Description

Technical Field

[0001] This application relates to the technical field of centrifuge wind wheels, and specifically to a new type of centrifuge wind wheel teaching aid. Background Art

[0002] A wind wheel, in electricity and energy, refers to a component of a wind turbine that converts wind energy into mechanical energy. It consists of blades and a hub. A centrifugal wind wheel is a component of a wind turbine that converts wind energy into mechanical energy. The centrifugal wind wheel controls the impeller speed through bearings to control the air volume of the centrifugal fan.

[0003] Patent No. CN221096945U discloses a centrifugal wind wheel. In this centrifugal wind wheel, by setting an impeller, the air flow first does work on the impeller to increase the wind speed and head, and then does work on the centrifugal blades to further increase the wind speed and head until it is thrown out of the centrifugal wind wheel. Without changing the shapes of the original wind wheel's wheel disc, wheel cover, and metal skeleton, the work capacity of the wind wheel is strengthened, the air volume and head of the wind wheel can be greatly increased, and miniaturized design can be achieved, which is suitable for application scenarios with small size and large air volume. However, the impeller and the wheel cover of this wind wheel are integrally designed, and different seasons have different requirements for the functional tendencies of the wind wheel. A single fixed-form impeller is difficult to meet the needs of different seasons. Utility Model Content
