Description

Technical Field

[0001] The present application relates to the field of ship anti-roll technology, and in particular to a ship anti-roll device. Background Art

[0002] In ship transportation, especially in the design of cargo holds involving car ro-ro ships and passenger ro-ro ships, the drainage system plays a vital role. The vehicle compartments of these ships are usually equipped with drain pipes or drainage pumps, which are designed to effectively remove water from the cargo holds to avoid many problems caused by water accumulation. First of all, water accumulation will increase the weight of the ship, which may cause overloading or affect the buoyancy of the ship, thereby affecting the draft of the ship. If the draft of the ship exceeds the design range, it may affect the navigation stability and safety of the ship. Water accumulation may also cause the center of gravity of the ship to increase, thereby causing the ship to roll or list. The position of the center of gravity of the ship is crucial to the stability of the ship. A center of gravity that is too high or too low will have a negative impact on the maneuverability and stability of the ship.

[0003] In design, the bottom of the vehicle hold of a ship is generally slightly higher than the water surface, which is conducive to the normal operation of the drainage system. In addition, in addition to the drainage system being used to remove accumulated water, it can also be used for spraying firefighting or general flushing operations. In these cases, water can be pumped out by starting the drainage pump to ensure the cleanliness and safety of the cargo hold.

[0004] With regard to the above-mentioned related technologies, the inventor believes that the bottom cargo hold is generally equipped with more and larger sewage wells and larger diameter discharge pipes, double sets of discharge pumps, etc., to prevent excessive water spraying from causing untimely drainage and increasing the total amount when fire water or sprinkler systems are needed in case of fire. In particular, when the free liquid surface on the deck is too large, the ship rolls, causing water to accumulate on one side of the ship, causing the ship to capsize. When the hull is sprayed, the drainage system is not draining smoothly, resulting in high water accumulation in the bottom garage. If this occurs during navigation, it will have a greater impact on the stability of the ship. Summary of the invention

[0005] In order to prevent water accumulation from sloshing and affecting the stability of the ship when spraying is required, and to reduce the impact on vehicle traffic when spraying is not required, the present application provides a ship anti-rolling device.

[0022] In ship transportation, especially in the design of cargo holds involving car ro-ro ships and passenger ro-ro ships, the drainage system plays a vital role. The vehicle compartments of these ships are usually equipped with drain pipes or drainage pumps, which are designed to effectively remove water from the cargo holds to avoid many problems caused by water accumulation. First of all, water accumulation will increase the weight of the ship, which may cause overloading or affect the buoyancy of the ship, thereby affecting the draft of the ship. If the draft of the ship exceeds the design range, it may affect the navigation stability and safety of the ship. Water accumulation may also cause the center of gravity of the ship to increase, thereby causing the ship to roll or list. The position of the center of gravity of the ship is crucial to the stability of the ship. A center of gravity that is too high or too low will have a negative impact on the maneuverability and stability of the ship.

[0023] In design, the bottom of the vehicle hold of a ship is generally slightly higher than the water surface, which is conducive to the normal operation of the drainage system. In addition, in addition to the drainage system being used to remove accumulated water, it can also be used for spraying firefighting or general flushing operations. In these cases, water can be pumped out by starting the drainage pump to ensure the cleanliness and safety of the cargo hold.

[0024] With regard to the above-mentioned related technologies, the inventor believes that the bottom cargo hold is generally equipped with more and larger sewage wells and larger diameter discharge pipes, double sets of discharge pumps, etc., to prevent excessive water spraying from causing untimely drainage and increasing the total amount when fire water or sprinkler systems are needed in case of fire. In particular, when the free liquid surface on the deck is too large, the ship rolls, causing water to accumulate on one side of the ship, causing the ship to capsize. When the hull is sprayed, the drainage system is not draining smoothly, resulting in high water accumulation in the bottom garage. If this occurs during navigation, it will have a greater impact on the stability of the ship.

[0025] In order to prevent water accumulation from sloshing and affecting the stability of the ship when spraying is required, and to reduce the impact on vehicle traffic when spraying is not required, the present application provides a ship anti-rolling device.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The present application embodiment discloses a ship anti-heeling device. Figure 1 , Figure 2 A ship anti-rolling device includes a hull bottom plate 1, which is a horizontally arranged plate structure. Hull side plates 2 are arranged around the hull bottom plate 1, and the hull side plates 2 are vertically arranged. The hull side plates 2 are fixedly connected to the hull bottom plate 1, and a closed hull structure is formed by the hull bottom plate 1 and the hull side plates 2.

[0030] A partition plate 3 is hingedly provided on the hull bottom plate 1, and a flip assembly is provided on one side of the partition plate 3. The flip assembly can drive the partition plate 3 to rotate, and in some embodiments, the flip angle range of the partition plate 3 is 0°-90°. By flipping the partition plate 3, the partition plate 3 is in a vertical state, and the interior of the hull structure is separated by the partition plate 3, and the liquid in each separated area is separated, which can effectively reduce the risk of rolling during the navigation of the ship and improve the navigation safety of the ship.

[0031] The end walls of both ends of the partition board 3 are fixedly connected to one side close to the hull side plate 2. In some embodiments, the seal may be a rubber structure, one side of the seal is fixedly connected to the side wall of the partition board 3, and the other side of the seal abuts against and slides relatively with the side wall of the hull side plate 2, and the seal completely wraps the side wall of the partition board 3. Therefore, the gap between the partition board 3 and the hull side wall can be reduced by the provided seal.

[0032] In some embodiments, the flip assembly includes a hydraulic cylinder 4, the cylinder end of the hydraulic cylinder 4 is hinged to the hull bottom plate 1, and the piston end of the hydraulic cylinder 4 is hinged to the side wall of the partition plate 3. When the piston rod of the hydraulic cylinder 4 is retracted into the hydraulic cylinder 4, the hydraulic cylinder 4 drives the partition plate 3 to be placed horizontally. At this time, the partition plate 3 is used as a passage to avoid affecting the passage of vehicles inside the hull. When the piston rod of the hydraulic cylinder 4 is fully extended, the hydraulic cylinder 4 drives the partition plate 3 to be placed vertically. At this time, when the partition plate 3 is used as a partition to prevent excessive water accumulation, the flow effect of the accumulated water is poor, affecting the stability of the ship.

[0033] Reference Figure 3In some embodiments, a hidden groove 31 is opened on one side of the partition plate 3 close to the hydraulic cylinder 4. The hidden groove 31 is arranged opposite to the hydraulic cylinder 4, and when the partition plate 3 is in a horizontal state, the hydraulic cylinder 4 is completely located inside the hidden groove 31.

[0034] Reference Figure 4 In some embodiments, a receiving groove 11 is provided on the hull bottom plate 1 at a position relative to the partition plate 3, and the end of the partition plate 3 is located inside the receiving groove 11 and is relatively hinged. The groove depth of the receiving groove 11 is the same as the thickness of the partition plate 3, so that when the partition plate 3 is in a horizontal state, the partition plate 3 is completely located inside the receiving groove 11, and the top wall of the partition plate 3 is flush with the surface of the hull bottom plate 1.

[0035] In some embodiments, the partition plate 3 includes an action surface 32 close to one side of the hydraulic cylinder 4 and an articulated surface 33 hingedly arranged with the hull bottom plate 1, the action surface 32 and the articulated surface 33 are arranged vertically, and the hinge point between the partition plate 3 and the hull bottom plate 1 is located on the side of the articulated surface 33 close to the action surface 32. The articulated surface 33 is a planar structure arranged vertically relative to the action surface 32, so that when the partition plate 3 is in a vertical state, the articulated surface 33 can be relatively stably abutted with the hull bottom plate 1.

[0036] In some embodiments, a plurality of partition plates 3 are provided on the hull bottom plate 1, and the plurality of partition plates 3 divide the interior of the hull into a plurality of relatively isolated spaces, thereby isolating the accumulated water inside the plurality of independent spaces.

[0037] The implementation principle of a ship anti-roll device in an embodiment of the present application is as follows: a movable partition board 3 is set below the waterline or in the middle of the garage above, and the partition board 3 can be erected or laid flat on the deck through a hydraulic cylinder 4. When the ship is sailing, the partition board 3 is erected to prevent excessive water accumulation from flowing to the general state and affecting the stability of the ship.

[0038] When the ship docks, the partition board 3 is lowered to serve as a passage to avoid affecting the passage of vehicles.
