A semiautomatic underwater topographic measurement device for small water areas is characterized in that a pull-up fixing rod with a fastening roove is provided with the fastening groove, an internalsliding clamp-groove fixing rod is provided with two winding devices and a roller device, and an integrated electric remote-control roller is composed of three rollers and an internal integrated circuit board, wherein two parallel rollers are arranged between upper and lower traction ropes, and the other roller is positioned below the two parallel rollers; the tail end of each traction rope is provided with a hook, and the hooks may be fastened to the fastening groove o the pull-up fixing rod with the fastening groove; one end of a measuring rope is connected to the roller device, and the other end of the measuring rope is fixed to a plumb; a cone of the plumb is split in the middle, forming two parts that are fixed in the top through a hinge, and the cone is emptied from the center. The semiautomatic underwater topographic measurement device for small water areas is simple to operate, high in data acquisition speed and high in site precision, is simple to manufacture, low in operationcost and high in production efficiency, and enables civil differences to be effectively relieved.
Description
【Technical field】 [0001] The invention relates to the technical field of topographic measuring devices, in particular to a semi-automatic underwater topographic measuring device for small water areas. 【Background technique】 [0002] Underwater topographic survey is a specific survey in engineering survey. It mainly measures the plane position and elevation of the bottom points of rivers, lakes and ponds, and is used to draw underwater topography to reflect the ups and downs of underwater topography. Underwater topographic surveying is different from land topographic surveying. It mainly faces difficulties such as difficult to locate measurement points, many measurement contents, and low measurement efficiency. Currently, conventional underwater topography is used to solve the problems of relatively shallow water depth and irregular shape in small water areas. Surveying method, echo sounding method, side-scan sonar method and other methods, underwater terrain surveying requir...
