Description

Technical Field

[0001] This utility model relates to the field of wind turbine impeller technology, and specifically discloses an adjustable corrosion-resistant fiberglass wind turbine impeller. Background Technology

[0002] Fiberglass fans are fans made of fiberglass materials. Their appearance and dimensions are exactly the same as steel fans. The biggest feature of fiberglass fans is their corrosion resistance, which allows them to operate stably for a long time in harsh environments such as acids and alkalis. The outer shell and impeller of a fiberglass fan are both made of fiberglass. The impeller is the key component in a fiberglass fan that generates airflow rotation. It can rotate at high speed under the drive of a motor, thereby driving the airflow to rotate and forming the effect of suction and exhaust.

[0003] Chinese patent CN208702773U discloses an adjustable fiberglass anti-corrosion fan impeller, including an outer hub, an inner hub, and fan blades. The fan blades are arranged between the outer hub and the inner hub. A fixing frame is fixedly connected to one end of the fan blades near the outer hub. A fixing column is fixedly connected to the top of the fixing frame. The fixing column passes through the outer hub and extends to the other side. The outer ring of the outer hub near the fixing column is movably connected to a limiting rod by a pin. Several fixing holes that cooperate with the limiting rod are evenly spaced on the surface of the fixing column. This adjustable FRP (fiberglass reinforced plastic) corrosion-resistant fan impeller features a sleeve housing a fixing bracket, fixing column, limiting rod, compression spring, fixing hole, connecting column, sleeve, pin, and pin hole, facilitating blade angle adjustment during use. The pin and pin hole also allow for easy blade disassembly and assembly, simplifying maintenance and replacement. However, during use, dust and other impurities easily adhere to the compression spring, increasing cleaning and maintenance costs. Furthermore, the centrifugal force generated by the impeller and blade rotation can cause the compression spring and limiting rod to wobble, affecting the limiting rod's effectiveness in controlling the fixing column and blades, thus impacting impeller stability. Additionally, the limited adjustment of the number of blades in the impeller also affects its practicality. Therefore, to address these issues, this invention proposes an adjustable corrosion-resistant FRP fan impeller. Utility Model Content

[0004] The present invention aims to provide an adjustable, corrosion-resistant fiberglass fan impeller, which facilitates the installation and maintenance of components in the angle adjustment mechanism. It can limit the rotation of the first and second shafts, keeping them stable during the rotation of the fan blades, thus ensuring the stability of the fan blades and impeller. The number of fan blades and the angle adjustment mechanism connected to the fan blades is easy to adjust, enhancing the practicality of the fan impeller.

[0005] This utility model is achieved through the following technical solution:

[0006] An adjustable, corrosion-resistant fiberglass fan impeller includes a support structure comprising a support plate and a support ring. The support ring is located on the outer side of the support plate, and the outer side of the support plate has multiple mounting grooves arranged in a circumferential array. Multiple angle adjustment mechanisms arranged in a circumferential array are provided between the support plate and the support ring. Each angle adjustment mechanism includes a connecting block. One end of the connecting block has a connecting groove, and one side of the connecting groove has a limiting hole through which a screw is inserted. One side of the connecting block has a first rotating shaft, and the first rotating shaft has multiple first connecting holes arranged in a circumferential array. The end of the first rotating shaft away from the connecting block is connected to a fan blade body. The end of the fan blade body away from the first rotating shaft has a second rotating shaft, and the second rotating shaft has multiple second connecting holes arranged in a circumferential array. A support base is located on the outer side of the second rotating shaft, and the support base has a third connecting hole through which a bolt is inserted, passing through the second connecting hole.

[0007] As a further feature of the above solution, a shaft groove is connected to one side of the middle of the support plate to facilitate the connection of the fan impeller to the original power shaft. The connecting block and the mounting groove are detachably connected to facilitate the installation and maintenance of the connecting block.

[0008] As a further feature of the above solution, the mounting slot is detachably connected to a blocking block, which can block the mounting slot that is not connected to the connecting block, so as to keep the inner wall of the mounting slot clean and reduce the workload of the user in cleaning the mounting slot before installing the connecting block.

[0009] As a further feature of the above solution, the first rotating shaft is rotatably connected to the connecting groove, and the screw passes through the inside of the first connecting hole and is threadedly connected to the first connecting hole. After the fan blade body drives the first rotating shaft to rotate a certain angle in the connecting groove, the screw passing through the limiting hole is connected to the first connecting hole aligned with the limiting hole, so as to fix the first rotating shaft and prevent the first rotating shaft from shaking during the rotation of the impeller. The fan blade body and the first rotating shaft are detachably connected, which facilitates the disassembly and assembly of the first rotating shaft and the fan blade body and independent maintenance.

[0010] As a further feature of the above scheme, a limiting plate is provided at the end of the second rotating shaft near the fan blade body. The limiting plate is detachably connected to the fan blade body, which facilitates the installation and maintenance of the limiting plate. The second rotating shaft passes through the interior of the support base and is rotatably connected to the support base. A baffle is detachably connected at the end of the second rotating shaft away from the fan blade body, which can initially limit the position of the second rotating shaft.

[0011] As a further feature of the above scheme, the inner side of the support ring is connected to a plurality of mounting plates arranged in a circumferential array. The support base is detachably connected to the mounting plates, which facilitates the installation and maintenance of the support base and the entire angle adjustment mechanism. A nut is threaded to one end of the bolt, which can further limit the position and angle of the second rotating shaft and the fan blade body.

[0012] The present invention has the following beneficial effects during use:

[0013] The design of multiple mounting slots inside the support plate allows users to flexibly adjust the number of fan blades and angle adjustment mechanisms according to actual needs, improving the practicality of the fan impeller. The removable plugs inside the mounting slots can block the mounting slots that are not connected to the connecting blocks, keeping the inner wall of the mounting slots clean and reducing the amount of work users need to do to clean the mounting slots before installing the connecting blocks.

[0014] The combination of the second shaft, bolt, and nut allows the fan blades to be adjusted to a suitable angle by rotating the second shaft at a certain angle in the support base. Then, a bolt is inserted from one end of the third connecting hole, passes through the second connecting hole aligned with the third connecting hole, and exits from the other end of the third connecting hole. The nut is then screwed onto the outside of the bolt to limit the position and angle of the second shaft and the fan blade body.

[0015] The combination of the first shaft and the screw allows the first shaft to rotate at a certain angle in the connecting groove after the fan blade body drives it. The screw, which passes through the limiting hole, is then connected to the first connecting hole aligned with the limiting hole, so as to fix the first shaft and prevent it from shaking during the impeller rotation.

[0026] like Figure 1 and Figure 3 As shown, the support plate 11 has a shaft groove 12 connected to one side of the middle section, which facilitates the connection of the fan impeller to the original power shaft. The connecting block 21 is detachably connected to the mounting groove 111, which facilitates the installation and maintenance of the connecting block 21.

[0027] like Figure 1 and Figure 3 As shown, the mounting groove 111 is detachably connected to a blocking block 13, which can block the mounting groove 111 that is not connected to the connecting block 21, so as to keep the inner wall of the mounting groove 111 clean and reduce the workload of the user in cleaning the mounting groove 111 before installing the connecting block 21.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the first rotating shaft 22 is rotatably connected to the connecting groove 211. The screw 222 passes through the inside of the first connecting hole 221 and is threadedly connected to the first connecting hole 221. After the fan blade body 3 drives the first rotating shaft 22 to rotate a certain angle in the connecting groove 211, the screw 222 passing through the limiting hole 212 is connected to the first connecting hole 221 aligned with the limiting hole 212, so as to fix the first rotating shaft 22 and prevent the first rotating shaft 22 from shaking during the impeller rotation. The fan blade body 3 and the first rotating shaft 22 are detachably connected, which facilitates the disassembly and assembly of the first rotating shaft 22 and the fan blade body 3 and independent maintenance.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a limiting plate 232 is provided at one end of the second rotating shaft 23 near the fan blade body 3. The limiting plate 232 is detachably connected to the fan blade body 3, which facilitates the installation and maintenance of the limiting plate 232.
