Abstract

The present invention provides a simple underwater motion device based on fluid drive, including a control device, a propeller support device, a drive mechanism and a depth adjustment assembly. The depth adjustment assembly and the drive mechanism are all installed on the propeller support device, so the The depth adjustment assembly includes a fluid change generator, a second cavity and a seventh pipeline, the fluid change generator is connected to the second cavity through the seventh pipeline, and when the fluid in the second cavity increases, the The buoyancy of the device becomes larger; when the fluid in the second cavity becomes less, the buoyancy of the moving device becomes smaller; further, the adjustment of the navigation depth of the entire device in water is realized, and the driving force is provided for the navigation through the driving mechanism; the present invention adopts the fluid-based driving The mechanism realizes the navigation of the motion device, and compared with the prior art, the motion device has low noise, low power consumption and wide application range.

Description

technical field [0001] The invention relates to the technical field of underwater vehicles, in particular, to a simple underwater motion device driven by fluid. Background technique [0002] The efficient swimming mode of fish has always been the goal pursued by human beings. With the continuous deepening of research on underwater sports devices, more and more researchers have begun to study underwater bionic sports devices. Compared with the traditional propeller propulsion method, the fish has the advantages of low noise, high maneuverability and high efficiency during swimming, which can meet the requirements of underwater vehicles to cope with complex sea conditions. Therefore, underwater bionic propulsion technology has become an important research direction of underwater propulsion technology. [0003] With the rapid development of science and technology, higher requirements are put forward for the concealment and maneuverability of underwater vehicles. The tradition...
