Abstract

The invention discloses an aircraft for unmanned underwater topographic survey. The aircraft comprises a control part which comprises a closed cylindrical body, and a control panel and a power supplyassembly which are arranged in the cylindrical body, and a frame body which is a frame body formed by a plurality of sections of section bars; the frame body comprises a bottom frame and a first sideframe and a second side frame which are arranged on the two opposite sides of the bottom frame; a first top boundary beam is arranged at the top of the first side frame, a second top boundary beam isarranged at the top of the second side frame, the first top boundary beam and the second top boundary beam are parallel to each other, and a first cross beam, a second cross beam and a third cross beam are sequentially arranged between the first top boundary beam and the second top boundary beam; the cylindrical body is connected with the frame body through fixing pieces arranged on the first cross beam and the third cross beam respectively; the aircraft further comprises a buoy, a sonar assembly and a video acquisition assembly. The aircraft for unmanned underwater topographic survey providedby the invention is made of common sectional materials, has relatively small fluid resistance and is low in manufacturing cost.

Description

Technical field [0001] The invention relates to an underwater measuring equipment, in particular to an unmanned aerial vehicle for underwater topographic surveying. Background technique [0002] Underwater topographic survey is a specific survey in engineering surveying. It measures the plane position and elevation of rivers, lakes, reservoirs, harbors, and offshore bottom points to draw underwater topographic maps. One of the important content is water depth measurement. Water depth measurement generally uses sounding rods, sounding hammers, and sonar echo sounders. The bottom elevation is calculated based on the results of water depth measurement and water level observation. Finally, contour lines (or contour lines) are used to indicate the topography of the bottom . For water depth measurement, sonar echo sounders are now commonly used. They have the advantages of high accuracy and efficiency. The maximum sounding depth can reach 10000m. It has developed from single frequenc...
