AI Technical Summary

Technical Problem

When working on the seabed, the marine magnetometer is easily touched by sharp reefs and entangled by mesh ropes, resulting in damage. It is necessary to maintain a depth of 1-2 meters on the seabed surface when detecting special communication submarine cables and objects, and the reflected signal strength is insufficient.

Method used

A marine magnetometer protective cover was designed, including a cesium optical pump magnetometer and a protective case. The protective case was equipped with notched frame brackets, support beams, counterweight strips, fixing hoops, handle hollow grooves and magnetic instrument handles. Custom-made connectors and bolted connections, using polypropylene pure sheets and engraved threaded connections, limit slots, slots, sliders and top springs for easy installation and fixation of handles.

Benefits of technology

Through the design of the protective cover, the stable installation and fixation of the marine magnetometer handle is achieved, avoiding touch and winding damage, and improving signal strength and working stability.

Abstract

The utility model relates to the field of magnetometers, in particular to a marine magnetometer protection cover. Comprising a cesium optical pump magnetometer and a protective shell, the protective shell is installed on the surface of the cesium optical pump magnetometer, a notch frame support and a supporting beam are installed in the protective shell, the supporting beam is connected with the notch frame support, four balance weight strips are installed on the surface of the protective shell, fixing hoops are installed at the two ends of the protective shell, and the fixing hoops are connected with the notch frame support. A carrying handle hollowed-out groove is formed in the protection shell, a magnetometer carrying handle is arranged in the carrying handle hollowed-out groove, and a magnetometer connecting cable, a transmitting window groove and a magnetometer transmitting sensor are installed in the cesium optical pump magnetometer. The marine magnetometer protection cover provided by the utility model has the advantages that the marine magnetometer can work smoothly on the seabed surface, and meanwhile, the marine magnetometer is prevented from being touched by sharp reefs and wound by net ropes.
