Description

technical field [0001] The invention relates to the technical field of unmanned ships, in particular to a catamaran unmanned ship driven by multiple renewable energy sources with a torpedo-shaped submerged body. Background technique [0002] An unmanned ship is a new type of surface movement platform that navigates on the water surface autonomously or remotely and completes specific tasks under the remote monitoring of a base station on the ground or a mother ship control center. Even in the military field, unmanned ships play an important role. [0003] For a long time, manual collection has been the main means of offshore water quality sampling. Manual collection of offshore water quality in the usual sense means that sampling personnel arrive at designated sea areas by working ships and collect seawater samples with the help of sampling equipment. During the sampling process, personnel need to participate in the whole process on site, and the sampling cycle is long, whic...

Problems solved by technology

[0005] However, limited by traditional energy supply methods, the endurance of unmanned ships is far from meeting the needs of long-distance seawater sampling

Most of the existing water quality sampling unmanned ships are designed for small-scale waters such as inland rivers, lakes, and ports. The ships have small battery life (<10km), poor navigation performance, and cannot perform complex long-distance sea sampling operations. Further development of the human ship

When carrying out the overall design of traditional energy long-distance seawater sampling unmanned ships, there are complex phenomena of contradictions and multi-disciplinary coupling. In order to ensure the endurance of unmanned ships, it is necessary to increase energy sources such as increasing the number of lithium batteries or fuel storage. More hull layout space is required, which leads to an increase in the main dimensions of the hull, an increase in structural weight, and an increase in displacement, which in turn increases resistance, and increased resistance will lead to faster energy consumption, which is not conducive to the guarantee of endurance; even if the energy source is greater than the increase in energy consumption However, at this time, the hull weight and construction cost of the unmanned ship may be the same as that of a manned ship for manual collection, which violates the original intention of using unmanned ships for long-distance seawater sampling

The endurance of unmanned ships has become a technical bottleneck restricting the development of long-distance seawater sampling unmanned ships

[0006] In addition, the long-distance seawater sampling unmanned ship has a small displacement, is more sensitive to external disturbances such as wind, waves, and currents, and is prone to problems such as capsizing and yaw, and operates far away from the coast. Timely intervention will lead to property loss. Therefore, when designing an unmanned ship, it is necessary to consider the ship's stability, seakeeping, course stability, and self-righting ability. However, the existing unmanned ships for water quality sampling in small-scale inland waters often ignore this

Therefore, under the background that traditional battery technology or fuel engine technology is difficult to achieve revolutionary breakthroughs, research on the application of renewable energy in the design of long-endurance seawater sampling unmanned ships has excellent stability, seakeeping and heading stability. And the unmanned ship with self-righting ability has positive significance
