Problems solved by technology

In recent years, some domestic scientific research institutes have started the research and development of large-scale heavy-duty underwater gliding, but related products have shortcomings such as high resistance and high energy consumption. The patent number is 201810508824.8, which discloses a large-scale heavy-duty hybrid drive underwater glider, including the glider fuselage, buoyancy adjustment device, attitude adjustment device, folding wing device, energy module, etc. The glider has the disadvantage of less detection equipment, but it uses a single buoyancy adjustment device, which is located at the front of the fuselage, so that the buoyancy adjustment will inevitably affect the pitching attitude of the underwater glider, and the influence must be controlled by the attitude adjustment device. Compensate for the waste of energy

Embodiment 1

[0029] Embodiment 1: A kind of underwater glider that can preset large load underwater 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 load compartment assembly S; see figure 2 , the bow assembly 1 includes the cable throwing module 4, the bow shell 5, the bow connecting ring 6, the front buoyancy adjustment module 7, the front connection fixing block 8, and the front glass fiber reinforced plastic shell 9; the cable throwing module 4 and the front end of the bow shell 5 It 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; there are eight front connection fixing blocks 8 , and have a through hole, between the front glass fiber reinforced plast...

Embodiment 2

[0042] Embodiment 2: The underwater vehicle provided by the embodiment is used to carry out underwater propulsion and depth-fixed exploration voyage.

[0043] Dive to the target depth process: after the dive mode is turned on, the control module sends a signal to control the attitude adjustment module to adjust the attitude, and then controls the front and rear buoyancy adjustment modules to reduce the overall buoyancy of the underwater vehicle, thereby realizing the dive;

[0044] Depth-fixed detection cruise process: After diving to the target depth, the control module controls the mounted sensor to measure and save the signal, and at the same time controls the attitude adjustment module and cross rudder to ensure the gliding attitude and heading, so that the underwater vehicle is always in the target depth range, in level sailing condition;

[0045] Floating process: After the depth-fixed detection and cruising operation is completed, the control module sends commands to co...

Abstract

The invention discloses an underwater glider capable of presetting large loads underwater. The underwater glider comprises a bow assembly, a load cabin section assembly, a middle assembly, a tail assembly and a wing unit. The glider is capable of carrying the large load and presetting the large load underwater in an unmanned manner, the wing unit can control the change of an angle of attack of a trailing edge, and the control ability of the whole glider is improved; and in addition, according to the large underwater glider, double buoyancy adjusting modules are adopted, the two identical buoyancy adjusting modules are located in front of and behind the floating center of the glider, and can be turned on at the same time, so that the total oil drainage time and oil return time of the gliderare shortened, and the gliding performance of the glider is increased.

Description

technical field [0001] The invention belongs to the field of underwater vehicles, in particular to an underwater glider capable of presetting a large load underwater. Background technique [0002] With the proposal of the "ocean power" strategy, it has become more and more important to develop the ocean, understand the ocean, and manage the ocean. Marine scientific research has important practical significance for understanding the natural phenomena of the ocean. 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...
