Description

Technical Field

[0001] The invention relates to the technical field of wave-proof protective covers, in particular to a wave-proof protective cover for a main deck side pump. Background Art

[0002] Oil tankers refer to "ships" that carry oil and oil products (such as diesel, gasoline and heavy oil, etc.). Its structural features are: ① Oil pumps are used to load and unload cargo through pipelines, so there are no lifting equipment and large cargo hatches on the deck, but there are entry hatches. ② Since oil is easy to volatilize, burn and explode, strict fire safety requirements are imposed. The 1978 Protocol of the International Maritime Organization stipulates that new oil tankers with a deadweight of more than 20,000 tons must have inert gas explosion-proof facilities and the engine room must be located at the stern. ③ The cargo oil tanks are separated by multiple longitudinal bulkheads and multiple transverse bulkheads to reduce the impact of free liquid surface on stability. ④ The length-to-depth ratio of the hull is large, and the bending moment is large, so longitudinal frame structures are often used to increase longitudinal strength. ⑤ Transportation is often unidirectional. In order to maintain a certain draft when emptying on the return trip, a large amount of ballast water must be loaded, so modern large oil tankers must be equipped with dedicated ballast water tanks.

[0003] Some ballast pumps of oil and chemical ships are arranged on the side of the main deck, which is easily hit when the wind and waves are too strong while the ship is sailing. The ballast pump motor part exposed on the deck surface is easily damaged. The traditional protective cover is highly open, which will increase the failure rate of the ballast pump motor in some bad weather. Summary of the invention

[0038] Based on the first embodiment, this embodiment introduces a specific structure of the control component 12 used in the main deck side pump wave protection cover, such as Fig.10 As shown, the inner wall of the control tube 24 is fixedly connected to two slide rails 30, and the same rack 29 is slidably connected to the two slide rails 30, one end of the rack 29 is fixedly connected to the sealing seat 28, the inner wall of the control tube 24 is rotatably connected to a gear 2 31, and the gear 2 31 and the rack 29 are meshed with each other, one end of the transmission shaft of the gear 2 31 is sleeved with a volute spring 32, and the volute spring 32 is installed on the inner wall of the control tube 24, and the slide rail 30 in the control tube 24 is convenient for sliding installation of the rack 29, and when the rack 29 moves, it is convenient to drive the sealing seat 28 to move, and when the rack 29 moves, it directly drives the gear 2 31 to rotate, and when the gear 2 31 rotates, it directly drives the volute spring 32 to reel.

[0039] Working principle: When in use, the protective cover 1 is fixed on the deck of the ship, and then the ballast pump motor is fixed inside the protective cover 1. In normal weather, the inspection door 5 is in an open state, and the two ventilation components 2 are opened at the same time. When opened, the servo motor 35 starts to drive the gear three 34 to rotate. When the gear three 34 rotates, it directly drives the gear one 33 to rotate. When the gear one 33 rotates, it directly drives the mesh plate two 23 to rotate. When the meshes on the mesh plate two 23 and the mesh plate one 20 overlap, the air duct of the ventilation component 2 can be opened. At this time, the ballast pump motor is cooled through the relatively open protective cover 1; When the ship encounters bad weather during navigation, the inspection door 5 is directly closed. When the inspection door 5 is locked, the T-slot 13 on the connecting seat 6 is sleeved on the two L-shaped seats 17, and the rotating disk 18 is rotated at this time. When the rotating disk 18 rotates, it directly drives the two-way screw 15 to rotate. When the two-way screw 15 rotates, it directly drives the two driving seats 16 to move toward or away from each other. When the two driving seats 16 move away from each other, they directly drive the two L-shaped seats 17 to insert into the T-slot 13, so as to facilitate the fixing of the inspection door 5. At the same time, the holes on the mesh plate 1 20 and the mesh plate 2 23 in the two ventilation components 2 are staggered to close the air duct of the ventilation component 2. At the same time, the fan 10 in the exhaust mechanism 4 is started. When the fan 10 is started, the air in the protective cover 1 is discharged through the air duct 11, and the air in the air duct 11 is discharged through the control component 12. When the air pressure in the control tube 24 increases, the sealing seat 28 is directly pushed to open. At this time, the spring 27 is compressed. When the fan 10 stops, the spring 27 drives the sealing seat 28 to close the control tube 24, or drives the rack 29 to slide through the movement of the sealing seat 28. When the rack 29 slides, it directly drives the gear 2 32 to rotate, thereby winding the volute spring 32 thereon. When the fan 10 stops, the volute spring 32 returns to its original position and the sealing seat 28 closes the control tube 24.
