Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation fan technology, specifically a magnetic levitation fan that facilitates pipe connection. Background Technology

[0002] A magnetic levitation fan is a device that uses magnetic levitation technology to drive the rotation of a fan. Compared with traditional fans, magnetic levitation fans do not require physical contact during operation, thus reducing friction and wear, improving efficiency and service life, and reducing noise. The core principle of a magnetic levitation fan is to use a magnetic field to levitate the fan rotor in the air, avoiding contact with the stator or other components. Furthermore, due to the reduction in friction and wear, magnetic levitation fans typically do not require frequent maintenance and component replacement, greatly reducing long-term operating costs and the complexity of maintenance work.

[0003] Magnetic levitation fans use magnetic levitation technology to keep the rotor suspended, avoiding problems such as imbalance and vibration caused by contact. This helps maintain the stability of the fan operation and reduces the impact of mechanical vibration on equipment operation. Magnetic levitation fans mainly deliver gas to the pipeline system through the air outlet. Therefore, the air outlet of the magnetic levitation fan needs to be connected to the ventilation duct to transmit the airflow generated by the fan to downstream equipment or systems. When connecting the fan outlet to the ventilation duct, it is necessary to ensure that the fan and the ventilation duct are fixed and stable. Since the weight of the fan can easily put pressure on the pipeline, if the pipeline is not stably supported, it can easily lead to pipeline displacement or loosening. Therefore, we propose a magnetic levitation fan that facilitates pipeline connection. Utility Model Content

The permanent magnet synchronous motor is installed on the inner side of the fan body, and an air outlet pipe and an air inlet pipe are sequentially installed on the inner side of the fan body near the permanent magnet synchronous motor. The air outlet pipe and the air inlet pipe are respectively connected to the air outlet and air inlet of the permanent magnet synchronous motor. A connecting pipe is connected to one side of the air outlet pipe and one side of the air inlet pipe. The lower side of the connecting pipe is movably connected to a ring plate through a bearing. The lower side of the ring plate is fixed to a handwheel. A connecting plate is provided between the connecting pipe and the ring plate, and one end of the connecting plate is fixed to a support plate. The end of the connecting plate away from the support plate is fixed to a slider.

[0006] Preferably, the slider one has an arc-shaped groove on the side near the ring plate, and the slider one slides into the arc-shaped groove. The support plate has a slider two fixed on the upper side near the slider one.

[0007] Preferably, a straight groove is provided on the side of the connecting pipe near the second slider, the second slider is slidably connected to the straight groove, and the side of the support plate near the connecting pipe is fixed to one end of the fixing plate.

[0008] Preferably, the connecting pipe has a slot on the side near the fixing plate, and the fixing plate is connected to the slot. One side of the fixing plate is movably connected to the gear plate through a bearing.

[0009] Preferably, the toothed disc is in contact with the toothed plate, and the toothed plate is fixed to the slot. A synchronization component is provided on the side of the toothed disc away from the fixed plate, and the synchronization component includes two synchronization pulleys and a synchronization belt.

[0010] Preferably, the synchronizing wheel on one side of the synchronizing component is fixed to one side of the gear plate, and the synchronizing wheel on the other side of the synchronizing component is movably connected to the support plate. The synchronizing wheel of the synchronizing component near the support plate is fixed to the bevel gear.

[0011] Preferably, the first bevel gear and the second bevel gear are connected to each other, and the first bevel gear and the second bevel gear are movably connected to the support plate through bearings, and the upper side of the second bevel gear is fixed to the screw through a shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This magnetic levitation fan, which facilitates pipe connection, fits the ventilation duct and the connecting pipe together. By rotating the handwheel, slider one and slider two drive the support plate closer to the connecting pipe through the connecting plate, causing the support plate to push the fixing plate to align with the slot. This causes the gear plate to rotate along the gear plate. At this time, slider three can drive the clamping plate to move down, so that the support plate moves closer to the connecting pipe while the clamping plate moves down. This allows the support plate and the clamping plate to clamp and limit the ventilation duct at the same time, so that the ventilation duct and the connecting pipe can be stably restricted together, making it easy to install the magnetic levitation fan stably on the ventilation duct.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4This utility model provides a technical solution: a magnetic levitation fan that facilitates pipe connection, comprising a fan body 1 and a permanent magnet synchronous motor 101. The permanent magnet synchronous motor 101 is installed inside the fan body 1, and an air outlet pipe 102 and an air inlet pipe 103 are sequentially installed on the inner side of the fan body 1 near the permanent magnet synchronous motor 101. The air outlet pipe 102 and the air inlet pipe 103 are respectively connected to the air outlet and air inlet of the permanent magnet synchronous motor 101. A connecting pipe 2 is connected to one side of the air outlet pipe 102 and one side of the air inlet pipe 103, respectively. The lower side of the connecting pipe 2 is movably connected to a ring plate 201 via a bearing. The lower side of the ring plate 201 is fixed to a handwheel 2011. A connecting plate 20 is provided between the connecting pipe 2 and the ring plate 201. 2. One end of the connecting plate 202 is fixed to the support plate 203, and the end of the connecting plate 202 away from the support plate 203 is fixed to the slider 1 204. The slider 1 204 has an arc-shaped groove 205 on the side near the ring plate 201, and the slider 1 204 slides into the arc-shaped groove 205. The support plate 203 has a slider 206 fixed on the upper side near the slider 1 204. The connecting pipe 2 has a straight groove 207 on the side near the slider 206, and the slider 206 slides into the straight groove 207. The side of the support plate 203 near the connecting pipe 2 is fixed to one end of the fixing plate 208. The connecting pipe 2 has a slot 209 on the side near the fixing plate 208, and the fixing plate 208 is opposite to the slot 209. One side of 208 is movably connected to the gear plate 210 via a bearing. The gear plate 210 is in contact with the gear plate 211, and the gear plate 211 is fixed to the slot 209. A synchronization component 212 is provided on the side of the gear plate 210 away from the fixed plate 208. The synchronization component 212 includes two synchronization pulleys and a synchronization belt. The synchronization pulley on one side of the synchronization component 212 is fixed to one side of the gear plate 210, and the synchronization pulley on the other side of the synchronization component 212 is movably connected to the support plate 203. The synchronization pulley of the synchronization component 212 near the support plate 203 is fixed to the first bevel gear 213. The first bevel gear 213 is in contact with the second bevel gear 214, and the first bevel gear 213 and the second bevel gear 214 are movably connected to the support plate 203 via bearings. The upper side of bevel gear 214 is fixed to screw 215 via a shaft. The upper end of screw 215 extends through the interior of slider 3 216. A groove 217 is provided on the side of support plate 203 near slider 3 216, and slider 3 216 slides and engages with groove 217. The outer side of slider 3 216 is fixed to clamp plate 218. Slider 1 204 matches arc groove 205, slider 2 206 matches straight groove 207, gear disk 210 meshes with gear plate 211, the timing wheel and timing belt of timing assembly 212 mesh, bevel gear 1 213 meshes with bevel gear 214, screw 215 is threadedly connected to slider 3 216, and slider 3 216 matches with groove 217.

[0021] In specific implementation, according to Figures 1-4The magnetic levitation fan uses magnetic levitation technology to keep the rotor suspended, reducing the impact of mechanical vibration on equipment operation and improving stability. When the air outlet pipe 102 and air inlet pipe 103 of the magnetic levitation fan are connected to the ventilation duct, the ventilation duct is brought into contact with the connecting pipe 2. At this time, rotating the handwheel 2011 causes the ring plate 201 to rotate. The ring plate 201 then causes the arc groove 205 to press against the slider 204, and the slider 206 slides into contact with the straight groove 207, preventing the arc groove 205 from causing the slider 204 to rotate. When the arc-shaped groove 205 presses against the first slider 204, the first slider 204 and the second slider 206 can slide along the arc-shaped groove 205 and the straight groove 207 respectively. By matching the first slider 204 with the arc-shaped groove 205 and the second slider 206 with the straight groove 207, the first slider 204 and the second slider 206 can slide stably along the arc-shaped groove 205 and the straight groove 207. This allows the first slider 204 and the second slider 206 to drive the support plate 203 closer to the connecting pipe 2 via the connecting plate 202, causing the support plate 203 to push the fixing plate 208 to align with the slot 209. The gear disk 210 moves along the gear plate 211. During this time, the gear disk 210 meshes with the gear plate 211, allowing the gear disk 210 to rotate. The gear disk 210 then drives the synchronous pulley on one side of the synchronization assembly 212 to rotate. The synchronous pulley and synchronous belt of the synchronization assembly 212 mesh, allowing the gear disk 210 to drive the first bevel gear 213 to rotate. The first bevel gear 213 meshes with the second bevel gear 214, causing the first bevel gear 213 to drive the second bevel gear 214 to rotate, thereby causing the second bevel gear 214 to drive the screw 21. 5. Rotation is performed, and the slider 216 matches the slide groove 217, so that the slider 216 will not rotate with the screw 215. The screw 215 and the slider 216 are connected by a thread, so that the slider 216 can move down along the screw 215. The slider 216 can drive the clamping plate 218 to move down, so that the support plate 203 moves closer to the connecting pipe 2 while the clamping plate 218 moves down. The support plate 203 and the clamping plate 218 simultaneously clamp and limit the ventilation duct, so that the ventilation duct and the connecting pipe 2 can be stably restrained together, making it easy to install the magnetic levitation fan stably into the ventilation duct.

[0022] In summary, when the air outlet duct 102 and air inlet duct 103 of the magnetic levitation fan are connected to the ventilation duct, the ventilation duct is brought into contact with the connecting pipe 2. The handwheel 2011 is rotated to bring the support plate 203 closer to the connecting pipe 2, causing the support plate 203 to push the fixing plate 208 to align with the slot 209. This causes the gear plate 210 to rotate along the gear plate 211, allowing the slider 216 to move the clamping plate 218 downward. As a result, the support plate 203 moves closer to the connecting pipe 2 while the clamping plate 218 moves downward, allowing the support plate 203 and the clamping plate 218 to simultaneously clamp and limit the ventilation duct, thus stably restricting the ventilation duct and the connecting pipe 2 together. This makes it easy to stably install the magnetic levitation fan into the ventilation duct.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
