Eight-propeller remote control unmanned submersible in dual-power layout mode

Abstract

The invention discloses a dual-power layout mode eight-propeller remote control unmanned submersible which comprises a machine body, four horizontal propellers, two vertical propellers and two adjustable propellers, and the four horizontal propellers, the two vertical propellers and the two adjustable propellers are fixed to the machine body. The two adjustable propellers and the two side plates are arranged in a one-to-one correspondence mode, and the adjustable propellers are fixed to the side plates in the vertical direction and the transverse direction in an adjustable mode. A dual-power layout is adopted: a 4 + 4 mode and a 6 + 2 mode are adopted, and can be switched within one minute, so that the device is suitable for two application directions, and different task requirements during each time of going out of sea are met; the 4 + 4 mode can ensure sufficient load and posture adjusting capability; and the 6 + 2 mode can greatly improve the operation speed.

Description

technical field [0001] The invention relates to the technical field of remote-controlled unmanned submersibles, in particular to an eight-propeller remote-controlled unmanned submersible in a dual-power layout mode. Background technique [0002] Underwater robots (also known as remote-controlled unmanned submersibles, English name Remote Operated Vehicle, abbreviated as ROV) currently have two main application directions: the first one is equipped with various mechanical arms, sonar, testing instruments and other equipment, and dives into the water. In order to perform detection and grabbing tasks, ROVs for such applications require multiple vertical propellers to increase their load capacity, and multiple vertical propellers can adjust their posture after adding accessories (such as two vertical propellers at the front and rear). The propeller adjusts the pitch attitude, and the two vertical thrusters on the left and right adjust the roll attitude); the second type is only ...

AI Technical Summary

Problems solved by technology

[0003] For ROVs currently on the market, the mainstream thruster layout is divided into two types: one is the "4+2" mode, that is, 4 horizontal thrusters + 2 vertical thrusters, and this mode can only be used in the second type. Good application is achieved in the application, but after being equipped with various peripheral accessories, since there are only 2 vertical propellers, this type of ROV has defects in load capacity and attitude adjustment ability; the other is "4+ 4" mode, that is, 4 horizontal propellers + 4 vertical propellers, although this mode can be adapted to the above two applications, but when performing the second fast driving application, because there is not much load, 4 The vertical thrusters are relatively redundant (two are unnecessary), resulting in a waste of cost

[0004] It is impossible for any ROV to only do a single application, but before going to sea every time, the task is determined and single, either equipped with multiple accessories for detection, or quick search

Therefore, a new type of ROV is needed, which not only has a large load capacity, but also has a fast horizontal movement capability, and too many propellers will not cause redundancy and cost waste
