Description

Technical Field

[0001] This utility model relates to the field of marine technology, specifically to an electric propulsion device for ships. Background Technology

[0002] Ships are a general term for all kinds of vessels. They are means of transportation that can navigate or anchor in waterways for transport or operations. Ships are usually equipped with propulsion equipment. The most common propulsion device used for small ships is the propeller. Propellers include electric and fuel-powered types. Electric propellers mainly include a brushless motor, propeller blades, control stick, control handle, and adjustment frame.

[0003] However, existing electric propellers suffer from the following problems during operation: During the propeller's rotation in water, it is sometimes affected by aquatic plants, which can become entangled on the blades, hindering their normal operation. A common method is to install a net around the outside of the propeller blades to prevent this. However, even with this method, aquatic plants can accumulate on the net surface over time. Failure to clean this net promptly will affect the propulsive performance and increase energy consumption. Therefore, a corresponding technical solution is needed to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide an electric propulsion device for ships, which solves the problem that during the rotation and propulsion of propeller blades in water, they are sometimes affected by aquatic plants. The aquatic plants can become entangled on the propeller blades, affecting their normal operation. Usually, a net cover is installed on the outside of the propeller blades to prevent the aquatic plants from getting entangled on the blades. However, with the net cover protection method, aquatic plants can remain on the surface of the net over time. If they are not cleaned in time, they will affect the propulsion effect of the propeller blades and increase energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric propulsion device for a ship, comprising a brushless motor, propeller blades, an operating lever, a control handle, and an adjustment frame. The power output end of the brushless motor is connected to the propeller blades. The lower end of the operating lever is connected to the brushless motor, and the upper end is connected to the control handle. The adjustment frame is installed in the middle of the operating lever. A protective shell is fitted onto the brushless motor. A protective mesh is installed at the front end of the protective shell. Several sets of reinforcing ribs are formed on the protective mesh, and a gap is formed between adjacent sets of reinforcing ribs. A movable peeling assembly is provided on one side of the protective mesh. The movable peeling assembly includes a movable ring and an inclined... The assembly includes a rod and a cutting blade. The moving ring is slidably mounted on the protective shell and has several sets of mounting holes evenly distributed on its surface. Several sets of inclined rods are evenly rotatably mounted within these mounting holes. The outer end of each inclined rod is slidably mounted on a reinforcing rib. The outer end of each inclined rod is connected to two symmetrically arranged sets of cutting blades, which are located within a spacer groove. An adjustment mechanism is provided on one side of the movable peeling assembly. The adjustment mechanism includes a connecting rod, a guide plate, and a return spring. Two sets of connecting rods are symmetrically mounted on both sides of the moving ring. The upper end of each connecting rod is slidably mounted on the guide plate. One end of the return spring is connected to the guide plate, and the other end is connected to the upper end of the connecting rod.

[0006] In a preferred embodiment of this utility model, the diameter of the mounting opening is larger than the diameter of the inclined rod, and one end of the inclined rod is rotatably mounted inside the mounting opening.

[0007] In a preferred embodiment of this utility model, the diagonal bar is inclined, and the surface of the diagonal bar is machined with a groove, the width of which is greater than the diameter of the reinforcing rib.

[0008] In a preferred embodiment of this utility model, the cutting blade is generally disc-shaped with blade-shaped edges, and the thickness of the middle part of the cutting blade is greater than the thickness of the edges.

The collar is fixed to the operating rod, and two sets of sliding grooves are symmetrically opened at the bottom of the horizontal plate. The upper end of the connecting rod is slidably disposed in the sliding groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model improves the structure of the existing electric propeller thruster by equipping the propeller blade net with a movable stripping component and an adjustment mechanism at the tail of the movable stripping component.

The ring 10 is slidably mounted on the protective shell 6 and has several sets of mounting holes 13 evenly opened on its surface. The diagonal rods 11 are divided into several sets and are evenly rotated and installed in the several sets of mounting holes 13.
