Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering, and particularly relates to a rapid transfer system for anti-heeling water tanks. Background Art

[0002] For a large lifting ship or a ship equipped with a full-rotation crane, when the heavy object being lifted turns from the stern to the side of the ship, the change in the center of gravity of the crane and the lifted weight will generate a lateral moment that changes with time, thereby causing the ship to heel. Therefore, a corresponding lateral load adjustment system needs to be set up to control the heeling of the ship by reversely transferring ballast water.

[0003] The design idea of the traditional heeling adjustment system, as shown in Figure 1 、 Figure 2 and Figure 3 respectively, sets several pairs of ballast tanks on both sides of the ship. A first two-way load transfer pump 100 is set and connected to the left load transfer water tank a and the right load transfer water tank b respectively through a load transfer pipeline 140, two groups of switching valves 110, and a first suction end 130. Specifically, both ends of the load transfer pipeline 140 are connected to the left load transfer water tank a and the right load transfer water tank b. The first two-way load transfer pump 100 is arranged in the middle of the load transfer pipeline 140. The two groups of switching valves 110 are located at both ends of the load transfer pipeline 140, and first suction ends 130 are arranged at both ends of the load transfer pipeline 140, that is, at the ends of the left load transfer water tank a and the right load transfer water tank b. During the lifting operation, the direction of transferring ballast water ( Figure 2 transferring from the starboard side to the port side, Figure 3 transferring from the port side to the starboard side) and the amount of transferred water are mainly determined by the heeling angle of the ship to control the heeling angle of the ship and ensure the ship operation.

[0004] However, the above traditional setting has the following limitations:

[0005] (1) The ballast water tanks on the left and right sides are set in pairs, and there is only one ballast tank on each side. As a result, the speed of transferring ballast water in each pair of ballast tanks is completely restricted by the displacement of the load transfer pump;

[0006] (2) For large ships or heavy loads with a fast rotation speed, it is often necessary to continuously increase the displacement of the load transfer pump to meet the need for quickly adjusting the ballast water, and the method is single;

[0007] (3) Due to the special impeller design of the two-way pump, it is difficult to select a load transfer pump with too large a displacement. Summary of the Utility Model

[0008] The technical problem to be solved by the utility model is: how to provide a rapid transfer system for anti-heeling water tanks to control the heeling angle of the ship.

[0009] To solve the above technical problem, the utility model provides the following technical solutions:

[0010] An anti-heeling water tank rapid transfer system, comprising:

[0011] An upper left ballast tank and a lower left ballast tank located on the left side;

[0012] An upper right ballast tank and a lower right ballast tank located on the right side;

[0013] A power transfer pipeline, with a two-way transfer pump installed in the middle of the power transfer pipeline. Both ends of the power transfer pipeline are divided into two power transfer branches. Among them, power transfer branch one is connected to the upper left ballast tank or the upper right ballast tank, and power transfer branch two is connected to the lower left ballast tank or the lower right ballast tank;

[0014] A gravity transfer pipeline, both ends of the gravity transfer pipeline are divided into two gravity transfer branches. Among them, gravity transfer branch one is connected to power transfer branch one, and gravity transfer branch two is connected to the lower left ballast tank or the lower right ballast tank.

[0015] In this application, the ballast water on the port side is divided into upper and lower tanks, namely the upper left ballast tank and the lower left ballast tank, and the ballast water on the starboard side is divided into upper and lower tanks, namely the upper right ballast tank and the lower right ballast tank. At the same time, a power transfer pipeline and a gravity transfer pipeline are set up. Through the innovative layout of the transfer tanks, while realizing the transfer by the anti-heeling pump, the gravity transfer of ballast water is achieved by using the height difference between the two sides of the ship's compartments, greatly improving the speed of transferring ballast water and quickly correcting the floating state of the ship to ensure the safety of operations.

[0016] As a further solution of the present utility model: Suction ends are provided at the ends of the power transfer branch one connected to the upper left ballast tank or the upper right ballast tank.

[0017] As a further solution of the present utility model: Suction ends are provided at the ends of the power transfer branch two connected to the lower left ballast tank or the lower right ballast tank.

[0018] As a further solution of the present utility model:

[0019] A seventh switch valve is provided on the power transfer branch one connected to the upper left ballast tank;

[0020] A fifth switch valve is provided on the power transfer branch one connected to the upper right ballast tank.

[0021] As a further solution of the present utility model:

[0022] An eighth switch valve is provided on the power transfer branch two connected to the lower left ballast tank;

[0023] A sixth switch valve is provided on the power transfer branch two connected to the lower right ballast tank.

[0024] As a further solution of the utility model:

[0025] A second switching valve and a third switching valve are respectively arranged on two gravity load adjustment branches one that are connected to the first power load adjustment branch.

[0026] As a further solution of the utility model:

[0027] A first switching valve is arranged on the second gravity load adjustment branch that is connected to the lower left load adjustment water tank;

[0028] A fourth switching valve is arranged on the second gravity load adjustment branch that is connected to the lower right load adjustment water tank.

[0029] As a further solution of the utility model:

[0030] When the bidirectional load adjustment pump transfers the ballast water in the lower right load adjustment water tank to the upper left load adjustment water tank through the power load adjustment pipeline, the ballast water in the upper right load adjustment water tank is transferred to the lower left load adjustment water tank through the gravity load adjustment pipeline.

[0031] As a further solution of the utility model:

[0032] When the bidirectional load adjustment pump transfers the ballast water in the lower left load adjustment water tank to the upper right load adjustment water tank through the power load adjustment pipeline, the ballast water in the upper left load adjustment water tank is transferred to the lower right load adjustment water tank through the gravity load adjustment pipeline.

[0033] As a further solution of the utility model: the upper left load adjustment water tank and the lower left load adjustment water tank are independently arranged; the upper right load adjustment water tank and the lower right load adjustment water tank are independently arranged.

[0034] Compared with the prior art, the beneficial effects of the utility model are:

[0035] Firstly, in this application, the port side load adjustment water is divided into upper and lower tanks, namely the upper left load adjustment water tank and the lower left load adjustment water tank, and the starboard side load adjustment water is divided into upper and lower tanks, namely the upper right load adjustment water tank and the lower right load adjustment water tank. At the same time, a power load adjustment pipeline and a gravity load adjustment pipeline are arranged. Through the innovative load adjustment tank layout, while realizing the load adjustment of the anti-heeling pump, the gravity transfer of ballast water is realized by using the height difference of the divided tanks on both sides, greatly improving the speed of transferring ballast water, quickly correcting the floating state of the ship, and ensuring the operation safety;

[0036] Secondly, in this application, the bidirectional load adjustment pump can transfer ballast water to the left or right according to needs. At the same time, combined with the gravity load adjustment pipeline, the cooperation of power transfer + gravity transfer is realized. Compared with the traditional single transfer system, this application can ensure better anti-heeling effect and higher stability of the ship. And with such a setting, the displacement of the load adjustment pump can be reduced or a faster transfer speed can be achieved with the same displacement;

[0037] Finally, the anti - heeling ballast tanks on the port side and starboard side of this application can alternately transfer water. While the transfer pump is transferring water, the water in the higher - level tank can be transferred to the lower - level tank on the other side, improving the operation efficiency. Moreover, while using the transfer pump to transfer water, gravity drainage adjustment is also utilized to achieve a greater transfer capacity, thereby achieving a better transfer effect.

It should be understood that this direction setting is only for convenience of description and understanding, and should not be construed as a limitation to the present invention.

[0058] Referring to Figure 4 , a power trimming pipeline 210 is provided between the trimming tanks on both sides. A two-way trimming pump 200 is installed in the middle of the power trimming pipeline 210. Both ends of the power trimming pipeline 210 are divided into two power trimming branches.
