Description

[Technical Field]

[0001] The present invention relates to a wind speed accelerating wind turbine mounted on a moving body, which is mounted on an automobile, railroad vehicle, ship, or other moving body to increase the wind speed at the rear of the wind turbine and at the outlet of the wind tunnel, improve the rotation efficiency of the wind turbine blades, increase the amount of power generation, and supply or assist the moving body with power, while improving the installation height and installation and support stability. [Background technology]

[0002] In recent years, with the increasing demand for the prevention of global warming, the development of new clean energy sources has become an urgent issue. One such clean energy source that has attracted attention is the wind power generation system, which does not emit CO2.

[0003] However, although wind power is currently under development, its status as an alternative to oil is low because no effective means of capturing wind energy has been developed.

[0004] Up until now, wind power generation using lifting propeller wind turbines has been the mainstream method of supplementing wind energy. However, lifting propeller wind turbines require long blades (propeller blades), which creates the problem of the wind turbine itself becoming large.

[0005] The current energy efficiency is around 40%, meaning that it captures around 40% of the wind energy. The theoretical maximum efficiency is 59.3% (Betz's Law).

[0006] Sometimes, when people pass through the gaps between buildings or through arcades, they encounter unexpected strong winds. This is because the wind, blocked by the walls of buildings, seeks an opening and concentrates at a passable point in the gap or arcade.

[0007] This is considered to be a type of Laval tube effect. Therefore, a wind power generation device has been proposed in which the wind turbine is placed in the center of a Laval tube, which is made by connecting two trumpet tubes at the front and rear, i.e., near the smallest cross-sectional area (Patent Document 1).

[0008] The inventors installed a partition between the electric fan and the wind turbine, drilled a hole in the wall, and used the electric fan to blow air through the hole. They then placed the wind turbine directly behind the hole and investigated the rotation speed of the wind turbine. To their surprise, they found that the rotation speed of the wind turbine was much lower than when the fan was used to blow air directly to the wind turbine without a partition.

[0009] In other words, it was discovered that not only the wind hitting the front of the wind turbine but also the amount of wind passing from the periphery to the rear of the wind turbine is important for the rotation of the wind turbine, and a wind-concentrating type wind turbine was proposed that increases the amount of power generated by the wind turbine by drawing in the wind behind the wind turbine with the large amount of wind power concentrated by the outer wind tunnel body of the double-structure wind turbine (Patent Document 2).

[0010] The wind-collecting wind turbine described above functions on the following principle. If the velocity of the air passing through the turbine is V, its density is ρ, and its pressure is P, then the total energy of the wind per unit volume is (1 / 2)ρV. 2 Since +P = constant, gathering wind reduces pressure energy and increases kinetic energy. This is the rectification of V and P (the opposite of randomization), so entropy (S) decreases. Therefore, free energy increases by -TΔS (T: temperature).

[0011] Therefore, the wind-collecting type has more energy. However, this is based on the assumption of a steady flow in a Bernoulli flow tube. If a wind turbine is placed on this and energy is extracted, V behind the turbine will decrease and P will increase.

[0012] Therefore, to make this flow closer to a steady flow, it is necessary to speed up the slow flow by using the friction of the high-speed flow outside the flow tube. In other words, the high-speed air molecules push the slowed-down air molecules behind the wind turbine backward (Patent Document 3).

[0013] In order to knock out the air molecules behind the wind turbine, it is effective to provide gaps on both sides of the wind turbine installed inside the intermediate wind tunnel body, or on both sides of the sides and the top and bottom, through which the wind can blow through, and to allow a high-speed wind to flow (Patent Document 4).

[0014] Furthermore, the movement towards a carbon-neutral and hydrogen-based society is currently accelerating around the world, making the use of renewable energy essential. For example, developments are underway to equip automobiles and other mobile vehicles with wind turbines or solar power generators to supply or supplement power, and to use rigid wing sails on ships for propulsion (Patent Documents 5, 6, and 7).

[0015] In the case of wind power generation, output is proportional to the cube of the wind speed, so wind collectors like the ones mentioned above are used to accelerate the wind speed. That is, in the natural environment, the average annual wind speed is about 3 to 5 m / s, and since the capacity (rated output) of the wind power generator is not fully utilized, wind collectors are used to accelerate the wind speed.

[0016] The speeds of the moving objects are 20km / h (5.6m / s), 40km / h (11.1m / s), 60km / h (16.7m / s), 80km / h (22.2m / s), and 100km / h (27.8m / s), which results in extremely fast wind speeds that are extremely advantageous for wind power generation. Furthermore, if a wind collector is attached, even greater amounts of power can be generated.

[0017] It is necessary to make the wind collecting device as compact as possible so as not to create resistance when the moving object is moving. [Prior art documents] [Patent documents]

[0018] [Patent Document 1] Special Publication No. 2008-520900 [Patent Document 2] Japanese Patent Application Laid-Open No. 2011-140887 [Patent Document 3] Patent No. 6033870 [Patent Document 4] Patent No. 6110455 [Patent Document 5] Japanese Patent Application Laid-Open No. 2011-032936 [Patent Document 6] Japanese Patent Application Laid-Open No. 2009-191835 [Patent Document 7] Japanese Patent Application Laid-Open No. 2005-291193 Summary of the Invention [Problem to be solved by the invention]

[0019] The present invention is based on the basic ideas of the above-mentioned Patent Documents 3 and 4. The details thereof will be explained below.

[0020] When people pass through the gaps between buildings or through arcades, they often encounter unexpected strong winds. As mentioned above, this is because the wind that is blocked by the walls of buildings seeks gaps and concentrates at passable points in the gaps or arcades.

[0021] If the density of the passing air is ρ and the wind speed is V, the wind energy per unit volume is (1 / 2)ρV 2 Since +P = constant, when the air is blocked by a wall and the velocity becomes 0, the only energy is pressure, and walls of high-pressure air are created on both sides of the entrance to the valley, etc. This forms a wind tunnel duct, and it is thought that the wind speed increases.

[0022] Therefore, as shown in Figures 21(a) and (b), a fan 11 (φ=240 mm) and a wind turbine 12 (φ150 mm) were placed at a distance of approximately 750 mm, and brim-shaped wall members 13a and 13b were provided on the outside of the rim of the wind inlet of the wind turbine 12, respectively, and the rotation speed of the wind turbine 12 when air was blown from the fan 11 was observed.

[0023] The outer diameter of wall member 13a was configured to be larger than the wind flux of fan 11, and the outer diameter of wall member 13b was configured to be equal to or smaller than the wind flux of fan 11. Although not shown, the rotation speed was also observed in the same manner when no wall member was provided.

[0024] As a result, when wall member 13a was provided (Fig. 21(a)), the rotation speed of wind turbine 12 was significantly lower than when no wall member was provided. This is because, since the wind source is an electric fan, basically only a wind flux equivalent to the diameter of the blades of fan 11 can be obtained, and therefore, if the outer diameter of the wall member is made larger than the wind speed of fan 11, the wind flow to the back of wind turbine 12 is completely blocked.

[0025] Furthermore, when wall member 13b was provided (Fig. 21(b)), the rotation speed of the wind turbine increased compared to when wall member 13a was provided. This is thought to be because when wall member 13b, which has an outer diameter equal to or smaller than the wind flux of fan 11, is provided, part of the wind volume flows behind the wind turbine, pulling the wind passing through wind turbine 12 and increasing its speed.

[0026] When wind passes through a wind turbine, energy is lost and the wind speed decreases. In terms of molecular kinetic theory, this means that the temperature decreases. The above experiment shows that the decreasing energy of the wind flow behind the wind turbine is compensated for by mixing and friction with the airflow on the outside, which has a higher wind speed, i.e., greater dynamic pressure and kinetic energy, and the speed of the wind flow behind the wind turbine increases.

[0027] As a result, it is clear that in order to increase the rotation speed of a wind turbine, it is important to force the wind passing through the wind turbine out the rear of the turbine.

[0028] In light of the above circumstances, the present invention aims to solve the problems of the prior art and to provide a wind speed accelerating wind turbine mounted on a moving body that is mounted on a moving body, increases the wind speed at the rear of the wind turbine and at the outlet of the wind tunnel, improves the rotational efficiency of the wind turbine, increases the amount of power generated, and supplements the power source of the moving body by improving the installation height and the stability of installation and support. [Means for solving the problem]

[0029] The mobile body mounted wind speed accelerating wind turbine of the present invention that achieves the above-mentioned object is a mobile body mounted wind speed accelerating wind turbine that is mounted on a mobile body, and is characterized by comprising a wind tunnel body and a wind turbine, the wind tunnel body having a generally rectangular cross section: a front wind tunnel body whose cross section area is reduced linearly or curved from the wind inlet or is kept constant; a rear wind tunnel body having a generally rectangular cross section that is increased linearly or curved from the position of the reduced cross section to the wind outlet or keeps the same cross section; a wind guide plate is formed at the wind inlet; the wind turbine is installed at the reduced part of the wind tunnel body with the distance from the long side of the wind tunnel body minimized; and the wind inlet is positioned facing the running wind (claim 1).

[0030] The term "approximately rectangular cross section" includes oval shapes with long and short sides, and other polygonal shapes. By making the wind tunnel body approximately rectangular in cross section, the present invention makes it possible to supply the wind flowing beside the wind turbine to the spaces on both sides of the turbine without letting it escape above and below the turbine, effectively knocking out the airflow whose speed has decreased at the rear of the turbine and recovering the velocity energy of the airflow at the rear of the turbine, compared to a wind tunnel body with a circular or square shape.

[0031] In this invention, when wind is received through the wind inlet, it passes through the front wind tunnel body and reaches the wind turbine installed in the reduced section with a roughly rectangular cross section, causing the wind turbine to rotate. At the same time, high-speed airflows blow through from the spaces on both sides of the wind turbine. The airflow behind the wind turbine, which has lost energy due to the wind turbine, is knocked out by the high-speed airflows blowing through from the spaces on both sides, restoring the velocity energy of the airflow behind the wind turbine.

[0032] As a result, the cross-sectional area of ​​the front wind tunnel body, which is formed so that it decreases linearly or curvedly or has the same area from the wind inlet to the position where the wind turbine is installed, increases the speed of the wind and leads it to the wind turbine, and the amount and speed of the wind passing through the wind turbine are increased and supplied to the rear wind tunnel body.

[0033] The rear wind tunnel has an open wind outlet that expands linearly or curvedly from the position of the reduced cross-sectional area, or is formed to maintain the same cross-sectional area. The wind supplied to the rear wind tunnel is brought into contact with a faster, lower-pressure airflow blowing outside the rear wind tunnel, and the slower-speed, higher-pressure wind in the rear wind tunnel is drawn out of the wind outlet by mixing, friction, and absorption, thereby again increasing the amount and speed of the wind passing through the wind turbine.

[0034] That is, the present invention increases the wind speed at the rear of the wind turbine by accelerating the wind speed in two stages, thereby improving the rotational efficiency of the wind turbine and increasing the amount of power generation.

[0035] The configuration, operation, and effects of the present invention are the same whether the wind tunnel is placed horizontally or vertically. Therefore, when the wind tunnel is attached to a moving object, the height of the device and the stability of installation and support are improved.

[0036] One embodiment of the present invention is characterized in that at least two or more of the above-mentioned moving body mounted wind speed accelerating wind turbines are arranged (claim 2).

[0037] When a large amount of power generation is required, a large number of wind speed acceleration wind turbines of the present invention are arranged. As a result, compared to when a large number of wind speed acceleration wind turbines are arranged closely together, the wind blows around each wind speed acceleration wind turbine, improving the wind collection effect.

[0038] At the same time, the surrounding running wind draws the slower, higher pressure wind behind the wind turbine out through the wind outlet, increasing the volume and speed of the wind passing through the wind turbine and increasing the amount of power generation.

[0039] One embodiment of the present invention is a moving body mounted wind speed accelerating wind turbine that is mounted on a moving body, and is composed of a wind tunnel body and a wind turbine. The wind tunnel body comprises a front wind tunnel body that is approximately rectangular in cross section and whose cross section area is reduced linearly or curved from the wind inlet or is formed to remain the same, and a rear wind tunnel body that is approximately rectangular in cross section and is formed so that the cross section area is increased linearly or curved from the position of the reduced cross section to the wind outlet or is formed to maintain the same cross section, and the wind turbine is installed in the reduced section of the approximately rectangular cross section with spaces formed on both sides, and the wind inlet is arranged facing the direction of travel (claim 3).

[0040] According to the present invention, the same functions and effects as those of the invention set forth in claim 1 are achieved. When the device is mounted on a moving body, the problem of height of the device and the stability of installation and support are improved.

[0041] One embodiment of the present invention is characterized in that at least two or more of the wind tunnel bodies are arranged (claim 4).

[0042] According to the present invention, the same functions and effects as those of the invention described in claim 3 are obtained. [Effects of the Invention]

[0043] According to the present invention, it is possible to provide a wind speed accelerating wind turbine mounted on a moving body that increases the wind speed at the rear of the wind turbine and at the outlet of the wind tunnel body, improves the rotational efficiency of the wind turbine blades, increases the amount of power generation, and also provides improvements to the height of the device and the stability of installation and support, thereby supplying or supplementing power to a moving body.

[0045] An embodiment of the present invention will be described below with reference to the drawings.

[0046] Fig. 1 is a schematic cross-sectional view of a moving body mounted wind speed accelerating wind turbine F1 of the present invention, and Fig. 2 is a cross-sectional view taken along line XX in Fig. 1. In the figure, 21 is a wind turbine, 22d is a contraction section, and 22 is a wind tunnel body. The wind tunnel body 22 is made up of a front wind tunnel body 22-1 and a rear wind tunnel body 22-2. Or rather.

[0047] The front wind tunnel body 22-1 has a generally rectangular cross section, and an air inlet 22a is formed on the side of the wind guide plate G. The air inlet 22a is formed to have a cross-sectional area that is linearly or curvedly reduced or the same as the air inlet 22a. The air inlet 22a is opened widely to receive a large amount of wind generated by running.

[0048] The front wind tunnel body 22-1 may have a substantially rectangular cross section, an air inlet 22a formed on the side of the wind guide plate G, and may be formed with the same cross-sectional area as the air inlet 22a.

[0049] The rear wind tunnel body 22-2 has a generally rectangular cross section and has an open wind outlet 22b that expands linearly or curvedly from the position of the reduced cross section or is formed to maintain the same cross section. In the figure, S denotes spaces formed on both sides of the wind turbine 21, and 10 denotes a generator.

[0050] The generally rectangular cross section includes an ellipse having long and short sides, other polygons, etc. In Fig. 2, 23 is the long side and 24 is the short side.

[0051] The wind turbine 21 has a space S on both sides and a reduced section 22 having a substantially rectangular cross section. d, the distance between the wind turbine 21 and the long side 23 of the wind tunnel body 22 is set to a minimum.

[0052] The ratio of the short side portion 24 to the long side portion 23 of the wind tunnel body 21 is set to 1 to 10 times.

[0053] This allows the high-speed airflow that blows through the spaces on both sides of the wind turbine and the low-speed, high-pressure airflow that has been diffused by the rear wind tunnel body to be accelerated by friction with the high-speed airflow outside the wind tunnel body, thereby knocking out the slowed-down airflow at the rear of the wind turbine that has lost its energy due to the wind turbine, effectively recovering the velocity energy of the airflow at the rear of the wind turbine and improving the rotational efficiency of the blades.

[0054] In the above ratio of 1 to 10, if the ratio exceeds 10, the increase in the perimeter / area ratio relative to the area does not increase significantly, and if the ratio exceeds 10, the device becomes too large.

[0055] In each of the above configurations, when the wind inlet 22a receives the traveling wind (arrow W), the traveling wind W is guided by the wind guide plate G and supplied to the wind turbine 21 in the contracting section 22d of the front wind tunnel body 22-1. At the same time, high-speed airflow blows through the spaces S formed on both sides of the wind turbine 21.

[0056] Then, the high-speed airflow (arrow A) blowing through the space S on both sides of the wind turbine 21 knocks out the airflow, whose speed has decreased at the rear of the wind turbine 21 after energy has been taken away by the wind turbine 21, to the rear wind tunnel body 22-2, thereby recovering the speed energy of the airflow at the rear of the wind turbine 21 and improving the rotational efficiency of the wind turbine 21.

[0057] Next, the airflow supplied to the rear wind tunnel body 22-2 comes into contact with the faster, lower-pressure airflow (arrow B) blowing outside the rear wind tunnel body 22-2, and through mixing, friction, and absorption, the slower-speed, higher-pressure air inside the rear wind tunnel body is drawn out through the wind outlet 22b, once again increasing the volume and speed of the air passing through the wind turbine 21. In other words, the present invention increases the wind speed at the rear of the wind turbine 21 by accelerating the wind speed in two stages, improving the rotational efficiency of the wind turbine 21 and increasing the amount of power generation.

[0058] FIG. 3 is a schematic plan view of the wind speed acceleration wind turbine F1 having the above-described configuration, mounted (placed) horizontally on a moving vehicle C with the wind inlet 22a facing the traveling wind, and FIG. 4 is a schematic front view of the same.

[0059] In the figure, the air inlet 22a is directly fixed to the top of the driver's seat, facing the direction of travel of the automobile C. However, it may also be fixed by providing an appropriate mounting device.

[0060] As a result, as the automobile C moves, the wind generated by the movement of the automobile C reaches the inside of the front wind tunnel body 22-1 of the wind tunnel body 22 through the wind inlet 22a, and at the same time, the high-speed airflow (arrow A) blowing through the space S on both sides of the wind turbine 21 and the airflow (arrow B) blowing outside the rear wind tunnel body 22-2 are added to the wind turbine 21, causing it to rotate and generating electricity with the generator 10.

[0061] Fig. 5 is a schematic side view of the wind speed acceleration wind turbine F1 having the above-described configuration, mounted (placed) horizontally on a moving railway vehicle T with the wind inlet 22a facing in the direction of travel of the railway vehicle T. When mounted, it is configured so as not to interfere with the overhead wires. The wind speed acceleration wind turbine F1 may also be mounted on cargo.

[0072] FIG. 17(a) is a front view and (b) is a cross-sectional view of a simplified wind collecting device, and the cross-sectional area of ​​the wind tunnel body 22 is not changed.

[0073] FIG. 18 shows an embodiment in which the wind speed acceleration type wind turbine F2 having the above-mentioned configuration is supported by a support 11. In this embodiment, a high-speed air current also blows through the space S below the wind turbine 21, improving the rotation efficiency of the wind turbine and increasing the amount of electricity.

[0074] In each of the illustrated embodiments, a single wind speed acceleration wind turbine F1 or F2 is mounted (placed) on a moving body. However, power generation can be increased by placing two or more wind speed acceleration wind turbines adjacent to each other as needed.

[0075] Figure 19(a) shows an example of three wind speed acceleration wind turbines F2 arranged side by side. When arranging three of the same turbines, the overall amount of power generation can be increased by forming a space S between them as shown in Figure 19(b). Note that at least two wind speed acceleration wind turbines are required.
