Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 4, the wing for ensuring continuity of an air-drop type underwater glider main body disclosed by the invention comprises a fuselage 1 and a wing extension device 2, wherein the wing extension device comprises wings 22, a connecting plate 23, a first elastic member 24, a rotating shaft 25, a water-soluble fiber member 21 and a locking mechanism 26 for locking the wings in an unfolded state, the connecting plate 23 is fixed on two sides of the fuselage 1, one end of each wing 22 is rotatably fixed on the connecting plate 23 through the rotating shaft 25, the other end of each wing 22 is fixed outside the fuselage 1 through the water-soluble fiber member 21, and the first elastic member 24 is arranged between the connecting plate 23 and the wing 22 and can unfold the wings 22 through elasticity.

Further, one end of the wing 22 fixed to the rotating shaft 25 is an arc-shaped structure, a slot is formed in the arc-shaped structure, the locking mechanism 26 includes a cylinder 261, a locking pin 263 and a second elastic member 262, the cylinder 261 is fixed to the fuselage 1 or the connecting plate 23, the second elastic member 262 is disposed in the cylinder 261, the locking pin 263 is disposed between the second elastic member 262 and the arc-shaped structure, the locking pin 263 can axially slide in the cylinder 261, and when the wing 22 is unfolded, the locking pin 263 can enter the slot under the pushing of the second elastic member 262. When the wing 22 is in the folded state, the locking pin 263 presses the second elastic element 262 against the arc-shaped structure of the wing 22; when the wing 22 is in the unfolding state, the locking pin 263 is clamped into the clamping groove of the arc-shaped structure under the action of the second elastic element 262, so that the wing 22 can be fixed in the unfolding state, the phenomenon that the wing 22 swings due to the impact of water flow after being unfolded is avoided, and the glider can be better supported to work underwater.

Further, the first elastic element 24 is a spring, the spring is sleeved outside the rotating shaft 25, one end of the spring is fixed on the wing 22, and the other end of the spring is fixed on the connecting plate 23, when the wing 22 is in a folded state, the spring can be unfolded.

Further, the water-soluble fiber part 21 winds and fixes one end of the wing 22 far away from the rotating shaft 25 outside the fuselage 1, and after the glider enters water, the water-soluble fiber part 21 is dissolved in the water, and the wing 22 is not fixed any more. The water-soluble fiber is used for fixing the wings in a winding mode, and compared with other fixing modes of bonding the wings and the fuselage by using water-soluble materials, the water-soluble fiber wing fixing device has higher water-meeting dissolving speed, and can enable the glider to expand the wings more quickly after entering water to start normal work.

The working process of the invention is as follows: when the glider is dropped off, the wings are wound on the two sides of the fuselage by the water-soluble fiber parts, so that the wings are in a folded state, after the glider enters water, the water-soluble fiber parts are dissolved in water, the wings are unfolded under the action of the first elastic part, and after the wings are unfolded to a certain position, the locking pins are bounced and clamped into the clamping grooves of the arc-shaped structures of the wings, so that the wings are fixed in the unfolded state.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
