The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to Figure 1, a preferred embodiment of the enclosed wind power plant of the present invention comprises a wind power plant 100 comprising a wind hood 1, a rotating mechanism 2, a generator 3 and a first blower module. Group 4, wherein the external airflow enters the hood 1 and then drives the rotating mechanism 2 through the rotating mechanism 2, whereby the generator 3 connected to the rotating mechanism 2 generates electric power, and in the diagram of the embodiment, The dimensions of the collecting hood 1 and the rotating mechanism 2 are only schematic, and the actual dimensions thereof may vary depending on the actual application.

The windshield cover 1 includes a casing tube 11, a plurality of pressing fans 15 and a connecting pipe 16, and the casing tube 11 has an air inlet end 111 and an air outlet end 112 facing away from the air inlet end 111. The air inlet end 111 is formed with an air inlet 111a. The air outlet end 112 is formed with an air outlet 112a. The air inlet 111a has a larger diameter than the air outlet 112a. In this embodiment, the casing tube 11 can be separated into a connected front section 11a. And a rear section 11b, the front section 11a defines an air inlet end 111 and the rear section 11b defines an air outlet end 112, and the front section 11a is substantially conical tubular and the air inlet end 111 is substantially flared. The diameter of the front section 11a is from the air inlet 111a. The direction of the rear section 11b is gradually reduced. Since the front section 11a is a conical tube shape, the cross-sectional geometry of the cross section is the same, and the loss generated when the airflow flows from the air inlet 111a to the rear section 11b can be reduced. The structure of the air inlet end 111 can also be arranged to be radially expandable and contractible, and the specific aspect of the radially expandable and contractible can be, for example, a telescopic structure or a detachable structure, so as to facilitate The size of the air inlet 111a is adjusted. When the air inlet end 111 is radially expanded to increase the diameter of the air inlet 111a, a large amount of airflow can be entered into the casing tube 11 when the air inlet end 111 is radially contracted. When the diameter of the air inlet 111a is reduced, a small amount of airflow enters the casing tube 11. The rear section 11b has a square tubular connection front section 11a and a rotating mechanism 2.

Regarding the taper of the front section 11a of the casing tube 11, with reference to Fig. 2, wherein the angle θ can be about 10 degrees, especially at 6 degrees, the front section 11a is lowered by elongating the length of the front section 11a of the entire casing tube 11 The tapered slope helps to increase the wind speed in the front section 11a of the casing tube 11. Further, A ₁ and A ₂ represent the area of the air inlet 111a and the air outlet 112a, respectively, and the area ratio between A1 and A2 is 3~5. Preferably, for example, if the area of the air inlet 111a is four times the area of the air outlet 112a, the minimum wind speed required to start the rotation of the rotating member 22 of the rotating mechanism 2 and drive the generator 3 to generate electricity is 3 m/s. , based on A ₁ ‧V ₁ =A ₂ ‧V ₂ , the wind speed entering the air inlet 111a only needs 3÷4=0.75m/s, so the taper design of the front section 11a of the casing tube 11 is even wind speed In a weaker case, power generation can be operated in the same manner, and the time during which the wind power generator 100 operates to generate electricity can be increased.

The pressing fan 15 is fixedly disposed in the front portion 11a of the casing tube 11 (for example, through a screw lock or the like). With the arrangement of the pressing fans 15, when the external air volume is weakened, the casing can be pressurized into the casing tube. The air flow of 11, in Fig. 1, a pressure fan 15 is provided at a cross-sectional position of each of the casing tubes 11, but it is also possible to provide a plurality of pressure fans 15 at each cross-sectional position of the casing tube 11.

The first blower module 4 includes a first blower (Turbo Blower) 41, a first air inlet duct 42, and a first air outlet duct 43. The first blower 41 is disposed adjacent to the outer side of the casing tube 11. The first air inlet duct 42 connects the casing tube 11 and the first air blower 41, so that the airflow in the casing tube 11 can enter the first air blower 41 via the first air inlet duct 42. One end of the first air outlet duct 43 is connected to the first air blower 41, and the other end extends into the air outlet port 112a of the casing tube 11 which is located in the rear portion 11b of the casing tube 11. The first air outlet duct 43 extends into the rear portion 11b of the casing tube 11, and the end outlet diameter of the first air outlet duct 43 toward the air outlet 112a of the casing tube 11 is preferably about the air outlet 112a of the casing tube 11. One-half of the diameter of the aperture, as shown in FIG. 3, the diameter of the end of the first outlet duct 43 may also be elliptical.

The rotating mechanism 2 includes a first outer casing 21, a rotatable rotating member 22 disposed in the first outer casing 21, a movable shutter 20, and a transmission shaft 25. The first outer casing 21 has a first opening 211 that communicates with the air outlet 112a of the casing tube 11. In this embodiment, the connecting tube 16 of the air collecting hood 1 is connected between the rear portion 11b of the casing tube 11 and the first outer casing 21. The rear portion 11b of the casing tube 11 is connected to the first opening 211 by the connecting tube 16, and the movable shutter 20 is disposed at a position of the first outer casing 21 adjacent to the first opening 211 and is adjustable to move relative to the first outer casing 21 to adjust the first opening 211 is connected to the size of the air outlet 112a. The rotating member 22 includes a central rotating shaft 221 and a plurality of blades 222 surrounding the central rotating shaft 221. The central rotating shaft 22 is dynamically coupled to the generator 3 via a transmission shaft 25, and the blades 222 can rotate along the central axis of the central rotating shaft 221 along with the central rotating shaft 221 and pass through. The first opening 211 of the first outer casing 21.

Each of the blades 222 has a windward surface 222a and a leeward surface 222b. The blades 222 are actuated by the windward surface 222a being blown by the airflow, and each of the leeward faces 222b is tapered, whereby the blades 222 are airflowed. When the rotation is blown, the wind resistance received by the leeward surface 222b of the blade 222 can be reduced.

When the airflow enters the casing tube 11 from the air inlet 111a, it is first pressurized via the section of the pressurizing fan 15, and then a portion of the airflow that is segmentally pressurized in the casing tube 11 enters the first portion via the first air inlet duct 42. The air blower 41 is blown toward the air outlet 112a of the casing tube 11 through the first air outlet pipe 43 and blown toward the blade 222, and the diameter of the first air outlet pipe 43 to the air outlet 112a of the casing tube 11 can be tapered. By increasing the wind speed, when the airflow from the air inlet 111a of the casing tube 11 to the air outlet 112a is blown toward the blade 222, the blade 222 can be rotated, and the generator shaft 3 is driven to generate electricity through the center shaft 221 and the transmission shaft 25.

Referring to FIG. 4, the first air outlet duct 43 functions to increase the speed of the first air outlet duct 43 because the airflow blown to the air outlet 112a of the casing tube 11 is increased by the first air blower 41. When going to the air outlet 112a of the casing tube 11, based on the white law (Bernoulli Law), the pressure on both sides of the airflow discharged from the first air outlet tube 43 in the casing tube 11 is lowered to form a negative pressure. It also helps to allow more outside airflow to enter the air inlet 111a of the casing tube 11 due to the pressure difference. Based on the white effort law, when the fluid flow rate is increased, the pressure thereof is lowered. Therefore, by accelerating the airflow by the first air outlet pipe 43, the rear portion 11b of the casing tube 11 can be blown by the first air outlet pipe 43. The pressure around the airflow is reduced, and the airflow around the rear section 11b of the casing tube 11 is accelerated. For example, the ratio of the aperture area of the first air outlet duct 43 to the outlet diameter of the air outlet 112a of the rear section 11b is 1:2. The flow rate of the airflow blown by the first air outlet pipe 43 is 1 unit, which drives the air outlet 112a of the rear section 11b into the first outer casing 21 and the total flow velocity to the blade 222 is preferably up to 3 times the flow rate, based on the wind energy density.

Since V ³ and V are extremely different, for example, when V = 3 m/s, V ^{3 is} 27 m/s, and therefore, the flow rate for the gas flow can be greatly increased.

W(total work)=w×A

Therefore, the increase in the flow rate contributes to an increase in the power applied to the unit area of the blade 222, thereby improving the kinetic energy of the operation of the rotating member 22.

Therefore, if the taper design of the front section 11a of the casing tube 11 is used to increase the flow velocity of the airflow by a factor of four, and then the design can be increased to a flow rate of three times, theoretically, when the airflow enters the front section 11a of the casing tube 11 until When entering the first outer casing 21 and blowing toward the vane 222, the flow rate can be increased up to a maximum of 12 times. Of course, the actual operation still causes loss.

Referring to FIG. 5, preferably, the windshield 1 further includes a rectifying unit 12 disposed in the casing tube 11 and interposed between the air inlet 111a and the air outlet 112a. In this embodiment, The rectifying unit 12 is disposed at a junction of the front section 11a of the casing tube 11 adjacent to the rear section 11b, and the rectifying unit 12 includes a plurality of straight tubular passages 121 extending linearly. Since the casing tube 11 has a tapered shape, when the airflow flows from the air inlet 111a of the casing tube 11 to the air outlet 112a, the airflow traveling adjacent to the inner wall surface of the casing tube 11 is more likely to cause turbulent flow, and therefore, by the rectifying unit 12 The arrangement can guide a part of the airflow to advance in a straight line direction, reduce the generation of turbulent flow, and reduce the loss generated by the airflow in the process of flowing from the air inlet 111a of the casing tube 11 to the air outlet 112a, in other words, due to the casing tube 11 Since it is tapered, the flow entering the casing tube 11 can be rectified into a laminar flow state by the arrangement of the rectifying unit 12, thereby reducing flow loss. The specific structure of the rectifying unit 12 may be formed by providing a plurality of partitions in the circular tube, and the rectifying unit 12 may also include a plurality of circular tubes that are bored to form a structure of inner and outer layers. For example, FIG. 5 has two layers inside and outside.

The end of the second air outlet pipe 53 adjacent to the rotating member 22 can be substantially positioned at the blade 222 of the rotating member 22 through the first outer casing 21. The position downstream of the first opening 211.

Preferably, the end of the second outlet duct 53 adjacent to the rotating member 22 can be flat or beveled to increase the speed at which the airflow is blown out by the second outlet duct 53.

Referring to FIG. 6 , the second air blower module 5 further includes a movable member 54 that can be disposed to slide into the casing tube 11 along the length of the second air inlet duct 52 or to exit the casing tube 11 . By the arrangement of the movable member 54, when the second blower module 5 needs to extract a relatively large amount of airflow from the casing tube 11, the movable member 54 can be driven into the casing tube 11, thereby intercepting a relatively large amount of airflow into the first The second air duct 52 and the movable member 54 may be, for example, a tubular body that is disposed through the second air inlet duct 52 and has a beveled nozzle 541 for extending into the casing tube 11.
