This forms a three-layer sealing structure, providing a sealing protection for the permanent magnet, thereby ensuring excellent sealing performance.

[0060] The sealing process for the first sealing structure 523 and the second sealing structure 533 is as follows: firstly, silicone sealing treatment is performed with a silicone potting compound; secondly, encapsulating treatment is performed by the titanium alloy sheet to realize arrangement, fixation and connection of the coil or permanent magnet and other components in the first annular groove or the second annular groove, and a space is sealed with a plastic insulating medium while reserving the space for wiring terminals and thirdly, a polypropylene material is applied to the surface of titanium alloy and is neutralized with the sealing layer to form a three-layer sealing structure. By adopting this sealing structure, the motor operating noise may be effectively reduced, and the oil-electricity isolation safety during medium transportation is improved.

The electrical plug-in terminal 321 corresponds to the electrical connecting terminal 331. When the male connector 32 and the female connector 33 are mated, the electrical plug-in terminal 321 and the electrical connecting terminal 331 can be engaged with each other, thereby forming an electrical connection.

[0080] In the male connector 32 and the female connector 33 at the two ends of the hose 3, two ends of the signal line 31 are electrically connected to the electrical plug-in terminal 321 and the electrical connecting terminal 331 respectively. In the male connector 32 located on the reel 2, the electrical plug-in terminal 321 is electrically connected to the control device via a wire harness. In the female connector 33 located on the oil gun 9, the electrical connecting terminal 331 is electrically connected to the detection component in the oil gun 9. In the female connector 33 located at the oil supply end, the electrical connecting terminal 331 is electrically connected to the detection component in the oil supply end.

[0081] In the male connector 32 located on the reel 2, the electrical plug-in terminal 321 is connected via wiring. Further, referring to FIGS. 11 to 14, to prevent misalignment between the electrical plug-in terminal 321 and the electrical connecting terminal 331 during mating, a limit portion 322 is arranged at an end of the male connector 32, and a limit matching portion 332 is arranged in the female connector 33. The limit portion 322 and the limit matching portion 332 are engaged with each other, ensuring that the electrical plug-in terminal 321 the electrical connecting terminal 331 are correctly mated.

[0082] One of the limit portion 322 and the limit matching portion 332 is a limit protrusion, and the other one is a limit groove.

[0083] In one embodiment, referring to FIG. 11, the signal line 31 is spirally wound around the periphery of the hose 3, and the pitch at the two ends of the signal line 31 is smaller than the pitch at the middle of the signal line 31.

[0084] In this embodiment, the signal line 31 is spirally wound around the periphery of the hose 3. The signal line 31 is sparsely wound around the middle of the hose 3 and densely wound around the two ends of the hose 3. This non-uniform winding configuration of the signal line 31 effectively reduces the signal interference and enhances the structural strength of the signal line 31 during the winding process.

[0085] Further, to protect the signal line 31 and the hose 4, the periphery of the hose 3 is sequentially wrapped with an inner protective layer, a framework layer and an outer protective layer from inside to outside. The signal line 31 is spirally wound around the periphery of the framework layer.

[0086] In one embodiment, referring to FIG. 4, the driving assembly 5 further includes a magnetic isolation member 55, and the magnetic isolation member 55 is arranged on the stator assembly 52 and located between the two coil windings 522.

[0087] In this embodiment, since the first rotor assembly 53 and the second rotor assembly 54 rotate independently, a slot is formed in the middle of the stator core 521 to prevent the magnetic field interference between the first rotor assembly 53 and the second rotor assembly 54. The slot is arranged circumferentially around the stator core 521. The magnetic isolation member 55 is arranged in the slot. The radial cross-sectional area of the magnetic isolation member 55 is greater than that of the coil windings 522. This arrangement allows the magnetic isolation member 55 to shield against the interference between power magnetic fields.

[0088] In one embodiment, referring to FIGS. 8 to 10, the marine oil hose reel further includes a hose arrangement device 7. The hose arrangement device 7 is arranged on the mounting frame 1 and provided with a mounting member 74 reciprocating in the first direction. The hose 3 extends through the mounting member 74.

[0089] In this embodiment, the hose arrangement device 7 is mounted on front sides of the two side frames and located in front of the reel 2. By the hose arrangement device 7, the hose 3 is driven to reciprocate in the first direction during winding and unwinding, ensuring the orderly arrangement of the hose 3.

[0090] In this embodiment, referring to FIGS. 8 to 10, the hose arrangement device 7 includes a mounting base 71, eight synchronous pulleys 72 and a synchronous belt 73. The mounting base 71 is mounted on the mounting frame 1. The eight synchronous pulleys 72 are arranged on the mounting base 71 in an array, and each synchronous pulley 72 is rotatably arranged along an axis in a second direction. The synchronous belt 73 is sleeved onto the eight synchronous pulleys 72. The mounting member 74 is located in the synchronous pulleys 72 and connected to the synchronous pulleys 72. One of the synchronous pulleys 72 is connected to the connecting piece 8 via a transmission assembly 75, so that the rotation of the connecting pieces 8 drives the synchronous pulley 72 to rotate. The first direction is perpendicular to the second direction. In actual use, when the reel 2 rotates, the connecting piece 8 drives the synchronous pulleys 72 to rotate through the transmission assembly 75, and then the synchronous pulleys 72 drive the synchronous belt 73 to move, which drives the mounting member 74 to reciprocate in the first direction, thereby achieving hose arrangement.

[0091] Specifically, the transmission assembly 75 includes two belt pulleys 751, a belt 752, a rotating shaft 753, a driving bevel gear 754 and a driven bevel gear 755. The rotating shaft 753 is rotatably mounted on a front side of the mounting frame 1 along the axis in the second direction. One of the belt pulleys 751 is fixedly connected to the connecting piece 8, and the other belt pulley 751 is mounted on the rotating shaft 753. The belt 752 connects the two belt pulleys 751. The driving bevel gear 754 is mounted on the rotating shaft 753. The driven bevel gear 755 is fixedly connected to the one of the synchronous pulleys 72. The driving bevel gear 754 is meshed with the driven bevel gear 755. In this way, the rotation of the connecting piece 8 can be transmitted to the synchronous pulleys 72, enabling the hose arrangement device 7 to operate without the need for additional power devices, thereby reducing the cost.

[0092] Further, when the mounting member 74 moves by the driving of the synchronous belt 73, the mounting member 74 itself also rotates around the axis in the second direction. To prevent the hose 3 from being twisted, the mounting member 74 includes a mounting plate 741 and a mounting disc 742. The mounting plate 741 is movably mounted on the mounting base 71 in the first direction and located in the synchronous belt 73. The mounting plate 741 is connected to the synchronous belt 73. A through-hole is formed in the middle of the mounting plate 741. The mounting disc 742 is mounted in the through-hole via a bearing. A via hole is formed in the middle of the mounting disc 742 and configured to allow the hose 3 to pass through. In this way, the mounting disc 742 can rotate relative to the mounting plate 741, thereby preventing the hose 3 from being twisted.

[0093] Further, to reduce the friction between the via hole and the hose 3, the mounting member 74 further includes four horn-shaped rollers 743. The four horn-shaped rollers 743 are respectively arranged on upper, lower, left and right sides of the via hole, each horn-shaped roller 743 is rotatably arranged along its own axis, and the hose 3 abuts against the horn-shaped rollers 743, converting sliding friction into rolling friction, thereby reducing the frictional force, and prolonging the service life of the hose 3.

[0094] Further, the two horn-shaped rollers 743 on the upper and lower sides are elastically stretchable in a vertical direction. This arrangement enables the two horn-shaped rollers 743 to tightly clamp the hose 3.
