Description

Technical Field

[0001] This invention belongs to the field of ship design technology, and specifically relates to a wave-blocking protection device for life rafts. Background Technology

[0002] Life rafts are essential escape equipment for crew members in the event of shipwreck and must be readily available at all times. Therefore, life rafts must be stored in the open and positioned as close to the ship's side as possible. For six-person life rafts, due to their distance from the ship's living quarters, their storage location typically lacks any protective shelter. In rough seas, the fiberglass protective hull is easily damaged, leading to the raft's loss or destruction; in even rougher seas, the entire raft and its protective hull may be swept overboard and lost.

[0003] The safety of crew members is difficult to guarantee, so appropriate equipment is necessary to effectively block wind and waves and ensure the safe storage of life rafts.

[0004] Therefore, how to provide a wave-blocking protection device for life rafts that can block wind and waves, has sufficient strength, and does not hinder the normal use of life rafts, ultimately ensuring the safe storage of life rafts, has become an urgent technical problem to be solved.

Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0033] like Figure 1 As shown, Figure 1 This is a schematic diagram illustrating the structure of a wave-blocking protection device for a life raft according to an embodiment of the present invention.

[0034] Figure 1 The present invention provides a wave-blocking protection device for a life raft, comprising: a set of water-blocking plates 1, a set of folded elbow plates (including folded elbow plates 5, folded elbow plates 6, folded elbow plates 7 and a set of reinforcing rib structures 2).

[0035] The water deflector 1 is an inclined surface structure used to guide waves to flow slowly upward. The inclined surface structure is designed to be inclined backward at a first predetermined angle relative to the vertical surface. The water deflector 1 is provided with side wing baffles extending towards the life raft at a second predetermined angle in the length direction. A predetermined number of structural holes for mitigating wave impact are evenly distributed on the water deflector 1. The side wing baffles have a trapezoidal structure that is smaller at the top and larger at the bottom.

[0036] The dimensions of the water deflector 1 are determined based on the dimensions of the fiberglass protective shell of the life raft.

[0037] In this embodiment of the invention, the thickness of the baffle plate 1 is 8mm, the structural hole is a φ120mm opening, the first predetermined angle is 75°, and the second predetermined angle is 135°.

[0038] It is understood that in other embodiments of the present invention, the first predetermined angle and the second predetermined angle may also be other angles depending on the specific circumstances, and the specific angle range is not specifically limited here.

[0039] The reinforcing rib structure is horizontally arranged on the side of the baffle plate near the life raft and passes through the vertically arranged elbow plate;

[0040] The reinforcing rib 2 and the folded elbow plate are welded together to form the water baffle 1.

[0041] In this embodiment of the invention, the reinforcing rib 2 is a spherical flat steel structure, and the number of ribs is 3; the number of the folded elbow plates is 3.

[0042] It is understood that in other embodiments of the present invention, the number of reinforcing ribs and folded elbow plates can be increased or decreased according to specific strength requirements, and the specific number is not specifically limited here.

[0043] In this embodiment of the invention, the device includes: a pad plate 8, a set of patch plates 9, a sealing plate 4, and a set of handrail structures 3.

[0044] A pad 8 is provided at the lower end of the baffle plate 1, and a set of drainage holes are provided on the pad 8 for draining water accumulated at the bottom of the baffle plate 1.

[0045] A reinforcing plate 9 is used to enhance the strength weakened by the reinforcing rib 2 penetrating the elbow plate. A sealing plate 4 connects to the upper end of the baffle plate 1.

[0046] The handrail structure 3 is a circular tube structure, which is fixedly connected to the top of the baffle plate. The two ends of the circular tube structure are respectively provided with circular plate seals.

[0047] In one embodiment of the present invention, the water baffle 1, the folded elbow plate (including folded elbow plate 5, folded elbow plate 6, and folded elbow plate 7), the reinforcing rib structure 2, the pad plate 8, the patch plate 9, and the sealing plate 4 are designed with Q235-B material, and the handrail structure 3 is made of seamless steel pipe.

[0048] like Figures 2 to 8 As shown, Figure 2 View A shows a wave-protection device structure for a life raft according to an embodiment of the present invention. Figure 3 A GG view showing the structure of a wave-blocking protection device for a life raft according to an embodiment of the present invention. Figure 4 FF view showing the structure of a wave-blocking protection device for a life raft according to an embodiment of the present invention. Figure 5 A BB view showing the structure of a wave-protecting device for a life raft according to an embodiment of the present invention. Figure 6 A CC view showing the structure of a wave-protecting device for a life raft according to an embodiment of the present invention. Figure 7 A DD view showing the structure of a wave-protecting device for a life raft according to an embodiment of the present invention. Figure 8 View II shows the structure of a wave-blocking protection device for a life raft according to an embodiment of the present invention.

[0049] In the diagram, based on the common dimensions of the fiberglass protective shell of a 6-person life raft, the dimensions of the wave-blocking protection device are determined, namely, a length of 1400mm and a height of 1000mm.

[0050] Evenly increase the number of φ120mm openings on the wave-blocking protection device plate to reduce the wave impact force on the wave-blocking protection device; at the same time, the plate thickness is determined to be 8mm based on experience. In addition, considering that the impact force of the waves at the bow is extremely large, the wave-blocking protection device is set to tilt backward at 75 degrees, which can guide the waves to flow slowly upward, reduce the impact force, and also prevent the 8mm wave-blocking protection device plate from being deformed by the waves.

[0051] A φ42mm round tube is installed as reinforcement at the top of the wave-damping protection device, serving as a handrail and enhancing aesthetics. Additionally, round plates are installed at both ends of the tube to prevent internal rusting. To prevent the life raft from being impacted by the sides of waves, a side wing baffle extends rearward at a 135-degree angle along a length of 1400mm, increasing the protection area for the raft. For added aesthetics, this baffle is designed as a trapezoid, wider at the bottom and narrower at the top.

[0052] To increase structural strength, three HP100x6 bulb flats are installed horizontally, and three L8 / 50 folded elbow plates are installed vertically. Since the bulb flats need to penetrate the elbow plates, an 8mm reinforcement plate is added to supplement strength. To facilitate the reinforcement of the deck substructure of the wave protection device, a 12x100mm pad is installed at the bottom of the device. Additionally, a 30x60 R15 drainage hole is installed at the bottom to drain accumulated water.

[0053] In this embodiment of the invention, a wave-blocking protection device for a life raft includes: a set of water-blocking plates, a set of folded-edge elbow plates, and a set of reinforcing ribs. The water-blocking plates are inclined surface structures designed to guide waves to flow slowly upwards. The inclined surface structures are designed to be tilted backwards at a first predetermined angle relative to the vertical surface, and the water-blocking plates have side wing baffles extending towards the life raft at a second predetermined angle along their length. A predetermined number of structural holes for mitigating wave impact are evenly distributed on the water-blocking plates. The size of the water-blocking plates is determined according to the size of the fiberglass protective shell of the life raft. The reinforcing ribs are horizontally arranged on the side of the water-blocking plates closest to the life raft and penetrate the vertically arranged folded-edge elbow plates. The reinforcing ribs and the folded-edge elbow plates are welded together to the water-blocking plates.

[0054] The technical solution of this invention can block wind and waves, has sufficient strength, and does not hinder the normal use of the life raft. It effectively blocks the impact of sea waves, protects the life raft to the greatest extent, and can be widely used for life rafts in places without any shelter or protection, ultimately achieving the goal of ensuring the safe storage of life rafts.

[0055] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
