[0002] At present, the structures of the underwater watertight hatch covers of the moonpools of domestic scientific research ships are such that the switch oil cylinders are buried in the frame structure and directly connected to the bolts to push the bolts to move back and forth. Once water enters the frame and submerges the oil cylinder, there is a risk of the oil cylinder being soaked. Especially for ships sailing in ice areas, icing may also occur, directly freezing the oil cylinder and preventing it from working properly. As a result, the large equipment system cannot be activated. The oil cylinder being soaked alternately for a long time will greatly shorten its life cycle. Summary of the Invention

[0023] An embodiment of the present invention provides a protection device for a moonpool oil cylinder, including: a moonpool cofferdam 1, a hatch cover body 2, an oil cylinder 3, a liquid level telemetry probe 4, a console panel 5, a suction port 6, a bilge water pipeline 7, and a bilge fire pump 8.

[0024] Each partition structure and the surrounding plate of the hatch cover body 1 are drilled with drain holes 11, and the position of the drain holes 11 is lower than the bottom surface 31 of the oil cylinder 3. When the sea hatch of the ship leaks and water enters the hatch, the water is drained into the moonpool cofferdam 1 through the drain holes 11.

[0025] A liquid level telemetry probe 4 is arranged at the stern corner of the moonpool cofferdam 1, and the alarm point of the liquid level telemetry probe 4 is set lower than the bottom surface 31 of the oil cylinder 3.

[0026] The liquid level telemetry probe 4 is connected to the console panel 5, and the console panel 5 is connected to the suction port 6, the bilge water pipeline 7, and the bilge fire pump 8.

[0027] In some embodiments, the alarm point of the liquid level telemetry probe 4 is set lower than the bottom surface 31 of the oil cylinder 3, including: the alarm point of the liquid level telemetry probe 4 is set at about 20 mm lower than the bottom surface 31 of the oil cylinder 3.

[0028] In some embodiments, the number of the drain holes 11 is plural.

[0029] In some embodiments, the suction port 6 is connected to the bilge fire pump 8 through the bilge water pipeline 7, and the bilge fire pump 8 is used to drive the suction port 6 to pump out the water in the moonpool cofferdam 1 through the bilge water pipeline 7.

[0031] In some embodiments, the moonpool cofferdam 1 is used to hold the water drained through the drain holes 11.

[0032] In some embodiments, the oil cylinder 3 is arranged in the moonpool cofferdam 1, and the liquid level telemetry probe 4 is used to detect the liquid level height in the moonpool cofferdam 1 and send an alarm signal to the console panel 5 when the liquid level height is higher than the preset alarm threshold.

[0033] In some embodiments, a valve 71 is provided in the bilge water pipeline 7, and the valve 71 is used to control the water flow of the suction port 6 and the bilge water pipeline 7.

[0034] For the moonpool oil cylinder protection device provided in the above embodiments of the present application, by directly introducing the water in the hatch cover frame into the moonpool well 1, and arranging a liquid level telemetry probe 4 lower than the height of the oil cylinder 3 at the stern-tilting structure in the moonpool well 1, and simultaneously arranging a suction port 6 to access the bilge water system, the problem that the oil cylinder 3 will not be damaged and the equipment cannot be used due to freezing once water leaks into the ship's hatch cover is solved. In the case where a ship with a watertight hatch cover leaks water and cannot return to the dock for repair in a short time, the crew of this invention patent can discover and activate the device in the first time, so that the equipment oil cylinder will not be damaged or frozen and unable to work. It ensures the normal function of the ship equipment in case of water leakage.

[0035] The moonpool oil cylinder protection device of some embodiments of the present invention is composed of a moonpool well, a hatch cover body structure, an oil cylinder, a liquid level telemetry probe, a console panel, a suction port and a bilge water pipeline, and a bilge fire pump.

[0036] Drainage holes are drilled on each partition plate structure and the surrounding plate of the hatch cover body. The drainage hole drilling position must be lower than the bottom surface of the oil cylinder. When water leaks into the moonpool hatch cover due to the leakage of the ship's watertight hatch cover, the water is drained into the moonpool well structure through a plurality of drainage holes.

[0037] A liquid level telemetry probe is arranged at the stern corner of the moonpool well, and the alarm point is set about 20 mm lower than the bottom surface of the oil cylinder. When the water stored in the moonpool structure reaches a certain liquid level, the sensor of the liquid level telemetry probe is triggered, and it is transmitted to the console panel in the superstructure control room to issue an alarm, so that the crew can know the ship's water intake status and make timely responses.

[0038] After receiving the console alarm signal, the crew opens the fire pump and the valve on the pipeline, starts the suction port to automatically complete the water suction action, so that the surrounding liquid level where the oil cylinder is located drops to a safe value, thus protecting the oil cylinder from being soaked in water and freezing in the ice area.

[0039] The moonpool oil cylinder protection device of the embodiments of the present application can be used on polar research vessels, solves the related technical problems of damage to the oil cylinder and inability to use the equipment due to freezing once water leaks into the ship's hatch cover, and extends the service life of the equipment where the oil cylinder is located. It ensures the normal operation of the underwater hatch cover system of the ship when sailing in the ice area. The moonpool can implement the normal deployment of relevant scientific research equipment in the ice area and deep sea, sample relevant scientific research data for research institutes to develop relevant topics, and provides sufficient reference and guidance for the corresponding treatment measures for the problem of long-term immersion or freezing of the oil cylinder caused by water leakage of the ship's hatch cover in the industry.

[0040] Among the technical solutions described in the embodiments of the present application, any combination is possible without conflict.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claimed rights.
