Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a multi-axis sensor installation mechanism applied to an ocean platform. Background Art

[0002] There are two main forms of multi-axis sensor installation at home and abroad. One is to place a beam on a hard surface and install the multi-axis sensor in the groove of the beam. The other is to drill a well from the hard surface of the bottom of the water and attach a protective casing, and then place one or two multi-axis sensors in the protective casing. Both of the above forms require additional measures to adjust the depth and direction, and auxiliary means are also required to ensure the installation direction. At present, in order to ensure that the offshore platform is firm and reliable, its support beam structure is not perpendicular to the sea level. Because the wiring flange cabin is vertically welded to the support beam structure of the offshore platform, the wiring flange cabin cannot be orthogonal to the main body of the offshore platform. However, the current installation method of multi-axis sensors is complex in structure and it is not easy to adjust the orthogonality of the multi-axis sensor and the offshore platform benchmark, which in turn affects the error and accuracy of the multi-axis sensor data collection.
