The invention discloses a combined four-blade propeller for a bulk carrier, which comprises a main body and a casing. Drainage grooves are arranged on the left and right sides of the main body, and the casing is located inside the main body. A guard plate is provided, and the guard plate and the main body are fixedly welded, and the guard plate and the casing are fitted together; a rotating shaft is installed inside the casing, and fan blades are connected to the surface of the rotating shaft. The leaf and the rotating shaft are in fitting connection; the twisting suction cylinder is arranged inside the rotating shaft, and the twisting suction cylinder and the rotating shaft are in fitting connection. The four-bladed propeller for bulk carriers is provided with a main body, which is mainly used as an installation base to facilitate the installation of the shell, and at the same time protect the shell and the parts inside the shell to prevent underwater impact and damage to the shell. A drainage groove is provided, and the setting of the drainage groove can mainly reduce the underwater resistance.
Description
technical field [0001] The invention relates to the technical field of propellers, in particular to a combined four-bladed propeller for bulk carriers. Background technique [0002] With the continuous increase of the freight market, air, land and water are the main transportation methods. Among them, the cost of air transportation is relatively high, while land transportation generally takes a long time and has certain limitations on the transportation of goods. Water transportation plays an important role in material transportation. Most of the world uses bulk carriers for transportation, and bulk carriers are mainly used to transport unpacked goods. [0003] When the bulk carrier is transported, it mainly relies on the rotation of the propeller to move. The propeller is also an essential part of the bulk carrier. Among them, the four-bladed propeller is the most used propeller. In order to ensure the safety of the bulk carrier in water transportation Advantages, improvem...
