The invention provides a seabed miniature earthquake sensor carrying platform by aiming at the problem that a miniature earthquake sensor lacks a carrying structure capable of keeping the miniature earthquake sensor horizontal all the time. The carrying platform adopts a spherical inner packaging structure and a hollow outer packaging structure, the miniature earthquake sensor which needs to be carried is put in the inner packaging structure, and then, the inner packaging structure is put in the outer packaging structure full of silicone oil; on the basis of the dynamic equilibrium principle of a tumbler, the inner packaging structure finally can keep an upward and horizontal state no matter how the attitude changes; and therefore, a sealing and anti-corrosion working platform which is suitable for the seabed environment and guarantees that the sensor is always under a horizontal state is provided for the miniature earthquake sensor and relevant electronic devices thereof. The seabed miniature earthquake sensor carrying platform disclosed by the invention has the advantages of simple structure, reliable performance, small volume, low cost and the like.
Description
technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a submarine micro-seismic sensor carrying platform. Background technique [0002] The submarine seismograph is an important tool for people to study the seabed structure and detect seabed resources. The submarine seismic sensor carrying platform is an important part of the submarine seismograph. Its function is mainly to provide a safe, A stable operating environment provides a working environment for sensors with direction requirements to keep them in a horizontal state. [0003] When testing the seabed vibration signal, the seabed vibration signal is transmitted to the shell of the seismic sensor carrying platform in contact with it through the seabed ground, and then transmitted to the seismic sensor mounted therein through the internal structure of the seismic sensor carrying platform, the sensor collects the vibration signal, and Transmission via cable or wirele...
