Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of container ship side passage bilge water discharge, and particularly relates to a container ship side passage bilge water discharge system and method. BACKGROUND

[0002] The passage under the main deck of a container ship may have accumulated water under special conditions, and a water discharge solution needs to be considered. The current conventional design solution is to use a bilge pump in the engine room to discharge the accumulated water.

[0003] The accumulated water discharge solution used in the prior art has the following defects:

[0004] Conventional solution one is to connect the bilge water pipes of the left and right side passages of the container ship, which requires a 200-meter-long discharge pipe to be arranged in the side passage, connected to the bilge pump in the engine room, and the long pipe has large resistance and weight. Meanwhile, two crew members are needed to operate, one to start the discharge pump in the engine room and the other to open the discharge valve in the side passage.

[0005] Conventional solution two is to discharge the bilge water in the side passage bilge well to the nearest cargo bilge well by gravity, and the pipe needs to pass through the side ballast tank. The pipe layout is strictly subject to the overall damage calculation, which is not conducive to the pipe layout and later maintenance of the ship.

[0006] Therefore, to solve the above problems, the present application provides a container ship side passage bilge water discharge system and method which can reduce the length of the discharge pipe and facilitate operation. SUMMARY

[0007] To solve the above technical problems of the existing container ship side passage bilge water discharge, the present application provides a container ship side passage bilge water discharge system and method.

[0008] According to one object of the present application, the present application provides a container ship side passage bilge water discharge system, comprising an intake pipe arranged in a side passage bilge well, and an intake interface arranged at one end of the intake pipe.

[0014] Preferably, the suction interface and the discharge interface are arranged in the side passage.

[0015] Preferably, the end of the branch pipe away from the drain pipe is provided with the discharge interface, the end of the suction pipe away from the bilge well is provided with the suction interface, the discharge interface and the suction interface are oppositely arranged, and a region for arranging the portable pump is reserved between the discharge interface and the suction interface.

[0016] Preferably, the branch pipe and the suction pipe are flush with each other.

[0017] Preferably, blind flanges are arranged on the suction interface and the discharge interface, and inlet flanges and outlet flanges are arranged on the portable pump, the inlet flanges and the outlet flanges correspond to the flange interfaces on the blind flanges, respectively.

[0018] Preferably, the portable pump is a portable pneumatic diaphragm pump.

[0019] Preferably, a high-level alarm is arranged in the bilge well, and the high-level alarm is configured to send an alarm when the liquid level of the bilge well reaches a preset liquid level.

[0020] A method comprising the container ship side passage bilge water discharge system, and the method comprises the following steps:

[0021] S1. Monitoring the liquid level of the bilge water in the side passage bilge well, wherein;

[0022] S2. When it is monitored that the liquid level reaches a preset liquid level, an alarm signal is generated;

[0023] S3. In response to the alarm signal, the suction interface and the discharge interface are opened, the inlet of the portable pump is connected to the suction interface, and the outlet of the portable pump is connected to the discharge interface;

[0024] S4. Starting the portable pump to perform the drainage operation.

[0025] Compared with the prior art, the beneficial effects of the present application are:

[0026] The container ship side passage bilge water discharge system is simple to operate, uses the original deck drain pipe on the ship as the side passage drainage pipe, and cooperates with the portable pump to perform drainage.

[0027] Compared to existing technologies, this new technology eliminates the need for a main pipe connecting the bilge water pipes of the port and starboard side passages of a container ship. This simplifies the treatment of bilge water in each passage and allows for the connection and disconnection of pipes using only necessary shut-off valves, check valves, and blind flanges, thereby reducing pipe weight and resistance caused by excessively long pipes.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0029] Figure 1 This is a schematic diagram of a container ship side passage bilge water drainage system according to the present invention. Detailed Implementation

[0030] The following description is intended to provide a detailed account of the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0031] Please see Figure 1 This invention provides a technical solution: a container ship side passage bilge water drainage system, comprising:

[0032] The suction pipe 3 is installed in the side channel sewage well, and the end of the suction pipe 3 is provided with an openable and closable suction port 31.

[0033] The discharge pipe is led out from the downpipe of the open deck, and the end of the discharge pipe is provided with an openable and closable discharge port 81.

[0034] The discharge port 81 and the suction port 31 are configured to be temporarily connected via the portable pump 4.

[0035] The container ship side passage bilge water drainage system utilizes the ship's existing deck downpipes as side passage drainage pipes, and uses portable pumps for drainage. Compared with existing technologies, it eliminates the main pipe connecting the bilge water pipes of the sludge wells of the left and right side passages of the container ship, simplifies the treatment of bilge water in each side passage, and can control the connection between pipes through portable pumps, reducing pipe weight and the resistance caused by excessively long pipes.

[0036] Furthermore, both the suction port 31 and the discharge port 81 are located within the side channel to facilitate operation of both ports during use. In other embodiments, the suction port 31 and / or the discharge port 81 may also be located outside the side channel. In this embodiment, see [link to relevant documentation]. Figure 1 The sewage well is the sewage well in the port side passage.

[0037] Furthermore, the suction pipe 3 is equipped with a suction check valve 1 and a shut-off valve 2. Specifically, the suction check valve 1 is located at the end of the suction pipe 3 that connects to the sewage well. By adding a check valve to the suction pipe 3, the backflow of the medium when the pump stops can be effectively prevented, protecting the portable pump equipment from impact damage. In addition, the check valve can prevent impurities in the bilge water from directly contacting the shut-off valve 2, ensuring the sealing reliability and service life of the shut-off valve 2, and reducing maintenance requirements. By limiting the positions of the suction check valve 1 and the shut-off valve 2 on the suction pipe 3, the two valve bodies can together form a safe, reliable, and easy-to-maintain drainage system.

[0038] Furthermore, the discharge pipeline includes:

[0039] A downpipe 6 connects to the open deck, and this downpipe 6 is an integral part of the open deck. A branch pipe 8 extends from the downpipe 6, meaning the downpipe 6 and the branch pipe 8 are interconnected. A discharge check valve 5 is installed on the branch pipe 8, and the end of the branch pipe 8 is the discharge port 81. The discharge check valve 5 is an important safety design feature. Its function is to isolate the downpipe 6 of the open deck and prevent external seawater, rainwater, etc., from flowing back into the side passage or cargo hold area through the downpipe under any circumstances. The discharge check valve 5 and the suction check valve 1 are located on both sides of the portable pump, working together to ensure the safety, reliability, and convenience of drainage operations.

[0040] Furthermore, the branch pipe 8 has a discharge port 81 at the end opposite to the drain pipe 6, and the suction pipe 3 has a suction port 31 at the end opposite to the sewage well. The discharge port 81 and the suction port 31 are both spaced apart on the inner side of the side channel, with a reserved area between them for accommodating the portable pump 4. Even further, the branch pipe 8 and the suction pipe 3 are flush with each other. By defining the positions of the suction port 31 and the discharge port 81 within the side channel, and by specifying the arrangement of the branch pipe 8 and the suction pipe 3, it is convenient to temporarily connect the two ports using the portable pump 4.

[0041] In this embodiment, both the suction port 31 and the discharge port 81 are provided with blind flanges 7, and the portable pump 4 is provided with an inlet flange and an outlet flange, which correspond to the flange interfaces on the blind flange 7, respectively. When connecting the portable pump 4, the blind plate on the blind flange 7 is removed to expose the through hole for connecting the flange on the portable pump 4. Specifically, the installation of the portable pump 4 includes the following steps:

[0042] S1. Remove the blind plate of the blind flange 7 on the discharge port 81 and the suction port 31 to expose the flange interface of the blind flange 7;

[0043] S2. Connect the inlet flange on the portable pump 4 to the flange interface on the suction port 31, and connect the outlet flange on the portable pump 4 to the flange interface of the discharge pipeline.

[0044] S3. Open the shut-off valve 2 on the suction pipe 3 and start the portable pump 4. Under the suction of the pump, the bilge water flows through the suction pipe 3, the portable pump 4, and the discharge pipe in sequence, and finally flows into the open deck downpipe 6 to be discharged overboard.

[0045] S4. After drainage is completed, stop the portable pump 4, close the shut-off valve 2, disassemble the flange connection on the portable pump 4, reinstall the blind flange and tighten it on the blind flange 7.

[0046] Preferably, the portable pump 4 is a portable pneumatic diaphragm pump.

[0047] Furthermore, a high-level alarm is installed inside the sludge well, configured to sound an alarm when the bilge water level inside the sludge well reaches a preset level. In use, the operator can obtain the bilge water level inside the sludge well based on the alarm signal from the high-level alarm. When the bilge water level reaches the preset level, a portable pump 4 connects the suction pipe 3 and the discharge pipe, discharging the bilge water from the sludge well through the discharge pipe into the deck drain pipe 6, thereby draining it overboard.

[0048] Based on the aforementioned container ship side passage bilge water drainage system, a method is also provided, comprising the following steps:

[0049] S1. Monitor the bilge water level in the sewage well of the side passage;

[0050] S2. When the liquid level is detected to have reached the preset level, an alarm signal is generated;

[0051] S3. In response to the alarm signal, open the suction port 31 and the discharge port 81, connect the inlet of the portable pump 4 to the suction port 31, and connect the outlet of the portable pump 4 to the discharge port 81;

[0052] S4. Open the shut-off valve 2 on the suction line 3 and start the portable pump 4 to perform drainage operation.

[0053] As can be seen, the above method can be used to drain water from the bilge of container ships using only one crew member.

[0054] Compared to the conventional approach of connecting the bilge water pipes of the sewage wells on both sides of the container ship, which has a total length of over 200m and is connected to the daily bilge pump in the engine room, this container ship side passage bilge water drainage system and method eliminates the need for an excessively long main pipe.

[0055] Compared to another conventional solution, which involves draining the bilge water from the side passage septic tanks to the nearest cargo hold septic tank by gravity, the pipelines need to pass through the side ballast tanks. The pipeline routing is strictly constrained by the overall damage calculation, which is not conducive to the layout of the ship's piping system and subsequent maintenance. This container ship side passage bilge water drainage system and method is simple to lay out and convenient to operate and maintain.

[0056] In summary, the container ship side passage bilge water drainage system and method utilizes the ship's existing deck downpipe 6 as the side passage drainage pipe, and uses a portable pump 4 for drainage.

[0057] Compared to existing technologies, the main pipe connecting the bilge water pipes of the port and starboard side passages of the container ship is eliminated, simplifying the treatment of bilge water in each side passage. The connection and disconnection of the pipes can be achieved using only the necessary shut-off valve 2, check valve and blind flange 7, reducing the weight of the pipes and the resistance caused by excessively long pipes.

[0058] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in the present invention still fall within the patent scope of the present invention.
