Embodiment Construction

[0059] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0060] Such as Figure 7 and Figure 8 Shown is a general layout diagram of the tail of a ship in the prior art. The present invention describes the process of improving and designing the tail structure in combination with the general layout of the tail of the ship in the prior art. Such as Figure 7 As shown, the tail structure includes a tail peak tank 21, a tail shaft cooling water tank 22, a propeller 23 and a rudder arm 14, the tail peak tank 21 is arranged on the upper end of the tail shaft cooling water tank 22, and the propeller 23 is connected to the tail shaft cooling water One side of the cabin 22 and one side of the aft peak tank 21 are provided with a rudder arm 14 connected with a rudder; Such as Figure 8 As shown, it is a schematic diagram of the mid-longitudinal section of the stern structure, including th...

Abstract

The invention discloses a ship stern post, which comprises an outer plate, a shaft hub and round steel, and one end of the shaft hub extends out of the outer plate and is used for being connected with a propeller of a ship; the round steel extends along the outer contour line of the outer plate; the outer plates comprise the first outer plate and the second outer plate, the end face of the first outer plate and the end face of the second outer plate are connected with the outer wall of the round steel, and the diameter of the round steel is larger than the wall thickness of the first outer plate or the second outer plate. By adopting the invention, the tail end connecting position of the outer plate is moved forwards, namely, the connecting position of the original middle longitudinal section is moved to the position tangent to the outer edge of the round steel. According to the structure, the internal operation space of the ship body is increased, and the construction manufacturability is effectively improved. In addition, the round steel replaces a part of the outer plate, correspondingly, the size of the outer plate is reduced, and therefore the machining difficulty of the outer plate is lowered, especially the outer plate with the tail portion provided with bidirectional curvature.

Description

technical field [0001] The invention relates to a ship stern post. Background technique [0002] The stern post is the member at the rear end of the hull used to connect the outer plates and keels on both sides, including propeller post 10, rudder post 11 and stern frame bottom bone 12, etc.; moment. The type of stern post is related to the type of rudder and the number of propellers. For conventional ships, such as oil tankers and bulk carriers, usually only one propeller is installed; for ships with special requirements for maneuverability, only two or more propellers are installed, such as engineering ships and military ships. Therefore, conventional The type of stern post on a ship is only related to the type of rudder. The rudders used in some of the existing ships are multi-supported rudders. The stern post structure on this ship not only has a propeller post, but also has a rudder post and a stern frame bottom bone. figure 1 shown. The rudders used on some ships ...
