2results about How to "Change posture" patented technology

The invention discloses a magnetic wave making machine body structure which comprises a machine body assembly, the machine body assembly comprises an upper supporting frame, the middle of the upper supporting frame is rotationally connected with a wave pushing plate through a rotating assembly, magnetic power driving devices are arranged on the two sides of the upper supporting frame, and therefore the machine body assembly moves along an induction plate; the rotating assembly comprises paired rotating mechanisms, the paired rotating mechanisms are connected to the lower supporting frame and located on the back face of the wave pushing plate, the output ends of the rotating mechanisms are connected with the wave pushing plate, and when the output directions of the rotating mechanisms are opposite, the posture of the wave pushing plate is changed; the upper supporting frame provides a stable supporting point for the wave pushing plate, and flexible rotation is guaranteed to generate various wave forms. The paired rotating mechanisms can accurately control the wave pushing plate to move, vivid sea waves can be simulated, lateral force can be overcome in an auxiliary mode to prevent the machine body from inclining, and therefore the driving problem of traditional wave making equipment is solved, the magnetic power application blank is filled up, and the wave making machine performance and user experience are improved.

This invention provides an AUV multi-thrust propulsion system, comprising stabilizers, auxiliary rim thrusters, an AUV stern body, main rim thrusters, fairings, connecting discs, and a tail-mounted connecting frame. The main rim thrusters are fixedly connected to the rear end of the AUV stern body via the connecting discs. The fairings are positioned behind the blades of the main rim thrusters. The four auxiliary rim thrusters are uniformly fixed in a cross shape around the circumference of the AUV stern body. The four stabilizers are arranged in an X-shape on the stern body, staggered and evenly spaced with the four auxiliary rim thrusters. The advantages of this invention are increased maneuverability and controllability while reducing the complexity of the drive mechanism, saving stern space, and increasing the power, maneuverability, and system redundancy of the propulsion system by using multiple rim thrusters, thereby improving the safety, stability, controllability, and mission execution efficiency of the AUV in complex underwater environments.
