Specifically, the third-stage planet carrier 2321 and the flange end cover 233 are rotatably fitted through the seventh bearing 2327, and the third-stage input shaft 2324 and the flange end cover 233 are rotatably fitted through the sixth bearing 2326. The third-stage input shaft 2324 is coaxially and fixedly connected to the second-stage planet carrier 2221, and the second-stage planet carrier 2221 and the third positioning frame 223 are rotatably fitted through the fifth bearing 2227. Thus, the third positioning frame 223 indirectly rotatably supports the third-stage input shaft 2324, that is, the overall forms a support for the third-stage reduction component 232, which can share the radial load of the third-stage reduction component 232, reduce the tooth-to-tooth impact, reduce noise, and improve the service life. Similarly, the inner wall of the third-stage annular shell 231 is formed with a third-stage annular gear 2325. By adopting an integrally formed structure, the number of parts can be simplified, the integration degree is high, and the assembly process is simplified.

[0077] Further, referring to Figures 1-4 , in some embodiments, the third-stage reduction component 232 further includes a plurality of support guide wheels 2329. Each support guide wheel 2329 is rotatably mounted on the third-stage planet carrier 2321 and is arranged at intervals in a circular array around the third-stage input shaft 2324. Among them, the inner wall of the third-stage annular shell 231 is further formed with an annular slideway 2311 surrounding the plurality of support guide wheels 2329. Each support guide wheel 2329 is respectively in rolling fit with the annular slideway 2311. Thus, the third-stage annular shell 231 can further rotatably support the third-stage planet carrier 2321, making it have higher stability and reliability.

[0078] Referring to Figures 1-4 , in some embodiments, the second positioning frame 214 is provided with a plurality of first guide through holes 2141. The first guide through holes 2141 communicate the internal space of the first-stage annular shell 211 with the internal space of the second-stage annular shell 221. Such a design allows the lubricant to freely flow and lubricate between the internal space of the first-stage annular shell 211 and the internal space of the second-stage annular shell 221 when filling with lubricant for lubrication.

[0079] Similarly, in some embodiments, the third positioning frame 223 is provided with a plurality of second guide through holes 2231. The second guide through holes 2231 communicate the internal space of the second-stage annular shell 221 with the internal space of the third-stage annular shell 231. Such a design allows the lubricant to freely flow and lubricate between the internal space of the second-stage annular shell 221 and the internal space of the third-stage annular shell 231 when filling with lubricant for lubrication.

[0080] In some embodiments, with reference to Figures 2-7 , the marine electric direct-drive hatch opening module further includes a magnetic shield 300 and a centrifugal fan 400. The magnetic shield 300 is disposed on the speed reduction mechanism 200 and covers the permanent magnet motor 100. One end of the rotor 130 facing away from its output end extends out of the housing 110 and is provided with a centrifugal fan 400. The magnetic shield 300 is provided with an air inlet 310 and an air outlet 320. The air inlet 310 is axially opposite to the centrifugal fan 400 along the axis of the centrifugal fan 400, and the air outlet 320 is located in the radial direction of the centrifugal fan 400. The magnetic shield 300 plays a role in magnetic isolation, suppressing the magnetization effect of the permanent magnet of the rotor 130 on other components. The centrifugal fan 400 can be of an existing structure, capable of sucking external air into the magnetic shield 300 through the air inlet 310 to blow air on the housing 110 for heat dissipation, and discharging the hot air through the air outlet 320.

[0081] In addition, with reference to Figure 3 and Figure 5 , in some embodiments, a manual drive jack 131 is provided at one end of the rotor 130 of the marine electric direct-drive hatch opening module where the centrifugal fan 400 is installed. Thus, when the marine electric drive module fails to be electrically driven, the magnetic shield 300 can be removed, and then an existing rotating swing rod can be inserted into the manual drive jack 131 for emergency manual rotation. The rotating swing rod is an existing auxiliary tool and will not be elaborated herein. The manual drive jack 131 can be a hexagonal prism hole or a prism hole of other shapes.

[0082] In some embodiments, with reference to Figures 2-7 , a plurality of heat dissipation plates 111 are formed by protruding from the outer peripheral wall of the housing 110. The heat dissipation plates 111 are beneficial to increasing the heat dissipation area and improving the heat dissipation speed.

[0083] In some embodiments, with reference to Figures 2-7 , the housing 110 further has a first cavity 112 and a second cavity 113. The first cavity 112 is provided with a power processing module, and the second cavity 113 is provided with a servo control module. An integrated one-piece structure design is adopted, with a compact structure and high integration.

[0084] Furthermore, the power processing module and the servo control module can refer to the electric vehicle drive module, with good speed regulation linearity and stable low-speed large-torque load; in some embodiments, the permanent magnet motor 100 can integrate an AC variable frequency and a rectified DC speed regulation dual mode for selection.

[0085] The marine electric drive module provided by the embodiments of the present application can adjust the reduction ratio and the power size design of the permanent magnet motor 100, achieving a maximum output torque of 17,000 N·m, and can meet the needs of the general opening and closing driving force. In addition, it can be designed for expansion in the form of this structure when multi-purpose requirements are needed, such as further changing the reduction ratio and further changing the input motor power.

[0086] In some embodiments, the material of the first positioning bracket 213 is a magnetic isolation material, which can suppress the magnetization influence of the permanent magnet motor 100 on the components of the reduction mechanism 200.

[0087] In addition, some embodiments of the present application further provide a ship opening and closing control system. The ship opening and closing control system includes a console and a plurality of marine electric drive modules provided by any of the above embodiments. The console is electrically connected to each marine electric drive module through a signal line and a power cable respectively, and each marine electric drive module is used to control the opening and closing of at least one cabin of the ship.

[0088] The ship opening and closing control system provided by some embodiments of the present application can perfectly replace the hydraulic motor drive device of the general old design. A sprocket is installed on the output taper shaft 2328 of the marine electric drive module, and other installation modes are the same as the general mode. The hydraulic power station, hydraulic control station, hydraulic oil pipe and valve parts are cancelled, and only the power cable and communication line need to be laid.

[0089] Furthermore, some embodiments of the present application further provide a marine electric direct drive module to implement similar drive control.

[0090] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0091] The above embodiments only represent one implementation mode of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
