disposed so as to cover the propeller windmill, the airflow flowing along the air guide slope from the upper surface of the body is diffused in the lateral direction. Without being guided to a propeller wind turbine, it is possible to generate power efficiently.

  In the power generation vehicle according to (3), the rear bottom surface of the air guide slope portion is a bottom slope inclined upward from the front lower portion toward the propeller, and therefore flows along the bottom surface as the vehicle travels. The airflow flows rearward and upward on the bottom slope, hits the propeller, and its rotational efficiency is increased.

  In the power generation vehicle described in (4), the outer surface of the upper plate and the left and right side plates of the air guide hood are flat, and the inner surface is formed with a thicker front edge and gradually thinner toward the rear edge. The airflow passing along the inner surface of the air hood becomes high speed due to the Coanda effect and flows toward the propeller to increase the rotation efficiency.

  In the power generation vehicle described in (5) above, since the front edge of the upper plate in the air guide hood protrudes above the ceiling plate of the body, it is ensured that the airflow flowing along the upper surface of the body during traveling is propeller. Can lead to a windmill.

  In the power generating vehicle described in (6) above, the upper plate rear end portion of the air guide hood is curved upward, so that the air guide hood and the vehicle body are prevented from rising during high speed travel.

  In the power generation vehicle described in (7) above, since the solar power generation panel is stretched on the outer surface of the air guide hood, it can be generated and stored by the sun during parking.

  In the power generation vehicle described in (8) above, since the propeller windmill can be tilted forward together with the support, if the propeller windmill is tilted forward during high-speed traveling, the amount of airflow hitting the front surface of the propeller is small. Therefore, the propeller windmill will not over-rotate.

  In the power generation vehicle described in (9) above, since a flow rate adjusting door is installed between the front edge of the air guide hood and the body, and the air volume control suitable for the speed of the power generation vehicle can be performed, the vehicle travels at a low speed. When the vehicle is traveling at a high speed, the propeller can be prevented from over-rotating by closing the flow rate adjusting door according to the speed.

  In the power generation vehicle described in (10) above, the flow rate adjusting door is opened and closed by computer control according to the speed, so that it can travel with peace of mind even when entering the expressway from a normal road.

  In the power generation vehicle described in (11), the front end of the blade is bent toward the body from the maximum chord length of the blade, and the front surface of the lower bent portion of the blade faces the extended line of the air guide slope. Therefore, the airflow flowing along the air guide slope hits the curved portion of the blade, and the rotation direction ratio is increased.

It is the side view which cut off a part of Example 1 of the power generation vehicle concerning the present invention. It is the top view which similarly cut off a part of electric power generation vehicle. It is a rear view of the power generation vehicle. It is a top view of the propeller windmill in a power generation vehicle similarly. It is a principal part side view of Example 2 of a power generation vehicle similarly. It is a flow control door part enlarged side view. It is a principal part side view of Example 3 of a power generating vehicle. It is a side view of Example 4 of a power generating vehicle.

  A first embodiment of the present invention will be described with reference to the drawings. The power generation vehicle 1 is an automobile, and an air guide slope 2 that is largely inclined from the front upper part to the rear lower part is formed at the rear part of the body 1A in a side view. At the rear part of the air guide slope 2, a support column 4 is erected on the upper rear end of the frame 3, and a propeller wind turbine 5 facing in the front-rear direction is provided on the upper part.

  The tip of the blade 6 of the propeller wind turbine 5 is a curved portion 6A facing forward. Further, as shown in FIG. 1, the rear bottom surface of the body 1 </ b> A is a bottom slope 12 that rises up. An air guide hood 13 composed of a side plate 13B and an upper plate 13A is disposed from the air guide slope 2 at the top of the body 1A to the propeller wind turbine 5.

  The upper plate 13A is formed so that the front edge is located above the ceiling plate of the body 1A and covers the upper portion of the propeller wind turbine 5 portion, and the front portion is inclined upward than the rear portion. That is, as shown in FIG. 1, the upper surface is flat, but the lower surface has a thick front edge, is gradually formed thinner toward the rear edge, and the rear edge is curved upward. Accordingly, the airflow passing through the air guide hood 13 easily passes backward, and the airflow passing through the upper surface of the upper plate 13A suppresses the air guide hood 13 from rising.

The side plate 13B is inclined inward slightly toward the rear, the outer surface is flat on both the left and right sides, the inner surface is thicker at the front edge, and is gradually thinner toward the rear edge.
Although the air guide hood 13 is not always necessary, it is preferable to provide the air guide hood 13 because the rotation efficiency of the propeller wind turbine 5 can be improved. . Alternatively, it can be covered with a net to prevent danger or to prevent scattering due to breakage of the blade 6 of the propeller wind turbine 5.

  In this case, the airflow passing through the upper surface of the body 1A is faster than the airflow passing through the bottom surface of the body 1A, and the air density is reduced. The high-speed airflow along which the propeller windmill 5 hits. A motor 1B and a storage battery 1C are mounted below the air guide slope 2. A solar power generation panel (not shown) is stretched on the outer surface of the air guide hood 13.

  When the power generation vehicle 1 moves forward, the relative flow passes at a high speed in the backward direction along the upper and lower surfaces of the power generation vehicle 1. Since the thickness of the leading edge of the inner side surface is thicker, the airflow entering the air guide hood 13 becomes faster than the outer surface due to the Coanda effect and passes toward the propeller wind turbine 5 to increase the rotation efficiency.

  The airflow passing through the bottom lower surface of the body 1A rises along the bottom inclined surface 12 at the rear bottom of the body 1A, hits the front surface of the curved portion 6A of the blade 6 on the extended surface of the bottom inclined surface 12, and increases the rotation efficiency. .

  In this case, the airflow flowing along the air guide slope 2 hits the front surface of the curved portion 6A of the blade 6 of the propeller 5 on the extended line, and the propeller 5 is efficiently rotated.

  As shown in FIG. 2, the rear side surface of the body 1 </ b> A is an inclined side surface 1 </ b> D that is inclined inward, and an air guide path 1 </ b> E is formed between the inclined side surface 1 </ b> D and the side plate 13 </ b> B of the air guide hood 13. Thereby, the airflow flowing along the fast surface of the body 1A passes through the air guide path 1E at high speed and hits the propeller wind turbine 5 due to the Coanda effect, thereby increasing the rotation efficiency.

  As shown in FIG. 4, a main shaft 8 facing in the front-rear direction is laterally provided in a housing 7 facing in the front-rear direction fixed to the upper end of the column 4, and a power generation coil 9 is disposed around the main shaft 8. Yes. A rotating body 10 is rotatably mounted on the tip of the main shaft 8. Inside the rotating body 10, a magnet 11 is annularly arranged around the main shaft 8 so as to correspond to the power generating coil 9. As the rotating body 10 rotates, the magnetic force of the magnet 11 intermittently acts on the power generation coil 9 to generate power.

  The base end portion of the curved portion 6A facing forward of the plurality of blades 6 fixed to the outer peripheral surface of the rotating body 10 in the radial direction is the maximum chord length portion 6B. The curved portion 6A suppresses the diffusion of the airflow toward the distal end, and a large amount of airflow gathers in the maximum chord length portion 6B, whereby a rotational force is obtained and the rotation efficiency is increased.

  According to the power generation vehicle 1 configured in this manner, the propeller wind turbine 5 receives a high-speed air current even when traveling at a low speed, so that good power generation efficiency can be obtained. The generated electricity is stored in the storage battery 1C and rotates the motor 1B.

FIG. 5 is a side view of an essential part of the power generation vehicle showing the second embodiment. The same parts as those in the previous example are denoted by the same reference numerals, and description thereof is omitted.
In the second embodiment, as shown in FIGS. 5 and 6, an air volume adjusting door 15 is attached to the air guide slope 2 via a hinge 14 so as to be opened and closed.

  A worm wheel 16 is fixed to the base end portion of the air volume adjusting door 15, and a worm 18 rotated by a servo motor 17 is engaged with the worm wheel 16. However, this transmission system is not limited to this.

  As a result, when a high speed is generated during the running of the power generation vehicle 1, if the input is input to the servo motor 17 by a switch (not shown), the worm wheel 16 turns with the rotation of the worm 18, and the free end of the air volume adjusting door 15 rises To do.

  Therefore, since the airflow flowing from the upper surface of the body 1A to the air guide slope 2 rises in the direction indicated by the arrow X in FIG. 5, the air flow rate hitting the propeller windmill 5 is reduced and the propeller does not over-rotate.

  If necessary, a speedometer (not shown) for measuring the traveling speed of the power generation vehicle 1 is provided in the body 1A, and the servo motor 17 is driven by computer control based on the speed value to adjust the air volume. The opening and closing of the door 15 can be automatically adjusted.

  When the speedometer detects that the speed is below a certain speed, the free end of the flow rate adjusting door 15 is lowered under the control of the computer, and an air flow enters the air introduction hood 13. Rotates to generate electricity.

  FIG. 7 is a side view of a main part of the power generation vehicle 1 showing the third embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted. In the third embodiment, the propeller wind turbine 5 can be tilted together with the support 4.

  In FIG. 7, a base 44 is fixed on the rear upper surface of the frame 3. The support column 4 is erected on the base 44 via a support shaft 45 in the left-right direction so that it can tilt forward. A tilting means 46 is connected to the base end portion of the column 4. As the tilting means 46, for example, a fluid pressure cylinder is selected, but any rotary feed screw or any other means that can tilt the support column 4 may be used.

  A generator casing 7 is fixed forward on the upper end of the support column 4, and a rotating body 10 is rotatably mounted on the front of the casing 7. A plurality of blades 6 are mounted around the rotating body 10 so as to face the radial direction. The other overall structure is substantially the same as that shown in FIG. 4, and power is generated in the housing 7 as the blade 6 rotates.

When traveling at high speed, when the tilting means 46 is actuated by an input of a switch (not shown) and the support column 4 is tilted forward, the front surface of the blade 6 is close to the air guide slope 2, and thus the rotational speed decreases. .
Accordingly, the tilt angle of the propeller wind turbine 5 can be arbitrarily adjusted by the level of the traveling speed. This tilt can be automated using a speedometer and a computer.

FIG. 8 is a side view of a main part of the power generation vehicle showing the fourth embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted. In the fourth embodiment, a rail car is shown as the power generation vehicle 19.
In the power generation vehicle 19, a large inclined air guide slope 2 is formed from the front upper part to the rear lower part at the rear part of the body 19 </ b> A of the rail car traveling on the track.

At the rear part of the air guide slope 2, a support column 4 is erected on the upper part of the rear end of the frame 3, and the propeller windmill 5 is arranged on the upper part. Further, the rear surface of the bottom surface of the body 19A is a bottom slope 12 that rises rearward.
An air guide hood 13 is disposed at the rear of the body 19A so as to surround the propeller wind turbine 5.

  Thus, by disposing the propeller wind turbine 5 at the rear part of the rail car, the propeller wind turbine 5 can be made extremely large in diameter and can generate a large amount of power.

  As described above, according to the present invention, since the air guide slope 2 is formed at the rear portion of the power generation vehicle 1 and the propeller windmill 5 is disposed at the rear portion thereof, the diameter of the propeller windmill 5 can be increased. And it is small that the propeller becomes an obstacle when driving.

  In addition, since the Coanda effect due to the shape of the body can be used, the rotational efficiency can be increased, the power can be generated efficiently, and the electric power can be stored.
