[0002] A wind turbine is an electrical device that converts wind energy into electrical energy. The working principle of a wind turbine is mainly to use wind power to drive the windmill blades to rotate, and then increase the rotation speed through a speed increaser to enable the generator to generate electricity.

[0025] In order to solve the problem that dust easily enters the air inlet of the wind turbine, when the wind turbine is running, the blades 4 will be driven to swing by the wind flow, and the blades 4 will drive the rotating head 3 to rotate when swinging, and when the rotating head 3 rotates, it will generate electricity through the generator set 5. When the temperature detector 7 detects that the temperature in the fan box 2 is too high, the hydraulic cylinder 8 will be started to shrink the hydraulic cylinder 8 to one side. When the hydraulic cylinder 8 shrinks, it will drive the push plate 9 to slide in the slide groove. When the push plate 9 slides to one side, it will drive the two sets of sealing plates 10 to move to one side at the same time. When the sealing plate 10 moves to one side, the wind hole will be opened, and then the rotating motor 13 will be started to drive the output shaft to rotate together. When the output shaft rotates, it will drive the first cone on one side. The gear 14 rotates, and when the first bevel gear 14 rotates, it will drive the meshing second bevel gear 15 to rotate, and when the second bevel gear 15 rotates, it will drive the rotating rod 16 and the two sets of fan blades 17 to rotate together. When the upper set of fan blades 17 rotates, it can suck the outside air into the fan box 2 to dissipate heat in the fan box 2, and when the lower set of fan blades 17 rotates, it can blow the hot air in the fan box 2 out through the lower set of wind holes, so as to further cool the fan box 2. By setting a blocking component, when the upper set of fan blades 17 sucks air into the fan box 2, the sucked air can be filtered to prevent larger impurities from entering the fan box 2. By setting a closing component, the chute can be kept closed.

[0026] Reference Figure 6-7 The blocking assembly includes a connecting rod 18, which is fixed to the top of the inner wall of the fan box 2, and a support plate 19 is fixed to the bottom of the connecting rod 18. A first spring 20 is fixed to the top of the support plate 19, and a cover plate 21 is fixed to the top of the first spring 20. A wind groove is opened at the top of the cover plate 21, and a slope is set at the top of the cover plate 21. The bottom of the closing plate 10 is set with an oblique angle, and the cover plate 21 is set between the fan blades 17 and the closing plate 10. The blocking assembly is provided with two groups, and is symmetrically distributed between the two groups of wind holes.

[0027] When the sealing plate 10 is driven away from the wind hole, the first spring 20 will push the cover plate 21 at the top to move upward until the top of the cover plate 21 moves out of the wind hole. When the fan blades 17 draw air into the fan box 2, the air flow will flow into the fan box 2 through the cover plate 21, and the wind groove on the cover plate 21 can filter larger impurities at the top of the fan box 2, and promote the impurities to fall elsewhere through the slope of the top of the cover plate 21. After the temperature drops, the hydraulic cylinder 8 can be started to push the push plate 9 and the two sets of sealing plates 10 to move to one side through the hydraulic cylinder 8. When the sealing plate 10 moves to one side, the bevel at the bottom of the sealing plate 10 cooperates with the slope of the top of the cover plate 21 to promote the sealing plate 10 to push the cover plate 21 downward, so that the cover plate 21 retracts into the wind hole, thereby closing the top of the wind hole through the sealing plate 10, and when the cover plate 21 moves, it can also push away impurities that fall around the wind hole.

[0028] Reference Figure 3-4 The sealing component includes a sealing plate 25, which is slidably arranged on the inner wall of the slide groove. A mounting groove 23 is opened on one side of the slide groove. A second spring 24 is fixedly connected to the inner wall of the mounting groove 23. One end of the sealing plate 25 is fixedly connected to one end of the second spring 24. The side of the sealing plate 25 away from the second spring 24 is arranged on one side of the push plate 9.

[0029] When the sealing plate 10 is set at the top of the air hole, the second spring 24 can push the sealing plate 25 to move to one side, so that one side of the sealing plate 25 is against one side of the push plate 9, thereby closing the inside of the slide groove to prevent impurities from falling into the fan box 2 through the slide groove. When the hydraulic cylinder 8 contracts and drives the push plate 9 to move to one side, the sealing plate 25 will be squeezed, so that the sealing plate 25 squeezes the second spring 24 on one side, so that the sealing plate 25 can be temporarily retracted into the installation groove 23.

[0030] Reference Figure 7 The outer wall of the cover plate 21 is fixedly connected with a mesh cover 22 , the shape of the mesh cover 22 is consistent with the shape of the cover plate 21 , and a plurality of small holes are formed on the top of the mesh cover 22 .

[0031] By arranging the mesh cover 22 on the outer wall of the cover plate 21 , when the wind flow enters the cover plate 21 , the wind flow can be easily filtered through the mesh cover 22 , and smaller impurities can be filtered outside the mesh cover 22 .

[0032] Reference Figure 4 A sealing gasket 26 is fixedly connected to the oblique angle of the bottom of the sealing plate 10. The sealing gasket 26 is made of rubber, and the bottom of the sealing gasket 26 is tightly attached to the top of the air hole.

[0033] By providing a rubber sealing pad 26 at the bottom of the sealing plate 10 , when the sealing plate 10 is attached to the top of the air hole, the sealing pad 26 can be used to maintain the airtightness between the sealing plate 10 and the air hole.

[0034] Reference Figure 1 The bottom of the support column 1 is fixedly connected with an inclined plate 27 , and four groups of the inclined plates 27 are provided and distributed in a circle at the bottom of the support column 1 .

[0035] By arranging four groups of inclined plates 27 at the bottom of the support column 1 , after the support column 1 is installed, the four groups of inclined plates 27 can be used to provide a stable supporting effect for the bottom of the support column 1 .

[0036] Working principle: In order to solve the problem that dust easily enters the air inlet of the wind turbine, when the wind turbine is running, the wind flow will drive the blades 4 to swing, and the blades 4 will drive the rotating head 3 to rotate when swinging, and when the rotating head 3 rotates, it will generate electricity through the generator set 5. When the temperature detector 7 detects that the temperature in the fan box 2 is too high, the hydraulic cylinder 8 will be started to shrink the hydraulic cylinder 8 to one side. When the hydraulic cylinder 8 shrinks, it will drive the push plate 9 to slide in the slide groove. When the push plate 9 slides to one side, it will drive the two sets of sealing plates 10 to move to one side at the same time. When the hydraulic cylinder 8 shrinks and drives the push plate 9 to move to one side, it will squeeze the closed plate 25, so that the closed plate 25 squeezes the second spring 24 on one side, so that the closed plate 25 can be temporarily Retract into the installation groove 23, and the closure in the slide groove can be maintained by the sealing plate 25. When the sealing plate 10 moves to one side, the air hole will be opened, and then the rotating motor 13 is started, so that the rotating motor 13 drives the output shaft to rotate together. When the output shaft rotates, it will drive the first bevel gear 14 on one side to rotate. When the first bevel gear 14 rotates, it will drive the meshing second bevel gear 15 to rotate. When the second bevel gear 15 rotates, it will drive the rotating rod 16 and the two groups of fan blades 17 to rotate together. When the upper group of fan blades 17 rotates, it can suck the outside air into the fan box 2 to dissipate heat in the fan box 2, and when the lower group of fan blades 17 rotates, it can blow the hot air in the fan box 2 out through the lower group of air holes. , so that the temperature inside the fan box 2 can be further reduced. When the sealing plate 10 is driven away from the air hole, the first spring 20 will push the cover plate 21 at the top to move upward until the top of the cover plate 21 moves out of the air hole. When the fan blades 17 draw air into the fan box 2, the air flow will flow into the fan box 2 through the cover plate 21, and the wind slot on the cover plate 21 can filter larger impurities at the top of the fan box 2. By arranging a mesh cover 22 on the cover plate 21, smaller impurities can be filtered, and the slope at the top of the cover plate 21 can cause the impurities to fall elsewhere. After the temperature drops, the hydraulic cylinder 8 can be started to push the push plate 9 and the two sets of sealing plates 10 to move to one side through the hydraulic cylinder 8. When the sealing plate 10 moves to one side, it will pass through the sealing plate 10 The bevel at the bottom cooperates with the slope at the top of the cover plate 21, prompting the sealing plate 10 to push the cover plate 21 downward, so that the cover plate 21 retracts into the air hole, thereby closing the top of the air hole through the sealing plate 10. When the cover plate 21 moves, impurities that have fallen around the air hole can also be pushed away. When the sealing plate 10 moves to the top of the air hole, the second spring 24 can push the sealing plate 25 to one side, so that one side of the sealing plate 25 is against one side of the push plate 9, thereby closing the inside of the slide groove and preventing impurities from falling into the fan box 2 through the slide groove. By arranging a rubber sealing gasket 26 at the bottom of the sealing plate 10, when the sealing plate 10 is attached to the top of the air hole, the sealing gasket 26 can be used to maintain the airtightness between the sealing plate 10 and the air hole.
