Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of ship design, and in particular relates to an impact-resistant camera bracket for ships and an anchor chain operation monitoring system. Background Art
[0002] Ships come in a variety of shapes, and their appearance needs to be designed to suit specific purposes. For ships with large bow lines, it is impossible to set up a suitable observation hole on the deck to observe the retraction and deployment of the anchor chain. Therefore, a camera solution is used to compensate for the line of sight. The bow waves are too large, so the camera is usually lowered when anchoring and reeling in, and retracted when sailing. Based on this, a bracket with adjustable camera height is designed to facilitate the deployment and retrieval according to the working conditions.
[0003] Therefore, how to provide an impact-resistant camera bracket and anchor chain operation monitoring system for ships to solve the problems of insufficient impact resistance, low adjustment efficiency and poor compatibility of camera brackets in the existing technology has become a technical problem that needs to be solved urgently.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0024] Traditional marine camera mounts suffer from insufficient impact resistance, low adjustment efficiency, and poor compatibility. The lack of impact resistance refers to the tendency of ordinary bolts to loosen under surge impact, causing camera deviation. The low adjustment efficiency is reflected in the short adjustment stroke (typically ≤0.5m) of the single-tube structure and the need for specialized tools. The poor compatibility is primarily due to the fixed mounting holes, which only accommodate specific camera models.
[0025] In an embodiment of the present invention, a height-adjustable camera bracket device includes: round steel, a round plate, a stainless steel clevis bolt, and a nut assembly. The round tubes are fixed with the clevis bolts to achieve adjustment of the camera height.
