AI Technical Summary

Technical Problem

The optical protection components of existing marine lighting devices are prone to cracking in the high-salt and high-humidity marine environment, and the fixing methods are prone to corrosion, leading to maintenance difficulties and affecting safety and cost.

Method used

The device employs a combination structure of slide rod, spring, slider, cross block, rotating shaft, and limit block, which facilitates quick lens replacement. The springs buffer vibrations, and the sealing ring and support structure enhance the device's sealing performance and stability.

Benefits of technology

It enables convenient lens replacement, reduces the risk of breakage, improves the service life and safety of the device, and enhances sealing and corrosion resistance.

Abstract

The utility model relates to the technical field of lighting, and disclose a kind of lighting device for ship, be applied to shell, the left side of the shell is fixedly connected with the number of two slide bars.This lighting device for ship, with the advantages of being easy to replace, solves the optical protection component of ship lighting device generally adopts glass material lens, when it works long-term in the harsh environment of high salt and high humidity in ocean, faces two outstanding contradictions:one is that glass material itself is brittle, under the action of continuous ship vibration, sea wave impact or accidental collision, it is easy to break, affect sealing and lighting function, two is that its fixing mode is mostly dependent on metal bolt directly locked installation, although the structure is simple, but bolt is extremely easy to rust under the erosion of salt mist and moisture, leading to thread jamming or even breakage, so that routine maintenance or emergency replacement lens becomes extremely difficult, not only increase maintenance cost and time, more potential safety hazard to ship operation.
