Description

Technical Field

[0001] This utility model belongs to the field of wind power equipment technology, specifically, it relates to a new energy axial flow centrifugal fan. Background Technology

[0002] Among existing wind-powered equipment, axial flow fans and centrifugal fans are the two main types. Axial flow fans are characterized by large flow rates and low pressures, making them suitable for applications requiring high-volume ventilation. However, with the rapid development of new energy technologies, how to effectively apply these clean energy sources to wind-powered equipment, improve energy efficiency, and reduce carbon emissions has become a current research hotspot.

[0003] Utility model CN222277026U discloses an air inlet and its dust removal fan, including an air inlet body. The inner cavity of the air inlet body is equipped with a dustproof protective mechanism, which includes a dustproof plate, a baffle curtain, and a connecting rod. The dustproof plate is disposed within the inner cavity of the air inlet body, the baffle curtain is disposed within the inner cavity of the air inlet body and located on the front of the dustproof plate, and the connecting rod is disposed in the middle of the dustproof plate and the baffle curtain. This utility model utilizes a combination of a protective mechanism and a buffer mechanism to achieve a dustproof effect on the air inlet body. When the air inlet is not in use, it prevents external dust and debris from entering the cavity of the air inlet body, thereby avoiding affecting the safety of the internal structure of the dust removal fan. This effectively improves the cleanliness of the air inlet body during use, and also improves the safety of the air inlet and the dust removal fan during use. Furthermore, with the cooperation of the buffer mechanism, the effectiveness and safety of the protective mechanism are enhanced.

[0004] However, the aforementioned patent still has the following problems: particularly regarding the fixing method of the dustproof plate, the original design used a positioning rod snap-fit ​​installation. Although this connection method is simple and easy to implement, with long-term use, the positioning rod may wear or age, leading to a decrease in connection stability, which in turn affects the effectiveness and durability of the dustproof plate. Once the connection between the dustproof plate and the fan body becomes loose, not only will the dustproof effect be greatly reduced, but the dustproof plate may also fall off, causing safety risks and affecting the stability and reliability of the entire fan system. The device structure needs to be improved.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0046] Working principle: The casing 10, as the main body of the fan, is fixedly installed on the ground. An opening is provided inside, and an impeller 24 is rotatably installed in the opening. The impeller 24 is connected to the servo motor 15 through components such as the first fixed ring plate 25 and the second rotating rod 20. When the servo motor 15 is started, it drives the first rotating rod 17 and the second rotating rod 20 to rotate through the coupling, thereby driving the impeller 24 to rotate and generating airflow. The fan is equipped with a dustproof structure, including a first dustproof part and a second dustproof part. The first dustproof part protects the air inlet of the casing 10 from dust through components such as the first dustproof cover plate 31, the telescopic baffle 42, and the first arc-shaped fixed plate 37. By rotating the knob 39, the slider 47 can slide within the groove 38, thereby moving the first arc-shaped moving plate 43 and the telescopic baffle 42 to block the air inlet and adjust the ventilation. The second dustproof part protects the air outlet duct 48 from dust through components such as the second dustproof cover plate 51, the second fixing ring plate 49, and the third limit bolt 53. By rotating the third limiting bolt 53, the second dust cover 51 can be fixed to the top of the second fixing ring plate 49. The bottom of the fan is equipped with a first support base 11 and a second support base 12. The casing 10 is stably supported by components such as the first support base plate 13 and the first support plate 18. Components such as the first limiting ring plate 19 and the sealing ring 54 provide auxiliary sealing for the air outlet, ensuring the fan's sealing performance. The fan is equipped with a new energy power supply system, including a power supply box 14, a servo motor 15, and a solar panel 62. The servo motor 15 is connected to the power supply box 14 via the first wire 16 and is powered by the power supply box 14. The solar panel 62 is connected to the power supply box 14 via components such as the telescopic rod 61 and the hydraulic push rod 59. [The last sentence appears to be incomplete and possibly refers to a different system or mechanism.] The lighting conditions are adjusted up and down to maximize the use of solar energy for auxiliary power supply. When the power generated by the solar panel 62 is sufficient, it can directly charge the power supply box 14 through the second wire 63, reducing dependence on the traditional power grid. When the wind turbine needs to start, the power supply box 14 first provides power to drive the servo motor 15. The servo motor 15 drives the first rotating rod 17 and the second rotating rod 20 to rotate through the coupling, thereby driving the impeller 24 to rotate and generate airflow. At the same time, the first dustproof part and the second dustproof part in the dustproof structure respectively protect the air inlet and the air outlet duct from dust, ensuring the normal operation of the wind turbine and the improvement of air quality. With the support of the new energy power supply system, the wind turbine can operate more environmentally friendly and efficiently, reducing the consumption of traditional energy and carbon emissions.
