Problems solved by technology

[0003] (1) The frame-type protective bracket or structural frame can protect the observation window from the collision of large hard objects on the seabed, but cannot protect the collision of slender protrusions or fragmentary hard objects. However, the fact is that the collision of such small objects is becoming a threat carrier. The Main Factors of the Safety of the Observation Windows of Manned Submersibles
[0004] (2) Due to the addition of protruding frame-type protective brackets or setting the observation window in the structural frame, the distance between the outer surface of the observation window and the open water area is increased, and the distance between the observation window and the observed object is lengthened, which affects the observation effect

Embodiment Construction

[0018] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] This application discloses a full-coverage anti-collision protection device for the observation window of a manned submersible, please refer to figure 1 As shown in the sectional view, the anti-collision protection device is installed outside the observation window 1 of the manned submersible, specifically installed on the observation window penetration part 3 of the pressure-resistant structure 2 of the manned submersible, and the observation window 1 is arranged on the observation window penetration 3, so the anti-collision protection device is set outside the observation window 1 so as to provide full coverage protection for the observation window 1. The anti-collision protection device includes a connecting flange 4 , a bottom cavity structure 5 , a lower glass cover 6 , a bottom pressure balance liquid bag 7 and a bottom pressure...

Abstract

The invention discloses a fully-covered anti-collision protection device for an observation window of a manned submersible and relates to the field of manned submersibles. The device is arranged through a self structure, so that the pressure inside a cavity is balanced with the ambient pressure, therefore, the anti-collision protection device is in a normal stress state under a high-pressure environment, and can protect various hard objects from collision with the observation window in a high stress state within a wide range from all directions and perform omni-directional protection on the safety of the observation window; in the normal state, an observed object can be approached by a glass sealing cover on the collision protection device, so that an observation effect can be effectivelyenhanced.

Description

technical field [0001] The invention relates to the field of manned submersibles, in particular to a fully-covered anti-collision protection device for the observation window of the manned submersible. Background technique [0002] The transparent plexiglass observation window that can directly observe the environment outside the pressure-resistant structure with human eyes is a necessary standard configuration for deep-diving manned submersibles. In a large diving depth environment, the plexiglass of the observation window is in a state of high stress. Once it is hit by a hard object, it is easily damaged and damaged, causing serious consequences. At present, the traditional method is to add a frame-type protective bracket protruding from the observation window around the observation window or directly set the observation window in the structural frame for a certain degree of protection, but this protection method has the following problems: [0003] (1) The frame-type pro...
