Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings for ventilation, dust removal, and cooling; in boilers and industrial furnaces for ventilation and induced draft; in air conditioning equipment and household appliances for cooling and ventilation; in grain drying and conveying; as a wind source for wind tunnels and for inflating and propelling hovercraft, etc.

[0003] Currently, a common problem in practical applications of wind turbines is the relatively cumbersome process of installing and disassembling their internal impellers. Typically, the impeller is quickly connected to the output end of the servo motor via bolts. While this design provides convenience during initial installation, it introduces numerous inconveniences during subsequent maintenance and repair.

[0004] Specifically, when wind turbine maintenance is required, a large number of bolts often need to be removed before the impeller can be taken off the output end of the servo motor. This process is not only time-consuming but also requires a significant amount of manpower. Furthermore, frequent bolt removal and installation can lead to bolt wear or damage, thereby increasing maintenance costs and safety risks. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0024] As shown in Figure 1 - Figure 4 An impeller disassembling fan, which comprises a servo motor 2, a connecting seat 3, a connecting bolt 4 and a filter frame 5. The connecting seat 3 is designed to be installed at the output end of the servo motor 2, and the connecting bolt 4 is uniformly distributed around the connecting seat 3.

[0025] The connecting seat 3 is connected with the disassembling impeller assembly 1 through the connecting bolt 4. The filter frame 5 is specially designed at the opening of the front end of the impeller assembly to realize the function of ventilation and filtration. The arrangement of the filter frame 5 enables the fan to effectively filter impurities in the air during operation, thereby ensuring the cleanliness of the air.

[0026] The detachable impeller assembly 1 is composed of a detachable frame, a detachable cover and a quick-release impeller 15. The front end of the connecting seat 3 is connected with the first detachable frame 11 and the second detachable frame 13 through connecting bolts 4. The first detachable frame 11 and the second detachable frame 13 are provided with mounting blocks 17 at the butt joint, and corresponding mounting blocks 17 are provided with mounting members 18, so that the two detachable frames can be quickly assembled through the cooperation of the mounting blocks 17 and the mounting members 18. The first detachable frame 11 is provided with a first detachable cover 12 in the frame, and the second detachable frame 13 is provided with a second detachable cover 14 in the frame. This design not only ensures the stability of the impeller assembly, but also facilitates maintenance and replacement. In actual disassembly, one of the first detachable frame 11 or the second detachable frame 13 can be removed, and the quick-release impeller 15 inside the detachable frame can be disassembled and repaired.

[0027] The output end of the servo motor 2 is connected with the quick-release impeller 15 through a quick-release member 16. The quick-release member 16 includes a fastening cover and a quick-release bolt, and the quick-release bolt passes through the opening in the center of the fastening cover. A limiting groove is formed on the side wall of the output end of the servo motor 2, and a limiting strip of the quick-release impeller 15 is matched with the limiting groove to ensure the stability of the impeller during operation. The fastening cover covers the limiting connection between the quick-release impeller 15 and the output end of the servo motor 2, and is fixedly connected with the output end of the servo motor 2 through the quick-release bolt, so as to realize quick disassembly and installation.

[0028] The top view of the first detachable frame 11 is designed in a "U" shape, which not only looks beautiful, but also provides sufficient strength and stability. The first detachable cover 12 is located in the middle section of the first detachable frame 11 and is fixedly connected with the first detachable frame 11 by welding. The first detachable frame 11 and the second detachable frame 13 have the same structure design, which ensures the symmetry and beauty of the whole. The second detachable cover 14 has the same structure as the first detachable cover 12, which ensures the consistency of the two detachable covers in function and appearance.

[0029] The mounting block 17 is fixedly connected with the first detachable frame 11 or the second detachable frame 13 by welding. The surface of the mounting block 17 is specially designed with anti-skid gaskets to increase the friction with the mounting member 18, thereby improving the stability of the overall structure.

[0032] Usage: Make sure all the connecting parts (connecting bolts 4, quick-release parts 16, etc.) are properly installed and fastened. Turn on the power supply and start the servo motor 2. When the fan is running, the air is filtered by the filter frame 5 to remove impurities. The filtered air enters the impeller assembly and is pushed by the quick-release impeller 15 to generate airflow. Observe whether the fan is running smoothly and whether there are any abnormal noises or vibrations. Check whether the filter frame 5 needs to be cleaned or replaced.

[0033] Maintenance process: Turn off the fan power supply and make sure the equipment is completely stopped running. Loosen the connecting bolts 4 and remove the filter frame 5 for cleaning or replacement. Loosen the connecting bolts 4 and remove the first disassembly frame 11 or the second disassembly frame 13 respectively. Take out the quick-release impeller 15 for inspection or replacement. Check whether the quick-release bolts are fastened and whether the cover is intact. Confirm whether the limiting strip and the limiting groove are matched to ensure the stability of the impeller operation. Check the structural integrity of the first disassembly frame 11 and the second disassembly frame 13. Confirm whether the installation block 17 and the mounting part 18 are firmly connected. Check whether the sealing strip is intact to ensure that no dust and impurities enter the fan. After cleaning or replacing the necessary parts, reassemble all the parts in reverse order. Make sure all the connecting bolts 4 and quick-release bolts are fastened in place. Reconnect the power supply and start the fan for test run. Confirm that the fan is running smoothly without any abnormal noise or vibration. Record the findings and replaced parts during the maintenance process for future maintenance planning.
