TECHNICAL FIELD
[0001] The utility model relates to the field of shipbuilding, concretely relates to a marine self-closing barrier. BACKGROUND
[0002] Self-closing barrier is usually arranged at the personnel passage and opening of the ship to protect the personal safety. The marine self-closing device disclosed by Chinese patent CN216185909U includes a self-closing rod body and a vertical plate fixed to the first barrier. The left end of the self-closing rod body is sleeved with a welded pipe, and the right end of the self-closing rod body is provided with a polyethylene protective layer. A hinge opening is radially formed through the welded pipe and the left end of the self-closing rod body. The left end of the self-closing rod body is hingedly connected to the vertical plate through a hinge bolt passing through the hinge opening and the vertical plate, and nuts arranged at both ends of the hinge bolt. A horizontal stop plate is arranged at the top end of the vertical plate. When the self-closing rod body is rotated to the upper stop point, the self-closing rod body contacts the stop plate. At this time, the angle between the self-closing rod body and the horizontal plane is θ, and 85°<θ<90°.

[0031] The first elastic member 6 is a tension spring, and the second elastic member 14 is a spring in the embodiment. The pole 3 is rotationally connected with the upper end of the second balustrade column 2 through the shaft pin 7.
[0032] The working principle of the self-closing ship rail in the application is as follows:
[0033] When the self-closing ship rail is manually opened and closed, the pole 3 is manually rotated around the shaft pin to a suitable opening angle for personnel to pass through, and the tension spring 6 is stretched. When the personnel passes through the rail door, the pole 3 is quickly lowered into the clamping groove 13 of the first balustrade column 1 under the action of the restoring force of the tension spring 6 and the gravity of the pole 3.
[0034] When the self-closing ship rail is opened and closed by stepping on the pedal, the pedal assembly 4 is stepped on, the upper pedal 401 is rotated downward around the hinge 10, the second elastic member 14 is compressed, the pull rod 11 on the upper pedal 401 moves downward, the connecting member 5 drives the pull ring 12 at the end of the pole 3 to move downward, the pole 3 is rotated upward around the shaft pin, and at the same time, the first elastic member 6 is stretched. When the personnel passes through, the external force on the pedal 4 is removed, the upper pedal 401 is rotated upward around the hinge 10 under the action of the restoring force of the second elastic member 14, and the pull rod 11 on the upper pedal 401 moves upward. At the same time, the pole 3 is quickly lowered into the clamping groove 13 of the first balustrade column 1 under the action of the restoring force of the elastic member 6 and the gravity of the pole 3.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit them; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the specific embodiments of the present application can be modified or some technical features can be replaced by equivalent ones without departing from the spirit of the technical solutions of the present application, and all of them should be covered in the technical solution range of the present application.
