Description

Simple streamline solid wood structure for ship

Technical Field

The utility model relates to a technical field of boats and ships, in particular to marine simple and easy streamlined dull wood structure.

Background

As is well known, the dead wood structure for the ship can protect the propeller and improve the course stability of the ship. When the ship is designed, the speed of each ship is strictly required, and under specific conditions, the conventional dead wood can be streamlined to properly reduce resistance, so that the rapidity and the economy of the ship are improved. At present, a piece of symmetrical stiff wood is arranged at the stern of some ships and at the center of a ship body below a propeller, the side projection area of the ships is increased through the stiff wood, the center of the side projection area of the ships deviates to the stern, and therefore the navigation stability of the ships can be improved. However, the added dead wood increases the wet surface area of the ship body, thereby increasing the resistance of the ship in sailing and improving the energy consumption of the ship in sailing.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide one kind can be when improving the stability of boats and ships navigation, reduce the energy consumption of boats and ships navigation and can effectively protect the marine simple and easy streamlined dull wood structure of screw.

The utility model adopts the technical proposal that: the utility model provides a marine simple and easy streamlined dull wood structure sets up on the hull of boats and ships afterbody, screw incoming flow one side, a marine simple and easy streamlined dull wood structure includes the dull wood subassembly, the overlook projection of dull wood subassembly is olive shape structure, the central line of this olive shape structure with the central line of screw is in on same vertical plane, the dull wood subassembly includes two edges the screw incoming flow direction is the dull wood planking of bilateral symmetry structure, the dull wood planking is close to the one end of screw is equipped with the inclined plane, the lower extreme on inclined plane is compared the lower extreme of screw is low.

As can be seen from the above solution, by providing the solid wood component with an olive-shaped structure, and the lower end of the inclined plane is lower than the lower end of the propeller, the propeller can be hidden behind the solid wood component during the driving of the ship body, i.e. the propeller can be effectively protected; in addition, the central line of the olive-shaped structure and the central line of the propeller are positioned on the same vertical plane, so that the incoming flow can flow into the propeller along the olive-shaped structure, the propelling efficiency of the propeller is improved, and the energy consumption is reduced.

Preferably, the outer wall surface of the solid wood outer plate is in an arc structure.

According to the scheme, the solid wood outer plate of the arc structure is arranged, so that incoming flow can enter the propeller along the arc structure.

Preferably, the inclined surface is inclined in a direction toward the propeller from a bottom end to an upper end thereof.

According to the scheme, after the incoming flow is guided by the stay wood outer plate with the arc-shaped structure, the incoming flow is guided by the inclined surface, so that the incoming flow can accurately flow into the propeller, and the propelling efficiency of the propeller is further ensured.

The hollow structure is provided with a plurality of transverse partition plates, and the end surfaces on the two sides of each transverse partition plate are respectively connected with the inner walls of the two solid wood outer plates.

According to the scheme, the transverse partition plate is arranged, so that the connecting strength of the solid wood outer plate is increased.

Preferably, the diaphragm plate is connected with the solid wood outer plate in a welding mode.

Preferably, the distance between any two adjacent diaphragm plates is consistent.

Preferably, the lower ends of the two solid wood outer plates are connected by welding.

The upper end face of the solid wood outer plate is attached to the lower end face of the tail of the ship body and is connected with the lower end face of the tail of the ship body in a welding mode, and the upper end face of the solid wood outer plate is of a streamline structure.

According to the scheme, the transverse partition plate and the solid wood outer plate, the lower ends of the solid wood outer plates and the upper end surface of the solid wood outer plate and the lower end surface of the tail of the ship body are connected in a welding mode, so that the connecting strength is high, and the solid wood outer plate is easy to disassemble and assemble.
