Description

Technical Field

[0001] The utility model belongs to the field of underwater topography measurement, and in particular relates to an integrated survey ship suitable for offshore topography measurement. Background Art

[0002] As the development and utilization of marine resources have attracted increasing global attention, offshore topographic survey technology has also developed rapidly. The emergence of survey ships has provided a new solution for offshore topographic survey. This new type of survey ship can use advanced technology to complete the tasks of underwater topographic survey, seabed geomorphology analysis, and hydrological and meteorological monitoring, and improve the accuracy and efficiency of underwater measurement.

[0003] Traditional measurement methods mainly rely on small manually operated survey ships or submersibles. These methods are limited by manpower, material resources and time factors, have a limited measurement range, and are difficult to guarantee accuracy. At the same time, due to the influence of natural factors such as wind, waves and tides, the measurement process is often full of difficulties.

[0004] In response to the above problems, Chinese patent CN202311444398.3 discloses an unmanned boat for underwater topography measurement. A power paddle and a detector are arranged at the bottom of the measuring hull, and a drainage propulsion mechanism is arranged to separate floating objects to the two sides of the measuring hull, so that the guide plate can be continuously opened and closed to the outside for reciprocating operation, which is convenient for pushing away the floating objects on both sides and facilitating the movement of the measuring hull. At the same time, the extracted liquid can be continuously discharged to the outside, thereby achieving the propulsion of the measuring hull and reducing energy consumption. The hull self-balancing mechanism can be used to achieve the balance of the movement of the measuring hull. In addition, corresponding solar photovoltaic panels can be installed on the photovoltaic panel mounting frame to facilitate photovoltaic power generation processing. The pitch adjustment mechanism can drive the installed photovoltaic panels to flip and pitch adjust, which has the advantages of convenient measurement and travel, good stability and energy-saving use.

[0005] However, the above-mentioned unmanned boat for underwater topography measurement cannot realize the real-time and accurate acquisition of topographic information below the sea surface by using sensors and data processing systems, and the equipment of the above-mentioned device is relatively scattered, difficult to maintain, and occupies a large space; in the offshore area, an unmanned boat for underwater topography measurement cannot accurately measure and has difficulty in flexible adaptability under different terrains.
