The tightening action of the fastening device 13 causes the sealing ring 15 to be deformed and form a sealed state with the fairlead hole 21. In this embodiment, four fastening devices 13 are preferably provided on the weatherproof and weathertight cover body 11, and the four fastening devices 13 are spaced apart in the circumference of the weatherproof and weathertight cover body 11, and the weatherproof and weathertight cover is fastened in stages, so that the sealing devices of each part of the weatherproof and weathertight cover structure in the circumferential direction can achieve sealing of the fairlead hole 21.

[0039] At the same time, in this embodiment, the weatherproof cover body 11 is configured to be hinged to the fairlead hole 21, making it easy for the staff to open and close the weatherproof cover when in use. Preferably, two hinge devices 12 are provided for connection, making the connection between the weatherproof cover body 11 and the fairlead hole 21 more convenient and tight, and the connection point is also relatively strong and not prone to damage. Since the fairlead hole 21 in this embodiment has a waist-shaped cross-section, the hinge device 12 is preferably installed on a longer side of the fairlead hole 21. Since the fairlead hole 21 also has some structures such as reinforcing ribs 17, the hinge device 12 needs to be arranged to avoid the corresponding reinforcing ribs 17 and the position is set according to actual conditions.

[0040] Optionally, the fastening device 13 includes a butterfly nut 132, the side wall of the fairlead hole 21 is provided with a mounting platform, the bolt 131 passes through the weatherproof and waterproof cover body 11 and is fixed on the mounting platform, and the butterfly nut 132 is arranged above the weatherproof and waterproof cover body 11 and is threadedly engaged with the bolt 131.
