[0030] As shown in Figure 1 and Figure 2 The detachable fluid paddle of the present application comprises a paddle body 100 and three paddles 200 distributed on the outer circumference of the paddle body 100. The end of the paddle body 100 towards the power device is provided with two elastic buckles 102 corresponding to the power device in the axial direction. Through the above structural design, when installing, the transmission gear on the output shaft of the power device is clamped by the elastic buckle, so that the present application is installed on the output shaft of the power device. When disassembling, external force is applied to overcome the friction between the elastic buckle and the teeth of the transmission gear, so that the present application is separated from the transmission gear on the output shaft of the power device, thereby realizing the quick disassembly of the present application and the power device, reducing the maintenance time and cost.

[0031] Specifically, the paddle body 100 has a receiving cavity 101 with an opening towards the power device. Six teeth 103 are arranged on the circumferential inner wall of the receiving cavity 101. A tooth groove 104 is formed between two adjacent teeth 103. Two elastic buckles 102 correspond to two tooth grooves 104. Through the above structural design, the teeth of the transmission gear of the power device are engaged with the tooth grooves 104. At the same time, the elastic buckle 102 is clamped on the teeth due to the correspondence between the elastic buckle 102 and the teeth of the transmission gear of the power device, thereby ensuring the stable connection between the present application and the power device. That is, the teeth on the paddle body 100 and the tooth grooves on the output gear of the power device are in a tight fit relationship, without the need for screws or nuts for fixation. After installation, the paddle works stably and does not swing.

[0032] Specifically, the paddle body 100 is provided with a notch 105 corresponding to the tooth groove 104. The elastic buckle 102 is arranged on the bottom of the notch 105. The elastic buckle 102 comprises a buckle body 1021 and a reverse buckle protrusion 1022 arranged on the inner side of the free end of the buckle body 1021.

[0033] As a preferred mode of the embodiment, the free end of the buckle body 1021 is inclined inward, and when the transmission gear on the output shaft of the power device is inserted into the accommodating cavity 101, the inwardly inclined free end can be easily clamped on the teeth of the transmission gear.

[0034] As a preferred mode of the embodiment, the outward side of the undercut protrusion 1022 is an inclined surface, facilitating the insertion of the transmission gear on the output shaft of the power device into the accommodating cavity 101, and the inward side is a circular arc surface, facilitating the application of external force to make the transmission gear on the output shaft of the power device disengage from the application.

[0035] As shown in Figure 3 and Figure 4 The application is applied to an underwater sewage suction machine, which comprises a power device 300 and a sewage suction assembly 400 detachably connected with the power device 300, and a transmission gear is installed on the output shaft of the power device 300, i.e. the motor, and the transmission gear comprises a gear body and six teeth distributed on the outer circle of the gear body. When installing, the transmission gear is inserted into the accommodating cavity 101 of the application, and because the elastic buckle 102 corresponds to the teeth of the transmission gear, the elastic buckle 102 is clamped on the teeth of the transmission gear, thereby completing the stable connection between the application and the power device, and finally the sewage suction assembly 400 is installed.

[0036] In summary, the application has the characteristics of reasonable structure, easy disassembly and assembly, and low cost by the above structural design, which solves the deficiencies in the prior art.

[0037] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0038] The above-described embodiments only express several implementation manners of the application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the application, some modifications and improvements can be made, which are all within the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
