Description

Technical Field

[0001] The utility model relates to the technical field of boat propellers, in particular to an anti-winding propeller for boat propellers. Background Art

[0002] my country is a major shipping nation, and the shipping industry plays a vital and irreplaceable role in my country's economic development. This has been particularly true since the reform and opening-up policy. my country's shipping industry has experienced rapid growth, with over 80% of my country's import and export cargo now transported via shipping. The shipping industry has made significant contributions to promoting national economic growth and foreign trade, and holds a dominant position in my country's foreign trade. The health of a ship's propulsion system directly determines its overall safety. A ship's propeller is a crucial component of the propulsion system, acting as an energy converter within the propulsion system. It converts the engine's power into thrust, overcoming resistance in the water. The most important element is the propeller.

[0003] During navigation, the area between the propeller hub and the ship's stern shaft frame is often entangled by ropes, fishing nets, seaweed, algae, etc. in the water, causing the propeller to get stuck. This not only affects the normal operation of the ship, but may even cause major safety accidents with the destruction of the aircraft and the loss of life. The current treatment method is generally to stop the engine and sail, send divers to the sea to cut the entanglement with a knife, or use other ships to tow the ship to the shore or port, run aground and tow it to remove the entanglement.
