Description

Technical Field

[0001] This utility model relates to the field of ship design technology, and in particular to a steel ship structure with a modular counterweight system. Background Technology

[0002] Ship draft generally refers to the depth of a ship submerged in water, specifically the straight distance from the bottom of the ship to the point where the hull meets the waterline. It indirectly reflects the buoyancy experienced by the ship during navigation. A greater draft indicates a greater cargo-carrying capacity, and varies depending on the ship's design. Draft depends not only on the weight of the ship and all its cargo, such as cargo, ballast, fuel, and spare parts, but also on factors such as water density, ship speed, and wind direction and speed. The ballast system plays a crucial role in ship design. By adjusting the weight distribution on board, it influences the ship's buoyancy and stability. The ballast system can increase or decrease the ship's weight, thereby regulating the draft.

[0003] Traditional steel ship ballast systems use fixed ballast tanks or simple counterweight blocks, resulting in a fixed distribution of counterweights that cannot be dynamically adjusted to adapt to cargo loads or complex sea conditions, leading to increased sailing resistance and energy consumption.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] One embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, the main hull 1 is a composite frame structure of carbon fiber and high-strength steel. The key positions of the hull bottom use EH47 crack-arresting steel with a yield strength ≥460MOPa to reduce the overall weight. Hollow skeletons 12 are interlaced on the bulkheads inside the main hull 1. The internal ballast material is filled in and they also serve as hull reinforcement, improving space utilization. A fixed plate 11 is horizontally installed on the bottom of the hull. A modular counterweight system 2 is set above the fixed plate 11. The modular counterweight system 2 includes multiple independent counterweight compartments 21 and a sliding rail assembly 22 set on the top of the counterweight compartments 21. The counterweight compartments 21 are equipped with U-shaped counterweight units 211. The sliding rail assembly 22 is fastened to the fixed plate 11 and spans across at least two sets of counterweight compartments 21. The high-strength steel and carbon fiber composite frame achieves a balance between lightweight and high strength. The modular counterweight compartments integrate load-bearing functions and improve space utilization. The position of the counterweight blocks is dynamically adjusted through a threaded screw mechanism to adapt to the center of gravity balance requirements under different cargo load conditions.

[0021] The slide rail assembly 22 includes a mounting bracket 23 connected to the fixed plate 11. The mounting bracket and the fixed plate at the bottom of the ship are connected by high-strength bolts and epoxy resin. A horizontally arranged first slide rail 221 is installed on the surface of the crossbar of the mounting bracket 23. A first lead screw 222 located inside the mounting bracket 23 is arranged between the two sets of first slide rails 221. A first servo motor 223 is connected to the end of the first lead screw 222. A first connecting plate 24 is connected to the surface of the first slide rail 221 through a slider. The back of the first connecting plate 24 is fixedly connected to the lead screw nut on the first lead screw 222. A vertically arranged second slide rail 224 is installed on the side of the first connecting plate 24 away from the first slide rail 221. In this embodiment, the slide rail assembly is arranged along the length of the main hull. The first servo motor drives the first lead screw to drive the gripper cylinder to clamp the counterweight unit and move it back and forth in the horizontal direction to achieve the balance of the ship's center of gravity.

[0022] The second slide rail 224 is connected to the second connecting plate 25 via a slider. The first connecting plate 24 at the top of the second connecting plate 25 is equipped with a second servo motor 225. The output end of the second servo motor 225 is connected to a second lead screw 226. The lead screw nut on the second lead screw 226 is fixedly connected to the second connecting plate 25. The second servo motor drives the second lead screw to move the gripper cylinder vertically up and down while holding the counterweight unit. The slide rail assembly realizes the horizontal and vertical position adjustment of the counterweight unit, dynamically adjusts the position of the counterweight block, and adapts to the center of gravity balance requirements under different load conditions.

[0023] A vertically arranged gripper cylinder 26 is installed on the side of the second connecting plate 25 away from the second slide rail 224. A displacement sensor is installed at the end of the second connecting plate 25 on the side of the gripper cylinder 26. A detection plate matching the displacement sensor is provided on the upper surface of the U-shaped counterweight unit 211. The real-time position of the gripper cylinder is monitored by the displacement sensor, which makes it easy to clamp the counterweight unit and place it in the empty counterweight compartment or to vertically stack it with existing counterweight units.

[0024] The upper surface of the U-shaped counterweight unit 211 has a groove, and a handle 2111 is installed in the groove. The upper surface has raised positioning posts 2112 on both sides of the groove, and the lower surface has stepped positioning holes 2113 corresponding to the positioning posts 2112. The U-shaped counterweight unit 211 is composed of a steel outer shell 2114 on the surface and a high-density environmentally friendly material 2115 filled inside. The steel outer shell can be made of zinc-plated nickel alloy for rust prevention, and the high-density environmentally friendly material can be made of high-density tungsten iron alloy. The weight of a single counterweight unit is 50kg to 200kg. Vertical stacking and combination are achieved through the structure of positioning blocks 2112 and positioning holes 2113.
