[0027] Working principle: when it is necessary to maintain and overhaul the motor 2, it is only necessary to rotate the insert 8.

The heat conducting plate 15, the heat sink 16, the heat sink 17 and the heat dissipation holes 18 play the role of introducing the heat generated when the motor 2 is working into the heat sink 16 and the heat sink 17 through the heat conducting plate 15, and then the heat sink 16 and the heat sink 17 introduce the heat into the water, thereby ensuring the sealing and waterproof effect while also improving the heat dissipation efficiency of the motor 2.
