Problems solved by technology

When the winged underwater vehicle is propelled by the propeller, due to the lift of the wing, it is difficult to ensure high-precision navigation at a fixed depth, and the wing will increase the additional mass of the attachment, which will weaken the maneuverability of the whole machine

Embodiment 1

[0024] Embodiment 1: A kind of large-scale underwater vehicle that possesses self-abandoning type wing provided by the present invention, its overall appearance is as follows figure 1 As shown, it includes bow assembly 1, middle assembly 2, tail assembly 3 and wing unit 12; see figure 2 , the bow assembly 1 includes a cable throwing module 4, a bow shell 5, a bow connecting ring 6, a front buoyancy adjustment module 7, a front connection fixing block 8, and a front glass fiber reinforced plastic shell 9; the cable throwing module 4 and the bow shell 5 The front end is fixedly connected by eight circumferential bolts; the bow shell 5 and the front glass fiber reinforced plastic shell 9 are connected by the bow connecting ring 6, and the connection method is fixedly connected by ten bolts evenly distributed in the circumferential direction; the front connecting fixed block 8 has eight one, and have a through hole, between the front glass fiber reinforced plastic shell 9, the fr...

Embodiment 2

[0030] Embodiment 2: The dual-buoyancy hybrid large-scale heavy-duty underwater vehicle provided by Embodiment 1 is used to carry out underwater gliding detection navigation without propulsion, and the propeller is always closed.

[0031] The process of diving is: before the diving process, the underwater vehicle floats on the water surface in a state of neutral buoyancy. After the diving mode is turned on, the control module 23 sends a signal to control the attitude adjustment module 22 to adjust the attitude, and then controls the front and rear buoyancy adjustment modules. 7, 13 reduce the overall buoyancy of the underwater vehicle, thereby realizing the dive. During the dive, the sensor carried by the control module 23 controls the signal measurement and saves, and at the same time controls the attitude adjustment module 22 and the cross rudder 17 to ensure the gliding attitude and course;

[0032] The process of floating is: when the underwater vehicle dives to the target...

Embodiment 3

[0036] Embodiment 3: The dual-buoyancy hybrid large-scale heavy-duty underwater vehicle provided by Embodiment 1 is used to carry out underwater propulsion and depth-fixed exploration navigation.

[0037] Dive to the target depth process: after the dive mode is turned on, the control module 23 sends a signal to control the attitude adjustment module 22 to adjust the attitude, and then controls the front and rear buoyancy adjustment modules 7 and 13 to reduce the overall buoyancy of the underwater vehicle, thereby realizing the dive;

[0038] Depth-fixed detection cruising process: After diving to the target depth, the control module 23 controls the mounted sensor to measure and save the signal, and at the same time controls the attitude adjustment module 22 and the cross rudder 17 to ensure the gliding attitude and heading, so that the underwater vehicle is always at the target Depth range, in level sailing state;

[0039] Floating process: When the depth-fixed detection cruis...

Description

technical field [0001] The invention belongs to the field of new marine vehicles, and relates to a winged underwater vehicle, in particular to a large underwater vehicle with a self-abandoning wing. Background technique [0002] As an important tool equipped with marine physical information sensors, underwater vehicle platform technology has developed rapidly. Its strong endurance, long range, and strong concealment make it very suitable for the measurement of marine biological, chemical, and physical parameters. It is one of the most commonly used underwater mobile observation platforms, but the endurance of underwater vehicles that rely solely on propeller propulsion is relatively limited, and hybrid drive underwater vehicles that combine buoyancy drive and propeller drive have emerged as the times require. [0003] Internationally, relatively mature hybrid-drive underwater gliders mainly include Slocum G3Glider developed by Webb Company of the United States, AUV-Glider of...
