Description

Technical Field

[0001] The invention belongs to the technical field of ship electrical equipment, and in particular relates to a method for arranging multifunctional bulwark openings for polar scientific research. Background Art

[0002] The stern operation deck of the new deep-sea multifunctional research vessel is an important place for scientific research work, which is an important part of this type of ship. The design for personnel landing at the dock and boarding other ships is particularly important. However, unlike conventional ships, the main deck of the polar research vessel requires solid bulwark protection, so the bulwark openings for conventional use need to be considered to be detachable for boarding devices, but the pilot ladder and dock ladder fixings for conventional ship boarding do not need to be considered detachable; there is no need to set a gangway at the opening. Summary of the invention

[0003] In order to solve the technical problems in the prior art, the present invention provides a method for arranging openings of a multifunctional bulwark for polar scientific research, comprising the following steps:

[0004] Add lashing pads at the bulwark openings for installing removable lashing brackets and eye plates on dock ladders and pilot ladders;

[0005] A switchable porthole design is added to the bulwark. The porthole is closed when there are no passengers on board, and opened when there are passengers boarding or alighting.

[0006] Furthermore, the bulwark opening is located at the stern, and the number of the bulwarks is an even number, which are symmetrically arranged on both sides of the hull.

[0007] Furthermore, the upper end of the switchable porthole is flush with the outer plate.

[0008] Furthermore, when the porthole is in the open state, each of the bulwark openings is provided with two symmetrically arranged detachable handrails.

[0009] Furthermore, the bulwark opening is also provided with a detachable fastening soft ladder eye plate, and two detachable fastening soft ladder eye plates are symmetrically arranged on the outer side of the detachable handrail for connecting the pilot ladder.

[0010] Furthermore, the bulwark opening is also provided with a detachable dock ladder hanger, and two detachable dock ladder hangers are arranged on the bottom surface of the bulwark opening and away from the detachable handrails for connecting the dock ladder.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention mainly solves two major problems of ensuring the safety of personnel getting on and off and when no personnel are getting on and off at the bulwark opening of the stern operating deck of a new deep-sea multifunctional scientific research vessel; a fastening pad is added to the bulwark opening to be used for installing detachable fastening brackets and eye plates for dock ladders and pilot ladders; a switchable porthole design is added to the bulwark, and the porthole is closed in a sailing state without personnel on board; and the porthole is opened when personnel are getting on and off.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The present application proposes a method for arranging openings of a multifunctional bulwark for polar scientific research, comprising the following steps:

[0022] Add lashing pads at the bulwark openings for installing removable lashing brackets and eye plates on dock ladders and pilot ladders;

[0023] A switchable porthole design is added to the bulwark. The porthole is closed when there are no passengers on board, and opened when there are passengers boarding or alighting.

[0024] Reference Figure 1 The bulwark opening is located at the stern. There are four bulwarks in total, symmetrically arranged on both sides of the hull; the upper end of the switchable porthole is flush with the outer plate.

[0025] like Figure 2 and 3 , when there is no one waiting to board, the porthole is closed;

[0026] When the porthole is open, each bulwark opening is equipped with two symmetrically arranged removable handrails, which can be used in two working modes:

[0027] like Figure 4 and Figure 5 The bulwark opening is also provided with a detachable dock ladder hanger, and two detachable dock ladder hangers are arranged on the bottom surface of the bulwark opening and away from the detachable handrails, and are used to connect the dock ladder;

[0028] like Figure 6 and Figure 7 The bulwark opening is also provided with a detachable fastening soft ladder eye plate, and two detachable fastening soft ladder eye plates are symmetrically arranged on the outside of the detachable handrail for connecting the pilot ladder.

[0029] In summary, the above are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereto. All equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification are within the scope covered by the patent of the present invention.
