Description

Technical Field

[0001] The utility model belongs to the technical field of fairlead holes, in particular to a shielding cover for a fairlead hole. Background Art

[0002] For ship fairlead holes, they are generally round or waist-shaped castings installed on the bulwarks to play a guiding and protective role. However, since the fairlead holes are exposed to the outside and are in an open state when not in use, seawater may flow in and cannot be effectively sealed. Water accumulation may occur, which may affect ship equipment and the safe use of the equipment. Therefore, designing a shielding cover for the fairlead hole is a problem that needs to be solved by the staff in this field. Utility Model Content

Through the design of a flippable shielding plate, the cable guide hole can be completely covered and shielded, thereby playing an efficient protective sealing role. At the same time, the cable guide hole can be completely exposed after flipping, without affecting the normal use of the cable guide hole, thereby improving the safety of the cable guide hole.

[0004] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0005] The utility model is a shielding cover for a fairlead hole, comprising a fairlead hole casting, a shielding plate, a transmission mechanism and a limiting mechanism, wherein the fairlead hole casting is installed on the bulwark;

[0006] A shaft is provided at a corner of the bottom of one side of the fairlead casting, and one corner of the bottom edge of the shielding plate is rotatably connected to the fairlead casting through the shaft;

[0007] The transmission mechanism comprises a rope body, a reversing wheel and a wire take-up device;

[0008] One end of the rope body is connected to the front side of the shielding plate, the reversing wheel and the wire take-up device are both fixed on the bulwark, the reversing wheel is located above the outer side of the fairlead casting, and the other end of the rope body is connected to the wire take-up device after passing around the reversing wheel;

[0009] The limiting mechanism includes a support seat and a barrier sleeve, wherein the support seat is fixed on the bulwark, the barrier sleeve is fixed to the support seat through a connecting plate, the rope body between the reversing wheel and the wire take-up device passes through the barrier sleeve and slidably cooperates with the barrier sleeve, and a positioning sleeve is fixed on the rope body below the barrier sleeve;

[0010] When the wire take-up device releases the wire, the shielding plate covers the front side of the fairlead casting, and the top end of the positioning sleeve and the bottom end of the barrier sleeve are in contact with each other;

[0011] When the wire take-up device takes up the wire, the shielding plate leans against the support seat in an inclined manner, and an obtuse angle is formed between the bottom edge of the shielding plate and the upper surface of the fairlead casting.

[0012] Furthermore, the fairlead casting comprises two end plates, a hole sleeve is connected between the two end plates, and the end plates are provided with holes connected to the hole sleeve.

[0013] Furthermore, one side of each of the end plates is provided with a supporting ear edge, a reinforcement sleeve is fixed between the two supporting ear edges, and the shaft body is fixed in the reinforcement sleeve.

[0014] Furthermore, a connecting sleeve is fixed to the front side of the shielding plate, the connecting sleeve and the shaft body are respectively located at the diagonals of the shielding plate, the connecting sleeve is rotatably connected to the shielding plate, and the end of the rope body is fixed to the connecting sleeve through a connector.

[0015] Furthermore, a groove is provided on the reversing wheel, the reversing wheel is fixed to the bulwark through a wheel seat, an anti-slip rod is provided on the wheel seat, and the anti-slip rod is fitted with the outer surface of the reversing wheel.

[0016] Furthermore, the front side and the rear side of the connecting plate form right-angled sides with the supporting seat, and a plurality of reinforcing ribs are linearly arranged at the right-angled sides.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model can completely cover and shield the fairing hole through the design of the flippable shielding plate, which plays an efficient protective sealing role. At the same time, the fairing hole can be completely exposed after flipping, which does not affect the normal use of the fairing hole and improves the safety of the use of the fairing hole.

[0019] 2. The utility model facilitates the operation of the shielding plate by designing a new transmission mechanism. At the same time, the distance between the reversing wheel and the wire take-up device can be adjusted according to the installation position of the cable guide hole, so that the wire take-up device is in a position that is convenient for the staff to operate, and has a wide range of applications.

[0020] 3. The utility model designs a new type of limiting mechanism, and the limiting functions after the shielding plate is opened and covered are integrated into one body, which is convenient for installation and production. At the same time, it can be directly installed on the bulwark, with strong fastness and stability. After the shielding plate is opened and covered, the gravity of the shielding plate will not cause tension to the wire take-up device, thereby ensuring the service life and position stability of the wire take-up device.

[0021] 4. The limit mechanism and transmission mechanism of the utility model are relatively far away from the cable guide hole, and will not affect the normal use of the cable guide hole after being opened, and the normal use of the cable guide hole will not affect the limit mechanism and the transmission mechanism, ensuring the service life and position stability of the limit mechanism and the transmission mechanism.
