A tilting structure of a marine propeller

Abstract

The invention relates to a warped swing type structure of a propeller for a ship. The structure comprises a base connected to a ship rail and a movable base used for being connected with a hanging rod. The movable base can rotate relative to the base. The structure is characterized in that a spring bolt is also fixed to a bottom plate of the base, the movable base is rotationally provided with a locking block, the locking block is provided with a toothed groove matched with the spring bolt, and when the toothed groove of the locking block meshes with the spring bolt and is in a locked state, the movable base is kept at the position where the hanging rod is in a vertical state; when the toothed groove of the locking block is separated from the spring bolt and in an unlocked state, the movable base can warp, swing and rotate relative to be base. It is clear that the movable base can rotate relative to the base only in the unlocked state, and the propeller is driven to turn over and leave the water surface; the locking block and the spring bolt are located on the ship rail, so the locking block is very convenient to drive. The whole structure is simple, the cost is low, and accordingly the structure is very worthy of application and popularization on existing ships, especially on small ships like kayaks.

Description

technical field [0001] The invention relates to a fixing structure of a marine propeller, in particular to a tilting structure of a marine propeller. Background technique [0002] The marine propeller extends to the water surface through the hanging rod to drive the ship. When the ship sails in the reef area, the intricate reefs pose a great threat to the propeller. At this time, the usual practice is to lift the propeller out of the water and manually Manual rowing forward. Furthermore, the propeller is a relatively expensive marine component. It is easy to be corroded or adsorbed by shellfish in seawater for a long time, which will seriously affect the propulsion performance or even be damaged. Therefore, it is best to lift the marine propeller out of the water after berthing. [0003] The existing marine propellers have complex fixing structures, and most of the marine propellers need to disassemble the entire propeller from the side of the ship and then bring it out of ...

AI Technical Summary

Problems solved by technology

The structure is relatively simple, but when lifting the propeller, an upward pulling force is required to lift the propeller first, and the operation is laborious

[0005] Another example is a Chinese utility model patent "lifting and tilting full-rotation paddle" with the patent number ZL201120536497.0 (the announcement number is CN202389585U), which discloses a hydraulic cylinder drive to achieve the purpose of tilting the marine propeller, although the efficiency is high and labor-saving , but the cost of the structure is high, the assembly is complicated, and the thrust clip for unlocking is located under the side of the ship, so the unlocking operation is very inconvenient
