Description

Technical Field

[0001] The utility model relates to the technical field of propeller protection, in particular to a propeller comprehensive protection structure. Background Art

[0002] For ships that use propellers as propulsion, the power source converts power into propeller thrust on the ship through efficient and high-speed power output via the drive shaft and gears, which makes the propeller have a very high rotation speed and forms a huge and high-speed water flow around the propeller. When encountering water bodies containing large floating or suspended objects, aquatic plants such as water plants, fishing net ropes and other debris, the propeller directly exposed in the water body is easily entangled with the above-mentioned debris under the action of high-speed water flow.

[0003] When a ship is sailing, since the propeller is directly exposed in the water, it is easy for debris in the water to entangle the propeller, which will increase the engine load and even make the propeller unable to rotate. Therefore, there is a problem of debris in the water entangled in the propeller. In addition, when people on the ship fall into the water due to an accident or there are swimmers or divers in the navigation waters, the huge water flow formed by the high-speed rotation of the propeller that is not stopped in time can easily draw the people who fall into the water in time, and they cannot be protected in time. They are easily injured or even killed by the high-speed propeller, and other serious safety accidents. Therefore, there is a problem that people on the ship cannot be protected when they fall into the water or there are swimmers or divers. In summary, this utility model has the problem that debris in the water entangles the propeller and people on the ship cannot be protected when they fall into the water or there are swimmers or divers.
