Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, and specifically discloses a high-efficiency sealing structure for a ship hatch cover. Background Technology

[0002] Ships are a general term for all kinds of vessels. A ship is a means of transportation capable of navigating or anchoring on water for transport or operations. Depending on different usage requirements, ships have different technical specifications, equipment, and structural forms. A ship is a man-made means of transportation that primarily operates in geographical waters. Civilian ships are generally called boats, military ships are called warships, and small boats are called boats or dinghies; collectively, they are called ships or vessels. Hatch covers are an important component of a ship. Hatch covers are the closing devices for deck openings, serving to seal hatches, protect cargo, and partially support the platform.

[0003] Chinese Patent No. CN219115655U discloses a cargo hold hatch cover limiting and sealing structure and a ship. The cargo hold hatch cover limiting and sealing structure includes a hatch cover body, an upper limiting block fixedly disposed on one side of the hatch cover body; a lower limiting block, which is fixedly disposed on the hatch top plate and has a limiting groove. When the hatch cover body is closed, the upper limiting block is inserted into the limiting groove; and a sealing assembly, which is disposed between the hatch cover body and the hatch top plate to achieve a seal between the hatch cover body and the hatch top plate. This utility model can effectively limit the hatch cover while having a simple structure, low cost, and can effectively ensure the sealing performance between the hatch cover and the hatch top plate.

[0004] The aforementioned document only achieves sealing through a single-point contact between the elastic seal and the abutment block, failing to form a multi-layered protection system. Its sealing principle relies on the deformation compensation of the elastic element, making it prone to seal failure during ship turbulence or sudden pressure changes. Furthermore, the material of the elastic seal does not explicitly mention a reinforcing structure, leading to plastic deformation under long-term alternating loads, resulting in insufficient seal compression and affecting the sealing effect. Therefore, a highly efficient sealing structure for ship hatch covers is needed to solve this problem. Utility Model Content

[0005] This invention proposes a high-efficiency sealing structure for ship hatch covers. By adopting a multi-layer sealing design that combines main sealing elements with auxiliary sealing elements, a three-dimensional sealing system of "main seal + side auxiliary" is formed, which significantly improves the sealing performance and effectively reduces the risk of seawater leakage. Furthermore, it gives the sealing components good wear resistance and structural strength, thereby improving the sealing effect.

[0006] This utility model is implemented as follows: a high-efficiency sealing structure for a ship hatch cover includes a hatch coaming and a hatch cover body that cooperates with the hatch coaming. The bottom edge of the hatch cover body is provided with a sealing mounting groove, and a sealing component is provided in the sealing mounting groove. The top of the hatch coaming is provided with a sealing groove that is adapted to the sealing component.

[0007] The sealing assembly includes a main seal and two auxiliary seals. The main seal is located in the middle of the sealing mounting groove, and the two auxiliary seals are symmetrically arranged on both sides of the main seal.

[0008] The sealing groove has a main sealing groove in the middle that matches the main sealing element, and auxiliary sealing grooves on both sides of the main sealing groove that match the auxiliary sealing element.

[0009] As a preferred embodiment of the efficient sealing structure for a ship hatch cover according to this utility model, the main sealing element is a hollow rubber strip with a metal reinforcing skeleton inside.

[0010] As a preferred embodiment of the efficient sealing structure for a ship hatch cover according to this utility model, the auxiliary sealing element is a solid polyurethane strip, and the side of the auxiliary sealing element facing the sealing groove has an arc-shaped protrusion structure that matches the auxiliary sealing groove.

[0011] As a preferred embodiment of the efficient sealing structure of the ship hatch cover of this utility model, the inner wall of the main sealing groove is provided with an elastic buffer layer, which is made of nitrile rubber material.

[0012] As a preferred embodiment of the efficient sealing structure of the ship hatch cover according to the present invention, the contact edge between the hatch cover body and the hatch coaming is provided with an anti-corrosion coating, which is made of epoxy resin material.

[0013] The beneficial effects of this utility model are:

[0014] 1. By aligning the main seal with the main sealing groove and inserting the auxiliary seal into the auxiliary sealing groove, after closing the hatch cover body, the sealing assembly forms a multi-layer seal with the sealing groove under the weight of the hatch cover body. Furthermore, by adopting a multi-layer sealing design that combines the main seal and the auxiliary seal, the main seal undertakes the main sealing function, while the auxiliary seal plays a supporting sealing and buffering role, forming a three-dimensional sealing system of "main seal + side auxiliary", which significantly improves the sealing performance and effectively reduces the risk of seawater leakage.

[0015] 2. The auxiliary seal, made of solid polyurethane strip, has good wear resistance and elasticity. The arc-shaped protrusion of the auxiliary seal can better fit with the sealing groove, improving the sealing effect. The metal reinforced skeleton and hollow rubber strip work together to enhance the structural strength and pressure resistance of the main seal. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-5 A high-efficiency sealing structure for a ship hatch cover includes a hatch coaming 1 and a hatch cover body 2 that cooperates with the hatch coaming 1. The bottom edge of the hatch cover body 2 is provided with a sealing mounting groove 4, and a sealing component is provided in the sealing mounting groove 4. The top of the hatch coaming 1 is provided with a sealing groove 3 that is adapted to the sealing component.

[0025] The sealing assembly includes a main seal 401 and two auxiliary seals 402. The main seal 401 is located in the middle of the sealing mounting groove 4, and the two auxiliary seals 402 are symmetrically arranged on both sides of the main seal 401.

[0026] The sealing groove 3 has a main sealing groove 301 in the middle that matches the main sealing element 401, and auxiliary sealing grooves 302 that match the auxiliary sealing element 402 on both sides of the main sealing groove 301.

[0027] In this embodiment: during the assembly of the hatch coaming 1 and the hatch cover body 2, the main sealing element 401 is aligned with the main sealing groove 301 and the auxiliary sealing element 402 is inserted into the auxiliary sealing groove 302. After the hatch cover body 2 is closed, the sealing components form a multi-layer seal with the sealing groove 3 under the weight of the hatch cover body 2. Thus, by adopting a multi-layer sealing design that combines the main sealing element 401 and the auxiliary sealing element 402, the main sealing element 401 undertakes the main sealing function, and the auxiliary sealing element 402 plays the role of auxiliary sealing and buffering, forming a three-dimensional sealing system of "main seal + side auxiliary", which significantly improves the sealing performance and effectively reduces the risk of seawater leakage.

[0028] As a technical optimization of this utility model, the main sealing element 401 is a hollow rubber strip 4012, which has a metal reinforcing skeleton 4011 inside.

[0029] In this embodiment, the structural strength and compressive strength of the main seal 401 can be enhanced by the combination of the metal reinforcing skeleton 4011 and the hollow rubber strip 4012.

[0030] As a technical optimization of this utility model, the auxiliary sealing element 402 is a solid polyurethane strip, and the side of the auxiliary sealing element 402 facing the sealing groove 3 is an arc-shaped protrusion structure that matches the auxiliary sealing groove 302.

[0031] In this embodiment, the auxiliary seal 402 is a solid polyurethane strip, which has good wear resistance and elasticity. By making the side of the auxiliary seal 402 facing the sealing groove 3 into an arc-shaped protrusion, it can fit better with the sealing groove 3 and improve the sealing effect.

[0032] As a technical optimization of this utility model, the inner wall of the main sealing groove 301 is provided with an elastic buffer layer 303, which is made of nitrile rubber material.

[0033] In this embodiment, the elastic buffer layer 303 made of nitrile rubber can buffer the main seal 401 when it comes into contact with the main sealing groove 301, thereby reducing wear.

[0034] As a technical optimization of this utility model, the contact edge between the hatch cover body 2 and the hatch coaming 1 is provided with an anti-corrosion coating, which is made of epoxy resin material.

[0035] In this embodiment, the anti-corrosion coating can effectively prevent seawater from corroding the contact edges, thus extending the service life of the structure.

[0036] The working principle and usage process of this utility model are as follows: During the assembly of the hatch coaming 1 and the hatch cover body 2, the main sealing component 401 is aligned with the main sealing groove 301 and the auxiliary sealing component 402 is inserted into the auxiliary sealing groove 302. After the hatch cover body 2 is closed, the sealing components form a multi-layer seal with the sealing groove 3 under the weight of the hatch cover body 2. By adopting a multi-layer sealing design that combines the main sealing component 401 and the auxiliary sealing component 402, the main sealing component 401 undertakes the main sealing function, and the auxiliary sealing component 402 plays the role of auxiliary sealing and buffering, forming a three-dimensional sealing system of "main seal + side auxiliary", which significantly improves the sealing performance and effectively reduces the risk of seawater leakage.

[0037] The auxiliary seal 402 is a solid polyurethane strip, which has good wear resistance and elasticity. By setting the side of the auxiliary seal 402 facing the sealing groove 3 as an arc protrusion, it can fit better with the sealing groove 3 and improve the sealing effect. The metal reinforcing skeleton 4011 and the hollow rubber strip 4012 together can enhance the structural strength and pressure resistance of the main seal 401.
