Description

Technical Field

[0001] This utility model relates to the field of fan impeller technology, and in particular to a novel plate-type axial flow fan impeller. Background Technology

[0002] Traditional axial flow fan impellers consist of a hub and several blades evenly distributed on the hub. The blades are usually made of pressed steel plates or cast aluminum alloys. However, due to various reasons, such impellers have high air resistance and many vortices in the air duct, resulting in low fan efficiency, high noise, and narrow working area. There is an urgent need to design a plate-type axial flow fan impeller with high efficiency, low noise, and wide working area.

[0003] The prior art (CN210949262U) discloses a novel plate-type axial flow fan impeller, which includes a hub and several blades evenly distributed on the outer circumference of the hub. The blades are in a spatial S-shaped twisted shape, with the axis of the hub as the reference from the blade root to the blade tip. Due to the use of a spatial S-shaped twisted free-form surface, the air flow is smoother, the stress on each section of the blade is more uniform, the additional bending moment generated is smaller, the reliability of the impeller during rotation is improved, and the service life is longer. At the same time, the air resistance generated by the impeller is smaller, the high-performance parameter range is wider, and the product selection is more convenient.

[0004] However, in the above solution, the blade and hub are fixed as one piece. When a single blade is damaged, the entire blade needs to be replaced. It is not possible to disassemble and replace individual blades, which results in waste. Utility Model Content

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-3 ,in, Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is a structural schematic diagram of the entire utility model from another perspective. Figure 3 This is a partial sectional view of the fixed plate, connecting bolts, spring, movable plate and limiting plate of this utility model.

[0019] This utility model provides a novel plate-type axial flow fan impeller, including a hub 101 and an impeller assembly 102. The impeller assembly 102 includes a fixed plate 103, a telescopic component 104, a connecting bolt 105, blades 106, a drive component 107, a mounting component 108, and a limiting ring 118. The drive component 107 includes a fixing member 110, a connecting member 111, and a drive shaft 112. The telescopic component includes a spring 113, a movable plate 114, and a limiting plate 115. The mounting component 108 includes a connecting rod 116 and a rotating shaft 117. The aforementioned solution solves the problem that in existing novel plate-type axial flow fan impellers, the blades 106 and hub 101 are fixed as a single unit, requiring the entire impeller to be replaced when a single blade is damaged, making it impossible to disassemble and replace individual blades 106, thus causing waste.

[0020] In this specific embodiment, the hub 101 has a sliding groove 109 located on one side of the fixing plate 103. The fixing plate 103 is slidably connected to the hub 101 and located on one side of the hub 101. The telescopic member 104 is disposed on one side of the hub 101. The connecting bolt 105 is threadedly connected to the hub 101 and located on one side of the hub 101. The blade 106 is fixedly connected to the fixing plate 103 and located on one side of the fixing plate 103. The driving member 107 is disposed on one side of the hub 101. The blade 106 is fixed to the fixing plate 103. The fixing plate 103 can be accessed by the telescopic members on both sides. The telescopic member 104 is fixed by the connecting bolt 105 through a threaded connection with the hub 101, ensuring that the blade 106 is fixed and cannot move. Then, the drive member 107 is connected to one end of the output device. The mounting member 108 is connected and fixed on the new type of plate axial flow fan. The hub 101 is rotated by one end of the drive member 107, thereby guiding the airflow. The above solution solves the problem that in the existing new type of plate axial flow fan impeller, the blade 106 and the hub 101 are fixed as one piece. When a single blade is damaged, the whole impeller needs to be replaced. It is not possible to disassemble and replace a single blade 106, which causes waste.

[0021] The fixing member 110 is fixedly connected to the hub 101 and located on one side of the hub 101. The connecting member 111 is fixedly connected to the fixing member 110 and located on one side of the fixing member 110. The drive shaft 112 is fixedly connected to the connecting member 111 and located on one side of the connecting member 111. The fixing member 110 cross-connects the connecting member 111 and the hub 101, connecting the output end of the output device to the drive shaft 112. Rotating the drive shaft 112 drives the connecting member 111 to rotate. The connecting member 111 is fixedly connected to the hub 101 through the fixing member 110. The rotation of the connecting member 111 drives the hub 101 to rotate, and the rotation of the hub 101 drives the blades 106 to rotate, thereby achieving the effect of guiding the flow.

[0022] Secondly, the spring 113 is fixedly connected to the fixed plate 103 and located on one side of the fixed plate 103. The movable plate 114 is fixedly connected to the spring 113 and located on one side of the spring 113. The limiting plate 115 is fixedly connected to the movable plate 114 and located on one side of the movable plate 114. The spring 113 pushes the movable plate 114 outward according to its own elasticity. The pushing of the movable plate 114 will slide the limiting plate 115 into the sliding groove 109. Then, the connecting bolt 105 passes through and is threadedly connected to the hub 101 to fix the position of the limiting plate 115. When it is necessary to replace it individually, the connecting bolt 105 needs to be loosened first, and then the movable plate 114 is pushed to remove the entire fixed plate 103. By disassembling the blade 106 individually, the problem of needing to replace the whole unit when a single damage occurs can be effectively prevented.

[0023] Meanwhile, the connecting rod 116 is fixedly connected to the fixing member 110 and located on one side of the fixing member 110. The rotating shaft 117 is rotatably connected to the connecting rod 116 and located on one side of the connecting rod 116. The connecting rod 116 is fixed to the fixing member 110. The connecting rod 116 can rotate on the rotating shaft 117. One end of the rotating shaft 117 is rotatably connected to the connecting rod 116, and the other end is fixedly connected to the new type of plate axial flow fan. When the driving device drives the driving shaft 112, it will drive the hub 101 to rotate and guide the airflow. Through the rotational cooperation of the connecting rod 116 and the rotating shaft 117, the whole unit can be effectively fixed in the installation position of the new type of plate axial flow fan and the airflow can be effectively carried out.

[0024] In addition, the limiting ring 118 is connected to the hub 101 and is located on one side of the hub 101. The limiting ring 118 is installed on both sides of the hub 101 to limit the position of the blade 106 during operation.

[0025] In using this utility model, the blade 106 is fixed on the fixing plate 103. The fixing plate 103 can be restricted by the limiting plates 115 on both sides. The spring 113 pushes the movable plate 114 outward according to its own elasticity. The pushing of the movable plate 114 will cause the limiting plate 115 to slide into the sliding groove 109. Then, after the connecting bolt 105 passes through and is threadedly connected to the hub 101 for fixation, it is ensured that the blade 106 is fixed and cannot move. Then, the output end of the output device is connected to the drive shaft 112. By rotating the drive shaft 112, the connecting member 111 is driven to rotate. The connecting member 111 is fixedly connected to the hub 101 through the fixing member 110. The rotation of the connecting member 111 will... The hub 101 is driven to rotate. The connecting rod 116 is connected to the connecting member 111, and the rotating shaft 117 is connected to the new type of plate axial flow fan. The connecting rod 116 and the rotating shaft 117 are rotatably connected. The connecting member 111 is driven to rotate by the driving device, thereby driving the hub 101 to rotate and guide the airflow. When individual replacement is required, the connecting bolt 105 needs to be loosened first, and then the movable plate 114 is pushed to remove the entire fixed plate 103. The above solution solves the problem that in the existing new type of plate axial flow fan impeller, the blades 106 and hub 101 are fixed as one piece. When a single blade is damaged, the entire blade needs to be replaced, and it is impossible to disassemble and replace a single blade 106, which causes waste.
