Description

Technical Field

[0001] This utility model relates to the technical field of hatch cover sealing structure, specifically a leak-proof sealing structure for a marine hatch cover. Background Technology

[0002] A ship is a man-made means of transportation that primarily operates in water. Civilian ships are generally called boats, military ships are called warships, and small boats are called vessels or dinghies; collectively, they are called ships or dinghies. Internally, a ship mainly includes living space, supporting structures, and drainage structures, and has a propulsion system that utilizes external or internal energy. Ship compartments refer to all enclosed spaces separated by longitudinal and transverse bulkheads and decks. They can generally be divided into three main categories: crew compartments, working compartments, and service compartments. Crew compartments include bedrooms, sanitary rooms, dining rooms, and meeting rooms, and should generally be located above the freeboard deck. Hatch covers require a sealing structure to ensure stability during use.

[0003] Traditional ship hatch cover sealing structures are typically quite simple, often consisting of only basic gaskets. These sealing materials may fail due to wear and tear or improper installation over long-term use. Furthermore, some traditional sealing structures may not account for the minute movements of the hatch cover during ship movement, making it prone to loosening during use and resulting in lower overall stability, thus allowing seawater to enter the cargo hold. Utility Model Content

[0004] The purpose of this utility model is to provide a leak-proof sealing structure for marine hatch covers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof sealing structure for a marine hatch cover, comprising a hatch access channel, a hatch cover rotatably connected to the top of the hatch access channel, and a compression sealing mechanism provided in the middle of the hatch cover;

[0006] The cabin access passage includes a passage body, a fixing ring is fixedly connected to the top of the passage body, and a rubber sealing groove is opened on the top of the fixing ring. The cabin cover includes a cabin cover body, and a rubber sealing ring is fixedly connected to the bottom of the cabin cover body.

[0007] Preferably, the compression sealing mechanism includes two threaded fasteners, which are fixedly connected to the hatch cover body by fixing bolts. The inner walls of the two threaded fasteners are threadedly connected to a threaded rotating rod, the outer wall of the threaded rotating rod is rotatably connected to the hatch cover body, and a fixing rod is fixedly connected to the bottom of the threaded rotating rod.

[0008] Preferably, a rotating handle is fixedly connected to the bottom of the fixed rod, a rotating handwheel is fixedly connected to the top of the threaded rotating rod, a threaded sleeve is fixedly connected to the bottom of the threaded rotating rod, a threaded rod is threadedly connected to the inner wall of the threaded sleeve, and the threaded rod is rotatably connected to the outer wall of the threaded fastener.

[0009] Preferably, a rotating disk is fixedly connected to the bottom of the threaded rod, and four fixing nails are fixedly connected to the top of the rotating disk. A connecting rod is rotatably connected to the outer wall of each of the four fixing nails, and an anti-slip sleeve is fitted onto the end of each of the four connecting rods away from the fixing nail.

[0010] Preferably, the top of each of the four connecting rods is provided with a sliding groove, the inner wall of each of the four sliding grooves is movably connected with a limiting rod, the top of each of the four limiting rods is fixedly connected to the hatch body, and the bottom of each of the four limiting rods is prevented from falling off by a fixing nut.

[0011] Preferably, the bottom of the rotating disk is fixedly connected to an unfolding handle, and the inner wall of the unfolding handle is rotatably connected to a fixed rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model proposes a leak-proof sealing structure for a marine hatch cover. The structure involves a hatch cover and a compression sealing mechanism connected via a hatch access passage. The closing mechanism involves a fixed ring and the hatch cover body. By rotating the handwheel, the threaded rotating rod and two threaded fixing parts move in a threaded motion, causing the threaded sleeve to rotate. This rotates the rotating disc until the limiting rod moves from one end of the sliding groove to the other. At this point, the anti-slip sleeve reaches the bottom of the fixed ring, preventing the rotating disc from rotating. The threaded rod then moves in a threaded motion along the inner wall of the threaded sleeve, gradually bringing the anti-slip sleeve into contact with the bottom of the fixed ring. This causes the limiting rod to pull the hatch cover body, compressing the fixed ring and causing the rubber sealing ring to engage with the inner wall of the rubber sealing groove. This achieves rapid closure and installation of the hatch cover while improving the sealing performance between the hatch cover and the hatch access passage. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see the appendix Figure 1-4 This application provides the following technical solutions.

[0021] A leak-proof sealing structure for a marine hatch cover includes a hatch access channel 1, a hatch cover 2 rotatably connected to the top of the hatch access channel 1, and a compression sealing mechanism 3 disposed in the middle of the hatch cover 2; the hatch access channel 1 includes a channel body 11, a fixing ring 12 fixedly connected to the top of the channel body 11, and a rubber sealing groove 13 formed on the top of the fixing ring 12; the hatch cover 2 includes a hatch cover body 21, a rubber sealing ring 22 fixedly connected to the bottom of the hatch cover body 21; the compression sealing mechanism 3 includes two threaded fasteners 31, which are connected to the hatch cover 2 by fixing bolts. The main body 21 is fixedly connected to the cover. The inner walls of the two threaded fasteners 31 are threadedly connected to a threaded rotating rod 32. The outer wall of the threaded rotating rod 32 is rotatably connected to the main body 21 of the cover. The bottom of the threaded rotating rod 32 is fixedly connected to a fixing rod 311. The bottom of the fixing rod 311 is fixedly connected to a rotating handle 312. The top of the threaded rotating rod 32 is fixedly connected to a rotating handwheel 33. The bottom of the threaded rotating rod 32 is fixedly connected to a threaded sleeve 34. The inner wall of the threaded sleeve 34 is threadedly connected to a threaded rod 35. The threaded rod 35 is rotatably connected to the outer wall of the threaded fastener 31.

[0022] It should be noted that if the operator is outside the cabin, rotate the hatch cover body 21 until it is in contact with the fixing ring 12, and then rotate the handwheel 33 to drive the threaded rotating rod 32 to rotate. The threaded rotating rod 32 moves with the threaded fixing part 31, causing the threaded rotating rod 32 to move on the inner wall of the threaded fixing part 31, driving the threaded sleeve 34 to rotate. The threaded sleeve 34 drives the internal threaded rod 35 to rotate, causing the limiting rod 310 to move the hatch cover body 21 downward, so that the hatch cover body 21 squeezes the top of the fixing ring 12, and the rubber sealing ring 22 is tightly inserted into the hatch cover body 21, realizing the quick closing and installation of the hatch cover 2, while improving the sealing between the hatch cover 2 and the cabin access passage 1.

[0023] A rotating disk 36 is fixedly connected to the bottom of the threaded rod 35. Four fixing nails 37 are fixedly connected to the top of the rotating disk 36. Connecting rods 38 are rotatably connected to the outer walls of the four fixing nails 37. Anti-slip sleeves 313 are fitted onto the ends of the four connecting rods 38 away from the fixing nails 37. Sliding grooves 39 are opened through the tops of the four connecting rods 38. Limiting rods 310 are movably connected to the inner walls of the four sliding grooves 39. The tops of the four limiting rods 310 are fixedly connected to the hatch body 21. The bottoms of the four limiting rods 310 are prevented from falling off by fixing nuts.

[0024] It should be noted that the threaded sleeve 34 drives the internal threaded rod 35 to rotate, which in turn drives the bottom rotating disk 36 to rotate. This causes the four fixing pins 37 to rotate around the rotating disk 36. The limiting rod 310 restricts the rotation of the four connecting rods 38 around the fixing pins 37. At the same time, the limiting rod 310 slides on the inner wall of the sliding groove 39, causing the four connecting rods 38 to extend in all directions until the anti-slip sleeve 313 reaches the bottom of the fixing ring 12. At this point, the rotating disk 36 cannot rotate due to the restriction of the limiting rod 310. This allows the threaded rod 35 to move in a threaded motion with the threaded sleeve 34. The threaded rod 35 moves within the inner wall of the threaded sleeve 34, driving the rotating disk 36 to move upward. The rotating disk 36 then drives the connecting rod 38 and the anti-slip sleeve 313 fixed at the top to move upward, causing the anti-slip sleeve 313 to fit against the bottom of the fixing ring 12. At this time, the fixing screw at the bottom of the limiting rod 310 prevents the limiting rod 310 from disengaging from the inner wall of the sliding groove 39, causing the limiting rod 310 to drive the hatch body 21 to move downward.

[0025] The bottom of the rotating disk 36 is fixedly connected to an unfolding handle 314. The inner wall of the unfolding handle 314 is rotatably connected to the fixed rod 311. When the unfolding handle 314 rotates, the limiting rod 310 can slide on the inner wall of the sliding groove 39, and the threaded rod 35 and the threaded sleeve 34 can perform threaded movements.

[0026] It should be noted that when the operator is inside the cabin, the rotating handle 314 can be turned to drive the rotating disk 36 to rotate. The rotating disk 36 drives the four connecting rods 38 to rotate around the fixing nail 37 until the anti-slip sleeve 313 reaches the bottom of the fixing ring 12. Then, by turning the rotating handle 312, the fixing rod 311 is driven to rotate, so that the threaded rotating rod 32 and the threaded fixing part 31 make threaded movement, so that the rotating disk 36 moves upward, causing the anti-slip sleeve 313 to fit against the bottom of the fixing ring 12, so that the limiting rod 310 drives the hatch cover body 21 to move downward, thereby achieving the closure and sealing of the hatch cover 2.

[0027] If the operator is outside the cabin, rotate the hatch body 21 until it aligns with the fixing ring 12, then rotate the handwheel 33 to rotate the threaded rotating rod 32. The threaded rotating rod 32 moves threadedly against the threaded fixing part 31, causing the threaded rotating rod 32 to move within the threaded fixing part 31, thus rotating the threaded sleeve 34. The threaded sleeve 34 then rotates the internal threaded rod 35, which in turn rotates the bottom rotating disk 36. This causes the four fixing pins 37 to rotate around the rotating disk 36. The limiting rod 310 restricts the rotation of the four connecting rods 38 around the fixing pins 37. As the device rotates, the limiting rod 310 slides on the inner wall of the sliding groove 39, causing the four connecting rods 38 to extend outwards until the anti-slip sleeve 313 reaches the bottom of the fixed ring 12. At this point, due to the restriction of the limiting rod 310, the rotating disk 36 cannot rotate, allowing the threaded rod 35 to perform threaded movement with the threaded sleeve 34. The threaded rod 35 moves on the inner wall of the threaded sleeve 34, driving the rotating disk 36 to move upwards. The rotating disk 36 then drives the connecting rods 38 and the anti-slip sleeve 313 fixed at the top to move upwards, causing the anti-slip sleeve 313 to fit against the bottom of the fixed ring 12. At this point, the limiting rod... The fixing screw at the bottom of 310 prevents the limiting rod 310 from disengaging from the inner wall of the sliding groove 39, causing the limiting rod 310 to move the hatch cover body 21 downwards. This causes the hatch cover body 21 to press against the top of the fixing ring 12, tightly engaging the rubber sealing ring 22 within the hatch cover body 21, achieving rapid closure and installation of the hatch cover 2. Simultaneously, this improves the sealing between the hatch cover 2 and the cabin access passage 1. When the operator is inside the cabin, rotating the unfolding handle 314 rotates the rotating disk 36, which in turn rotates the four connecting rods 38 around the fixing pin 37. Simultaneously, the limiting rod 310... Sliding along the inner wall of the sliding groove 39, the four connecting rods 38 extend outwards until the anti-slip sleeve 313 reaches the bottom of the fixing ring 12. At this point, the fixing rod 311 can be rotated by rotating the rotating handle 312, causing the threaded rotating rod 32 and the threaded fixing part 31 to make threaded movement, causing the rotating disk 36 to move upwards, causing the anti-slip sleeve 313 to fit against the bottom of the fixing ring 12, causing the limiting rod 310 to move the hatch cover body 21 downwards, causing the hatch cover body 21 to press against the top of the fixing ring 12, causing the rubber sealing ring 22 to be tightly inserted into the hatch cover body 21, thus achieving the closure and sealing of the hatch cover 2.
