Problems solved by technology

Conventional detection AUVs are usually equipped with only one set of horizontal propellers, one set of horizontal steering gear, and one set of vertical steering gear, which determines that it can only perform motion detection in water, and cannot hover in a fixed place in the ocean control or close-in observation of suspicious targets

Embodiment Construction

[0052] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0053] In the present invention, a lateral propeller is respectively added to the lateral direction of the bow section and the stern section of the submerged body, and a set of vertical propellers are installed in the middle of the submerged body. With this configuration, the long-range AUV can approach the target at a low speed for alignment observation or hover control to process the target. The invention breaks through the traditional AUV motion control technology and has reached the domestic leading level.

[0054] A low-speed approaching and hovering submarine body for an underwater target combined with multiple propellers, comprising: a horizontal propeller 10, a vertical propeller 11 and two lateral propellers 12;

[0055] The horizontal thruster 10 is fixedly connected to the positive tail of the submerged body, and its axis coincides with the axi...

Abstract

The invention discloses an underwater target low-speed approaching and hovering submarine body combining multiple propellers. The submarine body is characterized by further comprising a horizontal propeller, a vertical propeller and two lateral propellers, the horizontal propeller is fixedly connected to the right tail of the submarine body, and the axis of the horizontal propeller coincides with that of the submarine body; a vertical channel is formed in the buoyant center of the submarine body, and the vertical propeller is fixedly connected to the inner wall of the vertical channel; horizontal channels horizontally penetrating the submarine body are formed in the bow segment and the stern segment of the submarine body respectively, one lateral propeller is fixedly connected to the inner wall of the horizontal channel of the bow segment, the other lateral propeller is fixedly connected to the inner wall of the horizontal channel of the stern segment, and airscrews of the two lateral propellers are opposite in direction. The submarine body is used for achieving the effect of accurate hovering control when a long-distance AUV conducts close-range alignment observation or object processing around a suspicious underwater target.

Description

technical field [0001] The invention relates to the technical field of underwater navigation; in particular, it relates to an underwater target approaching and hovering submerged vehicle combined with multiple propellers at low speed. Background technique [0002] Long-range AUV is a cable-free underwater robot, which is widely used in ocean exploration, ocean hydrological detection, underwater engineering, underwater target processing and other fields. Conventional detection AUVs are usually equipped with only one set of horizontal propellers, one set of horizontal steering gear, and one set of vertical steering gear, which determines that it can only perform motion detection in water, and cannot hover in a fixed place in the ocean Control or approach and observe suspicious targets. With the increasing demand for long-range AUVs in the military, higher requirements are put forward for the motion control of long-range AUVs. In order to expand the operation function and app...
