Problems solved by technology
[0005] In order to solve the above-mentioned technical problems, the present invention provides an energy-saving attachment structure in front of the propeller of a ship to solve the problem that when the existing attachment structure in front of the propeller is in use, the position of the propeller is usually in contact with objects in the water, and it is easy to Cause damage, make the propeller unusable, cannot remove the objects in contact with the propeller in the water in advance, and the existing structure of the front attachment of the propeller cannot divert the water flow according to the demand, so that the propeller cannot be better When the propeller is in contact with the water flow, it is easier to push the boat under force when the propeller is rotating, making the boat faster

The invention provides an energy-saving appendage structure in front of a ship propeller. The energy-saving appendage structure comprises a main body, a connecting rod, a guide piece, a flow guide piece and a bottom plate; the front end of the main body is of a conical structure, and a paddle body is mounted at the front end of the main body; the main body comprises a paddle body and a connectingpiece; threaded holes are formed in the upper and lower ends of the main body; a connecting piece is arranged at the front end of the paddle body; the connecting piece is of a T-shaped circular structure; and the flow guide piece is used for being installed at the foremost end of the device. When the device is used, the device can be located at the foremost end through the flow guide part to guidewater flow, therefore, the pressure on the paddle body is reduced; and if an object is about to impact the propeller body, the object can be in contact with the propeller body through the flow guidepiece, the front end of the flow guide piece is of a wedge-shaped structure, and in the moving process of the ship, the flow guide piece can divide the object needing to impact the propeller body, sothat the object can be broken and flow towards the two sides, and the object is prevented from directly impacting the propeller body.
Description
technical field [0001] The invention belongs to the technical field of supporting mechanisms for ships, and more specifically relates to an energy-saving attachment structure in front of a ship's propeller. Background technique [0002] The appendages below the design waterline of the ship, such as the bilge keel, rudder, shaft frame, shaft and sleeve frame, etc., are collectively referred to as the appendages of the ship, and the resistance due to the existence of the appendages is called the appendage resistance. [0003] For example, the application number: CN201920126475.3 relates to an energy-saving attachment structure in front of the ship oars, including guide fins, and the guide fins include a first sheet body arranged horizontally and a second sheet body arranged vertically. The front side is fixed to the stern of the ship, the first sheet is vertically connected to the second sheet in a cross shape, the first sheet is inclined upward from front to back, and its tri...
