[0060] The implementation principle of the sewage pump in the embodiment of the application is as follows:

[0061] When the sewage pump needs to be moved, the connecting ring 91 is moved upward, the plurality of flaps 6 are slightly turned over under the gravity of the flaps 6 and the universal wheels 8 thereon, so that the plurality of flaps 6 are all separated from the corresponding limiting holes 12, then the connecting ring 91 is moved downward, the flaps 6 are driven to turn over in the direction of approaching the slot of the accommodating groove 3111 by the abutment of the stop blocks 10 against the end portions of the flaps 6 away from the hinge shafts, until the abutting blocks 92 abut against the end surfaces of the corresponding flaps 6 close to the pump body 1, at this time, the flaps 6 are flush with the abutting part 312, the rollers extend out of the abutting part 312, the plurality of flaps 6 are spliced to form the baffle 17, and the plurality of clamping blocks 931 are clamped into the corresponding positioning grooves 321 under the action of the elastic members two 932, thereby achieving the positioning of the connecting ring 91.

[0062] Then the universal wheels 8 abut against the ground, and the staff only needs to push the sewage pump, which can be moved by the rolling of the universal wheels 8 on the ground, without manual carrying or the aid of other tools, so that the sewage pump is more convenient to move.

[0063] When the sewage pump needs to be used, the mounting portion 142 is pressed in the direction close to the connecting ring 91, the mounting portion 142 drives the plurality of protrusions 15 to abut against the inclined surface 131 in the corresponding groove 13, thereby pushing the plurality of clamping blocks 931 to move away from the corresponding positioning groove 321, until the plurality of clamping blocks 931 are all separated from the corresponding positioning groove 321. At this time, the mounting portion 142 and the connecting ring 91 are connected through the adhesion of the magic male sticker 161 and the magic female sticker 16, so that the clamping block 931 remains in the state of being separated from the positioning groove 321. Then, the connecting ring 91 is moved close to the pump body 1 together with the adjusting ring 14, so that the clamping block 931 and the positioning groove 321 are misaligned, that is, the positioning state of the connecting ring 91 is released.

[0064] Then the flap 6 is flipped under the action of the elastic member one 7 to drive the universal wheel 8 to enter the containing groove 3111. At this time, each flap 6 is pressed to abut against the stop block 10 to push the connecting ring 91 to continue to move close to the pump body 1, until each flap 6 and the corresponding limiting hole 12 are aligned. The connecting ring 91 is lowered under the action of gravity, so that each flap 6 is clamped into the corresponding limiting hole 12. The limiting of the connecting ring 91 is realized by the abutment of the flap 6 against the inner wall of the limiting hole 12, and the limiting of the flap 6 is realized by the abutment of the inner wall of the limiting hole 12 against the flap 6, so that the flap 6 always abuts against the inner wall of the containing cavity 11.

[0065] Further force is applied to separate the mounting portion 142 and the connecting ring 91, that is, the magic male sticker 161 and the magic female sticker 16 are separated. The clamping block 931 moves close to the corresponding protruding column 32 under the action of the elastic member two 932, and the protrusion 15 is pushed to move upward through the inclined surface 131, so that the mounting portion 142 and the connecting ring 91 are separated, until the clamping block 931 abuts against the corresponding protruding column 32, for subsequent operation to position the connecting ring 91.

[0066] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
