Description

Technical Field

[0001] This utility model relates to the field of axial flow fan technology, specifically an axial flow fan with adjustable airflow direction. Background Technology

[0002] Axial flow fans are a type of ventilation equipment widely used in industrial and civil fields. Their working principle is that the rotation of the impeller causes the gas to enter the impeller axially from the air inlet. The gas is pushed by the blades and its energy is increased. Then it flows into the guide vanes, which change the direction of the deflected airflow to axial flow. At the same time, the gas is guided into the diffuser, where the kinetic energy of the gas is further converted into pressure energy. Finally, the gas is introduced into the working pipeline. An adjustable airflow axial flow fan is a type of fan that can adjust the angle of the fan blades. The blade tilt angle can be adjusted as needed to achieve different air volume and air pressure requirements.

[0003] As disclosed in Chinese Patent CN216842384U, an axial flow fan with adjustable airflow direction is provided. By setting up a wind direction changing plate and a connecting plate, and using the action of rotating column one and rotating column two, the wind direction changing plate is driven to rotate, thereby changing the wind direction of the axial flow fan body. With the action of the connecting plate and the rotating shaft, multiple wind direction changing plates can rotate synchronously, which brings great convenience to the industrial work process.

[0004] While this structure allows for adjustment of the airflow direction of the axial flow fan, the axial flow fan can only adjust the lateral airflow. Therefore, we propose an adjustable axial flow fan that can adjust the airflow direction both laterally and longitudinally, allowing for flexible use of the axial flow fan. Utility Model Content

[0005] The purpose of this invention is to provide an axial flow fan with adjustable airflow direction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an axial flow fan with adjustable airflow direction, comprising an axial flow fan body, a protective cover fixedly installed on the inner wall of the axial flow fan body, an assembly plate fixedly installed at the end of the axial flow fan body, and a processing component disposed on the side of the axial flow fan body away from the assembly plate, the processing component including a rotating component disposed on the side of the axial flow fan body away from the assembly plate, and an adjusting component disposed on the side of the rotating component away from the axial flow fan body.

[0007] Preferably, the rotating assembly includes a bracket fixedly installed on the outer wall of the axial flow fan body, a first motor fixedly installed on the outer wall of the bracket, a rotating rod fixedly installed at the output end of the first motor, a first gear fixedly installed at the end of the rotating rod, a support plate rotatably connected to the outer wall of the rotating rod, a groove is opened at the end of the axial flow fan body away from the assembly plate, a limit ring is rotatably connected inside the groove, a rotating ring is fixedly installed on the side wall of the limit ring, and a gear ring is sleeved on the outer wall of the rotating ring.

[0008] Preferably, the adjustment assembly includes a ring body fixedly installed at the end of the rotating ring away from the limiting ring. A mounting plate is fixedly installed on the outer wall of the ring body. A second motor is fixedly installed on the outer wall of the mounting plate. A rotating column is fixedly installed at the output end of the second motor. A guide plate is fixedly installed at the end of the rotating column. A connecting rod is fixedly installed at the end of the guide plate. A second gear is sleeved on the outer wall of the connecting rod. A rack meshes with the outer wall of the second gear.

[0009] Preferably, the outer wall of the rotating ring is rotatably connected to the inside of the groove, and the cross-section of the groove is T-shaped. Under the restriction of the limiting ring, the rotating ring can be prevented from falling off the groove.

[0010] Preferably, the first gear meshes with the gear ring, and the bottom of the support plate is fixedly installed on the outer wall of the axial flow fan body. With the support of the support plate, the first gear stably drives the gear ring to rotate.

[0011] Preferably, the ring body and the rotating ring are fixedly installed at the end away from the limiting ring, and the outer wall of the rack is slidably disposed with respect to the inside of the ring body. Under its restriction, the rotating ring can drive the ring body to rotate, thereby adjusting the direction of airflow. The rotating second gear can drive the rack to slide inside the ring body.

[0012] Preferably, the second gear is fixedly sleeved on the outer wall of the connecting rod, and a groove is opened on the outer wall of the ring. Under the restriction of the groove opened on the outer wall of the ring, the rotating connecting rod drives the rack to move through the second gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This adjustable axial flow fan consists of a rotating assembly. When the airflow direction of the axial flow fan body needs to be adjusted, it is adjusted through the adjusting assembly. When the airflow direction needs to be adjusted longitudinally, the first motor is started, and the rotating rod fixedly installed at its output end rotates accordingly. The first gear fixedly installed at the end of the rotating rod also rotates. Since the limiting ring fixedly installed at the end of the rotating ring is rotatably connected to the inside of the ring groove, and the gear ring meshes with the first gear, under its restriction, the rotating first gear drives the gear ring to rotate accordingly, causing the rotating gear ring to drive the rotating ring to rotate. The rotating ring drives the adjusting assembly fixedly installed on the side away from the limiting ring to rotate as a whole, thus adjusting the airflow direction as a whole to achieve the effect of longitudinal airflow adjustment. With the support of the support plate, the rotating rod stably drives the first gear to rotate. This structure can flexibly adjust the airflow direction of the axial flow fan body, achieving both lateral and longitudinal adjustment effects.

[0015] 2. This adjustable axial flow fan consists of an adjustment assembly. When the airflow direction of the axial flow fan body needs to be adjusted, the second motor is started, and the rotating column fixedly installed at its output end rotates accordingly. The rotating column drives the guide plate to rotate, and the connecting rod fixedly installed at the end of the guide plate drives the second gear to rotate. Since the second gear meshes with the rack and pinion, and the rack and pinion are slidably arranged inside the ring body, under its constraint, the moving rack drives the other guide plates to rotate, thereby adjusting the airflow direction of the axial flow fan body. This structure can adjust the guide plates simultaneously, and the operation is simple. Attached Figure Description

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the adjustable airflow axial flow fan provided by this utility model is as follows: Figures 1 to 6 As shown: An axial flow fan with adjustable airflow direction includes an axial flow fan body 1;

[0025] A protective cover 2 is fixedly installed on the inner wall of the axial flow fan body 1;

[0026] An assembly plate 3 is fixedly installed at one end of the axial flow fan body 1;

[0027] The axial flow fan body 1 is provided with a processing component 4 located on the side away from the assembly plate 3. The processing component 4 includes a rotating component 41 located on the side away from the assembly plate 3 of the axial flow fan body 1. The rotating component 41 includes a bracket 411 fixedly installed on the outer wall of the axial flow fan body 1. A first motor 412 is fixedly installed on the outer wall of the bracket 411. A rotating rod 413 is fixedly installed at the output end of the first motor 412. A first gear 414 is fixedly installed at the end of the rotating rod 413. A support plate 415 is rotatably connected to the outer wall of the rotating rod 413. A groove 416 is provided at the end of the axial flow fan body 1 away from the assembly plate 3. A limit ring 417 is rotatably connected inside the groove 416. A rotating ring 418 is fixedly installed on the side wall of the limit ring 417. A gear ring 419 is sleeved on the outer wall of the rotating ring 418.

[0028] In this embodiment, when the airflow direction of the axial flow fan body 1 needs to be adjusted, it is adjusted by the adjustment component 42. When the airflow direction needs to be adjusted longitudinally, the first motor 412 is started, and the rotating rod 413 fixedly installed at its output end rotates accordingly. The first gear 414 fixedly installed at the end of the rotating rod 413 rotates accordingly. Since the limiting ring 417 fixedly installed at the end of the rotating ring 418 is rotatably connected to the inside of the ring groove 416, and the gear ring 419 meshes with the first gear 414, under its restriction, the rotating first gear 414 drives the gear ring 419 to rotate accordingly, so that the rotating gear ring 419 drives the rotating ring 418 to rotate accordingly. The rotating ring 418 drives the adjustment component 42 fixedly installed on the side away from the limiting ring 417 to rotate as a whole, thereby adjusting the airflow direction as a whole to achieve the effect of longitudinal airflow adjustment. With the support of the support plate 415, the rotating rod 413 stably drives the first gear 414 to rotate. This structure can flexibly adjust the airflow direction of the axial flow fan body 1 and achieve the effect of lateral and longitudinal adjustment.

[0029] Furthermore, the outer wall of the rotating ring 418 is rotatably connected to the inside of the groove 416. The groove 416 has a T-shaped cross section. Under the restriction of the limiting ring 417, the rotating ring 418 can be prevented from falling off the groove 416.

[0030] Furthermore, the first gear 414 meshes with the gear ring 419, and the bottom of the support plate 415 is fixedly installed on the outer wall of the axial flow fan body 1. Under the support of the support plate 415, the first gear 414 stably drives the gear ring 419 to rotate.

[0031] Example 2: Based on Example 1, a preferred embodiment of the adjustable airflow axial flow fan provided by this utility model is as follows: Figures 1 to 6 As shown: The adjustment assembly 42 includes a ring body 428 fixedly installed at the end of the rotating ring 418 away from the limiting ring 417. A mounting plate 421 is fixedly installed on the outer wall of the ring body 428. A second motor 422 is fixedly installed on the outer wall of the mounting plate 421. A rotating column 423 is fixedly installed at the output end of the second motor 422. A guide plate 424 is fixedly installed at the end of the rotating column 423. A connecting rod 425 is fixedly installed at the end of the guide plate 424. A second gear 426 is sleeved on the outer wall of the connecting rod 425. A rack 427 meshes with the outer wall of the second gear 426.

[0032] In this embodiment, when it is necessary to adjust the airflow direction of the axial flow fan body 1, the second motor 422 is started, and the rotating column 423 fixedly installed at its output end rotates accordingly. The rotating column 423 drives the guide plate 424 to rotate accordingly. The connecting rod 425 fixedly installed at the end of the guide plate 424 drives the second gear 426 to rotate. Since the second gear 426 meshes with the rack 427 and the rack 427 is slidably arranged inside the ring body 428, under its constraint, the moving rack 427 drives the other guide plates 424 to rotate, so as to adjust the airflow direction of the axial flow fan body 1. This structure can adjust the guide plates 424 synchronously, and the operation is simple.

[0033] Furthermore, the ring 428 and the rotating ring 418 are fixedly installed at the end away from the limiting ring 417. The outer wall of the rack 427 is slidably set inside the ring 428. Under its restriction, the rotating ring 418 can drive the ring 428 to rotate, thereby adjusting the airflow direction. The rotating second gear 426 can drive the rack 427 to slide inside the ring 428.

[0034] In addition, the second gear 426 is fixedly sleeved on the outer wall of the connecting rod 425, and the outer wall of the ring 428 is provided with a groove. Under the restriction of the groove provided on the outer wall of the rack 427 and the ring 428, the rotating connecting rod 425 drives the rack 427 to move through the second gear 426.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above.
