Shore balance fixing device for hydrographic survey instrument

The utility model relates to the technical field of hydrographic survey instrument fixing, in particular to a shore balance fixing device for a hydrographic survey instrument, which comprises a mounting seat, a support rod mounted at the top end of the mounting seat, a support plate mounted on the surface of the support rod, and an adjusting plate mounted at one end of the support plate. When the hydrographic survey instrument body is influenced by rising and falling of the tide, water flow and wind power, the floating plate and the hydrographic survey instrument body on the floating plate are kept balanced and stable through the connecting rod and can rise or fall on the water surface along with rising and falling of the tide, and balance and stability of the hydrographic survey instrument body are kept. When the hydrographic measuring instrument body is placed in water for use, the hydrographic measuring instrument body can be rotated in water and the measuring position can be adjusted, and the measuring po
