Technology realization elements

Technical realization elements:

3. This technology provides a marine propeller to solve the problem that the circuit parts on the existing marine propellers are directly exposed, and the user directly grabs the circuit parts and moves, so that the circuit parts are stressed, thereby reducing the service life of the marine propeller The problem.

4. In order to solve the above technical problems, this technology proposes a marine propulsion, including a power device, which is detachably connected to the hull through a fixed seat; a controller, which is connected to the power device through a wiring component, and is used to control the operation of the power device ; Circuit parts and protective parts, the circuit parts extend outward from the inside of the power unit; the protective parts are sheathed with the circuit parts, and the circuit parts or protective parts are sealed and fixed to the power unit in at least one place; the protective parts include a sealing fixture, and the protective parts are sealed through The holder is sealed and fixed to the circuit piece.

5. Among them, the protective part is a bellows, and the bellows is sleeved on the circuit part.

6. The seal holder includes: a connecting portion, one end of the connecting portion is connected to the end of the corrugated tube; a wire holding base, one end of the wire holding base is connected to the other end of the connecting portion, and is sleeved on the circuit component; a first wire holding sealing body , The first wire-holding sealing body is sleeved on the circuit component, and is filled between the wire-holding base body and the circuit component.

7. Among them, the marine propeller includes a support rod, the line component is penetrated through the support rod and is connected to the power device, the support rod is sealed and connected with the power device, and the line component is sealed and fixedly connected with the support rod.

8. Wherein, the end of the support rod far away from the power device is hermetically connected with the end of the guard, or the end of the support rod far away from the power device is hermetically connected with the circuit member.

9. One end of the fixed seat is connected with the power unit, and the other end is connected with the hull; the end face of the fixed seat connected with the hull is arranged in the same shape as the hull.

10. Among them, the controller includes a controller box body and a flip cover, and the flip cover is provided with a connection point between the circuit component and the controller box body.

11. Wherein, the controller includes a line card and a fixing part, the circuit part is penetrated through the fixing part and is sealed to the fixing part, and the fixing part is connected to the surface of the controller box body and clamped in the line card.

12. Among them, the power plant includes a motor, and the circuit components include a three-phase line of the motor.

13. Among them, the hull is equipped with equipment to be stored; the motor forms a back electromotive force, and the controller recovers the back electromotive force formed by the motor through the circuit parts, and charges the back electromotive force to the equipment to be stored.

14. The beneficial effect of this technology is: different from the existing technology, this technology provides a marine propulsion device, including a power unit, a circuit component, a controller, and a protective component. The circuit component or the protective component is sealed and fixed to at least one place. Power plant to improve the sealing of marine propellers. At the same time, the protective parts are sheathed with circuit parts, and the protective parts include a sealed retainer and a sealed retainer

The protective parts are sealed and fixedly connected to the circuit parts. Therefore, the mutual cooperation of the protective member and the sealing fixture can not only protect the outer surface of the circuit member, but also prevent the protective member from moving relative to the circuit member; at the same time, the direct force on the circuit member can be reduced, thereby further protecting the circuit member.
