[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figure 1-7, which is an embodiment of the utility model, provides an adjustable ventilation device for ships, the adjustable ventilation device for ships comprising a hull 1 and an installation box 2, the hull 1 is fixedly sleeved on the outer surface of the installation box 2, a ventilation pipe 4 is fixedly penetrated through the right side of the installation box 2, a disc 3 is arranged inside the ventilation pipe 4, the upper and lower ends of the disc 3 are rotated to penetrate the inner wall of the ventilation pipe 4, a friction wheel 5 is fixedly sleeved on one end of the disc 3 located above the ventilation pipe 4, a wind guide plate 15 is arranged on the right side of the disc 3, the wind guide plate 15 is fixedly inserted into the interior of the ventilation pipe 4, and the rear end of the ventilation pipe 4 is located at the friction wheel 5, the wind guide plate 15 allows the wind entering the ventilation pipe 4 to pass stably from one side of the axis of the friction wheel 5, so that the wind force stably pushes the disc 3 to rotate in one direction, and the wind guide plate 15 will not interfere with the rotation of the disc 3. The friction wheel 5 is located inside the installation box 2, and the outer surface of the ventilation pipe 4 and the right side of the friction wheel 5 are slidably connected with a movable ring 6, the movable ring 6 is located inside the installation box 2, and the interior of the installation box 2 and the front of the ventilation pipe 4 are fixedly inserted with a cross bar 12, the movable ring 6 is slidably connected to the outer surface of the cross bar 12, and the cross bar 12 prevents the movable ring 6 from rotating.

[0028] A corrugated hose 7 is fixedly installed at the right end of the ventilation pipe 4, and a wind collecting cylinder 16 is fixedly sleeved on the right end of the ventilation pipe 4 and located on the right side of the installation box 2. The corrugated hose 7 is located on the inner side of the wind collecting cylinder 16, and the inner diameter of the left end of the wind collecting cylinder 16 is smaller than the inner diameter of the right end thereof, and the inner diameter of the left end of the wind collecting cylinder 16 is larger than the outer diameter of the ventilation pipe 4. The wind collecting cylinder 16 increases the range of collecting wind, and at the same time, excess wind can be discharged from between the left end of the wind collecting cylinder 16 and the right end of the ventilation pipe 4. A rotating rod 9 is arranged on the inner side of the corrugated hose 7, and a plurality of rotating rods 9 are arranged, and the plurality of rotating rods 9 are distributed in a circular array around the axis of the ventilation pipe 4. The inner and outer rings of the end faces of the corrugated hose 7 are both wavy ring-shaped, so that the corrugated hose 7 can be easily removed. The right end of the tube 7 can be expanded and tightened, the right end of the rotating rod 9 is fixedly connected to the inner wall of the corrugated hose 7, the left end of the rotating rod 9 is fixedly connected to the right end of the ventilation pipe 4, and the left end of the rotating rod 9 is fixedly connected to a push spring 8 on one side close to the axis of the ventilation pipe 4, and the other end of the push spring 8 is fixedly connected to the right end of the ventilation pipe 4. The push spring 8 is curved in an arc shape, and an arc rod 14 is arranged on the inner side of the push spring 8. The left end of the arc rod 14 slides through the right end surface of the ventilation pipe 4, and the right end of the arc rod 14 is fixedly connected to the rotating rod 9. The push spring 8 has a tendency to push the right end of the rotating rod 9 away from the axis of the ventilation pipe 4, and the arc rod 14 enables the push spring 8 to stably extend and retract in an arc trajectory.

[0029] A pull rope 10 is fixedly connected to one side of the rotating rod 9 close to the axis of the ventilation pipe 4, and the other end of the pull rope 10 slides through the inner wall of the ventilation pipe 4. One end of the pull rope 10 located outside the ventilation pipe 4 is fixedly connected to the right side surface of the movable ring 6, and a track tube 13 is slidably sleeved on the outer surface of the track tube 13. The ventilation pipe 4 is fixedly sleeved on the outer surface of the track tube 13. The left end of the track tube 13 is a horizontal end, and the right end of the track tube 13 is an arc end. The track tube 13 limits the movable track of the pull rope 10. A friction plate 11 is provided at the rear contact of the friction wheel 5. The right end of the friction plate 11 is fixedly connected to the left side surface of the movable ring 6. The front side of the friction plate 11 and the outer ring surface of the friction wheel 5 are both uneven friction surfaces. The axis of the friction plate 11 is parallel to the axis of the ventilation pipe 4. When the friction wheel 5 rotates, the movable ring 6 is pulled to the left through the friction between the friction plate 11 and the friction wheel 5, and then the rotating rod 9 is pulled by the pull rope 10 to compress the push spring 8.

[0030] During use, when the wind force is relatively small, the push spring 8 has a tendency to push the right end of the rotating rod 9 to rotate toward the end away from the axis of the ventilation pipe 4, so that the right end of the corrugated hose 7 is opened, increasing the range of wind force entering the corrugated hose 7. The wind force entering the ventilation pipe 4 drives the disc 3 to rotate, and the disc 3 drives the friction wheel 5 to rotate synchronously. When the wind force increases, the disc 3 drives the friction wheel 5 to increase its speed, and then the friction force with the friction plate 11 increases the distance that the movable ring 6 moves to the left, and the rotating rod 9 is pulled by the pull rope 10 to rotate toward the axis side of the ventilation pipe 4. When multiple rotating rods 9 rotate, the right end of the corrugated hose 7 is retracted, so that the diameter between the right ends of the corrugated hose 7 is reduced. After the wind force increases, the diameter of the air inlet is reduced, thereby reducing the wind force entering the interior, effectively maintaining the stability of the air intake.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
