Overwater surveying and mapping device for ocean engineering surveying and mapping

Abstract

The invention discloses an overwater surveying and mapping device for ocean engineering surveying and mapping, and belongs to the technical field of flow measurement. The device comprises a surveyingand mapping ship body, detection equipment, a propeller and a power supply for supplying power to all electrical elements, and an obstacle avoidance element, an anti-winding element and an anti-tipping element are arranged on the surveying and mapping ship body. Through the detection equipment, the detection of the ocean current flow velocity in a shallow water environment and a deep sea water area can be met, and relevant parameters are obtained, so the marine condition can be known conveniently, the application range of the detection equipment is greatly expanded, and the detection equipmentis widely applied to various application occasions such as water transportation safety guarantee and underwater navigation and positioning and has the advantages of being accurate in measurement, stable in operation, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of flow measurement, and in particular relates to an above-water surveying and mapping device for marine engineering surveying and mapping. Background technique [0002] With the increasing demand of human beings for natural resources, scientific research and resource investigation have also extended from the land to the ocean, which accounts for 70% of the earth's surface. An important part of the technology, its technical difficulty and precision requirements are getting higher and higher. The measurement accuracy of wind, waves, currents and other marine environments directly determines the accuracy of ocean engineering experiments. [0003] Long-term, continuous, and fixed-point detection of the marine hydrological environment, especially the real-time detection of a series of marine hydrological parameters such as seabed depth, seawater density, and current velocity, is a difficult, complex and signifi...

Problems solved by technology

[0004] Many universities and units at home and abroad have conducted research on devices for measuring flow parameters, developed a series of products and put them into use, but there are still many deficiencies, most of which are only suitable for shallow water environments, or have a single structure and function. However, there is a lack of in-depth research on devices that can be applied to deep-sea high pressure. At the same time, when the existing marine water body surveying and mapping devices are working, they are easily entangled with plants or impurities in seawater, which affects the normal navigation of the device. At the same time, when obstacles appear on the opposite side It is easy to damage the device and reduce its service life. When the waves impact the device body, it is easy to roll over. The detection element is easy to deviate from the horizontal position with the inclination of the device body, and cannot send signals to the sea surface vertically and receive signals. , which can easily lead to data bias
