[0004] Although the above patent can play a role in wear resistance and protection, it does not have a wave-blocking structure. When the ship is sailing, due to the high winds and waves at sea, the ship's cable room is often flooded. The seawater entering the cable room will corrode the equipment in the cabin and cause safety hazards to some electrical equipment. If it is not removed in time, the water in the cable room will also remain in other rooms, causing great safety hazards. Therefore, we propose a ship cable guide hole wave-blocking device.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Through the structural design of the frame and the baffle, effective waterproofing of the fairlead is achieved. The frame not only increases the structural strength of the baffle, but also allows the baffle to be rotated and adjusted through the design of the first hinge and the second hinge, which is convenient for opening and closing. The sharp hook ensures the firm connection between the baffle and the ship, and the limit device provides an additional positioning function to prevent shaking in severe sea conditions.

The coordinated use of the hinge and the rotating shaft increases the dynamic adaptability of the baffle, prevents it from generating friction on the cable, extends the service life of the cable, and also reduces the burden on the ship's mooring system.

[0017] 3. The design of the first accommodating cavity and the second accommodating cavity between the frame and the baffle provides space for accommodating the sealing gasket and the ship cable guide groove.

DETAILED DESCRIPTION

[0025] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown, an embodiment of the utility model provides a ship fairlead hole wave blocking device.

[0027] It includes a baffle 2, the outer side of the baffle 2 is fixedly connected to a frame 1, the lower part of the frame 1 is provided with a first hinge 4 and a second hinge 5, the rear part of the first hinge 4 is provided with a first vertical extension section 41, the rear part of the second hinge 5 is provided with a second vertical extension section 51, the front sides of the first hinge 4 and the second hinge 5 are provided with a sharp hook portion 10, the sharp hook portion 10 is fixedly connected to the baffle 2, and the upper part of the frame 1 is provided with two screw holes, and a limiting device 3 is installed in the screw holes.

[0028] The key innovation of the ship fairlead wave stop provided by the embodiment of the utility model lies in the unique design of the hinge and the sharp hook portion 10, and the ingenious application of the limit device 3, which aims to solve the problem of the single ship fairlead protection structure and poor adaptability in the prior art.

[0029] First, the arrangement of the first hinge 4 and the second hinge 5, especially the first vertical extension section 41 and the second vertical extension section 51 at the rear, the first hinge 4 and the second hinge 5 are damping hinges, which endow the baffle 2 with the ability to be installed in a hinged manner, so that it can be flexibly adjusted according to the size of the waves. This design is different from the traditional fixed fairlead wave stop, which can actively adapt to the changing sea conditions and be half-open or fully open, significantly reducing the possibility of waves entering the cabin, and improving the safety and economy of ship operations.

[0030] Secondly, the fixed connection between the sharp hook portion 10 and the baffle 2 ensures the stability of the entire structure in harsh environments. The design of the sharp hook portion 10 not only increases the reliability of the connection of the baffle 2, but also plays an anchoring role to a certain extent, and can keep the baffle 2 stable even in strong winds and waves, avoiding safety hazards caused by the loosening of the baffle 2. This design is not common in existing ship fairlead protection structures, so it has significant innovation.

[0031] Furthermore, the limit device 3 installed in the screw hole on the upper part of the frame 1 is another innovation. The limit device 3 can not only rotate the limit plate 33 to limit the baffle 2 or lower the baffle 2 by adjusting the position of the screw 31, but also serve as an emergency locking mechanism in extreme cases to prevent the baffle 2 from detaching from the hull due to excessive swinging, thereby ensuring the safety of the ship under extreme conditions. The addition of the limit device 3 makes up for the defect of the lack of effective limit means in the prior art and improves the safety redundancy of the entire system.

[0032] In summary, the utility model creatively solves the flexibility and stability problems of the ship's cable guide hole protection structure through the above key steps, which not only improves the safety of ship operations, but also optimizes the waterproof efficiency of the cable hole, and has significant economic benefits and social value. These innovative points have not been fully demonstrated in the prior art, reflecting the originality and practicality of the invention.

[0033] The first hinge 4 and the second hinge 5 are respectively provided with mounting holes at their lower parts, and the rotating shaft 14 is connected in the mounting holes.

[0034] The thickness of the frame 1 is greater than that of the baffle 2 , and a first accommodating cavity 7 is formed between the frame 1 and the baffle 2 .

[0035] A sealing gasket 9 is fixedly connected to the interior of the first accommodating cavity 7 . A waist-shaped notch 12 is provided in the middle of the sealing gasket 9 . The sealing gasket 9 is a rubber cushion layer.

[0036] A second accommodating cavity 13 is formed between the sealing gasket 9 and the frame 1 , and a ship fairlead groove 6 is provided inside the second accommodating cavity 13 .

[0037] A first wear-resistant pad 8 is bonded to the left and right sides of the first hinge 4, and a second wear-resistant pad 11 is bonded to the left and right sides of the second hinge 5. Both the first wear-resistant pad 8 and the second wear-resistant pad 11 are nylon cushion layers.

[0038] The limiting device 3 includes a screw rod 31 , which is connected to the frame 1 via a thread, one end of the screw rod 31 is fixedly connected to a ring sleeve, and the other end of the screw rod 31 is provided with a bolt head.

[0039] The screw rod 31 is connected to a limiting plate 33 , and a through hole for the screw rod 31 to pass through is formed on the limiting plate 33 . The screw rod 31 is connected to a butterfly nut 32 , and the butterfly nut 32 and the limiting plate 33 are arranged on the front side of the baffle 2 .

[0040] The first hinge 4 and the second hinge 5 are connected by the shaft 14: the rotational freedom of the baffle 2 is ensured, and it is allowed to be adaptively adjusted according to different wave strengths. The design of the shaft 14 enables the baffle 2 to rotate smoothly, reducing friction loss. Compared with the fixed baffle 2, this design greatly improves the durability and maintenance cycle of the equipment, and solves the technical problems of the traditional baffle 2 being easy to wear and inconvenient to adjust. The shaft 14 is covered with a damping sleeve.

[0041] The first accommodating cavity 7 between the frame 1 and the baffle 2: This design not only increases the overall rigidity of the structure, but also provides installation space for the subsequent sealing gasket 9, which is a significant improvement over the traditional plane connection. The existence of the first accommodating cavity 7 means that the connection between the baffle 2 and the frame 1 is tighter, reducing the chance of seawater penetration and improving the overall waterproof performance.

[0042] Sealing gasket 9 and its oval-shaped notch 12: The sealing gasket 9 is made of rubber material and is fixed inside the first accommodating chamber 7. The oval-shaped notch 12 in the middle serves as an exhaust hole to prevent excessive air pressure when closed. The sealing gasket 9 reduces the intrusion of water and salt, and effectively avoids cable corrosion and equipment aging. This is an important upgrade to the simple sealing method in the prior art, and significantly enhances the reliability of long-term use.

[0043] The ship's cable guide groove 6 in the second accommodating chamber 13: The establishment of the second accommodating chamber 13 provides an independent installation area for the cable guide groove, which not only simplifies the installation process, but also facilitates later maintenance. The design of the cable guide groove ensures that the cable is not easy to deviate from the predetermined path during use, reduces the unexpected friction between the cable and the hull or other components, thereby extending the cable life and improving the operation efficiency.

[0044] The first wear pad 8 and the second wear pad 11 are set up as follows: the wear pads made of nylon are bonded to both sides of the hinge, directly facing the possible friction source. This design reduces the wear of the hinge during rotation and improves the durability of the hinge. The introduction of the wear pad is an innovation specially considered for the frequent movement of the hinge. It effectively solves the technical problem of the hinge area being vulnerable to damage and reduces maintenance costs.

[0045] The combination of the screw rod 31, the limiting plate 33 and the butterfly nut 32 of the limiting device 3: The innovation of the limiting device 3 lies in its adjustability. Through the threaded connection between the screw rod 31 and the frame 1, and the cooperation between the butterfly nut 32 and the limiting plate 33, the limiting control of the baffle 2 is realized. This design allows the user to quickly adjust the position of the baffle 2 according to actual needs without tools, which greatly improves the convenience and safety of operation and is a flexible limiting solution lacking in the prior art.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
