They are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0031] As Figures 1 to 6 shown, the present utility model provides a middle door mechanism for a ship, which includes a middle door main body 1, a transition plate 3 and a driving assembly 4. The first end of the middle door main body 1 is hinged to the main deck 2 of the ship's hull; the first end of the transition plate 3 is hinged to one of the middle door main body 1 and the main deck 2, and the second end of the transition plate 3 moves on the other of the middle door main body 1 and the main deck 2; the output end of the driving assembly 4 is connected to the second end of the middle door main body 1, and the transition plate 3 covers the hinge joint between the middle door main body 1 and the main deck 2; the driving assembly 4 drives the middle door main body 1 to rotate relative to the main deck 2 and drives the second end of the transition plate 3 to move.
[0032] By providing the transition plate 3, the hinge joint between the middle door main body 1 and the main deck 2 can be covered to avoid exposure, thereby ensuring the safety of personnel passing through and improving safety; and one end of the transition plate 3 can be hinged to one of the middle door main body 1 and the main deck 2 and movably connected to the other, so that when the driving assembly 4 drives the middle door main body 1 to open and close, it is not necessary to withdraw the transition plate 3, and it does not interfere with the normal opening and closing action of the middle door main body 1.
[0033] In some embodiments, the middle door main body 1 and the main deck 2 can be hinged through a hinge or a hinge shaft. The hinge structure of the hinge and the hinge shaft is prior art and will not be elaborated here. In the current embodiment, the middle door main body 1 is hinged to the concave structural plate at the side end of the main deck 2. And the transition plate 3 is an arc-shaped plate, and the arc-shaped plate can provide better support to avoid deformation during stepping and abutting against the middle door main body 1 and the main deck 2, causing interference. Further, gussets are provided on the concave surface of the arc-shaped plate to enhance the strength.
[0034] AsFigure 2 As shown, in some embodiments, two opposite first moving structures 5 are provided on the main deck 2, and two second moving structures 6 are provided on the side of the second end of the transition plate 3. The first moving structure 5 and the second moving structure 6 cooperate with each other to move. Thus, through the movement between the first moving structure 5 and the second moving structure 6, when the middle door body 1 is opened and closed, the transition plate 3 moves relative to the main deck 2. Exemplarily, the first moving structure 5 is a sliding groove, and the second moving structure 6 is a slider or a pulley, and the slider or the pulley slides in the sliding groove; the openings of the two sliding grooves are oppositely arranged, and the sliders or pulleys are arranged on the opposite sides of the transition plate 3, and the end of the sliding groove facing the middle door body 1 is rounded to avoid hard contact. In some alternative embodiments, the first moving structure 5 is a slide rail, and the second moving structure 6 is a slide seat. In some additional alternative embodiments, the first moving structure 5 is a sliding groove, and the second moving structure 6 is an aluminum round bar. The aluminum round bar is arranged at one end where the transition plate 3 is connected to the main deck 2, and both ends of the aluminum round bar protrude from the transition plate 3. The transition plate 3 slides in the sliding groove through both ends of the aluminum round bar, so as to move relative to the main deck 2. It can be understood that aluminum round bars can also be arranged at the end where the transition plate 3 is hinged to the middle door body 1, so that the transition plate 3 and the middle door body 1 are hinged through the aluminum round bars.
[0035] As Figure 2 shown, further, a first sensor 7 is provided on the side of the first moving structure 5 close to the first end of the middle door body 1. When the middle door body 1 is opened, the second moving structure 6 moves relative to it and can abut against the first sensor 7, that is, through the first sensor 7, the maximum moving distance of the second moving structure 6 in the maximum state when the middle door body 1 is opened can be sensed; it can be understood that the first sensor 7 can be connected to the driving assembly 4, so that the driving assembly 4 is driven to stop through the signal of the first sensor 7, avoiding excessive opening of the middle door body 1 and damaging the hinge or the hinge shaft. Exemplarily, the first sensor 7 can be but is not limited to a contact sensor.
[0036] As Figure 6As shown, it is understandable that, in some embodiments, the ship middle door mechanism further includes a second sensor 13, which is arranged on the first moving structure 5 and spaced apart from the first sensor 7, and the second moving structure 6 is located between the first sensor 7 and the second sensor 13, so that the moving distance of the second moving structure 6 on the other side is located by the second sensor 13, that is, the position of the second moving structure 6 when the middle door body 1 is in the closed state. Exemplarily, the second sensor 13 can have the same structure as the first sensor 7. In the current embodiment, in order to more accurately sense that the middle door body 1 is in the closed state, the second sensor 13 is arranged on the hull, and the second sensor 13 corresponds to the second end of the middle door body 1. When the middle door body 1 is closed, the middle door body 1 abuts the second sensor 13, thereby preventing the middle door body 1 from excessively abutting the hull when it is closed.
[0037] like Figures 3 to 5 As shown, the drive assembly 4 also includes a manual drive component 41 and an electric drive component 42. The manual drive component 41 and the electric drive component 42 are both connected to the second end of the middle door body 1. The manual drive component 41 and the electric drive component 42 respectively drive the middle door body 1 to rotate relative to the main deck 2, thereby avoiding the middle door body 1 being unable to be opened by the electric drive component 42 in an emergency state such as power outage. In some embodiments, in order to allow the manual drive 41 and the electric drive 42 to control the middle door body 1 respectively, the ship middle door mechanism also includes a pulley group and a connecting rope 11, wherein the pulley group includes a plurality of first pulleys 8 and a second pulley 9, a first pulley 8 is provided at the opposite ends of the second end of the middle door body 1, and a plurality of second pulleys 9 are provided on the hull, one end of the connecting rope 11 is connected to the output end of the electric drive 42, and the other end of the connecting rope 11 first passes through one of the first pulleys 8 at the second end of the middle door body 1 to the second pulley 9 of the hull, and guides the connecting rope 11 to the other side of the middle door body 1 through a part of the second pulley 9, and then passes through another first pulley 8 at the second end of the middle door body 1, and guides the connecting rope 11 to another part of the second pulley 9 again and connects to the output end of the manual drive 41, and then the middle door body 1 can be driven to open and close by the manual drive 41 or the electric drive 42. It can be understood that the distribution of the second pulley 9 on the hull is not specifically limited. Exemplarily, the electric drive member 42 may be a motor, a rope wheel is provided at the output end of the motor, and one end of the connecting rope 11 is connected to the rope wheel. Furthermore, the manual drive member 41 is a manual winding wheel, which is connected to the hull, and the other end of the connecting rope 11 is connected to the manual winding wheel; and in order to prevent the manual winding wheel from rotating unexpectedly, a locking device 10 is also provided on the hull, and the locking device 10 is connected to the manual winding wheel so that the manual winding wheel can be locked or unlocked by the locking device 10. It should be noted here that the locking device 10 can adopt the existing technology, and its specific structure will not be repeated.
[0038] As Figure 2 and Figure 6 shown, in some embodiments, sealing portions 12 are provided around the hull corresponding to the middle door body 1. Thus, when the middle door body 1 is closed, the middle door body 1 abuts against the sealing portions 12 on the hull, thereby sealing the gap between the middle door body 1 and the hull and improving the airtight performance. It should be noted here that the sealing portions 12 can be, but are not limited to, sealing components such as rubber.
[0039] In some embodiments, a movable plate 14 is hinged to the second end of the middle door body 1. The thickness of the movable plate 14 gradually decreases from the end close to the middle door body 1 to the end far from the middle door body 1. That is to say, the longitudinal section of the movable plate 14 is triangular. Thus, when the second end of the middle door body 1 is placed on the dock, the movable plate 14 can rotate relative to the middle door body 1 by a certain angle and then abut against the dock, which can reduce the height difference between the middle door body 1 and the dock and facilitate the close transition connection between the middle door body 1 and the dock.
[0040] As Figure 3 and Figure 4 shown, in some embodiments, railings 15 are provided on both sides of the middle door body 1 adjacent to the movable plate 14. Exemplarily, the railings are retractable railings. When the middle door body 1 is opened, the railings can be retractably opened to the maximum at the same time, avoiding too large a gap with the outer hull plate. The railings are convenient for people to hold by hand, further improving safety. The retractable railings are prior art and will not be elaborated. Further, an anti-slip layer is provided on the upper end surface of the middle door body 1 to avoid slipping in a water-rich environment. Exemplarily, the anti-slip layer is an anti-slip sand layer.
[0041] The present utility model also provides a ship, which includes a hull and the above-mentioned ship middle door mechanism. The first end of the middle door body 1 of the ship middle door mechanism is hinged to the main deck 2 of the hull. Thus, the hinged portion between the middle door body 1 and the main deck 2 is covered to avoid exposure, thereby ensuring the safety of personnel passing through and improving safety.
[0042] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
