Problems solved by technology

In this installation method, the window is not integrated with the bridge of the battleship, and the window is basically in a free state. Once it is subjected to the impact load of the battleship deck explosion or bullets, although the window will not be completely broken into small particles like tempered glass, but It is partially broken and deformed in the impact direction under the action of the impact and remains intact under the action of the internal colloid, but the overall bending deformation of the form is bound to occur, and at this time the outer dimension of the form will be smaller than the inner diameter of the frame
Therefore, the window may escape from the frame as a whole and fly into the cabin, causing casualties of the personnel in the cabin, and cannot play its due protective effect.
Although the RET holding value of the form (glass weight after explosion impact / glass weight before explosion impact) is larger than ordinary glass, it is always less than 1 and cannot be guaranteed to be equal to 1
[0004] In order to reduce the impact of the above-mentioned defects on the safety of personnel in the cabin, the height of the bridge window is usually raised during design, and no window will be opened at the lower part of the bridge, but this cannot completely guarantee that the bridge window of the battleship will not be completely closed in actual use. Affected by external shocks, it is impossible to guarantee the absolute safety of the personnel and equipment in the bridge cabin when the bridge window is subjected to external shocks
[0005] In addition, since the form and the bridge of the battleship are not integrated, there is a gap between the two. When the battleship is exploded or violently shaken, a rigid collision will inevitably occur between the form, which is a brittle material, and the rigid frame, resulting in The window itself first appears stress concentration or even cracks and loses its protective effect
[0006] The above-mentioned installation method and structure of the transparent window of the battleship bridge still have certain defects, and there are no targeted solutions and technical solutions. Therefore, related safety hazards always exist, and it has become a major problem that has always troubled relevant technical personnel.
[0007] However, with the progress of the times, the application of warships in national defense and other fields has become more and more common, but the core technology that can effectively improve the safety and convenience of the fastening support structure of the transparent window of the warship bridge has not yet been solved.
For such important issues that affect national defense construction and the safety of people's lives and properties, there is currently no reasonable solution, and the present invention fills the gap in this field

Embodiment Construction

[0052] The present invention will be further described below in conjunction with specific examples.

[0053] see Figure 1-2 , in the first preferred embodiment of a kind of battleship bridge window installation structure of the present invention, comprise an installation frame 1 and be fixed on the transparent window 2 of bridge main body 5 by installation frame 1 (explosion-proof glass can be selected for use Or bullet-proof glass, etc., not limited); the installation frame body 1 is formed with a first installation groove 10, and the side of the transparent window 2 is inserted in the first installation groove 10; and the side of the transparent window 2 is combined with a circle Frame body 3, a mutually cooperating installation structure is formed between the frame body 3 and the first installation groove 10. The frame body 3 includes a pressing component 31 and a fastening component 32, which are pressed by the cooperation of the pressing component 31 and the transparent ...

Abstract

The invention discloses a warship bridge window fastening structure. The warship bridge window fastening structure comprises an installation frame body and a transparent window fixed to a warship body through the installation frame body. A circle of prestressed structure frame body is arranged on the side edge of the transparent window in a combined mode, and fastening structure bodies which are matched are formed between the prestressed structure frame body and the installation frame body. A rigid frame body of a prestressed structure is arranged on the periphery of the transparent window in a combined mode, the transparent window is installed in cooperation with the bridge installation frame body through the rigid frame body, so that the window is prevented from integrally escaping from the installation frame body after being impacted by external force and deformed, and the safety performance of the window fastening structure is greatly improved. According to the warship bridge window fastening structure, an elastic buffering part and a sliding buffering part are adopted for playing a very effective buffering role immediately after the transparent window is impacted by explosion and the like, the breaking time can be obviously shortened after the window is impacted, the breaking probability can be obviously reduced after the window is impacted, and the safety protection performance of the whole warship bridge window structure is further improved.

Description

technical field [0001] The invention relates to various armed ships in national defense construction, in particular to a fastening structure and a fastening method for a transparent window of a warship bridge. Background technique [0002] Warships are generally a general term for military ships, that is, various military ships. In modern warfare, warships take on the roles of maritime offense and defense, maritime command, sea and land transportation, and sea surface launch platforms, etc., and have certain protection and firepower functions. Therefore, the bridge window of warships must also have corresponding protection capabilities. [0003] However, most of the current warship bridge window installation structures are bullet-proof glass or anti-riot glass and other windows embedded in a frame structure similar to a U-shaped groove, and sealant is provided around the perimeter, and some will seal against the metal edge on one side of the window. Perform flange fastening...
