Abstract

The invention provides an underwater rope cable length measuring device which comprises a base, an upper bottom plate, a front baffle plate, a rear baffle plate, a left baffle plate, a right baffle plate, a supporting frame, a drive wheel, a drive wheel shaft, a drive wheel shaft sleeve, a drive wheel supporting seat, an idler wheel, an idler wheel shaft, a locking nut, a magnetic coupling angle sensor, a sensor installing support, a support rib plate and a rope pressing mechanism. By adopting a mechanical mechanism with adjustable pressing force, idler wheel tensioning and drive wheel following and using a magnetic coupling technology, drive wheel rotating underwater non-contact detection is carried out, the rope cable releasing and winding length is calculated through measuring the rotation quantity, and the problems of high precision measurement and rotating shaft movable sealing of a deep water rope cable are mainly solved. The underwater rope cable length measuring device can be used for dynamically measuring the winding and releasing length of the rope cable in a process of winding and releasing the rope cable within a range of water depth of 1500-10000m.

Description

technical field [0001] The invention relates to a length measuring device, in particular to an underwater cable length measuring device. Background technique [0002] With the rapid development of the world economy, the development of marine resources has been paid more and more attention by various countries, among which the exploitation of marine oil and gas occupies a large proportion. In offshore oil and gas development and construction projects, it is usually necessary to connect two pipelines laid on the seabed. At this time, it is necessary to measure the relative distance and pose of the flange centers of the two pipelines. Prefabricate a section of transition pipe suitable for the connection of two pipes. The underwater cable length measuring device can measure the distance between two pipelines laid on the seabed, and belongs to the underwater pipeline measurement technology. [0003] Foreign companies mainly have three methods in underwater pipeline measurement:...
