Description

Technical Field

[0001] This utility model belongs to the field of marine power equipment technology, specifically a hydrodynamic layout azimuth propeller. Background Technology

[0002] With the development of the shipping industry, the requirements for ship maneuverability and propulsion efficiency are getting higher and higher. The traditional ship propulsion method is mainly direct propulsion by propeller. Early ship propellers had relatively simple layouts and fixed power transmission directions. Ship steering mainly relied on rudder blades. When the ship is sailing at low speed or needs precise maneuvering, the rudder efficiency will decrease, and the ship's maneuverability will be affected.

[0003] Existing traditional rudder systems have certain limitations in steering. The rudder is typically mounted in a fixed position at the stern, limiting its steering angle and response speed. For vessels requiring rapid maneuvers in narrow waters or complex channels, such as tugboats and ferries, traditional rudders may not meet the requirements. Furthermore, long-term seawater immersion causes corrosion and oxidation, making disassembly difficult; if one blade fails, the entire rudder needs replacement, resulting in wasted resources. This new system improves the time and labor efficiency of blade replacement and installation.

[0004] Therefore, this utility model provides a hydrodynamic layout azimuth propeller. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The inner part of the cover body 2 is movably connected to the connecting cylinder 1. The connecting cylinder 2 is movably installed at one end of the connecting cylinder 1. The protective cover is fixedly connected to one end of the connecting cylinder 2. The inner part of the protective cover is movably connected to the rotating shaft. The outer side of the rotating shaft is fixedly connected to bevel gear 2 and bevel gear 3 respectively. The bevel gear 3 and bevel gear 2 are respectively meshed with bevel gear 1 on one side. The rotating shaft is equipped with an installation assembly. The blade is movably installed inside the installation assembly.

[0008] Preferably, the mounting assembly includes a sleeve, an internally threaded rod connected to the sleeve, an externally threaded blade connected to the threaded rod, a reinforcing plate on one side of the blade, and a threaded sleeve at one end of the threaded rod, the threaded sleeve being located on one side of the reinforcing plate.

[0009] Preferably, the turntable is located inside the second cover, and a first column is sleeved inside the turntable. An oil tank is provided on one side of the first and second oilers, and the oil tank is connected to the first and second oilers respectively through oil pipes.

[0010] Preferably, one end of the column is fixedly connected to a bevel tooth, and the outer side of the bevel tooth is respectively engaged with a bevel tooth and a bevel tooth.

[0011] Preferably, a second nut is provided inside one end of each of the first connecting cylinder and the second connecting cylinder, and the first connecting cylinder is movably connected to one end of the second connecting cylinder through the second nut.

[0012] Preferably, a nut is provided inside one end of each of the first and second covers, and one end of the second cover is movably connected to the first cover via the nut.

[0013] Preferably, a mounting bracket is fitted onto the outer side of the second shroud, and the mounting bracket is located on one side of the shroud.

[0014] Preferably, one end of the protective cover is fixedly connected to a flow guide, and two sets of flow guide plates are provided on the outer side of the flow guide, the flow guide plates being streamlined.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The hydrodynamic layout of the azimuth propeller described in this utility model drives the second column to rotate via the output shaft of the second engine. The second column drives the second gear to rotate, the second gear meshes with the first gear to rotate, the first gear drives the turntable to rotate, the turntable drives the first column to rotate horizontally, and the first column drives the protective cover to rotate inside the second cover, thereby enabling rapid adjustment of course, flexible docking at the pier, and meeting the navigation needs of ships under various conditions.

[0017] 2. The hydrodynamic layout of the azimuth propeller described in this utility model addresses the issue that prolonged immersion in water can lead to corrosion and oxidation of the propeller blades. Furthermore, the blades are easily damaged by impacts with debris in the water. The propeller blades are connected to one end of a sleeve via a threaded rod. A threaded sleeve is installed at one end of the threaded rod, and a reinforcing plate is threaded onto one end of the threaded sleeve. The reinforcing plate is located on one side of the propeller blade, effectively improving the stability of the propeller blade during operation.
