Description

Technical Field

[0001] This invention relates to the field of wind power generation components technology, particularly mobile wind turbine heads. Background Technology

[0002] With the increasing precision of global energy, the research and development of new pollution-free energy sources is growing, and wind power is a leading example.

[0003] Traditional wind turbine blades have a relatively simple structure and low wind energy utilization rate. They perform well in areas with strong winds, such as Northeast China; however, in areas with less wind, the power generation is less than satisfactory.

[0004] Currently, to improve power generation efficiency, companies have conducted extensive research and development on wind turbine blades. A common approach is to install multiple blades along the direction of wind. While these configurations can improve wind utilization to some extent, their structures are usually complex, resulting in significant weight. This weight affects the rotational speed of the shaft, making lightweight blade design a crucial design consideration. Furthermore, the wind direction changes as it acts on different layers of blades, meaning that each layer may not effectively utilize the wind.

[0005] Based on this, the inventor, drawing on years of experience in the industry, designed a new type of wind turbine head that reduces weight through a simple structure and makes good use of wind direction, thereby improving wind utilization. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mobile wind turbine head that has high wind energy utilization, simple structure, and compact design.

[0007] The objective of this invention is achieved through the following technical solution: a mobile wind turbine head, including a rotating shaft, and further comprising:

[0008] The second blade structure is formed by bending multiple blades B into the shape of a handmade windmill, and it is fitted onto the rotating shaft.

[0009] The leaf B has a root area that is larger than its tip area;

[0010] The wind blows at the base of blade B, causing the entire second blade structure to rotate.

[0011] Optionally, a third blade structure may also be included;

[0012] The root and end of the blade B are spaced apart to form an intermediate cavity;

[0013] The third blade structure is disposed in the middle cavity and sleeved on the rotating shaft;

[0014] After the wind blows at the root of blade B, some of the wind enters the middle cavity and acts on the third blade structure, causing the third blade structure to rotate.

[0015] Furthermore, the blade B comprises a root, a middle curved portion, and an end portion that are sequentially connected as a single unit;

[0016] An air inlet is formed between adjacent blades B and between their roots, and an air outlet is formed between the curved sections in the middle.

[0017] After the wind blows at the root of blade B, some of the wind enters the middle cavity through the air inlet, then acts on the third layer of blades, and finally flows out from the air outlet.

[0018] Furthermore, the third blade structure includes multiple arc-shaped blades C, which are curved in an arc shape in the radial direction.

[0019] Furthermore, the third layer of blade structure also includes a sleeve, which is fitted onto the rotating shaft via a keyway;

[0020] The multiple arc-shaped blades C are arranged circumferentially along the cylindrical surface of the sleeve.

[0021] Optionally, it also includes a first blade structure disposed at the end of the second blade structure and sleeved on the rotating shaft; the first blade structure disperses the wind, allowing the dispersed wind to act on the second blade structure.

[0022] Furthermore, the first blade structure includes a cone head and multiple helical blades A;

[0023] Multiple helical blades A are arranged on the conical surface of the cone head; the cone head is sleeved on the rotating shaft;

[0024] A spiral groove is formed between adjacent spiral blades A;

[0025] After the wind acts on the helical blade A, part of the wind is dispersed through the helical groove and guided to the root of the helical blade C.

[0026] Optionally, it also includes a mounting base; the rear end of the said rotating shaft is mounted on the mounting base;

[0027] The rotating shaft is fitted with a dustproof and water-blocking plate and a dustproof and water-blocking groove; the dustproof and water-blocking plate and the dustproof and water-blocking groove are located between the second blade structure and the mounting base.

[0028] Furthermore, the mounting base has multiple deep holes and oil passages; springs are placed inside the deep holes, and the springs abut against the mounting components to form a shock-absorbing structure; the rotating shaft is mounted on the mounting base via bearings; the oil passages lead to the bearings to form a lubrication structure.

[0029] Furthermore, the mounting base is circular or rectangular.

[0030] The present invention has the following advantages:

[0031] By setting up a first blade structure, a second blade structure, and a third blade structure, the wind can be utilized in stages and multiple times to drive the shaft to rotate, thereby improving the utilization rate of wind energy.

[0032] Each time wind energy is utilized, the direction of some wind will change, but the wind after the change in direction can still be fully utilized, further improving the utilization rate of wind energy.

[0033] In addition to driving the shaft to rotate, the first blade structure can also disperse and guide the wind, allowing the wind to act better on the second blade structure.

[0034] In addition to driving the shaft to rotate, the second blade structure also allows wind to smoothly enter the interior and drive the third blade structure to rotate; and the wind that drives the third blade structure to rotate can be smoothly discharged without affecting the second blade structure.

[0035] The overall structure is simple and compact;

[0036] Dustproof and water-proof baffles and dustproof and water-proof channels can prevent dust from entering the mounting base in the wind. Attached Figure Description

[0048] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0049] like Figures 1-3 As shown, the mobile wind turbine head includes a rotating shaft 1, on which a second blade structure 20 is mounted. The second blade structure 20 includes multiple blades B21, which are bent into a hand-operated windmill shape. When the wind blows at the root of the blades B21, it drives the entire second blade structure 20 to rotate.

[0050] In this embodiment, when the second blade structure 20 is unfolded and laid flat, it includes an annular center and blades B21; multiple blades B21 are arranged circumferentially along the annular center, and the annular center has a spline hole; the root 2101 of the blade B21 is connected to the annular center, and its end 2103 is in a free state, with corresponding mounting holes opened on the end.

[0051] When the second blade structure 20 is mounted on the rotating shaft 1 in the shape of a hand-made windmill: the annular center is fitted onto the rotating shaft 1 through the spline hole, and the rotating shaft 1 has a corresponding keyway; the free end of the blade B21 is bent, and after the end is bent, it is inserted onto the rotating shaft 1 through the mounting hole; thus forming a structure similar to a hand-made windmill.

[0052] When leaf B21 bends, it forms a root 2101, a tip 2103, and an intermediate bend 2102 between them.

[0053] In this embodiment, the area of ​​the root 2101 is larger than the areas of the end portion 2103 and the intermediate curved portion 2102. This arrangement prevents the end portion 2103 and the intermediate curved portion 2102 from obstructing the root 2101 when the wind blows. Specifically, when the blade B21 bends, the radial projection of the root 2101 is larger than the radial projection areas of the end portion 2103 and the intermediate curved portion 2102.

[0054] Optionally, the mobile wind turbine head, such as Figure 2 and Figure 4 As shown, it also includes a third blade structure 30.

[0055] Specifically, when the blade B21 is bent into a hand-operated windmill shape, the root 2101 and the end 2103 have a certain distance in the axial direction. With this arrangement, multiple blades B21 can cover and form an intermediate cavity after bending. The third blade structure 30 is set in this intermediate cavity and is sleeved on the rotating shaft 1.

[0056] In this embodiment, the third blade structure 30 includes a sleeve 32 and a plurality of arc-shaped blades C31; the plurality of arc-shaped blades C31 are arranged circumferentially along the outer cylindrical surface of the sleeve 32, and the arc-shaped arrangement of the arc-shaped blades C31 is such that they are curved in the radial direction; the sleeve 32 is sleeved on the rotating shaft 1 through a spline groove structure.

[0057] It should be noted that in the second blade structure 20, an air inlet is formed between the roots of adjacent blades B21, and an air outlet is formed between the curved sections in the middle. When the wind blows on the root of blade B21, some of the wind enters the middle cavity through the air inlet, then acts on the third layer of blades 30, and finally flows out from the air outlet.

[0058] Optionally, the mobile wind turbine head, such as Figure 1 As shown, it also includes a first blade structure 10, which is sleeved on the rotating shaft 1.

[0059] Specifically, the first blade structure 10 includes a cone head 11 and a plurality of helical blades A12. The cone head 11 is sleeved on the rotating shaft 1 and is located at the end 2103 of the second blade structure 10; the plurality of helical blades A12 are arranged circumferentially along the conical surface of the cone head 11.

[0060] In this embodiment, a spiral groove 13 is formed between adjacent spiral blades A12 on the cone head 11. After the wind acts on the spiral blade A12, part of the wind is dispersed and guided to the root of the spiral blade C12 through the spiral groove 13, which can disperse and guide the wind.

[0061] Optionally, the mobile wind turbine head, such as Figure 5 and Figure 6 As shown, it also includes a mounting base 40.

[0062] Specifically, the rear end of the rotating shaft 1 is mounted on the mounting base 40 via a bearing. The mounting base 40 has multiple deep holes 43 and oil passages 44.

[0063] In this embodiment, a spring is placed inside the deep hole 43, and the spring abuts against the mounting component to form a shock-absorbing structure.

[0064] In this embodiment, oil passage 44 leads to the bearing to form a lubrication structure.

[0065] In this embodiment, a dustproof and water-blocking plate 41 and a dustproof and water-blocking groove 42 are sequentially provided on the rotating shaft 1 between the second blade structure 20 and the mounting base 40, along the direction from the front end to the rear end of the rotating shaft 1. This prevents dust from entering the mounting base 40. The dust-blocking groove 42 is directly fixed to the mounting base 40 with screws.

[0066] In this embodiment, the mounting base 40 is circular or rectangular. The mounting base 40 is fixed to a bracket, allowing the entire fan head to be moved, thus creating a movable type.

[0067] It should be noted that in the above embodiments, to prevent water, sand, and other substances from abrading the corresponding blades, a protective layer is provided on the surface of the corresponding blades. The protective layer can be a film layer or a rubber layer. Of course, a protective layer can also be provided on the corresponding dustproof and water-blocking plates 41 and dustproof and water-blocking grooves 42.

[0068] It should be noted that the rotating shaft 1 is a stepped shaft, with a first step, a second step, and a third step sequentially on the rotating shaft 1 from the front end of the rotating shaft 1 to the rotating shaft 1 of the mounting base 40.

[0069] During installation:

[0070] First, insert the dustproof and water-proof plate 41 into the third step of the rotating shaft 1;

[0071] Then the annular center is fitted onto the third step of the rotating shaft 1, and the annular center component presses the dustproof and water-blocking plate 41 against the third step.

[0072] The sleeve 32 in the third blade structure 30 is fitted onto the rotating shaft 1 through splines and spline grooves, and the sleeve 32 abuts against the annular center; since the arc-shaped blade C31 and the sleeve 32 are integrated, the installation of the third blade structure 40 is thus achieved.

[0073] The end 2103 of the blade B21 is bent and then threaded onto the rotating shaft 1. At this time, the end 2103 is located at the second step, so multiple blades B21 form a structure similar to a handmade windmill, thus forming the second blade structure 20.

[0074] Then screw the cone head 11 onto the first step. The cone head 11 will lock the end 2103 of the blade B21 into the second step. Of course, if the end 2103 at the second step is loose, the cone head 11 can be adjusted by inserting a shim on the rotating shaft 1.

[0075] The principle behind the wind-driven rotation of shaft 1 is as follows: First, the wind contacts the helical blade A12 of the first blade structure 1, initially causing shaft 1 to rotate. After contacting the helical blade A12, the wind is divided into multiple parts. These divided winds act along the helical groove 13 on the root 2101 of the blade B21 of the second blade structure 20, again causing shaft 1 to rotate. Then, a portion of the wind acting on the root 2101 enters the intermediate cavity through the air inlet and contacts the arc-shaped blade 31 of the third blade structure 30, ultimately also causing shaft 1 to rotate. In other words, when the wind blows from the front to the rear of shaft 1, its direction changes upon contact with the corresponding blade structure; however, the changed wind continues to act on the next stage of the blade structure, fully utilizing wind energy. When used for power generation, this significantly improves the utilization rate of wind energy.

[0076] The above embodiments only illustrate preferred implementation methods, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the protection scope of this invention.
