The discharge port 45a is provided below the upper end of the front surface of the wind collecting portion 43, and the flow path cross-sectional area of the wind collecting portion 43 becomes smaller from the front side to the rear surface side of the wind collecting unit 40. After lowering the height of the wind to reduce the volume of normal pressure wind to high density and high pressure, it can be discharged from the discharge port 45a. Since the wind discharged from the discharge port 45a becomes high density and high pressure and is rectified, this flow is guided to the inside of the tubular body 31 and continuously applied to a plurality of impellers 32 coaxially provided inside the inside. Therefore, by rotating the impeller 32, it is possible to generate electricity more efficiently.
Further, by rotating the impeller 32, the air compressor can be rotated to store the compressed air in the high-pressure tank and used for the compressed air car, and the oxygen compressor can be rotated to store the compressed air in the oxygen tank.
Further, by providing the filter at the discharge port 45a, foreign substances such as dust and dirt contained in the wind (air) taken in by the air collecting unit 43 can be removed, so that the air can be purified as well as the power generation.
Further, the wind collecting unit 40 can be used separately from the wind power generation unit 1. In this case, drinking water can be produced on an island or the like where there is little rainwater by providing an air filter at the discharge port of the wind collecting unit 43 of the wind collecting unit 40 to collect moisture. Furthermore, the force of the typhoon can be weakened by removing the moisture of the wind.

Further, since the support frame 42 of the wind collecting unit 40 is assembled by a plurality of rod-shaped structural members 41, the size of the support frame 42 can be adjusted by increasing or decreasing the number of the structural members 41 used.
Further, the rear frame portion 45 is connected to the front frame portion 44 so that its upper surface is located below the upper surface of the front frame portion 44 and its side surface is located inside the side surface of the front frame portion 44. , A plurality of front wind collecting plates 46 (46a to 46d) are attached to the front frame portion 44 so as to face the front surface of the rear frame portion 45, and a plurality of rear wind collecting plates 47 (47a to 47a) are attached to the rear frame portion 45. Since 47d) is attached so as to face the discharge port 45a, the wind taken into the air collecting portion 43 is surely flowed from the front air collecting plate 46 toward the rear air collecting plate 47 and is located on the lower side. It can be discharged from the discharge port 4a. That is, since the wind taken in by the wind collecting unit 43 and collected can be discharged from the discharge port 45a located on the lower side, the wind power generation unit 1 can be installed on or near the ground, for example.
Further, since the front wind collecting plates 46 (46a to 46d) and the rear wind collecting plates 47 (47a to 47b) can increase their own weight by absorbing moisture, for example, in the event of a typhoon or the like. Since the front wind collecting plates 46 (46a to 46d) and the rear wind collecting plates 47 (47a to 47b) become heavier by absorbing moisture, the wind power generation facility 50 can withstand the wind of a typhoon.

Further, since the relatively heavy wind power generation unit 1 is installed on the ground after being provided at the lower part on the back side of the wind power generation unit 40, the wind power generation unit 40 can be stably installed and the wind power generation unit 1 can be installed stably. Maintenance of the wind power generator 30 inside can be easily performed.

Further, the wind power generation facility 50 is installed on a rotary table or the like that can be rotated by a drive source such as a motor, and the electricity generated by the wind power generation device 30 is supplied to the drive source to vertically rotate the wind power generation facility 50 by the rotary table. In addition to rotating around the axis, the rotation angle may be controllable. As a result, the wind power generation facility 50 can be rotated and controlled so that the front surface of the wind collecting unit 40 faces the direction in which the wind blows, so that power can be generated efficiently.
