Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ships, in particular to a hatch corner protector for bulk carriers and ore carriers. BACKGROUND

[0002] At present, most of the bulk carriers and ore carriers in operation only have protective devices such as half-round steel on the hatch end beam in the cargo hold and the upper part of the hatch coaming, which do not protect the key node of the hatch corner. The Common Structural Rules for Oil and Bulk Chemical Tankers, which came into effect in 2021, stipulates that "specific measures should be taken to prevent the cargo hold corner from being directly contacted by the vertical steel cable of the grab bucket during normal operation, which may cause mechanical damage". The existing protective devices are round steel or half-round steel, which are close to the free edge of the hatch corner to protect it, and the unloading plate is added to the local part of the hatch coaming to solve the problem of cargo accumulation in the hatch corner. This split structure does not wrap the key node of the hatch corner and the paint surface in all directions, and the grab bucket and steel cable still have the risk of damaging the hatch corner during the loading and unloading of the ship. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a hatch corner protector for protecting the corner plate and the hatch coaming at the hatch corner. The specific structure includes: an unloading plate arranged above the corner plate at the hatch corner and inclined towards the bottom deck of the cargo hold, the unloading plate includes a first arc-shaped edge curved towards the hatch corner in a concave arc shape, and the unloading plate further includes at least one edge abutting against the hatch coaming and fixedly connected with the hatch coaming; a protective cover arranged at the corner plate of the hatch corner and inclined towards the top deck of the cargo hold, the protective cover includes a second arc-shaped edge matched with the arc-shaped edge of the unloading plate, the first arc-shaped edge and the second arc-shaped edge are fixedly connected, and the protective cover further includes at least one edge abutting against the corner plate; and the unloading plate and the protective cover form a closed space with the hatch coaming.

[0004] With the above specific structure, the unloading plate protects the hatch corner from above, and the protective cover protects the hatch corner from below, thereby achieving all-round wrapping and protection of the key node of the hatch corner and the paint surface.

[0005] As a possible implementation manner, a reinforcing structure is arranged at the connection between the first arc-shaped edge and the second arc-shaped edge.

[0006] With the above possible implementation manner, the reinforcing structure can protect the connection between the unloading plate and the protective cover, thereby making the hatch corner protector more solid and increasing the service life.

[0007] As a possible implementation manner, the reinforcing structure is anti-abrasion round steel.

[0008] As a possible implementation manner, the two straight edges of the unloading plate are both in contact with the hatch coaming, and the two straight edges intersect at the hatch corner.

[0009] By using the above possible implementation manner, the unloading plate is completely in contact with the hatch coaming, so that a sealed structure is formed above the hatch corner, thereby enabling all-round protection of the key nodes of the hatch corner and the paint surface.

[0010] As a possible implementation manner, the edge of the protective cover in contact with the corner plate is a third arc-shaped edge.

[0011] As a possible implementation manner, a sealing filler is arranged at the gap between the unloading plate and the protective cover and the hatch coaming.

[0012] By using the above possible implementation manner, the sealing property of the sealing filler does not require absolute sealing, but only needs to ensure that the goods cannot enter the interior of the unloading plate and the protective cover. The sealing filler can effectively protect the key nodes of the hatch corner in the space covered by the unloading plate and the protective cover and prevent the paint surface from being abraded and falling off.

[0013] As a possible implementation manner, the sealing filler is cement.

[0014] By using the above possible implementation manner, the cement material is stable in material properties, resistant to corrosion, and low in cost.

[0015] As a possible implementation manner, the unloading plate is fixedly connected to the hatch coaming through the two straight edges.

[0016] As a possible implementation manner, the third arc-shaped edge is in non-fixed contact with the corner plate.

[0017] By using the above possible implementation manner, the protective cover is not fixedly connected to the corner plate of the hatch, so that the original strength and stress of the corner plate are not affected. BRIEF DESCRIPTION OF DRAWINGS

[0021] Below, the specific implementation methods of the present application are described in detail with reference to the accompanying drawings.

[0022] Firstly, it is explained that the corner plate is a protruding plate at the corner of the hatch formed by the part of the deck extending into the hatch coaming 1.

[0023] The present application relates to a cabin hatch corner protection device for protecting the corner plate and hatch coaming 1 at the corner of the hatch, such as Figure 1 As shown, it consists of an unloading plate 10 and a protective cover 20.

[0024] Among them, such as Figure 1 As shown, a cargo plate 10 is positioned above the corner panel at the hatch corner and slopes toward the bottom deck of the hold. The cargo plate 10 includes a first curved edge 11 that curves inwardly toward the hatch corner and forms a concave arc. The cargo plate 10 also includes at least one edge that mates with and is fixedly connected to the hatch coaming 1. The cargo plate 10 facilitates smooth loading and unloading of bulk carrier cargo and prevents cargo from accumulating in blind spots. The edges of the cargo plate 10 that mate with the hatch coaming 1 are two straight edges, which mate with the hatch coaming 1 and intersect at the hatch corner.

[0025] In this embodiment, the specific size of the unloading plate 10 is obtained by vertically rotating the normal line of the edge shape of the corner plate by 30 degrees and then sweeping it toward both sides of the corner.

[0026] In this embodiment, the unloading plate 10 is fixedly connected to the hatch coaming 1 by two straight edges. The connection method is welding. In other embodiments, other connection methods can also be used, such as riveting, bolting, or snap connection.

[0027] Among them, such as Figure 1 As shown, the protective cover 20 is positioned at the hatch corner plate and angled toward the cabin's top deck. The protective cover 20 includes a second curved edge that mates with the curved edge of the unloading deck 10. The first curved edge 11 is fixedly connected to the second curved edge. The protective cover 20 also includes at least one edge that mates with the corner plate. The unloading deck 10, the protective cover 20, and the hatch coaming 1 form an enclosed space. The edge of the protective cover 20 that mates with the corner plate is a third curved edge 21.

[0028] Among them, such as Figure 1As shown, a reinforcement structure 30 is provided at the connection between the first arcuate side 11 and the second arcuate side. The reinforcement structure 30 can increase the structural strength of the first arcuate side 11 and the second arcuate side, preventing the cabin hatch corner protection device involved in the embodiment of the application from being squeezed and deformed by foreign objects such as cargo.

[0029] In this embodiment, the reinforcement structure 30 is wear-resistant round steel. In addition, in other embodiments, other reinforcement structures 30 such as wear-resistant semi-round steel can also be used.

[0030] In this embodiment, the first curved side 11 and the second curved side are connected by welding; the wear-resistant round steel is also connected to the first curved side 11 and the second curved side by welding. Welding is a mature process and simple to operate. After welding, polishing is sufficient, which saves labor. In other embodiments, other connection methods may also be used, such as riveting, bolting, or snap-fit ​​connections.

[0031] Among them, such as Figure 1 As shown, the third arcuate edge 21 is in non-fixed contact with the corner plate. The protective cover 20 is not fixedly connected to the hatch corner plate, so as not to affect the original strength and stress of the corner plate.

[0032] In this embodiment, a sealing filler 40 is used to fill the gap between the third arc-shaped edge 21 and the corner plate.

[0033] Among them, such as Figure 1 As shown, sealing fillers 40 are installed in the gaps between the unloading deck 10, the protective cover 20, and the hatch coaming 1. Sealing fillers 40 do not require absolute sealing; they only need to prevent cargo from entering the interior of the unloading deck 10 and the protective cover 20. Sealing fillers 40 effectively protect the key hatch corners within the space enclosed by the unloading deck 10 and the protective cover 20, and prevent the paint from wearing away.

[0034] In this embodiment, the sealing filler 40 is cement. Cement is a material with stable phase properties, corrosion resistance, and low cost. In addition, in other embodiments, other types of sealing fillers 40 may also be used, such as cement, rubber plugs, etc.

[0035] In this embodiment, the unloading plate 10 and the protective cover 20 are made of steel plate, which can reduce the manufacturing cost of the cabin hatch corner protection device according to the embodiment of the application. The simple structure of the steel plate also makes the installation and replacement of the unloading plate 10 and the protective cover 20 faster and more convenient. In other embodiments, the unloading plate 10 and the protective cover can also be made of resin materials to meet different practical needs.

[0036] In the embodiment, the components such as the unloading plate 10, the protective cover 20, the reinforcing structure 30, etc. can be subjected to surface treatment process such as paint spraying after the connection assembly is completed, so as to improve the corrosion resistance.

[0037] In summary, the ship hatch corner protector of the embodiment of the present application adopts the full-enclosure technology, and completely solves the problem of hatch corner protection. The ship hatch corner protector of the embodiment of the present application is made of steel plate welding, and is not fixedly connected with the corner plate, so as not to affect the original ship structure strength. The ship hatch corner protector of the embodiment of the present application has simple structure, low cost, and is convenient and fast in maintenance, repair and replacement.
