Description

Technical Field

[0001] This utility model belongs to the field of ship design technology, specifically relating to a roll chamber structure and a fully automatic anti-roll system for ships. Background Technology

[0002] When a ship is loading or unloading cargo (such as containers) at a port, the ship will experience lateral tilting and rolling due to changes in cargo load; or when the ship's beam is narrow, the ship will experience lateral rolling due to the action of waves or wind, which greatly affects the ship's operational safety and comfort; the current common practice is to install anti-roll fins to reduce the impact of ship tilting on the ship.

[0003] Using anti-roll fins to reduce the effects of heeling on a ship presents the following problems:

[0004] 1. The cost of purchasing and installing anti-roll fins is high.

[0005] 2. Anti-roll fins are only effective in reducing heel when the ship is sailing at high speed.

[0006] 3. Anti-roll fins are located on the outside of the ship and are affected by marine crustaceans, resulting in high maintenance and repair costs, often requiring regular dry-dock overhauls. Utility Model Content

[0007] To address the technical problems existing in the prior art, this utility model provides a tilting compartment structure that can also serve as a ballast tank for the ship's hull, comprising:

[0008] The anti-heeling compartment has a U-shaped structure and is installed in the midship section according to the hull shape. The vertical parts on the left and right sides of the anti-heeling compartment correspond to the two sides of the hull, and the connecting part at the bottom of the anti-heeling compartment corresponds to the bottom of the hull. By ballasting seawater at the position of the anti-heeling compartment, the center of gravity of the anti-heeling compartment is adjusted, thereby adjusting the attitude of the ship.

[0009] Furthermore, it also includes:

[0010] There are two gas pipelines in total, and the inlets of the two gas pipelines are located at the top of the vertical parts on the left and right sides of the anti-rollover compartment, respectively.

[0011] There are two exhaust pipes in total, and the outlets of the two exhaust pipes are located at the top of the vertical parts on the left and right sides of the anti-rollover compartment, respectively.

[0012] Furthermore, the gas pipeline is equipped with a gas delivery valve, and an air compressor is installed at the end of the gas pipeline.

[0013] Furthermore, the exhaust pipe is equipped with an exhaust valve, and the end of the exhaust pipe is located outside the ship.

[0014] Furthermore, the end of the exhaust pipe is located at the connection portion at the bottom of the anti-rollover compartment;

[0015] The ends of the two exhaust pipes are arranged in a cross manner, that is, the end of the exhaust pipe at the top of the left vertical part of the anti-roll cabin is located below the right vertical part of the anti-roll cabin, and the end of the exhaust pipe at the top of the right vertical part of the anti-roll cabin is located below the left vertical part of the anti-roll cabin.

[0016] Furthermore, the diameter of the exhaust pipe is 1.5 times that of the gas transmission pipe.

[0017] A fully automatic anti-roll system for ships, including the aforementioned roll chamber structure, further includes:

[0018] Inclinometers are used to monitor the tilt angle of a ship and transmit the monitoring results to the main controller in real time.

[0019] The main controller is used to adjust the center of gravity of the tilting cabin structure in the other direction according to the left and right tilting direction when the ship's tilt angle is greater than a preset value.

[0020] Furthermore, controlling the relevant equipment to adjust the center of gravity of the tilting cabin structure in the other direction according to the left and right tilting direction includes:

[0021] When the ship tilts to the left by more than a preset value, air is pumped into the vertical part of the anti-roll tank corresponding to the left side, while air is released from the top of the other vertical part of the anti-roll tank, causing the seawater in the anti-roll tank to gather to the right and adjusting the ship's center of gravity to the right.

[0022] When the ship lists to starboard beyond a preset value, air is pumped into the anti-roll tank and the vertical section corresponding to the starboard side, while air is released from the top of the other vertical section of the anti-roll tank, causing the seawater in the anti-roll tank to gather to the left and adjusting the ship's center of gravity to the left.

[0023] Furthermore, the air discharged from the top of the vertical section of the anti-roll chamber is guided and delivered to the bottom of the side of the ship in the direction of tilt, providing an upward force to the hull on that side and assisting in the adjustment of the ship's center of gravity.

[0024] Furthermore, it also includes:

[0025] The inspection circuit, which is connected to each device in the system, is used to check the working status of each device in the system and transmit the data to the main controller.

[0026] Pressure sensors installed on the inner wall of the anti-roll tank are used to monitor the position of ballast water inside the anti-roll tank and transmit the data to the main controller.

[0027] When any equipment in the system malfunctions and fails to start normally, the faulty equipment will send a resistance signal to the main controller via the PLC and issue an alarm. Alarms can be triggered at multiple critical locations. Furthermore, the operational status and the liquid level position information of the anti-tilt tank can be visually monitored at the alarm location.

[0035] Figure 1 This is a schematic diagram of the principle of this utility model. Detailed Implementation

[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] Reference Figure 1 This utility model consists of a U-shaped anti-tilt chamber, a high-power high-pressure air compressor, a main gas supply pipe, an exhaust pipe, an electric remote control butterfly valve, a sea-through check valve, an inclinometer, a pressure sensor, a liquid level and pressure sensor, cables, a junction box, a start-up control board (PLC), and other control panels.

[0038] The specific steps are as follows:

[0039] 1. First, according to the U-shaped anti-rolling compartment and ballast compartment of this utility model (hereinafter referred to as anti-rolling compartment), a U-shaped through compartment with left and right communication is set in the midship section of the ship according to the outer plating of the ship.

[0040] 2. Install the high-power high-pressure air compressor, main air supply pipe, exhaust pipe, electric remote control butterfly valve, and sea check valve according to the requirements of this utility model, and install the pipeline support and air compressor base. The inlet of the air supply pipe and the outlet of the exhaust pipe are both located at the top of the U-shaped anti-roll cabin; the outlet of the exhaust pipe extends to the outer side plate of the bottom of the specially made U-shaped anti-roll cabin, and after opening the hole, the exhaust pipe is welded to discharge the compressed air in the cabin to the outside; the diameter of the exhaust pipe is 1.5 times that of the air supply pipe.

[0041] 3. Install pressure sensors 1 and 2 at the highest positions on the upper part of the left and right anti-tilt chambers respectively; install liquid level pressure sensors 1 and 2 at the bottom left and right sides of the U-shaped anti-tilt chamber respectively. The main control panel program calculates the liquid level height based on the pressure values ​​of the liquid level pressure sensors.

[0042] 4. Connect the cables to the junction box of the high-power high-pressure air compressor and the electric remote control butterfly valve to the start control board; connect the start control board to the main / auxiliary control board, and connect the main control panel to the detection and alarm system;

[0043] 5. Install the inclinometer in the cab and connect it to the main control panel with a signal cable; connect pressure sensors 1 and 2, and liquid level pressure sensors 1 and 2 to the main control panel with signal cables respectively.

[0044] 6. When the ship is berthed, the anti-heeling compartment is unloaded and the entire system is in a stopped state;

[0045] 7. Before loading or unloading cargo or before sailing, fill the anti-roll tanks with seawater to 60% to 70% of their capacity using the ship's ballast system (monitored by liquid level and pressure sensors); at the same time, activate the anti-roll system button, and the system will start operating automatically and monitoring.

[0046] 8. The working principle of the anti-roll system is as follows:

[0047] a. When a ship encounters waves and rolls during loading / unloading or navigation, the inclinometer monitors the ship's tilt angle. When the tilt angle exceeds 2 degrees, the main controller detects the change in the port and starboard tilt angles and transmits the anti-roll system activation signal to the activation control board based on the port and starboard tilt direction. If the port tilt exceeds 2 degrees, the high-pressure air compressor starts, and simultaneously, the electrically controlled remote butterfly valve 1 opens. The air compressor delivers high-pressure compressed air to the port inlet of the U-shaped anti-roll compartment, increasing the internal air pressure at the upper port side of the U-shaped anti-roll compartment. At the same time, the electrically controlled remote butterfly valve 3 opens, releasing the U-shaped anti-roll... Compressed air in the upper starboard side of the heeling tank releases pressure at the upper starboard end, causing seawater in the U-shaped anti-heeling tank to gather on the starboard side, shifting the ship's center of gravity to the right, thus providing a reaction force 1 to the ship's heel. Simultaneously, high-pressure compressed air discharged through the electrically controlled butterfly valve 3 is delivered to the bottom of the port side tank and sprayed towards the seabed, providing an upward force 2 on the port side to counteract the ship's heeling force. Forces 1 and 2 work together to adjust the ship's heel, maximizing the use of spare capacity and reducing energy consumption, thus correcting the ship's heel angle to below 0.5 degrees. The reverse is also true.

[0048] b. When the pressure from pressure sensor 1 or 2 exceeds the set pressure, the main control panel sends a signal to the start control panel (PLC), causing the air compressor to stop operating. Simultaneously, the electric remote-controlled butterfly valve closes to prevent further pressure increase in the anti-listening compartment and potential damage to the compartment structure. At this point, it is necessary to increase the ballast water level of the entire ship to lower the center of gravity and prevent further ship listing.

[0049] 9. The anti-roll system can be remotely started and stopped via the main / auxiliary control panel. It can also be started and stopped via the local control panel and the start control panel.

[0050] 10. When the above equipment fails to start normally, the faulty equipment will feed back the resistance signal to the main control panel through the PLC and issue an alarm. The alarm can be triggered in multiple key locations (such as the bridge, ship's office, etc.). The operating status, liquid level of the port and starboard anti-roll tanks, etc. can be visually monitored in the above locations.

[0051] In summary, this is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification are within the scope of the present utility model patent.
