Description
Technical Field
The invention relates to the technical field of watertight doors, in particular to a large hinge type watertight door.
Background
Watertight doors are most commonly used in ships, but also in gates for reservoirs, rivers, ditches etc. The opening and closing modes of the watertight door can be divided into: the door is hinged, translational (sliding, rolling), rolling and the like, wherein the hinged watertight door is the most common watertight door form, and can be applied to various occasions like a household door. The small-sized hinged door has the biggest characteristics of simplicity, reliability, small size and light weight of a common door, and the opening direction of the common door is vertical to the doorframe, so that the space position for opening the door in a rotating way is required to be arranged in the direction vertical to the doorframe, and the small-sized hinged door can be opened and closed by manual operation. The translation type watertight door can be divided into a vertical moving type and a transverse moving type according to the structure, is generally applied to passenger cabins and cargo holds of ships, gates of reservoirs, riverways, ditches and the like, and has the biggest characteristics of complex mechanism, large size and heavy weight, the opening direction is parallel to a door frame, the space position for accommodating the opened door is required to be arranged in the direction parallel to the door frame, and the operation mode of the translation door can be divided into a manual operation mode and a power operation mode. In summary, when there is no space for accommodating the horizontally-sliding door in the direction parallel to the doorframe and a space for accommodating the rotatably-opening door in the direction perpendicular to the doorframe, the large watertight door can only be opened and closed in a hinge-type manner to satisfy the requirements for watertight and space positions.
In the prior art, the size of the watertight door and the watertight compression degree have a close relation, the far-end watertight compression strip of the small-size door can compress the small-size sealing rubber strip, but the far-end watertight compression strip of the large-size door cannot compress the sealing compression strip. As shown in fig. 6, when the small door 20 starts to close with the door support 22 as the rotation axis, it is obvious that the small watertight bead 23 closest to the door support 22 will press the small sealing rubber strip 24 first, that is, the smaller the distance from the center of the circle of the door support 22, the longer the arc length, the later the small sealing rubber strip 24 is pressed. And as the door body 1 continues to rotate around the door body support 22, the far small watertight pressing strip 23 is gradually pressed on the small sealing rubber strip 24. Due to the elastic characteristic of the small sealing rubber strip 24, the small sealing rubber strip 24 is difficult to compress by the small watertight pressing strip 23 which is farther away from the door body support 22, and when the distance between the small watertight pressing strip 23 and the door body support 22 reaches a certain critical value, the small sealing rubber strip 24 cannot be compressed by the small watertight pressing strip 23, so that the watertight requirement cannot be met. For the small-sized hinge type watertight door, because the size of the watertight door is small, the distance between the farthest small watertight pressing strip 23 and the door body support 22 does not reach a critical value, and although the degree of pressing the near small watertight pressing strip 23 by the far small watertight pressing strip 23 is inferior, the watertight effect can still be ensured. The critical value is that the farthest small watertight bead 23 can effectively compress the small sealing rubber strip 24, and the door size meeting the watertight requirement is satisfied.
In summary, when the distance between the small watertight pressing strip 23 and the door body support 22 reaches the critical value of 1.5m, the existing design method of the small hinge type watertight door cannot meet the requirement of watertight design of the watertight door, and a new watertight design method must be adopted to meet the requirement of watertight design according to the watertight design characteristics of the large hinge type watertight door.
