[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] As Figs. 1 to 3As shown, a detachable impeller assembly includes a ring-shaped base 1 and a plurality of clamping assemblies, the clamping assemblies are fixedly installed on the ring-shaped base 1 in a circumferential array, the clamping assemblies include an installation arm 2 and an installation clamping plate 3, the installation arm 2 and the installation clamping plate 3 have a gap 4 for installing blades therebetween, the installation arm 2 and the installation clamping plate 3 also have a locking piece for locking the blades therebetween, and a reinforcing assembly is fixedly arranged between adjacent clamping assemblies.

[0029] Specifically, when installing the blades, the installation arm 2 is fixedly connected with the ring-shaped base 1, and the installation clamping plate 3 is fixedly connected with the ring-shaped base 1, a gap 4 for inserting the blades is reserved between the installation arm 2 and the installation clamping plate 3, then the blades are inserted into the gap 4, and finally the blades are locked by the locking piece, so that both sides of the blades are clamped. The embodiment clamps the blades in the gap 4 between the installation arm 2 and the installation clamping plate 3, and locks the blades by the locking piece, which not only retains the high strength of the inserted impeller, but also retains the advantages of convenient external clamping installation and low cost. At the same time, each group of clamping assemblies is designed to be detachable, which is convenient for subsequent maintenance and maintenance.

[0030] A plurality of installation grooves 5 are fixedly arranged on the ring-shaped base 1, and one end of the installation arm 2 is fixedly arranged in the installation groove 5. Specifically, inserting the end of the installation arm 2 into the installation groove 5 can make the end of the installation arm 2 more stable.

[0031] One end of the installation clamping plate 3 is fixedly connected with the ring-shaped base 1 by a first bolt assembly 7. Specifically, after aligning the position of the installation clamping plate 3, the installation clamping plate 3 is fixed on the ring-shaped base 1 by the first bolt assembly 7.

[0032] An upper limiting plate 6 is also included, which is fixedly connected with the ring-shaped base 1 and is pressed against the top of all the installation arms 2. Specifically, the upper limiting plate 6 presses the installation arms 2 from the top down, avoiding the installation arms 2 from being tilted up due to the gravity of the blades, and maintaining the stability of the installation arms 2.

[0033] The installation arm 2 is fixedly connected with the ring-shaped base 1 by a second bolt assembly 9, the second bolt assembly 9 penetrates the installation arm 2, the ring-shaped base 1 and the upper limiting plate 6, and the first bolt assembly 7 penetrates the installation arm 2, the ring-shaped base 1, the upper limiting plate 6 and the installation clamping plate 3. Specifically, the first bolt assembly 7 and the second bolt assembly 9 are both installed in a penetrating manner, so that the connection between the ring-shaped base 1, the installation arm 2, the upper limiting plate 6 and the installation clamping plate 3 is more stable.

[0034] The locking member comprises a third bolt assembly 10 which penetrates the mounting arm 2, the blade and the mounting plate 3. Specifically, the blade is locked by the third bolt assembly 10, so that the blade has good ability to bear transverse shear force.

[0035] The reinforcing assembly comprises a plurality of reinforcing plates 11 which are arranged in a circumferential array, and the two ends of each reinforcing plate 11 are fixedly connected with two adjacent mounting arms 2. Specifically, the reinforcing plates 11 connect all the mounting arms 2 into a whole, so that the whole impeller assembly has high integrity and high strength.

[0036] The middle part of the annular base body 1 has a shaft sleeve hole 12, and a shaft sleeve 13 is fixedly arranged in the shaft sleeve hole 12, and the shaft sleeve hole 12 and the shaft sleeve 13 are both conical. Specifically, the fan often shakes left and right due to external environmental interference when running, which increases the eccentricity of the motor shaft, increases the loss and reduces the expected service life of the motor. Therefore, the conical shaft sleeve 13 and the shaft sleeve hole 12 are arranged, so that the annular base body 1 is self-locked under the action of gravity, and the falling of the annular base body 1 is effectively prevented.

[0037] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
