The implementation principle of the embodiment 3 is as follows: when the barring works, the pushing piece 4 pushes the ejector head 3 to move towards the driving motor shaft 10 until the insertion end abuts against the rear end face of the driving motor shaft 10, when the fixture block 31 just corresponds to the clamping groove 100, the fixture block 31 is clamped in the clamping groove 100, and the barring motor 2 drives the driving motor 1 to operate to carry out barring work; when the fixture block 31 does not completely correspond to the clamping groove 100, the fixture block 31 elastically abuts against the rear end face of the driving motor shaft 10, the barring motor shaft 20 is slowly rotated, when the fixture block 31 corresponds to the clamping groove 100, the fixture block 31 is pushed into the clamping groove 100 under the pushing of the elastic piece 32, the fixture block 31 is tightly clamped with the clamping groove 100, and the barring motor 2 is started to drive the driving motor 1 to operate so as to perform barring. By arranging the shell 30, the clamping blocks 31 and the elastic pieces 32, the convenience of butting the insertion end of the ejector head 3 with the driving motor shaft 10 is improved.
The embodiment of the application also discloses a water pump with barring gear. Referring to fig. 2, the water pump with the barring gear comprises a pump body 8 and a driving motor 1 for driving the pump body 8 to operate, and the barring gear is fixedly connected to a rear end cover 11 of the driving motor 1.
The implementation principle of the water pump with barring gear of the embodiment of this application is: driving motor 1 can provide power for the operation of the pump body 8, when the adhesion takes place for the water pump and the incrustation scale results in that driving motor 1 start load can the grow even be difficult to the operation, the barring device can drive driving motor shaft 10 forced operation, until driving motor 1 can normal boot, at barring during operation, need not carry out the dismouting to water pump external component, accomplish automatic barring through the cooperation of barring motor 2, impeller 4 and ejector head 3, improve the convenience of water pump barring work.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
