Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figures 1-4 , an omnidirectional navigation decoy device for resisting drones, including a bottom plate 1 and a connecting chassis 4. A limit cylinder seat 2 is fixedly connected to the upper part of the bottom plate 1. A positioning cylinder 3 is slidably arranged in the limit cylinder seat 2. A decoy mechanism is connected to the upper part of the positioning cylinder 3. A connection mechanism is arranged on the upper part of the bottom plate 1. Four positioning columns 7 are fixedly connected to the lower part of the connecting chassis 4. The connection mechanism restricts the movement of the positioning columns 7;

[0022] The connection mechanism includes a fixing plate 8. The fixing plate 8 is L-shaped. An electric telescopic rod 9 is fixedly connected to the inner wall of the fixing plate 8. A spring 10 is arranged on the outer wall of the electric telescopic rod 9. One end of the spring 10 is fixedly arranged on the inner wall of the fixing plate 8;

[0023] The connection mechanism further includes a fixing fastener 11. One end of the electric telescopic rod 9 and one end of the spring 10 are fixedly connected to the inner wall of the fixing fastener 11. When the electric telescopic rod 9 contracts, through the tensile force of the spring 10, the fixing fastener 11 can be quickly pulled to move. A pulley 12 is arranged at the lower part of the fixing fastener 11. The outer wall of the pulley 12 is in contact with the upper wall of the bottom plate 1, which is convenient for the pulley 12 to move on the upper part of the bottom plate 1 and reduces the resistance when the electric telescopic rod 9 moves, saving energy;

[0024] The decoy mechanism includes a rotating platform 5. The lower part of the rotating platform 5 is fixedly connected to the positioning cylinder 3. When the decoy machine 6 needs to rotate, the rotating platform 5 is rotated, so that the positioning cylinder 3 arranged at the lower part of the rotating platform 5 rotates in the limit cylinder seat 2. Through the restriction of the positioning cylinder 3 in the limit cylinder seat 2, it is avoided that when the connecting chassis 4 moves vertically, the fixing fastener 11 releases the restriction on the fixing sleeve 15, and a through hole is opened in the connecting chassis 4, and the outer wall of the positioning cylinder 3 is arranged in the through hole of the connecting chassis 4;

[0025] A connecting plate 16 is fixedly connected to the upper part of the rotating platform 5. A decoy machine 6 is fixedly connected to the upper part of the connecting plate 16;

[0026] A fixing ring 14 is fixedly connected to the lower part of the positioning column 7, a fixing sleeve 15 is fixedly connected to the lower part of the fixing ring 14, a limiting column 13 is arranged below the fixing sleeve 15, the bottom of the limiting column 13 is fixedly connected to the upper wall of the bottom plate 1, and the upper part of the fixing fastener 11 is of a conical structure. When the fixing fastener 11 restricts the fixing sleeve 15, the conical structure of the upper part of the fixing fastener 11 is in contact with the upper wall of the fixing sleeve 15, and together with the conical structure of the upper part of the fixing fastener 11 abutting against the outer wall of the fixing ring 14, the fixing sleeve 15 is jointly restricted.

[0027] The functional principle of the present utility model can be described through the following operation modes:

[0028] During use, the positioning cylinder 3 at the lower part of the connecting chassis 4 is lowered into the limit cylinder seat 2, then the fixing sleeve 15 arranged at the lower part of the positioning column 7 is abutted against the limiting column 13, then the electric telescopic rod 9 is driven to make the electric telescopic rod 9 push the two fixing fasteners 11 to move towards each other, and then the fixing fasteners 11 are abutted against the outer wall of the fixing ring 14, so as to restrict the movement of the fixing sleeve 15. When the UAV navigation deception device needs to be disassembled, the electric telescopic rod 9 is turned on, and together with the contraction force of the spring 10, the fixing fasteners 11 quickly release the restriction on the fixing sleeve 15.

[0029] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
