[0030] In the application, the signal wire assembly 4 can transmit signals and electricity, and is not limited to signal transmission only, so that the underwater engine can be controlled to be turned on or off.

[0031] The power slip ring can be used in any electromechanical system requiring continuous rotation and transmitting power and signals from a fixed position to a rotating position, so as to avoid wire injury during rotation, and the existing gear transmission structure does not have space for arranging the power slip ring.

Since the use scene of the propeller is water, the control assembly 2 is located above the water surface, and the underwater engine 3 is below the water surface. During the operation of the underwater engine 3, the water near the underwater engine 3 will continuously surge and splash, resulting in long-term wetness of the housing 1. Since the lower housing 12 is closer to the water surface, the wetness and damage of the lower housing 12 will be much higher than that of the upper housing 11 in the same period of time, resulting in that the lower housing 12 is more likely to be scrapped than the upper housing 11. The detachably connected lower housing 12 can be regularly replaced without the need to disassemble and replace the entire housing 1, thereby reducing maintenance cost, improving maintenance efficiency and safety, and improving sealing and waterproof performance to avoid damage of important parts such as the bridge gear 53 and the signal line assembly 4 due to wet water.
