Specifically, firstly, the impeller 2 is protected by the bottom plate 1 and the upper plate 5 to prevent the impeller 2 from friction during the installation process in the later stage, which affects the rotation speed of the impeller 2, and also prevents the impeller 2 from getting entangled during operation. The bottom end of the bottom plate 1 is provided with a protective component 3, which can extend the installation height of the impeller 2 to prevent the impeller 2 from being assembled on the water pump shaft and being damaged by friction. The threaded tube 302 of the protective tube 301 can be arranged between the connecting tube 303 to increase the spacing between the bottom plate 1 of the impeller 2 and the water pump. The anti-friction component 4 is arranged on the outer wall of the protective component 3 to protect and warn the bottom end of the impeller 2. When the distance between the bottom plate 1 and the rear end of the water pump is close, it will cause The reinforcement frame 402 in the middle of the fixing ring 401 and the water pump produce a friction sound, thereby reminding people that the impeller 2 is subjected to friction, and asking people to adjust the impeller 2 in time to effectively prevent the impeller 2 from being damaged by friction. The positioning plate 403 of the fixing ring 401 is locked at the bottom end of the base plate 1 by bolts 404 for positioning and locking. Finally, an upper plate 5 is provided at the top of the impeller 2, which is convenient for passing the shaft of the water pump through the upper plate 5 of the impeller 2 and the middle part of the shaft sleeve 6 for installation. Through this technical solution, the problem of friction damage to the impeller 2 during installation is solved, and a protective component 3 is provided at the bottom end of the base plate 1 to extend the installation height of the impeller 2 to prevent the impeller 2 from being assembled on the water pump shaft and being damaged by friction. The threaded tube 302 of the protective tube 301 can be arranged between the connecting tube 303 to increase the spacing between the base plate 1 of the impeller 2 and the water pump for regulation.

[0033] Further, such as Figure 1 and Figure 2 As shown: the inner wall of the bottom end of the base plate 1 is also provided with an anti-friction component 4. The advantage of this technical solution is that the positioning plate 403 of the fixing ring 401 is locked to the bottom end of the base plate 1 by bolts 404 for positioning and locking.

[0034] The above solution still has the problem that it is not convenient to protect the bottom of the impeller 2.

A protective component 3 is provided at the bottom end of the bottom plate 1 to extend the installation height of the impeller 2 and prevent the impeller 2 from being damaged by friction when assembled on the water pump shaft. The threaded tube 302 of the protective tube 301 can be arranged between the connecting tube 303 to increase the spacing between the bottom plate 1 of the impeller 2 and the water pump. The ring is provided with an anti-friction component 4, which can protect and warn the bottom end of the impeller 2. When the distance between the bottom plate 1 and the rear end of the water pump is close, the reinforcement frame 402 in the middle of the fixed ring 401 and the water pump will produce a friction sound, thereby reminding people that the impeller 2 is subjected to friction. People are requested to adjust the impeller 2 in time to effectively prevent the impeller 2 from being damaged by friction. The positioning plate 403 of the fixed ring 401 is locked to the bottom end of the bottom plate 1 by bolts 404 for positioning and locking.
