Abstract

The invention provides a marine gravimeter stabilizing platform, which belongs to the field of marine gravity measuring equipment. The marine gravimeter stabilizing platform comprises a pedestal, a frame and a bracket, wherein an accommodating cavity is formed in the pedestal, the frame is connected in the accommodating cavity in a rotated manner, a first motor used for driving the frame to rotate is arranged on the pedestal, the bracket is connected in an empty cavity enclosed by the frame in a rotated manner, a second motor used for driving the bracket to rotate is arranged on the pedestal, and a rotating axis of the frame relative to the pedestal is vertical to a rotating axis of the bracket relative to the frame. The marine gravimeter stabilizing platform adopts the structure combining the pedestal, the frame and the bracket, and the frame and the bracket can rotate around axes in different directions, thereby eliminating angular motion such as pitching and rolling of carries including steamships and the like, keeping a sensor of a marine gravimeter parallel to an earth vertical line always, ensuring measuring precision of the marine gravimeter, and compensating for deficiencies in the prior art.

Description

technical field [0001] The invention relates to the field of marine gravity measuring equipment, in particular to a stable platform of a marine gravimeter. Background technique [0002] Marine gravimeters are gravimeters used on ships or inside submarines. Under the condition of constant speed and straight line sailing in the ocean, the gravity measurement is carried out continuously. Since the instrument is placed on the moving hull, it is greatly affected by the vertical acceleration and horizontal acceleration and the tilt of the base. Therefore, the entire gravimeter is usually placed on a stable platform. The main function of the stable platform is to isolate the pitch and roll equiangular motions of ships and other carriers, so that the sensor of the marine gravimeter is always parallel to the vertical line of the ground and is not affected by The effect of horizontal acceleration, thereby improving the measurement accuracy of marine gravimeters. [0003] However, mo...
