According to the wind collecting device 1 having such a configuration, the flow of the wind volume in the natural environment is shaved on the front side of the wind collecting unit 2 (wind shaving), and the wind is collected and sent to the rear side. And since the discharge port 5 is provided below the upper end of the front surface of the air collection part 2, and the air flow collection part 2 has a flow-path cross-sectional area becoming small as it goes to the rear surface side from the front side, the height of a wind is lowered. Thus, the volume of the normal pressure wind can be efficiently discharged from the discharge port 5 after being reduced to a high density and high pressure.
Moreover, since the air collection part 2 has the cavity part (cavity part of the air mats 12 and 12A) with which air is filled, while being able to achieve weight reduction of the air collection part 2, the air collection part 2 Since the balloon 50 having buoyancy in the atmosphere is connected to the upper end of the air collecting portion 2, the air collecting portion 2 is difficult to bend downward due to its weight, and wind can be collected efficiently.
Furthermore, since the weight 55 is connected to the lower end portion of the air collecting unit 2, the air collecting unit 2 can be opened widely by the balloon 50, and therefore, the size can be easily increased.

Further, the balloon 50 obtains buoyancy upward in the atmosphere by hot air, and pulls the upper wall portion 4 upward. By using this tensile force, the upper wall portion 4 constituted by the air collecting units 10 and 10A having the air mats 12 and 12A and the air collecting units 10 and 10A having the air mats 12 and 12A connected thereto are used.

Therefore, since these weights 555 balance against the buoyancy of the balloon 50, the air collecting portion 2 can be opened widely and the discharge port 5 can be opened reliably. For this reason, the wind which collected wind is discharged from the discharge port 5, and the wind force of this wind can be utilized effectively.

The air collecting part 2 has a pair of left and right side wall parts 3 and 3 and an upper wall part 4 constructed between the pair of side wall parts 3 and 3. Since the upper wall portion 4 is disposed so as to be inclined downward from the front surface side of the air collecting portion 2 toward the rear surface side, as it approaches the rear surface side from the front surface side of the portion 2, The discharge port 5 can be easily provided below the upper end of the front surface of the air collecting unit 2, and the flow passage cross-sectional area of the air collecting unit 2 can be easily reduced from the front side toward the rear side.

In addition, in this Embodiment, although the cylindrical body 31 was made into the cylindrical shape, it does not restrict to this. For example, as long as the cylindrical body 31 is cylindrical, it may be a quadrangular cylindrical or more polygonal cylindrical shape, an elliptical cylindrical shape, or a long cylindrical shape. Moreover, the cylindrical body 31 is not limited to a linear shape, and may be a curved shape. If it does in this way, the direction of the flow of a wind can be bent dynamically and the polluted air in a big city can be blown away to a desired place. Moreover, the some axial part extended in the axial direction may be provided in the inside of the cylindrical body 31, and the several impeller 32 may be provided in each axial part, respectively.

In addition, since the impeller 32 is provided inside the cylindrical body 31, wind (air) hitting the impeller 32 does not escape to the outside and the wind pressure does not decrease, and the wind is efficient in all the impellers 32. Therefore, power can be generated efficiently.
In addition, the impeller 32 includes a support member 33 that is supported by the shaft portion 25, and a rotating body 35 that is rotatably provided on the support member 33 via a bearing 34 and that has a blade 36 on the outer peripheral portion. Therefore, the number of impellers 32 provided on the shaft portion 25 can be easily increased or decreased. Therefore, the capability of the wind power generator 30 can be easily adjusted according to the wind force and the air volume.

Further, since the wind power generator 30 is housed inside the storage unit 20, the wind power generator 30 can be protected by the storage unit 20 and can be easily installed at a desired location. And handling at the installation site becomes easy.
In addition, since the leading impeller 32 of the wind power generator 30 is located on the front end surface side of the storage unit 20, wind is received from the front end surface and easily flows into the cylindrical body 31 to be impeller. 32 can be rotated.
Furthermore, the installation number and installation position of the wind power generation units 61 can be easily adjusted by stacking the storage units 20 or connecting them horizontally.

Further, since the front end surface of the storage unit 20 of the wind power generation unit 61 is connected to the discharge port 5 of the wind collector 1, the air taken into the wind collector 1 is collected and discharged from the discharge port 5. The discharged wind can flow into the cylindrical body 31 from the front end surface of the storage unit 20. Therefore, wind can be efficiently supplied to the wind power generator 30 to generate power.

Further, the flow of the wind volume of the natural environment is shaved on the front side of the wind collecting unit 2 (wind shaving), and the wind is collected and sent to the rear side. And since the discharge port 5 is provided below the upper end of the front surface of the air collection part 2, and the air flow collection part 2 has a flow-path cross-sectional area becoming small as it goes to the rear surface side from the front side, the height of a wind is lowered. Thus, the volume of the normal-pressure wind can be discharged from the discharge port 5 after being reduced to a high density and high pressure. The wind discharged from the discharge port 5 becomes high-density and high-pressure and rectifies. Therefore, this flow is guided to the inside of the cylindrical body 31 and continuously applied to the impellers 32 provided coaxially therein. Thus, by rotating the impeller 32, power can be generated more efficiently.
Further, by rotating the impeller 32, the air compressor can be rotated to store the compressed air in a high-pressure tank and used for the compressed air wheel, and the oxygen compressor can be rotated to be stored in the oxygen tank.
Further, by providing a filter at the discharge port 5, foreign matters such as dust and dust contained in the wind (air) taken in by the air collecting unit 2 can be removed, so that air can be purified together with power generation.
Further, the wind collecting device 1 can be used separately from the wind power generation unit assembly 60. In this case, by providing an air filter at the outlet 5 of the air collecting unit 2 of the air collecting device 1 to collect moisture, drinking water can be produced on an island with little rain water. Furthermore, the power of the typhoon can be weakened by removing moisture from the wind.

Moreover, since the relatively heavy wind power generation unit assembly 60 is provided on the ground after being provided at the lower part on the back side of the wind collecting device 1, the wind collecting device 1 can be stably installed, and wind power generation is also possible. Maintenance of the wind turbine generator 30 in the unit 61 can be easily performed.

In addition, the wind power generation equipment is installed on a rotary table that can be rotated by a drive source such as a motor, and the power generated by the wind power generator 30 is supplied to the drive source so that the wind power generation equipment can be rotated around the vertical axis by the rotary table. And the rotation angle may be controllable. Accordingly, the wind power generation facility can be controlled to rotate so that the front surface of the wind collecting device 1 is directed in the direction in which the wind blows, so that power can be generated efficiently.
