This process not only improves the heat dissipation efficiency, but also effectively reduces the working temperature of the driving device, ensuring its stable operation in underwater high-temperature environments. In addition, the layout of the stator assembly in the front cavity allows it to fully utilize the space provided by the front cavity for heat dissipation, further improving the heat dissipation effect.

The integrated design of the main cabin body 1 effectively integrates the control module 5 and the power module 6, not only ensures the stability of power supply and the accurate transmission of control instructions, but also greatly simplifies the system structure and improves the overall reliability and maintenance convenience. The electrical connection of the control module 5 and the power module 6, and the electrical connection of the control module 5 and the driver 4, realize efficient information transmission and energy conversion, and provide a solid foundation for the stable operation of the propeller. Secondly, the ingenious arrangement of the shell support 2 and the fixed support 3 further enhances the structural strength and stability of the propeller. As the supporting structure of the main cabin body 1, the shell support 2 can effectively resist the complex pressure and impact of the underwater environment, while the fixed support 3 ensures the firmness of the entire device during installation and use, reduces vibration and displacement caused by factors such as water flow fluctuation, thereby prolonging the service life of the equipment. Furthermore, as the core component of the propeller, the design of the driver 4 also embodies high professionalism and practicality. The optimized design of the driving fairing 7 effectively reduces water resistance and improves propelling efficiency; the driving device 8 is built into the fairing, which not only protects the internal mechanical structure from corrosion and damage, but also ensures the continuous and stable output of driving force; and the driving fan blade 9 maximizes the use of water flow power through precise angle and shape design, realizing efficient propulsion. The efficient, stable and reliable characteristics of the present application provide an ideal propelling solution for underwater vehicles, underwater robots and other fields.

[0043] Referring to Figures 5-11As shown, the driving device 8 includes a stator outer support 81, a stator inner support 82, and a stator assembly 83. The stator outer support 81 is provided with an outer connecting platform 811, a support shell 812, and a stator connecting end 813. The stator inner support 82 is provided with a driving shaft 821 and an inner connecting platform 822 arranged at one end of the driving shaft 821.

The stator assembly 83 is arranged on the driving shaft 821 and located in the front cavity 814. One end of the driving shaft 821 is sealingly connected to the stator connecting end 813. During heat dissipation, gas-liquid enters the rear cavity 823 from the gas-liquid inlet 8222, enters the front cavity 814 after passing through the rear cavity 823, and is then discharged from the gas-liquid outlet 8221. The ingenious design of the stator outer support 81 and the stator inner support 82, especially the close connection of the outer connecting platform 811 and the inner connecting platform 822, ensures the stability of the structure of the driving device 8. This design not only enhances the overall strength of the driving device 8, but also provides reliable support for its long-term operation in complex underwater environments. At the same time, the reasonable layout of the support shell 812, the front cavity 814, and the rear cavity 823 effectively optimizes the gas-liquid circulation path, reduces fluid resistance, and improves heat dissipation efficiency. Secondly, the sealing connection technology of the driving shaft 821 and the stator connecting end 813 ensures the closedness of the gas-liquid circulation system, effectively preventing water and other impurities in the underwater environment from entering the interior of the driving device 8, thereby ensuring the cleanliness and reliability of the system. This design is of great significance for prolonging the service life of the driving device 8 and reducing maintenance costs. Furthermore, the arrangement of the gas-liquid inlet 8222 and the gas-liquid outlet 8221, as well as their communication mode with the rear cavity 823, provides an efficient heat dissipation channel for the driving device 8. During heat dissipation, gas-liquid enters the rear cavity 823 from the gas-liquid inlet 8222, carries heat after sufficient heat exchange, enters the front cavity 814, and is finally discharged from the gas-liquid outlet 8221. This process not only improves the heat dissipation efficiency, but also effectively reduces the working temperature of the driving device 8, ensuring its stable operation in high-temperature underwater environments. In addition, the layout of the stator assembly 83 in the front cavity 814 enables it to fully utilize the space provided by the front cavity 814 for heat dissipation, further improving the heat dissipation effect. At the same time, this layout helps to reduce the vibration and noise of the stator assembly 83 during operation, improving the overall performance of the underwater propeller.

Secondly, the arrangement of the sealed connecting column 14 not only strengthens the connection strength of the sealed front cover 12 and the sealed rear cover 13, but also further improves the sealing performance of the whole main cabin body 1, so that the thruster can work stably for a long time in deeper water. Thirdly, the power switch 121 and the charging interface 122 arranged on the sealed front cover 12 not only facilitate operation and control, but also avoid the direct influence of the underwater environment on the interface through reasonable layout design, ensuring the normal switching of the power supply and the stable realization of the charging function. Finally, the sealed connecting seat on the sealed rear cover 13 provides a reliable connection point for the driving device 8, ensuring the stability and efficiency of the power output of the thruster. At the same time, this design also facilitates the maintenance and replacement of the driving device 8, reducing the maintenance cost of the thruster.

The close combination of the fixed side cover 21 and the main cabin body 1 provides a solid protective barrier for the propeller. Secondly, the connecting frame 31, as an important part of the fixed support 3, is ingeniously arranged on the fixed side cover 21, realizing the stable connection of the support and the propeller body.
