Abstract

The invention discloses an anchor chain sensor fixture based on permanent magnetic chuck adsorption and applied to an ocean platform. The anchor chain sensor fixture comprises a loading-unloading handle (1), a hinge A (2), a hinge B (3), crank connecting rods A (4), hinges C (5), crank connecting rods B (6), a NdFeB-CoNiAl permanent magnetic chuck (7), a fixture frame (8), sensor fixing loops (9) and sensors (10). The anchor chain sensor fixture disclosed by the invention has the advantages that the mounting mode is simple and effective; the fixing effect is tight; the working requirements of the sensors are met; the mounting action is simple; and the underwater unmanned operation can be performed by an ROV.

Description

technical field [0001] The invention relates to an anchor chain sensor fixing fixture for an ocean platform based on the adsorption of a permanent magnetic sucker and an installation method thereof. Background technique [0002] In the production process of the offshore platform, the mooring positioning system is widely used, and the mooring positioning system ensures the normal and safe work of the offshore drilling platform. The situation in the deep sea is complex and unpredictable. The anchor chain is easy to break due to excessive force in the deep sea, resulting in very serious consequences. Therefore, it is very important to monitor the motion state of the anchor chain. [0003] In actual production, self-contained acceleration sensors and self-contained inclination sensors are often used to monitor the motion state of anchor chains. There can be no relative movement between the sensor clamp and the anchor chain. The sensor clamp should be tightly attached to the ...
