Problems solved by technology

When the underwater glider enters the water from the air, due to the large frontal area of ​​the stretched wings, it will bear a large hydrodynamic impact, and it is easy to be damaged in the slap in the water; moreover, the stretched wings cause the underwater glider to It takes up a lot of space, and it also increases the difficulty of carrying and arranging the aircraft

Embodiment Construction

[0018] like Figure 1 to Figure 5 As shown, an air-dropped underwater glider based on motor-driven wingspan includes a housing 1, a signal device 2, and a buoyancy adjustment device 3, a roll attitude adjustment device 4, and a pitch attitude adjustment device 5 arranged in the housing 1. And control device 6, also comprises hang glider stretching device 7, and described hang glider stretching device 7 comprises hang glider 71, worm screw 72 and is used to drive the spread wing control motor 73 that worm screw 72 rotates, and described hang glider 71 is positioned at housing 1 The inner end is a worm wheel 74 that cooperates with the worm 72, and the worm wheel 74 is fixed in the housing 1 through a rotating shaft 75. Deep groove ball bearings are arranged between them, and under unconstrained conditions, the worm gear 74 engages with the worm screw 72 and can rotate freely around its rotating shaft 75. The wing control motor 73 drives the worm screw 72 to rotate, and the Coo...

Abstract

The invention discloses a motor-driven wing expansion based air-drop underwater glider, which comprises a shell, a signal device, a buoyancy adjusting device, a roll attitude adjusting device, a pitchattitude adjusting device, a control device and a gliding wing expansion device. The buoyancy adjusting device, the roll attitude adjusting device, the pitch attitude adjusting device and the controldevice are arranged in the shell. The gliding wing expansion device comprises gliding wings, a worm and a wing expansion control motor, and the wing expansion control motor is used for driving the worm to rotate. Worm gears matched with the worm are arranged at ends, in the shell, of the gliding wings and fixed in the shell through rotating shafts. The motor-driven wing expansion based air-drop underwater glider has advantages that water-entry impact force of the wings is reduced, adaptability to air-drop application is realized, and the wings are in a collected state before air drop, so thatsmall occupied space is realized, the glider is convenient for an airplane to carry, and high timeliness is realized.

Description

technical field [0001] The invention relates to an underwater glider, in particular to an air-drop underwater glider based on motor-driven wingspan. Background technique [0002] Underwater glider is a new type of marine exploration equipment. It realizes gliding motion with low energy consumption through net buoyancy and center of mass adjustment. It has the characteristics of high efficiency, strong endurance, and long detection time. Wide range of application requirements. Existing underwater gliders are generally carried by the mother ship for deployment. However, it takes a long time for the mother ship to reach the designated sea area, which restricts its application in emergencies, such as the black box search of the crashed aircraft, the detection of accidental natural phenomena, etc. . Therefore, improving the timeliness of underwater glider deployment and enabling single or multiple underwater gliders to reach designated sea areas quickly will expand the applicat...
