Description

Technical Field

[0001] This utility model relates to the field of wind turbine impeller structure technology, and in particular to a high-efficiency and energy-saving centrifugal fan impeller structure for lithium battery equipment. Background Technology

[0002] With the advocacy of energy conservation, emission reduction, and green energy, more and more high-efficiency and energy-saving equipment is being applied in various fields, especially in industries such as wind power, air conditioning, and ventilation. Centrifugal fans, as an important airflow regulation device, play a crucial role in improving equipment efficiency and saving energy. In traditional centrifugal fan design, the efficiency and stability of the impeller are often affected by multiple factors, such as the fixing method between the impeller and the rotating base, the stability of components during rotation, and the durability of the equipment.

[0003] To improve the working efficiency of the fan impeller and maintain its stability during high-speed operation, the stability of the impeller structure is crucial to prevent loosening and vibration. A reasonable limit structure design and a robust connection method can ensure the stability of the impeller during operation. During long-term operation, the centrifugal fan impeller requires regular cleaning and maintenance.

[0004] Therefore, we propose a high-efficiency and energy-saving centrifugal fan impeller structure for lithium battery equipment. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a high-efficiency and energy-saving centrifugal fan impeller structure for lithium battery equipment.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency and energy-saving centrifugal fan impeller structure for lithium battery equipment, including a mounting frame, mounting plates on the left and right sides of the mounting frame, a connecting frame on the front side of the mounting frame, a circular groove at the center of the rear side of the mounting frame, a rotating shaft rotatably mounted in the circular groove, and a drive motor for driving the rotating shaft to rotate is also mounted on the back of the mounting frame; the drive motor is fixed by a limiting seat on the back of the mounting frame.

[0007] The mounting bracket also has a rotating seat rotatably connected inside. The front end of the rotating shaft is connected to the rotating seat. The outer circumference of the rotating seat has several square slots arranged in a ring array. Any square slot has a movable plate for clamping on its side wall. Impellers are engaged between the movable plates of the square slots.

[0008] This utility model has the following beneficial effects: During use, when installing each set of impellers, the elasticity of each set of return springs causes the return springs to contract, driving the moving plate and the limiting rod to contract. The return springs apply force to the moving plate, allowing the limiting rod to extend into the limiting hole, thus installing the impeller in the square groove on the surface of the rotating seat. When it is necessary to disassemble the impeller, pressing the moving plates on both sides again moves the limiting rod away from the limiting hole, facilitating quick disassembly. The cooperation between the limiting ring and the limiting groove limits the rotation shaft, preventing it from disengaging from the circular groove during rotation. The drive motor drives the rotation shaft and the rotating seat to rotate, and the rotation of the rotating seat drives each set of impellers to rotate. The connecting frame protects the impellers.
