Further, a defogger is detachably arranged on the cabin ventilation shutter 2, and the defogger is in the shape of a dense mesh.

[0037] The ventilation equipment components include ventilation relay components, ventilation fan components and ventilation wind and rain tight covers. The ventilation relay components are arranged on the deck 3, the ventilation fan components are arranged on the fan protection components, and the ventilation wind and rain tight covers are arranged on the ventilation fan components. The ventilation relay components include bellows 4, fillers and guide pipes. One end of the bellows 4 is arranged on the deck 3, and the bellows 4 is connected with the relay through hole on the deck 3. The relay through hole is connected with the internal cabin of the ship and is used for ventilation to the internal cabin of the ship. The guide pipe is embedded in the bellows 4 and is used to guide the air circulation in the two ends of the bellows 4. The filler is filled in the space between the guide pipe and the bellows 4.

[0038] The ventilation fan component includes an elastic pad 5 and a ventilation fan 6, and the elastic pad 5 is arranged on a support seat 7 on the inner wall of the fan protection room 1, and is used to support and install the ventilation fan 6. Furthermore, three elastic pads 5 are provided, and the three elastic pads 5 are evenly distributed around the circumference. The ventilation fan 6 is horizontally installed on the elastic pad 5 through a mounting plate 8 on the side wall at one end. Furthermore, the three mounting plates 8 correspond to the three elastic pads 5 one by one. The other end of the ventilation fan 6 is detachably connected to the other end of the bellows 4. It should be noted that the ventilation fan 6 is used to supply or extract air into the internal cabin of the ship.

[0039] The ventilation wind and rain tight cover comprises a tight cover seat 9 and a tight cover 10. The tight cover seat 9 is generally in a shape of a different diameter. The small end of the tight cover seat 9 is horizontally detachably installed on a port of the ventilation fan 6. The diameter of the tight cover 10 is not less than the diameter of the large end of the tight cover seat 9. One side of the tight cover 10 is connected to the tight cover seat 9 through a hinge seat 11, so that the tight cover 10 can rotate through the hinge seat 11 to open the tight cover seat 9 or close and seal the large end of the tight cover seat 9 as needed.

[0040] The automatic lid opening and closing member includes a lid opening and closing transmission member and a lid opening and closing power member, and both the lid opening and closing transmission member and the lid opening and closing power member are arranged on the fan protection room. The lid opening and closing transmission member includes a first lid opening and closing transmission member and a second lid opening and closing transmission member, and both the first lid opening and closing transmission member and the second lid opening and closing transmission member are arranged in the fan protection room 1.

[0041] The first sealing cover opening and closing transmission member includes a capstan 12, a transmission rope 13, a first steering wheel 14 and a second steering wheel 15. The capstan 12 is fixedly mounted on the inner wall of the fan protection room 1. One end of the transmission rope 13 is wound around the capstan 12. The other end of the transmission rope 13 is fixedly connected to the opening and closing transmission block 16 on the sealing cover 10 after being turned by the first steering wheel 14 and the second steering wheel 15 installed on the inner wall of the fan protection room 1. One side of the opening and closing transmission block 16 is hinged to the sealing cover 10. When the capstan 12 rotates forward, the transmission rope 13 pulls the sealing cover 10 to rotate around the hinged seat 11 to open the large end of the sealing cover seat 9, so that the ventilation fan 6 can ventilate the internal cabin of the ship. Further, the transmission rope 13 is a steel wire rope.

[0042] The second sealing cover opening and closing transmission member includes a transmission shaft 17, a transmission sleeve 18, a transmission slide rod 19 and a transmission slide tube 20. One end of the transmission shaft 17 is rotatably arranged on a first rotating seat 21 on the inner wall of the fan protection room 1, and the other end of the transmission shaft 17 is rotatably arranged on a second rotating seat 22 on the inner wall of the fan protection room 1, so that the transmission shaft 17 is circumferentially rotated and axially locked on the first rotating seat 21 and the second rotating seat 22. The transmission sleeve 18 is fitted on the transmission shaft 17, and the internal thread of the inner wall of the transmission sleeve 18 is matched with the external thread of the outer wall of the transmission shaft 17. When the transmission shaft 17 rotates forward, the transmission sleeve 18 is pushed upward by the external thread and the internal thread. One end of the transmission slide rod 19 is horizontally fixed on the transmission sleeve 18 and moves with it. The transmission slide tube 20 is slidably fitted on the other end of the transmission slide rod 19, and the outer side wall of the transmission slide tube 20 is fixedly connected to the opening and closing transmission block 16. When the transmission sleeve 18 moves upward, the transmission slide bar 19, the transmission slide tube 20 and the opening and closing transmission block 16 will drive the cover 10 to rotate around the hinge seat 11 to open the large end of the cover seat 9, so that the ventilation fan 6 can ventilate the internal cabin of the ship. When the transmission shaft 17 rotates in the opposite direction, the transmission slide bar 19, the transmission slide tube 20 and the opening and closing transmission block 16 will drive the cover 10 to rotate in the opposite direction around the hinge seat 11 to tightly fit the cover 10 on the large end of the cover seat 9 to prevent the seawater from flowing back into the internal cabin of the ship through the cover seat 9, the ventilation fan 6 and the bellows 4 after the ship tilts beyond a predetermined angle.

[0043] It should be noted that when the ship tilts beyond a predetermined angle, the seal cover 10 cannot be closed and blocked on the seal cover seat 9 by gravity, and the second seal cover opening and closing transmission member needs to be rigidly driven to complete the closing and blocking operation. Since the seal cover 10 is in an open state for a long time under normal use, the combination of flexible transmission and rigid transmission of the first seal cover opening and closing transmission member and the second seal cover opening and closing transmission member makes the opening and closing state of the seal cover 10 more reliable.
