Intelligent autonomous-operation gradiometer for land surveying and mapping

The invention relates to the technical field of land surveying instruments, in particular to an intelligent autonomous-operation gradiometer for land surveying and mapping, which comprises a shell, a bracket fixedly mounted in the shell, a pointer rotationally mounted in the middle of the bracket, and a dial, the first inner cavity is formed in the shell; the first groove is formed in the bottom of the shell; and the anti-skid mechanism is arranged in the first inner cavity and the first groove. Through the arrangement of the air cylinder, the first groove, the movable plate and other mechanisms, a worker puts the shell on the land, the pointer automatically deflects by a certain angle according to the inclination degree of the gradient, the worker records, air in the air bag enters the air cylinder under the driving of the driving mechanism, and the telescopic end of the air cylinder extends; the movable plate is driven by the air cylinder to move downwards, the cone at the bottom of the movable plate makes
