Problems solved by technology

Most of the existing underwater vehicles are designed as cylinders, similar to torpedo shapes, but the roll stability is insufficient, and they are easily disturbed by water flow during underwater detection tasks, resulting in fluctuations in the collected data and affecting the accuracy of data collection; moreover, Most of the internal design is chaotic, it is difficult to better meet the needs of improving the utilization of internal space, wiring and sealing are difficult, disassembly and maintenance are cumbersome, low efficiency, low navigation accuracy, low level of independent decision-making, weak reliability and battery life And other issues

Embodiment 1 Embodiment 1 Embodiment 2

[0120] The above is the first embodiment of a flat underwater vehicle provided by the embodiment of the application, and the following is the second embodiment of a flat underwater vehicle provided by the embodiment of the application. For details, please refer to figure 1 , Figure 29 to Figure 31 .

[0121] Based on the technical solution of the first embodiment, the second embodiment is a further description of the control system:

[0122] Further, taking two independent cabins 3 as an example, they can be installed in the rigid frame 2 in parallel and side by side, which is not specifically limited.

[0123] like Figure 20 As shown, as far as the control system is concerned, it includes a master control module 100, a slave control module 200, a communication module, a communication interface conversion module 8, an information exchange module, an underwater information acquisition module, a control battery pack (not shown in the figure), and a power Battery pack (not s...

Embodiment 3

[0158] The above is the second embodiment of a flat underwater vehicle provided by the embodiment of the application, and the following is the third embodiment of a flat underwater vehicle provided by the embodiment of the application. For details, please refer to figure 1 , Figure 29 , Figure 32 to Figure 37 .

[0159] Based on the solution of the second embodiment above, the third embodiment is a further description of the navigation and positioning matching system:

[0160] From the aspect of navigation, the applicant has found that the existing underwater vehicle navigation and positioning technology adopts a preset, relatively inherent and rigid combined navigation method, which not only cannot be accurately applied to various tasks, but also greatly reduces the underwater vehicle. In order to solve the problem of the autonomous decision-making level and endurance capability of the aircraft, the applicant has improved the navigation and positioning matching system, so...

Abstract

The application discloses a flat underwater vehicle, which includes a carrier, a control device and a propulsion device. The carrier is an overall flat horizontal hexagonal prism-like shell; the hard frame is detachably installed in the shell; at least two independent cabins can be detachably installed in the hard frame; the propulsion device is installed in the shell. The control device includes a control system and a navigation and positioning matching system; the navigation and positioning matching system is used to match the navigation and positioning mode according to task requirements, and obtain positioning information based on the navigation and positioning mode; the control system is used to , to control the navigation of the underwater vehicle. As a whole, it can significantly improve the stability of rolling and ensure the accuracy of data collection. At the same time, it has the characteristics of high navigation accuracy, strong independent decision-making ability, and good maneuverability. It can effectively improve the cruising range and solve the control system of existing underwater vehicles. There are technical problems such as complex line layout, difficult disassembly and maintenance, and high cost.

Description

technical field [0001] The present application relates to the technical field of underwater navigation, and in particular, to a flat underwater vehicle. Background technique [0002] With the deepening of human exploration of the ocean and the development of marine economy, more and more attention has been paid to the research and development of underwater unmanned vehicles. According to the different mission objectives and ways of use, unmanned underwater vehicles can be roughly divided into two categories: cabled and cableless. Cabled underwater vehicles are mostly used for short-range detection and underwater collection and maintenance work, and the manipulation and energy supply are realized through underwater cable transmission. Cableless underwater vehicles are mostly used for medium and long-distance seabed topography and resource surveys. They realize underwater navigation through their own batteries, and collect data through their own related detection equipment. ...
