A flush deck anti-skid hatch cover device for a ship

Abstract

The present application relates to the field of hull deck machinery, and particularly relates to a hull deck embedded anti-skid hatch cover device. The hull deck embedded anti-skid hatch cover device of the present application has a grid plate on the hatch cover, and splashed seawater and rainwater directly flow into the sink structure of the hatch cover and then flow out through the water drainage channel structure. The grid plate has a small solid area and a high porosity, and has excellent anti-skid effect. In addition, the grid plate has less residual water on the surface, and has excellent anti-skid effect. The technical problem of the present application is that the anti-skid embossed structure on the embedded hatch cover of the hull deck is prone to form local water accumulation, and even form frost layer, which brings serious risk of falling for the staff. In addition, the residual salt after evaporation of the water accumulation will cause destructive corrosion to the metal base of the hatch cover.

Description

Technical Field

[0001] This invention relates to the field of ship deck machinery, and more particularly to a ship deck embedded anti-slip hatch cover device. Background Technology

[0002] In ship deck structures, embedded hatch covers are widely used because they are flush with the deck surface, facilitating cargo loading and unloading and personnel passage. These hatch covers typically have an anti-slip textured surface to provide necessary grip. While these textures improve friction to some extent in dry or wet conditions, their uneven surface also provides space for moisture accumulation. During navigation, seawater splashed onto the deck, as well as water from rain, snow, or daily washing, can easily seep into and remain in the grooves, gaps, and surrounding submerged structures of the texture. This water is difficult to completely drain by gravity, and the slow evaporation rate can lead to localized water accumulation over time, even in cold, humid sea conditions. In oceanic climates, residual moisture easily condenses into frost or even large areas of ice on textured surfaces and inside grooves. This ice fills the original anti-slip texture, drastically reducing the coefficient of friction and making the hatch cover surface even more slippery than a smooth surface. This poses a serious risk of falls for workers who need to work or patrol on the deck. In addition, after the water evaporates in the sun, it leaves behind high-concentration salt crystals. These salts adhere to the texture and grooves, continuously corroding the metal substrate of the hatch cover, causing pitting corrosion, crevice corrosion, and coating peeling, thus shortening the service life of the equipment. Currently, the removal of water and frost mainly relies on temporary measures such as manual shoveling, spreading salt, or laying anti-slip mats, which are not only labor-intensive but also inefficient. Summary of the Invention

[0003] To overcome the drawbacks of embedded anti-slip hatch covers on ship decks, such as the tendency for localized water accumulation and even frost formation, which poses a serious risk of falls for workers, and the residual salt after the water evaporates causing destructive corrosion to the metal substrate of the hatch cover, this invention provides an embedded anti-slip hatch cover device for ship decks.

[0004] The technical solution of this invention: A ship deck embedded anti-slip hatch cover device, comprising an embedded frame, a hatch cover, a load-bearing wheel, a hydraulic push rod, a mesh grating plate, a water collection box, and a drain pipe; the embedded frame is provided with two hatch covers, left and right; the left hatch cover is rotatably connected to the embedded frame via a hinge structure; the two hatch covers are also rotatably connected to each other via a hinge structure; the right hatch cover is rotatably connected to a load-bearing wheel that moves along the surface of the embedded frame; a hydraulic push rod that drives the left hatch cover to flip up and down is rotatably connected to the embedded frame via a rotating shaft; a sinkhole structure is provided on the upper side of the hatch cover; a mesh grating plate covering the corresponding sinkhole structure is fixed on the upper side of the hatch cover; a water collection box is fixed to each opposite side of the hatch cover; the sinkhole structure of the hatch cover has several drainage channel structures connected to the corresponding water collection box; each water collection box is connected to a drain pipe, and the drain pipe is connected to a drainage system.

[0005] Preferably, the hatch cover has several reinforcing strips fixed inside the trough structure, and all the reinforcing strips together divide the inside of the trough structure into several independent drainage channel structures.

[0006] Preferably, each of the reinforcing strips has several through-channel structures at its bottom that connect two adjacent independent drainage channels.

[0007] Preferably, a sealing gasket is fixedly attached to the bottom of the hatch and closely fitted into the frame.

[0008] Based on the above scheme, preferably, a spray pipe is connected to each of the opposing sides of the upper surfaces of the two hatches; the spray pipe is provided with several nozzle structures; the mesh grille is provided with several spray inlet channel structures on each of the opposing sides; the nozzle structures of the spray pipe face the corresponding spray inlet channel structures on the same side.

[0009] Preferably, the spray pipe is rotatably connected to the corresponding hatch cover; the hatch cover is equipped with an electric rotary machine that drives the spray pipe on the same side to rotate.

[0010] Preferably, an electric heater is installed on the hatch cover to heat the water flow inside the spray pipe on the same side.

[0011] Compared with the prior art, the present invention has the following advantages: The present invention provides an embedded anti-slip hatch cover device for a ship's deck. The hatch cover is equipped with a mesh grating plate. Splashed seawater and rainwater will directly flow into the trough structure of the hatch cover and then be discharged outwards through the drainage channel structure. The mesh grating plate has a small solid area and high porosity, resulting in excellent anti-slip effect. Furthermore, the mesh grating plate has minimal residual moisture, further enhancing its anti-slip performance. A hydraulic push rod can simultaneously pull the right hatch cover to the left, facilitating simultaneous rinsing of the mesh grating plate and the trough structure of the hatch cover. Simultaneously, the inclined structure of the hatch cover allows for convenient drainage of accumulated wastewater. This solves the technical problem that the anti-slip textured structure on the embedded hatch cover of the ship's deck easily leads to localized water accumulation, even frost formation, posing a serious risk of falls for workers. It also addresses the issue that residual salt after water evaporation can cause destructive corrosion to the metal substrate of the hatch cover. Furthermore, this invention extends the lifespan of the main structure of the hatch cover. Attached Figure Description

It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0014] Example 1: A ship deck embedded anti-slip hatch cover device according to this embodiment, such as... Figures 1-6 As shown, the system includes an embedded frame 1, hatch covers 2, load-bearing wheels 21, hydraulic push rods 3, a mesh grating 4, a water collection box 5, a drain pipe 51, and a sealing gasket 6. The embedded frame 1 is embedded and installed on the ship's deck. The embedded frame 1 has two hatch covers 2, initially laid flat in a straight line and tightly covering the embedded frame 1. The left hatch cover 2 is rotatably connected to the embedded frame 1 via a hinge structure. The two hatch covers 2 are also rotatably connected to each other via a hinge structure. The right hatch cover 2 has two load-bearing wheels 21 rotatably connected to its right side. Both load-bearing wheels 21 are tightly attached to the embedded frame 1. Two hydraulic push rods 3 are rotatably connected inside the embedded frame 1 via a rotating shaft. The telescopic ends are rotatably connected to the left hatch cover 2 via a pivot shaft; each of the two hatch covers 2 has a sinkhole structure 201 on its upper side; each of the two hatch covers 2 has a detachable mesh plate 4 fixed on its upper side, and the mesh plate 4 covers the sinkhole structure 201 on the same side; each of the two hatch covers 2 has a water collection box 5 fixed to its opposite side; each of the two hatch covers 2 has several drainage channel structures 202 on its sinkhole structure 201, which are respectively connected to the corresponding water collection box 5; each of the two water collection boxes 5 has a drain pipe 51 connected to it, and the drain pipe 51 is connected to a drainage system; each of the two hatch covers 2 has a sealing gasket 6 fixed to its bottom; both sealing gaskets 6 are tightly fitted into the frame 1 to enhance the sealing effect between the hatch cover 2 and the frame 1.

[0015] like Figure 5 and Figure 6 As shown in this embodiment, an embedded anti-slip hatch cover device for a ship deck is provided. Each of the two hatch covers 2 has several reinforcing strips 22 fixedly connected to the sinkhole structure 201. The reinforcing strips 22 effectively strengthen the structural strength of the entire hatch cover 2. All the reinforcing strips 22 together divide the interior of the sinkhole structure 201 into several independent drainage channel structures. Each reinforcing strip 22 has several through-channel structures 2201 at its bottom. The through-channel structures 2201 connect two adjacent independent drainage channel structures.

[0016] This embodiment describes a ship deck embedded anti-slip hatch cover device. Two hatch covers 2 are initially laid tightly and flat on the embedded frame 1. During navigation, seawater splashed onto the deck and rainwater falling onto the deck during rainy weather will flow directly through the mesh grating plate 4 into the sinkhole structure 201 of the hatch cover 2. The water in the sinkhole structure 201 then flows through the drainage channel structure 202 into the water collection box 5 and is discharged through the drainage pipe 51 along the external drainage system. If an independent drainage channel structure in the sinkhole structure 201 is blocked by accumulated impurities, the water in that independent drainage channel structure will flow through the through channel structure 2201 to the adjacent independent drainage channel structure, allowing the water to pass smoothly through the drainage channel structure 202 and be discharged. The mesh grating plate 4 has a small solid area and a high porosity, providing excellent anti-slip effect. Moreover, there is little residual water on the surface of the mesh grating plate 4, making it less likely for workers to slip while walking on it. In sunny weather, the seawater remaining on the surface of the mesh grating plate 4 will also be quickly dried.

[0017] After the ship docks, when loading and unloading are required, the hydraulic push rod 3 pushes the left hatch cover 2 upwards. During this upward movement, the right hatch cover 2 is simultaneously pulled, causing the load-bearing rollers 21 to retract to the left along the embedded frame 1, completing the opening of both hatch covers 2. At this time, both hatch covers 2 are in an inclined state. After unloading, the two hatch covers 2 are maintained and washed. While the hatch covers 2 remain in their upward-tilted state, workers use water spray guns to spray water downwards towards the mesh grating plate 4 for washing. Simultaneously, some water flows through the mesh grating plate 4 and into the sinkhole structure 201 of the hatch cover 2. During the flushing process, the water flow continuously downward along the inclined settling trough structure 201 inside the hatch cover 2 can flush away the accumulated impurities in the independent drainage channel structure. The accumulated impurities are flushed into the water collection box 5 and then discharged through the drain pipe 51 along the external drainage system, thus simultaneously completing the flushing work inside the settling trough structure 201 of the hatch cover 2 and the grating plate 4. At the same time, the inclined state of the hatch cover 2 is used to conveniently complete the sewage discharge treatment. If the accumulated impurities in the independent drainage channel structure are severely blocked and it is difficult to flush them out, the grating plate 4 can be removed from the hatch cover 2 for manual cleaning.

[0018] Example 2, based on Example 1, such as Figures 1-6As shown in this embodiment, an embedded anti-slip hatch cover device for a ship's deck has a spray pipe 7 rotatably connected to the opposing sides of the upper surfaces of two hatch covers 2, and the spray pipe 7 is externally connected to a water flow conveying device; each of the two spray pipes 7 has a plurality of nozzle structures 701; each of the two mesh grilles 4 has a plurality of spray inlet channel structures 401 on the opposing sides; the nozzle structures 701 of the two spray pipes 7 are respectively oriented towards the corresponding spray inlet channel structures 401 on the same side; each of the two hatch covers 2 is equipped with an electric rotating machine 71; the rotating parts of the two electric rotating machines 71 are respectively fixed to the corresponding spray pipes 7; each of the two hatch covers 2 is equipped with an electric heater 72; the heating parts of the two electric heaters 72 are respectively connected to the corresponding spray pipes 7.

[0019] This embodiment of a ship deck embedded anti-slip hatch cover device continuously supplies water to the spray pipe 7 via an external water supply device. The spray pipe 7 sprays water towards the spray inlet channel structure 401 of the mesh grating plate 4 through the nozzle structure 701. The water enters the sink trough structure 201 of the hatch cover 2, automatically replacing manual washing and reducing the workload of manual maintenance. In addition, in cold climates, the surface of the mesh grating plate 4 is prone to large-area frost due to the adhesion of moisture. The frost layer can easily cause slippage on the surface of the mesh grating plate 4. Therefore, when the surface of the mesh grating plate 4 is frosted, if workers need to stand on the mesh grating plate 4 to work, the water supply should be continuously sprayed by the external water supply device. Water is transported inside pipe 7, and the water flows out through the nozzle structure 701. At the same time, the electric rotating machine 71 drives the spray pipe 7 to slowly rotate back and forth at the forward viewing angle, so that the water sprayed from the nozzle structure 701 covers each area of ​​the surface of the grid plate 4 in sequence. Meanwhile, the electric heater 72 heats the water in the spray pipe 7 to a warm state. The heat carried by the water flow is used to defrost the surface of the grid plate 4. After the frost layer melts into water, it flows through the grid plate 4 and into the sinkhole structure 201 of the hatch cover 2. This quickly eliminates the frost layer on the surface of the grid plate 4, which may cause slippage and ensure the personal safety of the staff. It also eliminates the labor intensity of manual frost removal and the mechanical damage to the grid plate 4 caused by manual frost removal.

They should not be construed as limiting the scope of protection of the present invention.
