Submersible observation window

The observation window of a submersible will experience creep under high pressure environment, and its deformation degree is closely related to the compression time, external load, material properties, contact geometry, and lubrication state of the contact surface. Usually, the submersible observation window is designed with a 90 ° cone angle, which has excellent sealing and pressure resistance performance. This conical structure can effectively disperse pressure, reduce water flow resistance, thereby improving the durability of the observation window and the stability of the submersible.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The submersible observation window is a key component of deep-sea submersibles, whose core function is to provide deep-sea observation channels for divers, and resisting extreme high pressure in the deep sea is its core design requirement. In deep-sea environments, observation windows are easily affected by high pressure and undergo deformation. The degree of deformation is closely related to the compression time, external load size, material properties (mainly organic glass and titanium alloy), geometric contact form, and contact surface lubrication state. Therefore, scientific structural design and material selection are needed to ensure their compressive performance. To cope with the challenges of deep-sea high pressure, the observation window of deep-sea submersibles is usually designed as a conical structure with a 90 ° cone angle. The core scientific principle of this structure is to effectively disperse the enormous pressure brought by the deep-sea environment, convert the internal stress on the surface of the observation window into compressive stress, thereby significantly improving the pressure resistance of the window, avoiding damage caused by stress concentration, and enhancing the overall structural stability of the submersible. In addition, the conical design with a 90 ° cone angle can also reduce.
