Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, in particular to a miniaturized wind power generation device. Background Art

[0002] Existing wind power generation devices mainly include horizontal-axis wing-type blade generators and vertical-axis wing-type Darrieus wind turbines. These two types of wind power generation devices are relatively large in size and are mostly installed in remote areas. However, the utilization of wind resources is not limited to large wind power equipment. Miniaturized wind power generation equipment is more suitable for outdoor use.

[0003] Patent No. CN116717429A proposes a miniaturized wind power generation device, including blades, bearings, a rotating rod, a steering device, a wheel shaft, a rotating rod, and a generator. The blades drive the rotating rod through wind power, and drive the generator to generate electricity through the transmission of the rotating rod and the wheel shaft. The blade angle can be adjusted according to the wind force. The bearing seals the inside of the device and also supports the rotating rod. The wheel shaft is used to change the transmission direction. The rotating rod drives the generator to rotate under the action of the wheel shaft, and the steering device adjusts the blades of the generator according to the wind direction.

[0004] When using the existing technology, the fan blades are usually driven directly by the wind to rotate and drive the generator set to generate electricity. However, when the wind is weak, the fan blades rotate slowly, resulting in less electricity generated and unable to meet the usage needs. However, when the wind passes through a narrow and long pipe in a wide area, the wind speed at the pipe mouth will be significantly higher than the wind speed in the wide area.

[0005] Therefore, the present application provides a miniaturized wind power generation device to meet the demand. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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. Example

[0031] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a miniaturized wind power generation device, including a base 1, a turntable 2 is movably mounted on the top of the base 1, an adjustment mechanism 3 is arranged on the top of the turntable 2, a housing 4 is fixedly mounted on the top of the turntable 2, and a power generation mechanism 5 is arranged inside the housing 4;

[0032] like Figure 2 , Figure 3 and Figure 4As shown, the adjustment mechanism 3 includes a first transmission group 31, a second transmission group 32, a positioning block 301, a first servo motor 302 and a first rotating shaft 303. The positioning block 301 is fixedly installed on the top of the turntable 2, the first servo motor 302 is fixedly installed on one side of the positioning block 301, and the first rotating shaft 303 is fixedly installed on the output end of the first servo motor 302. The first transmission group 31 and the second transmission group 32 are symmetrically arranged on the top of the turntable 2 with the first rotating shaft 303 as the center.

[0033] The first transmission group 31 and the second transmission group 32 include a worm 304, a first bearing seat 305, a worm wheel 306, a bidirectional threaded shaft 307, a second bearing seat 308, a threaded block 309, a slider 310, an air guide plate 311 and a slide groove 312. The worm 304 is symmetrically arranged with the first rotating shaft 303 as the center. The first bearing seat 305 is movably installed on one side of the first rotating shaft 303. The top of the worm 304 is meshed with a worm wheel 306. The worm wheel 306 is fixedly sleeved on the middle part of the bidirectional threaded shaft 307.

[0034] The air guide plate 311 is symmetrically arranged with the housing 4 as the center, and the second bearing seat 308 is fixedly installed on the top of the turntable 2.

[0035] The first bearing seat 305 is fixedly installed on the top of the turntable 2 , and the bidirectional threaded shaft 307 is arranged on the top of the first rotating shaft 303 .

[0036] It needs to be further explained that: when it is necessary to adjust the angle of the air guide plate 311 to gather the wind direction on both sides of the shell 4 to the middle of the shell 4, the first servo motor 302 is started to drive the first rotating shaft 303 to rotate, thereby driving the worm 304 on one side of the first rotating shaft 303 to engage with the worm gear 306 for transmission. When the worm gear 306 rotates, the two-way threaded shaft 307 rotates synchronously. At this time, driven by the two-way threaded shaft 307, the thread blocks 309 on both sides of the two-way threaded shaft 307 move toward the middle of the two-way threaded shaft 307 at the same time. At this time, the thread blocks 309 and the slider 310 move inside the slide groove 312 at the same time, further driving the air guide plate 311 to rotate with the left hinge as the axis, thereby controlling the influence range of the air guide plate 311 by changing the angle of the air guide plate 311, and finally achieving the purpose of adjusting the wind force inside the shell 4.

[0037] like Figure 5 , Figure 6 and Figure 7As shown, the power generation mechanism 5 includes a first bracket 501, a second rotating shaft 502, a second bracket 503, a positioning ring 504, a generator set 505, a limiting groove 506, a second servo motor 507, a one-way threaded shaft 508, an internal threaded tube 509 and a rectifier block 510. The first bracket 501 is fixedly installed on one side of the housing 4, the second rotating shaft 502 is movably installed on the inner ring of the first bracket 501, the second rotating shaft 502 is movably installed on one side of the second bracket 503, and the second bracket 503 is fixedly installed on the On the other side of the outer shell 4, a positioning ring 504 is fixedly connected to one side of the second bracket 503, a generator set 505 is fixedly installed on one side of the positioning ring 504, a limiting groove 506 is opened on one side of the second rotating shaft 502, a second servo motor 507 is fixedly installed inside the limiting groove 506, a one-way threaded shaft 508 is fixedly installed on the output end of the second servo motor 507, one side of the one-way threaded shaft 508 is threadedly sleeved with an internal threaded tube 509, and the internal threaded tube 509 is fixedly installed on one side of the rectifier block 510.

[0038] The power generation mechanism 5 also includes a rack 511, a limit block 512, a gear 513, a fan blade 514 and a bearing ring 515. The rack 511 is movably connected to one side of the second rotating shaft 502, one side of the rack 511 is movably connected to the limit block 512, one side of the rack 511 is meshed with a gear 513, the gear 513 is movably installed on one side of the bearing ring 515, and the top of the gear 513 is fixedly connected to the fan blade 514.

[0039] The limiting block 512 is fixedly installed on one side of the second rotating shaft 502 , and the bearing ring 515 is fixedly connected to the inside of a groove opened on the second rotating shaft 502 .

[0040] It needs to be further explained that: when the speed of the second rotating shaft 502 needs to be adjusted, the second servo motor 507 is started to drive the one-way threaded shaft 508 to rotate, and the internal threaded tube 509 moves outward inside the limit groove 506 as the one-way threaded shaft 508 rotates. At this time, the rectifier block 510 drives the rack 511 to move at the same time. In this process, the rack 511 and the gear 513 are engaged and transmitted. At this time, as the gear 513 rotates around the bearing ring 515, when the gear 513 rotates, the fan blades 514 rotate at the same time. By adjusting the angle of the fan blades 514, the contact area between the fan blades 514 and the air is increased or decreased, thereby adjusting the speed of the second rotating shaft 502 to prevent the second rotating shaft 502 from being damaged when the wind is too strong.

[0041] Working principle and use process of the utility model: During the use of the utility model, when a miniaturized wind power generation device is used, first, when it is necessary to adjust the angle of the wind guide plate 311 to gather the wind direction on both sides of the shell 4 to the middle of the shell 4, the first servo motor 302 is started to drive the first rotating shaft 303 to rotate, thereby driving the worm 304 on one side of the first rotating shaft 303 to engage with the worm wheel 306 for transmission. When the worm wheel 306 rotates, the bidirectional threaded shaft 307 rotates synchronously. At this time, driven by the bidirectional threaded shaft 307, the thread blocks 309 on both sides of the bidirectional threaded shaft 307 move toward the middle of the bidirectional threaded shaft 307 at the same time.

[0042] At this time, the threaded block 309 and the slider 310 move simultaneously inside the slide groove 312, further driving the air guide plate 311 to rotate around the left hinge as the axis, thereby controlling the influence range of the air guide plate 311 by changing the angle of the air guide plate 311, and finally achieving the purpose of adjusting the wind force inside the shell 4.

[0043] Next, when it is necessary to adjust the rotation speed of the second rotating shaft 502, the second servo motor 507 is started to drive the one-way threaded shaft 508 to rotate, and the internal threaded tube 509 moves outward inside the limit groove 506 as the one-way threaded shaft 508 rotates. At this time, the rectifier block 510 drives the rack 511 to move at the same time. In this process, the rack 511 is meshed with the gear 513 for transmission, and the gear 513 rotates around the bearing ring 515.

[0044] Finally, when the gear 513 rotates, the fan blade 514 rotates at the same time. By adjusting the angle of the fan blade 514, the contact area between the fan blade 514 and the air is increased or decreased, thereby adjusting the rotation speed of the second rotating shaft 502 to prevent the second rotating shaft 502 from being damaged when the wind force is too strong.

[0045] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
