Description

Technical Field

[0001] This utility model relates to the field of fan impeller technology, specifically an angle-adjustable high-temperature fan impeller. Background Technology

[0002] The impeller is the core component of a fan. Its main functions include fanning air, increasing airflow, increasing wind speed, regulating airflow direction, and reducing temperature. The impeller angle has a significant impact on air volume. When the blade angle is increased to a suitable angle, the air volume will also increase because increasing the blade angle can promote airflow through the impeller, thereby increasing the exhaust volume.

[0003] Application number CN202022092884.1 discloses an adjustable-angle wind turbine impeller, including a mounting base and blades. The main body of the mounting base is disc-shaped, and there are four blades symmetrically mounted on the outer ring of the mounting base. The mounting base is a split structure, mainly composed of an upper base and a lower base. A mounting head is provided on the inner end of the blade, and the blades are evenly mounted between the upper and lower bases through the mounting head.

[0004] The aforementioned patented structure requires disassembling structural components in different locations to adjust the impeller angle, which is a rather cumbersome process and makes it inconvenient to quickly adjust the impeller angle, thus making it less convenient to use. Utility Model Content

A cover is fixed to the base with bolts, and a drive shaft is provided on the cover. An impeller is provided on the base, and an adjustment structure for adjusting the impeller angle is provided inside the base.

[0009] The adjustment structure includes a cavity located inside a base. An adapter sleeve is fixed inside the cavity, and a linkage shaft is rotatably connected inside the adapter sleeve. A mounting plate is fixed to one inner end of the linkage shaft, and a driven gear plate is bolted to the mounting plate. A driven shaft is fixed to the output end of the adjustment motor, and a planetary carrier is fixed to the driven shaft. A drive gear ring is fixed to the planetary carrier.

[0010] Preferably, the adapter sleeve is fixed on the inner wall of the machine cavity, and the driven gear plate is rotatably connected to the adapter sleeve through the driven shaft.

[0011] Preferably, the driven gear disk is arranged along the circumferential direction of the driving gear ring, and the driven gear disk meshes with the driving gear ring.

[0012] Preferably, the machine head and the machine cover are located on both sides of the machine base, and the drive shaft is fixedly connected to the machine cover.

[0013] Preferably, there is a gap between the impeller and the base, the linkage shaft passes through the base and is rotatably connected to the base, and the impeller is fixed on the linkage shaft.

[0014] Preferably, the bearing ring is adapted to the transition groove.

[0015] Preferably, a gap is left between the two sets of adjacent impellers.

[0016] Preferably, the internal structure of the head unit contains a small battery and a controller.

[0017] Compared with the prior art, this utility model provides an angle-adjustable high-temperature fan impeller, which has the following beneficial effects:

[0018] 1. When the angle of this adjustable high-temperature fan impeller needs to be adjusted, the drive gear ring meshes with the driven gear disc, which in turn drives the linkage shaft to rotate. The linkage shaft then drives the impeller to rotate and adjusts the impeller angle, thus enabling the impeller angle to be adjusted quickly and automatically.

[0019] 2. The adjustable-angle high-temperature fan impeller allows for more precise control and adjustment of the impeller's rotation angle by adjusting the motor. Furthermore, the impeller's rotation angle can be adjusted without disassembling the equipment, making the adjustment more convenient and allowing the high-temperature fan to be put into use more quickly.

[0027] Please see Figure 1-5This utility model provides an angle-adjustable high-temperature fan impeller, including a cover 1 and a base 2. An outer support 3 is fixed inside the cover 1. A bearing ring 4 is fixed to one end of the inner side of the outer support 3. The outer support 3 is rotatably connected to the head 5 through the bearing ring 4. A transition groove 6 is opened on the surface of the head 5. An adjustment motor 7 is fixed inside the head 5. An cover 8 is fixed to the base 2 by bolts. A drive shaft 9 is provided on the cover 8. An impeller 10 is provided on the base 2. An adjustment structure for adjusting the angle of the impeller 10 is provided inside the base 2.

[0028] The adjustment structure includes a cavity 11, which is located inside the base 2. An adapter sleeve 12 is fixed inside the cavity 11. A linkage shaft 13 is rotatably connected inside the adapter sleeve 12. A mounting plate 14 is fixed to one end of the inner side of the linkage shaft 13. A driven gear 15 is fixed to the mounting plate 14 by bolts. A driven shaft 16 is fixed to the output end of the adjustment motor 7. A planetary carrier 17 is fixed to the driven shaft 16. A drive gear ring 18 is fixed to the planetary carrier 17. By fixing the cover 1 to the external frame and by fixing the drive shaft 9 to the output end of the external motor, starting the external motor can drive the drive shaft 9 to rotate. In turn, the drive shaft 9 can drive the base 2 to rotate. The base 2 can then drive the impeller 10 to rotate and operate.

[0029] Furthermore, the adapter sleeve 12 is fixed on the inner wall of the machine cavity 11, and the driven gear disk 15 is rotatably connected to the adapter sleeve 12 through the driven shaft 16, so that the driven shaft 16 can be supported and rotated through the adapter sleeve 12.

[0030] Furthermore, the driven gear 15 is arranged along the circumferential direction of the drive gear ring 18, and the driven gear 15 meshes with the drive gear ring 18, so that the drive gear ring 18 can drive the driven gear 15 at different positions to rotate simultaneously when it rotates through the meshing of the driven gear 15 and the drive gear ring 18.

[0031] Furthermore, the machine head 5 and the machine cover 8 are located on both sides of the machine base 2. The drive shaft 9 is fixedly connected to the machine cover 8, and the machine head 5 is fixedly connected to the machine base 2. The drive shaft 9 can drive the machine base 2 to rotate through the machine cover 8. When the machine base 2 rotates, the machine head 5 also rotates.

[0032] Furthermore, there is a gap between the impeller 10 and the base 2. The linkage shaft 13 passes through the base 2 and is rotatably connected to the base 2. The impeller 10 is fixed on the linkage shaft 13 to avoid interference between the impeller 10 and the base 2 when rotating. The linkage shaft 13 can drive the impeller 10 to rotate.

[0033] Furthermore, the bearing ring 4 is adapted to the transition groove 6, which facilitates the rotation of the machine head 5 through the outer bracket 3 and the bearing ring 4.

[0034] Furthermore, a gap is left between the two sets of adjacent impellers 10 to avoid interference between the two sets of adjacent impellers 10 during rotation.

[0035] Furthermore, the machine head 5 is equipped with a small battery and controller, which allows the small battery to power the regulating motor 7 and the controller, and the controller to precisely control the regulating motor 7.

[0036] In use, by fixing the casing 1 to the external frame and the drive shaft 9 to the output end of the external motor, starting the external motor can drive the drive shaft 9 to rotate, which in turn drives the base 2 to rotate. The base 2 can then drive the impeller 10 to rotate. When it is necessary to adjust the angle of the impeller 10, starting the adjustment motor 7 located inside the head 5 can drive the driven shaft 16 to rotate. The driven shaft 16, through the planetary carrier 17, can drive the drive gear ring 18 to rotate. The drive gear ring 18, through meshing with the driven gear disc 15, can cause the driven gear disc 15 to drive the linkage shaft 13 to rotate. The linkage shaft 13 can then drive the impeller 10 to rotate and adjust the angle of the impeller 10. This allows for quick and automatic adjustment of the impeller 10 angle, making the adjustment of the impeller 10 of the high-temperature fan more efficient and convenient, so that the high-temperature fan can be put into use quickly.
