Abstract

The invention discloses a marine propeller protection net, which comprises a net cover arranged on the periphery of the propeller and connected with the bottom of the hull; The protective net at the bottom of the propeller, the protective net at the bottom of the propeller and the rear protective net of the propeller are connected to each other and are respectively connected to the bottom of the hull; the present invention arranges a net cover around the propeller of the ship, which does not affect the effect of the water flow and the propeller, and can block the impact of foreign objects The propeller, and debris such as weeds or fishing nets are not easy to touch the propeller, and it is not easy to wrap around the propeller, which ensures the life of the propeller and the safety of the ship.

Description

technical field [0001] The invention relates to a protective net, in particular to a ship propeller protective net. Background technique [0002] Usually, the engine of the ship is arranged at the rear of the hull, and the engine is connected to the propeller through the transmission shaft. The propeller of some small ships is usually exposed at the rear bottom of the hull. This kind of ship has the following safety hazards during driving: [0003] 1. When in the shallows, the propeller is easy to collide with the stones at the bottom of the water, and the propeller is easy to be damaged; [0004] 2. When there are weeds or fishing nets and other sundries in the river, it is easy to wrap around the propeller, increasing the load on the engine, and even making the propeller unable to rotate. [0005] Therefore, the propellers of existing small ships need to be equipped with protective devices, so that the propellers are not easily damaged by foreign objects, and debris such...
