Description
Technical Field
[0001] The present invention relates to the technical field of wind turbines, and in particular, to a separable adaptive wind turbine. Background Art
[0002] In the field of wind power generation, separable adaptive wind turbines have received extensive attention in recent years because they can autonomously adjust structural parameters according to wind speed changes, thereby improving the wind energy capture efficiency. Traditional wind turbines usually adopt fixed blades or simple pitch control designs, making it difficult to maintain optimal performance under complex wind conditions. To this end, various adaptive adjustment schemes have been proposed in the prior art, such as dynamically adjusting the blade angle, length, or position through mechanical linkage mechanisms, hydraulic systems, or smart materials.
[0003] For example, the patent document with the publication number CN119933932A in the prior art provides a separable adaptive wind turbine; according to the rotational speed relationship between the lift fan blade and the drag fan blade, the generator adaptively separates or connects the lift rotating shaft and the drag rotating shaft, making full use of the advantages that the drag fan blade is easy to start and the lift fan blade has a high rotational speed, avoiding the situation that the drag fan blade lags behind in rotation at high speeds and affecting the power generation efficiency; according to the relationship between the lift fan blade and the preset upper limit of the rotational speed threshold, when the rotational speed of the lift fan blade is too fast, the protection device connects the lift rotating shaft and the drag rotating shaft together, using the lag of the drag fan blade to reduce the speed of the lift fan blade and avoiding the fan blade rotating too fast and causing equipment damage.
[0004] However, this device still has the following problems: This device arranges structures such as the drag generator, the lift generator, and the protection device in the central fixed shaft of the device and the lift fan blade above it, which undoubtedly increases the center of gravity of the device and reduces the stability of the device. When the external wind force is large, there are significant safety hazards, and the adjustment method of this device is too complex and not convenient for the maintenance of the device.

[0025] The specific working principle and usage method of the present invention will be explained in detail below: When in use, the wind turbine blades 11 are driven to rotate by external wind force; 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 is driven to move outward. Cooperating with the support plate 23, the movable rod 13 can be driven to move upward, so that the second slot 18 and the second insertion rod 181 are separated from each other, the first sun gear 331 and the first sun gear 331 are engaged with each other, the second positioning tooth plate 341 and the positioning tooth groove 34 are inserted into each other, and the positioning tooth cavity 191 and the first positioning tooth plate 19 are inserted into each other. At this time, the high-speed rotating main shaft 12 drives the input shaft 17 to rotate at a reduced speed through the meshing connection between the first planetary gear 33, the first sun gear 331 and the first outer tooth ring 32, so as to achieve the effect of protecting the generator main body 14; When the external wind force returns to the low-speed state, under the action of the spring 22 restoring deformation and cooperating with the support plate 23, the movable rod 13 can be driven to reset downward, so that the first sun gear 331 and the first sun gear 331, the second positioning tooth plate 341 and the positioning tooth groove 34, and the positioning tooth cavity 191 and the first positioning tooth plate 19 are separated from each other, and the second slot 18 and the second insertion rod 181 are re-inserted. At this time, the low-speed rotating main shaft 12 can directly drive the input shaft 17 to rotate with it; Through the insertion connection between the first slot 16 and the first insertion rod 161, during the up and down movement of the movable rod 13, it can always ensure that the movable rod 13 is connected to the main shaft 12, so as to ensure that the main shaft 12 can drive the movable rod 13 to rotate with it.
[0026] Among them, an air inlet hole 4 is opened at the upper end of the base 1, an exhaust hole 41 is opened on the outer wall of the base 1, and filter nets are respectively and fixedly installed in the air inlet hole 4 and the exhaust hole 41; a gas guide hole 46 is opened in the main shaft 12, a second through hole 462 and a first through hole 461 are respectively opened at the upper and lower ends of the gas guide hole 46, and the second through hole 462 and the first through hole 461 are respectively arranged on the upper and lower sides of the air inlet hole 4; a first fan blade 47 is fixedly installed in the gas guide hole 46, a second fan blade 42 is rotatably installed between the outer periphery of the main shaft 12 and the inner wall of the base 1; a limiting ring 43 is fixedly installed in the middle of the air inlet hole 4 through a filter net, a sealing plate 48 is fixedly installed on the outer periphery of the main shaft 12, a second outer tooth ring 44 is fixedly installed inside the second fan blade 42, the second outer tooth ring 44 is rotatably installed between the limiting ring 43 and the sealing plate 48, a second sun gear 49 is fixedly installed on the outer periphery of the main shaft 12, and a second planetary gear 45 meshingly connected with the second sun gear 49 and the second outer tooth ring 44 is rotatably installed on the lower side of the inner cavity of the limiting ring 43 through a bracket.
[0027] During the rotation of the main shaft 12, through the meshing connection between the second planetary gear 45, the second sun gear 49 and the second external gear ring 44, the second fan blade 42 can be driven to rotate therewith. Through the rotating second fan blade 42, in cooperation 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 led out from inside to outside, achieving the effect of dissipating heat from the generator main body 14. A filter screen is provided in the second through hole 462 and the first through hole 461 to block outside dust.
[0028] During the rotation of the main shaft 12, the first fan blade 47 inside the air guide hole 46 can be driven to rotate, and the rotation direction of the second fan blade 42 is opposite to that of the first fan blade 47. In cooperation with the air guide hole 46, the second through hole 462 and the first through hole 461, the air can be redirected to the upper side of the air inlet hole 4 below the air inlet hole 4 and ejected from the upper side of the air inlet hole 4, thereby cleaning the dust on the upper surface of the filter screen at the air inlet hole 4, preventing the filter screen from being blocked, and ensuring the heat dissipation effect of the air on the generator main body 14.
