Description

Technical Field

[0001] The invention relates to the field of shipboard equipment, and in particular to a ship anti-sway device. Background Art

[0002] With the development of the global shipping industry, the problem of ship rolling is becoming increasingly serious, especially in severe sea conditions. Ship rolling not only affects the comfort of navigation, but also may endanger the safety of crew members and the stability of cargo. In order to solve this problem, ship roll reduction technology has been widely studied and applied in recent years. Among them, liquid roll reduction tanks, as an effective anti-roll device, have become an important part of modern ship design. Traditional liquid roll reduction tanks usually use seawater to enter or discharge the tanks through pipes to adjust the volume of liquid in the tanks, thereby using the inertia of the liquid to reduce the ship's rolling.

[0003] However, the existing liquid anti-rolling tank system has certain limitations, especially in the application of closed anti-rolling tanks. The traditional system relies on the inflow and outflow of seawater, and it is difficult to accurately control the liquid level in the water tank during navigation. In addition, the liquid level adjustment method in the existing technology usually requires manual intervention or simple mechanical devices, which causes the liquid level in the water tank to change slowly and cannot quickly adapt to changes in sea conditions, thereby affecting the anti-rolling effect. In order to improve the stability and navigation safety of the ship, there is an urgent need for a ship anti-rolling device that can accurately adjust the liquid level and efficiently control the distribution of liquid in the water tank, so as to adjust the rolling state of the ship in real time during navigation. Summary of the invention

This solution realizes fast and accurate liquid level adjustment through the configuration of the main water tank and the water storage tank, combined with multiple two-way water pumps, a liquid level detection system and a control system, so as to improve the ship's anti-roll effect. Multiple water pumps can speed up liquid transfer, ensure rapid response to changes in sea conditions, and optimize stability. It is particularly suitable for closed anti-roll water tanks, effectively avoiding seawater restrictions and extending the service life of the main water tank and the water storage tank. By pre-adjusting the water volume in the water storage tank, it can adapt to different loads and increase the flexibility of the ship. The baffle ensures the stability of the liquid in the water storage tank to avoid shaking interfering with the anti-roll effect.

[0022] The present invention will be further described in detail below with reference to the drawings and embodiments: As Figure 1-2 shown, a ship rolling resistance device includes a main water tank 1, a water storage tank 2, a water pump assembly, a liquid level detection assembly and a control system. The main water tank 1 is installed inside the hull, the water storage tank 2 is installed inside the hull and is located on one side of the main water tank 1. The water pump assembly is arranged between the main water tank 1 and the water storage tank 2. The inner cavities of the main water tank 1 and the water storage tank 2 are connected and communicated through the water pump assembly. The liquid level detection assembly includes a first liquid level gauge and a second liquid level gauge. The first liquid level gauge and the second liquid level gauge are respectively connected to the inside of the main water tank 1 and the water storage tank 2. The control system includes a signal acquisition module, a logic processing module and a drive execution module. The first liquid level gauge and the second liquid level gauge are both connected to the signal acquisition module.

[0023] The working principle of the anti-rolling water tank is based on the inertial effect of the liquid. It uses the mass and flow characteristics of the water body to reduce the rolling of the ship. When the ship is affected by external waves or wind, the hull will sway. The liquid in the anti-rolling water tank will flow accordingly according to the tilt and sway of the hull, thereby generating a reverse moment to offset the swaying force of the hull. By adjusting the quantity, position, and flow mode of the liquid in the water tank, the swaying amplitude of the hull can be effectively controlled, enhancing the stability of the ship.

[0024] The main purpose of adjusting the liquid level height of the anti-rolling water tank during navigation is to cope with the changes in the ship's rolling under different sea conditions. When the ship encounters the influence of different waves or wind, the rolling frequency and amplitude of the hull will change. Therefore, it is necessary to dynamically adjust the liquid level of the anti-rolling water tank to achieve the best anti-rolling effect. By adjusting the quantity and distribution of the liquid in the water tank, the inertial response of the water body can be adjusted so that a suitable reaction force is generated when the ship sways, thereby effectively reducing the swaying amplitude and improving the stability of the ship. In addition, the adjustment of the liquid level can also optimize the working state of the water tank according to the changes in the navigation speed and the weight of the hull, ensuring that the ship always maintains good stability and comfort under different sea conditions.

[0025] Traditional anti-rolling water tanks rely on the inflow and outflow of seawater, and it is relatively difficult to accurately control the liquid level of the water tank during navigation. Moreover, the liquid level adjustment method usually requires manual intervention or simple mechanical devices, resulting in a slow change in the liquid level of the water tank and being unable to quickly adapt to changes in sea conditions, thereby affecting the anti-rolling effect.

[0026] In this solution, a storage water tank 2 is innovatively added to the traditional anti-rolling water tank structure. The storage water tank 2 stores the liquid used to balance the hull inside the main water tank 1. By using the water pump assembly to introduce or extract the liquid in the storage water tank 2 into or out of the inside of the main water tank 1, the liquid level height inside the main water tank 1 can be quickly changed, thus adapting to different sea conditions. With the liquid level monitoring system, the liquid level change of the main water tank 1 can be monitored in real time and dynamically adjusted, thereby ensuring that the liquid distribution inside the main water tank 1 is always in the best state. This precise liquid level adjustment can effectively cope with different sea conditions and navigation states, greatly improving the anti-rolling effect, reducing the ship's rolling amplitude, and enhancing the navigation stability and comfort.

[0027] This solution is particularly applicable to closed anti-rolling water tanks because the liquids in the main water tank 1 and the water storage tank 2 can both be set as pre-stored fresh water or treated liquids, and there is no need to exchange with seawater during the water filling and drainage process, thus avoiding the corrosion of the inner cavities of the main water tank 1 and the water storage tank 2 by seawater, effectively extending the service life of the main water tank 1 and the water storage tank 2. Moreover, compared with the traditional seawater inlet and outlet method, this solution can achieve more rapid liquid level adjustment by pumping or injecting fresh water in the water storage tank, reducing the response time, which means that the ship can respond more quickly to external wave changes, ensuring that the anti-rolling system is always in the best working state, thereby enhancing the navigation safety and efficiency of the ship.

[0028] Since this solution can pre-adjust the water volume in the water storage tank 2, appropriate liquid adjustment can be made according to the total weight of the ship before departure. This design can not only optimize the center of gravity of the ship, but also adapt to the navigation requirements under different load conditions, increasing the load flexibility of the ship and improving the navigation stability.

[0029] The water pump assembly includes at least two two-way water pumps 3, and the two-way water pumps 3 are connected to the pipeline between the main water tank 1 and the water storage tank 2.

[0030] In this solution, by paralleling multiple two-way water pumps 3, water can be pumped from multiple positions and multiple channels simultaneously, thereby accelerating the transfer of water volume and the adjustment of liquid level. Compared with the pumping speed of a single water pump, a more rapid liquid level change can be achieved, ensuring that it can quickly respond to external factors such as waves or ship inclination when needed, maintaining the efficient operation of the anti-rolling system. At the same time, the load is shared by multiple two-way water pumps 3, ensuring that even if a certain water pump fails, other water pumps can still continue to work, thus guaranteeing the continuous operation of the anti-rolling system.

[0031] The two-way water pump 3 is connected to the drive execution module.

[0032] In this solution, when the liquid level detection component detects that the liquid level of the main water tank 1 does not meet the requirements, the signal acquisition module transmits the liquid level data to the drive execution module. According to the need of the liquid level, the drive execution module judges whether to start or stop the two-way water pump 3 according to the preset control logic. The drive execution module drives the two-way water pump 3 to start through an electric control signal, or adjusts the working states of multiple water pumps according to the system needs to ensure that the liquid can be transferred quickly and efficiently, achieving the purpose of precisely adjusting the liquid level of the main water tank 1. This automatic control mechanism enables the water pump to respond in real time to the liquid level changes of the ship, ensuring the stability and response speed of the anti-rolling system.

[0033] Such as Figure 3-4As shown, the interior of the water storage tank 2 is provided with a baffle 6 matching the shape of the inner cavity, and a hydraulic cylinder 5 is connected to the top of the water storage tank 2, the output end of the hydraulic cylinder 5 is connected to the baffle 6, the baffle 6 is placed horizontally, the hydraulic cylinder 5 is connected to the drive execution module, and a plurality of exhaust holes 7 are opened on the baffle 6.

[0034] In this solution, when the liquid level detection component detects the change of the liquid level in the water storage tank 2, the signal acquisition module transmits the data to the control system. The control system determines whether the position of the baffle 6 needs to be adjusted according to the preset logic. The drive execution module starts the hydraulic cylinder 5 according to the control signal. The hydraulic cylinder 5 drives the baffle 6 to be raised and lowered in the water storage tank 2 to keep the baffle 6 pressed on the liquid surface in the water storage tank 2. The function of the baffle 6 is to prevent unnecessary shaking of the liquid in the water storage tank 2 by pressing the liquid surface in real time, thereby ensuring the stability of the liquid in the water storage tank 2, avoiding the influence of liquid fluctuations on the anti-rolling effect, helping to maintain the stability of the ship and optimize the anti-rolling performance. The opening of the exhaust hole 7 helps the gas circulation on the upper and lower sides of the baffle 6 during its movement, thereby improving the stability of the movement of the baffle 6.

[0035] The main water tank 1 and the water storage tank 2 are both located in the longitudinal middle section of the hull.

[0036] The middle area of ​​the hull is usually the most stable part of the ship. Setting the main water tank 1 and the water storage tank 2 at this position can ensure that the distribution of the liquid in the water tank will not excessively affect the center of gravity of the ship, avoiding the tilting of the hull or the decrease in stability due to uneven distribution of liquid. In addition, the water tank in the middle area can effectively balance the rolling moment of the ship, reduce the violent shaking of the ship in the waves, and enhance the anti-rolling effect. Through this layout, the ship can better cope with various sea conditions during navigation and improve the overall navigation stability and safety.

[0037] A water injection pipe 4 is connected to the bottom of the outer end of the water storage tank 2, one end of the water injection pipe 4 is connected to the inner cavity of the water storage tank 2, and the other end of the water injection pipe 4 extends to the upper part of the hull deck. The water injection pipe 4 is a rigid closed structure, and a detachable sealing cover is connected to the water injection port of the water injection pipe 4. The main water tank 1 and the water storage tank 2 are both sealed structures, and the outer walls are made of high-strength corrosion-resistant materials.

[0038] In the present solution, the water injection section of the water injection pipe 4 is connected to the hull deck, so that fresh water can be injected into the water storage tank 2 through the pipe before sailing or under certain circumstances, so as to adjust the liquid level according to the weight of the ship and the navigation status. Through this design, the ship can conveniently adjust the water volume of the water storage tank 2 during navigation without directly relying on seawater. It is particularly suitable for closed anti-rolling tanks. The use of the water injection pipe 4 improves the flexibility of liquid regulation and can ensure that the water storage tank 2 is replenished with water in time.

It should be noted that for those skilled in the art, without departing from the technical solutions of the present invention, several modifications and improvements can be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
