Underwater helicopter

Abstract

The invention provides an underwater helicopter. A main body part of the underwater helicopter is composed of an upper cover, a lower cover, thrusters, a titanium ring, a control barrel, a fixing frame, welding blocks, connecting blocks, fixing blocks and screw rods. The control barrel is fixed to the fixing frame. The welding blocks are welded to the tail ends of supporting rods of the fixing frame. The welding blocks, the connecting blocks and the titanium ring are fixed through bolts and nuts. The upper cover, the lower cover and the titanium ring are fixed with bolts penetrating through through holes. If the underwater helicopter needs to dive downwards or float upwards, only the horizontally-upward thrusters need to be controlled to rotate; if the underwater helicopter needs to go forward or backward, only the horizontal thrusters need to be controlled to rotate in a forward and reverse mode; and if the underwater helicopter needs to hover, only the horizontally-upward thrusters need to be controlled to offset the underwater mass of the underwater helicopter at the certain rotating speed. The underwater helicopter is easy and convenient to operate and very flexible.

Description

technical field [0001] The invention relates to a submersible, in particular to a 3000-meter-class submersible adopting dish-shaped design and underwater wireless high-speed optical communication technology. Background technique [0002] Operations and surveys in the underwater environment, especially in the deep sea, have always been a problem. With the advancement of technology, more and more underwater robots have been created, carrying manipulators, sonar, cameras and data acquisition sensors to explore the water bottom. down world. Due to the different underwater areas explored, underwater robots are divided into propellers and non-propellers, cables and cables, underwater crawler walking and underwater fixed-point work (without mobility) and so on. The shape of underwater robots is also mostly rectangular, cylindrical or streamlined. Most of the robots with mobility adopt these shape designs to facilitate the carrying of detection equipment or reduce fluid resistance....

AI Technical Summary

Problems solved by technology

Therefore, most of the current underwater robots with mobile operation capabilities have the following two deficiencies: 1. Poor flexibility; 2. Unable to achieve arbitrary hovering

[0004] In addition, at present, most of the major underwater vehicles in China use cable communication, so they will have a long cable, which will affect the movement of underwater robots.
