Surveying vessel for underwater topographic surveying and mapping

Abstract

The invention belongs to the technical field of engineering surveying and mapping auxiliary devices, and relates to a surveying ship for underwater topographic surveying and mapping. The surveying vessel comprises a surveying ship body, an anti-tipping mechanism, a water quality and water depth detection mechanism and an underwater topography boundary detection mechanism. A ship plate is arrangedon the surveying ship body; the water quality and water depth detection mechanism comprises a sealing assembly, a water sample collection assembly, a lifting square pipe and a lifting assembly, a sampling pipe is arranged in the lifting square pipe, and a sealing sliding sleeve is arranged at the bottom of the survey ship body; and the underwater topography boundary detection mechanism comprises an angle adjusting assembly, a mounting frame, a swing plate, a topography boundary detection sensor and a rotating cylinder. In the invention, an angle position of the topography boundary detection sensor can be further changed under the action of the underwater topography boundary detection mechanism; and a underwater depth is detected under the action of the water quality and water depth detection mechanism, water samples at different depths can be collected, and a situation that the ship body safety of the surveying ship body is affected due to the fact that the surveying ship body collideswith a submerged reef can be avoided.

Description

technical field [0001] The invention relates to the technical field of engineering surveying and mapping auxiliary devices, in particular to a surveying ship used for underwater terrain surveying and mapping. Background technique [0002] In the prior art, aerial photography is basically used for land surface topography measurement, and aerial photography cannot be used for underwater topography measurement. Usually, the underwater measurement methods are different according to different water areas. , In rivers and lakes with a small area of ​​calm water flow, the topographic map can be measured by using theodolite, electromagnetic wave rangefinder, ruler, etc. For rivers with fast-flowing water, other special methods are needed for measurement. Due to the size and draft of the ship, it is difficult for the ship to measure certain waters (such as shallow water near the coast, reef areas, etc.), which requires an unmanned survey ship to reduce the scale necessary for ship su...
