DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] See also Figures 1 to 8 , the utility model provides a wind turbine.
[0030] The wind turbine includes a main pole 100 and a wind rotor module 200. The wind rotor module 200 includes a mounting tube 300 and a plurality of wind rotor power generation components 400. The mounting tube 300 is mounted on the main pole 100, and the plurality of wind rotor power generation components 400 are connected to the mounting tube 300. The two ends of the mounting tube 300 are respectively provided with a top plate 310 and a bottom plate 320. The top plate 310 is provided with a plurality of connection holes 311, and the bottom plate 320 is provided with a plurality of connection accessories 321. There are a plurality of wind rotor modules 200, and the plurality of wind rotor modules 200 are fixedly connected through a one-to-one matching of the plurality of connection holes 311 and the plurality of connection accessories 321.
[0031] Specifically, there are multiple connection holes 311 and connection accessories 321, multiple connection holes 311 are arranged in a ring at the top of the installation tube 300, and multiple connection accessories 321 are arranged in a ring at the bottom of the installation tube 300. The user can select the number of wind wheel modules 200 to be superimposed according to different scene requirements. For example: when the number of wind wheel modules 200 needs to be increased, another wind wheel module 200 can be installed on the wind wheel module 200, so as to gradually stack them. The steps of superimposing the wind wheel module 200 are as follows: align the connection accessories 321 on the new wind wheel module 200 with the connection hole 311 of the wind wheel module 200 located below it, and then connect the two through the connection accessories 321, etc. The connection accessories 321 can include two nuts and a screw, which is not specifically limited here, to ensure the stability of the connection between the two. With this arrangement, the wind turbine modularizes the wind wheel module 200, reduces the transportation and installation costs, and can determine the number of installation modules according to the wind field environment.
[0032] See also Figures 7 and 8Furthermore, a guide wing 500 is installed on the mounting tube 300, and the guide wing 500 has a first guide surface 510 and a second guide surface 520. The first guide surface 510 and the second guide surface 520 can divert wind flow and blow it out from both sides. The wind wheel power generation assembly 400 includes a generator module 410, a rotating rod 420 rotatably connected to the generator module 410, and a plurality of blades 430 connected to the rotating rod 420; each blade 430 has a wind receiving surface 431, wherein the wind receiving surface 431 of the blade 430 on one wind wheel power generation assembly 400 faces the direction of the wind diversion of the first guide surface 510, and the wind receiving surface 431 of the blade 430 on another wind wheel power generation assembly 400 faces the direction of the wind diversion of the second guide surface 520. It should be noted that the angle and position of the blade 430 in the existing wind turbine are fixed, and the wind turbine does not have a good wind diversion component, so that each blade 430 cannot maximize the use of wind energy, and the wind energy utilization rate is low. In the embodiment of the utility model, the wind blows through the tip of the guide wing 500 to divert the wind to both sides of the guide wing 500, so that the wind can flow along the first guide surface 510 and the second guide surface 520 on both sides of the guide wing 500. The wind blown out from the first guide surface 510 blows directly toward the blade 430 on the left wind rotor power generation assembly 400, and the wind blown out from the second guide surface 520 blows directly toward the blade 430 on the right wind rotor power generation assembly 400, so that it can push the blade 430 to drive the entire installation tube 300 to rotate, so as to realize the power generation of the generator module. For example: in the wind rotor power generation assembly 400 located on the left side, the first guide surface 510 of the guide wing 500 guides the wind to the wind receiving surface 431 of the left blade 430, and at the same time the structure of the guide wing 500 itself covers the blade 430 on the right side of the wind rotor power generation assembly 400, so that the left side of the entire wind rotor power generation assembly 400 is driven by the wind, while the right side is not blocked by the wind, and the clockwise rotation of the entire wind rotor power generation assembly 400 is smoother and faster, and the utilization rate of wind energy is maximized.
[0033] See also Figures 7 and 8 Furthermore, the wind receiving surface 431 is a concave arc surface. By concentrating the force of the wind on the concave part of the concave arc surface of the blade 430, it is prevented that the wind runs around and wastes wind energy, and the wind energy is utilized to the maximum extent.
[0034] See also Figures 7 and 8 Furthermore, the blade 430 is hook-shaped. After the wind hits the windward surface 431 of the blade 430, the wind hits the hook-shaped blade 430, thereby reducing the loss of wind volume, so that the blade 430 can maximize the use of wind energy and improve the power generation efficiency.
[0035] See also Figures 7 and 8Furthermore, in each wind turbine power generation assembly 400, a plurality of blades 430 are arranged in a circle around the rotating rod 420, and the arrangement of the plurality of blades 430 is expressed as follows: one blade 430 can replace the position of another blade 430 after rotating a corresponding angle. In this way, when the plurality of blades 430 rotate around the rotating rod 420, the concave arc surface of the blade 430 can always face the wind guided by the first guide surface 510 or the second guide surface 520 on the guide wing 500, so that the wind blown by the first guide surface 510 and the second guide surface 520 can provide a greater thrust to the blade 430.
[0036] See also Figure 1 and Figure 7 Furthermore, the wind wheel module 200 also includes a weather vane 440, which is connected to the installation tube 300 and is arranged in a plate shape. The weather vane 440 is used to indicate the direction of the incoming wind. The arrangement of the weather vane 440 enables the installation tube 300 to rotate until the guide wing 500 faces the incoming wind direction. The wind blows through the tip of the guide wing 500 to divert the wind to both sides of the guide wing 500, so that the wind can flow along the first guide surface 510 and the second guide surface 520 on both sides of the guide wing 500. The wind blown out from the first guide surface 510 faces the blades 430 on the wind wheel power generation assembly 400, so that the blades 430 can be pushed to drive the entire installation tube 300 to rotate, thereby realizing power generation by the generator module.
[0037] See also Figure 7 Furthermore, the guide wing 500 is in a "V" shape. In this way, the "V"-shaped guide wing 500 can divide the wind into the first guide surface 510 and the second guide surface 520 on both sides, and effectively guide the wind.
[0038] See also Figures 7 and 8 , further, the first guide surface 510 and / or the second guide surface 520 are arc-shaped surfaces, and the first guide surface 510 and the second guide surface 520 gradually move away from each other from the direction of the guide wing 500 toward the wind vane 440. Specifically, only the first guide surface 510 may be an arc-shaped surface; only the second guide surface 520 may be an arc-shaped surface; or both the first guide surface 510 and the second guide surface 520 may be arc-shaped surfaces. In this way, when the wind blows, the wind is affected by the division of the tip part of the guide wing 500, so that the wind is diverted and blown out from both sides, and can blow along the first guide surface 510 and the second guide surface 520 to hit the concave part of the blade 430, providing thrust for the blade 430 to rotate clockwise or counterclockwise.
[0039] See also Figures 7 and 8Furthermore, the guide wing 500 is provided with a plurality of reinforcing ribs 530 on the first guide surface 510 and the second guide surface 520. In this way, the reinforcing ribs 530 can improve the structural strength of the guide wing 500, prevent the guide wing 500 from being deformed by excessive wind, improve the structural stability of the guide wing 500, and save material costs.
[0040] See also Figures 7 and 8 Furthermore, each reinforcing rib 530 is extended along the flow guiding direction on the first flow guiding surface 510 or the second flow guiding surface 520, and each reinforcing rib 530 is arranged in parallel. In this way, under the guidance of the reinforcing ribs 530 on the first flow guiding surface 510 and the second flow guiding surface 520, the wind energy is more concentrated, the wind energy loss is reduced, and the wind energy utilization rate is improved.
[0041] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
