BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of the present invention;

[0015] Figure 2 It is a structural schematic diagram of the check valve and the gravity valve disc. DETAILED DESCRIPTION

[0016] like Figure 1 and Figure 2 As shown, in this embodiment, the present invention includes a wind tube 1 and a protective component 2, the bottom of the wind tube 1 is connected to the cabin, the protective component 2 is arranged on one end of the wind tube 1, a check valve 3 is provided between the wind tube 1 and the protective component 2, a gravity valve disc 4 matched with the check valve 3 is hinged on one end of the check valve 3 close to the protective component 2, a sealing gasket 5 is provided between the gravity valve disc 4 and the check valve 3, and an opening 6 is provided at the bottom of the protective component 2, and the cross section of the opening 6 is parallel to the horizontal plane.

[0017] It can be seen from the above scheme that the combination of the wind tube 1 and the protective assembly 2 is a gooseneck structure, and the bottom opening 6 of the wind tube 1 is connected to the cabin. Under normal working conditions, the gravity valve disc 4 opens downward, and ventilation is performed after being protected and filtered by the insect-proof net 8 and the filter net 10. The gravity valve disc 4 itself has a certain weight. When the device flips over with the self-righting ship, the gravity valve disc 4 itself is affected by gravity, flipped onto the check valve 3 and pressed against the sealing gasket 5 on the check valve 3, playing a sealing role to prevent external seawater from entering. If the external seawater impacts the gravity valve disc 4 during flipping, the pressure of the gravity valve disc 4 on the sealing gasket 5 increases, and the sealing performance increases at the same time.

[0018] A preferred solution is, Figure 1 As shown, the protective component 2 includes a tube body 7 and an insect-proof net 8, the opening 6 is arranged on the bottom of the tube body 7, the insect-proof net 8 is arranged on the bottom of the tube body 7, and the insect-proof net 8 and the tube body 7 are detachably connected; the air duct 1 is connected to the protective component 2 through a flange 13, a sealing ring 14, a bolt 15 and a nut, and the check valve 3 and the gravity valve disc 4 are clamped between the air duct 1 and the protective component 2.

[0019] It can be seen from the above scheme that the insect-proof net 8 is detachably connected. By disassembling the insect-proof net 8 and cleaning dust and insects in time, the air quality in the ventilation duct is effectively guaranteed.

[0020] A preferred solution is, Figure 1 As shown, an exhaust fan 9 is provided on one end of the air duct 1 which is connected to the cabin, and the exhaust fan 9 and the air duct 1 are detachably connected; a plurality of filters 10 are provided on one end of the air duct 1 close to the exhaust fan 9, and a plurality of through holes are opened on the filter 10; the number of the filter 10 is at least two, and the through holes between two adjacent filter screens 10 are arranged in a staggered structure; a valve 11 is provided on the bottom end of the air duct 1 close to the cabin, and the valve 11 adopts one or a combination of a mechanical valve or a solenoid valve; the valve 11 adopts a solenoid valve or a combination of a mechanical valve and a solenoid valve, and the protective component 2 is provided with a sensor 12 which cooperates with the gravity valve disc 4, and the sensor 12 is connected to the valve 11 with an electrical signal.

[0021] It can be seen from the above scheme that when the sensor 12 recognizes and detects that the gravity valve 11 is attached to the check valve 3, the sensor 12 sends a signal to the background, and the background controls the solenoid valve to close the channel in the air duct 1 to prevent seawater from entering. Combined with the structure of the check valve 3, a double protection effect is achieved; the exhaust fan 9 is provided to accelerate the circulation of air in the cabin. Combined with a number of the filters 10, the quality of the air in the air duct can be effectively guaranteed, and at the same time, dust can be effectively prevented from clogging the valve 11; the filter 10 and the air duct 1 are detachably connected, which is convenient for disassembling and cleaning the filter 10.
