[0002] Impeller refers to both the wheel disk with moving blades, which is a component of the rotor of an impulse steam turbine[1], and the wheel disk and the rotating blades mounted on it. Impellers can be classified according to their shape and opening / closing status.
[0003] Centrifugal impellers are a type of impeller. Existing centrifugal impellers have blades that are connected by welding. In actual operation, the angle of these blades cannot be changed, and they cannot be operated according to specific situations and needs, resulting in a relatively limited function.
[0004] Therefore, we propose a fan impeller and a fan using the impeller. Utility Model Content
[0005] The present invention aims to solve the technical problems existing in the prior art and provides a fan impeller and a fan using the impeller.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a wind turbine impeller, comprising a first fixed disk, a second fixed disk, and a blade assembly.

The positioning frame is rotatably mounted on the upper side wall of the second fixed disk. A drive shaft is fixedly mounted on the upper side wall of the positioning frame. The outer wall of the drive shaft is rotatably mounted on the bottom wall of the first fixed disk through a through-hole. A gear ring is rotatably mounted on the upper side wall of the first fixed disk. The gear ring has an internal tooth groove and an external tooth groove on its outer wall. A first gear is fixedly mounted on the outer wall of the drive shaft. The first gear meshes with the external tooth groove of the gear ring. A transmission rod is rotatably mounted on the upper side wall of the first fixed disk. A detachable second gear is fixedly mounted on the outer wall of the transmission rod. The second gear meshes with the internal tooth groove of the gear ring. A drive mechanism for transmission is provided on the transmission rod.
[0007] Furthermore, an installation housing is fixedly installed on the upper side wall of the first fixed plate. The gear ring, drive shaft, first gear, drive rod and second gear are all located inside the installation housing. The outer wall of the drive rod is rotatably installed on the top wall of the installation housing cavity through a through-hole. A protective housing is fixedly installed on the upper side wall of the installation housing.
[0008] Furthermore, a wireless motor capable of transmission is fixedly installed on the front wall of the protective housing cavity, and a horizontally positioned transmission worm gear is rotatably installed on the rear wall of the protective housing cavity.
[0009] Furthermore, a detachable transmission worm gear is fixedly installed on the outer wall of the transmission rod.

[0013] Beneficial effects
[0014] This utility model provides a fan impeller and a fan using the impeller. It has the following beneficial effects:
[0015] 1. A fan impeller and a fan using the impeller. In use, the drive mechanism causes the transmission rod to rotate in the forward direction, the second gear to start rotating, the gear ring to start rotating in the forward direction with the cooperation of the inner tooth groove, and the first gear to start rotating in the forward direction with the cooperation of the outer tooth groove. In this way, the transmission shaft starts to rotate with the positioning frame, thereby changing the angle of the blade assembly. It can be adjusted according to specific needs to increase the functionality of the device.
[0016] 2. This invention relates to a fan impeller and a fan using the impeller. During use, by turning on the wireless motor, the output end of the wireless motor drives the transmission worm gear to rotate, which in turn drives the transmission worm wheel to rotate the transmission rod. Due to the self-locking effect between the transmission worm gear and the transmission worm wheel, the overall stability can be increased. In addition, the positioning bolt can be rotated forward until the positioning bolt and the blade separate. At this time, the blade can be pulled out from the inside of the positioning frame for replacement or cleaning. The operation is simple and convenient, and easy to use. Attached Figure Description
