As shown in fig. 2 to 5, a fairlead sealing device 200 according to a preferred embodiment of the present invention includes an enclosure 201 and a cover 202. The shroud 201 is used for connecting to the base 101 of the fairlead 100. In the use state, the enclosing plate 201 is connected to the inner side of the base body 101 of the cable guide hole 100. A side of the enclosure 201 opposite to the cover plate 202 is defined as a first surface 201 a; the first surface 201a is provided with a positioning rib 203. The positioning ribs 203 may be flat iron welded to the first surface 201 a. The cover plate 202 is rotatably connected with the enclosing plate 201 and can cover or open the through hole 102 of the cable guide hole 100. The cover plate 202 has a second surface 202 a; the second surface 202a is provided with a sealing position 204 corresponding to the positioning convex rib 203, and the positioning convex rib 203 is connected in the sealing position 204 in a pluggable manner; a first sealing plate 205 perpendicular to the second surface 202a is arranged on one side of the sealing position 204 close to the central axis of the through hole 102 of the cable guide hole 100; the sealing position 204 is further provided with a second sealing plate 206 arranged opposite to the first sealing plate 205; the height of the second seal plate 206 is lower than the height of the first seal plate 205.

Based on the above technical solution, the cover plate 202 is hinged on the base body 101 of the cable guide hole 100 through the enclosing plate 201. Cover plate 202 opens through hole 102 of fairlead 100 as the tether passes through hole 102. In the non-use state, the cover plate 202 covers the through hole 102, and the second surface 202a abuts against the surface of the base 101. In order to ensure the water tightness, the enclosing plate 201 is provided with a positioning convex rib 203, the cover plate 202 is provided with a sealing position 204 matched with the positioning convex rib 203 in a positioning way, and when the cover plate 202 covers the through hole 102, the positioning convex rib 203 is inserted into the sealing position 204, so that the cover plate 202 is sealed and covered on the cable guide hole 100. In order to improve the watertight effect, the cover plate 202 is further provided with a first sealing plate 205 and a second sealing plate 206.

The first sealing plate 205 and the second sealing plate 206 are both disposed perpendicular to the cover plate 202, and the first sealing plate 205 and the second sealing plate 206 are disposed in parallel and opposite. When the fairlead hole sealing device 200 meets water, seawater firstly passes through the second sealing plate 206, the positioning convex rib 203 and the sealing position 204, and then passes through the first sealing plate 205, which is equivalent to a triple waterproof structure, so that the water tightness of the region can be kept, the seawater invasion caused by the upward wave in the running process of the ship is prevented, and the navigation safety of the ship is ensured. Further, since the first sealing plate 205 is closer to the through hole 102 than the second sealing plate 206, the first sealing plate 205 is higher than the second sealing plate 206, and thus, it is possible to prevent most of seawater from entering the through hole 102, to further improve the sealing performance of the fairlead 100, and to solve the problem of sealing the fairlead 100 used in a watertight area.

In order to ensure that the second sealing plate 206 acts as a first waterproof layer, the height of the second sealing plate 206 is higher than the height of the positioning pad 207. A portion of the seawater is blocked when passing through the second sealing plate 206.

The positioning ribs 203 are disposed around the through-hole 102. Correspondingly, the cross section of the concave position is also annular, and seawater can be prevented from entering from the vertical and horizontal directions.

Additionally, the fairlead sealing apparatus 200 also includes a swivel 208. The first surface 201a has two ends disposed oppositely. The rotating member 208 is disposed at one end of the first surface 201 a; the enclosing plate 201 is rotatably connected with the cover plate 202 through the rotating piece 208, so that the connecting structure of the cover plate 202 and the enclosing plate 201 is similar to a door and a doorframe, and the cover plate 202 is opened and closed to cover or open the through hole 102. The rotating member 208 comprises a pin connected with the cover plate 202 and two lugs oppositely arranged on the lug plate; each ear plate is connected to the first surface 201 a; the pin shaft penetrates through the two lug plates and is rotationally connected with each lug plate.
