Description
Technical Field
The utility model relates to a carrying device, in particular to an underwater relative gravimeter carrying device.
Background
Marine gravimetry is one of the marine geophysical survey methods. The gravity measurement is based on Newton's law of universal gravitation as theoretical basis, and based on the premise of gravity change caused by density difference of various terranes forming crust and upper mantle, the gravity field value of the earth water area is measured by a special instrument, and the gravity abnormal distribution characteristics and change rules are given, so that the geological structure, crust structure, earth morphology, exploration of submarine mineral products and the like are researched.
There are two common approaches to existing marine gravimetry, one is to sink a gravimeter into the sea floor for remote measurement, i.e. for sub-sea gravimetry, which is similar to the measurement of gravity on land. Secondly, the gravimeter is arranged on a sea surface ship for observation, but the gravity observation value is influenced by various disturbances due to the influence of the movement of the measuring ship and the seawater. For the measuring device, the existing marine gravimeter has an absolute gravimeter and a relative gravimeter. The absolute gravimeter is used for measuring the absolute gravity value of one point, but the instrument has extremely large volume and no portability. The relative gravity instrument is small in size and good in portability.
The posture of the relative gravity instrument needs to be kept stable as much as possible in the using process, and the unstable posture can cause data misalignment and even damage to the instrument. At present, the relative gravimeter is fixedly installed with a submersible vehicle when in use, and the submersible vehicle adopts an energy source mode with a battery, so that the relative gravimeter cannot be kept static and stable for enough time after reaching the seabed, and the final measurement result is influenced.
Therefore, it is now necessary to improve the carrying structure of the existing relative gravimeter so as to ensure that the relative gravimeter can be stably placed in the water bottom for a long time and ensure the accuracy of the measurement result.
