Visual inspection device for automatic cable arrangement of electrically-driven marine winch

Abstract

The invention discloses a visual inspection device for automatic cable arrangement of an electrically-driven marine winch. The visual inspection device comprises a visual inspection camera, a guide rail, a gear and rack device, a camera servo motor, a camera servo driver, an image acquisition and processing module and a distributed light source group, The visual inspection camera collects the gapbetween cables wound on a cable storage reel in the cable arrangement process, the gap size serves as the feedback quantity to conduct automatic cable arrangement control, the visual inspection systemcan adjust the axial position and the radial position in a self-adaptive manner in the cable arrangement process, the dynamic calibration problem of the visual inspection camera is effectively solved, and therefore the cable gap visual detection precision is improved. The visual inspection device has the beneficial effects that the cable gap of the cable arranging quality is directly representedthrough visual detection, automatic cable arranging control is carried out by taking the cable gap as the feedback quantity, the phenomena of cable disorder and cable clamping in the cable arranging process are effectively avoided, the service life of the cables is greatly prolonged, and the safety of marine winch operation and marine equipment operation is greatly improved.

Description

technical field [0001] The invention belongs to a visual detection device, in particular to a visual detection device for automatic cable discharge of an electric-driven marine winch. Background technique [0002] With the rapid expansion of population, the depletion of land resources, and the deteriorating environment, countries around the world are focusing on the ocean, which is rich in oil, natural gas and mineral resources. The marine winch is the key deck mechanical equipment in the surface support system, mainly relying on the mother ship, it is widely used in the retraction and deployment of marine resource exploration and development equipment and its fixation in deep sea operations. In recent years, the exploration and development of marine resources has gradually shifted from the offshore to the deep sea. With the continuous increase of equipment operation depth, the cable of the marine winch is required to be super long, even reaching 10,000 meters. During the o...

AI Technical Summary

Problems solved by technology

Since there is no detection of physical quantities that directly represent the quality of the cable arrangement, and there are friction and wear, detection errors, and signal interference during the automatic cable arrangement process, once the cable arrangement deviates, the cable arrangement controller has no way of knowing it, and cannot realize automatic deviation correction. It can only be observed manually And intervene, implement manual correction

This poses a potential safety hazard to the operation of marine winches and marine equipment
