Abstract

Disclosed is a power generation turbine capable of eliminating the loss of the power generation ratio due to an overflow to achieve highly efficient power generation and an improvement in the charging rate that goes therewith. The wind blowing through a main wind tunnel part (M) formed by a bulkhead (1) hits the wind receiving surface of blades (21 to 28) of a rotating blade (20) to rotate the rotating blade (20), while overflow's worth wind generated so as to wrap around the entry side of the bulkhead (1) wraps around the side of a sub wind tunnel part (S) of the bulkhead (1) as a result of the wind blowing from the front, and the overflow's worth wind wrapped around there is caught on the wind receiving surface of auxiliary blades (21a to 28a), resulting in the generation of force to further rotate the rotating blade (20) in the same direction. Accordingly, the overflow's worth wind flowing into the side of the sub wind tunnel part (S) does not become a loss, and conversely further acts on the rotation of the rotating blade (20).

Description

Power generation turbine

The present invention relates to a power generation turbine that, when used in an electric vehicle, for example, rotates a rotating blade using wind received in a traveling direction, generates power with a generator, and charges a battery.

In recent years, with the boom in environmental considerations (reduction of carbon dioxide gas emissions), electric vehicles equipped with motors in the drive trains and plug-in hybrid vehicles are attracting attention. When this type of vehicle is driven by a motor, it is equipped with a rechargeable battery (battery). The electric power stored there is used to rotate the motor and use it to drive the wheels.

The power source of such a car motor is electric power stored in the rechargeable battery. When the amount of storage decreases, for example, the charging power is supplied to the rechargeable battery at a home charging facility or battery charging station. It needs to be supplied and stored.

On the other hand, in the following Patent Document 1 and Patent Document 2, using the wind received in the traveling direction while the vehicle is running, the rotating blades of the power generation turbine are rotated, and the power is generated by the power generator of the turbine. There has been proposed a technique for charging and reducing the number of times of charging in the above-described facilities so as to extend the distance that can be traveled by one charge.

FIG. 3 is a schematic diagram schematically showing the mechanism of such a power generation turbine, which the inventor experimentally created for auxiliary charging for electric vehicles and plug-in hybrid vehicles. As shown in the figure, a wind tunnel 100 is installed in the traveling direction of the automobile, and turbine blades 20 are provided in the wind tunnel 100. A plurality of blades 21 to 28 that receive wind blowing through the wind tunnel 100 as the automobile travels are attached to the rotary blade 20. Therefore, wind blows into the wind tunnel 100 each time the automobile moves forward, and wind that tries to blow through the wind tunnel 100 is received by the wind receiving surfaces of the blades 21 to 28 to rotate the rotary blade 20. The rotating force is transmitted to the power generator 300 to generate power, and the rechargeable battery 400 is charged with the power.

However, in reality, when the wind is about to blow through the wind tunnel 100, a force for driving these components (a force for rotating the rotary blade 20 in the above direction, the rotation is transmitted to the generator 300). In contrast, a resistance is generated against the wind that tries to blow through the wind tunnel 100 due to the reaction of the force that is lost when the generator 300 is rotated, and the force that tries to rotate the generator 300 in a predetermined direction. As shown in FIG. 4, a part flows backward toward the wind tunnel 100 entering side, and a so-called overflow state occurs where the wind blows from the front on the wind tunnel 100 entering side and overflows to the outside of the wind tunnel 100. Pulled further by this overflowing wind, the overflow became more intense, causing the problem that power generation was not performed with the efficiency expected.

The present invention was devised in view of the above problems, and is intended to provide a power generation turbine capable of eliminating power generation efficiency loss due to overflow and capable of high-efficiency power generation and accompanying charge rate improvement. is there.

The configuration of the present invention is provided with a wind tunnel and rotating blades that receive and rotate the wind blown through the wind tunnel by one or more blades protruding from the wind tunnel. A power generation turbine that uses a rotation of a rotating blade to generate electric power and further charges a battery, wherein the wind flows in the wind tunnel from the installation position of the rotating blade toward the wind. A partition that divides the flow into two stages is provided to form a main wind tunnel portion where the blades of the rotary blade receive wind and a separate wind tunnel portion, and the blade tip position of any of the rotary blades is Install the rotating blade so that the blade tip position of the rotating blade is on the extension line of the partition when it is located closest to the wind tunnel, and the tip of each rotating blade is rotated at the tip of the blade. Protrudes from the wind receiving surface of the root of the blade through the septum extension to 従風Hora portion side to basically characterized by a structure in which an auxiliary blade for receiving the wind blowing through the driven wind tunnel portion side.

According to the above configuration, the wind that tries to blow through the main wind tunnel portion formed by the partition wall hits the blade of the rotating blade and turns the rotating blade, thereby generating the generator and charging the rechargeable battery. Do. On the other hand, as described above, an overflow occurs around the main wind tunnel portion so as to wrap around the entrance side of the partition wall on the outside of the partition wall. However, the wind blown from the front causes the wind for the overflow to flow to the side of the follower tunnel on the other side of the partition wall. Then, the wind that has flowed into the side of the follower wind tunnel is caught by the wind receiving surface of the auxiliary blade, and generates a force that further rotates the rotary blade in the same direction. Therefore, the overflow that flows into the side of the wind tunnel part is not lost, but on the contrary, it further acts on the rotation of the rotating blades, so that the power generation loss of the generator is eliminated and the power generation efficiency is improved. As a result, the charging rate also increases.

When the blade tip position of any of the rotary blades is located closest to the wind tunnel, the rotary blade is installed so that the blade tip position of the rotary blade is on the extension line of the partition wall. The blade of the blade rotates the rotating blade mainly by the wind received by the wind receiving surface of the blade so that the wind trying to blow through the main wind tunnel portion formed by the partition wall can be accurately caught without waste. This is to make it happen.

On the other hand, by providing the auxiliary blade on the outer peripheral side of the rotating circle (blade tip side) of the blade, the wind for the overflow that tries to blow through the side of the follower tunnel is received by the wind receiving surface of the auxiliary blade. The aim is to increase the rotational efficiency of the rotating blades. That is, as described above, in the conventional configuration, the overflow amount is lost as it is and does not act on the rotation of the rotating blades. However, in this configuration, the loss amount is reduced by the configuration as described above. So that it can act on the rotation. That is, in the conventional configuration, the overflow portion is lost as it is and does not act on the rotation of the rotating blades. However, in this configuration, the overflow portion is provided with a partition wall as described above and the follower wind tunnel portion. The side is blown through and caught by the wind receiving surface of the auxiliary blade so as to be able to act on the rotation of the rotary blade, and the rotation efficiency of the rotary blade is improved without losing that amount.

As shown in Example 2 to be described later, at least the entrance side of the wind tunnel widens in a divergent shape as it goes to the windward side, the entrance side wind tunnel opening area is wide, and the entrance area becomes narrower as it enters the inside. Therefore, just near the surface receiving the wind of the rotary blades, that is, the blades and the auxiliary blades, the wind speed is higher than that of the entrance side, so that a stronger wind blows through. Accordingly, the wind receiving surfaces of the blade and the auxiliary blade on the wind tunnel side of that portion receive a stronger wind, which further improves the rotation efficiency of the rotating blades. More specifically, the wind tunnel may be configured in a diffuser shape.

Further, even if at least the entrance side of the wind tunnel spreads toward the windward side, the end spread portion on the wind tunnel entrance side is divided by the partition as shown in FIG. And the side of the wind tunnel portion are asymmetric in cross section in the drawing, and the spread H1 on the entrance side of the wind tunnel portion separated by the partition wall is larger than the spread H2 on the entrance side of the main wind tunnel portion (H1> H2), In addition, in the narrowed part of the inner periphery of the wind tunnel, the space h1 on the side of the follower wind tunnel part separated by the partition wall near the rotary blades is smaller than the space h2 on the rotary blade blade side of the main wind tunnel part receiving the wind (h1). <H2) is configured as follows. That is, on the wind tunnel entrance side, the speed of the wind flow on the side of the follower wind tunnel and the speed of the flow on the side of the main wind tunnel are the same. However, since the spread H1 on the entrance side of the follower wind tunnel is originally wider than the spread H2 of the main wind tunnel, a larger amount of wind can be collected. In the inner peripheral portion of the constricted position of the near wind tunnel, the space h1 on the side of the follower wind tunnel portion is in a state (h1 <h2) narrower than the space h2 on the side of the main wind tunnel portion. The flow velocity of the wind that blows through the space on the side of the secondary wind tunnel is larger than the flow velocity of the wind that blows through the space on the side of the main wind tunnel, so that the force that tries to rotate the rotating blades by receiving the wind at the wind receiving surface of the auxiliary blade. It will act even more strongly. However, the auxiliary blade is only an auxiliary of the blade, and the size and shape of the wind receiving surface and the shape of the wind receiving surface are not the appropriate size and shape as the original blade on the basis, so each auxiliary blade The wind force received by the wind receiving surface of each blade is substantially equal to or slightly less than the wind force received by the wind receiving surface of each blade.

Therefore, as described above, the wind for the overflow that would normally be lost is blown through the side of the follower wind tunnel by providing the partition as described above, and is caught by the wind receiving surface of the auxiliary blade, so that the rotating blade In addition to acting on the rotation of the auxiliary blade, the above-described space configuration (H1> H2, h1 <h2) allows the rotating blades to rotate by receiving the wind on the wind receiving surface of the auxiliary blade. As a result of the force acting more strongly, the improvement in the rotation rate of the rotary blade is further enhanced.

According to the configuration of the present invention as described above, the wind that tries to blow through the main wind tunnel portion formed by the partition wall hits the blades of the rotating blades and turns the rotating blades, thereby generating the generator. In addition to charging the rechargeable battery, the overflow generated so as to go around the entrance side of the partition wall flows into the side of the follower tunnel on the other side of the partition wall by the wind blowing from the front, and the auxiliary blade Since the wind is caught by the wind receiving surface, it will generate a force to further rotate the rotating blade in the same direction, so the overflow flowing into the side of the follower tunnel will rotate through the auxiliary blade, without loss. Excellent effect that the power generation efficiency of the generator will be improved and the charging rate will be increased accordingly. It will be achieved.

Further, if at least the entrance side of the wind tunnel widens toward the windward side, the opening area on the entrance side is wide, and the opening area becomes narrower as it enters the inside. In the vicinity of the surface receiving the wind of the auxiliary blade, the wind speed is higher than the entrance side, so that a strong wind blows through, and the wind receiving surface of the blade and the auxiliary blade on the wind tunnel side of that part is stronger by that amount. Since the wind is received, the rotational efficiency of the rotary blade is further increased.

In addition, at least the entrance side of the wind tunnel is configured to spread in a divergent shape as it goes to the windward side, and the divergent part of the wind tunnel entry side is divided between the main wind tunnel part side and the follower wind tunnel part side divided by the partition wall, The cross-sectional asymmetry in the drawing is such that the width H1 of the inlet side of the wind tunnel portion separated by the partition wall is larger than the width H2 of the inlet side of the main wind tunnel portion (H1> H2). In the peripheral surface portion, the space h1 on the side of the follower wind tunnel portion separated by the partition wall near the rotor blade is configured to be narrower (h1 <h2) than the space h2 on the rotor blade blade side of the main wind tunnel portion receiving the wind. In this case, the above-mentioned configuration is such that the wind of the overflow that has been lost in the past is caught by the wind receiving surface of the auxiliary blade and acts on the rotation of the rotating blade, thereby improving the rotation efficiency of the rotating blade. In addition to the effect, the structure of the above space (H1> H2, h1 <h2) results in that the force of receiving the wind on the wind receiving surface of the auxiliary blade and turning the rotating blade acts more strongly. Thus, an even higher effect can be expected in that the rotation rate of the rotating blades can be further improved.

It is the structure schematic which showed typically the structure around the electric power generation of the power generation turbine which concerns on this invention. It is the structure schematic which showed typically the structure around the electric power generation of the power generation turbine which concerns on 2nd Example of this invention. It is the schematic which represented typically the mechanism of the conventional power generation turbine which this inventor created experimentally for the auxiliary | assistant charge for electric vehicles or plug-in hybrid vehicles. In the configuration shown in FIG. 3, a reverse flow is generated toward the wind tunnel 100 entering side due to the resistance generated when the rotary blade 20 or the like is rotated, and the wind tunnel 100 is blown from the front on the wind tunnel 100 entering side. It is explanatory drawing explaining the reason which will be in the so-called overflow state which overflows outside.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a schematic configuration diagram schematically showing a configuration around power generation of a power generation turbine according to the present invention mounted on an electric vehicle.

As shown in the figure, the present power generation turbine has a wind tunnel 100 installed along the traveling direction of the electric vehicle (the right side of the drawing is the forward direction of the vehicle), and goes directly to the wind blowing through the wind tunnel 100. It has a shaft 200 in the direction and is installed in a state where the shaft 200 is shifted to the side of the wind-through direction, and the surfaces of the blades 21 to 28 that receive the wind are shaped so as to be recessed in cross section with respect to the wind-through direction. The blades 21 to 28, which are present on the side of the wind tunnel 100 and have a concave cross section, are provided with rotating blades 20 that rotate by receiving the wind blowing through the wind tunnel 100. A power generator 300 that generates power using force is provided via the shaft 200 of the rotary blade 20 and the belt 300a, and further a charger that stores the electricity generated and output by the power generator 300. It has a 00.

Since the shaft 200 is installed at a position lowered on the rotary blade 20 in the drawing, the wind tunnel 100 has a semicircular cross section on the drawing in order to secure the rotation allowance of the rotary blade 20. It has a shape protruding downward.

In this configuration, a partition wall 1 that divides the flow into two stages along the wind flow is provided in the wind tunnel 100 on the wind entrance side from the installation position of the rotary blade 20. The blades 21 to 28 form a main wind tunnel portion M that receives wind and a separate wind tunnel portion S. At the same time, when the tip position of any of the blades 21 to 28 of the rotary blade 20 is located closest to the wind tunnel 100, the rotation tip 20 of the rotary blade 20 rotates so that the blade tip position exists on the extension line of the partition wall 1. The blade 20 is installed. Further, at the tip of the blades 21 to 28 of each rotary blade 20, the tip protrudes from the wind receiving surface of the blades 21 to 28 of the rotary blade 20 to the side of the wind tunnel portion S via the partition 1 extension line. Auxiliary blades 21a to 28a for receiving wind blowing through the side are provided.

According to the configuration of the above embodiment, the wind that tries to blow through the main wind tunnel portion M formed by the partition wall 1 hits the blades 21 to 28 of the rotary blade 20 and rotates the rotary blade 20, thereby generating power. The battery 300 is generated and the rechargeable battery 400 is charged. On the other hand, as described above, overflow occurs around the main wind tunnel portion M so as to go around the entrance side of the partition wall 1 on the outer side of the partition wall 1. However, the wind blown from the front causes the wind for the overflow to flow toward the side of the follower tunnel S on the other side of the partition wall 1. Then, the wind that has flowed to the side of the follower wind tunnel portion S is caught by the wind receiving surfaces of the auxiliary blades 21a to 28a, and generates a force for further rotating the rotary blade 20 in the same direction. Accordingly, the overflow flowing into the side of the wind tunnel portion S is not lost, but on the contrary, it further acts on the rotation of the rotary blade 20, so that the power generation loss of the power generator 300 is eliminated correspondingly and the power generation efficiency is improved. As a result, the charging rate to the charger 400 increases accordingly.

When the tip of any blade 21 to 28 of the rotary blade 20 is located closest to the wind tunnel 100, the rotary blade 20 is installed so that the blade tip position of the rotary blade 20 is on the extension line of the partition wall 1. The reason is that the blades 21 to 28 of the rotary blade 20 can accurately catch the wind that tries to blow through the main wind tunnel portion M formed by the partition wall 1 without waste. This is because the rotary blades 20 are mainly rotated by the wind received by the wind receiving surface.

On the other hand, by providing the auxiliary blades 21a to 28a on the outer peripheral side of the rotating circle (blade 21 to 28 tip side) of the blades 21 to 28, the overflow wind that tries to blow through the side of the follower tunnel portion S is obtained. The aim is to increase the rotational efficiency of the rotary blade 20 by receiving it on the wind receiving surfaces of the auxiliary blades 21a to 28a. That is, as described above, in the conventional configuration, the overflow amount is lost as it is and does not act on the rotation of the rotary blade 20. However, in this configuration, the loss amount is rotated by the above configuration. The blade 20 can be rotated. That is, in the conventional configuration, the overflow amount is lost as it is and does not act on the rotation of the rotary blade 20. However, in this configuration, such an overflow portion is provided with the partition wall 1 as described above. The wind tunnel portion S side is blown through and is caught by the wind receiving surfaces of the auxiliary blades 21a to 28a so as to be able to act on the rotation of the rotary blades 20. Rotational efficiency is improved.

As described above, in this configuration, the wind that tries to blow through the main wind tunnel portion M formed by the partition wall 1 hits the blades 21 to 28 of the rotary blade 20 and rotates the rotary blade 20, thereby generating the generator. In addition to generating power 300 and charging the rechargeable battery 400, the overflow generated around the entrance side of the partition wall 1 is blown from the front by the wind blown from the front side of the follower tunnel on the other side of the partition wall 1. Since the air flows around the portion S and is caught by the wind receiving surfaces of the auxiliary blades 21a to 28a and generates a force for further rotating the rotary blade 20 in the same direction, the overflow portion flowing into the follower wind tunnel portion S side is generated. On the contrary, the rotation of the rotary blade 20 is further acted through the auxiliary blades 21a to 28a without loss, and the power generation of the power generator 300 is performed. It will be of improving the rate, along with it, so that an excellent effect that the charging rate of the rechargeable battery 400 is also high.

FIG. 2 is a schematic configuration diagram schematically showing the configuration around the power generation of the power generation turbine according to the second embodiment of the present invention, which is also mounted on the electric vehicle.

In the configuration of the present embodiment, the configuration of the wind tunnel 100 is different from that of the configuration shown in the first embodiment, and the other configuration is the same as that of the present embodiment, so that detailed description thereof will be omitted. (The same configuration has the same number).

In the configuration of the present embodiment, at least the entrance side of the wind tunnel 100 is configured to spread in a divergent shape as it goes to the windward side in the normal traveling direction of the automobile.

With such a configuration, the opening area of the wind tunnel on the entry side is large, and the opening area becomes narrower as it enters the inside, so that it receives the wind of the rotary blades 20, that is, the blades 21 to 28 and the auxiliary blades 21a to 28a. In the vicinity of the surface, the wind speed is higher than that of the entrance side, and the stronger wind blows through. Accordingly, the wind receiving surfaces of the blades 21 to 28 and the auxiliary blades 21a to 28a on the wind tunnel 100 side in the vicinity thereof receive a stronger wind, thereby further improving the rotation efficiency of the rotary blade 20. In the configuration of this embodiment, the wind tunnel 100 is configured in a diffuser shape as illustrated.

Further, in the configuration of the present embodiment, the divergent portion on the side where the wind tunnel 100 enters is asymmetric in cross section in the drawing between the main wind tunnel portion M side and the follower wind tunnel portion S side separated by the partition wall 1. The entrance H1 of the separated wind tunnel portion S is larger than the entrance H2 of the main wind tunnel portion M (H1> H2), and conversely, in the narrowed portion of the inner periphery of the wind tunnel 100, The space h1 on the side of the follower wind tunnel portion S separated by the partition wall 1 near the rotary blade 20 is configured to be narrower (h1 <h2) than the space h2 on the rotary blade blades 21 to 28 side of the main wind tunnel portion M receiving the wind. ing.

Because of such a configuration, first, on the entrance side of the wind tunnel 100, the speed of the wind flow on the side of the follower wind tunnel section S and the speed of the flow on the side of the main wind tunnel section M are the same. However, since the spread H1 on the entrance side of the follower wind tunnel portion S is wider (larger) than the spread H2 of the main wind tunnel portion M (H1> H2), a larger amount of wind can be collected. As the air enters the inside, the space h1 on the side of the wind tunnel portion S is narrower than the space h2 on the side of the main wind tunnel portion M (h1 <h2) in the inner peripheral portion of the constricted position of the wind tunnel 100 close to the position where the rotary blade 20 is installed. On the other hand, the flow velocity of the wind that blows through the space on the side of the wind tunnel portion S including the overflow is larger than the flow velocity of the wind that blows through the space on the main wind tunnel portion M side. The force of receiving the wind at the wind receiving surface 28a and turning the rotary blade 20 acts more strongly. However, the auxiliary blades 21a to 28a are only auxiliary to the blades 21 to 28, and the size and shape of the surface receiving the wind and the shape of the wind receiving surface are appropriate sizes and shapes like the original blades 21 to 28 on the basis thereof. Therefore, the wind force received by the wind receiving surfaces of the auxiliary blades 21a to 28a is almost equal to or slightly less than the wind force received by the wind receiving surfaces of the blades 21 to 28. Yes.

Therefore, as described above, the wind for the overflow that would normally be lost is blown through the side of the follower tunnel S by providing the partition wall 1 as described above, and is caught by the wind receiving surfaces of the auxiliary blades 21a to 28a. In addition to acting on the rotation of the rotary blade 20, the above-described space configuration (H 1> H 2, h 1 <h 2) allows the wind to flow on the wind receiving surfaces of the auxiliary blades 21 a to 28 a. As a result, the force to receive and rotate the rotary blade 20 acts more strongly, and as a result, the improvement of the rotation rate of the rotary blade 20 is further enhanced.

As described above in detail, in the configuration of the present embodiment, since at least the entrance side of the wind tunnel 100 is configured to spread in a divergent shape as it goes to the windward side along the original traveling direction of the vehicle, the entrance opening area is wide. As the air enters the inside, the opening area is narrowed, so that just near the surface receiving the wind of the rotary blade 20, that is, the blades 21 to 28 and the auxiliary blades 21a to 28a, the wind speed is higher than that of the entrance side. The strong wind blows through, and the wind receiving surfaces of the blades 21 to 28 and the auxiliary blades 21a to 28a on the wind tunnel 100 side of the portion receive the strong wind accordingly. Therefore, the rotational efficiency of the rotary blade 20 is further increased.

In addition, at least the entrance side of the wind tunnel 100 is configured to expand in a divergent shape as it goes to the windward side, and the end spread portion on the wind tunnel 100 entry side is separated from the main wind tunnel portion M side and the follower wind tunnel portion separated by the partition wall 1. On the S side, the cross-sectional asymmetry in FIG. 2 is greater, and the spread H1 on the entrance side of the follower tunnel portion S separated by the partition wall 1 is larger than the spread H2 on the entry side of the main wind tunnel portion M (H1> H2). On the other hand, in the narrowed inner peripheral surface portion of the wind tunnel 100, the space h1 on the side of the follower wind tunnel portion S separated by the partition wall 1 near the rotary blade 20 has the rotary blade blades 21 to 28 of the main wind tunnel portion M receiving the wind. Since it is configured to be narrower than the space h2 on the side (h1 <h2), the wind of the overflow that has been conventionally lost is caught by the wind receiving surfaces of the auxiliary blades 21a to 28a, and the rotating blade 2 In addition to the effect of the above-described configuration in which the rotation efficiency of the rotary blade 20 is improved, the configuration of the space (H1> H2, h1 <h2) allows the auxiliary blades 21a to 28a to As a result of the force acting on the wind receiving surface receiving the wind to rotate the rotating blades 20 acting more strongly, it is possible to further increase the rotation rate of the rotating blades 20, further increasing the effect. Improvement is expected.

The power generation turbine according to the present invention is not limited to the one used for charging the electric vehicle shown in the above-described illustrated example, and various modifications can be made without departing from the gist of the present invention. Of course.

The power generation turbine of the present invention can be used for other purposes as long as it can generate power using wind, for example, it can be used for power generation facilities as well as for electric vehicles and plug-in hybrid vehicles. Needless to say.
