The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, a propeller 10 for use in water, comprising: a sealed housing 11, a controller 13, a motor 14, a battery 15 and a pump impeller 16. The controller 13 and the battery 15 are mounted in the sealed housing 11. The motor 14 is fixed to one end of the hermetic case 11. The pump impeller 16 is connected to the motor 14 and is driven to rotate by the motor 14. Both the motor 14 and the controller 13 are electrically connected to the battery 15. The battery 15 can power the controller 13 and the motor 14. The controller 13 controls the motor 14 to rotate, and the motor 14 rotates to drive the pump jet propeller 16 to realize the propelling operation.
As a further structure, the hermetic case 11 includes: a body 111 and an end cap 12. A motor housing 141 of the motor 14 is coupled to one end of the body 111 to seal one end of the body 111. The end cap 12 is connected to the other end of the body 111 to seal the other end of the body 111. End cap 12 includes an outer end cap 121 and an inner end cap 122. The inner end cap 122 is connected to the other end of the body 111 by screw threads. Inner end cap 122 is formed with a threaded bore 1221. The inner side of the outer end cap 121 is provided with a bolt 1211. Outer end cap 121 is secured to the outside of inner end cap 122 by bolts 1211 threaded into threaded bores 1221. The body 111 is formed with an internal thread at an inner side thereof and an external thread at an outer side of the inner end cap 122. When mounting, the inner end cap 122 is first connected to the other end of the body 111 by internal and external threads. Bolts 1211 on the inside of outer end cap 121 are then screwed into threaded holes 1221 to fix outer end cap 121 to the outer periphery of inner end cap 122. The manner of sealing the body 111 by the outer end cap 121 and the inner end cap 122 facilitates the removal of the end cap 12 while ensuring the sealing property. That is, the end cap 12 is separated into two parts, i.e., an inner end cap 122 and an outer end cap 121, which are screwed together by bolts 1211: when the sealing shell 11 needs to be opened, the outer end cover 121 is unscrewed, and then the inner end cover 122 is unscrewed; when the sealing shell 11 needs to be sealed, the inner end cap 122 is screwed, and then the outer end cap 121 is screwed. The end cover 12 with the structure has simple structure and convenient disassembly, and simultaneously does not increase the cost.
As a specific embodiment, a plurality of supporting portions 1222 are formed on a side of the inner end cap 122 away from the body 111. The support portion 1222 is used for supporting the outer end cap 121, thereby ensuring the stability of the mounting structure of the outer end cap 121 and avoiding the outer end cap 121 from being depressed and broken due to external pressure.
Specifically, the number of the supporting portions 1222 is 2. The center line of threaded hole 1221 coincides with the center line of inner end cap 122. The 2 support portions 1222 are oppositely disposed about the center line of the inner end cap 122, and the structure is more stable.
As a specific embodiment, the outer end cap 121 is a round end cap 12. The rounded end cap 12 reduces the resistance of the seal housing 11 in the water, thereby reducing the power consumption of the propeller.
Further, several recesses 1212 are distributed on the outer side of the outer end cap 121. The several recesses 1212 are evenly distributed in the circumferential direction of the outer end cap 121. These recesses 1212 are used to facilitate the user's rotation of the outer end cap 121.

In a specific embodiment, a wireless receiving module 19 is further disposed in the sealed housing 11. The wireless receiving module 19 is communicatively connected to the controller 13 and an external remote control unit. The wireless receiving module 19 receives a control signal transmitted from an external remote control unit and transmits the control signal to the controller 13. The controller 13 controls the pump jet 16 according to the control signal.
As a specific embodiment, the body 111 includes: an upper housing 1112 and a lower housing 1113. The upper shell 1112 and the lower shell 1113 are fixedly connected, and sealant is filled at the joint of the two to form a sealed cavity 1114.
As a specific embodiment, the pump jet 16 includes an aft nacelle 161 and blades 162. The rear cowling 161 is connected to the motor housing 141 of the motor 14. The paddle 162 is connected to the shaft of the motor 14. One end of the shaft of the motor 14 is rotatably connected to the rear pod 161. When the motor 14 rotates, the paddle 162 is driven to rotate, thereby generating the propelling force.
As a further alternative, a transfer member 20 is provided in the body 111. The middle rotating part 20 is used for connecting and fixing the cables inside the body 111, so as to ensure the tidiness of the cables inside the body 111 and the stability of the cable connection structure. The middle rotating part 20 is detachably connected to the inside of the body 111 and is located at the other end of the body 111 to facilitate the dismounting of the cable. The transit member 20 is formed with a plurality of connection holes 201. The cable is fixed in the connection hole 201, and then the transfer member 20 is installed in the body 111. The power switch 17 and the charging interface 18 are both mounted to the relay member 20 and are both electrically connected to the battery 15 through a cable fixed to the relay member 20. The wireless receiving module 19 is mounted on the relay unit 20 and is communicatively connected to the controller 13 and an external remote control unit
Further, a plurality of card slots 1111 are formed at the inner side of the body 111. The transit member 20 is formed with a plurality of projections 202. Protruding 202 and draw-in groove 1111 cooperation can demountable installation transfer part 20, can also prevent transfer part 20 to produce simultaneously and rotate to guarantee cable connection structure's stability, prevent that the cable from taking off the line. When the rotation member 20 is inserted into the body 111, the protrusion 202 is engaged with the engaging groove 1111.
