Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0024] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. Example

[0025] like Figure 1-9As shown, the present application discloses a multifunctional underwater electric auxiliary equipment, including a power device 100 and any one of a first load device 200 and a second load device 300 detachably connected to the power device 100. In this embodiment, the power device 100 adopts a motor, the first load device 200 is a propeller blade assembly, and the second load device 300 is a sewage suction assembly. The power device 100 and the first load device 200 are assembled into an underwater propeller, and the power device 100 and the second load device 300 are assembled into an underwater sewage suction machine.

[0026] Specifically, when the power device 100 and the first load device 200 are assembled into an underwater propeller, when the power device 100 starts the motor, a power output gear 101 is installed on the output shaft of the motor, and the power output gear 101 includes a gear body 1011, and a mounting hole 1012 is provided at the middle position of the gear body 1011. The gear body 1011 is provided with teeth 1013 distributed on the circumferential outer circle. According to actual application requirements, the number of teeth 1013 can be set to 3-10 to meet different product requirements. In this embodiment, the number of teeth 1013 is six. The end of the teeth 1013 facing the first load device 200 is a curved surface guide meshing design, that is, the end of the teeth 1013 facing the first load device 200 is a curved surface 1015.

[0027] The first load device 200 is a propeller blade assembly, which includes a first load end 201, a housing, etc. The first load end 201 has a first accommodating cavity 2011 adapted to the power output gear 101. Through the above structural design, during installation, it is only necessary to make the power output gear 101 correspond to the first load end 201, and the power output gear 101 can be inserted into the first load end 201 at any angle. Because the power output gear 101 and the corresponding end of the first load end 201 are both designed with arc-guided meshing, the power output gear 101 has a large rotation resistance and is relatively fixed. The first load end 201 is connected to a blade that can rotate freely without rotational resistance. When the arc surface end of the power output gear 101 contacts the arc surface end of the first load end 201, the arc surfaces are tangent to each other, so that the first load end 201 is subjected to force and rotates an angle, so that the power output gear 101 can be smoothly inserted into the first accommodating cavity 2011 of the first load end 201, thereby enabling rapid disassembly and assembly of the power device and the first load end, reducing maintenance time and cost, and enabling the gear connection to be performed even in a blind spot, that is, under invisible conditions, which greatly improves installation speed and efficiency.

[0028] Typically, the blades in the blade assembly in this embodiment are installed in the shell of the blade assembly near the rear end of the shell, so that the first load end 201 is located near the rear end of the shell. At the same time, the output shaft length of the motor is fixed. If the traditional motor shaft and blade rigid connection technology is used, the disassembly and assembly will be quite troublesome and complicated. When installing using the present application, it is only necessary to insert the power output gear 101 into the shell of the blade assembly. The power output gear 101 can be easily inserted into the first load end 201 by blind insertion. Finally, the power device 100 and the first load device 200 are assembled by rotating the shell of the first load device 200 and the snap-in structure on the power device.

[0029] Specifically, when the power device 100 and the second load device 300 form an underwater sewage suction machine, the second load device 300 is a sewage suction assembly, which includes a second load end 301, and the second load end 301 has a second accommodating cavity 3011 adapted to the power output gear 101; the second load end 301 is axially arranged with an even number of elastic buckles 3012 that match the power output gear. In this embodiment, there are two elastic buckles 3012. The structural design is that when installing, it is only necessary to make the second load end 301 correspond to the power output gear 101, and the elastic buckle 3012 is locked on the teeth 1013 of the power output gear 101, so that the second load end 301 is installed on the power output gear 101; when disassembling, an external force is applied to overcome the friction between the elastic buckle and the teeth of the power output gear, so that the second load device 300 is separated from the power output gear 101 on the output shaft of the power device, so that the application and the power device can be quickly disassembled and assembled, reducing maintenance time and cost. In this embodiment, the second load end 301 includes a blade body and three blades distributed on the circumferential outer circle of the blade body, and the end of the blade body facing the transmission is axially oppositely provided with two elastic buckles 3012 that match the power output gear.

[0030] In this embodiment, the second load end 301 is independent of the second load device 300 and is first installed on the power device 100. During installation, the power output gear 101 is inserted into the second accommodating cavity 3011 of the second load end 301. Since the elastic buckle 3012 corresponds to the teeth 1013 of the power output gear 101, the elastic buckle 3012 is locked on the teeth of the power output gear. Finally, other components of the second load device 300 are installed to complete the final installation.

[0031] Specifically, a tooth groove 1014 matched with the first tooth 2012 is formed between two adjacent teeth 1013, the first teeth 2012 are distributed on the circumferential inner wall of the first accommodating cavity 2011, and a first tooth groove 2013 matched with the tooth 1013 is formed between two adjacent first teeth 2012. Through the cooperation between the teeth 1013 and the first tooth groove 2013 and the first teeth 2012 and the tooth groove 1014, the power output gear 101 and the first load end 201 can be well assembled together. Similarly, the second teeth 3013 are distributed on the circumferential inner wall of the second accommodating cavity 3011, and a second tooth groove 3014 matching the teeth 1013 is formed between two adjacent second teeth 3013. Through the cooperation between the teeth 1013 and the second tooth groove 3014 and the cooperation between the second teeth 3013 and the tooth groove 1014, the power output gear 101 and the second load end 301 can be well assembled together.

[0032] Specifically, the two elastic clips 3012 correspond to the two second tooth grooves 3014. Through the above-mentioned structural design, the teeth 1013 are meshed with the second tooth grooves 3014. At the same time, since the elastic clips 3012 correspond to the teeth 1013, the elastic clips 3012 are stopped on the teeth 1013, ensuring a stable connection between the second load end 301 and the power device 100.

[0033] Specifically, the blade body is provided with a notch corresponding to the second tooth groove 3014, and the elastic buckle 3012 is provided on the bottom of the notch. The elastic buckle 3012 includes a buckle body 3012a and an undercut protrusion 3012b provided on the inner side of the free end of the buckle body 3012a.

[0034] As a preferred mode of this embodiment, the free end of the buckle body 3012a is inclined inwardly, and when the power output gear 101 is inserted into the second accommodating cavity 3011, the free end inclined inwardly can be easily stopped on the teeth 1013 of the power output gear 101.

[0035] As a preferred embodiment of this embodiment, the side of the undercut protrusion 3012b facing the power output gear 101 is an inclined surface, which facilitates the insertion of the power output gear 101 into the second accommodating cavity 3011, and the side away from the power output gear 101 is an arc surface, which facilitates the application of external force to disengage the power output gear 101 from the second load end 301.

[0036] In summary, the end of the tooth 1013 facing the first load device 200 or the second load device 300 is designed as an arc-guided meshing design, and the end of the first tooth 2012 facing the power output gear 101 is designed as an arc-guided meshing design. Through the above-mentioned structural design, since the ends of the tooth 1013 and the first tooth 2012 are both designed as an arc-guided meshing design, the blind insertion operation of the power output gear and the first load end becomes easier to operate and simpler, and the assembly of the power output gear 101 and the second load end 301 only requires direct insertion, so that the power device can easily switch the load device, that is, it can be easily assembled with the first load device or the second load device. Since only one universal power device is needed to realize two different functions of the equipment, the purpose of rich functions and low cost is achieved. Of course, other underwater electric equipment can also be changed accordingly according to the structure of the present application, and the same power device can be shared to realize multiple functions.

[0037] The present invention solves the deficiencies in the prior art through the above-mentioned structural design, and has the characteristics of reasonable structure, low cost, strong practicality, etc.

[0038] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
