Due to its flexibility, the lift-off hatch cover is currently widely used in high-end multi-purpose ships. However, due to its high installation and positioning requirements and difficult precision control, most domestic shipyards are currently unable to overcome the technical difficulties. Traditional hatch covers are usually fixed and positioned by structural forms. The disadvantage is that after long-term navigation and loading of goods by the shipowner, the cargo hold is severely deformed, resulting in the hatch cover being unable to be used normally, and the precision requirements during the installation of the hatch cover are also very high, which is not conducive to on-site installation.

[0003] In the prior art, there is a technology with the name of "a ship hatch cover sealing structure" and a publication number of "CN109552562B". This technology includes hatch panel A, hatch panel B, hatch panel C, electric telescopic rods, a frame, a hatch panel groove is opened on the frame, a folding crank is installed at one end of the frame, the folding crank is connected to a base, a lock is installed at the other end of the frame, the hatch panels are connected by electric telescopic rods, hatch panel C is installed on the frame, hatch panel B is above hatch panel C, and hatch panel A is above hatch panel B. This device realizes the contraction and folding function through three hatch panels, and is connected by electric telescopic rods to realize the contraction of the hatch panels electrically, so that when the ship needs to open the hatch, it is not necessary to open it one by one manually, which is convenient and fast, and the hatch cover can also be directly lifted by the lock, which is a new hatch cover sealing structure.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is: aiming at the deficiencies of the prior art, to provide a ship hatch cover structure with a simple structure, which can make the hatch cover be accurately installed at the required position according to the design, and can slide within a set range during and after installation, effectively solving the problems of difficult installation precision control and difficult installation of the hatch cover, and reliably ensuring the sealing performance.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the utility model is as follows:

[0007] The utility model is a ship hatch cover structure. The hatch cover is arranged at the ship hatch position. A positioning groove is arranged at the lower part of the hatch cover. An opening is arranged on the hatch panel of the ship hatch. A first limit block is arranged on one side of the hatch panel close to the opening, and a second limit block is arranged on the other side of the hatch panel close to the opening. The distance between the first limit block and the second limit block is greater than the width of the hatch cover.

[0008] A connecting rod member is arranged on the side of the hatch cover. The connecting rod member includes a hook portion, and a hook ring is arranged at a position close to the opening of the hatch panel.

[0009] A gasket installation groove is arranged at the lower part of the hatch cover, and a gasket is installed in the gasket installation groove.

[0010] Guide members are arranged on the inner edge of the opening.

[0011] A first sealing plate is arranged at a position of the hatch panel close to the first limit block, and a second sealing plate is arranged at a position of the hatch panel close to the second limit block.

[0012] The positioning groove includes a first positioning groove and a second positioning groove.

[0013] The guide members include a first guide member and a second guide member.

[0014] The gasket installation groove includes a first gasket installation groove and a second gasket installation groove, and the gasket includes a first gasket and a second gasket.

[0015] When the hatch cover is arranged at the ship's hatch position, one side of the hatch cover is arranged to be able to fit the first limit block, and the other side of the hatch cover is arranged to have a gap portion with the second limit block.

[0016] Adopting the technical solution of the present utility model, the working principle and beneficial effects are as follows:

[0017] For the structure of the ship's hatch cover described in the present utility model, when setting the structure, the hatch cover needs to cooperate with the ship's hatch to achieve the sealing of the ship's hatch. A positioning groove is arranged at the lower part of the hatch cover, and an opening is arranged on the hatch panel of the ship's hatch. The positioning groove is used for clamping and cooperating with the upper part of the guide member on the inner edge of the opening, and the positioning groove limits the moving range of the hatch cover relative to the guide member. A first limit block is arranged on one side of the hatch panel close to the opening, and a second limit block is arranged on the other side of the hatch panel close to the opening. The distance between the first limit block and the second limit block is greater than the width of the hatch cover. When arranging the hatch cover, one side of the hatch cover fits on the first limit block, and there is a gap portion between the other side of the hatch cover and the second limit block, so that the hatch cover has a certain movement space relative to the second limit block. In this way, when installing the hatch cover, the hatch cover can move within a certain range, rather than being strictly clamped between the first limit block and the second limit block without a gap portion, effectively reducing the installation difficulty of the hatch cover. After the hatch cover is installed in place, it can reliably seal the opening, ensure the sealing performance, and meet the use requirements. At the same time, because the hatch cover is not in a fixed state at the ship's hatch position, but can slide within a certain range, it overcomes the problem that the ship's hatch coaming deforms due to various factors such as temperature, sea conditions, and cargo loading at the ship's hatch position, which affects the sealing of the hatch cover to the ship's hatch, and improves the reliability.

Detailed Description of the Preferred Embodiment

[0023] The following further details the specific embodiments of the present utility model, such as the shapes, structures of the various components involved, the mutual positions and connection relationships between the various parts, the functions of the various parts, and the working principles, etc., with reference to the drawings:

[0024] As shown in the attached Figure 1 - attached Figure 3As shown in the figure, the utility model relates to a ship hatch cover structure. The hatch cover 1 is arranged at the position of the ship hatch 2. A positioning groove 4 is arranged at the lower part of the hatch cover 1. An opening 6 is arranged on the hatch panel 5 of the ship hatch 2. A first limiting block 7 is arranged on one side of the hatch panel 5 close to the opening 6, and a second limiting block 8 is arranged on the other side of the hatch panel 5 close to the opening 6. The distance between the first limiting block 7 and the second limiting block 8 is greater than the width of the hatch cover 1. For the deficiencies in the prior art, the above structure proposes an improved technical solution. When setting the structure, the hatch cover needs to cooperate with the ship hatch to realize the sealing of the ship hatch. A positioning groove 4 is arranged at the lower part of the hatch cover 1, and an opening 6 is arranged on the hatch panel 5 of the ship hatch 2. The positioning groove 4 is used for clamping and cooperating with the upper part of the guiding member 9 on the inner edge of the opening 6, and the positioning groove 4 limits the moving range of the hatch cover relative to the guiding member 9. A first limiting block 7 is arranged on one side of the hatch panel 5 close to the opening 6, and a second limiting block 8 is arranged on the other side of the hatch panel 5 close to the opening 6. The distance between the first limiting block 7 and the second limiting block 8 is greater than the width of the hatch cover 1. When arranging the hatch cover 1, one side of the hatch cover 1 is attached to the first limiting block 7, and there is a gap between the other side of the hatch cover 1 and the second limiting block 8, so that the hatch cover 1 has a certain moving space relative to the second limiting block 8. In this way, when installing the hatch cover 1, the hatch cover 1 can move within a certain range, rather than being strictly clamped between the first limiting block 7 and the second limiting block 8 without a gap, effectively reducing the installation difficulty of the hatch cover 1. After the hatch cover 1 is installed in place, it can reliably seal the opening 6, ensure the sealing performance, and meet the use requirements. At the same time, because the hatch cover 1 is not in a fixed state at the position of the ship hatch 2, but can slide within a certain range, it overcomes the problem that the ship hatch coaming deforms at the position of the ship hatch 2 due to various factors such as temperature, sea conditions, and cargo loading, which affects the sealing of the hatch cover 1 to the ship hatch 2, and improves the reliability. The ship hatch cover structure described in the utility model has a simple structure, can enable the hatch cover to be accurately installed at the required position according to the design, and can slide within a set range during and after installation, effectively solving the problems of difficult control of installation accuracy and difficult installation of the hatch cover, and reliably ensuring the sealing performance.

[0025] A connecting rod member 10 is arranged on the side surface of the hatch cover 1. The connecting rod member 10 includes a hook part 11. A hook ring 12 is arranged at the position of the hatch panel 5 close to the opening 6. In the above structure, when the hatch cover is arranged at the position of the ship hatch, vertical connection is realized through a plurality of connecting rod members 10. That is, the hook part 11 of the connecting rod member 10 is hooked on the hook ring 12 of the hatch panel 5, and the connection is reliable.

[0026] A gasket mounting groove 13 is provided at the lower part of the hatch cover 1, and the gasket 14 is installed in the gasket mounting groove 13. In the above structure, with the gasket installed in the gasket mounting groove 13, after the hatch cover is properly arranged, the gasket can reliably play a sealing role. The hatch cover can be of a circular structure or a square structure. When the hatch cover 1 is of a circular structure, the gasket mounting groove 13 and the gasket 14 are arranged along a circumference. When the hatch cover 1 is of a square structure, the gasket mounting grooves 13 and the gaskets 14 are provided in all four directions, ensuring a reliable seal is formed between the hatch cover and the ship's hatch.

[0027] A guide member 9 is provided on the inner edge of the opening 8. In the above structure, after the hatch cover is properly arranged, the positioning groove 4 is used to be clamped and fitted with the upper part of the guide member 9 on the inner edge of the opening 6, and the positioning groove 4 limits the movement range of the hatch cover relative to the guide member 9, avoiding excessive sliding amplitude.

[0028] A first sealing plate 3 is provided at the position of the hatch panel 5 close to the first limit block 7, and a second sealing plate 15 is provided at the position of the hatch panel 5 close to the second limit block 8. In the above structure, after the hatch cover is properly arranged, the sealing plate is used to fit with the gasket, reliably achieving the seal between the two.

[0029] The positioning groove 4 includes a first positioning groove 41 and a second positioning groove 42. In the above structure, the first positioning groove 41 and the second positioning groove 42 are structures shown in a partial cross-section. The positioning groove is actually an integral structure arranged along a circumference, which can be square or circular. The guide member 9 includes a first guide member 91 and a second guide member 92. In the above structure, the first guide member 91 and the second guide member 92 are structures shown in a partial cross-section. The guide member is actually a structure arranged along a circumference.

[0030] The gasket mounting groove 13 includes a first gasket mounting groove 131 and a second gasket mounting groove 132, and the gasket 14 includes a first gasket 141 and a second gasket 142. In the above structure, the first gasket 141 and the second gasket 142 are structures shown in a partial cross-section. The gasket is actually a structure arranged along a circumference, so as to reliably achieve the seal of the opening.

[0031] When the hatch cover 1 is arranged at the position of the ship's hatch 2, one side of the hatch cover 1 is set to a structure that can fit the first limit block 7, and the other side of the hatch cover 1 is set to a structure with a gap between the second limit block 8. The above structure allows the hatch cover 1 to move within a certain range when installing the hatch cover 1, instead of having to be strictly clamped between the first limit block 7 and the second limit block 8 without a gap, which effectively reduces the difficulty of installing the hatch cover 1. After the hatch cover 1 is installed in place, the opening 6 can be reliably closed to ensure sealing and meet the use requirements. Because the hatch cover 1 is not in a fixed state at the position of the ship's hatch 2, but can be in a sliding state within a certain range, the problem of deformation of the position of the ship's hatch 2 due to various factors such as temperature, sea conditions, and cargo loading is overcome, thereby affecting the sealing of the hatch cover 1 to the ship's hatch 2.

[0032] The ship hatch cover structure described in the utility model needs to cooperate with the ship hatch to seal the ship hatch when the structure is set. A positioning groove 4 is set at the lower part of the hatch cover 1, and an opening 6 is set at the hatch panel 5 of the ship hatch 2. The positioning groove 4 is used to fit with the upper part of the guide member 9 inside the opening 6. The positioning groove 4 limits the movement range of the hatch cover relative to the guide member 9. A first limit block 7 is set on the side of the hatch panel 5 close to the opening 6, and a second limit block 8 is set on the other side of the hatch panel 5 close to the opening 6. The distance between the first limit block 7 and the second limit block 8 is greater than the width of the hatch cover 1. When the hatch cover 1 is arranged, one side of the hatch cover 1 is attached to the first limit block 7, and there is a gap between the other side of the hatch cover 1 and the second limit block 8, so that the hatch cover 1 has a certain movement space relative to the second limit block 8. In this way, when installing the hatch cover 1, the hatch cover 1 can be moved within a certain range, instead of being strictly clamped between the first limit block 7 and the second limit block 8 without a gap, which effectively reduces the difficulty of installing the hatch cover 1. After the hatch cover 1 is installed in place, the opening 6 can be reliably closed to ensure the sealing performance and meet the use requirements. At the same time, because the hatch cover 1 is not fixed at the position of the ship's hatch 2, but can slide within a certain range, the problem of deformation of the position of the ship's hatch 2 due to various factors such as temperature, sea conditions, and cargo loading is overcome, thereby affecting the sealing of the hatch cover 1 to the ship's hatch 2, thereby improving performance reliability.

[0033] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
