Furthermore, the blade 33 of the present embodiment is of a two-section design, and includes a first blade portion 335 adjacent to the fulcrum 31 and having the inner side 333, and a second blade portion 336 away from the fulcrum 31 relative to the first blade portion 335 and having the outer side 334. The second blade portion 336 can swing backward relative to the first blade portion 335 (see fig. 4), the second blade portion 336 and the first blade portion 335 can be combined by a plurality of hinges 37, each hinge 37 is a spring hinge, so that the second blade portion 336 can automatically return to the non-swinging state shown in fig. 3 after swinging as shown in fig. 4. In practice, the vane 33 may be provided with a grid-like skeleton, and may be bonded to the skeleton with a canvas or other material, such as graphene, cloth, polymer, metal, nonmetal …, or other sheet materials.

The cushion bodies 34 are respectively located between the inner sides 333 of the blades 33 and the support frame 32, and each cushion body 34 is, for example, an upright strip made of rubber.

The baffles 35 are connected to the outer sides 334 of the blades 33, respectively, and each baffle 35 extends in an arc opposite to the direction of rotation of the blade 33 to help collect and guide wind.

Referring to fig. 1 to 4, the springs 36 are respectively disposed on the inner sides 333 of the blades 33 in a plurality of groups, the springs 36 on the same blade 33 are spaced from each other up and down, one end of each spring 36 is connected to the blade 33, and the other end is connected to the bracket 32.

The first wind guiding unit 1 is located between the blade units 3, and includes an upright first upright post 11, two first guide plates 12, and four first springs 13. The first guide plates 12 are respectively connected to the left and right sides of the first upright post 11 and respectively extend leftwards and rightwards, so that the oncoming wind can be respectively guided to the left and right blade units 3. Each first guide plate 12 has a first connecting end 121 connected to the first upright 11, and a first actuating end 122 opposite to the first connecting end 121 and not fixed. The first guide plate 12 can swing backward (see fig. 4) with the first connection end 121 as a rotation axis when receiving a strong wind force. The first springs 13 are arranged up and down in pairs and connected between the first guide plate 12 and the wind following unit 6, and are used for buffering the force of the first guide plate 12 swinging backwards.

The second air guide units 2 are arranged left and right and are respectively positioned in front of the blade units 3. Each second wind guiding unit 2 includes an upright second upright post 21, a second guide plate 22, and two second springs 23 spaced up and down. The second guiding plate 22 extends obliquely backward and toward the direction of the other second guiding plate 2, and has a second connecting end 221 connected to the second upright post 21, and a second actuating end 222 adjacent to the other second guiding plate 22 and not fixed relative to the second connecting end 221. The second guide plate 22 can swing backward with the second connection end 221 as a rotation axis (see fig. 4). The second spring 23 is disposed up and down, connected between the second guide plate 22 and the second upright 21, and used for buffering the force of the second guide plate 22 swinging backwards.

An air inlet space 20 located in front of the first guide plate 12 is formed between the second guide plates 22 of the second air guiding unit 2, and the second guide plates 22 are used for guiding air entering from the air inlet space 20 to blow toward the first guide plate 12 and the blade unit 3. The position of the second guide plate 22 of each second wind guiding unit 2 substantially covers the range of the blade unit 3 located right in front of the fulcrum shaft 31 of the blade unit 3 located behind the second wind guiding unit and the range of the blade unit 3 close to the first wind guiding unit 1. That is, the left second guide 22 covers a portion directly in front of the support shaft 31 of the left blade unit 3 and a portion of the left blade unit 3 located on the right side of the support shaft 31. The second guide plate 22 on the right shields the support shaft 31 of the blade unit 3 on the right and the portion of the blade unit 3 on the left side of the support shaft 31, so that the wind can be guided to enter the wind intake space 20 and then be blown toward the blade unit 3.

The first positioning units 4 are respectively disposed on the leeward surfaces 332 of the blades 33 and adjacent to the outer sides 334 of the blades 33. Each first positioning unit 4 includes a plurality of upper and lower spaced slide rails 41, a plurality of hooks 42, and a plurality of elastic pushing members 43. The slide rails 41 are provided for one of the hooks 42 to be installed in a pair, and the slide rails 41 extend along the radial direction of the support shaft 31 to enable the hooks 42 to slide back and forth along the radial direction of the support shaft 31. Each hook 42 extends in an arc shape along the rotation direction of the blade 33 and has a hook-shaped end. Each elastic pushing member 43 is a spring, one end of which is connected to the blade 33, and the other end of which is connected to the corresponding hook 42, and the elastic pushing member 43 is used for providing a force to the hook 42 in a direction constantly facing the supporting shaft 31.

When the present invention is implemented, one of the hooks 42 may also be disposed by only matching one of the slide rails 41, for example, by increasing the upper and lower widths of the slide rail 41, a single hook 42 may be mounted on a single slide rail 41. In addition, in the embodiment, two elastic pushing members 43 are connected to one hook 42 in a group, but in practice, only one elastic pushing member 43 may be connected to one hook 42. In addition, the number of the sliding rail 41, the hook 42 and the elastic pushing element 43 of each first positioning unit 4 may be one, and it is not necessary to arrange a plurality of upper and lower parts.

The second positioning units 5 are respectively disposed on the second guide plates 22 of the second wind guiding unit 2 and adjacent to the second actuating ends 222. Each second positioning unit 5 includes a plurality of vertically spaced fastening holes 51 into which the corresponding fastening hooks 42 can extend. When the corresponding hook 42 is inserted into the locking hole 51, the front and rear corresponding blade units 3 and the second wind guiding unit 2 can be fixed. The number of the locking holes 51 of each second positioning unit 5 matches with the number of the hooks 42 of each first positioning unit 4, for example, when the number of the hooks 42 is one, the number of the locking holes 51 is only one.

The wind tracking unit 6 includes a vertical fixed shaft 61 located in front of the first wind guiding unit 1, a rotating shaft 62 surrounding the fixed shaft 61 and capable of being driven to rotate around the fixed shaft 61, a plurality of bearings 63 located between the fixed shaft 61 and the rotating shaft 62, a plurality of connecting rods 64 extending from the rotating shaft 62, and a wind tracking guiding plate 65 extending backward from the first upright post 11 of the first wind guiding unit 1. The connecting rod 64 connects the blade unit 3, the first air guide unit 1, and the second air guide unit 2. The link 64, the rotating shaft 62, and the wind deflector 65 are capable of deflecting in accordance with the direction of the wind together with the blade unit 3, the first wind guide unit 1, and the second wind guide unit 2. The wind-following deflector 65 is fixedly connected to the first column 11, and the wind-following deflector 65 has two wind-receiving surfaces 651 facing left and right, respectively.

In the present invention, when wind comes from the front of the second wind guide unit 2, part of the wind directly flows through the wind inlet space 20 to the first wind guide unit 1, and part of the wind flowing toward the second guide plate 22 is guided by the obliquely extending form of the second guide plate 22, and thus flows through the wind inlet space 20 to the first wind guide unit 1. The first guide plate 12 extends in the left-right direction, and can guide the oncoming wind to the left and right, respectively, so that the wind blows toward the blade unit 3, and further drives the blades 33 of the blade unit 3 to rotate, thereby achieving the purpose of wind-driven operation, and the rotation directions of the two blade units 3 are opposite. Each blade unit 3 may be connected to a not shown power generating device by which kinetic energy of the operation of the blade unit 3 is converted into electrical energy.

Referring to fig. 1, 3 and 4, it should be noted that, in a normal operation state, the vane 33 of each vane unit 3 rotates together with the bracket 32 in the state of fig. 3. However, when the wind force is large, several of the blades 33 of each blade unit 3 adjacent to the windward side can swing backward relative to the support frame 32 as shown in fig. 4 (the first blade portions 335 of two of the blades 33 of each blade unit 3 of fig. 4 have swung backward relative to the state of fig. 3), and the second blade portions 336 of the two blades 33 also swing backward relative to the first blade portions 335 thereof, on the other hand, the blade 33 in the leeward side still assumes the same state as that of fig. 3. That is, when the wind force is large, the entire blade 33 rotates with the bracket 32 relative to the support shaft 31 in the state of fig. 4. The blade 33 can swing backward relative to the bracket 32, and the blade 33 has the two-section first blade part 335 and the second blade part 336, so that the whole blade 33 is not strongly affected by wind, but can automatically collapse when the wind is strong, and the blade 33 is prevented from being blown off due to direct hard touch of the blade 33 and the wind.

The spring 36 of the blade unit 3 is used to provide a buffering restoring force to the blade 33, on one hand, to buffer the force of the blade 33 swinging backward relative to the bracket 32, and on the other hand, to bring the blade 33 back to the position of fig. 3 automatically from the position of fig. 4 when the wind force is weakened. The cushion body 34 of the blade unit 3 functions to prevent a collision, and when any one of the blades 33 swings backward from the position of fig. 3 to the position of fig. 4, the inner side 333 of the blade 33 hits the cushion body 34 instead of directly hitting the bracket 32 made of a hard material, so that the cushion body 34 can protect the blade 33 and the bracket 32.

In addition, each first guide plate 12 of the first air guiding unit 1 is also designed to be automatically collapsible, and when the wind is strong, the first guide plate 12 can swing backwards (as shown in fig. 4) with the first connecting end 121 as the rotating axis, so as to prevent the first guide plate 12 from being damaged by strong wind. The first spring 13 can buffer the force of the first guide plate 12 swinging backwards on the one hand, and can pull the first guide plate 12 back to the original position of fig. 3 through the elastic force of the first guide plate when the wind force is weakened on the other hand. Similarly, the second guide plate 22 of the second wind guiding unit 2 is also designed to be automatically collapsible, and when the wind is strong, the second guide plate 22 can swing backwards (as shown in fig. 4) with the second connection end 221 as the rotation axis, so as to prevent the second guide plate 22 from being damaged by the strong wind. The second spring 23 can buffer the force of the second guide plate 22 swinging backward, and can pull the second guide plate 22 back to the original position as shown in fig. 3 by its elastic force when the wind force is weakened.

Referring to fig. 2 and 5, further, when the second guide plate 22 is blown to swing by a larger angle, so that the second operation end 222 is close to any blade 33 in the rotation of the blade unit 3, the hooks 42 on the blade 33 respectively extend into the locking holes 51 on the second guide plate 22, and further the blade unit 3 and the second wind guiding unit 2 are locked and fixed together, so that the blade unit 3 and the second wind guiding unit 2 can not rotate freely due to strong wind, thereby having a protection effect. The elastic pushing member 43 of the first positioning unit 4 provides a constant force toward the fulcrum 31 from the hook 42, which is equivalent to a force for providing the hook 42 for fastening and combining with the locking hole 51, thereby enhancing the fixing effect. In addition, since the hook 42 can slide along the slide rail 41, when the fixed relationship between the hook 42 and the hole 51 is to be released, the hook 42 is pushed toward the elastic pushing member 43 and the blade 33 is slightly pulled away from the second guide plate 22, so that the hook 42 can be disengaged from the hole 51.

It should be noted that each of the fastening holes 51 may be provided therein with a cushion body, not shown, made of rubber or other soft material, which has anti-collision and protection functions, so that when the fastening hook 42 extends into the fastening hole 51, the cushion body will collide with the fastening hook 42, thereby preventing the fastening hook 42 from directly and rigidly colliding with the second guide plate 22. In addition, a solar panel or a power generation glass, not shown, can be installed on the top of the device. Referring to fig. 1, the device of the present invention can also be horizontally erected, wherein the first upright 11, the second upright 21, the support shaft 31, the fixed shaft 61, the rotating shaft 62, and other elements are horizontal. In practice, a lift-type blade, not shown, may be attached to the top of the fulcrum 31 of each blade unit 3.

Referring to fig. 6, it should be noted that, by the design of the wind-following unit 6, the device of the present invention can use the fixed shaft 61 as the rotation axis, and the blade unit 3, the first wind guiding unit 1 and the second wind guiding unit 2 can deflect to the proper wind-receiving angle position along with the direction of the wind. In addition, if the wind comes from the side of the wind-following guiding plate 65 and blows towards one of the wind-receiving surfaces 651, the wind-following guiding plate 65 will be blown and deflected (for example, deflected from the state of fig. 3 to the state of fig. 6), so as to drive the first wind guiding unit 1 to rotate, and drive the second wind guiding unit 2 and the blade unit 3 to deflect to the proper angle position through the rotating shaft 62. Therefore, no matter the first wind guiding unit 1 and the second wind guiding unit 2 are windingly linked with other elements to turn, or the wind following guide plate 65 is windingly linked with other elements to turn, the device can automatically rotate to a proper angle position, thereby achieving the best wind inlet and collecting effect, effectively utilizing the wind force and coping with the unstable condition of the wind direction.

In summary, the first wind guiding unit 1 and the second wind guiding unit 2 can guide the wind to the left and the right and respectively blow to the blade unit 3, which is a design of the double-wind driven double-blade unit 3, compared to the conventional wind blade device without the first wind guiding unit 1 and the second wind guiding unit 2, the present invention can effectively collect and guide the wind to blow to a proper position, so as to make the most effective use of the wind force and improve the operation efficiency.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
