Description

Technical Field

[0001] This invention relates to the field of wind turbine technology, and more particularly to a split-type adaptive wind turbine. Background Technology

[0002] In the field of wind power generation, split-type adaptive wind turbines have received widespread attention in recent years because they can autonomously adjust their structural parameters according to changes in wind speed, thereby improving wind energy capture efficiency. Traditional wind turbines typically employ fixed blades or simple variable pitch designs, making it difficult to maintain optimal performance under complex wind conditions. To address this, existing technologies have proposed various adaptive adjustment schemes, such as using mechanical linkages, hydraulic systems, or smart materials to dynamically adjust the blade angle, length, or position.

[0003] For example, patent document CN119933932A in the prior art provides a separate adaptive wind turbine generator; the device adaptively separates or connects the lift shaft and the resistance shaft according to the rotational speed relationship between the lift blades and the resistance blades, making full use of the advantages of the resistance blades being easy to start and the lift blades rotating fast, avoiding the resistance blades from rotating lagging at high speeds, which would affect the power generation efficiency; according to the relationship between the lift blades and the preset speed threshold upper limit, when the lift blades rotate too fast, the protection device connects the lift shaft and the resistance shaft together, using the lag of the resistance blades to reduce the speed of the lift blades, avoiding excessive blade rotation and equipment damage.

[0004] However, the device still has the following problems: The device places the drag generator, lift generator and protection devices in the fixed shaft in the middle of the device and the lift fan blades on the upper side. This undoubtedly raises the center of gravity of the device and reduces its stability. When the external wind force is strong, there is a great safety hazard. In addition, the adjustment method of the device is too complicated and it is not convenient for the device to be maintained. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art, and to propose a split adaptive wind turbine.

The first planetary gear is rotatably connected to the limiting rotating seat.

[0010] In the aforementioned type of split adaptive wind turbine, an air inlet is provided at the upper end of the base, and an exhaust port is provided on the outer wall of the base. Filter screens are fixedly installed in both the air inlet and the exhaust port.

[0011] In the aforementioned type of split adaptive wind turbine, an air guide hole is provided inside the main shaft, and a second through hole and a first through hole are respectively provided at the upper and lower ends of the air guide hole.

[0036] The lower end of the spindle 12 is provided with a first slot 16, and the upper end of the movable rod 13 is fixedly installed with a first plug rod 161 that is inserted and connected to the first slot 16. The upper end of the input shaft 17 is provided with a second slot 18, and the lower end of the movable rod 13 is fixedly installed with a second plug rod 181 that is inserted and connected to the second slot 18.

[0037] The lower end of the spindle 12 is provided with a first slot 16, and the upper end of the movable rod 13 is fixedly installed with a first plug rod 161 that is inserted and connected to the first slot 16. The upper end of the input shaft 17 is provided with a second slot 18, and the lower end of the movable rod 13 is fixedly installed with a second plug rod 181 that is inserted and connected to the second slot 18.

[0038] An annular limiting seat 3 is fixedly installed on the inner wall of the base 1. The first external gear ring 32 is rotatably installed in the annular limiting seat 3, and a limiting rotating seat 31 is fixedly installed on the inner wall of the annular limiting seat 3. The first planetary gear 33 is rotatably connected to the limiting rotating seat 31.

[0039] The working principle and usage of this invention are explained in detail below: In use, the wind turbine blades 11 are rotated by external wind power;

[0040] When the external wind force is too strong, the high-speed rotating wind turbine blades 11 drive the slide rail 2 to rotate through the main shaft 12. Through centrifugal force, the movable block 21 moves outward. In conjunction with the support plate 23, the movable rod 13 can move upward, causing the second slot 18 and the second insertion rod 181 to separate from each other, causing the first sun gear 331 to mesh with each other, causing the second positioning tooth plate 341 to insert with the positioning tooth groove 34, and causing the positioning tooth cavity 191 to insert with the first positioning tooth plate 19. At this time, the high-speed rotating main shaft 12 drives the input shaft 17 to decelerate and rotate through the meshing connection between the first planetary gear 33, the first sun gear 331, and the first external gear ring 32, thereby achieving the effect of protecting the generator body 14.

[0041] When the external wind force returns to a low speed, the spring 22 recovers its deformation and, in conjunction with the support plate 23, drives the movable rod 13 to return to its original position. This causes the first sun gear 331 to separate from the first sun gear 331, the second positioning tooth plate 341 to the positioning tooth groove 34, and the positioning tooth cavity 191 to separate from the first positioning tooth plate 19. This also allows the second slot 18 to reconnect with the second insertion rod 181. At this time, the low-speed rotating main shaft 12 can directly drive the input shaft 17 to rotate with it.

[0042] Through the insertion connection between the first slot 16 and the first insert rod 161, the movable rod 13 can always be connected to the main shaft 12 during the up and down movement of the movable rod 13, thereby ensuring that the main shaft 12 can drive the movable rod 13 to rotate with it.

[0043] The base 1 has an air inlet 4 at its upper end and an exhaust 41 on its outer wall. Filters are fixedly installed in both the air inlet 4 and the exhaust 41. The main shaft 12 has an air guide hole 46, with a second through hole 462 and a first through hole 461 at its upper and lower ends, respectively. A first fan blade 47 is fixedly installed within the air guide hole 46 and is rotatably mounted between the outer periphery of the main shaft 12 and the inner wall of the base 1. There is a second fan blade 42; a limit ring 43 is fixedly installed in the middle of the air inlet 4 through a filter screen; a sealing plate 48 is fixedly installed on the outer side of the main shaft 12; a second external gear ring 44 is fixedly installed inside the second fan blade 42; the second external gear ring 44 is rotatably installed between the limit ring 43 and the sealing plate 48; a second sun gear 49 is fixedly installed on the outer side of the main shaft 12; a second planetary gear 45 is rotatably installed on the lower side of the inner cavity of the limit ring 43 through a bracket, which meshes with the second sun gear 49 and the second external gear ring 44.

[0044] During the rotation of the main shaft 12, the meshing connection between the second planetary gear 45, the second sun gear 49, and the second external gear ring 44 drives the second fan blade 42 to rotate. Through the rotating second fan blade 42, in conjunction with the second through hole 462 and the first through hole 461, the outside air can be guided from top to bottom into the base 1, and the air inside the base 1 can be drawn out from the inside to the outside, thereby achieving the effect of heat dissipation for the generator body 14. Filter screens are installed in the second through hole 462 and the first through hole 461 to block external dust.

[0045] During the rotation of the main shaft 12, the first fan blade 47 inside the air guide hole 46 can be rotated, and the second fan blade 42 rotates in the opposite direction to the first fan blade 47. In conjunction with the air guide hole 46, the second through hole 462, and the first through hole 461, air can be redirected from the lower side of the air intake hole 4 to the upper side of the air intake hole 4, and the air can be ejected from the upper side of the air intake hole 4. This can clean the dust on the surface of the filter screen at the air intake hole 4, prevent the filter screen from becoming clogged, and ensure the heat dissipation effect of the air on the generator body 14.

[0046] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
