The invention belongs to the field of underwater robots, in particular to a sealing device for a dome window of a deep-sea camera, comprising a glass dome cover, a dome cover gland, a dome cover spacer, a sealing ring, a rectangular compensation ring and a lens group base The dome cover is sleeved on the rear end of the glass dome cover, and is threadedly connected with the front end of the lens group base, and the rear end of the lens group base is sealed and threaded with the camera cabin; A sealing ring is installed between the dome cover and the glass dome cover, and the rear end of the sealing ring extends between the dome cover and the front end of the lens group base, and is installed between the dome cover and the sealing ring A rectangular compensation ring is provided; a dome spacer is arranged between the bottom of the glass dome cover and the base of the lens group. The invention has the advantages of compact structure, high reliability, easy realization and the like.

Description

technical field [0001] The invention belongs to the field of underwater robots, in particular to a sealing device for a dome window of a deep-sea camera. Background technique [0002] The underwater camera is an important part for the underwater robot to complete the underwater observation and operation tasks. The viewing window (or observation port) is located in the front of the camera, which can protect the lens from the influence of the deep-sea environment. There are two basic types of windows: dome windows and flat windows. [0003] Due to the high refractive index of light in water, the refraction of light passing through the flat window at different angles greatly reduces the camera's field of view. Light rays pass through the surface of the dome window vertically without refraction, thereby eliminating the upper limit of the field of view. Therefore, for applications that require high-quality imaging, the use of dome windows can provide a wider field of view, prod...
