[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. The outer walls of the circular mounting shaft A and the circular mounting shaft B of the present invention are provided with limiting grooves, which limit a row of silicon steel sheets in two directions, avoiding the rotation of a row of silicon steel sheets and also avoiding the left and right sliding of a row of silicon steel sheets; the setting of the two connecting spheres A makes the insertion connection between the circular mounting shaft A and the circular mounting shaft B more stable;
[0019] In addition, the setting of the two connecting spheres B plays a limiting role on the cooling fan, making the insertion connection between the cooling fan and the circular mounting shaft B more stable; the circular mounting shaft A and the circular mounting shaft B can be separated only after being stressed, and the cooling fan and the circular mounting shaft B can also be separated only after being stressed.
[0020] 2. When the circular mounting shaft B rotates in the present invention, the solid inertial block can rotate simultaneously with the circular mounting shaft B, and under the action of inertia, the solid inertial block can automatically move outward by a certain distance. When the solid inertial block drives the movable extrusion frame to move outward, the movable extrusion frame squeezes the circular movable rod A and the circular movable rod B to move, so that the outer ends of the circular movable rod A and the circular movable rod B are inserted into the two helical springs A. At this time, the two helical springs A do not have elasticity, ensuring that the two connecting spheres A will not separate from the circular mounting shaft A, and also ensuring that the connecting sphere B will not separate from the radiator fan, increasing the stability during operation. When the circular mounting shaft B stops rotating, the circular movable rod A and the circular movable rod B automatically reset under the action of the two helical springs B. When the circular mounting shaft B stops rotating, it is convenient for the staff to separate the circular mounting shaft A from the circular mounting shaft B, and it is also convenient for the staff to separate the circular mounting shaft B from the radiator fan, which is beneficial to subsequent maintenance and classified recycling.
[0021] 3. When the circular mounting shaft B rotates in the present invention, the synchronous pulley drives the external load to rotate, and the initial starting speed of the synchronous pulley can be lower than the speed of the circular mounting shaft B, avoiding damage to the present invention by the external load and playing an automatic protection effect. After using for a certain period of time, the staff can adjust the installation direction of the movable connecting seat to make the other half of the helical springs C bear force, improving the automatic protection effect.
[0022] 4. When the circular mounting shaft A rotates in the present invention, the auxiliary heat dissipation blades rotate, playing an auxiliary heat dissipation effect, and the auxiliary heat dissipation blades can move slightly to the left under the action of inertia. When the auxiliary heat dissipation blades can move slightly to the left under the action of inertia, the arc-shaped rubber block can automatically press the synchronous pulley tightly, so that the synchronous pulley can basically rotate simultaneously with the circular mounting shaft A during operation, and can appropriately reduce the compression times of the corresponding half of the helical springs C, which is beneficial to improving the service life of the helical springs C.
