DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Embodiment 1:

[0034] Reference Figures 1 to 5 As shown, this embodiment provides a multi-stage pipeline wind power generation device, including

[0035] The first pipeline 1 is provided with an air conveying mechanism inside;

[0036] A plurality of power generation components are detachably connected to one end of the first pipeline 1 in sequence;

[0037] A flow guiding mechanism is arranged in the power generation assembly, and is used to guide the air entering the power generation assembly;

[0038] When the air conveying mechanism is in a first posture, air enters the power generation component through the first pipe 1, and the power generation component converts the kinetic energy of the air into electrical energy for storage. When the air conveying mechanism is in a second posture, the amount of air entering the power generation component is increased.

[0039] The power generation component is set up so that the air force entering the first pipeline 1 can be converted into electrical energy, and the converted electrical energy is used to power the air conveying mechanism, so that the air conveying mechanism is changed from a first posture to a second posture, thereby increasing the flow speed of air in the device, thereby improving the power generation efficiency of the power generation component. The set guide mechanism guides the air entering the inside of the device, so that the air flow acts on the power generation component more efficiently, thereby improving the utilization rate of wind energy.

[0040] Furthermore, the air conveying mechanism includes a support rod 9, which is fixedly arranged on the inner wall of the first pipe 1, and the support rod 9 is vertically arranged. A driving motor 10 is fixedly embedded in the middle of the support rod 9. A fixing ring 12 is provided on the output shaft of the driving motor 10. A plurality of fan blades 11 are rotatably connected to the outer wall of the fixing ring 12. The plurality of fan blades 11 are circumferentially evenly arranged along the outer wall of the fixing ring 12, and an angle adjustment part is movably connected to one end of each fan blade 11 close to the fixing ring 12.

[0041] Furthermore, the cross-section of the outer wall of the fixing ring 12 is hexagonal.

[0042] Furthermore, the rotation direction of the fan blades 11 is spatially perpendicular to the rotation direction of the output shaft of the drive motor 10 .

[0043] Furthermore, when the fan blade 11 is parallel to the cross-sectional plane of the output shaft axis of the drive motor 10 , it is in the first posture; when the fan blade 11 is at an angle to the cross-sectional plane of the output shaft axis of the drive motor 10 , it is in the second posture.

[0044] Furthermore, the angle adjustment part includes a telescopic rod 15, a fixed end of the telescopic rod 15 is fixedly connected to the outer side wall of the fixing ring 12, the telescopic end of the telescopic rod 15 is fixedly connected to a fixing seat 16, the fixing seat 16 is rotatably connected to one end of a rotating shaft 17, the other end of the rotating shaft 17 is fixedly connected to a slip ring 18, a sliding rod 14 is slidably penetrated inside the slip ring 18, the fan blade 11 is rotatably connected to the outer side wall of the fixing ring 12 through a connecting shaft 13, and one end of the sliding rod 14 is fixedly connected to the outer side wall of the connecting shaft 13.

[0045] When the fan blade 11 is in the first posture, the outside air enters the second pipe 2 and the third pipe 3 from the first pipe 1 and acts on the power generation component. The power generation component converts the wind energy into mechanical energy and further converts it into electrical energy. The converted electrical energy acts on the drive motor 10. The drive motor 10 drives the fan blade 11 to rotate, thereby increasing the amount and speed of air entering the second pipe 2 and the third pipe 3, thereby improving the wind energy conversion efficiency of the power generation component and converting more electrical energy. At this time, part of the converted electrical energy is input into the power storage device for storage, and the other part continues to act on the drive motor 10 to keep the rotation of the fan blade 11. At the same time, the telescopic end of the telescopic rod 15 is extended, and the angle of the fan blade 11 is changed through the fixed seat 16, the slip ring 18 and the slide rod 14, so that the fan blade 11 is changed from the first posture to the second posture. When the fan blade 11 is in the second posture, there is a certain angle with the flow direction of the air. Through the existence of the angle, the fan blade 11 further accelerates the flow speed of the air in the device while rotating, thereby further improving the conversion efficiency of the power generation component to wind energy.

[0046] Furthermore, the power generation component includes a second pipeline 2 and a third pipeline 3. The first pipeline 1 and the second pipeline 2, and the second pipeline 2 and the third pipeline 3 are all detachably connected through a plurality of self-locking mechanisms. The third pipeline 3 is located at an end of the second pipeline 2 away from the first pipeline 1. A guide portion is provided in the second pipeline 2, and a power generation portion is provided in the third pipeline 3.

[0047] The number of the second pipes 2 and the third pipes 3 installed on the first pipe 1 is changed by a self-locking mechanism, and the specific number of the second pipes 2 and the third pipes 3 is increased according to the actual power generation requirements. When there are multiple second pipes 2 and third pipes 3, several second pipes 2 and third pipes 3 need to be arranged at intervals, that is, one third pipe 3 is arranged between two second pipes 2, and one second pipe 2 is arranged between two third pipes 3. The air entering the device is guided through the second pipe 2. It is also possible not to install the second pipe 2, and only install several third pipes 3 on the first pipe 1 to generate electricity.

[0048] Furthermore, the self-locking mechanism includes a first ear 4 and a second ear 5. The first ear 4 is fixedly connected to the end of the outer wall of the second pipe 2, and the second ear 5 is fixedly connected to the end of the outer wall of the third pipe 3. An insert plate 7 is commonly penetrated inside the first ear 4 and the second ear 5. After the insert plate 7 is inserted into the first ear 4 and the second ear 5, its two ends are exposed to the outside of the first ear 4 and the second ear 5. U-shaped buckles 6 are penetrated at both ends of the insert plate 7, and insertion rods 8 are commonly penetrated at both ends of the U-shaped buckle 6 and the inside of the insert plate 7.

[0049] When it is necessary to connect the first pipeline 1 and the second pipeline 2, and the second pipeline 2 and the third pipeline 3, align the first ear 4 and the second ear 5 at the ends of the two, then insert the plug plate 7 into the first ear 4 and the second ear 5, and then make the two ends of the U-shaped buckle 6 face downward and insert them into the two ends of the plug plate 7, and finally insert the plug rod 8 into the two ends of the plug plate 7 and the U-shaped buckle 6 to complete the connection of the first pipeline 1 and the second pipeline 2, and the second pipeline 2 and the third pipeline 3.

[0050] Furthermore, the guide part includes a guide ring 19, which is fixedly connected to the inner wall of the second pipe 2, and the inner wall of the guide ring 19 is an inclined surface. The large end of the inner wall of the guide ring 19 faces the first pipe 1, and the small end of the inner wall of the guide ring 19 faces the third pipe 3.

[0051] After the air enters the device, it enters from the large end of the guide ring 19 and acts on the inclined side wall of the guide ring 19, and flows out from the small end of the guide ring 19. Since the area of ​​the outflow end is smaller than the area of ​​the inlet end, the air speed increases when flowing out from the outflow end. The air with a large flow rate acts on the power generation part, thereby improving the conversion efficiency of wind power and electrical energy.

[0052] Furthermore, the power generation part includes a guide cover 21, which is fixedly connected to the inner wall of the third pipe 3 through a plurality of fixing rods 20, and a generator 22 is fixedly embedded inside the guide cover 21. The input shaft of the generator 22 is fixedly connected to a connecting ring 23, and the outer side wall of the connecting ring 23 is fixedly connected to a plurality of impellers 24, and the plurality of impellers 24 are arranged at equal intervals along the circumference of the connecting ring 23.

[0053] The air acts on the impeller 24 to drive the impeller 24 to rotate. When the impeller 24 rotates, it drives the generator 22 to work and convert wind energy into electrical energy. The deflector 21 guides the air to prevent the generator 22 from blocking the air and causing the flow rate of the air entering the next generator 22 to decrease.

[0054] The working process of this embodiment is as follows:

[0055] When the fan blades 11 are in the first posture, air enters the third pipe 3 and acts on the impeller 24, driving the impeller 24 to rotate. The impeller 24 drives the generator 22 to work and convert wind energy into electrical energy. The electrical energy converted by the generator 22 controls the drive motor 10 to work, and the drive motor 10 drives the fan blades 11 to rotate. While the fan blades 11 rotate, the telescopic rod 15 extends, and the inclination angle of the fan blades 11 is adjusted by the sliding rod 14, so that the fan blades 11 are transformed from the first posture to the second posture, and then combined with its own high-speed rotation, the flow speed of the air in the third pipe 3 is increased, so that the air acts on the impeller 24 at a higher speed, thereby improving the power generation efficiency of the device.

[0056] Embodiment 2:

[0057] Reference Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the inner side wall of the guide ring 19 includes two sections of inclined side walls, the small ends of the two sections of inclined side walls are close to each other and smoothly transition, and the large ends of the two sections of inclined side walls are far away from each other and are respectively located at the two ends of the guide ring 19. This embodiment reduces the influence of the guide ring 19 on the air flow rate through the design of smooth transition.

[0058] Embodiment three:

[0059] Reference Figure 7 As shown, the difference between this embodiment and embodiment 1 is that the inner side wall of the guide ring 19 includes two sections of inclined side walls, the inclination angles of the two sections of the inclined side walls are different, the connecting ends of the two sections of the inclined side walls are smoothly transitioned, and the side wall with a large inclination angle is close to the generator 22 side. By designing inclined side walls with different inclinations and smooth transitions, the influence of the guide ring 19 on the air flow velocity is further reduced.

[0060] Embodiment 4:

[0061] Reference Figure 8 As shown, the difference between this embodiment and the first embodiment is that the inner side wall of the guide ring 19 includes two sections of inclined side walls, the small ends of the two sections of inclined side walls are close to each other and smoothly transition, and the large ends of the two sections of inclined side walls are far away from each other and are respectively located at the two ends of the guide ring 19, and the middle part of the inner side wall of the guide ring 19 is fixedly connected with a guide body 26 through a plurality of supporting connecting rods 25. Through the guide body 26 and the inclined side wall of the guide ring 19, the high-speed flowing air completely acts on the impeller 24, thereby greatly improving the conversion efficiency between wind energy and electric energy.
