Propeller for propelling ship

Abstract

The invention discloses a propeller for propelling a ship. The propeller comprises a propelling rod, the propelling rod is arranged on the outer side of a ship body, a propelling groove in sliding connection with the propelling rod is formed in the outer side of the ship body, a propelling propeller is arranged at the far end of the propelling rod, a lifting assembly and an auxiliary mechanism are arranged at the upper end of the propelling rod, the auxiliary mechanism is arranged on the bottom side of the ship body, a triggering mechanism is arranged in the ship body, when a driver drives a small speed boat to collide with reefs below the water surface, collision is detected through the triggering mechanism, the lifting assembly and the auxiliary mechanism are automatically controlled to lift the propelling propeller, and avoided is the situation that the propeller collides with an obstacle to cause damage and lose power, when the ship body climbs over the obstacle, therefore, a driver cannot drive the speed boat back to the shore, and potential safety hazards are caused.

Description

technical field [0001] The present invention relates to the technical field of ships, in particular to a propeller for propelling ships. Background technique [0002] Ships (boats and ships), a general term for all kinds of ships, ships are means of transportation that can sail or berth in waters for transportation or operations, and have different technical performance, equipment and structural types according to different use requirements. Man-made means of transportation mainly operating in geographical water. In addition, civilian ships are generally called ships, military ships are called ships, and small ships are called boats or boats. They are collectively called ships or boats. and drainage structures, with propulsion systems utilizing external or own energy. [0003] During the use of small speedboats, due to the low altitude and high speed, the operator cannot give a good warning to the reefs below the water surface during driving, and often cannot avoid it when ...

AI Technical Summary

Problems solved by technology

[0003] During the use of small speedboats, because of their low height and high speed, the operator cannot give early warning of the reefs below the water surface during driving, and often cannot avoid them when they are found. Because of the small weight of small speedboats, the speedboat It will directly climb over the reef, but the propeller propeller at the rear end of the hull is lower than the bottom of the ship, and it will directly hit and cause damage. As a result, although the hull is not seriously damaged, it loses power and cannot drive back to the shore again. For this reason, we propose to use Propellers for propulsion of ships
