Problems solved by technology

Moreover, due to the cantilever structure, the load-bearing effect is poor. If the butt sleeve is extended downward, the bending moment brought to the main structure will be larger during impact, which is not conducive to the dissipation of the impact load. This requires an additional height difference between the two sleeves. compensate

Abstract

Provided is an underwater robot monitoring auxiliary device. The device comprises a cylindrical shell, guide rails, a bearing column, a stop plate, a connecting strip and a butt sleeve, wherein the cylindrical shell is nested inside the butt sleeve; the cylindrical wall of the cylindrical shell is provided with a notch; the two ends of each guide rail are mounted onto the inner wall of the butt sleeve and each guide rail passes through the notch in the cylindrical wall of the cylindrical shell; the bearing column is arranged at the bottom of the cylindrical shell; one end of the stop plate is mounted onto the top of the butt sleeve; one end of the connecting strip is fixed onto the inner wall of the cylindrical shell; and the other end of the connecting strip is fixed onto the outer wall of the butt sleeve. An observation cylinder is additionally arranged inside the butt sleeve so as to facilitate the observation of a robot through the ejected observation cylinder; at the same time, a better opportunity is provided for putting down a conduit rack so that the robot is prevented from walking back and forth in water for observing whether two guide posts enter the butt sleeve of the conduit rack correctly, and accordingly the sitting opportunity of the conduit rack is not missed.

Description

technical field [0001] The invention relates to a monitoring device, in particular to an auxiliary monitoring device for an underwater robot used in the underwater docking process of a jacket sleeve and a base plate guide pile. It belongs to the field of marine engineering technology. Background technique [0002] With the development of marine technology, human activities in deep water are becoming more and more frequent. Due to its special working environment, the safety of deep water activities has also received much attention. Underwater docking operation is a major task in deep water activities. [0003] At present, the docking of the jacket and the guide pile of the foundation plate in the sea is related to the selected offshore oilfield development plan, and there are mainly two development plans that will implement this docking: [0004] One is: pre-drilling wells; the other is: to retain exploration wells with mining value. Among them, the pre-drilling scheme is ...
